The differing efficacies of radiofrequency ablation and microwave coagulation for hepatocellular carcinoma (HCC) are unknown. Therefore, we performed a multi-center study to assess the factors contributing to survival and local recurrences of HCC among patients with solitary tumors who underwent endoscopic thermal ablation as their primary treatment. ⋯ Differences in the effect on survival and local recurrence between microwave and radiofrequency were not observed in this retrospective, multi-center study of endoscopic thermal ablation for HCC.
