Enough time had handed for the reason that affected person’s earlier colonoscopy that she met the factors to bear one other, mentioned Steven Itzkowitz, a gastroenterologist on the Icahn School of Medicine at Mount Sinai in New York.
She was in “reasonably good health,” and the dangers of the process — bleeding, response to anesthesia, perforation of her colon — have been pretty low. But she was 85. And she would want to briefly discontinue the blood thinners she took due to the cardiac stents holding her arteries open; doing so may improve the dangers.
Had Itzkowitz and his affected person confronted this resolution 5 years in the past, he might need scheduled the screening “without even thinking about it,” he mentioned. But current analysis has proven once more that the advantages of a repeat colonoscopy are slim after age 75.
Now, he mentioned, “I’m saying to myself, ‘What are we accomplishing here?’”
He’s not the one physician — or affected person — having second ideas. The dangers and advantages of frequent screenings, procedures, and medicines add up in a different way at superior ages, and analysis continues to level out recent examples of some which will turn out to be pointless.
Recently, investigators have taken on questions on frequent pores and skin lesions that in all probability don’t have to be eliminated, a broadly used thyroid medicine that many older sufferers can safely discontinue, and colonoscopies that scale back colon most cancers mortality so barely that the dangers could outweigh the advantages.
Ugly however Probably Harmless
The reddened or tough patches on the pores and skin are referred to as, in doctor-speak, actinic keratoses. Because they outcome from long-term solar publicity, they normally seem on faces, scalps, forearms, and the backs of arms.
Such lesions seem mostly on older sufferers. One massive research of conventional Medicare beneficiaries discovered that over a five-year interval, almost 30% were diagnosed with an actinic keratosis. Then what?
“The vast majority of the time, they’re removed,” mentioned Allison Billi, a dermatologist on the University of Michigan and an creator of a recent commentary on the subject in JAMA Internal Medicine. That sometimes includes cryosurgery (freezing with liquid nitrogen), topical lotions, or laser remedy.
The rationale: The patches may turn out to be cancerous. But “for the average patient with no history of skin cancer, there is less than a 1-in-1,000 chance of it progressing to skin cancer,” Billi mentioned, citing a 2013 meta-analysis. The lesions are way more more likely to disappear on their very own.
“The treatment may be more burdensome than the condition itself,” she added. Removal “is actually extremely painful, both during and after.” It may cause swelling, irritation, and lasting discoloration.
Besides, an actinic keratosis will probably reappear, or new ones will emerge. “This is a chronic condition,” Billi mentioned.
She has proposed energetic surveillance, as a substitute: Primary care docs may observe the lesions yearly for warning indicators like bleeding, ache, or speedy development, which could warrant elimination. But “in many cases, it’s not necessary,” she mentioned. “We don’t always need to do everything we can do.”
She does advocate utilizing sunscreen, nonetheless.

Questionable Treatment
Patients take levothyroxine, one of many world’s most regularly prescription drugs, when their thyroid glands can’t produce adequate thyroid hormone.
With this situation, referred to as hypothyroidism, “people gain weight. They have less energy. Their hair and skin are dry,” defined Jacobijn Gussekloo, a major care physician and researcher at Leiden University Medical Center within the Netherlands. “Everything slows down.”
Doctors additionally more and more prescribe it for a borderline situation referred to as subclinical hypothyroidism, which normally causes no signs however can progress to hypothyroidism.
Most sufferers take the drug for all times — however have they got to? Gussekloo’s staff has discovered that in lots of older adults with subclinical hypothyroidism, hormone levels normalize on their very own.
The researchers have additionally reported that amongst older folks with the situation, levothyroxine had no effect on symptoms and “no apparent benefit.”
Like any drug, it may well additionally trigger hurt. It could work together with different medicines that older sufferers sometimes take. Moreover, “it requires frequent lab tests and follow-ups, more visits and expense,” mentioned Maria Papaleontiou, an endocrinologist on the University of Michigan and an creator of an editorial in JAMA accompanying the most recent Dutch research.
“In high doses, it can cause hyperthyroidism, which can lead to cardiac arrhythmias and bone loss,” she added. Patients taking it even have to regulate their diets and meal schedules.
To decide whether or not some sufferers may cease taking levothyroxine, the Dutch researchers devised a protocol that step by step decreased doses over 30 weeks, with ongoing lab testing and consultations with docs.
After a yr, 1 / 4 of the 370 individuals, throughout 60, had discontinued the drug whereas sustaining wholesome thyroid perform. Most had been on decrease doses to start with.
Patients shouldn’t cease levothyroxine on their very own, Papaleontiou cautioned. Discontinuation requires really fizzling out step by step, with testing and monitoring. Some sufferers will at all times want the drug.
But it seems that “a select group of adults over 60 may not require this treatment lifelong,” Papaleontiou mentioned.
A Screening With Risks
The query of when older sufferers can safely cease screening for colon most cancers has prompted years of debate. The influential U.S. Preventive Services Task Force provides the screening a lukewarm C rating after age 76, calling the profit “small.”
Yet nearly 60% of older sufferers who’ve had earlier colonoscopies and face restricted life expectations (lower than 5 years) are suggested to bear one other screening, a 2023 study discovered.
As a gastroenterologist on the University of California-San Diego, Samir Gupta recurrently encounters this difficulty with older sufferers. “I know they really have a low risk of colon cancer, and I’m putting them through more risk,” he mentioned.
The threat of problems following a colonoscopy rise with age. One research discovered that almost 7% of sufferers over 75 had a hospitalization or emergency room visit inside a month of the process.
Is it price it? Gupta is the lead creator of a new study of just about 92,000 Veterans Affairs sufferers over 75 who had earlier colonoscopies. In about 28%, the process had discovered an adenoma, a sort of polyp that may turn out to be cancerous. Though solely a small fraction do, gastroenterologists usually take away them.
The researchers discovered that after 10 years, veterans with a earlier adenoma have been extra more likely to develop colon most cancers than these with out one, although the speed was extraordinarily low in each teams.
But simply 0.5% — sure, one-half of 1% — of these with a earlier adenoma died of colon most cancers, in contrast with 0.4% of these with out one. “A tiny difference,” Gupta mentioned.
Both teams have been dwarfed by the variety of veterans — nearly half — who died inside the decade of different causes.
“Even if the procedure goes well, you’ll either find nothing or you’ll find something that’s not going to have real impact on your longevity,” mentioned Itzkowitz, an creator of an editorial printed alongside the research.
Yet he has discovered that many sufferers who’ve had polyps eliminated need to proceed colonoscopies.
It is tough to shift established medical norms. Efforts to “deprescribe” drugs can meet with opposition from each sufferers and well being care professionals.
Many older ladies continue having mammograms previous the purpose of documented profit, and older males typically undergo prostate cancer screening past the really helpful age.
Colonoscopies are much less nice, so maybe older sufferers shall be glad to forgo them. “Even with polyps, the chance of dying from colon cancer is so low compared to everything else that can get you,” Itzkowitz mentioned.
So he informed his 85-year-old affected person that she may skip one other colonoscopy. She appeared happy.
