Brief Summary: With the development of endoscopy more and more patients with superficial esophageal squamous cell carcinoma ESCC receive endoscopic resection rather than traditional surgery However there is still no complete consensus on the risk factors for lymph node metastasis LNM and recurrence of ESCC after endoscopic resection The existing curative resection criteria are strict to a certain extent and a considerable number of patients are overtreated according to the current standard of additional treatment Thus we aim to conduct a multi-center retrospective and prospective study to construct a large cohort of ESCC based on the previously established multi-center collaborative research network and clinical big data analyze the risk factors of LNM and recurrence in patients with early esophageal squamous cell carcinoma after ESD establish an accurate and simple risk prediction model and evaluate the discrimination efficiency of this model
