Indication for postoperative adjuvant therapy in biliary carcinoma based on analysis of recurrence and survival after surgical resection
Abstract
Postoperative adjuvant therapy is mandatory for biliary carcinoma because of its unfavorable prognosis. The aim of this study was to evaluate the indication for postoperative adjuvant therapy in biliary carcinoma. The charts of 139 consecutive patients with biliary carcinoma (37 ampullary carcinomas, 36 distal carcinomas, 38 carcinomas of the gallbladder, and 28 hilar cholangiocarcinomas) who underwent surgical resection were retrospectively reviewed. Recurrence rates and survival rates after surgery were analyzed. Of the 139 carcinomas, the recurrence rates of International Union Against Cancer (UICC) stages IA, IB, IIA, IIB, and III cancers were 9%, 20%, 60%, 83%, and 100%, respectively. The recurrence rates of UICC stages II and III cancers were significantly higher than that of UICC stage I cancer (82% vs 13%, P < 0.001). The 5-year survival rates for patients with UICC stages IA, IB, IIA, IIB, and III cancers were 85%, 75%, 36%, 20%, and 0%, respectively. The 5-year survival rates for UICC stages II and III cancers were significantly lower than that for UICC stage I cancer (21% vs 82%, P < 0.001). Postoperative adjuvant therapy should be given to patients with UICC stages II and III biliary carcinomas because of their high rate of recurrence and the poor prognosis.
