目的:探讨儿童中枢神经系统肿瘤的发病特点。方法:对华山医院1986~1998年儿童中枢神经系统肿瘤766例,进行回顾性分析。结果:本组占同期中枢神经系统肿瘤病例数的6.14%。部位:颅内725例,其中幕上499例,幕下276例,椎管内41例。组织学分类:前三位分别是:星形细胞性肿瘤(19例,占26.0%);颅咽管瘤(115例,占15.0%);髓母细胞瘤(101例,占13.2%)。性别:男孩多见。发病涉及各年龄组,病例数随年龄的增长而增加。结论:儿童中枢神经系统肿瘤位于幕上者多于幕下,颅内肿瘤以星形细胞性肿瘤最常见,男孩比女孩好发,为1.50:1。
Objective: To investigate the incidence of central nervous system tumors in children. Methods: A retrospective analysis was performed on 766 children with CNS tumors in Huashan Hospital from 1986 to 1998. Results: This group accounted for 6.14% of the cases of central nervous system tumors in the same period. Location: Intracranial 725 cases, of which 499 cases on the screen, 276 cases under the screen, 41 cases of spinal canal. Histological classification: the first three were astrocytic tumors (19 cases, accounting for 26.0%); craniopharyngioma (115 cases, 15.0%); medulloblastoma (101 cases, accounting for 13.2%). Gender: boys more common. Incidence involving all age groups, the number of cases increased with age. CONCLUSIONS: Children with CNS tumors are more likely to be on the screen than those under the screen. Astrocytic tumors are most common in intracranial tumors and 1.50: 1 in boys than in girls.
