Summary

This study looks at whether a simple blood test that finds bits of tumor DNA (ctDNA) can help doctors know if rectal cancer has been fully wiped out by chemotherapy and radiation. About 60 adults with advanced but non-spreading rectal cancer will give blood and tissue samples before, during, and after standard treatment. The goal is to see if the test can predict who can safely avoid surgery and who might need it because the cancer is still there or comes back.
