Intravesical Adjuvant Electromotive Mitomycin-C in Patients With pTa-pT1 and G1-G2 Non-muscle Invasive Bladder Cancer: a Randomized Controlled Trial

In laboratory and clinical studies, intravesical electromotive drug administration increased mitomycin bladder uptake, improving clinical efficacy in high-risk non-muscle invasive urothelial bladder cancer. The investigators' aim was to compare transurethral resection of bladder tumor and adjuvant intravesical electromotive mitomycin with transurethral resection and adjuvant intravesical passive diffusion mitomycin and transurethral resection alone in patients with primary stage pTa-pT1 and grade G1-G2 urothelial bladder cancer Patients will be randomly assigned to: transurethral resection alone, transurethral resection and adjuvant intravesical 40 mg passive diffusion mitomycin dissolved in 50 ml sterile water infused over 60 minutes once a week for 6 weeks, or transurethral resection and adjuvant intravesical 40 mg electromotive mitomycin dissolved in 100 ml sterile water with 23 mA pulsed electric current for 30 minutes once a week for 6 weeks. Patients in the intravesical adjuvant electromotive and passive diffusion mitomycin groups who are disease-free 3 months after induction treatment, will be scheduled to receive monthly intravesical instillation for 10 months, with the same dose and methods of infusion as initial assigned treatment. All patients will be assessed for safety. The investigators' primary endpoints are recurrence rate and disease-free interval. Analyses will be done by intention to treat.

Active Comparator: Transurethral resection alone
Patients underwent urinary cytology, random cold-cup biopsies of the bladder and prostatic urethra-ie, and complete transurethral resection of all bladder tumour visible on endoscopy, ensuring muscle is included in resected samples. Response to treatment will be assessed with cystoscopy, biopsy and urinary cytology at 3-month intervals for 2 years, 6-month intervals for 3 years and yearly thereafter.
Procedure: Trans-urethral resection
Patients underwent urinary cytology of the bladder and upper urinary tract; random cold-cup biopsies of the bladder and prostatic urethra, and complete transurethral resection of all bladder tumour visible on endoscopy, ensuring muscle is included in resected samples.
Active Comparator: Intravesical passive diffusion mitomycin
Patients underwent urinary cytology, random cold-cup biopsies of the bladder and prostatic urethra, and complete transurethral resection of all bladder tumour visible on endoscopy, ensuring muscle is included in resected samples. Patients are scheduled to receive an initial 6 intravesical mitomycin treatments at weekly intervals commencing 2 weeks after endoscopic procedures. Patients are placed on fluid restriction and oral sodium bicarbonate before intravesical mitomycin treatments. Patients who have a complete response to the initial 6 weekly treatments underwent a further 10 monthly instillations. Response to treatment will be assessed with cystoscopy, biopsy and urinary cytology at 3-month intervals for 2 years, 6-month intervals for 3 years and yearly thereafter.

Patients who have a complete response to the initial 6 weekly treatments underwent a further 10 monthly instillations with the same dose and methods of infusion as initial assigned treatment. Intravesical electromotive drug administration is given by a battery-powered generator delivering a controlled electric current that passes between the active intravesical electrode (integrated into a specific transurethral catheter) and dispersive ground electrodes (on skin of the lower abdomen). Operators set active electrode polarity and current intensity on the generator.
