Morbidity, Mortality, and Reliability of Accounting of Patients of Different Age Groups with Liver Cancer in Russia

Abstract

Liver cancer is a severe oncopathology. Mortality exceeds the number of primary-accounted patients in Russia on average. Every year in Russia more than eight thousand (8 810 in 2018) cases of liver cancer and more than 10 000 (10 018 in 2018) deaths from this cause are registered. Used Standard methods of medical statistics, all registered primary cases of liver cancer in Russia. In-depth development of the material was carried out on the basis of the database of the Population cancer register of the North-Western Federal district of the Russian Federation. The analysis of the data of the whole complex of available information in Russia as a whole is carried out. In-depth data development was carried out on the basis of the database of the Population cancer register of the North-Western Federal district of the Russian Federation. The increase in the incidence of liver cancer in Russia over 18 years in «rough» indicators and absolute numbers by 20% and in standardized by 1,22% was established. In women, there was a decrease in reported cases of liver cancer by 4,55%. The mortality rate of the Russian population in standardized indicators has decreased by almost 3% over 18 years. The excess of the number of deaths over those from liver cancer increases significantly in older age groups. The index of reliability of accounting is the ratio of absolute numbers or «rough» indicators of mortality to morbidity. For all malignant tumors, its value on average in Russia was 0,47, almost coinciding with the average European. The index of reliability of accounting for men is 0,55, higher than the calculated indicators for women - 0,40, which is primarily due to a more favorable structure of the incidence of malignant tumors in women. The median survival of primary liver cancer patients is a little more than three months. The five-year survival rate of patients with liver cancer even in the early stages is in the first among persons younger than 60 years - 25,3%, over 60 years - only 17,2%, in the second, respectively, 17,9 and 11%.
