Summary

This study looks at whether a special type of CT scan (spectral CT) combined with a tumor marker (MSI status) can more accurately predict if stomach cancer has spread to nearby lymph nodes. Researchers will compare the CT results with the actual lymph node findings after surgery in 260 patients. The goal is to improve cancer staging and guide personalized treatment, potentially reducing the need for extensive surgery.

What this could mean

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

Active substance: Spectral CT scan
What this could lead to: If successful, this could provide a more accurate, non-invasive way to stage gastric cancer, helping doctors choose the best treatment without relying solely on surgery.
What could go wrong: This is an observational diagnostic study, not a treatment trial. The results may not change current practice, and the technique may not be widely available or accurate enough for all patients.
