PRIMARY OBJECTIVES: I. To determine the safety and potential toxicities associated with infusing donor CD8+ cytotoxic T lymphocyte (CTL) clones specific for Wilms' tumor (WT1) in patients who have relapsed or at a high risk of relapse post transplant for myelodysplastic syndromes (MDS), chronic myelogenous leukemia (CML), acute myeloid leukemia (AML), or acute lymphoblastic leukemia (ALL). SECONDARY OBJECTIVES: I. To determine the in vivo persistence of transferred T cells and assess migration to the bone marrow, a predominant site of leukemic relapse. II. To determine if adoptively transferred WT1-specific T cells mediate antileukemic activity. OUTLINE: Donors undergo leukapheresis for stem cell harvest to generate CD8-positive WT1 gene-specific CTL clones at the time of allogeneic stem cell transplantation. After post-transplantation hematopoietic recovery, patients receive treatment for either highest-risk disease (prophylactically) or relapsed disease. Highest-risk disease group: Patients receive CD8-positive WT1 gene-specific CTL clones intravenously (IV) over 1-2 hours on days 0, 14, and 28. Beginning 2-4 hours after CTL infusion, patients receive interleukin-2 subcutaneously (SC) twice daily on days 28-42 in the absence of unacceptable toxicity. Relapsed-disease group: Some patients with evidence of leukemic relapse may receive standard salvage chemotherapy prior to donor CTL infusions and then receive CD8-positive WT1 gene-specific CTL clones and interleukin-2 as in the highest-risk group. Patients in both groups who have progressive disease after complete or partial response to therapy may be eligible for retreatment with CD8-positive WT1 gene-specific CTL clones. After completion of study treatment, patients are followed every 3 months for 2 years.
