Urologic Perspective on the Clinical Utility of and Emerging Data on Micro-Ultrasound – Summary
In part 2 of a 2-part series on micro-ultrasound for prostate cancer imaging, Rafael Sanchez-Salas, MD, Associate Professor of Urology at McGill University in Montreal, Quebec, reviews data on micro-ultrasound (microUS) from a urologic perspective, comparing it to MRI in order to evaluate its clinical utility. He explains that there is more and more data suggesting microUS’s superiority to multiparametric (mp)MRI in screening and the benefits of using it in addition to MRI in clinically significant prostate cancer (csPCa). Dr. Sanchez-Salas discusses microUS’s comparable detection rates to mpMRI as shown by a balanced forest plot with ratios ranging between .94 and 1.05 and its ability to help 23% of patients avoid biopsy with no cases of missed csPCa. He then looks at a study testing a proposed protocol for assessing risk based on microUS which showed a much higher sensitivity than mpMRI in microUS of 87.5% vs. 55-61% but lower specificity of 80% vs. 87-88%. Dr. Sanchez-Salas states that there are still several questions to be answered about microUS’s utility on its own, during active surveillance, for focal therapy, and for bladder cancer staging. He concludes with a discussion of the OPTIMUM trial, which will conclude in spring of 2023 and which is meant to provide level-1 evidence regarding the use of microUS in prostate biopsy.

The Virtual Global Summit on Precision Diagnosis and Treatment of Prostate Cancer brings together key international opinion leaders of every clinical subspecialty involved in patient care. This event is an integral part of the AdMeTech Foundation’s Annual Summit, which was established in 2016 and became seminal in shaping the state of the art and future vision for precision care. The goal of this event is three-fold: 1) Educating the key stakeholders; 2) Supporting a sustained cross-disciplinary dialogue and consensus on the best emerging clinical practices and research priorities; and 3) Expediting clinical adoption of promising novel diagnostics and therapeutics.

ABOUT THE AUTHOR
Rafael Sanchez-Salas, MD, is an Associate Professor of Urology in the Department of Surgery at McGill University in Montreal, Quebec. He is a surgeon and clinician-scientist whose primary interest is in minimally-invasive treatments in urological oncology. He is an established leader in the field of focal therapy for the treatment of localized prostate cancer. Dr. Sanchez-Salas earned his medical degree from the Universidad de los Andes in Mérida, Venezuela, and he was valedictorian of the class of 1998. He completed his basic surgical and urological training at Universidad Central de Venezuela in 2005.
He was awarded with scholarships from Confederacion Americana de Urologia and The European Association of Urology to pursue fellowship training in urological oncology and minimally-invasive urological surgery at Memorial Sloan Kettering Cancer Center in the US, Clinica Santa Maria in Chile, and L’Institut Mutualiste Montsouris in France, where, after his training, he joined the faculty in 2008. Dr. Sanchez-Salas has enjoyed a sound international career as a talented surgical proctor and cancer researcher. His current research priorities include focal therapy for prostate cancer and its impact on prostatic micro-environment and outcomes. He chaired the SIU-International Consultation on Urological Disease on image-guided therapy for Prostate and Renal Carcinomas in 2015.
