Summary

This early-phase study is testing whether a diet low in the amino acid leucine, given for just three days before surgery, is safe for people with stomach cancer. Researchers will check blood amino acid levels, immune cell changes, and any side effects. The goal is to see if this short dietary change can be used without harm before tumor removal.

What this could mean

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

Active substance: leucine-restricted diet
What this could lead to: If successful, this could point toward a safe, short-term dietary intervention to help prepare gastric cancer patients for surgery.
What could go wrong: This is a very early Phase 1 trial with only 37 participants, so results may not apply widely. The diet is only given for 3 days before surgery, so any benefits are likely small and temporary.
