Regional and gender differences in laryngeal cancer mortality: trends and predictions until 2030 in Brazil

ObjectiveAnalysis of laryngeal cancer mortality trends in Brazil and its geographic regions for the period 1996-2010 and calculation of mortality predictions for the period 2011-2030.Study DesignAn epidemiologic, ecologic, demographic-based study, which utilized information from the Mortality Information System on all cancer-related deaths in Brazil, is presented here. Mortality trends were analyzed by Joinpoint regression, and Nordpred was utilized for the calculation of predictions.ResultsWhen comparing the last observed period and the last predicted period for men, an increase of 10,588 deaths is expected, representing an increase of 69%. For women, the expected increase in the number of deaths will be 2217, representing an increase of 104%. Laryngeal cancer mortality rates will increase in the North and Northeast regions for men and in the Northeast and Southeast regions for women.ConclusionsDespite the current high mortality for laryngeal cancer, rates will continue to increase until 2030 in Brazil.
