The state of cancer care in Russia: pancreas cancer (C25). The survival rate of patients, taking into account the stage, localization and histological structure. Part II (clinical-population study)

Abstract

Pancreas cancer (С25) is a cancer with an unfavorable prognosis, remains one of the most lethal types of cancer, at the national level mortality exceeds morbidity. The analysis of patient survival at the population level on the scale of federal districts is not carried out in Russia with the exception of the North-West Federal District. Considering that the levels of standardized rates of morbidity and mortality from pancreas cancer are close in Russia and NWFD, and the value of index of accuracy practically coincide, the results of the population cancer registry (PCR) of the NWFD RF actually characterize the state of cancer care on average in Russia, with the exception of autonomous districts. The aim of the second stage of the study was to identify the true state of the effectiveness of the oncological service in Russia by calculating a key parameter – evaluating its performance, specifically, calculating the leading parameter – the survival rate of patients, taking into account the stage, localization, histological structure, and the possibility of curing patients The conducted research made it possible to determine the effectiveness of providing specialized oncological care to patients with pancreas cancer at the federal district level. An increase in the one–year observed survival rate for the period from 2000 to 2004 to 2015-2019 was established from 16.0 to 21.8% or by 36.3%, and five–year from 5.1 to 6.0%. The median survival rate did not reach 4 years. A significant difference in the levels of one-year survival of patients in different age groups has been established. Significant defects in the distribution of patients according to the stage of the disease were revealed. The specification of patient survival by detailed localization groups and major histotypes of tumors was studied.
