ASCO GI 2023 | The current state of MRD testing in colorectal cancer

Afsaneh Barzi, MD, PhD, City of Hope, Duarte, CA, provides an overview of the clinical impact of minimal residual disease (MRD) testing in colorectal cancer, and strategies to optimize sensitivity. False negatives may occur during testing, and there is no definite treatment regimen for patients who are MRD positive post-surgery. MRD testing alone should additionally not determine whether patients should receive adjuvant therapy. Dr Barzi also highlights disparities in the use of MRD testing. This interview took place at the American Society of Clinical Oncology (ASCO) 2023 Gastrointestinal Cancers (GI) Symposium in San Francisco, CA.
