Core Tip

Core Tip: The current case highlights the successful application of endoscopic submucosal dissection (ESD) as a salvage therapy for esophageal squamous cell carcinoma after chemoradiotherapy for pharyngeal cancer. This case underscores the potential of ESD to achieve curative resection in patients with complex malignancies and emphasizes the importance of further research to validate its efficacy and safety in similar contexts.
