Optimal timing of chemotherapy and cystectomy.

Radical cystectomy with pelvic lymphadenectomy is the standard treatment for muscle-invasive bladder cancer. However, the high recurrence rates and high death rate from metastases after radical cystectomy for locally advanced bladder cancer emphasize the high risk of occult distant disease. To improve patient survival, multimodal therapy whereby chemotherapy and surgery are used in concert with each other is necessary. The preponderance of data suggests that neoadjuvant chemotherapy offers patients a clear - albeit small - survival advantage, whereas the data for adjuvant chemotherapy are less convincing. Currently, trials to improve the results of such neoadjuvant therapy using biologic targets in conjunction with cytotoxic regimens are under way.
