Insights
This study found lower incidence and survival rates for pediatric soft-tissue sarcomas (STSs) and malignant bone tumors (MBTs) in Iran compared to high-income countries. Improving cancer registries is crucial for better sarcoma prevention and control.
Area of Science:
- Pediatric oncology
- Cancer epidemiology
- Sarcoma research
Background:
- Pediatric sarcomas encompass soft-tissue sarcomas (STSs) and malignant bone tumors (MBTs).
- Understanding the epidemiology of these rare cancers is vital for public health initiatives.
Purpose of the Study:
- To determine the incidence and survival rates of pediatric STSs and MBTs in Iran.
- To analyze these rates based on diagnosis date, gender, age, and histological types.
- To compare Iranian data with international benchmarks.
Main Methods:
- Utilized data from the Iran National Cancer Registry (2008-2015).
- Classified cases according to the International Classification of Childhood Cancer (3rd ed.).
- Calculated age-standardized incidence rates (ASIRs) and five-year survival rates for available data.
Main Results:
- Survival data was available for only 21% of pediatric sarcoma cases.
- Incidence and survival rates for MBTs and STSs in Iran were lower than in high-income countries.
- Survival rates for these malignancies were significantly lower in Iran compared to high-income nations.
Conclusions:
- This is the first comprehensive study on pediatric sarcomas in Iran.
- The findings highlight disparities in incidence and survival rates compared to high-income countries.
- There is an urgent need to enhance the quality and quantity of Iran's population-based cancer registries for improved sarcoma management.
Background:
Pediatric sarcomas are divided into two major groups of soft-tissue sarcomas (STSs) and malignant bone tumors (MBTs).
Aims:
The aim of the present study was to determine the incidence and survival rate of STSs and MBTs in the Iranian population based on diagnosis date, gender, age, and histological types.
Methods And Results:
Data was retrieved from Iran National Cancer Registry between 2008 and 2015. The dataset was classified according to the third edition of the International Classification of Childhood Cancer. The survival information was merely available for 291 (21% of total data), including 142 (49%) MBTs and 149 (51%) STSs. The age-standardized incidence rates (ASIRs) and five-year survival rates were calculated.
Conclusion:
The present study is the first comprehensive study of pediatric sarcomas in Iran, in which a lower incidence and survival rate of MBTs and STSs compared with high-income countries were found. However, the survival rates of these malignancies were higher in high-income countries compared to Iran. This study showed the need to improve the quantity and quality of the population-based registry in Iran for acquiring progress in the prevention and control of sarcomas.
