prostate cancer and people profiting from it- is he talking about me?

The Great Prostate Mistake



EACH year some 30 million American men undergo testing for prostate-specific antigen, an enzyme made by the prostate. Approved by the Food and Drug Administration in 1994, the P.S.A. test is the most commonly used tool for detecting prostate cancer.

The test’s popularity has led to a hugely expensive public health disaster. It’s an issue I am painfully familiar with — I discovered P.S.A. in 1970. As Congress searches for ways to cut costs in our health care system, a significant savings could come from changing the way the antigen is used to screen for prostate cancer.

Americans spend an enormous amount testing for prostate cancer. The annual bill for P.S.A. screening is at least $3 billion, with much of it paid for by Medicare and the Veterans Administration.

Prostate cancer may get a lot of press, but consider the numbers: American men have a 16 percent lifetime chance of receiving a diagnosis of prostate cancer, but only a 3 percent chance of dying from it. That’s because the majority of prostate cancers grow slowly. In other words, men lucky enough to reach old age are much more likely to die with prostate cancer than to die of it.

Even then, the test is hardly more effective than a coin toss. As I’ve been trying to make clear for many years now, P.S.A. testing can’t detect prostate cancer and, more important, it can’t distinguish between the two types of prostate cancer — the one that will kill you and the one that won’t.

Instead, the test simply reveals how much of the prostate antigen a man has in his blood. Infections, over-the-counter drugs like ibuprofen, and benign swelling of the prostate can all elevate a man’s P.S.A. levels, but none of these factors signals cancer. Men with low readings might still harbor dangerous cancers, while those with high readings might be completely healthy.

In approving the procedure, the Food and Drug Administration relied heavily on a study that showed testing could detect 3.8 percent of prostate cancers, which was a better rate than the standard method, a digital rectal exam.

Still, 3.8 percent is a small number. Nevertheless, especially in the early days of screening, men with a reading over four nanograms per milliliter were sent for painful prostate biopsies. If the biopsy showed any signs of cancer, the patient was almost always pushed into surgery, intensive radiation or other damaging treatments.

The medical community is slowly turning against P.S.A. screening. Last year, The New England Journal of Medicine published results from the two largest studies of the screening procedure, one in Europe and one in the United States. The results from the American study show that over a period of 7 to 10 years, screening did not reduce the death rate in men 55 and over.

The European study showed a small decline in death rates, but also found that 48 men would need to be treated to save one life. That’s 47 men who, in all likelihood, can no longer function sexually or stay out of the bathroom for long.

Numerous early screening proponents, including Thomas Stamey, a well-known Stanford University urologist, have come out against routine testing; last month, the American Cancer Society urged more caution in using the test. The American College of Preventive Medicine also concluded that there was insufficient evidence to recommend routine screening.

So why is it still used? Because drug companies continue peddling the tests and advocacy groups push “prostate cancer awareness” by encouraging men to get screened. Shamefully, the American Urological Association still recommends screening, while the National Cancer Institute is vague on the issue, stating that the evidence is unclear.

The federal panel empowered to evaluate cancer screening tests, the Preventive Services Task Force, recently recommended against P.S.A. screening for men aged 75 or older. But the group has still not made a recommendation either way for younger men.

Prostate-specific antigen testing does have a place. After treatment for prostate cancer, for instance, a rapidly rising score indicates a return of the disease. And men with a family history of prostate cancer should probably get tested regularly. If their score starts skyrocketing, it could mean cancer.

But these uses are limited. Testing should absolutely not be deployed to screen the entire population of men over the age of 50, the outcome pushed by those who stand to profit.

I never dreamed that my discovery four decades ago would lead to such a profit-driven public health disaster. The medical community must confront reality and stop the inappropriate use of P.S.A. screening. Doing so would save billions of dollars and rescue millions of men from unnecessary, debilitating treatments.

Richard J. Ablin is a research professor of immunobiology and pathology at the University of Arizona College of Medicine and the president of the Robert Benjamin Ablin Foundation for Cancer Research.

Mr Ablin is a “research” professor. The AUA is an organization of M.D.’s that actually talk to, examine, advise and treat patients. For an “ivory tower” professor to comment on the appropriateness of what practicing physicians do or recommend borders on laughable. How is it that I,  a urologist and a prostate cancer patient diagnosed  without symptoms or  an abnormal rectal exam, don’t feel the way the author does? Is it that I am profitting from it? Who do you believe has more credibility in the debate? Go ahead…comment.

  1. This is a tough call but Dr. Ablin did not comment on how following PSA over a period of a year and finding it continues to rise. What is the significance of a constantly rising PSA. What does this mean? Do you just ognore it?


  2. to marky mark… is all about what you can live with. i was diagnosed at age 52 and the biopsy was done not because of symptoms, but because of an elevated PSA and a low free PSA. My final path was similiar to my biopsy report – a small element of gleason’s 7 and my disease was bilateral. I have seen this type of scenario progress to death in my 24 years of practice, i took three months to decide what to do and had the prostate removed. so… you are doing what i did, that can’t be all that wrong. there is a piece of mind element to all this.

    on the rising PSA… we worry about quick changes in PSA, PSA velocity, and a rising PSA and in my opinion this is a significant finding and most usually results in the urologist suggesting a biopsy. by the way, dr. peters you are really on to something with your survey concerning men and women and sexuallity issues. i eagerly await your final results.

    mm… good luck email me anytime , i have indeed been there done that on so many levels…. jm


  3. Many thanks. I had symptoms for a couple of days that resolved but then did my annual blood work. My PSA was 3 (at 52) and I noticed it had been 1.7 a little over two years earlier. I went on Cipro and had it re-tested and it went up, although I was tested right after running a half marathon. I then was diagnosed with prostatitis, and the PSA got down to 2.3, but some firmness was noted by one person and that led to a biopsy. Gleason 7, with it being mostly 3’s, but 5 positive cores–most have 5-10% but one had 90%. There wasn’t much of a debate in the advice I was given and so I accepted it.

    There was an op ed here recently as well which suggested PSA testing leads to surgery that isn’t necessary, but it left out the biopsy. Perhaps some biopsies ought not to be done, but once it’s done I’m not sure how easy it would be to go with active surveillance with results like mine.

    I appreciate your comment and I feel better knowing someone with your expertise made the same call!
