Furthermore, while TFAP2A and TFAP2C overexpression were significantly correlated with SqD in the TCGA cohort (p = 8.28E−10 and p = 0.00457, respectively; Wilcoxon Rank sum; Supplementary Fig. S6), neither was associated with tumor stage, presence of lymph node metastases, lymphovascular invasion or vital status in the TCGA cohort (Supplementary Fig. S6). This evidence concerns the gene TFAP2A and neoplasm.
