How far along in leukemia can a bone marrow transplant be helpful?

Balancing act: Certainly one wants to try standard therapy first in most cases because it has less complications. If this approach is unsuccessful or the patient is very high risk, transplant is considered. The decision to go forward is complicated by such things as the patient's performance status, their prior treatments and the amount of disease. These way into the final decision of when it can be helpful.

It depends: There is no one answer. It depends on the type of leukemia, patient's age etc.
