Sustained complete response following combined nedaplatin+ adriamycin+5-fluorouracil therapy in a patient with superficial esophageal cancer -case report-.

A 57-year-old man was admitted to our hospital with dysphagia. Endoscopic examination revealed a wide 0- II c 2/3- circumferential growth with negative iodine staining in the middle-third of the esophagus (25 approximately 32 cm from the incisors). Biopsy examination revealed moderately differentiated squamous cell carcinoma of the esophagus. The depth of invasion was suspected to be not beyond the mucosa (m2), and computed tomography and ultrasonography revealed neither lymph node nor distant metastasis. Esophagectomy or chemoradiation (CRT) was indicated according to the Japanese guidelines for the treatment of esophageal cancer, because endoscopic mucosal resection (EMR) would have been difficult due to the large width of the lesion (2/3 circumferential growth). Chemotherapy was administered with the combined regimen of nedaplatin+adriamycin+5-fluorouracil (NAF) because the patient desired strongly. After completion of two cycles, the cancer lesion disappeared entirely, as determined both clinically and pathologically by endoscopic examination with biopsy, without any major toxicity. At present, 3 years after the chemotherapy, the patient remains free of any evidence of recurrence.
