Clinical Trial Summary

RATIONALE: Bone marrow transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy used to kill cancer cells.

PURPOSE: Randomized phase II/III trial to determine the effectiveness of bone marrow transplantation in treating patients who have leukemia.

Description:

OBJECTIVES: I. Compare unrelated donor bone marrow transplantation using T-cell-depleted marrow versus unmodified marrow in adults and children with leukemia. II. Evaluate 2-year leukemia-free survival, primary and secondary graft failure, graft-versus-host disease, infection, and relapse in these patients. III. Assess the quality of life associated with T-cell-depleted versus unmodified, unrelated donor transplantation.

OUTLINE: This is a randomized, multicenter study. Patients are stratified by center. Patients receive myeloablative therapy according to diagnosis: those with acute lymphocytic leukemia and lymphoblastic lymphoma are treated with total body irradiation (TBI), with a testicular and chest wall boost as appropriate, followed by cyclophosphamide (CTX); patients with undifferentiated or biphenotypic leukemia or with acute or chronic myelocytic leukemia are treated with CTX followed by TBI. Patients are then randomly assigned to receive non-T-cell-depleted, unrelated marrow versus T-cell-depleted, unrelated marrow. The modified marrow is depleted of T-lymphocytes by counterflow elutriation and positively selected for CD34 cells. Graft-versus-host disease (GVHD) prophylaxis with cyclosporine and methotrexate is given to the unmodified marrow group. Patients who receive modified marrow are given antithymocyte globulin (or methylprednisolone) for graft rejection prophylaxis before transplantation and cyclosporine and methylprednisolone for GVHD prophylaxis after transplantation.
