High - dose chemotherapy with autologous transplantation of peripheral blood progenitor cells is a possible treatment for the high-risk oncology patients. Peripheral blood stem cells (PBSC) have been separated on Autotransfusion detachment in IKEM Prague since November 1996. By the end of September 2002, 64 patients (47 man and 17 women) with solid tumours were indicated for collections. PBSC separations were commenced at value CD 34+ peripheral blood cells over 20 x 103/ml after mobilization by combination of chemotherapy with growth factors - G-CSF (Neupogen in dose 15 µg/kg/day). There were 247 separations provided on the whole on the Haemonetics MCS 3p and MCS+ separators, respectively. Both types of separators were compared. All the patients were given extract PBSC extracts back: 40 patients after the application of high – dose chemotherapy and 24 patients after the application of only intensificated therapy. This procedure appears to be very perspective for this group of patients in the future.
