In this article, the American Cancer Society provides an overview of female breast cancer statistics in the United States, including data on incidence, mortality, survival, and screening. Approximately 252,710 new cases of invasive breast cancer and 40,610 breast cancer deaths are expected to occur among US women in 2017. From 2005 to 2014, overall breast cancer incidence rates increased among Asian/Pacific Islander (1.7% per year), non‐Hispanic black (NHB) (0.4% per year), and Hispanic (0.3% per year) women but were stable in non‐Hispanic white (NHW) and American Indian/Alaska Native (AI/AN) women. The increasing trends were driven by increases in hormone receptor‐positive breast cancer, which increased among all racial/ethnic groups, whereas rates of hormone receptor‐negative breast cancers decreased. From 1989 to 2015, breast cancer death rates decreased by 39%, which translates to 322,600 averted breast cancer deaths in the United States. During 2006 to 2015, death rates decreased in all racial/ethnic groups, including AI/ANs. However, NHB women continued to have higher breast cancer death rates than NHW women, with rates 39% higher (mortality rate ratio [MRR], 1.39; 95% confidence interval [CI], 1.35‐1.43) in NHB women in 2015, although the disparity has ceased to widen since 2011. By state, excess death rates in black women ranged from 20% in Nevada (MRR, 1.20; 95% CI, 1.01‐1.42) to 66% in Louisiana (MRR, 1.66; 95% CI, 1.54, 1.79). Notably, breast cancer death rates were not significantly different in NHB and NHW women in 7 states, perhaps reflecting an elimination of disparities and/or a lack of statistical power. Improving access to care for all populations could eliminate the racial disparity in breast cancer mortality and accelerate the reduction in deaths from this malignancy nationwide.

2017 年乳腺癌统计数据，各州死亡率的种族差异

在本文中，美国癌症协会概述了美国女性乳腺癌的统计数据，包括发病率、死亡率、存活率和筛查数据。预计 2017 年美国女性将发生大约 252,710 例浸润性乳腺癌新病例和 40,610 例乳腺癌死亡。从 2005 年到 2014 年，亚洲/太平洋岛民、非西班牙裔黑人的乳腺癌总体发病率增加（每年 1.7%） (NHB)（每年 0.4%）和西班牙裔（每年 0.3%）女性，但在非西班牙裔白人 (NHW) 和美洲印第安人/阿拉斯加原住民 (AI/AN) 女性中保持稳定。增长趋势是由激素受体阳性乳腺癌的增加驱动的，在所有种族/族裔群体中均有所增加，而激素受体阴性乳腺癌的发病率有所下降。从 1989 年到 2015 年，乳腺癌死亡率下降了 39%，这意味着在美国避免了 322,600 例乳腺癌死亡。2006 年至 2015 年期间，包括 AI/AN 在内的所有种族/族裔群体的死亡率均有所下降。然而，NHB 女性的乳腺癌死亡率继续高于 NHW 女性，2015 年 NHB 女性的死亡率高出 39%（死亡率比 [MRR]，1.39；95% 置信区间 [CI]，1.35-1.43），尽管自 2011 年以来，这种差距不再扩大。 按州划分，黑人女性的超额死亡率从内华达州的 20%（MRR，1.20；95% CI，1.01-1.42）到路易斯安那州的 66%（MRR，1.66；95% CI）不等, 1.54, 1.79)。值得注意的是，7 个州的 NHB 和 NHW 女性的乳腺癌死亡率没有显着差异，这可能反映了差异的消除和/或缺乏统计效力。改善所有人群获得护理的机会可以消除乳腺癌死亡率的种族差异，并在全国范围内加速减少这种恶性肿瘤的死亡人数。CA Cancer J Clin 2017；67：439-448。© 2017 美国癌症协会。
