CD5 and diffuse large B-cell lymphoma: Subgroup analysis limited to the DLBCL, not otherwise specified (NOS) cohort (omitting PMBL, THRBCL, and LG because of their more specific biology) revealed that expression of CD5 (p = 0.044) retained its independent prognostic significance with respect to EFS (more sensitive for early events) and expression of FOXP1 (p = 0.004) with respect to OS (later events), while all other biomarkers failed to add prognostic information.
