What this trial is about
The objective of this project is to determine in a non-invasive manner (fecal samples) the predictive value of the intestinal microbiota and the presence of genotoxin-producing bacteria on the response to neoadjuvant treatment in rectal cancer. This could lead to a better understanding and selection of patients for personalized treatment in rectal cancer.
