We analyzed the influence of the following individual factors on survival in PB-DLBCL patients: age, sex, B symptoms, LDH, lymph node involvement, bone marrow involvement, involved sites, the number of bone sites, stage, and IHC markers (CD10, Bcl-2, Bcl-6, and MUM-1). Here, BCL2 is linked to diffuse large B-cell lymphoma.
