Abstract
Purpose:Serous uterine cancer is not a feature of any known hereditary cancer syndrome. This study evaluated familial risk of cancers for serous uterine carcinoma patients, focusing on Lynch syndrome malignancies.
CONCLUSIONS: We identified an excess of endometrial, ovarian, and pancreatic cancers in relatives of serous cancer patients in a single institution study. Follow-up studies suggest only pancreatic cancers are over-represented in relatives. DNA mismatch repair defects in familial clustering of pancreatic and other Lynch-associated malignancies are unlikely. The excess of pancreatic cancers in relatives may reflect an as yet unidentified hereditary syndrome that includes uterine serous cancers.
