Introduction. Among neoplasms in children, tumors ofthe central nervous system (CNS) represent the second largest disease group, after leukemia, accounting for around 20% ofcases. These tumors appear with the annual incidence of 20-30/1 permillion (mln). Aim ofthework. Evaluating incidence of childhood CNS tumors in Lublin region. Material and methods. The analysis was conducted between 1988-2000 in Lublin region among children aged 0-17'years. Annual incidences (per 1 mln) were estimatedfor all children, boys and girls, both living in urban andrural regions and for 0-4, 5-9, 10-14, 15-17 years groups. Re-sults. 184 cases ofCNS tumors were reported (48.9% ofthem were boys). It constituted 19.5% ofall neoplastic diseases in children ofthis region. The majority of the patients livedin town areas (54.3%). The incidence was 22.5 per 1 mln. The incidence in boys was stable while in girls it varied significantly during the years of observation. The incidence was higher in town patients than in village ones (25.7 vs. 19.0 per mln). The mean morbidity was lower in male than infemale children (21.5 vs. 23.6per 1 mln). The highest morbidity was noted in children aged 5-9 years (28.1 per 1 mln) andalso 10-14 years (26.4per 1 mln). Conclusions.
