GPT and neoplasm: Univariate analysis showed that ALT, aspartate transaminase (AST), α‐fetoprotein (AFP), number of tumours, tumour size, vascular invasion, Edmondson stage, CNLC stage and CD155 expression (HR = 1.98, 95% CI: 1.25–3.14, p = .004) were associated with TTR of HCC patients, while vascular invasion and CD155 expression (HR = 2.92, 95% CI: 1.54–5.55, p = .001) were related to OS of HCC patients (Table 2; Figure S2A,B).
