| dc.description.abstract | Introduction The aim of this study is to evaluate demographics, clinical data, and survival rates of children with cancer over 22 years, and to compare the outcomes, before and after a national health reform was performed. Material and Methods Files of patients, aged 0-19 years, diagnosed with cancer at the Istanbul University Oncology Institute during 1990-2012 were evaluated retrospectively. Results The mean age at diagnosis of 2413 patients was 7.5 +/- 5.1 years (range 3 days to 19 years). Male/female ratio was 1.26. After 2002, the number of patients diagnosed at a localized/low-risk stage compared to advanced stage significantly increased (60.7% vs 65.1%,P = .03). Comparing the period before 2002 to after 2002, a lower percentage of patients were diagnosed with advanced stage non-Hodgkin lymphoma (62.1% vs 45.1%,P = .03), retinoblastoma (9.5% vs 1.4%,P = .005), soft tissue sarcomas (52.1% vs 38.3%,P = .01), neuroblastoma (82.4% vs 56.2%,P = .005), and carcinomas (72.9% vs 65.4%,P = .04) after 2002. The 5-year survival rate of all patients during the entire period was 74.4%. The survival rate significantly increased for non-Hodgkin lymphoma (63.7% vs 91.8%,P < .0001), neuroblastoma (46.8% vs 70.5%,P = .025), and renal tumors (70% vs 92.3%,P = .013) after 2002. Conclusions The increase in patients diagnosed at a localized/low-risk stage and the increase in survival of some types of cancer over years is promising. The national health care reform, enabling patients to easily access free health services, increased awareness, improvement in oncological treatment, and supportive care may have contributed to the progress achieved, and may be a model for other developing countries. | |
