Image collection for early upper gastrointestinal cancer and precancerous conditions

Establishment of Image Database for Early Upper Gastrointestinal Cancer, Precancerous Lesions, and Precancerous Conditions

Observational Changhai Hospital · NCT07462247

This project will collect capsule endoscopy, endoscopy, CT, and biopsy images from adults with early upper gastrointestinal cancer or precancerous conditions to build an image database to support better image-based diagnosis.

What this trial studies

This observational effort will gather magnetically-controlled capsule endoscopy (MCE) images, esophagogastroduodenoscopy (EGD) images, CT scans, and corresponding histopathology results from patients undergoing ESD or biopsy for early upper gastrointestinal cancer and precancerous lesions/conditions. Collected images and pathology will be linked and curated to form a standardized database suitable for training and validating image-based deep learning models. Participants must be adults able to consent and tolerate the procedures; standard exclusions apply for capsule retention risk, implanted electromedical devices, pregnancy, and relevant allergies. The work is being conducted at Changhai Hospital and aims to address the current scarcity of MCE image datasets.

Who should consider this trial

Good fit: Adults (age ≥18) referred for endoscopic submucosal dissection for early upper GI cancer or for EGD biopsy of upper GI precancerous lesions/conditions who can undergo the imaging procedures and provide informed consent are ideal candidates.

Not a fit: Patients with swallowing difficulties, suspected intestinal stenosis, implanted electromagnetic devices, pregnancy, or those unwilling/unable to undergo the imaging procedures are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the database could enable more accurate and earlier noninvasive diagnosis by supporting AI tools trained on diverse, well-annotated images.

How similar studies have performed: AI studies using EGD and CT images have shown promising diagnostic results, but MCE image datasets are sparse and combining MCE with linked pathology in a database is relatively novel.

4. Patients with dysphagia
5. Pregnancy
6. Allergy to polymeric materials, latex, simethicone, or pronase
7. Patients plan to undergo magnetic resonance imaging examination before excretion of the capsule
8. Patients with any condition that precludes compliance with the study
