HP and hepatocellular carcinoma: Combinations of sialylated and fucosylatedtetra-antennary glycopeptides are significantly expressed in the HCCgroup, including N5H6F1S3 (30.6 ± 11.3-fold) at N-211, N6H3F1S1(29.1 ± 13.7-fold) at N-241, and an exclusive presence of N3H6S1(2462.3 ± 766.8) at N-184, suggesting their potential as Hp markersfor HCC detection.
