We are unaware of evidence that would support the assertion that colorectal cancer (CRC) rates in a low-risk population should converge with CRC rates in the general population. We believe that a high-quality negative colonoscopy result identifies individuals who are at low risk of developing CRC. Our findings suggest that this group continues to have a decreased risk of developing CRC even beyond 10 years following performance of their initial negative colonoscopy result and are supported by another recent study.3
Church further suggests that the incidence of CRC in our cohort may be artificially depressed by our excluding individuals with inflammatory bowel disease (IBD) or with a prior history of large bowel resection from the negative-colonoscopy cohort.
