Abstract
With cholangiocarcinoma, the only hope of a cure is resection. This study was undertaken to determine the impact of margin status, stage, tumor location, and adjuvant therapy on survival after resection of extrahepatic cholangiocarcinoma. From 1985-2006, 91 patients underwent resections of cholangiocarcinomas. Margin status was codified as micro-/macroscopically negative, microscopically positive/ macroscopically negative, or micro-/macroscopically positive. Stage was determined using the AJCC classification (6th edition). Tumor location was classified as proximal, mid, or distal. Proximal tumors were resected by extrahepatic biliary resection with/without concomitant hepatic resection (n = 48), distal extrahepatic cholangiocarcinomas by pancreaticoduodenectomy (n = 35), and mid tumors by extrahepatic biliary resection alone (n = 8). Regression analysis and survival curve analysis were utilized. Data are presented as median, mean +/- standard deviation (SD). Overall survival after resection was 21 months, 38 +/- 46.0. Survival was not impacted by margin status (R0 20 months, 35 +/- 45.1 versus R1 32 months, 45 +/- 49.4). AJCC stage inversely correlated with survival (p = 0.004, Spearman regression analysis). Tumor location did ...Continue Reading
