Post-operative monitoring for gastric cancer

Post-operative Monitoring of Gastric Cancer Using Circulating DNA in Blood Samples

Observational Suzhou Huhu Health & Technology Inc. · NCT07026240

This study will test a new non-invasive blood DNA test in adults after gastric cancer surgery to see if it can predict or detect recurrence earlier than imaging and common tumor markers.

What this trial studies

This prospective, multicenter observational study will collect blood at multiple time points after gastric cancer surgery to develop and validate a multi-target DNA biomarker panel. The panel will be compared with standard clinical methods such as imaging and tumor markers CA19-9, CEA, and CA72-4. Patients will be followed over time to correlate biomarker changes with confirmed recurrence or metastasis. The study will determine whether the blood biomarkers provide earlier or more reliable detection and prognostic information than current monitoring approaches.

Who should consider this trial

Good fit: Adults with gastric cancer who have had or will have surgery at the participating center, can provide required blood samples, and can give informed consent are ideal candidates.

Not a fit: Patients with serious heart, liver, or kidney dysfunction, prior malignancies, active HIV infection, or those receiving targeted, immunosuppressive, or biological therapies are excluded or may not receive benefit.

Why it matters

Potential benefit: If successful, the test could enable earlier and less invasive detection of recurrence using a simple blood sample, allowing faster treatment decisions and potentially better outcomes.

How similar studies have performed: Similar circulating tumor DNA approaches have shown promise for earlier detection of recurrence in other cancers and emerging data in gastric cancer are encouraging but not yet definitive.
