In this article, the American Cancer Society provides the estimated number of new cancer cases and deaths for blacks in the United States and the most recent data on cancer incidence, mortality, survival, screening, and risk factors for cancer. Incidence data are from the National Cancer Institute, the Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries, and mortality data are from the National Center for Health Statistics. Approximately 189,910 new cases of cancer and 69,410 cancer deaths will occur among blacks in 2016. Although blacks continue to have higher cancer death rates than whites, the disparity has narrowed for all cancers combined in men and women and for lung and prostate cancers in men. In contrast, the racial gap in death rates has widened for breast cancer in women and remained level for colorectal cancer in men. The reduction in overall cancer death rates since the early 1990s translates to the avoidance of more than 300,000 deaths among blacks. In men, incidence rates from 2003 to 2012 decreased for all cancers combined (by 2.0% per year) as well as for the top 3 cancer sites (prostate, lung, and colorectal). In women, overall rates during the corresponding time period remained unchanged, reflecting increasing trends in breast cancer combined with decreasing trends in lung and colorectal cancer rates. Five-year relative survival is lower for blacks than whites for most cancers at each stage of diagnosis. The extent to which these disparities reflect unequal access to health care versus other factors remains an active area of research. Progress in reducing cancer death rates could be accelerated by ensuring equitable access to prevention, early detection, and high-quality treatment.

本文由美国癌症协会提供了美国黑人癌症新发病例和死亡人数的估计数,以及癌症发病率、死亡率、生存率、筛查和癌症风险因素的最新数据。发病率数据来自美国国家癌症研究所、疾病控制和预防中心以及北美癌症登记协会,死亡率数据来自国家卫生统计中心。2016 年,美国黑人中约有 189910 例新癌症病例和 69410 例癌症死亡。尽管黑人的癌症死亡率仍然高于白人,但男性和女性所有癌症、肺癌和前列腺癌的死亡率差距已经缩小。相比之下,女性乳腺癌的死亡率差距在扩大,而男性结肠癌的死亡率差距则保持不变。自 20 世纪 90 年代初以来,整体癌症死亡率的下降意味着避免了 30 多万名黑人的死亡。在男性中,2003 年至 2012 年所有癌症的发病率(每年下降 2.0%)以及前 3 大癌症部位(前列腺、肺和结直肠)的发病率都有所下降。在女性中,同期的总体发病率保持不变,这反映了乳腺癌的发病率上升,同时肺癌和结直肠癌的发病率下降。在每个诊断阶段,黑人的 5 年相对生存率都低于白人。这些差异在多大程度上反映了获得医疗保健的不平等,而不是其他因素,仍然是一个活跃的研究领域。通过确保公平获得预防、早期发现和高质量治疗,可以加速降低癌症死亡率的进展。CA Cancer J Clin 2016;66:290-308。© 2016 美国癌症协会。
