Summary
Brief summary (as posted)
To date, fluorescence and narrow band imaging cystoscopy have been tested in many prospective within patient trials but only as an "add on" procedure. This results in a bias that does not allow to determine the real impact of such innovative technologies on bladder cancer management. Hereby we propose the first prospective randomized trial which compares narrow band imaging trans urethral resection as a stand alone procedure versus white light transurethral resection. The primary end point is to assess the recurrence rate of bladder cancer lesions with each treatment modality. The study is designed to disclose an inferior recurrence rate (estimated 10%) in the group treated by narrow band imaging transurethral resection respect to the control group, treated by standard transurethral resection.

- description
- Patients will be submitted to standard white light transurethral resection and/or cold cup biopsies of all visible lesions known or suspected to be bladder cancer; 6 random cold cup biopsies from healthy mucosa of bladder trigone, anterior, posterior and lateral walls will be taken in case of a second transurethral resection of newly diagnosed high grade non muscle invasive bladder cancer or of recurrent high grade non muscle invasive bladder cancer

- label
- Narrow band imaging transurethral resection
- description
- The system will be switched to narrow band imaging by simply pushing a button. Transurethral resection and/or cold cup biopsies of all visible lesions known or suspected to be bladder cancer will be performed; 6 random cold cup biopsies from healthy mucosa of bladder trigone, anterior, posterior and lateral walls will be taken in case of a second transurethral resection of newly diagnosed high grade non muscle invasive bladder cancer or of recurrent high grade non muscle invasive bladder cancer.
