Abstract
Radical cystectomy is the treatment of choice for nonmetastatic, muscle-infiltrating bladder cancer. Several researchers have proposed the use of a bladder-sparing approach in carefully selected patients. Strict selection criteria and close follow-up are needed for bladder-preservation protocols. Although repeated transurethral resection of bladder tumors or partial cystectomy might be offered to high-risk patients, combined protocols with transurethral resection of bladder tumors and chemotherapy, with or without additional radiotherapy, seem to provide the best results, with 5-year survival rates of about 50%. Even if the chance of preserving the bladder is appealing, and despite evidence of some promising results, these protocols should still be considered investigative because, as yet, there are no randomized trials available that compare cystectomy with bladder-sparing surgery.
Key Points
-
Radical cystectomy is still the standard treatment for muscle-infiltrating bladder cancer
-
Bladder-sparing protocols for muscle-infiltrating bladder cancer should be applied in referral centers, with collaboration between urologists, oncologists and radiotherapists
-
Only very few patients are candidates for partial cystectomy, and they must be willing to comply with the strict surveillance required for bladder-sparing treatment
-
Repeated transurethral resection of bladder tumors is only suitable for a small percentage of very high-risk patients
-
A multimodality approach with chemoradiotherapy is probably the best available bladder-sparing option
-
In selected patients, oncological results of bladder sparing may be equivalent to those of radical cystectomy, but it must be clear that the comparison is between different groups
