Menée en Norvège à partir des données du registre des cancers, du registre des actes décès et portant sur 40 826 patients, cette étude analyse la mortalité par cancer colorectal chez des patients ayant subi la résection d'un adénome (durée médiane de suivi : 7,7 ans)
In March 2014, newspaper headlines trumpeted the stunning reduction in mortality from colorectal cancer of 30% from 2000 to 2010 in the United States.1 There were also significant reductions in colorectal-cancer incidence. Some of this reduction is due to colonoscopic detection and removal of adenomas.2,3 Patients in whom adenomas develop remain at risk (owing to genetics or lifestyle) for the discovery of adenomas on subsequent examinations, leading to the logical rationale for surveillance colonoscopy in adenoma-bearing patients.4
