This study includes 863 new cases. The sex ratio (M/F) was 1.4, and the mean age 7 years (range: 3 months to 14 years 9 months). The neoplasia rate peaked in the group aged 5-9 years (38.6 %). The most common cancers were: lymphomas (44 %), retinoblastoma (11.7 %), renal tumors (10.1 %), leukemias (6.3 %), and soft tissue sarcomas (5, 9 %). Burkitt lymphoma (85.3 %) and nephroblastoma (90.8 %) were the dominant histological type of lymphoma and renal tumors.
