Comparative Study
Retrospective comparison of mobilization methods for autologous stem cell transplantation in multiple myeloma.
The combination of cyclophosphamide and granulocyte-colony stimulating factor (G-CSF) has widely been used to mobilize hematopoietic stem cells (HSCs) for autologous stem cell transplantation (ASCT) for multiple myeloma (MM). Recently, however, alternative approaches such as G-CSF alone or etoposide followed by G-CSF have been investigated. We, therefore, retrospectively analyzed the effects of these mobilization methods on collection yield and disease outcome in ASCT for MM. ⋯ The mobilization methods did not significantly affect either the successful collection of more than 2 x 10(6) CD34-positive cells/kg or PFS after ASCT. G-CSF alone was sufficient for stem cell mobilization for a single ASCT. The optimal approach to collect HSCs in MM remains to be elucidated.
