mpMRI Compared to Diagnostic TURBT in Patients With Suspected Muscle-Invasive Bladder Cancer Objectives
March 21, 2024 updated by: Nataliya Mar, University of California, Irvine
Outcomes With Multi Parametric MRI (mpMRI) Compared to Diagnostic Transurethral Resection of Bladder Tumor (TURBT) in Patients With Suspected Muscle-Invasive Bladder Cancer - a Pilot Study
This is a pilot, single arm, prospective study that aims to validate the accuracy of the VI-RADS score obtained via multi-parametric magnetic resonance imaging (mpMRI) compared to pathologic cancer stage obtained via diagnostic transurethral bladder tumor resection (TURBT) as well as compare the clinical and quality of life outcomes between these diagnostic modalities in patients with suspected muscle-invasive bladder cancer (MIBC).

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Incidence of concordance between VI-RADS score of 4 or 5 (i.e. muscular propria is likely or very likely) on mpMRI and pathologic muscularis propria invasion (i.e. pT2 tumor stage) on diagnostic TURBT.
Time Frame: Up to 1 year
|
VI-RADS is a five-point scoring system developed to standardize imaging and reporting of bladder tumor invasiveness on mpMRI.
It predicts the degree of possible muscular propria invasion ("muscle-invasiveness") of bladder tumors.
Once diagnostic TURBT is performed, the VI-RADS score from mpMRI will be compared to the pathologic tumor (T) stage from a diagnostic TURBT to assess for concordance.

Up to 1 year
