Brentuximab vedotin in the treatment of CD30+ PTCL.

The development of brentuximab vedotin has opened a new era in the management of peripheral T-cell lymphomas (PTCLs). The improved outcomes with brentuximab vedotin (BV) in combination with cyclophosphamide, doxorubicin, and prednisone (BV-CHP) vs cyclophosphamide, doxorubicin, vincristine, and prednisone in the ECHELON-2 trial are practice changing for common nodal CD30+ PTCLs. Questions regarding the optimal cutoff of CD30 expression for BV-CHP therapy and the efficacy and safety of BV-CHP in less common subtypes of CD30+ PTCL subtypes await clarification.
