Trial Outcomes & Findings for A Phase II, Prospective Study of MRI in the Reclassification of Men Considering Active Surveillance in Prostate Cancer (NCT NCT01858688)

NCT ID: NCT01858688

Last Updated: 2023-05-03

Results Overview

The classification sensitivity of multiparametric endorectal magnetic resonance imaging (MP-erMRI) when compared to the standard of care procedure (transrectal ultrasound-guided (TRUS) re-biopsy) The sensitivity is equivalent to the proportion of patients who were reclassified by MP- erMRI out of the total number of patients who should have been reclassified (given their TRUS re-biopsy result). In other words, it is the proportion of participants reclassified appropriately by MP- erMRI.

PRIMARY outcome

Timeframe: From baseline biopsy to final biopsy, up to 18 months

Population: Population that completed all treatment interventions.

The classification sensitivity of multiparametric endorectal magnetic resonance imaging (MP-erMRI) when compared to the standard of care procedure (transrectal ultrasound-guided (TRUS) re-biopsy) The sensitivity is equivalent to the proportion of patients who were reclassified by MP- erMRI out of the total number of patients who should have been reclassified (given their TRUS re-biopsy result). In other words, it is the proportion of participants reclassified appropriately by MP- erMRI.
