胶质瘤约占原发性中枢神经系统肿瘤的 4 3 %～50 % [1,2 ] ,以星形细胞瘤最多见 ,手术切除是首选的治疗方法。由于胶质瘤常呈浸润性生长 ,大多与正常脑组织无明显的分界 ,手术难以做到真正的彻底切除。因此 ,施行以手术为主 ,术后辅助放疗、化疗的综合治疗方案显得尤为重要。Ⅰ Gliomas account for about 43% to 50% of primary CNS tumors [1, 2].

Therefore, the implementation of surgery-based, postoperative adjuvant radiotherapy, chemotherapy, comprehensive treatment program is particularly important. Ⅰ
