• Conditions: Early Esophageal Cancer or Precancerous Lesions Treated With Endoscopic Resection

• Registration Number: NCT03377972
• Lead Sponsor: Shanghai Zhongshan Hospital

Brief Summary

Endoscopic Submucosal Dissection (ESD) is currently the main method of treatment of early esophageal cancer and precancerous lesions. Therefore, the investigators are looking forward to conduct a cohort study on early esophageal cancer patients undergoing endoscopic treatment collected from Zhongshan Hospital, Fudan University, comparing the WHO standard with Japanese standard of endoscopic therapy diagnosis.
