Background: The transitional cell carcinoma of the bladder is uncommon below the age of 40 years (1%). There is no univocity on the prognosis of such neoplasm. According to some authors such tumours are non invasive low-grade tumours with low recurrence and therefore an improved prognosis. But according to other authors bladder tumours do not have a different progression compared to tumours arising in older patients.
Methods: The authors present their experience on 28 patients, of whom 8 were under 30 years and 29 between 30 and 40 years of age. All patients had transitional carcinoma of the bladder with different grade and stage of tumour. All patients underwent an endoscopic or surgical treatment.
Results and conclusions: The follow-up of these patients show that tumours have a low grade of recurrence (5-10%) and an improved prognosis particularly in patients under 30 years.
