The purpose of this study is to prospectively compare percutaneous radiofrequency ablation (RFA) versus percutaneous laser ablation (LA) for the treatment of small hepatocellular carcinoma in patients with cirrhosis.
Percutaneous ablation is a safe and effective therapy for cirrhotic patients with HCC when resection or liver transplantation is not possible. Among the various percutaneous local ablative therapies, radiofrequency ablation (RFA) has attracted the greatest interest because of its effectiveness and safety for single HCC ≤ 5.0cm or ≤3 HCC nodules ≤3cm. Some studies have shown that laser ablation (LA) may be as effective as RFA in the treatment of HCC. However, RFA and LA are different techniques and, in different cases (for example: size or site of HCC nodule), each of these procedures may have some advantages or disadvantages. Therefore there is the need for a prospective randomized controlled study to compare RFA and LA in patients with small HCC.

| percutaneous radiofrequency ablation | Procedure | Procedure: Radiofrequency ablation For RFA, we used a commercially available system (Valleylab, Tyco Healthcare, Boulder, CO, USA) and a 17-gauge "cool-tip" needle electrode with a 3cm exposed tip. The needle is inserted percutaneously under ultrasound guidance in the HCC nodule and treatment lasts 12 minutes. For nodules larger than 3cm in diameter, 2 insertions are used. In a period of six months, treatment may be repeated for no more than three times. When, after treatment, CT or MRI show a residual nodule activity of 10% or less, percutaneous ethanol injection may be done. If the residual activity is of 50% or more transarterial chemoembolization may be used. |
| Measure | Description | Time Frame |
|---|---|---|
| Tumor response | Complete ablation of the HCC nodule, defined as absence of contrast enhancement of the nodule at CT or MRI imaging | four weeks after treatment |
| Measure | Description | Time Frame |
|---|---|---|
| overall survival | Time from randomization to death. Patients alive at the end of follow-up are censored. | 12 months after last treatment |
| time to local recurrence | the time from complete tumor ablation to reappearance of arterial enhancement on CT or MRI either within a treated tumor or near its borders |
