Abstract
FLT3-ITDs are linked to higher leukocytes/blasts in acute myeloid leukemia. To evaluate the effect of NPM1 mutations, we correlated NPM1mut status with morphology in 805 adult normal karyotype AML. NPM1mut were found in 391/805 (48.6%), FLT3-ITD in 219/805 (27.2%). Frequencies of FLT3-ITD and NPM1mut cases were continuously increasing by blast decades: NPM1mut from 38/123 (30.9%) in 20-29% blast decade to 70/103 (68.0%) in 90-100% decade (p<0.001), FLT3-ITDs from 15/123 (12.2%) to 58/103 (56.3%) (p<0.001). Mean WBC count was highest in NPM1-mut/FLT3-ITD-positive and lowest in NPM1-wildtype/FLT3-ITD-negative patients (p<0.0001); similar for BM blasts. Therefore, FLT3-ITD and NPM1mut might synergistically stimulate blast proliferation.Entities:
