Near complete response in a patient with classical hodgkin lymphoma treated with brentuximab vedotin concurrent with radiation therapy

Abstract

Brentuximab vedotin, an antibody drug conjugate that delivers monomethyl auristatin E into CD-30 expressing cells is FDA approved for the treatment of patients with Hodgkin lymphoma after the failure of autologous stem cell transplantation or at least 2 prior multi-agent chemotherapy regiments. This approval was based on a study that showed an overall response rate of 75% and complete remission in 34%. We present a case of a 24-year-old male with classical nodular sclerosing Hodgkin lymphoma who achieved near complete remission following 5 cycles of brentuximab concurrent with ISRT (involved site radiation therapy) following progression of first-line ABVD (Adriamycin, bleomycin, vinblastine, dacarbazine) and subsequent second-line ICE (ifosfamide, carboplatin, etoposide) chemotherapy. This case not only reiterates the efficacy of brentuximab vedotin in the third-line setting but introduces the role of and need for further clinical trials of combined radiotherapy with brentuximab in Hodgkin lymphoma patients following failure of second-line options.
