Grade Reclassification Articles

To evaluate the association between apparent diffusion coefficient (ADC) on initial multiparametric MRI (mpMRI) and biopsy grade reclassification (GR) to Grade Group (GG) ≥ 2 prostate cancer (PCa) in men on active surveillance (AS) with GG 1 PCa.

To assess if the adoption of multiparametric magnetic resonance imaging (mpMRI) in active surveillance (AS) has improved the identification of occult higher grade prostate cancer (PCa).

We retrospectively identified men from the Johns Hopkins AS registry enrolled since 2013 (year of mpMRI adoption) with Grade Group (GG) 1 PCa and underwent a single mpMRI.
