Cancer informative biomarker signature

The present invention provides a method for deciding a check-point inhibitor (ICI)-based therapy, for a patient suffering from cancer, the method comprising the steps: a) measuring the expression level of the following markers: TGFB1, ZEB1, FAP, ZEB2, GLUL, ENTPD1, GOT1, LDHA, TWIST1, and GLS, in an isolated cancerous biological sample from the patient; b) determining which markers are differentially expressed; and c) classifying the sample, depending on the markers differentially expressed, in one of the following clusters: cluster 1: when ZEB1, ZEB2, ENTPD1, FAP and GLUL are upregulated; cluster 2: when GLS is upregulated; and LDHA, GOT1, ZEB1, ZEB2 and ENTPD1 are downregulated; and cluster 3: when GOT1 is upregulated and TGFB1 and TWIST1 are downregulated.
