Brief Summary: RATIONALE Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells
PURPOSE This phase II trial is studying how well giving busulfan cyclophosphamide and filgrastim together with peripheral stem cell transplantation from a sibling donor works in treating patients with hematologic cancer
Detailed Description: 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 busulfancyclophosphamide 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
