This document is the first update of the American College of Gastroenterology (ACG) colorectal cancer (CRC) screening recommendations since 2000. The CRC screening tests are now grouped into cancer prevention tests and cancer detection tests. Colonoscopy every 10 years, beginning at age 50, remains the preferred CRC screening strategy. It is recognized that colonoscopy is not available in every clinical setting because of economic limitations. It is also realized that not all eligible persons are willing to undergo colonoscopy for screening purposes. In these cases, patients should be offered an alternative CRC prevention test (flexible sigmoidoscopy every 5-10 years, or a computed tomography (CT) colonography every 5 years) or a cancer detection test (fecal immunochemical test for blood, FIT).
本文档是美国胃肠病学会（ACG）自2000年以来对结直肠癌（CRC）筛查建议的首次更新。CRC筛查测试现分为癌症预防测试和癌症检测测试。从50岁开始，每10年进行一次结肠镜检查仍然是首选的CRC筛查策略。由于经济限制，人们认识到并非在每个临床环境中都能进行结肠镜检查。也意识到并非所有符合条件的人都愿意为了筛查目的而接受结肠镜检查。在这些情况下，应向患者提供替代的CRC预防测试（每5 - 10年进行一次乙状结肠镜检查，或每5年进行一次计算机断层扫描（CT）结肠成像）或癌症检测测试（粪便免疫化学潜血检测，FIT）。
