Abstract: Objective The aim of this study was to understand the trends of incidence and mortality of colorectal cancer in Gansu cancer registry areas from 2009 to 2015,and to provide the opinions and suggestions for prevention and treatment strategies of colorectal cancer.Methods The data of colorectal cancer(ICD-10 code for C18-20)were collected from 11 cancer registries in Gansu province from 2009 to 2015.The incidence(mortality),the Chinese standard incidence(mortality),the World standard incidence(mortality),the age-specific incidence(mortality),and the cumulative rate stratified by age,gender and years were analyzed.The Joinpoint Regression program 4.7.0.0 was used to calculate the annual percentage change(APC).Results There were 6 903 new cases of colorectal cancer diagnosed from 2009 to 2015 in Gansu cancer registry areas.The crude incidence was 18.24/100 000,the Chinese standard incidence was 16.51/100 000,and the World standard incidence was 18.97/100 000.There were 1 940 deaths of colorectal cancer reported from 2009 to 2015.The crude mortality was 11.12/100 000,the Chinese standard mortality was 9.57/100 000,and the World standard mortality was 11.81/100 000.Males had higher incidence and mortality of colorectal cancer(20.49/100 000 and 12.50/100 000)than those of females(15.87/100 000 and 9.68/100 000).The incidence and mortality in urban areas were higher those of that in rural areas.The overall incidence and mortality of colorectal cancer in Gansu province from 2009 to 2015 showed a decreased trend(APC=-8.9,t=-3.0,P＜0.05;APC=-0.9,t=-0.3,P=0.8).The incidence trend was statistically significant,and no significant mortality trend have been observed.Conclusion The incidence and mortality of colorectal cancer in Gansu province are relatively high.The assessment of high-risk population for colorectal cancer should be increased,and early screening should be implemented to reduce the incidence and mortality of colorectal cancer.
