作者对32例组织学证实为恶性胶质瘤的病人进行了脑内短距离治疗。男性24例,女性8例。半数以上年龄在50至69,发病高峰在60岁年龄组。12.5％的病人为未分化星形细胞瘤,87.5％的病人为多形性胶质瘤。全部病人均进行丁肿瘤切除,术后约两周,脑内髓入Cf-252放射源。此外还接受~(60)Co或6MevX线作全脑放疗。把3年内的临床试验分为三个阶段。第一阶段,应用单管植入,全脑照射5000至6000rad;第二阶段,应用多管植入,使肿瘤量达到6000rad,即是全脑照射4000～4500rad,缩野瘤床局部再增加1500至2000rad。第三阶段仍用多管植入,仅修改体外放疗技术,改全脑照射为部
The authors performed brainstem brachytherapy on 32 patients with histologically confirmed malignant glioma. 24 males and 8 females. More than half of the age ranged from 50 to 69 and the peak incidence was in the 60s. 12.5% of patients with undifferentiated astrocytoma, 87.5% of patients with pleomorphic glioma. All patients underwent resection of small tumors, about two weeks after surgery, the brain marrow Cf-252 radioactive sources. In addition to accept ~ (60) Co or 6MevX line for whole brain radiotherapy. The three-year clinical trial is divided into three stages. The first stage, the application of single-tube implantation, whole brain irradiation 5000-6000rad; the second stage, the application of multi-tube implantation, so that the tumor reached 6000rad, that is, whole brain irradiation 4000 ~ 4500rad, shrinkage tumor bed and then increase 1500 To 2000rad. The third stage is still multi-tube implantation, only modified in vitro radiotherapy technology, change the whole brain irradiation department
