Zusammenfassung
AbstractChimerism analysis is important for monitoring engraftment and indicating the recurrence of malignant cells after allogeneic hematopoietic stem cell transplantation. Highly sensitive methods with a detection limit of recipient cells (equivalents) below 0,1%, e. g. quantitative PCR, droplet digital PCR and, most recently, Next-Generation Sequencing, can predict a relapse up to 120 days earlier when compared to less sensitive methods. This review highlights the importance of assessing the dynamics of chimerism in the low percentage range (below 1%) for the prediction of a relapse. Moreover, the authors pro…
