A clinical investigation on factors influencing the prognosis of primary liver cancer patients after hepatectomy / 中国普通外科杂志

ABSTRACT

Objective To explore factors influencing the prognosis of hepatocellular carcinoma (HCC) patients after hepatectomy. Methods From May 1994 to January 1998, 189 patients who underwent hepatectomy for HCC were enrolled for reviewing their clinical characteristics, treatment and prognosis. Twenty-two parameters contributing to long-term survival rate (SR) and disease-free SR were analysed. Results The 3,5-year cumulative SR of the whole group was 63%,45%, respectively. The 3,5-year SR and disease-free SR in the curative resection (CR) group ( n =162) were 67%,47% and 45%,26% respectively. Results showed that the way by which a tumor was found, tumor size, portal tumor thrombi, satellite nodule, TNM stage, cirrhosis type, recurrent and treatment, blood transfusion, differentiation grade,and CR were risk factors by individual variable analysis( P =0.0000～0.0034); A multivariable analysis showed that CR, tumor size, tumor finding mode and reoperation were significant factors associating with prognosis( P =0.0000～0.0024). Blood transfusion and type of cirrhosis were closely correlated with tumor-free survival ( P =0.0001). Conclusions Curative resection, tumor size, reoperation for recurrence were important factors for recurrence by multivariate analysis. The severity of concomittant liver cirrhosis and perioperative blood transfusion were closely correlated with postoperative tumor free survival.
