Analysis of epidemiological characteristics of thyroid cancer incidence and mortality in Karamay City from 2015 to 2021
Objective To analyze the incidence characteristics of thyroid cancer among residents in Karamay from 2015 to 2021,to provide evidence for improving the prevention and control measures of thyroid cancer.Methods The inci-dence(mortality)data of thyroid cancer among residents in Karamay City from 2015 to 2021 were collected through the Chinese Cancer Registry Platform,and the incidence(mortality)rate,standardized incidence(mortality)rate,cumulative inci-dence(mortality)rate of thyroid cancer aged 0-74 years,truncation rate,and other indicators were calculated.The standard population was based on the 2000 national census data and Segi's world standard population.Joinpoint software was used for standardized morbidity and mortality characteristics of thyroid cancer,and SAS software was used for survival analysis.Results From 2015 to 2021,the crude incidence rate of thyroid cancer residents in Karamay City was 44.87/105,the win-ning rate was 33.00/105,the world standard rate was 28.30/105,the accumulation rate of 0-74 years old was 2.68％,and the truncation rate was 71.20％.The crude mortality rate of thyroid cancer was 1.73/105,the winning rate was 1.13/105,the world standard rate was 1.03/105,the accumulation rate of 0-74 years old was 0.10％,and the truncation rate was 2.05％.The crude incidence of thyroid cancer in women was 64.57/105,which was higher than that in men(25.50/105),and the difference was statistically significant(x2=177.79,P＜0.001),the winning rate was 2.4 times that of men,and the world standard rate was 2.5 times that of men.The mortality rate of thyroid cancer was 1.74/105 in women and 1.71/105 in men,and the differ-ence was not statistically significant(x2=0.033,P=0.959).Conclusion The incidence of thyroid cancer residents in Kara-may is higher than that of the national level,and the inci-dence rate of women is higher than that of men,so great at-tention should be paid to the prevention and control of thy-roid cancer.
