Purpose: This study aimed to explore the prevalence and predictors of incidental prostate cancer (IPC) after transurethral resection of the prostate (TURP) with negative results on transperineal magnetic resonance imaging (MRI)/transrectal ultrasonography (TRUS) fusion prostate biopsy or TRUS-guided prostate biopsy.
Materials and Methods: Data of 253 patients who underwent TURP with a preliminary diagnosis of benign prostatic hyperplasia (BPH) were evaluated. The prevalence of IPC was calculated. Univariate and multivariate logistic regression analyses were conducted to explore independent predictive factors of IPC.
Results: A total of 253 patients were included. IPC was diagnosed in 12 patients (4.7%). The mean age of the patients and the mean prostate volume were 69.8±7.07 years and 89.3±49.29 mL, respectively. The prevalence of IPC was higher in the TRUS guided prostate biopsy group than in the transperineal MRI/TRUS fusion prostate biopsy group (11 of 203 [5.4%] vs. 1 of 50 [2.0%], p=0.47), but the difference was not statistically significant. Our results indicated that older age (≥70 y) (odds ratio [OR], 1.14; 95% confidence interval [CI], 1.02?1.27; p=0.025) and smaller prostate volume (OR, 0.97; 95% CI, 0.938?0.998; p=0.039) were associated with an increased incidence of IPC after TURP.
Conclusions: Our findings indicate that the prevalence of IPC may be higher among patients who undergo transrectal prostate biopsy before TURP than among those who undergo transperineal MRI/TRUS fusion prostate biopsy. Older age and smaller prostate volume were independent predictors of increasing the risk for IPC after TURP.
