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.
