Prognostic association of double-hit signature (DHITsig) in patients with diffuse large B-cell lymphoma (DLBCL) treated with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone. Kaplan-Meier curves of the DHITsig-positive (DHITsig-pos) germinal center B-cell-like (GCB-) DLBCL versus DHITsig-negative GCB-DLBCL versus activated B-cell-like (ABC-) DLBCL for disease-specific survival (DSS) in the BC Cancer cohort. *P < .001.
