Cells of origin, GCB or non‐GCB subtype, and molecular subtypes of DLBCL, such as double‐hit lymphoma (MYC and BCL2 and/or BCL6 rearrangements),24, 35 diagnosed using interphase dual‐fusion fluorescence in situ hybridization were not included in this study. Here, BCL2 is linked to diffuse large B-cell lymphoma.
