Stephen J. Freedland, MD
Associate Director, Faculty Development Samuel Oschin Comprehensive Cancer Institute
Co-Director, Cancer Genetics and Prevention Program
Director, Center for Integrated Research in Cancer and Lifestyle
Warschaw Robertson Law Families Chair in Prostate Cancer
Cedars-Sinai, Los Angeles
MedicalResearch.com: What is the background for this study? What are the main findings?
Dr. Freedland: PSA is a marker of prostate pathology. While often used to screen for prostate cancer, it is not prostate specific and can be elevated due to inflammation or enlarged prostate or other reasons. Whether it predicts the development of urinary symptoms is not clear. Among men with minimal to no urinary symptoms, we found that the higher the PSA, the greater the risk of future development of urinary symptoms.
MedicalResearch.com: What should clinicians and patients take away from your report?
Dr. Freedland: The readers should know that if a man has an elevated PSA and a negative prostate biopsy, the higher the PSA, the greater the risk of future urinary symptoms. These are men who may need closer follow-up.
MedicalResearch.com: What recommendations do you have for future research as a result of this study?
Dr. Freedland: The main question is “why”. Why does higher PSA mean greater urinary symptoms risk. Is it due to inflammation? Something else? If we know that, we can figure out some of the causes of urinary symptoms and help to prevent them.
MedicalResearch.com: Is there anything else you would like to add?
Dr. Freedland: The overall risk of developing urinary symptoms is modest. Thus, while these men may need closer follow-up, at this stage, treating these men with a 5-alpha reductase inhibitor or other drugs to prevent urinary symptoms is not warranted.
MedicalResearch.com: Thank you for your contribution to the MedicalResearch.com community.
