The recent analysis made available in the 2010 ColonCancerCheck Program Report, provides us with a picture on our performance in colorectal cancer screening.
It shows that FOBT participation rates among the targeted population increased steadily between 2003 and 2008, with a slight decrease in 2009-2010 for all age groups in most LHINs. In 2009-2010, 27% of eligible Ontarians completed an FOBT test in the prior 2 years (33% for Champlain LHIN).
The % of eligible Ontarians who were up to date with colorectal tests including FOBT in the last 2 years, or flexible sigmoidoscopy in the last 5 years, or colonoscopy in the previous 10 years, increased steadily and reached 53% in 2010 (55% for Champlain LHIN).
Overall, 5% of men and 3.4 % of women aged 50-74 had an abnormal FOBT test in 2010. The % of those who had an abnormal FOBT who went on to colonoscopy increased from 63% in 2008 to 71% in 2010 (70% for Champlain LHIN). Those with an abnormal FOBT who went on to endoscopy, 5.4% were found to have colorectal cancer.
In 2010, 1.5 cancers were detected per 1000 people aged 50-74 who were screened with FOBT. In 2010, 4.3 cancers were detected per 1000 people aged 20-74 who had a positive family history and were screened with colonoscopy.
The 2010 program report shows a general improvement for the ColonCancerCheck Program, but still almost 50% of Ontarians remain unscreened. CCO will continue to focus on increasing screening participation rates by sending screening invitations to all eligible Ontarians. It will also focus on improving follow up colonoscopy rates after an abnormal FOBT. Mortality benefits can only be achieved by improving our performance in colorectal cancer screening.
