Long-term Risk of Malignancy in Branch-Duct Intraductal Papillary Mucinous Neoplasms

Long-term outcomes of patients with branch-duct intraductal papillary mucinous neoplasms (IPMNs), particularly those after 5 years of surveillance, have not been fully evaluated in large studies. We analyzed incidences of IPMN-derived carcinoma and concomitant ductal adenocarcinoma (pancreatic ductal adenocarcinoma [PDAC]) over 20 years in a large population of patients.We identified 1404 consecutive patients (52% women; mean age, 67.5 years)...
