A blood or marrow transplant begins with chemotherapy, with or without radiation, to destroy the diseased cells and marrow. The transplant replaces diseased blood-forming cells with healthy ones.

There are two types of blood and marrow transplants: allogeneic and autologous. An allogeneic transplant uses healthy blood-forming cells from a family member, unrelated donor, or umbilical cord blood unit. An autologous transplant uses the patient’s own blood-forming cells which are collected and stored.

Most transplants for ALL are allogeneic. Autologous transplant isn’t usually used for ALL because the risk of relapse (a return of the disease) is higher than with allogeneic transplant.

Understanding if transplant would help your ALL

Be The Match is here to assist you and your family as you plan for transplant. Our patient services coordinators can answer your questions and provide support and education to help you navigate your transplant journey.

Whether a transplant is right for you depends on how likely the leukemia is to return. This is based on certain features of the leukemia, called risk factors, and your general health. A transplant doctor will weigh the risk of the leukemia coming back against getting a transplant. A transplant may cure the leukemia, but may also cause other problems. The doctor also considers whether your specific risk factors are a sign that chemotherapy is not likely to lead to a cure or long-term remission.

One way a doctor determines how likely the leukemia is to return is through cytogenetic testing. This means looking at the chromosomes in the leukemia cells. Chromosomes are thread-like strands of DNA that carry genetic information about your body. Certain changes in the chromosomes predict a lower risk of the disease returning. Others predict a higher risk.

If your disease has a high chance of returning and you are a good candidate for a transplant, delaying a transplant may lower your likelihood of long-term remission or cure.

There are medical guidelines for when someone should be referred for a transplant consultation, whether or not you might need a transplant at that time. Talking to a transplant doctor is especially recommended if your disease has any of the following features:

For ALL in adults:

  • Your initial chemotherapy doesn’t lead to remission within 28 days of starting treatment
  • Molecular or cytogenetic testing of the ALL shows high-risk disease
  • You relapse one or more times after chemotherapy 

For ALL in children:

  • Your child is an infant at diagnosis
  • Your child has high-risk features such as a high white blood cell count at diagnosis
  • Molecular or cytogenetic testing of the ALL shows high-risk disease
  • Child’s initial chemotherapy doesn’t lead to remission within 28 days of starting treatment
  • Child relapses one or more times after chemotherapy
