Impact of BCL2/MYC Protein Dual Expression and Other Clinical Factors on the Risk of Central Nervous System Progression in Patients with Primary Breast Diffuse Large B-Cell Lymphoma

초록

Background Primary breast diffuse large B-cell lymphoma (DLBCL) has poor outcomes with frequent extranodal failures, particularly in the central nervous system (CNS). Recent studies have reported that cell-of-origin (COO), BCL2/MYC dual expression (DE), and MYC and BCL2 and/or BCL6 rearrangements, so-called double hit (DH) and triple hit, are associated with a high risk of CNS progression in DLBCL; however, the impact of these biologic markers in primary breast DLBCL on CNS progression remains unknown.
