High LDH1 expression is associated with a poor prognosis in cytogenetically normal acute myeloid leukemia
The prognostic value of IDH1 mutations has been systematically evaluated in acute myeloid leukemia (AML) patients recently.However, the role of IDH1 expression in AML is still under exploration.To investigate the clinical significance, we analyzed the IDH1/2 expression in 320patients with cytogenetically normal AML (CN-AML) by quantitative real-time reverse-transcription polymerase chain reaction (qRT-PCR).High expression of IDH1 was predominant in patients with FLT3-ITD and DNMT3A mutations, and less prevalent in cases with CEBPA double allele mutations.Strong association was observed between high IDH1 expression and low expression of microRNA 181 family.Prognosis was adversely affected by high IDHI expression with shorter overall survival (OS) and event free survival (EFS) in the context of clinical characteristics including age, WBC, and gene mutations of NPMI, FLT3-ITD, CEBPA,IDH1, IDH2, and DNMT3A in CN-AML.Moreover, the clinical outcome of IDH1 expression in terms of OS, EFS and complete remission rate still remained in multivariate models in CN-AML.Importantly, the prognostic value was validated using the published microarray data from 79 adult patients treated according to the German AMLCG-1999 protocol.Our results demonstrated that high IDH1 expression is associated with a poor prognosis of CN-AML.
