We are delighted to present our<br />
<strong>Annual</strong> <strong>Research</strong> <strong>Report</strong> for <strong>2005</strong>,<br />
which records another year of<br />
important achievements and<br />
significant progress in cancer research.<br />
It contains in-depth reviews of recent,<br />
exciting developments in several areas<br />
of our work, and provides addresses<br />
for various web resources which give<br />
comprehensive information on all<br />
aspects of our activities.<br />
<strong>The</strong> Institute of Cancer <strong>Research</strong> and<br />
<strong>The</strong> <strong>Royal</strong> <strong>Marsden</strong> NHS Foundation<br />
Trust form the largest Comprehensive<br />
Cancer Centre in Europe, and one<br />
of the largest in the world, which<br />
has an outstanding national and<br />
international reputation. Our<br />
mission, "to relieve human suffering<br />
by pursuing excellence in the fight<br />
against cancer", is carried out within<br />
a framework of activities in research<br />
and development, education and<br />
training, and the treatment and care<br />
of people affected by cancer.<br />
Our clinicians and scientists<br />
collaborate through the <strong>Joint</strong> <strong>Research</strong><br />
Committee on research strategy and<br />
priorities. Recent developments<br />
supported by the hospital and <strong>The</strong><br />
Institute include investment in<br />
academic surgery with the newly<br />
established Paul Hamlyn Chair of<br />
Surgery, held jointly between the <strong>Royal</strong><br />
<strong>Marsden</strong>, <strong>The</strong> Institute and Imperial<br />
College by Professor Sir Ara Darzi, the<br />
highly successful performance of the<br />
Oak Foundation Drug Development<br />
Unit and investment in a PET/CT<br />
scanner to support imaging research<br />
and the Drug Development<br />
Programme. We work, like other<br />
world-class centres of excellence, in<br />
a truly international context and in<br />
partnership with many research<br />
institutions and funding agencies.<br />

<strong>The</strong> availability of the sequence of<br />
the human genome, and of the<br />
many other genomes which help<br />
us to understand the meaning of the<br />
blueprint that makes each of us, has<br />
enormous implications for cancer<br />
research. It means that we can now<br />
systematically identify all of the genes<br />
involved in the progression from a<br />
normal cell to a tumour cell. <strong>The</strong><br />
challenge for the future is to exploit<br />
this genetic information for the<br />
benefit of cancer patients and our<br />
joint scientific strategy seeks to put<br />
in place the skills and resources<br />
necessary to do this. This is entirely<br />
appropriate since it was Institute<br />
scientists, Professors Peter Brookes<br />
and Philip Lawley, who, some forty<br />
years ago, first showed that chemicals<br />
that cause cancer act by damaging<br />
DNA, from which our genes are<br />
made. This heritage continues with<br />
the Cancer Genome Project, initiated<br />
by Institute scientists Professor Mike<br />
Stratton and Dr Richard Wooster, and<br />
undertaken in partnership with the<br />
Wellcome Trust’s Sanger Institute.<br />
It will provide us, for the first time,<br />
with a complete description of the<br />

will target these precisely defined<br />
molecular abnormalities in the search<br />
for new and specific anticancer drugs.<br />
<strong>Research</strong> highlights<br />
disease, and the results thus far are<br />
both exciting and informative.<br />
Our strategy seeks to exploit this<br />
information in three areas: genetic<br />
epidemiology, molecular pathology<br />
and therapeutic development. In<br />
genetic epidemiology, information<br />
from the Cancer Genome Project and<br />
other genetic analyses will be used in<br />
very large, population-based studies<br />
to try to discover the environmental<br />
and lifestyle factors that contribute<br />
to the development of cancer. Some<br />
we know, smoking being the most<br />
obvious, but for many cancers our<br />
present understanding of causation<br />
is rudimentary. Our work in<br />
molecular pathology will use the<br />
genetic knowledge to devise not only<br />
new and more sensitive ways of<br />
detecting the disease earlier but also<br />
much more precise ways of staging its<br />
progression, with consequent benefit<br />
to patient management. Knowing all<br />
the mutations in a particular tumour<br />
will help to identify the molecular<br />
targets for therapeutic intervention.<br />
Our strategy in drug development<br />
<strong>The</strong> development of new therapies<br />
for cancer depends upon our<br />
ever-increasing knowledge of the<br />
molecular basis of the disease. Many<br />
of the current generation of drugs act<br />
by inducing a process known as<br />
apoptosis, or programmed cell death,<br />
and a major problem that affects<br />
their use is that in many advanced<br />
tumours the molecular pathways<br />
that mediate apoptosis become<br />
inactivated, and thus the tumours<br />
acquire resistance to the therapeutic<br />
agent. We therefore need a detailed<br />
understanding of the mechanisms<br />
of apoptosis so that we can overcome<br />
this resistance to drugs, and to<br />
radiotherapy. Pascal Meier, a young<br />
investigator in the Breakthrough<br />
Toby Robins Breast Cancer <strong>Research</strong><br />
Centre, who was recently granted a<br />
non-time-limited appointment to<br />
<strong>The</strong> Institute’s Faculty, has been<br />
making significant contributions to<br />
this endeavour. His research focuses<br />
on a family of proteins called IAPs<br />
(for Inhibitors of Apoptosis) which<br />
play key roles in preventing the<br />
activation of the death pathway in<br />
healthy cells. His work has shown that,<br />
contrary to previous understanding,<br />
different members of the IAP protein<br />
family work by quite different<br />
mechanisms thus exposing further<br />
complexity in the process which can<br />
hopefully be exploited to overcome<br />
resistance to therapy.<br />
An excellent example of how<br />
increased understanding of the<br />
molecular basis of cancer can rapidly<br />
lead to new therapeutic approaches<br />
is provided by work led by Alan<br />
Ashworth, the Director of the<br />
Breakthrough Centre, in collaboration<br />
with the biotechnology company<br />
KuDOS Pharmaceuticals, which is now<br />
a subsidiary of AstraZeneca. Some ten<br />

REVIEW OF <strong>2005</strong><br />
Crystal structure of<br />
the dimeric HSP90<br />
chaperone in the<br />
closed ATP-bound<br />
state (blue and gold<br />
molecules), in<br />
complex with the<br />
p23 regulatory cochaperone<br />
(red and<br />
green molecules),<br />
which only binds<br />
to HSP90 in this<br />
conformation.<br />
<strong>The</strong> crystal<br />
structure shows<br />
how HSP90 utilises<br />
ATP in its activation<br />
of client proteins<br />
such as oncogenic<br />
protein kinases,<br />
and explains why<br />
HSP90 ATPase<br />
inhibitors prevent<br />
this.<br />
years ago he, and Mike Stratton,<br />
Chairman of the Section of Cancer<br />
Genetics, succeeded in isolating the<br />
breast cancer susceptibility gene<br />
BRCA2. <strong>The</strong> new work shows that<br />
tumours carrying mutations in<br />
BRCA2, and BRCA1, which render<br />
the cells deficient in a particular<br />
pathway for repairing damage to<br />
DNA, are exquisitely sensitive to<br />
drugs which inhibit the enzyme<br />
poly-ADP-ribose polymerase, itself<br />
a component of another repair<br />
pathway. <strong>The</strong>se drugs have now<br />
entered Phase I clinical trials in the<br />
Oak Foundation Drug Development<br />
Unit of the <strong>Royal</strong> <strong>Marsden</strong> with a<br />
rapidity that exemplifies the value<br />
of collaborations between our<br />
scientists and clinicians and the<br />
biotechnology industry.<br />
<strong>The</strong> outstanding success of the<br />
Breakthrough Centre over the six<br />
years since its inauguration has been<br />
recognised by <strong>The</strong> Institute, and by<br />
Breakthrough Breast Cancer, in the<br />
signing of a new agreement which<br />
allocates additional space in the<br />
Chester Beatty Laboratories to the<br />
Centre so that two additional teams<br />
of breast cancer researchers can<br />
be recruited.<br />
<strong>The</strong> Institute’s Structural Biology<br />
Initiative continues to be an<br />
outstanding success. David Barford,<br />
Co-Chairman of the Section of<br />
Structural Biology, has made<br />
significant progress in elucidating the<br />
structure of the Anaphase Promoting<br />
Complex. This large molecular<br />
machine is involved in destroying key<br />
proteins at precise points in the cell<br />
cycle, and thus plays an essential role<br />
in a process which is almost always<br />
deregulated in tumour cells. <strong>The</strong>re<br />
has recently been great excitement<br />
throughout biology at the discovery<br />
of a totally new mechanism for<br />
regulating gene expression which<br />
involves small RNA molecules called<br />
microRNAs. <strong>The</strong>se act to cause either<br />
the degradation of mRNAs, or to<br />
block their translation, and there<br />
is highly suggestive evidence that<br />
these processes play a role in cancer.<br />
Barford’s group have determined<br />
the structure of one of the key<br />
components of the degradation<br />
pathway thus revealing many details<br />
of the mechanism.<br />
Meanwhile, Laurence Pearl, the<br />
other Co-Chairman of the Section,<br />
has completed a decade long project<br />
to determine the entire structure of<br />
the molecular chaperone HSP90. His<br />
work has provided important new<br />
information on the mechanism by<br />
which it facilitates the proper folding<br />
of many proteins involved in tumour<br />

REVIEW OF <strong>2005</strong><br />
cell growth. HSP90 is a key target of<br />
<strong>The</strong> Institute’s drug development<br />
programme and clinical trials of the<br />
inhibitor 17-AAG have given highly<br />
encouraging results which strongly<br />
support the notion that blocking the<br />
action of the chaperone will be<br />
beneficial. Even more importantly,<br />
a new, small molecule inhibitor,<br />
developed by Paul Workman and his<br />
colleagues in the Cancer <strong>Research</strong> UK<br />
<strong>The</strong> Sir Richard Doll Building<br />
Centre for Cancer <strong>The</strong>rapeutics, in<br />
collaboration with the biotechnology<br />
company Vernalis, has been licensed<br />
to Novartis, one of the world’s largest<br />
pharmaceutical companies, who have<br />
announced that they intend to rapidly<br />
take it into clinical development.<br />
Over the last eighteen months, three<br />
anticancer drugs developed in the<br />
Centre for Cancer <strong>The</strong>rapeutics have<br />
been licensed to major pharmaceutical<br />
companies. In addition to the HSP90<br />
inhibitor, molecules which block the<br />
action of Protein Kinase B, also<br />
known as AKT, developed in<br />
collaboration with the biotechnology<br />
company Astex, have been licensed to<br />
AstraZeneca, while inhibitors of PI3<br />
Kinase, which acts in the same signal<br />
transduction pathway, developed<br />
with PIramed, a company which<br />
<strong>The</strong> Institute helped to found, have<br />
been licensed to Genentech. It is<br />
noteworthy that two of these three<br />
programmes depended on extensive<br />
input from the structural biologists.<br />
To achieve three such deals in such<br />
a short space of time is extraordinary,<br />
and is a great tribute to the quality<br />
of <strong>The</strong> Institute’s science, and to the<br />
efficiency and skill of its Enterprise<br />
Unit, without which we would not be<br />
able to engage so effectively with our<br />
industrial collaborators.<br />
In order to further strengthen our<br />
work in Structural Biology we have<br />
recruited three new Faculty members<br />
who work in this area, and have<br />
invested significant amounts of<br />
money in a new Cryo-Electron<br />
Microscopy facility which will allow<br />
us to study the structures of the very<br />
large protein complexes that mediate<br />
most of the key processes within a cell.<br />
While the treatment of cancer will<br />
remain a high priority for the<br />
foreseeable future, in the long term<br />
we need to understand what does,<br />
and does not, cause the disease, so<br />
that we can develop effective<br />
strategies for its prevention. In order<br />
to increase our capacity to undertake<br />
both such epidemiological studies,<br />
and work on large-scale clinical trials,<br />
<strong>The</strong> Institute has opened a new<br />
building on its Sutton campus. This<br />
will be called the Sir Richard Doll<br />
building in memory of the preeminent<br />
epidemiologist of the<br />
twentieth century, who served as<br />
Chairman of <strong>The</strong> Institute from 1977<br />
to 1987, and who sadly died in July<br />
<strong>2005</strong>. Tony Swerdlow, Chairman of<br />
the Section of Epidemiology, led a<br />

REVIEW OF <strong>2005</strong><br />
major international collaboration to<br />
investigate whether mobile phone use<br />
increases the risk of brain tumours.<br />
<strong>The</strong> conclusion was that it does not.<br />
Such studies must be revisited and<br />
updated but they are of great value<br />
in allowing individuals to rationally<br />
evaluate the risks that they face.<br />
More accurate, and earlier, diagnosis<br />
of cancer remains a major priority,<br />
and this is particularly important for<br />
prostate cancer because we need to be<br />
able to identify those men to whom it<br />
is an immediate threat, so that they<br />
can be treated, and those who will<br />
live a normal life for many years,<br />
requiring only careful monitoring.<br />
Colin Cooper, Chairman of the<br />
Section of Molecular Carcinogenesis,<br />
has continued his important work to<br />
identify markers which allow this<br />
distinction to be made, and has added<br />
HOXB13 to the list of such markers<br />
that merit detailed clinical evaluation.<br />
He has also made a very important<br />
technical contribution by developing<br />
a method for making tissue arrays<br />
from prostate needle biopsies. <strong>The</strong><br />
rather simple device that has been<br />
developed will make it enormously<br />
easier to use large numbers of the<br />
newly developed markers to build<br />
up a comprehensive assessment<br />
of the likelihood that the disease<br />
will progress.<br />
It is now clear that screening the<br />
population for some cancers, for<br />
example breast and cervical, can be<br />
highly beneficial and it is therefore<br />
important to develop more accurate<br />
and sensitive screening procedures.<br />
Women who carry mutations in<br />
BRCA1 or BRCA2 are at extremely<br />
high risk of contracting breast, and<br />
ovarian, cancer at a young age.<br />
Conventional, mammographic,<br />
screening procedures do not work so<br />
well on younger women because their<br />
breasts are dense, so there is a clear<br />
need for an alternative method.<br />
Martin Leach, Co-Director of the<br />
Cancer <strong>Research</strong> UK Clinical Magnetic<br />
Resonance <strong>Research</strong> Group, led a<br />
major national trial, funded by the<br />
Medical <strong>Research</strong> Council, to explore<br />
the use of magnetic resonance<br />
imaging (MRI) for this purpose. <strong>The</strong><br />
MARIBS trial showed that MRI is<br />
much more effective in such younger<br />
women and it is to be hoped that<br />
this new screening modality will<br />
become widely available to women<br />
at high risk.<br />
<strong>2005</strong> was a landmark year for results<br />
from clinical trials of targeted<br />
biological therapies in solid cancers<br />
which will change clinical practice,<br />
and senior researchers from the <strong>Royal</strong><br />
<strong>Marsden</strong> and <strong>The</strong> Institute played a<br />
significant part in three key<br />
developments. Sorafenib was<br />
originally developed for its ability<br />
to inhibit C-RAF, but it has multiple<br />
targets including the vascular<br />
endothelial growth factor receptor<br />
(VEGFR). Tim Eisen and Martin Gore<br />
from the Renal Unit conducted a<br />
randomised trial in conjunction with<br />
US colleagues which showed that the<br />
drug was effective as second line<br />
therapy, and this was subsequently<br />
confirmed in a larger multi-centre<br />
international trial. In December <strong>2005</strong><br />
Sorafenib received a license for<br />
advanced renal cell cancer based on<br />
the data generated from these two<br />
studies in which <strong>The</strong> Institute and<br />
<strong>Royal</strong> <strong>Marsden</strong> played a major role.<br />
David Cunningham from the GI Unit<br />
led a randomised international trial of<br />
the monoclonal antibody cetuximab<br />
targeted against the epidermal growth<br />
factor receptor (EGFR) which is overexpressed<br />
in 60-80% of colorectal<br />
cancers. <strong>The</strong> results showed that the<br />
addition of cetuximab to irinotecan<br />
chemotherapy improved tumour<br />
response rates and time to disease<br />
progression compared with cetuximab<br />
alone, leading to this new treatment<br />
being licensed for irinotecanrefractory<br />
metastatic colorectal cancer.<br />
At the American Society of Clinical<br />
Oncology meeting in June <strong>2005</strong><br />
dramatic results were announced from<br />
three pivotal international trials of the<br />
monoclonal antibody trastuzumab<br />
(Herceptin) which targets the growth<br />
factor receptor HER2 that is overexpressed<br />
in 20% of breast cancers.<br />
<strong>The</strong>se trials showed that the addition<br />
of Herceptin to chemotherapy for<br />
early breast cancer reduced the rate of<br />
recurrence by 50%, representing the<br />
single biggest improvement in<br />
outcome ever seen for any adjuvant<br />
drug therapy in breast cancer. Ian<br />
Smith from the Breast Unit led the<br />
UK’s involvement in the HERA trial<br />
through <strong>The</strong> Institute's Clinical Trials<br />
Unit.<br />
Radiotherapy research has focussed<br />
on the development of new<br />
techniques that can then be adopted<br />
more widely in the NHS. In prostate<br />
9
REVIEW OF <strong>2005</strong><br />
cancer, the Urology Unit has<br />
continued its work in conformal<br />
radiotherapy with the introduction<br />
of a quality assurance programme<br />
that has now allowed the technique<br />
to be taken up by 50% of the UK’s<br />
radiotherapy units. A similar<br />
approach is now underway with<br />
intensity modulated radiotherapy,<br />
and the current CHHIP trial that<br />
was started at the <strong>Royal</strong> <strong>Marsden</strong> by<br />
David Dearnaley has now expanded<br />
to ten other UK centres. This study<br />
explores the use of shorter hypofractionated<br />
radiotherapy courses<br />
which if successful would mean<br />
a much better utilisation of scarce<br />
radiotherapy resources. On behalf<br />
of the Breast Unit John Yarnold<br />
presented the final 5-year results of<br />
the RMH Breast Radiotherapy<br />
Dosimetry Trial in October <strong>2005</strong>,<br />
which confirm that 3D intensity<br />
modulated radiotherapy reduces the<br />
risk and severity of late radiotherapy<br />
adverse effects in the breast. <strong>The</strong>se are<br />
the first randomised data relating to<br />
this technique of breast radiotherapy<br />
(developed at <strong>The</strong> Institute and the<br />
<strong>Royal</strong> <strong>Marsden</strong> in the late 1990s) and<br />
underpin the introduction of this<br />
technique UK-wide.<br />

their achievements<br />
<strong>The</strong> Chairmen and the Chief Executive<br />
of <strong>The</strong> Institute offer their warmest<br />
congratulations to Cally Palmer, the<br />
Chief Executive of the <strong>Royal</strong> <strong>Marsden</strong>,<br />
who was awarded the CBE in the New<br />
Year Honours List for services to the<br />
NHS. This is an enormously well<br />
deserved recognition of her<br />
outstanding contributions to the<br />
treatment and care of cancer patients,<br />
and to research and education.<br />
We were all absolutely delighted that<br />
David Barford, Professor of Molecular<br />
Biology and Co-Chairman of the<br />
Section of Structural Biology, was<br />
elected to the Fellowship of the <strong>Royal</strong><br />
Society. This is the highest honour in<br />
the British scientific system and is a<br />
great tribute to his outstanding<br />
research into the mechanisms which<br />
control the growth of cells. It is<br />
failures in these mechanisms which<br />
underlie cancer and Professor Barford's<br />
work has greatly influenced the<br />
development of new anticancer drugs.<br />
Alan Horwich, Chairman of the<br />
Section of Radiotherapy, stood down<br />
as Director of Clinical <strong>Research</strong> and<br />
Development for the <strong>Royal</strong> <strong>Marsden</strong><br />
and <strong>The</strong> Institute at the end of<br />
September, consequent upon his<br />
appointment as Academic Dean of<br />
<strong>The</strong> Institute. He had undertaken this<br />
role with great distinction for eleven<br />
years, and was instrumental in<br />
maintaining the Trust’s income from<br />
NHS R&D. He is succeeded by<br />
Stephen Johnston, Consultant<br />
Medical Oncologist for the Breast<br />
Unit, to whom we wish every success.<br />
He faces new challenges as we seek to<br />
respond effectively to the Department<br />
of Health’s new <strong>Research</strong> Strategy.<br />
Janet Husband, Professor of<br />
Radiology, has been elected Vice-Chair<br />
of the Academy of Medical <strong>Royal</strong><br />
Colleges, and was awarded the Gold<br />
Medal of the European Association<br />
of Radiology. Ian Judson, Professor<br />
of Clinical Pharmacology and Head<br />
of the Sarcoma Unit, has been elected<br />
President of the British Sarcoma Group.<br />

separately recorded in our respective<br />
<strong>Annual</strong> <strong>Report</strong>s and Accounts. In the<br />
financial year ending on 31 March<br />
2006, the Trust met its key financial<br />
objectives and achieved a budgeted<br />
surplus. In the financial year ending<br />
on 31 July <strong>2005</strong>, <strong>The</strong> Institute<br />
achieved a balanced budget on<br />
unrestricted funds after transfers. Its<br />
expenditure on research grew by<br />
11.1% from the previous year, with<br />
increases in spending across a number<br />
of Sections.<br />
Overall, the combined annual<br />
turnover of our organisation<br />
was £230 million, with 91% of<br />
this total being devoted to<br />
research activities and patient<br />
care services.<br />
Government funding for our joint<br />
research activities contributes 38%<br />
of the total resources for research.<br />
Our success rate in competing<br />
for research funding from external<br />
sources continues to be outstanding,<br />
at 77% of all applications for peerreviewed<br />
grants to medical charities<br />

Many organisations also contribute<br />
support by providing funds for<br />
studentships at <strong>The</strong> Institute and<br />
clinical fellowships at the hospital.<br />
<strong>The</strong> <strong>Royal</strong> <strong>Marsden</strong> and <strong>The</strong> Institute<br />
are grateful to all the numerous<br />
organisations and supporters who<br />
have made investments in our<br />
research activities.<br />
Fundraising<br />
<strong>The</strong> Institute is extremely grateful to<br />
all its supporters for joining us in the<br />
fight against cancer. It is only with this<br />
support that we can hope to achieve<br />
our objective that one day people will<br />
be able to live free from the fear of<br />
cancer as a life threatening disease.<br />
Our Everyman Male Cancer Campaign<br />
continues to gain momentum through<br />
the media and our wide range of<br />
corporate partnerships. High profile<br />
supporters included Topman, Tesco,<br />
Cosmopolitan Magazine, <strong>The</strong> Football<br />
Association and Professional<br />
Footballers’ Association amongst<br />
others, plus we have seen continued<br />
success with our annual fundraising<br />
initiative TacheBack, now in its third<br />
year. We would like to thank all those<br />
who have contributed to our<br />
continuing success, including Rotary<br />
International in Great Britain and<br />
Ireland, <strong>The</strong> Grand Charity of<br />
Freemasons, <strong>The</strong> Clothworkers’<br />
Foundation, Will for Free law firms<br />
and the many friends and individuals<br />
who have supported our work through<br />
donations, the organisation of events,<br />
or attendance at fundraising occasions.<br />
We continue to be one of the most<br />
cost-effective cancer research<br />
organisations in the world with over<br />
90% of our total income going directly<br />
into research.<br />
In February 2006, the <strong>Royal</strong> <strong>Marsden</strong><br />
Cancer Campaign reached its £30<br />
million Make Our Day appeal target,<br />
for six major projects within the<br />
hospital. Of these, four had already<br />
been achieved; a specialist Critical<br />
Care Unit, a combined PET/CT<br />
scanner, the Oak Foundation Drug<br />
Development Unit, and a Medical Day<br />
Unit. New operating theatres are under<br />
construction and a Diagnostic Centre<br />
for the Chelsea site is in the planning<br />
stages. Many generous gifts from<br />
major benefactors, trusts and<br />
companies were augmented by the<br />
efforts of volunteer fundraisers and<br />
the families and friends of patients<br />
and their well-wishers, as well as the<br />
hospital's staff and the general public.<br />
We are immensely grateful to all those<br />
who have contributed to the success<br />
of the Make Our Day appeal. Support<br />
for the general charitable funds of<br />
the hospital, including the purposes<br />
of research, and staff and patient<br />
amenities, continues to be actively<br />
sought and carefully distributed.<br />
New major appeal projects are in the<br />
planning stage.<br />
It is a great pleasure to present this,<br />
our joint <strong>Annual</strong> <strong>Research</strong> <strong>Report</strong> for<br />
<strong>2005</strong>. We pay tribute to everyone who<br />
has contributed to our achievements<br />
this year, not least our outstanding<br />
scientists and clinicians whose<br />
excellence and dedication keep <strong>The</strong><br />
<strong>Royal</strong> <strong>Marsden</strong> NHS Foundation Trust<br />

<strong>The</strong> Faculty, Teachers<br />
and Awards<br />
<strong>The</strong> achievements of our senior<br />
scientists and clinicians continue to<br />
be recognised by the conferment<br />
of academic titles of the University<br />
of London. <strong>The</strong> title of Professor<br />
of Molecular and Population Genetics<br />
was conferred upon Richard Houlston<br />
and the title of Reader in Cell Biology<br />
was conferred upon Pascal Meier.<br />
Nazneen Rahman was appointed to<br />
the established chair of Childhood<br />
Cancer Genetics. Dr Tim Eisen,<br />
Dr Richard Lamb and Dr Eric So were<br />
granted recognition as Teachers<br />
of the University of London. <strong>The</strong><br />
title of Emeritus Professor was<br />
conferred upon the former Academic<br />
Dean, Professor Bob Ott.<br />
Conferences, lectures<br />
and seminars<br />
A highlight of <strong>The</strong> Institute’s<br />
academic year is the annual Institute<br />
Conference, an event which aims to<br />
share knowledge and expertise across<br />
<strong>The</strong> Institute and <strong>Royal</strong> <strong>Marsden</strong><br />
NHS Foundation Trust, and to<br />
encourage collaboration in research.<br />
Staff and students contribute in<br />
a variety of ways, and the blend of<br />
lectures, student presentations, and<br />
team poster presentations, display<br />
the breadth of research in <strong>The</strong><br />
Institute and the <strong>Royal</strong> <strong>Marsden</strong>.<br />
<strong>The</strong> sessions of this year’s Institute<br />
Conference, held at the University<br />
of Surrey, were entitled: A Crossover<br />
Tour of Physics and Biology<br />
(Chair: Dr Kathy Weston); Chemistry<br />
(Chair: Dr Ted McDonald);<br />
Clinical Session (Chair: Professor Bob<br />
Ott); Epidemiology and Clinical<br />
Trials (Chairs: Professor Tony<br />
Swerdlow and Professor Judith Bliss);<br />
Late Breaking Publications (Chair:<br />
Professor Keith Willison); and finally<br />
Structural Biology (Chair: Professor<br />
Laurence Pearl). A new addition this<br />
year was two workshop sessions<br />
chaired by Dr Jeff Bamber and Dr<br />
Pascal Meier.<br />
Student oral presentations were<br />
chosen by submission of abstracts and<br />
were of customary high quality. <strong>The</strong><br />
Third Year student poster prizewinner<br />
was Giorgia Vicentini, with Katrin<br />
Gudmundsdottir and David Mason<br />
as runners-up.<br />
<strong>The</strong> Institute’s Distinguished<br />
Lecture Series continues to attract<br />
outstanding scientists of international<br />
renown. Notable lectures this year<br />
included: ‘From embryonic stem cells<br />
to neural stem cells’ (Professor Austin<br />
Smith, <strong>The</strong> Institute for Stem Cell<br />
<strong>Research</strong>, University of Edinburgh);<br />
‘Invasive growth: A genetic program<br />
linking coagulation to metastasis’<br />
(Professor Paolo M Comoglio,<br />
Institute for Cancer <strong>Research</strong>, Torino,<br />
Italy); ‘Mouse models for cancer’<br />
(Dr Anton Berns, Division of<br />
Molecular Genetics and Center of<br />
Biomedical Genetics, <strong>The</strong> Netherlands<br />

<strong>The</strong> Netherlands Cancer Institute,<br />
Amsterdam); and ‘Regulating<br />
craniofacial and bone development’<br />
(Dr Robb Krumlauf, Stowers<br />
Institute for Medical <strong>Research</strong>,<br />
Kansas City, USA).<br />
This year’s Link Lecture, which took<br />
place in September, was given by Dr<br />
Sanjiv Sam Gambhir of the Department<br />
of Radiology at Stanford University and<br />
was entitled ‘Seeing is believing:<br />
Molecular imaging in living subjects’.<br />
<strong>The</strong> Inter-site Lecture Series, designed<br />
to foster greater links between the<br />
Chelsea and Sutton campuses, continues<br />
to go from strength to strength. <strong>The</strong>se<br />
complement the large numbers of<br />
seminars with external speakers that are<br />
organised by individual Sections.<br />
<strong>The</strong> Graduate School<br />
A major strategic development in<br />
<strong>2005</strong> was the institution of the<br />
Graduate School, established as a<br />
Corporate Services department<br />
bringing together the Registry, the<br />
Interactive Education Unit, and<br />
the Library and Information Service<br />
into one integrated academic support<br />
service. A new Registrar and Director<br />
of <strong>The</strong> Graduate School, Mr Simon<br />
Hobson, was appointed at the end of<br />
September. <strong>The</strong> Graduate School is<br />
based in the Sir Richard Doll Building<br />
at <strong>The</strong> Institute’s Sutton campus that<br />
became operational in October.<br />
In parallel with the creation of the<br />
Graduate School, the arrangements<br />
for the academic management of<br />
our substantive research degree<br />
programme were also reviewed and<br />
an Academic Dean’s Team has been<br />
established in order to formalise the<br />
existing processes. <strong>The</strong> Team meets<br />
on a monthly basis and, in addition<br />
to the Academic Dean, comprises<br />
the following members of <strong>The</strong><br />
Institute’s Faculty: Professor Ann<br />
Jackman, Deputy Dean (Biomedical<br />
Sciences); Professor Kathy Pritchard-<br />
Jones, Deputy Dean (Clinical<br />
Sciences); Dr Jeff Bamber, Senior<br />
Tutor (Sutton); and Dr Kathy<br />
Weston, Senior Tutor (Chelsea).<br />
Our research degree programme has<br />
in excess of 100 research degree<br />
students working on cancer-related<br />
projects and enrolled on MPhil or<br />
PhD degrees of the University of<br />
London. Demand for entry to our<br />
PhD research training programme<br />
remained very high with many<br />
outstanding students from the UK<br />
and overseas being keen to join<br />
us. <strong>The</strong>re were 395 applications with<br />
23 new MPhil/PhD students joining<br />
in September <strong>2005</strong>, including four<br />
clinical fellows. We have 6 part-time<br />
MPhil/PhD registrations. In addition<br />
to those following MPhil and PhD<br />
degrees, there were a smaller number<br />
of clinical research students following<br />
a two-year part-time Advanced<br />
Degree in Medicine of the University<br />
of London, the Doctor of Medicine<br />
(MD). <strong>The</strong> MD was recently reviewed<br />
by the University of London and<br />
from 1 September <strong>2005</strong> the revised<br />
title of MD(Res) was instituted. 30<br />
students were registered for the MD<br />
or MD(Res) at the end of <strong>2005</strong>.<br />
As always we acknowledge and<br />
thank those organisations that have<br />
supported our students during the<br />
past year: AstraZeneca, Breakthrough<br />
Breast Cancer, Cancer <strong>Research</strong><br />
UK, the Engineering and Physical<br />
Sciences <strong>Research</strong> Council,<br />
the Medical <strong>Research</strong> Council<br />
and Leukaemia <strong>Research</strong>.<br />
<strong>The</strong> Award Ceremony took place<br />
on 28 April in the Brookes Lawley<br />
Building, Sutton and was attended<br />
by Professor Sir Graeme Davies,<br />
Vice-Chancellor of the University<br />
of London. In total 40 graduands<br />
received their University of London<br />
degrees, and of those 32 gained the<br />
Doctor of Philosophy (PhD); 2 gained<br />
the Master of Philosophy (MPhil) and<br />
6 received the Doctor of Medicine<br />
(MD). <strong>The</strong> Chairman’s Prize for the<br />
best graduating PhD students<br />
was awarded to Dr Geoffrey Charles-<br />
Edwards and Dr Mathew Garnett.<br />

<strong>The</strong>re were also five conferrals of<br />
‘Member of <strong>The</strong> Institute’ and<br />
nine of ‘Associate of <strong>The</strong> Institute’.<br />
New taught<br />
postgraduate course<br />
Whilst <strong>The</strong> Institute’s primary<br />
educational activity concerns<br />
research, in order to deliver our<br />
mission we also need to place<br />
importance on postgraduate teaching.<br />
<strong>The</strong>refore a major academic<br />
development this year - that came<br />
to fruition when the first students<br />
commenced their studies in March<br />
2006 - was the policy decision to<br />
develop a taught postgraduate<br />
qualification in Oncology. This is<br />
the first of a possible portfolio of<br />
courses aimed at educating and<br />
training the next generation of<br />
specialist cancer clinicians. A<br />
validation event was held in<br />
December <strong>2005</strong> which subjected the<br />
proposals to intensive peer review<br />
and resulted in a recommendation to<br />
the Academic Board that the course<br />
be approved.<br />
<strong>The</strong> course adopts a modular, credit<br />
accumulation model that will be<br />
attuned to the specific needs of the<br />
students. Individual 5 or 10 credit<br />
modules will be designed to provide<br />
detailed and distinct skills, together<br />
with advanced knowledge in a<br />
particular aspect of Oncology. Taken<br />
together in defined blocks of 60<br />
and 120 credits, these credit-bearing<br />
modules will lead to a coherent<br />
part-time programme with possible<br />
exit points at Postgraduate Certificate<br />
and Diploma level. <strong>The</strong> final<br />
research phase, which will require<br />
the submission of a 20,000 word<br />
dissertation, or the equivalent<br />
presentation of scientific papers for<br />
assessment, will lead to the MSc<br />
Degree level award.<br />
We have identified a strong market<br />
demand for this course which comes<br />
from UK-based students who are<br />
working as Specialist Registrars in<br />
medical specialties following training<br />
schemes managed by their local<br />
NHS Deaneries. In the field of<br />
clinical oncology, a structured<br />
training programme is necessary<br />
for entitlement to sit the Part 1 and<br />
Part 2 examinations for Fellowship<br />
of the <strong>Royal</strong> College of Radiologists<br />
(FRCR). <strong>The</strong> Institute’s course will<br />
deliver - in 120 ‘M’ level credits -<br />
the core curriculum necessary to<br />
sit these examinations and it is<br />
expected that all the Clinical<br />
Oncologists will do so. For Medical<br />
Oncologists, this course will meet the<br />
perceived need for an improvement<br />
in the theoretical basis of their<br />
structured training.<br />
In overall terms the course has<br />
been designed to exploit the existing<br />
academic profile, specialist facilities,<br />
research-intensive learning<br />
environment, and world-class<br />
academic and administrative staff<br />
resources at <strong>The</strong> Institute. It will<br />
exploit the latest educational tools<br />
and techniques to deliver a high<br />
quality, cutting-edge modular taught<br />
postgraduate course for specialists<br />
in the field of Clinical and<br />
Medical Oncology.<br />
<strong>The</strong> course will be based at the<br />
Chester Beatty Laboratories, Chelsea<br />
and will be led by two <strong>Joint</strong><br />
Course Leaders, Dr Robert Huddart<br />
(Department of Radiotherapy) and<br />
Dr David Bloomfield (Brighton and<br />
Sussex University Hospitals NHS Trust).<br />
Visitors<br />
<strong>The</strong> Institute hosted a typically<br />
large number of visitors in its<br />
laboratories during <strong>2005</strong>. We are<br />
fortunate in having the resources<br />
of the Haddow Fund with which<br />
to foster important links with the<br />
international scientific community<br />
attracted by the excellence of <strong>The</strong><br />
Institute. This year the Haddow Fund<br />
supported visits from Dr Annette<br />
Affolter to work with Dr Richard<br />
Marais, Dr Konstantin Lavrenkov<br />

<strong>The</strong> Interactive Education Unit<br />
(IEU) was established at <strong>The</strong> Institute<br />
in 1999 with the remit to develop<br />
Web- and CD ROM-based educational<br />
resources (www.ieu.icr.ac.uk).<br />
<strong>The</strong> overarching aim of the IEU is<br />
to promote and disseminate the<br />
educational, research and clinical<br />
activities of <strong>The</strong> Institute in order<br />
to improve the treatment, care and<br />
quality of life of people with cancer.<br />
<strong>The</strong> Unit has won a number of<br />
awards, including a Platinum award<br />
(the highest accolade) for its website<br />
in the MarCom creative awards,<br />
a leading international marketing<br />
and communications competition.<br />
IEU projects are developed in<br />
collaboration with leading scientists<br />
and clinicians at both <strong>The</strong> Institute<br />
and the <strong>Royal</strong> <strong>Marsden</strong>. <strong>The</strong> Unit has<br />
three key audiences: scientists and<br />
students, healthcare professionals,<br />
and patients and the public.<br />
Examples of projects in each of these<br />
categories are detailed below.<br />

Scientists and students –<br />
developing resources to aid<br />
research/career development<br />
• <strong>The</strong> Study Skills Website was launched<br />
in July 2002 on <strong>The</strong> Institute’s<br />
intranet. It aims to provide students<br />
with a range of transferable skills<br />
such as time management and<br />
communication. <strong>The</strong> website is part<br />
of <strong>The</strong> Institute’s strategy to meet<br />
the skills training requirements for<br />
PhD students funded by the <strong>Research</strong><br />
Councils. Sections on intellectual<br />
property and critical reading were<br />
added to the site in June <strong>2005</strong>.<br />
• Study Skills: A Student Survival Guide<br />
(see Figure 1) was published in March<br />
<strong>2005</strong>. Content from the Study Skills<br />
Website was adapted and expanded<br />
into an informative and user-friendly<br />
handbook, published by John Wiley<br />
& Sons. It identifies the transferable<br />
skills research students need to<br />
progress successfully through their<br />
PhD and on into their working lives.<br />
<strong>The</strong> book is an invaluable aid to<br />
science-based PhD students across<br />
the UK.<br />
• Perspectives in Oncology – the cancer<br />
science website (see Figure 2a) was<br />
launched in June 2004 to provide<br />
students at <strong>The</strong> Institute with a<br />
thorough and connected grounding<br />
in the field of cancer science. <strong>The</strong><br />
site emphasises how discoveries in<br />
scientific research translate into<br />
clinical care and highlights how the<br />
fields of physics, biology, chemistry<br />
and medicine all contribute to<br />
understanding, managing and<br />
treating cancer. <strong>The</strong> site was<br />
launched initially with five modules,<br />
covering causes and prevention<br />
of cancer, common cancers,<br />
therapies, genetics of cancer,<br />
and bioinformatics. A module on<br />
medical physics was added in July<br />
<strong>2005</strong>, with a further four modules<br />
scheduled to be launched and<br />
developed in 2006-7.<br />

TECHNOLOGY TRANSFER<br />
REPORT <strong>2005</strong><br />
<strong>The</strong> Institute and <strong>Royal</strong> <strong>Marsden</strong> work with commercial partners so that research findings<br />
can be developed and manufactured for the benefit of patients worldwide. <strong>The</strong> Director of<br />
Enterprise outlines the highlights of this technology transfer activity during <strong>2005</strong>.<br />
Susan Bright<br />
PhD<br />
Susan Bright is Director<br />
of Enterprise at <strong>The</strong> Institute<br />
of Cancer <strong>Research</strong><br />
<strong>The</strong> Enterprise Unit at <strong>The</strong> Institute,<br />
working together with the <strong>Royal</strong><br />
<strong>Marsden</strong>, has again had a very active<br />
and successful year.<br />
<strong>The</strong> objective of the Enterprise Unit<br />
is to facilitate the transfer of research<br />
outputs to commercial organisations<br />
that can provide development<br />
resources. Inventions are thereby<br />
disseminated to as wide a patient base<br />
as possible. This technology transfer<br />
effort focuses primarily on ensuring<br />
that the route of development chosen<br />
is capable of delivering maximum<br />
patient benefit.<br />
Return of revenue to <strong>The</strong> Institute<br />
and the <strong>Royal</strong> <strong>Marsden</strong> is a welcome<br />
additional result of the work of the<br />
Enterprise Unit. <strong>The</strong> Unit continues<br />
to work in partnership with Cancer<br />
<strong>Research</strong> Technology Ltd (CRT) who<br />
take the lead in the commercial<br />
exploitation of Cancer <strong>Research</strong> UK<br />
funded work. <strong>The</strong> Unit also works<br />
closely with British Technology<br />
Group (BTG), the Wellcome Trust and<br />
other technology transfer<br />
organisations as appropriate to<br />
specific projects.<br />
Astex Ltd (PKB collaboration)<br />
In 2003 <strong>The</strong> Institute began a<br />
collaboration with the drug discovery<br />
company Astex on the development<br />
of novel inhibitors of the enzyme<br />
protein kinase B (PKB). It is<br />
anticipated that these inhibitors will<br />
be useful anticancer drugs. Professors<br />
David Barford and Paul Workman are<br />
<strong>The</strong> Institute project leaders for this<br />
collaboration. <strong>The</strong> project has been<br />
successful and several promising drug<br />
candidates have been identified. In<br />
<strong>2005</strong> Astex secured a licensing<br />
agreement with AstraZeneca for this<br />
project. This means that these novel<br />
anticancer drugs will now be<br />
developed further by a large<br />
pharmaceutical company,<br />
demonstrating the value of the initial<br />
research programme.<br />
PETRRA Ltd<br />
<strong>The</strong> Institute continues its active<br />
involvement in the spin-out company<br />
PETRRA, which was founded to<br />
develop the novel positron emission<br />
tomography (PET) camera invented<br />
by <strong>The</strong> Institute, the <strong>Royal</strong> <strong>Marsden</strong><br />
and the Rutherford Appleton<br />
Laboratory, based on the research of<br />
Professor Bob Ott. <strong>The</strong> first clinical<br />
trial of the camera was successfully<br />
completed in 2004. In <strong>2005</strong> PETRRA<br />
completed an investment agreement<br />
with the Rainbow Seed Fund, thus<br />

Domainex Ltd<br />
In 2002 <strong>The</strong> Institute played a key<br />
role in establishing the new spin-out<br />
company Domainex together with its<br />
partners, UCL and Birkbeck.<br />
17
TECHNOLOGY TRANSFER REPORT <strong>2005</strong><br />
Domainex secured investment from<br />
the Bloomsbury Bioseed Fund.<br />
Professor Laurence Pearl and Dr Chris<br />
Prodromou were <strong>The</strong> Institute’s<br />
founder scientists. Domainex was<br />
established to exploit a novel<br />
technology that enables rapid analysis<br />
of the structure and function of<br />
complex proteins and which can be<br />
applied to a wide range of oncology<br />
targets. In <strong>2005</strong> Domainex secured a<br />
second commercial contract and has<br />
made considerable progress in<br />
developing the technology.<br />
Chroma <strong>The</strong>rapeutics Ltd<br />
<strong>The</strong> Institute continues its active<br />
involvement in Chroma <strong>The</strong>rapeutics<br />
which is a spin-out company based<br />
on work carried out at the University<br />
of Cambridge and by Professor Paul<br />
Workman at <strong>The</strong> Institute. Chroma<br />
was founded to develop novel<br />
anticancer drugs directed against<br />
enzymes involved in the remodelling<br />
of chromatin. In <strong>2005</strong> Chroma made<br />
good scientific progress in several key<br />
programmes. One project,<br />
investigating the enzyme Aurora A,<br />
involves an active collaboration with<br />
Institute scientists including a team<br />
in the Breakthrough Breast Cancer<br />
<strong>Research</strong> Centre. Chroma is now<br />
based in Oxford, has nearly 50<br />
employees and is financially sound.<br />
PIramed Ltd<br />
In 2003 the company PIramed was<br />
founded, based on research arising<br />
from the Ludwig Institute of Cancer<br />
<strong>Research</strong>, Cancer <strong>Research</strong> UK and<br />
Professor Paul Workman at <strong>The</strong><br />
Institute. PIramed is developing a<br />
number of drug products principally<br />
focused on inhibitors of the PI3<br />
kinase superfamily. In <strong>2005</strong> PIramed<br />
successfully secured a licensing deal<br />
with the US company Genentech for<br />
its lead series of novel drug<br />
candidates. <strong>The</strong> Institute was<br />
instrumental in developing this series.<br />
PIramed has successfully raised<br />
investment finance on more than one<br />
occasion and is now based in Slough<br />
with over 30 employees.<br />
Vernalis Ltd (HSP90<br />
collaboration)<br />
In 2002 <strong>The</strong> Institute began a<br />
collaboration with the Cambridge<br />
based biotechnology company<br />
RiboTargets (now Vernalis) to develop<br />
inhibitors of the molecular chaperone<br />
HSP90, which plays an important role<br />
in directing the function of many key<br />
intracellular ‘oncogenic’ proteins.<br />
Inhibitors of HSP90 can thus affect<br />
the function of these proteins,<br />
leading to an anticancer effect. <strong>The</strong><br />
HSP90 project combined the<br />
resources and skills of both Vernalis<br />
and <strong>The</strong> Institute; the lead Institute<br />
scientists on this programme were<br />
Professors Laurence Pearl and Paul<br />
Workman. <strong>The</strong> collaboration ended<br />
its first phase in 2004 having<br />
successfully developed several novel,<br />
potent HSP90 inhibitors and Vernalis<br />
secured a licensing agreement with<br />
Novartis who will take these<br />
compounds into the clinic. In <strong>2005</strong><br />
Novartis announced that one of the<br />
lead compounds had met the criteria<br />
to be selected as a preclinical<br />
development candidate.<br />
BRAF collaboration with the<br />
Wellcome Trust<br />
In 2002 <strong>The</strong> Institute began a<br />
collaboration with the Wellcome<br />
Trust and Cancer <strong>Research</strong> UK to<br />
develop novel drugs to inhibit the<br />
protein BRAF. <strong>The</strong> identification of<br />
BRAF as a cancer target resulted from<br />
<strong>The</strong> Institute’s involvement with the<br />
Wellcome funded Cancer Genome<br />
Project. <strong>The</strong> joint venture is managed<br />
by Institute scientists, the Enterprise<br />
Unit, CRT and the Wellcome Trust. In<br />
addition the company Astex joined<br />
the collaboration in 2004, which is<br />
being project managed by Dr Richard<br />
Marais from <strong>The</strong> Institute. <strong>The</strong><br />
18
TECHNOLOGY TRANSFER REPORT <strong>2005</strong><br />
collaboration has identified two<br />
distinct chemical series of promising<br />
novel BRAF inhibitors. In <strong>2005</strong> the<br />
science continued to progress well<br />
and one series of compounds is<br />
showing great potential. <strong>The</strong><br />
Wellcome Trust is leading the<br />
commercialisation effort and is<br />
actively negotiating with a number of<br />
pharmaceutical companies about<br />
partnering this project.<br />
Quinazolines (BTG<br />
collaboration)<br />
Professor Ann Jackman has worked<br />
for a number of years on novel<br />
quinazoline anticancer drugs. Her<br />
first success in this area was<br />
the compound Tomudex which is<br />
now on the market and earning<br />
royalties. Other quinazoline drugs<br />
with different mechanisms of<br />
action are in development, all in<br />
partnership with BTG. One of<br />
these drugs, the compound BGC<br />
9331, is successfully going<br />
through a Phase II clinical trial and<br />
evidence of efficacy has been seen.<br />

Professor Martin Leach’s team has<br />
developed a number of novel tools to<br />
help in expanding the role of<br />
magnetic resonance imaging and<br />
spectroscopy in both a diagnostic and<br />
treatment setting. Several patents<br />
have been filed and there are also a<br />
number of items of proprietary<br />
software, including a novel<br />
workstation for computer-assisted<br />
diagnosis of breast cancer (MRIBview;<br />

Survival in children with cancer<br />
has progressively improved over the<br />
last three decades, so that currently<br />
75% of patients are cured and are<br />
long-term survivors (see Figure 1).<br />
<strong>The</strong> survival of children with<br />
hepatoblastoma (a liver tumour),<br />
for example, has increased from 40 to<br />
80%. This improvement has been due<br />
to international multidisciplinary<br />
trials which are designed, executed<br />
and analysed by well established<br />
co-operative groups.<br />
<strong>The</strong> United Kingdom<br />
Children’s Cancer Study Group<br />
(UKCCSG) is one of the world’s<br />
leading children’s cancer trial<br />
groups.<br />
Despite these advances, childhood<br />
cancers are still the principal cause of<br />
death from disease between infancy<br />
and adulthood in developed<br />
countries; one in four children do<br />
not survive their illness. Furthermore,<br />

even when cancer treatment is<br />
successful, there can be significant<br />
side-effects ranging from second<br />
cancers (caused as a result of the<br />
treatment) to infertility.<br />
To improve further survival in<br />
childhood malignancy it is necessary:<br />
• To make additional improvements<br />
through clinical trials. Most<br />
clinical trials in children’s<br />
malignancy are already carried<br />
out on an international, mostly<br />
European, basis. <strong>The</strong> goal is for<br />
all children with malignancy<br />
to be entered into randomised<br />
clinical trials. To achieve this,<br />
further collaboration, especially<br />
with North America, is being<br />
developed so that for rare childhood<br />
malignancies there are joint<br />
international trials. For the<br />
more common malignancies,<br />
complementary randomised<br />
trials can be developed.<br />
• To understand in greater detail<br />
the underlying biology of childhood<br />
malignancy.<br />
• To develop new anticancer agents<br />
which specifically target the genetic<br />
abnormalities that cause childhood<br />
and young people’s malignancies.<br />
<strong>The</strong> joint vision of <strong>The</strong> Institute<br />
and <strong>Royal</strong> <strong>Marsden</strong> is to<br />
improve survival for the 25%<br />
of children with cancer who at<br />
present die from their disease,<br />
through the development of<br />
new anticancer agents which<br />
specifically target the genetic<br />
abnormalities that cause<br />
childhood and young<br />
people’s malignancies.<br />
<strong>The</strong> Paediatric and<br />
Adolescent Oncology<br />
Targeted Drug<br />
Development Programme<br />
<strong>The</strong>me and aims<br />
Cancer in children and young<br />
people is different in its biological<br />
basis from adult malignancy.<br />
At present, children with cancer are<br />
treated with drugs that have been<br />
adapted from compounds developed<br />
to treat adult cancers. To date, no<br />
drugs have been made specifically to<br />
treat childhood cancers and<br />
internationally there is no centre<br />
which has a major programme and<br />
facilities in this area.<br />
<strong>The</strong> Paediatric and Adolescent<br />
Oncology Targeted Drug<br />
Development Programme at <strong>The</strong><br />
Institute / <strong>Royal</strong> <strong>Marsden</strong> has<br />
been created to fulfil the<br />
international unmet need in drug<br />
discovery for children with cancer.<br />
A central theme of the programme is<br />
the ‘bench to bedside’ translation<br />
of laboratory research to clinical<br />
trials which will ultimately alter<br />
international practice in paediatric<br />
oncology. <strong>The</strong> programme comprises<br />
target identification, drug discovery,<br />
preclinical evaluation, preclinical<br />
and early clinical functional imaging,<br />
and clinical trials. It is envisaged<br />
that the programme will further<br />
improve survival of children and<br />
young people with cancer.<br />
<strong>The</strong> Paediatric and Adolescent<br />
Oncology Targeted Drug<br />
Development Programme<br />
is a comprehensive approach<br />
to the identification,<br />
development and evaluation<br />
of new targeted therapies in<br />
paediatric malignancy.<br />

CANCER GENETICS - CHILDHOOD CANCERS<br />
<strong>The</strong> Programme focuses on<br />
developing agents for poor prognosis<br />
paediatric tumours, including<br />
high-grade glioma (a brain tumour),<br />
rhabdomyosarcoma (a tumour<br />
of muscle), poor prognosis Wilms<br />
tumour (a childhood kidney cancer),<br />
high-risk neuroblastoma (a tumour<br />
of the adrenal glands) and high-risk<br />
leukaemia, as they are the major<br />
causes of death from malignancy<br />
at the present time (see Figure 2).<br />
For example, high-grade astrocytomas,<br />
a type of glioma, in children and<br />
young people are associated with<br />
a very poor prognosis with less<br />
than 10% of children surviving. In<br />
addition, these malignancies are one<br />
of the four major causes of death from<br />
disease in childhood. Furthermore,<br />
high-grade astrocytomas are one of<br />
the very few tumours where there<br />
has been no improvement in survival<br />
with the outcome in <strong>2005</strong> being<br />
identical to that of 1977. Currently,<br />
there is a lack of active compounds<br />
for the therapy of these tumours<br />
with nitrosoureas and temozolomide<br />
being the only established agents.<br />

Unique strengths<br />
Our work is part of the new era of<br />
drug development, which seeks to<br />
exploit the newly acquired knowledge<br />
of the molecular mechanisms that<br />
drive cancer. <strong>The</strong>re are four unique<br />
features of the Paediatric and<br />
Adolescent Oncology Targeted Drug<br />
Development Programme:<br />
1. <strong>The</strong> ability of <strong>The</strong><br />
Institute to design drugs<br />
against targets present<br />
in children’s malignancies<br />
<strong>The</strong> Institute is unique in having the<br />
world’s only fully integrated academic<br />
cancer drug discovery unit and it is<br />
a key objective over the next decade<br />
to develop drugs for children’s cancer<br />
together with the <strong>Royal</strong> <strong>Marsden</strong>.<br />
Identified genes will be evaluated<br />
at the Cancer <strong>Research</strong> UK Centre for<br />
Cancer <strong>The</strong>rapeutics, with the aim<br />
of developing new anticancer agents<br />
for use in children. Genes that have<br />
been identified by teams working<br />
at <strong>The</strong> Institute are related to a range<br />
of conditions, including infant<br />
leukaemia (Professor Mel Greaves,<br />
Section of Haemato-Oncology);<br />
increased susceptibility to Wilms<br />
tumour and neuroblastoma (Professor<br />
Nazneen Rahman, Section of Cancer<br />
Genetics); rhabdomyosarcoma (Dr<br />
Janet Shipley, Section of Molecular<br />
Carcinogenesis and Professor Kathy<br />
Pritchard-Jones, Section of Paediatric<br />
Oncology); high-grade glioma<br />
(Dr Chris Jones, Section of Paediatric<br />
Oncology), and Wilms tumour<br />
(Dr Chris Jones and Professor Kathy<br />
Pritchard-Jones, both Section of<br />
Paediatric Oncology).<br />
As multiple pathways are<br />
involved in cancer<br />
development, the objective<br />
is to identify rationally which<br />
pathways should be targeted<br />
rather than introduce empiric<br />
combination therapy.<br />
For example, Dr Chris Jones (Team<br />
Leader of the Paediatric Molecular<br />
Pathology Team within the Section of<br />
Paediatric Oncology) is engaged in<br />
the identification and validation of<br />
novel molecular targets in Wilms<br />
tumour and high-grade glioma. <strong>The</strong><br />
goal of his work is to identify<br />
genetic alterations in these tumours<br />
which can be exploited in<br />
diagnostic, prognostic/predictive<br />
and therapeutic settings.<br />
By using a technique called<br />
microarray comparative genomic<br />
hybridisation (see Figure 3), the copy<br />
numbers of genes throughout the<br />
human genome are being catalogued<br />
in Wilms tumour and high-grade<br />
glioma. By this means genes which<br />
play a role in childhood cancer can<br />
be identified.<br />
Genes have been identified in Wilms<br />
tumour whose increase appears to<br />
be linked with an increased risk of the<br />
tumour returning after treatment.<br />
22
CANCER GENETICS - CHILDHOOD CANCERS<br />
of chromatin modifying enzymes<br />
(eg, histone deacetylases, histone<br />
methyltransferases and Aurora<br />
kinases) and BRAF inhibitors will<br />
be examined.<br />
Figure 3. Comparative genomic hybridisation onto glass microarray slides has highlighted a<br />
number of novel markers of Wilms tumour relapse<br />
One of these is the receptor tyrosine<br />
kinase IGF1R, whose signalling<br />
pathway is known to be altered<br />
in Wilms tumour and is thought<br />
to play a role in resistance to<br />
chemotherapy in other tumour types.<br />
<strong>The</strong> demonstration that there is an<br />
increase at the DNA, RNA and protein<br />
levels in recurrent Wilms tumour,<br />
highlights the potential for novel<br />
therapeutic strategies aimed at<br />
blocking the receptor in these cells.<br />
if so, these new agents will be<br />
evaluated in childhood cancer.<br />
Novel phosphatidylinositol 3-kinase<br />
(PI3K) inhibitors and HSP90<br />
inhibitors have already been selected<br />
for evaluation in paediatric<br />
malignancy. In the future, inhibitors<br />
3. <strong>The</strong> ability to undertake<br />
studies with biomarkers,<br />
especially those involving<br />
functional imaging<br />
It is essential to know when a new<br />
drug is being evaluated that the<br />
target which the drug has been<br />
designed against has been hit<br />
(modulated). This proof-of-principle<br />
is vital to establish the optimal<br />
drug dose and schedule to maximise<br />
the extent and duration of target<br />
blockade on cancer cell proliferation<br />
and survival. <strong>The</strong> evaluation of<br />
downstream events that occur after<br />
interaction of the drug and target<br />
provides this information. Often,<br />
these biomarkers involve repeated<br />
biopsies of the tumour. This is not<br />
possible in children and therefore<br />
non-invasive methods are needed.<br />
<strong>The</strong> Cancer <strong>Research</strong> UK Clinical<br />
Magnetic Resonance <strong>Research</strong> Group<br />
has a proven international track<br />
record in translational cancer research<br />

causes of death in children's cancer in <strong>2005</strong><br />
2. <strong>The</strong> ability to investigate the<br />
role of drugs developed at the<br />
Cancer <strong>Research</strong> UK Centre for<br />
Cancer <strong>The</strong>rapeutics in children<br />
<strong>The</strong>re is an extensive portfolio of<br />
drug discovery projects at the Cancer<br />
<strong>Research</strong> UK Centre for Cancer<br />
<strong>The</strong>rapeutics. <strong>The</strong>se projects aim to<br />
develop drugs against molecular<br />
targets which are mutated or<br />
inappropriately active in cancer.<br />
<strong>The</strong> first goal is to determine if these<br />
pathways are implicated in cancer<br />
development in glioma,<br />
neuroblastoma (see Figure 4),<br />
leukaemia and rhabdomyosarcoma;<br />

studies will be provided. <strong>The</strong> facility<br />
aims to be a major focus for<br />
early clinical trials in children from<br />
London and the South of England.<br />
Phase I and II clinical trials will be<br />
undertaken with complementary<br />
pharmacology and pharmacodynamic<br />
studies. Functional imaging will<br />
provide important, non-invasive<br />
pharmacodynamic endpoints in<br />
the paediatric population.<br />
Initially, the Unit will have one inpatient<br />
bed and up to two day-care<br />
beds. Clinical care will be provided by<br />
the Oak Foundation Consultant in<br />
Paediatric Drug Development,<br />
Dr Darren Hargrave, the Senior<br />
<strong>Research</strong> Nurse responsible for<br />
Drug Development and the Day<br />
Unit Nurse responsible for Drug<br />
Development, together with existing<br />
consultant, junior medical and<br />
nursing staff of the Children’s Unit<br />
at the <strong>Royal</strong> <strong>Marsden</strong>.<br />
Our aim is to expand to a<br />
four-bed dedicated Oak<br />
Foundation Paediatric and<br />
Adolescent Clinical Drug<br />
Development Unit.<br />
24<br />
and has performed preclinical<br />
magnetic resonance spectroscopy<br />
(MRS) investigations on a range of<br />
molecular targeted therapies which<br />
are now translating through to<br />
clinical trials.<br />
<strong>The</strong> aim is that MRS<br />
measurements may act as<br />
non-invasive biomarkers in<br />
children and that a functional<br />
(molecular) imaging strategy<br />
will be incorporated in Phase<br />
I/II studies of novel agents.<br />
4. <strong>The</strong> ability to efficiently<br />
undertake a large number of<br />
early clinical trials of new drugs<br />
in children and young people<br />
Funding from the Oak Foundation<br />
has made possible the establishment<br />
of the Paediatric and Adolescent<br />
Clinical Drug Development Unit at<br />
the <strong>Royal</strong> <strong>Marsden</strong> in Sutton. When<br />
fully operational, the Unit will be<br />
a specific, comprehensive facility for<br />
the early clinical evaluation of<br />
new anticancer agents in children<br />
and young people with malignancy.<br />
An appropriate clinical research<br />
environment, intensive psychological<br />
support and family accommodation<br />
for children undergoing early clinical<br />
Hot and future topics in<br />
childhood cancer<br />
• <strong>The</strong> long-term goal is that new<br />
anticancer agents, which target<br />
specific molecular pathways, will<br />
be selected rationally for individual<br />
patients. <strong>The</strong>refore, it is important<br />
to know if a child’s tumour<br />
expresses the specific drug target.<br />
This requires increased links with<br />
pathology and the development<br />
of molecular diagnostics.<br />
• Novel phosphatidylinositol 3-kinase<br />
(PI3K) inhibitors developed by the<br />
Cancer <strong>Research</strong> UK Centre for
CANCER GENETICS - CHILDHOOD CANCERS<br />
Cancer <strong>The</strong>rapeutics have been<br />
shown to be active in adult highgrade<br />
glioma cell lines. Initial<br />
evidence suggests that the PTEN/<br />
PI3K pathway could be very<br />
important in high-grade gliomas in<br />
children, a cancer where only 10%<br />
of children survive. Investigations<br />
are ongoing to determine if this<br />
pathway is critical in childhood<br />
gliomas and to determine the<br />
activity of PI3K inhibitors in<br />
childhood high-grade glioma cell<br />
lines. If the pathway is important,<br />
early clinical trials evaluating these<br />
compounds in high-grade gliomas<br />
in children will be carried out;<br />
the studies will incorporate<br />
measurements of biomarkers and<br />
functional imaging.<br />
• With the opening of the Oak<br />
Foundation Paediatric and<br />
Adolescent Clinical Drug<br />
Development Unit and the link<br />
with the Cancer <strong>Research</strong> UK<br />
Centre for Cancer <strong>The</strong>rapeutics,<br />
it is anticipated that there will be a<br />
substantial increase in the number<br />
of new anticancer agents available<br />
for evaluation in children and<br />
young people with cancer and the<br />
number of children entered onto<br />
early clinical trials.<br />
• Another way of predicting if a drug<br />
will work in an individual patient’s<br />
tumour is by measuring the very<br />
early response to the drug using<br />
functional imaging, eg MRS. In this<br />
way, children will only be treated<br />
with a drug if it is known that it will<br />
be effective. By carrying out MRS<br />
studies a few hours after a drug is<br />
given and measuring the effects,<br />
it is hoped to determine if the<br />
compound is going to be active.<br />
This is much faster than the current<br />
methods which require clinical<br />
tumour measurements 6 weeks after<br />
the drug has been given.<br />

individuals to a high risk of breast,<br />
ovarian and other cancers. <strong>The</strong><br />
chance of getting cancer can be so<br />
high, up to an 85% lifetime risk, that<br />
some BRCA mutation carriers elect to<br />
have the at risk organs, breast and<br />
ovary, surgically removed to prevent<br />
these life-threatening diseases from<br />
occurring.<br />
So why does having a defective<br />
version of the BRCA1 or BRCA2 gene<br />
lead to a high risk of developing<br />
cancer Ten years of research from<br />
many labs around the world,<br />
including our own, has generated<br />
a wealth of information providing<br />
insight into this question. Many<br />
believe that normally these genes<br />
are important players in protecting<br />
our genomes from the hostile<br />
environment to which we are all<br />
exposed. Our genetic material,<br />
DNA, is quite a fragile molecule<br />
that is under continual assault from<br />
all sorts of chemical stress,<br />
background radiation, cosmic rays,<br />
sunlight and dietary factors. In<br />
fact, it has been established that<br />
there are 10,000 different bits of<br />
damage to the DNA in every one of<br />
the 100,000,000,000,000 cells<br />
in our bodies every day. Without<br />
elaborate and efficient mechanisms to<br />
fix this damage we would not be<br />
able to survive.<br />
BRCA1 and BRCA2 appear<br />
to be critical for the repair of a<br />
particular type of damage to<br />
DNA which results in the DNA<br />
double helix becoming severed.<br />
When the BRCA1 and BRCA2<br />
genes do not function properly,<br />
which occurs in tumours in<br />
mutation carriers, the ability to<br />
repair these particular DNA<br />
breaks is compromised whereas<br />
other kinds of DNA damage<br />
repair mechanisms are intact. This<br />
dysfunction causes the acquisition<br />
of many other mutations and propels<br />
cancer development.<br />
Treatments to target<br />
BRCA tumours<br />
It is this very property of BRCA<br />
defective cells that we have exploited<br />
in developing new treatment<br />
approaches. We have done this in<br />
two ways. First, we asked which<br />
among the commonly used therapies<br />
for cancer might be best for the<br />
treatment of these particular tumours.<br />
Second, we used our knowledge of<br />
the specific defects caused by BRCA<br />
mutations to develop new and<br />
potentially more effective treatments.<br />
To address the first question, we<br />
performed a series of experiments<br />
comparing the effects of commonly
CANCER BIOLOGY - TARGETED TREATMENTS<br />
used chemotherapies on cells that we<br />
had isolated which contain defective<br />
BRCA1 and BRCA2 genes. We<br />
demonstrated some effect of several<br />
agents but spectacular sensitivity was<br />
seen to the drug carboplatin. Coincidentally<br />
this agent was discovered<br />
at <strong>The</strong> Institute many years ago and is<br />
now one of the most frequently used<br />
cancer drugs in the world. However,<br />
carboplatin is not commonly used for<br />
the treatment of breast cancer.<br />
To test whether carboplatin<br />
might be an effective treatment<br />
for breast cancers arising in<br />
BRCA1 and BRCA2 mutation<br />
carriers, we established the<br />
BRCA Trial 1 clinical study.<br />
<strong>The</strong> trial, supported by Breakthrough<br />
Breast Cancer and Cancer <strong>Research</strong><br />
UK, is the world’s first study to test<br />
a specific treatment for hereditary<br />
breast cancer. During the study,<br />
BRCA1 and BRCA2 mutation carriers<br />
with metastatic breast cancer will<br />
be treated with either carboplatin<br />
or docetaxol, considered the ‘gold<br />
standard’ existing treatment.<br />
Responses to the drugs will be<br />
monitored and compared.<br />
We hope that the trial will resolve<br />
the issue of whether the sensitivity<br />
to carboplatin that we see in the lab<br />
is mimicked in patients in the clinic.<br />
It will be several years before we know<br />
which is the best treatment for this<br />
subtype of breast cancer.<br />
Nevertheless, we have established the<br />
principle that testing whether<br />
genetically different tumours<br />
should receive distinct and specific<br />
treatments can be done in a clinical<br />
trials setting. Furthermore, this trial<br />
will form the framework for testing<br />
new therapeutic approaches in this<br />
subgroup of breast cancers. You can<br />
read more about the BRCA Trial 1 at<br />
www.brcatrial.org.<br />
New therapeutics<br />
<strong>The</strong> BRCA Trial 1 will address the<br />
issue of what is the optimum existing<br />
treatment for cancers arising in<br />
BRCA mutation carriers. But can we<br />
go further and use our knowledge<br />
of the biochemical defects caused by<br />
BRCA mutation to design new<br />
therapeutics Over the last couple of<br />
years, we have made considerable<br />
progress in this area. We envisioned<br />
that a treatment exploiting the<br />
differences between tumour and<br />
normal tissue might not only be<br />

potentially more effective but might<br />
be associated with significantly<br />
reduced toxicity. Our work in this<br />
area has been a close collaboration<br />
with KuDOS Pharmaceuticals, a<br />
biotechnology company based<br />
in Cambridge, UK. Over several years,<br />
KuDOS has been developing<br />
chemicals that block the repair of<br />
certain kinds of DNA damage.<br />
We reasoned that, as BRCA mutant<br />
cells have a specific defect in the<br />
repair of DNA breaks, blocking other<br />
kinds of DNA repair with these<br />
chemicals might have a ‘double<br />
whammy’ effect on the tumour cells<br />
but spare the normal tissues. We<br />
were able to show that chemicals<br />
called PARP inhibitors, which block<br />
the repair of a particular kind of<br />
DNA damage, were spectacularly<br />
effective at killing BRCA1 and<br />
BRCA2 defective cells (see Figures 1<br />
and 2). <strong>The</strong>se cells were around 1000<br />
times more sensitive than cells with<br />
functional BRCA1 and BRCA2. This<br />
enormous difference is hugely<br />
promising for the effectiveness of<br />
these agents and the potential for<br />
minimal side effects.<br />

One reason that made<br />
the discovery that PARP<br />
inhibitors were very<br />
effective in killing BRCA<br />

was the potential for<br />
rapid clinical development.<br />
<strong>The</strong>se drugs are already being<br />
tested in a Phase I clinical trial at<br />
<strong>The</strong> Institute in collaboration with<br />
KuDOS. This type of clinical trial<br />
tests safety and determines the<br />
appropriate dose. We are hoping<br />
that a trial of effectiveness in BRCA<br />
mutation carriers will begin during<br />
2006. Of course the infrastructure<br />
28
CANCER BIOLOGY - TARGETED TREATMENTS<br />
that we have developed for the BRCA<br />
Trial 1 described above will be<br />
very helpful in testing whether PARP<br />
inhibitors are useful drugs for the<br />
treatment of cancers in BRCA carriers.<br />
Future strategies<br />
We are very interested in pursuing<br />
whether similar ‘double whammy’<br />
strategies can be used to treat cancers<br />
arising in individuals who are not<br />
BRCA carriers. <strong>The</strong> issue is: do other<br />
cancers have analogous Achilles’ heels<br />
that we can target We have some<br />
evidence that this is likely to be the<br />
case and that some tumours might<br />
display ‘BRCAness’, that is they seem<br />
to harbour defects in the ability to<br />
repair specific kinds of DNA damage.<br />
<strong>The</strong> challenge we now face is how<br />
to identify these cancers and this is<br />
under vigorous investigation.<br />
If PARP inhibitors prove to<br />
be effective in treating cancer<br />
in BRCA mutation carriers,<br />
it might be possible to roll out<br />
this novel therapeutic<br />
approach into a much larger<br />
group of cancer patients.<br />

Over 40,000 women develop breast<br />
cancer in the UK annually and<br />
the number continues to rise each<br />
year. Encouragingly, however, the<br />
death rate has been falling steadily<br />
over the last ten years. One reason<br />
for this has been the use of medical<br />
treatments immediately after<br />
surgery (so-called adjuvant therapy)<br />
to destroy residual cancer cells.<br />
Recently, the <strong>Royal</strong> <strong>Marsden</strong> Breast<br />
Unit has been at the centre of<br />
exciting new drug developments<br />
in this area. <strong>The</strong> Unit is committed<br />
to working together with <strong>The</strong><br />
Institute’s Academic Department<br />
of Biochemistry and Breakthrough<br />
Toby Robins Breast Cancer <strong>Research</strong><br />
Centre to develop better treatments<br />
for women with breast cancer<br />
through a co-ordinated programme<br />
of laboratory and clinical research.<br />
<strong>The</strong> past year has seen<br />
substantial progress in<br />
our mission with the<br />
announcement of exciting<br />
results from clinical trials<br />
in which the <strong>Royal</strong> <strong>Marsden</strong><br />
has played a major role.<br />
HER2 is a cell surface growth factor<br />
receptor that is over-expressed<br />
in approximately 20% of breast<br />
tumours; these cancers are<br />
characterised by relatively aggressive<br />
disease. Herceptin is a monoclonal<br />
antibody targeted against the HER2<br />
receptor (see Figure 1). Early results<br />
showed that Herceptin can improve<br />
the survival of patients with advanced<br />
HER2-positive breast cancer. During<br />
<strong>2005</strong>, exciting results were reported<br />
from four large trials of adjuvant<br />
Herceptin in early disease. <strong>The</strong> largest<br />
of these (designated HERA) involves<br />
more than 5,000 patients and the<br />
<strong>Royal</strong> <strong>Marsden</strong> has a pivotal role in<br />
this trial including representation on<br />
the Executive Committee (Professors<br />
Mitch Dowsett and Ian Smith).<br />
All four trials showed that Herceptin<br />
reduced the risk of early recurrence<br />
by about 50% and there are already<br />
indications of a marked reduction in<br />
mortality. <strong>The</strong> treatment is very<br />
well tolerated although there can<br />
occasionally be heart complications<br />
in a small proportion of patients<br />
(0.5% in HERA). It is important<br />
that the mechanisms of resistance<br />
to Herceptin are identified so<br />
that further improvements in this<br />
therapeutic approach can be<br />
developed. We are therefore collecting<br />
tumour tissue from around the<br />
world, in a project called TransHERA,<br />

Targeted endocrine therapy<br />
with aromatase inhibitors<br />
<strong>The</strong> aromatase inhibitors are a<br />
new class of endocrine agents which<br />
act by inhibiting the production of<br />
oestrogen in postmenopausal women.<br />
<strong>The</strong> first clinical studies of the most<br />
effective of these, letrozole, were<br />
carried out at the <strong>Royal</strong> <strong>Marsden</strong><br />
more than a decade ago. It was<br />
therefore particularly pleasing for<br />
us when a major new trial (BIG<br />
1-98), which we helped run, recently<br />
reported that letrozole was more<br />
effective than the original gold<br />
standard, tamoxifen, when given<br />
as front-line adjuvant therapy<br />
to patients with early breast cancer.<br />
Another aromatase inhibitor,<br />
anastrozole, has shown similar<br />
superiority to tamoxifen in the ATAC<br />
trial. Again, the <strong>Royal</strong> <strong>Marsden</strong> has<br />
a major role in this trial and during<br />
<strong>2005</strong> we have collected around<br />
1,700 tumour blocks from patients<br />
in the ATAC trial. Our aim is to<br />
understand better the molecular basis<br />
of the advantageous action of<br />
anastrozole and to determine if<br />
there are subgroups of patients that<br />
benefit to different degrees.<br />
Targeted therapies for<br />
BRCA mutations<br />
Professor Alan Ashworth’s<br />
Breakthrough team has been working<br />
for the last ten years on how inherited<br />
defects in the breast cancer genes<br />
BRCA1 and BRCA2 lead to a high risk<br />
of breast cancer in some women<br />
with a very strong family history of<br />
the disease. <strong>The</strong>ir work has also found<br />
a weakness in a specialised form of<br />
DNA repair that may be a potential<br />
‘Achilles’ heel’ of breast cancers that<br />
form in this way (see article by<br />
Professor Alan Ashworth, p.26).<br />
<strong>The</strong> Breast Unit has been<br />
collaborating closely<br />
with Professor Ashworth<br />
and Dr Andy Tutt on<br />
the development of novel<br />
therapeutic strategies to<br />
exploit the specific molecular<br />
defects in women with<br />
BRCA-mutated breast cancer.<br />
Neoadjuvant/preoperative<br />
therapies<br />
For several years, we have been<br />
pioneering an innovative approach in<br />
which breast cancer patients receive<br />
novel chemotherapeutic agents before<br />
rather than after surgery (so-called<br />
neoadjuvant or preoperative therapy).<br />
Collection of serial biopsies of<br />
individual tumours under local<br />
anaesthetic enables us to correlate<br />
early molecular changes with<br />
treatment; this may be predictive<br />
of long-term outcome. Normally,<br />
trials of novel adjuvant therapies after<br />
surgery require many thousands of<br />
patients, many years of follow up and<br />
are extremely expensive to run.<br />
We are hopeful that our approach will<br />
identify effective new drugs much<br />
more quickly. For example, we are<br />
about to start trials with lapatinib,<br />
an oral drug with a broader spectrum<br />
of activity than Herceptin and with<br />
the potential to help a wider range<br />
of patients.<br />
Meanwhile in one of our<br />
previous trials (IMPACT), we found<br />
that endocrine therapy switches<br />
off proliferation to a variable extent<br />
in individual tumours, as measured<br />
by the histochemical marker Ki67.<br />
Long-term results from this trial have<br />
shown that the level of Ki67 two<br />
weeks after starting treatment predicts<br />
for long-term outcome in individual<br />
patients. During 2006, we hope to set<br />
up a large national trial, called<br />
POETIC (Pre-Operative Endocrine<br />
<strong>The</strong>rapy - Individualised Care), to test<br />
this hypothesis further.<br />
If the POETIC trial proves<br />
successful, it would allow<br />
a new and rapid two week<br />
assessment of whether a<br />
particular form of treatment<br />
is going to be effective<br />
in the long-term for<br />
an individual patient.<br />

Diagnosis of cancer<br />
Magnetic resonance (MR) techniques<br />
play a major diagnostic role in cancer,<br />
with significant national resources<br />
directed towards improving their<br />
availability. Rapid technological<br />
advances demand a continuing need<br />
to assess new MR methodologies and<br />
implement them in clinical practice.<br />
With expertise in both<br />
translational research and the<br />
clinical applications of MR, the<br />
Institute / <strong>Marsden</strong> partnership<br />
has a pivotal role in developing<br />
and implementing advances in<br />
MR at a local and national level.<br />
Our primary research focus has<br />
been on refining the role of MR in<br />
cancer diagnosis and staging.<br />
We have also been developing<br />
quantitative methodologies in MR<br />
imaging (MRI) and MR spectroscopy<br />
(MRS). Recently, we have focused<br />
on developing physiological and<br />
metabolic measurement methods to<br />
probe the tumour microenvironment,<br />
validating these against histology<br />
and in clinical trials. Correlation of<br />
MR with genetic data is providing<br />
insights into the function of the<br />
cancer genome. In addition, the use<br />
of functional MR techniques has<br />
allowed us to non-invasively monitor<br />
the effects of new therapies to<br />
identify whether they are behaving<br />
in vivo as they were designed to.<br />
This is vital to the validation of new<br />
therapies in early-stage trials.<br />
Screening women at high<br />
risk of breast cancer<br />
Breast cancer: <strong>The</strong> risk<br />
Some 10% of breast cancer occurs in<br />
women from families with a strong<br />
history of the disease as a result of<br />
inherited genetic alterations. Recently<br />
several genes that are mutated in<br />
familial breast cancer have been<br />
identified (eg, BRCA1 and BRCA2)<br />
and it is now possible to test<br />
individuals for mutations in these<br />
genes (see article by Professor Alan<br />
Ashworth, p.26). While<br />
chemopreventive methods are being<br />
developed, and bilateral prophylactic<br />
mastectomy is an option, regular<br />
surveillance leading to early detection<br />
should minimise the mortality risks<br />
to an individual. <strong>Annual</strong> X-ray<br />
mammography (XRM) is the standard<br />
surveillance offered, but is known to<br />
have limited effectiveness in<br />
premenopausal women as their<br />
breasts are often relatively dense and<br />
thus distinguishing cancer with X-<br />
rays is difficult.<br />
34
IMAGING RESEARCH & CANCER DIAGNOSIS – MAGNETIC RESONANCE<br />
MRI is a sensitive method<br />
of assessing breast cancer in<br />
symptomatic women, and<br />
has been identified as a<br />
potential screening method<br />
for high-risk women, with<br />
its evaluation being an NHS<br />
R&D priority in Cancer.<br />
MARIBS<br />
We established and hosted the<br />
Medical <strong>Research</strong> Council funded<br />
MARIBS study to test whether MRI<br />
screening was better than XRM at<br />
detecting cancer in women at high<br />
risk of breast cancer. We recruited 649<br />
women who received both MRI and<br />
XRM from 22 centres across the<br />
country, offering annual screening for<br />
2-7 years. In women either carrying a<br />
BRCA1 or BRCA2 mutation, or in a<br />
high-risk family with a 50% chance of<br />
being a gene carrier, our results<br />
showed that MRI was almost twice as<br />
sensitive as XRM in detecting cancer.<br />
XRM only detected some 40% of<br />
cancers, whereas MRI detected 77%.<br />
<strong>The</strong> combination of MRI and XRM<br />
detected 94% of cancers, which is a<br />
good performance for a screening<br />
test. We were also able to look at<br />
effectiveness in women with a specific<br />
gene mutation. In BRCA1 carriers,<br />
MRI was four times better than XRM<br />
and XRM did not detect any cancers<br />
missed by MRI. While the cancers due<br />
to BRCA1 and BRCA2 mutations differ<br />
biologically from the normal<br />
population, we detected a similar<br />
proportion of small cancers to the<br />
NHS Breast Screening Programme<br />
(NHSBSP), and our recall and benign<br />
surgical biopsy rate per cancer<br />
detected were similar to the NHSBSP<br />
(see Figure 1). Cancer <strong>Research</strong> UK<br />
has funded a follow on study, to be<br />
led by Dr Ros Eeles (Section of Cancer<br />
Genetics), to investigate the<br />
interaction of MRI appearance and<br />
genetic status.<br />
Based on results from MARIBS<br />
and other recent trials, bodies<br />
such as the National Institute<br />
for Clinical Excellence and the<br />
American Cancer Society<br />
are considering revising their<br />
guidelines for surveillance<br />
of women at high risk of<br />
breast cancer.<br />

Diffusion-weighted MRI<br />
Diffusion-weighted magnetic<br />
resonance imaging (DW-MRI)<br />
provides image contrast through<br />
measurement of the properties<br />
of water within tissues. In a highly<br />
cellular tissue, water cannot diffuse<br />
far during the MR observation<br />
period without being blocked by<br />
cell membranes (see Figure 2).<br />
Conversely, in cystic or necrotic<br />
tissues with fewer structural barriers,<br />
the diffusional path-length of<br />
extracellular water is longer. Apparent<br />
diffusion coefficient (ADC) maps,<br />
derived from DW-MRI, therefore<br />
provide a non-invasive measure of<br />
cellularity. In cancer imaging this<br />
has potential for diagnosis, treatment<br />
planning and monitoring response.<br />
This approach is proving valuable,<br />
as changes in ADC values are<br />
measurable earlier than conventional<br />
imaging response indicators.<br />
DW-MRI can be exploited to<br />
improve tumour detection<br />
and differentiate benign from<br />
malignant lesions.<br />
DW-MRI and tumour<br />
detection<br />
In prostate cancer, we have shown<br />
that the addition of DW-MRI<br />
identifies tumour lesions with greater<br />
A<br />
certainty than using conventional<br />
imaging alone (see Figure 3).<br />
Additionally, the ADC values of<br />
malignant prostate nodules appear<br />
to be lower than those of nonmalignant<br />
prostate nodules; we are<br />
validating our results with<br />
prostatectomy (this work is funded<br />
by the <strong>Royal</strong> <strong>Marsden</strong> Hospital<br />
Charity). We are also exploring ADC<br />
as a measure of tumour aggressiveness<br />
in patients opting to have their<br />

Dr Parker, p.51). In contrast, liver<br />
metastases show greater diffusivity<br />
(higher ADC) than normal liver<br />
tissue. We have shown that<br />
DW-MRI adds confidence to the<br />
detection of liver metastases when<br />
used in conjunction with contrastenhanced<br />
imaging.<br />
Predicting tumour response<br />
to treatment<br />
Quantitative DW-MRI has the<br />
potential to predict tumour response<br />
to treatment. In patients with locally<br />
advanced rectal cancer, low pretreatment<br />
tumour ADC (indicative of<br />
highly cellular lesions) predicted a<br />
greater reduction in tumour size after<br />
chemotherapy. Similarly in liver<br />
deposits, we have observed that a<br />
high pre-treatment ADC (greater<br />
diffusivity and more necrosis likely)<br />
predicted for a poor<br />
chemotherapeutic response.<br />
Monitoring response to<br />
treatment<br />
Experimental studies report that<br />
an increase in ADC values early<br />
after treatment initiation is associated<br />
with cell death and a subsequent<br />
reduction in tumour volume. In<br />
clinical studies of breast and liver<br />
tumours, ADC values also increase<br />
early in good responders and are<br />
potentially of value in identifying<br />
response within a much shorter<br />
time scale than changes in tumour<br />
volume. In collaboration with<br />
the Department of Medicine Drug<br />
Development Unit, we are<br />
incorporating DW-MRI into our<br />
evaluation of the therapeutic<br />
effects of new drugs.<br />
<strong>The</strong> clinical utility of DW-<br />
MRI will be expanded to<br />
complement conventional<br />
functional MR and CT<br />
measures of response as well<br />
as modalities such as PET.<br />
Interrogating tissue<br />

What is MRS<br />
Magnetic resonance spectroscopy<br />
(MRS) measures signals from MRvisible<br />
elements (eg, 1-Hydrogen,<br />
19-Fluorine, 31-Phosphorus), and<br />
allows different molecules to<br />
be identified due to characteristic<br />
changes in resonant frequency<br />
that relate to the specific chemical<br />
structure of the molecule. MRS<br />
provides a non-invasive window<br />
on metabolism in vivo as several<br />
metabolites may be detected in one<br />
measurement. Our research is focused<br />
on using MRS to detect metabolic<br />
alterations associated with inhibition,<br />
by novel therapeutics, of specific<br />
pathways that are activated in cancer.<br />
<strong>The</strong>se MRS changes are being<br />
evaluated in well-controlled cell<br />
systems with a view to utilising them<br />
in forthcoming clinical trials of these<br />
new agents.<br />
In collaboration with the Cancer<br />
<strong>Research</strong> UK Centre for Cancer<br />
<strong>The</strong>rapeutics based at <strong>The</strong> Institute,<br />
we have used MRS to assess whether<br />

chaperone) or enzymes (eg, choline<br />

alterations that may be used as<br />
biomarkers of inhibition of those<br />
pathways in vivo.<br />
Many signalling pathways<br />
that promote cell growth and<br />
survival are deregulated in<br />
human cancer. Inhibition of<br />
these pathways forms the basis<br />
of development of many new,<br />
targeted anticancer drugs.<br />
Monitoring pathways involved<br />
in cell growth<br />
In several human cancer cell lines, we<br />
have shown that specific cell growth<br />
pathway blockade (eg, with the MEK<br />
inhibitor U0126) was associated with<br />
a decrease in the membrane precursor<br />
phosphocholine (PC), which is<br />
normally elevated in cancer (see<br />
Figure 4). This decrease was associated<br />
with inhibition of proteins that are<br />
normally activated by these pathways<br />
(eg, phosphorylated ERK1/2 and Akt),<br />
and preceded the downstream cellular<br />
consequences of pathway inhibition<br />
such as cell cycle arrest or growth<br />
inhibition.<br />
Monitoring protein inhibition<br />
PC can be measured in vivo in<br />
patients, and therefore may be used<br />
as a non-invasive biomarker to<br />
monitor the therapeutic action of<br />
targeted drugs in clinical trials. An<br />
example of such an approach is in the<br />
inhibition of HSP90, a molecular<br />
chaperone important in assembling<br />
intermediaries in a number of key<br />
pathways upregulated in cancer.<br />
Using MRS measurements we have<br />
shown that inhibitors of HSP90 such<br />
as 17-AAG cause characteristic<br />
changes in the phosphorus spectrum<br />
in cells and in vivo.<br />
Based on our research,<br />
clinical MRS has been<br />
incorporated into two<br />

UK Biomedical MR Group (St George’s,<br />
University of London), we are also<br />
investigating whether MRS provides<br />
non-invasive biomarkers that indicate<br />
inhibition of the enzyme choline<br />
kinase (ChoK). This enzyme catalyses<br />
the formation of membrane precursor<br />
PC from its precursor choline. Due<br />
to the elevated levels of PC in cancer<br />
cells, inhibition of ChoK leads to<br />
cell death in these cells and thus<br />
provides a target for anticancer drug<br />
development. Treatment with a<br />
specific ChoK inhibitor resulted in<br />
a decrease in choline-containing<br />
metabolites that correlated well with<br />
the decrease in ChoK.<br />
<strong>The</strong> future of MR<br />
Our imaging programme focuses on<br />
understanding the processes of<br />
tumour evolution and response to<br />
treatment by studying cell systems,<br />
whole tissues, and xenografts, and<br />
integrating this with our clinical<br />
studies. We aim to identify the<br />
molecular signatures of tumours and<br />
their functional characteristics in<br />
order to map morphological and<br />
functional tumour heterogeneity.<br />
This will allow us to better<br />
characterise disease, more accurately<br />
assess response, and will aid<br />
stratification of patients for targeted<br />
therapies, leading to a more tailored<br />
approach to managing individual<br />
tumours in order to maximise<br />
treatment safety and efficacy. By<br />
evaluating whether new treatments<br />
are acting as intended, these<br />
techniques will help speed up drug<br />
development and progress new<br />
agents into the clinic. <strong>The</strong> use of<br />
functional imaging methods will<br />
then help identify at an early stage<br />
in treatment whether these new<br />
therapies are working in individual<br />
patients. We aim to improve the<br />
sensitivity and accuracy of our<br />
techniques by transferring them to<br />
a new state-of-the-art 3T clinical<br />
magnetic resonance system.<br />

Structural biology is an advancing discipline that has major<br />
implications for the streamlined development of novel therapeutics<br />
for the targeted treatment of cancer.<br />

Genetic and biological<br />
insights into cancer<br />
New genetic insights into the biology<br />
of tumours increasingly allow us to<br />
pinpoint precisely the genes whose<br />
mutation or disregulation underlie<br />
the disorganised and unregulated<br />
cellular behaviour we recognise as<br />
cancer. However, knowledge<br />
of the gene is not enough, and if<br />
we are going to understand<br />
how these genetic changes exert their<br />
effect, and be able to counteract<br />
them, we have to look at the proteins<br />
encoded by the affected genes.<br />
Structural biology and drug<br />
development<br />
<strong>The</strong> techniques of structural biology<br />
(X-ray crystallography, single-particle<br />
electron microscopy) can provide<br />
an unparalleled level of detailed<br />
information on the structure of<br />
proteins involved in the aetiology<br />

and treatment of cancer. Knowledge<br />
of the three-dimensional structure<br />
of a protein provides enormous basic<br />
scientific insights into the function<br />
of that protein. It allows us to define<br />
its biochemical mechanism,<br />
understand how it interacts with<br />
other proteins, RNA, DNA or<br />
membranes in the cell, and how<br />
cancer-linked mutations in its<br />
structure alter its normal function.<br />
Most importantly for improving<br />
patient care, knowing the threedimensional<br />
structure of a protein<br />
tells us directly how novel drugs<br />
can inhibit its excessive/<br />
unregulated activity.<br />
Structural biology sits at a key<br />
interface between basic and<br />
translational research, and this<br />
importance is reflected in the<br />
considerable investment <strong>The</strong><br />
Institute has made in this field<br />
in the last few years.<br />
Traditional drug<br />
development<br />
Traditional chemotherapeutic agents<br />
have a broad range of activities in<br />
the cell, many of which contribute<br />
to their general cytotoxicity, and<br />
unpleasant and dangerous side-effects.<br />
In principle, novel drugs targeted<br />
at a single protein in the cell should<br />
only disrupt the pathways involving<br />
that protein and as such have far<br />
fewer side-effects. However, developing<br />
drug molecules with that level of<br />
specificity and selectivity is far from<br />
straightforward, as common<br />
and important targets such as<br />
protein kinases share many<br />
biochemical features.<br />
Conventional approaches to<br />
achieving selectivity rely on<br />
medicinal chemists generating a wide<br />
range of variants around the basic<br />
Figure 2. Crystal structure of the kinase domain from an oncogenic form of BRAF protein<br />
(cartoon), bound to the inhibitor Bayer 439006 (stick model). New compounds based on this<br />
and other inhibitor classes are in development at <strong>The</strong> Institute.<br />
chemical composition of a ‘hit’ drug,<br />
and testing these for their ability<br />
to inhibit the target protein as well<br />
as a range of related proteins. By<br />
retaining those modifications that<br />
improve efficacy against the target,<br />
and avoiding those that inhibit<br />
related off-target proteins,<br />
the medicinal chemists are able to<br />
feel their way through a complex<br />
chemical landscape with the starting<br />
drug eventually being ‘evolved’<br />
to a sufficient degree of efficacy<br />
and specificity.<br />
Drug development using<br />
traditional medicinal<br />
chemistry can take a long time<br />
even when there are clear<br />
structure-activity relationships.<br />
Advances made by the<br />
Section of Structural Biology<br />
at <strong>The</strong> Institute aim to<br />
streamline this process.<br />

Advances in drug<br />
development<br />
With our expertise in structural<br />
biology, Institute scientists are able to<br />
short-circuit the traditional laborious<br />
drug development approach, cutting<br />
years off the process. Once a starting<br />
‘hit’ drug molecule for a particular<br />
target has been identified, we cocrystallise<br />
it with the target protein<br />
and determine the structure of the<br />
complex. At a simple level, this helps<br />
validate the original identification<br />
of the ‘hit’ molecule and confirm its<br />
identification as an inhibitor. Most<br />
importantly, it shows us in precise<br />
atomic detail, which parts of the ‘hit’<br />
drug molecule are actually making<br />
contacts with the target protein, and<br />
therefore cannot be modified without<br />
losing efficacy, and which parts of<br />
the ‘hit’ drug molecule can be<br />
changed to enhance pharmacological<br />
properties such as oral availability<br />
and persistence in tissues. By<br />
comparing the crystal structures of<br />
the same ‘hit’ drug molecule bound<br />
to target and off-target proteins, we<br />
can also greatly improve specificity,<br />
by identifying modifications that will<br />
allow it to bind to the target protein,<br />
but make it incompatible with the<br />
off-target proteins.<br />
Structure-based programmes<br />
within the Section of Structural<br />
Biology have already made<br />
very important contributions<br />
to the development of novel<br />
drugs, and have been<br />
instrumental in moving these<br />
projects into collaborations<br />
with the Biotech and<br />

PKB protein kinase inhibitors<br />
<strong>The</strong> serine/threonine protein kinase<br />

important role in the generation<br />

Professor David Barford’s group<br />
in the Section of Structural Biology<br />
devised methods to obtain active<br />

virtual screening, high-throughput<br />

led to the development of four<br />
distinct chemical series of highly<br />

BRAF protein kinase inhibitors<br />
Collaborative work between the<br />

Project directed by Professor Mike<br />
Stratton (Section of Cancer Genetics),<br />
and Professor Chris Marshall and<br />
Dr Richard Marais (Cancer <strong>Research</strong><br />
UK Centre for Cell and Molecular<br />
Biology) showed that the protein<br />
kinase BRAF is mutated in<br />
approximately 70% of malignant<br />
melanomas and a significant number<br />
of colorectal, ovarian and papillary<br />
thyroid cancers, implicating mutated<br />
BRAF as a critical promoter<br />
of malignancy.<br />
In collaboration with Dr Richard<br />
Marais and Professor Caroline<br />
Springer (Cancer <strong>Research</strong> UK Centre<br />
for Cancer <strong>The</strong>rapeutics), Professor<br />
Barford’s group determined the<br />
structure of the BRAF catalytic<br />
domain and identified a class of BRAF<br />
inhibitors that bind to the active<br />
conformation of the protein (see<br />
Figure 2). Further lead series were<br />
developed and crystal structures of<br />
complexes combined with molecular<br />
modelling studies have resulted in<br />
potent inhibitors.<br />
HSP90 molecular<br />
chaperone inhibitors<br />
HSP90 is a ‘molecular chaperone’,<br />
required for the stable folding<br />
and activation of a plethora of cell<br />
regulatory proteins, many of which<br />
are disregulated and/or mutated in<br />
cancer. Mutated protein kinases such<br />
as BRAF and BCR-ABL, which drive<br />
many types of cancer, are particularly<br />
dependent on HSP90, so that<br />
inhibition of HSP90 offers an<br />
exciting therapeutic approach with<br />
the possibility of application to<br />
a broad spectrum of tumour types.<br />
We determined the crystal structure<br />
of key parts of the HSP90 protein<br />
and showed how several natural<br />
product small molecules could<br />
act as specific inhibitors of the<br />
chaperone’s essential ATPase activity<br />
(see Figure 3). In collaboration with<br />
Professor Paul Workman and Drs<br />
Wynne Aherne and Ted McDonald<br />
(Cancer <strong>Research</strong> UK Centre for<br />
Cancer <strong>The</strong>rapeutics) we developed<br />
a high-throughput screen for HSP90<br />
ATPase inhibitors, and identified and<br />
characterised CCT018159 – the first<br />
in a novel class of synthetic HSP90<br />
inhibitors. <strong>The</strong>se new compounds<br />
were further developed in<br />
collaboration with Cancer <strong>Research</strong><br />
Technology Ltd and Vernalis, and<br />
Professor David Barford and crystallography equipment<br />
have now been licensed to Novartis<br />
with the prospect of clinical trials<br />
commencing this year.<br />
<strong>The</strong> future of<br />
structural biology<br />
<strong>The</strong> Section of Structural Biology<br />
at <strong>The</strong> Institute has undergone<br />
substantial expansion in the last year,<br />
with the recruitment of X-ray<br />
crystallography teams working on<br />
the structural biology of mitotic<br />
regulation (Dr Richard Bayliss) and<br />
chromatin regulation (Dr Jon<br />
Wilson), and the inauguration of<br />
the structural electron microscopy<br />
team led by Dr Ed Morris. <strong>The</strong><br />
facilities, resources and expertise<br />
we have been able to assemble will<br />
keep structural biology at <strong>The</strong><br />
Institute at the international forefront<br />
in both basic research and in its<br />
translation to patient benefit.<br />

SLEUTHING THE CAUSES OF<br />
CHILDHOOD LEUKAEMIA<br />
Whilst more biologically directed and less toxic therapy<br />
is a realistic goal, finding out what causes leukaemia and whether<br />
it is potentially preventable are critically important issues.<br />
<strong>The</strong> challenge<br />

Institute of Cancer <strong>Research</strong><br />
Acute leukaemia is the major subtype<br />
of paediatric cancer in developed<br />
societies. Each year in the UK, there<br />
are some 500 diagnoses of this disease<br />
which translates to an accumulative<br />
risk of around 1 in 2000 (between<br />
the ages of 0 and 15 years).<br />
Treatment of leukaemia in children,<br />
with combination chemotherapy in<br />
the context of controlled clinical<br />
trials, has been an extraordinary<br />
success story. Overall, cure rates are<br />
now around 80% but with variation<br />
between different cellular and<br />
molecular subtypes of the disease.<br />
Despite this progress, much remains<br />
to be achieved.<br />
Some subtypes of leukaemia<br />
remain refractory to effective<br />
eradication and high-dose<br />
chemotherapy is toxic,<br />
particularly to developing<br />
infants and toddlers with<br />
consequent long-term<br />
collateral damage.<br />
Decades of speculation on causation<br />
have spawned a plethora of candidate<br />
exposures that might be relevant<br />
(see Table 1). For most of these<br />
factors, the evidence is at best fragile<br />
and inconsistent. Given the biological<br />

diversity of the disease, it is highly<br />
unlikely that a single cause exists.<br />
We know that a small fraction (2-5%)<br />
of cases involve strong inherited<br />
predisposition and, from previous<br />
genetic epidemiological research in<br />
our Section, that infant leukaemias<br />
with MLL gene fusions almost<br />
certainly have a unique aetiology<br />
involving transplacental chemical<br />
mutagenesis in utero.<br />
<strong>The</strong> key question however is<br />
whether there is a major mechanism<br />
accounting for the common variety<br />
of leukaemia, B cell precursor<br />
acute lymphoblastic leukaemia (ALL),<br />
that accounts for the marked peak<br />
incidence of the disease between<br />
2 and 5 years of age (see Figure 1).<br />
<strong>Research</strong> in the Section of<br />
Haemato-Oncology has taken<br />
us close to an answer.<br />
Infection as a trigger<br />
Speculation that childhood<br />
leukaemia might have an infectious<br />
causation is more than 70 years old<br />
and has been encouraged by parallels<br />
with virus-associated leukaemias<br />
in domesticated cats, cattle and<br />
chickens. Several other human blood<br />
cell cancers are known to be linked<br />
to specific viral or bacterial infections.<br />
To date, however, all attempts by<br />
us and other scientists to identify<br />
footprints of transforming viruses<br />
in childhood ALL, via sensitive<br />
molecular screening, have been<br />
uniformly negative. Whilst this could<br />
be a misleading result, it nevertheless<br />
encourages an alternative view that<br />

we first proposed back in 1988,<br />
namely that the causal mechanism<br />
is an abnormal immune response to<br />
one or more viral or bacterial species<br />
(ie, an indirect effect of infection).<br />
In developing this model,<br />
we have placed considerable<br />
emphasis on our laboratorybased<br />
insights into the<br />
molecular pathogenesis<br />
and natural history of<br />
childhood ALL.<br />
Our working ‘2 hit’ model, now<br />
proven by extensive data sets,<br />
has three critical features (see Figure<br />
2). Firstly, a bottleneck in the<br />
development of leukaemia is the<br />
transition between covert preleukaemia<br />
and overt malignant<br />
disease. We know that this occurs in<br />
only ~1% of cases with pre-leukaemic<br />
clones. Secondly, an abnormal<br />
immune response triggers the<br />
essential second hit. And thirdly,<br />
an abnormal immune response<br />
can arise as a consequence of delayed<br />
exposure to infection in infancy<br />
plus a skew in response that is<br />
genetically inherited. This hypothesis<br />
led to two testable predictions:<br />
1. that a deficiency of infectious<br />
exposures in the first year of life<br />
should increase subsequent risk<br />
of ALL<br />
2. that risk should be associated<br />
with inherited genetic variation<br />
in immune response genes.<br />
<strong>The</strong> key data<br />
<strong>The</strong> UK Children’s Cancer Study<br />
(UKCCS) was a major nationwide<br />
case/control epidemiological study<br />
of the possible causes of childhood<br />
cancer. Our laboratory provided<br />
the central resource for molecular<br />
sub-classification of cases (and<br />
storage of diagnostic DNA). Professor<br />
Julian Peto and colleagues in the<br />
Section of Epidemiology were one<br />
of the nine regional centres for<br />
administering the very detailed<br />
questionnaire and for some of the<br />
important data analysis.<br />
<strong>The</strong> UKCCS, the largest<br />
study of its kind worldwide to<br />
date, found no evidence to<br />
implicate ionising radiation,<br />
non-ionising electric fields<br />
or electro-magnetic fields in<br />
the causation of leukaemia.<br />
We sought two lines of evidence<br />
that, if positive, would endorse<br />
an abnormal response to infection as<br />
a credible explanation. In the first,<br />
we analysed the association between<br />
exposure to other children outside<br />
the home (in playgroups and as<br />
a surrogate for infectious exposure)<br />
and risk of ALL. As predicted by our<br />
‘delayed infection’ idea, we found<br />
that infants with more social contacts<br />
(and presumed infections) had<br />
a reduced risk of ALL (see Figure 3).<br />
This result has been replicated<br />
by a California-based case/<br />
control study that adapted the<br />
UKCCS questionnaire.<br />
Our second testable prediction<br />
was that susceptibility to ALL should<br />

particular normal variants (ie, not<br />
mutations) of critical genes that<br />
regulate the immune system.<br />
<strong>The</strong> starting point for this was to<br />
interrogate the HLA gene system<br />
since this is a well-established<br />
genetically variable locus critical to<br />
immune response to infection.<br />
A significant positive association<br />
with risk of ALL was found with<br />
a gene variant called HLA.DPB1 0201*<br />
(see Figure 3).<br />
<strong>The</strong>se data do not prove our case<br />
but they greatly endorse its credibility.<br />
Independent epidemiological data<br />
collated by Professor Leo Kinlen<br />
(Oxford University) have similarly<br />
linked risk of childhood leukaemia<br />
with social opportunities for<br />
infection; in his case in the context<br />
of transient ‘clusters’ of leukaemia<br />
and population mobility/mixing.<br />
So what next<br />
Now that the hypothesis and model<br />
have accepted credence, the next<br />
urgent step is to put some flesh on<br />
the bones. To achieve this, two things<br />
are essential. Firstly, a more extensive<br />
genetic analysis of immune response<br />
genes and risk is needed. A study<br />
using human genome-based SNP<br />
sequences for ‘candidate’ genes that<br />
regulate the establishment of the<br />
immune response cellular network<br />
in infancy has been initiated in the<br />
Section of Haemato-Oncology with<br />
Professor Gareth Morgan and Dr Zara<br />
Josephs. <strong>The</strong> SNP sequences include<br />
genes for cytokines such as IL-10,<br />
IL-12 and TGF‚.<br />
<strong>The</strong> size of the UKCCS sample<br />
set provides us with a unique<br />
opportunity to pin down<br />
genetic associations of ALL<br />
with the immune system.<br />
Secondly, we need to provide a<br />
mechanistic explanation for how<br />
an aberrant or dysregulated immune<br />
response to infection can ‘select’<br />
pre-leukaemic cells such that they<br />
are at high risk of the disease<br />
precipitating secondary mutations<br />
(see Figure 2). To this end, Dr Tony<br />
Ford in our laboratory has developed<br />
a tissue culture model system<br />
in which the predominant ALL<br />
initiating gene (TEL-AML1 fusion<br />
gene) can be switched on and<br />
off at will. Using this model,<br />
a PhD student, Miss Chiara Palmi,<br />
has already discovered that cells<br />
expressing this ‘1st hit’ leukaemic<br />
gene are selectively resistant to a<br />
growth-inhibiting immune response<br />
cytokine (TGF‚).<br />
Other groups in the UK and<br />
internationally will certainly be<br />
looking at genetic variation in<br />
immune response genes (and other<br />
genes), and consistent associations<br />
with childhood ALL in large studies<br />
will be essential. Our team has been<br />
the only group worldwide exploring<br />
the molecular pathogenesis of<br />
childhood ALL from the perspective<br />
of natural history and aetiology.<br />
Whilst we will seek to maintain<br />
our pole position, it is to be<br />
anticipated and welcomed that<br />
others will now seek to explore<br />
this important issue. <strong>The</strong> potential<br />
rewards are considerable; the<br />
identification of the major causal<br />
mechanism of childhood leukaemia<br />
and its possible future prevention.<br />

<strong>The</strong> BRAF protein is a key part of a molecular signalling pathway that enables cells to<br />

as such, the protein represents a specific potential drug target.<br />

Melanoma: <strong>The</strong> problem<br />
Malignant melanoma is a serious<br />
public health problem in that its<br />
incidence is increasing every decade<br />
(see Figure 1). Each year, more than<br />
7,000 patients develop melanoma<br />
in the UK and there are over 1,500<br />
deaths. A number of genetic factors<br />
predispose people to melanoma but<br />
those with fair hair and skin, multiple<br />
moles and episodes of severe burning<br />
in childhood are at most risk. <strong>The</strong>re is<br />

evidence from Australia that sun<br />
avoidance campaigns and systems<br />
that allow for the early removal of<br />
suspicious moles can all help reduce<br />
the death rate from melanoma. Early<br />
diagnosis of melanoma is important<br />
because it reduces the chances of the<br />
disease progressing to the metastatic<br />
stage, when it attains the ability to<br />
disseminate to other sites including<br />
the vital organs. Metastatic disease<br />
is particularly difficult to treat<br />
and has a very poor prognosis, with<br />

a 5-year survival rate of less than 5%.<br />
Patients are at risk of disease<br />
dissemination if they have a thick<br />
primary lesion or the disease has<br />
spread to local lymph nodes.<br />
<strong>The</strong> Melanoma Unit has<br />
played a major role in many<br />
trials of adjuvant therapy<br />
in high-risk melanoma<br />
populations using a number<br />
of therapeutic strategies<br />
including vaccination and<br />
interferon therapy.<br />
Despite our efforts, there is<br />
still no effective treatment for<br />
malignant melanoma. <strong>The</strong><br />
results of chemotherapy have been<br />
disappointing and immunotherapies<br />
have similarly not shown a survival<br />
benefit for these patients. For patients<br />
with the disseminated disease,<br />
the prognosis remains very poor with<br />
a median survival of 6 months.<br />
Treatment of patients once their<br />
disease has disseminated is palliative,<br />
and the main focus of the Unit’s<br />
activity over the last 15 years has<br />
been to try and develop therapies that<br />
can impact the metastatic disease.<br />
Vaccination for melanoma<br />
Clinicians within the <strong>Royal</strong><br />
<strong>Marsden</strong> together with scientists at<br />
<strong>The</strong> Institute developed the first<br />
genetically modified vaccine against<br />
cancer in the UK. This vaccine<br />
utilised the patient’s own tumour<br />
cells, and the gene encoding a<br />
biological factor called interleukin 2<br />
was inserted into the cells prior to<br />
vaccination. <strong>The</strong> study showed that<br />
patients who developed an immune<br />
response to the vaccine lived longer<br />
than those who did not. <strong>The</strong>re were<br />
two long-term survivors from this<br />
trial, one of whom has remained<br />
disease free for nearly ten years.<br />
Parallel to this trial, the Unit<br />
worked with colleagues in the<br />
European Organisation for <strong>Research</strong><br />
and Treatment of Cancer (EORTC)<br />
Melanoma Group to develop<br />
new chemotherapy strategies<br />
that combined conventional<br />
chemotherapy, interleukin 2 and<br />
another biological agent, interferon.<br />
Large randomised trials failed<br />
to show a benefit for this approach<br />
and so the Unit together with<br />
<strong>The</strong> Institute altered its research<br />
strategy, with the Unit becoming<br />
a major contributor to one of<br />
the largest randomised trials ever<br />
performed in melanoma. In this<br />
trial, a new type of drug, called<br />
an anti-sense molecule, which targets<br />
a protein called BCL2 (believed<br />
to be involved in melanoma tumour<br />
cell survival), was combined<br />
with conventional chemotherapy.<br />
This novel approach had some<br />
minor success in that it extended<br />
the progression-free survival of<br />
the patients, but unfortunately, it did<br />
not impact on overall survival.<br />
In 2002, our work at <strong>The</strong><br />
Institute, in collaboration with<br />
colleagues from the Wellcome<br />
Trust Sanger Institute, led to<br />
an exciting and unexpected<br />
discovery that a protein called<br />
BRAF is mutated in around<br />
70% of malignant melanomas.<br />
BRAF and melanoma<br />
BRAF, a member of a protein family<br />
called the protein kinases, regulates<br />
the growth of cells during normal<br />
functions such as cell development<br />
and wound healing. Our ongoing<br />
work at <strong>The</strong> Institute demonstrated<br />
that mutated BRAF is locked in the<br />
active state and therefore it sends a<br />
continual growth signal to cancer<br />
cells. This causes the cells to grow in<br />
an uncontrolled manner and also<br />
makes them very resistant to death.<br />
We also demonstrated that the<br />
activity of mutant BRAF could be<br />
blocked by sorafenib, a drug that was<br />
undergoing clinical trials for other<br />
types of cancer. Sorafenib had been<br />
developed to inhibit the activity of<br />
a closely related protein called CRAF,<br />
and these proteins are sufficiently<br />
similar that sorafenib also had some<br />
activity against BRAF.<br />
Targeting BRAF for<br />
melanoma treatment<br />
<strong>The</strong> Melanoma Unit, in collaboration<br />
with two other institutions in the<br />
USA, initiated a number of clinical<br />
trials to determine if sorafenib<br />
had activity against mutant BRAF in<br />
melanoma patients. However, it<br />
quickly became apparent from work<br />
conducted with other clinical and<br />
scientific colleagues at <strong>The</strong> Institute<br />
and <strong>Royal</strong> <strong>Marsden</strong> that the major<br />
clinical effect of sorafenib was in<br />
renal cell carcinoma, a disease that is<br />
not associated with mutant BRAF.<br />
This may be because sorafenib is not<br />
sufficiently potent to directly target<br />
BRAF in melanoma. Nevertheless,<br />
there is evidence that sorafenib can<br />
be combined with other forms<br />
of chemotherapy to produce some<br />
responses in melanoma.<br />
<strong>The</strong> <strong>Royal</strong> <strong>Marsden</strong><br />
and <strong>The</strong> Institute have taken<br />
the international lead in<br />
developing a combination of<br />
sorafenib and darcarbazine for<br />
the treatment of melanoma;<br />
the potential of this combined<br />
chemotherapy is currently<br />
being tested.<br />

scientific findings to the clinic with<br />
exceptional speed. Furthermore,<br />
the feedback from the clinician allows<br />
the scientist to address clinically<br />
relevant questions and then adjust<br />
and test their hypotheses in a<br />
clinically relevant situation. <strong>The</strong><br />
ability to conduct fundamental<br />
research-based clinical studies puts us<br />
in an excellent position to develop<br />
new therapies for the treatment of<br />
melanoma and other cancers.<br />
HSP90 and BRAF<br />
As part of our ongoing efforts<br />
in the basic research area, we have<br />
examined other approaches to<br />
target BRAF in melanoma and have<br />
discovered an exciting alternative<br />
approach. Another protein called<br />
HSP90 is responsible for the correct<br />
function of BRAF. When HSP90<br />
activity is blocked, BRAF cannot<br />
function and becomes destroyed by<br />
specialist machinery in the cell.<br />
We have shown that a drug called<br />
17-AAG, which blocks the function<br />
of HSP90, causes destruction of<br />
mutant BRAF. Importantly, we have<br />
shown that mutant BRAF is more<br />
sensitive to 17-AAG than normal<br />
BRAF, providing a therapeutic<br />
selectivity against the function<br />
of the mutant protein.<br />
17-AAG is currently being<br />
tested at the <strong>Royal</strong> <strong>Marsden</strong><br />
and <strong>The</strong> Institute against<br />
melanoma and a range of<br />
other cancers.<br />
We are also combining our laboratory<br />
and clinical studies to test other<br />
compounds that may target BRAF<br />
in cancer. For example, the<br />
downstream target of BRAF in cells is<br />
a protein kinase called MEK (see<br />
article by Professor Martin Leach and<br />
Dr Nandita deSouza, p.34). We are<br />
currently exploring the potential of<br />
using compounds that target this<br />
kinase in the laboratory and the<br />
clinic. Finally, we are conducting a<br />
major programme to develop new<br />
agents that directly target BRAF. <strong>The</strong><br />
specific aim is to develop drugs<br />
that will enable us to treat melanoma<br />
patients by directly targeting mutant<br />
BRAF. <strong>The</strong>se drugs may also prove<br />
useful for other cancers that rely on<br />
mutant BRAF, such as colorectal<br />
and thyroid cancer. This work, being<br />
conducted at <strong>The</strong> Institute of Cancer<br />
<strong>Research</strong>, is a collaboration between<br />
<strong>The</strong> Institute, the Wellcome Trust<br />
and Cancer <strong>Research</strong> UK.<br />
Laboratory and clinical<br />
collaboration: <strong>The</strong> future<br />

settings allows us to translate our<br />

Prostate cancer:<br />
Occurrence and risk<br />
• Prostate cancer is the most common<br />
cancer in UK men, with 30,000 new<br />
cases diagnosed each year.<br />
• As many as 80% of men develop<br />
prostate cancer during their<br />
lifetime, but in most cases it does<br />
not cause any ill health. Around<br />
6% of men experience symptoms of<br />
the disease, while 3% of men die<br />
of prostate cancer.<br />
• Screening for prostate cancer<br />
using the Prostate Specific<br />
Antigen (PSA) blood test remains<br />
very controversial but, for<br />
better or worse, PSA testing of<br />
healthy men is increasing.<br />
• <strong>The</strong> first randomised trial<br />
comparing surgery versus watchful<br />
waiting in men with prostate<br />
cancer, reported in <strong>2005</strong>, showed<br />
a 5% survival advantage for<br />
surgery but with a 28% risk of<br />
urinary incontinence and<br />
a 35% risk of impotence.<br />
Active surveillance of early<br />
prostate cancer<br />
Most prostate cancers will never<br />
cause any problems and do not need<br />
any treatment. On the other hand,<br />
some prostate cancers will grow and<br />
spread, and become life threatening.<br />
Unfortunately, it can be difficult to<br />
distinguish between these two<br />
types of the disease. One solution is<br />
to treat all cases, ‘to be on the safe<br />
side’. However, while curative<br />
treatment for prostate cancer may<br />
or may not improve a man’s<br />
longevity, it can certainly have a<br />
big impact on his lifestyle with<br />
side-effects including impotence and<br />
incontinence. Ideally, treatment<br />
should be restricted to those who<br />
need it. Active surveillance aims<br />
to individualise the management of<br />
early prostate cancer by selecting<br />
only those men with significant<br />
cancers for curative treatment.<br />
Patients on active surveillance<br />
are closely monitored using<br />
PSA blood tests and repeat<br />
prostate biopsies. <strong>The</strong> choice<br />
between continued observation<br />
and curative treatment is<br />
based on evidence of disease<br />
progression during this<br />
monitoring.<br />
Studies at the <strong>Royal</strong> <strong>Marsden</strong><br />
In 2002, we began a prospective<br />
study of active surveillance of<br />
prostate cancer at the <strong>Royal</strong> <strong>Marsden</strong>.<br />
This initiative, funded by the<br />
National Cancer <strong>Research</strong> Institute<br />
Southern Prostate Cancer<br />
Collaborative, has grown to become<br />
the largest study of its kind and<br />
has already recruited over 300 men<br />
with prostate cancer. Currently,<br />

Figure 1. Diffusion-weighted magnetic resonance imaging (DW-MRI) provides image contrast through measurement of the diffusion properties<br />
of water within tissues. <strong>The</strong> white arrow indicates an area of abnormal water diffusion within the prostate gland. It is possible that DW-MRI<br />
may provide a better indication of prostate cancer behaviour than conventional MRI techniques.<br />
around 20% of these men have<br />
received curative treatment, while<br />
the rest have continued on<br />
observation. None of these patients<br />
have developed any symptoms from<br />
prostate cancer, or any spread of the<br />
disease, and none have died of<br />
prostate cancer. <strong>The</strong>se preliminary<br />
results are most encouraging and<br />
have established the feasibility of<br />
active surveillance for men with<br />
localised prostate cancer.<br />
<strong>The</strong> initial findings from the<br />
<strong>Marsden</strong> active surveillance study<br />
suggest that the size of a man’s<br />
prostate gland may be more<br />
important than had previously been<br />
appreciated. As men get older, their<br />
prostate gland enlarges but the degree<br />
of enlargement can vary as much<br />
as 10-fold between individuals. We<br />
found that the ratio of the PSA<br />
level in the blood to the size of the<br />
prostate gland, which is known<br />
as the ‘PSA density’, is an important<br />
predictor of disease progression in<br />
men with prostate cancer undergoing<br />
active surveillance. If this finding<br />
were to be confirmed, it would<br />
provide one very simple way of<br />
helping to individualise treatment for<br />
men with localised prostate cancer.<br />
Those with a small prostate might be<br />
better suited to immediate curative<br />
treatment, while observation may be<br />
more appropriate for those with<br />
a larger prostate. However, there will<br />
always be exceptions to this general<br />
rule, and it remains vital to identify<br />
better predictors of individual<br />
prostate cancer behaviour.<br />
At present, repeat prostate biopsy is<br />
the gold standard method to identify<br />
tumour progression, and hence the<br />
need for treatment, in men on active<br />
surveillance. Prostate biopsy can<br />
be uncomfortable for patients, and<br />
also carries risks of bleeding and<br />
infection. In collaboration with Dr<br />
Nandita deSouza (Cancer <strong>Research</strong><br />
UK Clinical Magnetic Resonance<br />
<strong>Research</strong> Group at <strong>The</strong> Institute), we<br />
are evaluating novel magnetic<br />
resonance techniques in men on<br />
active surveillance to see whether<br />
they can provide a non-invasive<br />
indicator of tumour progression<br />
(see article by Professor Martin Leach<br />
and Dr Nandita deSouza, p.34).<br />
Another trial (designated Prostate<br />
START) is due to open at the <strong>Royal</strong><br />
<strong>Marsden</strong> during 2006. Prostate START<br />
is an international, multicentre study<br />
that will compare active surveillance<br />
against standard curative treatment<br />
for prostate cancer in 2,000 men. <strong>The</strong><br />
main endpoint of the trial, to be coordinated<br />
at <strong>The</strong> Institute's Clinical<br />
Trials Unit (UK Principal Investigator:<br />
Cr Chris Parker), is long-term survival.<br />
It is hoped that active<br />
surveillance will avoid<br />
‘unnecessary’ treatment,<br />
and its associated sideeffects,<br />
without detriment<br />
to long-term survival.<br />
Psychological impacts of<br />
active surveillance<br />
One concern about active surveillance<br />
is that men may find it difficult to<br />
deal with the knowledge that they<br />
have a cancer that is not being<br />
treated. Dr Maggie Watson and Miss<br />
Katrina Burnet, from the Psychology<br />
<strong>Research</strong> Group at <strong>The</strong> Institute,<br />
are evaluating the prevalence<br />
of anxiety and depression in men<br />
on active surveillance, in order<br />
to better understand the underlying<br />
52
RADIOTHERAPY – PROSTATE CANCER<br />
psychological factors. <strong>The</strong>ir initial<br />
findings are reassuring. It appears<br />
that men on active surveillance<br />
for prostate cancer are no more<br />
anxious than those receiving<br />
active treatment, or indeed than<br />
UK cancer doctors!<br />
enables many candidate biomarkers<br />
to be evaluated rapidly and makes<br />
highly efficient use of the small<br />
amounts of prostate tissue available.<br />
Dr Jhavar is now studying biopsies<br />
from the active surveillance patients<br />
in this way in order to identify which<br />
pattern of markers best predicts<br />
prostate cancer behaviour.<br />
surgically excised. Several nutritional<br />
factors have been implicated in the<br />
development and progression of<br />
prostate cancer. For example, initial<br />
studies have suggested that<br />
supplements containing selenium,<br />
vitamin E or vitamin D may reduce<br />
the risk of the disease.<br />
Active surveillance provides<br />
an excellent opportunity for<br />
research to identify markers<br />
of prostate cancer behaviour.<br />
Markers of prostate<br />
cancer behaviour<br />
Men taking part in the <strong>Royal</strong> <strong>Marsden</strong><br />
study have given samples of blood,<br />
urine and prostate tissue for research.<br />
<strong>The</strong>se samples are uniquely valuable<br />
because, unlike samples in any other<br />
prostate tissue bank, they are linked<br />
to information on the natural history<br />
of each individual cancer. <strong>The</strong>y are<br />
now being used in a range of<br />
studies, both within <strong>The</strong> Institute of<br />
Cancer <strong>Research</strong> and elsewhere, to<br />
evaluate prostate cancer biomarkers.<br />
For example, Dr Sameer Jhavar,<br />
working in Professor Colin Cooper’s<br />
laboratory at <strong>The</strong> Institute, has<br />
devised a new technique that allows<br />
prostate biopsy tissue to be used<br />
to make microarrays. This technique<br />
Accurate prediction of<br />
individual prostate cancer<br />
behaviour will be invaluable<br />
in helping to decide<br />
which men need treatment<br />
and which do not.<br />
<strong>The</strong> future of active<br />
surveillance<br />
In the future, active surveillance<br />
could be the setting for trials to test<br />
low-toxicity interventions designed<br />
not to eradicate the disease but<br />
rather to alter its natural history. At<br />
present, using regular PSA testing<br />
in healthy men, it is possible to<br />
diagnose prostate cancer 10-15 years<br />
before it would cause any symptoms.<br />
A well-tolerated intervention that<br />
slowed the rate of progression still<br />
further could turn prostate cancer<br />
into a chronic condition to be<br />
controlled, rather than a disease to be<br />
We plan to study the effect<br />
of nutritional supplements on<br />
the rate of disease progression<br />
in men with localised prostate<br />
cancer on active surveillance.<br />
In summary, active surveillance is an<br />
attractive and increasingly popular<br />
approach to the management of early<br />
prostate cancer. It is also an ideal<br />
setting for research to identify new<br />
markers of prostate cancer behaviour.<br />
Such markers could transform our<br />
ability to target treatment to those<br />
who need it. A long-term hope is<br />
that nutritional intervention studies<br />
in men on active surveillance could<br />
lead to a whole new way of managing<br />
prostate cancer, aimed at disease<br />
control rather than cure. This would<br />
be a major step forward because<br />
it would avoid the burden of adverse<br />
effects such as impotence that<br />
are associated with conventional<br />
surgical treatment.<br />

HEALTH RESEARCH - CANCER CARE<br />
THE SEPSIS SYNDROME<br />
In order to understand the challenges of diagnosis, and the lack<br />
of progress in reducing mortality rates, it is important to understand<br />
the basic mechanisms and pathophysiology of the sepsis syndrome.<br />

Sepsis susceptibility<br />
Sepsis is a leading cause of death<br />
across the world and the commonest<br />
cause of death in non-coronary<br />
intensive care units worldwide. <strong>The</strong><br />
documented incidence of sepsis cases<br />
per annum worldwide is 1.8 million<br />
but there are considerable problems<br />
with diagnosis and monitoring<br />
in many countries, and this figure<br />
is therefore likely to be an underestimation.<br />
In fact it is likely that<br />
the number of cases per annum<br />
may reach 18 million corresponding<br />
to an incidence of 3 in 1000. <strong>The</strong><br />
mortality rate is generally between<br />
30-70% though it can be higher in<br />
a person with a pre-existing disease.<br />
As the older population is<br />
increasing, and the elderly are both<br />
more susceptible to sepsis and<br />
have a higher associated mortality,<br />
it is predicted that incidence<br />
and mortality will continue to grow.<br />
Other influences on incidence are<br />
likely to be factors such as the increase<br />
in nosocomial infections and higher<br />
rates of antimicrobial resistance.<br />
Pathophysiology of the<br />
sepsis syndrome<br />
<strong>The</strong> sepsis syndrome is a complex<br />
systemic inflammatory condition<br />
associated with infection. It is<br />
not the infective pathogen that<br />
directly causes the sepsis syndrome<br />
and corresponding high mortality<br />
associated with severe sepsis but<br />
the host response to that pathogen. To<br />
appreciate the current understanding<br />
of the syndrome it is useful to divide<br />
the complicated pathophysiology into<br />
four main areas:<br />
• <strong>The</strong> individual host response<br />
• <strong>The</strong> role of the endothelium<br />
(lining of blood vessel)<br />
• <strong>The</strong> disequilibrium of the<br />
pro-inflammatory and antiinflammatory<br />
mechanisms<br />
• Activation of the coagulation<br />
pathways<br />
Following invasion of bacteria, local<br />
endothelial cells cause the release<br />
of inflammatory mediators and the<br />
activation of the clotting cascade.<br />
This endothelial action is a part of<br />
the normal healthy response of<br />
the body to an invading pathogen.<br />
In severe sepsis, however, the<br />
endothelial response is no longer a<br />
healthy response but a dysfunctional<br />
one where, rather than local<br />
measured activity, there is an<br />
excessive, sustained and generalised<br />
activation of the endothelium.<br />
This generalised host response can<br />
no longer be regulated by local<br />
negative feedback mechanisms and<br />
results in a severe disequilibrium<br />
of inflammatory response, which<br />
causes generalised tissue injury,<br />
vascular permeability, shock and<br />
multi-organ failure.<br />

Table 1. <strong>The</strong> risks of infection and sepsis for cancer patients<br />
Characteristic<br />
Reason for greater risk of sepsis<br />
Repeated hospitalisation<br />
Increase in nosocomial (hospital-acquired) infections<br />
Repeated invasive therapy utilising shortor<br />
long-term central venous access devices (CVAD)<br />
Increased exposure to CVAD-associated infections<br />
Bone marrow suppression because of disease<br />
infiltration of the marrow (eg, in liquid cancers or<br />
metastatic disease involving the bone)<br />
Bone marrow suppression results in pancytopaenia<br />
with a resultant lowering of white cell count, platelet<br />
count and red cell count. <strong>The</strong> white cells are the<br />
body’s first and most important response to infection<br />
Bone marrow suppression as a result of treatment<br />
(chemo/radiotherapy)<br />
<strong>The</strong> resultant neutropenia (reduction in the<br />
absolute neutrophil count) renders the body exquisitely<br />
susceptible to infections<br />
Malnutrition associated with disease or treatment<br />
Poor immunity and resistance to infection<br />
A predominantly older population who are more likely<br />
to have co-morbid conditions<br />
Generally frail health means more likely to be<br />
less resistant to infections<br />
Increased exposure to transfused blood and its<br />
components either as a result of repeated surgery<br />
or the disease and chemo/radiotherapy<br />
<strong>The</strong> transfusion of donated blood and its components,<br />
such as platelets, clotting factors and fibrinogen,<br />
carries the risk of transmitting donor infections<br />
<strong>The</strong>re is a heterogeneity of<br />
response depending on several<br />
individual host factors such<br />
as age, genetics, any pre-existing<br />
disease, gender, the type of<br />
pathogen and the area of the<br />
body most affected.<br />
Sepsis and cancer<br />
All cancer patients are very<br />
susceptible to sepsis and its associated<br />
symptoms for many reasons (see<br />
Table 1). Patients suffering from types<br />
of cancer where the bone marrow<br />
is diseased, such as leukaemia,<br />
lymphoma and myeloma, are more<br />
vulnerable to sepsis as these cancers<br />
directly affect the body’s immune<br />
response. <strong>The</strong> definitive treatment for<br />
these ‘liquid cancers’ is marrow<br />
ablative chemotherapy which is<br />
where a patient’s bone marrow<br />
is destroyed before replacing it with<br />
allogeneic (from another person)<br />
or autologous (from self) stem cells<br />
or bone marrow. <strong>The</strong>re are also<br />
some cancer patients with solid<br />
tumours (eg, teratoma) who<br />
may need to receive the same<br />
marrow ablative chemotherapy.<br />
<strong>The</strong> mortality rate for cancer<br />
patients who develop sepsis and<br />
then severe sepsis is quoted as<br />
being 65 to 85%, and is the<br />
major reason for bone marrow<br />
transplant-associated deaths in<br />
the first six weeks of therapy.<br />
Diagnosis of sepsis<br />
<strong>The</strong> early diagnosis of patients with<br />
sepsis has been shown to reduce<br />
mortality rates. It allows prompt<br />
treatment with antibiotics and also,<br />
where possible, for the removal of the<br />
sepsis source. For example, surgical<br />
intervention to remove a portion of<br />
gangrenous gut, or the removal of a<br />
skin tunnelled catheter in people with<br />
cancer, can be performed.<br />
<strong>The</strong> difficulty for all nurses and<br />
healthcare teams is that the early<br />
indications may be subtle and<br />
difficult to recognise. It is also<br />
the case that some of the clinical,<br />
biochemical and haematological<br />
signs of sepsis are also indicators<br />
of non-sepsis conditions such as<br />
pancreatitis, cerebral haemorrhage<br />
or other major shock conditions.<br />
Much work over the last 10 years<br />
has been concentrated on the early<br />
recognition and subsequent early<br />
therapy for sepsis in an attempt to<br />
prevent the systemic symptoms of<br />
generalised inflammatory change,<br />
tissue damage, increased cell<br />
permeability, shock and organ damage.<br />

HEALTH RESEARCH - CANCER CARE<br />
If we can identify patients early<br />
and monitor them closely, we may<br />
be able to prevent critical illness and<br />
reduce the high sepsis mortality rates<br />
especially in people with cancer.<br />
As nurses work so intimately with<br />
people who are at the highest<br />
risk of developing sepsis, they<br />
are key members of the<br />
multidisciplinary team.<br />
A study has been designed<br />
to help nurses to identify at-risk<br />
patients, and patients who are<br />
deteriorating rapidly. <strong>The</strong> study<br />
aims to increase knowledge<br />
of the sepsis syndrome, translate<br />
that knowledge into action,<br />
and reduce the vulnerability<br />
of the person with cancer.<br />
Early diagnosis of<br />
sepsis study<br />
<strong>The</strong>re are several subtle early<br />
indicators of sepsis in a patient that<br />
the nurses in this study will explore.<br />
<strong>The</strong>re are also a range of indicators in<br />
the patient’s blood such as a rise in<br />
white blood cells, a rise in C-reactive<br />
protein (CRP) and several other<br />
inflammatory markers that can be<br />
measured in the laboratory.<br />
<strong>The</strong> overall aims of the study are to:<br />
• Improve the awareness of the<br />
sepsis syndrome across <strong>The</strong> <strong>Royal</strong><br />
<strong>Marsden</strong> NHS Foundation Trust and<br />
the imperative for early diagnosis<br />
• Strengthen the clinical<br />
assessment package<br />
• Decrease any delay in treating<br />
the patient<br />
• Determine the feasibility of using<br />
a bedside blood test, PCT-Q, as part<br />
of the clinical assessment package.<br />
<strong>The</strong> key interventions that are being<br />
tested in this prospective trial are:<br />
a) dedicated ward teaching sessions<br />
to 200 nurses across the Trust on<br />
the sepsis syndrome, and its early<br />
diagnosis and treatment; and b)<br />
the feasibility of ward-based nurses<br />
using a bedside test (PCT-Q) which<br />
measures the level of the marker<br />
procalcitonin (PCT).<br />
PCT-Q is an easy to use blood testing<br />
kit (see Figure 1) that measures the<br />
level of procalcitonin in the blood<br />
within 30 minutes and gives a semiquantifiable<br />
index of the severity<br />
of the sepsis. Procalcitonin, the prohormone<br />
of calcitonin, was first<br />
discovered in 1961 and shown to be<br />
involved in lowering serum calcium.<br />
However, following a meningitis<br />
outbreak and a case of staphylococcal<br />
toxic shock syndrome in 1983, its role<br />
in sepsis has been studied. In over<br />
1,200 studies conducted from the<br />
1990s to the present, procalcitonin<br />
has been shown to be a more reliable<br />
and specific early indicator of sepsis<br />
than other indicators such as CRP.<br />

Time (h)<br />
Procalcitonin rapidly rises as a<br />
response to sepsis and then stays<br />
high in the blood for 24-48 hours<br />
(see Figure 2).<br />
In 2003 a bedside test called<br />
PCT-Q became available<br />
allowing the rapid measurement<br />
of procalcitonin, a marker for<br />
sepsis.<br />
Although PCT-Q has been used<br />
previously in small populations,<br />
this is the first time it will have<br />
been used in a large sample (570<br />
patient episodes) and by ward-based<br />
nurses. Nurse and patient accrual<br />
is now complete and the data<br />
are being analysed.<br />
Early analysis of the study<br />
has revealed that correlations<br />
between PCT levels and<br />
the onset of sepsis and severe<br />
sepsis are highly statistically<br />
significant. In over 500 episodes<br />
of neutropenic and nonneutropenic<br />
sepsis, PCT levels<br />
were more accurate in predicting<br />
sepsis than those of CRP.<br />
Qualitative data analysis from<br />
interviews with the nurse participants<br />
revealed some valuable data regarding<br />
early detection of sepsis in cancer<br />
patients. Nurses who have regular<br />
contact with their patients are able<br />
to recognise subtle changes in<br />
demeanour, behaviour or appearance.<br />
This is a prompt for further<br />
examination and leads to discovery<br />
of changes in the patient’s vital signs<br />
or blood tests that may indicate sepsis.<br />
<strong>The</strong> conclusions of this study<br />
indicate that it is not only skilled<br />
nursing but also, crucially, its<br />
continuity which are important<br />
to the early detection and<br />
treatment of sepsis.<br />

RADIOTHERAPY – TAILORED TREATMENT<br />
DOSIMETRY FOR TARGETED<br />
RADIONUCLIDE THERAPY<br />
Combined advances in molecular imaging and radionuclide therapy<br />
have major implications in the move towards tailored cancer treatment.<br />

Foundation Trust<br />
Introduction to targeted<br />
radionuclide therapy<br />
Targeted radionuclide therapy (TRT)<br />
kills cancer cells by delivering a lethal<br />
dose of radiation. <strong>The</strong> radiation<br />
is usually attached to a ‘carrier’ that<br />
selectively seeks out tumour cells.<br />
As with external beam radiotherapy,<br />
TRT offers the advantage of<br />
delivering high radiation doses to<br />
a specific target but in common<br />
with chemotherapy it can deliver<br />
treatment systemically, attacking<br />
multiple sites throughout the body.<br />
It is a relatively benign treatment<br />
that does not incur the side-effects,<br />
such as hair loss and prolonged<br />
nausea, often seen in more<br />
conventional treatments.<br />
How radiation works for<br />
cancer management<br />
When a radioactive atom decays,<br />
one or more of a number of particles<br />
are emitted. Beta particles act<br />
like small billiard balls, travelling<br />
only short distances in the body<br />
until hitting nearby cells and killing<br />
or damaging them. It is these<br />
particles that are mainly responsible<br />
for delivering radionuclide treatment.<br />
Since the radioactivity is constantly<br />

Figure 1. <strong>The</strong> use of radiation for cancer treatment in TRT:<br />
A radioactive atom decays (1) and emits both<br />
gamma rays (2) and beta particles (5).<br />
<strong>The</strong> gamma rays are imaged by a scintillation<br />
camera (3) to produce functional images (4).<br />
<strong>The</strong> beta particles hit nearby cells (6),<br />
damaging or killing them.<br />
58
RADIOTHERAPY – TAILORED TREATMENT<br />
decaying, the success of a treatment<br />
is dependent on the amount of<br />
radioactivity that is taken up in a<br />
tumour and how long it remains<br />
localised. With many radioisotopes<br />
used in TRT, gamma rays are also<br />
emitted. <strong>The</strong>se rays are simply high<br />
energy light that is invisible to<br />
the naked eye but imageable by the<br />
specially designed scintillation<br />
cameras which are used in nuclear<br />
medicine. It is therefore possible to<br />
simultaneously administer treatment<br />
and to see the radiation that delivers<br />
the treatment in vivo (see Figure 1).<br />
Dosimetry for patientspecific<br />
treatment planning<br />
Until recently, TRT has been<br />
delivered either with fixed levels of<br />
activity or, more rarely, according<br />
to the patient’s weight. <strong>The</strong> increasing<br />
use of molecular imaging is<br />
changing the basic approach to<br />
treatment planning for TRT<br />
since it is now possible to take into<br />
account the patient’s specific<br />
biokinetics to determine how their<br />
treatment could be tailored. Images<br />
obtained after administration can<br />
be used to monitor where the<br />
radiation is taken up within a patient.<br />
It has been shown that if two<br />
patients are given the same amount<br />
of radioactivity, there can be a<br />
substantial variation in the quantity<br />
of radiation that is taken up in<br />
a tumour or in a normal organ, and<br />
in the time that the radiation<br />
remains there.<br />
Our research is focused<br />
on measuring radiation<br />
‘uptake and retention’<br />
characteristics of tumours<br />
and normal organs, with<br />
the aim of tailoring treatment<br />
to individual patients.<br />
For example, where a patient has<br />
relatively little radioactivity taken<br />
up in tumour tissue, or if they lose<br />
the radioactivity quickly, higher<br />
activities can be safely administered<br />
to ensure that the patient receives<br />
the prescribed radiation absorbed<br />
dose. <strong>The</strong> measurement techniques<br />
are also applied to normal organs<br />
that could be adversely affected,<br />
such as the bone marrow, liver or<br />
kidneys, to ensure that these do<br />
not receive too high an absorbed<br />
dose. <strong>The</strong> practice of studying<br />
the distribution of radiation in<br />
individual patients in this way<br />
is termed ‘dosimetry’.<br />
TRT:<br />
A multidisciplinary approach<br />
Whilst the use of relatively small<br />
quantities of radiopharmaceuticals<br />
for diagnostic imaging has been<br />
a mainstay of cancer management<br />
for many decades, TRT has remained<br />
a little-used method of cancer<br />
treatment, in part because of<br />
its complexity and the need for<br />
a multidisciplinary approach.<br />
To successfully apply patient-specific<br />
treatment it is necessary to have<br />
a team comprising clinical and<br />
medical oncologists, nuclear<br />
medicine physicians, specialist nurses,<br />
radiographers and physicists.<br />
Together the <strong>Royal</strong> <strong>Marsden</strong> and <strong>The</strong><br />
Institute form one of only a very<br />
few cancer centres in Europe that are<br />
able to do this. Advances are being<br />
made in this field supported by grants<br />
from a number of funding bodies,<br />
including the Neuroblastoma Society,<br />
Cancer <strong>Research</strong> UK and the<br />
European Union. New methods<br />
devised to calculate uptake and<br />
retention characteristics from the<br />
images have been made possible<br />
by the increase in computing power<br />
over recent years and we enjoy close<br />
collaborations between specialist<br />
centres in Europe and the US.<br />
Translational research<br />
<strong>The</strong> Radioisotope Physics Team in<br />
the <strong>Joint</strong> Department of Physics<br />
comprises both research and clinical<br />
scientists. Basic research is being<br />
conducted into problems such as<br />
computer and mathematical<br />
modelling of the scintillation cameras<br />
(SPECT and PET/CT) and of the<br />
interactions of radiation in tissue,<br />
with results that may be subsequently<br />
applied to a range of imaging studies<br />
or treatments. Recently, the optimal<br />
method for bremstrahlung imaging of<br />
pure beta emitting radionuclides such<br />
as 32-Phosphorus and 90-Yttrium has<br />
been determined, and modelling<br />
studies have been conducted to see<br />
whether calculated radiation doses<br />
can be translated directly into<br />
survival probabilities for cancer or<br />
normal cells.<br />
One major problem to overcome in<br />
dosimetry for TRT is that at present<br />
there are no internationally accepted<br />
standard methods to calculate<br />
radiation doses. To address this, an<br />
extensive study of error propagation<br />
is being carried out to determine<br />
the uncertainties inherent in the<br />
various methods of dosimetry<br />
that are used in different centres,<br />
and radiation-sensitive polymer<br />
gels are being used to verify dosimetry<br />
techniques. This will facilitate<br />
multi-centre trials whereby results<br />
obtained at different centres<br />
may be directly compared.<br />
In conjunction with<br />
basic research, this new<br />
methodology is being<br />
applied to a range of clinical<br />
treatments with established<br />
and newly developed<br />
radiopharmaceuticals.<br />

RADIOTHERAPY – TAILORED TREATMENT<br />
131-Iodine mIBG for<br />
neuroblastoma (with Dr Frank<br />
Saran, Dr Donna Lancaster,<br />
Professor Andy Pearson)<br />
Neuroblastoma is a childhood cancer<br />
of neural crest cells. In 50% of cases<br />
it has metastasised by the time of<br />
diagnosis with a 5-year survival<br />
rate of only 30-40%.<br />
In conjunction with<br />
University College Hospital,<br />
we are leading a new European<br />
study to use 131-Iodine mIBG<br />
to treat patients that have<br />
relapsed after chemotherapy<br />
treatment. mIBG is a<br />
noradrenaline analogue<br />
that specifically targets<br />
neuroendocrine cells.<br />
In this study, the first of its kind,<br />
the quantity of radiation given is<br />
calculated based on the patient’s<br />
individual whole-body uptake and<br />
retention. Activity is administered<br />
in two fractions, spaced two weeks<br />
apart, with the aim of delivering<br />
a total whole-body absorbed dose of<br />
4 Gy. <strong>The</strong> activity for the first<br />
fraction is calculated from a weightbased<br />
formula whilst the activity<br />
for the second is calculated from<br />
measurements obtained from the<br />
first treatment so that a higher or<br />
lower activity is given as required.<br />
To date, the total activities<br />
administered have been within 10%<br />
of the target, ensuring that patients<br />
therefore receive a similar treatment.<br />
In some cases this has resulted in<br />
administered activities that are up to<br />
4 times higher than those routinely<br />
given, and initial evidence indicates<br />
that the increased administration<br />
results in higher tumour doses.<br />
This procedure has already yielded<br />
promising results (see Figure 2).<br />
186-Rhenium HEDP for bone<br />
metastases from prostate cancer<br />
(with Professor David<br />
Dearnaley, Dr Val Lewington)<br />
A study has recently been completed<br />
to calculate radiation doses from<br />
high activity treatment of bone<br />
metastases from prostate cancer. We<br />
have formulated a method to<br />
successfully predict patient-specific<br />
whole-body absorbed doses that<br />
would be delivered to a patient in<br />
advance of the treatment, based<br />
on routine clinical measurements<br />
such as kidney function and levels<br />
of alkaline phosphatase. A new<br />
study will target bone metastases<br />

measurements. This gamma camera scan taken before treatment<br />
clearly shows metastases in the bone marrow.<br />

she was attended by nurses and family. She suffered no sickness or<br />

131-Iodine sodium iodide for<br />
thyroid cancer (with Dr Clive<br />
Harmer, Dr Masud Haq, Dr Chris<br />
Nutting, Dr Val Lewington)<br />
131-Iodine sodium iodide is the most<br />
established treatment using TRT and,<br />
in combination with surgery, has a<br />
relatively high response rate. Although<br />
patients are usually given standard<br />
quantities of radiation, some remain at<br />
high risk. A dosimetry-based approach<br />
to treatment for patients identified as<br />
high-risk has been started, and a<br />
further study is being conducted<br />
to determine the absorbed dose to<br />
salivary glands during treatment since<br />
salivary dysfunction is a common<br />
side-effect of high activity treatment.<br />
Adult neuroendocrine tumours<br />
(with Dr Val Lewington,<br />
Dr Diana Tait)<br />
Dosimetry studies have<br />
determined that radiation doses<br />
delivered to tumours from standard<br />
administrations can range from 10 Gy<br />
to 120 Gy. As with neuroblastoma,<br />
adult neuroendocrine tumours have<br />
been treated here with 131-Iodine<br />
mIBG according to patient-specific<br />
whole-body uptake measurements,<br />
thereby maximising administered<br />
activities whilst keeping doses to<br />
normal organs such as the liver to a<br />
safe level. A promising treatment now<br />
underway targets cell surface<br />
neuroreceptors found in 90% of these<br />
tumours with neuropeptides<br />
radiolabelled with 90-Yttrium.<br />
32-Phosphorus for<br />
craniopharyngioma<br />
(with Dr Frank Saran)<br />
Craniopharyngioma is a disease<br />
often seen in paediatrics that results<br />
in the formation of large cysts in the<br />
brain. We are commencing a new<br />
study to use image-based dosimetry<br />
to direct the use of 32-Phosphorus<br />
injected directly into the cyst.<br />
Treatment is planned from initial<br />
scans acquired with a tracer quantity<br />
of 99m-Technetium to determine the<br />
quantity of radiation to inject.<br />
<strong>The</strong> future<br />
TRT is increasing rapidly in<br />
terms of the numbers of patients<br />
and the range of cancers treated.<br />
Individualised image-based treatment<br />
promises dramatic benefits. As the<br />
potential of dosimetry-based TRT is<br />
realised it is likely that this treatment<br />
will be more commonly used at<br />
an earlier stage in the patient’s<br />
treatment, rather than in later stage<br />
patients as is currently often the case,<br />
and that it will be increasingly used<br />
in conjunction with chemotherapy<br />
and radiotherapy to provide<br />
synergistic treatment. For example,<br />
in one project carried out in<br />
collaboration with Dr Phil Evans<br />
(Radiotherapy Physics <strong>Research</strong> Team<br />
at <strong>The</strong> Institute), it was shown that<br />
external beam radiotherapy could be<br />
planned taking into account the<br />
absorbed dose distribution delivered<br />
from the TRT. <strong>The</strong> advantage of this<br />
approach would be that whilst both<br />
types of radiotherapy treat the same<br />
volume, each has a different doselimiting<br />
factor: the absorbed dose to<br />
the adjacent tissue in the case<br />
of external beam radiotherapy; and<br />
frequently the red marrow in the<br />
case of TRT (see Figure 3). In tandem<br />
with the developments in TRT,<br />
there is an increasing interest in<br />
molecular imaging, particularly<br />
with PET/CT that enables the study<br />
of biological processes at the<br />
cellular and molecular level.<br />
<strong>The</strong>se imaging techniques are<br />
being increasingly used to examine<br />
the pharmacokinetics and<br />
pharmacodynamics of new drugs.<br />
An exciting area of research that<br />
could now be developed is to adapt<br />
methods for quantitative imaging and<br />
dosimetry and apply them to other<br />
drugs which can be radiolabelled.<br />
Image quantification<br />
and dosimetry will aid<br />
interpretation and<br />
understanding of the images<br />
acquired from new drugs<br />
or radiopharmaceuticals and,<br />
by administering them<br />
on a patient-specific basis,<br />
will help to fully realise<br />
their potential efficacy.<br />
