简要总结
RATIONALE: Giving chemotherapy before a donor umbilical cord blood 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 busulfan, and antithymocyte globulin before transplant and tacrolimus and mycophenolate mofetil after transplant may stop this from happening.
PURPOSE: This clinical trial is studying how well giving low-dose fludarabine and busulfan together with anti-thymocyte globulin, followed by donor umbilical cord blood transplant works in treating patients with advanced hematologic cancer.
详细描述
OBJECTIVES:
Primary
- Assess the feasibility of performing umbilical cord blood transplants in older patients or younger infirm patients with advanced hematologic malignancies using a reduced-intensity preparative regimen, as determined by > 80% engraftment rate at day 180 and a < 50% transplant-related mortality rate at day 100.
Secondary
- Describe the time to neutrophil and platelet recovery in patients treated with this regimen.
- Determine disease-specific, event-free, and overall survival rate at days 180 and 360.
- Determine the incidence, severity, and timing of acute and chronic graft-versus-host disease in patients treated with this regimen.
- Evaluate T-cell, B-cell, and natural killer cell recovery in patients treated with this regimen.
- Assess lineage-specific chimerism after transplantation and describe the contribution of each individual cord blood unit to post-transplantation hematopoiesis.
