Stay up-to-date on the advancing field of HCT with short summaries and links to the most relevant published research.

Gooptu M, et al., Blood—An observational study from the CIBMTR Graft Sources Working Committee found that 8/8 matched unrelated donor hematopoietic cell transplantation (HCT) with PTCy based graft versus host disease (GVHD) prophylaxis resulted in superior overall survival and disease-free survival compared to haploidentical HCT with PTCy in the reduced intensity conditioning (RIC) setting for treatment of acute leukemia and myelodysplastic syndromes. It is the first known study that offers a direct comparison between the two donor sources using PTCy.

Use of MMUDs can expand HCT access for ethnically diverse populations.

John M. Pagel, MD, PhD, Megan Othus, PhD, et al – Barriers to human leukocyte antigen (HLA) typing and cytogenetic testing can significantly impact the overall survival of patients newly diagnosed with acute myeloid leukemia (AML).  In this landmark study, a concerted effort to address those issues and streamline the initiation of donor identification and referral for hematopoietic cell transplant (HCT) consultation in early disease state led to a higher CR1 transplantation rate and improved 2-year overall survival.

Hsu J, et. al., Blood—Researchers presented data at the 62nd ASH Annual Meeting and Exposition on the impact of using fresh versus cryopreserved allogeneic bone marrow (BM) and peripheral blood stem cells (PBSC) grafts on patient allogeneic hematopoietic cell transplant (alloHCT) outcomes.

Auletta J, et al., Transplantation and Cellular Therapy—A manuscript published in Transplantation and Cellular Therapy offered the first report on the impact of the COVID-19 pandemic on the ability of the National Marrow Donor Program® (NMDP)/Be The Match® and the Network to safely deliver unrelated donor products early in the pandemic. The authors found that the NMDP/Be The Match and Network partners continued to effectively deliver domestic and unrelated donor products to allogeneic transplant patients in similar or shorter timeframes than before COVID-19, despite the many unexpected challenges brought about by the pandemic.

Nakamura, R et al., ASH oral abstract presentation, December 2020—Patients ages 65 and older with MDS who received an allogeneic hematopoietic cell transplantation (alloHCT) saw a similar benefit to overall survival (OS) as younger patients (50-64) when compared to other treatments.

Maakaron J, et al., ASH abstract poster presentation, December 2020—The CIBMTR® (Center for International Blood and Marrow Transplant Research®) presented their study results suggesting that efforts should focus on minimizing residual disease and better donor selection as age alone is not a barrier to successful hematopoietic cell transplantation (HCT) for acute myeloid leukemia (AML) in CR1 and should not exclude patients from HCT.

Dehn J, et al., Blood – A panel of immunogeneticists and other experts in the field of hematopoietic cell transplantation (HCT) has published updated evidence-based guidelines for the optimal selection of unrelated donors and cord blood units used for transplants.

The updated guidelines make recommendations for both HLA and non-HLA factors to consider in graft selection, including donor availability, donor age, patient sensitivity to HLA antigens, natural killer (NK) cell alloreactivity, and minimum total nucleated cell doses and CD34+ cell doses for cord blood units.


Shimoni A, et al., Biol Blood Marrow Transplant – In an analysis of 1134 patients age 50 or older with acute myeloid leukemia (AML), two-year hematopoietic cell transplant (HCT) survivors experienced comparable 10-year leukemia-free survival (LFS) and overall survival (OS) with matched sibling or unre-lated donors.


Cappelli B, et al. Haematologica – The youngest of three age-based patient cohorts (age 0-5 years) in a study of 736 patients with sickle cell disease (SCD) undergoing HLA-identical sibling hematopoietic cell transplantation (HCT) experienced 4-year event-free survival of 93%, results the researchers characterized as “excellent.” 

Bolaños-Meade J, et al., The Lancet Haematology – In a prospective, phase II trial, researchers found that tacrolimus, mycophenolate mofetil, with post-hematopoietic cell transplant (HCT) cyclophosphamide (TMMCy) produced the best GVHD-free, relapse-free survival (GRFS) for patients who received an allogeneic HCT when compared to the current standard of care.

Zeiser R, et al. Blood – The latest research in cellular therapies, antibody-based treatments, and tyrosine kinase inhibitor (TKI)-based approaches to enhance GVL effects are outlined in articles published in a special edition of Blood.
