Interventions

Medical Device : For 1-3 cm small hepatocellular carcinoma, radiofrequency ablation (RFA) using Octopus electrode with combined dual switching monopolar and bipolar mode

and no-touch technique is performed. In the no-touch radiofrequency ablation (RFA), the electrodes are placed in the periphery of the tumor and radiofrequency ablation (RFA) is performed without punct

Inclusion criteria: (1) Patients who agreed to the protocol requirements and submitted consent (2) 20 years old-85 years old (3) Child-Pugh Class A or B7 (4) Among patients with cirrhosis, patients suspected of having HCC of 1-3 cm in size on MDCT or MRI performed within 60 days, and are going to undergo RFA

Exclusion criteria

Exclusion criteria: (1) When the number of malignant liver tumors is 2 or more (2) When the maximum size of the tumor exceeds 3 cm (diffuse carcinoma) (3) Patients with previous medical history of liver cancer who have recurrent liver cancer within 2 years (4) When the tumor adheres to the portal vein or hepatic vein of 5 mm or larger (5) When the tumor is not visible even under CEUS-fusion image guidance (6) severe liver failure (Child-Pugh class B8, B9 or C) (7) In case of invasion of hepatic vessels by HCC (8) Severe coagulopathy (if platelet is below 50,000/mm3, INR is over 50% prolongation) (9) When there is metastasis outside the liver (10) A situation where the probability of obtaining appropriate data suitable for the research purpose is very low
