Abstract:
[Purpose]To analyze the trend of gastric cancer incidence and age characteristics in Jiangsu cancer registration areas from 2009 to 2019.[Methods]Cancer registration data from 2009 to 2019 meeting quality control requirements were collected from 16 cancer registries in Jiangsu Province.The crude incidence rate and age-standardized incidence rate by Chinese standard population in 2000(ASIRC)were calculated by gender,urban/rural areas and age groups.The inci-dence trends were analyzed by Joinpoint.A birth cohort model was constructed to calculate the in-cidence rate of gastric cancer for men and women born between 1929 and 2019.The age composi-tion of gastric cancer incidence in Jiangsu Province between 2009 and 2019 was calculated and compared.[Results]The crude incidence rate and ASIRC of gastric cancer in Jiangsu cancer regi-stration areas from 2009 to 2019 showed a significant decreasing trend in both male and female or urban and rural areas,in which the decrease in male(AAPC=-1.28％,P＜0.001)was higher than that of female(AAPC=-1.17％,P=0.030),and the decrease in urban(AAPC=-1.66％,P＜0.001)was higher than that of rural(AAPC=-0.72％,P＜0.001).The incidence rates of gastric cancer in age groups of 40～79 years old showed a significant decreasing trend from 2009 to 2019 with the AAPC ranging from-6.75％to-3.54％(all P＜0.05).In age groups of 40～79 years old,the inci-dence rates of gastric cancer among people with different years of birth showed a decreasing trend with the increase of the birth year.For ASIRC,the composition of patients aged 60 years old above increased by 0.63％(95％CI:0.46％～0.81％)per year from 2009 to 2019.[Conclusion]The inci-dence rate of gastric cancer in cancer registration areas of Jiangsu Province from 2009 to 2019 showed a decreasing trend,the average age of incidence showed a trend of backward moving,and for age-standardized incidence the proportion of patients over 60 years old was increased.
