BACKGROUND: Podoplanin (PDPN), a mucin-type transmembrane glycoprotein, is
expressed in a variety of human cancer types, and contributes to tumor
progression. Our goal was to evaluate PDPN expression in hepatocellular carcinoma
(HCC) using both immunohistochemistry (IHC) and RNAscope in situ hybridization.
MATERIALS AND METHODS: Twenty patients with HCC who underwent partial hepatectomy
with curative intent were retrospectively analyzed. RESULTS: IHC gave positive
results in 11 cases, while RNAscope assay for PDPN detected amplification in 16
cases. A significant association was noted between PDPN protein expression and
histological tumor grade (p=0.036). Four cases that had negative PDPN results by
RNAscope were also negative by IHC, while the remaining five cases with negative
results by IHC were positive by RNAscope. A positive relationship was found
between PDPN mRNA protein expression (p<0.001). CONCLUSION: Our preliminary
results suggest that PDPN contributes to the malignant potential of HCC. RNAscope
proved to be a more sensitive and reliable method than IHC in PDPN detection.
