In this article from Blood Advances highlighted by helpful visual abstracts, two key points are discussed. First, patient-specific next-generation sequencing (NGS)-based measurable residual disease (MRD) monitoring using non-DTA mutations after allogeneic hematopoietic cell transplantation (alloHCT) is independently prognostic for relapse and survival. Second, the kinetics rather than a single time point should be further evaluated when DTA mutations are used for MRD monitoring after alloHCT.
