国际抗癌联合会(UICC)的TNM分期作为判断巨块型肝内胆管癌预后的标准为人们广泛接受,但胆管壁浆膜侵犯并不是该分期的判定指标。日本肝癌研究组将胆管壁浆膜侵犯列入UICC的TNM分期中的T标准中,建立了新的TNM 分期标准。为研究胆管壁浆膜侵犯是否对巨块型肝内胆管癌术后生存率有影响,为了解新的TNM分期法能否更为准确 The International Union Against Cancer (UICC) TNM staging is widely accepted as a criterion for judging the prognosis of massive intrahepatic cholangiocarcinoma, but serosal invasion of the bile duct wall is not an indication of this stage. Japanese liver cancer research group will be included in the bile duct wall serosal invasion UICC TNM staging in the T standard, established a new TNM staging criteria. To study whether the invasion of bile duct serosal invasion of giant bile duct intrahepatic cholangiocarcinoma postoperative survival rate, in order to understand whether the new TNM staging method can be more accurate
