Abstract:
Objective:To investigate the efficiency and pharmacoeconomics of pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) for mobilization of peripheral blood stem cells (PBSCM) in patients with multiple myeloma (MM).Methods:The data of 91 patients with newly treated MM who were hospitalized in the First Hospital of Jilin University and Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College from January 2015 to October 2017 were retrospectively analyzed. According to the patient's wishes, a high-dose chemotherapy combined with subcutaneous injection of PEG-rhG-CSF or recombinant human granulocyte colony-stimulating factor (rhG-CSF) was used for stem cell mobilization in 42 and 49 patients, respectively. The number of mononuclear cells (MNC) and CD34 + cells collected after mobilization, the maximum absolute neutrophil count (mANC), the cost of mobilization, and the engraftment time of white blood cells and platelets after transplantation were compared between the two groups. Results:The median number of MNC collected after mobilization in the PEG-rhG-CSF group and rhG-CSF group were 5.86×10 8/kg [(1.08-24.54)×10 8/kg] and 6.61×10 8/kg [(0.83-33.80)×10 8/kg], and the difference was not statistically significant ( U = 883.00, P = 0.245); while the median number of CD34 + cells collected after mobilization in the PEG-rhG-CSF group was higher than that in the rhG-CSF group [5.56×10 6/kg (0.94-19.90)×10 6/kg and 4.82×10 6/kg (1.12-14.61)×10 6/kg], and the difference was statistically significant ( U = 732.00, P = 0.038). The median number of mANC during mobilization in the PEG-rhG-CSF group was lower than that in the rhG-CSF group [20.50×10 9/L (7.26-61.30)×10 9/L and 32.08×10 9/L (6.92-69.99)×10 9/L], and the difference was statistically significant ( U = 490.00, P = 0.001). After autologous stem cell transplantation (ASCT), the time-to-recovery of white blood cell count (WBC) to 1.0×10 9/L in the PEG-rhG-CSF group was shorter than that in the rhG-CSF group [(11.59±1.98) d vs. (12.93±2.83) d], and the difference was statistically significant ( t = -2.395, P = 0.019), and the time-to-recovery of platelet count (Plt) to 20.0×10 9/L in the PEG-rhG-CSF group was also shorter than that in the rhG-CSF group [(12.86±2.62) d vs. (14.80±5.47) d], but the difference was not statistically significant ( t = -1.749, P = 0.085). The total mobilization cost of the PEG-rhG-CSF group was not statistically different from that of the rhG-CSF group [(21 405.47±7 365.98) yuan vs. (22 976.83±10 264.34) yuan, t = -0.721, P = 0.474]. Conclusions:PEG-rhG-CSF combined with high-dose chemotherapy is an effective option for PBSCM in MM patients, and its mobilization cost is equivalent to rhG-CSF. Therefore, PEG-rhG-CSF may be a better choice for PBSCM in MM patients.
