BACKGROUND Screening for colorectal cancer with sigmoidoscopy benefits from the fact that distal findings predict the risk of advanced proximal neoplasms (APNs). This study was aimed at comparing the existing strategies of postsigmoidoscopy referral to colonoscopy in terms of accuracy and resources needed. METHODS Asymptomatic individuals aged 50-69 years(More)

METHODS We identified asymptomatic men and women, 50-69 years old, through community health registries and randomly(More)

METHODS In this randomized, controlled trial involving asymptomatic adults 50 to 69 years of age, we compared one-time colonoscopy in 26,703 subjects with FIT every 2 years in 26,599 subjects.
