Abstract
This report presents a case of extensive oral cancer suspected to be a granulocyte-colony-stimulating-factor (G-CSF)-producing tumor in a 63-year-old man who complained of dyspnea, dysphagia, and dysmasesis. Laboratory findings on admission showed marked leukocytosis (35, 900/μl) and thrombocytosis (527, 000/μl).Pathological examination of a biopsy specimen revealed an undifferentiated squamous cell carcinoma. Chemotherapy with PEP, CDDP, MTX, UFT, and concurrent irradiation resulted in shrinkage of the tumor and a decrease in the leukocyte and platelet counts. Soon after 10 Gy of radiation had been administered, the serum G-CSF concentration reached the abnormally high level of 329pg/ml and was still 132pg/ml at death about a month later. Over the entire course of treatment, the leukocyte count changed with changes in tumor size. Both findings suggest that the tumor cells produced G-CSF.
