Value Of Evi1 Gene Expression Level In Adult Acute Lymphoblastic Leukemia (All): A Study From The Group For Research On Adult All (Graall)

Background:EVI1 gene overexpression is found in approximately 10% of acute myeloid leukemia (AML) patients, with a higher frequency seen in AML carrying chromosome 3q26 abnormality or MLL gene rearrangement, and associated with a dismal prognosis. Deregulation of EVI1 expression has also been reported in ALL, but its prognostic impact is unclear. Here, we retrospectively analyzed EVI1 expression in a large cohort of adult ALL patients, its correlation with ALL subsets, and its impact on patient outcome.
