Summary

RATIONALE: Giving chemotherapy and total marrow and lymphoid irradiation before allogeneic hematopoietic cell transplant helps stop the growth of leukemia cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may achieve brand new hematopoietic recovery. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells, resulting in graft versus-host disease. PURPOSE: This study is to evaluate the toxicity and efficacy of total marrow and lymphoid irradiation conditioning when given together with combination chemotherapy and allogeneic peripheral blood stem cell transplant in treating patients with high-risk acute leukemia.

Detailed description

Patient receives preparative therapy including cyclophosphamide and total body irradiation (TBI) of 10 Gy or total marrow and lymphoid irradiation (TMLI) of 12-20 Gy, and starts immunosuppressive therapy using cyclosporine or tacrolimus, methotrexate-based prophylaxes, followed by peripheral blood stem cell transplantation and granulocyte colony-stimulating factor administration.

Conditions

• Acute Leukemia

Interventions

Type	Name	Description
RADIATION	total body irradiation	Drug: Cyclophosphamide 60 mg/kg/day intravenous x 2 days pre-transplant, total dose 120 mg/kg Drug: Cyclosporine or tacrolimus Beginning on Day -1 pre-transplant maintaining a level of 150-250 ng/ml or 5-10 ng/ml respectively. Cyclosporine or tacrolimus dosing will be monitored and altered as clinically appropriate by physician, and discontinue at approximately day + 180 post-transplant. Drug: Methotrexate 15 mg/m2 intravenous on days 1, 10 mg/m2 intravenous on days 3, 6 and 11 after transplantation. Intervention: Total Body Irradiation Dose of 10 Gy TBI (fraction size of 5 Gy given once a day on days -2 and -1). Procedure: Peripheral blood stem cell transplantation product will be infused via intravenous drip on Day 0.

Intervention: Total Marrow and Lymphoid Irradiation Dose of 12-20 Gy TMLI (fraction size of 4 Gy given once a day). Procedure: Peripheral blood stem cell transplantation product will be infused via intravenous drip on Day 0.
