To evaluate the clinical implication of NPM1 in DLBCL, NPM1 immunohistochemistry (IHC) was carried out on a representative cohort of 97 R-CHOP-treated DLBCL patients in which CYCLON expression was previously investigated [11] using tissue microarray (TMA)....Kaplan Meier survival analyses revealed that CYCLON/NPM1 double expressors DLBCL were significantly associated with an inferior outcome in terms of progression-free survival (PFS, Figure 2B, p = 0.021) compared to DLBCL expressing only CYCLON.
