AFP and hepatocellular carcinoma: High pre-transplant AFP level (HR, 2.537; 95% CI, 1.372–4.692; P = 0.003), microvascular invasion (HR, 2.671; 95% CI, 1.459–4.890; P = 0.001), viable tumor number (HR, 1.058; 95% CI, 1.019–1.099; P = 0.003), and maximum tumor size (HR, 1.196; 95% CI, 1.046–1.366; P = 0.009) were independent risk factors for HCC recurrence, whereas recipient age ≥ 60 years was associated with a decreased risk of HCC recurrence.
