Abstract Both G-CSF and GM-CSF (alone or in combination) may be used for mobilization of hematopoietic progenitor cells in patients undergoing autologous stem cell transplantation (ASCT). It has been suggested that GM-CSF use during mobilization may impact graft composition and therefore clinical outcomes. METHODS: We prospectively evaluated patients ≤ 70 years old with relapsed CD20+ NHL who were candidates for ASCT. Additional eligibility criteria included adequate marrow and organ function. Patients with history of pelvic radiation, > 3 prior chemoregimens or > 6 cycles of fludarabine chemotherapy were excluded. Patients recieved chemotherapy with ifosfamide 3.33 g/m2 daily × 3 days, etoposide 150 mg/m2 × 6 doses and rituximab (375 mg/m2 on day 1 and 1 g/m2 on day 8). Using a Bayesian adaptive randomization based on treatment outcomes, patient’s were randomized to receive G-CSF 12 μg/kg/d (Group G) or G-CSF 12 μg/kg/d plus GM-CSF 500 μg/d (Group G/GM). We assumed that the success rate for each treatment arm had a β prior distribution with mean 0.90 and variance 0.03. Cytokines started 24 hours after completion of chemotherapy and continued until completion of apheresis. RESULTS: Forty-three patients were randomized to Group G and 41 patients to Group G/GM. In each arm 1 patient withdrew consent after randomization. Baseline characteristics were similar in the 2 groups (Table 1). Both regimens were equally well tolerated. Data are presented as intent to treat analysis. Thirty-nine patients (90.7%) in Group G and 35 patients (85.4%) in Group G/GM collected ≥ 4 × 106 CD34+ cells/kg. The probability that Group G has a higher success rate than Group G/GM is 0.778. The median CD34+ cell dose collected was 10.3 × 106/kg (range, 0.1–59) and 7.5 × 106/kg (range, 0.7–73) in Groups G and G/GM respectively (P=NS). A median of 2 apheresis procedures were required in both arms. Seventy-three patients have undergone ASCT. After a median follow up time of 14.5 months (range, 0.6–38.5) in Group G and 14.0 months (range, 1.1–39.9) in Group G/GM, the 3 year PFS is 75% (95% CI 57.9–99.4) and 77% (95% CI 65–91.5) respectively (P=0.41). CONCLUSION: Our study does not support the hypothesis that using G-CSF plus GM-CSF versus G-CSF alone for progenitor cell mobilization alters graft composition in a way that impacts clinical outcomes after ASCT for NHLs.

PURPOSE To define parameters that predict for rapid engraftment after peripheral-blood stem-cell (PBSC) transplantation, progenitor thresholds, the proportion of patients who achieve these thresholds with a standardized mobilization regimen, and the factors that predict for mobilization efficiency. PATIENTS AND METHODS One hundred and one patients with pretreated lymphoma were mobilized with cyclophosphamide 1.5 g/m2 and granulocyte colony-stimulating factor (G-CSF), with the first apheresis performed when the recovery WBC count was > or = 5.0 x 10(9)/L. The relationship between the number of progenitor cells collected and patient age, sex, diagnosis, prior radiotherapy, and time since last chemotherapy was determined by multivariate analysis. The relationship between these factors, progenitor numbers returned, post-PBSC G-CSF, and hematologic recovery was performed in 81 patients following chemotherapy with carmustine (BCNU), etoposide, cytarabine, and melphalan (BEAM protocol). RESULTS No BEAM recipients had delayed neutrophil recovery beyond 28 days. Delayed platelet recovery occurred in 7.4% and minimum and optimum thresholds of 1 x 10(6) and 3.5 x 10(6) CD34+ cells/kg and 1 x 10(5) and 3.5 x 10(5) granulocyte-macrophage colony-forming cells (GM-CFC)/kg were established. Hematologic recovery was adversely affected by prior treatment with mini-BEAM, and neutrophil recovery was accelerated by post-PBSC G-CSF. The minimum GM-CFC threshold was achieved with a single apheresis in 83% of patients and in 90% with two aphereses. The optimal threshold was achieved with two leukaphereses in 69% of patients. Prior radiotherapy adversely affected mobilization. CONCLUSION Hematopoietic recovery following PBSC is dependent on progenitor-cell number infused and affect of previous chemotherapy on progenitor quality. Progenitor-cell mobilization is adversely affected by prior radiotherapy. The minimum threshold of GM-CFC required is achieved in most patients with a single apheresis, but an optimal collection usually requires at least two harvests.
