Approach to colon polyps in the elderly

Colorectal cancer is a common but potentially preventable disease. Nearly all colorectal cancers are thought to arise from adenomatous polyps. The conclusions from the National Polyp Study strongly support the concept that the removal of polyps may prevent the future development of colorectal cancer. With the growing acceptance of screening for colorectal cancer, many elderly patients with adenomatous polyps will be discovered. Because increasing age is a powerful determinant of a higher prevalence of colonic neoplasia in asymptomatic individuals, physicians will need to be prepared to make informed decisions regarding the treatment of elderly patients with colonic polyps. The literature is reviewed and guidelines are formed regarding the optimal surveillance interval for patients with colonic polyps. The age at which surveillance and screening for colorectal neoplasia should stop is also reviewed. Conclusions are based on the currently available data.
