Abstract:
[Purpose]To analyze the incidence and mortality of lung cancer in Zhejiang cancer regi-stration areas in 2021 and trends from 2000 to 2021.[Methods]Using data from Zhejiang cancer registration areas from 2000 to 2021,the crude rate,age-standardized rate by Chinese standard population(ASRC)and the world standard population(ASRW),and composition ratio were calcu-lated to describe the incidence and mortality in 2021.Joinpoint regression was employed to ana-lyze temporal trends over the 22 years,calculating the annual percentage change(APC),average annual percentage change(AAPC),and their 95％confidence intervals(CI).[Results]The crude incidence rate of lung cancer in 2021 was 128.58/105,with an ASRC of 68.74/105,ac-counting for 24.22％of all cancers;the crude mortality rate was 51.55/105,with an ASRC of 21.58/105,constituting 27.98％of all cancer deaths.Both crude incidence rate(AAPC=5.73％,P＜0.001)and ASIRC(AAPC=4.14％,P＜0.001)of lung cancer showed significant increasing trends from 2000 to 2021.The crude mortality rate increased slowly(AAPC=1.76％,P＜0.001),while the ASMRC(AAPC=-0.40％,P=0.035)exhibited a modest decline.The increase in incidence was more pronounced in females than males,though no statistically significant difference was observed in mortality trends.The incidence rates in urban and rural areas showed similar growth trends;the crude mortality rate in rural areas was growing significantly faster than that in urban areas,and the decline in the ASRC was only statistically significant in urban areas.The incidence rate was in-creasing in all age groups.The mortality rate was declining among younger people(＜65 years old).The age group of 15～44 years old demonstrated a greater increase in incidence and a sharper decline in mortality than those aged 45 years old and above.[Conclusion]From 2000 to 2021,Zhejiang Province experienced a marked rise in lung cancer incidence with escalating disease burden.Despite severe population aging,ASRC of mortality declined steadily,reflecting effective prevention and control measures.
