What this trial studies

This observational study aims to evaluate the prognostic significance of liquid biopsy in patients with locally advanced gastric cancer. It involves collecting circulating tumor DNA from peritoneal lavage and plasma samples at various stages, including before and after surgery. The goal is to determine the predictive power of these liquid biopsies on overall survival and disease-free survival in affected patients. The study will include patients with specific stages of gastric adenocarcinoma undergoing either staging laparoscopy or radical surgery.

Who should consider this trial

Good fit: Ideal candidates are patients with histologically confirmed locally advanced gastric adenocarcinoma who meet specific staging criteria.

Not a fit: Patients with distant metastases, previous chemotherapy for gastric adenocarcinoma, or other significant health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a non-invasive method to better predict patient outcomes in gastric cancer.

How similar studies have performed: Other studies utilizing liquid biopsy techniques have shown promise in various cancers, suggesting potential success for this approach in gastric cancer.
