RESUMEN
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.

The first patient was a man in his eighties who visited our department because of anemia. Gastrofiberscopy revealed a bleeding submucosal tumor, approximately 50mm in diameter, in the cardia ofthe stomach. Considering that he underwent coronary-artery bypass surgery and received 3 oral antithrombotic medicines, his bleeding tendency was so high that we decided to choose partial gastrectomy. A postoperative histopathological examination revealed that the tumor was a small cell endocrine carcinoma. The second patient was a woman in her seventies. She had consulted her personal physician because of gastric ulcers; periodic gastrofiberscopy revealed a type 3 gastric cancer, approximately 40mm in diameter, on the posterior wall ofthe middle section ofher stomach. It was histologically diagnosed as a poorly differentiated neuroendocrine carcinoma. On a preoperative blood examination, the levels ofhormones such as glucagon, serotonin, and gastrin were within their respective normal limits. Total gastrectomy was performed, and she received oral S-1 for adjuvant chemotherapy since her discharge from the hospital.
