Filter by:RATIONALE: Giving chemotherapy, such as busulfan, fludarabine, and melphalan, before a donor umbilical cord blood stem cell transplant helps stop the growth of abnormal or cancer cells and prepares the patient's bone marrow for the 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 cyclosporine and mycophenolate mofetil may stop this from happening. PURPOSE: This phase II trial is studying how well combination chemotherapy followed by a donor umbilical cord blood transplant works in treating infants with high-risk acute leukemia or myelodysplastic syndromes.
The purpose of this study is to evaluate the incidence of neutrophil engraftment after transplantation of one or two cord blood units meeting a predetermined total minimum cell dose of 2.0 x 10 to the seventh total nucleated cell (TNC)/kg.
Primary Objective: A. To determine whether stable allogeneic hematopoietic engraftment can be safely established in patients receiving a non-myeloablative allogeneic SCT from a matched sibling donor, with fludarabine and low-dose TBI, with pre- and post-transplant immunosuppression with tacrolimus and MMF. B. To evaluate the incidence of grade II-IV GVHD associated with this treatment.
RATIONALE: Giving low doses of chemotherapy, such as fludarabine and cyclophosphamide, and radiation therapy before a donor umbilical cord blood 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 system 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 after transplant may stop this from happening. PURPOSE: This clinical trial is studying how well giving fludarabine and cyclophosphamide together with total-body irradiation followed by cyclosporine and mycophenolate mofetil works in treating patients who are undergoing a donor umbilical cord blood transplant for hematologic cancer.
Primary Objectives: This a pilot project to determine the feasibility of the preemptive CD8+ depleted T-cell donor lymphocyte infusion (DLI) in: - Reducing the incidence of graft versus host disease (GVHD) based on standard classification of acute and chronic GVHD - Improving hte disease remission rate in comparison with our previous study results. Secondary Objectives: - To investigate the impact of CD8+ depleted T-cell DLI in hematopoietic chimerism, and immunologic recovery of transplant patients.
In this trial, HLA-A2+ patients with active AML are vaccinated with a peptide from the leukemia-associated antigen WT1 together with immunological adjuvants keyhole limpet hemocyanin (KLH) as T-helper protein and granulocyte macrophage colony stimulating factor (GM-CSF) 4 times bi-weekly, then monthly.
RATIONALE: Umbilical cord blood transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy. PURPOSE: This phase II trial is studying how well umbilical cord blood works as a source of stem cells in treating patients with types of cancer as well as other diseases.
RATIONALE: Light-emitting diode (LED) therapy may be able to prevent mucositis of the mouth. PURPOSE: Randomized phase II trial to determine the effectiveness of LED therapy in preventing mucositis of the mouth in children who are receiving chemotherapy with or without radiation therapy before donor bone marrow transplantation.
