The Clinical Value Of T-staging System In The Preoperative Assessment Of Hilar Cholangiocarcinoma

Objective:To investigate the clinical value of T-staging system in the preoperative assessment of hilar cholangiocarcinoma.Methods:From May2009to November2011,42patients who had cholangiocarcinoma diagnosed by operative tissue-biopsy were placed into one of three stages based on the new T-staging system, and it was evaluated the resectability and survival correlated with T-staging.Results:Vival of different stage patients differed markedly (P<0.001). Median survival in the The likelihood of resection and achieving tumor-free margin decreased progressively with increasing T stage (P<0.05). The cumulative1-year survival rates of T1, T2and T3patients were71.8%,50.8% and12.9% respectively, and the cumulative3-year survival rate was34.4%,18.2% and0% respectively; the surhepatic resection group was greater than in the group that did not undergo hepatic resection (23mo vs19mo; P<0.05).Conclusions:The proposed staging system for hilar cholangiocarcinoma can accurately predict resectability, the likelihood of metastatic disease, and survival. A concomitant partial hepatectomy would help to attain curative resection and the possibility of long-term survival.
