What is the difference between double-hit and double-expressor lymphoma?
DLBCLs with co-expression of MYC and BCL2 are called double-expressor lymphomas (DELs); whereas double-hit lymphomas (DHLs) have MYC and BCL2 or BCL6 rearrangement as detected by fluorescence in situ hybridization (FISH) or standard cytogenetics and are currently classified by the World Health Organization as high …
