OBJECTIVES: * Determine the safety and feasibility of using allogeneic peripheral blood progenitor cell infusions obtained from normal histocompatible sibling donors for reconstituting bone marrow and immunologic function when given after high-dose busulfan/cyclophosphamide in patients with a hematologic malignancy. * Determine the efficacy of this treatment in these patients. * Determine the ability to mobilize hematopoietic progenitor cells from normal donors given filgrastim (G-CSF) by determining the hematopoietic progenitor cell content of allogeneic peripheral blood progenitor cell collections. * Determine the incidence of engraftment failures in these patients. * Determine the incidence of severe acute graft-versus-host disease in these patients. OUTLINE: Patients receive high-dose oral busulfan every 6 hours on days -8 to -5, cyclophosphamide IV twice a day on days -4 and -3, and cyclosporine IV over 6 hours on day -1 and then 10 hours on day 0 for 2 doses (allogeneic only). Allogeneic peripheral blood progenitor cells IV are administered on day 0. Filgrastim (G-CSF) is administered subcutaneously twice a day beginning 3 hours after completion of cell infusion and continuing until blood counts recover. Patients are followed every month for 2 months, every 3 months for 6 months, and then every 6 months until disease progression. PROJECTED ACCRUAL: A total of 40 patients will be accrued over a 15 month period.
