ABSTRACT
Objective To analyze the prognostic factors of survival in patients with huge hepatocel lular carcinoma (HCC) who underwent hepatectomy with a view to improve treatment efficacy.Methods A retrospective study was conducted on 124 patients with huge hepatocellular carcinoma who underwent hepatectomy for HCC from January 2004 to December 2010 in our hospital.Univariate and multivariate analyses were performed using statistical software (SPSS 19.0 for Windows) to identify independent prognostic factors.Results The cumulative 1-,3-and 5-year survival rates of the 124 patients were 65.1％,35.8％ and 25.1％ respectively.The mean survival and the median survival were 34.7 and 26.0 months respectively.In the 65 patients who underwent curative resection,the 1-,3-and 5-year disease-free survival rates were 40.2％,19.3％ and 7.1％ respectively.The mean disease-free survival and the median disease-free survival were 18.6 and 9.0 months respectively.Univariate analysis showed HBsAg,tumor capsule,liver cirrhosis,vascular invasion,tumor rupture,intrahepatic metastasis,curative resection and BCLC staging significantly affected postoperative survival(P ＜ 0.05).The Cox multivariate analysis indicated HBsAg,liver cirrhosis,curative resection and intrahepatic metastasis were independent prognostic factor (P ＜ 0.05).Conclusions Intrahepatic metastasis,liver cirrhosis and HBsAg were prognostic factors influencing survival outcome of huge HCC in patients after hepatectomy.Improving curative resection rate of huge HCC significantly extended survival for these patients.
