Preoperative Intravesical Electromotive Mitomycin-c for Primary Non-muscle Invasive Bladder Cancer

Study Overview
=================
Brief Summary
-----------------
Early single instillation of chemotherapy after TUR is recommended in the European Association of Urology Guidelines. Nevertheless, the procedure is suboptimal for patients with multiple tumors, sometimes is not tolerated and it can results in severe complications. In both laboratory and clinical studies, intravesical electromotive drug administration (EMDA) increases mitomycin-C (MMC) bladder uptake, resulting in an improved clinical efficacy in non-muscle invasive bladder cancer (NMIBC). The investigators will compare the effects of one immediate pre-TUR intravesical EMDA/MMC instillation with one immediate post-TUR intravesical passive diffusion MMC (PD/MMC) instillation and TUR alone in patients with NMIBC. All eligible patients with primary NMIBC will be randomized into 3 groups who will undergo transurethral resection alone (TUR/alone); TUR plus single immediate postoperative instillation (immediately after TUR) of 40 mg PD/MMC with a dwell time of 60 minutes; or single immediate preoperative instillation (immediately before TUR) of 40 mg EMDA/MMC with 20 mA electric current for 30 minutes. Patients with intermediate and high risk NMIBC will undergo adjuvant intravesical therapy. The primary end points will be the recurrence rate and disease-free interval. All clinical analyses will be performed on an intent to treat basis.
