CT引导下多弹头射频治疗晚期肺癌

目的：探讨多弹头射频（radiofrequency,RF)治疗晚期肺癌的疗效。方法：22例晚期肺癌患者在CT引导下进行RF治疗。结果：经过RF治疗，大部分患者痛有不同程度的缓解，19例患者术后CT示肿瘤内部空洞形成。3个月后20例患者行CT检查， 肺部肿瘤有不同程度的缩小，其中CR1例，PR12例，MR4例，SD3例。结论：CT引导下RF治疗肺部晚期肿瘤是一种安全、有效的微创治疗手段。

CT-guided radio-frequency ablation in the treatment of lung cancer

Objective To investigate the clinical results of radio-frequency ablation in the treatment of locally advanced lung cancer. Methods Twenty-two patients with locally advanced lung cancer were treated with radio-frequency ablation guided by CT. Results CT scan after radio-frequency ablation showed that there was cavity in the parenchyma of cancer. Most lung cancer patients felt remittent in chest pain in some extend. Follow-up CT scan in 20 patients revealed retraction of the treated region 3 months later after radio-frequency ablation. Out of the 20 patients, 1 had complete response, 12 had partial response, 4 had minor response, and 3 had stable diseases. Conclusion Radio-frequency ablation guided by CT is a promising minimally invasive technique in the treatment of locally advanced lung cancer.
