目的了解长沙地区中枢神经系统 (CNS)肿瘤的发生特点及其临床病理特征。方法用常规方法分析了 12年间手术切除的 3 342例CNS肿瘤的构成及临床病理特点。结果CNS原发性上皮类肿瘤 (A组 ) 9种 ,2 35 0例 ,占总数的 70 .32 % ;其他类 (B组 ) 8种 ,6 6 3例 ,占 19.84% ;转移瘤 (C组 ) 12种 ,195例 ,占 5 .83 %和瘤样病变(D组 ) 5种 ,134例 ,占 4.0 1%。四组中最为常见的分别是星形胶质细胞瘤 (占A组的 46 .47% ) ,脑膜瘤 (占B组的 34.99% ) ,支气管肺癌 (占C组的 5 1.79% )和脑血管畸形 (占D组的 71.6 4% )。四组患者在年龄与性别比上有不同特点 ;B组年龄最高 ,平均为 42 .6 2岁 ,且转移瘤在颅内与椎管内的比值为 1.5 :1,分别占全部病例的 3 .5 % (117例 )和 2 .3 % (78例 )。结论长沙地区CNS肿瘤其病变构成与国外相比无明显地域差异 ,与国内报道的资料存在不同程度的相似性  Objective  To understand the occurrence and clinicopathological features of central nervous system (CNS) tumors in Changsha area.  Methods 构 Methods Conventional methods were used to analyze the composition and clinicopathological features of 3 342 CNS tumors resected over a 12-year period. Results 9CNS primary epithelial tumors (A group) 9 species, 2 35 0 cases, accounting for 70.32% of the total; other types (B group) 8 species, 6 6 3 cases, accounting for 19.84%; metastases (C group) 12 kinds, 195 cases, accounting for 5 .83% and tumor-like lesions (D group) 5 kinds, 134 cases, accounting for 4.01%. The most common of the four groups were astrocytoma (46.47% in group A), meningioma (34.99% in group B), bronchogenic carcinoma (5.79% in group C), and cerebrovascular Deformity (accounting for 71.6% of the D group). The four groups of patients had different characteristics in terms of age and sex. Group B was the oldest with an average age of 42.62 years. The ratio of metastases to intracranial and spinal canal was 1.5: 1, accounting for 3% of all cases. 5% (117 cases) and 2.3% (78 cases).  Conclusion Changsha area of ​​CNS tumor lesions and foreign countries compared to no significant regional differences, and domestic coverage of the data there are different degrees of similarity
