Using fluorescence in situ hybridization with an MYC break-apart and MYC-IGH fusion probe, we found that 13/39 evaluable IB-DLBCLs (33%) harbor translocations involving MYC, in contrast with only 5/68 (7%) in the non-IB-DLBCL group (P<0.01).     ///    "In conclusion, IB-DLBCLs are genetically characterized by frequent MYC-IGH translocations that often occur without additional BCL2 and/or BCL6 translocations. "    ///    Diffuse large B-cell lymphomas of immunoblastic type are a major reservoir for MYC-IGH translocations..
