Who Can Participate
Eligibility Criteria
You may qualify if you...
- Age 18 years or older
- Patients diagnosed with an upper gastrointestinal subepithelial lesion (SEL) by white-light endoscopy
- Completed an endoscopic ultrasound (EUS) examination
- Histopathological diagnosis of GIST confirmed by surgical or endoscopic resection, or other SELs confirmed by surgical resection, EUS-guided sampling, or biopsy
- EUS images meet quality control standards including use of specified equipment, clear lesion and surrounding tissue images, no artificial annotations, and resolution of at least 448 x 448 pixels
- White-light endoscopy images clearly showing lesion location, mucosal features, and margins with at least one close-up and one distant view
- Complete clinical data and histopathological reports available
You will not qualify if you...
- Age under 18 years
- Absolute contraindications to EUS examination
- History of gastric surgery
- Pregnancy
- Severe comorbidities
- Known allergy to anesthetic agents
- Premature termination of EUS examination due to esophageal stricture, obstruction, large lesions, rapid heart or respiratory rate changes, patient intolerance, or excessive residual food
- EUS image quality not meeting required standards
- Pathological specimens insufficient for diagnosis or incomplete immunohistochemical staining (missing CD117/CD34/DOG-1 for GIST group)
- Lesion is a metastatic tumor from another site
