BACKGROUND: In the US, African Americans have a high death rate from triple-negative breast cancer (TNBC), characterized by lack of hormone receptors (ER, PR, HER2/ERRB2) which are otherwise valuable targets of chemotherapy. There is a need to identify novel targets that negatively impact TNBC tumorigenesis. TNBCs release an abundance of lactic acid, under normoxic, hypoxic and hyperoxic conditions; this referred to as the Warburg effect. Accumulated lactic acid sustains peri-cellular acidity which propels metastatic invasion and malignant aggressive transformation...

Breast cancer (BC) continues to be the most frequently diagnosed cancer in American women, which disproportionately affects women of African-American (AA) descent. Previously, we reported greater serum levels of resistin in AA BC patients relative to Caucasian-American (CA) patients, and established its role in growth and aggressiveness of breast tumor cells. Here we have investigated the role of resistin in BC-chemoresistance. MDA-MB-231 and MDA-MB-468 BC cells of CA and AA origin, respectively, were incubated with resistin prior to doxorubicin treatment...

Oncotype DX recurrence score (ODX) can predict risk of invasive breast cancer recurrence and benefit of chemotherapy. Literature is limited on the relationship of ODX and race in women with hormone receptor positive and node negative/positive disease. Our study examines the relationship between race and clinical characteristics within a population of highly screened women with newly diagnosed breast cancer. The institutional Breast Cancer Database was queried for patients with newly diagnosed breast cancer between January2010 and March2015...

Carcinomas arising from breast hamartomas are exceedingly rare. We present the first reported case of an African-American female presenting with a right breast lump and a subsequent mammogram suggestive of a hamartoma. She later underwent lumpectomy and was found to have HER2+ invasive ductal carcinoma (IDC) arising from a hamartoma. She was amenable to HER2-targeted trastuzumab, hormone therapy and adjuvant radiation but declined chemotherapy. In a review of the literature, IDC is the predominant neoplastic type found in hamartomas...

Breast cancer is second most prevalent cancer in women, and the second only to lung cancer in cancer-related deaths. It is a heterogeneous disease and has several subtypes based on the presence or absence of hormone receptors and/or human epidermal growth factor receptor 2 (HER2). Hormone receptor-positive and HER2-enriched cancers can be targeted using hormone and HER2-targeting therapies such as trastuzumab or lapatinib. However, triple-negative breast cancers (TNBCs) do not express any of the receptors and therefore are resistant to most targeted therapies, and cytotoxic chemotherapies are the only viable option available for the treatment of TNBCs...

African Americans suffer a greater burden of mortality from breast, cervical, and colorectal cancers than other groups in the United States. Early detection through timely screening can improve survival outcomes; however, cost is frequently reported as a barrier to screening. Federally qualified health centers (FQHCs) provide preventive and primary care to underserved populations regardless of ability to pay, positioning them to improve cancer screening rates. The purpose of this study was to examine the influence of concern about health care cost (cost concern) and awareness of low-cost health care (awareness) on cancer screening among 236 African Americans within an FQHC service area using self-report surveys...

BACKGROUND: African American (AA) women are more likely to be given a diagnosis of breast cancer at an early age, experience morbidity after treatment, and exhibit disparities in survivorship. Although psychosocial well-being is largely studied among breast cancer survivors, data are sparse regarding young AA survivors. OBJECTIVE: This integrative review examined psychosocial concerns in survivorship among young AA survivors using a quality-of-life framework. METHODS: PubMed, CINHAL, EMBASE, PsychINFO, and Scopus were searched for articles exploring psychosocial well-being in young AA survivors...

Nuclear KIFC1 (nKIFC1) predicts worse outcomes in breast cancer, but its prognostic value within racially distinct triple-negative breast cancer (TNBC) patients is unknown. Thus, nKIFC1 expression was assessed by immunohistochemistry in 163 African American (AA) and 144 White TNBC tissue microarrays (TMAs) pooled from four hospitals. nKIFC1 correlated significantly with Ki67 in White TNBCs but not in AA TNBCs, suggesting that nKIFC1 is not merely a surrogate for proliferation in AA TNBCs. High nKIFC1 weighted index (WI) was associated with significantly worse overall survival (OS), progression-free survival (PFS), and distant metastasis-free survival (DMFS) (Hazard Ratios [HRs] = 3...

OBJECTIVE: African American (AA) women have disproportionately high rates of cardiovascular (CV) risk factors that, coupled with potentially cardiotoxic breast cancer (BC) therapies, place them at risk of adverse CV outcomes. The purpose of this study was to assess CV risk factors among white and AA BC survivors and perceptions of patient-provider CV-related communication and post-treatment information needs. METHODS: Early-stage, English-speaking BC survivors were recruited through community-based survivorship organizations/clinics in New Jersey...

BACKGROUND: There is a persistent racial survival disparity between African American (AA) and white women with breast cancer. There is evidence that symptom incidence, associated distress, and overall cancer-related distress may be unexplored, important contributing factors. The purpose of the current study was to: 1) describe and compare the number of chemotherapy-related symptoms and associated distress among AA women with breast cancer over the course of chemotherapy at 3 time points (at baseline before initiating chemotherapy, midpoint, and at the completion of chemotherapy); and 2) to describe the relationship between the number of chemotherapy-related symptoms and overall cancer distress compared with the ability to receive at least 85% of the prescribed chemotherapy within the prescribed timeframe...

BACKGROUND: Neighborhood socioeconomic status (nSES) has been found to be associated with breast cancer risk. It remains unclear whether this association applies across racial/ethnic groups independent of individual-level factors, and is attributable to other neighborhood characteristics. METHODS: We examined the independent and joint associations of education and nSES with odds of breast cancer. Residential addresses were geocoded for 2,838 cases and 3,117 controls and linked to nSES and social and built environment characteristics...

BACKGROUND: Observational and biologic studies suggest that aspirin is a promising prevention therapy for breast cancer. However, clinical trials to date have not corroborated this evidence, potentially due to study design. We evaluated the effect of aspirin on mammographic density (MD), an established modifiable risk factor for breast cancer. METHODS: Electronic medical records from the University of Pennsylvania were evaluated for women who underwent screening mammography, saw their primary care provider, and had a confirmed list of medications during 2012-2013...

BACKGROUND: More than a third of hospitalized women are both overdue for breast cancer screening and at high risk for developing breast cancer. The purpose of the study was to evaluate if inpatient breast cancer screening education, scheduling an outpatient mammography appointment before hospital discharge at patients' convenience, phone call reminders, and a small monetary incentive ($10) would result in improved adherence with breast cancer screening for these patients. METHODS: A prospective intervention pilot study was conducted among 30 nonadherent women aged 50-75 years hospitalized to a general medicine service...

146 Background: Emotional distress and poor symptom management are highly prevalent among patients with metastatic breast cancer (MBC). A high disease burden can further negatively impact these patients' quality of life. To address the evolving survivorship needs in their trajectory from initial diagnosis of advanced disease to end-of-life care, patients with MBC require prompt assessment, reevaluation, and specialized support services. Limited survivorship resources are devoted to this patient population and greater attention to their needs is warranted...
