The erectile dysfunction medication Viagra could potentially be used as a treatment for Alzheimer’s disease, according to a new study published in the journal Nature Aging.

Patients who used the drug sildenafil, the generic name for Viagra, were 69% less likely to develop the disease than were nonusers.

“Sildenafil, which has been shown to significantly improve cognition and memory in preclinical models, presented as the best drug candidate,” Feixiong Cheng, PhD, the lead study author in the Cleveland Clinic’s Genomic Medicine Institute, said in a statement.

“Notably, we found that sildenafil use reduced the likelihood of Alzheimer’s in individuals with coronary artery disease, hypertension, and type 2 diabetes, all of which are comorbidities significantly associated with risk of the disease, as well as in those without,” he said.

Alzheimer’s, which is the most common form of age-related dementia, affects hundreds of millions of people worldwide. The disease is expected to affect nearly 14 million Americans by 2050. There is no approved treatment for it.

Dr. Cheng and colleagues at the Cleveland Clinic used a large gene-mapping network to analyze whether more than 1,600 Food and Drug Administration–approved drugs could work against Alzheimer’s. They gave higher scores to drugs that target both amyloid and tau proteins in the brain, which are two hallmarks of the disease. Sildenafil appeared at the top of the list.

Then the researchers used a database of health insurance claims for more than 7 million people in the U.S. to understand the relationship between sildenafil and Alzheimer’s disease outcomes. They compared sildenafil users to nonusers and found that those who used the drug were 69% less likely to have the neurodegenerative disease, even after 6 years of follow-up.

After that, the research team came up with a lab model that showed the sildenafil increased brain cell growth and targeted tau proteins. The lab model could indicate how the drug influences disease-related brain changes.

But Dr. Cheng cautioned against drawing strong conclusions. The study doesn’t demonstrate a causal relationship between sildenafil and Alzheimer’s disease. Researchers will need to conduct clinical trials with a placebo control to see how well the drug works.

Other researchers said the findings offer a new avenue for research but don’t yet provide solid answers.

“Being able to repurpose a drug already licensed for health conditions could help speed up the drug discovery process and bring about life-changing dementia treatments sooner,” Susan Kohlhaas, PhD, director of research at Alzheimer’s Research UK, told the Science Media Centre.

“Importantly, this research doesn’t prove that sildenafil is responsible for reducing dementia risk, or that it slows or stops the disease,” she continued. “If you want to discuss any treatments you are receiving, the first port of call is to speak to your doctor.”

And doctors won’t likely recommend it as a treatment just yet either.

“While these data are interesting scientifically, based on this study, I would not rush out to start taking sildenafil as a prevention for Alzheimer’s disease,” Tara Spires-Jones, PhD, deputy director of the Centre for Discovery Brain Sciences at the University of Edinburgh, told the Science Media Centre.

Genomic profiling improves outcomes for patients with metastatic breast cancer as long as the alteration-drug match has good clinical trial evidence supporting its use, a new pooled analysis suggests.

“The message is very simple,” lead study author Fabrice Andre, MD, PhD, research director, Gustave Roussy Cancer Campus, Villejuif, France, told this news organization during a virtual press briefing. “If a genomic alteration is validated, it is useful to give targeted therapy, but if the genomic alteration is not validated, we should not give a targeted therapy.”

The study, which pooled results from phase 2 randomized trials SAFIR02-BREAST and SAFIR-P13K, was presented Dec. 7 in a virtual press briefing at the San Antonio Breast Cancer Symposium (SABCS) 2021.

The new analysis explored two key questions: Is genomic testing of a cancer effective? And how should oncologists interpret a genomic report?

A total of 1,462 patients with metastatic HER2-negative breast cancer underwent next-generation sequencing. After receiving six to eight cycles of chemotherapy, 238 patients (16%) were randomized to one of nine targeted therapies matched to the genomic alteration identified on testing or to maintenance chemotherapy.

Genomic alterations in the patients’ tumors were classified using the ESMO Scale of Actionability of Molecular Targets (ESCAT). A tier I ranking indicates that the alteration-drug match is associated with improved outcomes in clinical trials, while a tier II ranking means that the alteration-drug match is associated with antitumor activity but the magnitude of benefit remains unknown.

In an analysis of the overall trial population, Dr. Andre and colleagues found an improvement in progression-free survival in the targeted therapy group (median of 5.5 months) in comparison with the maintenance chemotherapy group (2.9 months), but the difference was not significant (P = .109).

In a subgroup of 115 patients presenting with I- or II-tier genomic alterations, median progression-free survival was 59% longer, at 9.1 months, among patients receiving targeted therapy, compared with 2.8 months in the maintenance chemotherapy group (hazard ratio, 0.41; P < .001).

In addition, the team carried out single-nucleotide polymorphism (SNP) array analyses on 926 patients. They identified 21 genes that were altered more frequently in the metastases compared with the primary tumors, and they observed that a high homologous recombination deficiency score in patients with BCRA 1 or 2 mutations was associated with a longer progression-free survival in patients treated with olaparib.

“We also identified a subset of patients who are resistant to CDK4/6 inhibitors who presented with CDK4 amplification, and this amplification is associated with overexpression,” Dr. Andre explained.

When asked whether most oncologists were using genomic profiling to tailor treatment for breast cancer patients, Dr. Andre said that multigene sequencing is now widely used.

“The issue is not so much whether we should use or not use genomics; the issue here is to force everyone to put the genomic alteration in the right context in terms of its level of evidence,” Dr. Andre told this news organization.

Oncologists may overinterpret the genomic activation identified and give a targeted therapy that is not validated, but “oncologists should not use genomic information when the target has not been previously validated in a therapeutic trial,” he added.

Virginia Kaklamani, MD, professor of medicine at the University of Texas Health Sciences Center in San Antonio, said in an interview that approximately 5 years ago, Dr. Andre was part of the first debate at the SABCS discussing whether oncologists should be conducting next-generation sequencing for their patients with breast cancer.

“At the time, [Dr.] Andre’s comment was that we should not be doing it,” recalled Dr. Kaklamani, who is also leader of the breast cancer program at the Mays Cancer Center at the University of Texas Health San Antonio MD Anderson. “At that point, I think it was clear that we did not have the data we needed to be able to use next-generation sequencing to change our clinical management.”

However, the evidence has evolved. “Based on this clinical trial, I think we now do have the data,” she said. “I think that [next-generation sequencing] is something we will be using more and more in practice and treating our patients based on [validated] genomic alterations.”

Dr. Andre has received grants or advisory board/speaker honoraria from Daiichi Sankyo, Roche, Pfizer, AstraZeneca, Lily, and Novartis. Dr. Kaklamani has served as a consultant for Puma, AstraZeneca, Athenex, and Immunomedics, has received research funding from Eisai, and has served as a speaker for Pfizer, Celgene, Genentech, and Genomic Health, among other companies.

People with thyroid cancer treated with thyroidectomy have as much as a 40% increased risk of developing type 2 diabetes, regardless of their age, with the elevated risk observed with low as well as high doses of postoperative levothyroxine, new research shows.

“This is the first population-based study to demonstrate an elevated risk of type 2 diabetes in postthyroidectomy patients with thyroid cancer, compared with that in matched controls,” wrote the authors of the research, published recently in the Journal of Clinical Endocrinology & Metabolism.

“Notably, there was a U-shaped relationship between postoperative levothyroxine dosage, a surrogate marker of TSH suppression, and the risk of type 2 diabetes,” said Hye Jin Yoo, MD, of the division of endocrinology and metabolism, Korea University College of Medicine, Seoul, and colleagues.

While other studies have linked thyroidectomy for thyroid cancer with an elevated risk for other metabolic conditions, including coronary heart disease and ischemic stroke, the relatively high diabetes risk is unexpected, said Tyler Drake, MD, an endocrinologist with the Minneapolis VA Health Care System.

“A 40% increased risk of diabetes is a big surprise,” he said in an interview.

“Diabetes is very common, with about one in 10 U.S. adults having type 2 diabetes, but a 40% increased risk in thyroid cancer patients is higher than I see in my clinical practice. [However], it is important to note that the [highest] risk was predominantly among the groups on the lowest and highest doses of levothyroxine,” said Dr. Drake, assistant professor of medicine at the University of Minnesota, Minneapolis.
 

U-shaped relationship between levothyroxine dose and diabetes risk

The findings are from a study of 36,377 patients with thyroid cancer in the National Health Insurance Service (NHIS) database in Korea who had undergone a thyroidectomy between 2004 and 2013.

The patients were matched 1:1 with controls who had nonthyroid cancers. Their mean age was 46.6 years, about 30% were male, and their mean body mass index was 23.8 kg/m².

Over a mean follow-up of 6.6 years, the patients with thyroid cancer had a significantly higher risk of developing type 2 diabetes, at a rate of 47.5% (10,812) compared with 36.9% (9414; HR, 1.43; P < .001) in the control group, after adjustment for factors such as age, sex, BMI, smoking, drinking, systolic blood pressure, and fasting glucose.

The risk of type 2 diabetes among those with thyroid cancer was higher among the 83.2% of patients who underwent a total thyroidectomy compared with the 16.8% who had a unilateral lobectomy (HR, 1.06; P < .001).

In addition, those with thyroid cancer who received the lowest as well as highest dosages of levothyroxine had significantly higher risks of type 2 diabetes compared with controls (HR, 1.50 and 1.39, respectively; both P < .001).

A closer look at quartiles of levothyroxine dosing showed the first (lowest) quartile (defined as a mean levothyroxine dosage of < 101 mcg/day) was associated with an increased risk of type 2 diabetes compared with the second quartile group (101-127 mcg/day; HR, 1.45), as was the fourth quartile (≥ 150 mcg/day; HR, 1.37), while a decreased risk of type 2 diabetes was observed in the third quartile group (128-149 mcg/day versus the second quartile group; HR, 0.91).

“This result suggests a U-shaped relationship between the mean levothyroxine dosage and risk of type 2 diabetes in postthyroidectomy patients with thyroid cancer,” the authors said.

However, “consistent with previous studies, the present study showed that the highest risk of type 2 diabetes was observed in patients with thyroid cancer who were treated with the lowest mean dosage of levothyroxine,” they noted.

“This result suggests that inadequate supplementation of thyroid hormones may worsen glucose metabolism and should therefore be avoided.”
 

Potential mechanisms

Abnormal thyroid function, including hypo- and hyperthyroidism, following thyroidectomy and subsequent treatment with levothyroxine, is known to have potentially detrimental effects on glucose regulation among patients with thyroid cancer.

The potential mechanisms linking hypothyroidism with diabetes specifically include the possibility that insulin becomes unable to promote the utilization of glucose by muscles and adipose tissue. However, thyroid hormone replacement has been associated with a normalization of insulin sensitivity, the authors noted.

Meanwhile, glucose intolerance is common among patients with hyperthyroidism, largely due to an increase in hepatic glucose production, and likewise, the normalization of thyroid levels among those treated with methimazole has been linked to normalization of glucose and lipid metabolism alterations.

Dr. Drake noted that an important study limitation is that patients were analyzed based on their levothyroxine dose and not their TSH values, which the authors explain was due to the unavailability of the TSH values. 

“By looking at levothyroxine doses, and not TSH values, it is possible some patients were being improperly treated with either too much or too little levothyroxine,” Dr. Drake noted.
 

Control group should have had hypothyroidism

The findings nevertheless shed light on the risk of diabetes following thyroidectomy for thyroid cancer, Anupam Kotwal, MD, commented on the study.

“This study is significant because it addresses an important topic exploring the link between thyroid dysfunction and metabolic disease, in this case ... hypothyroidism, due to surgery for thyroid cancer and type 2 diabetes,” Dr. Kotwal, assistant professor of medicine in the division of diabetes, endocrinology & metabolism at the University of Nebraska Medical Center, Omaha, said in an interview.

In terms of other limitations, Dr. Kotwal noted that the controls did not have hypothyroidism; therefore, “from this study, it is impossible to confirm whether hypothyroidism from any cause would be associated with higher incidence of diabetes or if it is specific to thyroid surgery for thyroid cancer.

“It would have been useful to have a control group of autoimmune primary hypothyroidism to evaluate the rate of diabetes during a similar follow-up duration,” Dr. Kotwal said.

“Hence, cohort studies with more granular data such as degree of TSH suppression and having a control group of hypothyroid patients due to autoimmune thyroid disease are needed to better understand this risk.”

Dr. Kotwal and Dr. Drake have reported no relevant financial relationships.

Control group should have had hypothyroidism

The findings nevertheless shed light on the risk of diabetes following thyroidectomy for thyroid cancer, Anupam Kotwal, MD, commented on the study.

“This study is significant because it addresses an important topic exploring the link between thyroid dysfunction and metabolic disease, in this case ... hypothyroidism, due to surgery for thyroid cancer and type 2 diabetes,” Dr. Kotwal, assistant professor of medicine in the division of diabetes, endocrinology & metabolism at the University of Nebraska Medical Center, Omaha, said in an interview.

In terms of other limitations, Dr. Kotwal noted that the controls did not have hypothyroidism; therefore, “from this study, it is impossible to confirm whether hypothyroidism from any cause would be associated with higher incidence of diabetes or if it is specific to thyroid surgery for thyroid cancer.

“It would have been useful to have a control group of autoimmune primary hypothyroidism to evaluate the rate of diabetes during a similar follow-up duration,” Dr. Kotwal said.

“Hence, cohort studies with more granular data such as degree of TSH suppression and having a control group of hypothyroid patients due to autoimmune thyroid disease are needed to better understand this risk.”

Dr. Kotwal and Dr. Drake have reported no relevant financial relationships.

People with thyroid cancer treated with thyroidectomy have as much as a 40% increased risk of developing type 2 diabetes, regardless of their age, with the elevated risk observed with low as well as high doses of postoperative levothyroxine, new research shows.

“This is the first population-based study to demonstrate an elevated risk of type 2 diabetes in postthyroidectomy patients with thyroid cancer, compared with that in matched controls,” wrote the authors of the research, published recently in the Journal of Clinical Endocrinology & Metabolism.

“Notably, there was a U-shaped relationship between postoperative levothyroxine dosage, a surrogate marker of TSH suppression, and the risk of type 2 diabetes,” said Hye Jin Yoo, MD, of the division of endocrinology and metabolism, Korea University College of Medicine, Seoul, and colleagues.

While other studies have linked thyroidectomy for thyroid cancer with an elevated risk for other metabolic conditions, including coronary heart disease and ischemic stroke, the relatively high diabetes risk is unexpected, said Tyler Drake, MD, an endocrinologist with the Minneapolis VA Health Care System.

“A 40% increased risk of diabetes is a big surprise,” he said in an interview.

“Diabetes is very common, with about one in 10 U.S. adults having type 2 diabetes, but a 40% increased risk in thyroid cancer patients is higher than I see in my clinical practice. [However], it is important to note that the [highest] risk was predominantly among the groups on the lowest and highest doses of levothyroxine,” said Dr. Drake, assistant professor of medicine at the University of Minnesota, Minneapolis.
 

U-shaped relationship between levothyroxine dose and diabetes risk

The findings are from a study of 36,377 patients with thyroid cancer in the National Health Insurance Service (NHIS) database in Korea who had undergone a thyroidectomy between 2004 and 2013.

The patients were matched 1:1 with controls who had nonthyroid cancers. Their mean age was 46.6 years, about 30% were male, and their mean body mass index was 23.8 kg/m².

Over a mean follow-up of 6.6 years, the patients with thyroid cancer had a significantly higher risk of developing type 2 diabetes, at a rate of 47.5% (10,812) compared with 36.9% (9414; HR, 1.43; P < .001) in the control group, after adjustment for factors such as age, sex, BMI, smoking, drinking, systolic blood pressure, and fasting glucose.

The risk of type 2 diabetes among those with thyroid cancer was higher among the 83.2% of patients who underwent a total thyroidectomy compared with the 16.8% who had a unilateral lobectomy (HR, 1.06; P < .001).

In addition, those with thyroid cancer who received the lowest as well as highest dosages of levothyroxine had significantly higher risks of type 2 diabetes compared with controls (HR, 1.50 and 1.39, respectively; both P < .001).

A closer look at quartiles of levothyroxine dosing showed the first (lowest) quartile (defined as a mean levothyroxine dosage of < 101 mcg/day) was associated with an increased risk of type 2 diabetes compared with the second quartile group (101-127 mcg/day; HR, 1.45), as was the fourth quartile (≥ 150 mcg/day; HR, 1.37), while a decreased risk of type 2 diabetes was observed in the third quartile group (128-149 mcg/day versus the second quartile group; HR, 0.91).

“This result suggests a U-shaped relationship between the mean levothyroxine dosage and risk of type 2 diabetes in postthyroidectomy patients with thyroid cancer,” the authors said.

However, “consistent with previous studies, the present study showed that the highest risk of type 2 diabetes was observed in patients with thyroid cancer who were treated with the lowest mean dosage of levothyroxine,” they noted.

“This result suggests that inadequate supplementation of thyroid hormones may worsen glucose metabolism and should therefore be avoided.”
 

Potential mechanisms

Abnormal thyroid function, including hypo- and hyperthyroidism, following thyroidectomy and subsequent treatment with levothyroxine, is known to have potentially detrimental effects on glucose regulation among patients with thyroid cancer.

The potential mechanisms linking hypothyroidism with diabetes specifically include the possibility that insulin becomes unable to promote the utilization of glucose by muscles and adipose tissue. However, thyroid hormone replacement has been associated with a normalization of insulin sensitivity, the authors noted.

Meanwhile, glucose intolerance is common among patients with hyperthyroidism, largely due to an increase in hepatic glucose production, and likewise, the normalization of thyroid levels among those treated with methimazole has been linked to normalization of glucose and lipid metabolism alterations.

Dr. Drake noted that an important study limitation is that patients were analyzed based on their levothyroxine dose and not their TSH values, which the authors explain was due to the unavailability of the TSH values. 

“By looking at levothyroxine doses, and not TSH values, it is possible some patients were being improperly treated with either too much or too little levothyroxine,” Dr. Drake noted.

In 2011, the Mayo Clinic began surveying physicians about burnout and found 45% of physicians experienced at least one symptom, such as emotional exhaustion, finding work no longer meaningful, feelings of ineffectiveness, and depersonalizing patients. Associated manifestations can range from headache and insomnia to impaired memory and decreased attention.

Fast forward 10 years to the Medscape National Physician Burnout and Suicide Report, which found that a similar number of physicians (42%) feel burned out. The COVID-19 pandemic only added insult to injury. A Medscape survey that included nearly 5,000 U.S. physicians revealed that about two-thirds (64%) of them reported burnout had intensified during the crisis.

These elevated numbers are being labeled as “a public health crisis” for the impact widespread physician burnout could have on the health of the doctor and patient safety. The relatively consistent levels across the decade seem to suggest that, if health organizations are attempting to improve physician well-being, it doesn’t appear to be working, forcing doctors to find solutions for themselves.

Jill Wener, MD, considers herself part of the 45% burned out 10 years ago. She was working as an internist at Rush University Medical Center in Chicago, but the “existential reality of being a doctor in this world” was wearing on her. “Staying up with the literature, knowing that every day you’re going to go into work without knowing what you’re going to find, threats of lawsuits, the pressure of perfectionism,” Dr. Wener told this news organization. “By the time I hit burnout, everything made me feel like the world was crashing down on me.”

When Dr. Wener encountered someone who meditated twice a day, she was intrigued, even though the self-described “most Type-A, inside-the-box, nonspiritual type, anxious, linear-path doctor” didn’t think people like her could meditate. Dr. Wener is not alone in her hesitation to explore meditation as a means to help prevent burnout because the causes of burnout are primarily linked to external rather than internal factors. Issues including a loss of autonomy, the burden and distraction of electronic health records, and the intense pressure to comply with rules from the government are not things mindfulness can fix. 

And because the sources of burnout are primarily environmental and inherent to the current medical system, the suggestion that physicians need to fix themselves with meditation can come as a slap in the face. However, when up against a system slow to change, mindfulness can provide physicians access to the one thing they can control: How they perceive and react to what’s in front of them.

At the recommendation of an acquaintance, Dr. Wener enrolled in a Vedic Meditation (also known as Conscious Health Meditation) course taught by Light Watkins, a well-known traveling instructor, author, and speaker. By the second meeting she was successfully practicing 20 minutes twice a day. This form of mediation traces its roots to the Vedas, ancient Indian texts (also the foundation for yoga), and uses a mantra to settle the mind, transitioning to an awake state of inner contentment. 

Three weeks later, Dr. Wener’s daily crying jags ended as did her propensity for road rage. “I felt like I was on the cusp of something life-changing, I just didn’t understand it,” she recalled. “But I knew I was never going to give it up.”
 

Defining mindfulness

“Mindfulness is being able to be present in the moment that you’re in with acceptance of what it is and without judging it,” said Donna Rockwell, PsyD, a leading mindfulness meditation teacher. The practice of mindfulness is really meditation. Dr. Rockwell explained that the noise of our mind is most often focused on either the past or the future. “We’re either bemoaning something that happened earlier or we’re catastrophizing the future,” she said, which prevents us from being present in the moment. 

Meditation allows you to notice when your mind has drifted from the present moment into the past or future. “You gently notice it, label it with a lot of self-compassion, and then bring your mind back by focusing on your breath – going out, going in – and the incoming stimuli through your five senses,” said Dr. Rockwell. “When you’re doing that, you can’t be in the past or future.”

Dr. Rockwell also pointed out that we constantly categorize incoming data of the moment as either “good for me or bad for me,” which gets in the way of simply being present for what you’re facing. “When you’re more fully present, you become more skillful and able to do what this moment is asking of you,” she said. Being mindful allows us to better navigate incoming stimuli, which could be a “code blue” in the ED or a patient who needs another 2 minutes during an office visit. 

When Dr. Wener was burned out, she felt unable to adapt whenever something unexpected happened. “When you have no emotional reserves, everything feels like a big deal,” she said. “The meditation gave me what we call adaptation energy; it filled up my tank and kept me from feeling like I was going to lose it at 10 o’clock in the morning.”

Dr. Rockwell explained burnout as an overactive fight or flight response activated by the amygdala. It starts pumping cortisol, our pupils dilate, and our pores open. The prefrontal cortex is offline when we’re experiencing this physiological response because they both can’t be operational at the same time. “When we’re constantly in a ‘fight or flight’ response and don’t have any access to our prefrontal cortex, we are coming from a brain that is pumping cortisol and that leads to burnout,” said Dr. Rockwell.

“Any fight or flight response leaves a mark on your body,” Dr. Wener echoed. “When we go into our state of deep rest in the meditation practice, which is two to five times more restful than sleep, it heals those stress scars.”
 

Making time for mindfulness

Prescribing mindfulness for physicians is not new. Molecular biologist Jon Kabat-Zinn, PhD, developed Mindfulness-Based Stress Reduction (MBSR) in 1979, a practice that incorporates mindfulness exercises to help people become familiar with their behavior patterns in stressful situations. Thus, instead of reacting, they can respond with a clearer understanding of the circumstance. Dr. Kabat-Zinn initially targeted people with chronic health problems to help them cope with the effects of pain and the condition of their illness, but it has expanded to anyone experiencing challenges in their life, including physicians. A standard MBSR course runs 8 weeks, making it a commitment for most people. 

Mindfulness training requires that physicians use what they already have so little of: time.

Dr. Wener was able to take a sabbatical, embarking on a 3-month trip to India to immerse herself in the study of Vedic Meditation. Upon her return, Dr. Wener took a position at Emory University, Atlanta, and has launched a number of CME-accredited meditation courses and retreats. Unlike Dr. Kabat-Zinn, her programs are by physicians and for physicians. She also created an online version of the meditation course to make it more accessible. 

For these reasons, Kara Pepper, MD, an internist in outpatient primary care in Atlanta, was drawn to the meditation course. Dr. Pepper was 7 years into practice when she burned out. “The program dovetailed into my burnout recovery,” she said. “It allowed me space to separate myself from the thoughts I was having about work and just recognize them as just that – as thoughts.”

In the course, Dr. Wener teaches the REST Technique, which she says is different than mindfulness in that she encourages the mind to run rampant. “Trying to control the mind can feel very uncomfortable because we always have thoughts,” she says. “We can’t tell the mind to stop thinking just like we can’t tell the heart to stop beating.” Dr. Wener said the REST Technique lets “the mind swim downstream,” allowing the brain to go into a deep state of rest and start to heal from the scars caused by stress. 

Dr. Pepper said the self-paced online course gave her all the tools she needed, and it was pragmatic and evidence based. “I didn’t feel ‘woo’ or like another gimmick,” she said. Pepper, who continues to practice medicine, became a life coach in 2019 to teach others the skills she uses daily. 
 

An integrated strategy

Dr. Wener acknowledges that meditation is not the panacea for everyone’s burnout, which data support. In a review published in The American Journal of Medicine in 2019, Scott Yates, MD, MBA, from the Center for Executive Medicine in Plano, Tex., found that physicians who had adopted mediation and mindfulness training to decrease anxiety and perceived work stress only experienced modest benefits. In fact, Dr. Yates claims that there’s little data to suggest the long-term benefit of any particular stress management intervention in the prevention of burnout symptoms. 

“The often-repeated goals of the Triple Aim [enhancing patient experience, improving population health, and reducing costs] may be unreachable until we recognize and address burnout in health care providers,” Dr. Yates wrote. He recommends adding a fourth goal to specifically address physician wellness, which certainly could include mindfulness training and meditation.

Burnout coach, trainer, and consultant Dike Drummond, MD, also professes that physician wellness must be added as the key fourth ingredient to improving health care. “Burnout is a dilemma, a balancing act,” he said. “It takes an integrated strategy.” The CEO and founder of TheHappyMD.com, Dr. Drummond’s integrated strategy to stop physician burnout has been taught to more than 40,000 physicians in 175 organizations, and one element of that strategy can be mindfulness training. 

Dr. Drummond said he doesn’t use the word meditation “because that scares most people”; it takes a commitment and isn’t accessible for a lot of doctors. Instead, he coaches doctors to use a ‘single-breath’ technique to help them reset multiple times throughout the day. “I teach people how to breathe up to the top of their head and then down to the bottom of their feet,” Dr. Drummond said. He calls it the Squeegee Breath Technique because when they exhale, they “wipe away” anything that doesn’t need to be there right now. “If you happen to have a mindfulness practice like meditation, they work synergistically because the calmness you feel in your mediation is available to you at the bottom of these releasing breaths.”

Various studies and surveys provide great detail as to the “why” of physician burnout. And while mindfulness is not the sole answer, it’s something physicians can explore for themselves while health care as an industry looks for a more comprehensive solution. 

“It’s not rocket science,” Dr. Drummond insisted. “You want a different result? You’re not satisfied with the way things are now and you want to feel different? You absolutely must do something different.”

Molecular biologist Jon Kabat-Zinn, PhD, developed Mindfulness-Based Stress Reduction (MBSR) in 1979, a practice that incorporates mindfulness exercises to help people become familiar with their behavior patterns in stressful situations. Thus, instead of reacting, they can respond with a clearer understanding of the circumstance. Dr. Kabat-Zinn initially targeted people with chronic health problems to help them cope with the effects of pain and the condition of their illness, but it has expanded to anyone experiencing challenges in their life, including physicians. A standard MBSR course runs 8 weeks, making it a commitment for most people. 

Mindfulness training requires that physicians use what they already have so little of: time.

Dr. Wener was able to take a sabbatical, embarking on a 3-month trip to India to immerse herself in the study of Vedic Meditation. Upon her return, Dr. Wener took a position at Emory University, Atlanta, and has launched a number of CME-accredited meditation courses and retreats. Unlike Dr. Kabat-Zinn, her programs are by physicians and for physicians. She also created an online version of the meditation course to make it more accessible. 

For these reasons, Kara Pepper, MD, an internist in outpatient primary care in Atlanta, was drawn to the meditation course. Dr. Pepper was 7 years into practice when she burned out. “The program dovetailed into my burnout recovery,” she said. “It allowed me space to separate myself from the thoughts I was having about work and just recognize them as just that – as thoughts.”

In the course, Dr. Wener teaches the REST Technique, which she says is different than mindfulness in that she encourages the mind to run rampant. “Trying to control the mind can feel very uncomfortable because we always have thoughts,” she says. “We can’t tell the mind to stop thinking just like we can’t tell the heart to stop beating.” Dr. Wener said the REST Technique lets “the mind swim downstream,” allowing the brain to go into a deep state of rest and start to heal from the scars caused by stress. 

Dr. Pepper said the self-paced online course gave her all the tools she needed, and it was pragmatic and evidence based. “I didn’t feel ‘woo’ or like another gimmick,” she said. Pepper, who continues to practice medicine, became a life coach in 2019 to teach others the skills she uses daily. 
 

An integrated strategy

Dr. Wener acknowledges that meditation is not the panacea for everyone’s burnout, which data support. In a review published in The American Journal of Medicine in 2019, Scott Yates, MD, MBA, from the Center for Executive Medicine in Plano, Tex., found that physicians who had adopted mediation and mindfulness training to decrease anxiety and perceived work stress only experienced modest benefits. In fact, Dr. Yates claims that there’s little data to suggest the long-term benefit of any particular stress management intervention in the prevention of burnout symptoms. 

“The often-repeated goals of the Triple Aim [enhancing patient experience, improving population health, and reducing costs] may be unreachable until we recognize and address burnout in health care providers,” Dr. Yates wrote. He recommends adding a fourth goal to specifically address physician wellness, which certainly could include mindfulness training and meditation.

Burnout coach, trainer, and consultant Dike Drummond, MD, also professes that physician wellness must be added as the key fourth ingredient to improving health care. “Burnout is a dilemma, a balancing act,” he said. “It takes an integrated strategy.” The CEO and founder of TheHappyMD.com, Dr. Drummond’s integrated strategy to stop physician burnout has been taught to more than 40,000 physicians in 175 organizations, and one element of that strategy can be mindfulness training. 

Dr. Drummond said he doesn’t use the word meditation “because that scares most people”; it takes a commitment and isn’t accessible for a lot of doctors. Instead, he coaches doctors to use a ‘single-breath’ technique to help them reset multiple times throughout the day. “I teach people how to breathe up to the top of their head and then down to the bottom of their feet,” Dr. Drummond said. He calls it the Squeegee Breath Technique because when they exhale, they “wipe away” anything that doesn’t need to be there right now. “If you happen to have a mindfulness practice like meditation, they work synergistically because the calmness you feel in your mediation is available to you at the bottom of these releasing breaths.”

Various studies and surveys provide great detail as to the “why” of physician burnout. And while mindfulness is not the sole answer, it’s something physicians can explore for themselves while health care as an industry looks for a more comprehensive solution. 

“It’s not rocket science,” Dr. Drummond insisted. “You want a different result? You’re not satisfied with the way things are now and you want to feel different? You absolutely must do something different.”

An updated analysis of the phase 3 CheckMate 067 trial confirms the durability of combination immunotherapy for metastatic melanoma, representing a “substantial development” in treatment, researchers say.

Nearly half the patients treated with nivolumab (Opdivo) and ipilimumab (Yervoy) were alive at 6½ years. Within this group, 77% had not received further systemic treatment after coming off the study drugs.

After a minimum follow-up of 77 months, median overall survival was 72.1 months in patients on the combination, which was more than three times longer than the 19.9 months with ipilimumab alone (hazard ratio, 0.52; 95% confidence interval, 0.43-0.64) and twice as long as the 36.9 months with nivolumab alone (HR, 0.84; 95% CI, 0.67-1.04).

The results represent the longest median overall survival seen in a phase 3 trial of advanced melanoma and are evidence of “a substantial development in the melanoma treatment landscape versus the standard median survival of 8 months a decade ago,” researchers wrote in a study published online in the Journal of Clinical Oncology.

However, lead author Jedd D. Wolchok, MD, PhD, of Memorial Sloan Kettering Cancer Center in New York, noted that the study was not designed to compare nivolumab alone with the combination. “It wasn’t powered for that. [But] what we can say is that the highest survival was in the combination group,” Dr. Wolchok told this news organization.

Dr. Wolchok cautioned that the combination therapy is not currently standard of care. “PD-1 blockade – either nivolumab or the combination – are both excellent options for care,” he added. “I can’t tell you that one of them is the standard of care because that’s too complex of a decision.”

For example, he explained, “for a patient who only has lung metastases, a single-agent PD-1 blockade might be sufficient. But if it has spread to other organs, such as the liver or bones, which are more difficult to treat, that’s when we often reach for the combination.”

Other factors that weigh into the therapeutic decision are the patient’s performance status and their so-called clinical reserve for tolerating side effects. “The likelihood of having a high-grade side effect with the combination is more than twice that of the single agent,” Dr. Wolchok said.

Until 2011, only two therapies were approved for metastatic melanoma: Chemotherapy with dacarbazine and immunotherapy with high-dose interleukin-2, neither of which was very effective at prolonging life. But patient survival changed with the advent of targeted therapies and immunotherapy. Some patients are now living for years, and as the current study shows, many have surpassed the 5-year mark and are treatment free.

The updated CheckMate 067 analysis included patients with previously untreated, unresectable stage III/IV melanoma who were randomly assigned to receive nivolumab 1 mg/kg plus ipilimumab 3 mg/kg every 3 weeks (four doses) followed by nivolumab 3 mg/kg every 2 weeks (n = 314), nivolumab 3 mg/kg every 2 weeks (n = 316), or ipilimumab 3 mg/ kg every 3 weeks (four doses; n = 315).

The authors reported the 5-year overall survival rates from the trial, published in the New England Journal of Medicine in 2019 – 52% with the combination, 44% with nivolumab alone, and 26% with ipilimumab alone.

In the updated study, overall survival at 6½ years had dropped slightly to 49%, 42%, and 23%, respectively. Patients with BRAF-mutant tumors had overall survival rates of 57%, 43%, and 25% versus 46%, 42%, and 22% in those with BRAF wild-type tumors.

Overall, median investigator-assessed progression-free survival was 11.5 months with the combination, 6.9 months with nivolumab alone, and 2.9 months with ipilimumab.

The new analysis also evaluated melanoma-specific survival (MSS), which removes competing causes of deaths from the long-term follow-up. The MSS was not reached in the combination group, and was 58.7 months in the nivolumab group and 21.9 months for ipilimumab, with MSS rates at 6.5 years of 56%, 48%, and 27%, respectively.

No new safety signals were detected, but there was more immune-mediated toxicity in the combination group, the researchers reported.

“The patients will continue to be followed,” said Dr. Wolchok, “And data are still being collected.”

The trial was supported by Bristol-Myers Squibb, the National Cancer Institute, and the National Institute for Health Research Royal Marsden–Institute of Cancer Research Biomedical Research Centre. Dr. Wolchok and coauthors reported relationships with Bristol-Myers Squibb and other drugmakers.

Apixaban appears to be safer and more effective than rivaroxaban for reducing risk of venous thromboembolism and bleeding, based on new research.

Recurrent venous thromboembolism (VTE) – a composite of pulmonary embolism and deep vein thrombosis – was the primary effectiveness outcome in the retrospective analysis of new-user data from almost 40,000 patients, which was published in Annals of Internal Medicine. Safety was evaluated through a composite of intracranial and gastrointestinal bleeding.

After a median follow-up of 102 days in the apixaban group and 105 days in the rivaroxaban group, apixaban demonstrated superiority for both primary outcomes.

These real-world findings may guide selection of initial anticoagulant therapy, reported lead author Ghadeer K. Dawwas, PhD, MSc, MBA, of the University of Pennsylvania, Philadelphia, and colleagues.

“Randomized clinical trials comparing apixaban with rivaroxaban in patients with VTE are under way (for example, COBRRA (NCT03266783),” the investigators wrote. “Until the results from these trials become available (The estimated completion date for COBRRA is December 2023.), observational studies that use existing data can provide evidence on the effectiveness and safety of these alternatives to inform clinical practice.”

In the new research, apixaban was associated with a 23% lower rate of recurrent VTE (hazard ratio, 0.77; 95% confidence interval, 0.69-0.87), including a 15% lower rate of deep vein thrombosis and a 41% lower rate of pulmonary embolism. Apixaban was associated with 40% fewer bleeding events (HR, 0.60; 95% CI, 0.53-0.69]), including a 40% lower rate of GI bleeding and a 46% lower rate of intracranial bleeding.

The study involved 37,236 patients with VTE, all of whom were diagnosed in at least one inpatient encounter and initiated direct oral anticoagulant (DOAC) therapy within 30 days, according to Optum’s deidentified Clinformatics Data Mart Database. Patients were evenly split into apixaban and rivaroxaban groups, with 18,618 individuals in each. Propensity score matching was used to minimize differences in baseline characteristics.

Apixaban was associated with an absolute reduction in recurrent VTE of 0.6% and 1.1% over 2 and 6 months, respectively, as well as reductions in bleeding of 1.1% and 1.5% over the same respective time periods.

The investigators noted that these findings were maintained in various sensitivity and subgroup analyses, including a model in which patients with VTE who had transient risk factors were compared with VTE patients exhibiting chronic risk factors.

“These findings suggest that apixaban has superior effectiveness and safety, compared with rivaroxaban and may provide guidance to clinicians and patients regarding selection of an anticoagulant for treatment of VTE,” Dr. Dawwas and colleagues concluded.

Study may have missed some nuance in possible outcomes, according to vascular surgeon

Thomas Wakefield, MD, a vascular surgeon and a professor of surgery at the University of Michigan Health Frankel Cardiovascular Center, Ann Arbor, generally agreed with the investigators’ conclusion, although he noted that DOAC selection may also be influenced by other considerations.

“The results of this study suggest that, when choosing an agent for an individual patient, apixaban does appear to have an advantage over rivaroxaban related to recurrent VTE and bleeding,” Dr. Wakefield said in an interview. “One must keep in mind that these are not the only factors that are considered when choosing an agent and these are not the only two DOACs available. For example, rivaroxaban is given once per day while apixaban is given twice per day, and rivaroxaban has been shown to be successful in the treatment of other thrombotic disorders.”

Dr. Wakefield also pointed out that the study may have missed some nuance in possible outcomes.

“The current study looked at severe outcomes that resulted in inpatient hospitalization, so the generalization to strictly outpatient treatment and less severe outcomes cannot be inferred,” he said.

Damon E. Houghton, MD, of the department of medicine and a consultant in the department of vascular medicine and hematology at Mayo Clinic, Rochester, Minn., called the study a “very nice analysis,” highlighting the large sample size.

“The results are not a reason to abandon rivaroxaban altogether, but do suggest that, when otherwise appropriate for a patient, apixaban should be the first choice,” Dr. Houghton said in a written comment. “Hopefully this analysis will encourage more payers to create financial incentives that facilitate the use of apixaban in more patients.”

Randomized trial needed, says hematologist

Colleen Edwards, MD, of the departments of medicine, hematology, and medical oncology, at the Icahn School of Medicine at Mount Sinai, New York, had a more guarded view of the findings than Dr. Wakefield and Dr. Houghton.

“[The investigators] certainly seem to be doing a lot of statistical gymnastics in this paper,” Dr. Edwards said in an interview. “They used all kinds of surrogates in place of real data that you would get from a randomized trial.”

For example, Dr. Edwards noted the use of prescription refills as a surrogate for medication adherence, and emphasized that inpatient observational data may not reflect outpatient therapy.

“Inpatients are constantly missing their medicines all the time,” she said. “They’re holding it for procedures, they’re NPO, they’re off the floor, so they missed their medicine. So it’s just a very different patient population than the outpatient population, which is where venous thromboembolism is treated now, by and large.”

Although Dr. Edwards suggested that the findings might guide treatment selection “a little bit,” she noted that insurance constraints and costs play a greater role, and ultimately concluded that a randomized trial is needed to materially alter clinical decision-making.

“I think we really have to wait for randomized trial before we abandon our other choices,” she said.

The investigators disclosed relationships with Merck, Celgene, UCB, and others. Dr. Wakefield reported awaiting disclosures. Dr. Houghton and Dr. Edwards reported no relevant conflicts of interest.

Thomas Wakefield, MD, a vascular surgeon and a professor of surgery at the University of Michigan Health Frankel Cardiovascular Center, Ann Arbor, generally agreed with the investigators’ conclusion, although he noted that DOAC selection may also be influenced by other considerations.

“The results of this study suggest that, when choosing an agent for an individual patient, apixaban does appear to have an advantage over rivaroxaban related to recurrent VTE and bleeding,” Dr. Wakefield said in an interview. “One must keep in mind that these are not the only factors that are considered when choosing an agent and these are not the only two DOACs available. For example, rivaroxaban is given once per day while apixaban is given twice per day, and rivaroxaban has been shown to be successful in the treatment of other thrombotic disorders.”

Dr. Wakefield also pointed out that the study may have missed some nuance in possible outcomes.

“The current study looked at severe outcomes that resulted in inpatient hospitalization, so the generalization to strictly outpatient treatment and less severe outcomes cannot be inferred,” he said.

Damon E. Houghton, MD, of the department of medicine and a consultant in the department of vascular medicine and hematology at Mayo Clinic, Rochester, Minn., called the study a “very nice analysis,” highlighting the large sample size.

“The results are not a reason to abandon rivaroxaban altogether, but do suggest that, when otherwise appropriate for a patient, apixaban should be the first choice,” Dr. Houghton said in a written comment. “Hopefully this analysis will encourage more payers to create financial incentives that facilitate the use of apixaban in more patients.”

Randomized trial needed, says hematologist

Colleen Edwards, MD, of the departments of medicine, hematology, and medical oncology, at the Icahn School of Medicine at Mount Sinai, New York, had a more guarded view of the findings than Dr. Wakefield and Dr. Houghton.

“[The investigators] certainly seem to be doing a lot of statistical gymnastics in this paper,” Dr. Edwards said in an interview. “They used all kinds of surrogates in place of real data that you would get from a randomized trial.”

For example, Dr. Edwards noted the use of prescription refills as a surrogate for medication adherence, and emphasized that inpatient observational data may not reflect outpatient therapy.

“Inpatients are constantly missing their medicines all the time,” she said. “They’re holding it for procedures, they’re NPO, they’re off the floor, so they missed their medicine. So it’s just a very different patient population than the outpatient population, which is where venous thromboembolism is treated now, by and large.”

Although Dr. Edwards suggested that the findings might guide treatment selection “a little bit,” she noted that insurance constraints and costs play a greater role, and ultimately concluded that a randomized trial is needed to materially alter clinical decision-making.

“I think we really have to wait for randomized trial before we abandon our other choices,” she said.

The investigators disclosed relationships with Merck, Celgene, UCB, and others. Dr. Wakefield reported awaiting disclosures. Dr. Houghton and Dr. Edwards reported no relevant conflicts of interest.

As the pandemic shows no signs of ending, primary care doctors may be reassured that delivering care via video teleconferencing can be as effective as usual in-person consultation for several common health conditions.

This was a finding of a new study published in Annals of Internal Medicine involving a review of literature on video teleconferencing (VTC) visits, which was authored by Jordan Albritton, PhD, MPH and his colleagues.

The authors found generally comparable patient outcomes as well as no differences in health care use, patient satisfaction, and quality of life when visits conducted using VTC were compared with usual care.

While VTC may work best for monitoring patients with chronic conditions, it can also be effective for acute care, said Dr. Albritton, who is a research public health analyst at RTI International in Research Triangle Park, N.C., in an interview.

The investigators analyzed 20 randomized controlled trials of at least 50 patients and acceptable risk of bias in which VTC was used either for main or adjunct care delivery. Published from 2013 to 2019, these studies looked at care for diabetes and pain management, as well as some respiratory, neurologic, and cardiovascular conditions. Studies comparing VTC with usual care that did not involve any added in-person care were more likely to favor the VTC group, the investigators found.

“We excluded conditions such as substance use disorders, maternal care, and weight management for which there was sufficient prior evidence of the benefit of VTC,” Dr. Albritton said in an interview. “But I don’t think our results would have been substantially different if we had included these other diseases. We found general evidence in the literature that VTC is effective for a broader range of conditions.”

In some cases, such as if changes in a patient’s condition triggered an automatic virtual visit, the author said he thinks VTC may lead to even greater effectiveness.

“The doctor and patient could figure out on the spot what’s going on and perhaps change the medication,” Dr. Albritton explained.

In general agreement is Julia L. Frydman, MD, assistant professor in the Brookdale Department of Geriatric and Palliative Medicine at Icahn School of Medicine at Mount Sinai in New York, who was not involved in the RTI research.

“Telemedicine has promise across many medical subspecialties, and what we need now are more studies to understand the perspectives of patients, caregivers, and clinicians as well as the impact of telemedicine on health outcomes and healthcare utilization.”

In acknowledgment of their utility, video visits are on the rise in the United States. A 2020 survey found that 22% of patients and 80% of physicians reported having participated in a video visit, three times the rate of the previous year. The authors noted that policy changes enacted to support telehealth strategies during the pandemic are expected to remain in place, and although patients are returning to in-person care, the virtual visit market will likely continue growing.
 

Increased telemedicine use by older adults

“We’ve seen an exciting expansion of telemedicine use among older adults, and we need to focus on continuing to meet their needs,” Dr. Frydman said.

In a recent study of televisits during the pandemic, Dr. Frydman’s group found a fivefold greater uptake of remote consultations by seniors – from 5% to 25%. Although in-person visits were far more common among older adults.

A specific advantage of video-based over audio-only telehealth, noted Dr. Albritton, is that physicians can directly observe patients in their home environment. Sharing that view is Deepa Iyengar, MBBS/MD,MPH, professor of family medicine at McGovern Medical School at The University of Texas Health Science Center at Houston, where, she said, “the pandemic has put VTC use into overdrive.”

According to Dr. Iyengar, who was not involved in the RTI research, the video component definitely represents value-added over phone calls. “You can pick up visual cues on video that you might not see if the patient came in and you can see what the home environment is like – whether there are a lot of loose rugs on the floor or broken or missing light bulbs,” she said in an interview.
 

‘VTC is here to stay’

In other parts of the country, doctors are finding virtual care useful – and more common. “VTC is here to stay, for sure – the horse is out of the barn,” said Cheryl L. Wilkes, MD, an internist at Northwestern Medicine and assistant professor of medicine at Northwestern University in Chicago. “The RTI study shows no harm from VTC and also shows it may even improve clinical outcomes.”

Video visits can also save patients high parking fees at clinics and spare the sick or elderly from having to hire caregivers to bring them into the office or from having to walk blocks in dangerous weather conditions, she added. “And I can do a virtual visit on the fly or at night when a relative or caregiver is home from work to be there with the patient.”

In addition to being beneficial for following up with patients with chronic diseases such as hypertension or diabetes, VTC may be able to replace some visits that have traditionally required hands-on care, said Dr. Wilkes.

She said she knows a cardiologist who has refined a process whereby a patient – say, one who may have edema – is asked to perform a maneuver via VTC and then display the result to the doctor: The doctor says, “put your leg up and press on it hard for 10 seconds and then show me what it looks like,” according to Dr. Wilkes.

The key now is to identify the best persons across specialties from neurology to rheumatology to videotape ways they’ve created to help their patients participate virtually in consults traditionally done at the office, Dr. Wilkes noted.

But some conditions will always require palpation and the use of a stethoscope, according Dr. Iyengar.

“If someone has an ulcer, I have to be able to feel it,” she said.

And while some maternity care can be given virtually – for instance, if a mother-to be develops a bad cold – hands-on obstetrical care to check the position and health of the baby obviously has to be done in person. “So VTC is definitely going to be a welcome addition but not a replacement,” Dr. Iyengar said.

Gaps in research on VTC visits

Many questions remain regarding the overall usefulness of VTC visits for certain patient groups, according to the authors.

They highlighted, for example, the dearth of data on subgroups or on underserved and vulnerable populations, with no head-to-head studies identified in their review. In addition, they found no studies examining VTC versus usual care for patients with concurrent conditions or on its effect on health equity and disparities.

“It’s now our job to understand the ongoing barriers to telemedicine access, including the digital divide and the usability of telemedicine platforms, and design interventions that overcome them,” Dr. Frydman said. “At the same time, we need to make sure we’re understanding and respecting the preferences of older adults in terms of how they access health care.”

This study was supported by the Patient-Centered Outcomes Research Institute (PCORI). Dr. Albritton is employed by RTI International, the contractor responsible for conducting the research and developing the manuscript. Several coauthors disclosed support from or contracts with PCORI. One coauthor’s spouse holds stock in private health companies. Dr. Frydman, Dr. Iyengar, and Dr. Wilkes disclosed no competing interests relevant to their comments.

Sleep apnea and other types of sleep disorders appear to elevate the risk for some types of cancer, specifically prostate cancer, more so than others. But the overall risk can be highly variable, and some sleep problems were found to be associated with a lower risk for cancer and cancer-related death, an analysis of a large observational cohort study of cardiovascular patients found.

Results of the analysis were published online in the journal Cancer Epidemiology. Investigators analyzed the presence of sleep apnea and insomnia and cancer risk in more than 8,500 patients in the Cardiovascular Health Study (CHS). “The fact that we observed certain sleep problems, like apneas, to be associated with elevated risk of some cancers but not others reflects the fact that cancer is a heterogeneous disease,” senior author Amanda Phipps, PhD, said in an interview. Dr. Phipps is an associate professor of epidemiology at the University of Washington and the Fred Hutchinson Cancer Research Center, both in Seattle.
 

Variable cancer links

The researchers assessed sleep problems in two groups in the CHS: an incident cancer group of 3,930 patients and a cancer mortality group of 4,580 patients. Within those respective groups, the investigators identified 885 first-incident cancers and 804 cancer deaths with a median follow-up of 12 and 14 years. The average age of the study population was 73 years, and 57% were women.

Sleep apnea symptoms (SAS) were associated with a lower risk for incident cancers – a 16% lower baseline risk and a 24% lower time-dependent risk. The study showed no association between cancer incidence and daytime sleepiness and apneas.

However, there was a significantly elevated risk relationship between sleep problems and prostate cancer. A time-dependent analysis of apnea showed more than double the risk (hazard ratio, 2.34), and baseline snoring carried a 69% greater risk. There was also a dose-response relationship for baseline cumulative SAS, compared with not having symptoms: an HR of 1.30 for one symptom, and 2.22 for two or more symptoms.

Risks for lymphatic or hematopoietic cancers were also associated with baseline daytime sleepiness (HR, 1.81), but not with insomnia (HR, 0.54).

With regard to cancer mortality, the study found no relationship between sleep problems and cancer death. In fact, it found an overall inverse relationship with snoring (time-dependent HR, 0.73; cumulative average HR, 0.67) and baseline apnea (HR, 0.69). Likewise, patients reporting SAS had lower risks than those having no SAS: an HR of 0.90 for one symptom and 0.75 for multiple symptoms. No relationships were found between any insomnia symptom and cancer death.

“We know the pathways that lead to prostate cancer can be very different than the pathways that lead to colorectal cancer,” Dr. Phipps said. “What we don’t yet understand is why these associations differ or what mechanisms are responsible for these cancer site-specific associations.”
 

Need for sleep assessment

The findings don’t change much for how clinicians should evaluate cancer risks in patients with sleep problems, Dr. Phipps said. “Other studies have clearly demonstrated the implications that sleep apnea has for a variety of other important health conditions – such as cardiovascular disease – so there are already plenty of good reasons for clinicians to ask their patients about their sleep and to connect patients with resources for the diagnosis and treatment of sleep apnea,” she added. “This study provides another possible reason.”

These findings provide context for future studies of the relationship between sleep problems and cancer. “But, given that sleep is something we all do and given that sleep problems are so pervasive, it’s important that we keep trying to better understand this relationship,” Dr. Phipps said.

“My hope is that future cancer studies will build in more detailed, longitudinal information on sleep patterns to help us fill current gaps in knowledge.”

Dr. Phipps has disclosed no relevant financial relationships.

The findings don’t change much for how clinicians should evaluate cancer risks in patients with sleep problems, Dr. Phipps said. “Other studies have clearly demonstrated the implications that sleep apnea has for a variety of other important health conditions – such as cardiovascular disease – so there are already plenty of good reasons for clinicians to ask their patients about their sleep and to connect patients with resources for the diagnosis and treatment of sleep apnea,” she added. “This study provides another possible reason.”

These findings provide context for future studies of the relationship between sleep problems and cancer. “But, given that sleep is something we all do and given that sleep problems are so pervasive, it’s important that we keep trying to better understand this relationship,” Dr. Phipps said.

“My hope is that future cancer studies will build in more detailed, longitudinal information on sleep patterns to help us fill current gaps in knowledge.”

Dr. Phipps has disclosed no relevant financial relationships.
