When the syndecan 2 semiquantitative expression levels in the different tumors were analyzed in relation to their diagnosis features, there was a significant correlation with tumor grade (r Spearman −0.47, p = 0.004) (Figure 4B) although the correlation was not significant in terms of tumor stage (p = 0.2) (Figure 4C). This evidence concerns the gene SDC2 and neoplasm.
