Our findings also revealed significant correlations between KPNA2, LPCAT1, KIF2C, and SPP2 expression and three clinical traits, including ECOG (Supplementary Figure 8(b), p < 0.01), vascular tumour cell type (Supplementary Figure 9(a), p < 0.05), and tumour status (Supplementary Figure 9(c), p < 0.05). This evidence concerns the gene KPNA2 and neoplasm.
