Introduction: Diffuse large B-cell lymphoma (DLBCL) is the most common histotype in non Hodgkin lymphoma, with a peak incidence in the sixth decade. The standard treatment for elderly FIT DLBCL patients is Rituximab-CHOP; in unfit and frail patients, chemotherapy at reduced intensity should be considered.Areas covered: In this article, we will review use of standard therapies and new drugs investigated such as immonomudulating agents (IMiDs), Bruton Tyrosine Kinase (BTK), in fit, unfit, frail and very elderly DLCBL patients.Expert commentary: R-CHOP21 in fit DLBCL patients is still the standard of care, while in elderly unfit patients a reduction of doses of cytotoxic drugs or schemes that avoid antracycline should be considered. The Comprensive Geriatric Assesment based in age, comorbidities and functional abilities of daily living is an important tool in elderly, in order to discriminate between fit, unfit or frail patients. Novel drugs represent valid therapeutic options in relapsed/refractory setting so continued participation in clinical trials should be encouraged.
