Sasaki et al. developed a pre-operatively assessable, continuous-risk score, Hazard Associated with Liver Transplantation for Hepatocellular Carcinoma (HALT-HCC), which associated the MELD-sodium, tumour burden score, AFP-value, year of LT, underlying cause of cirrhosis, NLR, locoregional therapy and Milan criteria status [32]. Here, AFP is linked to hepatocellular carcinoma.
