目的 探讨CT引导下I125粒子植入治疗肺癌的价值，观察肺癌患者的表现，研究技术的可行性和近期疗效。方法 将60例经细胞学确诊为肺癌的患者随机分为A组和B组:A组为125I粒子治疗组，共30例，采用CT引导植入治疗。B组为对照组，共30例，采用药物灌注。结果 治疗组的总有效率为82.3%,对照组的总有效率为52.6%。两者有统计学差异。结论CT引导下125I粒子治疗肺癌的近期疗效显著，治疗组效果优于对照组。

Objective To explore the clinical value of CT-guided 125I-seeds implantation for the treatment of lung cancer. Methods 20 cases of patients diagnosed with lung cancer were randomly divided into 125I-seeds implantation treatment group (Group A, 10 cases) and control group (Group B, 10 cases treated with drug perfusion). Results The total treatment effective rate in treatment group and control group were 82.3% and 52.6%, respectively. There was statistically difference between two groups. Conclusion The efficacy of CT-guided 125I seeds treatment for lung cancer was significantly better than the control group. The CT-guided 125I seeds implantation may play an important role in the treatment of lung cancer
