PURPOSE: The purpose of this study was to compare the effects of filgrastim, sargramostim, or sequential sargramostim and filgrastim on CD34(+) cell yields and morbidity after myelosuppressive mobilization chemotherapy (MC). PATIENTS AND METHODS: One hundred fifty-six patients were randomized to receive filgrastim (n = 51), sargramostim (n = 52), or sargramostim for 5 days followed by filgrastim (n = 53) after MC with either cyclophosphamide and etoposide (n = 75) or paclitaxel and cyclophosphamide (n = 81). RESULTS: Compared with those who received sargramostim, patients who received filgrastim had faster recovery of an absolute neutrophil count of 0.5 x 10(9)/L or greater (a median of 11 v 14 days; P =. 0001), with fewer patients requiring RBC transfusions (P =.008), fewer patients with fever (18% v 52%; P = 0.001), fewer hospital admissions (20% v 42%; P =.013), and less intravenous antibiotic therapy (24% v 69%; P =.001). Patients who received filgrastim yielded more CD34(+) cells (median, 7.1 v 2.0 x 10(6)/kg/apheresis; P =.0001), and a higher fraction achieved 2.5 x 10(6) (94% v 78%; P =.021) and 5 x 10(6) (88% v 53%; P =.001) or more CD34(+) cells/kg with fewer aphereses (median, 2 v 3; P =.002) and fewer days of growth-factor treatment (median, 12 v 14; P =.0001). There were no major differences in outcomes between the filgrastim alone and the sequential regimens. After high-dose chemotherapy, patients who had peripheral-blood stem cells (PBSCs) mobilized withfilgrastim or the sequential regimen received higher numbers of CD34(+) cells and had faster platelet recovery (P =.015), with fewer patients (P =.014) receiving fewer platelet transfusions (P =.001) than patients receiving sargramostim-mobilized PBSCs. CONCLUSION: It was concluded that filgrastim alone or sequential sargramostim and filgrastim were superior to sargramostim alone for the mobilization of CD34(+) cells and reduction of toxicities after MC.
