Lymph node metastasis after endoscopic submucosal dissection of a superficial esophageal adenocarcinoma arising from the ectopic gastric mucosa of the cervical esophagus: A case report

Multidisciplinary treatment of advanced cervical esophageal adenocarcinoma derived from a gastric inlet patch: A case report

A gastric inlet patch (GIP) is an ectopic gastric mucosal lesion usually arising at the cervical esophagus that may rarely cause esophageal adenocarcinoma (EAC). To the best of our knowledge, this is the first case of a GIP-derived EAC that was successfully treated using a multidisciplinary treatment approach. A 64-year-old man was referred to the Department of Gastrointestinal Surgery, Kanazawa University Hospital (Kanazawa, Japan) for surgical treatment of refractory recurrent cervical EAC derived from GIP who had previously been treated with induction chemotherapy, definitive chemoradiotherapy and photodynamic therapy (PDT). Esophagogastroduodenoscopy revealed a stenotic tumor at the GIP site in the cervical esophagus and submucosal tumors with suspected multiple intramural metastases in the anal side of the thoracic esophagus. The patient underwent robot-assisted thoracoscopic esophagectomy with laryngopharyngectomy and cervical lymphadenectomy as radical salvage surgery 4 months after the last PDT procedure. After postoperative adjuvant chemotherapy using oral administration of tegafur/gimeracil/oteracil (oral 5-fluorouracil prodrug) for 1 year; at present, the patient is alive without recurrence 3 years after the operation.
