Evaluation of BCL6 and MUM1 Expression in Patients with Diffuse Large B Cell Lymphoma (DLBCL) and Their Correlation with Staging and Prognosis of the Disease

Abstract

Diffuse Large B-Cell Lymphoma (DLBCL) is the most common type of Non-Hodgkin Lymphoma (NHL) which includes about (25%) of the cases. Patients with DLBCL have a rapidly growing mass that is located in the neck or abdominal region. Multiple Myeloma Oncogene (MUM1) has an important role in lymphoid cell differentiation. MUM1/IRF4 is as oncogene related to myeloma and translocation (p25; q32), t (6; 14) and leads to a change in the heavy chain of Immunoglobulin (IGH). BCL6 exists in approximately (100%) of follicular cell cancer cases, (100%) of Burkitt lymphoma, (80%) of large B-cell lymphoma, and in more than (80%) of nodular lymphocytic Hodgkin lymphoma cases. BCL6 is related to cancers with a high proliferation cell index. In some studies BCL6 is expressed as a prognostic factor in LBCL patients
