Long-term survival following radical surgery after chemotherapy for esophagogastric adenocarcinoma with extensive lymph node metastases: Report of a case

A 46-year-old man was referred to us after he presented to his local physician complaining of difficulty eating. Upper gastrointestinal endoscopy revealed a tumor at the esophagogastric junction (EGJ), and moderately differentiated adenocarcinoma was diagnosed from the biopsy findings. Computed tomography (CT) showed apparent enlargement of the pretracheal lymph nodes, the lymph nodes around the bilateral recurrent laryngeal nerves, and the lower thoracic paraesophageal lymph nodes, confirming metastasis. Since the disease was far advanced esophagogastric cancer with marked lymph node metastases throughout the mediastinum, curative resection would have been unlikely. Thus, he was commenced on systemic chemotherapy with cisplatin (90 mg/body, day 8) + S-1 (120 mg/body/day, given for 3 weeks, followed by a 2-week withdrawal). Even after six cycles of chemotherapy over 8 months, a complete response could not be achieved. Finally, we performed transthoracic subtotal esophagectomy with extensive lymph node dissection reconstructed using a gastric tube through a retrosternal route. The patient remains recurrence-free 7 years later.
