Donor Stem Cell Transplant Followed By Donor White Blood Cell Infusions in Treating Young Patients With Hematologic Cancer

• Status: Terminated
• Trial end date: 2007-11-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Giving chemotherapy before a donor peripheral blood stem cell transplant helps stop both the growth of cancer cells and the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient, they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving chemotherapy, such as fludarabine and melphalan, and antithymocyte globulin before transplant and cyclosporine and methotrexate after transplant may stop this from happening.

PURPOSE: This clinical trial is studying how well donor stem cell transplant, using low-dose chemotherapy and antithymocyte globulin, followed by donor white blood cell infusions work in treating young patients with hematologic cancer.
