In terms of PFS, BMI (T-NHL: HR = 4.621; 95% CI: 1.706–12.515; p = 0.003; nodal T-NHL: HR = 3.750; 95% CI: 1.252–11.231; p = 0.018; Table 3) and EZH2 expression (T-NHL: HR = 3.754; 95% CI: 1.233–11.426; p = 0.020; nodal T-NHL: HR = 5.147; 95% CI: 1.472–17.998; p = 0.010; Table 3) were independent prognostic markers in both cohorts. Here, EZH2 is linked to non-Hodgkin lymphoma.
