Popis: Background and Objectives: Continuous-flow and intermittent-flow blood cell separators (CFCS and IFCS) are both used to collect stem cells from the blood to rescue patients undergoing myeloablative treatment for cancer. Materials and Methods: We designed a study to compare the collection efficiency of the two systems. The continous-flow Cobe Spectra and the intermittent-flow Haemonetics MCS-3P were used to collect cells on consecutive days from 9 patients mobilised with G-CSF with or without chemotherapy. Blood obtained before leukapheresis and the leukapheresis product were analysed for their content of red and white cells, platelets, CD34-positive cells, GM-CFC, CFC-E, and BFU-E. An extraction ratio was calculated. Results: We found that the CFCS extracted about 4 times more mononuclear cells per unit time, 3 times more CD34-positive, and 4 times more clonogenic cells than the IFCS. The subject acceptability of the two systems was similar. Conclusion: The CFCS is a more efficient system for stem cell collection. IFCS requires a longer harvesting time for the same result.
