Abstract:
Objective To analyze the trends in disease burden of breast cancer and cervical cancer among Chinese women from 1990 to 2021 and make predictions, so as to provide evidence for prevention of breast cancer and cervical cancer.
Methods Data on the incidence, death, and disability-adjusted life-years (DALYs) of breast cancer and cervical cancer among women in China were collected from the Global Burden of Disease (GBD) 2021 database. The estimated annual percentage change (EAPC) was calculated to assess the trends in disease burden of breast cancer and cervical cancer among women in China from 1990 to 2021. Bayesian age-period-cohort analysis was used to predict the disease burden of breast cancer and cervical cancer among women in China from 2022 to 2031.
Results In 2021, the age-standardized incidence rate (ASIR), age-standardized mortality rate (ASMR), and age-standardized DALY rate (ASDR) of breast cancer among women in China were 37.0, 8.2, and 281.5 per 100,000, respectively, with EAPCs of 2.3%, −0.6%, and −0.5% from 1990 to 2021. The ASIR, ASMR, and ASDR of cervical cancer were 13.4, 4.6, and 149.8 per 100 000, respectively, with EAPCs of 0.9%, −1.0%, and −1.1% from 1990 to 2021. The disease burden of breast cancer and cervical cancer was higher among women aged 50 – 59 years. The predictive analysis showed that the ASIR of breast cancer among women in China would continue to increase, while the ASMR and ASDR would remain stable from 2022 to 2031. The ASIR, ASMR, and ASDR of cervical cancer were projected to decline.
Conclusion Despite an increase in the incidence of breast cancer and cervical cancer among women in China, 1990 — 2021, the death and DALYs caused by breast cancer and cervical cancer have significantly decreased, reflecting the substantial contributions made by China in promoting the prevention of breast cancer and cervical cancer. In the future, it remains an important issue in the field of maternal and child health to continue strengthening the etiological prevention and early detection, diagnosis and treatment of breast cancer and cervical cancer, especially screening for these cancers among high-risk populations.
