BCL2 and B-cell non-Hodgkin lymphoma: The analysis of FISH results showed that, as expected from the published literature, BCL2 rearrangements (either alone or as double/triple hits) clustered under the umbrella of GCB (classified by Lymph2Cx), so that the presence of a BLC2 break is, in our series, a highly (100%) specific, but not very sensitive (30%) marker of aggressive B-cell lymphomas of GCB-type.
