Objectives: The objective of this study was to investigate the pattern and the oncologic impact of local recurrence after surgical resection of pancreatic cancer. Methods: From July 1992 to December 2016, 388 patients who underwent curative-intent surgery for pancreatic ductal adenocarcinoma were retrospectively reviewed. Results: At a median follow-up of 29.0 months, 286 (73.7%) of the 367 patients experienced recurrence, and the 5-year overall survival rate was 31.3%. The first recurrence pattern was local in 83 patients (22.0%), systemic in 152 patients (40.2%), and locosystemic in 51 patients (13.5%). There was no difference in overall survival between the patients who had either local or systemic recurrence (P > 0.05). Remnant pancreas, common hepatic artery, celiac trunk, and para-aortic area were the common local recurrence sites in both head and body/tail cancer. However, the superior mesenteric artery (P = 0.050) and portal vein (P = 0.001) were more frequent local recurrence sites for a head tumor, and the surgical bed was a common recurrence site for body/tail tumor (P < 0.001). Conclusions: Our study shows the importance of local recurrence on overall survival and that preferred sites of local recurrence according to tumor location are predictable.
