本文回顾124例原发性脑瘤的单纯放疗和术后放疗的5年生存情况。材料与方法：分析经术后病理或CT、MRI证实的124原发性脑瘤。8mv－x线或60Co常规分割全脑照射，中线剂量30～40Gy，局部追加照射DT10－20Gy。全脊髓预防照射DT25～30Gy。结果：5年生存率：全部切除者和部分切除者分别是7／13（53．4％）、8／23（34.8％）；放射剂量50～60Gy者好于低剂量组；胶质瘤、髓母细胞瘤、室管膜瘤分别为10/32（31.2％）、2／6（33．3％）、1／2。结论：病人生存期长短取决于手术切除程度、放射剂量与肿瘤组织学类型。
This article reviews the 5-year survival of 124 patients with primary brain tumor who received radiotherapy and postoperative radiotherapy. Materials and Methods: 124 primary brain tumors confirmed by postoperative pathology or CT or MRI were analyzed. 8mv-x line or 60Co conventional whole brain irradiation, midline dose of 30 ~ 40Gy, local additional radiation DT10-20Gy. The total spinal cord prevents radiation from DT25 to 30Gy. Results: 5-year survival rate: All resections and partial resections were 7/13 (53.4%) and 8/23 (34.8%) respectively; radiation doses of 50 to 60 Gy were better than low-dose groups; gliomas, The medulloblastomas and ependymomas were 10/32 (31.2%), 2/6 (33.3%), and 1/2, respectively. Conclusion: The length of survival depends on the degree of surgical resection, radiation dose, and histological type.
