DA-EPOCH Chemotherapy Combined with G-CSF Effectively Mobilizes Autologous PBHSC in NHL Patients / 中国实验血液学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the effect of the DA-EPOCH chemotherapy combined with G-CSF and the CTX therapy with G-CSF on mobilizing and collecting the peripheral blood hematopoietic stem cells and the later hematopoietic recovery.</p><p><b>METHODS</b>Forty patients accepted mobilization and collection of peripheral blood stem cells(PBSC) after treated by CTX+G-CSF and DA-EPOCH+G-CSF therapy respectively, and were treated by auto-transfusion after BEAM pre-regimen. The mobilization efficacy, adverse effects and hematopoietic recovery after autologous transplantation were analyzed retrospectively.</p><p><b>RESULTS</b>During the CTX+G-CSF mobilization, only one patient achieved the white blood cell(WBC) at 0.8×10/L, while the others were with the lowest WBC level above 2.0×10/L. The platelet counts were all normal with the exception of 3 cases at 80×10/L. The median percentage of CD34cells in one period of collection was 0.99(0.35-1.30)%. The median MNC was (3.80±2.05)×10. The cumulative total of mononuclear cell was (5.84±2.48)×10/kg, and the median CD34cell count was 3.84(3.91-6.5)×10/kg. During the DA-EPOCH+G-CSF mobilization, the peripheral WBC count of patients were decreased to the lowest level at (0.2-1.4)×10/L. The platelet counts were all above 40×10/L except for 1 case in which the platelet count was reduced to 8×10/L. The median percentage of CD34cells in one period of collection was 0.85(0.34-1.2)%. The median MNC was (3.68±1.56)×10. The cumulative total of mononuclear cells was (6.01±2.26)×10/kg, and the median CD34cell count was 4.44(2.7-7.10)×10/kg. There were no statistical differences between the 2 groups in the median percentage of CD34cells, the median MNC, the cumulative total of mononuclear cells and the median CD34cell counts (P>0.05). The average acquired time for granulocyte engraftment was 10.00(9.00-11.00) days, and for platelet engraftment was 12.50(11.00-17.25) days, with no statistical difference(P>0.05). No death occurred during the process of transplantation.</p><p><b>CONCLUSION</b>DA-EPOCH therapy combined with G-CSF can effectively mobilize the peripheral blood hematopoietic stem cells in NHL patients with higher safety and lower price, and proves to be worth recommending in clinical use.</p>
