EZH2 and neoplasm of hypopharynx: Higher EZH2 expression seems to characterize hypopharyngeal tumors when compared to either oral cavity or laryngeal malignancies (percentage of positive cells, control group; oral cavity 60% [IQR: 20–90] or larynx 40% [IQR: 10–80] vs. hypopharynx 80% [IQR: 60–90]; Dunn’s post hoc p < 0.05).
