摘要
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。
From October 1995 to July 1997, 52 cases of meningioma were treated with gamma knife radiosurgery. Twenty-eight cases were followed up by CT or MR. The follow-up period was from 2 to 22 months. Follow-up imaging evaluation showed tumor size shrinkage in 8 cases, central density decrease in 10 cases, no change in 8 cases and tumor volume increase in 2 cases. The actual 1year tumor growth control rate was 92%. Radiationinduced edema was noted in 9 cases, including 7 cases of the nonbasal tumor and 2 cases of basal one. The indications and efficacy of gamma knife treatment of the meningioma were discussed. Our preliminary experience suggests that gamma knife is an effective and safe technique for carefully selected patients with meningiomas.
