We report a case of advanced esophageal and gastric cancer that was successfully treated via multimodal therapy. A 65- year-old man with hoarseness was referred to our hospital. He was diagnosed with clinical T4aN2M0, Stage IV esophageal squamous cell carcinoma and clinical T3N1M0, Stage II B gastric adenocarcinoma. He was treated with 3 courses of chemotherapy, administered over 4weeks, with S-1(80mg/m / / 2: day 1-14), cisplatin(60mg/m2: day 1), and docetaxel(40mg/m2: day 1). Computed tomography(CT)revealed shrinkage of the primary esophageal tumor, gastric tumor, and lymph node metastases. Next, we selected definitive radiation chemotherapy(CRT), because lymph node metastases remained around the bilateral recurrent laryngeal nerves. After CRT with a total 60 Gy plus administration of 5-fluorouracil and cisplatin, CT showed that the primary esophageal tumor and lymph node metastases had disappeared. Then, distal gastrectomy was performed for the remaining gastric cancer, as part of the multimodal therapy. After gastrectomy, no systemic chemotherapy was performed. At a follow-up examination 5 years and 6 months after the start of chemotherapy, the patient is alive without recurrence.
