【摘要】 目的探讨¹²⁵I粒子近距离放射治疗复发脑胶质瘤的临床分析。方法将40例经手术切除后组织细胞学确诊,且术后复发的恶性胶质瘤患者（采取患者自愿原则）为A组,采用立体定向的方法将¹²⁵I粒子置入胶质瘤内,做肿瘤间质内放疗,同时配合直线粒子加速器放疗。B组以胶质瘤术后采用直线粒子加速器放疗20例患者为对照组。观察客观疗效,临床受益反应,毒性反应,并发症及生存情况。结果 6和12个月累积生存率两组为57.0%比32.6%和20.5%比12.5%（P<0.05）,中位生存时间两组为8.0比4.0个月,平均生存时间两组为8.5比5.5个月（P<0.05）。结论 ¹²⁵I粒子植入治疗脑恶性胶质瘤有疗效肯定,可延长患者生存期,无明显毒副作用,是一种安全有效的辅助治疗方法。更多还原

【Abstract】 Objective To study the role of ¹²⁵I seed interstitial irradiation with stereotactically implantation in the treatment of the recurrent gliomas.Methods Group A:40 cases as histological diagnosis after surgical resection,and recurrence of malignant glioma（patients to take a voluntary basis）,within the ¹²⁵ I into glioma with stereotactically,tumor interstitial radiotherapy,In conjunction with radiotherapy linear accelerator.Group B 20 patients with glioma after radiotherapy using linear particle accelerator as a control group.Observation of objective response,clinical benefit response,toxicity,complications and survival.Results The survival rates of 6 and 12 months time of two groups was 57.0%vs 32.6%and 20.5%vs 12.5%（P <0.05）.The median survival time of two groups was 8.0 months to 4.0 months（P < 0.05 ）.The average survival time of two groups was 8.5 months to 5.5 months（P < 0.05）.Conclusions ¹²⁵I seed interstitial irradiation with stereotactically implantation is effective and can prolong survival and improve quality of life, with no obvious toxicity.It is a simple,safe and effective method in the treatment of recurrent gliomas.更多还原
