The NMDP Transplant Center Directory shows statistics (data) for U.S transplant centers that are provided by the Center for International Blood and Marrow Transplant Research (CIBMTR®). Ask your doctor what this data might mean for you.

Use the Getting Started Worksheet to help you read individual transplant center listings.

Center’s Performance

  • The center’s overall one-year survival can be:
    • Above the expected range
    • Within the expected range
    • Below the expected range

Expected range for one-year survival

The graphs in the directory show the center’s actual 1-year survival and the expected range.

  • Actual 1-year survival: Shows how many people were alive 1 year after transplant at this center. It can be below, similar to, or above the expected range. This cannot tell you how you will do after transplant. Talk to your doctor to understand the likely course of your disease.
  • Expected range: Shows what doctors and researchers expect the 1-year survival to be at this center. It’s calculated by comparing survival at all centers that treated patients with similar diseases. This is based on things that can affect survival, such as HLA matching, the patient’s age, disease, and overall health before transplant.

All centers that have 1-year survival ratings in the same category (below, similar to or above the expected range) have comparable survival. This is true even if the actual survival numbers are different. For example, a center with 1-year survival of 72% is not necessarily better than a center with 1-year survival of 62% if they’re both in the same category. This is because the centers may treat patients with different risk factors that affect survival.

These survival data do not predict any individual patient’s 1-year survival because everyone’s experience is unique.

Total transplants

Each listing shows the number of transplants each center has done. It also breaks down the numbers by different factors including:

  • The patient’s age (adult or pediatric)
  • The type of donor (related or unrelated allogeneic and autologous)
  • The type of cells (marrow, peripheral blood stem cells (PBSC) or umbilical cord blood)

Transplants by disease

The directory also shows the number of transplants for a specific disease. It shows how many patients with that disease had a transplant by the type of donor (related, unrelated or autologous) by age group. This can help you and your doctor find out how many patients similar to you were treated at a center. This list shows the diseases treated by transplant.
