Germline variants in CDH1 are associated with elevated risks of diffuse gastric cancer and lobular breast cancer. It is uncertain whether there is an increased risk of colorectal neoplasia.This was a retrospective analysis of colonoscopy outcomes in patients with germline CDH1 pathogenic/likely pathogenic variants.Eighty-five patients were included with a mean age of 46.9 years. Initial colonoscopy found adenomatous polyps in 30 patients (35.3%), including advanced adenomas in 9 (10.6%). No colorectal cancers were identified on index or subsequent colonoscopies (when available).CDH1 carriers have colorectal neoplasia identified at similar rates as in the general population. Despite potential difficulties after gastrectomy, colorectal cancer screening remains important in this population.
