美国癌症协会的研究发现大肠癌死亡率下降慢在非洲裔美国人

非裔美国人在1980年之前,结直肠癌死亡率低于白人。然而自那时起,CRC死亡率已经逆转,分化的模式,所以,在2007年,非裔美国人比白人高出44%。这个死亡率差距恶化之际,引进和传播的结直肠癌筛查和改善治疗。研究显示传播治疗结直肠癌筛查和改善的非洲裔美国人已经落后于白人。然而,黑白不平等的程度在死亡率随阶段诊断是未知的。为了找到答案,美国癌症协会的研究人员由安东尼·罗宾斯,医学博士博士,检查stage-specific大肠癌死亡率的差异使用Incidence-Based死亡率数据库国家癌症研究所的监测、流行病学、最终结果(SEER)计划。他们发现为本地化阶段,死亡率下降30.3%的白人和13.2%的非裔美国人。区域疾病阶段,分别下跌48.5%和34.0%。遥远的阶段,减少32.6%,仅为4.6%。 The data indicates that black-white disparities in colorectal cancer mortality increased for each stage of the disease, and that the overall disparity in overall mortality was largely driven by trends for late stage disease. “The widening racial disparity for distant stage has a disproportionate impact on overall CRC mortality disparities because distant stage accounts for approximately 60% of the overall black-white mortality disparity,” write the authors. As to why, the authors cite differences in early detection and differences in treatment. African Americans have historically been less likely than whites to be screened for colorectal cancer. In addition, African Americans who are screened often lack timely follow-up. Meanwhile, studies show the dissemination of improvements in treatment has been uneven. Despite its known survival benefit, adjuvant chemotherapy treatment rates among African American patients with colorectal cancer are disproportionately low relative to whites. ACS19849
