Between July 1988 and May 1990, we treated 45 women with newly diagnosed, unilateral, nonmetastatic, inflammatory breast cancer with an intensive neoadjuvant chemotherapy regimen (FEC-HD) repeated every 21 days, followed by surgery or radiation therapy. Evaluation of efficacy performed 3 to 4 weeks after at least 2 cycles showed disappearance of inflammatory signs in 91% of the patients and improvement in the remaining 9%. With regard to primary tumor and lymph nodes, there were 13 (28.9%) clinical complete responses, 30 (66.6%) partial responses, and 2 (4.5%) without change. No progressive disease was observed. Hematologic toxicity from this regimen was high with grade 4 neutropenia observed at day 14 in 100% of the patients. Retreatment at day 21 was possible in 83% of the cycles. Grade 1 or 2 infections occurred in 102 cycles out of 176 (57.9%). Grade 3 infections were seen in 9 cycles (5%). No septicemia or septic shock occurred. No toxic death occurred. After induction chemotherapy, locoregional treatment consisted of modified radical mastectomy in 39 patients and radiotherapy alone in 6. The mastectomy specimen showed no residual invasive tumor (primary tumor and lymph nodes) in 10 cases (25.6%). Two patients judged as partial responders were in fact histologic complete responders. The clinical and histological response rates observed appeared very promising. For this reason we are currently testing FEC-HD with or without GCSF in a randomized multicenter trial with correction of neutropenia, disease-free survival, and overall survival as main end points.

Serum G-CSF level was assayed in 20 burned patients (TBSA > or = 30%) 2 weeks postburn. In 11 of them plasma endotoxin was also measured. The results showed serum G-CSF level was increased in 87.5% (7/8) of burned patients with exceeding 50% TBSA and in 58.3% (7/12) of patients with 30%-50% TBSA, and in the former it was earlier increased (1-5 day postburn) than the latter (5-11 day postburn). Serum G-CSF was increased in 90% of the burned patients with wound sepsis. Increased of serum G-CSF in burned patients, especially in those exceeding 50% TBSA, indicates the occurrence of sepsis.

To investigate the effect of recombinant human granulocyte colony-stimulating factor (rhG-CSF) on sepsis, chronically catheterized conscious pigs were challenged with Pseudomonas aeruginosa (8 x 10(7) colony-forming units kg-1 h-1) for 84 h (Group A, n = 8). Group B (n = 7) also received rhG-CSF at 5 micrograms kg-1 d-1, the first dose being given 30 min before starting bacterial infusion. Two of the animals in Group A died from pulmonary failure, whereas all those treated with rh-GCSF survived. Fever, severe pulmonary hypertension and systemic hypotension--the latter accompanied at first by a transient hypodynamic, and later a hyperdynamic response--were observed in all of the animals. In Group B, however, the rise in temperature, mean pulmonary arterial pressure (at a later stage of the observation), plasma levels of tumor necrosis factor, and endotoxin were significantly less than in Group A. In the rhG-CSF-treated pigs, an initial leukopenia completely recovered within 24 h (p < .05 vs. Group A). These data suggest that rhG-CSF might be beneficial in the treatment of sepsis.

Peripheral blood progenitor cell (PBPC) autografts have a number of advantages over autologous bone marrow transplantation (ABMT) as haematopoietic support after high-dose chemotherapy in patients with breast cancer. These may include less contamination by tumour cells, reduced morbidity and mortality and additional dose escalation of chemotherapy. A dose-escalation study is described using recombinant granulocyte colony-stimulating factor (G-CSF; filgrastim) primed PBPC support and post-infusion filgrastim for patients with high-risk or metastatic breast cancer. The regimen involved the use of cyclophosphamide, thiotepa and carboplatin at five dose levels. The main problem to emerge was organ toxicity induced by chemotherapy or sepsis. Patients receiving higher levels of chemotherapy were therefore allocated or not to an additional regimen involving pentoxifylline, ciprofloxacin and dexamethasone in an attempt to inhibit tumour necrosis factor alpha (TNF-alpha) which is believed to be one of the principal mediators of chemotherapy-related organ toxicity. The incidence of bilirubin elevations, weight gain > 5% and veno-occlusive disease (VOD) was lower in patients receiving the 'anti-TNF' therapy. The simultaneous use of PBPC support and 'anti-TNF' therapy therefore allows a substantial increase in chemotherapy dosage. Further studies with larger patient numbers are required to show whether this decreased toxicity also produces increased patient survival.

The published experience of allogeneic bone marrow transplantation for primary myelofibrosis (PMF) is limited. Three patients (24-49 years) with PMF received allogeneic marrow grafts from HLA-identical sibling donors after conditioning with 110 mg/m2 melphalan and 1050 cGy total-body irradiation (TBI). Donor marrow was not depleted of T cells, and graft-versus-host disease (GVHD) prophylaxis comprised cyclosporine and methotrexate. None of the patients was splenectomized prior to the transplant. Two patients received G-CSF post-transplant to hasten neutrophil recovery. One patient died of multi-organ failure 23 days post-transplant. Hematopoietic recovery was relatively slow in the other two who had gradual resolution of the marrow fibrosis over several months. One of the two died of overwhelming pneumococcal sepsis within 2 weeks of stopping prophylactic penicillin 31 months post-transplant. The other patient is alive and well 20 months post-transplant with a Karnofsky score of 100% and no fibrosis of the marrow. We conclude that PMF is correctable by allogeneic BMT. Hematologic recovery post-transplant is slow, but counts may normalize with time without the need for splenectomy.

Over a period of 14 days a longitudinal analysis was performed on the effects of filgrastim (recombinant human granulocyte colony stimulating factor, rhG-CSF) administered to 20 postoperative/posttraumatic patients at risk of or with sepsis. The following parameters were determined: leukocyte counts, serum cytokine levels and the surface expression of functional antigens and adhesion molecules. Filgrastim (1 mu g/kg.day) was infused continuously on the first 3 days and tapered to 0.5 mu g/kg.day on the following 4 days or until discharge from the surgical intensive care unit. During infusion of filgrastim, G-CSF levels increased in 16 out of the 20 patients within 48 h. In these 16 patients, leukocyte counts increased in 15 out of 16 patients. Expression of CD64 was upregulated within 24 h. The expression of CD32 was upregulated in 8 out of 9 patients with an initial expression < 55%. LAM-1 expression was downregulated in all patients revealing an initial expression of LAM-1 > 40%. Soluble ICAM increased in 9 out of 11 patients. IL-8 decreased in all 6 patients presenting initial values of IL-8 > 90 pg/ml. IL-1RA increased in 10 patients. Filgrastim had no effect on the expression of CD14, CD16 and CD34 and on the levels of TNF-alpha and sTNF-R type I (p55). In conclusion, infusion of filgrastim in postoperative/post traumatic patients at risk of and with sepsis resulted in improved generation and function of neutrophils and appeared to counterregulate hyperactivation of proinflammatory processes.

Intensive chemotherapy has improved the prognosis of patients with AML. The success rate of relapse treatment correlates with the length of first remission. Thus early relapses and primarily refractory diseases have a grave prognosis. New chemotherapeutic regimens could be useful for those patients. Patients treated for newly diagnosed or relapsed AML with polychemotherapy regimen of the AML-BFM-studies containing induction, consolidation and high-dose cytarabine combined with mitoxantrone (HAM) and relapsed within 2 up to 31 months after the first CR entered a pilot trial, the so called IDA-FLAG regimen. This regimen includes G-CSF (day 0 up to ANC > 1000/microliter, 400 micrograms/m2.d), fludarabine (day 1-4, 30 mg/m2.d), high-dose cytarabine (day 1-4, 2000 mg/m2.d) and idarubicin (day 2-4, 12 mg/m2.d). 10 patients aged 1,8 to 28,1 years (mean = 9,6 years) having the first (n = 8) or second relapse (n = 1) of AML or an acute blastcrisis of myelodysplastic syndrome (n = 1) (FAB classification: M1/M2 = 3, M4/M5 = 5, M7 = 1, CMML = 1) received 14 courses. Overall, 7 patients achieved CR with a mean duration of 8,9 months (1-22 months), one patient showed a partial remission and two were nonresponders. 4 patients are in continuous CR for 7,5 to 22 months (mean = 13,2 months). 3 patients got a bone marrow transplantation (allogenic = 2, autologous = 1) in CR following this treatment. Toxicity was considerable, mainly bone marrow aplasia with leucopenia < 1000/microliter for 15 to 40 days (mean = 26,1 days), neutropenia < 500/microliter for 14 to 39 days (mean = 26,0 days) and thrombocytopenia < 30,000/microliter for 14 to 90 days (mean = 36,5 days). Further important side effects were fever, mucositis and pneumonia. One patient died from an fulminant aspergillus sepsis during long-term neutropenia. The sequential administration of G-CSF, fludarabine, cytarabine and idarubicin is effective in treatment of relapsed AML in childhood and an advisable option prior to allogenic or autologous bone marrow transplantation. With regard to the unfavorable prognosis of relapsed or refractory AML the toxicity of this regimen seems acceptable.

Inflammatory bowel disease is associated with mucosal neutrophil recruitment and activatation, mediated in part by arachidonic acid metabolites. G-CSF attenuates the immune response to sepsis and ameliorates glycogen storage disease Ib-related colitis. These actions may be effected through the shedding of neutrophil adhesion molecules, or inhibition of proinflammatory mediator synthesis. Immune complex colitis was used to evaluate the effect of rhG-CSF on colonic mucosal inflammation, neutrophil recruitment and the generation of eicosanoids. Immune complex colitis was induced in White New Zealand rabbits. Animals were pretreated with rhG-CSF either 24 h before induction, or at induction, with dosages of 50 and 200 micrograms/kg. rhG-CSF caused a time- and dose-dependent neutrophilia in all animals. Pretreatment with rhG-CSF resulted in increased tissue myeloperoxidase levels, despite a histologically similar mucosal polymorphonuclear cell infiltrate between treated and control colitis groups. Leukotriene B4 (LTB4) and thromboxane B2 (TXB2) dialysis fluid levels were lower in treated animals, in particular in the groups receiving two doses (LTB4: both P < 0.01; TXB2: both P < 0.01. Prostaglandin E2 (PGE2) levels in dialysis fluid of the rhG-CSF-treated animals showed no difference from controls. In this model of experimental colitis, high-dose therapy with G-CSF resulted in a marked decrease of proinflammatory mediators, but mucosal generation of the protective PGE2 was preserved. These results suggest that prolonged high-dose therapy with G-CSF may have anti-inflammatory effects in colitis.

Intensive chemotherapy with autologous bone marrow transplantation is now considered the treatment of choice for young patients with sensitive relapse of non-Hodgkin's lymphoma (NHL) but results of this procedure in older patients remain unknown. We evaluated the feasibility of two cycles of salvage therapy followed by an autologous peripheral blood stem cell (PBSC) transplantation in 13 patients aged more than 60 years (median age: 62; range 61-72) suffering from relapsed (n = 10) or refractory (n = 3) aggressive NHL. All patients had previously received first-line treatment containing doxorubicin. An association of ifosfamide, VP16, cytosine-arabinoside with or without high-dose methotrexate was used as salvage and priming therapy prior to collection of PBSC. All patients received G-CSF following salvage therapy. PBSC collection could be performed in 10 patients and yielded a median number of CFU-GM: 98.4 x 10(4)/kg (range 68-369). Nine patients underwent a transplantation using BEAM conditioning regimen. The median time to granulocyte and platelet recovery was 13 days (range respectively: 9-25 and 9-16). One patient died from sepsis after transplantation. The main adverse experience occurring after transplantation was a prolonged decline of performance status. Seven patients achieved a complete remission and one failed to respond. Three patients are still alive in CR. We conclude that PBSC collection was possible in selected patients over 60 years of age with refractory or relapsed aggressive NHL and myeloablative therapy could be used with tolerable toxicity. Hematologic recovery and organ toxicity appears to be similar to those observed in younger patients. Deterioration of performance status after transplantation is the most important factor that could limit this procedure. Further investigations are necessary to determine which patients will be able to benefit by this procedure in terms of survival and quality of life.
