Rescue therapy for local tumor progression after radiofrequency ablation of small hepatocellular carcinoma: a comparison between repeated ablation and transcatheter arterial chemoembolization

To compare the therapeutic outcomes of repeated radiofrequency ablation (RFA) and transcatheter arterial chemoembolization (TACE) as rescue therapy for the treatment of local tumor progression (LTP) after initial RFA for hepatocellular carcinoma (HCC).
