超声引导下高风险区域肝癌的微波消融治疗

Ultrasound-guided percutaneous microwave ablation of hepatic cancer in high risk areas

目的评价超声引导下经皮微波消融治疗高风险区域肝癌患者的有效性和安全性。方法 2009年8月至2012年6月期间我院22例高风险区域肝癌患者接受附加特殊方法的超声引导下经皮微波消融治疗,观察术后疗效、复发率及并发症的发生。结果微波消融治疗后1次消融肿瘤完全坏死率86.4%(19/22),2次消融肿瘤完全坏死率100%;较严重的并发症发生率为9.1%(2/22),随访期间局部复发率为18.2%(4/22),其中2例死亡。结论针对高风险区域的肝癌采取适宜的附加方法,微波消融治疗是安全有效的。

Objective To evaluate the efficacy and safety of ultrasound-guided percutaneous microwaveablation for the patients with liver cancer in high risk areas. Methods During the period from Aug. 2009 to Jun. 2012 in our hospital, 22 cases of liver cancer patients in high risk areas were undergone additional special ultrasound-guided percutaneous microwave ablation, the curative effect, the recurrence rate and the incidence of complications were studied. Results After microwave ablation therapy, complete tumor necrosis rate of 1 time ablation was 86.4% （19/22）, complete tumor necrosis rate of 2 times ablation was 100%; serious complication rate was 9.1% （2/22）, the local recurrence rate in follow-up period was 18.2% （4/22）, of which 2 patients died. Conclusion Appropriate application of additional methods for high risk areas of liver cancer, microwave ablation is safe and effective.
