Differences between microwave coagulation and radiofrequency ablation for patients with hepatocellular carcinoma who received laparoscopic thermal ablation therapies

Abstract

Differences of effect between microwave coagulation and radiofrequency ablation for patients with hepatocellular carcinoma who received laparoscopic thermal ablation therapies, have not been found in the previous report. In our institution, we select MCT or RFA in accordance with location of HCC. Usually, we select RFA when HCC are located at head side of liver and select MCT when HCC are located at caudal side (near organs) of liver. Thus, we investigate the differences between patients who were treated by MCT and RFA. As results, the longest diameter of HCC was larger in RFA patients than in MCT patients. And, the number of patients who had HCC at S3 was larger in RFA group than in MCT group. The efficacy was not different between MCT and RFA.
