Clinicopathological analysis of primary intestinal diffuse large B‐cell lymphoma: Prognostic evaluation of CD5, PD‐L1, and Epstein‐Barr virus on tumor cells

Background Primary intestinal diffuse large B‐cell lymphoma (iDLBCL) is rare. In this study, we investigated the clinicopathological features of this disease to further understand the prognostic value of CD5, programmed cell death ligand 1 (PD‐L1), and Epstein‐Barr virus (EBV) on tumor cells.
