Transitional cell carcinoma in patients under forty years of age

Transitional cell carcinoma of the urinary tract in patients under the age of 40 is often thought to be a milder form than in the older age groups. However, the literature provides little information on this and is contradictory. We report a series which shows that there is a significant recurrence rate, albeit less than in those aged over 40. The tumours were predominantly low grade and low stage and none could be described as aggressive.
