脑膜瘤来源于蛛网膜上皮细胞。占颅内肿瘤的15～20％。以良性者居多,其生长缓慢,常见于女性,临床表现为头痛、神经压迫症状。外科为主要治疗手段。放疗的地位一直不十分明了。然而手术死亡率以及术后复发率均较高。作者在法国巴黎德龙(Tenon)医院用放射治疗48例脑膜瘤。其中男:女=1:3.5。年龄最小13岁,最大79岁。照射技术采用二至四野外照射,4MV～25MV光子或光子加电子束,照射剂量为50～60Gy,分割方式为2.5Gy/次,每周4次。分以下各组:A组15例为完全切除术后放疗;B组10例系次全切
Meningioma comes from arachnoid epithelium. Accounting for 15 to 20% of intracranial tumors. Mostly benign, its slow growth, common in women, the clinical manifestations of headache, nerve compression symptoms. Surgery as the main treatment. The status of radiotherapy has not been very clear. However, surgical mortality and postoperative recurrence rates were high. The authors treated 48 patients with meningioma at a hospital in Tenon, Paris, France. Among them, male: female = 1: 3.5. The youngest 13 years old, the oldest 79 years old. Radiation technology using two to four field irradiation, 4MV ~ 25MV photon or photon plus electron beam irradiation dose of 50 ~ 60Gy, segmentation method for 2.5Gy / times, 4 times a week. Divided into the following groups: A group of 15 patients after complete resection of radiotherapy; B group of 10 cases of total subtotal
