Bladder Cancer: Long-Term Benefits of Blue Light Cystoscopy and Enhanced Detection with HD Technology Unveiled at AUA 2024
On
The study, known as BRAVO (Bladder Cancer Recurrence Analysis in Veterans and Outcomes), is a retrospective, propensity score matched analysis that evaluated oncologic outcomes following BLC compared to WLC alone in patients from the
626 patients were included in this study, 313 in each study arm (WLC versus BLC). Recurrence and progression data for BRAVO was measured at a 3-year time point. Overall survival follow-up was for 10 years.
Study results include:
- Risk of recurrence was significantly lower following BLC (HR 0.60, 95% CI 0.29-0.61) – 40% reduction in risk of recurrence. This confirms data from multiple RCT studies.
- Patients who underwent BLC had significantly reduced risk of progression (HR 0.51, 95% CI 0.36-0.99) compared to patients who underwent WLC.
- There was improved overall survival among BLC vs. WLC (HR 0.41, 95% CI 0.30-0.72)
- Additionally, in the equal-access setting of the
VA Healthcare System , benefits of BLC were equitably shared between race/gender.

This study confirms the superiority of HAL BLC over WLC in the detection of bladder cancer even if improved WLC using HD 4K equipment is utilized. In particular, additional high-risk difficult to see CIS lesions have been identified in 80% of CIS patients only by HAL BLC. The quality of resection is still a key cornerstone in the treatment of NMIBC of which BLC remains a crucial part despite the further development of WLC imaging.

About Bladder Cancer
Bladder cancer ranks as the 8th most common cancer worldwide – the 5th most common in men – with 1 949 000 prevalent cases (5-year prevalence rate)1a, 614 000 new cases and more than 220 000 deaths in 2022.1b
Approx. 75% of all bladder cancer cases occur in men.1 It has a high recurrence rate with up to 61% in year one and up to 78% over five years.2 Bladder cancer has the highest lifetime treatment costs per patient of all cancers.3
Bladder cancer is a costly, potentially progressive disease for which patients have to undergo multiple cystoscopies due to the high risk of recurrence. There is an urgent need to improve both the diagnosis and the management of bladder cancer for the benefit of patients and healthcare systems alike.
Bladder cancer is classified into two types, non-muscle invasive bladder cancer (NMIBC) and muscle-invasive bladder cancer (MIBC), depending on the depth of invasion in the bladder wall. NMIBC remains in the inner layer of cells lining the bladder. These cancers are the most common (75%) of all BC cases and include the subtypes Ta, carcinoma in situ (CIS) and T1 lesions. In MIBC the cancer has grown into deeper layers of the bladder wall. These cancers, including subtypes T2, T3 and T4, are more likely to spread and are harder to treat.4

About Hexvix®/Cysview® (hexaminolevulinate HCl)
Hexvix/Cysview is a drug that preferentially accumulates in cancer cells in the bladder, making them glow bright pink during Blue Light Cystoscopy (BLC®). BLC with Hexvix/Cysview, compared to standard white light cystoscopy alone, improves the detection of tumors and leads to more complete resection, fewer residual tumors, and better management decisions.
Cysview is the tradename in the
