AFP and neoplasm: Compared to patients who had low peritumoral HBsAg expression, significantly more patients with high peritumoral HBsAg expression had tumor size ≥ 5 cm (p = 0.008), microvascular invasion (p < 0.001), Edmondson grade I and II (p = 0.026), and high level of AFP (p = 0.015) (Supplementary Table S2).
