Forty three poor risk patients with liver malignant tumor ; 32 primary and 11 metastatic, were treated by ablation therapy. Twenty eight patients underwent microwave coagulation therapy (MCT); 15 patients experienced rediofrequency ablation therapy (RFA) according to tumor diameter, number and localization. One year survival rate of hepatocellular carcinoma (HCC) patients treated by RFA (90.9%, n = 13) was similar to that treated by MCT (91.7%, n = 19). Post opereative hospital days in RFA group was significantly shorter than that in MCT group because the later contained 2 cases of liver abcsses and 4 percutaneous cases of needle tract burn. Although RFA was acceptable as a mild and effective procedure, incomplete RFA followed by other treatments for early local recurrence was experimentted.Attension should be taken to use the two ablation procedures properly with comprehesion of their features.
