Oncologic outcomes and survival in pT0 tumors after radical cystectomy in patients without neoadjuvant chemotherapy: results from a large multicentre collaborative study.

Purpose: To assess the postsurgical survival of patients with urothelial carcinoma of the bladder with pT0 tumor at pathologic examination of cystectomy specimens.
