“…The mean ages at diagnosis differ in the reported series, presumably because of the very different upper age limits for childhood, the upper limit varying between 12 and 20 years (Matson, 1969;Koos and Miller, 1971;Till, 1975;Yates and Becker, 1976;Dohrman et al, 1976a, b;Heshmat et al, 1976;Schoenberg et al, 1976). The few studies using the usual paediatric upper limit for childhood of 15 years of age also show varying age rates of incidence.…”

Summary.-The total number of children under 15 years of age with intracranial tumours in Denmark during the years 1935-1959 was found to be 533. The average incidence was 21 new cases/106 children/year during the 25-year period in question, and 25/106 children/year during the first 17 years of Danish cancer registration. The sex ratio (290 boys to 243 girls) was not significantly different from that of the child population in Denmark. In 219 cases the tumour was located in the supratentorial and in 314 in the infratentorial space. 9300 of the tumours were histologically verified, with the following order of frequency for the most usual types: astrocytomas (all grades), medulloblastomas, ependymomas, and craniopharyngiomas. Follow-up was 1000%. For the 345 children who survived for more than one month after operation or diagnosis, 36% were alive after 15 years. 119 patients were alive in April 1974 and these were all observed between 15-40 years after diagnosis and operation. Of these 44 had tumours in the supratentorial and 75 in the infratentorial space. 660/" of the survivors with supratentorial and 9000 with infratentorial tumours led a normal life.Most of the survivors had had a cerebellar astrocytoma, a supratentorial astrocytoma, an apendymoma or oligodendroglioma, but other histological diagnoses were also represented, especially in the supratentorial group. The long-term prognosis was especially bad for children with brain-stem tumours, infratentorial ependymomas and medulloblastomas.

“…Incidence rates for all CNS tumors, gliomas, and nerve sheath tumors were higher for whites than blacks in Los Angeles, although the meningioma rates were higher in blacks (Preston-Martin, 1989). An earlier report from the Washington, D.C., metropolitan area disclosed higher proportions of meningiomas and pituitary tumors in blacks compared with whites (Heshmat et al, 1976). In the current study, no racial differences were observed in incidence rates for either meningiomas or pituitary tumors.…”

The Central Brain Tumor Registry of the United States (CBTRUS) obtained 5 years of incidence data (1990-1994)-including reports on all primary brain and CNS tumors-from 11 collaborating state cancer registries. Data were available for 20,765 tumors located in the brain, meninges, and other CNS sites, including the pituitary and pineal glands. The average annual incidence was estimated at 11.5 cases per 100,000 person-years. The higher incidence of tumors in male patients (12.1 per 100,000 person-years) than in female patients (11.0 per 100,000 person-years) was statistically signi cant (P<0.05); the higher incidence in whites (11.6 per 100,000 person-years) compared with blacks (7.8 per 100,000 person-years) was statistically signi cant (P<0.05). The most frequently reported histologies were meningiomas (24.0%) and glioblastomas (22.6%). Higher rates for glioblastomas, anaplastic astrocytomas, oligodendrogliomas, anaplastic oligodendrogliomas, ependymomas, mixed gliomas, astrocytomas not otherwise speci ed, medulloblastomas, lymphomas, and germ cell tumors in male than in female patients were statistically signi cant (P<0.05), with relative risks (RR) ranging from 1.3 to 3.4. Meningiomas were the only tumors with a signi cant excess in females (RR=0.5). We noted higher occurrence rates in whites than in blacks for the following histologies: diffuse astrocytomas, anaplastic astrocytomas, glioblastomas, oligodendrogliomas, ependymomas, mixed gliomas, astrocytomas NOS, medulloblastomas, nerve sheath tumors, hemangioblastomas, and germ cell tumors, with RRs ranging from 1.5 to 3.4. Racial differences in occurrence rates were not observed for predominately benign meningiomas or pituitary tumors. This study represents the largest compilation of data on primary brain and CNS tumors in the United States. Standard reporting de nitions and practices must be universally adopted to improve the quality and use of cancer registry data.

Based on retrospective analysis of 212 cases diagnosed and treated at the King Khalid University Hospital in Riyadh over a period of 5 years, this study is the first attempt to provide preliminary data on intracranial space-occupying lesions in Saudi Arabia. There were 184 (87%) neoplasms and 28 (13%) nonneoplastic tumors, mostly inflammatory masses. Age and sex distribution was comparable with that reported from other studies. Neuroepithelial tumors comprised 39.7% of all intracranial neoplasms, followed by meningiomas (22.8%), pituitary adenomas (16.8%), metastatic tumors (8.2%), malformative tumors (4.3%), and neurinomas (3.8%). Males were generally more affected than females. Tuberculomas constituted about 5% of all intracranial space-occupying lesions and, therefore, should always be considered in the differential diagnosis.
