摘　　要：目的:探讨放射性125I粒子立体种植在盆腔转移瘤中的疗效。方法:通过三维粒子TPS系统确定粒子数量、针距、层距,CT引导下经皮穿刺永久性植入125I粒子在盆腔转移瘤内。结果:24例病人治疗后病灶不同程度缩小,疼痛程度明显缓解。结论:CT引导下永久植入125I粒子近距离治疗实体肿瘤具有微创、靶区剂量高、适形度好等优点,具有一定的临床价值。Objective：To investigate the curative effect of radioactive iodine - 125 interstitial brachytherapy in eavitas pelvis metastatic tumor. Methods：The patients were treated with 125I seed implantation by percutaneous surgery under CT guidance. The numbers, needle distance and coat distance of 125I seed were determined according to TPS. Results：After treating with 125I seed implantation, the size of tumor in 24 patients were reduced and their pain degree were relieved obviously. Conclusion： CT guided radioactive seed 125I implantation procedure has beneficial clinical effects in treating solid tumor with mininaal damage and high dose and conformal fields of target.
