[Granulocyte-colony stimulating factor producing tumor with high serum interleukin-6].
ABSTRACT A 53-year-old man admitted to our hospital because of fever and chest abnormal shadow. Chest X-ray and computed tomography (CT) scan revealed large tumor on right upper lobe. Serum interleukin (IL)-6 and granulocyte-colony stimulating factor (G-CSF) were high. Right upper lobectomy and chest wall resection was performed. Histological diagnosis was large cell carcinoma. Immunohistological examination of lung tumor cells showed positive staining for G-CSF in only 1% of them. We diagnosed that tumor was G-CSF producing tumor and we thought that tumor produced IL-6.

ABSTRACT: A 77-year-old woman visited our institution complaining of general fatigue. Chest radiography revealed masses in the upper and middle lung fields. Pathological findings for an endoscopic biopsy specimen revealed squamous cell carcinoma. High-grade fever developed and blood analyses revealed sustained elevated white blood cell count and C-reactive protein levels. Cytokine production by tumor cells was suspected; both serum granulocyte colony-stimulating factor (117 pg/mL; normal: <57.5 pg/mL) and interleukin-6 (83.5 pg/mL; normal: <2.41 pg/mL) levels were high. Immunohistochemical examination of biopsy specimens showed positive staining with antigranulocyte colony-stimulating factor and anti-interleukin-6 monoclonal antibodies. Diagnosis of a tumor that produced granulocyte colony-stimulating factor and interleukin-6 was established. The patient was administered best supportive therapy since she was not eligible for surgical treatment because of her poor respiratory function. She died from interstitial pneumonia exacerbation two months after this diagnosis. We present a female with squamous cell carcinoma of the lung that produced granulocyte colony-stimulating factor and interleukin-6.Case Reports in Medicine 01/2013; 2013:325127.
