Colorectal cancer diagnosis and treatment during these unprecedented times

Dr. John Marshall of Georgetown University describes how we are innovating at this time in order to meet the needs of our patients with colorectal cancer. He details Signatera, a ctDNA and MRD assay that can be used to detect recurrence significantly faster than standard CEA and can also be used to help guide therapeutic decisions based on response. He provides practical case based information on ways he has used the assay in clinical practice.
