ABSTRACT
Objective@#To compare the Bismuth-Corlette typing, modified T-staging and Mayo staging system in predicting the radical resection rates and prognosis of patients with hilar cholangiocarcinoma (HCC).@*Methods@#The clinical data of 138 patients with hilar cholangiocarcinoma treated in the First Bethune Hospital of Jilin University were retrospectively analyzed. Three different staging methods were used.@*Results@#With increase in the classification level of the Bismuth-Corlette classification, the radical resection rate did not significantly decrease (P>0.05). The radical resection rates of stage T1, T2 and T3 in the modified T-staging system were 60.0% (27/45), 36.0% (10/28) and 14.0% (9/65) respectively (all P<0.05). The radical resection rates of patients in the stages I, II, III, IV of the Mayo Staging System were 86.0% (12/14), 50.0% (14/28), 29.0% (19/66) and 3/0% (1/30) respectively (all P<0.05). The overall survival time were no significant differences between the different Bismuth-Corlette and the modified T-staging system patients (P>0.05). However, there were significant differences among the survival rates in the various tumor staging levels using the Mayo Staging System.@*Conclusions@#The modified T-staging system and the Mayo staging system were more accurate than the Bismuth-Corlette typing system in predicting radical resection rates in patients with hilar cholangiocarcinoma. The Mayo staging system was superior to the Bismuth-Corlette typing system and the modified T-staging system in predicting prognosis of patients with hilar cholangiocarcinoma.
