CONCLUSIONS (1)

• Standard of care 1L• young fit patients: Cytarabine and rituximab containing chemotherapy

followed by ASCT and Ritximab maitennance (1 every 2 months for 3yrs)• Elderly or unfit pts: R-CHOP followed by R maintenance or BR (without

maintenance ?) , BR

• Treatment options at first relapse:According to nature of first line therapy, duration of treatment, age and co-morbidities:

• R-chemotherapy (BR ? RiBVD ? RBAC ? RHAP ? ) or BTKi-bsaed therapy for patients who reached prolonged DOR after 1L

• BTKi-based therapy for chemo-refractory patients• Discussed allo-SCT for fit chemo-R (or ealry relapse) pts

CONCLUSIONS (2)

• Pending questions in MCL treatment:• How to use new tools like MRD, PET-CT, NGS in daily practice ?

• Are we ready for MRD/PET/NGS –driven strategies ?

• Are we ready to challenge immuno-chemotherapy frontline ?

• What are the mechanisms of resistance to new drugs ?

• Can we predict targeted therapy resistance ?

• What about CAR-T in MCL ?

• ….
