The multifaceted involvement of centrosome amplification (CA) in tumorigenesis is coming into focus following years of meticulous experimentation, which have elucidated the powerful abilities of CA to promote cellular invasion, disrupt stem cell division, drive chromosomal instability (CIN), and perturb tissue architecture, activities that can accelerate tumor progression. Integration of the extant in vitro, in vivo, and clinical data suggests that in some tissues CA may be a tumor-initiating event, in others a consequential "hit" in multistep tumorigenesis, and in still others non-tumorigenic...

In addition to rising type 2 diabetes and breast cancer incidence rates worldwide, diabetes may also increase breast cancer risk, and the association may vary by ethnicity. This review summarizes published data evaluating the association between diabetes and breast cancer in women of Asian, Hispanic and African American ancestry while considering a measure of obesity, body mass index (BMI). Published reports were identified through a search of PubMed and previous publications. Of 15 age-adjusted studies, 11 reported on Asian women from various countries, 3 on Hispanics and 1 on African Americans...

PURPOSE: Rates of implant failure, wound healing delay, and infection are higher in patients having radiation therapy (RT) after tissue expander (TE) and permanent implant reconstruction. We investigated pretreatment risk factors for TE implant complications. PATIENTS AND METHODS: 127 breast cancer patients had TE reconstruction and radiation. For 85 cases of bilateral TE reconstruction, the non-irradiated breast provided an internal control. Comparison of differences in means for continuous variables used analysis of variance, then multiple pairwise comparisons with Bonferroni correction of p value...

Sequencing large cohorts of ethnically homogeneous individuals yields genetic insights with implications for the entire population rather than a single individual. In order to evaluate the genetic basis of certain diseases encountered at high frequency in the Ashkenazi Jewish population (AJP), as well as to improve variant annotation among the AJP, we examined the entire exome, focusing on specific genes with known clinical implications in 128 Ashkenazi Jews and compared these data to other non-Jewish populations (European, African, South Asian and East Asian)...

OBJECTIVE: Breast cancer has psychological consequences that impact quality of life (QOL). We examined factors associated with negative psychological consequences of a breast cancer diagnosis, in a diverse sample of 910 recently diagnosed patients (378 African-American, 372 White, and 160 Latina). METHODS: Patients completed an in-person interview as part of the Breast Cancer Care in Chicago study within an average of four months from diagnosis. The Cockburn negative psychological consequences of breast cancer screening scale was revised to focus on a breast cancer diagnosis...

BACKGROUND AND PURPOSE: Social connection has a positive influence on cancer survivorship and has been targeted in intervention work. We examined whether the formation of social connection is influenced by fear, fatalism, and isolation. METHODS: We conducted a mediation analysis on data from an intervention study with African American breast cancer survivors to investigate whether fear, fatalism, and isolation conveyed effects on social connection. RESULTS: Although results indicated that there were no significant mediated effects of the intervention through these variables, we garnered information about action and conceptual theories underlying the program that inform future work...

Breast cancer is the second leading cause of cancer related deaths among women aged 40-55 in the United States and currently affects more than one in ten women worldwide. It is also one of the most diagnosed cancers in women both in wealthy and poor countries. Fortunately, the mortality rate from breast cancer has decreased in recent years due to increased emphasis on early detection and more effective treatments in White population. Although the mortality rates have declined in some ethnic populations, the overall cancer incidence among African American and Hispanic populations has continued to grow...

BACKGROUND: Women younger than 45 years old have lower rates of breast cancer, but higher risk of recurrence and mortality after a cancer diagnosis. African American women are at risk for early onset and increased mortality; Ashkenazi Jewish women are at risk for genetic mutations leading to breast and ovarian cancer. Although younger women are encouraged to talk to doctors about their family history, little is known about these discussions. MATERIALS AND METHODS: In 2015, 167 women aged 18-44 years participated in 20 focus groups segmented by geographic location, age, race/ethnicity, and family history of breast and ovarian cancer...

Importance: African Americans have the highest breast cancer mortality rate. Although racial difference in the distribution of intrinsic subtypes of breast cancer is known, it is unclear if there are other inherent genomic differences that contribute to the survival disparities. Objectives: To investigate racial differences in breast cancer molecular features and survival and to estimate the heritability of breast cancer subtypes. Design, Setting, and Participants: Among a convenience cohort of patients with invasive breast cancer, breast tumor and matched normal tissue sample data (as of September 18, 2015) were obtained from The Cancer Genome Atlas...

BACKGROUND: Variants of unknown significance (VUSs) have been identified in BRCA1 and BRCA2 and account for the majority of all identified sequence alterations. Notably, VUSs occur disproportionately in people of African descent hampering breast cancer (BCa) management and prevention efforts in the population. Our study sought to identify and characterize mutations associated with increased risk of BCa at young age. METHODS: In our study, the spectrum of mutations in BRCA1 and BRCA2 was enumerated in a cohort of 31 African American women of early age at onset breast cancer, with a family history of breast or cancer in general and/or with triple negative breast cancer...

Although increased awareness leading to early detection and prevention, as well as advancements in treatment strategies, have resulted in superior clinical outcomes, African American women with breast cancer continue to have greater mortality rates, compared to Caucasian American counterparts. Moreover, African American women are more likely to have breast cancer at a younger age and be diagnosed with aggressive tumor sub-types. Such racial disparities can be attributed to socioeconomic differences, but it is increasingly being recognized that these disparities may indeed be due to certain genetic and other non-genetic biological differences...

Racial disparities in breast cancer survivorship are a major concern nationally. How survivors cope with cancer and re-frame their lives is a critical part of survivorship. Community-academic research partnerships may facilitate access to much-needed psychosocial support for African American survivors and caregivers in rural areas, but drivers of successful intervention implementation are not well understood. The purpose of this study was to describe the training and evaluation of Community Coaches and Guides (i...

PURPOSE: Epidemiological studies suggest that short sleep duration and poor sleep quality may increase breast cancer risk. However, whether sleep is associated with breast tumor aggressiveness characteristics has largely been unexplored. METHODS: The study included 4171 non-Hispanic whites (NHW) and 235 African Americans (AA) diagnosed with incident, primary, invasive breast cancer in the Women's Health Initiative (WHI) Observational Study (1994-2013). We used logistic regression to examine the association of baseline sleep (sleep duration, sleep quality, WHI Insomnia Rating Scale) with tumor grade, stage, hormone receptor status, HER2 status...

BACKGROUND: Data show that yoga is effective for improving health-related outcomes in breast cancer survivors. While breast cancer is the most commonly diagnosed cancer among African-American women (AAW), AAW are less likely to engage in yoga compared to other ethnic groups. The goals of the current study were to assess the feasibility of an 8-week restorative yoga program among African-American breast cancer survivors (AA BCS). Specifically, study aims were to (1) measure changes in study outcomes in a restorative yoga (RY) group compared to a wait list control group, (2) assess adherence to the RY program, and (3) assess program satisfaction among study participants...

Recent advances in next generation sequencing have enabled panel gene testing, or simultaneous testing for mutations in multiple genes for a clinical condition. With more extensive and widespread genetic testing, there will be increased detection of genes with moderate penetrance without established clinical guidelines and of variants of uncertain significance (VUS), or genetic variants unknown to either be disease-causing or benign. This study surveyed 232 patients who underwent genetic counseling for hereditary breast and ovarian cancer to examine the impact of panel gene testing on psychological outcomes, patient understanding, and utilization of genetic information...

BACKGROUND: Li-Fraumeni Syndrome (LFS) is a rare disease with autosomal dominant inheritance linked to germline mutations of tumor suppressor gene TP53. These patients are predisposed to malignancies such as sarcoma, breast cancer, leukemia, and other malignancies. Breast cancer, the most common malignancy in adult patients with LFS, has an early-onset presentation and is usually treated as per the guidelines for the general population due to the limited literature about breast cancer in LFS...

Importance: Variation in cancer incidence and outcome has well-documented correlations with racial/ethnic identity. In the United States, the possible genetic and ancestral hereditary explanations for these associations are confounded by socioeconomic, cultural, and lifestyle patterns. Differences in the breast cancer burden of African American compared with European/white American women represent one of the most notable examples of disparities in oncology related to racial/ethnic identity...
