TRENDS OF COLORECTAL CANCER MORTALITY IN BRAZIL AND REGIONS ACCORDING TO SEX, 1980-2011

Introduction: Colorectal Cancer is among the four most common cancers in Brazil, being, therefore, a serious public health problem. The study of their tendency helps to understand its magnitude, vulnerability and transcendence.

Objective: The aim of this study is to describe the distribution pattern of mortality from colorectal cancer in Brazil and regions, by gender, in the period between 1980-2011. I

Methods: t was used, for trend analysis, the values of the standardized mortality rates stratified by sex between 1980 and 2011, through polynomial regression models.

Results: It was observed that there are for trends in mortality rates for both sexes, a statistically significant linear trend of increase in both models, with the highest rates and trends for men than for women, respectively , 10.5% year ( R2 = 0.91, p < 0.001 ) and 6.8 % per year ( R2 = 0.83, p < 0.001 ). Still, we observed a difference in the magnitude and trend of behavior between regions, with the Northeast and North systematically higher rates in females, in South and Southeast systematically higher rates for males, and for Brazil and Midwest are no fees higher among women than among men until 1996, when there is a change in this relationship for sex.

Conclusion:  It is understood, therefore, that it is important to know the trend of rates, especially by sex and age group, in order to define priority populations for early interventions that improve survival and reduce mortality.
