Donor Peripheral Stem Cell Transplant, Fludarabine, and Busulfan in Treating Patients With Hematologic Cancers

• Status: Completed
• Trial end date: 2013-11-01
• Target enrollment: 0
• Participant gender: All

Summary

Giving chemotherapy drugs, such as fludarabine and busulfan, before a donor peripheral stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil before and after the transplant may stop this from happening.

PURPOSE: This phase II trial is studying the side effects of giving donor peripheral stem cell transplant together with fludarabine and busulfan and to see how well it works in treating patients with hematologic cancers.
