Spatial assessment of breast cancer mortality in Kazakhstan

Abstract

Breast cancer (BC) mortality analysis at the regional level is important not only for assessing the current epidemiological situation, but also contributes to a better understanding of factors that may affect mortality. Aim. The purpose of the study is to assess the spatial deaths from BC in Kazakhstan. Material and methods. Investigation was retrospective between 2009-2018 years. The materials were collected by statistics Committee by the Ministry of National Economy of the Republic of Kazakhstan concerning the deaths from BC (ICD-10-C50). A method of compiling a cartogram based on the determination of the standard deviation (σ) from the mean (x) was applied. Mortality rates calculated per 100,000 female population were used. Results and discussion. A spatial assessment of breast cancer mortality was presented based on the calculation of mortality rates: low up to 12.80/0000; average from 12.8 to 17.30/0000, and high – above 17.30/0000. It was established that the North Kazakhstan (18.20/0000), Akmola (18.90/0000), East Kazakhstan (20.30/0000) and Pavlodar (22.20/0000) regions, as well as the city of Almaty (21.70/0000) relate to regions with high mortality rates. Conclusion. Features of mortality from BC in the republic have been established, while a spatial assessment (cartogram) of mortality indicates regions with different mortality rates. The obtained data are recommended to be used for monitoring and evaluation of anti-cancer measures – BC screening. Keywords: mortality, breast cancer, cartogram, Kazakhstan.
