(HealthDay News) — Most suitable candidates in the United States who need a bone marrow transplant can find an acceptable match through the National Marrow Donor Program, according to a new study.

The findings, said to represent the first attempt to accurately determine the successful-match rate of the bone marrow registry, are published in the July 24 issue of the New England Journal of Medicine.

Depending on a patient's race or ethnic background, the researchers found that 66–97% of patients will have a suitably matched and available live donor on the registry. Even hard-to-match ethnic groups can find a suitable donation thanks to banked stem cells drawn from umbilical cord-blood donations, senior author Martin Maiers, director of bioinformatics research at the National Marrow Donor Program, told HealthDay.
