Viral-based techniques are the most efficient systems to deliver DNA into stem cells because they show high gene transduction and transgene expression in many cellular models. However, the use of viral vectors has several disadvantages mainly involving safety risks. Conversely, nonviral methods are rather inefficient for most primary cells. The Nucleofector(More)
Indoleamine 2,3-dioxygenase (IDO) is a novel immunosuppressive agent expressed in some subsets of normal and neoplastic cells, including acute myeloid leukemia (AML) cells. Here, we show that IDO expression correlates with increased circulating CD4+CD25+FOXP3+ T cells in patients with AML at diagnosis. In vitro, IDO+ AML cells increase the number of CD4+(More)
BACKGROUND AND OBJECTIVES The aim of this study was to evaluate the efficacy of pegfilgrastim, in combination with salvage chemotherapy, in mobilizing CD34(+) stem cells into the peripheral blood of pretreated lymphoma patients. DESIGN AND METHODS This was an open-label phase II study including 25 pretreated patients (Hodgkin's disease=4; aggressive(More)
Antibody-targeted chemotherapy is a promising approach in patients with hematological malignancies. In particular, gemtuzumab ozogamicin (GO, formerly CMA-676), an anti-CD33 antibody linked to calicheamicin, has been approved for the treatment of elderly patients with acute myeloid leukemia (AML) in relapse. Nevertheless, no data are until now available(More)
Thirteen patients with acute myeloid leukemia, 5 with active disease, 2 in molecular relapse, and 6 in morphologic complete remission (CR; median age, 62 years; range, 53-73 years) received highly purified CD56(+)CD3(-) natural killer (NK) cells from haploidentical killer immunoglobulin-like receptor-ligand mismatched donors after(More)
The myelodysplastic syndromes (MDS) are characterized by hemopoietic insufficiency associated with severe cytopenias, leading to serious morbidity, and acute leukemia development. MDS typically occur in elderly people, with a median age at diagnosis ranging between 60 and 75 years. The patients' prognosis, estimated according to the International Prognostic(More)
We designed a phase 1-2 study to evaluate the safety and the efficacy of increasing doses of bendamustine (160 mg/m², 180 mg/m², and 200 mg/m² given on days -7 and -6) coupled with fixed doses of etoposide, cytarabine, and melphalan (BeEAM regimen) as the conditioning regimen to autologous stem cell transplantation for resistant/relapsed lymphoma patients.(More)
We evaluated the toxicity and efficacy of nonpegylated liposomal doxorubicin (Myocet) when substituted for conventional doxorubicin in the CHOP-21 regimen in the treatment of frail elderly patients with aggressive non-Hodgkin lymphoma. Twenty frail patients (median age, 73 years), as defined by Balducci et al., with diffuse large B cell or grade IIIb(More)
Contribution: L.T.v.d.M. performed experiments, analyzed and interpreted data, and wrote the manuscript; E.W. designed and performed the genomic analysis; M.L. performed research; H.V. performed in silico structure analysis; D.R. performed research; J.B. and C.L. performed drug monitoring and designed research; R.J.B. performed the pharmacokinetic studies;(More)
We applied Charlson comorbidity index (CCI) stratification on a large cohort of chronic myeloid leukemia (CML) very elderly patients (>75 years) treated with imatinib, in order to observe the impact of concomitant diseases on both compliance and outcome. One hundred and eighty-one patients were recruited by 21 Italian centers. There were 95 males and 86(More)
