Blue light could spot bladder tumors white light misses
NCT ID NCT02660645
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This registry study is gathering information on how well blue light cystoscopy with Cysview detects bladder cancer compared to standard white light cystoscopy. About 4400 adults with suspected or known non-muscle invasive bladder cancer will take part. The goal is to see if the blue light technique finds more tumors and helps guide more complete removal.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Hexaminolevulinate hydrochloride (Cysview) instilled in the bladder, used with a blue light cystoscopy device
- What this could lead to
- If successful, this could confirm that blue light cystoscopy with Cysview finds more bladder tumors than standard white light cystoscopy, leading to better detection and treatment.
- What could go wrong
- This is an observational registry, not a controlled trial, so results may not prove cause and effect. False positives could lead to unnecessary biopsies.
