Official Title: A Multi-Center, Phase II Trial of Nonmyeloablative Conditioning (NST) and Transplantation of Partially HLA-Mismatched Bone Marrow From Related Donors for Patients With Hematologic Malignancies (BMT CT
Brief Summary: Bone marrow transplants are one treatment option for people with leukemia or lymphoma. Family members or unrelated donors with a similar type of bone marrow usually donate their bone marrow to the transplant patients. This study will evaluate the effectiveness of a new type of bone marrow transplant—one that uses lower doses of chemotherapy and bone marrow donated from family members with only partially matched bone marrow—in people with leukemia or lymphoma.
