Abstract:
[Purpose]To analyze the trends of cancer incidence and mortality in Changsha City from 2018 to 2022.[Methods]Based on the annual cancer registry data of Changsha City from 2018 to 2022,SAS 9.2 software was used to calculate the crude incidence/mortality rates and age-standardized incidence/mortality rates by Chinese standard population(ASIRC/ASMRC).The age-standardized rate was standardized using the population composition of China in 2000.Join-point 4.9.0.0 software was used to fit a Log-linear regression model to calculate the average annual percentage change(AAPC)and its 95％confidence interval(CI)for trend analysis.A linear regression model was applied to calculate the contribution rate of each cancer type to the trend change,with a significance level of α=0.05.[Results]From 2018 to 2022,the crude incidence rate of malig-nant tumors in Changsha City was 367.98/105(ASIRC:232.28/105),and the crude mortality rate was 192.36/105(ASMRC:106.11/105).Both incidence and mortality rates were higher in male than those in female.The incidence and mortality rates remained relatively low before age 50 but rose rapidly thereafter:the incidence peaked in the age group of 80～84 years old,while mortality peaked in the age group of 85 years old and above.The top 5 cancers by incidence were lung cancer,female breast cancer,colorectum cancer,cervical cancer,and thyroid cancer;while the top 5 cancers by mortality were lung cancer,colorectum cancer,liver cancer,female breast can-cer,and cervical cancer.The ASIRC increased significantly in the total population(AAPC=4.71％,95％CI:3.20％～6.23％),male(AAPC=2.44％,95％CI:0.35％～4.58％),and female(AAPC=7.17％,95％CI:4.00％～10.43％).The ASMRC increased significantly in the total population(AAPC=2.94％,95％CI:0.73％～5.20％)and male(AAPC=3.37％,95％CI:1.63％～5.15％),but the trend in female was not statistically significant(P＞0.05).Contribution rate analysis showed that thyroid cancer(51.25％),female breast cancer(12.18％),lymphoma(6.02％),and oral cavity and pharyngeal can-cer(5.28％)were the main cancer types contributing to the increased ASIRC;lung cancer(26.10％),colorectum cancer(14.89％),oral cavity and pharyngeal cancer(5.73％),lymphoma(5.60％),and thyroid cancer(2.08％)were the main ones contributing to the increased ASMRC;liver cancer(49.82％)and esophageal cancer(19.55％)were the main causes of decreased ASIRC,with their contribution rates to decreased ASMRC reaching 77.69％and 11.16％,respectively.[Conclusion]The disease burden of malignant tumors in Changsha City continued to increase from 2018 to 2022.It is necessary to strengthen prevention and control for cancers with a signifi-cant upward trend(such as thyroid cancer,lung cancer,and colorectum cancer)and high-risk populations(such as male and middle-aged and elderly people),while consolidating the prevention and control effects for liver cancer and esophageal cancer.
