Using Hybrid APC to treat gastric low grade intraepithelial neoplasia

HybridAPC for the Treatment of Gastric Low Grade Intraepithelial Neoplasia (LGIN): a Prospective, Multi-center Study

Not applicable Interventional Chinese University of Hong Kong · NCT04197180

This study is testing if a new treatment called Hybrid Argon Plasma Coagulation can safely remove low-grade stomach growths and prevent them from coming back in people who have these conditions.

What this trial studies

This cohort study investigates the clinical efficacy and safety of Hybrid Argon Plasma Coagulation (APC) for treating gastric low grade intramucosal neoplasia. The study aims to achieve successful ablation, defined as no local recurrence of neoplasia at 12 months post-treatment, verified through follow-up endoscopy and biopsies. Eligible patients will have confirmed gastric low grade intraepithelial neoplasia and will undergo the Hybrid APC procedure under informed consent.

Who should consider this trial

Good fit: Ideal candidates are patients with biopsy-confirmed gastric low grade intraepithelial neoplasia measuring 20 mm or less.

Not a fit: Patients with high grade intraepithelial neoplasia, previous endoscopic treatments, or other significant gastrointestinal conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a minimally invasive option for patients with gastric low grade intraepithelial neoplasia, potentially reducing the risk of progression to cancer.

How similar studies have performed: Other studies have shown promising results with similar endoscopic ablation techniques, suggesting potential efficacy for this approach.
