EVOLUTION OF MORTALITY FOR COLORECTAL CANCER IN BRAZIL AND REGIONS, BY SEX, 1996-2015.

Background: 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.
