Decisional Tools to Determine Need for Biopsy and Re-Biopsy in Men with Elevated PSAs – Summary
Guilherme Godoy, MD, MPH, Assistant Professor of Urology and Urology Oncology at Baylor College of Medicine, in Houston, Texas, discusses how and when to use elevated PSA and other markers to determine whether a biopsy is needed. Dr. Godoy cautions that relying solely on an abnormal level for a sensitive biomarker like PSA can lead to false positives and overtreatment, noting that an elevated PSA is an indicator of the prostate but not necessarily of cancer. He reminds physicians to consider the PSA level related to the size of the prostate before jumping ahead to other steps. Dr. Godoy describes how oft-overlooked PSA derivatives in conjunction with family history and other risk factors can be used to individualize risk and personalize assessments for a patient. He then presents an array of current and emerging molecular, genetic, and imaging-based testing options. The 4Kscore assesses the probability of high-risk cancer (Gleason 7 or higher) in the biopsy and informs risk of metastatic disease in 20 years. This test can also indicate risk stratification for mortality. Urine-based tests such as SelectMDx and EPI ExoDx Prostate Intelliscore similarly provide risk stratification for biopsy-naïve men, while tissue-based tests such as ConfirmMDx are useful when a patient has had a previous negative prostate biopsy. He summarizes with a diagram of the clinical integration of MRI and molecular markers illustrating how these testing options should be used.
About The 25th Annual Innovations in Urologic Practice:
Presented by co-chairs Mohit Khera, MD, MBA, MPH, and Michael Coburn, MD, FACS, the Innovations in Urologic Practice conference provides a detailed review and commentary on multiple genitourinary and urologic diseases. Among the featured oncological topics are bladder cancer and immunotherapies, as well as upper tract cancer management, prostate cancer, including state-of-the-art imaging, focal therapy, and MRI. Experts also discuss new tools and techniques for nephrectomy and treating advanced renal cell carcinoma. In terms of general urological approaches, the conference also includes pelvic reconstruction and trauma, men’s health topics like male infertility and sexual dysfunction, and ways to diagnose and treat infections in the urology patient. Dr. Godoy presented this talk at the 2021 conference.

ABOUT THE AUTHOR
Guilherme Godoy, MD, MS, serves as assistant professor of urology at the Baylor College of Medicine (BCM) in Houston, Texas. He joined the faculty of the Scott Department of Urology at BCM in 2012 and has been the chief of the urology service at Ben Taub General Hospital (Harris Health System), since 2017.
Dr. Godoy earned his medical degree from Fundacao Universitaria do ABC in Sao Paulo, Brazil. His training includes an internship and residency in urology at Santa Casa De Sao Paulo in Vila Buarque, Brazil, and a fellowship in urologic oncology at BCM. Dr. Godoy has also completed urologic oncology fellowship training at Vancouver General Hospital, New York University, and Memorial Sloan-Kettering Cancer Center. He earned his MS in clinical investigations at BCM and has remained active in clinical research, translational studies, and clinical trials, mostly focused on prostate, urothelial (upper and lower urinary tract), and testicular cancers.
Dr. Godoy’s expertise includes early diagnosis, minimally invasive approaches (endoscopic and robotic), utilization of molecular and genetic tools for personalized decision-making, management of hereditary cancers, and surgical management of complex/large genitourinary (GU) tumors. His clinical areas of interest include adrenal and kidney tumors, urothelial cancers (upper and lower urinary tract including ureter, renal pelvis, bladder, and urethra), prostate cancer, penile cancer, and testicular and paratesticular cancers. Dr. Godoy also specializes in the utilization of intestinal segments for urinary tract reconstructions, and coordination of multidisciplinary approaches to manage complex intra-abdominal, retroperitoneal, and pelvic tumors. Dr. Godoy is responsible for and moderates the GU Tumor Board Meetings at Baylor St. Luke’s Medical Center as well as the St. Luke’s International GU Tumor Board Meetings.
