WASHINGTON (AP) - Healthy men shouldn’t get routine prostate cancer screenings, says updated advice from a government panel that found the PSA blood tests do more harm than good.
Despite strenuous protests from urologists, the U.S. Preventive Services Task Force is sticking by a contentious proposal it made last fall. A final guideline published Monday says there’s little if any evidence that PSA testing saves lives _ while too many men suffer impotence, incontinence, heart attacks, occasionally even death from treatment of tiny tumors that never would have killed them.
The guideline isn’t a mandate. The task force stresses that men who want a PSA test still can get one, but only after the doctor explains the uncertainties. That’s in part because the panel found PSA testing hasn’t been studied adequately in black men and those with prostate cancer in the family, who are at highest risk of the disease.
“This is important information for the public and men to have, and they should talk with their doctors about the risks and benefits of prostate cancer screening and make the decision that’s best for them,” said Mark Weber, a spokesman for the Department of Health and Human Services.
The task force advice goes a step further than major health groups including the American Cancer Society, which has long urged that men decide the issue for themselves after being told of PSA’s pros and cons. But it’s not likely to end an annual ritual for many men 50 and older. After all, the same task force has long urged men over 75 to skip PSA screening, and research suggests almost half of them still get tested.
The controversy will end only with development of better tests _ to finally tell which men’s tumors really will threaten their lives, and who will die with prostate cancer rather than from it, said Dr. Virginia Moyer of the Baylor College of Medicine, who heads the task force.
“We have been told for decades to be terrified of cancer and that the only hope is early detection and treatment,” she said. The reality: “You don’t need to detect all cancers.”
“We don’t want this to be the answer,” Moyer added. “We want to screen for the ones that are going to be aggressive, manage those early _ and leave everyone else alone.”
In an editorial published with the guideline in Annals of Internal Medicine, some urologists argue the panel underestimated PSA’s value and overestimated its harms.
“What PSA screening offers the men is a substantial opportunity to avoid dying a particularly unpleasant death from prostate cancer,” said editorial co-author Dr. William Catalona of Northwestern University, who pioneered the testing.
He spoke Monday from a meeting of the American Urological Association, where doctors debated the guideline’s impact. The urology association advises that men be informed of the potential risks and benefits before screening.
But Dr. Otis Brawley, the American Cancer Society’s chief medical officer, welcomed the task force’s recommendation. He hoped it would help deter mass screenings, where men are given free PSAs at shopping malls and sports arenas without being told of the controversy, screenings that Brawley calls big business when health centers profit from the follow-up care.
“The question is, are we actually curing anybody who needs to be cured right now?” Brawley asked.
Too much PSA, or prostate-specific antigen, in the blood only sometimes signals prostate cancer is brewing. It also can mean a benign enlarged prostate or an infection. Only a biopsy can tell. Most men will get prostate cancer if they live long enough. Some 240,000 U.S. men a year are diagnosed with it, most with slow-growing tumors that carry a very low risk of morphing into the kind that can kill.View Entire Story
