title: Invasive bladder cancer treated by radical external radiotherapy.
abstract: Fifty-three consecutive, unselected patients with invasive bladder cancer, Stage T2 to T3, treated by radical radiotherapy have been reviewed. Cystectomy was reserved for patients with significant worsening of disease during treatment, histologically confirmed persistent or recurrent invasive tumour after treatment, or patients with intolerable symptoms due to radiation cystitis. In 64% of our patients a favourable tumour response to radiotherapy was seen, while a further 31% showed disease progression either during or on completion of radiotherapy. Cystectomy was performed on 22% of patients, mainly for radiation cystitis, and was not associated with a significant operative mortality rate. The crude 5-year survival rate was 42%. We conclude that radical radiotherapy is as effective as other forms of treatment for invasive bladder cancer, but that there remains a need to identify those bladder tumours destined to respond poorly to radiotherapy at an earlier stage.
