Results of a prospective randomized study assessing the efficacy of fluorescent cystoscopy-assisted transurethral resection and single instillation of doxorubicin in patients with non-muscle-invasive bladder cancer

Objectives To assess the efficacy of two treatment options for non-muscle-invasive bladder cancer (NMIBC): (1) transurethral resection (TUR) guided by fluorescence cystoscopy (FC) with the use of 5-aminolevulinic acid (5-ALA) and (2) single early instillation of doxorubicin in a single-center open-label prospective randomized study with a 2 × 2 factorial design.
