Report on recent insight into molecular genetic alterations and target therapy in T-cell acute lymphoblastic leukemia in the 54th ASH annual meeting / 白血病·淋巴瘤

T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy associated with poor prognosis.Increasing data regarding to alteration of gene expression signatures of oncogenes and tumor suppressors involved in the pathogenesis of T-ALL and the major mechanisms of T-cell transformation may contribute to define the biological markers for treatment response and prognosis,and has important clinical implications.In this review,advance knowledge concerning the characteristics of early T-cell precursor ALL,the alteration of TAL1 and NOTCH1 related genes and target inhibiton effects based on these alterations from 2012 the 54th ASH annual meeting ars summarized.
