Progress report: familial pancreatic cancer.

A hereditary predisposition to pancreatic ductal adenocarcinoma (PDAC) is reported in approximately 5% of patients. Familial pancreatic cancer (FPC) accounts for the vast majority of hereditary PDAC cases. FPC defines families with two or more affected first-degree relatives with PDAC that do not fulfil the criteria of any other inherited tumor syndrome or families with PDAC in three or more relatives of any degree. The current progress report focuses on the knowledge of FPC with regard to molecular pathogenesis, clinical and molecular diagnosis, surveillance and novel treatment options reported in the last 5 years.
