BCL6 and lymphoma: In this study, by including lymphomas potentially carrying BCL2-R and/orBCL6-R, i.e. FLs and DBCLs, and lymphomas notoriously without such translocations, we aim to validate the diagnostic performance of the FlexISH BCL2/BCL6 DistinguISH Probe in formalin-fixed paraffin-embedded, comparing to the efficacy of the classical FISH method using single break-apart probes.
