The state of cancer care In Russia: breast cancer among the female population. Year-by-year lethality, median survival, survival of patients with cancer. (Population study at the federal district level)
To get the real state of cancer care, it is necessary to use only reliable data that are available in all administrative territories In Russia - these are databases (DB) of population cancer registers (PСR). The PRR system created In Russia almost completely complies to international requirements, the development of the database gives a real idea of the effectiveness of the anti-cancer measures carried out. Purpose. Based on the database materials created by the PСR at the level of the Northwestern Federal District (NWFD) with a database of more than 1 million 350 thousand observations, including more than 88 000 patients diagnosed with breast cancer. To study the effectiveness of medical care for women with breast cancer, to consider the patterns of death of women under dispensary supervision. To study the nature of the survival rate of sick women, taking into account a number of factors, such as the stage of the disease, to compare the mortality rates of patients in the first year of follow-up with official state reporting data. Materials and methods. The database of the PСR of the Northwestern Federal District, standards data analyzing methodology recommended by the International Association of Cancer Registries (IACR). Results. Analysis of the dynamics of one-year and five-year survival of breast cancer patients showed a significant improvement in indicators, however, they are below the average European level. By 2018, the one-year relative survival rate of women with breast cancer reached 91.7% in the Northwestern Federal District of the Russian Federation, five-year by 2014 69.2%. The median survival rate is in the range of 8-9 years. Conclusions. Thus, the study revealed a continuing increase in the incidence of breast cancer in women, a decrease in mortality, an improvement in one- and five-year relative survival, a higher level of patient registration and the quality of histological conclusions.
