CHICAGO – Satisfaction ratings for virtual outpatient visits for pediatric orthopedic patients were similar to those for in-person office visits across most categories in an analysis of postencounter surveys completed by patients at the Cleveland Clinic.

Satisfaction ratings for both virtual and office visits were consistently higher than 85% across all measured parameters, according to the data presented at the annual meeting of the American Academy of Orthopaedic Surgeons.

Ahmed Emara, MD, a clinical research fellow in adult joint reconstruction at the Cleveland Clinic, led the study, which included data from all patients or guardians at the clinic who experienced such visits from March 2020 to March 2021.

A total of 1,686 responses were received, of which 226 (13.4%) involved virtual visits and 1,460 (86.6%) involved in-office visits. The primary endpoint was a patient-reported satisfaction score of good or excellent.

Analysis included ratings for access, care provider, telemedicine technology, and overall assessment/perception of satisfaction.
 

Target areas for improvement

In some areas, the virtual visits were less satisfactory than the in-office visits.

Patients had lower odds of reporting good/excellent satisfaction regarding their ability to schedule at a particularly convenient time (odds ratio, 0.1; 95% confidence interval, 0.08-0.18; P < .001). The study authors said scheduling more virtual time slots may help increase satisfaction in that area.

Satisfaction was also lower than with in-office visits with respect to providers’ explanations of patients’ conditions (OR, 0.4; 95% CI, 0.17-0.91; P = .03). Providers may need to find ways to better provide educational material in addition to the virtual consultation, the authors wrote.
 

No significant differences in categories of satisfaction

The researchers accounted for age, sex, traumatic etiology, and anatomic location of the complaint in multivariate regression analysis and found no significant differences between the two types of visits in the odds of getting a good/excellent rating for the following areas: patient inclusion in treatment decision (P = .562), discussion of proposed treatment (P = .222), concern by the provider (P = .189), degree of care for the patient as a person (P = .208), adequacy of teamwork in care provision (P = .053), likelihood of recommending the practice to others (P = .108), ease of receiving care at a particular practice (P = .109), ease of contacting the clinic (P = .177), and likelihood of recommending a particular provider (P = .218).

Anna Dimitriovna Vergun, MD, a pediatric orthopedist at the University of North Carolina at Chapel Hill, who was not involved in the study, said in an interview she had been conducting virtual visits even before the pandemic, when she worked for several years at a Shriner’s children’s hospital in Los Angeles, before coming to UNC. The virtual visits were necessary because the hospital offered charity care and covered an area that included several states.

She said that during the height of the pandemic, 80% of her visits at UNC were virtual; it is down to about 5% now.

Some consultations don’t need physical visits at all, Dr. Vergun noted. For example, UNC is starting a clinic for prenatal counseling in cases in which ultrasound detects a limb deformity. Without a virtual option, she said, pregnant mothers in all parts of the state may have to drive long distances when no physical exam is necessary.

And sometimes, a visit simply involves checking in with families to see whether pain is being controlled, which is done well virtually.

“Those are particularly useful for telemedicine,” Dr. Vergun said. “There’s a lot of space for this to be useful. You sometimes don’t realize it until you start doing it and getting feedback from the families that they like it.”

Other exams may be better suited to office visits, she said. These include spine and hip exams and exams in which providers need to check reflexes.

She said she sees many cases of club feet, for which an in-person exam is needed to determine flexibility.
 

Expert says virtual misses nuances

Ryan Fitzgerald, MD, an orthopedic expert with Children’s Orthopaedic and Scoliosis Surgery Associates in St. Petersburg, Fla., who also was not involved in the study, said in an interview he doesn’t offer the virtual option now because he thinks those visits usually miss too much.

COSSA is a private practice that provides orthopedic services for Johns Hopkins All Children’s Hospital.

“I think physicians’ perspective versus the families’ perspective may be quite a bit different,” he said.

While families like the convenience, “a lot of what we do is watching the patient walk, looking at their hip range of motion, and virtually, that’s a really difficult thing to do,” he said.

You can instruct a family on how to turn a camera on the patient, but “it doesn’t always translate,” he said.

He said virtual visits also highlight disparities in access, because many families don’t own the hardware needed for such visits, and internet connections can be spotty or images pixelated.

Dr. Fitzgerald said virtual visits were helpful during the pandemic and would be beneficial for yearly checkups “if you know [the patient] well and it’s a fairly run-of-the-mill thing.”

However, he said, “everything we do is about human interaction, and I think that’s a downfall of the virtual platform right now. While it is helpful in situations like COVID and where it is a very basic follow-up, it still has a ways to go.”

CHICAGO – Access to medical cannabis (MC) cut opioid prescriptions for patients with chronic noncancer back pain and patients with osteoarthritis, according to preliminary data presented at the annual meeting of the American Academy of Orthopaedic Surgeons.

For those with chronic back pain, the average morphine milligram equivalents (MME) per day dropped from 15.1 to 11.0 (n = 186; P < .01). More than one-third of the patients (38.7%) stopped taking morphine after they filled prescriptions for medical cannabis.

Opioid prescriptions were filled 6 months before access to MC and then were compared with 6 months after access to MC.

In analyzing subgroups, the researchers found that patients who started at less than 15 MME/day and more than 15 MME/day showed significant decreases after filling the MC prescription.

Almost half (48.5%) of the patients in the group that started at less than 15 MME daily dropped to 0 MME/day, and 13.5% of patients who were getting more than 15 MME/day stopped using opioids.

Data on filled opioid prescriptions were gathered from a Prescription Drug Monitoring Program (PDMP) system for patients diagnosed with chronic musculoskeletal noncancer back pain who were eligible for MC access between February 2018 and July 2019.

Medical cannabis has shown benefit in treating chronic pain, but evidence has been limited on whether it can reduce opioid use, which can lead to substance abuse, addiction, overdose, and death, the researchers noted.

Researchers found that using MC via multiple routes of administration seemed to be important.

Patients who used only a single administration route showed a statistically insignificant decrease in MME/day from 20.0 to 15.1 (n = 68; P = .054), whereas patients who used two or more routes showed a significant decrease from 13.2 to 9.5 (n = 76; P < .01).

“We have many patients who are benefiting from a single route of delivery for chronic orthopedic pain,” Ari Greis, DO, a physical medicine and rehabilitation specialist in Bryn Mawr, Pa., and a coauthor of the MC studies for both back pain and OA, said in an interview. “However, our data shows a greater reduction in opioid consumption in patients using more than one route of delivery.”

He said delivery modes in the studies included vaporized cannabis oil or flower; sublingual tinctures; capsules or tablets; and topical lotions, creams, and salves.

Dr. Greis is the director of the medical cannabis department at Rothman Orthopaedic Institute in Bryn Mawr, and is a senior fellow in the Institute of Emerging Health Professions and the Lambert Center for the Study of Medicinal Cannabis and Hemp, both in Philadelphia.
 

Medical cannabis also reduces opioids for OA

The same team of researchers, using the data from the PDMP system, showed that medical cannabis also helped reduce opioid use for osteoarthritis.

For patients using opioids for OA, there was a significant decrease in average MME/day of prescriptions filled by patients following MC access – from 18.2 to 9.8 (n = 40; P < .05). The average drop in MME/day was 46.3%. The percentage of patients who stopped using opioids was 37.5%. Pain score on a 0-10 visual analog scale decreased significantly from 6.6 (n = 36) to 5.0 (n = 26; P < .01) at 3 months and 5.4 (n = 16; P < .05) at 6 months.

Gary Stewart, MD, an orthopedic surgeon in Morrow, Ga., who was not part of the studies, told this news organization that the studies offer good preliminary data to offer help with the opioid issue.

“I sometimes feel that we, as orthopedic surgeons and physicians in general, are working with one hand behind our back. We’re taking something that is a heroin or morphine derivative and giving it to our patients when we know it has a high risk of building tolerance and addiction. But at the same time, we have no alternative,” he said.

He said it’s important to remember the results from the relatively small study are preliminary and observational. People used different forms and amounts of MC and the data show only that prescriptions were filled, but not whether the cannabis was used. Prospective, controlled studies where opioids go head-to-head with MC are needed, he said.

“Still, this can lead us to more studies to give us an option [apart from] an opioid that we know is highly addictive,” he said.

CHICAGO – Patients undergoing primary reverse shoulder arthroplasty (RSA) for their glenohumeral osteoarthritis had more complications of care and higher hospital costs when they also had a diagnosis of depression, new data show.

The abstract was presented at the annual meeting of the American Academy of Orthopedic Surgeons.

Researchers, led by Keith Diamond, MD, an orthopedic surgeon at Maimonides Medical Center in New York, queried a private payer database looking for patients who had primary RSA for treatment of glenohumeral OA and also had a diagnosis of depressive disorder (DD) from 2010 to 2019. Patients without DD served as the controls.

After the randomized matching with controls at a 1:5 ratio, the study consisted of 28,410 patients: 4,084 in the DD group and 24,326 in the control group.

Researchers found that patients with depression had longer hospital stays (3 vs. 2 days, P = .0007). They also had higher frequency and odds of developing side effects within the period of care (47.4% vs. 14.7%; odds ratio, 2.27; 95% CI, 2.10-2.45,  P < .0001).

Patients with depression also had significantly higher rates of medical complications surrounding the surgery and costs were higher ($19,363 vs. $17,927, P < .0001).

Pneumonia rates were much higher in patients with DD (10% vs. 1.8%; OR, 2.88; P < .0001).

Patients with depression had higher odds of cerebrovascular accident (3.1% vs. 0.7%; OR, 2.69, P < .0001); myocardial infarctions (2% vs. 0.4%; OR, 2.54; P < .0001); acute kidney injuries (11.1% vs. 2.3%; OR, 2.11, P < .0001); surgical site infections (4.4% vs. 2.4%; OR, 1.52, P < .0001); and other complications, the authors wrote.

Dr. Diamond said in an interview that there may be a few potential reasons for the associations.

In regard to the strong association with pneumonia, Dr. Diamond hypothesized, “patients with depression can be shown to have lower respiratory drive. If a patient isn’t motivated to get out of bed, that can lead to decreased inflation of the lungs.”

Acute kidney injury could be linked with depression-related lack of self-care in properly hydrating, he said. Surgical site infections could come from suboptimal hygiene related to managing the cast after surgery, which may be more difficult when patients also struggle with depression.

Asked to comment on Dr. Diamond’s study, Grant Garrigues, MD, an associate professor at Rush University Medical Center, Chicago, and director of upper extremity research, told this news organization the study helps confirm known associations between depression and arthritis.

“We know that people with depression and anxiety feel pain differently,” he said. “It might have to do with your outlook – are you catastrophizing or thinking it’s a minor inconvenience? It’s not that it’s just in your head – you physically feel it differently. That is something we’re certainly attuned to. We want to make sure the mental health part of the picture is optimized as much as possible.”

He added that there is increasing evidence of links between depression and the development of arthritis.

“I’m not saying that everyone with arthritis has depression, but with arthritis being multifactorial, there’s a relatively high incidence of symptomatic arthritis in patients with depression,” Dr. Garrigues said.

“We think it may have something to do with the fight-or-flight hormones in your body that may be revved up if you are living in a stressful environment or are living with a mental health problem. Those will actually change – on a cellular and biochemical basis – some of the things that affect arthritis.”
 

Stronger emphasis on mental health

Dr. Diamond said the field needs more emphasis on perioperative state of mind.  

“As orthopedic surgeons, we are preoccupied with the mechanical, the structural aspects of health care as we try to fix bones, ligaments, and tendons. But I think we need to recognize and explore the connection between the psychiatric and psychological health with our musculoskeletal health.”

He noted that, in the preoperative setting, providers look for hypertension, diabetes, smoking status, and other conditions that could complicate surgical outcomes and said mental health should be a factor in whether a surgery proceeds.

“If someone’s diabetes isn’t controlled you can delay an elective case until their [hemoglobin] A1c is under the recommended limit and you get clearance from their primary care doctor. I think that’s something that should be applied to patients with depressive disorders,” Dr. Diamond said.

This study did not distinguish between patients who were being treated for depression at the time of surgery and those not on treatment. More study related to whether treatment affects depression’s association with RSA outcomes is needed, Dr. Diamond added.

Dr. Garrigues said he talks candidly with patients considering surgery about how they are managing their mental health struggles.

“If they say they haven’t seen their psychiatrist or are off their medications, that’s a nonstarter,” he said.

“Anything outside of the surgery you can optimize, whether it’s mental health, medical, social situations – you want to have all your ducks in a row before you dive into surgery,” Dr. Garrigues said.

He added that patients’ mental health status may even affect the venue for the patient – whether outpatient or inpatient, where they can get more supervision and help in making transitions after surgery.

Dr. Diamond and coauthors and Dr. Garrigues disclosed no relevant financial relationships.

CHICAGO – Patients undergoing primary reverse shoulder arthroplasty (RSA) for their glenohumeral osteoarthritis had more complications of care and higher hospital costs when they also had a diagnosis of depression, new data show.

The abstract was presented at the annual meeting of the American Academy of Orthopedic Surgeons.

Researchers, led by Keith Diamond, MD, an orthopedic surgeon at Maimonides Medical Center in New York, queried a private payer database looking for patients who had primary RSA for treatment of glenohumeral OA and also had a diagnosis of depressive disorder (DD) from 2010 to 2019. Patients without DD served as the controls.

After the randomized matching with controls at a 1:5 ratio, the study consisted of 28,410 patients: 4,084 in the DD group and 24,326 in the control group.

Researchers found that patients with depression had longer hospital stays (3 vs. 2 days, P = .0007). They also had higher frequency and odds of developing side effects within the period of care (47.4% vs. 14.7%; odds ratio, 2.27; 95% CI, 2.10-2.45,  P < .0001).

Patients with depression also had significantly higher rates of medical complications surrounding the surgery and costs were higher ($19,363 vs. $17,927, P < .0001).

Pneumonia rates were much higher in patients with DD (10% vs. 1.8%; OR, 2.88; P < .0001).

Patients with depression had higher odds of cerebrovascular accident (3.1% vs. 0.7%; OR, 2.69, P < .0001); myocardial infarctions (2% vs. 0.4%; OR, 2.54; P < .0001); acute kidney injuries (11.1% vs. 2.3%; OR, 2.11, P < .0001); surgical site infections (4.4% vs. 2.4%; OR, 1.52, P < .0001); and other complications, the authors wrote.

Dr. Diamond said in an interview that there may be a few potential reasons for the associations.

In regard to the strong association with pneumonia, Dr. Diamond hypothesized, “patients with depression can be shown to have lower respiratory drive. If a patient isn’t motivated to get out of bed, that can lead to decreased inflation of the lungs.”

Acute kidney injury could be linked with depression-related lack of self-care in properly hydrating, he said. Surgical site infections could come from suboptimal hygiene related to managing the cast after surgery, which may be more difficult when patients also struggle with depression.

Asked to comment on Dr. Diamond’s study, Grant Garrigues, MD, an associate professor at Rush University Medical Center, Chicago, and director of upper extremity research, told this news organization the study helps confirm known associations between depression and arthritis.

“We know that people with depression and anxiety feel pain differently,” he said. “It might have to do with your outlook – are you catastrophizing or thinking it’s a minor inconvenience? It’s not that it’s just in your head – you physically feel it differently. That is something we’re certainly attuned to. We want to make sure the mental health part of the picture is optimized as much as possible.”

CHICAGO - Posterior-stabilized (PS) bearings used in total knee arthroplasty (TKA) may increase the risk of revision compared with bearings of other design, new data suggest.

That possibility has previously been reported in studies outside the United States, and now an analysis of more than 300,000 cases in the American Joint Replacement Registry (AJRR) suggests it’s the case in the United States as well.

Principal investigator Ryland Kagan, MD, of the department of orthopedic surgery at Oregon Health & Science University in Portland, told this news organization, “What’s unique about our experience in the U.S. is our overall high use of PS implants.”

More than half of TKAs in the United States use the PS bearings; in comparison, in Australia and European countries, PS use is closer to 20%, he said. Because of this disparity, previous studies have not been seen as generalizable to the United States, he said.

Researchers used AJRR data from 2012 to 2019 and identified all primary TKA procedures performed during that period. Cases were linked to supplemental Centers for Medicare & Medicaid Services data to find revision procedures that may not have been included in the AJRR database.

Jamil Kendall, MD, an orthopedic resident at OHSU, was first author on the study. The team evaluated patient demographics, polyethylene characteristics, procedure dates, and cause for revision in the 305,279 cases.

Of those cases in which implant characteristics were reported, 161,486 (52.9%) patients received PS bearings, and 143,793 (47.1%) received minimally stabilized bearings.

The researchers compared three minimally stabilized implants (cruciate retaining [CR], anterior stabilized [AS], or pivot bearing designs) with each other for risk and then compared minimally stabilized options as a group with the PS bearings.

They found no significant differences among the three minimally stabilized options.

But revision risk was higher when they compared the minimally stabilized implants with the PS bearing implants. Use of PS bearings had a hazard ratio of 1.25 (95% confidence interval, 1.2-1.3; P < .0001) for all-cause revision and an HR of 1.18 (95% CI, 1.0-1.4; P = .02) for infection.

Among the patients with minimally stabilized bearings, 1,693 (1.2%) underwent revision for any cause, and 334 (0.2%) underwent revision for infection. For patients with PS bearings, 2,406 (1.5%) underwent revision for any cause, and 446 (0.3%) underwent revision for infection.

Even a small difference significant

Dr. Kagan said, “The difference isn’t dramatic, but when you think of the total number of total knee arthroplasties done, you’re talking about millions of procedures. Even with a small increased risk, you’re going to see a large influence for a population.”

Richard Lynn Illgen, MD, director of the University of Wisconsin-Madison joint replacement program, told this news organization this work identifies a trend, but he pointed out that registry-based studies have important limitations.

“They cannot establish causality,” he said. “There are many potential confounding variables and potential selection biases that could affect the study. Specifically, the study did not control for degree of deformity or medical comorbidities. Although some surgeons routinely use PS designs for all primary TKAs, others use PS designs for patients with more severe deformities. It is possible that PS designs were used more frequently in patients with a greater degree of deformity, and this could introduce a selection bias.”

He added that no data were included to enable stratification of groups according to medical comorbidities.

“It is possible that selection bias exists comparing the relative degree of medical comorbidities between patients in the PS TKA and minimally constrained TKA groups,” Dr. Illgen said.

He said further prospective, randomized studies are needed to eliminate selection bias and to better determine whether the observed pattern of increased risk of revision holds up, compared with the minimally supported versions.

The authors acknowledged those limitations, but Dr. Kagan said the high percentage of PS procedures in the United States helps mitigate potential bias.

Dr. Illgen serves as a consultant and developer for Stryker, is chair of the AAOS AJRR Research Projects Subcommittee, and is a member of the AJRR Steering Committee. Dr. Kagan receives research support from KCI, Ortho Development, and Smith & Nephew, where he is also a paid consultant. Dr. Kendall reports no relevant financial relationships. Another coauthor of the study is a paid consultant for 3M, Heraeus, Immunis, Smith & Nephew, Zimmer Biomet, and Total Joint Orthopedics and has stock or stock options in Joint Development.

CHICAGO - Patients 80 years or older undergoing primary total knee arthroplasty (TKA) have similar odds of complications, compared with 65- to 79-year-old patients, an analysis of more than 1.7 million cases suggests.

Priscilla Varghese, MBA, MS, and an MD candidate at State University of New York, Brooklyn, led the research, presented at the American Academy of Orthopaedic Surgeons 2022 annual meeting.

Ms. Varghese’s team queried a Medicare claims database for the years 2005-2014 and analyzed information from 295,908 octogenarians and 1.4 million control patients aged 65-79 who received TKA.

Study group patients were randomly matched to controls in a 1:5 ratio according to gender and comorbidities, including chronic obstructive pulmonary disease, congestive heart failure, diabetes, peripheral vascular disease, and kidney failure.

Octogenarians were found to have higher incidence and odds of 90-day readmission rates (10.59% vs. 9.35%; odds ratio, 1.15; 95% confidence interval, 1.13-1.16; P < .0001).   

Hospital stays were also longer (3.69 days ± 1.95 vs. 3.23 days ± 1.83; P < .0001), compared with controls.

Reassuring older patients

However, Ms. Varghese told this news organization she was surprised to find that the older group had equal incidence and odds of developing medical complications (1.26% vs. 1.26%; OR, 0.99; 95% CI, 0.96-1.03; P =.99).

“That’s a really important piece of information to have when we are advising 80-year-olds – to be able to say their risk of adverse outcomes is similar to someone who’s 10 years, 15 years younger,” she said. “It’s really reassuring.”

These results offer good news to older patients who might be hesitant to undergo the surgery, and good news in general as life expectancy increases and people stay active long into their later years, forecasting the need for more knee replacements.

The number of total knee replacements is expected to rise dramatically in the United States.

In a 2017 study published in Osteoarthritis Cartilage, the authors write, “the number of TKAs in the U.S., which already has the highest [incidence rate] of knee arthroplasty in the world, is expected to increase 143% by 2050.”

Thomas Fleeter, MD, an orthopedic surgeon practicing in Reston, Virginia, who was not involved in the study, told this news organization this study reinforces that “it’s OK to do knee replacements in elderly people; you just have to pick the right ones.”

He pointed out that the study also showed that the 80-and-older patients don’t have the added risk of loosening their mechanical components after the surgery, likely because they are less inclined than their younger counterparts to follow surgery with strenuous activities.

In a subanalysis, revision rates were also lower for the octogenarians (0.01% vs. 0.02% for controls).

Octogenarians who had TKA were found to have lower incidence and odds (1.6% vs. 1.93%; OR, 0.86; 95% CI, 0.83-0.88, P < .001) of implant-related complications, compared with the younger group.

The increased length of stay would be expected, Dr. Fleeter said, because those 80-plus may need a bit more help getting out of bed and may not have as much support at home.

A total knee replacement can have the substantial benefit of improving octogenarians’ ability to maintain their independence longer by facilitating driving or walking.

“It’s a small and manageable risk if you pick the right patients,” he said.

Demand for TKAs rises as population ages

As patients are living longer and wanting to maintain their mobility and as obesity rates are rising, more older patients will seek total knee replacements, especially since the payoff is high, Ms. Varghese noted.

“People who undergo this operation tend to show remarkable decreases in pain and increases in range of motion,” she said.

This study has the advantage of a more personalized look at risks of TKA because it stratifies age groups.

“The literature tends to look at the elderly population as one big cohort – 65 and older,” Ms. Varghese said. “We were able to provide patients more specific data.”

Ms. Varghese and Dr. Fleeter have disclosed no relevant financial relationships.

In a 2017 study published in Osteoarthritis Cartilage, the authors write, “the number of TKAs in the U.S., which already has the highest [incidence rate] of knee arthroplasty in the world, is expected to increase 143% by 2050.”

Thomas Fleeter, MD, an orthopedic surgeon practicing in Reston, Virginia, who was not involved in the study, told this news organization this study reinforces that “it’s OK to do knee replacements in elderly people; you just have to pick the right ones.”

He pointed out that the study also showed that the 80-and-older patients don’t have the added risk of loosening their mechanical components after the surgery, likely because they are less inclined than their younger counterparts to follow surgery with strenuous activities.

In a subanalysis, revision rates were also lower for the octogenarians (0.01% vs. 0.02% for controls).

Octogenarians who had TKA were found to have lower incidence and odds (1.6% vs. 1.93%; OR, 0.86; 95% CI, 0.83-0.88, P < .001) of implant-related complications, compared with the younger group.

The increased length of stay would be expected, Dr. Fleeter said, because those 80-plus may need a bit more help getting out of bed and may not have as much support at home.

A total knee replacement can have the substantial benefit of improving octogenarians’ ability to maintain their independence longer by facilitating driving or walking.

“It’s a small and manageable risk if you pick the right patients,” he said.

Demand for TKAs rises as population ages

As patients are living longer and wanting to maintain their mobility and as obesity rates are rising, more older patients will seek total knee replacements, especially since the payoff is high, Ms. Varghese noted.

“People who undergo this operation tend to show remarkable decreases in pain and increases in range of motion,” she said.

This study has the advantage of a more personalized look at risks of TKA because it stratifies age groups.

“The literature tends to look at the elderly population as one big cohort – 65 and older,” Ms. Varghese said. “We were able to provide patients more specific data.”

Ms. Varghese and Dr. Fleeter have disclosed no relevant financial relationships.

CHICAGO - Patients 80 years or older undergoing primary total knee arthroplasty (TKA) have similar odds of complications, compared with 65- to 79-year-old patients, an analysis of more than 1.7 million cases suggests.

Priscilla Varghese, MBA, MS, and an MD candidate at State University of New York, Brooklyn, led the research, presented at the American Academy of Orthopaedic Surgeons 2022 annual meeting.

Ms. Varghese’s team queried a Medicare claims database for the years 2005-2014 and analyzed information from 295,908 octogenarians and 1.4 million control patients aged 65-79 who received TKA.

Study group patients were randomly matched to controls in a 1:5 ratio according to gender and comorbidities, including chronic obstructive pulmonary disease, congestive heart failure, diabetes, peripheral vascular disease, and kidney failure.

Octogenarians were found to have higher incidence and odds of 90-day readmission rates (10.59% vs. 9.35%; odds ratio, 1.15; 95% confidence interval, 1.13-1.16; P < .0001).   

Hospital stays were also longer (3.69 days ± 1.95 vs. 3.23 days ± 1.83; P < .0001), compared with controls.

Reassuring older patients

However, Ms. Varghese told this news organization she was surprised to find that the older group had equal incidence and odds of developing medical complications (1.26% vs. 1.26%; OR, 0.99; 95% CI, 0.96-1.03; P =.99).

“That’s a really important piece of information to have when we are advising 80-year-olds – to be able to say their risk of adverse outcomes is similar to someone who’s 10 years, 15 years younger,” she said. “It’s really reassuring.”

These results offer good news to older patients who might be hesitant to undergo the surgery, and good news in general as life expectancy increases and people stay active long into their later years, forecasting the need for more knee replacements.

Bleeding risk after cold snare polypectomy is reduced when direct-acting oral anticoagulants (DOACs) are withheld only on the day of the procedure rather than continuing use of these agents, data from a new study suggest.

Findings of the study, led by Atsushi Morita, MD, of the Digestive Disease Center, Showa Inan General Hospital in Komagane, Japan, were published in Gastrointestinal Endoscopy.
 

This prospective, observational single-center study enrolled two consecutive groups of patients receiving antithrombotic medications who were undergoing cold snare polypectomy of colorectal polyps of 10 mm or less.

All colonoscopies were performed by endoscopists who each perform more than 500 endoscopies a year.

During period 1 of the study (2017 and 2018), DOACs were continued, even on the day of polypectomy (DOAC continued group); during period 2 (2019 and 2020), DOACs were withheld only on the day of the procedure (DOAC withheld group).

The primary outcome was the frequency of delayed bleeding requiring endoscopic treatment within 2 weeks after cold snare polypectomy. Among the secondary outcomes were immediate bleeding and the number of hemostatic clips used.

Clinical features were similar between the two groups. The first group included 204 patients, 34% of whom were female (average age, 75 years); the second group included 264 patients, 34% of whom were female (average age, 74 years). The number of cold snare polypectomies was similar between the groups (47 vs. 66, P = .55), as was the average number of polyps per patient (0.72 vs. 0.70, P = .76).

Delayed bleeding after cold snare polypectomy occurred in 4 out of 47 (8.5%) participants in the continued DOAC group versus 0 out of 66 (0%) participants in the DOAC-withheld group (P < .001). There was similar improvement in immediate postpolypectomy bleeding (secondary outcome) between the two groups.

Immediate bleeding after endoscopy lasting more than 30 seconds occurred about four times as often in continued DOAC group versus the DOAC withheld group (12 out of 47 [25.5%] participants vs. 4 out of 66 [6.1%] participants; P < .008).

Polyps measuring up to 10 mm (excluding tiny hyperplastic polyps in the rectum and distal sigmoid colon), were removed using dedicated cold snares measuring 0.30 mm in diameter.

“This result is consistent with the best practice recommendation of short interruptions of DOACs based on the patient’s creatinine clearance before all polypectomy techniques, including cold snare polypectomy,” the authors wrote.
 

Countries’ guidelines differ

Guidelines from American Society for Gastrointestinal Endoscopy, the authors noted, currently recommend stopping DOACs before polypectomy, including cold snare procedures, and restarting them only after hemostasis has been achieved. Moreover, since there is no way for a clinician to predict polyp size, the U.S. guidelines further recommend holding warfarin for 5 days and DOACs for 2-3 days before colonoscopy.

In contrast to the U.S. guidelines, the Japanese Gastroenterological Endoscopy Society guidelines suggest clinicians withhold DOACs only on the day of the procedure.

“This policy of withholding DOACs only on the day of colonoscopy should be considered for routine clinical practice,” the authors wrote.

Rajesh N. Keswani, MD, associate professor of medicine in gastroenterology and hepatology at Northwestern University, Chicago, said in an interview it is difficult to draw firm conclusions from this paper because of its study design but added the authors “appear to have delineated a preferred method for managing DOACs prior to colonoscopy.”

He further noted that most polyps encountered during colonoscopy are less than 10 mm and can be safely managed with cold snare polypectomy.

“The management of DOACs prior to colonoscopy is variable,” Dr. Keswani said, “but ranges from cessation of DOACs multiple days prior to colonoscopy versus uninterrupted use of DOACs throughout the colonoscopy period.”

“The authors suggest that holding DOACs on the day of colonoscopy is the optimal balance between minimizing thromboembolic risk and postpolypectomy bleeding. While this data will need to be validated in larger samples, this provides some guidance to colonoscopists tasked with managing DOACs prior to colonoscopy,” Dr. Keswani said.

Limitations of the study included the small number of patients who received DOACs, conduction of the study at a single hospital in Japan, and the definition of immediate bleeding, which differs based on study design.

No commercial funding or conflicts of interest were reported. Dr. Keswani is a consultant for Boston Scientific and Neptune Medical and receives research support from Virgo.

Excess weight over a lifetime may play a greater role in a person’s risk for colorectal cancer (CRC) than previously thought, according to new research.

In their paper published online March 17 in JAMA Oncology, the authors liken the cumulative effects of a lifetime with overweight or obesity to the increased risk of cancer the more people smoke over time.

This population-based, case-control study was led by Xiangwei Li, MSc, of the division of clinical epidemiology and aging research at the German Cancer Research Center in Heidelberg.

It looked at height and self-reported weight documented in 10-year increments starting at age 20 years up to the current age for 5,635 people with CRC compared with 4,515 people in a control group.

Odds for colorectal cancer increased substantially over the decades when people carried the excess weight long term compared with participants who remained within the normal weight range during the period.

Coauthor Hermann Brenner, MD, MPH, a colleague in Li’s division at the German Cancer Research Center, said in an interview that a key message in the research is that “overweight and obesity are likely to increase the risk of colorectal cancer more strongly than suggested by previous studies that typically had considered body weight only at a single point of time.”

The researchers used a measure of weighted number of years lived with overweight or obesity (WYOs) determined by multiplying excess body mass index by number of years the person carried the excess weight.

They found a link between WYOs and CRC risk, with adjusted odds ratios (ORs) increasing from 1.25 (95% confidence interval [CI], 1.09-1.44) to 2.54 (95% CI, 2.24-2.89) from the first to the fourth quartile of WYOs, compared with people who stayed within normal weight parameters.

The odds went up substantially the longer the time carrying the excess weight.

“Each SD increment in WYOs was associated with an increase of CRC risk by 55% (adjusted OR, 1.55; 95% CI, 1.46-1.64),” the authors wrote. “This OR was higher than the OR per SD increase of excess body mass index at any single point of time, which ranged from 1.04 (95% CI, 0.93-1.16) to 1.27 (95% CI 1.16-1.39).”

Dr. Brenner said that although this study focused on colorectal cancer, “the same is likely to apply for other cancers and other chronic diseases.”

Prevention of overweight and obesity to reduce burden of cancer and other chronic diseases “should become a public health priority,” he said.
 

Preventing overweight in childhood is important

Overweight and obesity increasingly are starting in childhood, he noted, and may be a lifelong burden.

Therefore, “efforts to prevent their development in childhood, adolescence, and young adulthood are particularly important,” Dr. Brenner said.

The average age of the patients was 68 years in both the CRC and control groups. There were more men than women in both groups: 59.7% were men in the CRC group and 61.1% were men in the control group.

“Our proposed concept of WYOs is comparable to the concept of pack-years in that WYOs can be considered a weighted measure of years lived with the exposure, with weights reflecting the intensity of exposure,” the authors wrote.
 

Study helps confirm what is becoming more clear to researchers

Kimmie Ng, MD, MPH, a professor at Harvard Medical School and oncologist at Dana-Farber Cancer Institute, both in Boston, said in an interview that the study helps confirm what is becoming more clear to researchers.

“We do think that exposures over the life course are the ones that will be most strongly contributing to a risk of colorectal cancer as an adult,” she said. “With obesity, what we think is happening is that it’s setting up this milieu of chronic inflammation and insulin resistance and we know those two factors can lead to higher rates of colorectal cancer development and increased tumor growth.”

She said the ideal, but impractical, way to do the study would be to follow healthy people from childhood and document their weight over a lifetime. In this case-control study, people were asked to recall their weight at different time periods, which is a limitation and could lead to recall bias.

But the study is important, Dr. Ng said, and it adds convincing evidence that addressing the link between excess weight and CRC and chronic diseases should be a public health priority. “With the recent rise in young-onset colorectal cancer since the 1990s there has been a lot of interest in looking at whether obesity is a major contributor to that rising trend,” Dr. Ng noted. “If obesity is truly linked to colorectal cancer, these rising rates of obesity are very worrisome for potentially leading to more colorectal cancers in young adulthood and beyond.“

The study authors and Dr. Ng report no relevant financial relationships.

The new research was funded by the German Research Council, the Interdisciplinary Research Program of the National Center for Tumor Diseases, Germany, and the German Federal Ministry of Education and Research.

Kimmie Ng, MD, MPH, a professor at Harvard Medical School and oncologist at Dana-Farber Cancer Institute, both in Boston, said in an interview that the study helps confirm what is becoming more clear to researchers.

“We do think that exposures over the life course are the ones that will be most strongly contributing to a risk of colorectal cancer as an adult,” she said. “With obesity, what we think is happening is that it’s setting up this milieu of chronic inflammation and insulin resistance and we know those two factors can lead to higher rates of colorectal cancer development and increased tumor growth.”

She said the ideal, but impractical, way to do the study would be to follow healthy people from childhood and document their weight over a lifetime. In this case-control study, people were asked to recall their weight at different time periods, which is a limitation and could lead to recall bias.

But the study is important, Dr. Ng said, and it adds convincing evidence that addressing the link between excess weight and CRC and chronic diseases should be a public health priority. “With the recent rise in young-onset colorectal cancer since the 1990s there has been a lot of interest in looking at whether obesity is a major contributor to that rising trend,” Dr. Ng noted. “If obesity is truly linked to colorectal cancer, these rising rates of obesity are very worrisome for potentially leading to more colorectal cancers in young adulthood and beyond.“

The study authors and Dr. Ng report no relevant financial relationships.

The new research was funded by the German Research Council, the Interdisciplinary Research Program of the National Center for Tumor Diseases, Germany, and the German Federal Ministry of Education and Research.

A population-based developmental surveillance program showed high diagnostic accuracy in identifying autism in a community-based sample of infants, toddlers, and preschoolers, according to new data published online in JAMA Network Open.

Researchers, led by Josephine Barbaro, PhD, of Olga Tennison Autism Research Centre at La Trobe University, Bundoora, Australia, said their findings indicate the benefit of using early autism developmental surveillance from infancy to the preschool period rather than one-time screening.

For the study, maternal and child health nurses in Melbourne were trained to use the Social Attention and Communication Surveillance–Revised (SACS-R) and SACS-Preschool (SACS-PR) tools during well-child checkups at 11-30 months of age and at follow-up (42 months of age). Dr. Barbaro helped develop the SACS tools.

Children identified as being at high likelihood for autism (1-2 years of age: n = 327; 42 months of age: n = 168) and at low likelihood for autism plus concerns (42 months of age: n = 28) were referred by their nurse for diagnostic assessment by the researchers.

Diagnostic accuracy of the SACS-R and SACS-PR was determined by comparing likelihood for autism with children’s diagnostic outcome using clinical judgment based on standard autism assessments.

Researchers included 13,511 children ages 11 months to 42 months. Results indicated the SACS-R with SACS-PR (SACS-R+PR) had very high diagnostic accuracy for early autism detection.

According to the paper, SACS-R showed 83% positive predictive value (95% confidence interval, 0.77-0.87) and 99% estimated negative predictive value (95% CI, 0.01-0.02). Specificity (99.6%; 95% CI, 0.99-1.00) was high, with modest sensitivity (62%; 95% CI, 0.57-0.66). When the SACS-PR 42-month assessment was added, estimated sensitivity grew to 96% (95% CI, 0.94-0.98).

“Its greater accuracy, compared with psychometrics of commonly used autism screening tools when used in community-based samples, suggests that the SACS-R+PR can be used universally for the early identification of autism,” the authors wrote.

According to La Trobe University, the tool is used in 10 other countries around the world – among them China, Singapore, Poland, Japan, New Zealand, Nepal, and Bangladesh.

Early identification is crucial for children on the autism spectrum and their families because it facilitates early diagnosis and can help families get access to supports and services.

About 2% of the world’s population is on the autism spectrum. Some studies report prevalence of 4% or higher, the authors noted.

The authors called attention to a systematic review of universal autism screening in primary care, including the Infant-Toddler Checklist and the Modified Checklist for Autism in Toddlers and various versions. The authors of the review noted that few studies had enough participants to establish population sensitivity, specificity, and positive predictive value. Also, psychometric properties reported were modest and/or wide ranging, putting into question the diagnostic accuracy of the tools.

Dr. Barbaro and colleagues highlighted an advantage the current study offers. “A critical difference in this study was the use of a community-based sample rather than a clinical or high-likelihood sibling sample, which may not be representative of the general population of children on the autism spectrum because child outcomes, cognition, and autism prevalence vary by ascertainment strategy and multiplex or simplex status.”

The authors explained that, in the United States, The U.S. Preventive Services Task Force has said there is not enough evidence to recommend universal autism screening and instead recommends routine general developmental surveillance. The American Academy of Pediatrics recommends developmental surveillance between 9 and 30 months and autism-specific screening at 18 and 24 months because of the benefits of early supports and services.

Karen Pierce, PhD, codirector of the Autism Center of Excellence at University of California, San Diego, said in an interview that she was pleased to see that the researchers were able to identify a high percentage of children on the autism spectrum.

She said, however, that the system proposed in this paper involves a substantial amount of time for training the nurses.

The authors acknowledged that, saying, “there may be instances in which this could be impractical.”

Dr. Pierce said that, in the United States, parent questionnaires are combined with clinical judgment to decide which kids are at risk.

“It doesn’t take very much time to fill out these questionnaires,” she said. “That’s the sticking point. I’m not saying necessarily that it shouldn’t be adopted. It would be very hard, I think, to incorporate into current pediatric practice.”

She said a benefit of the SACS program is more hands-on observation of the child, beyond the parent report, which sometimes can reflect more emotionally how the parent is feeling about the child.

She pointed out it was impressive that the Australian team found virtually no false positives.

The researchers also identified an additional 168 children using the preschool version at 42 months who had actually passed at the earlier checkpoint, using the regular SACS-R.

“This underscores a supercritical point,” Dr. Pierce said. “Just because your child may have gotten screened at 12, 18, 24 months and they pass and everything’s looking great, it doesn’t necessarily mean at some point early in development around age 3 that there [wouldn’t] be some clearer signs of autism.”

She said in her own study, published in JAMA Pediatrics, 24% of their sample tested fine at first but were later identified as having autism.

“It underscores the need for repeat screening,” Dr. Pierce said. “That was a striking finding in this study.”

She also pointed out that the authors talk about the “false dichotomy” between screening and surveillance. “They are saying it doesn’t have to be that way. It can be a combined effort. We can have parents filling out screening tools and we can have more observational sessions with kids during checkups. It doesn’t have to be this rigid line between screening and surveillance. I would completely agree with that.”

Dr. Barbaro reported receiving grants from the Sir Robert Menzies Foundation and the Cooperative Research Centre for Living with Autism (Autism CRC) during the study. Funds are partially distributed to Dr. Barbaro for the background intellectual property. One coauthor reported grants from the Menzies Foundation and Autism CRC during the study. Another coauthor reported receiving salary from Autism CRC during the study. No other disclosures were reported. This work was supported by an Allied Health Sciences start-up grant from the Menzies Foundation and the Cooperative Research Centre for Living with Autism, established and supported under the Australian Government’s Cooperative Research Centres Program.

On the morning of Feb. 24, rheumatologist Olena Garmish woke at 5:50 a.m. from the blasts of rocket fire in Kiev, Ukraine, and saw the explosions through her window

She described that next week to this news organization: air sirens 20 hours a day, fearing death 24 hours a day, and growing food shortages.

Dr. Garmish, executive director of the Association of Rheumatologists of Ukraine, said she continued working at a Kiev hospital until March 4, but then had to leave the country with her children and has traveled to two other countries since. Now she is looking for employment abroad after 22 years as a clinical researcher and practitioner.

“We lost our jobs and rheumatology practice,” she said. Now, she says, she provides online consultations to patients as much as she can.

As air strikes continued Tuesday in Ukraine’s capital city and elsewhere throughout the country, rheumatologists are among citizens forced to upend their personal and professional lives and make the best decisions they can to keep themselves and their families safe.

Roman Yatsyshyn, MD, professor at Ivano-Frankivsk National Medical University in Ivano-Frankivsk, Ukraine, and vice president of the Association of Rheumatologists of Ukraine, told this news organization that many rheumatologists, like Dr. Garmish, have been forced to close their practices and flee the country. The hope is that the moves are temporary, he said.

He said rheumatologists there are having very different experiences depending on their proximity to the shelling.

Dmytro Rekalov, MD, PhD, who has been a practicing rheumatologist for 20 years, said he has had to relocate – he hopes temporarily – to western Ukraine.

He told this news organization that the battles are about 40 km (25 miles) from him.

“I have a small private rheumatology clinic in Zaporizhzhia [in southeastern Ukraine], so if they invade our city, I’ll have to close my clinic and find another place to live and to practice in.” Zaporizhzhia is home to the largest nuclear plant in Europe, a facility that came under attack earlier this month.

Doctors from areas under siege have been forced to move to quieter locations and consult with patients remotely, Dr. Yatsyshyn said.  

“Moreover, all doctors are actively volunteering, helping refugees, and supporting our military at the front,” he said, adding that medications are in short supply.

“We express our sincere gratitude to the world and European medical communities for their help for Ukraine at this time. Medicines and medical devices come to Ukraine from many countries around the world every day,” he said.

Dr. Yatsyshyn said the Ministry of Health of Ukraine is coordinating delivery of medications.

“However, there is still a need for an uninterrupted supply of basic antirheumatic drugs, cytostatics, glucocorticosteroids, analgesics, and nonsteroidal anti-inflammatory drugs. We will be grateful if such help will continue to come from our colleagues,” Dr. Yatsyshyn said.

In most cases, he says, rheumatologists stay in touch with their patients via social media and apps, Skype, and Zoom.

“We have also created professional and patient groups in chat rooms,” he said. “There, we can respond quickly to current issues in different regions. If necessary, we send medicines in case of their absence or danger in certain regions of the country. Rheumatologists have set up a joint group for online counseling and exchange.”

Some rheumatologists have been retrained as emergency physicians, he said. In areas with less military activity, rheumatologists continue to treat patients at their practices. In places where it is relatively calm, rheumatologists consult not only local patients but also migrants from other regions affected by the war, Dr. Yatsyshyn explained.

The Association of Rheumatologists of Ukraine continues its activities, he said.

“We monitor the problems of our colleagues, their relocations, security, and the opportunity to work. In close cooperation with the Ministry of Health, we monitor the provision of necessary medicines to our patients. We are very grateful for the help of our colleagues from European associations, the United States, pharmaceutical companies, medical centers, universities, and volunteer organizations.”

“We have two other big requests to the entire medical and scientific community,” Dr. Yatsyshyn said. “To suspend the membership of all Russian medical communities in European and world associations (including EULAR, EUSTAR, Lupus Academy, ACR, British Society of Rheumatology, and others) with a ban on attending international forums just as almost all sports and art organizations in Europe and the civilized world have done.”

The second request, he said, is “to close the sky over Ukraine to stop killing children, civilians, destroying Ukrainian memories, and to destroy Ukrainians as a nation. We pray for this to all the conscious world.”

EULAR, the European Alliance of Associations for Rheumatology, said in a statement, “EULAR has stood for peace in Europe and globally, and for improving the lives of people with rheumatic and musculoskeletal diseases, for 75 years. We are committed to the tradition of humanity and peace and are deeply concerned about the general situation of the people in Ukraine. We will do our utmost to contribute to alleviate the suffering. To this end we are urgently exploring options together with other biomedical partners. Please also help to support the people in Ukraine, for example by donating to UNHCR (the UN refugee agency) or ICRC (International Committee of the Red Cross).

“Moreover, all doctors are actively volunteering, helping refugees, and supporting our military at the front,” he said, adding that medications are in short supply.

“We express our sincere gratitude to the world and European medical communities for their help for Ukraine at this time. Medicines and medical devices come to Ukraine from many countries around the world every day,” he said.

Dr. Yatsyshyn said the Ministry of Health of Ukraine is coordinating delivery of medications.

“However, there is still a need for an uninterrupted supply of basic antirheumatic drugs, cytostatics, glucocorticosteroids, analgesics, and nonsteroidal anti-inflammatory drugs. We will be grateful if such help will continue to come from our colleagues,” Dr. Yatsyshyn said.

In most cases, he says, rheumatologists stay in touch with their patients via social media and apps, Skype, and Zoom.

“We have also created professional and patient groups in chat rooms,” he said. “There, we can respond quickly to current issues in different regions. If necessary, we send medicines in case of their absence or danger in certain regions of the country. Rheumatologists have set up a joint group for online counseling and exchange.”

Some rheumatologists have been retrained as emergency physicians, he said. In areas with less military activity, rheumatologists continue to treat patients at their practices. In places where it is relatively calm, rheumatologists consult not only local patients but also migrants from other regions affected by the war, Dr. Yatsyshyn explained.

The Association of Rheumatologists of Ukraine continues its activities, he said.

“We monitor the problems of our colleagues, their relocations, security, and the opportunity to work. In close cooperation with the Ministry of Health, we monitor the provision of necessary medicines to our patients. We are very grateful for the help of our colleagues from European associations, the United States, pharmaceutical companies, medical centers, universities, and volunteer organizations.”

“We have two other big requests to the entire medical and scientific community,” Dr. Yatsyshyn said. “To suspend the membership of all Russian medical communities in European and world associations (including EULAR, EUSTAR, Lupus Academy, ACR, British Society of Rheumatology, and others) with a ban on attending international forums just as almost all sports and art organizations in Europe and the civilized world have done.”

The second request, he said, is “to close the sky over Ukraine to stop killing children, civilians, destroying Ukrainian memories, and to destroy Ukrainians as a nation. We pray for this to all the conscious world.”

EULAR, the European Alliance of Associations for Rheumatology, said in a statement, “EULAR has stood for peace in Europe and globally, and for improving the lives of people with rheumatic and musculoskeletal diseases, for 75 years. We are committed to the tradition of humanity and peace and are deeply concerned about the general situation of the people in Ukraine. We will do our utmost to contribute to alleviate the suffering. To this end we are urgently exploring options together with other biomedical partners. Please also help to support the people in Ukraine, for example by donating to UNHCR (the UN refugee agency) or ICRC (International Committee of the Red Cross).

Radiofrequency ablation (RFA) is effective and long lasting in preventing esophageal adenocarcinoma, new data suggest.

Researchers, led by Paul Wolfson, MBBS, from the Wellcome/EPSRC (Engineering and Physical Sciences Research Council) Centre for Interventional & Surgical Sciences, University College London also found that most treatment relapses happen early and can be re-treated successfully.

Findings were published in a final 10-year report from the United Kingdom National Halo Radiofrequency Ablation Registry and in Gastrointestinal Endoscopy. Because RFA has been used in mainstream clinical practice only since 2005, long-term data of more than 5 years has been lacking.

Multiple studies have shown that RFA is effective in preventing esophageal cancer, but data have been lacking on how long RFA is effective in preventing esophageal adenocarcinoma in patients with dysplastic Barrett’s esophagus (BE). A significant number of patients with dysplastic BE do not initially have visible lesions. For instance, the U.S. RFA Patient Registry reported an average 2.7-year follow up of 4,982 patients, but only 1,305 had dysplasia, the authors of the U.K. report note.

“It is well-established that endoscopic treatment of dysplastic BE is initially successful in up to 90% of patients,” the authors wrote. “What is less well understood is how long that benefit lasts and if this contributes to a substantial reduction in progression to cancer.”

Researchers prospectively gathered data from 2,535 patients from 28 U.K. specialist centers who underwent RFA therapy for BE (average length 5.2cm, range 1-20 cm). Among the group, 20% had low-grade dysplasia, 54% had high-grade dysplasia, and 26% had intramucosal carcinoma.

They looked at rates of invasive cancer and analyzed data for 1,175 patients to assess clearance rates of dysplasia (CR-D) and intestinal metaplasia (CR-IM) within 2 years of starting RFA, then looked at relapses and rates of return to CR-D and CR-IM after more therapy.

One year after RFA therapy, the Kaplan Meier (KM) rate of invasive cancer in the 2,535 patients was 0.5%. Ten years after starting treatment, the KM cancer rate was 4.1%, with a crude incidence rate of 0.52 per 100 patient-years. After 2 years of RFA, CR-D was 88% and CR-IM was 62.6%.

At 8 years, the KM relapse rates were 5.9% from CR-D and 18.7% from CR-IM. Most relapses happened in the first 2 years.

“Our study confirms durable reversal of dysplasia and BE with RFA, which reduces cancer risk by more than 90% compared to historical control data of 6-19% per annum,” the authors wrote.

Despite advances in diagnosis and treatment for esophageal adenocarcinoma, there has been only small improvement in 5-year survival over the past 40 years, the authors note. Meanwhile, the incidence of continues to rise in the Western world.
 

Researchers look for minimally invasive solutions

Surgery removing the esophagus and lymph node clearance had been the standard for high-grade dysplasia, the authors wrote. It is still the intervention of choice for patients with locoregional disease, but it comes with high morbidity and mortality rates.

This has spurred researchers to look for a minimally invasive solution focused on organ preservation to treat early disease and avoid surgical side effects but also to deliver a cure, according to the authors.

Shria Kumar, MD, assistant professor in the Division of Digestive and Liver Diseases at University of Miami Miller School of Medicine, told this publication, “Endoscopic ablation of dysplasia or intramucosal cancer is a mainstay of Barrett’s treatment.”

She noted the importance of the 10-year time period as the initial studies that established ablation evaluated outcomes within 1-3 years, and more recent data shows 5-year favorable outcomes.

Citing a study from the New England Journal of Medicine, Dr. Kumar said, “The present study’s cohort developed cancer at rates similar to one of the earlier U.S.-based cohorts of Barrett’s patients, suggesting that we can draw some parallels.”

She pointed out notable characteristics in the U.K. cohort: “The majority of participants were male and Caucasian; 80% of had high-grade dysplasia or early cancer upon enrollment and long-segment Barrett’s.”

That difference is important when thinking about how this applies to a more diverse U.S. population, she said, or even patients who don’t have high-grade dysplasia or early cancer when they enroll.

“It’s also important to point out are that individuals with low-grade dysplasia were included in this U.K.-based study. There has been evidence that persons in Europe with low-grade dysplasia have higher rates of progression than persons in the U.S. with low-grade dysplasia.”

Dr. Kumar said this may be attributable to differences in the way pathologists practice in the two countries or in endoscopists’ treatment patterns. U.S. guidelines agree that ablation can be used in select persons with low-grade dysplasia, she said, but it’s an area that needs further study.

“Overall, though, this is a really important study of real-time data showing that ablation is impacting cancer rates in a positive way and that in select patients, we can really decrease the risk of invasive cancer by endoscopic eradication therapies,” Dr. Kumar said.

Two coauthors have received grants from Medtronic and Pentax Medical. The other authors have declared no relevant financial relationships. Dr. Kumar reports no relevant financial relationships.
