Abstrakt:	Purpose: To compare the hematologic recovery after high-dose chemotherapy and circulating peripheral-blood progenitor-cell (PBPC) transplant between patients who received recombinant human granulocyte colony-stimulating factor (G-CSF) (treated group) and those who did not (control group). Patients and Methods: From December 1992 through June 1994, two sequential and consecutive cohorts of 20 patients each with histologically proven non-Hodgkin's lymphoma (NHL) received high-dose chemotherapy (carmustine [BCNU], cytarabine [Ara-C], etoposide and melphalan [BEAM]) followed by PBPC transplant. The first 20 patients were treated with G-CSF (5 micrograms/kg/d) after PBPC administration. Since the time of platelet and leukocyte recovery in this group was short (< 15 days), with a narrow standard deviation from the mean value, the last 20 patients were not given G-CSF. Hematologic recovery, number of febrile days, rate of documented infections, number of hospital days, duration of gastrointestinal complications, platelet and RBC transfusions, and antibiotic requirements were compared in the two groups. Results: The two groups of patients were comparable according to disease status, histology, stage, bulky disease bone marrow involvement, elevated lactate dehydrogenase (LDH) level, and median number of infused CD34+ cells and colony-forming units granulocyte-macrophage (CFU-GM). The median time to reach 0.5 x 10(9)/L and 1.0 x 10(9)/L neutrophils was 2 days shorter in G-CSF group, but this difference was not statistically significant. The median times to reach 20 x 10(9)/L and 50 x 10(9)/L platelets were, respectively, 10 and 14 days in the G-CSF group and 11 and 16 days in the control group, but again this was not statistically significant. Moreover, when considering clinically relevant end points including the number of documented infections and antibiotic requirements, platelet transfusions, gastrointestinal toxicity, and days of hospitalization, no differences were demonstrated between the two groups. Conclusions: Provided an optimal dose of circulating progenitors is infused, NHL patients transplanted with PBPC do not benefit by the administration of hematopoietic growth factors.
