Stomach cancer hope: triple therapy may boost tumor clearance before surgery

NCT ID NCT07408609

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

Summary

This phase II trial tests whether adding low-dose radiotherapy and the immunotherapy drug tislelizumab to standard chemotherapy can improve outcomes for people with locally advanced stomach or gastroesophageal junction cancer. About 114 participants will be randomly assigned to receive either the combination therapy or chemotherapy alone before surgery. The main goal is to see if the combination leads to a higher rate of complete tumor disappearance (pathological complete response) at the time of surgery.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

tislelizumab (an immunotherapy drug), oxaliplatin, capecitabine, and low-dose radiation

What this could lead to

If successful, this combination could improve the chance of eliminating all visible cancer before surgery, potentially leading to better long-term outcomes for patients with locally advanced gastric cancer.

What could go wrong

This is a small, early-phase (phase II) trial, so results may not be definitive. Adding immunotherapy and radiation to chemotherapy may increase side effects, and the approach might not work better than chemotherapy alone.
