• Note (General): type:Thesis; Background: There is increasing need to evaluate the surgical indication of pancreatic cancer in very elderly patients. However, the available clinical data are limited, and the optimal treatment is still controversial. The aim of this study was to evaluate the benefit of pancreatic resection in pancreatic cancer patients over the age of 80. Methods: Between 2005 and 2012, 26 octogenarian patients who received pancreatic resection and 20 who received chemotherapy for pancreatic cancer were retrospectively reviewed. Clinicopathological factors, chemotherapy administration status, and survival were compared. Univariate and multivariate analysis of prognostic factors for survival was performed. Results: Postoperative major complication rate was 8%, with no mortality. The one-year survival rate and median survival time of the surgery and chemotherapy groups were 50% and 45%, and 12.4 months and 11.7 months, respectively (P = 0.263). Of the 26 resected cases, 6 completed the planned adjuvant chemotherapy treatment course. The median survival time of those 6 completed cases was significantly longer than that of the 20 not completed cases (23.4 versus 10.0 months, P = 0.034). Furthermore, a multivariate analysis of the 26 resected cases showed that distant metastasis (HR 3.206, 95%CI 1.005-10.22, P = 0.049) and completion of the planned adjuvant therapy (HR 4.078, 95%CI 1.162-14.30, P = 0.028) were independent prognostic factors of surgical resection. Conclusions: Surgical resection was safe, but not superior to chemotherapy for pancreatic cancer in octogenarians. In the very elderly, only selected patients may benefit from pancreatic resection.; 博士（医学）・乙第1513号・令和3年12月21日; Copyright © 2015 IAP and EPC. Published by Elsevier, a division of RELX India, Pvt. Ltd.
