The univariable analysis showed poorer OS rates in both cohorts exhibiting high EZH2 protein expression compared with those exhibiting low expression (T-NHL: median OS 78.0 vs. 16.0 months; p = 0.011; nodal T-NHL: median OS 124.0 vs. 16.0 months; p = 0.012). Here, EZH2 is linked to non-Hodgkin lymphoma.
