Popis: BACKGROUND: IDH1-mutation and MGMT-promoter methylation are established prognostic markers in glioblastoma multiforme (GBM); however, invasive procedures are needed to obtain the required tumor tissue. Metastasis-associated in colon cancer-1 (MACC1) has been established as a prognostic plasma marker for several solid cancer entities. Here, we evaluated circulating MACC1 transcripts for prediction of clinical outcome and therapy response in GBM. MATERIAL AND METHODS: Plasma samples were collected from 45 GBM patients (31 IDH1 wildtype (wt), 5 IDH1R132H, 9 unspecified) before surgery. The patients’ clinical course was followed for 24 months. Samples from 15 healthy volunteers served as controls. MACC1-transcript levels, determined by qRT-PCR, were correlated with patient overall survival (OS) and clinical data of known prognostic significance. Cut-off values for Kaplan-Meier analyses were determined by ROC calculations. Cluster analyses were performed. RESULTS: MACC1 transcripts were higher in patients plasma compared to healthy controls (P
