Except for miRNA-125b expression marginally correlated with pT- stage (p = 0.042), the ISH signals in cancer tissue of the needle biopsies showed poor correlation of the 6 miRNAs with any of the clinical variables, pre-biopsy PSA, GS in needle biopsies and RRP specimens, pT-stage, and D’Amico/NCCN risk profiles (Table 5). This evidence concerns the gene KLK3 and cancer.
