Realisation of mammography screening in Khanty-Mansiysk Autonomous State – Yugra

Objective : to perform a retrospective analysis of the quality of mammography screening in Khanty-Mansiysk State Region – Yugra from its beginning to 2018 inclusive. Materials and methods . During this investigation a throughout analysis of epidemiological indicators (breast cancer mortality and morbidity), quality indicators (coverage of the target population, cancer detection in general and early detection, sensitivity and morbidity) and mammographic screening performance indicators (projected and observed morbidity and mortality) was carried out. Results and conclusions . During this period, 572,348 women were screened, 9.7 % of whom were recommended for further screening. The coverage of the target population for one round was 33 %. Screening test sensitivity for the specified period was 80 %. The observed number of women with newly detected breast cancer cases of stage I in 2018 made 42 % (53 cases) higher in comparison with expected numbers, and in stage T2+ it made 21 % (62 cases) less. The observed number of deaths in 2018 was 23.7 % lower than expected. The above-mentioned demonstrates once again that mammography screening in Khanty-Mansiysk State Region – Yugra has led to the improvement of early diagnosis of breast cancer. This, in turn, leads to a steady decline in breast cancer mortality among women over 40 years of age.
