- What is a "Bone Marrow Transplant"?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: I know that organs may be transplanted but now I've heard the term
- "bone marrow transplant." What is it? What is it used for?
-
- ------------------------------------------------------------------------------
-
- ANSWER: A bone marrow transplant replaces a patient's abnormal or diseased
- marrow with healthy marrow from a donor. The new marrow contains a stem-cell
- population that can differentiate into blood cells that will replace the cells
- affected by disease. Such treatment can be helpful for some patients
- suffering the effects of leukemia, lymphoma (cancer of the lymph system),
- certain types of anemia and/or inherited blood disorders (one such is called
- thalassemia) and those seriously weakened by radiation and/or chemotherapy.
- There are three types of bone marrow transplants: autologous--from the
- patient's own marrow, removed prior to treatment with chemo or radiation
- therapy. The removed marrow also may be treated before being retransplanted
- in the patient: syngeneic--from an identical twin and is genetically
- identical to the patient: and the most common type, the allogeneic--from a
- brother, sister or parent. Until now the most successful grafts have been
- from those identical twins.
- Whoever the donor may be, he/she must have nearly identical genetic
- characteristics with the patient or the transplant probably will not survive,
- although with immunosuppressive preparation, success rates are continually
- improving.
