    Abstract:
    BACKGROUND AIMS: Hematopoietic cell mobilization with granulocyte-colony stimulating factor (G-CSF) and plerixafor results in superior CD34+ cell yield compared with G-CSF alone in patients with myeloma and lymphoma. However, plerixafor-based approaches may be associated with high costs. Several institutions use a "just-in-time" plerixafor approach, in which plerixafor is only administered to patients likely to fail mobilization with G-CSF alone. Whether such an approach is cost-effective is unknown. METHODS: We evaluated 136 patients with myeloma or lymphoma who underwent mobilization with 2 approaches of plerixafor utilization. Between January 2010 and October 2012, 76 patients uniformly received mobilization with G-CSF and plerixafor. Between November 2012 and June 2014, 60 patients were mobilized with plerixafor administered only to those patients likely to fail mobilization with G-CSF alone. RESULTS: The routine plerixafor group had a higher median peak peripheral blood CD34+ cell count (62 versus 29 cells/μL, P < 0.001) and a higher median day 1 CD34+ yield (2.9 × 10(6) CD34+ cells/kg versus 2.1 × 10(6) CD34+ cells/kg, P = 0.001). The median total CD34+ collection was higher with routine plerixafor use (5.8 × 10(6) CD34+ cells/kg versus 4.5 × 10(6) CD34+ cells/kg, P = 0.007). In the "just-in-time" group, 40% (n = 24) completed adequate collection without plerixafor. There was no difference in mobilization failure rates. The mean plerixafor doses used was lower with "just-in-time" approach (1.3 versus 2.1, P = 0.0002). The mean estimated cost in the routine plerixafor group was higher (USD 27,513 versus USD 23,597, P = 0.01). DISCUSSION: Our analysis demonstrates that mobilization with a just-in-time plerixafor approach is a safe, effective, and cost-efficient strategy for HPC collection.
