Abstract/OtherAbstract:
In acute myeloid leukaemia with normal karyotype (CN-AML), gene mutations (e.g. NPM1, FLT3, CEBPA ) as well as deregulated gene expression affect outcome. High expression of ID1 was described as a negative prognostic factor. We have shown that CEBPA regulates ID1 expression. Therefore, we analysed the prognostic impact of ID1 expression in 269 patients (aged 16-60 years) with CN-AML in the context of other molecular markers, particularly CEBPA mutations. ID1 (high) status was an independent negative prognostic factor for overall survival (OS) in multivariate analysis when analysed together with age, extramedullary disease, platelets, expression of BAALC and WT1, FLT3-internal tandem duplication, NPM1, WT1 single nucleotide polymorphism rs16754 and IDH1. ID1 expression was higher in CEBPA wildtype patients than in patients with monoallelic CEBPA mutations and these patients showed higher ID1 expression compared to patients with biallelic CEBPA mutations. Thus, when CEBPA mutations were considered, ID1 expression lost its prognostic impact. Likewise, the negative impact of ID1 (high) status on relapse-free survival (RFS) was lost when CEBPA mutations were included in the analysis. In CEBPA wildtype patients, ID1 expression had no impact on complete remission-rate, OS or RFS. In conclusion, CEBPA mutations seem to deregulate ID1 expression. Therefore, ID1 expression is not an independent prognostic factor in CN-AML.
