Early Diagnosis of Prostate Cancer: A Path Forward – Summary
E. David Crawford, MD, Editor-in-Chief of Grand Rounds in Urology and Professor of Urology at the University of California, San Diego, discusses the challenges of early detection of prostate cancer (PCa), the role of markers in identifying patient risk, and the impact of early detection. He begins by acknowledging the limitations of prostate-specific antigen (PSA) testing alone and notes that the United States Preventive Services Task Force (USPSTF) has raised concerns about PCa early detection, asserting that there is too much overdiagnosis and overtreatment. Because most diagnostic testing is completed by primary care physicians (PCPs) who may not understand the nuances of PSA testing, Dr. Crawford recognizes that PCPs need a simple message from urologists. He states that a PSA of >1.5 ng/ml is a good surrogate for benign prostatic hyperplasia (BPH), prostatitis, and PCa risk, and explains that patients with a PSA of 1.5 ng/ml to 4.0 ng/ml may be in a “danger zone” and require additional testing. Dr. Crawford argues, however, that an abnormal PSA alone should not guide biopsy decisions. Rather, he suggests that prostate cancer markers (PCMs) for patients with elevated PSA can better risk-stratify patients and identify significant cancers, enabling many to avoid biopsy. Dr. Crawford cites the example that using SelectMDx as a risk-stratification tool for biopsy-naive men avoids unnecessary biopsies in 38 percent of patients, minimizes detection of low-grade PCa, and misses only 10 percent of high-grade PCa. Further, using mpMRI in all patients had the highest net benefit, allowing 49% of patients to avoid biopsy and missing only 4.9 percent of high-risk PCa. However, if mpMRI availability is limited or expensive, using mpMRI-only in SelectMDx-positive patients is a good alternative strategy. Dr. Crawford concludes by outlining a diagnostic process whereby doctors may refer a patient to a urologist, repeat PSA testing, and incorporate PCM to better determine the risk of significant cancer as well as the need for biopsy for their patients with an elevated PSA.
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. Crawford delivered this educational activity during the 31st iteration of the meeting in July 2021 in Snowbird, Utah.
