近年,由于诊断技术的改进,使脑肿瘤术后放疗病人的存活率有所提高。美国脑瘤研究小组的材料指出,胶质瘤的术后放疗有肯定的疗效,术后不照射的病人平均存活18周,术后全脑照射6000rad/6w平均存活42周。本文报告了欧州放疗中心1957-1978年收治的143例各级星形细胞瘤术后放疗的结果,全部均经组织学证实,其中Ⅰ级1例,Ⅱ级27例,Ⅲ级41例,Ⅳ级74例。Ⅰ级的1例不予分析,其余142例最少随访1年。男∶女=6∶4,平均年令:Ⅱ级:32岁,Ⅲ级41岁,Ⅳ级:49岁。所有病人均行脑瘤部分切除后放疗,3例于术后6个月放疗,其余均于术后2周放疗。1969年前收治的33例用250KVX-Ray,1969年以后均用60Co照射。其中86例照射量为
In recent years, due to the improvement of diagnostic techniques, the survival rate of postoperative radiotherapy patients with brain tumors has increased. The American brain tumor research team’s material pointed out that the postoperative radiotherapy of glioma has a certain effect, the average survival of patients who were not irradiated after surgery for 18 weeks, postoperative whole brain irradiation 6000rad / 6w average survival of 42 weeks. This paper reports the results of postoperative radiotherapy of 143 astrocytomas at all stages of the European Radiotherapy Center from 1957 to 1978. All of them were confirmed by histology. There were 1 case of grade Ⅰ, 27 cases of grade Ⅱ, 41 cases of grade Ⅲ, 74 cases. One case of grade I was not analyzed and the remaining 142 cases were followed up for at least one year. Male: Female = 6: 4, the average annual order: Ⅱ grade: 32 years old, Ⅲ grade 41 years old, Ⅳ grade: 49 years old. All patients underwent partial excision of brain tumor after radiotherapy, 3 patients received radiotherapy 6 months after operation, and the rest were treated with radiotherapy 2 weeks after operation. 33 cases treated before 1969 with 250KVX-Ray, 60Co irradiation after 1969. Of which 86 cases were irradiated
