Transitional cell carcinoma involving the prostate.

Transitional cell carcinoma involving the prostate gland was studied in 27 patients. Three different groups were recognised on the basis of the clinical pattern and histological findings. Each group has a different prognosis and merits a different approach to treatment. Thus, stromal involvement of the prostate by transitional cell carcinoma is a sinister finding that requires radical treatment, whereas ductal involvement by either carcinoma in situ or non-invasive papillary tumours can be managed less aggressively. This study emphasises that the present classification for these tumours is unsatisfactory and that adequate histopathological information is essential for their management.
