Expression of PSMA in Tumor-Associated Vasculature Predicts Poorer Survival in Patients With Hepatocellular Carcinoma and Is Likely Associated With PD-L1

PSMA (prostate-specific membrane antigen) is a type II transmembrane glycoprotein recently found to be expressed in hepatocellular carcinoma (HCC). We aimed to characterize the expression pattern of PSMA in HCC and its association with clinicopathologic parameters and other biomarkers.
