The expression of granulocyte colony-stimulating factor (G-CSF) mRNA was studied in human non-hematopoietic tumors, including 18 cases of lung cancers 10 cases of stomach cancers, three cases of glioblastomas, and one case each of breast phyllode sarcoma, thyroid cancer, and hepatocellular carcinoma. Northern blot analysis detected G-CSF mRNA in two of the lung cancer cases, in one of the glioblastoma cases, and in both the breast phyllode sarcoma and hepatocellular carcinoma cases. Since G-CSF receptors were not detected on the tumor cells by 125I-G-CSF binding assay, G-CSF autocrine loop are probably not involved in the growth of these G-CSF-producing tumors. Interestingly, granulocyte-macrophage colony-stimulating factor (GM-CSF) mRNA was concomitantly expressed in most of these G-CSF-producing tumors. No major gene deletions or rearrangements of G-CSF and GM-CSF genes were demonstrated by Southern blot analysis in the tumors expressing G-CSF and GM-CSF mRNAs except for one of the glioblastomas (G3) in which one chromosome 17 allele was deleted. Although the mechanism of the concomitant expression of G-CSF and GM-CSF mRNA is unknown, relatively high frequency of this phenomenon suggests the presence of common transcriptional factors acting on regulatory regions of G-CSF and GM-CSF genomes.

Cancers producing colony-stimulating factors and associated with marked leukocytosis are relatively rare. We report here a case of a thyroid cancer producing both granulocyte colony-stimulating factor (G-CSF) and granulocyte-macrophage colony-stimulating factor (GM-CSF). A 72-year-old woman had a thyroid carcinoma with significant neutrophilia and eosinophilia without any evidence of infection. The serum concentrations of both G-CSF and GM-CSF were elevated significantly in this patient, which might have induced the leukocytosis. Furthermore, the G-CSF concentrations in thyroid tumor tissue and metastatic lesions in the lung and skin examined at autopsy also were extremely high.

A new thyroid cancer cell line, KTC-2, was established from the malignant pleural effusion of a patient with recurrent thyroid cancer associated with anaplastic transformation from thyroid papillary cancer. Karyotype analysis showed a mode of 109 chromosomes. Subcutaneous cell injections produced small regressing tumors in athymic or severe combined immunodeficiency disorders (SCID) mice. Histologic examination showed anaplastic tumor cells surrounded by prominent mononuclear cells. An expression of thyroglobulin, thyroid transcription factor-1, and PAX-8 but not thyroid peroxidase and thyrotropin (TSH) receptor was detected. Biochemical analysis revealed secretion of interleukin (IL)-6, parathyroid hormone-related protein (PTHrP), and granulocyte-macrophage colony-stimulating factor. All the cytokines are known to induce paraneoplastic syndromes in patients with anaplastic thyroid cancer. Our previous studies revealed that medroxyprogesterone acetate (MPA) reduces secretion of IL-6 and PTHrP from human breast cancer cells. To investigate the regulatory mechanisms of secretion of these cytokines, MPA was administered to the KTC-2 cells. MPA dose-dependently decreased the secretion and mRNA expression of IL-6 and PTHrP. Expression of androgen receptor and glucocorticoid receptor (GR) but not progesterone receptor was detected. Dexamethasone but not dihydrotestosterone and progesterone decreased IL-6 and PTHrP secretion. These findings suggest that MPA decreases IL-6 and PTHrP secretion as a glucocorticoid mediated by GR in the KTC-2 cells. This KTC-2 cell line may be a suitable model for developing new strategies against paraneoplastic syndromes caused by anaplastic thyroid cancer.

Granulocyte colony-stimulating factor (G-CSF) and granulocyte-macrophage colony-stimulating factor (GM-CSF) sensitise nerves to mechanical stimuli experimentally and may induce bone and muscle pain when used as supportive drugs. G-CSF and GM-CSF produced endogenously by tumour cells can cause paraneoplastic leucocytosis. Whether paraneoplastic leucocytosis is associated with changes in pain sensitivity is not yet clear. We report on a patient with advanced-stage thyroid cancer who developed extreme leucocytosis within a period of 4 weeks (103 000 white blood cells/mm(3)), composed mostly of neutrophils and eosinophils. Parallel to this leukemoid reaction, allodynia and hyperalgesia developed in the absence of tissue inflammation. The course of disease of an elderly male with advanced stage metastatic thyroid cancer with new onset neuropathic pain followed by the development of extreme leucocytosis in a leukemoid reaction suggests paraneoplastic release of myeloid CSFs. The coincidence of pain sensitisation and extreme leucocytosis suggests a causal contribution of G-CSF and GM-CSF.

Anaplastic thyroid carcinoma is a rare disease, and cases associated with eosinophilia are even rarer. We herein report a case of anaplastic thyroid carcinoma accompanied by remarkable and uncontrollable eosinophilia. A 71-year-old man was diagnosed with end-stage anaplastic thyroid carcinoma. Throughout the aggressive clinical course of the cancer, eosinophilia dramatically progressed and became extremely refractory to steroid treatment. We measured the serum levels of hematopoietic cytokines potentially involved in eosinophilia, including granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin (IL)-3 and IL-5. Although the GM-CSF level was moderately elevated, both the IL-3 and IL-5 levels were within the normal ranges. In this case, the patient's eosinophilia may have been related to his severe dyspnea and was likely responsible for the allergic reaction to the anticancer drug. Therefore, it is essential to elucidate the etiology of eosinophilia in patients with thyroid cancer in order to improve the treatment for patients with anaplastic thyroid carcinoma.
