Using advanced MRI to improve diagnosis of muscle-invasive bladder cancer

Multi-parametric MRI in Patients Suspected for Muscle Invasive Bladder Cancer: a New Local Staging Paradigm (BladParadigm)

NA · Radboud University Medical Center · NCT05779631

This study is testing whether a new MRI method can improve the diagnosis of muscle-invasive bladder cancer compared to the standard procedure to see which one is better for patients.

What this trial studies

This clinical trial compares two approaches for diagnosing muscle-invasive bladder cancer (MIBC): the standard transurethral resection of bladder tumor (TURBT) and a new method involving multi-parametric MRI (mpMRI) followed by a same-day cystoscopic bladder biopsy. The study aims to evaluate progression-free survival, time to definitive treatment, and cost-effectiveness between these two diagnostic strategies. It is a multicenter randomized controlled trial involving multiple hospitals in the Netherlands.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with clinically suspected muscle-invasive bladder cancer who do not have lymph node or distant metastases.

Not a fit: Patients who are unable or unwilling to undergo mpMRI or are unfit for TURBT or definitive treatment with curative intent may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to earlier and more accurate diagnosis of bladder cancer, potentially improving patient outcomes.

How similar studies have performed: While similar approaches using mpMRI for cancer diagnosis have shown promise, this specific methodology is relatively novel and has not been extensively tested.
