Transitional Cell Carcinoma of the Posterior Urethra in Men: Our Experience

Abstract

We present the experience of the Division of Urology of Mantova Hospital about the primitive carcinoma of the posterior male urethra. This kind of tumor is very rare and there are't great experiences that permit to define a standardize therapy. Material and Methods. Three cases of primary posterior urethral carcinoma who had been treated at our institution between 1999 and 2001 were retrospectively analyzed. The location of the tumor was in 2 cases in the prostatic urethra and in 1 case in the membranosus urethra. The treatment was cistoprostatectomy in 1 case, cistoprostcatectomy associated with penectomy in the case of carcinoma of the membranosus urethra and a prostatectomy in one case of the carcinoma of the prostatic urethra. In 2 cases an adiuvant chemotherapy with cispaltinum was performed while in the third patient a chemiotherapy with gemcitabina was performed at the presentation of a local relapse of tumor. Results. In the case of carcinoma of the prostatic urethra treated with cistoprostatectomy and uretrhectomy and adiuvant chemotherapy there was a good local and distand controll of the cancer with a follow up of 24 months. The patients with carcinoma of the membranosus urethra treated with cistoprostcatectomy associated with penectomy and adiuvant chemiotherapy had a local relapse at 24 months and was treated with radiotherapy. The patient treated with only prostatectomy presented a local relapse at 2 months and distant metastasis at 15 months. After 2 years this patient is still alive but in clinical progression. Conclusions. The most adequate treatment in the cases of posterior urethral cancer seems the major surgical treatment with urethrectomy associated with radical cistectomy. In advanced stages chemotherapy which by necessity must follow the guidelines established for the treatment of other urothelial cell malignancies seems to give good results. The follow-up of these patients has to be very close.
