RESUMEN
The central dilemma in treating patients with refractory or relapsed classical Hodgkin lymphoma (RRHL) is the developed resistance to chemotherapy. In recent years, significant advances have been made with the introduction of targeted immunotherapy such as brentuximab vedotin (BV) and nivolumab (NV). As monotherapy, BV and NV have demonstrated high response rates but with an opportunity for disease progression. In other studies, BV or NV is given in combination with chemotherapy as a bridge to hematopoietic stem cell transplantation for curative therapy. This review will investigate the effect of BV and NV as single agents, in combination with each other, or given concurrently with chemotherapy on the response and survival rate of patients with RRHL.
