Studies on the results of the percutaneous ablation therapy for hepatocellular carcinoma

Abstract

The outcomes of hepatocellular carcinoma treated with percutaneous ethanol injection therapy (PEIT), percutaneous microwave coagulation therapy (PMCT) and percutaneous radiofrequency wave ablation (PRFA) were compared. The cumulative 5-year survival rate was most favorable, at 92%, with PRFA, followed by PMCT, PEIT, and concomitant percutaneous ablation therapy in this order, at 61%, 50% and 30% respectively. However, as determined by modified Japan Integrated Staging score (mJIS), the outcome following PEIT was equivalent to that following PMCT. Due to the short observation period and small number of cases, it was not possible to accurately compare these therapies based on mJIS, but, the outcome with PRFA appeared similarly favorable.
