Current beliefs and practice patterns among urologists regarding prostate magnetic resonance imaging and magnetic resonance–targeted biopsy

Abstract

Multiparametric magnetic resonance imaging (MRI) and magnetic resonance (MR) -targeted biopsy have a growing role in the screening and evaluation of prostate cancer. We aim to evaluate the current knowledge, attitude, and practice patterns of urologists regarding this new technique.An anonymous online questionnaire was designed to collect information on urologists' beliefs and use of prostate multiparametric MRI and MR-targeted biopsy. The survey was sent to members of the Society of Urologic Oncology, the Endourological Society, and European Association of Urology. Multivariate logistic regression analysis was performed to determine predictors for use of prostate MRI and MR-targeted biopsy.A total of 302 responses were received (Endourological Society: 175, European Association of Urology: 23, and Society of Urologic Oncology: 104). Most respondents (83.6%) believe MR-targeted biopsy to be moderately to extremely beneficial in the evaluation of prostate cancer. Overall, 85.7% of responders use prostate MRI in their practice, and 63.0% use MR-targeted biopsy. The 2 most common settings for use of MR-targeted biopsy include patients with history of prior negative biopsy result (96.3%) and monitoring patients on active surveillance (72.5%). In those who do not use MR-targeted biopsy, the principal reasons were lack of necessary infrastructure (64.1%) and prohibitive costs (48.1%). On multivariate logistic regression analysis, practice in an academic setting (1.86 [1.02-3.40], P = 0.043) and performing greater than 25 radical prostatectomies per year (2.32 [1.18-4.56], P = 0.015) remained independent predictors for using MR-targeted biopsy.Most respondents of our survey look favorably on use of prostate MRI and MR-targeted biopsy in clinical practice. Over time, reduction in fixed costs and easier access to equipment may lead to further dissemination of this novel and potentially transformative technology.
