Prospective study of transitional cell carcinoma in the prostatic urethra, and prostate in cystoprostatectomy specimen
(2007) In Scandinavian Journal of Urology and Nephrology 41(4). p.290-296- Abstract
- Objectives. To prospectively evaluate the incidence of transitional cell carcinoma (TCC) in the prostatic urethra and prostate in the cystoprostatectomy specimen, investigate characteristics of bladder tumours in relation to the risk of involvement of the prostatic urethra and prostate and examine the sensitivity of preoperative loop biopsies from the prostatic urethra. Material and methods. Preoperatively, patients were investigated with cold cup biopsies from the bladder and transurethral loop biopsies from the bladder neck to the verumontanum. The prostate and bladder neck were submitted to sagittal whole-mount pathological analysis. Results. The incidence of TCC in the prostatic urethra and prostate in the cystoprostatectomy specimen...

To prospectively evaluate the incidence of transitional cell carcinoma (TCC) in the prostatic urethra and prostate in the cystoprostatectomy specimen, investigate characteristics of bladder tumours in relation to the risk of involvement of the prostatic urethra and prostate and examine the sensitivity of preoperative loop biopsies from the prostatic urethra. Material and methods. Preoperatively, patients were investigated with cold cup biopsies from the bladder and transurethral loop biopsies from the bladder neck to the verumontanum. The prostate and bladder neck were submitted to sagittal whole-mount pathological analysis. Results. The incidence of TCC in the prostatic urethra and prostate in the cystoprostatectomy specimen was 29% (50/175 patients). Age, previous bacillus Calmette-Gueacuterin treatment, carcinoma in situ (Cis) in the cold cup mapping biopsies and tumour grade were not associated with the risk of TCC in the prostatic urethra/prostate. Cis, multifocal Cis (≥2 locations) and tumour location in the trigone were significantly more common in cystectomy specimens with TCC in the prostatic urethra and prostate: 21/50 (42%) vs 32/125 (26%), p=0.045; 20/50 (40%) vs 27/125 (22%), p=0.023; and 20/50 (40%) vs 26/125 (21%), p=0.01, respectively. Preoperative resectional biopsies from the prostatic urethra in the 154 patients analysed identified 31/47 (66%) of patients with TCC in the prostatic urethra/prostate, with a specificity of 89%. The detection of stromal-invasive and non-stromal involvement was similar: 66% and 65%, respectively. Conclusions. The incidence of TCC in the prostatic urethra and prostate was 29% (50/175) in the cystoprostatectomy specimen. Preoperative biopsies from the prostatic urethra identified 66% of patients with such tumour growth. Our findings suggest that preoperative cold cup mapping biopsies of the bladder for detection of Cis add little extra information with regard to the risk of TCC in the prostatic urethra and prostate.
