Scientists probe tumor environment to predict drug resistance in stomach cancer
NCT ID NCT07692477
First seen Jul 09, 2026 · Last updated Jul 10, 2026 · Updated 1 time
Summary
This study investigates why some stomach cancers do not respond to a standard chemotherapy combination (FLOT) plus the immunotherapy drug durvalumab. Researchers will analyze tumor samples and blood from 250 patients with operable stomach or gastroesophageal junction cancer. By mapping immune and blood vessel-related features in the tumor environment, they aim to identify markers that predict treatment response or resistance. The goal is to improve personalized treatment decisions for future patients.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to better ways to predict which patients will benefit from chemotherapy plus immunotherapy, potentially improving treatment choices.
- What could go wrong
- This is an observational study, not a treatment trial, so it won't directly test a new therapy. The findings may not lead to immediate changes in care.

Who is studied
Adult patients (age \>= 18 years) with histologically confirmed, operable, locally advanced gastric or gastroesophageal junction (GEJ) adenocarcinoma, candidate to perioperative treatment with FLOT plus durvalumab at the participating IRCCS centers. Patients are enrolled consecutively as they start perioperative treatment in clinical practice.
