An Update on the Treatment of Lymphoma Ted Wun, M.D., F.A.C.P. Professor of Medicine and Chief In consultation with Joseph Tuscano, M.D. Professor of Medcine Division of Hematology Oncology, UC Davis SOM Objectives • To have a better understanding of the role of maintenance Rituximab after initial induction therapy for indolent lymphoma • Elucidate the role of dose dense chemotherapy in the management of diffuse large cell lymphoma • Examine the role of Lenalidomide in the management of lymphoma • Have a better understanding of the up-front management strategies for indolent lymphoma-answer the question “is there a new standard of care?” The Role of Rituxan for Induction and Maintenance of Indolent Lymphoma Unresolved questions • How does Rituximab maintenance compare with retreatment at progression? • Will newer, more effective induction regimens eliminate the need for Rituximab maintenance? • What are the best endpoints for Rituximab maintenance trials? – ORR, PFS, OS, QOL ? What is the Role of Rituxan for Purging Prior to Auto PSCT and Maintenance After EBMT-Lym-1 Conclusions • Rituximab maintenance significantly prolongs PFS post AutoPSCT for relapsed indolent NHL • Rituximab purging does not have a significant effect on PFS •Consistent with prior studies, AutoPSCT produces durable remissions in patients with relapsed indolent NHL and may be curative in some patients Maintenance rituximab for FL Richard Fischer ASCO 2010 The role of Lenalidomide for the treatment of lymphoma Francisco Hernandez-Ilizaliturri, MD,1 George Deeb, MD,2 Pier Luigi Zinzani, MD,3 Stefano A.
