FEATURES OF THE CUMULATIVE INCIDENCE OF LYMPHOMAS IN DIFFERENT REGIONS OF THE CHERKASY REGION

The aim is to compare the cumulative incidence of Hodgkin's lymphoma and non-Hodgkin's lymphomas between conditionally clean and polluted regions of the Cherkasy region in 2001, 2014. Materials and methods. The incidence of Hodgkin's lymphoma and non-Hodgkin's lymphomas in conditionally clean, radioactive, chemical and radioactively and chemically contaminated regions of the Cherkasy region per 100 thousand population according to the All-Ukrainian census conducted in 2001 and published by the State Statistical Service of Ukraine in 2014. Results. According to the results of our study, in 2001, in the chemically contaminated region of the Cherkasy region, there was an increase in the incidence of mainly diffuse large B-cell lymphoma by 3.781 (p = 0.043) times compared to its conditionally clean territory (1.076; 0.022-2.130 versus 4.070; 0.082-8.058 per 100 thousand population, respectively). In the chemically contaminated area in 2014, a 3.314 times (p = 0.035) higher level of cumulative incidence of unspecified lymphomas was also revealed (1.793; 0.358-3.228 versus 5.945; 0.734-11.156 per 100 thousand population, respectively) compared to clean areas of the Cherkasy region. Conclusions. Thus, the results of our study showed that in 2001, living in a chemically contaminated area increased the growth of the cumulative incidence of diffuse B-cell lymphoma, and in 2014 - lymphomas of an unspecified type.
