摘要

Colorectal cancer is one of the most common cancers in Germany among both sexes and is the leading cause of cancer-related mortality. In 2002, colonoscopy screening was introduced without sufficient evidence of its benefits. In many other European countries, sigmoidoscopy screening is preferred. In 2022, the first randomized study on colonoscopy screening was published: the benefits of colonoscopy screening are very low: participation does not affect overall mortality. New to the German S3 guideline are the recommendations for equal use of sigmoidoscopy, sequential screening using the immunochemical fecal occult blood test (iFOBT), and colonoscopy only in the case of a positive test—and as direct colonoscopy. Corresponding decision-making aids for consultation in general practice have been developed.
