Conservative management of mucosal prostatic urethral involvement in patients with superficial transitional cell carcinoma of the bladder.

Abstract

Treatment of patients with mucosal prostatic urethral transitional cell carcinoma (TCC) is controversial. In this study, we evaluated the outcome of patients with mucosal prostatic urethral TCC who were managed conservatively. The data of 290 consecutive male patients with superficial TCC of the bladder who were treated at our institution were reviewed. Median age was 63 years and median follow-up was 63 months. Initially, all patients with mucosal PU involvement without evidence of ductal and/or stromal involvement underwent intravesical BCG or Epirubicin therapy. Nineteen patients (6.6%) had mucosal involvement of the prostatic urethra (PU) and concomitant multifocal TCC of the bladder. Of those, 12 patients (12/19, 4.2%) had macroscopic mucosal involvement of the PU, while the other 7 patients (7/19, 2.4%) had microscopic PU tumor. Seven of 12 patients who were treated with BCG and 2 of 7 patients who were treated with Epirubicin achieved complete response. Progression occurred in 3 patients who received BCG and no patients progressed in the Epirubicin group. Prostatic urethral sampling should be considered necessary in intermediate and high risk patients with superficial TCC of the bladder. Intravesical therapy, especially with BCG seems to be an effective treatment alternative in the management of mucosal PU involvement.
