Short-Course radiation may boost immunotherapy and chemo for stomach cancer

NCT ID NCT07674342

First seen Jun 29, 2026 · Last updated Jun 30, 2026 · Updated 1 time

Summary

This study investigates whether adding a short course of radiotherapy before surgery, alongside a PD-1 inhibitor (serplulimab) and chemotherapy (SOX), can improve outcomes for people with locally advanced upper stomach or gastroesophageal junction cancer. Participants are randomly assigned to receive either the full combination (radiotherapy plus drugs) or drugs alone before surgery, followed by additional drug therapy after surgery. The main goal is to see if the combination leads to a complete disappearance of cancer cells in the removed tissue.

What this could mean

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

Active substance

Serplulimab (PD-1 inhibitor) combined with SOX chemotherapy (S-1, oxaliplatin), with or without short-course radiotherapy

What this could lead to

If successful, this approach could improve the chance of complete tumor removal and long-term control for people with locally advanced stomach cancer.

What could go wrong

This is a mid-stage trial with 146 participants, so results may not apply to all patients. Adding radiotherapy may increase side effects, and the treatment involves chemotherapy and immunotherapy, which can cause significant adverse reactions.
