The number of allogeneic hematopoietic stem cell (HSC) transplants performed globally each year continues to increase. Advances in HLA typing, better supportive care, and administration of reduced-intensity conditioning regimens allow treatment of older patients with older sibling donors. Pretransplant donor assessment and testing are very important processes affecting the quality and safety of donation. For unrelated HSC donors detailed recommendations for health assessment have been published, allowing donation only if they are unrestrictedly healthy. Eligibility criteria for related donors are less strict and vary significantly between centers. In situations where a family donor does not meet the suitability criteria for unrelated donors, involved physicians often struggle with the decision whether the matched relative is suitable for donation or not. On behalf of the Worldwide Network for Blood and Marrow Transplantation Standing Committee on Donor Issues, we intended to develop a consensus document with recommendations for donor workup and final clearance of family donors who would not be able to serve as unrelated donors because of their age or pre-existing diseases. This article covers different topics intending to support decision-making, with the goal of minimizing medical risk to the donor and protection of the recipient from transmissible diseases.

This study shows than women and donors who are lighter than their recipient have a decreased likelihood of meeting the transplant physician's requested dose. New strategies to improve mobilization in such donors are needed. These findings may also impact future donor recruitment strategies.

The physical reactions to hematopoietic stem cell donation have been extensively studied, but less is known about factors that predict poorer donation experiences. The aim of this prospective study was to examine demographic and health-related quality of life (HRQOL) factors that might be associated with recovery and side effects. We also described the changes in HRQOL during the donation process. In total, 275 peripheral blood stem cell (PBSC) and 37 bone marrow (BM) consecutive donors completed the SF-36 questionnaire predonation and 4 weeks, and 3 months postdonation. Predonation HRQOL markers were the strongest predictors of time to recovery. Poorer predonation physical health was associated with longer recovery (P = .017) and certain side effects in PBSC donors. Poorer predonation mental health was associated with longer recovery in BM donors (P = .03) and pain after PBSC donation (P = .003). Physical HRQOL scores declined significantly from predonation to 4 weeks postdonation. This was shown both for PBSC and BM donors (P < .001 and P = .009, respectively), but the decline was much greater for BM donors. There was a return to predonation HRQOL values 3 months after donation in both groups with values well above the mean of the general population (P < .001).
