CT定位下经皮穿刺射频消融治疗肺肿瘤疗效分析

The feasibility and efficacy of percutaneous radio-frequency ablation in the treatment of pulmonary neoplasm

目的探讨CT引导下集束电极射频治疗肺恶性肿瘤的疗效。方法对1999年以来在CT定位引导下,采用WE7568集束电极射频肿瘤消融仪,用集束电极经皮穿刺到肺内肿瘤进行射频消融治疗,每针次温度75～95℃左右维持10min或15min。结果78例病人经CT引导行射频消融80例次,绝大多数病灶(77.4%)复查CT均有不同程度缩小或CT值下降30～37,疼痛等症状明显缓解。无严重并发症,无围手术期死亡。结论CT定位下经皮集束电极射频消融对肺恶性肿瘤的近期疗效明显,对晚期肺癌、多发性肺转移瘤及不能耐受手术者,可作为综合治疗的方法之一。

Objective To explore the feasibility and efficacy of percutaneous radio-frequency ablation through the guidance of computed tomography （CT） in the treatment of pulmonary neoplasm. Methods Using CT to localize the tumor and determine the optimal approach, WE＇7568 ablation needle was inserted into the target lesion. Radiofrequency was applied via the electrode for 10 or 15 min at 75 - 95℃. Results Total 78 cases were received 80 times of radio-frequency ablations through the guidance of CT. Reduced size of the pulmonary neoplasm and reduced chest CT number by 30 - 37 were founded in most cases （77.4%）. After the therapy, chest pain was alleviated in most cases. There was no severe complication and no case death. Conclusion Percutaneous radio-frequency ablation through the guidance of CT is one of feasible and effective treatment in unoperateble or late stage solid lung cancer.
