摘要
Background: Early gastro-esophageal cancer is staged as m1 to m3 depending on the infiltration of the anatomical layers of the mucosa or, analogously, as sm1 to sm3 depending on the depth of infiltration into the submucosa. The risk of lymph node metastases is low in mucosal carcinoma but increases with the depth of infiltration into the submucosa. Methods: This review is based on pertinent publications retrieved by a selective search in MEDLINE, PubMed, the Cochrane Library, and the International Standard Randomised Controlled Trial Number (ISRCTN) registry. Results: New technologies such as narrow-band imaging have improved the endoscopic diagnosis and staging of early gastro-esophageal cancer. The development of endoscopic submucosal dissection has led to a higher R0 resection rate, a lower risk of recurrence, and an increase in the number of endoscopic resections that are performed with curative intent. In squamous-cell carcinoma of the esophagus, surgical oncological esophagectomy is indicated if the cancer infiltrates into the third mucosal layer (T1a, m3) or deeper. In esophageal adenocarcinoma, the prevalence of lymph node metastases is low if the cancer is restricted to the mucosa and increases only when the submucosa is infiltrated. In the current German S3 guideline, endoscopic resection is recommended for intramucosal adenocarcinoma as long as there are no further histopathological risk factors. Lymph node metastasis in gastric carcinoma begins in the deep mucosal infiltration stage (m3). If certain special conditions ("extended criteria") are met, carcinoma expanding into the first submucosal layer (sm1) can be removed endoscopically. All further stages must be treated with total or subtotal gastrectomy with systematic D2 lymphadenectomy. Conclusion: Borderline cases between endoscopic and surgical resection of early carcinoma of the esophagus or stomach must be managed with an interdisciplinary treatment algorithm. If there is a risk of lymph node metastasis, surgical oncological resection is indicated. Such resections of gastroesophageal cancer in the locally advanced stage should always be part of a multimodal treatment approach.
