BACKGROUND: The benefits of fluorescent light (FL) cystoscopy with 5-aminolevulinic acid (5-ALA) or hexaminolevulinate (HAL) in non-muscle-invasive bladder cancer (NMIBC) have been mentioned in many trials. Meanwhile, several problems need to be addressed such as the rate of residual disease following these procedures.
OBJECTIVE: To assess the effects of FL cystoscopy compared with white light (WL) cystoscopy on the rate of residual Ta, T1, and carcinoma in situ (CIS) tumors, recurrence-free survival (RFS) and progression-free survival (PFS).
METHODS: A search in the databases PubMed, Embase, the Cochrane Library, China National Knowledge Infrastructure (CNKI) and China Biology Medicine (CBM) was undertaken. Studies were included if their outcomes included the residual tumor rate, PFS or RFS. The data was analyzed by REVMAN 5.3 and STATA 14.0.
RESULTS: The residual tumor rate of the FL group was lower than that of the WL group (relative risk [RR] 0.42; 95 % confidence interval [CI] 0.26-0.80; P = 0.007), which was consistent with the residual Ta rate (RR 0.44; 95 % CI 0.28-0.69; P = 0.0004), the residual T1 rate (RR 0.42; 95 % CI 0.21-0.83; P = 0.01) and the residual CIS rate (RR 0.39; 95 % CI 0.19-0.80; P = 0.01). RFS at the 12-month follow-up (RR 1.15; 95 % CI 1.08-1.28; P = 0.0002) and 24-month follow-up (RR 1.26; 95 % CI 1.17-1.35; P < 0.00001) in the FL group was significantly higher than that in the WL group. However, no statistically significant differences were found in PFS at the 12-month follow-up (RR 1.01; 95 % CI 0.99-1.03; P = 0.17) or 24-month follow-up (RR 1.00; 95 % CI 0.97-1.03; P = 0.95).
CONCLUSION: FL cystoscopy was related to a reduced residual tumor rate compared with WL cystoscopy in NMIBC, which was also consistent with the Ta, T1 and residual CIS rates. RFS was higher in patients with FL cystoscopy at the 12- to 24-month follow-up.
