Abstract

Peripheral blood cell (PBC) rescue has become the mainstay for autologous transplantation in patients with lymphoma, multiple myeloma, and solid tumors. Different methods of hematopoietic progenitor cell (HPC) mobilization are in use without an established standard. Forty-seven patients with relapsed or refractory lymphoma received salvage chemotherapy and were randomized to have HPC mobilization using filgrastim [granulocyte-colony-stimulating factor (G-CSF)] alone for 4 days at 10 microg/kg per day (arm A) or cyclophosphamide (5 g/m(2)) and G-CSF at 10 microg/kg per day until hematologic recovery (arm B). Engraftment and ease of PBC collection were primary outcomes. All patients underwent the same high-dose chemotherapy followed by reinfusion of PBCs. There were no differences in median time to neutrophil engraftment (11 days in both arms; P =.5) or platelet engraftment (14 days in arm A, 13 days in arm B; P =.35). Combined chemotherapy and G-CSF resulted in higher CD34(+) cell collection than G-CSF alone (median, 7.2 vs 2.5 x 10(6) cells/kg; P =.004), but this did not impact engraftment. No differences were found in other PBC harvest outcomes or resource utilization measures. A high degree of tumor contamination, as studied by consensus CDR3 polymerase chain reaction of the mobilized PBCs, was present in both arms (92% in arm A vs 90% in arm B; P = 1). No differences were found in overall survival or progression-free survival at a median follow-up of 21 months. This randomized trial provides clinical evidence that the use of G-CSF alone is adequate for HPC mobilization, even in heavily pretreated patients with relapsed lymphoma.
