Summary

This study aims to learn more about how the body responds to standard treatments for rectal cancer, including chemoradiation and chemotherapy. Researchers will analyze participants' blood, tissue, and scans to see if these tests can predict whether the cancer improves, worsens, or stays the same. The study involves 60 adults with rectal cancer who are about to start standard therapy.
