摘要 目的从肿瘤控制率、并发症、剂量选择等几方面对伽玛刀治疗脑膜瘤进行探讨。方法1997年10月至2001年12月141例脑膜瘤经伽玛刀治疗。其中46例有开颅手术史,95例为初发。治疗前肿瘤容积为0.8~49.7cm33,平均15.9cm33。采用35~50%的等剂量曲线,边缘剂量为10~20Gy,平均为13.3Gy,中心剂量为24~40Gy,平均为30.7Gy,等中心点为1~14Gy。结果83例获得影象学随访资料,随访率为58.9%(83/141),随访时间为14~78个月,平均32.8个月,其中肿瘤消失25例(30.1%),缩小42例(50.6%),无变化6例(7.2%),增大10例(12.1%),肿瘤控制率为88%。结论伽玛刀是一种安全有效的治疗脑膜瘤的手段。
