Summary
Linked Color Imaging-Computer-Aided Detection (LCI-CAD EYE) shows high sensitivity for detecting gastric neoplasms during endoscopy. This system aids endoscopists in identifying cancerous lesions, improving diagnostic accuracy in real-world clinical settings.
Area of Science:
- Gastroenterology
- Medical Imaging
- Oncology
Background:
- Computer-aided detection (CAD EYE) systems support endoscopists in identifying gastric neoplasms during esophagogastroduodenoscopy (EGD).
- Real-world clinical evaluation is crucial for assessing the performance of these advanced diagnostic tools.
Purpose of the Study:
- To evaluate the clinical performance of CAD EYE using white-light imaging (WLI) and linked color imaging (LCI) for gastric neoplasm detection.
- To compare the sensitivity of WLI-CAD EYE and LCI-CAD EYE in a prospective, multicenter trial.
Main Methods:
- A prospective, multicenter, non-randomized trial involving patients with confirmed gastric neoplasms.
- Sequential observation of lesions using WLI-CAD EYE and LCI-CAD EYE during EGD.
- Primary endpoint: sensitivity of CAD EYE for known gastric neoplasms.
Main Results:
- LCI-CAD EYE demonstrated high overall sensitivity (96.5%) for gastric neoplasms, exceeding the primary endpoint threshold.
- WLI-CAD EYE showed 92.0% sensitivity, with lower performance for small lesions (<10mm) and anterior wall locations.
- LCI-CAD EYE maintained high sensitivity (≥90%) across all analyzed subgroups.
Conclusions:
- LCI-CAD EYE is a highly sensitive tool for detecting gastric epithelial neoplasms in clinical practice.
- The system effectively supports endoscopists in real-world settings, particularly with LCI enhancement.
