T-Cell Infusion and Donor Stem Cell Transplant in Treating Patients with High-Risk Hematologic Cancer

Trial Status: administratively complete

This phase I/II trial studies the side effects and best way to give T-cell infusion and donor stem cell transplant and to see how well it works in treating patients with high-risk hematologic cancer. Giving chemotherapy and total-body irradiation (TBI) before a donor stem cell transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When certain stem cells from a related donor, that do not exactly match the patient's blood, 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. Removing the T cells from the donor cells before transplant may stop this from happening. Giving an infusion of the donor's T cells (donor lymphocyte infusion) may help the patient's immune system see any remaining cancer cells as not belonging in the patient's body and destroy them (called graft-versus-tumor effect).
