243Background: The number of incidentally discovered asymptomatic pancreatic ductal adenocarcinoma (APDAC) has been increasing along with recent wide spread use of imaging studies in general practice. However, the clinical implication in early detection of asymptomatic pancreatic cancer remains yet to be determined. In this study, we reviewed our experience of patients with PDAC in high volume cancer center and compared the characteristics and long-term outcomes between those with APDAC and symptomatic PDAC (SPDAC). Methods: This retrospective study included 569 consecutive patients with PDAC initially treated in our institution from January 2007 to December 2012. Median follow-up period was 29 months for the survivors. Two hundred and fifty patients underwent surgical resection and 319 patients were deemed unresectable. The patient’s demographics, tumor locations, pathologic stages, and treatment type received, and the overall survival (OS) were compared between the patients with APDAC and those with SPD...
