Gut microbiome profiles as predictors of response to chemoradiotherapy in locally advanced rectal cancer

Gut bacteria profiles before cancer treatment predict who responds well, potentially enabling personalized therapy planning.

This prospective cohort study demonstrates that pre-treatment gut microbiome composition can predict chemoradiotherapy response in locally advanced rectal cancer, with specific bacterial signatures distinguishing complete responders from non-responders. The findings suggest gut microbiome profiling may serve as a non-invasive predictive biomarker to personalize neoadjuvant treatment in rectal cancer.
