[Successful Chemotherapy with Mechanical Ventilation Support in a Patient with Esophageal Neuroendocrine Carcinoma-A Case Report].

A 61-year-old female presented with dyspnea. CT scan revealed an esophageal tumor with airway stenosis, and she was referred to our hospital. During endoscopy, oxygen desaturation necessitated emergency endotracheal intubation and mechanical ventilation. Following tracheostomy placement, a diagnosis of NEC cStage ⅣB was established. IP chemotherapy was initiated. The patient was successfully weaned from mechanical ventilation on hospital day 14. Follow-up CT demonstrated tumor shrinkage, and she was discharged home on day 52. After that, IP therapy was continued and the tracheotomy tube was removed on an outpatient visit. Although the patient underwent up to fourth-line treatment, she died of the underlying disease 1 year and 2 months after the starts of treatment.
