Individuals over the age of 60 years, these with LEF1high expression showed a higher median survivalRESULTSLEF1 expression and pretreatment patient characteristicsThe clinical and biological characteristics of your sufferers included inside the study are listed in Table 1. Sufferers with LEF1high expression had reduced white blood cell (WBC) counts at baseline (1.8 vs 12.0 x109/L; p 0.0001), and had been less most likely to carry a FLT3-ITD than LEF1low patients (12.8 vs 35.9 , respectively, p = 0.02). The association in between LEF1low and also the presence of FLT3-ITD was also confirmed when the 11 (14.1 ) patients with FLT3-TKD were included amongst individuals with FLT3 mutations (p = 0.03) or, on the contrary, in the group of FLT3 wild kind individuals, as compared to these bearing FLT3-ITD (p = 0.03). Early death occurred in 9 (23 ) instances inside the LEF1low group versus no case in the LEF1high group (OR = 0.04; p= 0.002). Employing the PETHEMA relapse threat criteria [16], there were 24 (31 ), 40 (51 ), and 14 (18 ) individuals with high, intermediate and low-risk relapse, respectively. LEF1low expression was related having a larger frequency of a high relapse danger score (53.9 vs 7.7 , OR=0.07; p 0.0001).
