[What's new in 2008 in the field of basic and clinical research in bladder cancer?].

Urine cytology was the subject of many communications and its efficacy has been questioned. The interest of fluorescence cystoscopy seems to be obvious either for diagnosis or treatment but its indications remain to be defined. Concerning nonmuscle invading bladder tumors, maintenance treatments and single instillation after transurethral resection of bladder tumors were evaluated. Maintenance treatment with BCG or mitomycin C has to be pursued for a one-year period as soon as it has been proposed. Concerning muscle-invading tumors, laparoscopy was compared to open cystectomy, lymphadenectomy and adjuvant chemotherapy were evaluated. Radical cystectomy is still advocated after neo-adjuvant chemotherapy even when patients are classified cT0 by the end of cycles. Regarding upper urinary tract tumors, there was no difference between open and laparoscopic access for oncologic outcomes.
