NCT ID NCT04157322
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a blood test can detect if cancer comes back after surgery for colorectal or appendix cancer that spread to the abdomen. Researchers will collect blood samples from 55 patients before and after surgery to measure DNA changes. The goal is to see if this test is better than standard tumor markers at finding recurrence within one year.
