The mean expression of WNT1, WNT3A, WNT5A, and WNT5B by tumor cells was respectively 13.55% ± 0.89, 19.16% ± 0.94, 42.47% ± 1.35, and 3.74% ± 0.26 positive cells, which coincides with a moderate expression of WNT1 and WNT3A, a weak expression of WNT5B, but an intense cytoplasmic expression of WNT5A in the three histologic subtypes (Figure 10). This evidence concerns the gene WNT1 and neoplasm.
