1/43. paraneoplastic syndromes of leukocytosis, thrombocytosis, and hypercalcemia associated with squamous cell carcinoma.paraneoplastic syndromes including leukocytosis, thrombocytosis and hypercalcemia are occasionally seen in patients suffering from progressive malignant disorders. Recent studies have revealed the production of several humoral factors by tumor cells and normal splenic cells of tumor-bearing patients to be the major cause of these reactions. granulocyte-macrophage colony-stimulating factor (GM-CSF), granulocyte-colony stimulating factor (G-CSF), parathyroid hormone-related peptide, interleukin (IL)-1, IL-6, and tumor necrosis factor (TNF) have been implicated. We describe a 58-year-old Japanese man with squamous cell carcinoma (SCC) on the left sole, which developed in a deep linear scar after a train crash. He developed pulmonary and lymph node metastases, then leukocytosis (57,110/mm3 with 95% neutrophilia), thrombocytosis (86.3 x 10(4)/mm3), and hypercalcemia (7.0 mEq/1), and finally cachexia, followed by death. serum G-CSF, IL-1 alpha, IL-1 beta, and TNF-beta were determined; revealing G-CSF and IL-1 beta levels were above the upper limits of their normal ranges at 39.2 pg/ml and 4.63 pg/ml, respectively. It is probable that these humoral factors were partially responsible for the paraneoplastic syndromes induced by the cutaneous SCC with metastasis in the present case.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
2/43. An immunohistochemical study on a case of granulocyte-colony stimulating factor-producing gall-bladder carcinoma.Primary gall-bladder carcinoma producing granulocyte-colony stimulating factor (GCSF) is extremely rare. Only four cases, histologically investigated, have been reported to date in the English literature. We report a case of a 48-year-old female with primary gall-bladder carcinoma, associating with leukocytosis (15 700/mm3) and a high level of serum GCSF (54.0 pg/mL). The tumor was, histologically, a poorly differentiated adenocarcinoma with marked interspersed neutrophils invading into the primary tumor itself and the right lobe of the liver. Tumor cells distinctly showed positive immunoreaction in the cytoplasm with anti-GCSF antibody, and in the nucleus for anti-p53 antibody. After surgery, the leukocytosis and serum level of GCSF began to decrease. These findings confirmed the present case of GCSF-producing gall-bladder carcinoma, exhibiting leukocytosis. A total of five cases, including our case, reported as a GCSF-producing gall-bladder carcinoma were clinicopathologically reviewed.- - - - - - - - - - ranking = 1.8keywords = carcinoma (Clic here for more details about this article) |
3/43. Neutrophilia associated with anaplastic carcinoma of the thyroid: production of macrophage colony-stimulating factor (M-CSF) and interleukin-6.Cancers associated with marked neutrophilia are relatively rare. We report here two cases of anaplastic thyroid carcinoma associated with neutrophilia. We measured the concentrations of granulocyte colony-stimulating factor (G-CSF), macrophage CSF (M-CSF), granulocyte-macrophage CSF (GM-CSF), interleukin-1alpha (IL-1alpha), IL-1beta, IL-6, and tumor necrosis factor-alpha (TNF-alpha) in sera, pleural effusion, cyst fluid of the thyroid carcinoma region, or culture supernatants of carcinoma cells. Maximum levels of elevated white blood cell counts reached 106.1 x 10(9)/L (neutrophils 103.0 x 10(9)/L) in case 1 and 62.3 x 10(9)/L (neutrophils 57.9 x 10(9)/L) in case 2. Acute-phase reactants were elevated to various degrees, and hypercalcemia was found in both cases. IL-6, G-CSF, and M-CSF seemed to play the principal roles in neutrophilia in case 1, and the elevated levels of IL-6 and M-CSF seemed to mainly contribute to neutrophilia in case 2. Immunohistochemical staining revealed that carcinoma cells themselves produce IL-6 regardless of the types of carcinoma cells. To our knowledge, this is the first report describing the contribution of M-CSF to neutrophilia in patients with thyroid carcinoma.- - - - - - - - - - ranking = 2keywords = carcinoma (Clic here for more details about this article) |
4/43. Rapidly relapsing squamous cell carcinoma of the renal pelvis associated with paraneoplastic syndromes of leukocytosis, thrombocytosis and hypercalcemia.A case history is reported here in which leukocytosis, thrombocytosis and hypercalcemia associated with rapidly relapsing squamous cell carcinoma (SCC) of the renal pelvis were observed. In a 58-year-old man, SCC of the renal pelvis was documented during nephrolithotomy, and right nephrectomy was performed. Local relapse of the tumor occurred rapidly in 2 months' time and hypercalcemia, leukocytosis and thrombocytosis worsened in accordance with tumor volume. Cranial computerized tomography (CT), thorax CT and bone scintigraphy were negative for metastasis. The serum parathyroid hormone level was 28 pg/ml (normal 9- 55 pg/ml). To disclose leukocytosis and thrombocytosis, peripheral smear and bone marrow aspiration were performed and no pathologic finding regarding any hematologic disorder was found; the samples were also BCR-ABL negative and philadelphia chromosome negative. Production of several factors by tumor cells may be responsible for this paraneoplastic syndrome. The association of SCC of the renal pelvis with this triple paraneoplastic syndrome is an extremely rare occurrence.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
5/43. Overexpression of CXC chemokines by an adrenocortical carcinoma: a novel clinical syndrome.A patient with adrenocortical carcinoma presented with fever, leukocytosis, and increased acute phase reactants. The tumor was infiltrated with neutrophils. Immunohistochemical staining of the tumor showed positive signal for epithelial neutrophil-activating protein-78, an angiogenic and chemotactic CXC chemokine. Conditioned medium from tumor-derived cells (RL-251) showed high concentration of IL-8, epithelial neutrophil-activating protein-78, Gro alpha, and Gro gamma, angiogenic CXC chemokines with a potential role in tumorigenesis. An adrenal cancer/severe combined immunodeficiency mouse chimera was developed. mice grew tumors rapidly, and circulating levels of IL-8 and epithelial neutrophil-activating protein-78 were detected. In contrast, animals transplanted with NCI-H295 cells, a nonchemokine-secreting cell line, grew tumors more slowly and did not have detectable chemokine levels. Similar to the patient, mice with RL-251 tumors developed marked leukocytosis and neutrophilia, and their tumors were infiltrated with neutrophils. mice were passively immunized with epithelial neutrophil-activating protein-78 antisera. A marked decrease in tumor growth was observed. Potential for chemokine production by other adrenocortical tumors was investigated by RT-PCR in archival material. Six of seven adrenal carcinomas and one of three adenomas had cDNA for IL-8; six of seven carcinomas and the three adenomas had cDNA for epithelial neutrophil-activating protein-78. We concluded that the clinical presentation of this case resulted from increased tumor production of chemotactic chemokines. Through their angiogenic and chemotactic properties these chemokines may play an important role in adrenal tumorigenesis.- - - - - - - - - - ranking = 1.4keywords = carcinoma (Clic here for more details about this article) |
6/43. Primary adenosquamous carcinoma of the liver which produces granulocyte-colony-stimulating factor and parathyroid hormone related protein: association with leukocytosis and hypercalcemia.A 55-year-old man was admitted to our hospital with fever and vomiting. Abdominal computed tomography (CT) revealed multiple low density masses in the liver. A diagnosis of primary adenosquamous carcinoma of the liver was confirmed by histological examination of a necropsy specimen. The present case showed leukocytosis and hypercalcemia with high levels of serum granulocyte-colony-stimulating factor (G-CSF) and parathyroid hormone related protein (PTHrP). Recent studies have shown that G-CSF and PTHrP are responsible for the paraneoplastic syndromes with leukocytosis and hypercalcemia. The tumor cells demonstrated positive cytoplasmic immunohistochemistry staining with anti-G-CSF and anti-PTHrP antibodies. This result suggested that the tumor produced G-CSF and PTHrP.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
7/43. PTHrP-producing tumor: squamous cell carcinoma of the liver accompanied by humoral hypercalcemia of malignancy, increased IL-6 and leukocytosis.A 77-year-old man was admitted to our hospital showing symptoms of general fatigue and appetite loss. He had leukocytosis, thrombocytosis and hypercalcemia with elevated serum levels of parathyroid hormone related peptide (PTHrP) and interleukin-6 (IL-6). An increase in tumor markers SCC and CYFURA21-1 was observed. The liver contained a huge tumor, which was proved to be PTHrP producing squamous cell carcinoma by immuno-histochemical analysis. Since the tumor did not express IL-6, it was assumed to be induced by PTHrP in osteoblasts. This is the first report of PTHrP producing squamous cell carcinoma of the liver.- - - - - - - - - - ranking = 1.2keywords = carcinoma (Clic here for more details about this article) |
8/43. Establishment of large cell lung cancer cell lines secreting hematopoietic factors inducing leukocytosis and thrombocytosis.We have established cell lines from a large cell carcinoma of the lung accompanied by marked granulocytosis and thrombocytosis, and have analyzed the factors with colony stimulating factor (CSF) activity produced by them. Analysis of the CSF activity present in the culture medium of the established cell lines demonstrated growth-stimulating activity on CMK cells, a human megakaryoblastic cell line and mouse bone marrow cells. A neutralization test with antibodies against G-, M- and GM-CSF indicated the stimulation for the proliferation of CMK and mouse bone marrow cells to be mediated partially by the CSFs. Furthermore, the measurement of GM-CSF and interleukin(IL)6 by enzyme-linked immunosorbent assay (ELISA) and northern blotting analysis indicated productions of G-, GM- and M-CSF and of IL6 from the cell lines but failed to exhibit IL3 gene expression. It is suggested that the cell lines could be of use in the study of CSFs and, also, that lymphokines act on leukocyte and platelet progenitor cells.- - - - - - - - - - ranking = 0.2keywords = carcinoma (Clic here for more details about this article) |
9/43. Anaplastic thyroid carcinoma with prominent cardiac metastasis, accompanied by a marked leukocytosis with a neutrophilia and high GM-CSF level in serum.Cardiac metastasis of thyroid carcinoma is extremely rare. We treated a case of anaplastic thyroid carcinoma with prominent cardiac metastasis. The 61-year-old male was admitted because of high fever. Investigations revealed a cardiac mass and anaplastic thyroid carcinoma. Resection of the cardiac mass revealed that it was metastasis from the thyroid carcinoma. After 4 months, he died in spite of intensive therapy. Marked leukocytosis was observed during the clinical course, and a concomitant increase of granulocyte macrophage-colony stimulating factor (GM-CSF) level was demonstrated in the sera. It was suggested that the high GM-CSF level in serum contributed to leukocytosis.- - - - - - - - - - ranking = 1.6keywords = carcinoma (Clic here for more details about this article) |
10/43. Squamous cell carcinoma of the lung producing granulocyte colony-stimulating factor and resembling a malignant pleural mesothelioma.A 65-year-old was admitted to our hospital and was diagnosed as having squamous cell carcinoma originating in the right upper bronchus. He underwent both chemotherapy and radiation therapy, but these therapies were ineffective and thereafter the developed radiation pneumonitis and carcinomatous pleuritis. Finally, he died of bacterial pneumonia in the opposite normal lung of four months duration. From one month before his death, laboratory data indicated marked leukocytosis, and his granulocyte colony-stimulating factor (G-CSF) serum level was high. At autopsy, squamous cell carcinoma was found in the right hilus region of the lung, with a spreading form resembling a malignant pleural mesothelioma mainly occupying the pleural cavity. Based on positive staining method with specific monoclonal antibodies against G-CSF, it was considered that the leukocytosis was caused by G-CSF producing tumor.- - - - - - - - - - ranking = 1.4keywords = carcinoma (Clic here for more details about this article) |
