Full Effect

To evaluate, by analysis of breast cancer mortality data from all the 26 Swedish counties for the years 1971 to 1990, whether the effect of the introduction of mammography screening in Sweden can be assessed by observation from existing mortality data. A Poisson regression model was used to study whether a decrease in breast cancer mortality among women aged 50–74 years was associated with the extent of mammography screening in different counties and periods. In regions where mammography screening had been introduced, breast cancer mortality tended to be decreased, on average, compared with regions with-'out screening. If a 10 year time lag between the start of screening and its full effect on mortality is assumed then the estimated reduction in breast cancer mortality associated with introduction of screening was 19% with a 95% confidence interval ranging from 3% to 37%. The results suggest that the effect of mammography screening may be studied using existing routine mortality data and appropriate statistical modelling. This way of assessing the outcome of the screening is valuable when continuously monitoring a screening programme that has become a public health routine.

In 2012, the Euroscreen project published a review of incidence-based mortality evaluations of breast cancer screening programmes. In this paper, we update this review to October 2019 and expand its scope from Europe to worldwide. We carried out a systematic review of incidence-based mortality studies of breast cancer screening programmes, and a meta-analysis of the estimated effects of both invitation to screening and attendance at screening, with adjustment for self-selection bias, on incidence-based mortality from breast cancer. We found 27 valid studies. The results of the meta-analysis showed a significant 22% reduction in breast cancer mortality with invitation to screening, with a relative risk of 0.78 (95% CI 0.75–0.82), and a significant 33% reduction with actual attendance at screening (RR 0.67, 95% CI 0.61–0.75). Breast cancer screening in the routine healthcare setting continues to confer a substantial reduction in mortality from breast cancer.

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.
