Emerging therapies for the treatment of relapsed or refractory diffuse large B cell lymphoma

Diffuse large B cell lymphoma (DLBCL) is an aggressive non-Hodgkin lymphoma, accounting for approximately 30% of lymphoma cases in Canada. Although most patients will achieve a cure, up to 40% will experience refractory disease after initial treatment, or relapse after a period of remission. In eligible patients, salvage therapy followed by high-dose therapy and autologous stem-cell transplantation (ASCT) is the standard of care. However, many patients are transplant-ineligible, and more than half of those undergoing ASCT will subsequently relapse. For those patients, outcomes are dismal, and novel treatment approaches are a critical unmet need. In this paper, we present available data about emerging treatment approaches in the latter setting and provide a perspective about the potential use of those approaches in Canada.
