Continuous variables are reported as the median and interquartile range. . CRC = colorectal cancer; T stage = tumor stage; N stage = node stage; TNM stage = tumor node metastasis stage; CRLM = colorectal liver metastases; CEA = carcinoembryonic antigen; CA19-9 = carbohydrate antigen 19-9; IQR = interquartile range; R0 resection = hepatectomy on patients with clear histological margins; CRS = clinical risk score.
