67例颅内星形细胞肿瘤临床病理分析

目的：探讨颅内星形细胞肿瘤的组织类型、分级与复发、预后的关系。方法：对６７例颅内星形细胞肿瘤的临床和病理资源进行统计分析。结果：免疫组织化学标记能帮助鉴定组织类型和颅内星形细胞肿瘤的分化程度。间质性星形细胞瘤和胶质母细胞瘤其术后２年、５年的生存率偏低（Ｐ〈０．００５）。结论：间变性星形细胞瘤和肥胖细胞星形细胞瘤更具恶性，易复发。胶质母细胞瘤在颅内肿瘤中恶性程度最高，预后差。

Clinicopathologic analysis of 67 cases intracranial astrocytic tumor

Purpose To explore the relationship among histological types, grading, recurrence and prognosis in patients of intracranial astrocytic tumor. Methods The clinical and pathological data of 67 cases of intracranical astrocytic tumor after surgical operation were analyzed. Results Immunohistochemical staining SP methods can help to definitude the histological type and differentiation of astrocytic tumor. Survival of 2 years and 5 years were lower in the patients of anaplastic astrocytoma and glioblastoma ( P <0 005). Conclusion The result suggest that anaplastic astrocytoma and gemistocytic astrocytoma are more malignant and more recurrent. The malignant degree of glioblastoma is very high and its prognosis is more poorer.
