Abstract: Objective The aim of this study was to analyze the incidence and mortality in cancer registration areas of colorectal cancer in Yunnan Province from 2012 to 2020,as well as the changing trends from 2012 to 2020,in order to provide a scientific basis for formulating prevention and control strategies for colorectal cancer. Methods The data of colorectal cancer incidence and mortality were collected in cancer registration areas of Yunnan Province from January 1,2012 to December 31,2020.The indicators such as incidence,mortality,age-standardized incidence rate by Chinese standard population(ASIRC),age-standardized mortality rate by Chinese standard population(ASMRC),age-standardized incidence rate by World standard population(ASIRW),age-standardized mortality rate by World standard population(ASMRW)and cumulative rate of colorectal cancer were calculated.The annual percentage change(APC)of ASIRW and ASMRW of colorectal cancer from 2012 to 2020 was calculated. Results In 2020,the incidence of colorectal cancer in cancer registration areas of Yunnan Province was 23.19/100,000(26.74/100,000 in males,19.45/100,000 in females,27.33/100,000 in urban and 21.87/100,000 in rural),and ASIRW was 15.25/100,000(18.40/100,000 in males,12.28/100,000 in females,16.23/100,000 in urban and 14.87/100,000 in rural).In 2020,the mortality of colorectal cancer in cancer registration areas of Yunnan Province was 12.55/100,000(14.30/100,000 in males,10.72/100,000 in females,16.70/100,000 in urban and 11.23/100,000 in rural),and ASMRW was 7.89/100,000(9.57/100,000 in males,6.36/100,000 in females,9.34/100,000 in urban and 7.35/100,000 in rural).The age-specific incidence of colorectal cancer increased rapidly after the age of 30,and reached the peak in the 75~79 age group.The age-specific mortality of colorectal cancer increased rapidly after the age of 40,reaching its peak in the 80~84 age group.From 2012 to 2020,ASIRW and ASMRW of colorectal cancer in cancer registration areas of Yunnan Province showed a downward trend(APC=-1.248%,95% CI:-2.404%-0.079%,P=0.040;APC=-2.890%,95% CI:-4.765-0.977%,P=0.009). Conclusion The ASIRW and ASMRW of colorectal cancer showed a downward trend in the cancer registration areas of Yunnan Province from 2012 to 2020.There were differences in colorectal cancer incidence and mortality by gender,region,and age in Yunnan Province.Therefore,it was still necessary to further targeted monitoring and prevention of colorectal cancer were needed.
