While patients with double-hit lymphoma (DHL) are now frequently treated with intensive front-line immunochemotherapy, outcomes for those who fail these regimens and subsequently receive curative-intent second-line immunochemotherapy are unknown. We identified 55 such patients who achieved an overall/complete response rate of 29%/11%, median progression-free/overall survival (PFS/OS) of 2/5·1 months and one-year PFS/OS of 10/19% following the start of second-line therapy. These outcomes may serve as a standard against which future second-line treatment strategies for relapsed/refractory DHL can be measured and justify investigation of non-cytotoxic therapies in the second-line setting for these patients.
