Factors accounting for excess uterine cancer mortality among insured Black versus White patients treated within the same US health care system

Among insured patients treated within the same US health care system, Black patients had approximately twice the mortality risk of White patients, with 70.8% of the excess relative risk of death among Black patients being attributable to tumor characteristics, 21.4% attributable to socioeconomic status, and 7.8% un-explained. Co-morbidities, diagnostic efficiency, and treatment quality were not significant contributors relative to other factors. These findings suggest that eliminating disparities in survival between Black and White patients will require development of more effective treatments for high-risk tumor types and interventions that mitigate the negative effects of lower socioeconomic status on health.
