Expression of progenitor cell markers in hepatocellular carcinoma: correlation with stage and prognosis

Abstract

Aims: In human hepatocellular carcinoma (HCC), keratin 19 (K19), Epithelial Cell Adhesion Molecule (EpCAM) and CD117 (c-KIT) immunopositivity indicate possible hepatic progenitor cell (HPC) origin. Methods and Results: We assessed the expression of K19, EpCAM and CD117 by immunohistochemistry in 89 HCC from Greek patients (mean age 66.7±11.3 years, male 74.7%) followed-up for 39.625.3 months in correlation with clinico-pathological parameters and survival. K19-, EpCAM- and CD117-specific immunoexpression was detected in tumour cells of 9/89 (10.11%), 12/78 (15.38%) and 3/89 (3.37%) HCC, respectively. K19-positivity tended to correlate with microvascular invasion (p=0.054). In univariate analysis, K19-positivity and microvascular invasion were associated with decreased recurrence-free (RFS) (p<0.001 and p=0.004, respectively) and overall survival (OS) (p=0.002 and p=0.029, respectively). EpCAM- and CD117-positivity did not correlate with survival. K19-positive/EpCAM-positive cases showe ...
