As shown in Table 3, miR-126 expression status (P = 0.01), pathological stage (P = 0.001), lymph node metastasis status (P = 0.03), and positive angiolymphatic invasion (P = 0.001) were all independent prognostic factors for predicting BCR-free survival of patients with PCa. This evidence concerns the gene BCR and posterior cortical atrophy.
