What is intensity conditioning?
Reduced intensity conditioning refers to a conditioning regimen that uses less chemotherapy and radiation than the standard regimen, which destroys the patient’s bone marrow cells, (a result known as myeloablation).
What is mud transplant?
If you don’t have a good match in your family, a donor might be found in the general public through a national registry. This is sometimes called a MUD (matched unrelated donor) transplant. Transplants with a MUD are usually riskier than those with a relative who is a good match.
What is myeloablative conditioning?

How long can you live after a bone marrow transplant?
Some 62% of BMT patients survived at least 365 days, and of those surviving 365 days, 89% survived at least another 365 days. Of the patients who survived 6 years post-BMT, 98.5% survived at least another year.
What are the different types of bone marrow transplants?

- Autologous bone marrow transplant — The term auto means self.
- Allogeneic bone marrow transplant — The term allo means other.
- Umbilical cord blood transplant — This is a type of allogeneic transplant.
