As we lacked data on cell of origin and chromosomal translocations (MYC and BCL2 or/and BCL6), we were unable to compare models integrating biologic prognostic markers reflecting recent advances in DLBCL's genomics, molecular biology, immunology, and radiology, further limiting comparisons with other potentially relevant models.8, 20, 21. Here, BCL2 is linked to diffuse large B-cell lymphoma.
