Racial Disparities in Rising Incidence and Mortality from Uterine Cancer
MedicalResearch.com Interview with: Megan Clarke, Ph.D., M.H.S., Earl Stadtman Investigator Division of Cancer Epidemiology and Genetics National Cancer Institute MedicalResearch.com: What is the background for this study?
- Through our prior work, we have demonstrated that uterine cancer incidence rates have been significantly increasing in the U.S. from 2003 to 2015 and that these increases were primarily driven by rising rates of aggressive (non-endometrioid) subtypes of this cancer. We observed that rates of these aggressive cancers increased among all women and were more than twice as high among Non-Hispanic Black women compared to other racial and ethnic groups. Factors explaining these trends, as well as the disproportionately higher rates of these aggressive subtypes among non-Hispanic Black women, remain unclear, in part because risk factors are poorly understood.
- In addition to differences in incidence rates by race and ethnicity, we have also observed strong disparities in our prior studies, with Non-Hispanic Black women having substantially lower 5-year survival, regardless of subtype or stage at diagnosis, compared to other racial and ethnic populations.
- The next logical step, and the focus of the current study, was to evaluate how increases in the incidence of aggressive, non-endometrioid uterine cancer affects racial disparities and rates of death from uterine cancer.
