Abstract

We compared the efficacy of transcatheter arterial chemoembolization (TACE) in combination with CT-guided radiofrequency ablation (RFA) with that of surgical resection (SR) in patients with hepatocellular carcinoma (HCC) within the up-to-seven criteria. From January 2004 to December 2014, 420 multicenter consecutive patients with HCC who conformed to the up-to-seven criteria and initially received either TACE plus CT-guided RFA (TACE-RFA) or SR were enrolled. A matched cohort composed of 206 patients was selected after adjustment with propensity score matching. The overall survival (OS) of each patient was calculated with the Kaplan-Meier method and compared by the log-rank test. The median OS and 1-, 3-, and 5-year survival rates were 56.0 months, 96.1%, 76.7% and 41.3% in the TACE-RFA group and 58.0 months, 96.1%, 86.4% and 46.2% in the SR group, respectively. There was no significant difference in OS between the two groups ( = 0.138). For patients with HCC beyond the Milan criteria, TACE-RFA provided a longer median OS than SR (52.0 vs 45.0 months, = 0.023). Treatment by TACE-RFA conferred an OS rate comparable with that of SR in patients within the up-to-seven criteria. For patients with HCC between the Milan and the up-to-seven criteria, TACE-RFA might be superior to SR for survival prolongation.
