Abstract: This paper describes the successful mobilization of peripheral blood stem cells for autologous transplantation in three children with malignant diseases by using plerixafor (Mozobil™; Genzyme Corporation, Cambridge, MA) and granulocyte-colony stimulating factor (G-CSF) after failed previous mobilizations. A median sixfold increase in the number of circulating CD34+ cells after plerixafor treatment as compared with the baseline level was observed. An optimal CD34+ cell count for transplantation with one or two leukapheresis sessions was achieved. Mobilization using plerixafor was found to be safe with no adverse events. Therefore, the combination of G-CSF and plerixafor in children results in effective increases in peripheral CD34+ cell counts and reduces the risk of mobilization failure.
