目的 通过对肺部实体肿瘤行射频消融 (radiofrequencyablation ,RFA)治疗结果的观察 ,评价其技术特点、安全性和疗效。方法 45例肺部实体肿瘤患者 ,病灶数共 5 4个 ,在CT引导下行经皮射频消融治疗 ,随访 2～ 6个月 ,常规行螺旋CT平扫和增强扫描来观察评价治疗结果。结果 RFA治疗后有 48个肿瘤组织发生凝固性坏死 ,CT表现为肿瘤去血管化征象或合并有体积缩小。 6个病变未能控制。结论 RFA作为肿瘤综合治疗的一部分 ,副作用小、安全 ,为较好的治疗恶性肺部局限性实体肿瘤的方法。
Objective To evaluate the technical characteristics, safety and curative effect of radiofrequency ablation (RFA) treatment of lung solid tumors. Methods Forty-five patients with solid tumors of the lung with a total of 54 lesions were treated with CT guided percutaneous radiofrequency catheter ablation. The patients were followed up for 2 to 6 months. Conventional spiral CT scan and contrast-enhanced scan were used to evaluate the treatment outcome. Results Forty-eight tumor tissues were coagulated and necrotic after RFA treatment. CT showed the signs of tumor de-vascularization or the shrinkage of the volume with the combination of them. Six lesions failed to control. Conclusion RFA as a part of comprehensive treatment of cancer, side effects of small, safe, for the better treatment of malignant pulmonary limited solid tumor approach.
