Allelic variants of the MDR-1 gene have been shown recently to influence protein expression and P-glycoprotein (P-gp) function in healthy volunteers. Therefore, 405 acute myeloid leukemia patients were investigated for somatic genotypes of the three most frequent single nucleotide polymorphisms (SNPs) in exons 12, 21, and 26. In all three loci, homozygous(More)
Mitoxantrone, a cytotoxic anthracenedione derivative, has given clinical evidence of beneficial activity in breast cancer, lymphoma and leukaemia. Several different mechanisms of action have been suggested to account for this. In addition to intercalation, biological effects such as electrostatic interactions with DNA, DNA-protein cross-links,(More)
We present an analysis of prognostic factors derived from a trial in patients with acute myeloid leukemia older than 60 years. The AML96 trial included 909 patients with a median age of 67 years (range, 61-87 years). Treatment included cytarabine-based induction therapy followed by 1 consolidation. The median follow-up time for all patients is 68 months(More)
Imatinib mesylate (STI571) is a very effective treatment option for Ph(+) chronic myeloid leukemia (CML) in chronic phase. Secondary treatment failures have mostly been observed in patients with advanced stages of disease. We report the case of a patient who unexpectedly experienced blast crisis of the central nervous system although having achieved(More)
Culture-based preemptive therapy with ganciclovir was shown to reduce the incidence of cytomegalovirus (CMV) disease after bone marrow transplantation (BMT). Culture techniques did not detect CMV in 12% to 13% of patients before the onset of CMV disease. In a prospective study, 71 patients either received preemptive therapy based on polymerase chain(More)
The mortality of central nervous system (CNS) aspergillosis approaches 100%, requiring improved therapies. Voriconazole gives superior efficacy and survival in invasive aspergillosis, compared with amphotericin B. Also, in contrast to other antifungal drugs, voriconazole penetrates well into the CNS. We evaluated, retrospectively, the outcome and survival(More)
BACKGROUND Cidofovir (CDV) is a nucleotide analogue with proven in vitro effects against cytomegalovirus (CMV) and adenovirus and has been successfully used in the treatment of CMV retinitis in AIDS patients. METHODS We performed a prospective study to evaluate the efficacy of CDV in 17 patients with hematological malignancies after allogeneic blood stem(More)
BACKGROUND Mycophenolate mofetil (MMF) is an inhibitor of purine nucleotide de novo synthesis leading to impaired proliferation of activated lymphocytes. Studies in animals show a synergistic effect of MMF and cyclosporine (CsA) in preventing acute graft-versus-host disease (GVHD) after allogeneic bone marrow transplantation. We performed a pilot study(More)
Between February 1998 and October 1999, 24 patients with advanced leukemia, lymphoma or solid tumors received G-CSF mobilized peripheral blood stem cells (PBSC) from HLA-matched sibling donors after dose-reduced conditioning therapy. Only patients with reduced performance status or major infectious complications, not eligible for standard transplant(More)
By simultaneous DNA staining and immunophenotyping, the aneuploid blasts of acute lymphoblastic leukemia (ALL) can be quantitated by flow cytometry. The present study evaluates the application of this method for the detection of minimal residual disease (MRD). For this purpose leukemia cells with known aneuploidy were serially diluted with diploid bone(More)
