Research output: Contribution to journalArticlepeer-review


Colorectal cancer is one of the most frequent neoplasms in Western countries with an estimated 400,000 deaths per year worldwide. Several randomized studies have demonstrated that screening programs with FOBT (Fecal Occult Blood Test) reduce mortality from 18 to 33%, whereas case-control and cohort studies with endoscopy have shown a mortality reduction ranging from 60 to 76%. The target population for secondary prevention is men and women aged more than 50 years and younger subjects in case first-degree relatives are affected or the family pedigree raises the suspicion of a genetic syndrome. This report summarizes the results of different screening strategies for average risk patients (FOBT, anamnestic risk questionnaire, sigmoidoscopy, colonoscopy and virtual colonoscopy) and the surveillance protocols applicable to high-risk patients, particularly for hereditary syndromes such as HNPCC and FAP.
