Abstract: Objeclive Different official guidelines recommend different treatment modalities for intermediate-and advanced-stage hepatocellular carcinoma (HCC). The aim of this study was to explore the safety and efficacy of hepatic resection(HR) in these patients. Methods Between 2000 and 2007,a consecutive sample of 1 259 patients with intermediate and advanced stage HCC who underwent HR (n=908) or transarterial chemoembolization (TACE,n=351) were included. Propensity score-matched patients were analyzed to adjust for any baseline differences. Results The 90-day mortality rates in the HR and TACE groups were 3.1% and 2.8% (P=0.827). The morbidity rate was significantly higher in the HR group (26.8%) than in the TACE group (18.5%,P=0.005). HR provided a survival benefit over TACE at 1,3,and 5 years (88% vs 81%,62% vs 33%, and 39% vs 16%,respectively;P<0.001). Propensity scoring and subgroup analyses based on tumor size,tumor number, presence or absence of macrovascular invasion,and portal hypertension (PHT) also showed that HR was associated with better long-term survival than TACE. Multivariate analyses revealed that alpha-fetoprotein ≥400 ng/ml, diabetes mellitus, macrovascular invasion,and PHT were independent predictors of poor prognosis. Conclusions For patients with HCC and Child-Pugh A liver function, the presence of a solitary large tumor,multin-odular tumors, macrovascular invasion,or PHT are not contraindications for HR. For these patients,HR provides better survival than TACE.
