Brief summary
RATIONALE: Giving high-dose chemotherapy before an autologous stem cell transplant stops the growth of cancer cells by stopping them from dividing or killing them. An autologous stem cell transplant may be able to replace the blood-forming cells that were destroyed by the chemotherapy. PURPOSE: This phase II trial is studying how well giving busulfan together with cyclophosphamide followed by an autologous stem cell transplant works in treating patients with multiple myeloma.
Detailed description
OBJECTIVES: Primary * To compare relapse-free survival and overall survival of patients with multiple myeloma treated with IV busulfan vs historical control patients treated with oral busulfan when administered with cyclophosphamide as a conditioning regimen prior to autologous hematopoietic stem cell transplantation. Secondary * To compare pulmonary toxicity rates of IV busulfan vs oral busulfan when administered with cyclophosphamide as a conditioning regimen prior to autologous hematopoietic stem cell transplantation. OUTLINE: Patients receive high-dose busulfan IV every 6 hours on days -8 to -4 and high-dose cyclophosphamide IV over 4 hours on days -3 and -2. Patients undergo autologous hematopoietic stem cell transplantation on day 0. After completion of study treatment, patients are followed up periodically.
Interventions
IV busulfan 0.8 mg/kg every 6 hours x 16 doses
IV cyclophosphamide 60 mg/kg over 4 hours x 2 days
infusion of autologous hematopoietic stem cells of at least 2.0 x 106 CD34+ cells/kg on day 0
