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.
- 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.
Patients are followed at 1, 3, 6, and 12 months and then annually for 3 years.
PROJECTED ACCRUAL: A total of 60 patients (30 patients per stratum) will be accrued for this study at a rate of 15 leukemia patients and 5 aplastic anemia patients per year.

A water-soluble ester of METHYLPREDNISOLONE used for cardiac, allergic, and hypoxic emergencies.
A very toxic alkylating antineoplastic agent also used as an insect sterilant. It causes skin, gastrointestinal, CNS, and bone marrow damage. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), thiotepa may reasonably be anticipated to be a carcinogen (Merck Index, 11th ed).
A PREDNISOLONE derivative with similar anti-inflammatory action.
Congener of CYTARABINE that is metabolized to cytarabine and thereby maintains a more constant antineoplastic action.
A pyrimidine nucleoside analog that is used mainly in the treatment of leukemia, especially acute non-lymphoblastic leukemia. Cytarabine is an antimetabolite antineoplastic agent that inhibits the synthesis of DNA. Its actions are specific for the S phase of the cell cycle. It also has antiviral and immunosuppressant properties. (From Martindale, The Extra Pharmacopoeia, 30th ed, p472)
