Salvage immunochemotherapy followed by high‐dose chemotherapy and autologous stem cell transplantation is the standard‐of‐care second‐line treatment for patients with relapsed/refractory diffuse large B‐cell lymphoma after first‐line R‐CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone). Outcomes after receipt of second‐line immunochemotherapy in patients with aggressive B‐cell lymphomas who relapse or are refractory to intensive first‐line immunochemotherapy regimens (etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab [R‐EPOCH], rituximab, hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone alternating with methotrexate and cytarabine [R‐HyperCVAD], rituximab, cyclophosphamide, vincristine, doxorubicin, and high‐dose methotrexate alternating with ifosfamide, etoposide, and cytarabine [R‐CODOX‐M/IVAC]) remain unknown.
