What does this research mean for the field?

Between 2004 and 2021, breast cancer mortality in China increased steadily among females, with rural areas experiencing significantly faster growth than urban areas, while male breast cancer mortality declined after 2010. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To evaluate temporal trends and demographic disparities in breast cancer mortality across China from 2004 to 2021.

Surveillance study reveals rising breast cancer mortality with widening rural disparities in China, highlighting structural barriers to care.

Key Points

To evaluate temporal trends and demographic disparities in breast cancer mortality across China from 2004 to 2021.
Extracted nationwide mortality surveillance data covering 110,224 recorded breast cancer deaths in China between 2004 and 2021.
Calculated crude mortality rates and age-standardized mortality rates (ASMR) stratified by sex and urban versus rural residency.
Conducted Joinpoint regression analysis to determine temporal trends and calculate average annual percent changes (AAPC).
Female crude mortality (7.26 per 100,000) substantially exceeded male rates (0.14 per 100,000) and increased steadily over time (AAPC = 2.21%, p < 0.001).
Rural crude mortality expanded at nearly three times the rate of urban mortality (AAPC = 3.19% vs. 1.09%).
Male ASMR exhibited an overall positive whole-period AAPC (7.78%, p < 0.001), but Joinpoint modeling revealed an initial rise followed by a significant decline after 2010.
