Active infection at the time of CD34+ selected stem cell boost is associated with treatment failure and poor overall survival.

Abstract

The use of CD34+ selected stem cell boost (SCB) after allogeneic hematopoietic cell transplant (allo-HCT) has been increasing. Predictors of treatment failure after SCB, both in the context of poor graft function (PGF) or other settings, are not well characterized. We report among the largest single-center retrospective experiences of the use of SCB and evaluate potential predictors of response and outcomes. A total of 58 patients who underwent HCT between 2015 and 2022 and who received SCB, were identified. The indication for SCB was predominantly PGF, defined as the presence of ≥2 cytopenias for at least 2 consecutive weeks beyond day +14 after allo-HCT in the presence of ≤30% bone marrow cellularity and ≥90% donor myeloid chimerism in the absence of morphologic disease.
