Large-scale scanning of serum proteins offers a potential method for noninvasive screening and monitoring of patients with nonalcoholic steatohepatitis (NASH), the technique’s developers claim.

By scanning for about 5,000 proteins in nearly 3,000 samples from patients enrolled in studies from the Clinical Research Network in NASH (NASH CRN), Rachel Ostroff, PhD, and colleagues from SomaLogic in Boulder, Colo., created four protein models that mimic results of the major pathologic findings in liver tissue biopsy.

“Concurrent positive results from the protein models had performance characteristics of ‘rule-out’ tests for pathologists’ diagnosis of NASH. These tests may assist in new drug development and medical intervention decisions,” they wrote in a late-breaking poster presented at the virtual annual meeting of the American Association for the Study of Liver Diseases.

“There is no single noninvasive method that can accurately and simultaneously capture steatosis, inflammation, hepatocyte ballooning and fibrosis, the four major pathologic components assessed by biopsy. Each of these is relevant to the multiple mechanisms targeted in drug development for NASH,” they wrote.

To see whether large-scale protemoics could serve as an alternative to invasive liver biopsy for use in clinical trials or in longitudinal studies of NASH, they used a modified aptamer proteomics platform to scan for liver-related proteins. Aptamers are olignonucleotide or peptide molecules designed to home in on a specific target.

They scanned for approximately 5,000 proteins in 2,852 serum samples from 638 patients in a NASH CRN natural history cohort, and in patients enrolled in two NASH treatment trials: the PIVENS trial, which is evaluating pioglitazone versus vitamin E and placebo in nondiabetic patients, and the FLINT trial, which is comparing obeticholic acid with placebo. All of the patients in the natural history cohort and half of all patients in the clinical trial cohorts were included in the training sets, with the remaining half included in the validation set.

The accuracy of the models, as measured by the area under the curve (AUC) of receiver operating characteristics in the training and validation sets, respectively, were as follows:

• Fibrosis: AUC 0.92/0.85.
• Steatosis: AUC 0.95/0.79.
• Inflammation: AUC 0.83/0.72.
• Hepatocyte Ballooning: AUC 0.87/0.83.

“A concurrent positive score for steatosis, inflammation and ballooning predicted the biopsy diagnosis of NASH with an accuracy of 73%,” Ostroff and colleagues wrote.

They also found that model scores applied over time showed improvements in symptoms in the patients on active therapies in the clinical trials, compared with patients on placebo.

A specialist in liver pathology and nonalcoholic fatty liver disease who was not involved in the study said in an interview that she finds the results highly promising.
 

Impressive results

Elizabeth M. Brunt, MD, emeritus professor of pathology and immunology at Washington University in St. Louis, was a member of the NASH CRN when SomaLogic first proposed using the groups’ data for this study.

“I was impressed with them then, and I am very impressed with what they’re presenting here, and I can’t say that about all the noninvasive tests,” she said. “I think a lot of noninvasive tests are way over-simplifying what NASH is.”

She acknowledged that, although she spent much of her career performing liver biopsies, “you can’t biopsy every single patients who you suspect of having NASH, or certainly if you want to follow them over time – it’s unrealistic,” she said in an interview.

Although the protein scanning method cannot – and is not intended to – replace a well-conducted biopsy with the interpretation of a skilled pathologist, the proteins the company investigators identified can reflect the dynamic nature of liver disease and the liver’s ability to heal itself with a high degree of accuracy and hold promise for both screening patients and for monitoring responses to therapy, Dr. Brunt said.

The study was sponsored by SomaLogic. The authors are employees of the company. Dr. Brunt had no relevant disclosures.

As study after study piles up showing that those with obesity who become infected with SARS-CoV-2 are more likely to have severe disease, several experts gave advice for clinicians and patients during the virtual ObesityWeek Interactive 2020 meeting.

Pichamol Jirapinyo, MD, MPH, associate director of bariatric endoscopy at Brigham and Women’s Hospital, Boston, presented a study on those with obesity from New England hospitals which adds to the evidence that this is “a vulnerable population for COVID-19, like elderly or immunocompromised people,” Dr. Jirapinyo said in an interview.

These findings reinforce the need for clinicians to be “more aware of complications of obesity and refer earlier for treatment,” she added.

One audience member wanted to know if there are data showing whether people with a body mass index (BMI) above 35 kg/m² who successfully lose weight subsequently have lower rates of hospitalization, ICU admission, and death if they become infected with SARS-CoV-2.

Dr. Jirapinyo said she is not aware of any such studies, but anecdotally, two of her patients who had endoscopic sleeve gastroplasty last fall (whose BMI dropped from about 38 to 30) and later became infected with COVID-19 had mild symptoms.

But David A. Kass, MD, director, Institute of CardioScience at Johns Hopkins University, Baltimore, cautioned that the biology of COVID-19 is complex in patients with obesity “and immune system dysfunction is present as are physical factors that could limit breathing.”  

“Whether this gets reversed by weight loss is an attractive hypothesis, but at this point, it’s still a hypothesis,” he stressed.
 

Changes to immunity, inflammatory signaling in obesity

“There must be north of 600 or more studies by now with this message that obesity – particularly severe obesity with a BMI of 35 and higher – is a strong independent risk factor for worse COVID-19 outcome,” Dr. Kass emphasized.

“[COVID-19] revealed to the public in a somewhat dramatic fashion that being very obese does put one at higher risk of this disease being more debilitating and even fatal,” he added.

“Before this pandemic, many viewed obesity as only a problem if you have the other associated diseases – hypertension, diabetes, heart disease, atherosclerosis, obstructive sleep apnea, etc.”

“What was not as appreciated is that marked obesity changes the body in various ways all by itself – altering metabolism, inflammatory signaling, immune surveillance, and responsiveness (including a less robust response to vaccines that has been written about as well).”  

“This is a bit like having a genetic abnormality that makes you at higher risk for getting, say, cancer,” he explained.

“It is there, it is real, it has an impact – but it still does take other stresses to reveal the risk potential. COVID-19 did that with obesity,” he said.
 

Latest study on effect of obesity, diabetes on COVID-19 severity

The study presented by Dr. Jirapinyo and colleagues identified 1,680 patients with COVID-19 at six hospitals in March 2020. Patients were a mean age of 51 years, had a mean BMI of 29.4, and 39% had obesity. Patients who required hospitalization were more likely to have obesity (46% vs. 35%; P < .0001).

Obesity was a significant risk factor for hospitalization (odds ratio, 1.7), ICU admission (OR, 1.8), and intubation (OR, 1.8; all P < .001), after controlling for age, sex, cardiovascular, pulmonary, liver, and kidney disease, and cancer. 

Compared with having a normal weight, having severe obesity was also associated with roughly threefold higher risks of ICU admission and intubation – after controlling for major comorbidities.
 

Pandemic focuses minds on obesity prevention, treatment 

Naveed Sattar, MD, PhD, said in an interview that these latest findings are “highly consistent with other studies that point to excess adiposity as a potential modifiable risk factor for more severe COVID-19.”

It “also strongly suggests that if people are worried about their risk for COVID-19 and want to improve their chances of a milder outcome, then it is reasonable to encourage them to make sustainable lifestyle changes that may lessen weight and improve their fitness levels,” said Dr. Sattar, professor of metabolic medicine, University of Glasgow.

“But of course, the big worry,” he added, “is that many are putting on weight due to lockdowns, less commuting to work, anxiety, and overeating and drinking, etc., so that many are struggling, and especially those at highest risk, such as those living in more overcrowded housing, etc. By contrast, more advantaged folk may have an easier time to improve lifestyles.”

The pandemic highlights that “we need a concerted effort on obesity prevention and treatment,” according to Dr. Sattar.

“For years we have realized links between obesity and chronic cardiometabolic conditions,” he said, “but to think excess weight may also be detrimental to acute effects of a novel virus running amok in the world has focused minds on obesity in a manner not seen before.

“Whether these new painful learnings lead to a more determined effort in countries to improve the obesogenic environment or to place more resources into prevention and management of obesity remains to be seen,” he said. 
 

Increased inquiries about bariatric surgery following COVID-19

Meanwhile, Matthew M. Hutter, MD, MPH, president, American Society for Metabolic and Bariatric Surgery, said in an interview that “COVID-19 and studies like this are now making many aware that obesity is not just a lifestyle choice or a cosmetic issue, but “a disease that needs to be taken seriously” and treated.

“Metabolic and bariatric surgery is a very safe and effective treatment for persons with obesity with a BMI >40 kg/m2 or BMI >35 kg/m2 and related diseases like diabetes, hypertension, sleep apnea, reflux, back pain, and many others,” added Dr. Hutter, who is also professor of surgery, Harvard Medical School, Boston.

“Recently, some metabolic and bariatric centers have seen an increase in patients considering surgery,” he said. “Some say that COVID-19 has made them realize they need to do something to be healthier.” 

“Currently, less than 1% of those who could benefit from surgery are actually having” it each year, Dr. Hutter noted, “and I think there are many who should seriously consider surgery to be healthier, live longer, and live better.”

One in five patients at elevated stroke risk who underwent cardiac surgery with no history of atrial fibrillation preoperatively or at discharge developed postoperative AFib documented on a continuous cardiac rhythm monitoring device within the first 30 days after leaving the hospital in the randomized SEARCH-AF trial.

“Postoperative atrial fibrillation after cardiac surgery is not confined to the hospitalization period per se. We believe that these data should help inform on clinical practice guidelines on monitoring for postoperative atrial fibrillation in such patients,” said Subodh Verma, MD, PhD, reporting the results at the virtual American Heart Association scientific sessions.

“Guidelines provide little or no direction on optimal monitoring post cardiac surgery, particularly if patients are in sinus rhythm at discharge,” the surgeon noted.

SEARCH-AF was an open-label, multicenter study that included 336 patients at elevated stroke risk with an average CHA₂DS₂-VASc score of 4, no history of preoperative AFib, and none more than briefly with resolution during hospitalization. They were randomized to 30 days of postdischarge continuous cardiac rhythm monitoring with Medtronic’s SEEQ device, to Icentia’s CardioSTAT device, or to usual care, with Holter monitoring at the discretion of the treating physicians.

The primary result was a cumulative duration of AFib or atrial flutter of 6 minutes or longer during that 30-day period. This outcome occurred in 19.6% of the enhanced cardiac monitoring group and 1.7% of usual-care controls. Thus, there is an ongoing persistent occult risk of AFib that typically goes unrecognized. This 10-fold difference in the incidence of postoperative AFib translated into an absolute 17.9% between-group difference and a number-needed-to-treat of 6.

The secondary outcome of a cumulative atrial fib/flutter burden of 6 hours or more during 30 days occurred in 8.6% of the continuously monitored group and none of the controls. A cumulative AFib/flutter burden of 24 hours or greater occurred in 3.1% of the enhanced cardiac monitoring group and zero controls. These are AFib burdens that in other studies have been linked to increased risks of stroke and death, said Dr. Verma, professor of cardiovascular surgery at the University of Toronto.

“From a clinical standpoint, what this trial tells me is for my patients being discharged home tomorrow from the hospital, where they haven’t had AFib and I haven’t initiated anticoagulation, I have a low threshold to monitor these patients and to watch for periods of sustained unrecognized atrial fibrillation,” the surgeon added.
 

Experts: Results won’t change guidelines

Discussant Ben Freedman, MBBS, PhD, noted that the U.S. Preventive Services Task Force has stated that there are insufficient data available to recommend ECG screening for AFib to prevent stroke. Before the task force can be convinced to recommend it and for payers to cover it, a number of key questions need to be answered. And the SEARCH-AF trial doesn’t provide those answers, said Dr. Freedman, professor of cardiology and deputy director of the Heart Research Institute at the University of Sydney.

First off, it’ll be necessary to know if the risk posed by screen-detected AFib, including postoperative AFib, is similar to that of clinical AFib. Next, it must be shown that this screen-detected postoperative AFib is actionable; that is, that a screening strategy to detect postoperative AFib arising after discharge and then treat with oral anticoagulants will actually prevent more strokes than with usual care. There are large studies underway addressing that question, including HEARTLINE, STROKESTOP, and SAFERGUARD-AF, he observed.

In an interview, Rod S. Passman, MD, who gave a state-of-the-art talk on AFib detection at the meeting and wasn’t involved in SEARCH-AF, said he doesn’t consider the results practice-changing.

“It’s not guideline-changing because you’ve only shown that more intensive monitoring finds more AFib. Guideline-changing would be that finding that AFib and doing something about it impacts hard outcomes, and we don’t have that data yet,” said Dr. Passman, an electrophysiologist who is director of the Center for Arrhythmia Research and professor of medicine and preventive medicine at Northwestern University, Chicago.

The SEARCH-AF trial was funded by the Heart and Stroke Foundation of Canada, Bristol Myers Squibb, Pfizer, and Boehringer Ingelheim. Dr. Verma reported having received speaker’s fees and/or research support from those and other pharmaceutical companies. Dr. Freedman disclosed having no financial conflicts.

One in five patients at elevated stroke risk who underwent cardiac surgery with no history of atrial fibrillation preoperatively or at discharge developed postoperative AFib documented on a continuous cardiac rhythm monitoring device within the first 30 days after leaving the hospital in the randomized SEARCH-AF trial.

“Postoperative atrial fibrillation after cardiac surgery is not confined to the hospitalization period per se. We believe that these data should help inform on clinical practice guidelines on monitoring for postoperative atrial fibrillation in such patients,” said Subodh Verma, MD, PhD, reporting the results at the virtual American Heart Association scientific sessions.

“Guidelines provide little or no direction on optimal monitoring post cardiac surgery, particularly if patients are in sinus rhythm at discharge,” the surgeon noted.

SEARCH-AF was an open-label, multicenter study that included 336 patients at elevated stroke risk with an average CHA₂DS₂-VASc score of 4, no history of preoperative AFib, and none more than briefly with resolution during hospitalization. They were randomized to 30 days of postdischarge continuous cardiac rhythm monitoring with Medtronic’s SEEQ device, to Icentia’s CardioSTAT device, or to usual care, with Holter monitoring at the discretion of the treating physicians.

The primary result was a cumulative duration of AFib or atrial flutter of 6 minutes or longer during that 30-day period. This outcome occurred in 19.6% of the enhanced cardiac monitoring group and 1.7% of usual-care controls. Thus, there is an ongoing persistent occult risk of AFib that typically goes unrecognized. This 10-fold difference in the incidence of postoperative AFib translated into an absolute 17.9% between-group difference and a number-needed-to-treat of 6.

The secondary outcome of a cumulative atrial fib/flutter burden of 6 hours or more during 30 days occurred in 8.6% of the continuously monitored group and none of the controls. A cumulative AFib/flutter burden of 24 hours or greater occurred in 3.1% of the enhanced cardiac monitoring group and zero controls. These are AFib burdens that in other studies have been linked to increased risks of stroke and death, said Dr. Verma, professor of cardiovascular surgery at the University of Toronto.

“From a clinical standpoint, what this trial tells me is for my patients being discharged home tomorrow from the hospital, where they haven’t had AFib and I haven’t initiated anticoagulation, I have a low threshold to monitor these patients and to watch for periods of sustained unrecognized atrial fibrillation,” the surgeon added.
 

Experts: Results won’t change guidelines

Discussant Ben Freedman, MBBS, PhD, noted that the U.S. Preventive Services Task Force has stated that there are insufficient data available to recommend ECG screening for AFib to prevent stroke. Before the task force can be convinced to recommend it and for payers to cover it, a number of key questions need to be answered. And the SEARCH-AF trial doesn’t provide those answers, said Dr. Freedman, professor of cardiology and deputy director of the Heart Research Institute at the University of Sydney.

First off, it’ll be necessary to know if the risk posed by screen-detected AFib, including postoperative AFib, is similar to that of clinical AFib. Next, it must be shown that this screen-detected postoperative AFib is actionable; that is, that a screening strategy to detect postoperative AFib arising after discharge and then treat with oral anticoagulants will actually prevent more strokes than with usual care. There are large studies underway addressing that question, including HEARTLINE, STROKESTOP, and SAFERGUARD-AF, he observed.

Cancer patients who receive an immune checkpoint inhibitor have more than a doubled rate of venous thromboembolism during the subsequent 2 years, compared with their rate during the 2 years before treatment, according to a retrospective analysis of more than 2,800 patients treated at a single U.S. center.

The study focused on cancer patients treated with an immune checkpoint inhibitor (ICI) at Massachusetts General Hospital in Boston. It showed that during the 2 years prior to treatment with any type of ICI, the incidence of venous thromboembolic events (VTE) was 4.85/100 patient-years that then jumped to 11.75/100 patient-years during the 2 years following treatment. This translated into an incidence rate ratio of 2.43 during posttreatment follow-up, compared with pretreatment, Jingyi Gong, MD, said at the virtual American Heart Association scientific sessions.

The increased VTE rate resulted from rises in both the rate of deep vein thrombosis, which had an IRR of 3.23 during the posttreatment period, and for pulmonary embolism, which showed an IRR of 2.24, said Dr. Gong, a physician at Brigham and Women’s Hospital in Boston. She hypothesized that this effect may result from a procoagulant effect of the immune activation and inflammation triggered by ICIs.


Hypothesis-generating results

Cardiologists cautioned that these findings should only be considered hypothesis generating, but raise an important alert for clinicians to have heightened awareness of the potential for VTE following ICI treatment.

“A clear message is to be aware that there is this signal, and be vigilant for patients who might present with VTE following ICI treatment,” commented Richard J. Kovacs, MD, a cardiologist and professor at Indiana University, Indianapolis. The data that Dr. Gong reported are “moderately convincing,” he added in an interview.

“Awareness that patients who receive ICI may be at increased VTE risk is very important,” agreed Umberto Campia, MD, a cardiologist, vascular specialist, and member of the cardio-oncology group at Brigham and Women’s Hospital, who was not involved in the new study.

The potential impact of ICI treatment on VTE risk is slowly emerging, added Dr. Campia. Until recently, the literature primarily was case reports, but recently another retrospective, single-center study came out that reported a 13% incidence of VTE in cancer patients following ICI treatment. On the other hand, a recently published meta-analysis of more than 20,000 patients from 68 ICI studies failed to find a suggestion of increased VTE incidence following ICI interventions.

Attempting to assess the impact of treatment on VTE risk in cancer patients is challenging because cancer itself boosts the risk. Recommendations on the use of VTE prophylaxis in cancer patients most recently came out in 2014 from the American Society of Clinical Oncology, which said that VTE prophylaxis for ambulatory cancer patients “may be considered for highly select high-risk patients.” The impact of cancer therapy on VTE risk and the need for prophylaxis is usually assessed by applying the Khorana score, Dr. Campia said in an interview.
 

VTE spikes acutely after ICI treatment

Dr. Gong analyzed VTE incidence rates by time during the total 4-year period studied, and found that the rate gradually and steadily rose with time throughout the 2 years preceding treatment, spiked immediately following ICI treatment, and then gradually and steadily fell back to roughly the rate seen just before treatment, reaching that level about a year after treatment. She ran a sensitivity analysis that excluded patients who died during the first year following their ICI treatment, and in this calculation an acute spike in VTE following ICI treatment still occurred but with reduced magnitude.

She also reported the results of several subgroup analyses. The IRRs remained consistent among women and men, among patients who were aged over or under 65 years, and regardless of cancer type or treatment with corticosteroids. But the subgroup analyses identified two parameters that seemed to clearly split VTE rates.

Among patients on treatment with an anticoagulant agent at the time of their ICI treatment, roughly 10% of the patients, the IRR was 0.56, compared with a ratio of 3.86 among the other patients, suggesting possible protection. A second factor that seemed linked with VTE incidence was the number of ICI treatment cycles a patient received. Those who received more than five cycles had a risk ratio of 3.95, while those who received five or fewer cycles had a RR of 1.66.

Her analysis included 2,842 cancer patients who received treatment with an ICI at Massachusetts General Hospital. Patients averaged 64 years of age, slightly more than half were men, and 13% had a prior history of VTE. Patients received an average of 5 ICI treatment cycles, but a quarter of the patients received more than 10 cycles.

During the 2-year follow-up, 244 patients (9%) developed VTE. The patients who developed VTE were significantly younger than those who did not, with an average age of 63 years, compared with 65. And the patients who eventually developed VTE had a significantly higher prevalence of prior VTE at 18%, compared with 12% among the patients who stayed VTE free.

The cancer types patients had were non–small cell lung, 29%; melanoma, 28%; head and neck, 12%; renal genitourinary, 6%; and other, 25%. ICIs have been available for routine U.S. practice since 2011. The class includes agents such as pembrolizumab (Keytruda) and durvalumab (Imfinzi).

Researchers would need to perform a prospective, randomized study to determine whether anticoagulant prophylaxis is clearly beneficial for patients receiving ICI treatment, Dr. Gong said. But both Dr. Kovacs and Dr. Campia said that more data on this topic are first needed.

“We need to confirm that treatment with ICI is associated with VTEs. Retrospective data are not definitive,” said Dr. Campia. “We would need to prospectively assess the impact of ICI,” which will not be easy, as it’s quickly become a cornerstone for treating many cancers. “We need to become more familiar with the adverse effects of these drugs. We are still learning about their toxicities.”

The study had no commercial funding. Dr. Gong, Dr. Kovacs, and Dr. Campia had no disclosures.

Traditional delivery of palliative care to outpatients with cancer is associated with many challenges.

Telehealth can eliminate some of these challenges but comes with issues of its own, according to results of the REACH PC trial.

Jennifer S. Temel, MD, of Massachusetts General Hospital in Boston, discussed the use of telemedicine in palliative care, including results from REACH PC, during an educational session at the ASCO Virtual Quality Care Symposium 2020.

Dr. Temel noted that, for cancer patients, an in-person visit with a palliative care specialist can cost time, induce fatigue, and increase financial burden from transportation and parking expenses.

For caregivers and family, an in-person visit may necessitate absence from family and/or work, require complex scheduling to coordinate with other office visits, and result in additional transportation and/or parking expenses.

For health care systems, to have a dedicated palliative care clinic requires precious space and financial expenditures for office personnel and other resources.

These issues make it attractive to consider whether telehealth could be used for palliative care services.
 

Scarcity of palliative care specialists

In the United States, there is roughly 1 palliative care physician for every 20,000 older adults with a life-limiting illness, according to research published in Annual Review of Public Health in 2014.

In its 2019 state-by-state report card, the Center to Advance Palliative Care noted that only 72% of U.S. hospitals with 50 or more beds have a palliative care team.

For patients with serious illnesses and those who are socioeconomically or geographically disadvantaged, palliative care is often inaccessible.

Inefficiencies in the current system are an additional impediment. Palliative care specialists frequently see patients during a portion of the patient’s routine visit to subspecialty or primary care clinics. This limits the palliative care specialist’s ability to perform comprehensive assessments and provide patient-centered care efficiently.
 

Special considerations regarding telehealth for palliative care

As a specialty, palliative care involves interactions that could make the use of telehealth problematic. For example, conveyance of interest, warmth, and touch are challenging or impossible in a video format.

Palliative care specialists engage with patients regarding relatively serious topics such as prognosis and end-of-life preferences. There is uncertainty about how those discussions would be received by patients and their caregivers via video.

Furthermore, there are logistical impediments such as prescribing opioids with video or across state lines.

Despite these concerns, the ENABLE study showed that supplementing usual oncology care with weekly (transitioning to monthly) telephone-based educational palliative care produced higher quality of life and mood than did usual oncology care alone. These results were published in JAMA in 2009.
 

REACH PC study demonstrates feasibility of telehealth model

Dr. Temel described the ongoing REACH PC trial in which palliative care is delivered via video visits and compared with in-person palliative care for patients with advanced non–small cell lung cancer.

The primary aim of REACH PC is to determine whether telehealth palliative care is equivalent to traditional palliative care in improving quality of life as a supplement to routine oncology care.

Currently, REACH PC has enrolled 581 patients at its 20 sites, spanning a geographically diverse area. Just over half of patients approached about REACH PC agreed to enroll in it. Ultimately, 1,250 enrollees are sought.

Among patients who declined to participate, 7.6% indicated “discomfort with technology” as the reason. Most refusals were due to lack of interest in research (35.1%) and/or palliative care (22.9%).

Older adults were prominent among enrollees. More than 60% were older than 60 years of age, and more than one-third were older than 70 years.

Among patients who began the trial, there were slightly more withdrawals in the telehealth participants, in comparison with in-person participants (13.6% versus 9.1%).

When palliative care clinicians were queried about video visits, 64.3% said there were no challenges. This is comparable to the 65.5% of clinicians who had no challenges with in-person visits.

When problems occurred with video visits, they were most frequently technical (19.1%). Only 1.4% of clinicians reported difficulty addressing topics that felt uncomfortable over video, and 1.5% reported difficulty establishing rapport.

The success rates of video and in-person visits were similar. About 80% of visits accomplished planned goals.
 

‘Webside’ manner

Strategies such as reflective listening and summarizing what patients say (to verify an accurate understanding of the patient’s perspective) are key to successful palliative care visits, regardless of the setting.

For telehealth visits, Dr. Temel described techniques she defined as “webside manner,” to compensate for the inability of the clinician to touch a patient. These techniques include leaning in toward the camera, nodding, and pausing to be certain the patient has finished speaking before the clinician speaks again.
 

Is telehealth the future of palliative care?

I include myself among those oncologists who have voiced concern about moving from face-to-face to remote visits for complicated consultations such as those required for palliative care. Nonetheless, from the preliminary results of the REACH PC trial, it appears that telehealth could be a valuable tool.

To minimize differences between in-person and remote delivery of palliative care, practical strategies for ensuring rapport and facilitating a trusting relationship should be defined further and disseminated.

In addition, we need to be vigilant for widening inequities of care from rapid movement to the use of technology (i.e., an equity gap). In their telehealth experience during the COVID-19 pandemic, investigators at Houston Methodist Cancer Center found that patients declining virtual visits tended to be older, lower-income, and less likely to have commercial insurance. These results were recently published in JCO Oncology Practice.

For the foregoing reasons, hybrid systems for palliative care services will probably always be needed.

Going forward, we should heed the advice of Alvin Toffler in his book Future Shock. Mr. Toffler said, “The illiterate of the 21st century will not be those who cannot read and write, but those who cannot learn, unlearn, and relearn.”

The traditional model for delivering palliative care will almost certainly need to be reimagined and relearned.

Dr. Temel disclosed institutional research funding from Pfizer.


Dr. Lyss was a community-based medical oncologist and clinical researcher for more than 35 years before his recent retirement. His clinical and research interests were focused on breast and lung cancers, as well as expanding clinical trial access to medically underserved populations. He is based in St. Louis. He has no conflicts of interest.

Traditional delivery of palliative care to outpatients with cancer is associated with many challenges.

Telehealth can eliminate some of these challenges but comes with issues of its own, according to results of the REACH PC trial.

For caregivers and family, an in-person visit may necessitate absence from family and/or work, require complex scheduling to coordinate with other office visits, and result in additional transportation and/or parking expenses.

For health care systems, to have a dedicated palliative care clinic requires precious space and financial expenditures for office personnel and other resources.

These issues make it attractive to consider whether telehealth could be used for palliative care services.
 

Scarcity of palliative care specialists

In the United States, there is roughly 1 palliative care physician for every 20,000 older adults with a life-limiting illness, according to research published in Annual Review of Public Health in 2014.

In its 2019 state-by-state report card, the Center to Advance Palliative Care noted that only 72% of U.S. hospitals with 50 or more beds have a palliative care team.

For patients with serious illnesses and those who are socioeconomically or geographically disadvantaged, palliative care is often inaccessible.

Inefficiencies in the current system are an additional impediment. Palliative care specialists frequently see patients during a portion of the patient’s routine visit to subspecialty or primary care clinics. This limits the palliative care specialist’s ability to perform comprehensive assessments and provide patient-centered care efficiently.
 

Special considerations regarding telehealth for palliative care

As a specialty, palliative care involves interactions that could make the use of telehealth problematic. For example, conveyance of interest, warmth, and touch are challenging or impossible in a video format.

Palliative care specialists engage with patients regarding relatively serious topics such as prognosis and end-of-life preferences. There is uncertainty about how those discussions would be received by patients and their caregivers via video.

Furthermore, there are logistical impediments such as prescribing opioids with video or across state lines.

Despite these concerns, the ENABLE study showed that supplementing usual oncology care with weekly (transitioning to monthly) telephone-based educational palliative care produced higher quality of life and mood than did usual oncology care alone. These results were published in JAMA in 2009.
 

REACH PC study demonstrates feasibility of telehealth model

Dr. Temel described the ongoing REACH PC trial in which palliative care is delivered via video visits and compared with in-person palliative care for patients with advanced non–small cell lung cancer.

The primary aim of REACH PC is to determine whether telehealth palliative care is equivalent to traditional palliative care in improving quality of life as a supplement to routine oncology care.

Currently, REACH PC has enrolled 581 patients at its 20 sites, spanning a geographically diverse area. Just over half of patients approached about REACH PC agreed to enroll in it. Ultimately, 1,250 enrollees are sought.

Among patients who declined to participate, 7.6% indicated “discomfort with technology” as the reason. Most refusals were due to lack of interest in research (35.1%) and/or palliative care (22.9%).

Older adults were prominent among enrollees. More than 60% were older than 60 years of age, and more than one-third were older than 70 years.

Among patients who began the trial, there were slightly more withdrawals in the telehealth participants, in comparison with in-person participants (13.6% versus 9.1%).

When palliative care clinicians were queried about video visits, 64.3% said there were no challenges. This is comparable to the 65.5% of clinicians who had no challenges with in-person visits.

When problems occurred with video visits, they were most frequently technical (19.1%). Only 1.4% of clinicians reported difficulty addressing topics that felt uncomfortable over video, and 1.5% reported difficulty establishing rapport.

The success rates of video and in-person visits were similar. About 80% of visits accomplished planned goals.
 

‘Webside’ manner

Strategies such as reflective listening and summarizing what patients say (to verify an accurate understanding of the patient’s perspective) are key to successful palliative care visits, regardless of the setting.

For telehealth visits, Dr. Temel described techniques she defined as “webside manner,” to compensate for the inability of the clinician to touch a patient. These techniques include leaning in toward the camera, nodding, and pausing to be certain the patient has finished speaking before the clinician speaks again.
 

Is telehealth the future of palliative care?

I include myself among those oncologists who have voiced concern about moving from face-to-face to remote visits for complicated consultations such as those required for palliative care. Nonetheless, from the preliminary results of the REACH PC trial, it appears that telehealth could be a valuable tool.

To minimize differences between in-person and remote delivery of palliative care, practical strategies for ensuring rapport and facilitating a trusting relationship should be defined further and disseminated.

In addition, we need to be vigilant for widening inequities of care from rapid movement to the use of technology (i.e., an equity gap). In their telehealth experience during the COVID-19 pandemic, investigators at Houston Methodist Cancer Center found that patients declining virtual visits tended to be older, lower-income, and less likely to have commercial insurance. These results were recently published in JCO Oncology Practice.

For the foregoing reasons, hybrid systems for palliative care services will probably always be needed.

Going forward, we should heed the advice of Alvin Toffler in his book Future Shock. Mr. Toffler said, “The illiterate of the 21st century will not be those who cannot read and write, but those who cannot learn, unlearn, and relearn.”

The traditional model for delivering palliative care will almost certainly need to be reimagined and relearned.

Traditional delivery of palliative care to outpatients with cancer is associated with many challenges.

Telehealth can eliminate some of these challenges but comes with issues of its own, according to results of the REACH PC trial.

The siblings of patients with bipolar disorder not only face a significantly increased lifetime risk of that affective disorder, but a whole panoply of other psychiatric disorders, according to a new Danish longitudinal national registry study.

“Our data show the healthy siblings of patients with bipolar disorder are themselves at increased risk of developing any kind of psychiatric disorder. Mainly bipolar disorder, but all other kinds as well,” Lars Vedel Kessing, MD, DMSc, said in presenting the results of the soon-to-be-published Danish study at the virtual congress of the European College of Neuropsychopharmacology.

Moreover, the long-term Danish study also demonstrated that several major psychiatric disorders follow a previously unappreciated bimodal distribution of age of onset in the siblings of patients with bipolar disorder. For example, the incidence of new-onset bipolar disorder and unipolar depression in the siblings was markedly increased during youth and early adulthood, compared with controls drawn from the general Danish population. Then, incidence rates dropped off and plateaued at a lower level in midlife before surging after age 60 years. The same was true for somatoform disorders as well as alcohol and substance use disorders.

“Strategies to prevent onset of psychiatric illness in individuals with a first-generation family history of bipolar disorder should not be limited to adolescence and early adulthood but should be lifelong, likely with differentiated age-specific approaches. And this is not now the case.

“Generally, most researchers and clinicians are focusing more on the early part of life and not the later part of life from age 60 and up, even though this is indeed also a risk period for any kind of psychiatric illness as well as bipolar disorder,” according to Dr. Kessing, professor of psychiatry at the University of Copenhagen.

Dr. Kessing, a past recipient of the Brain and Behavior Research Foundation’s Outstanding Achievement in Mood Disorders Research Award, also described his research group’s successful innovative efforts to prevent first recurrences after a single manic episode or bipolar disorder.
 

Danish national sibling study

The longitudinal registry study included all 19,995 Danish patients with a primary diagnosis of bipolar disorder during 1995-2017, along with 13,923 of their siblings and 278,460 age- and gender-matched controls drawn from the general population.

The cumulative incidence of any psychiatric disorder was 66% greater in siblings than controls. Leading the way was a 374% increased risk of bipolar disorder.
 

Strategies to prevent a first relapse of bipolar disorder

Dr. Kessing and coinvestigators demonstrated in a meta-analysis that, with current standard therapies, the risk of recurrence among patients after a single manic or mixed episode is high in both adult and pediatric patients. In three studies of adults, the risk of recurrence was 35% during the first year after recovery from the index episode and 59% at 2 years. In three studies of children and adolescents, the risk of recurrence within 1 year after recovery was 40% in children and 52% in adolescents. This makes a compelling case for starting maintenance therapy following onset of a single manic or mixed episode, according to the investigators.

More than half a decade ago, Dr. Kessing and colleagues demonstrated in a study of 4,714 Danish patients with bipolar disorder who were prescribed lithium while in a psychiatric hospital that those who started the drug for prophylaxis early – that is, following their first psychiatric contact – had a significantly higher response to lithium monotherapy than those who started it only after repeated contacts. Indeed, their risk of nonresponse to lithium prophylaxis as evidenced by repeat hospital admission after a 6-month lithium stabilization period was 13% lower than in those starting the drug later.

Early intervention aiming to stop clinical progression of bipolar disorder intuitively seems appealing, so Dr. Kessing and colleagues created a specialized outpatient mood disorders clinic combining optimized pharmacotherapy and evidence-based group psychoeducation. They then put it to the test in a clinical trial in which 158 patients discharged from an initial psychiatric hospital admission for bipolar disorder were randomized to the specialized outpatient mood disorders clinic or standard care.

The rate of psychiatric hospital readmission within the next 6 years was 40% lower in the group assigned to the specialized early intervention clinic. Their rate of adherence to medication – mostly lithium and antipsychotics – was significantly higher. So were their treatment satisfaction scores. And the clincher: The total net direct cost of treatment in the specialized mood disorders clinic averaged 3,194 euro less per patient, an 11% reduction relative to the cost of standard care, a striking economic benefit achieved mainly through avoided hospitalizations.

In a subsequent subgroup analysis of the randomized trial data, Dr. Kessing and coinvestigators demonstrated that young adults with bipolar disorder not only benefited from participation in the specialized outpatient clinic, but they appeared to have derived greater benefit than the older patients. The rehospitalization rate was 67% lower in 18- to 25-year-old patients randomized to the specialized outpatient mood disorder clinic than in standard-care controls, compared with a 32% relative risk reduction in outpatient clinic patients aged 26 years or older).

“There are now several centers around the world which also use this model involving early intervention,” Dr. Kessing said. “It is so important that, when the diagnosis is made for the first time, the patient gets sufficient evidence-based treatment comprised of mood maintenance medication as well as group-based psychoeducation, which is the psychotherapeutic intervention for which there is the strongest evidence of an effect.”

The sibling study was funded free of commercial support. Dr. Kessing reported serving as a consultant to Lundbeck.

Peanut allergy immunotherapy now comes with approval from the US Food and Drug Administration (FDA), but it also comes with protocols, standards, and paperwork. Whether it will be widely adopted has yet to be determined.

A few dozen allergists around the world have been offering food allergy immunotherapy for many years, having developed their own measuring techniques using store-bought food.

But the vast majority of allergists are not interested in developing home-grown treatments, not only because it involves research and development, but also because it comes with legal risks.

“Finally we have another treatment option,” said Edwin Kim, MD, from the UNC Allergy and Immunology Clinic in Chapel Hill, N.C. “This is what we were waiting for. It’s not cowboy stuff; this works.”

In January, the FDA approved peanut allergen powder (Palforzia) for patients 4-17 years of age, as reported by Medscape Medical News.

The pill contains measured doses of peanut flour and comes with a protocol that will allow allergists to bring patients to a peanut tolerance of 300 mg (about one peanut) and a black-box warning about anaphylaxis risk.

And before allergists can prescribe it, they must take a Risk Evaluation and Mitigation Strategy course to learn about dosing and the allergic reaction protocol.

“That may scare some away,” said Dr. Kim, who discussed the FDA-approved option during his presentation at the American College of Allergy, Asthma & Immunology 2020 Annual Scientific Meeting.

Allergic reaction, including the potential for anaphylaxis, has always been an issue with immunotherapy.

“People make the argument that there is a difference” between an expected allergic reaction – such as one that occurs after the administration of immunotherapy – and an unexpected reaction, he said. Because an expected reaction can be treated quickly, “some feel these expected reactions don’t matter so much.”

“Others say a reaction is a reaction” and argue that if, a treatment causes reaction, then it doesn’t make sense, he explained.

It comes down to patients – they must be willing to take a risk to develop tolerance and improve their quality of life – and the allergists willing to treat them.

The peanut powder involves paperwork, preauthorization forms, denials of care, a higher price tag, regimented procedures, and a prerequisite number of visits with patients. “Not everyone will want to do this,” said Dr. Kim.

The regimen involves three phases. During initial dose escalation, five doses are administered in the office on day 1. Then, over the next 6 months, updoses are administered during 11 in-office sessions and a 300-mg tolerance is achieved. Finally, to maintain tolerance to one peanut, daily doses are administered at home.

The drug cost alone is about $4,200 a year, according to Institute for Clinical and Economic Review. Peanut flour from the grocery store is cheaper, but comes with the risk of bacteria or other contamination.

“This product offers some reassurance, and that matters,” Dr. Kim said.

It’s good to have more options for food allergy treatment. “We need a more proactive way to treat food allergy; avoidance is not good enough,” he explained. “And presumably, at some point, the patient will be able to eat a grocery-store peanut instead of buying the pills.”
 

The art of medicine

But not all allergists will be able to make the protocol work. And it’s not clear whether there is room to alter treatment and offer patients with a higher tolerance a higher starting dose. What we do know, though, is that “the product leaves little room for ‘the art of medicine,’ ” Kim said.

That art is practiced by Arnon Elizur, MD, from the Shamir Medical Center in Tzrifin, Israel, but it’s backed by a rigid home-grown protocol.

Since 2010, he has treated 1,800 patients for peanut allergy, updosing slowly to a tolerance of 3,000 mg of peanut, the equivalent of 10 peanuts. He keeps the maintenance dose at four peanuts (1,200 mg). His center takes a personalized approach, starting patients on the highest dose they can tolerate and working up, with daily patient check-ins from home and a staff available around the clock to answer questions and deal with reactions.

“We aim for full sensitization,” Dr. Elizur said in an interview.

The peanut pill is “a big step forward” for immunotherapy, he said. It is “a standardized product, checked for bacteria and allergen content, which is available to a wide community of physicians.”

But, he pointed out, “it’s expensive.” And it’s only for peanut. “There are millions of food-allergic patients around the world dying from adverse reactions to many different kinds of food. We don’t want to wait for years for a product for all of them. We can use the actual food.”

He questions the lifelong maintenance protocol with a daily 300-mg pill. “If you can’t eat a peanut, why would you buy a drug that’s a peanut?” he asked.

He also said he’s disappointed that the product is not indicated for adults.

At the Shamir clinic, reactions are closely monitored. “Some are mild, others we treat with autoinjectors, epinephrine,” he reported. “Those are the most undesirable.”

Data from his center show that reactions occur in about 15% of patients. But his treatment success rates are good. In an average of 8 months, he is able to get 80% of his adult patients to full sensitization.

But it’s not for all patients or for all clinics, he acknowledged. “We continue to look at this balance in quality of life throughout the process. Our goal is to improve the quality of life threshold.”

Treatment that involves “native food” is “a lot of work” and requires “a lot of investment,” Dr. Elizur said. His center uses a web reporting system to maintain a 24/7 dialogue with patients, “and we look at the reports every day.” They also have a physician on call at all times. “Not everyone can commit to providing care throughout the day and night.”

His center charges the equivalent of $US3,000 per food allergy treated. “That’s whether it takes 6 months or 2 years,” he said.

There are more than 1,000 people on his 3-year waiting list.

“This is the first year that the American College of Allergy, Asthma, and Immunology is not hosting a pro–con debate on oral immunotherapy,” Dr. Kim pointed out. “We have a therapy now.”

However, the pandemic has slowed treatment uptake. “Immunotherapy is not easy to do, whether it’s FDA approved or not,” he explained. With at least 11 doctor visits in the first 6 months – each visit is between 30 minutes and 2-3 hours long – it hasn’t been possible to set up this year. “It’s not ideal.”

It will be interesting to see “how this will roll out and how it will be adopted,” Dr. Kim said. “From a food allergy point of view, the next 12 months are going to be very interesting.”

Dr. Kim reports receiving consulting honorarium from Aimmune, the maker of Palforzia; being on the clinical medical advisory board for DBV Technologies; and consulting for Aimmune, Allakos, Allergenis, DBV, Duke Clinical Research Institute, Ukko Incorporated, Vibrant America, and Kenota Health.

Peanut allergy immunotherapy now comes with approval from the US Food and Drug Administration (FDA), but it also comes with protocols, standards, and paperwork. Whether it will be widely adopted has yet to be determined.

A few dozen allergists around the world have been offering food allergy immunotherapy for many years, having developed their own measuring techniques using store-bought food.

But the vast majority of allergists are not interested in developing home-grown treatments, not only because it involves research and development, but also because it comes with legal risks.

“Finally we have another treatment option,” said Edwin Kim, MD, from the UNC Allergy and Immunology Clinic in Chapel Hill, N.C. “This is what we were waiting for. It’s not cowboy stuff; this works.”

In January, the FDA approved peanut allergen powder (Palforzia) for patients 4-17 years of age, as reported by Medscape Medical News.

The pill contains measured doses of peanut flour and comes with a protocol that will allow allergists to bring patients to a peanut tolerance of 300 mg (about one peanut) and a black-box warning about anaphylaxis risk.

And before allergists can prescribe it, they must take a Risk Evaluation and Mitigation Strategy course to learn about dosing and the allergic reaction protocol.

“That may scare some away,” said Dr. Kim, who discussed the FDA-approved option during his presentation at the American College of Allergy, Asthma & Immunology 2020 Annual Scientific Meeting.

Allergic reaction, including the potential for anaphylaxis, has always been an issue with immunotherapy.

“People make the argument that there is a difference” between an expected allergic reaction – such as one that occurs after the administration of immunotherapy – and an unexpected reaction, he said. Because an expected reaction can be treated quickly, “some feel these expected reactions don’t matter so much.”

“Others say a reaction is a reaction” and argue that if, a treatment causes reaction, then it doesn’t make sense, he explained.

It comes down to patients – they must be willing to take a risk to develop tolerance and improve their quality of life – and the allergists willing to treat them.

The peanut powder involves paperwork, preauthorization forms, denials of care, a higher price tag, regimented procedures, and a prerequisite number of visits with patients. “Not everyone will want to do this,” said Dr. Kim.

The regimen involves three phases. During initial dose escalation, five doses are administered in the office on day 1. Then, over the next 6 months, updoses are administered during 11 in-office sessions and a 300-mg tolerance is achieved. Finally, to maintain tolerance to one peanut, daily doses are administered at home.

The drug cost alone is about $4,200 a year, according to Institute for Clinical and Economic Review. Peanut flour from the grocery store is cheaper, but comes with the risk of bacteria or other contamination.

“This product offers some reassurance, and that matters,” Dr. Kim said.

It’s good to have more options for food allergy treatment. “We need a more proactive way to treat food allergy; avoidance is not good enough,” he explained. “And presumably, at some point, the patient will be able to eat a grocery-store peanut instead of buying the pills.”
 

The art of medicine

But not all allergists will be able to make the protocol work. And it’s not clear whether there is room to alter treatment and offer patients with a higher tolerance a higher starting dose. What we do know, though, is that “the product leaves little room for ‘the art of medicine,’ ” Kim said.

That art is practiced by Arnon Elizur, MD, from the Shamir Medical Center in Tzrifin, Israel, but it’s backed by a rigid home-grown protocol.

Since 2010, he has treated 1,800 patients for peanut allergy, updosing slowly to a tolerance of 3,000 mg of peanut, the equivalent of 10 peanuts. He keeps the maintenance dose at four peanuts (1,200 mg). His center takes a personalized approach, starting patients on the highest dose they can tolerate and working up, with daily patient check-ins from home and a staff available around the clock to answer questions and deal with reactions.

“We aim for full sensitization,” Dr. Elizur said in an interview.

The peanut pill is “a big step forward” for immunotherapy, he said. It is “a standardized product, checked for bacteria and allergen content, which is available to a wide community of physicians.”

But, he pointed out, “it’s expensive.” And it’s only for peanut. “There are millions of food-allergic patients around the world dying from adverse reactions to many different kinds of food. We don’t want to wait for years for a product for all of them. We can use the actual food.”

He questions the lifelong maintenance protocol with a daily 300-mg pill. “If you can’t eat a peanut, why would you buy a drug that’s a peanut?” he asked.

He also said he’s disappointed that the product is not indicated for adults.

At the Shamir clinic, reactions are closely monitored. “Some are mild, others we treat with autoinjectors, epinephrine,” he reported. “Those are the most undesirable.”

Data from his center show that reactions occur in about 15% of patients. But his treatment success rates are good. In an average of 8 months, he is able to get 80% of his adult patients to full sensitization.

But it’s not for all patients or for all clinics, he acknowledged. “We continue to look at this balance in quality of life throughout the process. Our goal is to improve the quality of life threshold.”

Treatment that involves “native food” is “a lot of work” and requires “a lot of investment,” Dr. Elizur said. His center uses a web reporting system to maintain a 24/7 dialogue with patients, “and we look at the reports every day.” They also have a physician on call at all times. “Not everyone can commit to providing care throughout the day and night.”

His center charges the equivalent of $US3,000 per food allergy treated. “That’s whether it takes 6 months or 2 years,” he said.

There are more than 1,000 people on his 3-year waiting list.

Routinely collected clinical data help identify men with high-risk prostate cancer most likely to benefit from a gallium-68 prostate-specific membrane antigen (PSMA) PET/CT scan, according to a study reported at the American Society for Radiation Oncology Annual Meeting 2020.

“PSMA PET/CT is a novel molecular and functional imaging modality specific for prostate cancer cells that has good sensitivity and outstanding specificity in detecting metastasis,” noted study investigator T. Martin Ma, MD, PhD, of the University of California, Los Angeles.

The proPSMA trial, published in The Lancet earlier this year, found PSMA PET/CT to be superior to conventional imaging for primary staging of high-risk prostate cancer.

“These findings carry significant clinical implications and can affect treatment decision-making,” Dr. Ma noted.

With the current study, Dr. Ma and colleagues set out to assess the impact of PSMA PET/CT in nodal and metastatic upstaging in patients with high-risk prostate cancer and explore predictors of upstaging.

The researchers conducted a post hoc analysis of a single-center, prospective study of 262 patients with high-risk prostate cancer (cN1 or cN0 on conventional imaging) undergoing primary staging. Patients who had received 3 or more months of androgen deprivation therapy before their scan were excluded.
 

Study results

PSMA PET/CT led to nodal upstaging – from N0 to N1 – in 19.7% of patients and metastasis upstaging – from M0 to M1a, b, or c – in 9.4%.

“It is worth pointing out that the percentage of upstaging at the PSMA scan in our study is very similar to that in the proPSMA study,” Dr. Ma noted, with that trial finding nodal upstaging in 18% of patients and metastasis upstaging in 8%.

In multivariate analysis, independent predictors of nodal upstaging with PSMA PET/CT were higher percentage of positive cores at biopsy (odds ratio per decile, 1.21; P = .001) and higher Gleason grade (OR, 1.61; P = .025).

Similarly, independent predictors of metastasis upstaging were higher percentage of positive cores at biopsy (OR per decile, 1.19; P = .013) and higher Gleason grade (OR, 2.13; P = .024).

Other factors – clinical T stage and N stage, initial prostate-specific antigen level, and presence of two or more high-risk features – did not independently predict these outcomes.

When various combinations were assessed, the incidence of nodal upstaging was highest for patients who had a Gleason grade of 4 or 5 plus at least 50% positive cores (27.5% vs. 13.1% among all others). Similarly, incidence of metastasis upstaging was highest for those who had a Gleason grade of 5 plus at least 50% positive cores (20.6% vs. 5.9% among all others).

“Patients with percent-positive cores of 50% or more and Gleason grade group 4 or 5 will benefit the most from a PSMA PET/CT scan,” Dr. Ma concluded. “Future studies should validate the importance of these factors and identify whether changing treatment leads to improved outcomes.”

“The beauty of percent-positive cores is that it is an objective and routinely available piece of clinical information from systematic biopsy,” he added. “It may aid in the selection of patients in resource-limited settings and consideration of treatment intensification. We may also consider incorporation of percent positive cores into clinical risk stratification schemes for clinical use.”
 

A game changer

“PSMA PET has been a real game changer in high-risk prostate cancer and has implications in the various stages of prostate cancer management from diagnosis and staging to theranostics,” said Renu Eapen, MBBS, of Peter MacCallum Cancer Centre in Melbourne, who was not involved in this study.

“PSMA PET/CT has challenged conventional imaging in staging before curative intent surgery or radiotherapy,” Dr. Eapen added.

Accuracy of PSMA PET/CT was 27% higher than that of conventional imaging in the proPSMA trial, she noted in an interview. This superior accuracy can ultimately have management impact, while the imaging has additional benefits of lower radiation dose and reproducibility with high reporter agreement, potentially making it a “one-stop-shop” scan.

“This prospective study by Ma et al. is a great adjunct to the proPSMA results, with the aims of further stratifying patients who are likely to be upstaged on PSMA PET/CT,” Dr. Eapen said. “As the availability of PSMA PET/CT increases and more centers adopt this technology, we need studies like these to risk-stratify patients and select those who would benefit.”

The study did not receive any specific funding. Dr. Ma and Dr. Eapen disclosed no conflicts of interest.

A novel randomized trial taking on a vexing issue around one of the world’s most commonly prescribed medications has concluded that frequently intolerable statin side effects, such as muscle weakness or pain, are almost entirely a nocebo effect, the placebo effect’s darker cousin.

The many patients who report such symptoms while taking statins are indeed probably feeling them, but they are a result of taking the pills rather than any pharmacologic effects, concluded researchers based on their 60-patient study, Self-Assessment Method for Statin Side-effects or Nocebo (SAMSON).

“SAMSON leaves no doubt that patients really do get side effects from statin tablets, but what it shows us is that 90% of this symptomatic burden is elicited by placebo tablets too,” said James P. Howard, MB, PhD, Imperial College London, when presenting the results Nov. 15 at the American Heart Association scientific sessions. They were published simultaneously in the New England Journal of Medicine.

Studies have shown that in practice “more than half of patients abandon statins completely within 2 years. And yet, in placebo-controlled trials, no more people stop statins than placebo,” Dr. Howard said.

“The most important message from SAMSON is that side effects from statin tablets are very real, but they are mainly caused by the act of taking the tablets, not by the statin that is contained within them.”
Patients in the trial, all of whom had a history of dropping statins because of side effects, each took atorvastatin 20 mg/day, a placebo, or neither pill for 1 month, alternating the regimens in randomized order over 1 year so that each was followed a total of 4 months. They used a smartphone app to record the severity of any side effects, not necessarily just pain, on a scale of 0-100.

Symptom intensity scores averaged 16.3 for atorvastatin and 15.4 for placebo, for a nonsignificant difference, but only 8.0 for no-pill months (P < .001 compared with the statin or placebo).
Because such symptoms seem to be based on patient expectations from statin therapy, positive communication about what the drugs can achieve and how the next treatment steps are described can play a big role in their continued use.

For example, “changing them to another statin is a very reasonable thing to do, but as soon as you start trying people on lower doses and working up, you’re sort of telling them that you’re expecting at some dose that they are going to get side effects,” cautioned Dr. Howard at a media briefing on SAMSON.

“The most important thing is to explain the evidence, and what our expectations are, maybe be a bit more optimistic about statins, and tell them they’re very unlikely to suffer from side effects,” he explained, “because the nocebo effect can only really rear its head if the patients are expecting to feel worse – just like the placebo effect will only work if people are expecting to feel better.”
Amit Khera, MD, who moderated the media briefing, said he always tells such patients: “Yes, 1 in 10 patients report having muscle ache. But first and foremost, 9 in 10 don’t. The vast majority of patients don’t get muscle aches. I think that’s really an important part of the communication.”

Now, after SAMSON, “I have an additional point that I’m going to tell them: out of the patients that get muscle aches, probably 90% of that is the anticipation of getting the statin, the nocebo effect,” said Dr. Khera, who directs the preventive cardiology program at the University of Texas Southwestern Medical Center, Dallas.

In practice, however, many patients who report adverse statin effects do so later than 2 weeks after starting therapy, “so these findings cannot be generalized to them,” proposed Francine K. Welty, MD, PhD, Beth Israel Deaconess Medical Center, Boston, as the invited discussant after Dr. Howard’s presentation.

All 60 patients recruited for SAMSON had previously stopped taking a statin because of side effects that arose within 2 weeks of their first dose. That requirement was intended to boost chances that any further symptoms during the trial would arise within a month of starting each new round of pills, Dr. Howard said.

So the trial’s results, Dr. Welty said, “are limited to those subjects who develop symptoms within 2 weeks of starting a statin.”

Including only such patients may have created bias toward a nocebo effect, she said, because “non–drug-related side effects of medications are often greatest during the initial weeks of treatment and tend to abate over time.” For example, “metformin causes diarrhea and beta-blockers cause fatigue, but subjects do adapt and generally tolerate them very well.”

The patients, 25 women and 35 men, 90% of whom were white, received four pill bottles, each with a month’s supply of atorvastatin, four bottles each with 1 month of placebo, and four empty bottles each, to be used double blind for a month in randomized order.

Patients used the smartphone app to document their symptom scores, which ranged from 0 for no symptoms to 100 for symptoms that were the “worst imaginable,” the published report noted. Patients who experienced symptoms so severe as to be intolerable could stop the 1-month regimen they were then following, with instructions to resume the regimens in order starting the next month.

Eleven patients were unable to complete all 12 1-month segments of the trial.

The study’s overall “nocebo ratio” of 0.90 was calculated as the difference between symptom intensity scores on placebo and on no treatment divided by the difference between symptom intensity on the statin and on no treatment. The interpretation: 90% of the symptom burden felt by patients receiving atorvastatin was also felt during placebo use.

A total of 30 patients, contacted 6 months after the trial concluded, had resumed taking a statin, while “4 planned to do so and one could not be contacted,” the report noted. The 25 other patients weren’t receiving a statin and had no plans to take one.

In an important part of the trial, Dr. Howard said, at its conclusion the patients were shown their pattern of symptoms in relation to whether they were taking the statin, placebo, or neither. “Participants could see as clearly as we could the surprisingly powerful magnitude of the nocebo effect. And this led to half of our patients happily restarting statins.”

The implications of SAMSON, Dr. Welty said, “are very important, in that those developing symptoms within 2 weeks of starting a statin should be reassured that approximately half will be able to successful restart the statin.”

SAMSON was funded by the British Heart Foundation. Howard had no disclosures. Dr. Welty disclosed chairing the data safety monitoring committee for Empagliflozin International Clinical Trials, supported by Boehringer Ingelheim.

A novel randomized trial taking on a vexing issue around one of the world’s most commonly prescribed medications has concluded that frequently intolerable statin side effects, such as muscle weakness or pain, are almost entirely a nocebo effect, the placebo effect’s darker cousin.

The many patients who report such symptoms while taking statins are indeed probably feeling them, but they are a result of taking the pills rather than any pharmacologic effects, concluded researchers based on their 60-patient study, Self-Assessment Method for Statin Side-effects or Nocebo (SAMSON).

“SAMSON leaves no doubt that patients really do get side effects from statin tablets, but what it shows us is that 90% of this symptomatic burden is elicited by placebo tablets too,” said James P. Howard, MB, PhD, Imperial College London, when presenting the results Nov. 15 at the American Heart Association scientific sessions. They were published simultaneously in the New England Journal of Medicine.

Studies have shown that in practice “more than half of patients abandon statins completely within 2 years. And yet, in placebo-controlled trials, no more people stop statins than placebo,” Dr. Howard said.

“The most important message from SAMSON is that side effects from statin tablets are very real, but they are mainly caused by the act of taking the tablets, not by the statin that is contained within them.”
Patients in the trial, all of whom had a history of dropping statins because of side effects, each took atorvastatin 20 mg/day, a placebo, or neither pill for 1 month, alternating the regimens in randomized order over 1 year so that each was followed a total of 4 months. They used a smartphone app to record the severity of any side effects, not necessarily just pain, on a scale of 0-100.

Symptom intensity scores averaged 16.3 for atorvastatin and 15.4 for placebo, for a nonsignificant difference, but only 8.0 for no-pill months (P < .001 compared with the statin or placebo).
Because such symptoms seem to be based on patient expectations from statin therapy, positive communication about what the drugs can achieve and how the next treatment steps are described can play a big role in their continued use.

For example, “changing them to another statin is a very reasonable thing to do, but as soon as you start trying people on lower doses and working up, you’re sort of telling them that you’re expecting at some dose that they are going to get side effects,” cautioned Dr. Howard at a media briefing on SAMSON.

“The most important thing is to explain the evidence, and what our expectations are, maybe be a bit more optimistic about statins, and tell them they’re very unlikely to suffer from side effects,” he explained, “because the nocebo effect can only really rear its head if the patients are expecting to feel worse – just like the placebo effect will only work if people are expecting to feel better.”
Amit Khera, MD, who moderated the media briefing, said he always tells such patients: “Yes, 1 in 10 patients report having muscle ache. But first and foremost, 9 in 10 don’t. The vast majority of patients don’t get muscle aches. I think that’s really an important part of the communication.”

Now, after SAMSON, “I have an additional point that I’m going to tell them: out of the patients that get muscle aches, probably 90% of that is the anticipation of getting the statin, the nocebo effect,” said Dr. Khera, who directs the preventive cardiology program at the University of Texas Southwestern Medical Center, Dallas.

In practice, however, many patients who report adverse statin effects do so later than 2 weeks after starting therapy, “so these findings cannot be generalized to them,” proposed Francine K. Welty, MD, PhD, Beth Israel Deaconess Medical Center, Boston, as the invited discussant after Dr. Howard’s presentation.

All 60 patients recruited for SAMSON had previously stopped taking a statin because of side effects that arose within 2 weeks of their first dose. That requirement was intended to boost chances that any further symptoms during the trial would arise within a month of starting each new round of pills, Dr. Howard said.

So the trial’s results, Dr. Welty said, “are limited to those subjects who develop symptoms within 2 weeks of starting a statin.”

Including only such patients may have created bias toward a nocebo effect, she said, because “non–drug-related side effects of medications are often greatest during the initial weeks of treatment and tend to abate over time.” For example, “metformin causes diarrhea and beta-blockers cause fatigue, but subjects do adapt and generally tolerate them very well.”

Having a low threshold to biopsy atypical pigmented lesions on the vulva may identify melanoma early, according to a lecture at virtual conference on diseases of the vulva and vagina, hosted by the International Society for the Study of Vulvovaginal Disease.

Pigmented brown or black vulvar lesions occur in approximately 10% of women, and they may be normal and benign.

“Often we will see a pigmented lesion on the vulva and think that there is nothing to worry about,” said Melissa Mauskar, MD.

Lesions could be angiokeratomas, petechiae, purpura, melanosis, and nevi, for example. Seborrheic keratoses can mimic melanoma. “If it looks odd, don’t be afraid to biopsy it,” said Dr. Mauskar, assistant professor of dermatology and obstetrics and gynecology at the University of Texas Southwestern Medical Center in Dallas.

Characteristics of melanoma, covered by the mnemonic ABCDE, include asymmetry, borders that are irregular, coloring that is uneven, diameter greater than 7 mm, and evolution over time.

When biopsying a lesion because of concerns about melanoma, the goal is to remove the whole lesion at once, Dr. Mauskar said.

In a recent U.S. population-based study of more than 1,800 patients with malignant melanoma of the vulva or vagina (including 1,400 patients with vulvar melanoma and 463 patients with vaginal melanoma), median disease-specific survival was 99 months for vulvar melanoma and 19 months for vaginal melanoma.

Patients with vaginal melanoma were more likely than patients with vulvar melanoma to have nodular lesions. The American Joint Committee on Cancer staging system predicts vulvar melanoma outcomes, the researchers found. In addition, lymph node status and mitotic rate were important predictors of survival.

A wide local excision is the mainstay of therapy for melanoma. Other therapeutic advances are “changing the survival curves for these patients, especially when we can find things early,” Dr. Mauskar said.

Photographing lesions can help doctors monitor them over time, she added.

It is important for dermatologists to include the vulva in skin exams and for gynecologists to have a low threshold to biopsy atypical pigmented lesions, Dr. Mauskar said. “Having a very low threshold for biopsy ... will increase our chances of finding these lesions when they are more at the superficial spreading phase as opposed to the nodular phase,” she said.

Capturing the depth of a tumor within the confines of a biopsy may help accurately stage malignant melanoma, Jason Reutter, MD, a pathologist in Hickory, N.C., said in a separate presentation. He suggested trying to get around the lesion with a punch biopsy if possible. A shave biopsy may be advantageous for larger macular lesions. To diagnose one melanoma, doctors may have to biopsy many lesions, Dr. Reutter noted.

At one institution, the number of skin biopsies needed to diagnose skin cancer ranged from 2.82 to 6.55, depending on the type of clinician, according to a recent study. The number of biopsies needed to detect one melanoma was greater – between 14 and 54 – depending on type of clinician.

For larger lesions, scouting biopsies of different areas may be the best approach, Dr. Reutter said.

Dr. Mauskar and Dr. Reutter had no relevant financial conflicts of interest.
