The Role of Dirofilaria Repens Infection in the Development of Oncological Diseases in Different Regions of World

Abstract

A statistical assessment was made of the data for 2016 on the identified cases of oncological diseases and invasions by helminths of the genus Dirofilaria in population of different regions of the world using the statistical method and correlation analysis according to Spearman. The results of the correlation analysis showed an inverse relations between the invasion level and the number of diagnosed oncological diseases on most continents, except for countries of South America, where the relationship between the two studied pathologies was direct (0.314). However, the values of statistical correlation for South America can be considered as little informative, since the known statistics on infection with dirofilariasis is close to zero. The revealed correlation in other regions (Asia –0.15; Europe –0.486; Africa –0.85) suggests that as the prevalence of Dirofilaria helminths in population increases, fewer cases of oncological diseases are recorded and vice versa. At the same time, it should be considered that this relationship is influenced by many other factors, the main of which we can consider modern medicine. In general, the study of the relationship between Dirofilaria infection and the oncological disease requires further study
