Liver metastases from colorectal cancer: A joint ESSO–EAHPBA–UEMS core curriculum collaboration

Colorectal liver metastases (CRLM) are a major indication for liver surgery in Europe, highlighting the need for standardized knowledge and training in surgical oncology. The European Society of Surgical Oncology (ESSO) has updated its core curriculum to provide a structured framework for education. Previous publications have addressed pancreatic, hepatocellular, and biliary tract cancers to support candidates preparing for the European Board of Surgery Qualification (EBSQ) exams in Surgical Oncology and Hepato-Pancreato-Biliary Surgery. However, a dedicated guide for CRLM remains absent.

This article aims to fill that gap by offering a structured reference on CRLM, covering epidemiology, staging, genetics, and diagnosis of metastatic colorectal cancer. It also outlines multidisciplinary treatment strategies, including systemic, surgical, interventional, and palliative approaches. A structured literature review was conducted using PubMed to identify the most updated (inter)national management guidelines, prioritizing recent multicentre studies, systematic reviews, and meta-analyses published from January 2020 to January 2025.

By bridging the gap between the ESSO core curriculum and detailed subspecialty training, this guide provides an essential resource for hepatobiliary surgeons and surgical oncologists. It serves as a valuable tool for those preparing for board examinations while promoting a standardized approach to CRLM education and management across Europe.
