NCI Definition: A biologic subset of diffuse large B-cell lymphomas with a unique molecular signature or expression profile. It represents approximately 50% of diffuse large B-cell lymphomas, and is characterized by the expression of CD10, BCL-6, A-myb, and LMO2 genes, BCL-2 translocation, and c-REL amplification. Morphologically, the vast majority of these lymphomas are centroblastic and a small minority are immunoblastic (ratio20:1). Patients with this type of diffuse large B-cell lymphoma have a more favorable outcome, with a 5-year survival rate of 60% and a median survival of 10 years. [1]

Germinal center B-cell-like diffuse large B-cell lymphomas most frequently harbor alterations in SIN3A, PAX5, MYD88, MAP2K1, and KMT2D [2].

Most Commonly Altered Genes in Germinal Center B-Cell-Like Diffuse Large B-Cell Lymphoma

SIN3A X387_splice, PAX5 Mutation, PAX5 K5I, MYD88 Mutation, and MYD88 L265P are the most common alterations in germinal center B-cell-like diffuse large B-cell lymphoma [2].
