The purpose of this study is to show that myeloablative hematopoietic progenitor cell transplantation (HPCT) continues to offer acceptable disease-free survival for select patients requiring HPCT.
Sat, 03/01/2008 to Wed, 01/01/2020
Bone Marrow Disease(s):
myelodysplastic syndromes (MDS)
Drug: Myeloablative Chemotherapy Regimen for Lymphoid Malignancies or Cord Blood Unit Recipients Total Body Irradiation (TBI) 1200 cGy will be given on days -8,-7,-6 and -5 in eight sessions, delivering 150cGy in each session. Etoposide 1000 mg/m2 as a 24 hour continuous infusion started on day -4. Cyclophosphamide 60 mg/kg/day IV given over 1 hour daily on days -3, -2. Drug: Myeloablative Chemotherapy Regimen for Non-Cord Blood Unit Recipients with Myeloid Malignancies Busulfan administration: For children >/= 4 years of age, Busulfan 0.8 mg/kg/dose will be given every 6 hours over days -8,-7, -6, and -5 for a total of 16 doses. For children < 4 years of age, Busulfan 1 mg/kg/dose will be given every 6 hours over days -8, -7, -6, -5 for a total of 16 doses. Pharmacokinetic analysis will guide dose modifications targeted to receive an average AUC of 800-1200 microMols*min for the 16 doses. Lorazepam (0.05 mg/kg) IV will be administered one half hour before the initial dose of Busulfan is given and every 6 hours through day -4. Etoposide 1000 mg/m2 as a 24 hour continuous infusion started on day -4. Cyclophosphamide 60 mg/kg/day IV given over 1 hour daily on days -3 and -2. Other: Hematopoietic Progenitor Cell Transplantation (HPCT) Hematopoietic progenitor cells (HPCs) will be infused on day 0. Source of cells may be bone marrow, peripheral blood cells, or cord blood units, from matched related or unrelated donors. Radiation: CNS radiation treatment for ALL with prior CNS disease patients Patients with prior CNS disease over the age of 1 year will be treated with 600 cGy of cranial irradiation in addition to 1200 cGy of TBI. Patients diagnosed with ALL with CNS disease (at the time of diagnosis or relapse) < 1 year of age will receive CNS treatment as Intrathecal Methotrexate as follows: Infants ≤ 1 year of age at the time of Intrathecal Therapy will receive a dosing of 7.5 mg once a month for 6 months after transplant beginning at day +30 with an adequate white count Children 1-2 years of age at the time of Intrathecal Therapy will receive 8 mg once a month for 6 months after transplant beginning at day +30 with an adequate white count
