This helps more people of color get BMT. That’s because people of color are less likely to have a fully matched donor. Now, anyone without a fully matched donor can use a mismatched donor.
There are 3 types of mismatched donors:
- Half-matched (haploidentical), usually a parent or child
- Mismatched, unrelated
- Umbilical cord blood
In the past, people who got mismatched donors did not live as long, often because they got a serious effect called graft-versus-host disease (GVHD).
Recently, doctors found better medicines to prevent GVHD. These medicines are cyclophosphamide and abatacept.
In the last 10 years, compared to the past, more people got half-matched BMT with cyclophosphamide medicine.
Although more White patients got BMT than patients of other races, a higher percentage of people of color got halfmatched or mismatched BMT. That includes patients who were Black or African American, Hispanic, Asian and other races.
Finally, people in all racial and ethnic groups are living longer after BMT now than in the past.
