Abstract
Photodynamic therapy is useful as organ-preservation salvage therapy for residual recurrence of esophageal squamous cell carcinoma after chemoradiation therapy. However, the high residual recurrence rate of photodynamic therapy poses a problem. We herein report a patient who underwent photodynamic therapy for recurrence of superficial esophageal squamous cell carcinoma after chemoradiation therapy. The patient later exhibited another episode of recurrence of superficial esophageal squamous cell carcinoma, and R0 curative resection was obtained with endoscopic submucosal dissection. This suggests that endoscopic submucosal dissection may be an effective treatment option that can achieve R0 resection even for residual superficial cancer after salvage photodynamic therapy.
