Abstract:
[Purpose]To analyze the trend of bladder cancer incidence and age at diagnosis in can-cer registration areas of Jiangsu Province from 2009 to 2019.[Methods]The data of bladder can-cer incidence from 2009 to 2019 were collected from 16 cancer registries in Jiangsu Province,and quality control indicators of the data were evaluated.The crude rate(CR)of incidence,age-standar-dized incidence rate by Segi world standard population(ASIRW),age-specific incidence rate,mean age at diagnosis,mean standardized age at diagnosis,and age-specific incidence composi-tion ratio were calculated.Incidence trends were analyzed using Joinpoint software and the average annual percentage change(AAPC)was calculated.Birth cohort models were constructed and can-cer incidence rates were calculated for people born from 1929 to 2019 and the incidence trends were analyzed.The linear regression models were used to analyze the relationship of average age at onset,standardized average age of onset with year of onset.[Results]The CR of bladder cancer in Jiangsu Province increased from 4.27/105 in 2009 to 7.04/105 in 2019.The CR and ASIRW showed upward trends(CR:AAPC=4.62％,ASIRW:AAPC=1.92％,both P＜0.001).Sex-specific analysis showed that the incidence rate was higher in male(AAPC=5.32％)than that in female(AAPC=1.98％).Birth cohort results indicated a significant upward trend in incidence rates among age groups of 60 years old above,and the fastest increase was in those aged 80 years old and above(AAPC=3.27％,P=0.007).From 2009 to 2019,the average age of bladder cancer onset in Jiangsu Province showed a significant rising trend,increasing by an average of 0.17 years old annually,but the standardized average age of onset showed no significant change after adjusting for age structure.[Conclusion]The incidence rate of bladder cancer showed an increasing trend from 2009 to 2019 in Jiangsu Province,with a significantly higher incidence rate in male than that in female.
