The global, regional, and national burden of colorectal cancer in 204 countries and territories from 1990 to 2019

BackgroundWe aimed to estimate the global burden of colorectal cancer (CRC) between 1990 and 2019.MethodsData were extracted from the Global Burden of Disease study 2019. Estimated annual percentage changes (EAPCs) were calculated to quantify temporal trends in the age-standardized rates of CRC incidence, deaths, and disability-adjusted life-years (DALYs) by age, sex, region, and country. The correlations of EAPCs in the age-standardized rates with sociodemographic index (SDI) were also analyzed.ResultsFrom 1990 to 2019, the CRC incidence, deaths, and DALYs increased worldwide by 157%, 110%, and 96%, respectively. The global age-standardized incidence rate increased (EAPC, 0.58; 95% confidence interval [CI], 0.51-0.66), whereas both the age-standardized death rate (EAPC, -0.21; 95% CI, -0.28 to -0.14) and age-standardized DALY rate (EAPC, -0.21; 95% CI, -0.26 to -0.15) presented downward trends. As for regions, the largest increases in the age-standardized incidence rate, age-standardized death rate, and age-standardized DALY rate were observed in East Asia. In terms of countries, the largest increase in CRC incidence was found in Equatorial Guinea (3.98), followed by Vietnam (3.79) and China (3.66). The age-standardized incidence rate was higher in men than in women. Negative correlations were found between the EAPC in the age-standardized incidence rate of CRC and the SDI.ConclusionsFuture CRC preventive strategies should focus on the male population and older adults, especially in East Asia, Qatar, United Arab Emirates, Saudi Arabia, and other high-risk regions.
