NCCS Scientists and Oncologists specialising in the research<br />

and treatment of lung cancer turned out in full force at the<br />

Singhealth – Duke-NUS Scientific Congress to give insightful<br />

updates about the top killer disease. VERONICA LEE reports.<br />

Proposal to ban tobacco products<br />

Perhaps one of the more engaging<br />

presentations that benefited not only the<br />

healthcare professionals but the public as<br />

well was Prof Koong Heng Nung’s proposal<br />

to deny the use of tobacco products for<br />

<strong>Singapore</strong> citizens born in or after the year<br />

2000. The Senior Consultant and Head of<br />

NCCS Department of Surgical Oncology<br />

enumerated the benefits and implications of<br />

his proposal before an attentive audience.<br />

Despite several effective campaigns and<br />

measures that have brought down smoking<br />

prevalence rates from 20% in 1984 to<br />

13.6% in 2007, the number of smokers<br />

between the ages of 12 and 18 has increased significantly. This was mirrored by the<br />

worldwide trend where smokers picked up the habit in their teenage years and this<br />

continued in their adult life.<br />

Prof Koong highlighted the rite of passage that many have come to associate with<br />

smoking, an activity seen to be connected with maturity and adulthood. Many<br />

youngsters are under the false notion that smoking is synonymous with the coming of<br />

age and is an accepted practice for adults.<br />

Although such a proposal may mean limiting one’s freedom, only less<br />

than 11% of the total population surveyed in the <strong>Singapore</strong> Lung<br />

<strong>Cancer</strong> Awareness Study 2007 felt that the proposal impinged on<br />

personal rights and freedom.<br />

Current laws make it difficult for cigarette<br />

vendors who have to do a mental<br />

calculation of the birth rates to ascertain<br />

whether or not the buyer is under-aged.<br />

Given this difficulty, Prof Koong proposed<br />

that a tobacco ban based on a fixed birth<br />

year would be easier to enforce.<br />

Although such a proposal may mean<br />

limiting one’s freedom, only less<br />

than 11% of the total population<br />

surveyed in the <strong>Singapore</strong> Lung <strong>Cancer</strong><br />

Awareness Study 2007 felt that the<br />

proposal impinged on personal rights<br />

and freedom.<br />

The proposal also aimed to minimise<br />

immediate hardship to the tobacco<br />

industry in that smokers who were of the<br />

legal age could still continue smoking<br />

and slowly phase out tobacco use without<br />

a sudden ban which was impractical<br />

given the economic repercussions of an<br />

immediate loss of excise revenues. This<br />

thus fulfils the industry’s assertion about<br />

not attracting new smokers.<br />

To Tobacco For Those Born<br />

Integrated Signature is valid<br />

in predicting clinical outcome<br />

for early stage lung cancer<br />

Traditionally, treatment for stage 1&2 Lung<br />

<strong>Cancer</strong> is surgery. This has been effective<br />

as the survival rate for patients after<br />

surgery is 40-50%. However, about 30%<br />

of survivors may suffer a relapse and die<br />

within five years. Hence there is the need<br />

to accurately identify patients who might<br />

benefit from adjuvant chemotherapy.<br />

However, Dr Patrick Tan, Principal<br />

Investigator, Division of Cellular and<br />

Molecular Research, who presented<br />

'Genetic Analysis of Lung <strong>Cancer</strong>' shared that the solution may not be as straight<br />

forward as it seemed. Findings from the CALGB 9633 trial had showed that while<br />

there was potential survival benefit for adjuvant chemotherapy in Stage 1B Lung<br />

<strong>Cancer</strong>, an update from the same trial showed no benefits.<br />

Dr Tan suggested that Stage 1B Non Small-Cell Lung <strong>Cancer</strong> (NSCLC) was thus ideal<br />

from which genomic strategies could be further researched, to classify patients with<br />

low and high risk of recurrence, with adjuvant therapy being a treatment option for<br />

high-risk patients.<br />

With one of the biggest challenge of NSCLC<br />

being chromosonal instability that contributes<br />

to inaccuracies in predicting tumour behaviour,<br />

Dr Tan highlighted that a prognostic signature<br />

solely based on gene expression may not<br />

be adequate. Rather, it is the integration of<br />

genomics and gene expression information, or<br />

what he called integrated signature, to derive<br />

a survival model rooted in recurrent CNAs<br />

associated with NSCLC that may be the best bet.<br />

Dr Tan however cautioned against specific<br />

genomic abnormalities which may be present<br />

among Asians and thus render western<br />

benchmarks irrelevant. Studies have shown that<br />

non-tobacco related risk factors exist and neversmokers<br />

constitute a portion of lung cancer<br />

patients, having been exposed to cooking<br />

fumes. Different tissue behaviour was also<br />

discovered between smoker and never-smokers.<br />

‘Genetic Analysis of<br />

Asian Lung <strong>Cancer</strong>s’<br />

(Dr Patrick Tan)<br />

Female Never-Smokers with<br />

East-Asian ethnic background<br />

have better chance of survival<br />

following chemotherapy<br />

Increasingly it has been found that<br />

people who do not smoke also suffer<br />

from lung cancer, suggesting that there<br />

are host differences in susceptibility to<br />

lung cancer and the presence of other<br />

risk factors. About 15% of men and 53%<br />

of women who do not smoke develop<br />

lung cancer, owing to their exposure to<br />

secondhand smoke, asbestos, radon and<br />

related substances, air pollution and<br />

smoke from cooking.<br />

However, the good news is that never-smokers with East Asian ethnicity and<br />

adenocarcinoma make-up are more likely to respond to treatment than their<br />

western counterparts. This was found in the recent clinical development of the<br />

epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs),<br />

gefitinib and erlotinib. Mutations in the EGFR kinase domain are more common<br />

and patients with these mutations have increased sensitivity to EGFR TKIs.<br />

Approximately 30-40% of NSCLC patients in<br />

Asia and 10-15% of Caucasians have EGFR<br />

mutation-positive tumours and over 70% of these<br />

patients are women in <strong>Singapore</strong>.<br />

Prof Hui Kam Man, Head of NCCS Division of<br />

Cellular and Molecular Research, presented these<br />

findings of the study, in which gene expression<br />

profiling to measure all the mRNA in the lung<br />

tumor tissues of these patients was carried out. The<br />

team has also identified gene signatures associated<br />

with better treatment responses to chemotherapy<br />

and prolonged survival for female never-smokers<br />

patients with adenocarcinoma of different ethnic<br />

backgrounds. Further molecular evidence was also<br />

presented to demonstrate that Chinese female neversmokers<br />

with adenocarcinoma is not a homogenous<br />

population and the responses to treatment could<br />

also differ within this group of patients.<br />

a Distinct Disease’<br />

Genomics techniques is useful<br />

in unraveling drug resistance<br />

About $1.2 million people suffer from<br />

lung cancer annually. Majority present<br />

in the advanced stage and even in<br />

those patients that undergo surgery,<br />

a significant proportion of cases<br />

eventually recur. Advanced stage lung<br />

cancer (Stage 3B and 4) is traditionally<br />

treated with chemotherapy, with<br />

response rates of approximately 20%<br />

with a median survival of six months.<br />

For the past three decades, selection<br />

of chemotherapy regimens for the<br />

treatment of NSCLC has largely been empirical. However, with the advent genomic<br />

technologies, there is now an improved understanding of the disease biology that<br />

has led to classifying lung cancer into molecular subtypes. Importantly, these<br />

subtypes are now amenable to targeted therapeutics, especially in the era of<br />

mechanism-based drug discovery. In the landmark IPASS study, in which NCCS<br />

was one of the participating sites, 1,217 patients were randomly allocated to<br />

either gefitinib (an EGFR tyrosine kinase inhibitor) or carboplatin-paclitaxel. In<br />

approximately two thirds of patients that harboured the EGFR mutation, response<br />

rates were 70%, and the overall median survival 22 months.<br />

Genomics techniques have also been useful in unravelling drug resistance<br />

mechanisms – the common reason for treatment failure. Elucidating these<br />

mechanisms allow the development of rational strategies to overcome them.<br />

A critical aspect is the need for discovering and developing new biological<br />

markers – or biomarkers – that can help in directing these treatments.<br />

However, Dr Daniel Tan, Associate Consultant, Department of <strong>Medical</strong> Oncology,<br />

NCCS warned that while identifying biomarkers that predict for drug response<br />

promise to improve cancer management, it is important that they undergo<br />

sufficient rigor to ensure their validity, reproducibility and repeatability. Indeed<br />

an inaccurate biomarker may be misleading – resulting in unnecessary patient<br />

exposure to ineffective drugs, or conversely patients wrongly deprived of useful<br />

treatments. A new generation of clinical trials is necessary to meet these evolving<br />

concepts of patient selection in targeted therapeutics.<br />

Dr Tan also shared that such translational studies are resource-intense, requiring<br />

multidisciplinary input involving oncologists, basic scientists, radiologists,<br />

pathologists as well as other disciplines. The crucial components of such an<br />

infrastructure are already available in NCCS and the Outram Campus, and the<br />

next few years hold tremendous promise for lung cancer patients.<br />

IMPROVING COSMETIC<br />

BREAST CANCER SURGERY<br />

SALUBRIS<br />

November / December 2010<br />

It is a sobering fact that <strong>Singapore</strong> has the highest rate of breast cancer in Asia.<br />

It is the commonest cancer among women here, with about 1300 new cases<br />

every year. Management of breast cancer remains challenging and requires a<br />

coordinated, multidisciplinary approach. Despite the continued discovery of<br />

newer and better pharmaceutical agents and improved delivery of radiotherapy,<br />

surgery still remains the cornerstone of breast cancer treatment.<br />

For most women, the diagnosis of breast cancer evokes intense feelings of<br />

fear, anxiety and despair. In addition, the breast is also a powerful emblem<br />

of womanhood. The thought of losing a breast accounts for much of the<br />

reluctance for a patient in undergoing surgery. Following treatment, there is also<br />

considerable long-term psychological impact on self-esteem and body image.<br />

Thankfully, with better understanding of the disease as well as improved surgical<br />

options and techniques, patients can achieve a good cosmetic outcome without<br />

compromising the chances of cure.<br />

By Dr Ong Kong Wee<br />

Consultant<br />

Department of Surgical Oncology<br />

NCCS<br />

Recently, a specialised field of breast cancer surgery termed oncoplastic surgery<br />

is gaining widespread popularity. This evolving area is based on the principles of<br />

surgical oncology as well as plastic and reconstructive surgery, and applies them to<br />

the management of breast cancer patients. It describes a surgical approach encompassing<br />

a wide range of surgical procedures, and not just one particular operation. The aims of<br />

oncoplastic surgery are to achieve wide enough surgical margins to reduce local recurrence<br />

yet optimise cosmetic outcome.<br />

Careful pre-operative planning is the first important step in oncoplastic surgery. In<br />

some cases, a magnetic resonance imaging (MRI) scan of the breasts may be required<br />

to determine the extent of the disease as well as exclude occult contra lateral cancer.<br />

Confirmation of the diagnosis by minimally invasive techniques is essential and allows the<br />

patient to have in-depth discussion with a multidisciplinary team including the surgical<br />

oncologist and plastic surgeon about her surgical options.<br />

Oncoplastic techniques can generally be classified according to whether part of, or the<br />

entire breast, is removed.<br />

When part of the breast is removed, the resulting defect can be filled by either a<br />

displacement or replacement flap. A displacement flap involves mobilising breast tissue<br />

from the same breast to minimise the resultant deformity. In other instances, particularly if<br />

the patient has small breasts, a replacement flap consisting of autologous tissue from other<br />

parts of the body, e.g. back muscles, is fashioned to achieve the desired cosmetic outcome.<br />

Autologous fat transfer has also been tried but is still in an early phase of development. A<br />

key advantage of partial breast surgery using oncoplastic techniques is that larger tumours<br />

can be resected safely compared with standard breast conservation surgery.<br />

Whole breast reconstruction following mastectomy is much more commonly practised<br />

locally. In this procedure, a mastectomy is carried through a small skin incision while<br />

preserving the overlying skin and in selected cases, including the nipple-areolar complex.<br />

The breast mound is then recreated immediately with a myocutaneous flap harvested from<br />

the abdomen or back. Alternatively, a prosthesis may be inserted in lieu of a flap.<br />

Although this procedure is time consuming<br />

and technically demanding, the risks and<br />

possible complications are minimised with<br />

modern surgical approaches.<br />

Current surgical techniques<br />

for breast cancer have<br />

improved by leaps and<br />

bounds, particular over the<br />

last 30 years. Achieving the<br />

twin aims of durable cure as<br />

well as excellent cosmetic<br />

outcome is an established<br />

reality with the techniques<br />

available today.

NCCS TEAM BAGS BEST<br />

POSTER AWARD<br />

FROM EUROPEAN SOCIETY<br />

FOR MEDICAL ONCOLOGISTS<br />

Researchers from the<br />

<strong>National</strong> <strong>Cancer</strong> <strong>Centre</strong><br />

<strong>Singapore</strong> (NCCS) receive<br />

recognition for their work<br />

on Nasopharyngeal <strong>Cancer</strong><br />

from the European Society<br />

For <strong>Medical</strong> Oncologists<br />

(ESMO). VERONICA LEE<br />

finds out more about their<br />

study on vaccines.<br />

Nasopharyngeal cancer (NPC) is<br />

a tumor that is relatively rare<br />

in the west, but common in<br />

<strong>Singapore</strong> and Southeast Asia. Although<br />

the cure rate for patients with early stage<br />

disease is good, patients with advanced<br />

stage disease where the cancer has spread<br />

to other organs, are incurable and have<br />

a poor outlook. Although Chemotherapy<br />

remains the only option for these patients,<br />

it seldom produces durable cancer<br />

control and the disease starts recurring<br />

once chemotherapy is stopped.<br />

The challenges in managing advanced NPC<br />

patients has prompted a team of doctors<br />

and scientists led by Dr Toh Han Chong<br />

and Dr John Chia from the NCCS <strong>Medical</strong><br />

Oncology Department to study novel ways<br />

of targeting the disease, in an attempt to<br />

improve outcomes for their patients.<br />

“NPC is a very interesting<br />

disease, in that it is driven by<br />

the Epstein-Barr virus which<br />

produces cancer causing<br />

proteins that drive cancer<br />

growth” says Dr John Chia, a<br />

Consultant <strong>Medical</strong> Oncologist.<br />

“Because these cancer proteins are also expressed on the surface of<br />

cancer cells, they also make the cancer cells vulnerable to recognition<br />

and killing by the immune system. Our project was to develop a vaccine<br />

that would boost the immune system’s ability to recognise these viral<br />

products on the cancer cells, and then to kill them.”<br />

The team thus began a clinical trial to test a “Dendritic Cell” (DC) vaccine against<br />

NPC in August 2007.<br />

The results of the study, which was carried out on 16 patients, showed that the DC<br />

vaccines that were administered to patients were able to potently activate and train the<br />

patients’ own immune cells to recognise and kill cancer. However, although the results<br />

were promising with no side effects, treatment was not sufficiently potent to cause<br />

eradication of the tumor in most patients.<br />

“The results seemed to indicate that our strategy in targeting the immune system is<br />

feasible and has given us many clues as to how the immune system works in cancer.<br />

But the treatment is not yet ready for prime time.” says Dr John Chia. “Our focus now<br />

is to try to make the vaccine better. We are exploring ways to modify the vaccine and<br />

explore strategies on combining the vaccine with other potent immune targeting cells.<br />

Along this line of research, we have just completed another trial involving the transfer of<br />

large numbers of highly active immune cells derived from patients’ own blood that have<br />

been trained to target and kill nasopharyngeal cancer cells. We are currently analysing<br />

the data and are encouraged by what we have seen so far”.<br />

The study “A Phase 2 study of vaccination with Adenovirus ΔLMP1-LMP2 transduced<br />

dendritic cells in patients with advanced metastatic nasopharyngeal carcinoma” was<br />

a group effort by Dr John Chia, Who-Whong Wang, Dr Marissa Teo, Wai Meng Tai,<br />

Dr Lim Wan Teck, Dr Tan Eng Huat, Dr Leong Swan Swan, Li Sun, Jian Jiun Chen,<br />

Stephen Gottschalk and Dr Toh Han Chong. The team was conferred the Best Poster<br />

(Head and Neck <strong>Cancer</strong>s) by ESMO.


STEREOTACTIC BODY<br />

RADIOTHERAPY<br />

November / December 2010<br />

It is well recognised that radiation therapy plays a<br />

key role in the treatment of a wide range of cancers.<br />

It uses high-energy x-rays to kill cancer cells or keep<br />

them from growing. Often, radiation therapy is used<br />

to cure early stage tumours. In some cases, where the<br />

cancer is diagnosed in the later stages and the tumor<br />

cells have already spread to other parts of the body<br />

such as bones, radiotherapy can still help to control<br />

troublesome symptoms such as pain.<br />

By Dr Anu Thiagarajan<br />

Consultant Radiation Oncologist<br />

NCCS<br />

However, one of the problems of standard radiation therapy has been<br />

collateral damage to surrounding healthy tissues. This occurs because<br />

the area selected for treatment usually includes the whole tumour<br />

plus a varying amount of normal tissue surrounding the tumour. This<br />

normal tissue is treated for two main reasons:<br />

(1) to take into account body movement from breathing and normal<br />

movement of the organs within the body, which can change the<br />

location of a tumour between treatments and<br />

(2) to reduce the likelihood of tumour recurrence from cancer cells<br />

that have spread to the normal tissue next to the tumour (called<br />

microscopic tumour spread).<br />

To minimise damage to neighboring healthy tissues, standard radiotherapy is generally<br />

given in many small doses over several weeks to allow the normal tissues to recover<br />

and regenerate. The total radiation dose administered is also kept comparatively low<br />

in order to protect sensitive normal tissues such as the spinal cord, which, if damaged,<br />

can have devastating consequences for patients, impacting on their daily functioning<br />

ability and quality of life. However, this may sometimes mean that tumours receive<br />

inadequate radiation doses and as a result, the chances of cure may be compromised.<br />

In recent years, the emergence of a new and exciting technology called stereotactic<br />

body radiation therapy (SBRT) has allowed radiation to be delivered with pinpoint<br />

accuracy. Because of the high-precision nature of this treatment, one of the key<br />

requirements to ensure success is mimimal body movement of patients during treatment.<br />

For this reason, during the radiotherapy planning session (also known as simulation), an<br />

immobilisation device is made to help patients remain still during radiation treatment.<br />

While many immobilisation devices are<br />

available, one of the more commonly<br />

used devices is called a BodyFIX bag. It<br />

consists of a bean bag that forms a cushion<br />

under the body, and a plastic sheet that<br />

covers the top of the body. The beanbag<br />

and top sheet are very loose at first, then<br />

tighten as a vacuum removes all the air,<br />

creating a stable and precise body mold.<br />

Once made, this mold is stored and used<br />

every time for treatment. When treatment<br />

is about to begin, a radiation therapist<br />

positions the patient on the treatment<br />

machine in the immobilisation device.<br />

Several images including CT scan images<br />

are taken to ensure that the patient is<br />

positioned accurately and adjustments<br />

are made if needed. The machine that<br />

delivers the radiation then moves around<br />

directing radiation to the body from<br />

several angles. With SBRT, the physician<br />

can even take into account movement of<br />

a tumour based on a patient’s breathing<br />

pattern. Such advancement in accuracy<br />

of radiation treatments means that much<br />

smaller margins of normal tissue are<br />

included in the area of treatment, thereby<br />

allowing much higher doses of radiation<br />

to be delivered, potentially improving the<br />

likelihood of killing the cancer cells of a<br />

tumour and increasing the chances of cure.<br />

Continued from page C3.<br />

At present, in NCCS, this treatment technique is primarily<br />

offered to patients with early stage lung cancer who<br />

are inoperable owing to poor medical health or those<br />

who refuse surgery. Normally, these patients are offered<br />

a 6-week course of conventional radiation treatment.<br />

However, outcomes have not been ideal with this approach,<br />

with tumour control achieved in only about 30-40% of<br />

patients and more than half of all patients dying from<br />

progressive disease within two years.<br />

Another benefit to the improved accuracy is that treatments can be completed in a short<br />

period of time. Traditional radiation therapy typically requires daily hospital visits, 5 days<br />

a week for five to six weeks. On the other hand, SBRT usually only requires one to five<br />

treatments over one to two weeks. This is of tremendous benefit particularly for patients who<br />

are working full-time, those with young families, those who have long distances to travel to<br />

get to hospital, as well as elderly patients who need assistance to get to and from hospital.<br />

This abbreviated course of radiation reduces the number of trips to the hospital and helps<br />

patients as well as care-givers resume their day-to-day lives as quickly as possible.<br />

As with any type of radiation, side effects may occur with SBRT. Specific<br />

side effects depend on the site being treated and can vary in severity<br />

from patient to patient. These side effects are usually minor, transient<br />

and resolve in the weeks following completion of radiation. Concerns<br />

about worse side effects because of the higher radiation doses used have<br />

fortunately not been seen with multiple trials consistently demonstrating<br />

that treatment-related toxicities were within the acceptable range.<br />

In NCCS, SBRT is delivered using one of two high-end state-of-the-art machines<br />

(Trilogy, or Tomotherapy). Both systems offer CT scanning capabilities, allowing<br />

radiation oncologists to confirm the precise location of tumours with CT scans prior to<br />

each treatment, make necessary adjustments, and administer radiation, all on the same<br />

machine. This gives the treating oncologist greater confidence that radiation is being<br />

delivered exactly as planned. However, the implementation of such complex treatment<br />

does come at a cost. It relies on modern, expensive equipment. It is labour-intensive,<br />

requiring specialised training and coordinated effort between radiation oncologists,<br />

medical physicists, and radiation therapists. Another factor that is key to the success<br />

and safe delivery of this technique is the development and implementation of rigorous<br />

quality assurance procedures. As such, stereotactic body radiation therapy is currently<br />

more expensive than conventional radiation treatment.<br />

At present, in NCCS, this treatment<br />

technique is primarily offered to<br />

patients with early stage lung cancer<br />

who are inoperable owing to poor<br />

medical health or those who refuse<br />

surgery. Normally, these patients<br />

are offered a 6-week course of<br />

conventional radiation treatment.<br />

However, outcomes have not been<br />

ideal with this approach, with tumour<br />

control achieved in only about 30-40%<br />

of patients and more than half of all<br />

patients dying from progressive disease<br />

within two years. With stereotactic<br />

radiation therapy on the other hand,<br />

the preliminary results have been far<br />

superior with long-term tumour control<br />

rates in excess of 70%. In spite of these<br />

promising results, SBRT is still in its<br />

infancy and longer follow-up of patients<br />

is needed to confirm these positive<br />

early results.<br />

Efforts are also currently underway to<br />

expand the usage of SBRT to include<br />

selected patients with spine and liver<br />

tumours. While SBRT is not suitable<br />

for every patient, its potential to be an<br />

effective and convenient alternative to<br />

conventional radiation therapy in the<br />

near future is immense.


PREETI’S LOVE<br />

TRANSCENDS BORDERS<br />

November / December 2010<br />

One concert every six months is what 17-year-old Preeti<br />

Varathan has been doing since 2007. But one particular<br />

concert holds a very special place in the heart of the carnatic<br />

violinist – the concert that took place in New York City this July.<br />

Preeti raised $40,000 for the <strong>National</strong> <strong>Cancer</strong> <strong>Centre</strong> <strong>Singapore</strong><br />

in support of cancer research. CHUA HWEE LENG reports.<br />

A<br />

young and bright lass,who glows<br />

with positive energy, Preeti is no<br />

stranger to cancer. The disease<br />

took her mother away from her life when<br />

she was only six years old. Her late<br />

mother, Madam Hema Devanathan was<br />

only 36 years old.<br />

Despite having witnessed her mother’s<br />

two-year-long struggle with lung cancer,<br />

Preeti did not allow the experience to<br />

wane her. Instead, she was determined<br />

to be stronger each day, refusing to<br />

allow the negative experience to occupy<br />

her thoughts.<br />

Withholding tears, she recounted how<br />

strong her mother was in her fight against<br />

cancer and how the tragic episode had<br />

then affected her.<br />

“Before she was diagnosed with cancer,<br />

I would read to her when I came home<br />

from school. After she was diagnosed<br />

with cancer, she started losing her hair<br />

and put on a lot of weight due to the<br />

treatment she received.<br />

“During later stages, she stayed in her<br />

room most of the time. But in spite of<br />

that, whenever I got home, she would<br />

still let me read to her. It was the kind of<br />

consistency; the little things that touched<br />

me. She wouldn’t allow her illness to<br />

change our routine. I think that was what I<br />

really respected in her,” said Preeti.<br />

Now, Preeti lives with this philosophy,<br />

“I am not the only person to face<br />

tragedy – almost everyone in the world<br />

does as well. But we must not let that<br />

deter us. We have to move on and<br />

pursue what we want for ourselves.”.<br />

Although Preeti was of a young age<br />

then, she understood that her mother<br />

was suffering from pain. However,<br />

Madam Devanathan never showed<br />

her weakness in front of the children.<br />

On her mother’s last gift to her, she<br />

said, “I think strength is what she has<br />

given me.”<br />

After her mother passed away and<br />

was cremated, Preeti and her sister<br />

accompanied their father to the Bay<br />

of Bengal in India to scatter her ashes.<br />

That was when she got exposed to the<br />

carnatic style of playing the violin. To<br />

fill the void in her life, she decided<br />

to go under the tutelage of famous<br />

Carnatic violinist Sri Vittal Ramamurthy.<br />

She learnt well and put her talent to<br />

good use – hosting concerts that raised<br />

funds for healthcare causes. This year<br />

marked her first solo concert outside<br />

India. It was also her first fund-raising<br />

concert for the cancer cause. She<br />

single-handedly booked the concert<br />

hall, printed invitations and posters,<br />

and invited two renowned artistes<br />

– Neyveli R. Narayanan and Samir<br />

Chatterjee – to be her accompanists.<br />

At the concert, which did not come at any<br />

ticket price, Preeti gave a presentation<br />

on cancer research to her audience. They<br />

were strangers to the <strong>National</strong> <strong>Cancer</strong><br />

<strong>Centre</strong> <strong>Singapore</strong> (NCCS). Preeti won their<br />

hearts with her touching presentation and<br />

her performance. The nearly 250-member<br />

audience donated close to $40,000 for<br />

cancer research.<br />

Preeti was not surprised by the warm response<br />

despite the almost 10,000 miles separating<br />

the beneficiary and the donors, as “this is a<br />

universal cause because almost everyone would<br />

know someone who is affected by cancer.”<br />

On why she chose NCCS as the beneficiary,<br />

Preeti said matter-of-factly, “I have been living<br />

here for nearly five years. As an individual<br />

in the community, I think the most important<br />

thing is to help the community around me.”<br />

Preeti, a permanent<br />

resident of <strong>Singapore</strong><br />

and a US Citizen, has<br />

set her sights on going to<br />

the US for further studies<br />

and may well hold<br />

another fund-raising<br />

concert in <strong>Singapore</strong><br />

which will again name<br />

NCCS as the beneficiary.

CHARITY: HER WAY OF LIFE<br />

SALUBRIS<br />

November / December 2010<br />

From Nurse to Administrator and now a<br />

Fund Raiser, that’s the span of job scope that<br />

Flora Yong has embraced since she joined<br />

the <strong>National</strong> <strong>Cancer</strong> <strong>Centre</strong> <strong>Singapore</strong>.<br />

The newly-appointed Manager at the NCCS Foundation,<br />

shares her thoughts with VERONICA LEE.<br />

If you’ve seen Flora Yong all dressed to<br />

the nines don’t be surprised. For her<br />

new role in the NCCS Foundation,<br />

that’s what she needs to do to meet up<br />

with corporate chiefs, business tycoons,<br />

donors and well-wishers. Perhaps some<br />

may still remember her as the woman<br />

with that rich and melodious voice<br />

making the public announcements<br />

twice a day at the <strong>Centre</strong> during the<br />

outbreak of the H1N1 flu some two years<br />

ago. Certainly with her demure and<br />

confident personality, good vocal chords<br />

and a sound knowledge about cancer,<br />

Flora is set to open more doors for<br />

the Foundation.<br />

With her new appointment as<br />

Manager of Community Partnership<br />

and Fundraising, she has a mammoth<br />

task ahead of her. Together with the<br />

Foundation’s Director Dr Tan Hiang<br />

Khoon, she will be building a new<br />

team for the fund-raising arm of NCCS.<br />

No longer is she worried about patient<br />

clinical issues. Instead she has to set<br />

her sights on how to help raise the<br />

millions that are required to support the<br />

many cutting-edge research projects<br />

undertaken by the clinicians and<br />

researchers at the NCCS laboratories.<br />

While she may not have worked in the<br />

laboratories, Flora is certainly familiar<br />

with medicines and their roles in saving<br />

lives. She was trained as a Staff Nurse<br />

before rising to Nurse Manager in<br />

the <strong>Singapore</strong> General Hospital. She<br />

joined NCCS in May, 1999 and started<br />

the <strong>Cancer</strong> Education and Information<br />

Service (CEIS), whose role was to<br />

provide public education on cancer and<br />

also to answer public inquiries on the<br />

<strong>Cancer</strong> Helpline.<br />

Under her watch, CEIS introduced<br />

many cancer awareness programmes for<br />

patients and the public and produced<br />

the inaugural issue of a newsletter that<br />

has an audience of 22,000 readers. The<br />

<strong>Cancer</strong> Helpline also took off successfully<br />

since it was launched in September 2000<br />

attracting more than 90 calls on the first<br />

day of its operations.<br />

The helpline now gets an average of 350<br />

contacts per month. Here she learnt to<br />

understand the demands and anxieties<br />

of the patients, and despite the heavy<br />

workload she had the satisfaction of being<br />

able to offer a listening ear and knowing<br />

that a few helpful words had calmed the<br />

nerves of the callers.<br />

Indeed, the love of sharing and offering<br />

her time for charitable causes was<br />

imbued in her since her growing up years<br />

in Batu Pahat, Johor. She would take part<br />

in fund-raising activities like Flag Day or<br />

sell cookies, cakes and candies baked by<br />

her mother, to support charitable causes.<br />

During the Christmas season, she would<br />

join a youth group of carolers to make<br />

their rounds to raise funds for the needy.<br />

As a Girl Guide in school, she visited<br />

old folks’ homes to help clean up their<br />

premises and bring cheer to them.

“It’s not only about giving money. It’s<br />

also about giving kindness in words<br />

and in deeds and that helps a lot<br />

especially to those who are faced<br />

with life-threatening illnesses. They<br />

need kind words and hands to hold<br />

on to for strength as they go through<br />

their arduous cancer journey.”<br />

Flora Yong<br />

Flora (second from left) with the former<br />

President Wee Kim Wee.<br />

Looking back at her childhood, she<br />

surmised that her love for charity just<br />

blossomed from there. “Helping did not<br />

mean much to me as a child. I just knew<br />

I had to be a good little girl and help<br />

whenever it was needed. Giving help<br />

holds a much deeper meaning to me<br />

now as an adult.<br />

“It’s not only about giving money. It’s also<br />

about giving kindness in words and in<br />

deeds and that helps a lot especially to<br />

those who are faced with life-threatening<br />

illnesses. They need kind words and<br />

hands to hold on to for strength as they go<br />

through their arduous cancer journey,” said<br />

Flora who is someone who walks the talk.<br />

She has offered her paintings for sale at a<br />

recent art exhibition in a bid to raise funds<br />

for patient support programmes. With her<br />

new role at NCCS Foundation, she feels she<br />

has come full circle and is all set for the<br />

greatest challenge – to raise funds for cancer<br />

research. Barely weeks into her job, she was<br />

thrown “into the deep end” and was roped<br />

into the working committee for the Run for<br />

Hope which was held on 21 Nov. The Run<br />

drew a record 7,000 participants and was<br />

organised jointly with the Four Seasons<br />

Hotel and the Regent Hotel.<br />

She tapped on her network and worked<br />

with Borders Bookstore for convenience<br />

of registering prospective participants<br />

at the bookstore in Orchard Road. In<br />

December, she arranged for teams of<br />

volunteers to do gift wrapping at the<br />

bookstore. In return, NCCS Foundation<br />

will sell the gift cards to raise money for<br />

cancer research.<br />

When asked why she felt charity was<br />

so important to her, she replied, “I have<br />

received many acts of kindness in my<br />

life. Although they were not monetary in<br />

value, each of them taught me valuable<br />

lessons on being generous and kind to<br />

others. So I want to keep this flame alive<br />

and pass it on to others. Everything comes<br />

full circle, I believe what I give now will<br />

be returned at a time when I least expect<br />

it and when I most need it.”<br />

Although she was at first apprehensive about<br />

her role in fund raising, Flora decided to<br />

take on the challenge as she believes she<br />

can help the Foundation to move on to its<br />

next phase given her background knowledge<br />

of NCCS. She sees it as an opportunity to<br />

push boundaries and see how far she can<br />

go. Speaking before audiences is something<br />

she does with confidence, having been<br />

the founding President of the SingHealth<br />

Toastmasters Club in 2004.<br />

But it is still early days as Flora confesses.<br />

The team is new and her immediate task<br />

is to help the team members learn the<br />

ropes. Believing that each of her team<br />

members have their own talents, she<br />

hopes they will contribute effectively and<br />

work cohesively towards the long term<br />

goals of raising funds and maintaining<br />

lasting relationships with donors.

NCCS CANCER CAUSES<br />

GET A STRONG BOOST<br />

FROM THE COMMUNITY<br />

As a finale to the year, NCCS saw another<br />

successful Run for Hope, an annual charity<br />

run in support of cancer research. Jointly<br />

organised by the Regent <strong>Singapore</strong>, Four<br />

Seasons Hotels & Resort, the event saw<br />

7,000 runners this year, a huge surge in the<br />

number of runners compared to last year’s<br />

6,000 signed up. One school of thought<br />

is that this increase may be indicative of<br />

the increasing number of people who are<br />

beginning to see the value in cancer research<br />

and in helping others who are less fortunate.<br />

A sum of $320,000 was raised from this run.<br />

The desire to help cancer patients and<br />

give them the hope to overcome their<br />

ordeal has won many kind hearts to<br />

support the cause promoted by NCCS.<br />

The NCCS cause is that for every dollar<br />

that is spent on research, the benefit to<br />

the community will be more far reaching<br />

than a dollar given to just one patient. A<br />

breakthrough in medical research will save<br />

more lives than monetary handouts to the<br />

patients. Without a cure, the outcomes for<br />

the patients will be a forgone conclusion.<br />

In the last quarter of 2010 NCCS, through<br />

various activities carried out by its<br />

Foundation, the fund-raising arm for cancer<br />

research as well as patient welfare, the<br />

support has been very encouraging.<br />

A good example is the effort undertaken by<br />

the Methodist Girls’ School teachers and<br />

students, together with their parents.<br />

The students from both the primary and<br />

secondary cohorts of the school, which is<br />

located at Blackmore Drive, presented<br />

another charity concert – for the second year.<br />

Entitled Sounds of Hope, the charity<br />

concerts were the brainchild of Mrs Shirleen<br />

Ong, Principal of the school, who wanted<br />

to support the cancer cause by expending<br />

her students’ artistic talents. Through sales<br />

of concert tickets, food items, MGS<br />

souvenirs and soliciting of donations<br />

from the parents, the school has raised<br />

close to $128,000 during the two years.<br />

This year also saw the students expending<br />

their efforts beyond fund raising. The<br />

students had embarked on several<br />

educational projects such as the creation<br />

of cancer blogs and the production of<br />

a storybook that was titled “Safaree”<br />

to illustrate the value of friendship and<br />

acceptance of one another.<br />

Prof Soo Khee Chee, Director of NCCS<br />

felt comforted by the response and<br />

generous donations from participants<br />

and well-meaning organisations. “We<br />

are very heartened by the overwhelming<br />

participation this year. It goes to show that<br />

many people understand the importance<br />

of cancer research…This will definitely<br />

encourage us at NCCS to put in even<br />

greater effort as we continue with our<br />

research work to find a cure for cancer.”<br />

The Run for Hope also continues to see its<br />

regular supporters from all communities in<br />

<strong>Singapore</strong> including expatriates, who apart<br />

from taking part in the run, also helped out<br />

for the event. More than 500 volunteers from<br />

Temasek Polytechnic, Hwa Chong Institution<br />

and Canadian International School came<br />

forward to help with race pack collection,<br />

marshaling and snacks distribution.<br />

NCCS researchers and doctors have not<br />

disappointed the donors. They have been<br />

making in-roads and more patients are<br />

getting better outcomes from their treatment.<br />
