Abstract: | Autologous transplantation is the standard of care for transplant-eligible patients with multiple myeloma. Toward making this treatment accessible in developing countries, there are significant challenges like resource constraints and access to cryopreservation facilities. We performed a retrospective analysis of patients with multiple myeloma who underwent autologous transplantation using granulocyte colony-stimulating factor (G-CSF)-mobilized non-cryopreserved grafts at our institution from January 1995 to December 2014. Peripheral blood stem cells (PBSCs) were harvested over 1 to 2 days after G-CSF mobilization. After apheresis, PBSCs were stored at 4°C in a blood bank refrigerator for up to 72 hours. During the study period, 224 patients with multiple myeloma underwent autologous transplantation using G-CSF–mobilized non-cryopreserved grafts. The number of days of stem cell harvest was 1 in 91 patients (40.6%) and 2 in 133 patients (59.4%). The median CD34 cell dose was 4.87?×?106/kg (range, 1.15 to 23.7). All patients except 1 engrafted. The median time to neutrophil engraftment was 12 days (range, 9 to 22). The median time to platelet engraftment was 17 days (range, 10 to 44). In a resource-limited setting, the use of G-CSF–mobilized non-cryopreserved grafts results in adequate engraftment for most patients with multiple myeloma undergoing autologous stem cell transplantation. |
