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).
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.

- Toxicity rate associated with infusing donor CD8+ CTL clones specific for WT1 in patients at high risk for post transplant relapse of CML, AML, or ALL [ Time Frame: Up to 4 weeks after the final dose of CTL ]Assessed by Common Terminology Criteria (CTC) version 3.0.
- Relapse of disease [ Time Frame: Up to 2 years ]Patients achieving complete remission with chemotherapy and T cell infusions will be followed to determine the duration of response. The proportion of responders will be estimated with associated confidence intervals. Duration of remission will be summarized using time-to-event methods, which will allow estimates to be made while some patients remain in remission.
