Scientists hunt for clues in colorectal cancer tissue and blood
NCT ID NCT01762813
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is gathering blood and tumor samples from 1,200 people with colorectal cancer who are having surgery to remove their cancer. Researchers want to look for biomarkers that might help predict how well patients do after surgery. The study does not test a new treatment, but aims to better understand the disease.
