Prostate cancer (PCa) is considered the most common malignancy in men. The aim of this study is to assess the role of serum miR‐15a and miR‐16‐1 expression in PCa development, diagnosis and prognosis aiming to find a specific noninvasive biomarker. This study comprised 70 patients with PCa, 70 patients complaining of benign prostatic hyperplasia (BPH), 30 patients with chronic prostatitis and 70 controls. Circulating miR‐15a and miR‐16‐1 expression was detected by real‐time polymerase chain reaction. Prostate specific antigen levels were measured by enzyme‐linked immunosorbent assay. The expression levels of serum miR‐15a were decreased in PCa patients compared with controls, chronic prostatitis and BPH patients (0.43 ± 0.12, 1.7 ± 0.76, 1.56 ± 0.34 and 1.53 ± 0.65, respectively). The expression levels of serum miR‐16‐1 were decreased in PCa patients compared with controls, chronic prostatitis and BPH patients (0.55 ± 0.23, 2.15 ± 0.87, 2.08 ± 0.54 and 1.96 ±0.61, respectively). Downregulation of miR‐15a and miR‐16‐1 correlated with higher Gleason score (P = 0.002 and P = 0.006, respectively), higher tumor stage (P = 0.001 and P = 0.01, respectively), PCa metastasis (P = 0.002 and P = 0.025, respectively) and lymph node involvement (P = 0.02 and P = 0.007, respectively). Moreover, Receiver operating characteristic curve analysis revealed that combined miR‐15a/miR‐16‐1 and PSA increased the sensitivity and specificity for the diagnosis of PCa (97.1% and 94.3%, respectively) more than prostate specific antigen alone (82.9% sensitivity and 75.7% specificity). Combined serum miR‐15a/miR‐16‐1 expression and PSA level can be used as promising specific noninvasive biomarkers in the diagnosis and prognosis of PCa better than prostate specific antigen alone. © 2018 IUBMB Life, 70(5):437–444, 2018
