Colorectal cancer epidemiology: world trends and incidence of colon cancer in the Republic of Uzbekistan in 2012–2017

Abstract

Objective: epidemiological evaluation of global trends in colorectal cancer and assessment of colon cancer incidence in the Republic of Uzbekistan in 2012–2017.Materials and methods. We used GLOBOCAN data to analyze the situation with colorectal cancer worldwide. We also assessed the incidence of colon cancer, trends, and mean age of patients (by years) registered in the Republic of Uzbekistan. This article emphasizes the need for epidemiological studies of colorectal cancer in Uzbekistan.Results. World trends in colorectal cancer incidence and mortality indicate that these parameters vary across different regions and depend on the economic situation. There are also some sex differences: men are more likely to develop colorectal cancer than women (male to female ratio 1.25:1.0). The number of patient died of colorectal cancer is growing; the male to female ratio is 1.22:1.0.Conclusions. Our assessment of epidemiological situation of colon cancer in the Republic of Uzbekistan demonstrated that its incidence tends to increase, which necessitates further research evaluating regional differences and risk factors for colorectal cancer.
