摘要
目的：探讨MASEP-SRRS伽玛刀治疗脑转移瘤的疗效.方法：56例脑转移瘤采用MASEP-SRRS伽玛刀治疗、Gamma-plan计划系统规划治疗,边缘剂量18～25Gy,平均20Gy,靶点中心剂量32～60Gy,靶点数3～9个,平均5个,随访时间3～32个月.结果：获得随访52例,治疗有效率92.3%（48例）,消失53.8%（28例）,缩小并强化程度减弱15.4%（8例）,转移瘤大小不变但中间出现坏死23%（12例）,未出现严重并发症.结论：旋转式伽玛刀治疗脑转移瘤安全、有效.
Objective： To estimate the efficacy of rotary gamma-knife radio-surgery in the treatment of brain metastases, Methods： Fifty six patients with brain metastases were treated by MASEP-SRRS rotary gamma-knife, and were followed from 3 months to 32 months. Each of the cases had 5 targets on average （3 to 9）. The dosage in the edge of the target were 18 to 25 Gy （mean= 20 Gy）, that in the centre were 32 to 60 Gy. Results：Fifty two patients were followed up, which of effective rate were 92.3%（48 cases）. The tumor body disappeared in 53.8% of all cases （28 cases）, strengthen and extent diminishing in 15.4% （8 cases）, had no change but taken place necrosis in the center in 23% （12 cases）. There were no serious complications. Conclusion： Gamma knife radio-surgery in the treatment of brain metastases was effective and safe.
