Malignant neoplasms of the heart, prevalence, weather mortality, median survival and survival of patients, taking into account the stage of diseases, localization and histological structure of tumors

Malignant cardiac tumors are rare but dangerous tumors with a high mortality rate, not represented at the population level in any statistical collection. The study of its prevalence is possible only using the system of population cancer registries created in the world. Moreover, not at the regional level, only at the level of the federal district or the entire country. In 1993 we created the first in Russia Population-based Cancer Registry. In February 2019, it was possible to combine cancer registries of all 11 administrative territories of the North-West of Russia, with a population of more than 13 million inhabitants and a database of more than 1 million 100 thousand patients. It was only after the creation of the population cancer registry of the Northwestern Federal District that it became possible to study the patterns of prevalence and survival of patients in all tumor localizations, including, among other things, rare malignant cardiac tumors.
