Successful use of brentuximab vedotin for refractory anaplastic large cell lymphoma as a bridging therapy to haploidentical stem cell transplantation and maintenance therapy post-transplantation.

Brentuximab vedotin (BV) is a monoclonal antibody-drug conjugate that targets CD30, and has been reported to be effective for relapsed/refractory anaplastic large cell lymphoma. We here report a patient who experienced multiple relapses after conventional chemotherapy and autologous hematopoietic stem cell transplantation (HSCT). He achieved a complete metabolic response with BV and proceeded to undergo haploidentical HSCT. After HSCT, he received three doses of BV to prevent an early relapse, and remains in remission 16 months post-transplantation. Our case suggests the potential use of BV both as a bridging therapy to allogeneic HSCT and as a maintenance therapy post-transplantation.
