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.
- 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.
- 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.
Primary Purpose: Treatment

Tolerance induction is an important goal in the field of organ transplantation. We have sequentially modified our conditioning regimen for induction of donor-specific tolerance in recipients of major ...
Determine the ocular complications in school-age children and adolescents surviving at least one year following allogeneic bone marrow transplantation.
Allogeneic hematopoietic stem cell transplantation (HSCT) is widely performed in children and adolescents with hematologic diseases including very high-risk leukemia. With increasing success and survi...
Techniques for the removal of subpopulations of cells (usually residual tumor cells) from the bone marrow ex vivo before it is infused. The purging is achieved by a variety of agents including pharmacologic agents, biophysical agents (laser photoirradiation or radioisotopes) and immunologic agents. Bone marrow purging is used in both autologous and allogeneic BONE MARROW TRANSPLANTATION.
Agents that destroy bone marrow activity. They are used to prepare patients for BONE MARROW TRANSPLANTATION or STEM CELL TRANSPLANTATION.
The transference of BONE MARROW from one human or animal to another for a variety of purposes including HEMATOPOIETIC STEM CELL TRANSPLANTATION or MESENCHYMAL STEM CELL TRANSPLANTATION.
Transfer of HEMATOPOIETIC STEM CELLS from BONE MARROW or BLOOD between individuals within the same species (TRANSPLANTATION, HOMOLOGOUS) or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). Hematopoietic stem cell transplantation has been used as an alternative to BONE MARROW TRANSPLANTATION in the treatment of a variety of neoplasms.
Preparative treatment of transplant recipient with various conditioning regimens including radiation, immune sera, chemotherapy, and/or immunosuppressive agents, prior to transplantation. Transplantation conditioning is very common before bone marrow transplantation.
Osteoporosis is a disease in which the bones become extremely porous, are subject to fracture, and heal slowly, occurring especially in women following menopause and often leading to curvature of the spine from vertebral collapse. Follow and track&n...
Organ transplantation is the moving of an organ from one body to another or from a donor site to another location on the patient's own body, for the purpose of replacing the recipient's damaged or absent organ. The emerging field of regenerative ...
