The purpose was to provide a descriptive epidemiological assessment of the incidence of cancer of the larynxin Kazakhstan and spatial evaluation with gender characteristics. Thgis retrospective study covered all new casesof laryngeal cancer in 11 years (1999-2009). The total number was 4,967 cases, 4,535 (91.3%) in males and 432(8.7%) in women, with a ratio of 10.5:1. The higher incidence in men compared to women was evident in all agegroups, the differences being statistically significant (p<0.05). At the same time revealed a unimodal growth withage, peaking at 70 years and older both sexes. In the dynamics, incidence rates of laryngeal cancer demonstrateda tendency to decrease, in women (T=−6.7%) this being more pronounced than in men (T=−3.3%). Levels weredetermined to produce cartograms of cancer of the larynx for male and female populations, clear geographicalvariation being evidenced. The data are discussed with reference to possible risk factors.
