肝細胞癌における熱凝固療法の適応と成績

Abstract

We analyzed the rates of survival, non-local recurrence, and non-another recurrence of 89 patients with solitary hepatocellular carcinoma who underwent thermal ablation therapies as primary treatment (naive patients). Thirty five cases were ablated by percutaneous radiofrequency ablation (PRFA), 32 and 22 were treated by laparoscopic microwave coagulation (LMCT) and by percutaneous microwave coagulation (PMCT), respectively. Five-year survival rates were 87%, 60%, and 82% in PRFA, LMCT, and PMCT, respectively, with no statistical significance. Rates of 5-year non-local recurrence were 60%, 74%, and 51% in PRFA, LMCT, and PMCT, respectively, with no statistical significance. Those of 5-year non-another recurrence were 0%, 19%, and 20%, with no statistical significance.Thus, PRFA, LMCT, and PMCT had same effectiveness for the local treatment of HCC.
