Abstract

High-dose chemotherapy and autologous stem cell transplantation (SCT) have become an effective care for many patients with hematological malignancies. Harvesting the stem cells is one the most important parts of SCT. The two most commonly used mobilization regimens are the use of granulocyte colony-stimulating factor (G-CSF) or G-CSF plus chemotherapy. However, about 10-30% of patients are unable to collect enough cells to support HSCT due to previous chemotherapies, radiation, marrow involvement or fibrosis. In multiple myeloma patients, it is hard to collect enough stem cells when the bone marrow is extensively involved. Plerixafor has emerged as a novel mobilizing agent and its efficacy has been shown in two phase III studies. Considering the importance of autologous SCT in patients with multiple myeloma, we report the first successful Iranian experience at Tehran Taleghani bone marrow transplantation center using plerixafor to mobilize stem cells in a patient with refractory multiple myeloma with extensive bone marrow involvement who failed mobilization with G-CSF.
