Background:
Recently various molecular markers and global gene expression profiling have been investigated to improve risk profile characterization of AML with normal cytogenetics. Our main objective is to investigate the prognostic impact of brain and acute leukemia, cytoplasmic (BAALC) expression in AML with normal karyotype.
Methods:
BAALC expression was analysed using quantitative real time (QRT) PCR.
Results:
High expression was detected in 22 of 45 patients (48.9%) and its expression did not correlate with the clinical parameters of patients. High BAALC expressers had significantly lower incidence of CR (22.7% vs. 73.9%; p = 0.001), higher mortality rate (72.1% vs. 39.1%; p = 0.023), showed significantly shorter DFS (mean 4.5 vs. 13.21 months, p < 0.001), and inferior overall survival (7.02 vs. 15.02 months, p < 0.001). Multivariable analysis confirmed high BAALC expression as an independent risk factor for DFS and OS.
Conclusions:
BAALC expression is an important prognostic factor in AML patients with normal karyotype and its incorporation into novel risk-adapted therapeutic strategies will improve the currently disappointing cure rate of this group of patients.
