Single-Agent Pixantrone as a Bridge to Autologous Stem Cell Transplantation in a Patient with Refractory Diffuse Large B-Cell Lymphoma.

Abstract

Aggressive non-Hodgkin lymphoma is associated with poor long-term survival after relapse or resistance to chemotherapy. We report a case of aggressive non-Hodgkin lymphoma refractory to first-line R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) and second-line R-DHAP (rituximab, dexamethasone, cytarabine, and cisplatin) chemotherapy treatments. The patient achieved remission with single-agent pixantrone, and received a consolidation with high-dose BEAM (BCNU, etoposide, cytarabine, and melphalan) chemotherapy and autologous stem cell transplantation. He received consolidation radiotherapy on the site of bulky disease. At 20 months from transplant, the disease is in continuous complete remission. The successful use of pixantrone as a bridge to transplant is highlighted, together with the absence of serious side effects.
