Can We Trust TRUS Biopsies? – Summary
Francisco G. La Rosa, MD, Associate Professor in the Department of Pathology at the University of Colorado Anschutz Medical Campus in Denver, evaluates the efficacy of transrectal ultrasonography (TRUS) biopsy and contrasts the technique with transperineal prostate mapping biopsy (TPMB). He describes the development of biopsy techniques, explains how to select a biopsy sample size, and demonstrates why the 360-degree view of the prostate offered by TPMB is advantageous. Dr. La Rosa underscores that sampling should be volume-dependent as the percentage of prostate cancer and high-grade prostatic intraepithelial neoplasia detected using a conventional 8-12 core biopsy declines as the volume of the prostate gland increases. He recommends a scaled approach, beginning with eight biopsy cores for glands up to 15cc and increasing up to 14-20 cores for glands over 50cc. Dr. La Rosa then contrasts TRUS with TPMB, remarking that the latter diagnoses prostate cancer in twice the number of patients and can detect or rule out more aggressive disease. Additionally, two-thirds of men with a previous negative TRUS biopsy were later diagnosed with prostate cancer after undergoing TPMB. Dr. La Rosa concludes that TPMB, which also has lower complication rates, is more reliable than TRUS biopsy.
About The 31st Annual International Prostate Cancer Update:
The International Prostate Cancer Update (IPCU), founded in 1990, is a multi-day CME conference focused on prostate cancer treatment updates with expert, international faculty. It is led by expert physicians and is designed for urologists, medical oncologists, radiation oncologists, and other healthcare professionals involved in the diagnosis and treatment of prostate cancer. Dr. La Rosa delivered this educational activity during the 31st iteration of the meeting in July 2021 in Snowbird, Utah.
