title: [Retrospective analysis of 47 cases with hilar cholangiocarcinoma using T-staging system].
abstract: OBJECTIVE
  To evaluate the clinical value of T-staging system for hilar cholangiocarcinoma which was adopted in memorial Sloan-Kettering cancer center of New York.
  
  
  METHODS
  The image data of these 47 patients were analyzed retrospectively from December 1997 to December 2002 whose data were according with our demand, and they were staged into three-stage according to the criteria of the T-staging system. The difference of respectability, ratio of tumor-free resection margin and actuarial survival rate were analyzed for different T-staging. And the coincident ratio of three different kinds of imaging methods was also analyzed.
  
  
  RESULTS
  Twenty patients had T(1) tumors, twenty three had T(2) tumors and four had T(3) tumors. The resectability of the three stage was 60%, 39% and 0% respectively, and the difference was significant (P = 0.013). The likelihood of achieving tumor-free margin decreased progressively with increasing T stage (P = 0.018). The cumulative 1-year survival rates of T(1), T(2) and T(3) patients were 60%, 39% and 0% respectively, and the cumulative 3-year survival rate was 35%, 9% and 0% respectively, the survival of different stage patients differed markedly (P = 0.0103). The coincident ratio of combined using MRCP and color Doppler-ultrasonography was higher than that of combined using MRCP and B-ultrasonography or combined using CT/SCT and color Doppler-ultrasonography (P = 0.007).
  
  
  CONCLUSIONS
  The T-staging system has a better value for preoperative assessment, and can be used to judge resectability and survival of hilar cholangiocarcinoma. It will be helpful to use MRCP and color Doppler-Ultrasonography combined to verdict the coverage of the tumor and the T-staging preoperatively.
