研究目的:
Radiofrequency ablation is a popular treatment for recurrent hepatocellular carcinoma (HCC),but still has a higher recurrence. Sorafenib as neo-adjuvant therapy in combination of RFA was not reported yet. There's a theoretical advantage of this combination. Hence in this study the efficacy and safety of pre-administrative Sorafenib and Latter radiofrequency ablation (RFA) in Recurrent HCC will be tested in a multicenter prospective cohort study.
