目的：观察超声引导经皮双极射频消融治疗肝癌的局部疗效。方法选取我院2012年5月～2013年10月收治、以治愈性治疗为目的的24例肝癌患者32个病灶，对所有患者均采取超声引导下经皮双极射频消融进行治疗，术后1个月观察患者影像学（超声造影、增强CT或增强MRI）检查结果，以评价局部疗效，以后每3个月随访一次，以观察患者复发情况。结果病灶完全消融（CA）率96.9%（31/32），其中最大径＜3cm病灶CA率为100%（27/27），最大径≥3cm病灶CA率为80%（4/5）；原发性肝癌完全CA率95.7%（22/23），转移性肝癌CA率100%（9/9）。所有患者均未出现严重并发症及与手术相关的死亡。随访2～19个月，局部复发率为6.3%（2/32）远处复发率为33.3%（8/24）。结论超声引导下经皮双极射频消融治疗肝癌安全可靠、局部疗效确切，对小肝癌尤其明显。

Objective To observe the local therapeutic efficacy of ultrasound-guided percutaneous bipolar radiofrequency ablation for liver cancer.Methods 24 patients with 32 liver tumor nodules who were referred to our hospital from May,2012 to October,2013.All patients were treated with ultrasound-guided percutaneous bipolar radiofrequency ablation with curative intention. We Observed the local therapeutic efficacy of all patients within one month after the treatment.The imageological examination (Contrast-enhanced ultrasound,contrast-enhanced Computed Tomography or contrast-enhanced magnetic Resonance Imaging) were used to decide the local therapeutic efficacy.We obeserved the recurrence of the tumors through the follow-up of every three months.Results Complete ablation(CA)was achieved in 96.9%(31/32)of tumor nodules.The CA rate was remarkably higher in nodules ≤3 cm(100%,27/27)than that in nodules >3 cm(80%,4/5)(P<0.05).CA rate was 95.7%(22/23)for primary liver cancers and 100%(9/9)for metastatic liver cancers.There was no mortality associated with bipolar radiofrequency ablation. Patients were followed-up from 2-19 months.The local recurrence rates were 6.3%(2/32)and the distant recurrence rates were 33.3%(8/24).Conclusion Ultrasound-guided percutaneous bipolar radiofrequency ablation for liver cancer is a safe and effective method, especially for small liver cancers.
