Burden of cancers in six female organs in China and worldwide

Abstract

Abstract Background: Cancers in female organs remain a substantial burden in China and worldwide. GLOBOCAN 2022 has recently updated the estimates of cancer burden. This study aims to depict the profiles of disease burden and to compare the age-specific rates of cancers in female organs in China with those in other countries. Methods: The latest estimates of incidence and mortality of cancers in female organs from various regions and countries were extracted from the GLOBOCAN 2022 database. We compared the proportion of total cases or deaths for cancers affecting six female organs and other tumor types in China and globally. Correlation analysis was conducted to evaluate the relationship between age-standardized incidence rate (ASIR) or age-standardized mortality rate (ASMR) and the Human Development Index (HDI). Additionally, age-specific rate curves were plotted for ten exemplary countries with different income levels. Results: Globally, there are varying burdens of female organ cancers, with higher incidence rates in Northern America and elevated rates of cervical cancer in Africa. Female organ cancers in China remain a significant burden due to their large proportion of the six tumors. A positive correlation between socioeconomic development and the incidence of breast, uterine corpus, ovarian, and vulvar cancers was noted, whereas a negative association between the HDI tiers and mortality rates was found for cervical and vaginal cancers. In 2022, Chinese women aged 50–54 years are experiencing high incidence rates of breast, cervix uteri, corpus uteri, and ovarian cancers. Conclusions: Cancers in female organs continue to be a significant health concern for women in China and worldwide. It is crucial to implement comprehensive prevention strategies tailored to address the increasing trend among younger individuals and reduce regional disparities.
