PURPOSE Imatinib mesylate, a specific Bcr-Abl tyrosine kinase inhibitor, has shown encouraging activity in chronic myelogenous leukemia (CML). EXPERIMENTAL DESIGN We treated 237 patients (median age, 50 years; age range, 18-82 years) with Philadelphia chromosome (Ph)-positive accelerated-phase CML with oral imatinib mesylate at daily doses of 400 mg (26(More)
We evaluated demographic characteristics and graft composition as risk factors for acute graft-versus-host disease (GVHD) in 160 adult recipients of HLA-identical allogeneic blood stem cell transplants. The patients received a median nucleated cell dose of 7.9 x 10(8)/kg and median C34(+) cell dose of 5.6 x 10(6)/kg. GVHD prophylaxis consisted of(More)
Axonal injury is consistently observed after traumatic brain injury (TBI). Prior research has extensively characterized the post-TBI response in myelinated axons. Despite evidence that unmyelinated axons comprise a numerical majority of cerebral axons, pathologic changes in unmyelinated axons after TBI have not been systematically studied. To identify(More)
Chronic myelomonocytic leukemia (CMML) is a hematologic malignancy characterized by wide heterogeneity of clinical presentation and course. CMML shares myelodysplastic characteristics with features of myeloproliferative disorders. No treatment has proven effective in modifying the natural course of the disease. To improve the prognostic assessment of(More)
Six hundred nineteen patients with metastatic breast cancer, treated with a combination of 5-fluorouracil, Adriamycin, and cyclophosphamide, or close variations of this program, with or without immunotherapy were analyzed retrospectively to identify those host, tumor, or treatment characteristics that might be of prognostic importance in predicting response(More)
PURPOSE Aberrant methylation of promoter-associated CpG islands is an epigenetic oncogenic mechanism. The objective of this study was to define the methylation characteristics of patients with acute lymphocytic leukemia (ALL). EXPERIMENTAL DESIGN Using bisulfite-PCR followed by restriction enzyme digestion (COBRA), we have analyzed the methylation status(More)
Univariate and multivariate analyses were conducted on data collected from the records of 619 patients with metastatic breast cancer in whom an Adriamycin-containing chemotherapeutic regimen was used. Using a forward, stepwise logistic regression procedure, several models or equations in which a small number of pretreatment factors were incorporated were(More)
PURPOSE Paclitaxel has significant antitumor activity in patients with metastaticbreast cancer who have been previously treated with or exposed to anthracycline-containing chemotherapy. In this prospective randomized trial, the role of paclitaxel was evaluated in an adjuvant setting to determine its impact on reducing the risk of recurrence in patients with(More)
The Akt/mammalian target of rapamycin (mTOR)/4E-BP1 pathway is considered to be a central regulator of protein synthesis, involving the regulation of cell proliferation, differentiation, and survival. The inhibitors of mTOR as anticancer reagents are undergoing active evaluation in various malignancies including breast cancer. However, the activation status(More)
Previous studies have characterized the reactivity of CD8+ CTLs with ovarian and breast cancer. There is little information about the antigens and epitopes recognized by CD4+ T cells in these patients. In this study, we analyzed the ability of T cells from peripheral blood mononuclear cells of breast cancer patients to recognize HER-2/neu (HER-2) peptides.(More)
