Summary

This study looks at whether changes in tumor DNA found in the blood (ctDNA) can predict if chemotherapy is working in people with advanced colorectal cancer that no longer responds to standard treatments. About 103 participants will give blood samples and have regular scans to track their cancer. The goal is to find the best time and cutoff for ctDNA changes to signal when the cancer is progressing, which could help doctors adjust treatment sooner.
