BACKGROUND: The study of physical activity in cancer survivors has been limited to one cause, one effect relationships. In this exploratory study, we used recursive partitioning to examine multiple correlates that influence physical activity compliance rates in cancer survivors. METHODS: African American breast cancer survivors (N = 267, Mean age = 54 years) participated in an online survey that examined correlates of physical activity. Recursive partitioning (RP) was used to examine complex and nonlinear associations between sociodemographic, medical, cancer-related, theoretical, and quality of life indicators...

Church-based interventions have been used to reach racial/ethnic minorities. In order to develop effective programs, we conducted a comprehensive systematic review of faith-based cancer prevention studies (2005~2016) to examine characteristics and promising strategies. Combination terms "church or faith-based or religion," "intervention or program," and "cancer education or lifestyle" were used in searching the five major databases: CINAHL; ERIC; Health Technology Assessments; MEDLINE; and PsycInfo. A total of 20 studies met study criteria...

BACKGROUND: African American (AA) women have higher incidence of aggressive, young-onset (<40 years) breast cancers. Young- and older-onset disease may have distinct tumor biologies and etiologies; however, studies investigating age differences among AA women have been rare and generally underpowered. METHODS: We examined tumor characteristics and breast cancer risk factors associated with premenopausal young (<40) vs. older (≥40) AA women's breast cancer in the African American Breast Cancer Epidemiology and Risk Consortium (2,008 cases and 5,144 controls)...

PURPOSE: Despite benefits for patients, sustainability of breast cancer navigation programs is challenging due to the lack of reimbursement for navigators. This analysis describes distress reported by breast cancer patients to navigators and the impact of navigation on healthcare utilization for older adults with breast cancer. METHODS: We conducted a retrospective cohort study of Medicare administrative claims data and patient-reported distress assessments. The primary outcome was Medicare spending per beneficiary per quarter...

PURPOSE: Triple-negative breast cancer (TNBC) is most prevalent in young women of African ancestry (WAA) compared to women of other ethnicities. Recent studies found a correlation between high expression of the transcription factor Kaiso, TNBC aggressiveness, and ethnicity. However, little is known about Kaiso expression and localization patterns in TNBC tissues of WAA. Herein, we analyze Kaiso expression patterns in TNBC tissues of African (Nigerian), Caribbean (Barbados), African American (AA), and Caucasian American (CA) women...

INTRODUCTION: Toll-like receptor 9 (TLR9) is an innate immune system DNA-receptor that regulates tumor invasion and immunity in vitro. Low tumor TLR9 expression has been associated with poor survival in Caucasian patients with triple negative breast cancer (TNBC). African American (AA) patients with TNBC have worse prognosis than Caucasians but whether this is due to differences in tumor biology remains controversial. We studied the prognostic significance of tumor Toll like receptor-9 (TLR9) protein expression among African American (AA) triple negative breast cancer (TNBC) patients...

OBJECTIVE: The experience of an illness such as breast cancer is not a static event. Just as physiological needs change as a patient transitions through diagnosis, treatment, to long-term survivorship, so too will their needs for social support. We applied a transitions theory framework to explore how African American women with breast cancer conceptualized and experienced support along their breast cancer journey. DESIGN: We recruited 16 African American women with breast cancer from a regional cancer center in South Carolina to complete qualitative, semi-structured interviews...

BACKGROUND: Given the wide adoption of human epidermal growth factor receptor 2 (HER2)-targeted therapies for advanced HER2-positive breast cancer, we studied the natural history of patients with HER2-positive breast cancer brain metastases (BCBM) over time. PATIENTS AND METHODS: Patients with HER2-positive BCBM identified from a prospectively maintained database at the University of North Carolina were divided into 3 cohorts by year of BCBM diagnosis. Cohorts were selected by year of HER2-targeted therapy US Food and Drug Administration approval...

African-American women are more likely to develop aggressive breast cancer at younger ages and experience poorer cancer prognoses than non-Hispanic Caucasians. Deficiency in repair of DNA by homologous recombination (HR) is associated with cancer development, suggesting that mutations in genes that affect this process may cause breast cancer. Inherited pathogenic mutations have been identified in genes involved in repairing DNA damage, but few studies have focused on African-Americans. We screened for germline mutations in seven HR repair pathway genes in DNA of 181 African-American women with breast cancer, evaluated the potential effects of identified missense variants using in silico prediction software, and functionally characterized a set of missense variants by yeast two-hybrid assays...

Background: The U.S. Hispanic/Latino population is heterogeneous both socioculturally and by the proportion of European, Indigenous American, and African ancestry of the regions from which individuals originate. A previous study reported that genetic ancestry was associated with breast cancer survival among Latinas, independent of sociodemographic and tumor characteristics, suggesting that a genetic factor associated with ancestry may affect breast cancer survival.Methods: We evaluated the association of genetic ancestry with breast cancer outcomes among 506 Latina women with invasive breast cancer in the Pathways Study, a cohort study within Kaiser Permanente, an integrated health care delivery system...

African American women are more likely to be diagnosed with late stage breast cancer, due in part to low participation in screening procedures. The purpose of this study was to explore the differences among African American women who were compliant and noncompliant with standard mammography screening recommendations. The study participants were African American women (N = 599) over the age of 40 with no history of cancer, who were recruited to attend a local community health event. Findings revealed that 78 percent of the women reported having had a mammogram within the past year, whereas 22 percent had not...

Background: African American breast cancer patients have lower frequency of hormone receptor-positive (HR+)/human epidermal growth factor receptor 2 (HER2)-negative disease and higher subtype-specific mortality. Racial differences in molecular subtype within clinically defined subgroups are not well understood. Methods: Using data and biospecimens from the population-based Carolina Breast Cancer Study (CBCS) Phase 3 (2008-2013), we classified 980 invasive breast cancers using RNA expression-based PAM50 subtype and recurrence (ROR) score that reflects proliferation and tumor size...

PURPOSE: Racial disparity of breast cancer in each subtype and substage is not clear. METHODS: We reviewed 156,938 patients with breast cancer from 2010 to 2012 from the National Cancer Institute Surveillance, Epidemiology, and End Results database. Breast cancer was subtyped by hormone receptor (HR) and human epidermal growth factor 2 (HER2) status as HR+/HER2-, HR+/HER2+, HR-/HER2+, and HR-/HER2-. RESULTS: African American (AA) patients had worse overall survival (OS) and breast cancer cause-specific survival (BCSS) in HR+/HER2- stages III and IV breast cancer and HR-/HER2+ stage IV cancer; they had worse OS but not BCSS in HR+ /HER2- stage II cancer and HR-/HER2- stage II cancer...

BACKGROUND: Racial disparities in the incidence of major cancers may be attributed to differences in the prevalence of established, modifiable risk factors such as obesity, smoking, physical activity and diet. METHODS: Data from a prospective cohort of 566,398 adults aged 50-71 years, 19,677 African-American and 450,623 Whites, was analyzed. Baseline data on cancer-related risk factors such as smoking, alcohol, physical activity and dietary patterns were used to create an individual adherence score...

Adult height has been positively associated with breast cancer risk. The timing of pubertal growth - as measured by age at menarche and age at attained height - may also influence risk. We evaluated associations of adult height, age at attained height, and age at menarche with incidence of invasive breast cancer in 55,687 African American women in the prospective Black Women's Health Study. Over 20 years, 1,826 invasive breast cancers [1,015 estrogen receptor (ER) positive; 542 ER negative] accrued. We used multivariable Cox proportional hazards regression to estimate hazards ratios (HRs) and 95% confidence intervals (CIs) for associations with breast cancer overall and by ER status, mutually adjusted for the three factors of interest...

BACKGROUND: Lung transplantation remains an important potential therapeutic option for end-stage lung disease. It can improve quality of life and in some cases be a life-lengthening therapy. Despite the possible benefits, there are also many potential complications following transplantation. Here we describe a novel presentation of nontuberculous mycobacterium manifesting as an endobronchial mass developing 4 years after lung transplantation. CASE PRESENTATION: A 66-year-old African-American woman presented with progressive dyspnea, cough, and persistent wheezing of 2 months' duration...

PURPOSE: To determine the prevalence of nipple-sparing mastectomy (NSM) and its long-term survival outcomes in breast cancer patients. METHOD: We used the Surveillance, Epidemiology, and End Results database and identified 2,440 breast cancer patients who received NSM during 1998-2013. We used chi-square and binary logistic regression to identify factors associated with the use of radiotherapy after NSM. We used Kaplan-Meier analysis to estimate cancer-specific survival (CSS) and overall survival (OS)...

BACKGROUND: Hispanic/Latino populations are a genetically admixed and heterogeneous group, with variable fractions of European, Indigenous American and African ancestries. The molecular profile of breast cancer has been widely described in non-Hispanic Whites but equivalent knowledge is lacking in Hispanic/Latinas. We have previously reported that the most prevalent breast cancer intrinsic subtype in Colombian women was Luminal B as defined by St. Gallen 2013 criteria. In this study we explored ancestry-associated differences in molecular profiles of Luminal B tumors among these highly admixed women...
