CTLA-4 (cytotoxic T-lymphocyte antigen-4) plays a pivotal role in inhibiting T cell activation through competitive interaction with B7 molecules and interruption of costimulatory signals mediated by CD28. Polymorphisms on the CTLA-4 gene have been previously associated with autoimmune diseases, predisposition to leukemic relapse, and with graft-versus-host(More)
Immunochemotherapy with cyclophosphamide, adriamycin, vincristine, prednisone and rituximab (R-CHOP) is the standard treatment in non-immunosuppressed patients with diffuse large B-cell lymphoma (DLBCL), but its adequacy has not been definitively established in patients with human immunodeficiency virus (HIV)-related lymphoma. This phase II trial aimed to(More)
PURPOSE Fludarabine, cyclophosphamide, and mitoxantrone (FCM) results in a high response rate in previously treated patients with chronic lymphocytic leukemia (CLL). The aim of this study was to investigate FCM as frontline therapy in CLL. EXPERIMENTAL DESIGN Sixty-nine patients under the age of 65 years with active CLL were treated. Patients received six(More)
The aim of the present randomized trial was to compare high-dose therapy (HDT) with continued conventional chemotherapy in patients with multiple myeloma (MM) who responded to the initial treatment. From May 1994 to October 1999, 216 patients (122 men/94 women; stage II or III; Eastern Cooperative Oncology Group [ECOG] score less than 3) entered the study.(More)
BACKGROUND Several studies of autologous stem cell transplantation in primary refractory myeloma have produced encouraging results. However, the outcome of primary refractory patients with stable disease has not been analyzed separately from the outcome of patients with progressive disease. DESIGN AND METHODS In the Spanish Myeloma Group 2000 trial, 80(More)
BACKGROUND AND OBJECTIVE Intensive induction and post-remission therapies have improved the prognosis in adult acute lymphoblastic leukemia (ALL). However, different from children, the impact of late intensification therapy in the overall results of treatment has not been consistently evaluated. The objective of this study was to analyze the results of a(More)
Fluorescence in situ hybridization (FISH) has become a powerful technique for prognostic assessment in multiple myeloma (MM). However, the existence of associations between cytogenetic abnormalities compels us to re-assess the value of each abnormality. A total of 260 patients with MM at the time of diagnosis, enrolled in the GEM-2000 Spanish transplant(More)
BACKGROUND Purine analogs have demonstrated significant activity in patients with follicular lymphoma. The aim of this study was to analyze the efficacy and toxicity of a fludarabine combination as first-line treatment in patients with advanced-stage disease. DESIGN AND METHODS This is a phase II trial including 120 patients (< or =65 years) treated with(More)
Sixteen patients with hepatic metastases of histologically documented breast cancer were treated with etoposide (VP 16-213) and cyclophosphamide. Previously, 6 had shown relapse in the liver after adjuvant chemotherapy, 2 had failed to respond to another chemotherapy combination, and 8 had never undergone chemotherapy. Fifty percent responded to treatment,(More)
BACKGROUND AND OBJECTIVES To evaluate the impact of early and delayed consolidation chemotherapy on the outcome of children with acute lymphoblastic leukemia (ALL) stratified according to risk groups. DESIGN AND METHODS From 1989 to 1994, 195 children (< or = 15 years old) diagnosed as having ALL (ALL-L3 excluded) in 15 Spanish hospitals entered the(More)
