What is the rate of development of colorectal cancer in older patients with colon polyps?
In a population of older patients (65 years and older) with colon polyps identified by colonoscopy, few — 0.2% — will develop colon cancer. It may be time to re-evaluate the current recommendations for 5-year surveillance in older patients with previously identified polyps, especially for patients with a calculated shorter life expectancy. (LOE = 1b)
Overuse alert: This POEM aligns with the Canadian Association of General Surgeons’ Choosing Wisely Canada recommendation: Avoid colorectal cancer screening tests in asymptomatic patients with a life expectancy of less than 10 years and with no personal or family history of colorectal neoplasia.
