Predictive value of microRNA-133a-3p for early urinary incontinence after radical prostatectomy for prostate cancer and its correlation with rehabilitation effects.

AIM

The present study was conducted with the objective ascertaining the clinical implication of microRNA-133a-3p (miR-133a-3p) for urinary incontinence (UI) and rehabilitation effects in prostate cancer after radical prostatectomy.

METHODS

The measurements of miR-133a-3p in urethral tissue samples from prostate cancer patients after radical prostatectomy were carried out via quantitative real-time polymerase chain reaction (qRT-PCR) detection. Receiver operation characteristic (ROC) curve and logistic regression analysis were employed for evaluating the predictive significance of miR-133a-3p for the early UI of prostate cancer patients with radical prostatectomy. Bioinformatics tools were employed for mining the miR-133a-3p possible genes.

RESULTS

An obvious reduction of miR-133a-3p was detected in patients with UI compared with those with urinary continence (UC) (P < 0.001), demonstrating a high diagnostic capacity for patients with UI. Moreover, miR-133a-3p could be an independent predictive index for the early UI in patients with prostate cancer after radical prostatectomy (P < 0.001). Additionally, urine miR-133a-3p was notably increased in the UI patients after rehabilitation (P < 0.001). MiR-133a-3p largely concentered on the muscle-related diseases pathways using bioinformatics tools.

CONCLUSION

MiR-133a-3p was a promising indicator for predicting early UI in patients with prostate cancer after radical prostatectomy.
