OBJECTIVES: I. Determine the feasibility of allogeneic engraftment after unrelated matched allogeneic peripheral blood stem cell transplantation preceded by a nonmyeloablative, fludarabine based conditioning regimen in patients with advanced hematologic malignancies. II. Determine the toxicities of this regimen, especially graft versus host disease, in these patients.
OUTLINE: Patients receive fludarabine IV over 30-60 minutes on days -7 to -4, cyclophosphamide IV over 30 minutes on days -7 to -5, and cytarabine IV over 2 hours on days -4 and -3. Allogeneic peripheral blood stem cells are infused on day 0. Filgrastim (G-CSF) is administered IV over 1 hour or subcutaneously beginning on day 1 and continuing until blood counts recover. Patients are followed weekly until day 60 and then monthly for 10 months.
PROJECTED ACCRUAL: A total of 6 patients will be accrued for this study.
