Abstract


Objectives
To conduct a meta-analysis of randomized controlled trials (RCTs) to assess the therapeutic outcome of fluorescence cystoscopy (FC) guided transurethral resection (TUR) in non-muscle invasive bladder cancer (NMIBC).

Materials and Methods
Relevant RCTs were identified from electronic database (MEDLINE, Embase and the Cochrane Library). The proceedings of relevant congress were also searched. The primary parameters were recurrence rate, the time to fist recurrence, recurrence free survival rate (RFS) and progression rate.

Results
12 RCTs including 2258 patients, which were identified for analysis in our study. Our study showed that the FC group have lower recurrence rate than the white light cystoscopy (WLC) group with statistically significant difference (OR: 0.5; p<0.00001). The time of the FC group first recurrence delayed significantly 7.39 weeks than WLC group (MD: 7.39 weeks; p<0.0001). There was a statistically significant difference in favor of FC in RFS at 1 yr (HR: 0.69; p<0.00001) and 2 yrs (HR: 0.65; p=0.0004). However, the FC group cannot significantly reduce the rate of progression into muscle invasive bladder cancer compared with the WLC group (OR: 0.85; p=0.39).

Conclusions
FC guided TUR was demonstrated to be an effective procedure for delaying recurrence of NMIBC. Unfortunately, FC guided TUR could not significantly decrease the rate of progression into muscle invasive bladder cancer.
