First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looks at whether a simple blood test can help doctors decide the best treatment after surgery for stomach or gastroesophageal junction cancer. About 32 people with stage III or IVA cancer will give blood samples before and after surgery to check for tumor DNA. The goal is to see if this approach can improve the chance of being cancer-free one year later.
