Does acute pancreatitis herald pancreatic ductal adenocarcinoma? A multicenter electronic health research network study.

AP is infrequently associated with PDAC and can precede a diagnosis of PDAC in a minority of patients without another known etiology of pancreatitis. Patients with a recent AP are more likely to undergo surgical resection of PDAC and a trend toward diagnosis at an earlier stage compared to patients with PDAC and without AP. The impact of AP-related PDAC on survival is unknown.
