Subsequent multivariate analysis revealed that independent risk factors for postoperative RFS comprised TIGIT expression (p = 0.006), NKG2A expression (p = 0.042), tumor differentiation degree (p < 0.05), AFP level (p = 0.042), absolute value of lymphocyte count (p = 0.012), and BCLC stage (p = 0.023). Here, AFP is linked to neoplasm.
