Usefulness of endoscopic salvage treatment in a patient with local failure esophageal cancer after CRT

Chemoradiotherapy (CRT) is widely used as non-surgical treatment for esophageal cancer in recent years. CRT is very useful, but it allows about 40% relapse. Salvage surgery after CRT, long-term survival can be expected, but perioperative mortality is high. In contrast, EMR for local failure after definitive CRT has been reported showing a 5-year survival rate of 49. 1%. If it can safely control of local failure, then we thought it's useful for long-term survival. If the depth of invasion was to the submucosal layer of the local failure lesion, we performed an endoscopic resection. If vertical margins are positive pathologically, we have added a photodynamic therapy. In cases of difficult endoscopic resection, PDT alone was performed. We experienced a case of recurrent esophageal cancer after CRT was useful for local treatment with PDT and EMR.
