Re: Andrea Necchi, Marco Bandini, Giuseppina Calareso, et al. Multiparametric Magnetic Resonance Imaging as a Noninvasive Assessment of Tumor Response to Neoadjuvant Pembrolizumab in Muscle-invasive Bladder Cancer: Preliminary Findings from the PURE-01 Study.

We read with interest the article by Necchi et al [1] regarding the association between bladder multiparametric magnetic resonance imaging (mpMRI) findings after pembrolizumab and the pathological complete response (pCR; pT0). The study sets into the existing extraordinary revolution that is setting the pace of clinical research in bladder tumors. It is a significant article to establish the role of mpMRI to predict the pCR to neoadjuvant immunotherapy.
