Racial and Ethnic Disparities in Outcomes After Breast-Conserving Therapy and Endocrine Therapy for DCIS: A Post-Hoc Analysis of the NSABP B-35 Randomized Clinical Trial.

Racial and ethnic disparities in outcomes after treatment for ductal carcinoma in situ (DCIS) are largely unknown. The objective of this study was to examine breast cancer outcomes by race and ethnicity in the National Surgical Adjuvant Breast and Bowel Project (NSABP) B-35 clinical trial. The NSABP B-35 trial randomized postmenopausal women with hormone receptor-positive DCIS treated with breast-conserving therapy to 5 years of tamoxifen or anastrozole. In total, 3104 women were enrolled between 2003 and 2006. For this analysis, patients without complete self-reported race and ethnicity or with immediate trial dropout were excluded. Kaplan-Meier curves and adjusted Cox-proportional hazards models were used for analyses. Of the 3061 women included, 2614 (85.4%) were non-Hispanic white (NHW), 255 (8.3%) were non-Hispanic Black (NHB), 95 (3.1%) were Hispanic, and 96 (3.1%) were Asian or Pacific Islander (API). Endocrine therapy assignment and duration were well balanced between racial and ethnic groups. Median follow-up was 9 years; unadjusted Kaplan-Meier curves did not show any racial differences in disease events. Adjusted Cox-proportional hazards models found API (versus NHW) race to be associated with higher local recurrence [hazard ratio (HzR) 2.45, p = 0.035] and NHB race to be associated with higher distant recurrence (HzR 5.03, p = 0.020) and breast cancer mortality (HzR 3.83, p = 0.046). Despite similar locoregional treatments and standard endocrine therapy in a clinical trial population, racial and ethnic disparities exist in long-term outcomes for hormone-receptor-positive DCIS. These findings suggest that factors outside of access and treatment may impact DCIS outcomes by race and ethnicity.

Racial and Ethnic Disparities in Health-Related Quality of Life for Patients with Colorectal Cancer: Analysis of the SEER-MHOS Linked Data Set

We hypothesized that racial and ethnic disparities exist in health-related quality of life (HRQOL) among older adults with colorectal cancer, both before and after diagnosis. The Surveillance, Epidemiology, and End Results and Medicare Health Outcomes Survey (SEER-MHOS) linked data set was used to identify patients 65 years old and above who were diagnosed with colorectal cancer between 1996 and 2015. Self-reported race/ethnicity, the predictor of interest, was categorized as White (W), Asian/Pacific Islander (API), Black/African American (B), or Hispanic (H). HRQOL data from the 36-Item Short Form Survey and Veterans RAND 12-Item Health Survey were extracted within 24 months pre- and post-diagnosis. HRQOL was measured using the Physical Component Summary (PCS), Mental Component Summary (MCS), and Total Component Summary (TCS, a summation of PCS and MCS), which were the response variables. Associations were assessed via univariable (UVA) and multivariable (MVA) linear regression analysis, adjusting for age, sex, region, marital status, education, income, number of comorbidities, limitations in activities of daily living, stage, and histology. Pairwise comparisons were performed between all racial and ethnic groups. We identified a total of 1,204 evaluable patients, with 815 in the pre-diagnosis cohort and 562 in the post-diagnosis cohort, including 173 patients in both. With unadjusted p-values, pre-diagnosis UVA revealed a higher mean PCS in API patients compared to W, B, and H patients (p<0.001, p<0.001, p = 0.02) as well as in W compared to H patients (p = 0.002); a higher mean MCS in W and API patients compared to B (p<0.001, p = 0.002) and H patients (p<0.001, p = 0.002); and a higher mean TCS in API compared to W, B, and H patients (p = 0.027, p<0.001, p<0.001) as well as in W compared to B and H patients (p<0.001, p = 0.012). Pre-diagnosis MVA revealed a higher mean PCS in API compared to B patients (p = 0.028) and a higher mean MCS in W and B compared to H patients (p = 0.022, p = 0.021). Post-diagnosis UVA showed a higher mean MCS in W compared to B and H patients (p<0.001 for both) as well as in API compared to H patients (p = 0.002), and a higher mean TCS in W and API patients compared to B (p<0.001, p = 0.045) and H patients (p<0.001, p = 0.007). Post-diagnosis MVA showed a higher mean MCS in API compared to H patients (p = 0.035). Compared to pre-diagnosis, post-diagnosis mean TCS was numerically lower for all groups. Among older adults with colorectal cancer, there appear to be racial and ethnic disparities in HRQOL. Before the cancer diagnosis, API patients had better physical HRQOL than B patients, while W and B patients had better mental HRQOL than H patients. After diagnosis, API patients had better mental HRQOL than H patients. For all groups, the cancer diagnosis seemed to have a negative impact on overall HRQOL.

Trends in Racial and Ethnicity Disparities in the Health-Related Quality of Life in Older Adults with Breast Cancer: A SEER-MHOS National Database Study

To examine racial and ethnic disparities in Health-Related Quality of Life (HRQOL) in older adults with breast cancer, both pre- and post-diagnosis. Using the Surveillance, Epidemiology and End Results-Medicare Health Outcomes Survey (SEER-MHOS) database, we included patients > 65 years old with breast cancer diagnosed from 1998-2019, who had completed the Health Outcomes Survey within 24 months pre- and post-diagnosis, and who had a reported ethnicity of non-Hispanic White (W), non-Hispanic Asian or Pacific Islander (API), non-Hispanic Black or African American (B), or Hispanic (H). HRQOL data was measured by the Physical Component Summary (PCS) and Mental Component Summary (MCS) scores from the Medical Outcomes Study Short Form-36 and the Veterans RAND 12-Item Health Survey instruments. Univariable (UVA) and multivariable (MVA) linear regression models were fitted for MCS, PCS, and TCS (composite MCS and PCS) as response variables to assess for potential disparities between races and ethnicities. MVA models were adjusted for sex, age, marital status, education, income, number of comorbidities, limitations in activities of daily living, national region, histology, and treatment type (in post-diagnosis cohort only). We identified 1,008 in the pre-diagnosis cohort (56.6% stage I, 29.8% stage II, 9.3% stage III, and 4.3% stage IV) and 991 patients in the post-diagnosis cohort (58.3% stage I, 28.6% stage II, 9.3% stage III, 3.8% stage IV). On UVA, differences in mean scores of TCS, PCS, and MCS, respectively, were found among W, API, B, and H patients in both pre-diagnosis and post-diagnosis cohorts (pre-diagnosis - TCS: 93.4, 93.0, 87.0, 86.3; PCS: 40.3, 40.0, 37.0, 37.5; MCS: 53.1, 52.9, 50.0, 48.7; post-diagnosis - TCS: 90.8, 90.3, 84.3, 83.5; PCS: 38.5, 39.2, 36.8, 34.5; MCS: 52.3, 51.1, 49.8, 46.8; all p < .001). A drop in PCS, MCS, and TCS scores numerically was observed for all groups. Among patients in the pre-diagnosis cohort who would be diagnosed with stage IV breast cancer, race was found to be a predictor of PCS with overall significance (p = 0.04) within MVA linear regression. Specifically, on the local test, compared to B, W had higher pre-diagnosis PCS scores (+13.32, p = 0.03). Race was not found to be a predictor in PCS, MCS, or TCS scores otherwise. Among older patients who would be diagnosed with stage IV breast cancer, W had better physical HRQOL as compared to B patients' pre-diagnosis. The decrease in numerical HRQOL scores of the physical domain in all groups post-diagnosis highlights the potential negative physical impact breast cancer has on patients, demonstrating the need for determining the proper resources and support to improve physical HRQOL following diagnosis.

Disparities in Breast-Conserving Therapy vs. Mastectomy among Asian American and Pacific Islander Women

Multiple randomized trials support the use of breast-conserving therapy (BCT), defined as lumpectomy followed by adjuvant radiotherapy, as an alternative to mastectomy for definitive treatment of early-stage (T1-2N0) breast cancer. However, data suggest that Asian American, Native Hawaiian, and Pacific Islander (AANHPI) may undergo mastectomy at higher rates than BCT and may experience barriers to receipt of BCT. The purpose of this study was to examine BCT utilization by disaggregated AANHPI groups to identify differences in receipt of mastectomy versus BCT. The 2004-2017 National Cancer Database was queried to identify women age ≥18 years old diagnosed with cT1-2N0M0 breast cancer treated with either BCT or mastectomy without post-mastectomy radiation therapy. Women were classified based on self-reported race. Multivariable logistic regression defined adjusted odds ratios (OR) assessing the association between race and receipt of BCT versus mastectomy for all patients and separately by cT1-2 stage. All models were adjusted for relevant sociodemographic and clinical factors. Of 794,403 women with cT1-2N0M0 breast cancer, 239,801 (30%) received mastectomy and 554,602 (70%) received BCT. After adjusting for clinical and sociodemographic factors, AANHPI women had greater odds of receiving mastectomy over BCT, compared to White women (OR [95% CI], 1.35 [1.30-1.39]; p<0.001). In contrast, Black women were less likely than White women to receive mastectomy (0.86 [0.84-0.87]; p<0.001). Upon disaggregation, Chinese, Japanese, Filipino, Korean, Vietnamese, and Asian Indian & Pakistani women were more likely to receive mastectomy over BCT compared to White women (p<0.001 for all). Treatment at academic (1.30 [1.27-1.32]), integrated (1.24 [1.21-1.27]), and comprehensive community cancer centers (1.15 [1.13-1.17]) were all associated with greater odds of mastectomy compared to treatment at community cancer programs (all p<0.001). Greater distance from treatment facility (≥50 mi. vs. 0 to <10 mi. [reference], OR 1.50 [1.47-1.53]) and cT2 disease (1.85 [1.82-1.87]) were also associated with greater odds of receiving mastectomy (all p<0.001). In this evaluation of women with early-stage breast cancer, women from several AANHPI groups were more likely to receive mastectomy (as opposed to BCT) compared to White women. While sociocultural preferences, differences in access to and interest in reconstruction, as well as prevalent tumor-to-breast ratios may partially explain the disparities, collectively our data suggest an ongoing need for greater patient involvement in shared-decision making, particularly in vulnerable and understudied Asian populations.

Suicide Among Asian American, Native Hawaiian, and Pacific Islander Veterans: Rates and Methods, 2005–2019

Knowledge of suicide rates and methods among Asian American, Native Hawaiian, and Pacific Islander (AANHPI) Veterans remains sparse. Age- and sex-specific suicide rates, methods, and trends were examined among AANHPI Veterans and were compared with findings reported for all Veterans. For this population-based retrospective cohort study, average annual suicide rates (2005-2019) were computed in 2023 using population (U.S. Veterans Eligibility Trends and Statistics) and mortality (National Death Index [NDI]) data. The cohort included 416,454 AANHPI Veterans (356,146 males, 60,229 females) separated from military service and alive as of 1/1/2005. Suicide was determined from NDI underlying cause-of-death ICD-10 codes. The age-adjusted average annual suicide rate among AANHPI Veterans increased 36.85% from 2005-2009 to 2015-2019 (2015-2019: 30.97/100,000). Relative to other ages, 2015-2019 suicide rates were highest among AANHPI Veterans 18-34 (overall: 53.52/100,000; males: 58.82/100,000; females: 32.24/100,000) and exceeded those of similarly aged Veterans in the overall Veteran population (overall: 44.71/100,000; males: 50.59/100,000; females: 19.24/100,000). The sex difference in suicide rates was lower among AANHPI Veterans than in Veterans overall (relative risk [males to females]=1.65 and 2.33, among those 18-54). Firearms were used less and suffocation more among AANHPI Veterans, relative to Veterans overall. Suicide among AANHPI Veterans is an increasing public health concern, with younger males and females at particularly elevated risk. Lethal means safety strategies for AANHPI Veterans should consider distinctions in suicide methods compared to the overall Veteran population. Research is warranted to understand the lower magnitude sex difference in suicide rates among AANHPI Veterans.

Experiences with Racism Among Asian American Medical Students

Asian American physicians have experienced a dual pandemic of racism and COVID-19 since 2020; understanding how racism has affected the learning environment of Asian American medical students is necessary to inform strategies to promoting a more inclusive medical school environment and a diverse and inclusive workforce. While prior research has explored the influence of anti-Asian racism on the experiences of Asian American health care workers, to our knowledge there are no studies investigating how racism has impacted the training experiences of Asian American medical students. To characterize how Asian American medical students have experienced anti-Asian racism in a medical school learning environment. This qualitative study included online video interviews of Asian American medical students performed between July 29, 2021, and August 22, 2022. Eligible participants were recruited through the Asian Pacific American Medical Students Association and snowball sampling, and the sample represented a disaggregated population of Asian Americans and all 4 medical school years. The medical school experiences of Asian American medical students. Among 25 participants, Asian ethnicities included 8 Chinese American (32%), 5 Korean American (20%), 5 Indian American (20%), 3 Vietnamese American (12%), 2 Filipino American (8%), and 1 (4%) each Nepalese, Pakistani, and Desi American; 16 (64%) were female. Participants described 5 major themes concerning their experience with discrimination: (1) invisibility as racial aggression (eg, "It took them the whole first year to be able to tell me apart from the other Asian guy"); (2) visibility and racial aggression ("It transitioned from these series of microaggressions that every Asian person felt to actual aggression"); (3) absence of the Asian American experience in medical school ("They're not going to mention Asian Americans at all"); (4) ignored while seeking support ("I don't know what it means to have this part of my identity supported"); and (5) envisioning the future. In this qualitative study, Asian American medical students reported feeling invisible within medical school while a target of anti-Asian racism. Addressing these unique challenges related to anti-Asian racism is necessary to promote a more inclusive medical school learning environment.

Residual radiation risk disparities across sex and race or ethnic groups for lifetime never-smokers on lunar missions

Missions to the Earth's moon are of scientific and societal interest, however pose the problem of risks of late effects for returning crew persons, most importantly cancer and circulatory diseases. In this paper, we discuss NSCR-2022 model risk estimates for lunar missions for US racial and ethnic groups comparing never-smokers (NS) to US averages for each group and sex. We show that differences within groups between men and women are reduced for NS compared to the average population. Race and ethnic group dependent cancer and circulatory disease risks are reduced by 10% to 40% for NS with the largest decrease for Whites. Circulatory disease risks are changed by less than 10% for NS and in several cases modestly increased due to increased lifespan for NS. Asian-Pacific Islanders (API) and Hispanics NS are at lower risk compared to Whites and Blacks. Differences between groups are narrowed for NS compared to predictions for average populations, however disparities remain especially for Blacks and to a lesser extent Whites compared to API or Hispanic NS groups.

Chronic Hypertension in Pregnancy and Racial-Ethnic Disparities in Complications.

To evaluate whether there are individual- and population-level associations between chronic hypertension and pregnancy complications, and to assess differences across seven racial-ethnic groups. This population-based study used linked vital statistics and hospitalization discharge data from all live and stillbirths in California (2008-2018), Michigan (2008-2020), Oregon (2008-2020), Pennsylvania (2008-2014), and South Carolina (2008-2020). We used multivariable log-binomial regression models to estimate risk ratios (RRs) and population attributable risk (PAR) percentages with 95% CIs for associations between chronic hypertension and several obstetric and neonatal outcomes, selected based on prior evidence and pathologic pathways. We adjusted models for demographic factors (race and ethnicity, payment method, educational attainment), age, body mass index, obstetric history, delivery year, and state, and conducted analyses stratified across seven racial-ethnic groups. The study included 7,955,713 pregnancies, of which 168,972 (2.1%) were complicated by chronic hypertension. Chronic hypertension was associated with several adverse obstetric and neonatal outcomes, with the largest adjusted PAR percentages observed for preeclampsia with severe features or eclampsia (22.4; 95% CI 22.2-22.6), acute renal failure (13.6; 95% CI 12.6-14.6), and pulmonary edema (10.7; 95% CI 8.9-12.6). Estimated RRs overall were similar across racial-ethnic groups, but PAR percentages varied. The adjusted PAR percentages (95% CI) for severe maternal morbidity-a widely used composite of acute severe events-for people who were American Indian or Alaska Native, Asian, Black, Latino, Native Hawaiian or Other Pacific Islander, White, and Multiracial or Other were 5.0 (1.1-8.8), 3.7 (3.0-4.3), 9.0 (8.2-9.8), 3.9 (3.6-4.3), 11.6 (6.4-16.5), 3.2 (2.9-3.5), and 5.5 (4.2-6.9), respectively. Chronic hypertension accounts for a substantial fraction of obstetric and neonatal morbidity and contributes to higher complication rates, particularly for people who are Black or Native Hawaiian or Other Pacific Islander.

Roots, Leaves, and Flowers: A Narrative Review of Herbs and Botanicals Used for Self-Managed Abortion in Asia and the Pacific.

Abortion has existed throughout history, often outside of formal health care systems. This type of care, now called self-managed abortion, has historically been achieved in part through botanicals and traditional medicines. Their use continues into the modern day, especially in Asia, Hawai'i, and other Pacific Islands, where indigenous medicine traditions practice alongside allopathic medicine. Many of these botanicals, such as papaya leaves, hibiscus flowers, and young kī, and traditional medicines, such as tianhuafen, yuanhua, and Shenghua Decoction, have undergone scientific and clinical investigation of their potential abortifacient and antifertility action. The incidence of self-managed abortion with such abortifacients in countries with severe abortion restrictions are only estimates, leading to the possibility that legal rulings and societal pressures may cause underreporting. The Asian American, Native Hawaiian, and Pacific Islander communities in the United States also suffer from a lack of abortion access in addition to unique health disparities and barriers to reproductive health care. As difficulties in abortion access increases due to the Supreme Court decision in Dobbs v. Jackson Women's Health Organization, some may seek or even prefer self-managed abortion through traditional methods that have been passed down in their communities. Midwives and other health care providers may then be contacted during this process. This narrative review provides an overview of the literature on the use of botanicals, herbs, and traditional medicines used for self-managed abortion, specifically in Asia, Hawai‧i, and other Pacific Islands. Their implications for practice for providers in the United States and further opportunities for research are also presented.

Acral lentiginous melanoma incidence by sex, race, ethnicity, and stage in the United States, 2010–2019

IntroductionAcral lentiginous melanoma (ALM) is a rare type of melanoma associated with delayed diagnosis and poor survival rates. This study examines ALM incidence rates in comparison to all other melanoma types. MethodsWe used data from the Centers for Disease Control and Prevention's National Program of Cancer Registries and the National Cancer Institute's Surveillance, Epidemiology, and End Results Program, which together cover 99% of the US population. We calculated age-adjusted rates and rate ratios for ALM and all other malignant melanomas by sex, race and ethnicity, stage, and year of diagnosis (2010–2019). ResultsALM incidence rates were significantly lower among non-Hispanic Black persons (1.8 per 1,000,000); non-Hispanic Asian/Pacific Islander (API) persons (1.7 per 1,000,000); and Hispanic Black, American Indian/Alaska Native (AI/AN), and API persons (1.5 per 1,000,000) compared to non-Hispanic White persons (2.3 per 1,000,000). Rates were significantly higher among Hispanic White persons (2.8 per 1,000,000) compared to non-Hispanic White persons. For all other melanoma types, incidence rates were significantly higher among non-Hispanic White persons compared to persons in each of the other racial and ethnic categories. The percentage of melanomas that were ALM ranged from 0.8% among non-Hispanic White persons to 19.1% among Hispanic Black, AI/AN, and API persons. ConclusionThese findings suggest that awareness of the potential for ALM in patients of all races and ethnicities could be balanced with an understanding of the rarity of the disease and the potential for the development of other melanoma types in racial and ethnic minority groups.

Abstract P151: Examining The Inclusion And Analysis Of Race-Sex Groups In Primary Hypertension Studies Conducted In The US: A Comprehensive Review

Background: Patients from underrepresented backgrounds, including women of color, in the US have a higher prevalence of hypertension and may experience worse outcomes. Although there has been increased awareness regarding the importance of representation in cardiovascular studies, a substantial disparity in study populations persists. Objective: This study aimed to assess the inclusion and reporting of race-sex groups in studies conducted in the US between 2012-2022 that focused on primary hypertension as an outcome. Methods: We conducted a systematic search using Covidence to extract original peer-reviewed studies from PubMed and Embase. After removing duplicates, two investigators performed a title and abstract review to select studies. The studies that met the criteria underwent full-text screening and were downloaded to a shared spreadsheet. Additionally, studies with analyses by race-sex groups were identified and reviewed for theme extraction. Results: Out of 157 studies on hypertension, 20 studies (12.7%) reported results stratified by race-sex. Within these studies, women accounted for an average of 56.5 ± 14.7% of the overall study population, and the primary focus was on the prevalence of hypertension (N=17). However, some reported hypertension control (N=6), treatment (N=5), and trends (N=5). While all these studies included Non-Hispanic (NH) White and NH Black subgroups, only nine (45%) included Hispanic/Latinx, six (30%) included Asian American and Pacific Islander, and none included Native American/American Indian. Among the studies that reported demographic breakdowns (N=14), NH White individuals consisted of more than 50% of the study population in nine studies, whereas NH Black individuals comprised ≥20% of the study population in six studies. Conclusion: There is still a lack of studies on primary hypertension in the US that include and analyze - but most importantly - report their results by race-sex groups. Additionally, a significant gap persists in the inclusion of individuals from underrepresented backgrounds, especially Asian American and Pacific Islanders and Native American/American Indians. Future studies could benefit from incorporating race-sex analyses and results to address these disparities.

Marginal structural models for estimating the longitudinal effects of community violence exposure on youths' internalizing and externalizing symptoms.

Longitudinal observational data pose a challenge for causal inference when the exposure of interest varies over time alongside time-dependent confounders, which often occurs in trauma research. We describe marginal structural models (MSMs) using inverse probability weighting as a useful solution under several assumptions that are well-suited to estimating causal effects in trauma research. We illustrate the application of MSMs by estimating the joint effects of community violence exposure across time on youths' internalizing and externalizing symptoms. Our sample included 4,327 youth (50% female, 50% male; 1.4% Asian American or Pacific Islander, 34.7% Black, 46.9% Hispanic, .8% Native American, 14.3%, White, 1.5%, Other race/ethnicity; Mage at baseline = 8.62, range = 3-15) from the Project on Human Development in Chicago Neighborhoods. Wave 3 internalizing symptoms increased linearly with increases in Wave 2 and Wave 3 community violence exposure, whereas effects on externalizing symptoms were quadratic for Wave 2 community violence exposure and linear for Wave 3. These results fail to provide support for the desensitization model of community violence exposure. MSMs are a useful tool for researchers who rely on longitudinal observational data to estimate causal effects of time-varying exposures, as is often the case in the study of psychological trauma.
