Abstract

The study of the role of environmental factors in the occurrence of human neoplasms is an important task of medical ecology. An indicator of carcinogenic environmental impacts is childhood tumors due to the predominantly prenatal genesis of tumors at this age. In the structure of childhood oncological morbidity, hemoblastosis predominate. The link between the incidence of childhood leukemia and exposure to ultraviolet radiation, the protective role of sun exposure in relation to the risk of non-Hodgkin’s lymphomas (NHL) and the absence of such in Hodgkin’s lymphoma in children have been established. There is evidence of the connection between childhood hemoblastosis and smoke of various origins. The aim of the study was to evaluate the link between solar activity and smoke with hemoblastosis in the Russian children. We used official data on the incidence of childhood hemoblastosis in Russia in 1997-2020 and data on solar activity from the site of the Royal Observatory of Belgium. The generated dynamic series was subjected to correlation and regression analysis in 11 consecutive iterations with a time delay (lag) from 0 to 10 years in relation to the year of registration of neoplasms. An increase in the incidence of leukemia and a decrease in the incidence of Hodgkin’s lymphoma in the children’s population of Russia have been established. The incidence of NHL in children did not reveal a significant trend. A general pattern was revealed in the form of the connection between childhood leukemia and lymphomas and solar activity, most pronounced in 1997-2008. The increase in the childhood leukemia incidence, taking into account the literature data of the role of exhaust gases in its genesis, can be associated with a threefold increase in the number of cars in Russia during the study period. The reasons for the decrease in the incidence of Hodgkin’s lymphoma require further study. To reduce the risk of hemoblastosis in children, it is advisable to introduce food products into the diet to stimulate autophagy, and transfer factor.
