Value of Ultrasound-guided Radiofrequency Ablation Treatment with Micro-invasion for Hepatic Carcinoma

Objective To evaluate the efficacy of ultrasound-guided radiofrequency ablation for treatment of hepatic cancinoma.Methods The 66 tumors in 50 patients with hepatic carcinoma were treated with radiofrequency ablation.Contrast-enhanced Ultrasound were used to evaluate efficacy of RFA.All patients had been followed up for two years.Results CEUS was examined after RFA treatment in 66 tumors.The part 11 tumors ≥5 cm had enhanced.They were treated again with RFA.The 55 tumors were not enhanced in all stages of CEUS.Survival rate for one year was 93.5% (29/31),and two years was 87.1% (27/31) to 31 patient of tumors ≤3 cm.Survival rate for one year was 84.2%(16/19),and two years was 68.4%(13/19)to 19 patients of tumors3 cm.Conclusion Ultrasound-guided radiofrequency ablation is a micro-invasive,fewcomplications safe,convenient and effective technique in the treatment of hepatic cancionma.
