A Fred Hutch study has found that the steroid finasteride, long used to treat prostate enlargement and hair loss, can protect men from developing prostate cancer for up to 16 years. Stock photo by Feature Pics A drug used to treat enlarged prostate or hair loss in men has been shown to have a long-term protective effect against prostate cancer. The study, led by Fred Hutchinson Cancer Research Center biostatistician Dr. Joe Unger and recently published in Journal of the National Cancer Institute, linked data from a large prostate cancer clinical trial conducted by the clinical trial network SWOG with Medicare claims data to determine that the steroid tablet finasteride could protect men from developing the cancer for up to 16 years. The original NCI-funded study, known as the Prostate Cancer Prevention Trial, set out to determine if finasteride (also known as Proscar or Propecia) could prevent prostate cancer in men ages 55 and older. That study, which came to an end in 2003, found finasteride use for seven years reduced a man’s risk of developing prostate cancer by 25 percent and that the protective benefit lasted through that seven-year period, which is how long the study followed participants. Dawn Hershman of Columbia University Medical Center, and Drs. Unger and his colleagues went back to the PCPT cohort of nearly 19,000 healthy men (half of whom were given finasteride and half whom received a placebo) to see if finasteride offered a longer-term benefit. Scott Ramsey and Catherine Tangen of Fred Hutch, then created an algorithm to flag PCPT participants on Medicare who’d been diagnosed with and/or treated for prostate cancer. Twenty five years after it opened for enrollment, the landmark Prostate Cancer Prevention Trial has delivered a final verdict. Finasteride, a common hormone-blocking drug, reduces mens' risk of getting prostate cancer without increasing their risk of dying from the disease. Initial study findings suggested there may be a link between use of the drug and a more lethal form of prostate cancer, but long-term follow-up shows that is not true. Ian Thompson, Jr., principal investigator of SWOG's Prostate Cancer Prevention Trial, or PCPT, will deliver the findings May 19 at the Journal of Urology Lecture at the 2018 Annual American Urological Association Meeting in San Francisco. The meeting is the largest gathering of urologists in the world. "What we can now say is that finasteride not only significantly reduces a man's risk of prostate cancer, it is safe to use based on very long-term follow-up in our study," said Thompson. "In PCPT, we found no increased risk of prostate cancer death in men who took finasteride compared with men who did not. Prostate cancer is the most common cancer diagnosed in American men, and we have found an inexpensive, effective drug that can prevent it. I'm pleased to report that we've answered the questions and closed the book." Thompson is chair of SWOG's genitourinary cancer committee, overseeing development of all urologic cancer studies for the federally-funded cancer clinical trials group, and serves as president of CHRISTUS Santa Rosa Hospital—Medical Center in San Antonio, Texas and as emeritus professor at the University of Texas Health Science Center. He and his team set out to determine whether finasteride, a drug used to treat symptoms of prostate enlargement as well as male pattern baldness, would prevent prostate cancer in men over the age of 55.

If men want to prevent prostate cancer, finasteride is the last thing they should. “Whether the drug actually causes high-grade disease or merely helps find it,”. No — it just prevents you from knowing that you have it, says Patrick C. D., who worries that men taking this drug might be dealing with bad information. Even worse, he adds, taking finasteride might mask the signs of aggressive curable prostate cancer until much later. “Many of my patients have asked me about an article that was in the New York Times,” says Walsh, University Distinguished Service Professor of Urology. The article appeared on the newspaper’s front page on Sunday, June 15, 2008, and the spin on finasteride — that it somehow helps men by preventing them from knowing they have prostate cancer, so they can avoid the potential side effects of treatment — was, in Walsh’s opinion, a disaster. The trouble with finasteride, he says, actually dates back to 2003, when the original article was published in the New England Journal of Medicine. The authors of that article studied 18,000 men who randomly were assigned to receive either 5 mg of finasteride (then used mainly to treat benign enlargement of the prostate; men also use it under the trade name Propecia as a treatment for hair loss) or a placebo. The men in the finasteride group had a 25-percent lower risk of being diagnosed with prostate cancer — but a 68-percent higher risk of being diagnosed with high-grade disease (a Gleason score of 7 to 10; this kind of cancer is generally more difficult to cure).

The findings on nearly 19,000 men also overturn earlier concerns that treatment with finasteride -- the agent in the prostate drug Proscar and the hair-loss drug Propecia -- might promote the development of more virulent prostate cancers in men who contract the disease, researchers said. Finasteride did not affect overall survival rates or survival rates after diagnosis with prostate cancer for men who did and did not receive the drug, said study lead author Dr. Ian Thompson, a urologist and professor at the University of Texas Health Science Center. "If indeed the more high-grade cancers in the men taking finasteride were real, we would expect to find a higher death rate," Thompson said. "The survival of these men was exactly the same."
