Incidence of Primary Central Nervous System Tumors among Children in Belgrade (SERBIA), 1991-2004

Abstract

The aim of this survey was to estimate the incidence of primary CNS tumors among children aged 0-14 in Belgrade during the period 1991-2004. Incidence rates were age-adjusted according to the world standard population. The average age-adjusted incidence rates were 3.4/100,000 for boys, 2.4/100,000 for girls, and 2.9/100,000 for both genders. There was a nonsignificant tendency toward increased CNS tumor incidence (y = 2.547 + 0.052x, p =.549). The age-specific incidence rates were 3.0/100,000 (0-4 years), 2.2/100,000 (5-9 years), and 3.8/100,000 (10-14 years). Among the population aged between 0 and 14, the cumulative probability of acquiring primary CNS tumors was 1 per 1961 for boys and 1 per 2778 for girls. Astrocytoma was the most common pathohistological type of primary CNS tumors accounting for 41.5% of cases. © Informa Healthcare USA, Inc.
