BCL6/BCL2 and MYC Alterations Drawing the Gray Zone between Diffuse Large B-cell Lymphoma and Double, Triple Hit Lymphoma

Abstract

Salamoon M

Diffuse large B-cell lymphoma (DLBCL) Diffuse large B-cell lymphoma (DLBCL) is an aggressive type of non- Hodgkin lymphoma that develops from the B-cells in the lymphatic system. Under the microscope, large malignant lymphocytes are seen diffusely throughout the specimen. Diffuse Large B-Cell Lymphoma (DLBCL) accounts for 20– 30% of all lymphoid malignancies. This subtype forms distinct morphological, molecular, and phenotypic variants. Therefore, it is of a great value to classify diffuse large B-cell lymphoma according to gene expression profiling into germinal center B-cell subtype, activated B-cell subtype, and unclassified subtype. The outcomes vary between these subtypes, and the germinal center B-cell subtype has a better outcome with the current standard rituximab, cyclophosphamide, hydroxydaunorubicin, vincristine, and prednisone (R-CHOP) immunochemotherapy.
