Abstract
To assess the survival of radiofrequency ablation (RFA) and investigate the prognostic factors affecting overall survival, local recurrence-free survival and disease-free survival in hepatocellular carcinoma (HCC). A total of 192 HCC patients underwent RFA treatment in our department and were enrolled into this study. Among them, 151 patients were males and 41 were females (mean age, 59.2 years, range, 24 - 87 years old). The average tumor size was (3.9 +/- 1.3) cm (range, 1.2 - 8.0 cm). Of these 192 HCC patients, their Child-Pugh grade of A, B and C were 106, 77 and 9, respectively. According to UICC-TNM system, 57, 85, 44 and 6 patients were in stage I, II, III and IV respectively. Kaplan-Meier model and log-rank test were used in univariate analysis and COX regression model was used in multivariate analysis to identify prognostic factors for survival. The 1-, 2-, 3- and 4-year overall survival were 84.9%, 69.1%, 60.4% and 52.8%, respectively. Local recurrence-free survival were 75.1%, 53.8%, 43.9% and 40.8%, respectively. Disease-free survival were 64.3%, 43.2%, 37.1% and 25.0%, respectively. The following factors were identified as independent prognostic factors for survival by multivariate model: (1) Overall survival: Chil...Continue Reading
