The Role of ctDNA Testing in Colorectal Cancer Management: Exploring Its Use Alongside Imaging in Challenging Cases

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

Panelists discuss how circulating tumor DNA (ctDNA) testing serves as a complementary tool to traditional imaging in challenging colorectal cancer cases, offering molecular-level insights that can detect disease recurrence earlier, resolve ambiguous radiographic findings, and inform treatment decisions when conventional assessment methods yield inconclusive results.
