Breast cancer is the most prevalent form of cancer in the world. Breast cancer mortality rates are high in Brazil and show striking variations between geographic regions. A time-trend ecological study was performed in Southern Brazil from 1980 to 2002. Data were collected from the Mortality Information System (Ministry of Health) to assess age-standardized mortality rates. Linear regression for mortality time-trend analysis and multiple regression for mortality differences among three States were calculated. The highest mean mortality rate (14.45) was observed in Rio Grande do Sul, significantly greater (p < 0.001) than in Santa Catarina (8.93) and Paraná (9.95). An annual increase of 0.47 in the mortality rate was observed in the three States of Southern Brazil. According to these results, the South of Brazil and especially the State of Rio Grande do Sul showed a significant upward trend in breast cancer mortality. Continued efforts are needed to help explain these numbers and reverse the present situation.
乳腺癌是全球最常见的癌症形式。巴西的乳腺癌死亡率很高，且不同地理区域之间存在显著差异。1980年至2002年在巴西南部进行了一项时间趋势生态研究。从（卫生部）死亡信息系统收集数据以评估年龄标准化死亡率。计算了死亡率时间趋势分析的线性回归以及三个州之间死亡率差异的多元回归。南里奥格兰德州的平均死亡率最高（14.45），显著高于圣卡塔琳娜州（8.93）和巴拉那州（9.95）（p < 0.001）。在巴西南部的三个州观察到死亡率每年增加0.47。根据这些结果，巴西南部尤其是南里奥格兰德州的乳腺癌死亡率呈显著上升趋势。需要持续努力来解释这些数据并扭转当前局面。
