Bladder-sparing therapy for muscle-infiltrating bladder cancer

Area of Science:

• Urology
• Oncology

Background:

• Radical cystectomy is the standard treatment for nonmetastatic, muscle-infiltrating bladder cancer.
• Bladder-sparing approaches are being investigated for select patients.

Purpose of the Study:

• To evaluate the efficacy and safety of bladder-sparing protocols for muscle-infiltrating bladder cancer.
• To highlight the need for strict patient selection and close monitoring in bladder-preservation strategies.

Main Methods:

• Review of existing bladder-sparing protocols, including transurethral resection of bladder tumors (TURBT) and partial cystectomy.
• Analysis of combined treatment modalities such as TURBT with chemotherapy and/or radiotherapy.
• Assessment of survival rates and the investigative nature of these approaches.

Main Results:

• Combined protocols using TURBT with chemotherapy, potentially with radiotherapy, offer promising 5-year survival rates of approximately 50% for high-risk patients.
• Bladder-preservation protocols necessitate stringent selection criteria and rigorous follow-up.
• Current evidence suggests these bladder-sparing methods are still considered investigative.

Conclusions:

• While bladder preservation is appealing, current protocols lack randomized trials comparing them to radical cystectomy.
• Further research, including comparative randomized trials, is essential to establish the definitive role of bladder-sparing surgery.
• Carefully selected patients may benefit from bladder-sparing approaches, but their investigative status must be acknowledged.
