Description
Background: The genetically heterogeneous and poor survival group of Philadelphia negative (Ph-) B-ALL group that doesn’t have the most recurrent adult rearrangements (t(9;22); t(1;19); t(4;11)) is collectively referred to as “triple negative” (Ph-/-/-). CRLF2 is frequently altered in adult B-ALL, especially in Ph-like pts (50-75% of cases). Alterations that lead, in the majority of cases, to a CRLF2 overexpression. Adult pts with CRLF2 upregulated have poor outcome and novel strategies are needed to improve it.
Aims: Understand the genomic background of all Ph-/-/- ALL and subsequently clustering Ph-/-/- considering CRLF2 overexpression event, in order to define new biomarkers in these subgroups.
Pts and Methods: Ph-/-/- pts were sequenced by WES (44pts/93 samples) and 92 B-Other pts were analyzed with NGS target seq (NTS) to validate the 8 most mutated genes (Fig1A). GEP were performed on 55 Ph-/-/-, 29 …
