Haploidentical transplantation.

Area of Science:

• Hematology
• Transplant Immunology
• Oncology

Background:

• Allogeneic hematopoietic stem cell transplantation (HSCT) is a curative option for various hematologic malignancies and other diseases.
• A matched sibling donor (MSD) is the preferred donor source, but is only available for a minority of patients.
• Unrelated donor searches are often initiated when an MSD is unavailable, which can lead to significant delays.

Purpose of the Study:

• To highlight the importance of considering family members as potential donors when a matched sibling donor is not available.
• To advocate for increased efforts in improving and expanding haploidentical transplantation.
• To emphasize the advantages of utilizing haploidentical related donors for hematopoietic stem cell transplantation.

Main Methods:

• Review of current practices in donor selection for allogeneic HSCT.
• Analysis of the potential for identifying suitable donors within the patient's family.
• Discussion of the benefits and challenges associated with haploidentical donor transplantation.

Main Results:

• Family members can serve as a viable donor source when an unrelated donor search is prolonged or unsuccessful.
• Haploidentical related donors can provide access to transplantation for a vast majority of patients.
• The advantages of haploidentical transplantation offer compelling reasons for its optimization.

Conclusions:

• Haploidentical transplantation should be more actively pursued when a matched sibling donor is unavailable.
• Improving and expanding haploidentical transplantation strategies is essential for increasing patient access to this life-saving procedure.
• Family-based donor typing should be prioritized to avoid delays in initiating transplantation.
