1 Is there a role of HDT ASCT as consolidation therapy for first relapse follicular lymphoma in the post Rituximab era? Yes Bertrand Coiffier Service d Hématologie Hospices Civils de Lyon Equipe «Pathologie des Cellules Lymphoïdes» UMR 5239 CNRS UCB ENS - HCL The Lymphoma Study Association

2 Treatment of first relapse Patient status Age Performance status Co morbidities Characteristics of relapse On/off therapy Transformation Aggressiveness IPI Initial therapy Components Maintenance Duration of response Toxicities Patient wishes

3 Treatment of first relapse Objectives To obtain the longest survival To reach the longest PFS Try to have a 2 nd CR To obtain the best quality of life Use less toxic regimens even if less CRs Obtain a new CR with long PFS Try not to use agents with toxicity 3

4 Therapeutic strategy in FL Two philosophies Avoid chemotherapy as long as possible rituximab rituximab Tositumomab 90Y Ibritumomab other biologics combinations chemotherapy y Try to reach a CR and have a long duration of CR R CHOP salvage R chemo + autologous transplant biologics y 4

5 Autologous transplant in first relapse The standard of care for DLBCL No standard at all for follicular lymphoma However, why not use high dose therapy with autotransplant (HDT)?

9 Why not do HDT in first relapse? Better to keep it for later Standard chemotherapy of immunotherapy do the same Not demonstrated as standard regimen Do not cure FL patients Too toxic

10 LYSA (GELA) experience No randomized study in relapsing patients Two studies looking at outcome of relapsing patients included in prospective randomized study for 1 st line treatment GELF 86 FL2000 Both showed a benefit of HDT and autotransplant

11 High dose Therapy with ASCT the best option in pts failing 1 st therapy Event free survival after relapse/pd Survival after relapse/pd Sebban, JCO 2008

12 Survival after Relapse or PD in FL patients failing primary therapy Sebban, JCO 2008

13 FL2000 ASCT at time of failure after R CHVP I in patients < 70 years Event free survival Overall survival ASCT N=13 ASCT N=13 No ASCT n=50 No ASCT n=50 Le Gouill et al., Hematologica 2011;96:1128

16 Patients not adequate for HDT Patients not treated with R CHOP Elderly patients (over 65?) Patients with other severe concomitant disease

17 Patients recommended for HDT Early progression after R CHOP PD during maintenance therapy PD after PR with R CHOP PD with high tumor burden PD with transformation

18 The Role of Autologous and Allogeneic Transplantation for Follicular Lymphoma I favor using autologous transplantation for patients with high risk disease who have early relapse following conventional therapy Low NRM (<5%) Risk of MDS/AML with TBI regimens May provide long term disease free survival Conditioning regimens including immunotherapy (radioimmunotherapy or Rituximab) promising Nonmyeloablative allogeneic transplantation provides a potentially curative therapy NRM is significant (15 25%) May provide salvage even following failed autologous transplant D Maloney 4 th Eur Cong Hematol Malignancies

19 Conclusions Not a treatment for all patients Good indication PR or SD after R CHOP Early relapses after R CHOP Transformation New drugs after failure of HDT or in patients not fit for HDT
