    Abstract:
    The mobilizing potential and therapeutic activity of ifosfamide/vinorelbine-containing regimens with G-CSF support were explored in patients with pretreated malignant lymphomas. Ten patients with non-Hodgkin's lymphoma (NHL) received ifosfamide and vinorelbine, and 17 with Hodgkin's disease (HD) received ifosfamide, vinorelbine and gemcitabine (IGEV regimen), as induction chemotherapy before high-dose chemotherapy (HDT) with peripheral blood stem cell (PBSC) support. Most of the patients had been heavily pretreated with various chemotherapy regimens +/- radiotherapy. The target yield was > or =3 x 10(6) CD34+ cells/kg of body weight in order to support the subsequent myeloablative chemotherapy. The optimal PBSC harvest occurred on days 11 and 12, with no difference in CD34+ cell mobilization kinetics between the ifos- famide/vinorelbine and IGEV regimens. The median number of CD34+ cells/kg body weight collected was 10.9 x 10(6) (range 1.76-61.1 x 10(6)). The median total CD34+ cell/microl, CFU-GM and white blood cells (WBC) for all individual collections was 81.5/microl, 10 x 10(4)/kg, and 17 900/microl, respectively. The target yield of CD34+ cells was reached in 24 of 27 patients. Hematological side-effects were acceptable and no treatment-related hospitalizations or toxic deaths occurred. Fifteen patients have so far received high-dose therapy and PBSC reinfusion with rapid engraftment. These results confirm that ifosfamide and vinorelbine-based chemotherapy regimen with G-CSF support can be successfully and safely used to mobilize PBSCs.
