CT引导射频消融术治疗肺癌35例 张开贤 李苓 邢超 张开国 袁倩倩 郝崇礼 满其荣 王伟 杨森 山东滕州市中心人民医院肿瘤科 ，山东 滕州 277500 【摘要】　目的：探讨CT引导下射频消融术(RFA)治疗肺癌的疗效及安全性。方法：35例肺癌进行了CT引导下射频消融治疗，其中鳞癌12例，腺癌20例，鳞腺癌1例，大细胞癌2例。中央型肺癌4例，周围型肺癌31例。肿瘤直径≤3cm 6例，3～5cm 21例，5cm 8例。结果：射频消融过程中多数病灶阴影增大，边缘模糊，部分病灶出现蜂窝气泡样改变，术后3个月复查CT显示28个病灶缩小，其中CR1例，PR例27例，SD4例，PD3例，总有效率（CR+PR）为80.0%。术后少量咯血5例，气胸5例，轻度发热7例。结论：CT引导RFA治疗肺癌是安全有效的微创技术，值得推广应用。 【关键词】　肺肿瘤；射频消融术；放射学，介入性 CT-guided radiofrequency ablation in treating 35 cases of cancer Zhang Kai-xian, Li Ling, Xing Chao, Zhang Kai-guo,Yuan Qian-qian, Hao Chong-li, Man Qi-rong, Wang Wei, Yang Sen, Teng ying.

Methods: 35 patients with NSCLC were treated with CT guided RFA, which including 4 cases of central lung cancer and 31 cases of peripheral lung cancer, as well as in different pathology type and tumour size. Result: During the process of RFA, the volume of lesions in majority cases become lager , also with a fuzzy edge. Some lesions show bubble-like changes. After three months later, CT showed that 28 lesions reduced, including CR 1 cases, PR 27 cases, SD 4 cases and PD 3 cases.The total effective rate (CR + PR) was 80.0%.

Conclusion: CT guided RFA is a safe, effective and minimal invasive therapeutic method for lung cancer. 【KEYWORDS】lung neoplasms; radiofrequency ablation; radiology, interventional 射频消融术( radiofrequency thermal ablation，RFA)已经广泛地用于肝脏、肾脏、前列腺等实质性脏器肿瘤的治疗，并取得了理想的疗效[1-2]，近来射频开始用于治疗肺癌[3-5]。2007年8月至2009年10月，我们对35例非小细胞肺癌进行了多层螺旋CT引导射频消融术，取得一定疗效，现报告如下。 与方法 1.1 资料　本组患者共35例，男性23例，女性12例，年龄50～78 岁，中位年龄65岁。术前全部经CT引导下经皮穿刺活检获取病理学诊断，其中鳞癌12例
