Besides, since this study was retrospectively conducted, and most patients were diagnosed prior to the reclassification of patients with MYC and BCL2 or/and BCL6 rearrangements (the so-called double-hit lymphoma [DHL] or triple-hit lymphoma [THL]) as a new category in the high-grade B-cell lymphoma in 2016 [62], the information on the proportion of patients with DHL or THL was unavailable. Here, BCL2 is linked to B-cell non-Hodgkin lymphoma.
