Summary
Lymphosarcoma incidence in Kazakhstan is increasing overall, with higher rates in men and older age groups. Regional variations exist, with some areas showing declining trends.
Area of Science:
- Oncoepidemiology
- Public Health
- Cancer Research
Background:
- Lymphosarcoma represents a significant public health concern globally.
- Understanding regional incidence trends is crucial for targeted interventions.
Purpose of the Study:
- To analyze the epidemiological trends of lymphosarcoma incidence in Kazakhstan.
- To identify geographical and demographic variations in lymphosarcoma rates.
Main Methods:
- Retrospective descriptive study utilizing oncoepidemiological methods.
- Calculation of crude and age-specific incidence rates.
- Joinpoint regression analysis to determine trends (Average Percentage Change - APC).
Main Results:
- 3,987 cases registered; incidence higher in men (50.7%) than women (49.3%).
- Highest incidence in age groups 65-79 years; increasing trend observed in those over 85 (APC=+8.26) and decreasing in those under 30 (APC=-6.17).
- Overall annual standardized incidence rate increased (APC=+1.43), with geographical variability; declining trends noted in five regions, particularly Karaganda and South Kazakhstan.
Conclusions:
- Lymphosarcoma incidence in Kazakhstan shows an increasing trend with significant geographical disparities.
- Higher incidence in men, but a more pronounced rate of increase observed in women.
- High incidence rates are concentrated in the eastern and northern regions of Kazakhstan.
