A 41-year-old male complaining of fever and left shoulder pain was admitted to our hospital for further examination of an abnormal shadow on chest X-ray film. His laboratory data on admission showed marked leukocytosis and elevation of serum alkaline phosphatase. The diagnosis of large cell carcinoma of the lung was made by percutaneous biopsy and he was staged clinically as T3N0M0. Chemotherapy including CDDP and VDS resulted in resolution of symptoms and normal laboratory data. After three courses of chemotherapy, he underwent left upper lobectomy with chest wall resection. Pathological diagnosis of the resected tumor was large cell carcinoma with giant cells, and he was staged postoperatively as T3N0M0. Since colony stimulating activity was demonstrated in both homogenate of tumor cells and tumor conditioned medium, and preoperative serum granulocyte colony-stimulating factor (G-CSF) was 105 pg/ml, we concluded that leukocytosis in this patient was caused by G-CSF produced by tumor cells. The patient was in good health two years after surgery with no signs of recurrence.

We established a human carcinoma cell line (KHC 287) from a patient with large-cell-typing lung carcinoma associated with marked leukocytosis. The culture supernatant of KHC 287 cells promoted granulocytic colony formation of human bone-marrow cells in semi-solid culture. Colony formation was almost completely suppressed by treatment of the supernatant with a monoclonal anti-granulocyte colony-stimulating factor (G-CSF) antibody. Not only G-CSF but also interleukin-1 alpha (IL-I alpha), IL-I beta and IL-6 were detected in the culture supernatant by an ELISA method. Northern blot analysis of KHC 287 cells revealed distinct expression of these cytokine genes. Southern blot hybridization of KHC 287 DNA showed 20- and 40-fold co-amplification of c-myc and c-ki-ras, respectively. The chloramphenicol acetyl transferase (CAT) activity was distinctly enhanced in the KHC 287 cells which were transfected with the 360 bp upstream region of G-CSF gene inserted into pSV00CAT, but not in non-G-CSF-producing tumor cell lines. These results suggest that overproduction of the transactivating factor(s) which binds to the 360 bp of the G-CSF upstream region is responsible for the abnormal expression of G-CSF gene in KHC 287 cell line.

The major hematopoietic growth factors have been produced through recombinant DNA technology and have entered initial clinical trials; results of these trials will be reviewed here. Granulocyte colony-stimulating factor (G-CSF) has been tested in patients with bladder cancer and small-cell carcinoma of the lung. In these studies, G-CSF ameliorated the leukopenia associated with combination chemotherapy, reduced the incidence of mucositis in the bladder cancer patients, and nearly eliminated the occurrence of serious infections in the lung cancer patients. Trials involving another factor, granulocyte macrophage colony-stimulating factor (GM-CSF), have resulted in a marked increase in white blood cell (WBC) counts in patients with myelodysplastic syndromes, and has accelerated the appearance of leukocytes and platelets after autologous bone marrow transplants. GM-CSF can also increase the WBC counts in acquired immunodeficiency syndrome patients treated with zidovudine. Both G-CSF and GM-CSF may produce multilineage effects in certain clinical settings and dose ranges. Finally, interleukin-1 (IL-1) and IL-3, which commit very early stem cells to a myeloid pathway, may be used in combination with G-CSF or GM-CSF to produce a synergistic response to various clinical situations.

An ongoing phase I and pharmacokinetic trial of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) in combination with carboplatin is evaluating the maximum tolerated dose (MTD) of a 3-hour paclitaxel infusion combined with fixed doses of carboplatin in previously treated and untreated patients with a variety of advanced cancers. A patient's previous treatment status determines the fixed carboplatin dose: target area under the concentration-time curves of 4.0 and 4.5 mg.min/mL in previously treated and untreated patients, respectively. Studies 1 and 2 entered previously treated patients to establish the paclitaxel MTD without and with cytokine support: study 1 established 135 mg/m2 paclitaxel as the MTD without such support. In study 2, granulocyte colony-stimulating factor is administered, and the MTD has not yet been reached with paclitaxel doses of 135 mg/m2 to 230 mg/m2 assessed thus far and 250 mg/m2 now being evaluated. Objective responses have been seen in three of five patients with squamous cell carcinoma of the head and neck and in patients with non-small cell lung cancer and metastatic cancer of unknown primary site as well. Myelosuppression has been the dose-limiting toxicity, although significant nausea and vomiting and myalgia have been documented occasionally. Paclitaxel apparently has nonlinear pharmacokinetics with a beta half-life of 6.7 hours (SD +/- 1.3 hours). Future trials of paclitaxel/carboplatin will address the management of squamous cell carcinoma of the head and neck and non-small cell carcinoma of the lung.

In this study we tested whether the pattern of cytokines expressed by human carcinomas could account for a different in vivo recruitment of leukocyte subpopulations as a part of the anti-tumor immune response. Two carcinoma cell lines, SK-OV-3 ovary carcinoma and CALU-3 lung carcinoma, were analyzed by reverse transcriptase-polymerase chain reaction (RT-PCR), immunofluorescence and ELISA for the expression and in vitro production of cytokines with chemotactic, proinflammatory and growth-stimulating activity. Although both cell lines displayed a constitutive expression of granulocyte colony-stimulating factor (G-CSF), granulocyte macrophage-CSF (GM-CSF), M-CSF, interleukin (IL-) 1 alpha and IL-8, only CALU-3 cell line expressed IL-10, RANTES (Regulated upon Activation, Normal T Expressed and Secreted) and monocyte-activating protein (MCP)-1. MCP-1 and IL-8 were detected by immunohistochemistry on sections from tumors xenografted in nude mice. To analyze whether the tumor-released cytokines modulate leukocytes in tumor infiltration, we studied the distribution of human peripheral blood leukocytes injected in the proximity of SK-OV-3 and of CALU-3 tumor xenografts. While SK-OV-3 was unable to recruit human leukocytes and appeared to be barely infiltrated by murine CD45+ cells, CALU-3 appeared to be rapidly and heavily infiltrated by human leukocytes which induced tumor necrosis within 18-24 hr.

This study was aimed at preventing of chemotherapy-induced neutropenia and improving the therapeutic result by reducing the cycle length of cisplatin (25 mg/m2/day, 5-day continuous infusion) and vindesine (3 mg/m2, bolus, days 1 and 8) (PiV) through the use of recombinant human granulocyte colony-stimulating factor (rG-CSF) (2-5 micrograms/kg/day, subcutaneous, days 6-21) for non-small cell lung carcinoma (NSCLC). PiV regimen with rG-CSF was repeated every 21 days. 28 out of 33 previously untreated patients, who completed two or more cycles of PiV regimen on schedule, were evaluable for analysis. The absolute neutrophil count in the third week after chemotherapy was 8187 +/- 5376/ml. It became possible to administer PiV therapy at 3-week intervals. The response rate was 74% (23/31). In conclusion, the combined administration of rG-CSF enabled shortening of administration schedule of PiV therapy and increasing the dose intensity.

Squamous cell lung carcinoma cells obtained from a patient who presented with leukocytosis and hypercalcemia were transplanted into nude mice and a serially transplantable cell line, OKa-N-1, was established. The nude mice transplanted with OKa-N-1 cells displayed leukocytosis and hypercalcemia. Serum levels of granulocyte colony-stimulating factor (G-CSF) and parathyroid hormone-related protein (PTHrP) were both elevated in these mice. In vitro cultivation of this tumor cell line gave rise to a clonal cell line, OKa-C-1. Nude mice transplanted with the OKa-C-1 cell line also showed leukocytosis and hypercalcemia with high serum G-CSF and PTHrP levels. The culture supernatant of OKa-C-1 contained high levels of G-CSF and PTHrP. Immunohistochemical studies showed the expression of PTHrP in OKa-C-1 cells. Reverse transcription polymerase chain reaction revealed the presence of G-CSF and PTHrP mRNA in this cell line. Dexamethasone treatment inhibited the transcription of G-CSF and PTHrP genes. This new human squamous carcinoma cell line, OKa-C-1, would be useful for studying the mechanism of simultaneous production of G-CSF and PTHrP and their control in cancer patients with leukocytosis and hypercalcemia.

Changes in routine hematologic data and in circulating granulocyte-macrophage colony-forming units (CFU-GM) during granulocyte colony-stimulating factor (G-CSF) administration were evaluated in non-small cell lung carcinoma (NSCLC) patients treated with a combination of 5-fluorouracil (5-FU) and cisplatin (DDP) with and without the addition of interferon-alpha (IFN-alpha). The patterns of leukocyte changes following chemotherapy plus G-CSF were similar in both the IFN-alpha-inclusive and the IFN-alpha-devoid courses. However, the twofold increase in CFU-GM observed in patients receiving chemotherapy plus G-CSF was completely absent following the course including IFN-alpha. The activity of G-CSF on the hematologic pattern is seemingly affected by its combination with IFN-alpha treatment. Mechanisms of the possible in vivo interaction among IFNs and hematopoietic growth factors remain to be elucidated.

This study sought to determine the principal toxicities and feasibility of administering paclitaxel as a 3-hour infusion followed by carboplatin without and with granulocyte colony-stimulating factor (G-CSF) in chemotherapy-naive patients with stage IV non-small cell lung carcinoma (NSCLC), and to recommend doses for subsequent clinical trials. Twenty-three patients were treated with paclitaxel at doses ranging from 175 to 225 mg/m2 followed by carboplatin targeting area under the concentration-time curve (AUC) 7 or 9 mg/mL.min every 3 weeks. AUCs were targeted using the Calvert formula with estimated creatinine clearance as a surrogate for the glomerular filtration rate. A high rate of intolerable, mutually exclusive toxicities, consisting primarily of thrombocytopenia, as well as neutropenia, nausea and vomiting, and mucositis, precluded escalation of carboplatin above a targeted AUC of 7 mg/mL.min with paclitaxel 225 mg/m2, which approaches the maximum tolerated dose (MTD) of paclitaxel given as a single agent on a 3-hour schedule. Moderate to severe peripheral neurotoxicity occurred in several patients after multiple courses. Due to the heterogeneous nature of the principal toxicities and the ability to administer clinically-relevant doses of both agents in combination without G-CSF, further dose escalation using G-CSF was not performed. Nine of 23 (39%) total patients and 43% of 21 assessable patients had partial responses (PR). The recommended doses for subsequent clinical trials are paclitaxel 225 mg/m2 as a 3-hour infusion followed by carboplatin at a targeted AUC of 7 mg/mL.min. The ability to administer clinically-relevant single agent doses of paclitaxel and carboplatin in combination, as well as the significant antitumor activity noted in this phase I trial, indicate that further evaluations of this regimen in both advanced and early stage NSCLC are warranted.

Diffuse uptake of 201TI in the axial bone is reported in a patient with large cell carcinoma of the lung who showed leukocytosis and an increased concentration of granulocyte colony-stimulating factor (G-CSF) in plasma. The abnormal bony uptake of 201TI disappeared in association with normalization of the elevated plasma G-CSF level after complete tumor resection. The production of G-CSF was confirmed by immunoperoxidase staining of the tumor tissue.
