[A Case of Small Cell Carcinoma of Esophagus in Which Long-Term Survival Was Achieved with Multimodal Treatment].
2020
A 79-year-old man presented to our hospital with 1-month history of discomfort on swallowing and pain in the thoracodorsal region. Image investigation revealed a tumor lesion affecting the area from the lower esophagus to the gastric antrum, and small cell carcinoma of esophagus was diagnosed based on biopsy. He was treated with resection of the lower esophagus and the upper part of the stomach and a postoperative chemoradiotherapy. The patient follow-upwas without recurrence until a malignant lymphoma developed 4 years and 5 months after the surgery. Chemotherapy was provided for the malignant lymphoma, however, the patient died 6 years and 4 months after the surgery for small cell carcinoma of esophagus. Small cell endocrine carcinoma of the esophagus is a relatively rare disease and its prognosis is poor. In our patient, long-term survival was achieved with multimodal treatment, however malignant lymphoma developed during the follow-upp eriod. This is the second case of metachronous cancer after the treatment for small cell carcinoma of the esophagus in Japan, and it is considered to be extremely rare.
