Clinical significance of MYC expression and/or "high-grade" morphology in non-Burkitt, diffuse aggressive B-cell lymphomas: a SWOG S9704 correlative study.

ABSTRACT: The clinicopathologic findings in Burkitt lymphoma (BL) and diffuse large B-cell lymphoma (DLBCL) may show significant overlap, and MYC abnormalities, found in all BLs, also occur in a subset of DLBCL. The 2008 World Health Organization classification introduced the category of "B-cell lymphoma, unclassifiable, with features intermediate between DLBCL and BL" (BCLU) in recognition of this overlap, but the clinical significance of BCLU (ie, "high-grade") morphology and the relationship between BCLU morphology and MYC abnormalities remains unclear. In this study, we identified 260 cases of non-Burkitt, diffuse aggressive B-cell lymphomas from SWOG S9704, a phase 3 randomized study of standard immunochemotherapy versus autologous stem cell transplantation. Of these, 31 cases (12%) showed BCLU
