PURPOSE: Fatigue is a prevalent and burdensome effect of breast cancer. Fatigue has been linked to chronic inflammation, and diets high in antioxidant nutrients have been associated with lesser prevalence and severity of fatigue. Studies are needed, however, to test if antioxidant-rich diets could improve fatigue. METHODS: Pilot, randomized, trial conducted between January 2014 and April 2015, to investigate if a 3-month diet rich in fruit, vegetables, whole grains, and omega-3 fatty acid-rich foods, named the fatigue reduction diet (FRD), improved fatigue and sleep compared to an attention control, named the general health curriculum (GHC)...

PURPOSE: There is still a considerable percentage of hereditary breast and ovarian cancer (HBOC) cases not explained by BRCA1 and BRCA2 genes. In this report, next-generation sequencing (NGS) techniques were applied to identify novel variants and/or genes involved in HBOC susceptibility. METHODS: Using whole exome sequencing, we identified a novel germline mutation in the moderate-risk gene ATM (c.5441delT; p.Leu1814Trpfs*14) in a family negative for mutations in BRCA1/2 (BRCAX)...

PURPOSE: Interaction between immune-regulatory proteins and tumor infiltrating lymphocytes (TILs) is complex, and their associations may have significant clinical implications. This study was designed to evaluate the relationships between immunomodulatory proteins and TIL subsets and their impact on prognosis in breast cancer. METHODS: 377 invasive breast cancer cases were selected, and immunohistochemistry was performed for HLA-A, HLA-ABC, and indoleamine 2,3-dioxygenase (IDO); CD4+, CD8+, and FOXP3+ T cells were counted in intratumoral and stromal areas for both absolute numbers as well as their ratios...

PURPOSE: Aryl hydrocarbon receptor (AhR) inhibits estrogen receptor (ER) pathway, which may suppress estrogen-dependent cell proliferation. However, the correlation between AhR stimulation and intratumoral estrogen synthesis, especially through aromatase, has not been reported to date. In the present study, we examined this correlation in breast cancer cells. METHODS: We examined AhR and aromatase immunoreactivity in 29 patients with invasive ductal carcinoma. We performed in vitro studies using three breast carcinoma cell lines, MCF-7, T47D, and MDA-MB-231...

PURPOSE: To investigate the discordance between original and central laboratories in estrogen receptor (ER) status, in tumors originally deemed to be ER-negative, and in HER2 status in a diverse population-based sample. METHODS: In a follow-up study of 1785 women with Stage I-III breast cancer diagnosed between 2005 and 2007 in the Detroit and Los Angeles County SEER registry catchment areas, participants were asked to consent to reassessment of ER (in tumors originally deemed to be ER-negative) and HER2 status on archival tumor samples approximately four years after diagnosis...

PURPOSE: The current American Joint Committee on Cancer (AJCC) staging manual uses tumor size, lymph node, and metastatic status to stage breast cancer across different subtypes. We examined the prognosis of triple-negative breast cancer (TNBC) versus non-TNBC within the same stages and sub-stages to evaluate whether TNBC had worse prognosis than non-TNBC. METHODS: We reviewed the National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) data and identified 158,358 patients diagnosed with breast cancer from 2010 to 2012...

PURPOSE: Triple-negative breast cancer (TNBC) has aggressive characteristics and fewer treatment options than other subtypes. The purpose of this study was to explore prognostic biomarkers for TNBC that can be easily detected from the blood samples. METHODS: MDA-MB-231 and MDA-MB-231BR, a brain metastatic variant of the human TNBC cell line MDA-MB-231, were used as less and more aggressive models of TNBC, respectively. The extent to which the candidate gene/protein identified by RNA sequencing correlated well with aggressiveness of TNBC and how much protein was detected from the blood of tumor-bearing mice were evaluated...

PURPOSE: Neoadjuvant chemotherapy (NCT) plus anti-HER2 agents are the standard of care for locally advanced HER2-positive breast cancer. The aim of this study was to evaluate the prevalence and prognostic impact of HER2 loss in patients with HER2-positive disease treated with neoadjuvant therapy with or without trastuzumab. METHODS: 549 consecutive HER2-positive patients were included in this study. 379 patients were treated with paclitaxel, carboplatin, and trastuzumab (PCH cohort) and 170 were treated with paclitaxel and carboplatin only (PC cohort)...

PURPOSE: Electrochemotherapy (ECT) is the application of electric pulses to tumour tissue to render the cell membranes permeable to usually impermeant hydrophilic anti-cancer drugs, thereby enhancing cytotoxic effects. We sought to ascertain whether ECT can be an effective palliative treatment for cutaneous metastases of breast cancer. METHODS: This work reports data from the European Standard Operating Procedures for Electrochemotherapy trial (EudraCT Number: 2004-002183-18)...

PURPOSE: We examined acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) events among 9679 women treated for breast cancer on four adjuvant Alliance for Clinical Trials in Oncology trials with >90 months of follow-up in order to better characterize the risk for AML/MDS in older patients receiving anthracyclines. METHODS: We used multivariable Cox regression to examine factors associated with AML/MDS, adjusting for age (≥65 vs. <65 years; separately for ≥70 vs...

PURPOSE: Mammographic density is a measurable and modifiable biomarker that is strongly and independently associated with breast cancer risk. Paradoxically, although Asian women have lower risk of breast cancer, studies of minority Asian women in predominantly Caucasian populations have found that Asian women have higher percent density. In this cross-sectional study, we compared the distribution of mammographic density for a matched cohort of Asian women from Malaysia and Caucasian women from Sweden, and determined if variations in mammographic density could be attributed to population differences in breast cancer risk factors...

PURPOSE: In certain ductal carcinoma in situ (DCIS) subpopulations, there is no consensus regarding whether to postoperatively irradiate; decisions are often made based on potential risk of cardiac toxicities. Given the utility of Surveillance, Epidemiology, and End Results (SEER) data for studying cardiac mortality in invasive disease, this is the first such study specific for DCIS patients, evaluating trends in cardiac mortality after left-sided radiotherapy (RT). METHODS: The SEER database was queried for patients with DCIS that received RT and had known unilaterality...

PURPOSE: Certain peptide hormones and/or their cognate receptors influencing normal cellular pathways also have been detected in breast cancers. The hypothesis is that gene subsets of these regulatory molecules predict risk of breast carcinoma recurrence in patients with primary disease. METHODS: Gene expression levels of 61 hormones and 81 receptors were determined by microarray with LCM-procured carcinoma cells of 247 de-identified biopsies. Univariable and multivariable Cox regressions were determined using expression levels of each hormone/receptor gene, individually or as a pair...

PURPOSE: Breast cancers have a poorer prognosis if estrogen receptor expression was lost during recurrence. It is unclear whether this conversion is cell autonomous or whether it can be promoted by the microenvironment during cancer dormancy. We explored the ability of marrow-derived stromal cell lines to arrest co-cultured breast cancer cells and suppress estrogen receptor alpha (ER) expression during arrest, facilitating the emergence of estrogen-independent breast cancer clones. METHODS: Cancer cell growth, ER protein, microRNA, and mRNA levels were measured in breast cancer cell lines exposed to conditioned medium from marrow stromal lines in the presence and absence of estrogen and of signaling pathway modulators...

PURPOSE: Genome-wide association studies (GWAS) have identified dozens of single-nucleotide polymorphisms (SNPs) associated with breast cancer. Few studies focused on young-onset breast cancer, which exhibits etiologic and tumor-type differences from older-onset disease. Possible confounding by prenatal effects of the maternal genome has also not been considered. METHODS: Using a family-based design for breast cancer before age 50, we assessed the relationship between breast cancer and 77 GWAS-identified breast cancer risk SNPs...

PURPOSE: While triple-negative breast cancer (TNBC) is negative for estrogen receptor alpha, a substantial proportion of carcinomas express estrogen receptor beta (ERβ); consequently, estrogen actions and metabolism may be relevant in this cancer subtype. METHODS: A cohort of 81 TNBC patients from Tohoku University Hospital, Japan were characterised with regard to the expression of estrogen receptor beta and enzymes known to modulate levels of estrogens in breast and other tissues (Aromatase, 17-beta- Hydroxysteroid dehydrogenases 1, 2 and 6)...

BACKGROUND: U.S. Hispanic women have high rates of parity, breastfeeding, and obesity. It is unclear whether these reproductive factors are associated with breast cancer (BC) mortality. We examined the associations between breastfeeding, parity, adiposity and BC-specific and overall mortality in Hispanic and non-Hispanic white (NHW) BC cases. METHODS: The study population included 2921 parous women (1477 Hispanics, 1444 NHWs) from the Breast Cancer Health Disparities Study with invasive BC diagnosed between 1995 and 2004...
