Carcinoma of the bladder in patients less than 40 years old.

The records were reviewed of 22 patients with bladder carcinoma before they were 40 years old to determine whether age alone influenced the course of the disease. There were 19 men and 3 women, reflecting a male predominance of 6 to 1. Of the 9 patients with superficial stage A/O disease 8 are alive 6 months to 28 years after diagnosis, the remaining patient being lost to followup. The other 13 patients with tumors invading muscle are dead, 11 as a direct result of the disease. No evidence was found to substantiate earlier reports that bladder carcinoma in young patients has a more benign behavior.
