Despite progress in leukemia therapy, most children who experience relapse have a dismal prognosis. New, effective approaches are needed. We conducted a phase 1 study of a novel nucleoside analog, clofarabine, in pediatric patients with refractory and relapsed leukemia. Clofarabine was infused intravenously over 1 hour each day for 5 days. Six dose levels,(More)
BACKGROUND Adult Burkitt-type lymphoma (BL) and acute lymphoblastic leukemia (B-ALL) are rare entities composing 1% to 5% of non-Hodgkin lymphomas NHL) or ALL. Prognosis of BL and B-ALL has been poor with conventional NHL or ALL regimens, but has improved with dose-intensive regimens. METHODS To evaluate the addition of rituximab, a CD20 monoclonal(More)
We reviewed the outcome of 671 patients 65 years of age or older with newly diagnosed acute myeloid leukemia (AML) treated at our institution between 2000 and 2010 with intensive chemotherapy (n = 557) or azacitidine- or decitabine-based therapy (n = 114). Both groups were balanced according to cytogenetics and performance status. The complete response(More)
BACKGROUND Hypomethylating agents have demonstrated activity in patients with myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). Preclinical and single-arm trials have suggested that adding histone deacetylase (HDAC) inhibitors may synergize the epigenetic modulation of hypomethylating agents and improve treatment results. METHODS The(More)
PURPOSE To evaluate the safety and efficacy of the combination of the histone deacetylase inhibitor vorinostat with idarubicin and ara-C (cytarabine) in patients with acute myelogenous leukemia (AML) or myelodysplastic syndrome (MDS). PATIENTS AND METHODS Patients with previously untreated AML or higher-risk MDS age 15 to 65 years with appropriate organ(More)
We investigated efficacy and safety of rabbit anti-thymocyte globulin (rATG), cyclosporine and granulocyte colony-stimulating factor (G-CSF) as first-line therapy for patients with aplastic anemia (AA) and low or intermediate-1 or hypoplastic myelodysplastic syndrome (MDS). rATG 3.5 mg/kg (or 2.5 mg/kg per day for patients >or=55 years with MDS) was given(More)
This report describes the final results of a Phase II clinical trial investigating the efficacy of rabbit antithymocyte globulin (rATG), ciclosporin, steroids, and granulocyte colony-stimulating factor (GCSF) in patients with untreated aplastic anaemia (AA), or low to intermediate-risk and hypocellular myelodysplastic syndrome (MDS). We treated 24 patients(More)
BACKGROUND IDH1 and IDH2 gene mutations are novel, recurring molecular aberrations among patients with normal karyotype acute myeloid leukemia (AML). METHODS Among 358 patients with AML treated on 4 protocols using high-dose ara-C plus idarubicin induction, pretreatment samples were available for 170 (median age 53 years, [range, 17-73]; 96% ≤65) and were(More)
The clinical characteristics, treatment options and outcomes in patients with acute promyelocytic leukaemia (APL) and hyperleucocytosis remain poorly defined. This study reviewed 242 consecutive patients with APL; 29 patients (12%) had a white blood cell count (WBC) ≥ 50 × 10(9) /l at presentation (median WBC 85·5 × 10(9) /l). Patients with(More)
PURPOSE To determine the efficacy and toxicity of the combination of sorafenib, cytarabine, and idarubicin in patients with acute myeloid leukemia (AML) younger than age 65 years. PATIENTS AND METHODS In the phase I part of the study, 10 patients with relapsed AML were treated with escalating doses of sorafenib with chemotherapy to establish the feasibility(More)
