Screening for Pancreatic Cancer in High-risk Populations. Pancreatic adenocarcinoma is a leading cause of cancer death. Few patients are candidates for curative resection due to the late stage at diagnosis. While most pancreatic adenocarcinomas are sporadic, approximately 10% have an underlying hereditary basis. Known genetic syndromes account for only 20% of the familial clustering of pancreatic cancer cases. The majority are due to non-syndromic aggregation of pancreatic cancer cases or familial pancreatic cancer. Screening aims to identify high-risk lesions amenable to surgical resection. However, the optimal interval for screening and the management of pancreatic cancer precursor lesions detected on imaging are controversial.
