First seen Oct 31, 2025 · Last updated Apr 28, 2026 · Updated 25 times
Summary
This study looks at whether a simple blood test can help doctors decide if rectal cancer patients can avoid surgery. Researchers will measure tiny bits of tumor DNA in the blood (ctDNA) before, during, and after standard treatment. The goal is to see if changes in ctDNA levels can show which patients have a complete response to treatment, allowing them to keep their organs. About 50 adults with stage II or III rectal cancer will take part.
