The advent of new molecularly targeted treatment strategies for patients with advanced colorectal cancer places anatomic and molecular pathologists as key players in the delivery of care for this large patient population. Specifically, advanced colorectal cancer encompasses patients presenting with Stage IV cancer, or those who experience a cancer recurrence, explains Dr. Joseph Willis in a new CAP.org article (https://capatholo.gy/37Pdt5A), "Testing of Specimens From Patients With Advanced Colorectal Carcinoma."

Dr. Willis is Vice Chair for Pathology Translational Research and a GI pathologist at Case Western Reserve University and University Hospitals Cleveland Medical Center in Ohio. In this role, Dr. Willis has pursued better understanding of pathogenesis and prediction of outcomes of patients with GI cancers. He also currently serves on the Personalized Healthcare Committee of the CAP. This committee curates the Precision Medicine section of CAP.org (https://capatholo.gy/37R8WiX).
