BACKGROUND: We sought to identify characteristics of metastatic breast cancer (MBC) patients who may benefit most from primary tumor resection. METHODS: Recursive partitioning analysis (RPA) was used to categorize non-surgical patients with de novo MBC in the NCDB (2010–2015) into 3 groups (I/II/III) based on 3-year overall survival (OS). After bootstrapping (BS), group-level profiles were applied, and the association of surgery with OS was estimated using Cox proportional hazards models. RESULTS: All patients benefitted from surgery (median OS, surgery vs no surgery): 72.7 vs 42.9 months, 47.3 vs 30.4 months, 23.8 vs 14.4 months (all p

Since the 1980s, the mortality rate from breast cancer in the United States has dropped almost 40%. The quality of life and survival gains from early detection and improved treatment have not been shared equally by all ethnic groups, however. Many factors, including social determinants of health, unequal access to screening and oncologic care, and differences in incidence, tumor biology, and risk factors, have contributed to these unequal breast cancer outcomes. As breast radiologists approach their own patients, they must be aware that minority women are disproportionately affected by breast cancer at earlier ages and that non-Hispanic Black and Hispanic women are impacted by greater severity of disease than non-Hispanic White women. Guidelines that do not include women younger than 50 and/or have longer intervals between examinations could have a disproportionately negative impact on minority women. In addition, the COVID-19 pandemic could worsen existing disparities in breast cancer mortality. Increased awareness and targeted efforts to identify and mitigate all of the underlying causes of breast cancer disparities will be necessary to realize the maximum benefit of screening, diagnosis, and treatment and to optimize quality of life and mortality gains for all women. Breast radiologists, as leaders in breast cancer care, have the opportunity to address and reduce some of these disparities for their patients and communities.

BACKGROUND. Contralateral axillary nodal metastases (CAM) is classified as stage IV disease, although many centers treat CAM with curative intent. We hypothesized that patients with CAM, treated with multimodality therapy, would have improved overall survival (OS) versus patients with distant metastatic disease (M1) and similar OS to those with locally advanced breast cancer (LABC). METHODS. Using the NCDB (2004–2016), we categorized adult patients with node-positive breast cancer into three study groups: LABC, CAM, and M1. Kaplan-Meier curves were used to visualize the unadjusted OS. Cox proportional hazards models were used to estimate the association of study group with OS. RESULTS. A total of 94,487 patients were identified: 122 with CAM, 12,325 with LABC, and 82,040 with M1 (median follow-up 63.6 months). LABC and CAM patients had similar histology and rates of chemotherapy and endocrine therapy receipt. However, the CAM group had significantly larger tumors, more estrogen-receptor expression, higher T-stage, and more mastectomies than the LABC group. Compared with M1 patients, CAM patients were more likely to have grade 3 and cT4 tumors. Patients with CAM and LABC had similar 5-year unadjusted OS and significantly improved OS vs M1 patients. After adjustment, LABC and CAM patients continued to have similar OS and better OS vs M1 patients. CONCLUSIONS. CAM patients who receive multi-modal therapy with curative intent may have OS more comparable to LABC patients than M1 patients. Out data support a reevaluation of whether CAM should remain classified as M1, as N3 may better reflect disease prognosis and treatment goals.

The Society of Surgical Oncology is committed to reducing health disparities adversely affecting sexual and gender minorities. Transgender persons represent a socially disadvantaged group who frequently experience discrimination and receive disparate care, resulting in suboptimal cancer outcomes. The rate of breast cancer development in transgender individuals differs from rates observed in their cisgender counterparts, however there is little evidence to quantify these differences and guide evidence-based screening and prevention. There is no consensus for breast cancer screening guidelines in transgender patients. In this review, we discuss barriers to equitable breast cancer care, risk factors for breast cancer development, and existing data to support breast cancer screening in transgender men and women.

BACKGROUND. Although metastatic breast cancer (MBC) remains incurable, advances in therapies have improved survival. Using a contemporary dataset of de novo MBC patients, we explore how overall (OS) and cancer-specific survival (CSS) changed over time. METHODS. All patients with de novo MBC from 1988 to 2016 were selected from Surveillance, Epidemiology, and End Results (SEER) 18. Unadjusted OS and CSS were estimated by Kaplan–Meier method and stratified by disease characteristics. Cox proportional hazards models determined factors associated with survival. RESULTS. 47,034 patients were included, with median OS of 25 months and CSS of 27 months. Survival steadily improved over time (1988: 1-year OS 62%, CSS 65%; 2015: 1-year OS 72%, CSS 74%). Patients with triple-negative breast cancer (TNBC) had the worst prognosis and were most likely to die from MBC [versus human epidermal growth factor receptor 2 (HER2)+ and hormone receptor (HR)+/HER2−]. Those with ≥ 4 sites of metastatic disease were also more likely to die from MBC with nearly identical OS and CSS (5-year OS 9%, CSS 9%), when compared with those with 1 site (5-year OS 31%, CSS 35%). After adjustment, improved CSS was associated with bone-only disease [hazard ratio (HR) 0.88, 95% confidence interval (CI) 0.83–0.94], while TNBC (versus HER2+: HR 3.12, 95% CI 2.89–3.36) and > 3 sites of metastatic disease (versus 1 site: HR 3.24, 95% CI 2.68–3.91) were associated with worse CSS (all p < 0.001). CONCLUSIONS. Accurate prognostic estimates are essential for patient care. As treatments for patients with MBC have expanded, OS and CSS have improved, and more patients, particularly with limited distant disease or favorable tumor subtypes, are also dying from non-MBC causes.

INTRODUCTION: We compared characteristics and outcomes by treatment sequence among patients with metaplastic breast cancer (MBC), an aggressive subtype. METHODS: Women ≥18 years old with newly diagnosed Stage I-III MBC from 2003 to 2018 who received any treatment in our health system were identified. Unadjusted overall survival (OS) was estimated with the Kaplan-Meier method; the log-rank test was used to compare survival differences between recipients of neoadjuvant (NACT) and adjuvant chemotherapy (ACT). RESULTS: Of the 91 MBC patients identified, 60 received chemotherapy. NACT recipients (n = 20, median age 46.5 y) were younger than ACT recipients (n = 40, median age 60.5 y, p < 0.001) but similar with regards to race and radiation receipt. There was no significant OS difference between NACT and ACT recipients (log-rank p = 0.15), which remained true when patients were stratified by age (≥50 y vs < 50 y). CONCLUSIONS: Among MBC patients, NACT recipients were younger than ACT recipients, but there was no survival difference by treatment sequence.

BACKGROUND: Women of color with breast cancer are less likely to undergo post-mastectomy reconstruction compared with White women, but it is unclear whether their perioperative outcomes are worse. The goal of this study was to investigate differences in preoperative comorbidities and postoperative complications by race/ethnicity among women with breast cancer undergoing postmastectomy reconstruction. STUDY DESIGN: Data were collected from the National Inpatient Sample database of the Healthcare Cost and Utilization Project from 2012 to 2016. Patient demographics, types of reconstruction, comorbid conditions, Charlson-Deyo Combined Comorbidity (CDCC) scores, length of stay (LOS), and perioperative complications were abstracted. Multivariate linear and logistic regression were performed to model LOS and likelihood of postoperative complications, respectively. RESULTS: Compared with White women (n = 19,730), Black women (n = 3,201) underwent autologous reconstruction more frequently (40.7% vs 28.3%), had more perioperative comorbidities (eg diabetes: 12.9% vs 5.8%), higher CDCC scores (% CDCC ≥ 4: 5.5% vs 2.7%), and longer LOS (median 3 vs 2 days, all p < 0.001). Being Black (vs white: +0.13 adjusted days, 95% CI 0.06 to 0.19) was also associated with longer LOS and an increased likelihood of surgical complications (vs White: odds ratio 1.24, 95% CI 1.09 to 1.42, both p < 0.01), but this association did not persist when outcomes were limited to microsurgical complications. CONCLUSION: Disparities in postmastectomy breast reconstruction between Black and White women extend beyond access to care and include perioperative factors and outcomes. These findings suggest an important opportunity to mitigate inequities in reconstruction through perioperative health optimization and improved access to and co-management with primary care.

PURPOSE: Time to surgery (TTS) is a potentially modifiable factor associated with survival after breast cancer diagnosis and can serve as a proxy for quality of oncologic care coordination. We sought to determine whether factors associated with delays in TTS vary between patients who receive neoadjuvant systemic therapy (NST) vs upfront surgery and whether the impact of these delays on overall survival (OS) varies with treatment sequence. METHODS: Women ≥18 years old with Stage I-III breast cancer were identified in the National Cancer Database (2004–2014). Multivariate linear regression stratified by treatment sequence (upfront-surgery vs NST [neoadjuvant chemotherapy {NAC}, neoadjuvant endocrine therapy {NAE}, or both {NACE}]) was used to identify factors associated with TTS. Cox proportional hazards models were used to estimate the effect of TTS on overall survival (OS). RESULTS: Of 693,469 patients, 14.8% (n=102,326) received NST (NAC n=85,143, NAE n=10,004, NACE n=7179). Non-White race/ethnicity, no or government-issued insurance, more extensive surgery (i.e., mastectomy and contralateral prophylactic mastectomy vs breast-conserving surgery), and post-mastectomy reconstruction were associated with significantly longer adjusted TTS for NAC and upfront-surgery recipients, but only upfront-surgery patients had progressively worse OS with increasing TTS (>180 vs ≤30 days: HR=1.31, all p

BACKGROUND: We examined whether the National Comprehensive Cancer Network distress thermometer (DT), a patient-reported outcome measure, could be used to identify levels and causes of distress associated with racial/ethnic disparities in time to care among patients with breast cancer. METHODS: We identified women aged ≥18 years with stage O-IV breast cancer who were diagnosed in a single health system between January 2014 and July 2016. The baseline visit was defined as the first postdiagnosis, pretreatment clinical evaluation. Zero-inflated negative binomial (ZINB) regression (modeling non-zero DT scores and DT scores = 0) and logistic regression (modeling DT score ≥ 4, threshold for social services referral) were used to examine associations between baseline score (0 = none to 10 = extreme) and types of stressors (emotional, familial, practical, physical, spiritual) after adjustment for race/ethnicity and other characteristics. Linear regression with log transformation was used to identify predictors of time to evaluation and time to treatment. RESULTS: A total of 1029 women were included (median baseline DT score = 4). Emotional, physical, and practical stressors were associated with distress in both the ZINB and logistic models (all P < .05). Black patients (n = 258) were more likely to report no distress than Whites (n = 675; ZINB zero model odds ratio, 2.72; 95% CI, 1.68-4.40; P < .001) despite reporting a similar number of stressors (P = .07). Higher DT scores were associated with shorter time to evaluation and time to treatment while being Black and having physical or practical stressors were associated with delays in both (all P < .05). CONCLUSIONS: Patient-reported stressors predicted delays in time to care, but patient-reported levels of distress did not, with Black patients having delayed time to care despite reporting low levels of distress. We describe anticipatory, culturally responsive strategies for using patient-reported outcomes to address observed disparities.

BACKGROUND: Elderly women with clinically node-positive (cN+) breast cancer (BC) often have comorbidities that limit life expectancy and complicate treatment. We sought to determine whether the number of lymph nodes (LNs) retrieved among older women with node-positive breast cancer was associated with overall survival (OS). METHODS: Using the National Cancer Database (2010–2015), women 70–90y with cN+ BC and ≥1 LN removed were categorized by treatment sequence: upfront surgery or neoadjuvant chemotherapy (NAC). Multivariable Cox proportional hazards models with restricted cubic splines characterized the functional association of LN retrieval with OS; threshold values of LN retrieval were estimated. Cox proportional hazards models were used to estimate the association of LN retrieval groups with OS. RESULTS: In the upfront surgery cohort, a non-linear association was identified between LNs retrieved and OS. In the NAC cohort, no association was identified. For the upfront surgery cohort, the optimal threshold value of LN retrieval was 21 LN (90% CI 18–23). Based on this estimate, LN retrieval groups were created: 23 LNs. After adjustment, retrieval of

OBJECTIVE To determine the role of race and gender in the career experience of Black/AA academic surgeons and to quantify the prevalence of experience with racial and gender bias stratified by gender. SUMMARY OF BACKGROUND DATA Compared to their male counterparts, Black/African American women remain significantly underrepresented among senior surgical faculty and department leadership. The impact of racial and gender bias on the academic and professional trajectory of Black/AA women surgeons has not been well-studied. METHODS A cross-sectional survey regarding demographics, employment, and perceived barriers to career advancement was distributed via email to faculty surgeon members of the Society of Black American Surgeons (SBAS) in September 2019. RESULTS Of 181 faculty members, 53 responded (29%), including 31 women (58%) and 22 men (42%). Academic positions as a first job were common (men 95% vs women 77%, P = 0.06). Men were more likely to attain the rank of full professor (men 41% vs women 7%, P = 0.01). Reports of racial bias in the workplace were similar (women 84% vs men 86%, not significant); however, reports of gender bias (women 97% vs men 27%, P < 0.001) and perception of salary inequities (women 89% vs 63%, P = 0.02) were more common among women. CONCLUSIONS AND RELEVANCE Despite efforts to increase diversity, high rates of racial bias persist in the workplace. Black/AA women also report experiencing a high rate of gender bias and challenges in academic promotion.

OBJECTIVE: We aim to identify prognostic groups within a de novo metastatic cohort, incorporating both anatomic and biologic factors. BACKGROUND: Staging for breast cancer now includes anatomic and biologic factors, although the guidelines for stage IV disease do not account for how these factors may influence outcomes. METHODS: Adults with de novo metastatic breast cancer were selected from the National Cancer DataBase (2010–2013). Recursive partitioning analysis was used to group patients with similar overall survival (OS) based on clinical T/N stage, tumor grade, ER, PR, HER2, number of metastatic sites, and presence of bone-only metastases. Categories were created by amalgamating homogeneous groups based on 3-year OS rates (stage IVA: >50%, stage IVB: 30%–50%, stage IVC: 1) as the first stratification point, and ER status as the second stratification point for both resulting groups. Additional divisions were made based on HER2 status, PR status, cT stage, tumor grade, and presence of bone-only metastases. After bootstrapping, significant differences in 3-year OS were noted between the 3 groups [stage IVB vs IVA: HR 1.58 (95% confidence interval 1.50–1.67), stage IVC vs IVA: HR 3.54 (95% confidence interval 3.33–3.77)]. CONCLUSIONS: Both anatomic and biologic factors yielded reliable and reproducible prognostic estimates among patients with metastatic disease. These findings support formal stratification of de novo stage IV breast cancer into 3 distinct prognosis groups.

Objective To determine the representation of Black/AA women surgeons in academic medicine among U.S. medical school faculty and to assess the number of NIH grants awarded to Black/AA women surgeon-scientists over the past 2 decades. Summary of background data Despite increasing ethnic/racial and sex diversity in U.S. medical schools and residencies, Black/AA women have historically been underrepresented in academic surgery. Methods A retrospective review of the Association of American Medical Colleges 2017 Faculty Roster was performed and the number of grants awarded to surgeons from the NIH (1998-2017) was obtained. Data from the Association of American Medical Colleges included the total number of medical school surgery faculty, academic rank, tenure status, and department Chair roles. Descriptive statistics were performed. Results Of the 15,671 U.S. medical school surgical faculty, 123 (0.79%) were Black/AA women surgeons with only 11 (0.54%) being tenured faculty. When stratified by academic rank, 15 (12%) Black/AA women surgeons were instructors, 73 (59%) were assistant professors, 19 (15%) were associate professors, and 10 (8%) were full professors of surgery. Of the 372 U.S. department Chairs of surgery, none were Black/AA women. Of the 9139 NIH grants awarded to academic surgeons from 1998 and 2017, 31 (0.34%) grants were awarded to fewer than 12 Black/AA women surgeons. Conclusion A significant disparity in the number of Black/AA women in academic surgery exists with few attaining promotion to the rank of professor with tenure and none ascending to the role of department Chair of surgery. Identifying and removing structural barriers to promotion, NIH grant funding, and academic advancement of Black/AA women as leaders and surgeon-scientists is needed.

Background: Meta-analyses have demonstrated that young women ≤40 (YW) derive the most benefit from chemotherapy (EBCTCG, Lancet. 1998). Oncotype DX was designed to determine the benefit of chemotherapy in women with ER+/HER2-, node-negative (LN-) breast cancer based on recurrence score (RS). TAILORx reported clinically meaningful benefits in freedom-from-distant recurrence in women Methods: Using the National Cancer Data Base (NCDB), we identified individuals age 25) RS. Age categories were classified as ≤40, 41-50, and >50. Chi-square tests or Fisher’s exact tests were used to compare categorical variables. Logistic regression was used to estimate the association of RS score and age group with adjuvant chemotherapy use, after adjustment for known covariates. Kaplan-Meier curves were used to visualize unadjusted overall survival (OS), and Cox proportional hazards models were used to estimate adjusted OS. Results: 120,051 women were identified, of whom 4,781 were ≤40 years, 24,846 were 41-50, and 90,424 were >50. By age group, 20% of YW had a high RS compared to 12% of women age 41-50 and 15% of women >50 (p50 to receive chemotherapy (p Conclusions: High RS is more common in YW (≤40) than those age 41-50 or >50, and is associated with worse OS. YW with an int or low RS are more likely to receive chemotherapy despite unclear benefit. Chemotherapy was omitted in over half of YW with RS of 16-25, highlighting the uncertainty in clinical practice which will remain until further studies inform optimal systemic treatment specific to YW. 1.

Pathologic complete response (pCR) after neoadjuvant chemotherapy (NACT) is associated with improved overall survival (OS) in patients with breast cancer, but it is unclear how post-NACT response influences radiation therapy administration in patients presenting with node-positive disease. We sought to determine whether nodal pCR is associated with likelihood of receiving nodal radiation and whether radiation therapy among patients experiencing nodal pCR is associated with improved OS.Clinical N1 (cN1) female breast cancer patients diagnosed during 2010 to 2015 who were ypN0 (ie, nodal pCR; n = 12,341) or ypN1 (ie, residual disease; n = 13,668) after NACT were identified in the National Cancer Database. Multivariate logistic regression was used to identify factors associated with receiving radiation therapy. Cox proportional hazards modeling was used to estimate the association between radiation therapy and adjusted OS.The study included 26,009 patients; 43.9% (n = 5423) of ypN0 and 55.3% (n = 7556) of ypN1 patients received nodal radiation. Rates of nodal radiation remained the same over time among ypN0 patients (trend test, P = .29) but increased among ypN1 patients from 49% in 2010 to 59% in 2015 (trend test, P.001). After adjusting for covariates, nodal pCR (vs no stage change) was associated with decreased likelihood of nodal radiation after mastectomy (∼20% decrease) and lumpectomy (∼30% decrease; both P.01). After mastectomy, nodal (vs no) radiation conferred no significant survival benefit in ypN0 patients, but it approached significance for ypN1 patients (hazard ratio [HR], 0.83; 95% confidence interval [CI], 0.69-0.99, P = .04; overall P = .11). After lumpectomy, nodal radiation was associated with improved adjusted OS for ypN0 (HR, 0.38; 95% CI, 0.22-0.66) and ypN1 patients (HR, 0.44; 95% CI, 0.30-0.66; both P.001), but this improvement was not significantly greater than that associated with breast-only radiation.ypN0 patients were less likely to receive nodal radiation than ypN1 patients were, suggesting that selective omission already occurs and, in the context of limited survival data, could potentially be appropriate for select patients.

BACKGROUND: Given presumed differences in disease severity between young (≤ 45 years) and elderly (≥ 75 years) women with breast cancer, we sought to compare tumor histopathology, stage at presentation, patterns of care, and survival at the extremes of age. METHODS: Adults with stages 0–IV breast cancer in the National Cancer Database (2004–2015) were categorized by age (18–45 years, 46–74 years, ≥ 75 years) and compared. Kaplan–Meier curves were used to visualize unadjusted overall survival (OS). A Cox proportional-hazards model was used to estimate the effect of age group, including adjustment for tumor subtype [hormone receptor [HR]+/HER2−, HER2+, triple-negative (TN)]. RESULTS: Of the 1,201,252 patients identified, 13% were ≤ 45 years and 17.5% were ≥ 75 years. Women ≤ 45 years were more likely to have higher pT/N stages and grade 3 disease compared to older patients; however, rates of de novo cM1 disease were comparable (3.7% vs 3.5%). HER2+ and TN tumors were more common in those ≤ 45 years (HER2+ : 18.6% vs 9.2%; TN: 14.9% vs 8.2%), while HR+/HER2− tumors were more likely in women ≥ 75 years (69.3% vs 51.3%) (all p < 0.001). Younger patients were more likely to undergo mastectomy vs lumpectomy (56% vs 34%), and receive chemotherapy (65.8% vs 10.2%) and radiation (56.2% vs 39.5%). After adjustment, OS was worse in older patients (older HR 2.94, CI 2.86–3.03). CONCLUSIONS: High-risk tumor subtypes and comprehensive multimodal treatment remain significantly more common among younger women (≤ 45 years) with breast cancer, yet, elderly women are similarly diagnosed with incurable de novo metastatic disease. Tailored screening and treatment strategies are critical to prevent age-related disparities in breast cancer care.

INTRODUCTION. The opioid epidemic in the United States is a public health crisis. Breast surgeons are obligated to provide good pain control for their patients after surgery but also must minimize administration of narcotics to prevent a surgical episode of care from becoming a patient’s gateway into opioid dependence. METHODS. A survey to ascertain pain management practice patterns after breast surgery was performed. A review of currently available literature that was specific to breast surgery was performed to create recommendations regarding pain management strategies. RESULTS. A total of 609 surgeons completed the survey and demonstrated significant variations in pain management practices, specifically within regards to utilization of regional anesthesia (e.g., nerve blocks), and quantity of prescribed narcotics. There is excellent data to guide the use of local and regional anesthesia. There are, however, fewer studies to guide narcotic recommendations; thus, these recommendations were guided by prevailing practice patterns. CONCLUSIONS. Pain management practices after breast surgery have significant variation and represent an opportunity to improve patient safety and quality of care. Multimodality approaches in conjunction with standardized quantities of narcotics are recommended.

PURPOSE: Inflammatory breast cancer (IBC) is an aggressive variant for which axillary lymph node dissection following neoadjuvant chemotherapy (NACT) remains standard of care. But with increasingly effective systemic therapy, it is unclear whether more limited axillary surgery may be appropriate in some IBC patients. We sought to examine whether extent of axillary lymph node (LN) surgery was associated with overall survival (OS) for IBC. METHODS: Female breast cancer patients with non-metastatic IBC (cT4d) diagnosed 2010–2014 were identified in the National Cancer Data Base. Cox proportional hazards modeling was used to estimate the association between extent of axillary surgery (≤9 vs ≥10 LNs removed) and OS after adjusting for covariates, including post-NACT nodal status (ypN0 vs ypN1–3) and radiotherapy receipt (yes/no). RESULTS: 3,471 patients were included: 597 (17.2%) had cN0 disease, 1,833 (52.8%) had cN1 disease, and 1,041 (30%) had cN2–3 disease. 49.9% of cN0 patients were confirmed to be ypN0 on post-NACT surgical pathology. Being ypN0 (vs ypN1–3) was associated with improved adjusted OS for all patients. Radiotherapy was associated with improved adjusted OS for cN1 and cN2–3 patients but not for cN0 patients. Regardless of ypN status, there was a trend towards improved adjusted OS with having ≥10 (vs ≤9) LNs removed for cN2–3 patients (HR 0.78, 95% CI 0.60–1.01, p=0.06) but not for cN0 patients (p=0.83). CONCLUSIONS: A majority of IBC patients in our study presented with node-positive disease, and for those presenting with cN2–3 disease, more extensive axillary surgery is potentially associated with improved survival. For cN0 patients, however, more extensive axillary surgery was not associated with a survival benefit, suggesting an opportunity for more personalized care.

This cohort study uses existing data on race, ethnicity, and sex among US surgical faculty members and medical students to identify changes between 2011 and 2020.

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.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.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).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.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.

Breast surgical oncology is a rapidly evolving field with significant advances shaped by practice-changing research. Three areas of ongoing controversy are (1) high rates of contralateral prophylactic mastectomy (CPM) in the United States despite uncertain benefit, (2) indications for and use of neoadjuvant chemotherapy (NACT) and endocrine therapy (NET), and (3) staging and treatment of the axilla, particularly after neoadjuvant systemic therapy. We discuss the patient populations for whom CPM may or may not be beneficial, indications for NACT and NET, and the trend toward de-escalation of locoregional axillary treatment.

Background Telehealth is an increasingly important component of health care delivery in response to the COVID-19 pandemic. However, well-documented disparities persist in the use of digital technologies. Objective This study aims to describe smartphone and internet use within a diverse sample, to assess the association of smartphone and internet use with markers of health literacy and health access, and to identify the mediating factors in these relationships. Methods Surveys were distributed to a targeted sample designed to oversample historically underserved communities from April 2017 to December 2017. Multivariate logistic regression was used to estimate the association of internet and smartphone use with outcomes describing health care access and markers of health literacy for the total cohort and after stratifying by personal history of cancer. Health care access was captured using multiple variables, including the ability to obtain medical care when needed. Markers of health literacy included self-reported confidence in obtaining health information. Results Of the 2149 participants, 1319 (61.38%) were women, 655 (30.48%) were non-Hispanic White, and 666 (30.99%) were non-Hispanic Black. The median age was 51 years (IQR 38-65). Most respondents reported using the internet (1921/2149, 89.39%) and owning a smartphone (1800/2149, 83.76%). Compared with the respondents with smartphone or internet access, those without smartphone or internet access were more likely to report that a doctor was their most recent source of health information (344/1800, 19.11% vs 116/349, 33.2% for smartphone and 380/1921, 19.78% vs 80/228, 35.1% for internet, respectively; both P Conclusions We describe widespread use of digital technologies in a community-based cohort, although disparities persist. In this cohort, smartphone ownership was significantly associated with ability to obtain needed medical care, suggesting that the use of smartphone technology may play a role in increasing health care access. Similarly, major illnesses such as cancer have the potential to amplify health engagement. Finally, special emphasis must be placed on reaching patient populations with limited digital access, so these patients are not further disadvantaged in the new age of telehealth.

Members of the Translational Breast Cancer Research Consortium conducted an expert-driven literature review to identify a list of domains and to evaluate potential measures of these domains for inclusion in a list of preferred measures. Measures were included if they were easily available, free of charge, and had acceptable psychometrics based on published peer-reviewed analyses. A total of 22 domains and 52 measures were identified during the selection process. Taken together, these measures form a reliable and validated list of measurement tools that are easily available and used in multiple cancer trials to assess patient-reported outcomes in relevant patients.

Background We aim to determine clinical and pathological stage discordance rates and to evaluate factors associated with discordance. Methods Adults with clinical stages I-III breast cancer were identified from the National Cancer Data Base. Concordance was defined as cTN = pTN (discordance: cTN≠pTN). Multivariate logistic regression was used to identify factors associated with discordance. Results Comparing clinical and pathological stage, 23.1% were downstaged and 8.7% were upstaged. After adjustment, factors associated with downstaging (vs concordance) included grade 3 (OR 10.56, vs grade 1) and HER2-negative (OR 3.79). Factors associated with upstaging (vs concordance) were grade 3 (OR 10.56, vs grade 1), HER2-negative (OR 1.25), and lobular histology (OR 2.47, vs ductal). ER-negative status was associated with stage concordance (vs downstaged or upstaged, OR 0.52 and 0.87). Conclusions Among breast cancer patients, nearly one-third exhibit clinical-pathological stage discordance. This high likelihood of discordance is important to consider for counseling and treatment planning.

Neoadjuvant chemotherapy (NACT) is often recommended for patients with node-positive invasive lobular carcinoma (ILC) despite unclear benefit in this largely hormone receptor-positive (HR+) group. We sought to compare overall survival (OS) between patients with node-positive ILC who received neoadjuvant endocrine therapy (NET) and those who received NACT. Women with cT1–4c, cN1–3 HR+ ILC in the National Cancer Data Base (2004–2014) who underwent surgery following neoadjuvant therapy were identified. Kaplan–Meier curves and Cox proportional hazards modeling were used to estimate unadjusted and adjusted overall survival (OS), respectively. Of the 5942 patients in the cohort, 855 received NET and 5087 received NACT. NET recipients were older (70 vs. 54 years) and had more comorbidities (Charlson–Deyo score ≥ 1: 21.1% vs. 11.5%), lower cT classification (cT3–4: 44.2% vs. 51.0%), lower rates of mastectomy (72.5% vs. 82.2%), lower rates of pathologic complete response (0% vs. 2.5%), and lower rates of postlumpectomy (73.2% vs. 91.0%) and postmastectomy (60.0% vs. 80.8%) radiation versus NACT recipients (all p

Background More than 20% of patients undergoing initial breast-conserving surgery (BCS) for cancer require reoperation. To address this concern, the American Society of Breast Surgeons (ASBrS) endorsed 10 processes of care (tools) in 2015 to be considered by surgeons to de-escalate reoperations. In a planned follow-up, we sought to determine which tools were associated with fewer reoperations. Methods A cohort of ASBrS member surgeons prospectively entered data into the ASBrS Mastery® registry on consecutive patients undergoing BCS in 2017. The association between tools and reoperations was estimated via multivariate and hierarchical ranking analyses. Results Seventy-one surgeons reported reoperations in 486 (12.3%) of 3954 cases (mean 12.7% [standard deviation (SD) 7.7%], median 11.5% [range 0–32%]). There was an eightfold difference between surgeons in the 10th and 90th percentile performance groups. Actionable factors associated with fewer reoperations included routine planned cavity side-wall shaves, surgeon use of ultrasound (US), neoadjuvant chemotherapy, intra-operative pathologic margin assessment, and use of a pre-operative diagnostic imaging modality beyond conventional 2D mammography. For patients with invasive cancer, ≥ 24% of those who underwent reexcision did so for reported margins of

BACKGROUND. Breast surgery carries a low risk of postoperative mortality. For older patients with multiple comorbidities, even low-risk procedures can confer some increased perioperative risk. We sought to identify factors associated with postoperative mortality in breast cancer patients ≥70 years to create a nomogram for predicting risk of death within 90 days. METHODS. Patients diagnosed with nonmetastatic invasive breast cancer (2010–2016) were selected from the National Cancer Database. Unadjusted OS was estimated using the Kaplan–Meier method. Multivariate logistic regression was used to estimate the association of age and surgery with 90-day mortality and to build a predictive nomogram. RESULTS. Among surgical patients ≥70 years, unadjusted 90-day mortality increased with increasing age (70–74 = 0.4% vs. ≥85 = 1.6%), comorbidity score (0 = 0.5% vs. ≥3 = 2.7%), and disease stage (I = 0.4% vs. III = 2.7%; all p < 0.001). After adjustment, death within 90 days of surgery was associated with higher age (≥85 vs. 70–74: odds ratio [OR] 3.16, 95% confidence interval [CI] 2.74–3.65), comorbidity score (≥3 vs. 0: OR 4.79, 95% CI 3.89–5.89), and disease stage (III vs. I: OR 4.30, 95% CI 3.69–5.00). Based on these findings, seven variables (age, gender, comorbidity score, facility type, facility location, clinical stage, and surgery type) were selected to build a nomogram; estimates of risk of death within 90 days ranged from 30%. CONCLUSIONS. Breast operations remain relatively low-risk procedures for older patients with breast cancer, but select factors can be used to estimate the risk of postoperative mortality to guide surgical decision-making among older women.

Background The North Carolina Breast and Cervical Cancer Control Program (NC BCCCP) provides breast cancer screening services to underserved women to mitigate disparities in access to care. The authors sought to characterize this understudied population. Methods Women 21 years old or older who underwent their first breast cancer screen through NC BCCCP from 2008 to 2018 were included. Demographic factors associated with the timeline of care and odds of a breast cancer diagnosis were identified with negative binomial and logistic regression, respectively. Results Of the 88,893 women identified, 45.5% were non-Hispanic (NH) White, 30.9% were NH Black, 19.6% were Hispanic, 1.7% were American Indian, and 1.1% were Asian. Breast cancer was diagnosed in 2.5% of the women (n = 2255). Hispanic women were the least likely to be diagnosed with breast cancer (odds ratio vs NH White women, 0.40; 95% confidence interval [CI], 0.34-0.47). Among patients with breast pathology, the median time to diagnosis was 19 days (interquartile range [IQR], 10-33 days), and the time to treatment was 33 days (IQR, 19-54 days). After adjustments, a longer time to diagnosis was significantly associated with age (incidence rate ratio [IRR], 1.01; 95% CI, 1.01-1.02) and being NH Black (vs NH White; IRR, 1.17; 95% CI, 1.06-1.29). A longer time to treatment was significantly associated with age (IRR, 1.01; 95% CI, 1.01-1.01), being NH Black (vs NH White; IRR, 1.20; 95% CI, 1.10-1.31), and being Hispanic (vs NH White; IRR, 1.22; 95% CI, 1.05-1.41). Conclusions NC BCCCP participants with breast cancer received treatment within approximately 1 month of presentation, and this finding aligns with quality care benchmarks. Nevertheless, racial/ethnic disparities in timeliness of care persist, and this suggests opportunities for improvement. Lay summary This review of approximately 90,000 participants in a breast cancer screening program for uninsured and underinsured women highlights the importance of safety net programs in providing timely care to underserved patients. The authors found that the North Carolina Breast and Cervical Cancer Control Program met timeliness benchmarks from the Centers for Disease Control and Prevention across all racial/ethnic groups. However, non-Hispanic Black women experienced relative delays in the time to diagnosis, and both non-Hispanic Black women and Hispanic women experienced relative delays in the time to treatment. These findings demonstrate how racial/ethnic disparities in the timeliness of care can persist even within a program intended to reduce barriers to access.

PURPOSE: We sought to examine tumor subtype, stage at diagnosis, time to surgery (TTS), and overall survival (OS) among Hispanic patients of different races and among Hispanic and non-Hispanic (NH) women of the same race. METHODS: Women 18 years of age or older who had been diagnosed with stage 0-IV breast cancer and who had undergone lumpectomy or mastectomy were identified in the National Cancer Database (2004-2014). Tumor subtype and stage at diagnosis were compared by race/ethnicity. Multivariable linear regression and Cox proportional hazards modeling were used to estimate associations between race/ethnicity and adjusted TTS and OS, respectively. RESULTS: A total of 44,374 Hispanic (American Indian [AI]: 79 [0.2%]; Black: 1,011 [2.3%]; White: 41,126 [92.7%]; Other: 2,158 [4.9%]) and 858,634 NH women (AI: 2,319 [0.3%]; Black: 97,206 [11.3%]; White: 727,270 [84.7%]; Other: 31,839 [3.7%]) were included. Hispanic Black women had lower rates of triple-negative disease (16.2%) than did NH Black women (23.5%) but higher rates than did Hispanic White women (13.9%; P < .001). Hispanic White women had higher rates of node-positive disease (23.2%) versus NH White women (14.4%) but slightly lower rates than Hispanic (24.6%) and NH Black women (24.5%; P < .001). Hispanic White women had longer TTS versus NH White women regardless of treatment sequence (adjusted means: adjuvant chemotherapy, 42.71 v 38.60 days; neoadjuvant chemotherapy, 208.55 v 201.14 days; both P < .001), but there were no significant racial differences in TTS among Hispanic patients. After adjustment, Hispanic White women (hazard ratio, 0.77 [95% CI, 0.74 to 0.81]) and Black women (hazard ratio, 0.75 [95% CI, 0.58 to 0.96]) had improved OS versus NH White women (reference) and Black women (hazard ratio, 1.15 [95% CI, 1.12 to 1.18]; all P < .05). CONCLUSION: Hispanic women had improved OS versus NH women, but racial differences in tumor subtype and nodal stage among Hispanic women highlight the importance of disaggregating racial/ethnic data in breast cancer research.

BACKGROUND. In 2002, breast cancer patients with supraclavicular nodal metastases (cN3c) were downstaged from AJCC stage IV to IIIc, prompting management with locoregional treatment. We sought to estimate the impact of multimodal therapy on overall survival (OS) in a contemporary cohort of cN3c patients. METHODS. Women ≥ 18 years with cT1-T4c/cN3c invasive breast cancer who underwent systemic therapy were identified from the 2004–2016 National Cancer Database. We compared three patient cohorts: (a) cN3c + multimodal therapy (systemic therapy, surgery, and radiation); (b) cN3c + non-standard therapy; and, (c) cM1. Logistic regression identified factors associated with receipt of multimodal therapy and Kaplan–Meier was used to estimate unadjusted OS. The Cox proportional hazards model estimated effects of diagnosis and treatment on OS after adjustment. RESULTS. Overall, 1827 (3.7%) patients with cN3c disease and 46,919 (96.3%) cM1 patients were identified. Of cN3c patients, 74.5% (n = 1362) received multimodal therapy and 25.5% (n = 465) received non-standard therapy; receipt of multimodal therapy was associated with improved 5-year OS (multimodal: 59% vs. M1: 28% vs. non-standard: 28%, log-rank p < 0.001). Adjusting for covariates, non-standard therapy was associated with an increased risk of death compared with receipt of multimodal therapy (HR 2.20, 95% CI 1.71–2.83, p < 0.001). Private insurance was the only patient characteristic associated with a greater likelihood of receiving multimodal therapy (OR 2.81; 95% CI, 1.64–4.82; p < 0.001). CONCLUSION. Women with cN3c breast cancer who received multimodal therapy demonstrated improved overall survival when compared with patients undergoing non-standard therapy and those with metastatic (M1) disease. Although selection bias may contribute to worse overall survival among cN3c patients undergoing non-standard therapy, national guidelines should encourage locoregional treatment in carefully selected patients.

Background Underinsured and uninsured surgical-oncology patients are at higher risk of perioperative morbidity and mortality. Curricular innovation is needed to train medical students to work with this vulnerable population. We describe the implementation of and early educational outcomes from a student-initiated pilot program aimed at improving medical student insight into health disparities in surgery. Materials/Methods First-year medical students participated in a dual didactic and perioperative-liaison experience over a 10-month period. Didactic sessions included surgical-skills training and faculty-led lectures on financial toxicity and management of surgical-oncology patients. Students were partnered with uninsured and Medicaid patients receiving surgical-oncology care and worked with these patients by providing appointment reminders, clarifying perioperative instructions, and accompanying patients to surgery and clinic appointments. Students’ interest in surgery and self-reported comfort in 15 Association of American Medical Colleges core competencies were assessed with preparticipation and postparticipation surveys using a 5-point Likert scale. Results Twenty-four first-year students were paired with 14 surgical-oncology patients during the 2017-2018 academic year. Sixteen students (66.7%) completed both preprogram and postprogram surveys. Five students (31.3%) became “More Interested” in surgery, whereas 11 (68.8%) reported “Similar Interest or No Change.” Half of the students (n = 8) felt more prepared for their surgery clerkship after participating. Median self-reported comfort improved in 7/15 competencies including Oral Communication and Ethical Responsibility. All students reported being “Somewhat” or “Extremely Satisfied” with the program. Conclusions We demonstrate that an innovative program to expose preclinical medical students to challenges faced by financially and socially vulnerable surgical-oncology patients is feasible and may increase students’ clinical preparedness and interest in surgery.

Background The clinical behavior of breast cancer varies by racial and ethnic makeup (REM), but the impact of REM on the clinical outcomes of breast atypia remains understudied. We examined the impact of REM on risk of underlying or subsequent carcinoma following a diagnosis of breast atypia. Methods In this retrospective, single-institution chart review, adult women diagnosed with breast atypia (atypical ductal hyperplasia, atypical lobular hyperplasia, or lobular carcinoma in situ) were stratified by REM. Regression modeling was used to estimate risk of underlying or subsequent carcinoma. Results We identified 539 patients with breast atypia, including 15 Hispanic (2.8%), 127 non-Hispanic black (23.6%), and 397 non-Hispanic white women (73.7%). Diagnoses included 75.1% atypical ductal hyperplasia (n = 405), 4.6% atypical lobular hyperplasia (n = 25), and 20.2% lobular carcinoma in situ (n = 109). Rates for each type of atypia did not vary by REM (P = 0.33). Of those with atypia on needle biopsy, the rate of underlying carcinoma at excision was 17.3%. After adjustment, REM was not associated with greater risk for carcinoma at excision (P = 0.41). Of those with atypia alone on surgical excision, the rate of a subsequent carcinoma diagnosis was 15.4% (median follow-up 49 mo). REM was not associated with a long-term risk for carcinoma (P = 0.37) or differences in time to subsequent carcinoma (log-rank P = 0.52). Chemoprevention uptake rates were low (10.6%), especially among Hispanic (0%) and non-Hispanic black (3.8%) patients (P = 0.01). Conclusions Among patients with atypia, REM does not appear to influence type of histologic atypia, risk for carcinoma, or clinical outcome, despite differences in chemoprevention rates.

BACKGROUND. Men represent a small proportion of breast cancer diagnoses, and they are often excluded from clinical trials. Current treatments are largely extrapolated from evidence in women. We compare practice patterns between men and women with breast cancer following the publication of several landmark clinical trials in surgery. PATIENTS AND METHODS. Patients with invasive breast cancer (2004–2015) from the National Cancer Data Base were identified; subcohorts were created based on eligibility for NSABP-B06, CALGB 9343, and ACOSOG Z0011. Practice patterns were stratified by gender and compared. Cox proportional hazards regression analyses were utilized to estimate the association between OS and gender. RESULTS. Of the 1,664,746 patients identified, 99% were women and 1% were men. Among NSABP-B06 eligible men, mastectomy rates did not change (consistently ~ 80%), and their adjusted OS was minimally worse compared with women (HR 1.19, 95% CI 1.11–1.28). Following publication of CALGB 9343, omission of radiation after lumpectomy was less likely in men and lagged behind that of women, despite similar OS (male HR 0.92, 95% CI 0.59–1.44). Application of ACOSOG Z0011 findings resulted in deescalation of axillary surgery for men and women with comparable OS (male HR 0.69, 95% CI 0.33–1.45). CONCLUSIONS. Uptake of clinical trial results for men with breast cancer often mirrors that for women, despite exclusion from these studies. Furthermore, when study findings were applied to eligible patients, men and women demonstrated similar survival. Observational studies can help inform the potential application of study findings to this unique population and improve patient enrollment in clinical trials.

To determine whether the association between overall survival (OS) and response to neoadjuvant chemotherapy (NACT) in breast cancer patients varies with tumor subtype and anatomic extent of pathologic complete response (pCR).pCR after NACT predicts improved OS in breast cancer, but it is unclear whether pCR limited to the breast or axilla is also associated with OS.Women with cT1-3/cN0-1 breast cancer diagnosed in 2010 to 2014 who underwent surgery following NACT were identified in the NCDB and divided into 4 subtypes based on reported hormone receptor (HR) and human epidermal growth factor receptor 2 (HER2) status. Kaplan-Meier curves and Cox proportional hazards models were used to estimate OS. Multivariate logistic regression was used to identify factors associated with post-NACT response, defined as upstage (yp stageclinical stage); no change (clinical stage = yp stage); overall (breast+axilla, ypT0N0), breast-only (ypT0N1/N1mic), or node-only (ypT1-3N0) pCR.Of 33,162 identified patients, 20,265 experienced overall pCR (n = 6370, 19.2%), breast-only pCR (n = 494, 1.5%), node-only pCR (n = 1133, 3.4%), no stage change (n = 9641, 29.1%), or upstage (n = 2627, 7.9%). Compared with no stage change, breast-only pCR was associated with improved OS in triple-negative disease [hazard ratio = 0.58, 95% confidence interval (95% CI) = 0.37-0.89], and node-only pCR was associated with improved OS in both triple-negative (hazard ratio = 0.55,95% CI = 0.39-0.76) and HR+/HER2- disease (hazard ratio = 0.54, 95% CI = 0.33-0.89). For patients achieving overall (breast+axilla) pCR, unadjusted 5-year OS was 0.94 (95% CI = 0.93-0.95), with no difference between patients who were cN0 (hazard ratio = 0.95, 95% CI = 0.93-0.96) or cN1 (hazard ratio = 0.94, 95% CI = 0.92-0.96) at diagnosis.In node-positive patients, pCR limited to either the breast or axilla predicts survival for select receptor subtypes. In patients achieving pCR in both the breast and axilla, survival is driven by response to NACT rather than presenting cN stage.

Recent studies suggest that surgical lymph node (LN) evaluation may be omitted in select elderly breast cancer patients as it may not influence adjuvant therapy decisions. To evaluate differences in adjuvant therapy receipt and overall survival (OS), we compared clinically node-negative (cN0) elderly patients who did and did not undergo axillary surgery. Patients aged ≥70 years in the National Cancer Database (2004–2014) with cT1-3, cN0 breast cancer were divided into two cohorts—those with surgical LN evaluation (one or more nodes removed) and those without (no nodes removed). Propensity scores were used to match patients based on age, year of diagnosis, tumor grade, cT stage, estrogen receptor status, and Charlson–Deyo comorbidity score. A Cox proportional hazards model was used to estimate the effect of LN surgery on OS. Overall, 133,778 patients were matched, of whom 102,247 patients (76.4%) underwent nodal surgery. Patients undergoing nodal surgery were more likely to receive chemotherapy (pN1-3: 22.2%; pN0: 5.8%; cN0-no nodal surgery: 2.8%; p

BACKGROUND. Up to 50% of all women encounter benign breast problems. In contrast to breast cancer, high-level evidence is not available to guide treatment. Management is therefore largely based on individual physician experience/training. The American board of internal medicine (ABIM) initiated its Choosing Wisely(®) campaign to promote conversations between patients and physicians about challenging the use of tests or procedures which may not be necessary. The American society of breast surgeons (ASBrS) Patient safety and quality committee (PSQC) chose to participate in this campaign in regard to the management of benign breast disease. METHODS. The PSQC solicited initial candidate measures. PSQC surgeons represent a wide variety of practices. The resulting measures were ranked by modified Delphi appropriateness methodology in two rounds. The final list was approved by ASBrS and endorsed by the ABIM. RESULTS. The final five measures are as follows. (1) Don’t routinely excise areas of pseuodoangiomatous stromal hyperplasia (PASH) of the breast in patients who are not having symptoms from it. (2) Don’t routinely surgically excise biopsy-proven fibroadenomas that are < 2 cm. (3) Don’t routinely operate for a breast abscess without an initial attempt to percutaneously aspirate. (4) Don’t perform screening mammography in asymptomatic patients with normal exams who have less than a 5-years life expectancy. (5) Don’t routinely drain nonpainful, fluid-filled cysts. CONCLUSIONS. The ASBrS Choosing Wisely(®) measures that address benign breast disease management are easily accessible to patients via the internet. Consensus was reached by PSQC regarding these recommendations. These measures provide guidance for shared decision-making.

Metaplastic breast cancer (MBC) is characterized by chemoresistance and hematogenous spread. We sought to identify factors associated with improved MBC outcomes and increased likelihood of MBC diagnosis. Women ≥ 18 years of age with stage I–III MBC and non-MBC diagnosed between 2010 and 2014 were identified in the National Cancer Data Base. Kaplan–Meier and multivariate Cox proportional hazards models were used to estimate associations with overall survival (OS). Multivariate logistic regression identified factors associated with MBC diagnosis. Overall, 2451 MBC and 568,057 non-MBC patients were included; 70.3% of MBC vs. 11.3% of non-MBC patients were triple negative (p

IMPACT: This work will inform and improve the way we assess and treat distress in women with endometrial cancer. OBJECTIVES/GOALS: Distress from cancer is associated with worse processes of care. Differences in outcomes by race/ethnicity in endometrial cancer (EC) are well documented, but differences in distress have not been previously explored. Here we characterize the association between race/ethnicity, distress scores, and stressors reported by patients with EC. METHODS/STUDY POPULATION: Patients presenting to a single academic outpatient gynecologic oncology practice for initial evaluation of known EC from January 2013-May 2020 were included. The electronic health record was used to abstract demographics, National Comprehensive Cancer Network Distress Thermometer and Problem List (NCCN DT) scores and stressor categories (physical, emotional, spiritual, practical, and family) from the initial encounter. Referral to support services occurs at NCCN DT score ≥4. We excluded women who received prior cancer-directed therapy and those without an initial NCCN DT score. Summary statistics were tabulated for demographics. Mann-Whitney U tests were used for inter-group difference on continuous variables and 2-sample tests for equality of proportions were used for binary variables. RESULTS/ANTICIPATED RESULTS: 412 non-Hispanic White (NHW, mean age 63) and 149 non-Hispanic Black (NHB, mean age 65) women were included in our analysis. More NHB women presented with high-grade EC (53.7%) vs NHW women (21.9%) and fewer NHB women were privately insured (32% vs 52%). Median distress scores were higher in NHW women compared to their NHB counterparts (4 vs. 2, p30% more high-risk histology cancers in this cohort. This difference leads to disparities in referral to additional support services, which may affect quality of care and quality of life.

Purpose: In Tanzania, women are diagnosed at advanced breast cancer stages. The reasons for this are multifactorial and have not been systematically investigated in the Kilimanjaro Region. This study aimed to identify reasons for advanced stage breast cancer at time of diagnosis. Methods: Four focus group discussions and 8 semi- structured in-depth interviews were conducted among health care providers (HCP) and traditional healers from five health care facilities (1 regional and 2 district hospitals) and two urban and rural communities in Kilimanjaro, Tanzania. Thematic coding via grounded theory technique was done by two independent reviewers. Results: Twenty HCP (10 doctors and 10 nurses) and 8 traditional healers participated in the study. The average ages for doctors were 38, nurses 33, and traditional healers 50. Among HCP, the most common reasons for advanced stage breast cancer at time of diagnosis were patients initially seeking care from traditional healers, and patient distrust of conventional medicine. Among traditional healers, the most common reasons were: delayed initiation of biomedical treatment due to long turnaround of pathology results, inability to pay for diagnostic workup and treatment, and transportation issues. Both groups stated lack of patient breast cancer knowledge. Conclusions: There was agreement that lack of adequate breast cancer knowledge and awareness as a very common reason for advanced disease presentation among HCP and traditional healers. Community health education must be designed to adopt socio-cultural and religious doctrines to alleviate the misconceptions and knowledge gap. Health system interventions are also needed to facilitate access to timely, affordable, and quality breast cancer diagnosis and treatment Citation Format: Elizabeth F. Msoka, Lily Gutnik, Agnes M.
