1962—1980年美国麻省总医院收治了26例脊髓髓内胶质瘤(9例星形细胞瘤,5例胶质母细胞瘤和12例室管膜瘤),其中24例接受了放射治疗(放疗加其他治疗者21例。另3例为放射疗术后复发性肿瘤)。考虑到慢性放射性脊髓病常始见于放疗后近乎1年时,本文选其完成放疗后随访至少一年的19例进行了分析。剔除的5例在最后一次随访时神经功能均有改善并全无进行性早期放射性脊髓病症状。19例在放疗前、后和最近一次随访时均有详细的神经系统检查记录,每例的脊髓剂量均进行了γ→rad 和常压→超高压的校正,并记录了分割次数放射总天数。作者用近年强调分割次数的三个
Twenty-six cases of intramedullary glioma (9 cases of astrocytoma, 5 cases of glioblastoma and 12 cases of ependymoma) were treated in the Massachusetts General Hospital from 1962 to 1980, and 24 of them received radiation therapy (Radiotherapy plus other treatment in 21 cases and the other 3 cases of recurrent tumor after radiotherapy). Taking into account the chronic radiation-induced spinal cord disease often seen almost 1 year after radiotherapy, the selection of its completion of radiotherapy at least one year after the follow-up of 19 cases were analyzed. Five of the patients who were excluded had improved neurological function at the last follow-up and had no progressive symptoms of early radiation-induced spinal cord disease. Nineteen patients had detailed neurological examination records before and after radiotherapy and at the most recent follow-up. Each spinal dose was corrected for γ → rad and atmospheric pressure to ultrahigh pressure, and the total number of days of radiotherapy was recorded. In recent years, the author emphasizes the number of split three
