Current guidelines recommend that flexible sigmoidoscopy screening for colorectal cancer be repeated 5 years after a negative examination, but the optimal screening interval is uncertain. In this analysis of data from the intervention arm of the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial, a trial evaluating the effectiveness of cancer screening tests on site-specific cancer mortality, Schoen and colleagues Article found that the incidence of adenoma or cancer in the distal colon 3 years after a negative examination was 3.1% and the incidence of advanced adenoma or cancer was 0.8%. In an editorial, Fletcher Article discusses how frequently screening sigmoidoscopy should be repeated, whether sigmoidoscopy is effective enough relative to other available screening tests, and how to make sigmoidoscopy available to all adults who want to be screened.
