Abstract

e22519 Background: Global actions on pediatric cancer control is targeting to improve the survival rates in low and middle income countries which already exceeded 80% in high income countries. Almost 300.000 pediatric cancer cases annually are expected in children and adolescents aged 0-14 globally. Pediatric cancer registry must be a priority within the pediatric cancer control programs. Here, we present the most updated results of the pediatric cancer registry in Turkey. Methods: Pediatric cancer registry has been established by the Turkish Pediatric Oncology Group and Turkish Pediatric Hematology Association in 2002. The childhood cancer cases registered between 2009-2020 was included in this analysis. International Childhood Cancer Classification System was used for the classification. Essential demographic findings, ICD-O-3 morphology and topography codes were recorded for each case. Results: During the 12 years from 2009 to 2020, 21792 cases were registered. For all cases, median age was 6.7 year (0-19; M/F 12198/9584, 4 hermaphrodite, 6 unknown). Age distribution was 0-4 yrs, 40.9%; 5-9 yrs, 23.7%; 10-14 yrs, 23.4%; 15-19 yrs, 12.0%) The distribution of the tumor types were [number of cases, percentage of total, median age yrs, M/F]: Leukemia (5208, 23.9%, 5.5, 3004/2204); Lymphoma & other RES tumors (4103, 18.8%, 9.8, 2733/1367, 1 hermaphrodite & 2 unknown); CNS [brain & spinal] (3269, 15.0%, 6.8, 1794/1474, 1 unkown); Symphatetic system (1794, 8.2%, 2.4, 933/861); Retinoblastoma (610, 2.8%, 1.4, 339/271); Renal (1079, 5.0%, 3.1, 524/553, 1 hermaphrodite & 1 unknown); Liver (376, 1.7%, 2.2, 216/160); Malignant bone (1448, 6.6%, 12.5, 787/661); Soft tissue sarcomas (1554, 7.1%, 7.6, 888/666); Germ cell (1461, 6.7%, 9.3, 547/910, 2 hermaphrodite, 2 unknown); Carcinoma & other malignant epithelial (745, 3.4%, 13.5, 362/383); Other/non-specific malignant (145, 0.7%, 7.9, 71/74). Five year survival rate was found as 72%. Conclusions: This registry shows the imrovement of survival rates to 72% in Turkey which is comparable with middle income countries. The pediatric cancer control community is investing on the control of childhood cancer for further improvement and this registry became a valuable source for pediatric oncology community at national and international level.
