1. A method for determining the oxygen status of cancer in an individual, comprising: i) in a sample comprising cells of said cancer, ii) determining the transcriptional level of expression of the ADM gene (SEQ ID NO: 1) or a variant that is at least 95% identical to it, iii ) correlation of the indicated transcriptional level of ADM gene expression with the expression level of at least one reference gene; and iv) assessment of the oxygen status of the cancer by comparing the correlated transcriptional expression level iii) with a predefined correlated trans scriptural expression level ADM.2. The method of claim 1, comprising: i) in a sample comprising cells of said cancer, ii) determining a transcriptional level of ADM expression and at least one additional gene selected from the group consisting of ANKRD37 (SEQ ID NO: 3), P4HA2 ( SEQ ID NO: 12), NDRG1 (SEQ ID NO: 10), SLC2A1 (SEQ ID NO: 15), P4HA1 (SEQ ID NO: 11), LOX (SEQ ID NO: 9), C3orf28 (SEQ ID NO: 6 ), BNIP3L (SEQ ID NO: 5), BNIP3 (SEQ ID NO: 4), EGLN3 (SEQ ID NO: 7), PDK1 (SEQ ID NO: 13), PFKFB3 (SEQ ID NO: 14), KCTD11 (SEQ ID NO: 8), ALDOA (SEQ ID NO: 2) and variants that are at least 95% identical to any of the indicated genes, iii) the correlation of the indicated transcriptional level of ADM gene expression and the specified at least at least one additional gene with an expression level of at least one reference gene, and iv) an assessment of the oxygen status of said cancer by comparing a correlated transcriptional expression level iii) with a predetermined correlated transcriptional expression level of ADM and said at least one additional gene. 3. The method of claim 1 or 2, wherein the transcriptional expression level is at least 2, preferably at least 3, more preferably m1.
