Carcinoma of the bladder - radiotherapy.

Differentiated transitional cell carcinoma responded better to radiotherapy than anaplastic or squamous cell carcinoma. Five year survival was higher in low stage than in high stage carcinoma, and higher in papillary than in solid carcinoma. Tumour control, but also complication rate, increased with higher radiation dose. With the introduction of a two volume irradiation technique, a large tumour dose can be given with a minimum of complications.
