Abstract

Double hit lymphoma (DHL) and double protein-expressing (MYC, BCL2) lymphomas (DPL) fare poorly with R-CHOP (rituximab + cyclophosphamide, doxorubicin, vincristine, prednisolone); consolidative autologous stem cell transplant (ASCT) may improve outcomes. S9704, a phase III randomized study of CHOP +/-R with or without ASCT enabled evaluation of intensive consolidation. Immunohistochemistry (IHC) identified 27 of 198 patients (13·6%) with MYC overexpression; 20 (74%) harboured concurrent BCL2 overexpression. Four had DHL and 16 had DPL only. With median 127 months follow-up, there is a trend favouring outcomes after ASCT in DPL and MYC protein overexpressing patients, whereas all DHL patients have died irrespective of ASCT.

Keywords: BCL2; MYC; autologous stem cell transplant; double hit lymphoma; double protein lymphoma.
