[A Case of Cervical Esophageal Cancer with Lymph Node Recurrence Three Times after Definitive Chemoradiotherapy].

A 56-years old man was diagnosed with cervical esophageal cancer with lymph node metastasis. After definitive chemoradiotherapy as the first-line therapy, complete response(CR)was obtained. One year and 3 months after the therapy, lymph node dissection and postoperative chemotherapy was performed for the lymph node metastases of the left neck and axillary lymph node. After 3 years and 10 months from the first-line therapy, follow-up CT revealed left axillary lymph node swelling and diagnosed with lymph node recurrence. Chemoradiotherapy was performed for the recurrence of the lymph node and CR was achieved for the lymph node. However, left axillary lymph node swelling were detected again 6 years after the first-line therapy. After 6 months of chemotherapy with S-1, CR was achieved for the lymph node again. He is now alive without recurrence for 10 years after the first-line therapy.
