Hodgkin lymphoma and Non-Hodgkin lymphomas incidence rates in the Republic of Belarus

Abstract

Hodgkin lymphoma and Non-Hodgkin lymphomas are those of the most expected malignant neoplasms, which could be associated with radiation impact. There have been no epidemiological studies, which would describe lymphoma rates in Belarus for the long time after the Chernobyl disaster. Thus the aim of this study was to estimate lymphomas rates in Belarus within 1991-2014. Data of Belorussian Cancer Registry were analyzed by calculation of crude rates (CR), age-specific rates (AsR) and age standardized rates (ASR). Trend analysis was realized by investigation of average annual percentage change (APC). There were found 6,675 cases of Hodgkin lymphoma (С81.0 - С81.9) and 12,404 of Non-Hodgkin lymphomas (С82.0 - С85.9, С96) in Belarus within 1991-2014. CR and ASR of lymphomas are higher in males than females, but the return ASR of Hodgkin lymphoma is higher in females than males. CR and ASR are higher for urban than rural residents. Trend analysis showed the growth of both crude and standardized incidence rates of Non-Hodgkin lymphomas (APC is about 3.4%), but the return APS of Hodgkin lymphoma made up (-0.2%).
