EZH2 and non-Hodgkin lymphoma: In the nodal T-NHL cases, high EZH2 protein expression was associated with both the presence of B symptoms (B symptoms vs. no B symptoms: median 130 vs. 53.8; p = 0.031; Figure 5a) and with a high Ki-67 Index (Ki-67 Index > 65 vs. Ki-67 Index < 65: median 150 vs. 47.5; p = 0.059; Figure 5b).
