Clinical Challenges in Colorectal Surgery: Management of Metastatic Colorectal Cancer

With the increasing incidence of colorectal cancer in those less than 50 years of age, one must wonder how many patients present with a Stage IV diagnosis. Take a deep dive with us discussing the management of metastatic colorectal cancer by joining our team and guests, Drs. Cathy Eng, Michael D’Angelica, and Nina Sanford. Hosts: - Dr. Janet Alvarez - General Surgery Resident at New York Medical College/Metropolitan Hospital Center - Dr. Wini Zambare – General Surgery Resident at Weill Cornell Medical Center/New York Presbyterian - Dr. Philip Bauer, Assistant Professor of Surgery, Division of Colon and Rectal Surgery, The Ohio State University Wexner Medical Center, Arthur G. James Cancer Hospital - Dr. J. Joshua Smith MD, PhD, Chair, Department of Colon and Rectal Surgery at MD Anderson Cancer Center Guest Speakers: - Dr. Michael D’Angelica MD, FACS – Hepatopancreatobiliary Surgery, Memorial Sloan Kettering Cancer Center, Enid A. Haupt Chair in Surgery, Vice Chair, Education - Dr. Cathy Eng MD, FACP - Division of Hematology and Oncology, Vanderbilt-Ingram Cancer Center, David H. Johnson Endowed Chair in Surgical and Medical Oncology, Professor of Medicine, Hematology and Oncology, VICC Associate Director for Strategic Relations and Research Partnerships, Executive Director, Young Adult Cancers Program - Dr. Nina Sanford, MD – Radiation Oncology, UT Southwestern Medical Center, Chief of Gastrointestinal Radiation Oncology Service, Associate Professor Learning Objectives: 1. Review the epidemiology, prognosis, and common metastatic patterns of metastatic colorectal cancer (mCRC). 2. Discuss the role of systemic chemotherapy and targeted therapies in the first- and subsequent-line treatment of mCRC, including the impact of molecular biomarkers such as MSI/MMR, RAS, BRAF, and HER2. 3. Evaluate the indications and timing of surgical and locoregional therapies for metastatic colorectal cancer, particularly in patients with liver-limited or oligometastatic disease. 4. Describe the multidisciplinary management of mCRC, including the roles of radiation therapy, systemic therapy sequencing, and palliative interventions to optimize outcomes and quality of life.
