摘要: Abstract Background & Aims: Identification of the hereditary nonpolyposis colorectal cancer (HNPCC) syndrome enables prevention (CRC) by means colonoscopy and polypectomies. We evaluated efficacy screening in a controlled trial over 15 years. Methods: Incidence CRC survival were compared 2 cohorts at-risk members 22 families with HNPCC. Colonic at 3-year intervals was arranged for 133 subjects; 119 control subjects had no screening. Genetic testing offered to whose causative mutation known. Results: developed 8 screened (6%) 19 (16 %; P = 0.014). The rate reduced 62%. In mutation-positive alone, rates 18% 41% controls ( 0.02). decrease resulted from removal adenomas 13 individuals (30%) 6 unknown status (40%). All CRCs study group local, causing deaths, 9 deaths caused controls. overall death 10 vs. 26 groups 0.003), 4 12 0.05). Conclusions: Colonoscopic more than halves risk CRC, prevents decreases mortality about 65% HNPCC families. GASTROENTEROLOGY 2000;118:829-834
