First seen Jan 19, 2026 · Last updated May 16, 2026 · Updated 18 times

Summary

This study looked at 60 adults with a type of rectal cancer to see if the bacteria in their gut and mouth could predict how well their cancer responds to chemotherapy and radiation. Researchers collected stool and saliva samples before treatment and used machine learning to analyze the bacteria. The goal was to build a model that could forecast tumor shrinkage, but this was an observational study, not a treatment trial.
