Treatment of invasive grade 3 transitional cell bladder cancer. A retrospective study of 10 years' experience with external irradiation, and preoperative irradiation and cystectomy.

: Three hundred and seventy-four patients with invasive grade 3 bladder cancer treated with either external irradiation or preoperative irradiation and cystectomy were re-evaluated. Cancer-free survival was markedly better for patients who underwent preoperative irradiation and operation than irradiation only, even if a complete clinical response had occurred initially.
