Демографический анализ онкологической заболеваемости и смертности на основе данных популяционных раковых регистров северо-запада России
Data from a well-functioning regional population-based cancer registry makes it possible to calculate a system of indicators characterizing the level of cancer morbidity and mortality of regional population at a certain period of time. These indicators are similar in their characteristics to those of life-tables and are virtually independent of the population’s age structure. To some extent they are also independent of the past levels of cancer morbidity and mortality. Unfortunately, the scope of analysis of data from Russian regional population-based cancer registries is limited. The completeness of incidence and mortality records also remains unknown. We have conducted an analysis of data from 5 regional population-based cancer registries of the North-West Federal District of Russia for early 2002 to late 2013. This article was designed as a comparative study of two time periods: 2002-2007 and 2008-2013. We have analyzed the changes in incidence and mortality (lethality) from the most common groups of malignant neoplasms. We have analyzed the levels and dynamics of age-standardized incidence and mortality rates alongside tabular indicators such as the total number of incident cases, the total number of deaths, the average age at malignant disease onset, the average life expectancy of those ill with cancer, etc. The main purpose is to demonstrate the effectiveness of the proposed analytical methods and the entire range of possible research capabilities that will become available should open access to data from Russian population-based cancer registries be granted.
