2008 WHO Myeloid and Lymphocytic Tumor Diagnostic Criteria

patients with refractory /relapsed lymphoma received high-dose etoposide for hematopoietic stem cell (HSC) mobilization.All patients received high-dose etoposide 20-25 mg/kg/d intravenously for two consecutive days followed by rhG-CSF10ug/kg/day subcutaneously at 48 hours after chemotherapy; rhG-CSF was continued until the end of harvesting for HSCs/HPCs. Peripheral blood counts were performed daily for all patients following the initiating of rhG-CSF. Leukapheresis was performed when peripheral blood white blood count exceeded 4×109/L with blood cell The harvested cells reached at least 2*108/kg for mononuclear cells and/or 2*106/kg for CD34+ cells with once to twice leukapheresis. The final product was kept frozen in liquid nitrogen.Auto-PBSCT
