T-cell Depletion In Unrelated Donor Marrow Transplantation


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.

Inclusion Criteria


DISEASE CHARACTERISTICS: Acute myelocytic leukemia with or without history of
myelodysplastic syndrome Not in first complete remission (i.e., greater than 5% blasts in
marrow) with t(8;21), t(15;17), or 16q abnormality unless failure on first-line induction
therapy Acute lymphocytic leukemia (ALL) in one of the following categories: In second or
third complete remission (CR) High-risk ALL in first CR, with high risk defined as:
Hypodiploidy OR pseudodiploidy with t(9;22), t(4;11), or t(8;14) Failure to achieve CR
after 4 weeks of induction therapy Elevated WBC at presentation, i.e.: Greater than
100,000 in patients aged 6 to 12 months Greater than 200,000 in patients aged 1 to 20
years Greater than 20,000 in patients aged 21 to 44 years Chronic myelogenous leukemia not
in blast crisis (i.e., no greater than 30% promyelocytes plus blasts in bone marrow) Stage
IV lymphoblastic lymphoma Undifferentiated or biphenotypic leukemia Unrelated donor
available Patients aged 35 and younger: HLA-A, and -B serologic identity and HLA-DRB1
identity by high-resolution DNA typing OR Single HLA-A or -B serologic mismatch with DRB1
identity by high-resolution DNA typing OR HLA-A and -B serologic identity with single DRB1
mismatch by high- or low- resolution DNA typing Patients aged 36 to 44: HLA-A and -B

exclude: Relapse 12 months after discontinuing therapy in patients aged 1 to 10 years who
are in second remission Active central nervous system or leukemic skin involvement
