At least 10% of pancreatic cancer cases are due to an inherited predisposit
ion. The precursor lesion to pancreatic cancer is dysplasia. Endoscopic sur
veillance of high-risk families who inherit pancreatic cancer can be perfor
med at centers experienced in early diagnosis of pancreatic neoplasia. Endo
scopic ultrasound and ERCP can help identify patients who have pancreatic c
ancer and determine if a pancreatectomy is warranted. Careful selection of
patients, the timing of the operation, and an experienced team of gastroent
erologists, pancreatic surgeons, pathologists and diabetologists are the ke
y to a good surveillance program.
