摘　　要：目的 探讨经皮集束电极射频消融(radiofrequency ablation,RFA)对小肝癌(直径≤3cm)的治疗效果。方法利用RF-2000TM肿瘤射频治疗系统,在B超引导下对21例小肝癌患者24个肿块进行经皮肝穿刺射频热凝治疗,并用B超及CT检查以了解RFA治疗效果,随访观察其复发和生存情况。结果 RFA治疗后100％(20/20)的肿块血供消失(另4个治疗前即无血供),且2,4个肿块呈完全凝固性坏死(100％)。随访6月-3年,21侧中存活19例,半年生存率100％。存活的19例中,已有5例生存半年,4例生存1年,6例生存2年,4例生存3年。结论 集束电极RFA治疗小肝癌创伤小,安全,疗效可靠。Objective To evaluate the therapeutic efficiency of percutaneous cluster electrode radiofrequency ablation(RFA) for small hepatocarcinoma(diameter≤3cm). Methods 24 tumors in 21 patients with small primary hepatocarcinoma histologically confirmed were treated percutaneously under ultrasound guidance by RF-2000?cluster electrode radiofrequency ablation system. Ultrasound and CT were also used to evaluate the blood supply and coagulation necrosis in the treated tumors. Follow-up lasted from 6 menths to 3 years. Results Blood supply of tumors disappeared in 100% (20/20) tumors after RFA treatment (another 4 tumors had no blood supply before RFA). Complete coagulation necrosis could be found in all the 24 tumors(100%). 19 out of 21 cases survived in the subsequent follow-up period of 6 months to 3 years. Half-year survival rate was 100% . 5 cases survived for 6 months,4 for 1 year,6 for 2 years and 4 for 3 years. Conclusion RFA is minimally invasive,safe and effective in treating hepatocarcinoma .
