[A Case of Advanced Esophageal Cancer Successfully Treated with Neoadjuvant Chemotherapy Containing 5-FU, Docetaxel. and Nedaplatin Combination Therapy].

A 71-year-old man with a history of hypertension, diabetes mellitus, and cerebral infarction was admitted to our hospital with dysphagia. Gastroduodenoscopy, thoracoabdominal CT, and PET-CT findings showed type 2 advanced esophageal cancer( squamous cell carcinoma)with upper mediastinal and cervical lymph node(LN)metastasis: cT3N2M1(LYM #104L), cStage Ⅳ. Two courses of neoadjuvant UDONchemotherapy containing 5-FU(640mg/m / 2, days 1-5), docetaxel(28mg/m2, days 1 and 15), and nedaplatin(72mg/m2, day 1)were administered every 4 weeks. UDONtherapy caused grade(Gr)3 febrile neutropenia, Gr 2 diarrhea, and Gr 1 thrombopenia; the tumor and LNs partially responded to the therapy. After 2 courses of UDONtherapy, esophagectomy with right thoracotomy, 3-field LNdissection, and reconstruction of the gastric tube were performed. The postoperative course was almost uneventful besides recurrent nerve palsy, aspiration, pneumonia, and delirium, and the patient was discharged 60 days after surgery. The pathological diagnosis was ypT0N0M0, ypStage 0, and the histological response of the primary tumor and LNs were evaluated as Gr 3. Neoadjuvant UDON therapy is feasible for elderly patients with advanced esophageal cancer and renal failure or comorbidities, for whom CDDP could not be administered. We are planning a clinical trial to assess the effectiveness of neoadjuvant UDONtherapy.
