PURPOSE The primary goal of this trial was to determine the response rate of single-agent vorinostat in patients with metastatic breast cancer. The secondary goals included assessment of time to progression, evaluation of toxicities, and overall survival. EXPERIMENTAL DESIGN From June 2005 to March 2006, 14 patients received vorinostat, 200 mg p.o., twice(More)
In preclinical models, the histone deacetylase inhibitor vorinostat sensitizes breast cancer cells to tubulin-polymerizing agents and to anti-vascular endothelial growth factor-directed therapies. We sought to determine the safety and efficacy of vorinostat plus paclitaxel and bevacizumab as first-line therapy in metastatic breast cancer (MBC), and the(More)
INTRODUCTION This study evaluated the association between aromatase inhibitor (AI) therapy and cognitive function (over a 6-month period) in a cohort of patients aged ≥ 60 years compared with an age-matched healthy control group, and it evaluated changes in regional cerebral metabolism as measured by positron emission tomography (PET) scans of the brain(More)
Cancer stem cells (CSC) play critical roles in cancer initiation, progression, and therapeutic refractoriness. Although many studies have focused on the genes and pathways involved in stemness, characterization of the factors in the tumor microenvironment that regulate CSCs is lacking. In this study, we investigated the effects of stromal fibroblasts on(More)
BACKGROUND Pathologic complete response (pCR) to neoadjuvant chemotherapy (NCT) is considered a surrogate for improved survival. Platinum-containing NCT, particularly in patients with HER2+ and triple-negative breast cancers (TNBC) may increase pCR rates. METHODS Tumor characteristics, pCR rates (no invasive disease in breast and lymph nodes), toxicities,(More)
Metaplastic breast cancer (MBC) is a rare histologic subtype needing further characterization. The aim of our study was to compare MBC to infiltrating ductal carcinoma (IDC) of the breast and to identify demographic, clinicopathologic, treatment, and survival differences. MBC and IDC patients were identified using the Surveillance, Epidemiology, and End(More)
As tyrosine kinase inhibitors have been associated with cardiotoxicity, we evaluated the effect of pazopanib, an inhibitor of vascular endothelial growth factor receptor, platelet-derived growth factor receptor, and c-Kit, on electrocardiographic parameters in patients with cancer. This double-blind, placebo-controlled, parallel-group study randomized(More)
Background Genetic abnormalities in cell cycle control are common in malignant melanoma. UCN-01 (7-hydroxystaurosporine) is an investigational agent that exhibits antitumor activity by perturbing the cancer cell cycle. A patient with advanced melanoma experienced a partial response in a phase I trial of single agent UCN-01. We sought to determine the(More)
PURPOSE We investigated the efficacy and toxicity of sorafenib, a multikinase inhibitor of vascular endothelial growth factor receptor tyrosine kinase, in combination with vinorelbine therapy in a phase I/II trial in patients with metastatic breast cancer. PATIENTS AND METHODS We enrolled 11 patients in the phase I portion to determine the maximum(More)
The aim of this study is to investigate the efficacy of combining a histone deacetylase inhibitor (LBH589) and a breast cancer stem cells (BCSC)-targeting agent (salinomycin) as a novel combination therapy for triple-negative breast cancer (TNBC). We performed in vitro studies using the TNBC cell lines to examine the combined effect. We used the mammosphere(More)
