The Undervalued Effects of Polychlorinated Biphenyl Exposure on Breast Cancer.

The incidence of breast cancer across the world has been on the rise in recent decades. Because identified risk factors can only explain a relatively small portion of the cases, environmental exposure to organic pollutants is suspected to play a role in breast cancer etiology. Polychlorinated biphenyls (PCBs) are among the most abundant pollutants, and the impact of their exposure on breast cancer risk has been extensively studied in recent decades. However, the results of most epidemiologic studies do not ...

PD-L1 Acts as a Promising Immune Marker to Predict the Response to Neoadjuvant Chemotherapy in Breast Cancer Patients.

Programmed death ligand 1 (PD-L1) is a negative immune stimulatory molecule that plays a key role in tumor immune escape. We analyzed the clinical value of PD-L1-positive expression in predicting the outcome of breast cancer patients and to establish its role as new biomarker to guide precise treatment.

Efficacy of Neoadjuvant Endocrine Therapy Versus Neoadjuvant Chemotherapy in ER-positive Breast Cancer: Results From a Prospective Institutional Database.

Although neoadjuvant chemotherapy (NACT) has been established as a standard for medically fit patients with locally advanced breast cancer, there has been renewed interest in utilizing neoadjuvant endocrine therapy (NET) for women with estrogen receptor-positive, human epidermal growth factor receptor 2-negative breast cancer. Rates of pathologic complete response (pCR) are known to be low, but data regarding down-staging and long-term outcomes are inconsistent.

Radiotherapy After Skin-Sparing Mastectomy and Implant-Based Breast Reconstruction.

We evaluated the cosmetic results of radiotherapy (RT) after implant-based reconstruction (IBR).

Do Decreased Breast Microcalcifications After Neoadjuvant Chemotherapy Predict Pathologic Complete Response?

Clinical response evaluation by image examination after neoadjuvant chemotherapy for breast cancer is important for determining drug response and progression. Mammography is less correlated with pathologic response assessment than magnetic resonance imaging or ultrasonography. The present study clarified characteristics of breast cancer patients with decreased microcalcifications after neoadjuvant chemotherapy to increase the accuracy of mammographic assessment.

Low Plasma IL-8 Levels During Chemotherapy Are Predictive of Excellent Long-Term Survival in Metastatic Breast Cancer.

Interleukin (IL)-8 is a proinflammatory cytokine, and high levels of IL-8 are associated with poor prognosis in many malignancies. The objective of this study was to explore the clinical benefit of monitoring plasma IL-8 levels during breast cancer chemotherapy.

Impact of Implementing B-RST to Screen for Hereditary Breast and Ovarian Cancer on Risk Perception and Genetic Counseling Uptake Among Women in an Academic Safety Net Hospital.

Lower socioeconomic status is strongly associated with decreased perception of cancer risk. Fewer low socioeconomic status women than expected currently access cancer genetic services from which they may benefit.

Germline Genetic Variants in GATA3 and Breast Cancer Treatment Outcomes in SWOG S8897 Trial and the Pathways Study.

GATA3 is a critical transcription factor in maintaining the differentiated state of luminal mammary epithelial cells. We sought to determine the prognostic and predictive roles of GATA3 genotypes for breast cancer.

A Reappraisal of the Comparative Effectiveness of Lumpectomy Versus Mastectomy on Breast Cancer Survival: A Propensity Score-Matched Update From the National Cancer Data Base (NCDB).

Recent observational studies are concerning because they document rising mastectomy rates coinciding with more than a dozen reports that lumpectomy has better overall survival (OS) than mastectomy. Our aim was to determine if there were differences in OS of matched breast cancer patients undergoing lumpectomy versus mastectomy in the National Cancer Database (NCDB).

Factors Determining Anthracycline Use in Hormone Receptor Positive, Early-Stage Breast Cancer.

Anthracyclines are associated with significant toxicities whereas nonanthracyclines have proven to be better tolerated. A 21-gene assay allows clinicians to predict who will not benefit from adjuvant chemotherapy and avoid systemic toxicities. Physicians are using the recurrence score to guide chemotherapy selection, despite the lack of evidence. In this study we examined factors associated with prescribing patterns for an anthracycline-based chemotherapy in hormone receptor-positive stage I to III breast c...

The Results of Surveillance Imaging After Breast Conservation Surgery and Partial Breast Reconstruction With Chest Wall Perforator Flaps; A Qualitative Analysis Compared With Standard Breast-Conserving Surgery for Breast Cancer.

Partial breast reconstruction (PBR) using chest wall perforator flaps (CWPF) allows for excision of tumors in the outer quadrant of the breast in women with small to moderate non-ptotic breasts resulting in a good aesthetic outcome. There are limited data available in the literature regarding long-term follow-up and the effect of CWPF on subsequent surveillance mammographic interpretation and recall rates. A retrospective audit with qualitative analysis of initial mammograms was performed to assess this.

A Better Pathway? Building Consensus and Engaging Providers with Feedback to Improve and Standardize Cancer Care.

Unwanted clinical variation is common across the United States health care system and is particularly vexing in oncology owing to the complexity, morbidity, and high cost of the disease. Efforts to standardize care including guidelines and continuing medical education have had only limited impact. Disease-specific oncology clinical pathways hold the promise of reducing variation but have been hampered by a lack of ownership and accountability among oncology providers.

Examining Associations of Racial Residential Segregation With Patient Knowledge of Breast Cancer and Treatment Receipt.

The effect of racial residential segregation on breast cancer treatment disparities is unclear. We examined whether racial segregation is associated with adjuvant treatment receipt and patient knowledge of disease.

A New Genetic Risk Score to Predict the Outcome of Locally Advanced or Metastatic Breast Cancer Patients Treated With First-Line Exemestane: Results From a Prospective Study.

Approximately 50% of locally advanced or metastatic breast cancer (MBC) patients treated with first-line exemestane do not show objective response and currently there are no reliable biomarkers to predict the outcome of patients using this therapy. The constitutive genetic background might be responsible for differences in the outcome of exemestane-treated patients. We designed a prospective study to investigate the role of germ line polymorphisms as biomarkers of survival.

Metabolic Characterization of Inflammatory Breast Cancer With Baseline FDG-PET/CT: Relationship With Pathologic Response After Neoadjuvant Chemotherapy, Receptor Status, and Tumor Grade.

The aim of this study was to determine if, in inflammatory breast cancer (IBC), baseline metabolic activity (maximum standardized uptake value [SUVmax]) of primary tumor and involved regional lymph nodes (IRLN) are prognostic markers of response after neoadjuvant systemic therapy (NAS).

Detection of HER2-positive Circulating Tumor Cells Using the LiquidBiopsy System in Breast Cancer.

Most previous studies of circulating tumor cells (CTCs) are based on the CellSearch platform, but CellSearch has a number of limitations. This study aimed to use the LiquidBiopsy system and immunofluorescence to test the human epidermal growth factor receptor 2 (HER2) status of CTCs in patients with breast cancer.

Impact of Chemotherapy-induced Menopause in Women of Childbearing Age With Non-metastatic Breast Cancer - Preliminary Results From the MENOCOR Study.

Young patients with breast cancer treated with chemotherapy can experience ovarian failure, which can lead to chemotherapy-induced menopause (CIM) impacting the quality of life (QoL). A prospective study was set out to evaluate the impact of CIM on QoL in women of childbearing age with non-metastatic breast cancer, and this article reports results of the interim analysis conducted to evaluate feasibility and to see preliminary results.
