Abstract
Relevance: Kidney cancer is among the most common oncourological malignancies, which incidence is currently growing. Risk factors for kidney cancer include tobacco smoking, overweight, and a history of hypertension and chronic kidney diseases. Kidney cancer is twice more often in men than in women. The purpose was to study the epidemiological trends in Kazakhstan in 2010-2019 years. Results: In the study period, the kidney cancer incidence increased from 5.64 to 6.74, and mortality decreased from 2.65 to 1.96 per 100 000 population. Both unadjusted and standardized incidence was high at the age of 50-69 years in both sexes. The incidence decreased in the age group below 29, was stable at the age of 30-49, was unstable at the age of 50-69, and was growing at 70 years and above. Unadjusted mortality was high at the age of 70 and above. Standardized mortality was high at the age of 50-69. Conclusion: In Kazakhstan, in 2010-2019, there was an increase in kidney cancer incidence against the background of a decrease in mortality from this disease. The most unfavorable in terms of incidence was the age group of 50-69 years in both sexes. The highest absolute mortality was registered at the age of 70 and above, while standardized mortality rates were the highest at 50-69.
