[Urothelial carcinoma in the prostate (author's transl)].

Some 3% of the prostatic carcinomas in the prostatic cancer register at Homburg are urothelial or transitional cell carcinomas. Based on morphologic and clinical findings, 102 cases are divided into two groups: 50 cases with and 52 cases without involvement of the urinary bladder. In each group there is a subgroup where common prostatic carcinoma is combined with a urothelial carcinoma. Adenocarcinoma can precede the urothelial carcinoma by years. The urothelial carcinoma at first grows predominantly intraductally, is resistent to hormone therapy and carries a bad prognosis. Of the 102 cases, 61 died within 2 years.
