Abstract:
Objective To analyze the mortality level of malignant tumors among residents with Jinhua household registration, predict the development trend of malignant tumors, and provide scientific basis for the prevention and control of malignant tumors in Jinhua, Zhejiang province.
Methods The mortality surveillance data of malignant tumors in Jinhua from 2016 to 2024 were collected. The epidemiological characteristics and changing trends of crude mortality rate, standardized mortality rate, potential years of life lost (PYLL), average years of life lost (AYLL), PYLL rate (PYLLR), and cause-of-death ranking were statistically analyzed. The changing trend of malignant tumor mortality in Jinhua from 2025 to 2027 was predicted.
Results From 2016 to 2024, the crude mortality rate of malignant tumors in Jinhua was 180.28/100 000, and the standardized mortality rate was 110.00/100 000. The crude mortality rate was relatively stable, while the standardized mortality rate showed a downward trend average annual percentage change (AAPC)=−3.33%, P<0.001. Among them, the crude mortality rate for men was 235.87/100 000, and the standardized mortality rate was 139.59/100 000. The crude mortality rate for women was 123.33/100 000, and the standardized mortality rate was 77.50/100 000. The standardized mortality rate for men was higher than that for women (χ2=7777.410, P<0.001). The standardized mortality rates for both men and women showed a downward trend (AAPC=−3.34% , −3.20%, P<0.001). The PYLL and PYLLR for men were higher than those for women, but the AYLL for women was higher than that for men. Among the top 10 malignant tumors with the highest standardized mortality rates, the standardized mortality rates of lung cancer (AAPC=−4.23%, P<0.001), liver cancer (AAPC=−5.33%, P<0.001), gastric cancer (AAPC=−5.89%, P<0.001), esophageal cancer (AAPC=−8.16%, P<0.001), and cervical cancer (AAPC=−2.49%, P=0.036) showed a downward trend, with esophageal cancer having the largest decline. It is predicted that the overall standardized mortality rate of malignant tumors in Jinhua will continue to decline from 2025 to 2027 (AAPC=−3.26%, P<0.001).
Conclusion The standardized mortality rate of malignant tumors in Jinhua from 2016 to 2024 showed a downward trend, but the disease burden remained high. Comprehensive prevention and control efforts should be strengthened for key malignant tumors.
