PINX1 and metastatic malignant neoplasm in the lymph nodes: Reduced expression of PinX1 in patients was correlated with advanced clinical stage (χ2 = 10.230, p = 0.017), high Gleason score (χ2 = 4.019, p = 0.045), positive regional lymph node metastasis (χ2 = 10.852, p = 0.004) and distant metastasis (χ2 = 7.965, p = 0.005).
