老年性中枢神经系统肿瘤556例分析

目的探讨老年性中枢神经系统肿瘤的临床特点。方法对天坛医院2002年6月至2005年5月收治的556例老年性中枢神经系统肿瘤进行回顾性分析。结果老年性中枢神经系统肿瘤病例数占同期中枢神经系统肿瘤病例数的9.03%。肿瘤部位:颅内490例,其中幕上388例,幕下90例,幕上下12例;椎管内66例。病理:最常见的肿瘤为脑膜瘤(254例)、垂体瘤(90例)、神经上皮肿瘤(89例)。预后:手术预后良好491例(占88.31%),不良42例(占7.55%),死亡与濒临死亡23例(占4.14%)。结论老年性中枢神经肿瘤发病率呈逐渐升高趋势,幕上肿瘤多于幕下肿瘤,脑膜瘤多见,手术治疗效果满意,年龄不是手术的禁忌。

Analysis of 556 Cases of Central Nervous System Tumors in Elderly

Objective To investigate the clinical characteristics of central nervous system tumors in elderly patients.Methods The 556 cases of elderly patients with intracranial and intraspinal neoplasms from 2002.6 to 2005.5 were retrospectively analyzed.Results Tumors of the central nervous system in the aging patients accounted for 9.03% of the total in our unit during the same period.There were 490 cases of intracranial tumors,among which the supratentorial tumors were 388 cases,infratentorial tumors were 90 and the tumors involving both supratentorial and infratentorial were 12 cases.there were 66 cases of intraspinal neoplasms.Meanwhile the most common tumors in our group were meningioma(254 cases),followed by pituitary adenoma(90 cases) and tumors of neuroepithelial tissue(89 cases).After operation 491(88.31%) cases recovered very well,42(7.55%) cases and 23(4.14%) cases were died or almost dead.Conclusion The prevacence rate of central nervous system tumors in elderly patients appeared a tendency of increasing.The incidence of supratentorial tumors was much higher than that of infratentorial tumors.Meningomas was the most common type.The surgery treatment is optimism for the tumor,the age was not a ban for the operation.
