Thirty-seven patients underwent peripheral blood stem cell (PBSC) collection from May 1994 to May 1997. Twenty-five were males and 12 were females, the median age at collection was 11.5 years (range 1-27.4) and the median weight was 38 kg (range 9-80). As mobilising chemotherapy, cyclophosphamide, etoposide, doxorubicin and cytosine arabinoside were the drugs most frequently used in association with G-CSF for a total of 47 courses. Sixty-one aphereses were performed with a median collection of CD34+ and cells/kg of 3.6 x 106 (range 0.6-31.8) and (range 0.1-1260), respectively. Minimal residual disease (MRD) was found in five of the 30 investigated aphereses. Twenty-one of the 37 patients underwent high-dose chemotherapy with autologous stem cell rescue: in seven the stem cell source was peripheral blood and bone marrow. The median duration of hospitalization was 18 days for the PBSC group and 23 days for the PBSC/ABMT group. Overall survival was 78.7% at a median follow-up of 18 months (range 2-31) and the DFS was 52% without difference depending on stem cell source. Compared to a historical group of ABMT patients, the PBSC group showed a statistical advantage in terms of neutrophils and platelet engraftment, blood and platelet requirements, and length of hospitalization. PBSC collection is a feasible procedure also in the paediatric setting providing that vascular access is adequate. As already reported, PBSC transplant results in faster engraftment and shorter hospitalization that could allow a better utilization of health financial resources. The question whether the source of stem cells could influence transplant outcome would require a prospective randomised study.
