In addition, higher levels of WNT4 were found in large tumor size (96.60 pg/mL vs. 59.38 pg/mL; P = 0.0087) and tumor with metastasis (111.1 pg/mL vs. 71.73 pg/mL; P = 0.0428), while no relationship was observed between WNT4 expression and age, sex, lymph node metastasis, and differentiation (P > 0.05). Here, WNT4 is linked to neoplasm.
