CK19 and GPC3 expression in different histological variation of HCC.
Thin trabecular HCC was usually accompanied by the pseudoglandular structure (blue arrow head). This histological variant mostly showed CK19−/GPC3− expression (A). Majority of SHCCs showed CK19+/GPC3+ expression. But nearly half of CK19+/GPC3+ cases with thick trabecular structure also showed abundant fibrous stroma. According to the parenchymal cell to fibrous stroma ratio, they do not fully meet the diagnostic criteria of SHCC (B, C). Most of the compact form of HCC present with CK19−/GPC3+ expression. CD34 staining showed that sinusoid-like blood spaces were not abundant compared to other histological variants (D).

The log-rank test showed a significant difference among the survival curves of three immunosubtypes of HCC (log-rank statistic = 22.61, d.f. = 2, P < 0.01).
