“…In the literature, Asian women consistently demonstrate lower mortality rates than NHW women, 20‐23 but when analyzed by region of origin, some subgroups had mortality rates that were higher than other Asian groups and comparable to NHW women 21,23‐25 . In our study, being Asian was associated with better adjusted OS and CSS both in aggregate and when disaggregated into specific Asian ethnicities compared with other racial/ethnic groups in the United States with 1 notable exception: SE Asian women fared worse than women from other Asian subgroups and fared similar to NHW women.…”

Background Asian women with breast cancer are often studied in aggregate, belying significant intragroup diversity. The authors sought to examine differences in breast cancer characteristics and outcomes among Asian women. Methods Asian, non‐Hispanic Black, Hispanic, and non‐Hispanic White women aged 18 years and older who were diagnosed with breast cancer from 1990 to 2016 were identified in the Surveillance, Epidemiology, and End Results 18 database. Asian patients were subclassified as Chinese, Japanese, Korean, Filipino, Vietnamese, South Asian (Asian Indian or Pakistani), Southeast Asian (SEA, i.e., Cambodian, Laotian, Hmong, or Thai), or other Asian. Unadjusted overall survival (OS) and cancer‐specific survival (CSS) were estimated using the Kaplan‐Meier method. Cox proportional hazards models were used to estimate adjusted OS and CSS. Results In total, 910,415 women were included (Asian, n = 63,405; Black, n = 92,226; Hispanic, n = 84,451; White, n = 670,333). Asian women had higher rates of human epidermal growth factor receptor 2 (HER2)‐positive disease compared with White women (18.7% vs 13.8%) and had the highest 10‐year unadjusted OS and CSS among all racial/ethnic groups (all P < .001). SEA women had the highest rates of stage IV disease at presentation, whereas Japanese women had the lowest rates (5.9% vs 2.7%; P < .001). Japanese women had the highest 10‐year unadjusted CSS (89.4%; 95% confidence interval, 88.7%‐90.1%) of any distinct Asian group, whereas SEA women had the worst unadjusted CSS (78%; 95% confidence interval, 74.1%‐81.3%; P < .001). After adjustment, SEA women had the worst OS of any Asian group and were the only Asian group without improved OS compared with White women (reference category; P = .08). Conclusions Breast cancer characteristics and outcomes vary significantly among Asian women. Future research should consider disaggregation by country or region of origin to identify subgroups that are at risk for worse outcomes than aggregated data may suggest. Lay Summary Asian women with breast cancer are frequently studied as a single entity. However, Asian ethnic groups differ greatly by country of origin, genetic ancestry, disease frequency, socioeconomic status, patterns of immigration, as well as dietary and cultural practices. Women of different Asian ethnicities vary significantly with regard to cancer characteristics, such as mortality and tumor subtype. Future research should disaggregate these populations to better understand, treat, and counsel Asian patients with breast cancer.

“…Comprehensive analyses demonstrating the leading causes of disease nationally, by disaggregated Asian American subgroups, have not been updated in 10 years. 11,12,28 Regardless, current disaggregated research reveals clear differences from the Asian American aggregate data, which demands improved epidemiological data efforts at national, state, and local levels to accurately determine differentials in health risks among these subgroups.…”

In this manuscript, we discuss critical health outcome differences between the 6 major Asian American subgroups (Asian Indian, Chinese, Filipino, Japanese, Korean, and Vietnamese) and highlight the critical issues that contribute to the Asian American health disparity gap. We also propose approaches to address these critical issues, with approaches shown effective in other populations.By considering these approaches, we hope that stakeholders of Asian American health outcomes can steer current health research agendas and efforts towards improving Asian health equity.
