G-CSF-mobilized peripheral blood stem cells (PBSCs) are frequently used for autologous and allogeneic hematopoietic cell transplantation. Although the COBE Spectra® Apheresis system has been commonly used, Spectra Optia®, a novel automatic interface-controlled apheresis system, became available at Okayama University Hospital in July 2011. We retrospectively analyzed a total of 73 cases of apheresis, 49 performed with the COBE system and 24 with the Optia system, for 51 autologous and 22 allogeneic PBSC samples collected between January 2011 and June 2012. For autologous PBSCs, total product volume and RBC contamination of products were significantly lower in the Optia group than in the Spectra group. For allogeneic PBSCs, total WBC counts and platelet contamination, as well as total product volume and RBC contamination, were lower in the Optia group than in the Spectra group, despite MNC collection efficacy and CD34+ cell numbers being similar in both groups for autologous and allogeneic PBSCs. Automatic apheresis with the Spectra Optia system is patient- and user-friendly, and has a similar collection efficacy to that of the COBE Spectra system.
