目的探讨陀螺旋转式钴60立体定向放射治疗系统(陀螺刀)治疗脑胶质瘤的方法和疗效。方法应用上海伽玛星科技发展有限公司的GMX B型陀螺旋转式钴60立体定向放射治疗系统,治疗31例脑胶质瘤患者,肿瘤直径0.9~9.0 cm,多靶点联合照射,处方剂量周边2520~4540 cGy,中心5040~9099cGy,单次剂量300~500cGy,1次/日,5次/周,一疗程5~13次。结果随访3~6个月,按实体瘤疗效WHO评价标准,完全缓解(CR)2例,占6.45%,部分缓解(PR)8例,占25.80%,稳定(SD)17例,占54.84%,进展(PD)2例,占6.45%,总有效率83.70%。结论陀螺刀治疗脑胶质瘤有效,可临床应用。
Objective To investigate the method and efficacy of gyro-rotating cobalt 60 stereotactic radiotherapy system (gyro knife) in the treatment of glioma. Methods GMG B gyroscope cobalt 60 stereotactic radiotherapy system of Shanghai GammaStar Technology Development Co., Ltd. was used to treat 31 patients with glioma. The tumor diameter was 0.9-9.0 cm. 2520 ~ 4540 cGy, the center of 5040 ~ 9099cGy, a single dose of 300 ~ 500cGy, 1 times / day, 5 times / week, a course of 5 to 13 times. Results The follow-up was 3 to 6 months. Two patients (6.4%) had complete remission (CR), 8 had partial response (PR), 25.80% had complete remission (CR), 17 had stable disease (SD) , Progress (PD) in 2 cases, accounting for 6.45%, the total effective rate was 83.70%. Conclusion Gyro knife treatment of glioma effective, clinical application.
