Univariate independent prognostic analysis showed that age (p < 0.001), tumor grade (p < 0.001), PCDH18 (p < 0.05), PPL (p < 0.01), DEPP1 (p < 0.01), VASN (p < 0.001), KCNE4 (p < 0.001), MYBPH (p < 0.001), C5AR2 (p < 0.01), and MARCH4 (p < 0.01) gene expression levels were significantly different (Table 3). This evidence concerns the gene KCNE4 and neoplasm.
