BACKGROUND: In 2007, Ontario launched a colon cancer screening program for average-risk individuals based on biennial fecal occult blood tests (FOBTs) on three fecal samples, followed by colonoscopy for individuals who tested positive.OBJECTIVE: To determine whether >1 positive screening FOBT was predictive of finding advanced neoplasia at colonoscopy.METHODS: A retrospective chart review of outpatient colonoscopic procedures performed at Hotel Dieu Hospital (Kingston, Ontario) in the first two years of the colon cancer screening program was conducted, focusing on endoscopic and pathological findings.RESULTS: Of 5556 individuals undergoing colonoscopy, 346 were referred for positive FOBT. Overall, 41 (11.8%) patients with a positive FOBT had colon cancer. In 16 (4.6%) cases, the number of positive FOBTs was not reported. For the 330 individuals in whom the number of positive tests was specified, 198, 71 and 61 cases had one, two and three positive results, respectively. Cancer was found at colonoscopy in 11 (5.6%), 11 (15.5%) and 18 (29.5%) of individuals with one, two and three positive FOBT results, respectively (OR 3.0 [95% CI 1.2 to 7.3] and 6.5 [95% CI 2.8 to 15.0] for two or three positive FOBTs compared with one; P=0.015 and P<0.001, respectively). High-risk adenomas (>1 cm in diameter, villous component and/or high-grade dysplasia) were found in 41 (20.8%), 29 (42.0%) and 25 (41.0%) individuals with one, two and three positive FOBTs, respectively (OR 2.8 [95% CI 1.5 to 5.0] and 2.4 [95% CI 1.3 to 4.5] for two or three positive FOBTs compared with one; P=0.001 and P=0.006, respectively).CONCLUSIONS: The diagnostic yield of colonoscopy varied directly with the number of positive FOBTs. This information may be useful in assigning scheduling priority for patients with positive FOBTs.

INTRODUCTION: Compliance with colorectal cancer (CRC) screening in Canada is low. The aim of the present survey was to determine whether Canadian physicians older than 50 years were pursuing colon cancer screening. Specifically, physicians were asked to identify their modality of choice and identify their barriers to screening.METHODS: Surveys were mailed to members, older than 50 years, of the Canadian Association of Gastroenterology, the Society of Obstetricians and Gynaecologists of Canada, the Canadian Society of Internal Medicine, the Canadian Psychiatric Association and the Canadian Association of Radiologists.RESULTS: Of 2807 surveys, 46% were returned. Screening for CRC was reported by 53% of respondents. The Canadian Association of Radiologists members (61%) and the Canadian Association of Gastroenterology members (61%) were more likely to be screened than other specialties (P<0.01 and P<0.05, respectively). Members of the Society of Obstetricians and Gynaecologists of Canada (44%) were least likely to be screened (P<0.001). Men (P<0.001) and Ontario physicians (P<0.01) were more likely to be screened than women and Canadian physicians from other provinces, respectively. Colonoscopy (56%) was the most common screening modality used, followed by fecal occult blood testing (27%). Respondents who had not been screened cited a lack of personal time (47%) and insufficient data to warrant screening (14%).DISCUSSION: More than one-half of all respondents were screened for CRC. Colonoscopy is the most common screening modality used. Lack of time is the most common reason cited for not participating in CRC screening.

The Canadian Association of Gastroenterology and the Canadian Digestive Health Foundation published guidelines on colon cancer screening in 2004. Subsequent to the publication of these guidelines, many advances have occurred, thereby necessitating a review of the existing guidelines in the context of new technologies and clinical knowledge. The assembled guideline panel recognized three recent American sets of guidelines and identified seven issues that required comment from a Canadian perspective. These issues included, among others, the role of program-based screening, flexible sigmoidoscopy, computed tomography colonography, barium enema and quality improvement. The panel also provided context for the selection of the fecal immunochemical test as the fecal occult blood test of choice, and the relative role of colonoscopy as a primary screening tool. Recommendations were also provided for an upper age limit for colon cancer screening, whether upper endoscopy should be performed following a negative colonoscopy for a positive fecal occult blood test and when colon cancer screening should resume following negative colonoscopy.
