CONTEXT For the treatment of a single metastasis to the brain, surgical resection combined with postoperative radiotherapy is more effective than treatment with radiotherapy alone. However, the efficacy of postoperative radiotherapy after complete surgical resection has not been established. OBJECTIVE To determine if postoperative radiotherapy resulted in(More)
Carcinoembryonic antigen (CEA) is expressed in a wide variety of adenocarcinomas, and it is well recognized that cancer patients are immunologically "tolerant" to CEA. The purpose of this study was to determine whether we could break immune tolerance to CEA by vaccinating patients with a monoclonal anti-idiotype antibody that is the internal image of CEA(More)
Interleukin-15 (IL-15) has a major role in NK-cell homeostasis. Modulation of the relative frequency and expression intensity of the NK-cell receptors by IL-15 may increase NK cell-mediated cytotoxicity in cancer patients. We investigated the receptor repertoire and measured NK-cell activity in newly diagnosed AML patients and evaluated the ex vivo effects(More)
The epidermal growth factor receptor (EGFR) is a transmembrane glycoprotein, with an extracellular ligand-binding domain and intracellular tyrosine kinase domain. Ligand binding induces EGFR dimerization and autophosphorylation on several tyrosine residues in the intracellular domain, leading to mitogenic signal transduction. EGFR overexpression correlates(More)
Human anti-murine immunoglobulin responses were assessed in serum from three groups of patients receiving murine monoclonal antibody therapy. Each of the three patient groups responded differently. Chronic lymphocytic leukemia patients demonstrated little or no preexisting murine immunoglobulin G-reactive antiglobulin prior to treatment, while the cutaneous(More)
Immunization with anti-idiotype (Id) antibodies represents a novel new approach to active immunotherapy. Extensive studies in animal tumor models have demonstrated the efficacy of anti-Id vaccines in preventing tumor growth and curing mice with established tumor. We have developed and characterized several murine monoclonal anti-Id antibodies (Ab2) which(More)
We performed a phase II study of belinostat in patients with acute myeloid leukemia (AML). In this open label phase II study (NCT00357032), patients with relapsed/refractory AML, or newly diagnosed patients with AML over the age of 60, were eligible. Belinostat was administered intravenously (IV) at a dose of 1000 mg/m(2) daily on days 1-5 of a 21-day cycle(More)
Important advances in molecular biology and chelation chemistry have led to new and improved monoclonal antibody reagents. Rituximab (IDEC-C2B8) was approved by the United States Food and Drug Administration for relapsed CD20-positive lymphomas, and denileukin diftitox was approved (DAB389IL-2) for CTCL. Ibritumomab tiuxetan and iodine 131 anti-B1 have(More)
