On his Common Sense Family Doctor blog, Dr. Kenny Lin reflects on the 40-year old “War on Cancer” declared by President Richard Nixon, and on the 20-year old Prostate, Lung, Colorectal, and Ovarian Cancer (PLCO) Screening trial. He writes:
“This massive study, which eventually enrolled more than 150,000 men and women between age 55 and 74, was designed to test the widespread belief that screening and early detection of the most common cancers could improve morbidity and mortality in the long term. Not a few influential voices suggested that the many millions of dollars invested in running the trial might be better spent on programs to increase the use of these obviously-effective tests in clinical practice.
They were wrong. As of this week, the PLCO study is 0-for-2.
Miss #1 occurred in March of 2009 when the PLCO study first reported no mortality benefit from annual PSA testing, a test that a majority of men over 50 undergo routinely.
Miss #2 occurred over the weekend, when the Journal of the American Medical Association published a landmark paper that ended with the following paragraph:
We conclude that annual screening for ovarian cancer as performed in the PLCO trial with simultaneous CA-125 and transvaginal ultrasound does not reduce disease-specific mortality in women at average risk for ovarian cancer but does increase invasive medical procedures and associated harms.
One of the ovarian study authors told Reuters:
“Many people will say, ‘Oh it’s just a blood test, oh it’s just an ultrasound, what’s the harm?'” The harm is you might have unnecessary surgery that could hurt you.”
Reuters reports that the ovarian research team “recorded more than 3,000 cases of false-positives in the screening group, and of those, more than 1,000 women who didn’t end up having ovarian cancer had surgery because of a positive test result. Those surgeries resulted in serious complications, including infection or cardiovascular complications, in 163 women.”

Puleeeeease... this 'game changer' weight loss drug causes more nausea and vomiting than a placebo. Some game, some change. My friend Gary would spank you for using the eighth word medical reporters should never, ever use. @garyschwitzer @thackerpd

A scary @statnews Op-Ed warns that govt attempts to rein in Pharma may cut off access to "life-changing" drugs.
It takes @garyschwitzer to let us know: the author spent 10 years as Pfizer's public-policy chief. https://twitter.com/garyschwitzer/status/1360325022578053123

June 13, 2011 at 1:47 pmSuch a relief that the medical community seems to be wising up to the problem that early detection is not necessarily a good thing and often, does not mean better patient outcomes. A very nuanced approach to care is necessary but I wonder if we are up to the task.

You are responsible for any comments you leave on this site.
This site is primarily a forum for discussion about the quality (or lack thereof) in journalism or other media messages (advertising, marketing, public relations, medical journals, etc.) It is not intended to be a forum for definitive discussions about medicine or science.
We will delete comments that include personal attacks, unfounded allegations, unverified claims, product pitches, profanity or any from anyone who does not list a full name and a functioning email address.

We don”t have sufficient staffing to contact each commenter who left such a message. If you have a question about why your comment was edited or removed, you can email us at feedback@healthnewsreview.org.
There has been a recent burst of attention to troubles with many comments left on science and science news/communication websites. Read “Online science comments: trolls, trash and treasure.”
The authors of the Retraction Watch comments policy urge commenters:
We”re also concerned about anonymous comments. We ask that all commenters leave their full name and provide an actual email address in case we feel we need to contact them. We may delete any comment left by someone who does not leave their name and a legitimate email address.
