KLK3 and metastatic malignant neoplasm in the lymph nodes: The results established the significance of lncRNA-ATB expression (P < 0.001), and other clinicopathological parameters including histological grade (P = 0.020), preoperative PSA level (P = 0.002), Gleason score (P = 0.049), pathological stage ( < 0.001), lymph node metastasis (P = 0.025) and angiolymphatic invasion (P = 0.011) for independent prognostic predictors of BCR-free survival of PC patients [2].
