Plerixafor use in patients with previous mobilization failure: A multicenter experience

Abstract

Plerixafor in conjunction with G-CSF (G–P) is an effective strategy for hematopoietic stem cell mobilization in patients with previously failed mobilization attempt. Here we report our results with G–P among patients with at least one mobilization failure with G-CSF alone (G) or G-CSF plus chemotherapy (G–C). The study included 20 consecutive patients with lymphoma and myeloma from five centers. In 14 (70%) patients, a minimum of 2×106/kg CD34+ stem cells were collected and 16 out of 20 patients (80%) were able to proceed to ASCT. Our study indicates that plerixafor can safely rescue patients with a history of mobilization failure.
