FLI1 and diffuse large B-cell lymphoma: Univariate survival analysis, according to FLI-1 expression dichotomized by a median H-score cutoff (60 for PBL and 91 for DLBCL), revealed that high FLI-1 expression was associated with poorer overall survival in patients with PBL (log-rank test, p = 0.019) (Fig. 5a).
