Core binding factor (CBF) acute myeloid leukaemia (AML) represents 5-8% of all AMLs and has a relatively favourable prognosis. However, activating c-KIT mutations are reported to be associated with higher risk of relapse and shorter survival. To verify the incidence and prognostic value of c-KIT mutations in CBF AML, we retrospectively analysed bone marrow samples of 23 consecutive adult patients with de novo CBF AML [14 inv(16) and 9 t(8;21)] treated at a single institution from 2000 to 2011. ⋯ Our results confirm a better prognosis for CBF AML than all other AML categories, and for inv(16) than t(8;21) AML. However, no prognostic value for c-KIT mutational status was found in our series. The association between LDH levels and c-KIT mutation would indicate a more active proliferation for mutated CBF AML.
