 ESCC(esophageal squamous cell carcinomas)when still localized are typically treated by endoscopy. However, when the tumor invades the muscularis mucosae(MM)and the submucosal layer(SM), the incidence of lymph node metastasis ranges from about 10% to more than 40%. In such cases, esophagectomy with radical lymph node dissection is considered the standard treatment. The efficacy of definitive CRT(chemoradiotherapy)was determined in a clinical trial, and a large randomized prospective trial comparing the outcomes of CRT to those of surgery has been registered. Another trial included combined endoscopic resection and CRT implemented for patients at a high risk for lymph node metastases. In brief, these clinical trials assessed the efficacy of non-surgical treatment. We hope the results of these studies will improve both organ preservation and overall outcomes in treating Stage I ESCC.
