BACKGROUND Our objective was to determine the clinicopathologic features of triple-negative (estrogen receptor, progesterone receptor, and human epidermal growth factor-2 receptor negative) breast cancer and their relationship to obesity in women drawn from a population with one of the highest obesity rates in the United States. METHODS This retrospective study involved 620 White patients wit...
Background As a type of new targets for prognosis of malignancies, long non-coding RNA MALAT1 (metastasis-associated lung adenocarcinoma transcription 1) is associated with proliferation and metastatic abilities of several malignancies. However, its relations to development and migration of triple negative and human epidermal growth factor receptor 2 (Her-2) positive breast cancers haven't been...
Triple-negative breast cancer (TNBC) is an operational term for breast cancers lacking targetable estrogen receptor expression and HER2 amplifications. TNBC is, therefore, inherently heterogeneous, and is associated with worse prognosis, greater rates of metastasis, and earlier onset. TNBC displays mutational and transcriptional diversity, and distinct mRNA transcriptional subtypes exhibiting u...
Metaplastic Breast Cancer (MBC) is a term referring to a heterogeneous group with malignant epithelial and mesenchymal tissue components. MBC is a rare disease, accounting for 0.2% of all breast cancers. Most MBC are triple negative cancers with poor prognosis and an aggressive clinical course. Herein, we aimed to present a 74-year-old patient with metaplastic breast cancer along with clinical,...
PURPOSE To assess the prevalence of defective homologous recombination (HR)-based DNA repair in sporadic primary breast cancers, examine the clincopathologic features that correlate with defective HR and the relationship with neoadjuvant chemotherapy response. EXPERIMENTAL DESIGN We examined a cohort of 68 patients with sporadic primary breast cancer who received neoadjuvant anthracylcine-bas...
Tumors act systemically to sustain cancer progression, affecting the physiological processes in the host and triggering responses in the blood circulating cells. In this study, we explored blood transcriptional patterns of patients with two subtypes of HER2 negative breast cancers, with different prognosis and therapeutic outcome. Peripheral blood samples from seven healthy female donors and 29...
