胶质肉瘤(Gliosarcoma,GS)是一种罕见的中枢神经系统原发恶性肿瘤。GS细胞经免疫组织化学染色后,可形成胶质母细胞瘤与恶性纤维组织细胞瘤两种瘤巢团状区互相交错的图像。GS发病急剧,进展迅速,颅外转移较普通胶质瘤多见。手术切除肿瘤是本病最有效的治疗手段。GS对常规放、化疗不敏感,但当出现肿瘤颅外转移时,可作为有益的辅助治疗。
Gliosarcoma (GS) is a rare primary malignancy of the central nervous system. GS cells after immunohistochemical staining, the formation of glioblastoma and malignant fibrous histiocytoma two tumor nests were interlaced images. GS rapid onset, rapid progress, extracranial metastasis more common than ordinary glioma. Surgical removal of the tumor is the most effective treatment for this disease. GS is not sensitive to conventional radiotherapy and chemotherapy, but it can be used as adjuvant therapy when there is extracranial metastasis.
