Purpose: The present study aimed to report the clinical correlations and prognostic significance of microtubule-associated protein-1 (MAP-7) and forkhead box transcription factor-C1 (FOXC1) expression in Egyptian patients with newly diagnosed acute myeloid leukemia (AML). Methods: The study included 80 adults with newly diagnosed AML. Laboratory investigations included complete blood count, morphological examination of bone marrow aspirate, immunophenotyping, conventional karyotyping and molecular study for fms-like tyrosine kinase 3 (FLT3), nucleophosmin-1 (NPM1) and CCAAT/enhancer binding protein α (CEBPA) mutations. MAP-7 and FOXC1 expressions in bone marrow were determined using RT-PCR. Patients were followed for a median (range) period of 6.4 (1.0-35) months. The study outcomes included treatment response, progression-free survival (PFS) and overall survival (OS). Results: Patients with low FOXC1 expression had significantly lower mortality rate (60.0 % versus 84.6 %, p=0.021), significantly longer PFS duration and significantly longer OS. No significant differences were noted between MAP7 expression groups regarding treatment response, mortality rate, PFS duration and OS duration. Interestingly, a significant direct correlation was noted between FOXC1 and MAP7 expressions (r=0.25, p=0.027). Conclusions: FOXC1 and MAP7 expressions are significantly correlated. High expression of FOXC1 in Egyptian population may be related to shorter OS and PFS.
