The state of cancer care in Russia: cancer of the small intestine (C17). morbidity, mortality, index of accuracy, annual mortality (population study at the federal district level). Part I
Abstract
Relevance. Small intestine cancer is extremely rare cancer among the Russian population with the incidence of less than 1 per 100,000 populations. in 2019, 1,643 cases of small intestine cancer were recorded in Russia, including 750 cases among the male population, and 893 among the female population. only since 2011 state statistics provides for the inclusion of primary cases of small intestine in a separate line in the state report form № 7. in 2019, none of the small intestine cancer cases was registered in four administrative territories of Russia, and only one case was registered in 13territories among the female population. in the North-Western Federal district (NWFD) of the Russian Federation, 187 primary cases of small intestine cancer were diagnosed in 2019; the standardized incidence rates were 0.91 and 0.57 0/0000 for men and women, respectively. more than 1,200 people die from small intestine cancer annually in Russia, and approximately 130 people die from this cancer in the Northwestern Federal district of the Russian Federation. the standardized mortality rates among the population of Russia and the Northwestern Federal district of the Russian Federation for men and women are 54 and 0.58 per 100,000 and 0.33 and 0.37 per 100,000, respectively. The purpose of the study was to analyze small intestine cancer incidence and mortality rates in the population of Russia. Material and methods. The population-based cancer registries of IARC, P.A. Herzen institute of oncology, N.N. Petrov Research institute of oncology as well as the population-based cancer registries of the Northwestern Federal District of the Russian Federation were used. Standard methods of oncology statistics were used. Results. the study, for the first time in Russia, made it possible to estimate the prevalence of small intestine cancer, which is much less common in Russia than in the USA and in other economically developed countries. Conclusion. In females, a significant decrease in standardized mortality rates of small intestine cancer was revealed. in males, this rate remained almost unchanged. a positive dynamics of annual mortality rates, especially within the first year of follow-up, was found.
