Pancreatectomy predicts improved survival for pancreatic adenocarcinoma: results of an instrumental variable analysis.

Background and Objective Pancreatic resection is the standard therapy for patients with stage I/II pancreatic ductal adenocarcinoma (PDA), yet many studies demonstrate low rates of resection. The objective of this study is to evaluate whether increasing resection rates would result in an increase in average survival in patients with stage I/II PDA.
