Tumors of the nervous system: Incidence and population selectivity

摘要: Abstract The frequency and population selectivity of primary tumors the nervous system was determined for entire Israel. A national tumor registry in Ministry Health included information on patients discharged from all hospitals country as well data autopsies death certificates. During 5-yr period 1961–1965, 1,354 cases were identified. average annual incidence 12.8 per 100,000 population. Histological verification available 69 cent this study. Glioma most commonly verified (27 cent) and, decreasing frequency, meningioma (17 cent), neurofibroma (12 pituitary adenoma (5 neuroblastoma (3 hemangioma (2 craniopharyngioma (1per dermoid (1 cent). distribution by type within calculated: 3 out 4 involved brain these, 50 cerebrum. Seven occurred spinal cord 12 affected peripheral nerves. Most more common males, with exception which showed a female preponderance. When ethnic groups Israel compared regards tumors, African born immigrants had lowest (7.3 population) European highest (15.6 population). Asian countries an intermediate rate closer to African, whereas Israeliborn rates Europeans. differences among could not be attributed unusual predilection at given site system.
