放射線単独療法で完全に治癒した表在性食道癌：症例報告

Surgery is the definitive treatment for superficial esophageal cancer. However, the risks and complications associated with surgery often lead to further complications. Endoscopic resection is an effective treatment option for superficial esophageal cancer. However, if the cancer invades more than three-quarters of the esophageal lumen, the risk of complications is high from both the procedure and potentially troublesome post-endoscopic esophageal stricture. To mitigate these issues, neoadjuvant radiotherapy or chemoradiotherapy may be administered before endoscopic resection to reduce the size of esophageal cancer. This report presents a case of complete remission of superficial esophagus cancer achieved with radiotherapy alone.
