Abstract
Leukemia contributes 2.3% to the overall cancer incidence in Serbia and 2.9% in the total mortality, while the estimated incidence and mortality rate for males and females were 8.7 and 6.3 ‰, respectively and occupies 13th place among both sexes in Central Serbia. The objective of our study was to examine the time trends of leukemia in Central Serbia, with a focus on Nisava district, from 1999-2014, using a Joinpoint regression analysis and compare them with the trend in other populations, and identify possible changes. The standardised incidence and mortality were obtained from the Serbian Cancer Registry of Central Serbia. Time trends for incidence and mortality of leukemia were assessed using the annual percent change, estimated through Joinpoint regression analysis (age period cohort models - APC) using the Joinpoint Regression Software. Our results demonstrate a stable trend of the age-adjusted leukemia incidence rate both in males and females in Central Serbia during the observed 1999-2014 period. However, statistically significant decreasing trend of leukemia incidence rate was found in men from Nisava district, while non-significant slightly increasing pattern was present in women. Joinpoint analysis in our research demonstrated favorable mortality declines until the 2002, and than stabile trend in Central Serbia in both sexes to the end of the observed period. Conversely, mortality among males in Nisava district shows a positive trend, but not statistically significant. The results of the study suggest that leukemia profile in Central Serbia was stabile during the study period. It is particularly interesting that incidence is decreasing among male population from Nisava district.

Summary
According to the International Agency for Research on Cancer (GLOBOCAN 2012), leukemia contributes 2.3% to the overall cancer incidence in Serbia and 2.9% in the total mortality, while estimated incidence and mortality rate for males and females were 8.7 and 6.3 ‰, respectively [1]. Among all cancers in Serbia, leukemia occupies 13th place among both sexes. This evidence is based on research conducted at Los Alamos National Laboratory, studies of nuclear workers at other sites, and others exposed to ionising radiation [2, 3]. Previous cancer treatment regimens with known cytotoxic agents that have leukemogenic potential, other factors, such as the intensity of treatment and use of growth factors, may have played a role in leukemia occurrence [6]. Other factors as genetic disorders [9] and socio economic status [10, 11] are confirmed as risk factors for leukemia incidence. Encouraging news in recent decades is that a significant improvement has been set up in the diagnosis and treatment of leukemia
