EPCAM and adenoid cystic carcinoma: In contrast, no statistically significant difference was observed between EpCAM expression and the degree of differentiation, as 50.0% of patients with adenocystic carcinoma had well-differentiated and strong staining, patients with intermediate differentiation had both moderate staining (75.0%) and strong staining (25.0%), and poorly differentiated patients (75.0%) had moderate staining (p-value = 0.104).
