Title:
PIM1 and CD79b Mutation Status Impacts the Outcome of Primary Diffuse Large B-cell Lymphoma of the CNS
Published date:

Excerpt:
Forty cases of primary CNS DLBCL treated with high-dose methotrexate-based (HD-MTX) polychemotherapy were subjected to targeted exome sequencing covering 413 genes, including MYD88, CD79b and PIM1....Mutational analysis recognized two groups. The CDP (including MYD88 and/or CD79b mutations) group was identified in 28 cases (70%), and the non-CDP (without CD79b and PIM1 mutations) group was identified in 12 cases (30%)….Patients in the CDP group had a significantly longer 2-year overall survival (OS) (76% and 40%, p=0.0372) than those in the non-CDP group but not a significantly longer 2-year progression-free survival (PFS) (50.0% and 29%, p=0.078).
