[Geographical differences in esophageal neoplasm mortality in Rio Grande do Sul].
Mortality data from cancer of esophagus were studied in the 24 microregions of the State of Rio Grande do Sul (RS), Brazil, from 1970 to 1989, in males and females. The mortality data were calculated through information from the Health Department of RS and the population was obtained in IBGE and FEE. The average, the standard deviation and, by linear regression, the angular parameter of the temporal series for the State and each microregion, were calculated. We noticed great differences between the average of death rates in the 24 microregions, with values between 16.49 to 4.74, in males. The microregions of the south of the State, where there are many farms, revealed higher death rates of mortality by esophageal cancer. The tendency showed to be ascending in 54% of the microregions, in the males.
