Brain tumors are rare, but their incidence and mortality have increased in different countries, including Brazil, especially among the elderly. This paper presents the mortality pattern of brain tumors in Brazil, including distribution of mortality rates by gender, age, topography, and tumor staging, from 1980 to 1998. Age-adjusted (by world population) brain cancer mortality rates increased from 2.24/100,000 to 3.35/100,000 inhabitants among the overall population during this period (an increase of 50%). Observed rates were higher during childhood than adolescence and increased with age, reaching the highest levels among the elderly. Among individuals 70 years of age and older, an average annual increase of 6% was observed in the series. Brain and meningeal tumor rates are presented for the entire country and selected State capitals. Further study is needed to elucidate the role of both new diagnostic technologies and environmental exposures potentially associated with the observed changes in brain cancer mortality rates.
