目的 分析CT引导下射频消融 治疗肺癌的影像学效果、并发症及存 活情况。方法 回顾性分析本院2013年 5月-2015年5月行CT引导下射频消融治 疗的76例肺癌的相关资料，观察比较射 频消融治疗前后影像学变化，并记录并 发症及随访1年存活率。结果 随访3个 月、6个月、12个月病灶局部控制率分 别为96.51%、93.02%、86.05%；治疗后 6个月肿瘤面积(13.26±3.14)cm2 ，CT值 (50.60±17.18）HU，均显著少于治疗前 的(11.52±4.82)cm2 、(35.74±12.35) HU，差异有统计学意义(P＜0.05)；术 中术后气胸发生率13.16%，发热发生率 17.10%，血痰发生率6.58%，无血胸等手 术相关严重并发症发生；1年无进展生存 率73.68%。结论 CT引导下射频消融治疗 肺癌效果好，并发症少，安全可行。

Objective To analyze the imaging effects, complications and survival of CT guided radiofrequency ablation for lung cancer. Methods The related data of 76 patients with lung cancer treated by CT guided radiofrequency ablation in our hospital during May 2013 to May 2015 were retrospectively analyzed. The imaging changes were observed and compared before and after radiofrequency ablation, and the complications and 1-year survival rate were recorded. Results In 3 months, 6 months and 12 months of follow-up, the local control rates of lesions were 96.51%, 93.02%, and 86.05% respectively. 6 months after treatment, the tumor area and CT value [(13.26±3.14) cm2 , (50.60±17.18) HU] were significantly smaller and lower than those before treatment [(11.52±4.82) cm2 , (35.74±12.35) HU] (P<0.05). The incidence rates of pneumothorax, fever and bloody sputum were 13.16%, 17.10% and 6.58%. There were no serious surgical complications related to hemothorax, and the 1 year progression free survival rate was 73.68%. Conclusion CT guided radiofrequency ablation is effective, safe and feasible in the treatment of lung cancer, and the complications are few.
