New guidelines published in the February issue of Gastroenterology by the U.S. Multisociety Task Force on Colorectal Cancer differ from previous guidelines in several important ways.
They still emphasize the importance of starting screening at age 50 years but reduce the frequency of follow-up for those with positive findings. The task force generally favors colonoscopy over barium enemas, and it updates screening recommendations for familial adenomatous polyposis (FAP) and hereditary nonpolyposis colorectal cancer (HNPCC). Although the future of screening looks bright, with Medicare and other insurance carriers covering the costs, and new procedures and tests under development, the task force reminds doctors that they must recommend the tests.
