Deregulation of the Wnt signaling pathway had a role in haematological malignancies. Previous studies reported that lymphoid enhancer factor 1 (LEF1) expression and serum Galectin-3 level could affect clinical parameters and outcome in acute myeloid leukemia patients, but as far as we know, no study has addressed their combined effect on AML patients.<jats:italic>Aim<\/jats:italic>. We studied the expression of LEF1 by real-time qPCR and measured serum level of Gal.3 by ELISA technique in peripheral blood of 69 AML patients and correlated it with different clinicopathological criteria of patients, response, PFS and OS.<jats:italic>Results<\/jats:italic>. We found high expression (LEF1<jats:sup>high<\/jats:sup>) was associated with better OS (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mrow><mml:mi>p<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>0.02<\/mml:mn><\/mml:mrow><\/mml:math>) and EFS (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\"><mml:mrow><mml:mi>p<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>0.019<\/mml:mn><\/mml:mrow><\/mml:math>) compared to LEF1<jats:sup>low<\/jats:sup>, low serum Gal.3 level had better OS (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M3\"><mml:mrow><mml:mi>p<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>0.014<\/mml:mn><\/mml:mrow><\/mml:math>) and EFS (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M4\"><mml:mrow><mml:mi>p<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>0.02<\/mml:mn><\/mml:mrow><\/mml:math>) compared to high serum Gal.3 level.
