目的 探讨在CT引导下采用经皮射频消融治疗术治疗肺癌的疗效、适应证、特点及其安全性。方法 应用RF 2 0 0 0型射频治疗仪 ,对 4 0例肺癌患者在CT引导下进行 6 2次经皮射频消融治疗 ,随访观察肿瘤毁损情况、并发症及肺功能的变化。结果 肿瘤直径 <5cm者 ,完全毁损率为 6 9.5 7% (16 / 2 3) ;肿瘤直径为 5～ 10cm者 ,完全毁损率为 5 2 .94 % (9/ 17)。余 15例中 ,12例经 2次治疗后部分毁损 ,3例无效。并发症发生率 15 % (6 / 4 0 )。结论 经皮射频消融治疗肺癌具有安全及副作用小等特点 ,是一种较好的治疗肺癌的方法。
Objective To investigate the efficacy, indications, characteristics and safety of percutaneous radiofrequency catheter ablation for the treatment of lung cancer under CT guidance. Methods A total of 40 radiofrequency ablation radiofrequency (RF) 2000 radiofrequency ablation devices were used to treat 42 lung cancer patients undergoing CT guided radiofrequency catheter ablation. Sixty patients underwent percutaneous radiofrequency ablation (RFA). The tumor damage, complications and pulmonary function were observed. Results The complete tumor destruction rate was 6 9.5 7% (16/2 3) for tumor diameter <5 cm. The tumor diameter was 5 to 10 cm and the complete destruction rate was 52.94% (9/17). Of the remaining 15 cases, 12 were partially damaged after 2 treatments and 3 were ineffective. The complication rate was 15% (6/40). Conclusion Percutaneous radiofrequency ablation of lung cancer with safety and side effects is small, is a better method of treatment of lung cancer.
