How I Treat Older Patients with Relapsed/Refractory Diffuse Large B-Cell Lymphoma

Diffuse large B-cell lymphoma (DLBCL) is an aggressive, yet curable malignancy, but older patients are at higher risk of relapsed disease as they may not be eligible for full-intensity frontline chemoimmunotherapy or have comorbidities that limit standard treatments. Recent years have brought more treatment options than ever for this patient population, but it remains challenging to determine which can be safely and effectively offered to older patients. Formal determinations of fitness including geriatric assessments remain critical, but there is less guidance as to how to best utilize this tool in the relapsed setting. Chimeric antigen receptor-T cell therapy is accessible to older patients provided they can be supported through the intensive road to this treatment. If relapse occurs despite this or alternative therapies are preferred, many novel therapeutic options and combinations exist with some potential modifications for older adults, such as bispecific antibodies, tafasitamab and lenalidomide, polatuzumab containing regimens, or loncastuximab tesirine. This article provides a summary of our approach to the management of this diverse population of older patients with relapsed or refractory DLBCL.
