Potential Role of Tumor-Informed ctDNA in CRC

Author(s)John L. Marshall, MD, Mark Lewis, MD

Panelists discuss how tumor-informed circulating tumor DNA (ctDNA) testing offers a personalized molecular surveillance strategy that can revolutionize colorectal cancer management through earlier detection of recurrence, real-time monitoring of treatment response, and potential for therapy de-escalation in patients with negative results.
