abstract = {Knowledge of the genomic landscape of chronic lymphocytic
leukemia (CLL) grows increasingly detailed, providing
challenges in contextualizing the accumulated information.
To define the underlying networks, we here perform a
multi-platform molecular characterization. We identify major
subgroups characterized by genomic instability (GI) or
activation of epithelial-mesenchymal-transition (EMT)-like
programs, which subdivide into non-inflammatory and
inflammatory subtypes. GI CLL exhibit disruption of genome
integrity, DNA-damage response and are associated with
mutagenesis mediated through activation-induced cytidine
deaminase or defective mismatch repair. TP53 wild-type and
mutated/deleted cases constitute a transcriptionally uniform
entity in GI CLL and show similarly poor progression-free
survival at relapse. EMT-like CLL exhibit high genomic
stability, reduced benefit from the addition of rituximab
and EMT-like differentiation is inhibited by induction of
DNA damage. This work extends the perspective on CLL biology
and risk categories in TP53 wild-type CLL. Furthermore,
molecular targets identified within each subgroup provide
opportunities for new treatment approaches.},
