Which predicts survival better: shrinking the tumor or clearing the lymph nodes?
NCT ID NCT07557316
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at 100 adults with advanced rectal cancer who received total neoadjuvant therapy (a combination of chemotherapy and radiation before surgery). Researchers want to see whether the response in the lymph nodes or the primary tumor better predicts how long patients stay cancer-free and survive overall. The goal is to improve how doctors assess treatment success.
