Could surgery after chemo double survival for advanced stomach cancer?
NCT ID NCT07241715
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether surgery to remove stomach cancer that has spread to the abdomen can help people live longer when done after chemotherapy. About 300 adults whose cancer responded well to initial treatment will be randomly assigned to either have surgery plus more therapy or continue therapy alone. The main goal is to see if surgery improves overall survival and quality of life.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Conversion surgery (surgery to remove the stomach tumor and cancer spread) plus systemic therapy (chemotherapy, targeted therapy, immunotherapy) with or without chemotherapy given directly into the abdomen
- What this could lead to
- If it works, this could show that surgery after chemotherapy helps people with advanced stomach cancer live longer and have a better quality of life.
- What could go wrong
- This is a mid-stage trial, so results are not yet proven. Surgery in this setting carries risks like infection or complications, and the cancer may still come back.
