The dynamics of the incidence of breast cancer in the Moscow region (2011–2018)

Introduction. Breast cancer is a serious medical and social challenge and the statistics around the world look daunting.Relevance. The incidence of breast cancer is increasing in most countries and this may be due to a number of reasons. First of all, it should be noted the improvement of diagnostic methods, in particular, mass mammographic screening, which allows detecting neoplasms at early stages, before the onset of clinical symptoms. As for mortality rates, in recent years, world statistics show a downward trend in rates.Goal. To analyze the incidence and mortality rates of breast cancer (BC) in the Moscow Region (MO) for the period from 2011 to 2018. The study of indicators in one of the regions of Russia – MO – is of great importance for determining and predicting the true needs of the population in specialized medical care.The purpose of the study was to analyze the incidence of breast cancer (breast cancer) in the Moscow Region (MO) for a period of time from 2011 to 2018.Materials and methods. Some data of the territorial cancer registry of the Ministry of Defense of the Russian Federation on the diagnosis and treatment of patients with breast cancer were used, which will make it possible to determine the needs of this cohort of patients in specialized care.Results. From 2011 to 2018, 26755 new cases of breast cancer were diagnosed in the Moscow Region. The analysis of the comparative stratification in breast cancer in the medical district made it possible to obtain statistically significant differences indicating an increase in the incidence in the period from 2015–2018 in comparison with the period of 2011–2014. The presented data also indicate a trend towards a decrease in the one-year mortality rate over 8 years: from 6.33% in 2011 to 5.32% in 2018. For the period from 2011 to 2018 (8 years) there is an increase in the number of patients with breast cancer who have been in the medical center under dispensary supervision for 5 years or more.Conclusions. Analysis of the data obtained on the indicators of morbidity and mortality from malignant neoplasms is of great importance for determining the needs of the population in specialized medical care.
