Fourteen patients with relapsed Hodgkin's disease responded to a salvage therapy with Dexa-BEAM (dexamethasone, BCNU, etoposide, Ara-C and melphalan). In seven patients a continuous i.v. infusion with recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) was started subsequent to Dexa-BEAM (+rhGM-CSF) while the other seven patients received no hemopoietic growth factor (-rhGM-CSF). It was our objective to study the impact of rhGM-CSF on the collection of blood-derived hemopoietic stem cells in patients with extensive prior chemo- and radiotherapy not eligible for marrow harvest. Compared to baseline, we observed a significant increase of colony-forming units granulocyte-macrophage (CFU-GM) in the peripheral blood of patients receiving rhGM-CSF (p less than 0.05). On average, the yield of total nucleated cells and CFU-GM collected per single leukapheresis was 2.2 and 2.4-fold higher in the rhGM-CSF-treated patients respectively (p less than 0.05). With rhGM-CSF the interval from the start of chemotherapy to the end of blood stem cell collection could be reduced by 6 days (p less than 0.05). Following the CBV pretransplant regimen (cyclophosphamide, BCNU, etoposide), the reinfusion of rhGM-CSF-exposed stem cells resulted in a shorter time of leukocyte recovery (p less than 0.05). The number of CFU-GM/kg body weight transplanted was found to be predictive for the time of neutrophil recovery (p less than 0.05). In patients with bone marrow hypoplasia or fibrosis, rhGM-CSF as part of an effective salvage therapy improves the collection of blood stem cells that are capable of restoring hemopoiesis after high-dose pretransplant therapy.

Colony-stimulating factor 1 (CSF-1) is a cytokine involved in hematopoiesis and perhaps more importantly in the early stages of immunological defense mechanisms. Although numerous studies of in vitro CSF-1-producing cells have been published, in vivo data is totally lacking. According, we performed immunohistochemical detection of CSF-1-positive cells on frozen sections of reactive lymphadenitis (three cases) and Hodgkin's disease (13 cases) lymph node biopsies, using as antibody a highly specific polyclonal rabbit antiserum prepared in our laboratory. Endothelial cells from high endothelial venules and most fibroblasts were positive in all cases (reactive lymphadenitis and Hodgkin's samples), and most lymphocytes in interfollicular T cell areas showed faint granular positivity in reactive lymphadenitis lymph nodes. Hodgkin and Reed-Sternberg cells were positive in all cases tested, although staining intensity was highly variable and the percentage of positive cells differed from case to case. These data from in vivo biopsies confirm previous results for in vitro CSF-1 production by endothelial cells, fibroblasts, T lymphocytes, and Hodgkin cell lines. They are consistent with the role of this cytokine in immune response and raise the question of its significance in Hodgkin's disease.

Nine patients with relapsed or refractory Hodgkin disease or non-Hodgkin lymphoma underwent peripheral stem cell autografting because of a history of marrow involvement with visible lymphoma. Peripheral stem cells were collected during a process of unstimulated leukapheresis. Recovery to a neutrophil count of 0.1 x 10(9)/L was seen at a median of 14 days compared with a median of 18 days for a concurrent series of marrow recipients (P = .12). Recoveries to a neutrophil count of 0.5 x 10(9)/L and a platelet count of 50 x 10(9)/L occurred at medians of 25 days and 28 days, respectively. These figures are not significantly different from those obtained in the marrow recipients. Of the original nine patients, six are surviving free of disease progression or relapse at a median of 240 days posttransplant. Two patients died of transplant-related complications and one relapsed 250 days post-transplant. All surviving patients remain independent of transfusions and six have attained almost complete hematological reconstitution. Although administration of cytotoxic therapy and granulocyte-macrophage colony-stimulating factor (GM-CSF) may enhance the yield of early progenitor cells during leukapheresis, unstimulated leukapheresis results in a stem cell product capable of rapidly restoring and sustaining marrow function even after multiple courses of intensive "salvage" therapy. Additional follow-up will be needed to determine whether preliminary survival figures continue to compare favorably with those of patients with similar extramedullary disease states undergoing marrow transplants.

In the present study, we show by Northern blot analysis and enzyme linked immunosorbent assay that the Hodgkin's disease (HD)-derived cell lines HDLM-2 and KM-H2 express a variety of cytokine genes either constitutively or upon induction with phorbol ester 12-O-tetradecanoylphorbol-13-acetate. Cytokine genes expressed by HD-derived lines include granulocyte-macrophage colony-stimulating factor (CSF), macrophage-CSF, interleukin (IL)-1-alpha, IL-3, IL-5, IL-6, IL-8, leukemia inhibitory factor, tumor necrosis factor-alpha, tumor necrosis factor-beta, and transforming growth factor-beta, while transcripts and the corresponding proteins for granulocyte-CSF, IL-1-beta, IL-2, IL-4, IL-7, IL-10, and the JE/macrophage chemoattractant and activating factor gene were not detectable in cytoplasmic RNA and culture supernatants obtained from both lines. In addition, IL-2 receptor (R) p55 and macrophage-CSF R (c-fms) genes were expressed by both lines. HDLM-2, but not KM-H2 cells, exhibited the IL-6 R p80 and the IL-2 R p75 chain. Analysis of nuclear proteins that bind to oligonucleotides containing the consensus sequences of the transcription factors activation protein 1, nuclear factor (NF) kappa B, and NFAT 1 revealed a pattern for HD lines resembling that of activated T-cells: HDLM-2 and KM-H2 cells constitutively expressed NF binding to the NF of activated T-cells (type 1), previously described to be T-cell specific. In addition, NF kappa B-binding proteins obtained from both lines showed, in electrophoretic mobility shift assays, the same migration pattern as T-cell-derived proteins but differed from monocyte- and B-cell-derived proteins. UV cross-linking experiments confirmed that NF kappa B-binding proteins of M(r) 85,000, 75,000, and 50,000/55,000 were detectable in nuclear extracts obtained from T-cells and both HD lines, while monocytes and B-cells displayed the M(r) 50,000/55,000 and 75,000 NF kappa B complex only. Both HD lines also constitutively expressed transcripts for c-fos and c-jun, which are involved in heterodimeric formation of the transcription factor activation protein 1, as well as for the NF kappa B/KBF1 gene.

We have previously shown that total T cells derived from lymph nodes (LN) involved by Hodgkin's disease (HD) secrete higher levels of colony-stimulating activity than total T cells present within benign hyperplastic (BH) LN and B-non-Hodgkin's lymphoma (B-NHL) LN, suggesting that T cells with particular properties accumulate in HD LN. To further characterize this T-cell population, we have quantified production of both granulocyte-macrophage colony-stimulating factor (GM-CSF) and macrophage colony-stimulating factor (M-CSF) production in a total of 98 T-cell clones (TCC) derived from CD25+ activated T cells present in HD LN; TCC derived from CD25+ T cells obtained from B-NHL LN(101 TCC), BH LN(95 TCC), and peripheral blood (PBL; 38 TCC) of healthy donors were used as controls. HD LN were characterized by the presence of an elevated number (44%) of TCC producing particularly high titers of both GM-CSF and M-CSF, whereas only a minority of such TCC was found in control groups (10% in B-NHL, 16% in BH, 8% in PBL). These observations support the hypothesis of a selection of T-cell families with particular properties occurring in contact with Reed-Sternberg (RS) cells. According to the biological properties of GM-CSF and M-CSF, it seems reasonable to suggest the involvement of this particular subset of T cells in the granulomatous process, the peripheral blood polynucleosis, and in the paracrine growth of RS cells.

Five patients with resistant non-Hodgkin lymphoma (NHL) were given granulocyte-macrophage colony-stimulating factor (GM-CSF, 250 micrograms/m2 daily) after the BEAM pretransplant chemotherapy regimen (carmustine 300 mg/m2, etoposide 1.2 g/m2, cytarabine 800 mg/m2, melphalan 140 mg/m2) because persistent lymphoma cell infiltration of the bone marrow precluded autologous bone-marrow transplantation (BMT). In three patients full haemopoietic reconstitution occurred, with similar kinetics to that seen after autologous BMT. The other two patients died without sustained haemopoietic recovery. GM-CSF may replace autologous BMT in highly selected cases of NHL with progressive disease and bone-marrow involvement.

Recombinant granulocyte colony-stimulating factor (rG-CSF) primed the ability of human neutrophils to generate increased levels of reactive oxidants in response to fMet-Leu-Phe, and also resulted in an increased rate of protein biosynthesis which was similar to that induced by granulocyte-macrophage colony-stimulating factor. However, rG-CSF reduced the chemotactic activity of neutrophils in response to endotoxin and did not result in an enhanced rate of killing of Staphylococcus aureus. rG-CSF was administered to patients after high dose chemotherapy and autologous bone marrow transplantation for the treatment of either Hodgkin's disease or multiple myeloma. This cytokine decreased the period of neutropenia following such treatment. Neutrophil function in two patients, measured seven days after the final administration of rG-CSF, was severely impaired as indicated by a greatly decreased ability to generate reactive oxidants. However, seven days later (i.e. 14 days post-therapy), the functional activity of the neutrophils from these patients had returned to normal. These data indicate that assays of neutrophil function together with morphological assessment of neutrophil numbers and maturity should be performed in order to evaluate the immune status of patients undergoing such therapy.

In 20 patients with non-Hodgkin lymphoma or breast cancer, high-dose cyclophosphamide induced, during the post-nadir period of rapid leucocyte recovery, on median day 19 about a 30-fold increase in the peak concentration of granulocyte-macrophage (CFU-GM) and erythroid (BFU-E) colony-forming cells, and an even higher increase in the more immature pluripotent progenitors (CFU-Mix, 72-fold). After infusion of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF), peak concentration was reached earlier (median day 15) and with further enhancements (159, 116 and 283-fold respectively, in the number of CFU-GM, BFU-E and CFU-Mix). Most CFU-GM were immature, lacking the differentiation antigen CD15, and gave rise to large myeloid colonies, reflecting a high proliferative capacity of the founder cells. Very immature maphosphamide-resistant progenitors were detectable. The marked expansion in the circulating pool was predictable and reliable, allowing harvesting, after two or three leukaphereses, of sufficient haematopoietic progenitors for autologous bone-marrow reconstitution.

Patients with relapsed Hodgkin's disease who respond to salvage therapy are successfully treated with cyclophosphamide, carmustine (BCNU), and etoposide (VP-16) (CBV) followed by autologus bone marrow transplantation (ABMT). Because of heavy pretreatment including radiation to the pelvic site, marrow harvest was not feasible in those patients. We therefore used blood-derived hemopoietic precursor cells as an alternative stem-cell source to rescue them after superdose chemotherapy. Hemopoietic precursor cells were mobilized into the peripheral blood either by chemotherapeutic induction of transient myelosuppression followed by an overshooting of blood stem-cell concentration, or by continuous intravenous (IV) granulocyte-macrophage colony-stimulating factor (GM-CSF) administration. The median time to reach 1,000 WBC per microliter, 500 polymorphonuclear cells (PMN) per microliter, or 20,000 platelets per microliter was 10, 20.5, and 38 days, respectively, for 50% of all patients. The platelet counts of two patients never dropped below 20,000/microL following autologous blood stem-cell transplantation (ABSCT), whereas two other patients had to be supported with platelets for 75 and 86 days posttransplant until a stable peripheral platelet count of 20,000/microL was attained. Among the 11 assessable patients, seven are in unmaintained complete remission (CR) at a median follow-up of 318 days. This is a first report on a series of ABSCTs in patients with advanced Hodgkin's disease proving that, despite prior damage to the marrow site, the circulating stem-cell pool is still a sufficient source of hemopoietic precursor cells for stem-cell rescue.

To investigate effects of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) on lymphoid cells in vivo, we monitored changes in absolute lymphocyte counts, plasma concentrations of soluble interleukin-2 receptor (sIL-2R) and soluble cytotoxic/suppressor (sCD8) antigens, and phenotypic changes of surface membrane antigens of peripheral mononuclear cells from 14 patients with malignant lymphoma treated with rhGM-CSF. Eight of the 14 patients had relapsed or had refractory non-Hodgkin's lymphoma (NHL) and received rhGM-CSF after intensive chemotherapy with novantrone (NO) and high-dose Ara-C (AC) (NOAC) as salvage regimen. Six other patients with NHL or Hodgkin's disease (HD) were in complete remission and treated with rhGM-CSF to enhance peripheral hematopoietic progenitor cell harvest for autografting. An increase in absolute lymphocyte count at the zenith of leukocyte elevation and a drastic increase in concentration of sIL-2R from a median of 565 U/mL to 6,700 U/mL on rhGM-CSF infusion were found in all patients. There was also a moderate increase in sCD8 levels from a median of 277 U/mL to 470 U/mL. Ten patients were available for serial studies of phenotypic changes in surface membrane antigens. A significant increase in CD25+ (IL-2R+) (P = .0020) and CD4+ (P = .0137) lymphocytes was observed in all patients, but no significant change in CD3+, CD8+, TCR delta 1+, or CD19+ cells. Elevations in absolute lymphocyte counts or in concentrations of sIL-2R or sCD8 were not observed in four other patients during recovery from intensive chemotherapy without rhGM-CSF support. Our results provide evidence that administration of rhGM-CSF might activate lymphocytes in vivo. The impact of this activation on the remission rate and duration, as well as survival in patients with NHL, warrants further investigation.
