简要总结
RATIONALE: Bone marrow and peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy used to kill cancer cells.
PURPOSE: Phase II trial to study the effectiveness of T-cell depleted bone marrow and G-CSF stimulated peripheral stem cell transplantation in treating patients with leukemia, lymphoblastic lymphoma, myelodysplastic syndrome, or aplastic anemia.
详细描述
OBJECTIVES:
- Determine the potential of T-cell-depleted bone marrow and peripheral blood stem cells (PBSC) from HLA-haplotype, partially matched related donors to induce extended disease-free survival in patients with leukemia, lymphoblastic lymphoma, myelodysplastic syndrome, or severe aplastic anemia who would otherwise be ineligible for transplantation because of the lack of an HLA-identical related or unrelated donor.
- Determine the impact of filgrastim (G-CSF)-stimulated, CD34+, E-rosette and T-cell-depleted PBSC derived from an HLA-haplotype, partially matched donor on the incidence and quality of engraftment, kinetics, and quality of hematopoietic and immunologic reconstitution, and incidence and severity of graft-versus-host disease (GVHD) in these patients.
- Correlate the doses of PBSC and clonable T-cells with the incidence of engraftment, extent of chimerism, incidence and severity of acute and chronic GVHD, characteristics of hematopoietic and immunologic reconstitution, and overall and disease-free survival rates at 2-4 years after transplantation in these patients.
OUTLINE: Patients are stratified by number of HLA-incompatible alleles (1 vs 2 or 3).
- Harvest: Beginning 6-10 days before transplantation, allogeneic bone marrow is harvested and treated in vitro. Beginning 5-6 days before transplantation, filgrastim (G-CSF)-stimulated, allogeneic peripheral blood stem cells (PBSC) are harvested, selected for CD34+ cells, and treated in vitro. If feasible, autologous bone marrow is harvested in the event of allogeneic graft failure.
- Myeloablation: Patients undergo total body irradiation 3 times a day on days -9 to -6, thiotepa IV over 4 hours on days -5 and -4, and cyclophosphamide IV on days -3 and -2.
- Transplantation: CD34+, E-rosette and T-cell-depleted PBSC are infused over 15 minutes and then T-cell-depleted bone marrow is infused over 1-5 minutes on day 0. Patients receive G-CSF IV over 30 minutes beginning on day 1 and continuing until blood counts recover and then tapering. Patients receive anti-thymocyte globulin IV over 4-6 hours on days 8, 10, 12, and 14 and oral methylprednisolone on days 8-14 followed by tapered doses on days 15-17.
- CNS prophylaxis: Beginning at least 2 months after transplantation, patients with acute lymphocytic leukemia (ALL) and no history of CNS leukemia receive cytarabine intrathecally (IT) monthly for 6 months and patients with ALL and a history of CNS leukemia receive cytarabine IT monthly for 12 months.
Patients with graft failure are offered autologous bone marrow transplantation (BMT) or second allogeneic BMT.
