The state of cancer care in Russia: malignant neoplasms of the skin (C44). Typical mortality, median survival, observed and relative survival, taking into account the stage of the disease. Population-based research at the federal district level

Abstract

In the previous article, we presented an analysis of the prevalence and quality of registration of patients with malignant neoplasms of the skin (C44) in Russia and the North-Western Federal District, showed the quality of accounting and revealed the features of the dynamics of localization and histological structure.

In this report, for the first time in Russia, our attention is focused on the nature of evaluating the effectiveness of anti – cancer measures based on the main criterion-calculating the survival rates of patients with malignant skin neoplasms at the level of the North-Western Federal District, whose level of "rough" and standardized indicators of morbidity and mortality of the population practically does not differ from the average Russian one.

Calculations of all types of survival rates of patients with malignant skin neoplasms (C44) at the federal district level became possible after the organization in February 2019 of a single database (DB) of the cancer registry of the North-Western Federal District, numbering more than 1 million cases of ZNO, including more than 20,000 with malignant melanoma of the skin (2.0%).

The created database allows for in-depth development of the dynamics of the localization and histological structure for any part of the localization structure (lip, ear, trunk, etc. parts of the body), which is not available for conducting on the basis of state reporting forms formed before receiving all the information characterizing the state of the oncological service, not to mention that when analyzing the activities of the oncological service, databases of population cancer registers are not used and calculations of the main criterion for its assessment – the calculation of patient survival.
