Conference Coverage

BOSTON – In patients with primary progressive multiple sclerosis (PPMS), machine learning can predict progression with reasonable accuracy on the basis of the blood transcriptome, according to a proof-of-concept study presented at the 2023 annual meeting of the American Academy of Neurology.

The accuracy was sufficient for the lead author of the study, Michael Gurevich, PhD, head of the Neuroimmunological Laboratory in the Multiple Sclerosis Center of Sheba Medical Center in Ramat Gan, Israel, to say that it is already clinically viable even as the tool is still evolving.

“We are looking at larger sample sizes to improve the accuracy and generalizability of our model, but we can use it now to inform treatment decisions,” Dr. Gurevich said.

In patients with PPMS who have a highly variable course, the model predicts disability progression with an accuracy of approximately 70%, according to the data he presented. He said he believes this is already at a level that it is meaningful for a risk-to-benefit calculation when considering treatment.
 

Machine learning analyzes blood samples

The study pursues the concept that the genetic information governing highly complex pathophysiological processes is contained in RNA sequencing. While multimodal omics generate data that are too complex for human pattern recognition, there is a growing body of evidence, including that provided by this study, to suggest that machine learning can employ these same RNA profiles and predict disease activity.

In this study, blood samples were collected from patients who participated in the phase 3 clinical ORATORIO trial that led to approval of ocrelizumab for PPMS. Analyses were conducted only on blood samples from those randomized to placebo, who, like those in the active treatment arm, were evaluated at baseline and at 12-week intervals for more than 2 years.

After development of a prediction model and creation of a training dataset, machine learning was applied to the deep sequencing of the blood transcriptome data for predicting two endpoints. One was disease progression at 120 weeks defined as a 1 point or more increase in the Expanded Disability Status Scale (EDSS) among patients with confirmed disability progression for at least 12 weeks (12W-CDP).

The other was change at 120 weeks in brain morphology defined as a 1% or more reduction in brain volume (120W PBVC).

The peripheral blood samples were subjected to RNA sequencing analysis (RNA-Seq) using commercially available analysis techniques. The prediction model for the disability endpoint was based on data generated from the blood transcriptome of 135 patients of which 53 (39%) met the endpoint at 120 weeks. The prediction model for the change in brain morphology was based on the blood transcriptome from 94 patients of which 63 (67%) met the endpoint.

On the basis of 10 genes that most significantly differentiated those who met the disability endpoint from those who did not, machine recognition of patterns after training was able to predict correctly the outcome in 70.9%. The sensitivity was 55.6%, and the specificity was 79.0%. The positive and negative predictive values were 59.0% and 76.8%, respectively.

On the basis of the 12 genes the most significantly differentiated those that reached the 120W PBVC endpoint from those who did not, machine learning resulted in a correct prediction of outcomes in 75.1%. The sensitivity was 78.1%, and the specificity was 66.7%. The positive and negative predictive values were 83.3% and 58.8%, respectively

Typical of a PPMS trial population, the mean age of the patients was about 44 years. The mean disease duration was about 6 years. The majority of patients had an EDSS score below 5.5 at baseline. The baseline T2 lesion number was approximately 50.

If further validated by others and in larger studies, this type of information could play a valuable role in PPMS management, according to Dr. Gurevich. Now that there is an approved therapy for PPMS, it can help clinicians and patients determine whether to initiate treatment early to address the high risk of progression or delay treatment that might not be needed.
 

A useful tool

In the field of MS, most of the studies performed with machine learning have focused on the analysis of radiological images. However, others are now looking at the blood transcriptome as a potential path to better classifying a highly complex disease with substantial heterogeneity in presentation, progression, and outcome.

For example, machine learning of the blood transcriptome has also shown high accuracy in the diagnosis and classification of MS in patients with clinically isolated syndrome (CIS). One study, published in Cell Reports Medicine, was led by Cinthia Farina, PhD, Institute of Experimental Neurology, IRCCS San Raffaele Scientific Institute, Milan.

Although she did not hear the presentation by Dr. Gurevich, Dr. Farina is enthusiastic about the potential for machine learning to help manage MS through the analysis of the blood transcriptome. “I do believe that transcriptomics in peripheral immune cells may become a useful tool for MS diagnosis and prognosis,” she said.

In her own study, in which machine learning algorithms were developed and trained on the basis of peripheral blood from patients with CIS, the tool proved accurate with a strong potential for being incorporated into routine clinical management.

“Machine learning applied to the blood transcriptomes was extremely efficient with a 95.6% accuracy in discriminating PPMS from RRMS [relapsing-remitting] MS,” she reported.

Dr. Gurevich has no potential financial conflicts of interest to report. He reported funding for the study was provided by Roche. Dr. Farina reports financial relationships with Merck-Serono, Novartis, and Teva.

MONTPELLIER, FRANCE – The first expert consensus on smoking and diabetes, coauthored by the Francophone Diabetes Society (SFD) and the French Society for the Study of Nicotine Addiction (SFT), was presented at the SFD’s annual conference.

Alexia Rouland, MD, an endocrinologist at Dijon Bourgogne University Hospital, Dijon, France, took the conference as an opportunity to list the many benefits of smoking cessation for patients with diabetes, despite the “slight and temporary” risk for blood sugar imbalance.
 

Societies target smoking

Diabetes societies around Europe have set their sights on the topic of smoking. Indeed, the guidelines published in 2019 by the European Association for the Study of Diabetes and the European Society of Cardiology state that “smoking cessation is obligatory for all prediabetic and diabetic patients” (class I, level A).

This year, the France-based SFD and SFT dedicated an expert consensus to the major problem of smoking in patients with diabetes. The aim was to provide health care professionals with convincing, well-supported arguments in favor of smoking cessation in their patients with type 1 and type 2 diabetes.

“Before anything else, diabetic patients need to be made aware of the risks of smoking,” said Dr. Rouland. “It’s not just about the fear factor, though. It’s also about providing a positive incentive – they need to be told about the ways they’ll benefit from quitting smoking. For example, you have all-cause mortality, macro- and microangiopathic complications, and so on.”
 

Duration of abstinence

“Diabetic patients who have stopped smoking have a relative risk for all-cause mortality of 1.28 (1.09-1.51), which is less than what you see in active smokers (relative risk = 1.58; 1.42-1.77), but still above that of nonsmokers,” said Dr. Rouland.

A previous study revealed that although the risk does indeed go down after stopping smoking, it is linked to how long ago the person stopped. Patients who stopped smoking less than 10 years ago still had a slightly raised all-cause mortality risk, and this was even higher if they had smoked for 20 years or more.

After 10 years of not smoking, however, the greater all-cause mortality risk was no longer significant in any of the groups monitored (smoking duration, number of cigarettes/day). Concrete evidence of the link between all-cause mortality and the length of time since a person stopped smoking also emerged from the large cohort in the American Nurses’ Health Study.

The relative risk for all-cause mortality in women who stopped smoking less than 5 years ago remained high (RR = 1.96, 1.47-2.67), then decreased over time. After 10 years, it was no longer significant (RR = 1.11, 0.92-1.35).
 

Macro- and microangiopathic risks

Smoking cessation also has a real benefit in terms of the increased macro- and microangiopathic risks. In type 2 diabetes, a study found an increased relative risk for macro- and microalbuminuria of 1.86 (95% confidence interval, 1.37-2.52) in former smokers, compared with an increased relative risk of 2.61 (95% CI, 1.86-2.64) in current smokers.

In type 1 diabetes, the cumulative risk for microalbuminuria in former smokers was 15.1% vs. 18.9% in smokers and 10% in nonsmokers.

A 2019 meta-analysis of prospective cohort studies determined that smoking is an independent risk factor for diabetic nephropathy, especially in patients with type 1 diabetes.

Yet, most of the data for this condition come from subjects with type 2 diabetes. One publication estimated its prevalence after a 1-year follow-up of the smoking cessation program as 10.9% in former smokers and 15% in those who continued smoking.

In regard to macroangiopathy in the context of type 2 diabetes, the aforementioned 2019 meta-analysis focused on coronary artery disease, cerebrovascular accident (CVA), cardiovascular mortality, and myocardial infarction (MI). It found that smokers face an increased risk for all these outcomes.

The relative risks wavered between 1.53 and 1.66 and decreased after smoking cessation. For coronary artery disease and MI, they became insignificant. There was still a risk for CVA (RR = 1.34; 1.07-1.67) and fatal cardiovascular events (RR = 1.19; 0.02-1.39).

The data are slightly more heterogeneous for type 1 diabetes, where, despite smoking cessation, the increased risk for heart failure and CVA persists in men, yet the same risk for coronary heart disease and CVA drops in women.
 

Risk for weight gain

Dr. Rouland tried to reassure patients about the risk for gaining weight. “Weight gain is not inevitable. There is a risk for this, but it’s temporary. And, even with some weight gain, the cardiovascular benefits are still indisputable.”

A study carried out in 2013 focused specifically on this point, with an average post-cessation weight gain of 3.8 kg (8.4 lb) seen in diabetic individuals in the first 4 years after stopping smoking and of 0.1 kg (0.2 lb) thereafter. A time-based effect was observed with regulation of excess weight post-cessation over time, as seen in the general population (3 kg [6.6 lb] on average in nondiabetic individuals).

Weight gain tends to occur mainly in the immediate post-cessation period, essentially in the first 3 months, and there is a large variation in weight change. Some people gain a lot (from 5 to 10 kg [11 to 22 lb], or even more than 10 kg); others lose weight (20% of diabetic former smokers in the first month, 7% after 12 months), and 25% gain less than 5 kg (11 lb).
 

Blood glucose imbalance

“A risk for blood glucose imbalance has been reported after smoking cessation, although this is very slight and only temporary,” said Dr. Rouland.

A British retrospective study examined this question, focusing on glycated hemoglobin in patients with type 2 diabetes. Hemoglobin A1c increased by 0.21% (95% CI, 0.17-0.25; P < .001) within the first year after quitting. A1c decreased as abstinence continued and became comparable to that of continual smokers after 3 years. This increase in A1c was not mediated by weight change.

Another study published in 2018 on the topic of type 2 diabetes also reported on the risk for poor glycemic control (defined as A1c > 7%) persisting for 10 years after smoking cessation (odds ratio, 1.23; 95% CI, 1.06-1.42). Thereafter, between 10 and 19 years post-cessation, the OR decreased to 0.97 (95% CI, 0.80-1.19, NS). Beyond 20 years post-cessation, the OR was 1.14 (95% CI, 0.89-1.44, NS) and was therefore no longer significant.

Regardless, “the risk for poor glycemic control is lower in quitters than in active smokers,” said Dr. Rouland.
 

Quitting and diabetes risk

Will a smoker’s increased risk for diabetes drop when he or she stops smoking? “This is essentially what happens,” Dr. Rouland confirmed, “and his or her increased risk for metabolic syndrome also drops. One meta-analysis revealed a time-based effect.

“Patients who had stopped smoking less than 5 years previously had an increased relative risk for type 2 diabetes, and this risk dropped to 1.11 after more than 10 years of not smoking. Moreover, this relative risk for type 2 diabetes remained lower than that of active smokers, at between 1.19 and 1.60, depending on tobacco use.”

In regard to the risk for metabolic syndrome, those who quit smoking seem to have an increased risk of 10%, compared with nonsmokers (RR = 1.10, 1.08-1.11; P < .001). “But yet again, this increased risk is much lower than that of active smokers, whose risk is between 37% (less than 20 cigarettes/day) and 71% (more than 20 cigarettes/day).”
 

Women with diabetes

“The benefits of quitting appear identical, regardless of the sex of the diabetic person,” said Dr. Rouland. “As in the general population, weight gain after smoking cessation is greater in women. Furthermore, while smoking increases the risk for gestational diabetes (RR, 1.4-1.9) and for the use of insulin in this context, stopping smoking reduces these risks.

“Moreover, smoking during pregnancy not only increases the risk for pregnancy-related complications (early miscarriage, ectopic pregnancy, birth defects, placental abruption, premature birth, intrauterine fetal demise, cesarean birth, low birth weight), but it also increases the risk of type 2 diabetes in the newborn. The risk to the newborn is said to be around 34% in cases in which the mother smokes during pregnancy and 22% in cases in which the mother is a passive smoker, thereby justifying the use of measures to help the mother’s family members to stop smoking.”

Dr. Rouland reports no relevant financial relationships.

The risk to the newborn is said to be around 34% in cases in which the mother smokes during pregnancy and 22% in cases in which the mother is a passive smoker, thereby justifying the use of measures to help the mother’s family members to stop smoking.”

MONTPELLIER, FRANCE – The first expert consensus on smoking and diabetes, coauthored by the Francophone Diabetes Society (SFD) and the French Society for the Study of Nicotine Addiction (SFT), was presented at the SFD’s annual conference.

Alexia Rouland, MD, an endocrinologist at Dijon Bourgogne University Hospital, Dijon, France, took the conference as an opportunity to list the many benefits of smoking cessation for patients with diabetes, despite the “slight and temporary” risk for blood sugar imbalance.
 

Societies target smoking

Diabetes societies around Europe have set their sights on the topic of smoking. Indeed, the guidelines published in 2019 by the European Association for the Study of Diabetes and the European Society of Cardiology state that “smoking cessation is obligatory for all prediabetic and diabetic patients” (class I, level A).

This year, the France-based SFD and SFT dedicated an expert consensus to the major problem of smoking in patients with diabetes. The aim was to provide health care professionals with convincing, well-supported arguments in favor of smoking cessation in their patients with type 1 and type 2 diabetes.

“Before anything else, diabetic patients need to be made aware of the risks of smoking,” said Dr. Rouland. “It’s not just about the fear factor, though. It’s also about providing a positive incentive – they need to be told about the ways they’ll benefit from quitting smoking. For example, you have all-cause mortality, macro- and microangiopathic complications, and so on.”
 

Duration of abstinence

“Diabetic patients who have stopped smoking have a relative risk for all-cause mortality of 1.28 (1.09-1.51), which is less than what you see in active smokers (relative risk = 1.58; 1.42-1.77), but still above that of nonsmokers,” said Dr. Rouland.

A previous study revealed that although the risk does indeed go down after stopping smoking, it is linked to how long ago the person stopped. Patients who stopped smoking less than 10 years ago still had a slightly raised all-cause mortality risk, and this was even higher if they had smoked for 20 years or more.

After 10 years of not smoking, however, the greater all-cause mortality risk was no longer significant in any of the groups monitored (smoking duration, number of cigarettes/day). Concrete evidence of the link between all-cause mortality and the length of time since a person stopped smoking also emerged from the large cohort in the American Nurses’ Health Study.

The relative risk for all-cause mortality in women who stopped smoking less than 5 years ago remained high (RR = 1.96, 1.47-2.67), then decreased over time. After 10 years, it was no longer significant (RR = 1.11, 0.92-1.35).
 

Macro- and microangiopathic risks

Smoking cessation also has a real benefit in terms of the increased macro- and microangiopathic risks. In type 2 diabetes, a study found an increased relative risk for macro- and microalbuminuria of 1.86 (95% confidence interval, 1.37-2.52) in former smokers, compared with an increased relative risk of 2.61 (95% CI, 1.86-2.64) in current smokers.

In type 1 diabetes, the cumulative risk for microalbuminuria in former smokers was 15.1% vs. 18.9% in smokers and 10% in nonsmokers.

A 2019 meta-analysis of prospective cohort studies determined that smoking is an independent risk factor for diabetic nephropathy, especially in patients with type 1 diabetes.

Yet, most of the data for this condition come from subjects with type 2 diabetes. One publication estimated its prevalence after a 1-year follow-up of the smoking cessation program as 10.9% in former smokers and 15% in those who continued smoking.

In regard to macroangiopathy in the context of type 2 diabetes, the aforementioned 2019 meta-analysis focused on coronary artery disease, cerebrovascular accident (CVA), cardiovascular mortality, and myocardial infarction (MI). It found that smokers face an increased risk for all these outcomes.

The relative risks wavered between 1.53 and 1.66 and decreased after smoking cessation. For coronary artery disease and MI, they became insignificant. There was still a risk for CVA (RR = 1.34; 1.07-1.67) and fatal cardiovascular events (RR = 1.19; 0.02-1.39).

The data are slightly more heterogeneous for type 1 diabetes, where, despite smoking cessation, the increased risk for heart failure and CVA persists in men, yet the same risk for coronary heart disease and CVA drops in women.
 

Risk for weight gain

Dr. Rouland tried to reassure patients about the risk for gaining weight. “Weight gain is not inevitable. There is a risk for this, but it’s temporary. And, even with some weight gain, the cardiovascular benefits are still indisputable.”

A study carried out in 2013 focused specifically on this point, with an average post-cessation weight gain of 3.8 kg (8.4 lb) seen in diabetic individuals in the first 4 years after stopping smoking and of 0.1 kg (0.2 lb) thereafter. A time-based effect was observed with regulation of excess weight post-cessation over time, as seen in the general population (3 kg [6.6 lb] on average in nondiabetic individuals).

Weight gain tends to occur mainly in the immediate post-cessation period, essentially in the first 3 months, and there is a large variation in weight change. Some people gain a lot (from 5 to 10 kg [11 to 22 lb], or even more than 10 kg); others lose weight (20% of diabetic former smokers in the first month, 7% after 12 months), and 25% gain less than 5 kg (11 lb).
 

Blood glucose imbalance

“A risk for blood glucose imbalance has been reported after smoking cessation, although this is very slight and only temporary,” said Dr. Rouland.

A British retrospective study examined this question, focusing on glycated hemoglobin in patients with type 2 diabetes. Hemoglobin A1c increased by 0.21% (95% CI, 0.17-0.25; P < .001) within the first year after quitting. A1c decreased as abstinence continued and became comparable to that of continual smokers after 3 years. This increase in A1c was not mediated by weight change.

Another study published in 2018 on the topic of type 2 diabetes also reported on the risk for poor glycemic control (defined as A1c > 7%) persisting for 10 years after smoking cessation (odds ratio, 1.23; 95% CI, 1.06-1.42). Thereafter, between 10 and 19 years post-cessation, the OR decreased to 0.97 (95% CI, 0.80-1.19, NS). Beyond 20 years post-cessation, the OR was 1.14 (95% CI, 0.89-1.44, NS) and was therefore no longer significant.

Regardless, “the risk for poor glycemic control is lower in quitters than in active smokers,” said Dr. Rouland.
 

Quitting and diabetes risk

Will a smoker’s increased risk for diabetes drop when he or she stops smoking? “This is essentially what happens,” Dr. Rouland confirmed, “and his or her increased risk for metabolic syndrome also drops. One meta-analysis revealed a time-based effect.

“Patients who had stopped smoking less than 5 years previously had an increased relative risk for type 2 diabetes, and this risk dropped to 1.11 after more than 10 years of not smoking. Moreover, this relative risk for type 2 diabetes remained lower than that of active smokers, at between 1.19 and 1.60, depending on tobacco use.”

In regard to the risk for metabolic syndrome, those who quit smoking seem to have an increased risk of 10%, compared with nonsmokers (RR = 1.10, 1.08-1.11; P < .001). “But yet again, this increased risk is much lower than that of active smokers, whose risk is between 37% (less than 20 cigarettes/day) and 71% (more than 20 cigarettes/day).”
 

Women with diabetes

“The benefits of quitting appear identical, regardless of the sex of the diabetic person,” said Dr. Rouland. “As in the general population, weight gain after smoking cessation is greater in women. Furthermore, while smoking increases the risk for gestational diabetes (RR, 1.4-1.9) and for the use of insulin in this context, stopping smoking reduces these risks.

“Moreover, smoking during pregnancy not only increases the risk for pregnancy-related complications (early miscarriage, ectopic pregnancy, birth defects, placental abruption, premature birth, intrauterine fetal demise, cesarean birth, low birth weight), but it also increases the risk of type 2 diabetes in the newborn. The risk to the newborn is said to be around 34% in cases in which the mother smokes during pregnancy and 22% in cases in which the mother is a passive smoker, thereby justifying the use of measures to help the mother’s family members to stop smoking.”

PARIS – For orchestra musicians, performance is everything. So, it’s no wonder that musculoskeletal disorders – a reality for so many of these professionals – are not openly discussed. Physical pain is often pushed aside, unexpressed, until one day the suffering gets to be too much, the ability to play is impacted, and all the effort to keep things under wraps and under control culminates in burnout.

Anne Maugue was one of the speakers at the French College of General Medicine’s 16th Congress of General Medicine. Ms. Maugue is a postdoctoral researcher at Côte d’Azur University, Nice, France. She also plays flute in the Monte-Carlo Philharmonic Orchestra. Through her presentation to the physicians, she sought to raise awareness about MSDs in professional musicians, as well as the associated psychosocial risk factors. “If caught early enough, this pain can often be successfully treated.”
 

High prevalence

“You’re a violinist in a major symphony orchestra. It’s Sunday night, 8 o’clock, and you’ve just come off the stage. A few minutes ago, you felt a sharp pain in your right arm – a pain that is now, already, overwhelming. The conductor accused you of not being focused, of not concentrating. You know that you have another rehearsal in just a few hours, Monday morning. So, what do you do – other than hope that the pain goes away by then? Where can you turn to get help?”

With this opening scenario, Ms. Maugue was able to immediately orient the attendees to the realities that professional musicians face.

Pain is far from anecdotal. In professional orchestras, its prevalence over 12 months is between 41% and 93%. “An elite athlete has a full training staff they can turn to. An elite musician, on the other hand, usually only has their general practitioner – and that’s assuming the musician even reaches out to get treatment to begin with.

“The fact is that most of the time musicians only care about the pain when it becomes chronic, when it causes discomfort that affects their playing,” said Ms. Maugue.

How, then, does one evaluate this problem? In a Danish study, musicians rated the musculoskeletal problems they had experienced in the preceding 7 days. When the researchers compared those reports with findings from a clinical examination, they found that the examiners were not able to identify which musicians had reported problems. Why? Because a diagnosis does not reflect the severity or the impact, both of which are subjective.

“When faced with pain, the musician’s initial reaction is denial,” said Ms. Maugue. “The pain is often attributed to something other than the physicality of playing their instrument. They then turn to self-care, to colleagues. It’s only much later that they consult a medical professional.”

As a result, the physician is seldom aware of the musician’s psychological distress and has no sense of how long it’s been since the pain first started.
 

Work environment

Carrying around an instrument all the time and maintaining nonergonomic postures for extended periods are just two of the factors that put professional musicians at risk of physical pain. Not to be forgotten, Ms. Maugue added, are the work-related pressures. Musicians are not immune to issues with their work environment. They can feel like they aren’t getting the resources they need, proper recognition from their leaders, or support from their colleagues. In the end, such feelings can engender a sense of unfairness – and that acts as a stressor that can give rise to MSDs.

Evidence of this phenomenon can be found in the results of a study that Ms. Maugue conducted. Out of 440 French orchestra musicians (44% women), 64% said they had experienced MSD-related pain in the preceding 12 months and 61% in the preceding 7 days.

Using industrial and organizational psychology scales of measurement, Ms. Maugue was able to show, through hierarchical regression, that “emotional exhaustion and MSD-related pain occur when the environment in which people work causes them to feel a sense of unfairness.”
 

Early detection

Finally, Ms. Maugue encouraged general practitioners to ask every patient whether he or she plays a musical instrument. If the answer is yes, get an idea about any pain that he or she may have been feeling in the back, neck, and upper extremities so that prompt treatment can be given.

“There are other studies underway that are looking to better characterize instrumental activity and to enable more effective management by sports medicine departments,” said Ms. Maugue. “But back to patients with MSDs. It’s important to understand everything about their playing. Where do they practice? How often do they practice? What’s their posture like when they play? What’s the tempo of the music they’re working on? Because what we see in professional musicians is likely to be seen in amateur musicians as well – particularly in young people who study at a conservatory,” where not much is being done to prevent MSDs.

“If professional musicians are given treatment early on, half of them can be permanently cured,” she concluded. “And then, just like elite athletes, they’ll be able to get right back to playing.”

ORLANDO – Patients with hepatocellular carcinoma (HCC) who undergo surgery or thermal ablation with curative intent are at high risk for recurrence, but currently, no adjuvant therapy standard of care exists for these patients.

New findings signal a promising option for these patients. The combination of the immune checkpoint inhibitor atezolizumab (Tecentriq) and the angiogenesis inhibitor bevacizumab (Avastin) was associated with a significant improvement in recurrence-free survival, compared with active surveillance, and represents the first option to show efficacy in the adjuvant setting following surgical resection of HCCs for patients at high risk for recurrence.

The recurrence-free survival benefit corresponded to a 28% reduced risk of recurrence or death among patients who received the combination therapy in comparison with active surveillance. However, the overall survival data remain immature.

The data come from an interim analysis of the IMbrave050 trial, which was presented at the annual meeting of the American Association for Cancer Research.

“Atezolizumab plus bevacizumab may be a practice-changing adjuvant treatment options for patients with high-risk HCC,” said lead investigator Pierce Chow, MBBS, PhD, codirector of the National Cancer Centre Singapore Comprehensive Liver Cancer Clinic. He presented the results in an oral abstract session at the meeting. The combination “may also change clinical indications for surgical resection” because clinicians may be more likely to consider resection for patients at extremely high risk for recurrence if the risk of recurrence can be reduced with this combination.

In the previous IMbrave150 trial, the combination of atezolizumab and bevacizumab significantly improved outcomes for patients with high-risk and non–high-risk unresectable HCC, compared with the standard of care sorafenib (Nexavar).

In that trial, the median overall survival in the intention-to-treat population was 19.2 months for patients who received atezolizumab-bevacizumab versus 13.4 months for patients who received sorafenib (P = .0009).

The combination was also associated with improvements in progression-free survival and objective response rates, compared with sorafenib.

On the basis of these results, the IMbrave050 investigators explored whether the same benefits would occur for patients with resectable disease considered to be at high risk for recurrence owing to tumor size, vascular invasion, or poor tumor differentiation. The trial compared the combination for 334 patients with active surveillance, also for 334 patients, in the adjuvant setting.

Patients were considered good candidates for thermal ablation if they had a single tumor greater than 2 cm, but not larger than 5 cm in its longest dimension, or if they had four or fewer tumors, all of which were no larger than 5 cm. For all other patients, surgical resection was recommended.

The median age of the patients was 60. For about half of patients in each arm, the expression level of programmed death–ligand-1 (PD-L1) was 1% or higher.

After a median follow-up of 17.4 months, the 12-month recurrence-free survival rate, as assessed by independent review, was 78% for patients in the treatment arm, compared with 65% for patients who were assigned to active surveillance (hazard ratio, 0.72; P = .012). This finding was generally consistent across clinical subgroups, including groups based on age, sex, race/ethnicity, performance status, PD-L1 expression, number of high-risk features, Barcelona Clinic Liver Cancer stage, cancer etiology, procedure type, microvascular invasion, or tumor numbers and size.

Of 133 patients on active surveillance who experienced a protocol-defined recurrence event, 81 (61%) crossed over to the atezolizumab/bevacizumab arm.

The overall survival benefit of the combination therapy was less clear. Dr. Chow called the overall survival data “highly immature” at the time of data cutoff.

Overall, 47 patients died – 7 more in the combination arm (27 vs. 20). More specifically, 17 patients in the combination arm and 16 on active surveillance died from progressive disease; 6 patients in the treatment arm versus 1 on surveillance died from adverse events. The remaining deaths were attributed to other causes. Two deaths in the combination arm were considered treatment related, one from esophageal varices hemorrhage, and the other from ischemic stroke.

Dr. Chow said a number of deaths attributed to HCC recurrence was similar between the groups. There were three COVID-19–related deaths within 1 year of randomization, all in the combination arm.

As for adverse events, the safety of the combination was largely consistent with that reported in the IMbrave150 trial. Nearly all patients experienced at least one adverse event. Treatment-related grade 3 or 4 adverse events occurred in 34.9% of patients in the combination group, and serious treatment-related events occurred in 13.3%.

The most common adverse events of any grade were proteinuria, hypertension, decreased platelet count, increases in liver enzyme level, hypothyroidism, arthralgia, pruritus, rash, increase in serum bilirubin level, and fever.

Invited discussant Stephen L. Chan, MD, from the Chinese University of Hong Kong, said the study was “definitely” relevant to clinicians and addresses “a very important unmet need.”

Dr. Chan noted that he thinks this combination will “likely” be practice changing, given the improvement in recurrence-free survival, but “certainly we need more data to guide us in patient selection.”

The study was funded by F. Hoffman–La Roche. Dr. Chow has consulting for and has received honoraria and grant/research support from Roche and others. Dr. Chan has received honoraria from Roche and consulting fees and grant/research support from others.

More specifically, 17 patients in the combination arm and 16 on active surveillance died from progressive disease; 6 patients in the treatment arm versus 1 on surveillance died from adverse events. The remaining deaths were attributed to other causes. Two deaths in the combination arm were considered treatment related, one from esophageal varices hemorrhage, and the other from ischemic stroke.

Dr. Chow said a number of deaths attributed to HCC recurrence was similar between the groups. There were three COVID-19–related deaths within 1 year of randomization, all in the combination arm.

As for adverse events, the safety of the combination was largely consistent with that reported in the IMbrave150 trial. Nearly all patients experienced at least one adverse event. Treatment-related grade 3 or 4 adverse events occurred in 34.9% of patients in the combination group, and serious treatment-related events occurred in 13.3%.

The most common adverse events of any grade were proteinuria, hypertension, decreased platelet count, increases in liver enzyme level, hypothyroidism, arthralgia, pruritus, rash, increase in serum bilirubin level, and fever.

Invited discussant Stephen L. Chan, MD, from the Chinese University of Hong Kong, said the study was “definitely” relevant to clinicians and addresses “a very important unmet need.”

Dr. Chan noted that he thinks this combination will “likely” be practice changing, given the improvement in recurrence-free survival, but “certainly we need more data to guide us in patient selection.”

The study was funded by F. Hoffman–La Roche. Dr. Chow has consulting for and has received honoraria and grant/research support from Roche and others. Dr. Chan has received honoraria from Roche and consulting fees and grant/research support from others.

ORLANDO – Patients with hepatocellular carcinoma (HCC) who undergo surgery or thermal ablation with curative intent are at high risk for recurrence, but currently, no adjuvant therapy standard of care exists for these patients.

New findings signal a promising option for these patients. The combination of the immune checkpoint inhibitor atezolizumab (Tecentriq) and the angiogenesis inhibitor bevacizumab (Avastin) was associated with a significant improvement in recurrence-free survival, compared with active surveillance, and represents the first option to show efficacy in the adjuvant setting following surgical resection of HCCs for patients at high risk for recurrence.

The recurrence-free survival benefit corresponded to a 28% reduced risk of recurrence or death among patients who received the combination therapy in comparison with active surveillance. However, the overall survival data remain immature.

The data come from an interim analysis of the IMbrave050 trial, which was presented at the annual meeting of the American Association for Cancer Research.

“Atezolizumab plus bevacizumab may be a practice-changing adjuvant treatment options for patients with high-risk HCC,” said lead investigator Pierce Chow, MBBS, PhD, codirector of the National Cancer Centre Singapore Comprehensive Liver Cancer Clinic. He presented the results in an oral abstract session at the meeting. The combination “may also change clinical indications for surgical resection” because clinicians may be more likely to consider resection for patients at extremely high risk for recurrence if the risk of recurrence can be reduced with this combination.

In the previous IMbrave150 trial, the combination of atezolizumab and bevacizumab significantly improved outcomes for patients with high-risk and non–high-risk unresectable HCC, compared with the standard of care sorafenib (Nexavar).

In that trial, the median overall survival in the intention-to-treat population was 19.2 months for patients who received atezolizumab-bevacizumab versus 13.4 months for patients who received sorafenib (P = .0009).

The combination was also associated with improvements in progression-free survival and objective response rates, compared with sorafenib.

On the basis of these results, the IMbrave050 investigators explored whether the same benefits would occur for patients with resectable disease considered to be at high risk for recurrence owing to tumor size, vascular invasion, or poor tumor differentiation. The trial compared the combination for 334 patients with active surveillance, also for 334 patients, in the adjuvant setting.

Patients were considered good candidates for thermal ablation if they had a single tumor greater than 2 cm, but not larger than 5 cm in its longest dimension, or if they had four or fewer tumors, all of which were no larger than 5 cm. For all other patients, surgical resection was recommended.

The median age of the patients was 60. For about half of patients in each arm, the expression level of programmed death–ligand-1 (PD-L1) was 1% or higher.

After a median follow-up of 17.4 months, the 12-month recurrence-free survival rate, as assessed by independent review, was 78% for patients in the treatment arm, compared with 65% for patients who were assigned to active surveillance (hazard ratio, 0.72; P = .012). This finding was generally consistent across clinical subgroups, including groups based on age, sex, race/ethnicity, performance status, PD-L1 expression, number of high-risk features, Barcelona Clinic Liver Cancer stage, cancer etiology, procedure type, microvascular invasion, or tumor numbers and size.

Of 133 patients on active surveillance who experienced a protocol-defined recurrence event, 81 (61%) crossed over to the atezolizumab/bevacizumab arm.

The overall survival benefit of the combination therapy was less clear. Dr. Chow called the overall survival data “highly immature” at the time of data cutoff.

Overall, 47 patients died – 7 more in the combination arm (27 vs. 20). More specifically, 17 patients in the combination arm and 16 on active surveillance died from progressive disease; 6 patients in the treatment arm versus 1 on surveillance died from adverse events.

PHOENIX – Combining a serum containing silymarin with nonablative laser therapy could serve as a promising solution for decreasing inflammation, postinflammatory erythema (PIE), and postinflammatory hyperpigmentation (PIH) associated with acne lesions, results from a prospective, single-center study showed.

“Acne vulgaris is the most common inflammatory dermatosis worldwide, often resulting in sequelae such as scarring, PIE, and PIH,” presenting author Jamie Hu, MD, said at the annual conference of the American Society for Laser Medicine and Surgery, where the study results were presented during an abstract session. “This dyschromia can cause greater psychological distress than the original acne lesions, and disproportionately affects skin of color patients.”

Blemish-prone skin is known to have higher levels of sebum and lower levels of antioxidants, leading to lipid peroxidation and oxidative stress, resulting in proliferation of Cutibacterium acnes and an inflammatory cascade that has recently been implicated in postinflammatory dyschromia and the development of PIE and PIH, noted Dr. Hu, a dermatology resident at the University of Miami. “Therefore, the use of antioxidants presents an opportunity to disrupt blemish and dyschromia,” she said.

One such antioxidant is silymarin, which is derived from the milk thistle plant. Recent studies have demonstrated that silymarin reduces proinflammatory mediators, prevents lipid peroxidation, and presents a new way to target the treatment of both acne and postinflammatory dyschromia.

Dr. Hu’s mentor, Jill S. Waibel, MD, owner and medical director of the Miami Dermatology and Laser Institute, hypothesized that nonablative laser therapy followed by topical application of silymarin would improve acne-associated postinflammatory dyschromia. To test her hunch, she conducted a 12-week, prospective trial in which 24 patients with PIE and/or PIH were randomized to one of two treatment arms: laser treatment with topical antioxidants or laser treatment with vehicle control. Patients received three laser treatments, each 1 month apart. The topical antioxidant used was Silymarin CF, a serum that contains 0.5% silymarin, 0.5% salicylic acid, 15% L-ascorbic acid, and 0.5% ferulic acid. (The study was sponsored by SkinCeuticals, the manufacturer of the serum.)

Laser selection was made primarily on the type of dyschromia, with PIE patients receiving treatment with the pulsed dye laser and PIH patients receiving treatment with the 1,927-nm thulium laser. Patients were treated on days 0, 28, and 56 of the 12-week study, followed by immediate application of topical antioxidants or vehicle control. They were also instructed to apply the assigned topical twice daily for the duration of the study. Patients ranged in age from 21 to 61 years, and 20 had skin types III-IV.

To evaluate efficacy, the researchers conducted blinded clinical assessments with the postacne hyperpigmentation index (PAHPI) and the Global Aesthetic Improvement Scale (GAIS), instrumentation with the Mexameter, a device that captures erythema and melanin index values, and visual diagnostics with optical coherence tomography (OCT).

Dr. Hu reported that at week 12, the PAHPI in the silymarin-plus-laser treatment group fell from an average of 3.18 to 1.74 (a decrease of 1.44), which suggested an improvement trend, compared with the laser treatment–only group, whose PAHPI fell from an average of 3.25 to 1.97 (a decrease of 1.28).

As for the GAIS, a one-time score assessed at the end of the trial, the average score for all patients was 3.24, which translated to “much improved/very much improved.” Patients in the silymarin-plus-laser treatment group had higher average scores compared with patients in the laser treatment–only group (3.35 vs. 3.10, respectively), but the differences did not reach statistical significance.

According to results of the Mexameter assessment, paired t-tests showed that the levels of intralesional melanin decreased significantly for patients in the silymarin-plus-laser treatment group, compared with the laser treatment–only group (P < .05). OCT assessments demonstrated an increase in dermal brightness in both groups, corresponding to an increase in dermal collagen, as well as an increase in blood vessel density.

In an interview at the meeting, Dr. Waibel, subsection chief of dermatology at Baptist Hospital of Miami, said that future studies will focus on long-term follow-up to determine if acne scars can be prevented by combining silymarin with lasers to prevent PIH and PIE. “That would be priceless,” she said. “I believe that the PIH is what causes damage to the collagen, and that damage to the collagen is what causes the scarring. So, if we can prevent or treat PIH, we may be able to prevent scarring.”

This approach, she added, “would decrease the pharmaceutical cost because I think there are many dermatologists who are treating PEI and PIH as active acne. You really have to have a keen eye for understanding the differences and you really have to be looking, because PIE and PIH are flat, whereas active acne consists of either comedones or nodules.”

She noted that in skin of color patients, she has seen PIH persist for 9 or 10 months after treatment with isotretinoin. “It’s not the isotretinoin causing the scars, or even the acne, it’s the prolonged inflammation,” she said.

Catherine M. DiGiorgio, MD, a Boston-based laser and cosmetic dermatologist who was asked to comment on the study, said that patients and dermatologists frequently seek alternatives to hydroquinone for unwanted hyperpigmentation.

“While the study failed to show statistically significant improvement in postinflammatory erythema with concomitant laser and topical therapy versus laser alone, the promising data supporting concurrent use of topicals and fractional lasers for treatment of PIH, particularly in dark skin phototypes, is a clinically impactful contribution to our daily practice,” he said.

Dr. Waibel disclosed that she has conducted clinical trials for many device and pharmaceutical companies including SkinCeuticals. Dr. Hu, Dr. DiGiorgio, and Dr. Jalian were not involved with the study and reported having no relevant disclosures.

Liver transplant is an effective therapy for patients with primary liver cancer, and outcomes after transplantation are often superior to surgical resection. But the pool of potential patients is increasing, as transplantation is now emerging as an attractive option for select patients with nonresectable colorectal cancer (CRC) liver metastases, as well as those with intrahepatic cholangiocarcinoma (CCA).

Experts in the field highlighted some of the current challenges and opportunities in transplant oncology during a special session at the ASCO Gastrointestinal Cancers Symposium.
 

Transplant is here to stay

To date, the only curative or potentially curative therapy for patients with CRC liver metastases and intrahepatic CCA has been the combination of systemic therapies and R0 resection, said Gonzalo Sapisochin Cantis, MD, associate professor, department of surgery, University of Toronto.

The new idea is that, for patients with unresectable disease, total hepatectomy followed by a liver transplant may be a promising strategy. “This is a very hot topic in transplant oncology,” he said.

Liver transplantation is already established as the best treatment option for patients with primary hepatocellular carcinoma, which has become the main indication for liver transplantation at many centers.

For patients with CRC metastases and intrahepatic CCA, liver transplantation may help cure some patients by extending the conventional margins of surgical oncology, he suggested. “This is basically going to work in patients who have exclusive liver-restricted disease and not in those with metastatic disease. The efficacy is going to be seen by objective and sustained response to some sort of neoadjuvant therapy.”

However, Dr. Sapisochin emphasized liver transplantation is not an option for every patient. “We’re going to have to have clear inclusion and exclusion criteria that need to be defined a priori.”

Intrahepatic CCA has historically been considered a contraindication for liver transplantation. Surgical resection is the preferred first-line treatment and the only one that is potentially curative, he explained. However, most patients are not candidates for surgery, and even if they do have a resection, many of these patients will experience a recurrence, usually in the liver.

There are some studies that support transplantation in this patient population, including one by Dr. Sapisochin and colleagues. That study looked at patients who were transplanted under the assumption that they had hepatocellular carcinoma but were found to actually have intrahepatic CCA. The recurrence rate at 5 years was 18%, and 5-year survival was 65%.

“We were able to show that those patients with small tumors actually can do very well after transplant, with survivals over 70%-80%, which in this population is a very good outcome,” he said.
 

Transplant for CRC metastases

Unresectable liver metastases from colorectal cancer can also be challenging to treat, he said. Surgical resection is the only potential cure with a combination of systemic chemotherapy, but only a minority of patients are candidates for surgery.

Data supporting transplantation for CRC metastases have been emerging. One trial was conducted by researchers in Norway, who developed the Oslo score for risk stratification. “Those with risk factors had worse outcomes, and obviously, having a large tumor diameter, a high CEA (carcinoembryonic antigen), progressing on chemotherapy, or a short interval between the primary resection and the transplant were risk factors for recurrence,” Dr. Sapisochin said.

The 10-year survival among patients with a low Oslo score was 50%. “We’re talking about patients who had no resection possibility and received a transplant after systemic chemotherapy, and they had a 10-year survival of 50%,” he emphasized.

However, Dr. Sapisochin acknowledged the biggest problem transplant surgeons face is that there are not enough donor organs.

One solution is living donor liver transplantation. “Given that this is an unlimited source, you can utilize this as extended criteria and it adds another graft to the system,” he explained.

“We have a protocol for living donor liver transplantations for patients with colorectal liver metastasis,” Dr. Sapisochin said. “We’ve done seven cases so far with pretty good outcomes. One patient, unfortunately, passed away 39 months after transplant with lung metastases, but the rest are alive with no recurrence.”*
 

More available organs?

R. Mark Ghobrial, MD, PhD, director of the J.C. Walter Jr. Transplant Center at Houston Methodist Hospital, said that, 5 years ago, he was very cautious about liver transplantation for intrahepatic CCA.

He pointed out that, although transplantation for hepatocellular cancer was being done in the 1990s, the results were so poor that a moratorium was placed on the practice. “But now liver transplantation has become the definitive therapy for hepatocellular cancer, and intrahepatic cholangiocarcinoma is going the same way,” he said.

Dr. Ghobrial reiterated that one of the issues in transplantation for oncology patients is the limited supply of available organs, but he believes the landscape for liver transplantation has changed, resulting in more available organs. One factor is that hepatitis C has become curable with the advent of new therapies, and hence, the need for transplantation for patients with this disease has plummeted.

“I’ve done about maybe 800 transplants in the last 5 years. I’ve only transplanted two patients with hepatitis C,” he said. “Now we are doing more transplants for alcoholic liver disease and cancer.”

Improvements in technology are also allowing for more livers to become useable, he pointed out. One example is normothermic machine perfusion, which has entered the clinical arena in the last decade. The technique has shown promising results in improving the quality of marginal organs and increasing the pool of liver grafts.

Another factor that has increased the number of livers available for transplantation is the move to accept organs from circulatory death donors, as well as donations after brain death. “Our transplantation was about 4% of donors after cardiac death, but today this has gone up to almost 16% or 20% of the livers,” Dr. Ghobrial said. “In some centers this has gone up to about 50%.

“Liver transplantation for intrahepatic cholangiocarcinoma and colorectal cancer metastases has come of age for selected patients,” he said.

More caution needed

However, another expert urged some caution, warning that live donation carries risk. Yuman Fong, MD, a surgical oncologist with City of Hope National Medical Center, Duarte, Calif., said that around “1 in 600 live donors die from donation. That is a healthy person dying. This is not a small issue.”

He pointed out that if the criteria for transplant is greatly liberalized, the 5-year survival will not be as high as demonstrated in clinical trials.

Writing about the issue in a recent editorial, Dr. Fong pointed out that cadaveric livers for transplant remain a finite resource and that more than 1,000 patients still die every year on the waiting list for a transplant.

A more reasonable approach would be to advocate for this type of program in regions of the world where cadaveric livers are more plentiful or centers with established living donor transplant programs.

“For us to develop this resource and safeguard patients, family organ donors, and resources, we need to develop what are the best inclusion criteria,” Dr. Fong said. “We have to optimize use of all cadaveric organs and determine if we are willing to transplant borderline organs.”
 

Ethics of transplanting

Ethicist Arthur L. Caplan, PhD, the Drs. William F. and Virginia Connolly Mitty Professor of Bioethics at New York University, said this is an interesting development in the field of liver transplantation. “There have been attempts in the past, and many did not end well, such as with Steve Jobs. But transplantation is always pushing to expand eligibility, and there has also been much success with that.”

However, Dr. Caplan emphasized the new data are innovative and experimental, which may control how many centers will be able to perform liver transplants in these cancer patient populations. “It has to be data driven as we are dealing with an exceedingly scarce source,” he said. “We know that people can do well, but it adds more stress to the supply of organs, and some patients may not do as well.”

He also emphasized that live donation is not a panacea. “Liver donation from a live donor is not the same as live donation for a kidney. It is much riskier and not that common. So not quite the same.”

The bottom line is that livers for transplantation are a scarce resource and transplant may work well in some cancer patients but not others, he emphasized. “Morally, we want to save lives, but not by adding in people who may not do well. If programs try to stretch the criteria, some may try transplants with more marginal organs.”

Dr. Sapisochin has disclosed relationships with Bayer, Roche, Novartis, Integra, AstraZeneca, Chiesi, Evidera, and Stryker. Dr. Ghobrial reported no relevant financial relationships. Dr. Fong has reported being a scientific consultant for Medtronic and Johnson & Johnson and receiving royalties from Merck and Imugene. Dr. Caplan writes a regular column on ethics for Medscape.

The new idea is that, for patients with unresectable disease, total hepatectomy followed by a liver transplant may be a promising strategy. “This is a very hot topic in transplant oncology,” he said.

Liver transplantation is already established as the best treatment option for patients with primary hepatocellular carcinoma, which has become the main indication for liver transplantation at many centers.

For patients with CRC metastases and intrahepatic CCA, liver transplantation may help cure some patients by extending the conventional margins of surgical oncology, he suggested. “This is basically going to work in patients who have exclusive liver-restricted disease and not in those with metastatic disease. The efficacy is going to be seen by objective and sustained response to some sort of neoadjuvant therapy.”

However, Dr. Sapisochin emphasized liver transplantation is not an option for every patient. “We’re going to have to have clear inclusion and exclusion criteria that need to be defined a priori.”

Intrahepatic CCA has historically been considered a contraindication for liver transplantation. Surgical resection is the preferred first-line treatment and the only one that is potentially curative, he explained. However, most patients are not candidates for surgery, and even if they do have a resection, many of these patients will experience a recurrence, usually in the liver.

There are some studies that support transplantation in this patient population, including one by Dr. Sapisochin and colleagues. That study looked at patients who were transplanted under the assumption that they had hepatocellular carcinoma but were found to actually have intrahepatic CCA. The recurrence rate at 5 years was 18%, and 5-year survival was 65%.

“We were able to show that those patients with small tumors actually can do very well after transplant, with survivals over 70%-80%, which in this population is a very good outcome,” he said.
 

Transplant for CRC metastases

Unresectable liver metastases from colorectal cancer can also be challenging to treat, he said. Surgical resection is the only potential cure with a combination of systemic chemotherapy, but only a minority of patients are candidates for surgery.

Data supporting transplantation for CRC metastases have been emerging. One trial was conducted by researchers in Norway, who developed the Oslo score for risk stratification. “Those with risk factors had worse outcomes, and obviously, having a large tumor diameter, a high CEA (carcinoembryonic antigen), progressing on chemotherapy, or a short interval between the primary resection and the transplant were risk factors for recurrence,” Dr. Sapisochin said.

The 10-year survival among patients with a low Oslo score was 50%. “We’re talking about patients who had no resection possibility and received a transplant after systemic chemotherapy, and they had a 10-year survival of 50%,” he emphasized.

However, Dr. Sapisochin acknowledged the biggest problem transplant surgeons face is that there are not enough donor organs.

One solution is living donor liver transplantation. “Given that this is an unlimited source, you can utilize this as extended criteria and it adds another graft to the system,” he explained.

“We have a protocol for living donor liver transplantations for patients with colorectal liver metastasis,” Dr. Sapisochin said. “We’ve done seven cases so far with pretty good outcomes. One patient, unfortunately, passed away 39 months after transplant with lung metastases, but the rest are alive with no recurrence.”*
 

More available organs?

R. Mark Ghobrial, MD, PhD, director of the J.C. Walter Jr. Transplant Center at Houston Methodist Hospital, said that, 5 years ago, he was very cautious about liver transplantation for intrahepatic CCA.

He pointed out that, although transplantation for hepatocellular cancer was being done in the 1990s, the results were so poor that a moratorium was placed on the practice. “But now liver transplantation has become the definitive therapy for hepatocellular cancer, and intrahepatic cholangiocarcinoma is going the same way,” he said.

Dr. Ghobrial reiterated that one of the issues in transplantation for oncology patients is the limited supply of available organs, but he believes the landscape for liver transplantation has changed, resulting in more available organs. One factor is that hepatitis C has become curable with the advent of new therapies, and hence, the need for transplantation for patients with this disease has plummeted.

“I’ve done about maybe 800 transplants in the last 5 years. I’ve only transplanted two patients with hepatitis C,” he said. “Now we are doing more transplants for alcoholic liver disease and cancer.”

Improvements in technology are also allowing for more livers to become useable, he pointed out. One example is normothermic machine perfusion, which has entered the clinical arena in the last decade. The technique has shown promising results in improving the quality of marginal organs and increasing the pool of liver grafts.

Another factor that has increased the number of livers available for transplantation is the move to accept organs from circulatory death donors, as well as donations after brain death. “Our transplantation was about 4% of donors after cardiac death, but today this has gone up to almost 16% or 20% of the livers,” Dr. Ghobrial said. “In some centers this has gone up to about 50%.

“Liver transplantation for intrahepatic cholangiocarcinoma and colorectal cancer metastases has come of age for selected patients,” he said.

More caution needed

However, another expert urged some caution, warning that live donation carries risk. Yuman Fong, MD, a surgical oncologist with City of Hope National Medical Center, Duarte, Calif., said that around “1 in 600 live donors die from donation. That is a healthy person dying. This is not a small issue.”

He pointed out that if the criteria for transplant is greatly liberalized, the 5-year survival will not be as high as demonstrated in clinical trials.

Writing about the issue in a recent editorial, Dr. Fong pointed out that cadaveric livers for transplant remain a finite resource and that more than 1,000 patients still die every year on the waiting list for a transplant.

A more reasonable approach would be to advocate for this type of program in regions of the world where cadaveric livers are more plentiful or centers with established living donor transplant programs.

“For us to develop this resource and safeguard patients, family organ donors, and resources, we need to develop what are the best inclusion criteria,” Dr. Fong said. “We have to optimize use of all cadaveric organs and determine if we are willing to transplant borderline organs.”
 

Ethics of transplanting

Ethicist Arthur L. Caplan, PhD, the Drs. William F. and Virginia Connolly Mitty Professor of Bioethics at New York University, said this is an interesting development in the field of liver transplantation. “There have been attempts in the past, and many did not end well, such as with Steve Jobs. But transplantation is always pushing to expand eligibility, and there has also been much success with that.”

However, Dr. Caplan emphasized the new data are innovative and experimental, which may control how many centers will be able to perform liver transplants in these cancer patient populations. “It has to be data driven as we are dealing with an exceedingly scarce source,” he said. “We know that people can do well, but it adds more stress to the supply of organs, and some patients may not do as well.”

He also emphasized that live donation is not a panacea. “Liver donation from a live donor is not the same as live donation for a kidney. It is much riskier and not that common. So not quite the same.”

The bottom line is that livers for transplantation are a scarce resource and transplant may work well in some cancer patients but not others, he emphasized. “Morally, we want to save lives, but not by adding in people who may not do well. If programs try to stretch the criteria, some may try transplants with more marginal organs.”

Dr. Sapisochin has disclosed relationships with Bayer, Roche, Novartis, Integra, AstraZeneca, Chiesi, Evidera, and Stryker. Dr. Ghobrial reported no relevant financial relationships. Dr. Fong has reported being a scientific consultant for Medtronic and Johnson & Johnson and receiving royalties from Merck and Imugene. Dr. Caplan writes a regular column on ethics for Medscape.

Liver transplant is an effective therapy for patients with primary liver cancer, and outcomes after transplantation are often superior to surgical resection. But the pool of potential patients is increasing, as transplantation is now emerging as an attractive option for select patients with nonresectable colorectal cancer (CRC) liver metastases, as well as those with intrahepatic cholangiocarcinoma (CCA).

Experts in the field highlighted some of the current challenges and opportunities in transplant oncology during a special session at the ASCO Gastrointestinal Cancers Symposium.

BOSTON – Noninvasive tests performed in midlife may help identify people who are at risk of late-onset epilepsy, a new study suggests. New data from the Framingham Heart Study show those who scored better on a neurocognitive test that measures executive function were 75% less likely to develop late-onset epilepsy.

An analysis of MRI revealed that those with higher cortical volumes also had a lower risk of epilepsy later in life, while those with higher white matter hyperintensities had an increased risk.

The study could help identify at-risk individuals years before symptoms of epilepsy appear.

“We present possible markers that could potentially identify patients at risk for developing late-onset epilepsy, even in the preclinical phase and before the clinical manifestation of conditions like stroke and dementia that are known now to be linked with the condition,” said lead investigator Maria Stefanidou, MD, assistant professor of neurology at Boston University.

The findings were presented at the 2023 annual meeting of the American Academy of Neurology.
 

Protection against late-onset epilepsy?

Hypertension and stroke are known risk factors for late-onset epilepsy. Dementia is also a known risk factor. But in about 30% of cases, the cause of epilepsy in older individuals is unknown.

For this study, investigators analyzed data from the offspring cohort of the Framingham Heart Study. Participants were at least 45 years old; underwent neuropsychological evaluation and brain MRI; and had no prior history of stroke, dementia, or epilepsy. Cognitive measures included Visual Reproductions Delayed Recall, Logical Memory Delayed Recall, Similarities, Trail Making B-A (TrB-TrA), and the Hooper Visual Organization Test.

Participants also underwent an MRI to measure total cerebral brain volume, cortical gray matter volume, white matter hyperintensities, and hippocampal volume.

After a mean follow-up of 13.5 years, late-onset epilepsy was diagnosed in 31 of participants who underwent neuropsychological testing (n = 2,349) and in 27 of those who underwent MRI (n = 2,056).

Better performance on the TrB-TrA test (a measure of executive function, processing speed, and occult vascular injury) was associated with a reduced risk of late-onset epilepsy (adjusted hazard ratio, 0.25; P = .011).

The findings held even after adjusting for age, sex, educational level, and known risk factors for late-onset epilepsy, such as hypertension (aHR, 0.30; P = .0401).

Higher white matter hyperintensities, a measure of occult vascular injury, was associated with increased epilepsy risk (aHR, 1.5; P = .042) when adjusted only for age, sex, and education, but was no longer significant after adjusting for hypertension and other risk factors (aHR, 1.47; P = .065).

The analysis also revealed that participants with a higher cortical gray matter volume had a lower risk for late-onset epilepsy (aHR, 0.73; P = .001).

“There is increasing literature supporting that late-onset epilepsy may be secondary to accumulative occult cerebrovascular and neurodegenerative processes that occur during aging,” Dr. Stefanidou said. “Our findings likely reflect that a lesser degree of occult vascular brain injury in midlife may be protective against late-onset epilepsy.”

However, the epidemiological study points to association, not causation, Dr. Stefanidou cautions.

“Further studies will be needed to study our observations in the clinical setting,” she said.
 

‘Intriguing’ findings

Commenting on the findings, Joseph Sirven, MD, a neurologist at the Mayo Clinic in Jacksonville, Fla., said the findings are “intriguing,” but also raise some questions. “Late-onset epilepsy remains an issue for many and it’s common,” said Dr. Sirven, who has patients with late-onset epilepsy.

Dr. Sirven was particularly interested in the findings on white matter hyperintensities. “Hippocampal volumes have been used but not so much cortical volumes,” he said. “I would like to know more about how white matter changes suggest pathology that would explain epilepsy.”

Study funding was not disclosed. Dr. Stefanidou and Dr. Sirven report no relevant financial relationships.

BOSTON – Becker (BMD) and Duchenne muscle dystrophy (DMD) progress largely from irreversible contraction-induced injury of skeletal muscles, making the very positive interim results of an early-phase trial with a drug that prevents these injuries worth attention.

The phase 1b data in BMD, presented at the 2023 annual meeting of the American Academy of Neurology, were sufficiently promising that controlled phase 2 trials in both BMD and DMD are already enrolling, reported Joanne Donovan, MD, PhD, an adjunct professor at Boston University and chief medical officer of Edgewise Therapeutics, the company developing the drug.
 

Phase 1 study

Early phase studies are largely focused on safety, but the 6-month interim data of a 12-month study showed rapid reductions in multiple biomarkers of muscle injury, reductions in anti-inflammatory markers, proteomic changes consistent with sustained effects, and a trend for functional improvement in muscle dystrophies.

Moreover, the evidence of a clinical effect was achieved in adult patients with a North Star Ambulatory Assessment (NSAA) score of 15, signifying advanced disease. Only 12 patients were enrolled and there were no controls, but objective evidence of a favorable effect was generated by highly significant reductions in creatine kinase (CK) and fast skeletal muscle (TNNI2) troponin, which are both biomarkers commonly used to track muscular dystrophy progression.

In patients with BMD or DMD, a lack of dystrophin is a key pathogenic feature, according to Dr. Donovan. She explained that dystrophin in muscles connects contractile proteins to membranes and surrounding matrix. In the presence of dystrophin, muscle fibers support each other, but when this protein is absent, contraction causes injury.

The drug in development, currently identified as EDG-5506, is a selective fast myosin inhibitor. This agent was shown to prevent the muscle injury caused by lack of dystrophin in animal models of muscular dystrophy and is now showing the same effect in humans. Preservation of muscle is critical to preventing BMD and DMD progression according to several sets of data, according to Dr. Donovan.

For one, it has been shown that BMD or DMD patients with relatively preserved function as defined by a NSAA score above 32 have minimal muscle damage. As NSAA scores fall below 32 points, muscle mass diminishes and fat accumulates. In natural history studies of BMD, there is a 1.2-point decline in NSAA score over 5 years, and this tracks with muscle loss and not with other variables, such as patient age.

“Progression depends on the degree of muscle loss,” Dr. Donovan stated, providing the rationale for moving forward with EDG-5506.
 

Proof of concept

In experimental studies, modulation of fast myelin provided complete protection against muscle injury while preserving its contractile function, and this translated into protection against loss of function. Phase 1 studies in BMD patients and healthy controls have already provided evidence that EDG-5506 is well tolerated and safe, but the new phase 1b provides a proof of concept for its ability to inhibit muscle injury in BMD patients.

In this study, called ARCH, 12 adults 18 years of age or older with a dystrophin mutation and a BMD phenotype who could complete a 100-meter timed test were enrolled. The median age at entry was 32 years. Several patients had participated in a previous phase 1 safety study. The daily starting dose of 10 mg was increased from 10 mg to 15 mg at 2 months. The dose was increased again to 20 mg at 6 months, but the data presented by Dr. Donovan were restricted to the first 6 months.

At the interim 6-month analysis, creatine kinase was reduced by 40% and TINN2 was reduced by 84% (both P < 0.001). The significant reductions in these biomarkers and others, such as myoglobin, were mostly achieved within the first month, although further reductions were observed for some biomarkers subsequently.

The NSAA score at 6 months improved on average by about 1 point on treatment. Natural history studies of BMD predict a 1-point reduction in NSAA score over this period of time. The modest improvements from baseline in pain scores at 1 month were sustained at 6 months.

On the basis of a proteomic analysis, 125 proteins mostly associated with metabolic pathways consistent with muscle injury were found to be altered in BMD patients relative to healthy controls. The majority of these proteins, whether assessed collectively or individually, normalized after 1 to 2 months of treatment with EDG-5506 and have remained stable during follow-up to date, according to Dr. Donovan.

As in previous studies, the drug was well tolerated. The three most common treatment-emergent events were dizziness, somnolence, and headache. Each was reported by about 25% of patients, but no patient discontinued therapy as a result of adverse events.
 

Findings deemed ‘a big deal’

These data, despite the small number of patients in the study and the limited follow-up, “are a big deal,” according to Nicholas E. Johnson, MD, division chief, neuromuscular disorders, Virginia Commonwealth University, Richmond. He pointed out that there are no effective treatments currently for BMD, and the mechanism of action is plausible.

“I am excited about the potential of this treatment, although we clearly need longer follow-up and more patients evaluated on this treatment,” Dr. Johnson said. He said that clinicians with BMD patients should be aware of the phase 2 trial that is now recruiting adult subjects.

“Becker muscular dystrophy is highly disabling. As disease advances, most patients have very limited function,” said Dr. Johnson, emphasizing the urgent unmet need for an effective therapy.

BOSTON – Becker (BMD) and Duchenne muscle dystrophy (DMD) progress largely from irreversible contraction-induced injury of skeletal muscles, making the very positive interim results of an early-phase trial with a drug that prevents these injuries worth attention.

The phase 1b data in BMD, presented at the 2023 annual meeting of the American Academy of Neurology, were sufficiently promising that controlled phase 2 trials in both BMD and DMD are already enrolling, reported Joanne Donovan, MD, PhD, an adjunct professor at Boston University and chief medical officer of Edgewise Therapeutics, the company developing the drug.
 

Phase 1 study

Early phase studies are largely focused on safety, but the 6-month interim data of a 12-month study showed rapid reductions in multiple biomarkers of muscle injury, reductions in anti-inflammatory markers, proteomic changes consistent with sustained effects, and a trend for functional improvement in muscle dystrophies.

Moreover, the evidence of a clinical effect was achieved in adult patients with a North Star Ambulatory Assessment (NSAA) score of 15, signifying advanced disease. Only 12 patients were enrolled and there were no controls, but objective evidence of a favorable effect was generated by highly significant reductions in creatine kinase (CK) and fast skeletal muscle (TNNI2) troponin, which are both biomarkers commonly used to track muscular dystrophy progression.

In patients with BMD or DMD, a lack of dystrophin is a key pathogenic feature, according to Dr. Donovan. She explained that dystrophin in muscles connects contractile proteins to membranes and surrounding matrix. In the presence of dystrophin, muscle fibers support each other, but when this protein is absent, contraction causes injury.

The drug in development, currently identified as EDG-5506, is a selective fast myosin inhibitor. This agent was shown to prevent the muscle injury caused by lack of dystrophin in animal models of muscular dystrophy and is now showing the same effect in humans. Preservation of muscle is critical to preventing BMD and DMD progression according to several sets of data, according to Dr. Donovan.

For one, it has been shown that BMD or DMD patients with relatively preserved function as defined by a NSAA score above 32 have minimal muscle damage. As NSAA scores fall below 32 points, muscle mass diminishes and fat accumulates. In natural history studies of BMD, there is a 1.2-point decline in NSAA score over 5 years, and this tracks with muscle loss and not with other variables, such as patient age.

“Progression depends on the degree of muscle loss,” Dr. Donovan stated, providing the rationale for moving forward with EDG-5506.
 

Proof of concept

In experimental studies, modulation of fast myelin provided complete protection against muscle injury while preserving its contractile function, and this translated into protection against loss of function. Phase 1 studies in BMD patients and healthy controls have already provided evidence that EDG-5506 is well tolerated and safe, but the new phase 1b provides a proof of concept for its ability to inhibit muscle injury in BMD patients.

In this study, called ARCH, 12 adults 18 years of age or older with a dystrophin mutation and a BMD phenotype who could complete a 100-meter timed test were enrolled. The median age at entry was 32 years. Several patients had participated in a previous phase 1 safety study. The daily starting dose of 10 mg was increased from 10 mg to 15 mg at 2 months. The dose was increased again to 20 mg at 6 months, but the data presented by Dr. Donovan were restricted to the first 6 months.

At the interim 6-month analysis, creatine kinase was reduced by 40% and TINN2 was reduced by 84% (both P < 0.001). The significant reductions in these biomarkers and others, such as myoglobin, were mostly achieved within the first month, although further reductions were observed for some biomarkers subsequently.

The NSAA score at 6 months improved on average by about 1 point on treatment. Natural history studies of BMD predict a 1-point reduction in NSAA score over this period of time. The modest improvements from baseline in pain scores at 1 month were sustained at 6 months.

On the basis of a proteomic analysis, 125 proteins mostly associated with metabolic pathways consistent with muscle injury were found to be altered in BMD patients relative to healthy controls. The majority of these proteins, whether assessed collectively or individually, normalized after 1 to 2 months of treatment with EDG-5506 and have remained stable during follow-up to date, according to Dr. Donovan.

As in previous studies, the drug was well tolerated. The three most common treatment-emergent events were dizziness, somnolence, and headache. Each was reported by about 25% of patients, but no patient discontinued therapy as a result of adverse events.
 

Findings deemed ‘a big deal’

These data, despite the small number of patients in the study and the limited follow-up, “are a big deal,” according to Nicholas E. Johnson, MD, division chief, neuromuscular disorders, Virginia Commonwealth University, Richmond. He pointed out that there are no effective treatments currently for BMD, and the mechanism of action is plausible.

“I am excited about the potential of this treatment, although we clearly need longer follow-up and more patients evaluated on this treatment,” Dr. Johnson said. He said that clinicians with BMD patients should be aware of the phase 2 trial that is now recruiting adult subjects.

PHOENIX – When Kathy Givens walked onstage during a plenary session at the annual conference of the American Society for Laser Medicine and Surgery to reflect on her 9-month ordeal being sex trafficked in Texas more than 20 years ago, you could hear a pin drop.

“One of the scariest things about the life of sex trafficking is not knowing who’s going to be on the other side,” said Ms. Givens, who now lives in Houston. “There was some violence. There were some horrible things that happened. But you know what was really scary? When I got out. People may ask, ‘How’s that so? You escaped your trafficker. The past is behind you. Why were you afraid?’ I was afraid because I didn’t know that I had community. I didn’t know that community or that society would care about someone like me.”

She said that she found herself immobilized by fear of being shamed in society and labeled a sex trafficking victim, and wondered if she could overcome that fear and if anyone would view her as human again. Once free from her trafficker, she began a “healing journey,” which included getting married, raising four children, and re-enrolling in college with hopes of becoming a social worker. In 2020, she and her husband founded Twelve 11 Partners, an organization committed to supporting human trafficking survivors.

“I was working in the anti-trafficking field helping other survivors ... who have experienced this horrific crime,” she said. “I thought I was on my way.” But one “stain” from her sex trafficking past remained: The name of her trafficker was tattooed on her skin, “a reminder of what I’d gone through.”

Ms. Givens was eventually introduced to Paul M. Friedman, MD, the current ASLMS president and one of the nearly 90 physicians in the United States and Canada who perform tattoo removal free of charge for trafficking survivors as part of the New Beginnings: Tattoo Removal Program, a partnership between the ASLMS and the National Trafficking Sheltered Alliance (NTSA) that was formed in 2022. According to a survey that Dr. Friedman and colleagues presented at the 2022 annual ASLMS conference, an estimated 1 in 2 sex trafficking survivors have branding tattoos, and at least 1,000 survivors a year could benefit from removal of those tattoos.

“To date, 87 physicians in the U.S. and one in Canada have stepped forward to volunteer their services to be part of this program,” Dr. Friedman, who directs the Dermatology and Laser Surgery Center in Houston, said at this year’s meeting. “My goal is to double this number by the next annual conference,” he added, noting that trauma-informed training is part of the program, “to support the survivor experience during the treatment process.”

ASLMS is also working on this issue in partnership with the American Academy of Dermatology (AAD) Ad Hoc Task Force on Dermatological Resources for the Intervention and Prevention of Human Trafficking, which is headed by Boston dermatologist Shadi Kourosh, MD.

“Dermatologists are uniquely positioned to aid in efforts to assist those experiences in trafficking with our training to recognize and diagnose relevant signs on the skin and to assist patients with certain aspects of care and recovery including the treatment of the disease of scars and tattoos,” Dr. Friedman said. “Ultimately, we hope to create a database together to improve recognition of branding tattoos to aid in identifying sex trafficking victims.”

Ms. Givens, who sits on the U.S. Advisory Council on Human Trafficking, said that she was able to truly close the door on her sex trafficking past thanks to the tattoo removal Dr. Friedman performed as part of New Beginnings. “It means the world to me to know that I can now be an advocate for other individuals who have experienced human trafficking,” she told meeting attendees.

“Again, one of the scariest things is not knowing that you have community. I was scared of losing hope, but I’m standing here today. I have all the hope that I need. You have the power to change lives.”

WASHINGTON –  Posttraumatic stress disorder (PTSD) is strongly linked to disordered eating, which in turn, impedes treatment for the anxiety disorder in new findings that underscore the need for better screening of eating disorder impairment (EDI).

“Eating-related and body-image concerns may be more prevalent than we think, and if not considered, these concerns can make psychotherapy treatment less effective,” study author Nick Powers, a doctoral student in clinical psychology, La Salle University, Philadelphia, told this news organization.

The findings were presented as part of the Anxiety and Depression Association of America Anxiety & Depression conference.
 

Common bedfellows

Although many patients with PTSD also have an eating disorder, they are not always properly assessed for eating pathology and related functional impairment.

Some therapists don’t feel adequately equipped to target eating-related concerns in these patients and so may refer them to other providers. This, said Mr. Powers, can prolong symptoms and further distress patients.

Mr. Powers noted childhood physical or sexual abuse may affect eating patterns in patients with PTSD. “The evidence suggests these types of trauma exposure can be risk factors for the development of an eating disorder.”

Undiagnosed eating pathology may exacerbate functional impairment from PTSD and weaken the impact of evidence-based treatment.

Such patients are challenging to treat as they may not have the requisite skills to fully engage in exposure therapy, an evidence-based approach to treat PTSD, said Mr. Powers.

To determine whether PTSD would be significantly linked to greater eating disorder impairment (EDI) compared with other anxiety-related diagnoses and whether this would impair treatment, investigators studied 748 patients with an anxiety disorder who were attending a cognitive behavioral therapy (CBT) clinic. Anxiety disorders included PTSD, obsessive-compulsive disorder (OCD), social anxiety, and panic disorder.

Participants completed the 16-item Clinical Impairment Assessment (CIA) questionnaire, which includes questions about eating habits and feelings about food, body shape, and weight over the previous 4 weeks. Participants also reported anxiety symptom severity at the beginning, during, and end of treatment.
 

Need for better screening

Results showed that compared with those who had other anxiety disorders, patients with PTSD were three times more likely to have disordered eating (odds ratio [OR], 3.06; 95% confidence interval [CI], 1.47-6.37; P = .003).

In addition, higher baseline CIA scores predicted poorer PTSD treatment outcome (beta = –1.4; 95% CI, –1.67 to –1.10; P < .01).

“Having higher baseline CIA scores meant that patients’ PTSD symptoms did not remit as strongly compared to those with lower scores,” said Mr. Powers.

Patients with both PTSD and an eating disorder may have difficulty with regulating emotions and tolerating distress, he said.

“They may use binge eating, purging, or food restriction as strategies to regulate emotions. These behaviors may allow patients to become numb to or avoid heightened emotions that come from having PTSD and an eating disorder.”

Prior research linked perfectionism tendencies to poorer response to PTSD treatment. Those with an eating disorder may share similar tendencies, said Mr. Powers.

“If someone is consistently thinking negatively about their eating or body to the point where it interrupts their functioning, they may not be as likely to fully engage with PTSD treatment,” he said.

Ideally, clinicians would screen all patients with PTSD for an eating disorder, said Mr. Powers. “If screening instruments aren’t feasible or available, even just inquiring about body image or history of maladaptive eating behaviors can be helpful.”

He added this could open up a conversation about a traumatic event in the patient’s past.
 

Confirmatory research

Commenting on the study, Karen S. Mitchell, PhD, clinical research psychologist, National Center for PTSD, VA Boston Healthcare System, and associate professor in psychiatry, Boston University, said she was “excited” to see this research.

Boston University

“Very few studies have examined the impact of baseline eating disorder symptoms on PTSD treatment outcomes or vice versa,” she said.

The study findings “add to the small but growing body of evidence suggesting that comorbid PTSD and eating disorder symptoms can impact recovery from each disorder,” she said.

She noted the importance of assessing comorbidity in patients presenting for treatment and of addressing comorbidity in both eating disorders and PTSD treatment. “But we need more research on how best to do this.”

Mr. Powers and Dr. Mitchell have reported no relevant financial relationships.

“They may use binge eating, purging, or food restriction as strategies to regulate emotions. These behaviors may allow patients to become numb to or avoid heightened emotions that come from having PTSD and an eating disorder.”

Prior research linked perfectionism tendencies to poorer response to PTSD treatment. Those with an eating disorder may share similar tendencies, said Mr. Powers.

“If someone is consistently thinking negatively about their eating or body to the point where it interrupts their functioning, they may not be as likely to fully engage with PTSD treatment,” he said.

Ideally, clinicians would screen all patients with PTSD for an eating disorder, said Mr. Powers. “If screening instruments aren’t feasible or available, even just inquiring about body image or history of maladaptive eating behaviors can be helpful.”

He added this could open up a conversation about a traumatic event in the patient’s past.
 

Confirmatory research

Commenting on the study, Karen S. Mitchell, PhD, clinical research psychologist, National Center for PTSD, VA Boston Healthcare System, and associate professor in psychiatry, Boston University, said she was “excited” to see this research.

“Very few studies have examined the impact of baseline eating disorder symptoms on PTSD treatment outcomes or vice versa,” she said.

The study findings “add to the small but growing body of evidence suggesting that comorbid PTSD and eating disorder symptoms can impact recovery from each disorder,” she said.

She noted the importance of assessing comorbidity in patients presenting for treatment and of addressing comorbidity in both eating disorders and PTSD treatment. “But we need more research on how best to do this.”

Mr. Powers and Dr. Mitchell have reported no relevant financial relationships.
