Turkish National Pediatric Cancer Registry 2002-2008 (Turkish Pediatric Oncology Group and Turkish Pediatric Hematology Society).

Abstract

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.
