Photodynamic Diagnosis and Recurrence
FIG. 27: Florescence cystoscopy has been shown to lower the recurrence rate of bladder cancer in patients with NMI bladder cancer including also a cohort of T1 patients.[29] One randomized prospective study reported that patients who received blue-light fluorescence cystoscopy guided by hexaminolevulinate (Hexvix; Photocure ASA) had a decrease of 20% in relative risk of recurrence.[33] This means that the number needed to treat to prevent one disease recurrence is 11. A follow-up study showed that the rate of radical cystectomy was also decreased in patients who received a PDD diagnosis.[34]
