BACKGROUND Phase 2 trials suggest that prolonged intravenous (IV) infusion of the topoisomerase 1 inhibitor topotecan may be less toxic than when given by standard IV bolus 5-day administration. Oxaliplatin exhibits efficacy in platinum-pretreated disease and shows preclinical synergy with topoisomerase 1 inhibitors. We sought to determine the efficacy and(More)
PURPOSE The protein encoded by N-myc downstream-regulated gene 1 (NDRG1) is a recently discovered protein whose transcription is induced by androgens and hypoxia. We hypothesized that NDRG1 expression patterns might reveal a biological basis for the disparity of clinical outcome of prostate cancer patients with different ethnic backgrounds. EXPERIMENTAL(More)
PURPOSE The purpose is to investigate the clinical relevance of altered patterns of p27 and Skp2 expression in African-American patients with localized prostate cancer. The abundance of p27, an inhibitor of cell proliferation, is controlled by Skp2-dependent proteolysis. EXPERIMENTAL DESIGN A well-characterized cohort of 162 African-Americans who(More)
PURPOSE Neutral endopeptidase (NEP) is a cell-surface peptidase that inactivates neuropeptide growth factors implicated in prostate cancer progression. The clinical significance of decreased NEP expression observed in prostate cancer is unclear. We investigated whether decreased NEP expression in localized prostate cancers is associated with(More)
OBJECTIVE Imatinib mesylate (IM, Gleevec), a potent PDGF/PDGFR tyrosine kinase inhibitor, affects stroma and vascular endothelial cells. Our study sought to determine the safety and activity of paclitaxel with an intermittent schedule of IM. MATERIALS AND METHODS rEOC patients previously treated with platinum/paclitaxel and ≤2 regimens for recurrence were(More)
266 Background: Addition of erlotinib (E) to gemcitabine (G) results in improved OS for patients (pts) with advanced pancreatic cancer. Many pancreatic tumors have constitutively activated ras/raf pathways and overexpress VEGF. Sorafenib (S), a multitargeted tyrosine kinase inhibitor, including VEGR 1-3, PDGFR-α and β and the RAF/MEK/ERK pathway, when(More)
Malakoplakia is a distinctive type of histiocytic inflammatory reaction that occurs most commonly in the urinary tract and is usually due to infection by coliform bacteria. A 68-year-old woman developed a pathologic fracture of the right femoral neck secondary to malakoplakia of bone. The patient had received multiagent chemotherapy for a malignant lymphoma(More)
Abdominal tissue, serum, and bile samples were obtained from 37 patients given a single, 2-g intravenous infusion of aztreonam immediately prior to an elective abdominal operation. Samples were obtained at 0 to 6 h after dosing. Mean concentrations in tissues and fluids and specimen/serum rations are reported. Levels in tissue and bile exceeded the reported(More)
12007 Background: B inhibits proteasome function and may be synergistic in causing apoptotic death with platinum agents. We were interested in combining B with OX but concerned with dose limiting (DL) NT based on our prior B phase I study [Hamilton et al., JCO 2005]: therefore this Phase I dose-escalation study (alternating increases of B and OX) focusing(More)
