Case report shows endoscopic resection achieved negative margins in gastric cancer after chemoradiation, suggesting it may be a viable option for non-surgical candidates.
Salvage endoscopic resection of residual esophageal neoplasia for patients that prefer to avoid surgery or are poor surgical candidates has been reported. We report a case of gastric signet ring cell carcinoma with residual disease after definitive chemoradiotherapy, that was treated with nonexposed endoscopic full thickness resection. This endoscopic resection achieved negative margins, with postresection surveillance endoscopy and imaging showing no evidence of disease. This case highlights the potential use of salvage endoscopic resection as a therapy for residual gastric cancer after chemoradiation in patients where surgery is not an option.
