It is well known that there is a significant racial divide in breast cancer incidence and mortality rates. African American women are less likely to be diagnosed with breast cancer than white women but are more likely to die from it. This review explores the factors that may contribute to the racial survival disparity. Consideration is paid to what is known about the role of differences in tumor biology, genomics, cancer screening, and quality of cancer care. It is argued that it is the collision of 2 forces, tumor biology and genomics, with patterns of care that leads to the breast cancer mortality gap. The delays, misuse, and underuse of treatment for African American patients are of increased significance when these patients are presenting with more aggressive forms of breast cancer. In the current climate of health care reform ushered in by the Affordable Care Act, this article also evaluates interventions to close the disparity gap. Prior interventions have been too narrowly focused on the patient rather than addressing the system and improving care across the continuum of breast cancer evaluation and treatment. Lastly, areas of future investigation and policy initiatives aimed at reducing the racial survival disparity in breast cancer are discussed.
众所周知,乳腺癌的发病率和死亡率存在显著的种族差异。与白人女性相比,非裔美国女性被诊断出患有乳腺癌的可能性较低,但死于乳腺癌的可能性较高。本综述探讨了可能导致种族生存差异的因素。考虑到已知的肿瘤生物学、基因组学、癌症筛查和癌症治疗质量方面的差异的作用。有人认为,正是肿瘤生物学和基因组学与护理模式的碰撞导致了乳腺癌死亡率的差距。当非裔美国患者出现更具侵袭性的乳腺癌时,治疗的延迟、误用和使用不足对他们的影响更为显著。在平价医疗法案(Affordable Care Act)带来的医疗改革的大环境下,本文还评估了缩小差距的干预措施。以前的干预措施过于狭隘地关注患者,而没有解决系统问题,也没有改善乳腺癌评估和治疗全过程中的护理。最后,讨论了未来旨在减少乳腺癌种族生存差异的调查领域和政策倡议。
