DDIT3 and diffuse large B-cell lymphoma: Interestingly, we found that the ABC DLBCL subgroup was associated with better PFS (5-year Kaplan–Meier PFS estimates: G-CHOP 54.3% and R-CHOP 55.7%) than reported in retrospective population analyses of previously untreated patients with DLBCL treated with R-CHOP (5-year Kaplan–Meier PFS estimates: R-CHOP 46% [17] and 48% [18]).
