A single lesion was o bserved in 160/202 (79.2%), two lesions in 29/202(14.3%), and three lesions in 13/202 (6.4%) of patients. Results:Sixty-seven patients died. Survival rates were 80%at 12 months, 67%at 24 months and 57%at 30 months (Child-Pugh A 59% and Child-Pugh B 48%). By Cox regression analysis,survival was independently p redicted by serum albumin levels ≥35 g/L, platelet count ≥100.000/mmc, tumor s ize ≤3 cm, complete response at 1 month and Barcelona Clinic Liver Cancer (BCLC ) staging classification. Overall recurrence rates were 22, 38, and 44%at 12, 2 4, and 30 months, respectively.One procedure-related death occurred. The propor tion of major complications after treatment was 3.9%. Conclusions: A complete r esponse after RFTA significantly increases survival. The longest survival is obt ained in the presence of HCC ≤3 cm and of higher baseline albumin levels and pl atelet counts. BCLC staging classification is able to discriminate patients with good or poor prognosis.展开更多
