Colorectal liver metastases (CRLM) affect about 50% of colorectal cancer patients. With the improvement of neoadjuvant chemotherapy and the introduction of targeted therapy, resectability of CRLM and survival rates have improved over time. However, 60-70% of patients still recur. Several pathological and molecular parameters have been described as prognostic factors after CRLM resection. These parameters encompass not only tumoral features, but also non-tumoral ones, such as chemotherapy related liver injury, or factors related to tumour environment, namely Immunoscore. This review summarizes these prognostic indicators to clarify which patho-molecular parameters should be addressed in the pathological report.
