Intended Use
Follicular lymphoma (FL) and diffuse large B-cell lymphoma (DLBL) represent the two most common entities of Non-Hodgkin lymphoma (NHL) worldwide with up to 22% and 31% of tumors, respectively. FLs have been classically associated with the translocation t(14;18)(q32;q21) in 70% to 95% of reported tumors, whereas translocations involving the BCL6 proto-oncogene locus in chromosomal band 3q27 are encountered in 6% to 14%. In DLBLs, a BCL6 translocation can be found in up to 40% of cases, while BCL2 translocations occur in 20% to 30%.
