Abstract:
The patient was a 42-year-old man who presented with dysphagia.Upper gastrointestinal endoscopy revealed a protruding lesion in the lower thoracic esophagus.Pathological analysis of the lesion showed squamous cell carcinoma.Laboratory data showed leukocytosis(21,200/mL)despite no evidence of infection, and the serum levels of granulocyte colony-stimu- lating factor(G-CSF)were elevated to 283 pg/mL.We diagnosed him with esophageal squamous cell carcinoma(Lt, type 1, cT4N4M0, cStage IV a).After administering 2 courses of docetaxel plus cisplatin plus S-1(DCS)as neoadjuvant chemotherapy, the patient underwent surgery.The pathological diagnosis was pType 2, T2, N4, M0, pStage IV a. G-CSF immunostaining was positive in tumor cells.After the surgery, the number of leukocytes and serum G-CSF levels decreased to within normal limits.Adjuvant chemotherapy was administered.
