Abstract

Background: The introduction of FOLFIRINOX regimen greatly changed the treatment for advanced pancreatic cancers. However, detailed studies on the clinical effects and factors affecting the prognosis are insufficient. We performed this study to evaluate the effects of FOLFIRINOX and the surgical resection in advanced pancreatic cancer. Methods: Three hundred and thirty-seven patients with advanced pancreatic cancer who initially received FOLFIRINOX, from January 2011 to December 2017, were retrospectively reviewed. Patients were evaluated according to the National Comprehensive Cancer Network guideline, responses after four to six cycles of FOLFIRINOX were re-evaluated according to the response evaluation criteria in solid tumors, and further treatment was decided in the multidisciplinary meeting. Results: Sixty-seven (19.9%) patients had borderline resectable pancreatic cancer, 135 (40.1%) locally advanced pancreatic cancer, and 135 (40.1%) metastatic pancreatic cancer. The median survival period was significantly longer in the surgical group than in the nonsurgical group in each clinical stage, even in metastatic pancreatic cancer (32 vs. 14, P = 0.012). In multivariate analysis, metastatic status at diagnosis, progressive disease after FOLFIRINOX, surgical resection, and declined CA19-9 after FOLFIRINOX were significant prognostic factors. Conclusions: Surgical treatment greatly affects survival outcomes in advanced pancreatic cancer treated with FOLFIRINOX. Further studies on the optimal indication of operation and the protocol are needed.
