The patient with T3b transitional cell carcinoma (TCC) of the bladder has traditionally been treated with radical cystectomy and urinary diversion, but initial success with systemic chemotherapy and renewed interest in quality-of-life issues has increased interest in bladder preservation treatments. Unfortunately, despite multiple trials using limited surgical procedures and neoadjuvant or adjuvant chemotherapy, no combined modality has consistently improved survival over the achieved with radical cystectomy alone in patients with T3b disease. Additionally, continent stomal diversions and orthotopic neobladders allow almost normal continence and voiding in both male and female patients, which calls into question the need for bladder preservation. Although no single treatment modality or urinary diversion is right for all patients, a radical cystectomy with continent diversion provides the best chance for survival and allows the best postoperative quality of life. If bladder preservation treatments are used, inclusion in a clinical trial is recommended.
