Univariate analyses revealed that EZH2/Bcl-2 coexpression correlated to worse objective response rate (ORR), shorter OS and PFS in DLBCL patients treated with RCHOP while multivariate analysis indicated that only elevated LDH level (<i>P</i>=0.001) and presence of B symtom (<i>P</i>=0.008) rather than EZH2/Bcl-2 coexpression were associated with worse OS.
