title: [Mobilization of autologous peripheral blood stem cells by cyclophosphamide and recombinant human granulocyte colony-stimulating factor(rhG-CSF)].
abstract: OBJECTIVE
  To observe the effect of cyclophosphamide (CTX) and recombinant human granulocyte colony-stimulating factor(rhG-CSF, Filgrastim) on autologous peripheral blood stem cells (APBSC) mobilization.
  
  
  METHODS
  CTX (3.7 +/- 0.2) g/m2 was intravenously injected the first day. rhG-CSF (4.5 +/- 0.6) micrograms.kg-1.d-1 was injected subcutaneously from the day of white blood cell (WBC) nadir to the day before the end of APBSC harvest. APBSC harvest was started when WBC > 2.5 x 10(9)/L and finished when accumulated mononuclear cells (MNC) of APBSC > 5 x 10(8)/kg. CFU-GM, BFU-E culture and CD34+ cells detection of the APBSC was performed.
  
  
  RESULTS
  Twenty cases underwent the APBSC mobilization. The nadir of WBC was (1.1 +/- 0.5) x 10(9)/L at day (9 +/- 1). rhG-CSF was injected from day (10 +/- 1) and continued for (6 +/- 1) days. APBSC harvest began on day (13 +/- 1) and continued for (4 +/- 1) days. Accumulated MNC harvest was (8.4 +/- 1.9) x 10(8)/kg, CFU-GM (18.7 +/- 10.3) x 10(4)/kg, BFU-E (18.5 +/- 8.7) x 10(4)/kg, and CD34+ cells (20.9 +/- 5.7) x 10(6)/kg. No severe toxicity was observed. Hematopoietic reconstitution was very well in 18 patients received the APBSC transplantation.
  
  
  CONCLUSIONS
  CTX combined with rhG-CSF was a safe and highly effective method for APBSC mobilization.
