Microwave Ablation Simultaneously Combined With Lenavatinib for Recurrent Hepatocellular Carcinoma

Microwave ablation (MWA) is available as the major curative treatments for early-stage recurrent HCC. Lenvatinib was non-inferior to sorafenib in overall survival in untreated advanced hepatocellular carcinoma. No study has evaluated MWA simultaneously combined Lenvatinib for recurrent HCC. There needs further investigation to explore the efficacy and safety of the combination treatment. Thus, the investigators carried out this randomized, multicenter, prospective trial study to find out it.

Inclusion criteria
