Prognostic Factors after Pancreatoduodenectomy for Distal Bile Duct Cancer

Prognostic factors influencing long-term survival after radical resection for distal bile duct cancer have not been well established because of the rarity of this malignancy. The goal of this study was to identify main prognostic factors in patients undergoing pancreatoduodenectomy for distal bile duct carcinoma. A retrospective study consisting of 122 patients with distal bile duct cancer who underwent pancreatoduodenectomy in three major university hospitals was performed to identify the main prognostic factors. Major surgical complications occurred in 40 patients (32.8%), of whom eight died (6.6%) in the hospital. Overall actuarial survival (excluding hospital deaths) at 1-, 3-, and 5-year follow-up was 82.9, 49.4, and 32.7 per cent, respectively, with a median survival of 36 months. Univariate analysis showed that papillary tumor (P = 0.045), negative surgical margin (R0 resection, P = 0.005), earlier pT (P = 0.005), pTNM stage (P < 0.001), and absence of lymph node involvement (P < 0.0001) were significant predictors of survival. On multivariate analysis, only lymph node metastasis was shown to be an independent prognostic factor of survival (P = 0.036). Lymph node involvement was the most important survival predictor after a Whipple resection in patients with distal cholangiocarcinoma.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000296316900009&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701SurgerySCI(E)11111445-14487
