Colonoscopy is expected to reduce colorectal cancer (CRC) incidence in Lynch syndrome (LS) by detecting and removing adenomas. The existence of gene-specific differences in adenoma detection has been proposed yet remains insufficiently explored.
Conclusions
Carriers of MLH1/MSH2 pathogenic variants are at a higher risk of developing AAs compared with those with MSH6/PMS2 mutations, with MSH6 carriers exhibiting an intermediate risk profile. Advanced adenomas(AA) are an independent risk factor for post-colonoscopy CRC . LS patients with AAs should be identified as high risk and undergo enhanced colonoscopy surveillance.
