Summary

This study looks at tiny cancer cells and DNA pieces floating in the blood of people with rectal cancer. Researchers want to see if these blood markers can tell us how the tumor responds to standard treatment. The study includes about 341 people with rectal cancer and healthy volunteers. The goal is to learn more about rectal cancer, not to test a new treatment.
