Establishment of Image Database for Early Upper Gastrointestinal Cancer, Precancerous Lesions, and Precancerous Conditions
The study is designed to collect magnetically-controlled capsule endoscopy (MCE) images, esophagogastroduodenoscopy (EGD) images, CT images, and histopathology results to establish a database for early upper gastrointestinal cancer, precancerous lesions, and precancerous conditions.
• Male or female participants aged ≥ 18 years
• Patients with early upper gastrointestinal cancer referred for endoscopic submucosal dissection (ESD), or patients with upper gastrointestinal precancerous lesions or precancerous conditions referred for biopsy by esophagogastroduodenoscopy (EGD)
• Participants who are willing and able to participate in this study, complete all required examinations and follow-up visits, and who have provided written informed consent
