Journal Review in Hepatobiliary Surgery: Genomics of Colorectal Liver Metastasis

Colorectal liver metastasis (CRLM) is a complex clinical situation requiring multidisciplinary management. In this episode from the Hepato-Pancreato-Biliary team at Behind the Knife , we review the genomics of CRLM, discuss a journal article investigating the frequency and impact of these mutations on survival in patients with stage IV disease, and interview the senior author Dr. Jean-Nicholas Vauthey about this research and his career in HPB. Hosts : Timothy Vreeland, MD, FACS (@vreelant) is an Associate Professor of Surgery at the Uniformed Services University of the Health Sciences and Surgical Oncologist at Brooke Army Medical Center Daniel Nelson, DO, FACS (@DWNelsonHPB) is an Associate Professor of Surgery at the Uniformed Services University of the Health Sciences and Surgical Oncologist at William Beaumont Army Medical Center Connor Chick, MD (@connor_chick) is a PGY-5 General Surgery resident at Brooke Army Medical Center Lexy (Alexandra) Adams, MD, MPH (@lexyadams16) is a PGY-4 General Surgery resident at Brooke Army Medical Center Beth (Elizabeth) Carpenter, MD (@elizcarpenter16) is a PGY-3 General Surgery resident at Brooke Army Medical Center Guest: Jean-Nicholas Vauthey, MD (@VautheyMD) is a Professor of Surgical Oncology, Chief of HPB, and Dallas/Fort Worth Living Legend Chair for Cancer Research at MD Anderson. He is the Principal Investigator of the study discussed in the episode in addition to numerous other articles describing the genomics of colorectal liver metastases. Learning Objectives: In this episode, we review basic mutations found in metastatic colorectal cancer and broadly discuss these in a clinical context. We review a journal article from Kawaguchi et al. in which authors analyze prognostic relevance of signaling pathways in patients undergoing resection of CRLM, later validated in an external cohort of unresected patients. We conduct an interview with the senior author of the study regarding relevant methodologic details, next steps in his research, and how to apply this information now and in the future to the care of patients with CRLM.
