Hypothesis
Can donor center-initiated HLA typing improve the chances of finding HLA-matched unrelated donors for patients in need of stem cell transplants?
Conclusion
Donor center-initiated HLA typing can improve the chances of patients finding HLA-matched unrelated donors.
Supporting Evidence
- 8,861 donors were contacted for additional HLA typing.
- 12 donors have donated stem cells so far, with 8 donating for their respective target patients.
- The median time from typing request to donation was 85.5 days.
Takeaway
This study shows that checking more details about stem cell donors can help patients find better matches for their transplants.
Methodology
The study involved contacting 8,861 donors for additional HLA typing during 1,089 donor searches.
Limitations
The study was limited to 3-locus low-resolution matching and did not consider potential donors outside the DKMS file.
