使用伽玛刀治疗脑膜瘤病人５２例，随访２８例，随访时间２～２２个月。治疗后８例肿瘤体积缩小，１８例体积不变，２例肿瘤增大；一年后肿瘤生长控制率为９２％。９例出现治疗后放射性脑水肿，包括颅底肿瘤２例，非颅底肿瘤７例。讨论了伽玛刀治疗脑膜瘤的适应症及疗效，认为伽玛刀对肿瘤位于颅底或身体不能耐受手术者是一种较安全有效的方法。
52 patients with meningioma were treated with gamma knife and 28 patients were followed up for 2-22 months. After treatment, the tumor volume was reduced in 8 cases, the volume in 18 cases was unchanged, and the tumors in 2 cases increased; the control rate of tumor growth was 92% after one year. Radial brain edema occurred in 9 patients after treatment, including 2 skull base tumors and 7 non-cranial base tumors. The indications and efficacy of Gamma Knife in the treatment of meningiomas were discussed. It is considered that Gamma Knife is a safe and effective method for tumors located in the skull base or the body can not tolerate surgery.
