Abstract:
Background:Although childhood cancer accounts for a small percentage of total cancer cases globally,
it remains a critical public health issue. Studying the incidence of childhood and adolescent
cancer in Ulaanbaatar, where nearly half of Mongolia's population resides, is essential for
improving diagnosis and treatment quality.
Objective:To investigate the patterns and trends of new childhood and adolescent cancer cases in
Ulaanbaatar from 2015 to 2024.
Material and Method:A descriptive cross-sectional study was conducted. Based on statistical data from the
Center for Health Development, incidence rates per 100,000 population were calculated and
analyzed using STATA 14.2 software.
Results:A total of 516 new cases were recorded during the study period, with an average incidence
rate of 9.0 per 100,000 population. The incidence increased by 35.2%, rising from 8.8 in
2015 to 11.9 in 2022. Regarding cancer types, hematological and lymphoid malignancies
dominated (50%). The highest incidence was observed in the 0–4 age group (12.5). The
male-to-female ratio was 1.4, showing a male predominance. By district, the highest overall
incidence rates were observed in Bayangol (10.3 per 100,000), Songinokhairkhan (9.6), and
Bayanzurkh (9.4), while the lowest rates were observed in Nalaikh (4.7) and Bagakhangai
(0.0).
Conclusion:The incidence of childhood cancer in Ulaanbaatar has shown an increasing trend over the
last decade. The patterns of cancer types, age, and sex distribution are consistent with
international and Asian regional trends.
