Time series studies, Colorectal neoplasms, Demographic data, Regression analysis


Objective: To analyze the temporal trend of incidence of colorectal cancer (CRC), according to sex and age, in Greater Cuiabá, Mato Grosso, Brazil, from 2000 to 2016. Methods: Ecological time series study, with cases of CRC (C18 to C21) diagnosed from 2000 to 2016, of residents of Greater Cuiabá (Cuiabá and Várzea Grande), in Mato Grosso. Information on the cases was obtained from the Population-Based Cancer Registry and population data from IBGE. Rates were adjusted by world population. The age groups from 30 to 39 years old, 40 to 49 years old, 50 to 59 years old, 60 to 69 years old, 70 to 79 years old and 80 years old or more were considered. To analyze the trend of incidence, the Joinpoint regression was used. Results: A total of 1,715 cases of CCR were registered with information on sex and age, with an adjusted rate of 16.4 new cases/100,000 men and 16.1 new cases/100,000 women. Men presented trend of increasing incidence rates in the age group of 70 to 79 years, with increase of 4.0% per year, while women presented trend of increase in the age group 50 to 59 years, with increase of 2.7% per year. Conclusion: Older men showed more significant trend towards an increase in the incidence of CRC, but in women this occurred in a younger age group, highlighting the importance of considering information about age in the analyzes of the occurrence of the disease in this population.
