RFA for Small HCC With No-touch Technique Using Octopus Electrode

Radiofrequency Ablation for Small Hepatocellular Carcinoma Using Octopus Electrode and No-touch Technique: Preliminary Study

In this study, the investigators are going to prospectively compare the clinical outcomes (technical success rate, 12 month local tumor progression rate, complication rate, tumor seeding rate) of Radiofrequency ablation (RFA) with octopus electrode and no-touch technique for Hepatocellular carcinoma (HCC) to those of RFA with conventional tumor puncture method with the same device.

Inclusion Criteria:

• Child-Pugh class A
• patient with 1cm-2.5cm sized HCC
• 1 or 2 HCCs
• being referred for curative purpose of RFA
• sign informed consent

Exclusion Criteria:

• maximum tumor diameter greater than 2.5cm
• Child-Pugh class B or C
• more than 3 HCC lesions
• invisible tumor even after US/CT or US/MR fusion
• presence of vascular tumor thrombosis or extrahepatic metastasis
• severe coagulopathy (PLT < 50K, PT < 50% of normal range)
