Compared with white women, Black women have elevated risks of being diagnosed with advanced uterine cancer—also known as endometrial cancer—and of developing aggressive tumours.
Researchers recently compared the incidence and trends for endometrial cancer, both overall and by subtype, between African descent women in Florida and women in the French Caribbean—specifically, the islands of Martinique and Guadeloupe. The findings are published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society.
Endometrial cancer is classified as endometrioid or non-endometrioid (a more aggressive form) based on tumour cells’ appearance and genetic alterations. When Heidy N. Medina, PhD, MPH, of the University of Miami School of Medicine, and her colleagues analysed data on 34,789 endometrial cancer cases from Florida (US) and the French Caribbean from 2005–2018, they observed the following:
“This study informs the current scientific evidence about endometrial cancer risk among a diverse sample of African descent women, highlighting that within group differences matter among Black women,” said Dr. Medina. “Our study suggests that these differences among Black women in different regions of the world are partly due to social factors associated with assigned race rather than purely African ancestry–related factors based on genetic origin.”
Dr. Medina added that the study emphasises the need to not generalise results from Black women in the US to other African descent populations worldwide where limited data exist. “This signals the need for coordinated efforts around the world in identifying disparities, emphasising the importance of strong cancer surveillance systems and registries throughout different regions, and the necessity for there to be a greater priority among the global health community in allocating resources to improve data collection for cancer registries worldwide,” she said.
Dr. Medina also stressed the importance of tracking the increasing rates of the deadlier non-endometrioid types of endometrial cancer and identifying risk factors associated with these malignancies.
