Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Patients with recurrent hepatocellular carcinoma after locoregional treatment

Arm Description

Patients with chronic liver disease have recurrent hepatocellular carcinoma which is diagnosed on contrast-enhanced computed tomography (CT) or magnetic resonance imaging (MRI).

Outcomes

Primary Outcome Measures

Local tumor progression rate
Evaluate local tumor progression by follow-up computed tomography (CT) or magnetic resonance imaging (MRI) with alpha-fetoprotein (AFP) level

Secondary Outcome Measures

Safety margin evaluation
Evaluate the safety margin around the index tumor on immediate computed tomography (CT)
Technical success rate
Evaluate technical success defined as complete ablation of the index tumor on 1 month follow-up computed tomography.

8. Arms, Groups, and Interventions

Arm Title
Patients with recurrent hepatocellular carcinoma after locoregional treatment
Arm Type
Experimental
Arm Description
Patients with chronic liver disease have recurrent hepatocellular carcinoma which is diagnosed on contrast-enhanced computed tomography (CT) or magnetic resonance imaging (MRI).
Intervention Type
Procedure
Intervention Name(s)
Radiofrequency ablation using combined bipolar and monopolar energy deliver with Twin Cooled-Wet electrodes
Intervention Description
Radiofrequency ablation will be performed by using twin cooled-wet electrodes. Two electrodes will be places on the tumor under ultrasonography (US)-computed tomography (CT)/magnetic resonance (MR) fusion tool guidance. The electrodes will be cooled with saline, and radiofrequency (RF, bipolar mode and switching monopolar mode) will be applied to two electrodes at the same time for about 6 to 30 minutes depending on the tumor size. The temperature will be maintained at 90-100 °C. The RF energy will be delivered by using the 200 watts single generator.
Primary Outcome Measure Information:
Title
Local tumor progression rate
Description
Evaluate local tumor progression by follow-up computed tomography (CT) or magnetic resonance imaging (MRI) with alpha-fetoprotein (AFP) level
Time Frame
12 months after radiofrequency ablation
Secondary Outcome Measure Information:
Title
Safety margin evaluation
Description
Evaluate the safety margin around the index tumor on immediate computed tomography (CT)
Time Frame
Immediately after radiofrequency ablation
Title
Technical success rate
Description
Evaluate technical success defined as complete ablation of the index tumor on 1 month follow-up computed tomography.
Time Frame
1 month after radiofrequency ablation
