摘要 目的 观察松果体区肿瘤放射治疗的效果。方法 6年间共收治松果体区肿瘤患者24例,20例患者放疗前行脑室腹腔分流术。放射源为6mvx线,放射野:6x6~6x8cm^2,放射DT22~24GY+全脑照射33~36GY17例。单用6x6~6x8cm^2野照射DT60GY7例。结果 (1)近期疗效:头痛症状完全消退89%,视力改善率为33%。(2)远期疗效:五年生存率58.2%。结论 (1)松果体区肿瘤手术及取病理较困难。其治疗以放疗为主。先用局限野照射,视肿瘤退缩情况决定是否全脑照射,是一种较好方法,放疗剂量应给足55~60GY。(2)对伴有颅高压症状者放疗前先行脑室腹腔分流术是值得推广的。
