Combination transarterial chemoembolization and radiofrequency ablation therapy for early hepatocellular carcinoma.

The combination treatment group had significantly better long-term survival rates than the RFA group, and showed a trend favoring an OS benefit compared to the TACE group; however, significant differences between the RFA and TACE groups were not observed ( p = 0.044, p = 0.046, and p = 0.771, respectively, based on log-rank test) ( Fig. 3 ).
