MedicalResearch.com Interview with: Kirsten Bibbins-Domingo, Ph.D., M.D., M.A.S. Lee Goldman, MD, endowed chair in medicine and professor of medicine and of epidemiology and biostatistics University of California, San Francisco Chair of the U.S. Preventive Services Task Force MedicalResearch.com: What is the background for this study? What are the main findings? Response: Prostate cancer is one of the most common cancers to affect men, and the Task Force believes all men should be aware of the benefits and harms of screening for prostate cancer. Prostate cancer screening with PSA testing can help men reduce their chance of dying of prostate cancer or of having metastatic cancer. These are important benefits but occur in a small number of men. There are risks associated with screening, specifically overdiagnosis and overtreatment with surgery and radiation that can have important side effects like impotence and incontinence. Since the release of our 2012 recommendation, new evidence has emerged that increased the Task Force’s confidence in the benefits of screening, which include reducing the risk of metastatic cancer (a cancer that spreads) and reducing the chance of dying from prostate cancer. This draft recommendation also reflects new evidence on the use of active surveillance in men with low-risk prostate cancers that may help mitigate some of the harms in these men by allowing some men with low risk cancer to delay or avoid surgery or radiation. Therefore, in our new 2017 draft recommendation, the Task Force encourages men ages 55 to 69 to make an individual decision about whether to be screened after a conversation with their clinician about the potential benefits and harms. For men age 70 years and older, the potential benefits do not outweigh the harms, and these men should not be screened for prostate cancer. (more…)

MedicalResearch.com Interview with: Dr Ryan Hutchinson MD and Yair Lotan MD Department of Urology University of Texas Southwestern Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: The United States Preventative Services Task Force recommendation against PSA screening generated significant controversy. Research since then has relied heavily on survey data to examine the impact of the recommendation on PSA screening practices. In a hotly charged issue such as this, such data can carry significant bias. We examined a large, whole-institution data in the years before and after the USPSTF recommendations reflecting actual practice and found that the changes in PSA use at our institution, if any, were small. This is more consistent with behavior seen after the vast majority of practice recommendations. (more…)
