About this trial

This is an interventional treatment trial for Hepatocellular Carcinoma

Eligibility Criteria

20 Years - 85 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Child-Pugh class A or B7.
  • Presence of chronic hepatitis B or liver cirrhosis.
  • Patients with hepatocellular carcinomas diagnosed by histopathology or noninvasive imaging-based diagnosis according to the Korean Liver Cancer Association-National Cancer Center Korea guidelines.
  • Patients with viable hepatocellular carcinoma after locoregional treatment diagnosed by the Liver Imaging Reporting and Data System.
  • Tumor location is less than 5 cm from liver capsule.

Exclusion Criteria:

  • The number of tumor is three or more.
  • Tumor size is over 3 cm.
  • Tumor location is over 5 cm from liver capsule.
  • Child-Pugh class B8-9 or C.
  • Presence of macrovascular invasion and/or distant metastasis.
  • Platelet count < 50,000 mm3, or international normalized ratio > 1.5 (prothrombin time >1.5 × normal).

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Patients with hepatocellular carcinoma (equal or less than 3 cm)

Arm Description

Under the guidance of multimodality-ultrasound (US) fusion image, one of the three electrodes was placed across the portal vein branch near the tumor, and the other two electrodes were placed around the tumor through the previously planned approach path. After placement of electrodes, the temperature is maintained at 90-100 degrees Celsius for about 6-30 minutes depending on the size of the tumor, using the combined energy transfer mode that sequentially adds the bipolar mode and/or the monopolar mode.

Outcomes

Primary Outcome Measures

Technical success
Technical success addresses whether the index tumor was treated according to a predefined protocol and entirely covered by the ablation zone.
Local tumor progression rate
Local tumor progression, defined as the appearance of tumor foci at the margin of the ablation zone after the attainment of treatment success.

Secondary Outcome Measures

Complication after radiofrequency ablation
Post-radiofrequency ablation complications were defined as problems noted within 1 month after RFA as well as additional complications identified on follow-up imaging and judged to be likely caused by radiofrequency ablation.
Recurrence-free survival
Recurrence-free survival was defined as the interval between radiofrequency ablation and the date of any type of recurrence or the last follow-up date if there was no recurrence.

Arm Title
Patients with hepatocellular carcinoma (equal or less than 3 cm)
Arm Type
Experimental
Arm Description
Under the guidance of multimodality-ultrasound (US) fusion image, one of the three electrodes was placed across the portal vein branch near the tumor, and the other two electrodes were placed around the tumor through the previously planned approach path.

Intervention Type
Procedure
Intervention Name(s)
Radiofrequency ablation
Intervention Description
Radiofrequency ablation is performed for peripherally located small hepatocellular carcinoma using combined energy delivery mode and triple cooled-wet electrodes. One of three electrodes is placed across the 4th or 5th portal vein branches near the target tumor which enables anatomical ablation of tumor.
Primary Outcome Measure Information:
Title
Technical success
Description
Technical success addresses whether the index tumor was treated according to a predefined protocol and entirely covered by the ablation zone.
Time Frame
Immediately after radiofrequency ablation
Title
Local tumor progression rate
Description
Local tumor progression, defined as the appearance of tumor foci at the margin of the ablation zone after the attainment of treatment success.
Time Frame
12 months after radiofrequency ablation
Secondary Outcome Measure Information:
Title
Complication after radiofrequency ablation
Description
Post-radiofrequency ablation complications were defined as problems noted within 1 month after RFA as well as additional complications identified on follow-up imaging and judged to be likely caused by radiofrequency ablation.
Time Frame
Immediately, 1 month, 3 months, 6 months, 9 months, and 12 months after radiofrequency ablation
Title
Recurrence-free survival
Description
Recurrence-free survival was defined as the interval between radiofrequency ablation and the date of any type of recurrence or the last follow-up date if there was no recurrence.
Time Frame
12 months after radiofrequency ablation
