Evolution of mortality for colorectal cancer in Brazil and regions, by sex, 1996-2015
2018
Colorectal cancer is among the three most frequent neoplasms in Brazil, being a public health problem. Objective – To describe distribution pattern of colorectal cancer mortality in Brazil and regions, according to sex, between 1996 and 2015. Methods – Values of standardized and stratified mortality rates by sex between 1996 and 2015 were used, through polynomial regression models and joinpoint analysis. Results – It was observed that, for linear trends in mortality rates, for both sexes, there is a statistically significant trend increasing in both models, with rates and trends, and higher for men than for women, respectively, 7.3% per year (R2 =0.95, P<0.001) and 6.5% per year (R2 =0.87, P<0.001). It is observed a difference in magnitude and behavior of trend between the regions. Conclusion – It is understood that it is important to know the trend of rates in order to define priority populations for early interventions that increase survival and reduce mortality
