5-aminolevulinic acid induced fluorescence cystoscopy can detect more tumour lesions comparing to standard cystoscopy. The goal of our study was to assess the influence of fluorescence cystoscopy used during transurethral resection on the recurrence rate and the length of tumor-free interval in stage Ta, Tl transitional cell carcinoma of the urinary bladder.In prospective randomized study 109 patients with primary or recurrent stage Ta Tl bladder transitional cell carcinoma treated with transurethral resection were enrolled. 17 patients with high grade tumors were evaluated separately. In group A the transurethral resection was performed with standard white light endoscopy, in group B with fluorescence cystoscopy. The patients were followed using standard cystoscopy and urinary cytology. Recurrence free interval was evaluated in whole groups and also for single and multiple and for primary and recurrent tumors separately. The median time to recurrence was 8.05 months in group A and was significantly shorter than 13.54 months in group B (p = 0.04, log-rank test). In separate analyses the median time to recurrence was significantly shorter using fluorescence cystoscopy in multiple (p = 0.004) and in recurrent (p = 0.02) tumors, but not in solitary and primary tumors.5-aminolevulinic acid induced fluorescence cystoscopy used during transurethral resection reduces the early recurrence rate in stage Ta Tl bladder transitional cell carcinoma. |
