The State of Oncology Care in Russia: Localization Structure Features, Quality of Recording, and Survival of Cancer Patients in the Major Age Groups of the Population (population study). Part 6

Abstract

Malignant neoplasms are considered among the most serious and prevalent diseases in many countries worldwide. In the course of our research, we conducted a review where we synthesized findings from five scientific articles providing detailed descriptions of age-related patterns of prevalence, structure, and survival among oncology patients. The final population-based study presents a culmination of all identified characteristics of this process, particularly regarding the role of age in the characteristics of prevalence and survival of cancer patients, which holds significant importance. The study utilized data from the International Agency for Research on Cancer (IARC), handbooks from the P. A. Herzen MNIOI and the N. N. Petrov National Medical Research Center of Oncology, as well as data from population-based cancer registries databases from the Saint Petersburg and Northwestern Federal District of Russia. Data processing was conducted using licensed software MS Excel 2013–2016 and STATISTICA 6.1. Modified Eurocare software, alongside mathematical, bibliographic, and statistical methods, was employed for survival calculations. The population-based study allowed for a detailed examination of the dynamics of age-specific indicators of morbidity, mortality, quality of initial patient management for MN, and survival rates of MN patients, consolidating vast datasets from across Russia and the Northwestern Federal District of Russia. All gathered and analyzed data indicate an enhancement in the quality of initial patient management for MN, a reduction in mortality rates, and an increase in survival rates.
