Satoh typing for tumor thrombi in hepatocellular carcinoma with tumor thrombi in the bile duct / 中华普通外科杂志

ABSTRACT

Objective To evaluate Satoh typing for tumor thrombi in the bile duct in patients of hepatocellular carcinoma.Methods A retrospective analysis was made on clinical data of 51 hepatocellular carcinoma patients with tumor thrombi in the bile duct undergoing hepatectomy in Eastern Hepatobiliary Surgery Hospital from Jan 2004 to Dec 2005.The cumulative disease-free survival by the three Satoh types were compared by Kaplain-Meire analysis.and log-rank test.Results There was no operationrelated motality and the postoperative complication rate was 22%(11/5 1).The overall survival rates at 1-and 2-years were respectively 76%(39/51)and 55%(28/51).The overall disease-free survival rates at 1-and 2-years were respectively 53%(27/51)and 22%(11/51).The disease-free survival rates at 1-and 2-years in type Ⅰ patients were respectively 61%(19/31)and 29%(19/31).The disease-free survival rates at 1-and 2-years in type Ⅱ and Ⅲ patients were respectively 35%(7/20)and 10%(2/20).The cumulative disease-free survival rates at 2-years was statistically different between type Ⅰ,type Ⅱ and Ⅲ (v=7.489,P=0.006)).Conclusions Satoh typing of tumor thrombi helps to determine the surgery plan and assess the prognosis of hepatocellular carcinoma with tumor thrombi in the bile duct.
