We performed a simulation study to examine and compare the optimal ages to have once-only screening colonoscopy and repeated colonoscopies.A Markov model was set up using data from the German national screening colonoscopy registry to simulate the natural history of the adenoma-carcinoma process. CRC deaths and years of potential life lost (YPLL) for a hypothetical unscreened 50-year-old German population were estimated for a single screening colonoscopy or 2 or 3 screening colonoscopies with 10-year intervals at various ages.One single screening colonoscopy performed between 50 and 65 years of age was expected to reduce CRC death by 49 LB - PUB:(DE-HGF)16 C6 - pmid:30639539 DO - DOI:10.1016/j.gie.2018.12.021 UR - https://inrepo02.dkfz.de/record/143557 ER -
