Comparing blue light and white light methods for bladder cancer surgery

Outcomes of High-risk Non-muscle Invasive Bladder Cancer Treated With Blue Light Resection

Phase 3 Interventional Johns Hopkins University · NCT06525571

This study is testing whether using blue light during bladder cancer surgery can help patients with high-risk non-muscle invasive bladder cancer have better outcomes than using regular white light.

What this trial studies

This clinical trial aims to compare the effectiveness of blue light cystoscopy (BLC) versus white light cystoscopy (WLC) in patients with high-risk non-muscle invasive bladder cancer (NMIBC) undergoing transurethral resection of bladder tumor (TURBT). Patients will be randomly assigned to receive either BLC or WLC, and the study will evaluate outcomes such as the reduction in minimal residual disease (MRD) burden and recurrence-free survival at 12 and 24 months. The trial utilizes advanced imaging techniques and urine next-generation sequencing to assess treatment efficacy and disease recurrence.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with high-risk non-muscle invasive bladder cancer who are undergoing TURBT.

Not a fit: Patients with variant histology, muscle-invasive bladder cancer, or active urinary tract infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes and reduced recurrence rates for patients with bladder cancer.

How similar studies have performed: Previous studies have shown promising results with blue light cystoscopy, indicating potential advantages over traditional methods.
