IntroductionEven in the era of proteasome inhibitors and immunomodulatory drugs, the autologous stem cell transplantation after high-dose melphalan continues to represent a standard approach for myeloma patients in first-line therapy. Different mobilization chemotherapies before stem cell apheresis have been published while cyclophosphamide at a dose level of up to 4 g/m2 has been evaluated and is commonly applied. In contrast, lower dose levels of cyclophosphamide (e.g., 1.5 g/m2) did not result in a sufficient collection of stem cells.
