Cancer is currently in the spotlight due to their heavy responsibility as main cause of death in both developed and developing countries. Analysis of the epidemiological situation is required as a support tool for the planning of public health measures for the most vulnerable groups. We analyzed cancer mortality trends in Brazil and geographic regions in the period 1996 to 2010 and calculate mortality predictions for the period 2011 to 2030.This is an epidemiological, demographic-based study that utilized information from the Mortality Information System on all deaths due to cancer in Brazil. Mortality trends were analyzed by the Joinpoint regression, and Nordpred was utilized for the calculation of predictions.Stability was verified for the female (annual percentage change [APC] = 0.4%) and male (APC = 0.5%) sexes. The North and Northeast regions present significant increasing trends for mortality in both sexes. Until 2030, female mortality trends will not present considerable variations, but there will be a decrease in mortality trends for the male sex. There will be increases in mortality rates until 2030 for the North and Northeast regions, whereas reductions will be verified for the remaining geographic regions. This variation will be explained by the demographic structure of regions until 2030.There are pronounced regional and sex differences in cancer mortality in Brazil, and these discrepancies will continue to increase until the year 2030, when the Northeast region will present the highest cancer mortality rates in Brazil.
癌症目前备受关注,因为它在发达国家和发展中国家都是主要死因,责任重大。需要对流行病学情况进行分析,作为为最脆弱群体规划公共卫生措施的支持工具。我们分析了1996年至2010年期间巴西及各地理区域的癌症死亡率趋势,并计算了2011年至2030年期间的死亡率预测。这是一项基于流行病学和人口统计学的研究,利用了巴西死亡信息系统中所有癌症死亡的信息。通过Joinpoint回归分析死亡率趋势,并使用Nordpred计算预测值。女性(年度百分比变化[APC]=0.4%)和男性(APC=0.5%)的死亡率趋势具有稳定性。北部和东北部地区两性的死亡率均呈现显著上升趋势。到2030年,女性死亡率趋势不会有显著变化,但男性死亡率趋势将下降。北部和东北部地区到2030年死亡率将上升,而其他地理区域的死亡率将下降。这种差异将由到2030年各地区的人口结构来解释。巴西癌症死亡率存在明显的地区和性别差异,这些差异将持续增加,直到2030年,届时东北地区将呈现巴西最高的癌症死亡率。
