The aim of this study was to analyze cancer mortality in Rio Grande do Sul (RS), Brazil, during the period from1979 to 1995. Study variables were sex, age, year and underlying cause of death. The simple linear regression technique was used to evaluate the trend of standardized death rates (direct method, using the population of RS in 1996 as the standard). The most frequent sites of tumors in males were lung, esophagus, prostate, stomach and colon/rectum; in females they were breast, cervix of the uterus, lung, colon/rectum and stomach. Standardized death rates presented a stable trend for all malignant neoplasms in both sexes, as did cancer of cervix of the uterus/ non-specified uterus and colon/rectum tumors in females. A significant rising trend was observed in mortality rates due to lung cancer in both sexes, breast cancer in females, prostate and colon/rectum cancer in males. The rates of stomach cancer presented a significant decreasing trend in both sexes as did esophagus cancer rates in men.
