S9920 Busulfan Compared With Cyclophosphamide in Patients Undergoing Total-Body Irradiation Plus Peripheral Stem Cell Transplantation for Advanced Myelodysplastic Syndrome or Related Acute Myeloid Leukemia

• Status: Completed
• Trial end date: 2006-03-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy used to kill tumor cells. It is not yet known if total-body irradiation plus peripheral stem cell transplantation is more effective with busulfan or with cyclophosphamide for myelodysplastic syndrome or acute myeloid leukemia.

PURPOSE: Randomized phase III trial to compare the effectiveness of busulfan with that of cyclophosphamide in patients undergoing total-body irradiation plus peripheral stem cell transplantation for advanced myelodysplastic syndrome or related acute myeloid leukemia.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Southwest Oncology Group
• Collaborator: National Cancer Institute (NCI)
• Treatments: Busulfan; Cyclophosphamide; Cyclosporine; Cyclosporins; Methotrexate
