Questions regarding the FLIPI index
Age has a major impact
Number of nodal areasinvolved are not really easyto evaluate Will 18-FDG PET help ?
Young patients with largetumor mass may beconsidered as low risk evenwith one factor (LDH, bonemarrow)

Retarder la mise en route d’untraitement: surveillance armée
Le Watch and Wait est une option acceptable sur le planscientifique:– chez des patients “à faible risque”– 3 études randomisées
• temps médian pour début du traitement ~ 2 ans• mais 15 à 20% des patients ne seront pas traités
pendant 10 ans
Oui, cependant…– Pas toujours facile à accepter pour le patient– … et sans doute pas à l’origine de “progrés”

3) Associer le rituximab avec des cytokines, d’autres Mabs,ou des agents immunomodulateurs ?
- IFN, GM-CSF, IL-2(Davis 2000 ; Sacchi 2001 ; Kimby 2002 ; Bosly 2004, Cartron 2007)- Anti-CD22, -CD40, -CD80, etc…- Lenalidomide = R2 regimen ?
Traitements deslymphomes folliculaires
Ce que nous savons des essais menés avantles anticorps monoclonaux:
– Bénéfice des anthracyclines non démontré– Place des analogues de purines discutée
– Effet positif de l’interféron-α
– Pas de bénéfice évident de l’autogreffe• Peut-être un contrôle de la maladie meilleur pour
les patients les plus graves• Mais au prix d’une toxicité peu acceptable
Cependant, l’obtention d’une RCau premier traitement semble importante

Rationale fo rituximab maintenance
Maintenance therapy against lymphoma more efficient in a state ofminimal residual disase
Long half life of the antibody in vivo– Target level of 25 µg/ml– 95% will have this level if the drug is given every 3 months– Gordan et al, JCO 23:1096-1102, 2005
Rituximab immunological mediated actions?– ADCC– Antigen presentation by dendritic cells??
Good safety profile of the antibody
An international Intergroup study conducted by the GELA
PD/SDoff study
Rituximab maintenance:
1 dose every 8 weeks for 24 months

Les choix thérapeutiques en rechute
– Que veut-on obtenir ?– Quels outils, quels bénéfices ?– Quelles voies de progrès ?
Au moment de la rechute,le choix thérapeutique devient complexe
Possibilités thérapeutiques:– Ne rien faire et surveiller (W&W)– Le rituximab en monothérapie– Les Ac radiomarqués– Les agents alkylants en monothérapie– Les combinaisons de type (FCM, DHAP, MIV…)– L’autogreffe– Entretien par rituximab après une seconde ligne– L’allogreffe– Essais thérapeutiques et nouvelles drogues…
• Bendamustine• Nouveaux anticorps (anti-CD20, autres)• Immunoconjugués (CMC542)• Inhibiteurs du protéasome• Immunomodulation,• Anti-BCL2….
Faut-il réadministrer du rituximab ?

The Role of Autologous and AllogeneicTransplantation for Follicular Lymphoma
• I favor using autologous transplantation for patients with high-risk diseasewho 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
