Salvage Endoscopic Full-Thickness Resection of Colorectal Carcinoma after Radiotherapy in a Patient Not Eligible for Surgery

Abstract

For early, superficial colorectal carcinoma, endoscopic resection is an accepted curative treatment with an excellent long-term prognosis. Our report is the first report describing endoscopic full-thickness resection (eFTR) of residual recto-sigmoid carcinoma after radiotherapy. Our patient with cT2N0M0 recto-sigmoid carcinoma had been treated with radiotherapy because severe comorbidity precluded surgical resection. When the residual tumor was observed endoscopically, complete remission was achieved by endoscopic full thickness resection. There were no endoscopic or radiological signs of recurrent malignancy after the two-years follow-up period. In selected cases, eFTR after radiotherapy could be a curative treatment option.
