Trends of Colorectal Cancer Incidence, Prevalence and Mortality in Worldwide From 1990 to 2017


Background: Colorectal cancer is a major health problem both in developing and developed countries. This cancer is among the top three commonly diagnosed cancers in males and females. In this context, assessing the Incidence, Prevalence and Mortality Rate trend of this cancer is of great importance.

Methods: We used the data from the GBD 2017 study to assess the global trend of 3 important indicators of colorectal cancer burden and to examine the relationship between trends of these indicators with Human Development Index (HDI). We used the multivariate mixed effects modeling framework with time and HDI as the covariates.

Results: Trend analysis of colorectal cancer burden indicators showed a rather steady trend for mortality rate, while it revealed increasing slopes for both the incidence and prevalence rates. In addition, our findings showed a direct relationship between prevalence and incidence rates of this cancer and HDI level and indirect association between mortality rate and level of HDI.

Conclusion: There were significant changes in indicators of colorectal cancer during the study period. The inverse relationship between mortality due to this cancer and socio-economic status of the countries indicated an urgent need for screening the patients and promoting the level of care in countries with lower levels of HDI.
