No statistically significant difference was detected between the mean of SLUG and P4HA2 expression regarding patient age (p = 0.051and p = 0.052) respectively, gender (p = 0.392 and p = 0.369) respectively, tumor grade (p = 0.114 and p = 0.242), respectively, and the grades of poorly differentiated clusters (p = 0.690 and p = 0.663) respectively (Table 2). This evidence concerns the gene P4HA2 and neoplasm.
