Cyclophosphamide Plus Transplantation of Partially HLA-mismatched, CD8+ T Cell-depleted Peripheral Blood Cells for Patients With Myelodysplastic Syndrome , Refractory Acute Myeloid Leukemia, Refractory Lymphoma or Myeloproliferative Disorders
RATIONALE: Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of abnormal blood cells, either by killing the cells or by stopping them from dividing. Giving cyclophosphamide together with donor lymphocytes that have been treated in the laboratory may be an effective treatment for myelodysplastic syndromes or myeloproliferative disorders.
PURPOSE: This clinical trial is studying the best dose of donor lymphocytes when given together with cyclophosphamide in treating patients with myelodysplastic syndromes or myeloproliferative disorders.
Biological: donor lymphocytes

|Official Title:||Cyclophosphamide Plus Transplantation of Partially HLA-Mismatched (Haploidentical), CD8+ T Cell-Depleted Peripheral Blood Cells (PBCs) for Patients With Myelodysplastic (MDS) or Myeloproliferative Disorders (MPD)|
- Maximum tolerated dose of CD8-positive T-cell-depleted haploidentical donor lymphocytes [ Designated as safety issue: Yes ]
|Study Start Date:||May 2006|
|Study Completion Date:||May 2011|
|Primary Completion Date:||May 2011 (Final data collection date for primary outcome measure)|
- Determine the maximum tolerated dose of allogeneic CD8-positive T-cell-depleted, haploidentical donor lymphocytes when given after cyclophosphamide in patients with myelodysplastic syndromes or myeloproliferative disorders.
OUTLINE: Patients receive cyclophosphamide on days 1 and 2. Patients then undergo infusion of allogeneic T-cell depleted donor lymphocytes on day 3.
Cohorts of patients receive escalating doses of CD8-positive T-cell-depleted haploidentical donor lymphocytes until the maximum tolerated dose is determined.
PROJECTED ACCRUAL: A total of 44 patients will be accrued for this study.
