PSA Testing: Down, but not out!


“Abandonment of PSA testing would lead to a large increase in men presenting with advanced prostate cancer and a reversal of the gains made in prostate-cancer mortality over the past three decades,” the doctors said in the statement. Deaths from the disease have declined by more than 30 percent since testing started, they said.

New Prostate Biopsy Tests Improve Results of Traditional Biopsy

Two new tests are now available that screen material from biopsy samples.  One attempts to reduce the possibility of false negatives in a biopsy that had a negative result for cancer.  The ConfirmMDx test essentially increases the range of a biopsy sample, allowing the laboratory to detect cancer from genetic markers in tumors that may not have been directly sampled and otherwise missed.  This can reduce the need to retest in a future biopsy.  From

When a prostate biopsy is performed for appropriate indications, there may be concern that the cancer may have been missed, despite the usual 10-14 core sampling. Tests which can improve the negative predictive value for a 1st time biopsy have clinically significant benefit, thus potentially avoiding unnecessary repeat biopsies,” said Neal Shore, MD, FACS, CPI, Medical Director at the Carolina Urologic Research Center. “ConfirmMDx is a valuable addition to our armamentarium and addresses an unmet need in diagnostic evaluation.  Many men are subjected to unnecessary repeat biopsies, with the attendant morbidity and cost, as a result of an elevated PSA as well as the concern of missing an undetected cancer.  ConfirmMDx assists in the avoidance of unnecessary repeat biopsies.”


The second test, Oncotype DX, uses genetic information on a positive biopsy result to help distinguish aggressive prostate cancer from slow growing tumors.  This may help a patient and physician choose a treatment plan.  From

The results of our study showed that the individual biological information from the Oncotype DX prostate cancer test tripled the number of patients who can more confidently consider active surveillance and avoid unnecessary treatment and its potential side effects. The test also identified a smaller number of patients who, despite seemingly low-risk clinical factors, had more aggressive disease and, would suggest that they consider immediate treatment,” said Peter Carroll, M.D., MPH, professor and chair, Department of Urology, UCSF and principal investigator of this validation study.  “With these new study results, I believe we may be able to significantly increase the use of active surveillance, which has been limited to some extent by the absence of a validated genomic tool to more accurately distinguish low and high risk disease at the time of biopsy.

Prostate Tests: More results

A few months ago, I visited my uroligist again.  My DRE was unchanged from previous visits.  I did report some minor symptoms for the first time.  An extra overnight trip to urinate now and then, for example.  Every once in a while, the flow just aint what it used to be.  He said there’s probably no need for treatment at this point, but if things worsen, I would consider something like Avodart, Proscar or Flomax.  He also said that since my PSA has risen slightly, I should continue monitoring it every 6 months.

On the plus side, I had another PSA test this week, as I was due for a cholesterol lipid panel blood test.  The level was 2.79, well within my range over the last few years.

More Questions about PSA testing and Prostate Surgery

Fear is a powerful motivator to have surgery, once you have a biopsy.  But, with so many unnecessary biopsies done on the basis of PSA testing, perhaps it’s time this whole system is questioned.  According to new research, many men may not benefit at all from testing or surgery, depending on their situation.  If you have read my blog, I think it becomes very clear that prostate biopsies are making a lot of surgeons a lot of money and lead to a lot of unnecessary surgeries, too.  When will we finally get a tool for detection of these cancers that straight out of the 1950s and surgical methods that aren’t nearly as radical with fewer major side effects?

“The real point is that we shouldn’t focus on finding every prostate cancer because, as this study and all the screening studies show, the majority that you find don’t need to be found,’’ said Dr. Thompson, an author of the editorial. “What we should focus our screening on and our testing on are patients who are likely to have more aggressive tumors in which treatment seems to make a difference.”

Prostate-Cancer Test Not Worth Risk, Advisory Panel Says

The PSA prostate-cancer test used by half of U.S. men older than 40 carries more risks than benefits and shouldn’t be used to diagnose the disease, a U.S. panel said, reaffirming its earlier advice.

Scientific studies suggest the number of deaths avoided by screening are “very small” compared with risks from testing or treatment that can include infections, incontinence, erectile dysfunction and death, the U.S. Preventive Services Task Force said in a medical journal today. The 16-doctor panel kept its recommendation from last October after some doctors and patient groups said discouraging the tests would cost lives.


The PSA exam searches for high levels of prostate-specific antigens. In a 2010 survey, 53 percent of American men older than 40 reported taking the test in the prior two years, according to the U.S. Centers for Disease Control and Prevention.

The panel based its recommendations largely on a U.S. study of 77,000 men who were screened and a European review of 182,000. In the U.S., researchers found no evidence the test reduced deaths. The European trial found the exam lowered the mortality rate. The improvement was due solely to results from Sweden and the Netherlands, while patients in five other countries fared no better after testing, the task force said.

New Research on PCA3 and T2-ERG Tests

Good news- more research on non-invasive testing for prostate cancer:

Initial results of a multicenter trial show that 2 biomarkers, PCA3 and T2-ERG, are found at high levels in prostate cancer compared to noncancerous prostate cells and correlate well with 2 indicators of aggressive prostate cancer, tumor volume and Gleason score. This study was conducted by researchers from the Fred Hutchinson Cancer Research Center, Stanford University, and Beth Israel Deaconess Medical Center, among others.


AP: Prostate testing’s dark side: Men who were harmed

Something many of us have suspected for a long time, giving more credence to the purpose of this blog all the way back to the start of my journey a few years ago.  To read about more real life experiences with Prostate Biopsy and other testing, check out the comments in our popular “What to Expect” blog.  Here’s a snippet from an article by the Associated Press:

Terry Dyroff’s PSA blood test led to a prostate biopsy that didn’t find cancer but gave him a life-threatening infection.

In the emergency room several days later, “I didn’t sit, I just laid on the floor, I felt so bad,” said Dyroff, 65, a retired professor from Silver Spring, Md. “I honestly thought I might be dying.”

 Donald Weaver was a healthy 74-year-old Kansas farmer until doctors went looking for prostate cancer. A PSA test led to a biopsy and surgery, then a heart attack, organ failure and a coma. His grief-stricken wife took him off life support.

 “He died of unnecessary preventive medicine,” said his nephew, Dr. Jay Siwek, vice chairman of family medicine at Georgetown University. “Blood tests can kill you.”

 Since Friday, when a task force of independent scientists said routine PSA testing does more harm than good, urologists who make a living treating prostate cancer have rushed to defend the test, as have patients who believe it saved their lives.

 Less visible are men who have been harmed by testing, as Dyroff and Weaver were. The harm is not so much from the test itself but from everything it triggers – biopsies that usually are false alarms, and treatments that leave many men incontinent or impotent for cancers that in most cases were not a threat.
