ABSTRACT

Objective@#To understand the characteristics and trends of colorectal cancer incidence and mortality in Lishui residents from 2014 to 2018,so as to provide basis for the development of prevention and treatment measures of colorectal cancer.@*Methods @#The incidence and mortality data of colorectal cancer in Lishui from 2014 to 2018 were collected through the information management system of chronic disease surveillance in Zhejiang Province. The incidence,mortality and annual percentage change(APC)of colorectal cancer were calculated and analyzed in different genders,ages and regions were analyzed. @*Results@#From 2014 to 2018,there were 4 403 new cases of colorectal cancer in Lishui,with the crude and standardized incidence rate of 34.89/100 000 and 20.99/100 000,respectively. There were 2 369 deaths,with a crude mortality rate of 18.77/100 000 and a standardized mortality rate of 10.17 /100 000. The crude incidence rate and crude mortality rate in males were higher than those in females(39.71/100 000 vs. 29.77/100 000,21.31/100 000 vs. 16.08/100 000,both p<0.05). There were no statistically significant differences between urban and rural residents in the crude incidence rate and crude mortality rate(37.24/100 000 vs. 34.44/100 000,19.75/100 000 vs. 18.45/100 000,both p<0.05). The crude incidence rate and crude mortality rate increased with age. The APC of the mortality rate of colorectal cancer among urban residents was 11.31%,showing an increasing trend from 2014 to 2018(p<0.05). @* Conclusion@#The incidence and mortality of colorectal cancer are high in Lishui,and the focus groups are men,people aged over 40 years and urban residents.
