title: Adoptable strategic approaches to improve outcomes of allogeneic peripheral blood stem cell transplantations from unrelated donors.
abstract: While previous studies have shown comparable clinical results for related and unrelated bone marrow transplantation (BMT), the transplantation outcomes for related and unrelated peripheral blood stem cell transplantation (PBSCT) may not follow the same pattern due to a higher incidence of graft-versus-host disease (GVHD)-related morbidity and mortality in the case of long-term survival after unrelated PBSCT. Thus, given the higher possibility of an impaired quality of life due to severe GVHD in long-term survivors who receive unrelated PBSCT, the selection of the stem cell source needs to be decided very carefully. In addition, strategic approaches, such as the extended use of immunosuppressant as a GVHD prophylaxis, the use of antithymocyte globulins (ATGs), choosing a younger donor, and optimizing the CD34+ cell dose, need to be adopted to improve the transplantation outcomes by minimizing GVHD-related morbidity and mortality in an unrelated PBSCT setting. This review article provides a comparison of BMT and PBSCT, and related and unrelated PBSCT, plus introduces several adoptable strategies to improve the outcomes of unrelated PBSCT.
