The current role of radiofrequency ablation in the treatment of intrahepatic recurrent hepatocellular carcinoma.

The incidence of recurrent hepatocellular carcinoma (HCC) after initial curative treatments is relatively high. However, there is still the lack of standard management of recurrent HCC. Among several treatment modalities for primary HCC, radiofrequency ablation (RFA) seems to be more widely used for intrahepatic recurrent lesions. Therefore, we provide a comprehensive review of the current and novel application of RFA for recurrent HCC in all stages after curative treatment of primary HCC.
