RATIONALE: A bone marrow transplant from a brother or sister may be able to replace blood-forming cells that were destroyed by chemotherapy or radiation therapy. Colony-stimulating factors, such as G-CSF, cause the body to make blood cells. Giving G-CSF to the donor may help the body make more stem cells that can be collected for bone marrow transplant and may cause fewer side effects in the patient after the transplant. PURPOSE: This phase I/II trial is studying the side effects of donor bone marrow transplant and to see how well it works in treating young patients with cancer or a non-cancerous disease.
OBJECTIVES: Primary * Determine the safety and feasibility of filgrastim (G-CSF)-mobilized bone marrow from an HLA-identical pediatric sibling donor as a stem cell source for pediatric patients undergoing allogeneic bone marrow transplantation for malignant or non-malignant disease. Secondary * Determine the time to neutrophil and platelet engraftment, number of red blood cell and platelet transfusions, number of febrile days, and number of hospitalization days in patients treated with this regimen. * Determine the number of nucleated cells and CD34-positive cells, absolute lymphocyte count, and lymphocyte subsets (CD3/CD4/CD8) in G-CSF-mobilized bone marrow from these donors. OUTLINE: This is a multicenter, pilot study. Donors receive filgrastim (G-CSF) subcutaneously once daily on days -4 to 0. Donors then undergo standard bone marrow harvest on day 0. Patients receive pre-transplantation conditioning and graft-versus-host disease prophylaxis according to the disease for which the patient is being treated and the treatment plan or clinical trial for which the patient is enrolled on. Patients undergo allogeneic bone marrow transplantation on day 0. After completion of bone marrow harvest, donors are followed at 7 and 30 days. After completion of study treatment, patients are followed for 100 days post-transplantation and then periodically thereafter. PROJECTED ACCRUAL: A total of 80 participants (40 donors and 40 patients) will be accrued for this study within 18 months.
