Abstract

Background: The childhood cancer registry in Iran is a hospital-based system and there is not any unique and national registry system for pediatric malignancies in Iran. According to the limitations and requirements, this study was designed to clarify the aspect of childhood malignancies in Iran and promote establishing the Iranian national childhood cancer registry system.

Materials and Methods: This cross-sectional longitudinal study was implied on 1500 patients younger than 20-years old diagnosed with any malignancy and admitted at MAHAK Pediatric Cancer Treatment and Research Center (MPCTRC) from 2007 to 2014. Data collection was based on a validated questionnaire with three categories including demographic data, clinical data and type of malignancy, and outcomes. Collected data were analyzed using methods for qualitative and quantitative variables (P-Value < 0.05) by SPSS software version 22. The survival rate was calculated by the Kaplan-Meyer method.    

Results: This study was implied on 1500 children with a mean age of 6.1 years old. The most common malignancy was acute leukemia (30.7%) followed by central nervous system tumors (27%). At the onset of starting treatment, the rate of conferring with relapse, metastasis, and secondary malignancies was 29%, 19.5%, and 1% respectively. In addition, 52 patients had bone marrow transplantation of whom, 14 cases died. Totally, 42% of patients died and the 3-years, 5-years, and 10-years overall survival rates were 67.7% ± 0.01, 60.3% ± 0.01, and 53.8% ± 0.01, respectively.

Conclusion: Establishing a population-based pediatric cancer registry in Iran is necessary and will be useful for improving the survival rate of mentioned patients.
