Single agent oral selinexor as a key to potential cure in refractory diffuse large B-cell lymphoma: case report and literature review.

ABSTRACT

Relapsed/refractory diffuse large B-cell lymphoma (DLBCL) portends a poor prognosis, with an estimated overall survival of less than 6 months. In the presented case, a female patient with DLBCL refractory to multiple lines of therapy, including chimeric antigen receptor T-cells, was treated with single-agent selinexor, achieving partial response following 5 months of treatment, which allowed the patient to proceed to potentially curative allogeneic stem cell transplantion. This approach enabled the patient, who would otherwise have been considered a candidate for palliative care, to achieve the most prolonged complete response since her first lymphoma-specific treatment. This outcome implies that early identification of relapsed/refractory patients who may benefit most from this drug - either as a single agent or in drug combinations - is imperative.
