Background: Each year more than 200,000 new cancer cases are expected in children & adolescents aged 0-14 years at global level. Although the long term survival rates have been improved to 85% in high income countries, it is still lower than this LMICs with a wide range around the world. Pediatric registries are critical for planning for pediatric cancer care. This study summarizes the update of pediatric cancer registry in Turkey. Aim: To analyze the pediatric cancer distribution through Turkish Pediatric Cancer Registry for the years of 2009-2017. Method: Turkish Pediatric Oncology Group and Turkish Pediatric Hematology Association established a Web based cancer registry in Turkey in 2002. The registry information for 2002-2008 was presented earlier. This study, now, is presents the distribution of pediatric cancers for the years of 2009-2017. International Childhood Classification System was used in classification. Basic demographic findings, ICD-O-3 morphology & topography codes were recorded for each cases. This is an update of the Turkish Pediatric Cancer Registry. Results: During the 9 years from 2009 to 2017, 14,769 pediatric cancer cases were recorded. For all cases, median age was 6.7 years (0-17 M/F 8318/6443, 3 hermaphrodite 5 unknown). Age distribution was 0-4 yrs, 40.8%; 5-9 yrs, 24.5%; 10-14 yrs, 23.3%; 15-19 yrs, 11.4%. The distribution of tumor types were [number of cases, percentage of total, median age years, M/F]: leukemia (4114, 27.9%, 5.5, 2366/1748); lymphoma and other RES tumors (2823, 19.1%, 9.6, 1904/914, 1 hermaphrodite 4 unknown); CNS [brain & spinal] (1950, 13.2%, 7.1, 1072/828); sympathetic system (1166, 7.9%, 2.4, 609/557); retinoblastoma (351, 2.4%, 1.4, 197/154); renal (736, 5.0%, 3.3, 345/391); liver (242, 1.6%, 1.8, 132/110); malignant bone (965, 6.5%, 12.6, 527/438); soft tissue sarcomas (991, 6.7%, 7.4, 580/411); germ cell (911, 6.2%, 8.2, 331/577, 2 hermaphrodite, 1 unknown); carcinoma and other malignant epithelial (436, 3.0%, 13.6, 212/224); other/nonspecific malignant (84, 0.6%, 7.1, 43/41) tumors. Five year survival rate was found as 67.8%. Conclusion: Registry provides the essential information for planning the pediatric cancer care. This registry became a critical source for health care professionals in Turkey since beginning. Survival rates for children increased to 67.8% based on this study. This is compatible with the survival rates from other upper middle income countries. This data also allows the comparison of the national data with the national and international studies. Investment on the pediatric cancer registry is one of the first steps of investments on pediatric cancer care.

Purpose To determine predictive strength of tumor cell ploidy and MYCN gene amplification on survival of children older than 12 months with disseminated neuroblastoma (NB). Patients and Methods Of 648 children with stage D NB enrolled onto the Pediatric Oncology Group NB Biology Study 9047 (1990-2000), 560 children were assessable for ploidy and MYCN amplification. Treatment of patients older than 12 months varied; most receiving high-dose chemotherapy with stem-cell rescue. Infants received standard chemotherapy, depending on MYCN status and ploidy. Results Among stage D MYCN-amplified patients, 4-year event-free survival (EFS) ± SE had no prognostic significance for tumor cell ploidy for patients either younger than 12 months or ≥ 12 months old. However, among stage D nonamplified-MYCN patients, 4-year EFS for those with tumor hyperdiploidy (DNA index [DI] > 1) was clearly superior to those with diploidy (DI ≤ 1): younger than 12 months, 83.7% ± 4.4% (n = 87) versus 46.2% ± 13.8% (n = 13; P = .0003); and for 12- to 24-month-old children, 72.7% ± 10.2% (n = 22) versus 26.7% ± 13.2% (n = 16; P = .0092). Further analysis suggested better prognoses in the 12- to 18-month-old subgroup with hyperdiploid tumors (4-year EFS, 92.9% ± 7.2%) compared with the 19- to 24-month-old subgroup (4-year EFS, 37.5% ± 21.0%; P = .0037). In children older than 24 months, outcome was dire (< 20% long-term survival), regardless of ploidy or MYCN status. Conclusion Children 12 to 18 months old with metastatic NB had favorable outcomes with high-dose therapy if their tumors were hyperdiploid and lacked MYCN amplification. This subgroup may respond well to contemporary chemotherapy, and could be spared intensive myeloablative therapy with stem-cell rescue.

PURPOSE Although a high rate of spontaneous regression is observed in infants with stage D(S) neuroblastoma (NB), survival is not uniform. To determine the prognostic relevance of age at diagnosis, therapy, and tumor biology in infants with stage D(S) NB, we reviewed the Pediatric Oncology Group (POG) experience. PATIENTS AND METHODS A review of patients diagnosed with stage D(S) NB registered on POG protocols was performed. Survival according to age at diagnosis, treatment, and tumor biology was determined. RESULTS Between 1987 and 1996, 110 infants with stage D(S) NB had an estimated 3-year survival rate of 85% +/- 4%; survival rate was 71% +/- 8% for infants 2 months of age or younger, and 68% +/- 12%, 44% +/- 33%, and 33% +/- 19% for patients with diploid, MYCN-amplified, and unfavorable histology tumors, respectively. Survival rates were similar for patients who received adjuvant chemotherapy versus those who did not (82% +/- 5% v 93% +/- 6%, respectively; P = .187). Furthermore, there was no statistical difference in survival rate for patients who underwent complete resection of their primary tumor compared with those who underwent partial resection or biopsy only (90% +/- 5% v 78% +/- 7%, respectively; P = .083). CONCLUSION Our review confirmed that the survival of infants with stage D(S) NB is excellent. However, subsets of patients with poor prognosis can be identified by young age and unfavorable biologic factors. More effective therapy is needed for the group of stage D(S) infants who show unfavorable clinical and biologic features.

10067 Background: In childhood cancers cure rates increased up to 80% in the developed countries. On the other hand cure rates goes down 10-20% percent in countries with low resource settings. Reliable pediatric cancer data is essential for all countries. We established a nationwide pediatric cancer registry. Methods: Turkish Pediatric Oncology & Pediatric Hematology Society established a web-based database for the registry of all pediatric cancers. 11898 cases were registered between 2002-2008 from 65 centers. Various demographic data & survival endpoints were recorded & analyzed. Diseases were grouped according to the International Classification of Childhood Cancer. Results: In all 11898 cases, median age was 6 years (M/F= 6786/5112=1.32). Distribution in age groups were: 0-4 years, 42.5%; 5-9 years, 27.2%; 10-14 years, 23.4%; 15-19 years, 6.8%; >19 years, 0.1%. Only 3.8% of cases were diagnosed with clinical+radiological, the rest with histopathological data Distribution of cases in disease groups were [median age in yrs, M/F]: Leukemias (n=3777) 31.7% [5.5, 2137/1640=.31]; Lymphomas (n=2040) 17.1% [8.3, 1405/635=2.21]; CNS tumors (n=1588) 13.3% [6.9, 913/675=1.3 ]; Sympathetic tumors (n=889) 7.5% [2.1, 453/436=1.03]; Retinoblastoma (n=371) 3.1% [2, 181/190=0.95]; Renal tumors (n=655) 5.5% [3, 333/322=1.03]; Hepatic (n=166) 1.4% [1.8, 101/65=1.5]; Bone tumors (n=717) 6% [12.2, 407/310=1.3]; Soft tissue tumors (n=773) 6.5% [6.5, 442/331=1.3]; Germ cell tumors (n=531) 4.5% [5, 210/321=0.6 ]; Carcinomas and other malignant epithelial tumors (n=323) 2.7% [12, 164/159=1.03]; Others/unspecified malignant tumors (n=68) 0.6% [4.5, 40/28=1.4]. Five-year overall survival in all cases was 65%. Conclusions: This registry provides a critical information about the distribution of childhood cancer since this is the only nationwide pediatric cancer registry in Turkey. With the recent trends in non-communicable diseases at global level, registry data will be very helpful for national cancer control plans, which will also be used to compare at national and international level. This will also be a good example for many other countries with similar resources to do such projects.

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.
