Black/white differences in treatment and survival among women with stage IIIB–IV breast cancer at diagnosis: A US population-based study
Cancer Causes and Control Jun 09, 2018
Enewold L, et al. - Because poorer survival has been reported in non-Hispanic black (NHB) women with breast cancer vs non-Hispanic white (NHW) women, researchers investigated if racial disparities exist among women diagnosed with late-stage breast cancer, especially if care is provided in the community setting. This study included 533 women with stage IIIB–C and 625 with stage IV tumors, with NHW women making up about 70% of each group. No racial/ethnicity variations in systemic treatment among women with stage IIIB–C disease were seen; however, a borderline correlation was noted indicating worse all-cause mortality among NHB women. On the other hand, among women with stage IV disease, borderline associations indicating NHB women were more likely to receive chemotherapy and, among those with hormone receptor-positive tumors, less likely to receive endocrine therapy. In terms of all-cause mortality, no variation by race/ethnicity for stage IV disease was noted.
