INTRODUCTION: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.METHODS:This was a retrospective analysis of colonoscopy outcomes in patients with germline CDH1 pathogenic/likely pathogenic variants.RESULTS: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).DISCUSSION: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.
