Treating prostate cancer harmful to men over 75




NEW YORK

Doctors should stop routine prostate cancer screening of men over 75 because there is more evidence of harm than benefit, a federal task force advised this week in a new blow to a much scrutinized medical test.

The U.S. Preventive Services Task Force, which made the recommendation, reported finding evidence that the benefits of treatment based on routine screening of this age group “are small to none.” However, treatment often causes “moderate-tosubstantial harms,” including erectile dysfunction and bladder control and bowel problems, the task force said.

The new guidance is the first update by the task force on prostate cancer screening since 2002. The last report on the subject from this panel of experts, which sets the nation’s primary care standards, concluded there was insufficient evidence to recommend prostate screening for men of all ages.

In recent years, there has been a growing debate about the value of the somewhat imprecise PSA test to detect cancer, as well as the value of treating most prostate cancers. A number of experts contend patients are being overtreated.

Most major U.S. medical groups recommend doctors discuss the potential benefits and known harms of prostate screening with their patients and make individual decisions. And most agree such testing shouldn’t occur before age 50.

Earlier this year, a study found that older men who already had early-stage prostate cancer were not taking a big risk by not treating it right away. The vast majority were alive 10 years later without significantly worrying symptoms or had died of other causes.

Prostate cancer treatments are tough, especially on older men. Some doctors instead recommend “watchful waiting” to monitor signs of the disease and treat only if they worsen, but smaller studies give conflicting views of the safety of that approach.

The new guidelines from the Preventive Services Task Force were published in this month’s Annals of Internal Medicine.
