Abstract

AimsTo evaluate stromal histopathological features and immunostaining expression for differential diagnosis of low- and high-grade dysplastic nodules (HGDN) to early and progressed hepatocellular carcinomas (eHCC, pHCC).MaterialsWe evaluated sinusoid capillarisation (SC), solitary artery (SA), ductular reaction (DR), stromal invasion and expression of six biomarkers (GPC3, HSP70, GS, CD34, CK19, EpCAM) in a series of 97 cases.ResultsStromal morphological changes, including SC, DR and SA, exhibited significant differences in differential diagnosis. In one indicator, SC had the best sensitivity (90.00%) and accuracy (85.42%), and SA had the best specificity at 88.89 %. In combinations, SC +and SA +were favourable and optimal. The immunoreactivity of GPC3, HSP70 and GS increased significantly in line with the stepwise progression of hepatocarcinogenesis.ConclusionsStromal histopathology features are useful for diagnosing HGDN, eHCC and small HCC. The immunostaining panel of GPC3, HSP70 and GS can also be supplementary.
