Treatment of infiltrating bladder carcinoma.

One hundred and seventy-five patients with invasive bladder tumours are reviewed. The overall crude survival rate was 30% at 3 years and 23% at 5 years. The 5-year survival rates for T2 and T3 tumours treated by radical radiotherapy were 38% and 28% respectively. Multiple urinary symptoms, obstruction, a large tumour, and poor differentiation were particularly unfavourable features.
