[A case of stage IV (A3) cervical and upper thoracic esophageal adenocarcinoma successfully treated with concurrent chemoradiotherapy].

We report a case of cervical and upper thoracic esophageal adenocarcinoma with tracheal stenosis and bilateral recurrent nerve palsy. A 64-year-old man with unresectable esophageal cancer (A3, N1, M0) was treated with concurrent chemoradiotherapy. A dose of 67.4 Gy was irradiated to the cervical and upper thoracic area where the primary tumor and lymph node metastases were located, and six courses of 5-FU (250 mg/24 h/day 1-5) and CDDP (5 mg/1 h, just before radiation/day 1-5) were delivered concurrently. The esophageal tumor showed a complete response (CR), and the paratracheal lymph node metastases showed partial responses (PR). The reason these therapies were more effective against the tumor than the lymph node metastases is uncertain. The patient is no longer required to stay in the hospital, and his QOL has been improving. His condition has been maintained for 4 months, so this type of concurrent chemoradiotherapy may be recommended for cervical and upper thoracic esophageal adenocarcinoma.
