Too Many Older Men Are Still Screened for Prostate Cancer

Last summer season, Joe Loree made an appointment to see his urologist. He’d sometimes observed blood in his urine and needed to have that checked out. His physician ordered a prostate-specific antigen, or PSA, check to measure a protein in his blood which may point out prostate most cancers — or a variety of extra benign circumstances.

“It got here again considerably elevated,” mentioned Mr. Loree, 68, an educational designer who lives in Berkeley, Calif. A biopsy discovered a couple of most cancers cells, “a minuscule quantity,” he recalled.

Mr. Loree was at very low threat, however no one likes listening to the c-word. “It’s unsettling to suppose there’s most cancers rising inside me,” he mentioned.

But as a result of his brother and a good friend had each been recognized with prostate most cancers and had undergone aggressive therapy that he most popular to keep away from, Mr. Loree felt comfy with a extra conservative method referred to as lively surveillance.

It sometimes means periodic PSA assessments and biopsies, typically with MRIs and different assessments, to look at for indicators that the most cancers could also be progressing. He hasn’t, so now he can get PSA assessments each six months as an alternative of each three.

Research exhibits {that a} rising proportion of males with low-risk prostate most cancers are opting for lively surveillance, as medical pointers now suggest.

The prognosis used to guide on to aggressive therapy. As just lately as 2010, about 90 p.c of males with low-risk prostate most cancers underwent rapid surgical procedure to take away the prostate gland (a prostatectomy) or acquired radiation therapy, typically with hormone remedy.

But between 2014 and 2021, the proportion of males at low threat of most cancers who selected lively surveillance rose to just about 60 p.c from about 27 p.c, in response to a research utilizing knowledge from the American Urological Association’s nationwide registry.

“Definitely progress however it’s nonetheless not the place we have to be,” mentioned Dr. Matthew Cooperberg, a urologic oncologist on the University of California, San Francisco, and lead creator of the research.

Changing medical follow typically takes a frustratingly very long time. In the research, 40 p.c of males with low-risk prostate most cancers nonetheless had invasive therapy. And approaches differ enormously between urology practices.

The proportion of males below lively surveillance “ranges from 0 p.c to one hundred pc, relying on which urologist you occur to see,” Dr. Cooperberg mentioned. “Which is ridiculous.”

The newest outcomes of a giant British research, just lately revealed within the New England Journal of Medicine, present extra help for surveillance. Researchers adopted greater than 1,600 males with localized prostate most cancers who, from 1999 to 2009, acquired what they referred to as lively monitoring, a prostatectomy or radiation with hormone remedy.

Over an exceptionally lengthy follow-up averaging 15 years, fewer than 3 p.c of the lads, whose common age at prognosis was 62, had died of prostate most cancers. The variations between the three therapy teams weren’t statistically important.

Although the most cancers within the surveillance group was extra more likely to metastasize, it didn’t result in greater mortality. “The advantage of therapy on this inhabitants is simply not obvious,” mentioned Dr. Oliver Sartor, an oncologist on the Mayo Clinic who makes a speciality of prostate most cancers and who wrote an editorial accompanying the research.

“It does not assist folks reside longer,” Dr. Sartor mentioned of the therapy, most likely due to what is called competing mortality, the probability of dying from one thing else first.

Men whose PSA readings and different check outcomes point out higher-risk tumors, or who’ve household histories of prostate most cancers deaths, fall into a distinct class, consultants cautioned.

“The level of screening is to seek out the aggressive tumors — a small minority, however they kill extra males than another most cancers besides lung most cancers,” Dr. Cooperberg mentioned.

But most prostate most cancers grows so slowly, if it grows in any respect, that different sicknesses are more likely to show deadly first, particularly amongst older males. During the British research, one in 5 males died from different causes, predominantly cardiovascular or respiratory ailments and different cancers.

That’s why pointers from the US Preventive Services Task Force and the American College of Physicians suggest in opposition to routine prostate most cancers screening for males over 69 or 70, or for males who’ve lower than a 10- to 15-year life expectancy. (Men ages 55 to 69 are suggested to debate the harms and advantages with well being care suppliers earlier than deciding to be screened.)

Newly revised pointers from the American Urological Association suggest shared decision-making after age 69, considering age, life expectancy, different threat elements and sufferers’ preferences.

“If you reside lengthy sufficient, prostate most cancers is sort of a traditional function of growing older,” Dr. Cooperberg defined. “By the 70s or 80s, half of all males have some most cancers cells of their prostates.”

Most of these tumors are thought-about “indolent,” which means that they do not unfold or trigger bothersome signs.

Nevertheless, about half of males over 70 proceed PSA screening, in response to a brand new research in JAMA Network Open. Although testing declined with age, “they actually should not be getting screened at this price,” mentioned lead creator Sandhya Kalavacherla, a medical pupil on the University of California, San Diego.

Even amongst males over 80, nearly 40 p.c have been nonetheless getting routine PSA assessments. An elevated PSA studying can immediate a cascade of subsequent assessments and coverings, as a result of “‘most cancers’ is an emotionally charged time period,” Dr. Sartor acknowledged. He nonetheless sees sufferers, he mentioned, whose response to very low-risk most cancers is, “I would like it out, now.”

But therapy entails important unwanted effects, which regularly ease after the primary yr or two however might persist and even intensify. The British knowledge confirmed, for occasion, that six months after therapy, urinary leakage requiring pads affected roughly half of the lads who’d had a prostatectomy, in comparison with 5 p.c of those that underwent radiation and 4 p.c of these below lively surveillance.

After six years, 17 p.c of the prostatectomy group nonetheless wanted pads; amongst these below lively surveillance, it was 8 p.c, and 4 p.c within the radiation group.

Similarly, males below lively surveillance have been extra more likely to retain the flexibility to have erections, though all three teams reported decreased sexual operate with age. After 12 years, males within the radiation group have been twice as probably, at 12 p.c, to report fecal leakage as males within the different teams.

The monetary prices of pointless testing and therapy additionally run excessive, as an evaluation of claims from a big Medicare Advantage program demonstrates. The research, just lately revealed in JAMA Network Open, checked out funds for common PSA screening and associated companies for males over 70 with no pre-existing prostate issues.

“The preliminary screening, which is pointless, triggers these follow-up companies, a sequence of occasions catalyzed by nervousness,” mentioned David Kim, a well being economist on the University of Chicago and lead creator of the research. “The additional it progresses, the tougher it’s to cease.”

From 2016 to 2018, every greenback spent on a PSA check on males over 70 generated one other $6 spent on extra PSA assessments, imaging, radiation and surgical procedure.

Extrapolated to conventional Medicare beneficiaries, Medicare may have spent $46 million for PSA assessments for males over 70 and $275 million in follow-up care, Dr. Kim mentioned.

“We want to alter the incentives, how suppliers receives a commission,” he mentioned.

He advised that refusing to reimburse them for procedures that acquired low suggestions from the US Preventive Services Task Force may imply fewer inappropriate PSA assessments and fewer aggressive therapy of their wake.

Some urologists and oncologists have referred to as for a distinct form of shift — in nomenclature. “Why are we even calling it ‘most cancers’ within the first place?” requested Dr. Sartor, who has argued in opposition to utilizing the phrase for small, low-risk tumors within the prostate.

A much less horrifying label — indolent lesions of epithelial origin, or IDLE, was one suggestion — may go away sufferers much less inclined to see check outcomes as deadly portents and extra prepared to fastidiously observe a standard situation which may by no means result in an working room or a radiation middle.
