NCT06682377

Brief Summary

The purpose of this study is to evaluate, through a prospective multicenter trial, the procedural time, safety, technical success rate for achieving a safety margin of at least 5 mm around the tumor, and the clinical efficacy (local and remote recurrence rates: estimated local recurrence rate at 12 months) of radiofrequency ablation using the "No-touch" technique. This approach employs Octopus electrodes and combined radiofrequency energy delivery (dual switching monopolar and bipolar mode) for the treatment of hepatocellular carcinoma.

Eligibility Criteria

Age20 Years - 85 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Agreement to the protocol requirements and provision of informed consent.
  • Age between 20 and 85 years.
  • Child-Pugh Class A or B7.
  • Patients with liver cirrhosis who are candidates for radiofrequency ablation (RFA) based on multi-detector computed tomography (MDCT) or multi-detector computed tomography (MRI) within 60 days, with a suspected hepatocellular carcinoma (HCC) lesion of 1-3 cm.
  • \*\*HCC Diagnostic Criteria:\*\* A. Presence of risk factors (e.g., hepatitis B virus (HBV) positive, hepatitis C virus (HCV) positive, liver cirrhosis).
  • B. Findings consistent with HCC on at least one imaging modality (MDCT, dynamic MRI, or Primovist MRI) according to the Korean Liver Cancer Association (KLCA) criteria.
  • C. Histological diagnosis of HCC.
  • No prior history of HCC treatment, or if previously treated, no recurrence confirmed for at least two years.

You may not qualify if:

  • Presence of three or more malignant liver tumors.
  • Diffuse infiltrative type tumors with unclear boundaries.
  • Recurrent HCC within two years of previous treatment.
  • Tumors adhered to major hepatic vessels or bile ducts by more than 5 mm.
  • Poor tumor visibility even with contrast-enhanced ultrasound (CEUS)-fusion image guidance.
  • Vascular invasion by malignant liver tumors.
  • Severe coagulopathy (platelets \<50,000/mm³ or International Normalized Ratio (INR) \>50% prolongation).
  • Presence of extrahepatic metastasis.
  • Situations where obtaining appropriate data for the study is unlikely.
