PURPOSE An open-label, phase II study to evaluate progression-free survival (PFS), overall best response, adverse events (AEs), and patient-reported outcomes with sorafenib versus interferon alfa-2a (IFN-alpha-2a) in patients with untreated, advanced renal cancer. PATIENTS AND METHODS A total of 189 patients were randomly assigned to oral sorafenib 400 mg(More)
PURPOSE In patients with acute leukemias, a lymphoid phenotype, the presence of a Philadelphia chromosome (Ph), and inadequate central nervous system (CNS)-directed prophylactic therapy are risk factors for CNS involvement. Imatinib mesylate has promising single-agent antileukemic activity in patients with advanced Ph(+) acute leukemias. It was the aim of(More)
Adult patients with acute lymphoblastic leukemia (ALL) who are stratified into the standard-risk (SR) group due to the absence of adverse prognostic factors relapse in 40% to 55% of the cases. To identify complementary markers suitable for further treatment stratification in SR ALL, we evaluated the predictive value of minimal residual disease (MRD) and(More)
The German Multicenter Study Group for Adult ALL (GMALL) conducts since 1984 trials with risk adapted study design. The model of conventional prognostic factors comprises now WBC, age, immunophenotype, cytogenetics and molecular genetics. Risk stratification according to these factors allows a highly significant prediction of relapse risk in adult ALL. In(More)
In adult Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL), minimal residual disease (MRD) after stem cell transplantation (SCT) is associated with a relapse probability exceeding 90%. Starting imatinib in the setting of MRD may decrease this high relapse rate. In this prospective multicenter study, 27 Ph+ ALL patients received(More)
The Abl kinase inhibitor imatinib mesylate (STI571) has significant and rapid antileukemic activity in Philadelphia chromosome/Bcr-Abl-positive acute lymphoblastic leukemia (Ph(+) ALL) but such activity is usually of short duration except for a small proportion of patients. To determine the prognostic significance of early Bcr-Abl levels and changes in(More)
Imatinib has marked antileukemic activity in advanced Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ALL), but secondary resistance develops rapidly, reflecting the limitations of single-agent therapy. Experimental data suggest that interferon-alpha (IFN-alpha) enhances the antileukemic activity of imatinib. We therefore examined combined(More)
OBJECTIVE Characterization of the effects of infection with HIV-1 on cellular gene expression. DESIGN AND METHODS Differential RNA display was applied to compare uninfected and HIV-1LAI-infected CEM cells 24 h post-inoculation. Differential bands were selected, cloned and several clones per band were sequenced. RNase protection assay was used to confirm(More)
Imatinib has pronounced antileukemic activity in Ph+ALL, although responses are usually short. To determine whether imatinib may facilitate allogeneic SCT in relapsed or refractory Ph+ALL, we evaluated 46 consecutive, not previously transplanted patients who were enrolled in phase II studies of imatinib. Of 30 patients eligible for SCT, 22 (73%) were(More)
CD8(+)CD28(-) T cells have been characterized by oligoclonal expansions, impaired proliferative responses, but preserved cytotoxicity and reduced telomeres. To examine this subset further and define the underlying mechanisms of proliferation arrest, we investigated several features of this cell type compared with CD8(+)CD28(+) controls. We analyzed(More)
