Bone marrow transplantation for the treatment of leukemia

Bone marrow transplantation can be used in some patients. The bone marrow that generates leukemia in the patient is destroyed by high doses of drugs and radiation;
Proper bone marrow can be taken from another person (ie donor), or can be taken from the same patient before high dose treatment. If we use the bone bone itself, it must be treated outside the body to rid it of leukemia cells.
Patients treated with bone marrow transplantation usually need to stay in hospital for several weeks. The patient must be protected from infection until the implanted bone marrow begins to produce enough leukocytes to protect the body from infection.
Patients undergoing bone marrow transplantation are at increased risk of infection, bleeding, and other side effects of chemotherapy and radiotherapy.
An imbalance can occur between the bone marrow implanted and the patient's body tissue; this is known as "bait-to-host disease". This disease may be mild or very severe and can occur at any time after bone marrow transplantation.
