Özet

Autologous stem cell transplantation (ASCT), supported by high-dose chemotherapy, is the prevalent option for multiple myeloma (MM) treatment in candidates suitable for transplantation. Although granulocyte colonystimulating factor (G-CSF) supported cyclophosphamide (CY) is used as the pre-ASCT mobilization regimen, there is no consensus on the optimal dosage of CY. Thus, in this study, we examined the results of 47MM patients, who underwent ASCT after mobilization with intermediate (ID) or low-dose (LD) CY treatment supported with G-CSF. As the mobilization regimen, we used ID (2.4 g/m(2)) of CY in 22 patients, and LD (1 g/m(2)) of CY in 25 patients. Adequate doses of CD34+ cells were collected in both groups. At the same time, febrile neutropenia was observed to be less common in patients in the LD-CY group. Additionaly 96% of patients in LDCY group did not need to be hospitalized during the mobilization. In conclusion, we think that mobilization with LD-CY and G-CSF is advantageous since it results in a sufficient amount of stem cells in addition to being advantageous in terms of patient safety and cost.
