Diagnostic and prognostic values of tissue hsa-miR-30c and hsa-miR-203 in prostate carcinoma.
Prostate cancer (PCa) has become a prevalent malignant disease in males globally. Accumulating data suggested that hsa-microRNAs (miRNAs) could be potential biomarkers for tumor diagnosis due to their important roles in the cell cycle. This study investigated the diagnostic and prognostic values of hsa-miR-203 and hsa-miR-30c in PCa tissues. There were 44 pathologically confirmed PCa patients who were enrolled in this study. Tissue samples were collected from both tumor tissues and adjacent normal tissues. RNA was extracted and the expression levels of hsa-miR-203 and hsa-miR-30c in tumor and normal tissues were compared. The receiver operating characteristic (ROC) curves were plotted to evaluate the reliability of hsa-miR-203 and hsa-miR-30c in detecting PCa. All subjects in this study were followed up by 36 months, and the Kaplan-Meier method was conducted to investigate the survival status of PCa patients. The average relative expressions of hsa-miR-203 and hsa-miR-30c in tumor tissues were significantly different from those in adjacent normal tissues (P < 0.001), and the predictive power of the two hsa-miRNAs for PCa prognosis was reliable. Besides that, the average survival times of low-hsa-miR-30c and high-hsa-miR-203 groups were significantly lower than those of the corresponding groups with the log-rank P of 0.015 and 0.023, respectively. In summary, our study suggested that both hsa-miR-203 and hsa-miR-30c are potential biomarkers for detection and prognosis of PCa.
