为探讨脑膜瘤术后复发的原因 ,对 1 7例复发脑膜瘤术后标本进行了光镜和电镜检查。电镜检查结果显示 ,1 7例复发脑膜瘤中有 9例瘤内部分细胞生长活跃 ,而光镜检查结果则显示 1 7例复发脑膜瘤仍为一般脑膜瘤结构表现。提示 :对复发脑膜瘤再次手术除力争全切外 ,还应对肿瘤的组织形态学做超微结构观察。对瘤细胞有生长活跃倾向的病例 ,建议术后辅以放射治疗 ,以控制或延缓肿瘤再次复发 ,延长病人生存期。
To explore the causes of recurrent meningiomas after surgery, 17 cases of recurrent meningiomas after surgery were examined by light microscopy and electron microscopy. Electron microscopy showed that 9 of 17 recurrent meningiomas had active intracerebral cell growth, whereas the light microscopic examination showed that 17 recurrent meningiomas were still normal meningiomas. Tip: Recurrence of meningioma surgery in addition to fight the whole cut, but also the tumor morphology should do ultrastructure observation. The growth of tumor cells tend to have the tendency of the case, it is recommended supplemented with radiotherapy after surgery to control or delay the recurrence of tumors to extend the survival of patients.
