Abstract:
[Purpose]To analyze the incidence and mortality of liver cancer in cancer registration areas of Zhejiang Province in 2021 and the epidemiological trends of liver cancer from 2000 to 2021.[Methods]Using liver cancer data from 2000 to 2021 reported by Zhejiang Provincial Can-cer Registries,stratified by sex,age,and urban-rural areas,indicators including crude incidence rate,crude mortality rate,age-standardized incidence rate by Chinese standard population(ASIRC),age-standardized mortality rate by Chinese standard population(ASMRC),age-standardi-zed incidence rate by world standard population(ASIRW),age-standardized mortality rate by world standard population(ASMRW)were calculated.Joinpoint Regression Program(Version 5.3.0)was used to fit the log-linear relationship between rates and years,and calculate the annual percentage change(APC)and average annual percentage change(AAPC)with 95％confidence interval(CI).[Results]In 2021,the crude incidence rate of liver cancer in Zhejiang cancer registration areas was 26.93/105(ASIRC:13.35/105),and the crude mortality rate was 20.87/105(ASMRC:9.52/105).The number of new cases and deaths of liver cancer accounted for 5.07％and 11.33％of all malig-nant tumor cases and deaths,respectively.The incidence and mortality rates of liver cancer in male were significantly higher than those in female(crude incidence rate:40.17/105 vs 13.85/105;ASIRC:20.60/105 vs 6.34/105;crude mortality rate:30.78/105 vs 11.07/105;ASMRC:14.67/105 vs 4.57/105),and those in rural areas were higher than those in urban areas(crude incidence rate:30.39/105 vs 24.79/105;ASIRC:15.35/105 vs 12.10/105;crude mortality rate:24.32/105 vs 18.72/105;ASMRC:11.30/105 vs 8.40/105).In 2021,the incidence rate of liver cancer was low before the age of 30 years old,and increased significantly with age after 30 years old,reaching the peak in male aged 85 years old and above(170.04/105)and in female aged 80～84 years old(84.74/105).The mortality rate showed a similar trend to the incidence rate,which was low before the age of 30 years old and increased significantly with age after 30 years old,peaking in male aged 85 years old and above(211.64/105)and in female aged 80～84 years old(98.31/105).From 2000 to 2021,the crude incidence rate of liver cancer in Zhejiang Province showed an overall upward trend(AAPC=1.01％,95％CI:0.44％～1.58％),while the ASIRC remained relatively stable(AAPC=-0.81％,95％CI:-1.48％～0.02％)with a significant remained relatively stable(AAPC=-0.81％,95％CI:-1.48％～0.02％),after 2010,the ASIRC remained relatively stable(AAPC=-0.81％,95％CI:-1.48％～0.02％)with a significant decreased significantly.Both the crude mortality rate(AAPC=-0.84％,95％CI:-1.23％～-0.36％)and ASMRC(AAPC=-2.78％,95％CI:-3.28％～-2.20％)showed sig-nificant downward trends,and the decline of ASMRC was more obvious.[Conclusion]From 2000 to 2021,the incidence of liver cancer in cancer registration areas of Zhejiang Province showed a fluctuating downward trend,and the mortality showed a steady downward trend,but the disease burden remains heavy.Rural areas,the elderly,and males are high-risk populations,which should be the key targets of liver cancer prevention and control.
