数据说明

Conditions: Childhood Acute Lymphoblastic Leukemia in Remission, Childhood Acute Myeloid Leukemia in Remission, Childhood Chronic Myelogenous Leukemia, Childhood Myelodysplastic Syndromes, Chronic Phase Chronic Myelogenous Leukemia, de Novo Myelodysplastic Syndromes, Juvenile Myelomonocytic Leukemia, Previously Treated Myelodysplastic Syndromes. PRIMARY OBJECTIVE: I. Compare improvement in event-free survival of patients with hematologic cancer or other diseases undergoing filgrastim (G-CSF)-stimulated bone marrow transplantation (BMT) vs conventional BMT. SECONDARY OBJECTIVES: I. Compare the incidence and time to engraftment in patients treated with these regimens. II. Compare rates of acute and chronic graft-vs-host disease (GVHD) in patients treated with these regimens. III. Correlate incidence of acute and chronic GVHD with absolute T-cell numbers, Th1 vs Th2 profile of T cells, dendritic cell populations, and T-regulatory cell content. IV. Assess the impact of G-CSF-stimulated BMT as a stem cell source on hospital stay and treatment-related mortality at day 100 in patients treated with this regimen. OUTLINE: This is a randomized, multicenter study. Patients are stratified according to risk (high vs intermediate vs standard). CONDITIONING REGIMEN: Co-enrolled on COG-ASCT0431 or COG-AAML0531; Patients receive a conditioning regimen as defined on that treatment study. ACUTE LYMPHOBLASTIC LEUKEMIA (ALL): Patients undergo total-body irradiation (TBI) twice daily on days -8 to -6. Patients receive thiotepa IV on days -5 and -4 and high-dose cyclophosphamide IV over 1 hour on days -3 and -2. Some patients with CNS leukemia or very high-risk ALL in first complete remission receive cranial radiotherapy. ACUTE MYELOID LEUKEMIA, JUVENILE MYELOMONOCYTIC, CHRONIC MYELOGENOUS LEUKEMIA, OR MYELODYSPLASTIC SYNDROMES: (myeloid malignancies) Patients receive busulfan IV over 2 hours every 6 hours on days -9 to -6 and high-dose cyclophosphamide IV over 1 hour on days -5 to -2. GRAFT-VS-HOST DISEASE (GVHD) PROPHYLAXIS: Co-enrolled on COG-ASCT0431 or COG-AAML0531: Patients undergo GVHD prophylaxis as defined on that treatment study. ALL: Patients receive tacrolimus IV or orally
