OBJECTIVES: • To evaluate in a prospective, randomized study the impact of hexaminolevulinate blue-light cystoscopy (HAL-BLC) on the diagnostic accuracy and treatment changes in cases of non-muscle invasive bladder cancer (NMIBC) compared with standard white-light cystoscopy (WLC). • To compare the long-term recurrence rates in the two study arms. PATIENTS AND METHODS: • In all, 362 patients suspected of NMIBC were included in the trial based on positive urinary cytology and/or ultrasonographic suspicion of bladder tumours and underwent transurethral resection of bladder tumours. • A single postoperative mytomicin-C instillation was performed in all cases, intravesical chemotherapy for intermediate-risk patients and BCG instillations for high-risk cases. • The follow-up protocol consisted of urinary cytology and WLC every 3 months for 2 years. • Only first-time recurrences after the initial diagnosis were considered. RESULTS: • In the 142 patients with NMIBC in the HAL-BLC series, tumour detection rates significantly improved for carcinoma in situ, pTa andoverall cases. • In 35.2% of the cases, additional malignant lesions were found by HAL-BLC and consequently, the recurrence- and progression-risk categories of patients and subsequent treatment improved in 19% of the cases due to fluorescence cystoscopy. • In all, 125 patients in the HAL-BLC group and 114 of theWLC group completed the follow-up. • The recurrence rate at 3 months was lower in the HAL-BLC series (7.2% vs 15.8%) due to fewer 'other site' recurrences when compared with the WLC series (0.8% vs 6.1%). • The 1 and 2 years recurrence rates were significantly decreased in the HAL-BLC group compared with the WLC group (21.6% vs 32.5% and 31.2% vs 45.6%, respectively). CONCLUSIONS: • HAL-BLC was better than WLC for detecting NMIBC cases and improved tumour detection rates. • HAL-BLC significantly modified the postoperative treatment of cases. • The 3 months, 1 and 2 years recurrence rates were significantly improved in the HAL-BLC arm.
