Conclusions<br />
offered screen<strong>in</strong>g for adenomatous polyps and<br />
cancer <strong>with</strong> one of the follow options: Fecal<br />
occult blood test<strong>in</strong>g annually <strong>with</strong> a sensitive<br />
guaiac or immunochemical test, FS every 5 years,<br />
preferably both comb<strong>in</strong>ed, colonoscopy every 10<br />
years, or DCBE <strong>with</strong> FS every 5 - 10 years.<br />
People <strong>with</strong> 1 or 2 first-degree relatives <strong>with</strong><br />
colorectal cancer or an adenomatous polyp<br />
under age 60 should be offered screen<strong>in</strong>g<br />
beg<strong>in</strong>n<strong>in</strong>g at age 40 <strong>with</strong> one of the above<br />
options. A family history consistent <strong>with</strong> FAP or<br />
HNPCC requires genetic counsell<strong>in</strong>g, possibly<br />
genetic test<strong>in</strong>g and more <strong>in</strong>tense surveillance at a<br />
younger age.<br />
There exists Level I evidence that screen<strong>in</strong>g<br />
reduces the mortality from CRC (A<br />
recommendation) and the cost effectiveness of a<br />
screen<strong>in</strong>g program compares favourably <strong>with</strong><br />
<strong>in</strong>itiatives for breast and cervical cancer. Fecal<br />
occult blood test<strong>in</strong>g (FOBT), endoscopy<br />
(<strong>in</strong>clud<strong>in</strong>g sigmoidoscopy and colonoscopy),<br />
barium enema and virtual colonoscopy were<br />
considered. Although most cl<strong>in</strong>ical efficacy data<br />
are available for FOBT and sigmoidoscopy, there<br />
are limitations to programs based on these<br />
strategies. FOBT has a high false positive rate and<br />
a low detection yield, and even a comb<strong>in</strong>ation of<br />
these strategies will miss 24% of cancers.<br />
Colonoscopy is the best strategy to both detect<br />
and remove polyps and to diagnose colorectal<br />
cancer, <strong>with</strong> double contrast barium enema also<br />
be<strong>in</strong>g a sensitive detection method.<br />
The Task Force recommended the establishment,<br />
<strong>in</strong> Quebec, of a screen<strong>in</strong>g program <strong>with</strong> 5- to 10yearly<br />
double contrast barium enema or 10yearly<br />
colonoscopy for <strong>in</strong>dividuals aged 50 years<br />
or older at low risk. The program should <strong>in</strong>clude<br />
outcome monitor<strong>in</strong>g, public and professional<br />
education to <strong>in</strong>crease awareness and promote<br />
compliance, and central coord<strong>in</strong>ation <strong>with</strong> other<br />
prov<strong>in</strong>cial programs. The program should be<br />
evaluated; specific bill<strong>in</strong>g codes for screen<strong>in</strong>g for<br />
colorectal cancer would help facilitate this.<br />
Formal feasibility, effectiveness and costeffectiveness<br />
studies <strong>in</strong> Quebec are now<br />
warranted.<br />
