Tendência da mortalidade por Câncer de Esôfago em diferentes regiões do Brasil

Abstract

Esophageal cancer (EC) is one of the most lethal malignancies in the world. In this context, this dissertation presents two studies involving this important public health problem. The first study aimed to describe the trend of the mortality rate from EC in the north of the State of Minas Gerais, in the State of Minas Gerais, in the macrorregion southeast and in the Brazil. An ecological time-series study was carried out whose data on deaths and population were obtained from the Information System on Mortality (SIM – DATASUS) and from the Brazilian Institute of Geography and Statistics (IBGE), respectively. A simple linear regression was used for the temporal trend analysis. Throughout the period under study there was a significant increase in the mortality rate from EC in this macroregion (83.46%) compared to the state of Minas Gerais (27.80%), the Southeast region (7.54%) and Brazil (14,55%). Thus, it is suggested that changes in the local patterns of exposure to risk factors along with improvement in the quality of mortality records due to the disease and especially in health care could contribute to the reduction of these mortality rates in the macroregion.
