Vienna is one of the most romantic cities in Europe. It is the home of the Waltz King, Johann Strauss Jr., whose music sends women in gowns and men in tuxes whirling around over 400 balls per year. This City of Beauty is where the snow globe was born, mesmerizing generations of children. Did you know that the oldest operating Ferris wheel in the world is a symbol of Austria’s capital? And chocolate lovers find Vienna’s Sacher Cake simply to die for. No wonder visitors rapidly fall in love with Vienna.
Recently, publication of new research out of Vienna’s University Hospital and its MedUni Department of Urology suggest that clinicians are rapidly falling out of love—not with Vienna, but with the Digital Rectal Exam (DRE). Patients already don’t love it. Being rectally probed by a lubricated, gloved finger has hardly been a favorite screening PCa test for men subjected to it. Untold numbers of men who might otherwise have participated in annual screenings simply stayed away out of embarrassment or discomfort. This has led to a sorry situation for many of them, because early PCa has no symptoms. Therefore, many of these men later ended up diagnosed with advanced disease.
Thankfully, the new Viennese paper offers good news for patients who avoid DRE as part of PCa screening. The study by Matsukawa, et al. (2024) finds that “the screening performance of digital rectal examination for detection of prostate cancer is not particularly impressive, suggesting that it might not be necessary to conduct this examination routinely.”[i] The conclusion is based on an analysis of over 85,000 cases (data integrated from eight previously published studies), a very impressive number!
Historically, in the late 1980s the combination PSA-plus-DRE was accepted for widespread use as the conventional way to screen for PCa. Since then, the value of DRE has been called into question many times. As one example, I recently posted a blog citing a study that showed how the accuracy of multiparametric MRI simply erases the need for the DRE.
A news story explains the significance of the Viennese analysis. “The results suggest that DRE alone or in combination with PSA may not be more effective in the early detection of prostate cancer compared to PSA testing alone. In particular, DRE alone showed a lower cancer detection rate (CDR) compared to the PSA test.” In other words, the authors are suggesting that the use of the DRE for routine screening be discontinued. It is their hope that by doing so, more men will participate in annual PSA tests.
The world of PCa screening is at a crossroads: if not PSA screening, then what? The US Protective Services Task Force currently recommends that given each individual’s PCa risk factors, the blood test’s merits for him be discussed with his doctor. This advice is understandable because in the past, a single suspicious PSA result led many patients down a biopsy-to-treatment pathway that resulted in collateral harms. Not only do these harms impact quality of life, managing them for months and years after biopsy and/or treatment drives healthcare costs way up. We now see that the baby was thrown out with the bath, as trends now show that as more men skip screening, more patients are being diagnosed with later stage disease requiring more aggressive treatments with long term side effects.
Doctors and patients don’t have to go down that road. Instead, let’s turn the corner onto a new PCa detection highway with no DRE: PSA-plus-mpMRI. Not only can this route eliminate a needless biopsy, in the long run it avoids costs of expensive overtreatments, and of managing biopsy and overtreatment side effects! It overcomes the shortsighted objections of those who point to a cost of a single MRI scan after an abnormal PSA test.
In an interview, study co-author Shahrokh Shariat noted how important it is to identify the best early detection method: “The continuous improvement of prostate cancer screening methods remains of paramount importance to protect the health and well-being of men worldwide.”[ii] I believe following a suspicious PSA with an MRI before biopsy already achieves that goal. We should modify the timeless adage about an ounce of prevention. In the case of the Viennese study, it should now be, “An ounce of accurate early detection is worth a pound of overkill.”
