HLA-C and neoplasm: There was positive correlation between the magnitudes of fold change of differentially expressed genes in patient plasma samples and the magnitudes of fold change of genes expressed in patient tumour samples: BCL2L1, CCL4, CSF2, CXCL5, CXCR2, GBP1, GZMB, HLA-A, HLA-C, IL13, MIF, NFKB1, PTGS2, and STAT3 (Spearman r = 0.6344, n = 14, p = 0.017), see Fig. 4a.
