MMR Mutation

The impact of small bowel (SB) capsule endoscopy (CE) on the screening (followed by diagnosis and treatment) of (pre)neoplastic lesions of the small bowel in Lynch syndrome (LS) patients is unknown. The iCARE4Lynch study is a retrospective cohort of patients carrying a pathogenic variant of the DNA mismatch repair gene (MMR) (MLH1, MSH2, MSH6, PMS2, EPCAM) who had had at least one SBCE for screening of small bowel (pre)neoplastic lesions between January 1st 2000 and December 31 2024.

This study aims to define the natural history of men at high genetic risk for prostate cancer on the basis of specific germline genetic mutations, family history, or Black/African ancestry and evaluate the utility of prostate MRI as a screening tool. The hypothesis is that this targeted population of men are at elevated risk of developing prostate cancer compared to the general population, and enhanced screening with MRI will enable early detection and diagnosis of potentially aggressive prostate cancer, characterization of the penetrance of specific mutations, and potentially identify new genetic risk mutations.
