ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the clinical values of ultrasound-guided percutaneous composite thermal ablation technique in the treatment of medium and large hepatocellular carcinoma (HCC).</p><p><b>METHODS</b>By the composite technique of multiple-needle insertion and multi-point energy application, ultrasound-guided percutaneous radiofrequency ablation (RFA) or microwave ablation (MWA) were employed to treat 68 patients of HCC with tumor nodule > or = 3.1 cm in diameter. There was a total number of 73 tumor nodules, with a mean diameter of (4.5 +/- 1.7) cm (3.1-13.0 cm). Sixty-three patients had single tumor nodule, and the remaining 5 had 2 nodules. With a follow-up time of 1.9 - 67.6 months [(16.0 +/- 14.8) months], the local and long-term efficacy was analyzed.</p><p><b>RESULTS</b>Hepatic subcapsular hematoma were found in 1 patient. And skin burning in 1 patient 1. Complete ablation rate was 78.1% (57/73), local tumor progression was presented in 24.6% tumor nodules (14/57) and distant recurrence developed in 56.7% patients (38/67). The 1-, 3-, 5-years survival rate was 62.3%, 29.6% and 21.6%, respectively, with a median survival time of 18.6 months, (95% confidence interval 10.9 months, 26.3 months). There were no remarkable differences in complete ablation rate, local tumor progression, distant recurrence rate and survival rate between RFA and MWA.</p><p><b>CONCLUSIONS</b>By the composite ablation technique, ultrasound-guided percutaneous thermal ablation was effective in treating medium and large unresectable HCC. And the advantage is minimal invasiveness. RFA and MWA had no marked differences in terms of therapeutic efficacy.</p>
