Abstract

The immune reactivity of allogeneic lymphocytes plays a major role in control of leukemia after bone marrow transplantation. We studies the efficacy of donor leukocyte transfusion (DLT) on acute and chronic leukemia in relapse after bone marrow transplantation in Japan. Sixty nine patients with chronic myelocytic leukemia (N = 17), acute lymphoblastic leukemia (N = 25), acute myelocytic leukemia (N = 26), myelodysplastic syndrome (N = 5), non-Hodgkin lymphoma (N = 2) and rhabdomyosarcoma (N = 1) were treated with transfusions of donor lymphocytes. Therapeutic effects were induced by donor leukocyte transfusion in 20 patients (29%) including 3 patients out of 4 (75%) with CML in cytogenetic and chronic phase relapse, 4 out of 5 (80%) patients with myelodysplastic syndrome, 3 out of 13 (23%) patients with CML in transformed phase, 5 out of 25 (20%) patients with acute myelocytic leukemia, and 4 out of 20 (20%) patients with acute lymphoblasic leukemia. Twenty two patients (30%) developed acute GVHD (> or = 2) and 6 out of 73 (8.2%) patients developed fatal GVHD after donor leukocyte transfusion. Patients relapsed within 6 months after marrow transplantation had a probability of having severe acute GVHD (> or = 2) after DLT. Fourt...Continue Reading

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

B-cell leukemia includes various types of lymphoid leukemia that affect B cells. Here is the latest research on B-cell leukemia.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
