| Abstract | ||||
| Background: Diffuse large B-cell lymphoma (DLBCL) is considered the commonest subtype of non-Hodgkin lymphoma (NHL) in the world. It is a refractory disease with a high mortality rate due to frequent relapses. Several prognostic parameters are now widely studied for risk stratification and achieving a better outcome. Objectives: In this study, we aim to assess the prognostic value of immunohistochemical expression of CD10, BCL6, and MUM1 independently as surrogate markers for cell of origin (COO) classification of DLBCL and their correlation with clinicopathological characters and survival. Patients and methods: This is a retrospective study conducted on 63 cases of DLBCL, NOS. Full-faced sections were constructed and immunostained for CD10, BCL6, and MUM1. Results: CD10 expression was associated with early-stage (P=0.003), normal serum LDH level (P=0.022), absence of B symptoms (P=0.019), low international prognostic index (IPI) and age-adjusted-IPI (P=0.001) and also associated with longer progression free survival (PFS) (P=0.006). BCL6 expression was associated with centroblastic variant (P=0.005), good ECOG performance status (P=0.038) and low IPI (P=0.004) and also associated with better overall survival (OS) (P=0.028) and PFS (P=0.018). MUM1 expression was associated with advanced-stage (P=0.002) while no significant association was detected with other clinicopathological parameters or survival. Conclusion CD10, BCL6, and MUM1 can be used independently as prognostic immunohistochemical markers for DLBCL that may denote the clinical behavior of the disease and further patients' outcomes. | ||||
