Key PointsQuestion
Should bone marrow or peripheral blood be used for hematopoietic cell transplantation from unrelated donors?
Findings
In this follow-up of a randomized clinical trial, recipients of unrelated donor bone marrow had the same 5-year survival with better psychological well-being, less burdensome chronic graft-vs-host disease symptoms, and a higher likelihood of returning to work than recipients of peripheral blood.
Meaning
Bone marrow should be used instead of peripheral blood for unrelated donor transplantation when calcineurin inhibitor/methotrexate-based graft-vs-host disease prophylaxis is used.
Importance
Bone marrow or peripheral blood from unrelated donors may be used for hematopoietic cell transplantation. Information about the relative success of transplantation with these 2 graft sources would help physicians and patients choose between them.
Objective
To compare patient-reported outcomes between patients randomized to receive 1 of 2 graft types for unrelated donor transplantation.
Design, Setting, and Participants
This follow-up of a randomized clinical trial included English- or Spanish-speaking patients 16 years or older participating in a multicenter randomized clinical trial of unrelated donor bone marrow (BM) vs peripheral blood (PB) (N = 551) in hematopoietic cell transplantation for hematologic neoplasms. Patient-reported outcomes were collected from patients at enrollment and 0.5, 1, 2, and 5 years after transplantation.
Interventions
Unrelated donor BM or PB hematopoietic cell transplantation.
Main Outcomes and Measures
Functional Assessment of Cancer Therapy–Bone Marrow Transplant, Mental Health Inventory, occupational functioning, Lee Chronic Graft-vs-Host Disease Symptom Scale.
Results
At 5 years after transplantation, 102 BM and 93 PB participants were alive and eligible for assessment (age ≥40 years or older: 104 [53.5%] male: 101 [51.8%]). The mean (SE) Mental Health Inventory Psychological Well-Being scores (78.9 [1.7] vs 72.2 [1.9]; P = .01; higher better) and Lee chronic graft-vs-host disease symptom scores (13.1 [1.5] vs 19.3 [1.6]; P = .004; lower better) were significantly better for BM recipients, adjusting for baseline scores and missing data. Recipients of BM were also more likely to be working full or part-time than recipients of PB (odds ratio, 1.5; 95% CI, 1.2-2.0; P = .002), adjusting for work status before transplantation. With a median follow-up of 73 months (range, 30-121 months) for survivors, no differences in survival (40% vs 39%; P = .84), relapse (32% vs 29%; P = .47), or treatment-related mortality (29% vs 32%; P = .44) between BM and PB were observed.
Conclusions and Relevance
Recipients of unrelated donor BM had better psychological well-being, less burdensome chronic GVHD symptoms, and were more likely to return to work than recipients of PB at 5 years after transplantation. Bone marrow should be the standard of care for these types of transplant procedures.
