Purpose: Enhancer of zeste homolog 2 (EZH2) is an epigenetic regulator implicated in the pathogenesis of diffuse large B-cell lymphoma, but the prognostic value of its protein expression is uncertain. We evaluated EZH2 expression and its associations with clinicopathological features and survival.Materials and Methods: We retrospectively studied 50 patients with diffuse large B-cell lymphoma treated with rituximab-based immunochemotherapy. EZH2 expression was assessed by immunohistochemistry using an H-score and classified as high (≥150) or low (
