R.Fogelholm等学者对芬兰中部367例中枢神经系统肿瘤的流行病学进行了调查,其中298例是在1975—1982年作的诊断,其余早在1975年前作的诊断。8.3%的颅内和90%的脊髓内肿瘤是经组织学证实的,其中14%的颅内肿瘤于1975—1982年在尸体解剖时意外发现而诊断的。颅内转移瘤占全部中枢神经系统肿瘤的18%,原发性和转移性颅内肿瘤的年龄和性别标化发病率分别为12.3及3.4/10万人口,脊髓内肿瘤分别为1.3及0.7/10万人口。所有中枢神 R. Fogelholm et al investigated the epidemiology of 367 central nervous system tumors in central Finland, of whom 298 were diagnosed between 1975 and 1982 and the rest were diagnosed as early as 1975. 8.3% of intracranial tumors and 90% of intraspinal tumors were histologically confirmed, of which 14% of intracranial tumors were diagnosed by accident during autopsy from 1975 to 1982. Intracranial metastases account for 18% of all CNS tumors. The age and gender-standardized morbidity of primary and metastatic intracranial tumors were 12.3 and 3.4 / 100 000, respectively. The intraspinal tumors were 1.3 and 0.7 / 100,000 population. All the central gods
