Popis: We present herein a case of a patient who was clinically diagnosed as having a granulocyte-colony stimulating factor (G-CSF)-producing tumor on the basis of the close correlation of the hematological parameters with the tumor status and his high serum G-CSF level. A 76-year-old male patient underwent transthoracic radical esophagectomy for advanced carcinoma of the lower esophagus. His leukocyte count and serum G-CSF level were markedly high at 24 260/μl and 134 pg/ml, respectively, before the operation. By immunohistochemical staining of the resected tumor, focal but obvious expression of G-CSF was demonstrated in the cytoplasm of cancer cells, and neutrophilic infiltration was histologically observed in adjacent struma of the tumor invasion front. After surgery, the leukocyte count decreased to a nearly normal level but increased again when the disease recurred in the pleura and lymph nodes 5 months later. Although palliative chemoradiotherapy decreased the leukocyte count to a normal level transiently, leukocyte count again markedly increased when metastatic disease occurred. The leukocyte count reached 78 060/μl the day before the patient died.
