Intraductal papillary mucinous neoplasm (IPMN) is a cyst-like cancer of the pancreas that is increasingly being identified in medical practice, including during the screening of individuals at high risk of pancreatic cancer. It has been established that 10 to 20% of pancreatic cancers are familial. In comparison, there has been little research into the importance of genetic risk in IPMN incidence. The investigators will perform a retrospective chart review of patients with IPMN who were evaluated for surgical intervention at our tertiary referral center. The investigators are interested in determining the proportion of IPMN patients with a family history of pancreatic and other cancers. In addition, the investigators will assess if familial cancer risk is associated with increased risk for malignant IPMN and recurrence, relative to those patients without an inherited predisposition.
