Official Title: Low-Dose TBI and Fludarabine Followed by Nonmyeloablative Unrelated Donor Peripheral Blood Stem Cell Transplantation Using Enhanced Postgrafting Immunosuppression for Patients With Hematologic Maligna
Brief Summary: This phase I/II trial studies whether a new kind of blood stem cell (bone marrow) transplant, that may be less toxic, is able to treat underlying blood cancer. Stem cells are "seed cells" necessary to make blood cells. Researchers want to see if using less radiation and less chemotherapy with new immune suppressing drugs will enable a stem cell transplant to work. Researchers are hoping to see a mixture of recipient and donor stem cells after transplant. This mixture of donor and recipient stem cells is called "mixed-chimerism". Researchers hope to see these donor cells eliminate tumor cells. This is called a "graft-versus-leukemia" response.
