Abstract: Objective To analyze the prevalence and mortality of thyroid cancer in cancer registration areas of Gansu province from 2009 to 2015.Methods The cases of incidence(mortality),proportion,ASR China and ASR World of thyroid cancer in cancer registration areas of Gansu province from 2009 to 2015 were reviewed and summarized,and the incidence and mortality of thyroid cancer by age were analyzed.Joinpoint regression model was used to calculate annual percentage change(APC)for time trend analysis.Results There were 1 087 cases of thyroid cancer reported in Gansu cancer registration areas from 2009 to 2015,the incidence was 2.87/100 000 and the ASR China was 2.51/100 000.The mortality was 0.86/100 000,and the ASR China was 0.80/100 000.The incidence and mortality rates were higher in females than those of males and those of rural areas than in urban areas.Incidence and mortality increase with age;The incidence and mortality of thyroid cancer showed an increasing trend from 2009 to 2015(APC=10.6%,t=2.4,P=0.10;APC=7.0%,t=1.3,P=0.30),the change trend was not statistically significant.Conclusion The incidence and mortality of thyroid cancer in Gansu province were relatively high from 2009 to 2015,and women over 50 years old in urban areas were the key targets for thyroid cancer prevention and control.
