Incidence and mortality by larynx cancer in Central and South America.

OBJECTIVE: To describe how the incidence and mortality trends for laryngeal cancer in South and Central American countries. METHODS: Time series study, with incidence data from the International Agency for Research on Cancer, from 1990 to 2012 and mortality data from 17 countries of the World Health Organization, from 1995 to 2013. The trend was analyzed by Joinpoint regression. RESULTS: The highest incidence rate for laryngeal cancer was in Brazil, with 5.9 new cases per 100,000 men, and the highest mortality rate in Uruguay with 4.2 deaths per 100,000 men. The incidence ratio between genders ranged from 4: 1 (Colombia) to 12: 1 (Ecuador). The mortality ratio between the sexes ranged from 4: 1 (Peru) to 14: 1 (Uruguay). CONCLUSION: Most countries had low incidence rates and reduced mortality in Latin America.

RESUMEN Objetivo: Describir cómo tendencias de incidencia y mortalidad por cáncer de laringe en países de América del Sur y Central. Métodos: Estudio de series temporales, con datos de incidencia de Agencia Internacional de Investigación sobre el Cáncer, de 1990 a 2012 y datos de mortalidad de 17 países de Organización Mundial de Salud, de 1995 a 2013. La tendencia se analizó mediante regresión de Joinpoint. Resultados: La tasa de incidencia más alta para el cáncer de laringe fue en Brasil, con 5.9 casos nuevos por cada 100,000 hombres, y tasa de mortalidad más alta en Uruguay con 4.2 muertes por cada 100,000 hombres. La razón de incidencia entre géneros varió de 4: 1 (Colombia) a 12: 1 (Ecuador). La razón de mortalidad entre los sexos varió de 4: 1 (Perú) a 14: 1 (Uruguay). Conclusión: La mayoría de países tenían tasas de incidencia bajas y mortalidad reducida en América Latina.

RESUMO Objetivo: Descrever as tendências da incidência e mortalidade para o câncer de laringe em países da América do sul e central. Métodos: Estudo de série temporal, com dados de incidência da Agência Internacional para Pesquisa do Câncer, no período de 1990-2012 e dados de mortalidade de 17 países da Organização Mundial da Saúde, no período de 1995-2013. A tendência foi analisada pela regressão Joinpoint. Resultados: A taxa de incidência mais elevada para o câncer de laringe foi no Brasil, com 5,9 casos novos por 100.000 homens, e a taxa de mortalidade mais elevada foi no Uruguai com 4,2 óbitos por 100.000 homens. A razão de incidência entre os sexos variou de 4:1 (Colômbia) até 12:1 (Equador). A razão de mortalidade entre os sexos variou de 4:1 (Peru) a 14:1 (Uruguai). Conclusão: A maioria dos países apresentou baixas taxas de incidência e redução de mortalidade na América Latina.

Gender and Regional Differences in Lung Cancer Mortality in Brazil.

BACKGROUND AND OBJECTIVE: This was a population-based ecological with data of deaths from the Mortality Information System. The objective of this study was to analyze the temporal trends of mortality induced by bronchi and lung cancer in Brazil and its geographical regions between 2001 and 2015 and secondly to calculate predictions for 2016-2030. MATERIAL AND METHODS: The mortality trends were analyzed by the Joinpoint regression and calculation of predictions was used the Nordpred software. RESULTS: There was a reduction trend in lung cancer mortality among Brazilian men living in South and Southeast regions of Brazil. However, there was an increasing trend in lung cancer mortality among Brazilian women living in Northeast, Southeast, and South regions of Brazil. When comparing the last observed period and the last foreseen period for males, it is expected an increase of 12.86% in the number of deaths, justified mainly by the change in population structure, with a reduction in the risk of death by the disease. For women, the expected increase is 26.22%, justified both by population structure, and the increased risk of deaths from the disease. The higher rates will be observed in the southern region of the country, for both sexes. CONCLUSION: The mortality induced by lung and bronchial cancer in Brazil was unevenly distributed. However lung cancer incidence had a reducing trend, the mortality caused following it was increased among men. For women, the rates are rising, and until 2030, the mortality load will continue to rise for both.
