Yoshimi A, Baldomero H, Horowitz M, et al. Global Use of Peripheral Blood vs Bone Marrow as Source of Stem Cells for Allogeneic Transplantation in Patients With Bone Marrow Failure. JAMA. 2016;315(2):198–200. doi:10.1001/jama.2015.13706
Hematopoietic stem cell transplantation (HSCT) is a therapeutic option for many patients with bone marrow failure.1 Bone marrow was initially the only stem cell source available until the 1990s when peripheral blood stem cells (PBSCs) and cord blood began to be used.
Currently, PBSCs are the major stem cell source,2 owing to faster engraftment and ease of collection despite a higher rate of graft-vs-host disease and lower survival rates in patients with nonmalignant disorders.3
Therefore, bone marrow is currently recommended for HSCT in patients with bone marrow failure.4 The objectives of this study were to investigate the use of PBSCs and bone marrow as stem cell sources for HSCT in patients with bone marrow failure worldwide and to identify potential factors associated with the use of each stem cell source.
