Anatomic Resection Is Not Required for Colorectal Liver Metastases with RAS Mutation

Non-anatomic resection (NAR) has emerged as a safe and effective technique for resection of colorectal liver metastases (CRLM). More recently, RAS mutation has been identified as an important indicator of aggressive disease, which may require anatomic resection (AR). In this retrospective study, we compared the long-term outcomes of AR versus NAR in CRLM patients with and without RAS mutations. Patients with known RAS mutation status who...
