Conflicting results have been reported regarding the effect of various growth factors on the mobilization of natural killer (NK) cells and dendritic cells in patients undergoing stem cell mobilization for autotransplantation. We compared the extent of mobilization of NK cells and dendritic cells in non-Hodgkin's (NHL) patients undergoing mobilization with granulocyte colony-stimulating factor (G-CSF), granulocyte-macrophage (GM)-CSF, or GM-CSF followed by G-CSF. Overall, 35 patients were studied. NK cells and dendritic were quantitated by flow cytometry. NK cells were defined as the sum of CD56(+) cells and CD56/CD16(+) cells. Dendritic cells were defined as the sum of CD80(+) and CD80(+)/CD14(+) cells. NK activity was determined by by microcytotoxicity assay. NK activity correlated well with the total amount of CD56(+) cells mobilized to the peripheral blood. Patients in the three arms of the study mobilized similar amounts of NK cells and NK activity, and patients who lacked NK activity in the peripheral blood, before mobilization, lacked NK activity in their apheresis collections. In contrast to NK cell mobilization, mobilization of dendritic cells/kg was three- to five-fold higher in patients mobilized with GM-CSF-containing regimens compared to patients mobilized with G-CSF alone. We conclude that GM-CSF-containing mobilization regimens are superior for dendritic cell mobilization but similar in the mobilization of NK cells. Therefore, we recommend using GM-CSF-containing regimens for patients undergoing ex vivo or in vivo manipulation of dendritic cells.

We explored the efficacy of the IGEV regimen (ifosfamide, gemcitabine, vinorelbine and prednisone) combined with a fixed dose of lenograstim (263 mug/day) to mobilize peripheral blood stem cells (PBSCs) in 90 Hodgkin's lymphoma patients. The median total CD34+ cells/mul peak, colony-forming units granulocyte-macrophage and white blood cells for all individual collection sets were 85/mul, 12 x 10(4)/kg and 20 700/mul, respectively. An adequate number of CD34+ cells (more than 3 x 10(6) or 6 x 10(6) CD34+ cells/kg depending on whether single or tandem high-dose chemotherapy was used) were collected in 89 out of 90 (98.7%) mobilized patients, whereas the only failure reached 2.3 x 10(6) CD34+ cells/kg. The median CD34+ cell collections were 11 x 10(6)/kg (range 2.3-39 x 10(6)/kg) and 10 x 10(6)/kg (range 6-22.0 x 10(6)/kg) with a median of 1 and 2 leukaphereses for patients eligible for single high-dose treatment and for candidates for tandem transplant, respectively. Target yields were reached in 71.43 and 49.09% and additionally in 17.14 and 43.64% of cases after the first and second apheresis procedures, respectively. Hematological and non-hematological side effects were acceptable, and no toxic deaths occurred. Thirty-four patients received a single and 47 received tandem transplantation with rapid engraftment. These results confirm that the IGEV regimen with lenograstim support can be used successfully and safely to mobilize PBSCs.

The levels of spontaneous and mitogen-induced production of pro- and anti-inflammatory cytokines were studied in patients with chronic lymphoid leukemia, non-Hodgkin's lymphocytic lymphomas, and multiple myeloma during the course of chemotherapy. Cytokine concentrations varied within a great range and did not conform to the normal distribution law. The levels of granulocyte and granulocyte-macrophage CSF were high during the debut, progress, and remission of the lymphoproliferative diseases. Imbalance of a wide spectrum of pro- and anti-inflammatory cytokines was observed during the debut and progress of the lymphoproliferative diseases, more often in chronic lymphoid leukemia and non-Hodgkin's lymphocytic lymphomas than in multiple myeloma.
