Real World Data on Ibrutinib Use in PCNSL Rel/Ref

Sponsor: IRCCS San Raffaele

Summary

PCNSL is a rare and aggressive subtype of B lymphoma that has been recognized as a distinct disease entity in the latest edition of the WHO Classification of Tumors of Haematopoietic and Lymphoid Tissue and is defined as DLBCL that develops exclusively in the brain parenchyma, spinal cord, leptomeninges and eye. In patients under 70 years of age without severe comorbidities, first-line treatment with induction chemo-immunotherapy according to the MATRix scheme (Methotrexate, Cytarabine, Tiothepa, Rituximab) and subsequent consolidation with HDCT followed by ASCT achieved the best results in terms of PFS and OS. Data on patients enrolled in a randomized phase 2 study showed an OS of 70% at a median FU of 88 months. In patients\> 70 years of age or with low KPS, the prognosis remains significantly lower in the younger population. Several population studies have shown a stable increase over the past 30 years in terms of PFS and OS in patients aged under 70 years, while in patients over 70 years or with KPS \<70%, the survival curves are not satisfactory. in part because these patients are often referred to BSC alone, despite the benefit in PFS and OS demonstrated with HD-MTX-based treatments (≥1 g / m2) combined with oral alkylating agents or cytarabine in high doses.
