Therapies for Relapsed Hodgkin Lymphoma: Transplant and Non-Transplant Approaches Including Immunotherapy

Abstract

Autologous stem cell transplant remains the standard of care for relapsed Hodgkin lymphoma (HL). Approximately 50% of patients with chemo-sensitive relapse will be cured with this approach. The optimal pretransplant salvage regimen is controversial, but less toxic combinations seem to be equivalent to more aggressive approaches. For patients with chemo-refractory disease at relapse and those failing autologous transplant, the long-term prognosis remains poor. New approaches such as reduced-intensity allogeneic transplant, monoclonal antibodies targeting the CD30 antigen, Epstein-Barr virus (EBV)-specific cytotoxic T-lymphocytes, and bortezomib are under investigation, but preliminary results are disappointing. New therapies are needed for patients with relapsed HL.
