An intensive 1-year behavior therapy program aimed at changing a person’s response to food “cues” might help people with obesity lose a modest amount of weight, a randomized clinical trial suggests.

“Patients who are food-cue sensitive often feel out of control with their eating; they cannot resist food and/or cannot stop thinking about food,” said lead author Kerri N. Boutelle, PhD.

“Behavioral weight loss skills are not sufficient for these individuals,” so they designed this new approach, Dr. Boutelle, of the University of California, San Diego, explained in a press release.

The regulation of cues (ROC) intervention trains individuals to respond to their hunger and to resist eating highly craved foods (internal management), in contrast to behavioral weight loss programs that focus on counting calories (external management), Dr. Boutelle explained in an email.

The results of the Providing Adult Collaborative Interventions for Ideal Changes (PACIFIC) clinical trial, including follow-up out to 2 years, were published  in JAMA Network Open.

Patients in the behavioral weight loss therapy group or the combined ROC and behavioral weight loss therapy group lost more weight at 6 months than patients in the ROC group – but then they slowly regained weight (whereas patients in the ROC group did not).

At 24 months, the three groups had a similar modest weight loss, compared with a control group that did not lose weight.

“We believe these internal management strategies are more durable over time,” said Dr. Boutelle.  

However, two obesity experts, who helped develop the Canadian Adult Obesity Clinical Practice Guidelines, cautioned in emails that the intervention is very labor-intensive with less than 5% weight loss.

Four interventions

The trial was conducted at the Center for Healthy Eating and Activity Research at the University of California, San Diego, from December 2015 to December 2019.

Researchers randomized 271 adults with a mean BMI of 35 kg/m² to one of four interventions:

• Regulation of cues: Patients were not given a prescribed diet but instead were given skills to tolerate cravings and respond better to hunger or satiety cues.
• Behavioral weight loss therapy: Patients were advised to follow a balanced, calorie-deficit diet based on their weight and given related skills.
• Combined regulation of cues plus behavioral weight loss therapy.
• Control: Patients received information about nutrition and stress management plus mindfulness training and were encouraged to find social support.

Therapy was given as 26 group sessions, 90 minutes each, over 12 months, with 16 weekly sessions, four biweekly sessions, and six monthly booster sessions.

Participants were asked to take part in 150 minutes of moderate to high intensity exercise each week and aim for 10,000 steps per day. All patients except those in the control group received a pedometer.

The patients were a mean age of 46 years, 82% were women and 62% were White.

At the end of the 12-month intervention, mean BMI had dropped by –1.18 kg/m² in the ROC group and by –1.58 kg/m² and –1.56 kg/m² in the other two groups, compared with the control group, where BMI was virtually unchanged.

At 24 months follow-up, mean BMI was similar (roughly 33.5 kg/m²) in the ROC, the behavioral weight loss therapy, and the ROC plus behavioral weight loss therapy groups.

There was weight regain from 12 months in the latter two groups but not in the ROC group.
 

‘Nice study, but not practical’

“This is a nice study, but in no way is it practical,” Sean Wharton, MD, summarized.

“I think it may have difficulty finding its way into everyday practice,” said Dr. Wharton, adjunct professor at McMaster University, Hamilton, Ontario.

Also, “it does not compare ROC to pharmacotherapy,” he added, which is “quickly becoming the gold standard for obesity management. We have learned that adding intensive behavioral therapy – more visits and possibly a liquid diet as part of the weight management and some light group counseling – to pharmacotherapy does not add much.”

However, Dr. Wharton conceded that if an individual did not want, or could not take, pharmacotherapy and had access to ROC sessions, this might be a good option.

“The challenge will be offering this labor-intensive tool to 40% of Americans living with obesity,” he said.

The ROC intervention “is very different than a GP’s office that may see a patient two to three times/year max, with limited supports,” Dr. Wharton pointed out.

“It is labor-intensive, not reproducible in most places, and cannot be sustained forever. There is no evidence that the learning remains past the treatment interval. For example, 2 to 3 years later, are patients still adhering to ROC? Is weight still decreased or do they need to come to classes every month forever?”  
 

‘Modest weight loss, doubtful long-term benefits’

Similarly, Arya M. Sharma, MD, said: “While this [ROC] approach may be helpful for some individuals, given the rather modest weight loss achieved (despite considerable efforts and a cash incentive), the long-term clinical benefits remain doubtful.”

The weight loss of less than 5% over 24 months is “in the ballpark of other behavioral weight-loss interventions,” said Dr. Sharma, of the University of Edmonton, Alberta, and past scientific director of Obesity Canada.  

“I’m not convinced” about less weight regain, he added. “The difference between the groups is minimal. While this approach may well help individuals better deal with food cues, it does not change the underlying biology of weight regain.”

“This approach at best may help prevent future weight gain in susceptible individuals,” he speculated. “I would consider this more as a weight-stabilization than a weight-loss strategy.”
 

Next steps

Insurance doesn’t always cover weight loss with a mental health professional, Dr. Boutelle agreed. “However, there are eating disorder categories that also apply to many of our food-cue-sensitive patients, including binge eating,” she noted.

“We believe that ROC is an alternative model for weight loss that could be offered to patients who are interested or for whom behavioral weight loss has not been successful ... who are highly food-cue-responsive.”

The group is writing a manual about the ROC program to disseminate to other behavior therapists. They are also studying ROC in another clinical trial, Solutions for Hunger and Regulating Eating (SHARE). The ROC program is being offered at the UC San Diego Center for Healthy Eating and Activity Research, of which Dr. Boutelle is director.

The study was supported by grants from the National Institutes of Health. The researchers have reported no relevant financial relationships. Dr. Wharton has reported receiving honoraria and travel expenses and has participated in academic advisory boards for Novo Nordisk, Bausch Health, Eli Lilly, and Janssen. He is the medical director of a medical clinic specializing in weight management and diabetes. Dr. Sharma has reported receiving speakers bureau and consulting fees from Novo Nordisk, Bausch Pharmaceuticals, and AstraZeneca.

Many strategies widely considered “standard care” for managing spontaneous intracerebral hemorrhage (ICH) are not as effective as previously thought and are no longer recommended in updated guidelines from the American Heart Association/American Stroke Association (ASA).

Compression stockings, antiseizure medication, and steroid treatment are among the treatments with uncertain effectiveness, the writing group says.

The 2022 Guideline for the Management of Patients With Spontaneous ICH was published online  in Stroke. The 80-page document contains major changes and refinements to the 2015 guideline on ICH management.

“Advances have been made in an array of fields related to ICH, including the organization of regional health care systems, reversal of the negative effects of blood thinners, minimally invasive surgical procedures, and the underlying disease in small blood vessels,” Steven M. Greenberg, MD, PhD, chair of the guideline writing group with Harvard Medical School and Massachusetts General Hospital, both in Boston, said in a news release.

“We’ve updated sections across the board. There’s probably no area that went untouched with some tweaking and new evidence added that led to some changes in level of evidence or strength of a recommendation,” Dr. Greenberg added in an interview with this news organization.

“Each section comes with knowledge gaps, and it wasn’t hard to come up with knowledge gaps in every section,” Dr. Greenberg acknowledged.

Time-honored treatments no more?

Among the key updates are changes to some “time-honored” treatments that continue to be used with some “regularity” for patients with ICH, yet appear to confer either no benefit or harm, Dr. Greenberg said.

For example, for emergency or critical care treatment of ICH, prophylactic corticosteroids or continuous hyperosmolar therapy is not recommended, because it appears to have no benefit for outcome, while use of platelet transfusions outside the setting of emergency surgery or severe thrombocytopenia appears to worsen outcome, the authors say.

Use of graduated knee- or thigh-high compression stockings alone is not an effective prophylactic therapy for prevention of deep vein thrombosis (DVT). Instead, intermittent pneumatic compression (IPC) starting on the day of diagnosis is now recommended for DVT prophylaxis.

“This is an area where we still have a lot of exploration to do. It is unclear whether even specialized compression devices reduce the risks of deep vein thrombosis or improve the overall health of people with a brain bleed,” Dr. Greenberg said in the release.

The new guidance advises against use of antiseizure or antidepressant medications for ICH patients in whom there is no evidence of seizures or depression.

In clinical trials, antiseizure medication did not contribute to improvements in functionality or long-term seizure control, and the use of antidepressants increased the chance of bone fractures, the authors say.

The guideline also provides updated recommendations for acute reversal of anticoagulation after ICH. It highlights the use of protein complex concentrate for reversal of vitamin K antagonists, such as warfarin; idarucizumab for reversal of the thrombin inhibitor dabigatran; and andexanet alfa for reversal of factor Xa inhibitors, such as rivaroxaban, apixaban, and edoxaban.

For acute blood pressure lowering after mild to moderate ICH, treatment regimens that limit blood pressure variability and achieve smooth, sustained blood pressure control appear to reduce hematoma expansion and yield better functional outcome, the guideline says.

It also notes that minimally invasive approaches for hematoma evacuation, compared with medical management alone‚ have been shown to reduce mortality.

For patients with cerebellar hemorrhage, indications for immediate surgical evacuation with or without an external ventricular drain to reduce mortality now include larger volume (> 15 mL) in addition to previously recommended indications of neurologic deterioration, brainstem compression, and hydrocephalus, the authors note.

However, a “major knowledge gap is whether we can improve functional outcome with hematoma evacuation,” Dr. Greenberg said.
 

Multidisciplinary care

For rehabilitation after ICH, the guideline reinforces the importance of having a multidisciplinary team to develop a comprehensive plan for recovery.

Starting rehabilitation activities such as stretching and functional task training may be considered 24 to 48 hours following mild or moderate ICH. However, early aggressive mobilization within the first 24 hours has been linked to an increased risk of death within 14 days after an ICH, the guideline says.

Knowledge gaps include how soon it’s safe to return to work, drive, and participate in other social engagements. Recommendations on sexual activity and exercise levels that are safe after a stroke are also needed.

“People need additional help with these lifestyle changes, whether it’s moving around more, curbing their alcohol use, or eating healthier foods. This all happens after they leave the hospital, and we need to be sure we are empowering families with the information they may need to be properly supportive,” Dr. Greenberg says in the release.

The guideline points to the patient’s home caregiver as a “key and sometimes overlooked” member of the care team. It recommends psychosocial education, practical support, and training for the caregiver to improve the patient’s balance, activity level, and overall quality of life.
 

Opportunity for prevention?

The guideline also suggests there may be an opportunity to prevent ICH in some people through neuroimaging markers.

While neuroimaging is not routinely performed as a part of risk stratification for primary ICH risk, damage to small blood vessels that is associated with ICH may be evident on MRI that could signal future ICH risk, the guideline says.

“We added to the guidelines for the first time a section on mostly imaging markers of risk for having a first-ever hemorrhage,” Dr. Greenberg said in an interview.

“We don’t make any recommendations as to how to act on these markers because there is a knowledge gap. The hope is that we’ll see growth in our ability to predict first-ever hemorrhage and be able to do things to prevent first-ever hemorrhage,” he said.

“We believe the wide range of knowledge set forth in the new guideline will translate into meaningful improvements in ICH care,” Dr. Greenberg adds in the release.

The updated guideline has been endorsed by the American Association of Neurological Surgeons and Congress of Neurological Surgeons, the Society of Vascular and Interventional Neurology, and the Neurocritical Care Society. The American Academy of Neurology has affirmed the value of this statement as an educational tool for neurologists.

This research had no commercial funding. Dr. Greenberg has disclosed no relevant financial relationships. A complete list of disclosures for the guideline group is available with the original article.

“This is an area where we still have a lot of exploration to do. It is unclear whether even specialized compression devices reduce the risks of deep vein thrombosis or improve the overall health of people with a brain bleed,” Dr. Greenberg said in the release.

The new guidance advises against use of antiseizure or antidepressant medications for ICH patients in whom there is no evidence of seizures or depression.

In clinical trials, antiseizure medication did not contribute to improvements in functionality or long-term seizure control, and the use of antidepressants increased the chance of bone fractures, the authors say.

The guideline also provides updated recommendations for acute reversal of anticoagulation after ICH. It highlights the use of protein complex concentrate for reversal of vitamin K antagonists, such as warfarin; idarucizumab for reversal of the thrombin inhibitor dabigatran; and andexanet alfa for reversal of factor Xa inhibitors, such as rivaroxaban, apixaban, and edoxaban.

For acute blood pressure lowering after mild to moderate ICH, treatment regimens that limit blood pressure variability and achieve smooth, sustained blood pressure control appear to reduce hematoma expansion and yield better functional outcome, the guideline says.

It also notes that minimally invasive approaches for hematoma evacuation, compared with medical management alone‚ have been shown to reduce mortality.

For patients with cerebellar hemorrhage, indications for immediate surgical evacuation with or without an external ventricular drain to reduce mortality now include larger volume (> 15 mL) in addition to previously recommended indications of neurologic deterioration, brainstem compression, and hydrocephalus, the authors note.

However, a “major knowledge gap is whether we can improve functional outcome with hematoma evacuation,” Dr. Greenberg said.
 

Multidisciplinary care

For rehabilitation after ICH, the guideline reinforces the importance of having a multidisciplinary team to develop a comprehensive plan for recovery.

Starting rehabilitation activities such as stretching and functional task training may be considered 24 to 48 hours following mild or moderate ICH. However, early aggressive mobilization within the first 24 hours has been linked to an increased risk of death within 14 days after an ICH, the guideline says.

Knowledge gaps include how soon it’s safe to return to work, drive, and participate in other social engagements. Recommendations on sexual activity and exercise levels that are safe after a stroke are also needed.

“People need additional help with these lifestyle changes, whether it’s moving around more, curbing their alcohol use, or eating healthier foods. This all happens after they leave the hospital, and we need to be sure we are empowering families with the information they may need to be properly supportive,” Dr. Greenberg says in the release.

The guideline points to the patient’s home caregiver as a “key and sometimes overlooked” member of the care team. It recommends psychosocial education, practical support, and training for the caregiver to improve the patient’s balance, activity level, and overall quality of life.
 

Opportunity for prevention?

The guideline also suggests there may be an opportunity to prevent ICH in some people through neuroimaging markers.

While neuroimaging is not routinely performed as a part of risk stratification for primary ICH risk, damage to small blood vessels that is associated with ICH may be evident on MRI that could signal future ICH risk, the guideline says.

“We added to the guidelines for the first time a section on mostly imaging markers of risk for having a first-ever hemorrhage,” Dr. Greenberg said in an interview.

“We don’t make any recommendations as to how to act on these markers because there is a knowledge gap. The hope is that we’ll see growth in our ability to predict first-ever hemorrhage and be able to do things to prevent first-ever hemorrhage,” he said.

“We believe the wide range of knowledge set forth in the new guideline will translate into meaningful improvements in ICH care,” Dr. Greenberg adds in the release.

The updated guideline has been endorsed by the American Association of Neurological Surgeons and Congress of Neurological Surgeons, the Society of Vascular and Interventional Neurology, and the Neurocritical Care Society. The American Academy of Neurology has affirmed the value of this statement as an educational tool for neurologists.

This research had no commercial funding. Dr. Greenberg has disclosed no relevant financial relationships. A complete list of disclosures for the guideline group is available with the original article.

More teenagers in the United States reported cannabis use with vaping in 2019, compared with 2017, while cannabis use without vaping declined, based on annual survey data from more than 50,000 teens.

“With vaping prevalence rising so quickly among teens, getting a clearer picture of how cannabis use is shifting helps inform prevention and cessation efforts,” corresponding author Noah T. Kreski, MPH, of Columbia University, New York, said in an interview.

“In just 2 years, the most common cannabis use pattern changed from ‘occasional use without vaping’ to ‘frequent use with vaping,’ said Mx. Kreski, who uses the honorific Mx. and the pronouns they/them. “Knowing that, as well as the high overlap of cannabis vaping with nicotine use and binge drinking, adds to the urgency of reducing adolescent vaping.”

To quantify the trends in cannabis vaping, the researchers reviewed data from Monitoring the Future, an annual survey of high school students across the United States. The study population included 51,052 individuals; approximately 49% were male and 49% were non-Hispanic White. The researchers examined frequency of cannabis use, trends across demographic groups, and concurrent use of cannabis and other substances such as alcohol and tobacco. The findings were published in the journal Addiction.

Frequent cannabis use was defined as six or more times in the past 30 days; occasional use was defined as one to five times in the past 30 days.

Frequent cannabis use with vaping increased from 2.1% in 2017 to 5.4% in 2019. Occasional cannabis use with vaping also increased, though less dramatically, from less than 2% in 2017 to approximately 3.5% in 2019.

By contrast, both frequent and occasional cannabis use without vaping declined from 2017 to 2019 (from 3.8% to 2.1% and from 6.9% to 4.4%, respectively).

Overall, the prevalence of any level of cannabis use increased from 13.9% in 2017 to 15.4% in 2019. Both males and females showed a similar increase in reported frequent cannabis use with vaping of approximately 3%.

The results document that vaping cannabis has become more common than smoking alone among U.S. teens across almost all demographic groups, and across sex, race, urbanicity, and level of parent education; however, the increased was especially marked among Hispanic/Latinx teens and those of lower socioeconomic status, the researchers wrote.

The researchers also examined the associations between cannabis use with and without vaping and concurrent nicotine and alcohol use. Overall, the strongest association was between smoking or vaping nicotine and vaping cannabis; teens who smoked or vaped nicotine were 42 times more likely than nonnicotine users to report vaping cannabis in the past 30 days (adjusted odds ratio, 42.28). In addition, more occasions of binge drinking were more strongly associated with cannabis use with vaping (up to 10 times more likely), compared with cannabis use without vaping, (aORs, 4.48-10.09).

The study findings were limited by several factors, including the lack of questions on tetrahydrocannabinol (THC) or cannabidiol content of the cannabis products used, although evidence suggests that the potency of cannabis products in the United States is increasing, the researchers noted. Other limitations included the cross-sectional design, which prevents making associations about causality, and lack of data on the quantity of cannabis used; only data on frequency of use were recorded.

However, the results reflect a rise in cannabis use with vaping among teens in the United States, along with an increased risk of tobacco use, e-cigarette use, and binge drinking, the researchers said.

As cannabis legalization expands across the United States, policies are needed to deter use among adolescents, the researchers wrote. “These policies should be crafted to reduce an emphasis on criminalization in preference for public health promotion given the history of unequal application of punitive consequences of drug use for racialized minorities in the United States. As products, delivery systems, potency, and marketing proliferate within a for-profit industry, increased attention to youth trends, including investment in sustained and evidence-based prevention and intervention, is increasingly necessary.”

The take-home message for clinicians is to ask whether your patients are vaping, because the prevalence is not only up, but fairly universal, Mx. Kreski said. “Have a discussion that covers a broad range of substance use topics and informs teens of the potential risks of vaping, while avoiding stigma.”

The message for parents is “to talk to your kids about the risks of vaping,” said Mx. Kreski. “Prioritize open communication rather than punishment, and work together with your teens to prevent or reduce vaping.” The message for teens: “Understand that vaping has risks. You should feel empowered to talk to your parents or doctor about those risks. While it may seem like everyone’s vaping, the majority don’t. Keeping communication open between parents/caregivers, teens, and health care providers is one of the best ways to address these trends in vaping.”
 

Beware more powerful cannabis products

“While drug use in general is declining in adolescents, marijuana use remains very common,” Kelly A. Curran, MD, of the University of Oklahoma Health Sciences Center, Oklahoma City, said in an interview.

“There is growing evidence that marijuana is now the first drug used by adolescents – replacing alcohol and nicotine – and frequent use can lead to substance abuse,” said Dr. Curran, who specializes in adolescent medicine but was involved in the study. “Cannabis use patterns have evolved over time. As I frequently tell my patients and their families, new strains and hybrids of marijuana have higher potencies of THC. Many adolescents are eschewing smoking and in its place using marijuana concentrates (wax, oil, shatter) via vape, dab pen, or rig. Use of these methods puts adolescents at high risk of social and health complications such as [e-cigarette or vaping use-associated lung injury], cannabis hyperemesis syndrome, and psychosis – and understanding these patterns and associated drug use helps health care professionals and parents keep adolescents safe.”

The take-home message for clinicians is that marijuana use via vaping continues to rise and to become more common than “traditional” marijuana smoking, Dr. Curran said. “This increase is across genders, in nearly all race/ethnicities (especially in Latinx youth), and in youth from lower socioeconomic status.” Vaping marijuana is associated with other substance abuse, so health care professionals should include questions about different forms of marijuana use, such as vape, dab pen, or rig, when working with patients, and counsel patients and families about the risks associated with use of any of these products.

The study was supported by the National Center for Injury Prevention and Control and by the National Institute on Drug Abuse. The researchers had no financial conflicts to disclose. Dr. Curran had no financial conflicts to disclose and serves on the editorial advisory board of Pediatric News.

On the basis of history and presentation, this patient's psoriatic disease has probably evolved to psoriatic arthritis mutilans (PAM). PAM is considered the most severe form of psoriatic arthritis (PsA), causing joint destruction and functional disability. It is estimated to affect about 5% of patients with PsA, with an equal sex distribution. Psoriatic nail dystrophy, a hallmark of PsA, appears to be a clinical biomarker of PAM development. Patients with PAM are generally younger at diagnosis than those with less severe forms of disease. Disease-modifying antirheumatic drugs and anti-TNF therapy do not appear to prevent the development of PAM, as evidenced by the present case. 

In general, clinical presentation of PsA is heterogeneous and can be similar to that of other rheumatic diseases such as rheumatoid arthritis or osteoarthritis, complicating the differential diagnosis. The Classification Criteria for Psoriatic Arthritis (CASPAR) are considered the most sensitive diagnostic criteria, encompassing evidence of psoriasis; nail dystrophy; lab findings of typical autoantibodies (negative rheumatoid factor); and phenomena that are characteristic of PsA, like dactylitis.

Workup for PAM often includes radiography, ultrasound, and MRI or CT. With no established consensus, classification systems for the condition vary clinically and radiographically. Radiographic features suggestive of PAM include osteolysis or extended bone resorption; pencil-in-cup changes; joint subluxation; and, less often, ankylosis. Osteolysis has been defined as bone resorption with more than 50% loss of joint surface on both sides of the joint. Clinically, dissolution of the joint causes redundant, overlying skin with a telescoping motion of the digit. Other clinical features of PAM include digital shortening and flail joints. Of note, involvement of one small joint in the hands or feet is diagnostic of PAM.

In the setting of PsA, multiple genetic factors have been described, including presence of HLA-B27 and HLA-DRB1, but none are considered defining factors for the disease. A recent population-based study shows that presence of HLA-B27 was significantly increased among patients with PAM (45%) compared with patients with less severe PsA (13%) and healthy controls (13%). 

According to the American College of Rheumatology guidelines, first-line therapy in adult patients who have active PsA and are treatment-naive is a TNFi biologic agent. For the patient in this case, who has active PsA despite treatment with TNFi biologic monotherapy, switching to a different TNFi biologic may be appropriate; however, switching to an interleukin-17 inhibitor may also be considered because this patient has severe disease. Data on the comparative efficacy of different biological agents for treatment of PAM are not yet available.

The transition from perimenopause to menopause is accompanied by a proatherogenic shift in lipids and other circulating metabolites that potentially predispose women to cardiovascular disease (CVD). Now, for the first time, a new prospective cohort study quantifies the link between hormonal shifts and these lipid changes.

However, hormone therapy (HT) somewhat mitigates the shift and may help protect menopausal women from some elevated CVD risk, the same study suggests.

“Menopause is not avoidable, but perhaps the negative metabolite shift can be diminished by lifestyle choices such as eating healthily and being physically active,” senior author Eija Laakkonen, MD, University of Jyväskylä, Finland, told this news organization in an email.

“And women should especially pay attention to the quality of dietary fats and amount of exercise [they get] to maintain cardiorespiratory fitness,” she said, adding that women should discuss the option of HT with their health care providers.

Asked to comment, JoAnn Manson, MD, of Harvard Medical School, Boston, and past president of the North American Menopause Society, said there is strong evidence that women undergo negative cardiometabolic changes during the menopausal transition.

Changes include those in body composition (an increase in visceral fat and waist circumference), as well as unfavorable shifts in the lipid profile, as reflected by increases in low-density lipoprotein cholesterol (LDL-C) and triglycerides and a decrease in high-density lipoprotein cholesterol (HDL-C).

It’s also clear from a variety of cohort studies that HT blunts menopausal-related increases in body weight, percentage of body fat, as well as visceral fat, she said.

So the new findings do seem to “parallel” those of other perimenopausal to menopausal transition studies, which include HT having “favorable effects on lipids,” Dr. Manson said. HT “lowers LDL-C and increases HDL-C, and this is especially true when it is given orally,” but even transdermal delivery has shown some benefits, she observed.
 

Shift in hormones causes 10% of lipid changes after menopause

The new study, by Jari E. Karppinen, also of the University of Jyväskylä, and colleagues, was recently published in the European Journal of Preventive Cardiology. The data are from the Estrogenic Regulation of Muscle Apoptosis (ERMA) prospective cohort study.

In total, 218 women were tracked from perimenopause through to early postmenopause, 35 of whom started HT, mostly oral preparations. The women were followed for a median of 14 months. Their mean age was 51.7 years when their hormone and metabolite profiles were first measured.

Previous studies have shown that menopause is associated with levels of metabolites that promote CVD, but this study is the first to specifically link this shift with changes in female sex hormones, the researchers stress.

“Menopause was associated with a statistically significant change in 85 metabolite measures,” Mr. Karppinen and colleagues report.

Analyses showed that the menopausal hormonal shift directly explained the change in 64 of the 85 metabolites, with effect sizes ranging from 2.1% to 11.2%. 

These included increases in LDL-C, triglycerides, and fatty acids. Analyses were adjusted for age at baseline, duration of follow-up, education level, smoking status, alcohol use, physical activity, and diet quality.

More specifically, investigators found that all apoB-containing particle counts as well as particle diameters increased over follow-up, although no change occurred in HDL particles.

They also found cholesterol concentrations in all apoB-containing lipoprotein classes to increase and triglyceride concentrations to increase in very low-density lipoprotein and HDL particles.

“These findings, including HDL triglycerides, can be interpreted as signs of poor metabolic health since, despite higher HDL-C being good for health, high HDL triglyceride levels are associated with a higher risk of coronary heart disease,” Dr. Laakkonen emphasized.

Among the 35 women who initiated HT on study enrollment, investigators did note, on exploratory analysis, increases in HDL-C and reductions in LDL-C.

“The number of women starting HT was small, and the type of HT was not controlled,” Dr. Laakkonen cautioned, however.

“Nevertheless, our observations support clinical guidelines to initiate HT early into menopause, as this timing offers the greatest cardioprotective effect,” she added.

The study was supported by the Academy of Finland. The authors and Dr. Manson have reported no relevant financial relationships. Dr. Manson is a contributor to Medscape.

The transition from perimenopause to menopause is accompanied by a proatherogenic shift in lipids and other circulating metabolites that potentially predispose women to cardiovascular disease (CVD). Now, for the first time, a new prospective cohort study quantifies the link between hormonal shifts and these lipid changes.

However, hormone therapy (HT) somewhat mitigates the shift and may help protect menopausal women from some elevated CVD risk, the same study suggests.

“Menopause is not avoidable, but perhaps the negative metabolite shift can be diminished by lifestyle choices such as eating healthily and being physically active,” senior author Eija Laakkonen, MD, University of Jyväskylä, Finland, told this news organization in an email.

“And women should especially pay attention to the quality of dietary fats and amount of exercise [they get] to maintain cardiorespiratory fitness,” she said, adding that women should discuss the option of HT with their health care providers.

Asked to comment, JoAnn Manson, MD, of Harvard Medical School, Boston, and past president of the North American Menopause Society, said there is strong evidence that women undergo negative cardiometabolic changes during the menopausal transition.

Changes include those in body composition (an increase in visceral fat and waist circumference), as well as unfavorable shifts in the lipid profile, as reflected by increases in low-density lipoprotein cholesterol (LDL-C) and triglycerides and a decrease in high-density lipoprotein cholesterol (HDL-C).

It’s also clear from a variety of cohort studies that HT blunts menopausal-related increases in body weight, percentage of body fat, as well as visceral fat, she said.

So the new findings do seem to “parallel” those of other perimenopausal to menopausal transition studies, which include HT having “favorable effects on lipids,” Dr. Manson said. HT “lowers LDL-C and increases HDL-C, and this is especially true when it is given orally,” but even transdermal delivery has shown some benefits, she observed.

In states that adopted Medicaid expansion following the implementation of the Affordable Care Act (ACA), patients with cancer have improved 2-year overall survival rates, compared with patients in states that did not adopt the expansion.

The finding comes from an American Cancer Society study of more than 2 million patients with newly diagnosed cancer, published online in the Journal of the National Cancer Institute.

The analysis also showed that the evidence was strongest for malignancies with poor prognosis such as lung, pancreatic, and liver cancer, and also for colorectal cancer.

Importantly, improvements in survival were larger in non-Hispanic Black patients and individuals residing in rural areas, suggesting there was a narrowing of disparities in cancer survival by race and rurality.

“Our findings provide further evidence of the importance of expanding Medicaid eligibility in all states, particularly considering the economic crisis and health care disruptions caused by the COVID-19 pandemic,” said lead author Xuesong Han, PhD, scientific director of health services research at the American Cancer Society, in a statement. “What’s encouraging is the American Rescue Plan Act of 2021 provides new incentives for Medicaid expansion in states that have yet to increase eligibility.”

The ACA provided states with incentives to expand Medicaid eligibility to all low-income adults under 138% federal poverty level, regardless of parental status.

As of last month, just 12 states have not yet opted for Medicaid expansion, even though the American Rescue Plan Act of 2021 provides new incentives for those remaining jurisdictions. But to date, none of the remaining states have taken advantage of these new incentives.

An interactive map showing the status of Medicare expansion by state is available here. The 12 states that have not adopted Medicare expansion (as of April) are Alabama, Florida, Georgia, Kansas, Mississippi, North Carolina, South Carolina, South Dakota, Tennessee, Texas, Wisconsin, and Wyoming.  

The benefit of Medicaid expansion on cancer outcomes has already been observed in other studies. The first study to show a survival benefit was presented at the 2020 American Society of Clinical Oncology annual meeting. That analysis showed that cancer mortality declined by 29% in states that expanded Medicaid and by 25% in those that did not. The authors also noted that the greatest mortality benefit was observed in Hispanic patients.
 

Improved survival with expansion

In the current paper, Dr. Han and colleagues used population-based cancer registries from 42 states and compared data on patients aged 18-62 years who were diagnosed with cancer in a period of 2 years before (2010-2012) and after (2014-2016) ACA Medicaid expansion. They were followed through Sept. 30, 2013, and Dec. 31, 2017, respectively.

The analysis involved a total of 2.5 million patients, of whom 1.52 million lived in states that adopted Medicaid expansion and compared with 1 million patients were in states that did not.

Patients with grouped by sex, race and ethnicity, census tract-level poverty, and rurality. The authors note that non-Hispanic Black patients and those from high poverty areas and nonmetropolitan areas were disproportionately represented in nonexpansion states. 

During the 2-year follow-up period, a total of 453,487 deaths occurred (257,950 in expansion states and 195,537 in nonexpansion states).

Overall, patients in expansion states generally had better survival versus those in nonexpansion states, the authors comment. However, for most cancer types, overall survival improved after the ACA for both groups of states.

The 2-year overall survival increased from 80.6% before the ACA to 82.2% post ACA in expansion states and from 78.7% to 80% in nonexpansion states.

This extrapolated to net increase of 0.44 percentage points in expansion states after adjusting for sociodemographic factors. By cancer site, the net increase was greater for colorectal cancer, lung cancer, non-Hodgkin’s lymphoma, pancreatic cancer, and liver cancer.

For Hispanic patients, 2-year survival also increased but was similar in expansion and nonexpansion states, and little net change was associated with Medicaid expansion.

“Our study shows that the increase was largely driven by improvements in survival for cancer types with poor prognosis, suggesting improved access to timely and effective treatments,” said Dr. Han. “It adds to accumulating evidence of the multiple benefits of Medicaid expansion.”

Patients who have histologically active ulcerative colitis (UC) with a Mayo endoscopic subscore (MES) of 1 and a history of steroid use may be at increased risk for clinical relapse, according to a new single-center, retrospective analysis.

In recent years, treat-to-target approaches in UC have incorporated clinician and patient-reported outcomes, along with endoscopic remission, defined as MES 1 or less. However, additional studies showed a higher risk of relapse with MES 1, and the STRIDE-II (Selecting Therapeutic Targets in Inflammatory Bowel Disease) guidelines released in 2021 suggest that only MES 0 indicates endoscopic healing.

Nevertheless, there is concern that striving to achieve MES 0 could lead to overtreatment, since MES values are somewhat subjective, and patients with MES 1 sometimes report few or no symptoms. This led to the current study by Gyeol Seong, MD, and colleagues, published in Inflammatory Bowel Diseases.

Commenting on the study, Miguel Regueiro, MD, chair for the Digestive Disease and Surgery Institute and a professor of medicine at the Cleveland Clinic said “the question has always been, if the patient is in endoscopic remission and clinically feels well, how important is it to have histologically normal mucosa?”

In their retrospective study, Dr. Seong and colleagues analyzed data from 492 patients. The median age was 48, and 51.6% were male. The median duration of disease was 78 months. During a median follow-up of 549 days, 18.7% experienced a relapse, defined as “change or escalation of medication, hospitalization due to the aggravation of UC, or total colectomy.” Of these patients, 39.4% had used steroids and 51.4% had a MES score of 0 at the index endoscopy, and 70.5% had histologic improvement, as defined by a Geboes score of less than 3.1.

A Geboes score of 3.1 or higher and a history of steroid use was associated with an increased cumulative incidence of clinical relapse, compared with a Geboes score lower than 3.1 and no steroid use (P = .001). In a multivariate analysis, histologic activity alone was not a predictor of relapse. Among patients with an MES score of 1, a history of steroid use predicted risk of relapse (adjusted hazard ratio, 2.102; P = .006).

Although Dr. Regueiro said the new findings would not change his current practice, he does incorporate histopathology in clinical decision-making. In cases where a patient is in endoscopic remission but has histologic activity, he will consider adjusting the current medication rather than changing to a different therapeutic. “I wouldn’t recommend that we switch patients off one therapy to another just because of histologic activity.”

That’s because patients often improve dramatically after effective therapy. Dr. Regueiro said: “The one concern is whether the next medicine works as well as what the patient is already on? I’m also worried that we burn through our biologics too quickly. We go from one to another and another, sometimes I think we just need to optimize the one they’re on.”

The study does have the potential to influence surveillance for dysplasia, according to Dr. Regueiro, noting that a recent retrospective analysis showed an increased risk of dysplasia in UC with persistent histologic activity. “This suggests the need for a colonoscopy in a patient who has had ulcerative colitis for a number of years, even if there’s improvement but, on biopsy, there’s evidence of inflammation.”

According to Dr. Regueiro, such patients might benefit from a fecal calprotectin measurement in 3-6 months to monitor for colonic inflammation. Increased levels might be a sign that the patient is skipping medication doses, although other factors, like respiratory infections, can also explain the results. If the patient’s medication adherence is good, another therapy can be added or the dose increased, and the next endoscopy can be pushed up.

A key limitation to the study by Dr. Seong and colleagues is that it was based in South Korea. “Would this be the same in different countries and different populations? That is still a question,” said Dr. Regueiro.

Dr. Regueiro has received unrestricted educational grants from Abbvie, Janssen, UCB, Pfizer, Takeda, Celgene, Genentech, Gilead, Bristol-Myers Squibb, and Lilly. He has been on advisory boards or consulted for numerous companies. He also has relationships with the following CME companies: CME Outfitters, Imedex, GI Health Foundation, Cornerstones, Remedy, MJH Life Sciences, Medscape, MDEducation, WebMD, and HMPGlobal.

During a median follow-up of 549 days, 18.7% experienced a relapse, defined as “change or escalation of medication, hospitalization due to the aggravation of UC, or total colectomy.” Of these patients, 39.4% had used steroids and 51.4% had a MES score of 0 at the index endoscopy, and 70.5% had histologic improvement, as defined by a Geboes score of less than 3.1.

A Geboes score of 3.1 or higher and a history of steroid use was associated with an increased cumulative incidence of clinical relapse, compared with a Geboes score lower than 3.1 and no steroid use (P = .001). In a multivariate analysis, histologic activity alone was not a predictor of relapse. Among patients with an MES score of 1, a history of steroid use predicted risk of relapse (adjusted hazard ratio, 2.102; P = .006).

Although Dr. Regueiro said the new findings would not change his current practice, he does incorporate histopathology in clinical decision-making. In cases where a patient is in endoscopic remission but has histologic activity, he will consider adjusting the current medication rather than changing to a different therapeutic. “I wouldn’t recommend that we switch patients off one therapy to another just because of histologic activity.”

That’s because patients often improve dramatically after effective therapy. Dr. Regueiro said: “The one concern is whether the next medicine works as well as what the patient is already on? I’m also worried that we burn through our biologics too quickly. We go from one to another and another, sometimes I think we just need to optimize the one they’re on.”

The study does have the potential to influence surveillance for dysplasia, according to Dr. Regueiro, noting that a recent retrospective analysis showed an increased risk of dysplasia in UC with persistent histologic activity. “This suggests the need for a colonoscopy in a patient who has had ulcerative colitis for a number of years, even if there’s improvement but, on biopsy, there’s evidence of inflammation.”

According to Dr. Regueiro, such patients might benefit from a fecal calprotectin measurement in 3-6 months to monitor for colonic inflammation. Increased levels might be a sign that the patient is skipping medication doses, although other factors, like respiratory infections, can also explain the results. If the patient’s medication adherence is good, another therapy can be added or the dose increased, and the next endoscopy can be pushed up.

A key limitation to the study by Dr. Seong and colleagues is that it was based in South Korea. “Would this be the same in different countries and different populations? That is still a question,” said Dr. Regueiro.

Dr. Regueiro has received unrestricted educational grants from Abbvie, Janssen, UCB, Pfizer, Takeda, Celgene, Genentech, Gilead, Bristol-Myers Squibb, and Lilly. He has been on advisory boards or consulted for numerous companies. He also has relationships with the following CME companies: CME Outfitters, Imedex, GI Health Foundation, Cornerstones, Remedy, MJH Life Sciences, Medscape, MDEducation, WebMD, and HMPGlobal.

SAN FRANCISCO – Nearly half of all patients with severe, uncontrolled asthma who received a full course of the biologic agent tezepelumab (Tezspire) in the NAVIGATOR trial had a complete response to treatment at 1 year, results of a prespecified exploratory analysis indicated.

Among 471 patients assigned to tezepelumab who completed the on-treatment period of the phase 3 randomized trial, 46% had a complete response at 52 weeks, compared with 24% of patients assigned to placebo.

Complete response was defined as reduction in exacerbations of at least 50% over the previous year, improvement from baseline in Asthma Control Questionnaire 6 (ACQ-6) total score of at least 0.5 points, improvement in prebronchodilator forced expiratory volume in 1 second (pre-BD FEV₁), and physician-assessed Clinical Global Impression measure of clinical change (CGI-C) score.

“These data further support the efficacy of tezepelumab in a broad population of patients with severe, uncontrolled asthma,” said Njira Lugogo, MD, of the division of pulmonary and critical care medicine at the University of Michigan, Ann Arbor.

Dr. Lugogo presented results of the exploratory analysis at the American Thoracic Society’s international conference.
 

Exacerbations reduced, lung function improved

Primary results from NAVIGATOR, published in The New England Journal of Medicine, showed that patients with severe, uncontrolled asthma randomly assigned to tezepelumab had fewer exacerbations and better lung function, asthma control, and health-related quality of life compared with patients assigned to placebo.

The investigators noted that approximately 10% of patients with asthma have symptoms and exacerbations despite maximal standard-of-care controller therapy.

Tezepelumab is a human monoclonal antibody that inhibits action of thymic stromal lymphopoietin (TSLP), an epithelial cytokine that is released in response to airborne triggers of asthma. TSLP is a major contributor to initiation and persistence of airway inflammation, Dr. Lugogo said.

The on-treatment analysis looked at all patients in the trial who completed 52 weeks of treatment and had complete data for all criteria studied.

The odds ratios (OR) for patients on tezepelumab achieving each of the response criteria are shown in the table.

Exacerbations explored

In a separate presentation, Christopher S. Ambrose, MD, MBA, of AstraZeneca in Gaithersburg, Md., presented information from investigator-narrative descriptions of all hospitalization events related to asthma exacerbations (mild, moderate, or severe) that occurred while the investigator was blinded to each patient’s treatment assignment in NAVIGATOR.

In all, 39 of 531 patients (7.3%) assigned to placebo had a total of 78 exacerbations requiring hospitalization, compared with 13 of 528 patients (2.5%) assigned to tezepelumab. The latter group had a total of 14 exacerbations requiring hospitalization during the study.

Among hospitalized patients, 32 of the 39 assigned to placebo had severe, incapacitating exacerbations, compared with 5 of 13 assigned to tezepelumab.

Reported symptoms were generally similar between hospitalized patients in the two treatment groups, although there appeared to be trends toward lower incidence of dyspnea, fever, and tachycardia with tezepelumab.

Health care resource utilization, a surrogate marker for disease burden, was substantially lower for patients assigned to tezepelumab.

Infections were the most common triggers of exacerbations in both groups.

“These data provide further evidence that tezepelumab can reduce the burden of disease of severe uncontrolled asthma, both to patients and to health care systems,” Dr. Ambrose said.
 

Head-to-head studies needed

Although there have been no head-to-head comparisons of biologic agents for asthma to date, results of these studies suggest that tezepelumab has efficacy similar to that of other agents for reducing exacerbation, said Fernando Holguin, MD, MPH, from the University of Colorado at Denver, Aurora, who comoderated the oral session where the data were presented but was not involved in the study.

Biologic agents appear to be slightly more effective against type 2 inflammation in asthma, “but in general I think we give it to a broader severe population, so that’s exciting,” he told this news organization.

Comoderator Amisha Barochia, MBBS, MHS, of the National Institutes of Health, Bethesda, Md., told this news organization that head-to-head trials of biologic agents would provide important clinical information going forward.

“Should we switch to a different biologic or add a second biologic? Those are questions we need answers for,” she said.

The NAVIGATOR trial is funded by AstraZeneca and Amgen. Dr. Lugogo disclosed financial relationships with both companies. Dr. Holguin and Dr. Barochia have disclosed no financial relationships relevant to the studies presented.

Laparoscopic surgery can improve long-term overall survival (OS) compared with open surgery for patients with rectal cancer, according to findings from a large meta-analysis.

The estimated 5-year OS rate for patients who underwent laparoscopic surgery was 76.2%, vs. 72.7% for those who had open surgery.

“The survival benefit of laparoscopic surgery is encouraging and supports the routine use of laparoscopic surgery for adult patients with rectal cancer in the era of minimally invasive surgery,” wrote the authors, led by Leping Li, MD, of the department of gastrointestinal surgery, Shandong (China) Provincial Hospital.

The article was published online in JAMA Network Open.

Surgery is an essential component in treating rectal cancer, but the benefits of laparoscopic vs. open surgery are not clear. Over the past 15 years, randomized clinical trials (RCTs) have shown comparable long-term outcomes for laparoscopic and open surgery. However, in most meta-analyses that assessed the evidence more broadly, researchers used an “inappropriate” method for the pooled analysis. Dr. Li and colleagues wanted to perform their own meta-analysis to more definitively understand whether the evidence on long-term outcomes supports or opposes the use of laparoscopic surgery for rectal cancer.

In the current study, the authors conducted an individual participant data meta-analysis using time-to-event data and focused on the long-term survival outcomes after laparoscopic or open surgery for adult patients with rectal cancer.

Ten articles involving 12 RCTs and 3,709 participants were included. In these, 2,097 patients were randomly assigned to undergo laparoscopic surgery, and 1,612 were randomly assigned to undergo open surgery. The studies covered a global population, with participants from Europe, North America, and East Asia.

In a one-stage analysis, the authors found that disease-free survival was slightly better among patients who underwent laparoscopic surgery, but the results were statistically similar (hazard ratio [HR], 0.92; P = .26).

However, when it came to OS, those who had undergone laparoscopic surgery fared significantly better (HR, 0.85; P = .02).

These results held up in the two-stage analysis for both disease-free survival (HR, 0.92; P = .25) and OS (HR, 0.85; P = .02). A sensitivity analyses conducted with large RCTs yielded similar pooled effect sizes for disease-free survival (HR, 0.91; P = .20) and OS (HR, 0.84; P = .03).

The authors highlighted several reasons why laparoscopic surgery may be associated with better survival. First, the faster recovery from the minimally invasive procedure could allow patients to begin adjuvant therapy earlier. In addition, the reduced stress responses and higher levels of immune function among patients undergoing minimally invasive surgery may contribute to a long-term survival advantage.

“These findings address concerns regarding the effectiveness of laparoscopic surgery,” the authors wrote. However, “further studies are necessary to explore the specific mechanisms underlying the positive effect of laparoscopic surgery on OS.”

Infertile men may be twice as likely to develop invasive breast cancer as those without fertility issues, according to new research funded by the charity Breast Cancer Now and published in Breast Cancer Research. The study is one of the largest ever into male breast cancer, enabling the team to show a highly statistically significant association.  

A link with infertility had been suspected, since parity markedly reduces the risk of female breast cancer; there are known genetic links in both sexes, and a high risk of both breast cancer and infertility among men with Klinefelter syndrome, suggesting some sex hormone-related involvement. However, the rarity of breast cancer in men – with an annual incidence of about 370 cases and 80 deaths per year in the United Kingdom – meant that past studies were necessarily small and yielded mixed results.

“Compared with previous studies, our study of male breast cancer is large,” said study coauthor Michael Jones, PhD, of the division of genetics and epidemiology at the Institute of Cancer Research (ICR) in London. “It was carried out nationwide across England and Wales and was set in motion more than 15 years ago. Because of how rare male breast cancer is, it took us over 12 years to identify and interview the nearly 2,000 men with breast cancer who were part of this study.”

The latest research is part of the wider Breast Cancer Now Male Breast Cancer Study, launched by the charity in 2007. For the new study, the ICR team interviewed 1,998 males living in England and Wales who had been diagnosed with breast cancer between 2005 and 2017. All were aged under 80 but most 60 or older at diagnosis; 92% of their tumors were invasive, and almost all were estrogen receptor positive (98.5% of those with known status).

Their responses were compared with those of a control group of 1,597 men without breast cancer, matched by age at diagnosis and geographic region, recruited from male non-blood relatives of cases and from husbands of women participating in the Generations cohort study of breast cancer etiology.
 

Raised risk with history of male infertility

Overall, 112 cases (5.6%) and 80 controls (5.0%) reported that they had had infertility problems for which they or their partner had consulted a doctor or infertility clinic. This represented a raised odds ratio of 1.29 (95% confidence interval, 0.94-1.77), which was statistically not significant. However, when analyzed by outcome of the infertility consultation, there was a significant and more than doubled risk of breast cancer among men who were diagnosed as the source of the couple’s infertility (OR = 2.03 [1.18-3.49]), whereas this was not the case among men whose partner was the source (OR = 0.86 [0.51-1.45]) or for whom no source was identified (OR = 1.26 [0.71-2.24]).

In addition, proportionately fewer cases (1,615, or 80.8%) compared with controls (1,423, or 89.1%) had fathered any children, also giving a statistically significantly raised risk of breast cancer for men with no biological children (OR = 1.50 [1.21-1.86], P < .001), “congruent with infertility as a risk factor,” the authors said. The risk was statistically significant for invasive tumors but not for the much smaller number of in situ tumors.

Analysis by number of children showed a decreasing risk with increasing numbers of children, with a highly significant (P < .001) inverse trend where zero was included as a value, but a borderline significant trend (P = .04) if it was not. The team noted that number of children beyond one is difficult to interpret as an indicator of male fertility, since it may more reflect social and cultural factors than fertility per se.

Baseline demographic factors were adjusted for in the risk analyses, and results were not materially changed by sensitivity analyses adjusting additionally for alcohol consumption, smoking, liver disease, and family history of breast cancer. The association also largely remained after exclusion of patients with other preexisting potential confounders including severe obesity and testicular abnormalities, and was consistent irrespective of HER-2 status (there were too few ER-negative tumors to analyze results by ER status).
 

Potential underlying factors

“The causes of breast cancer in men are largely unknown, partly because it is rare and partly because previous studies have been small,” Dr. Jones said. “The evidence presented in our study suggests that the association of infertility and breast cancer should be confirmed with further research, and future investigations are needed into the potential underlying factors, such as hormone imbalances.”

Commenting on the study, Fiona Osgun, senior health information manager at Cancer Research UK, told this news organization: “Overall, there isn’t strong evidence that infertility is a risk factor for male breast cancer. This study helps to shed light onto a cancer type that is sadly still not very well understood, but much more research is needed to say that infertility is a risk factor for male breast cancer.”

She added that although male breast cancer is a rare condition, it’s still important for men to be aware of what looks and feels normal for them, and to be encouraged to seek medical advice if something is not quite right.

A spokesperson for Breast Cancer UK told this news organization: “[We] believe it’s important to understand what leads to breast cancer in men as well as women and that high quality, long-term studies such as this will help with this understanding.

The findings are consistent with an earlier study that found that U.S. men who have never fathered children are at higher risk of breast cancer. This new long-term U.K. study provides strong evidence, which supports this finding.  

“As the authors note, the biological reasons are unclear, but may be associated with altered hormone levels. The ratio of circulating levels of estrogen and androgens (e.g. testosterone) is crucial in healthy functioning of breast tissue. Disruption to this, for example as a result of damage to testes, may affect both fertility and breast cancer risk.

“It is also possible that external factors, such as exposure to certain endocrine (hormone) disrupting chemicals (EDCs), which affect sex hormones, may also affect both fertility and breast cancer risk.

“More studies into breast cancer in men are needed to help us understand better all the risk factors associated with this disease including both hormonal factors and chemical exposures.”

Simon Vincent, PhD, director of research, support, and influencing at Breast Cancer Now, said: “Research has discovered different treatments directed at some features of breast cancer in women; however, breast cancer is not as well understood for men. This is why Breast Cancer Now funds the Male Breast Cancer Study, which looks at what might cause the disease in men. Discovering a link between infertility and male breast cancer is a step towards us understanding male breast cancer and how we could find more ways to diagnose and treat men – and possibly women – with this devastating disease.”

The latest research is part of the wider Breast Cancer Now Male Breast Cancer Study, launched by the charity in 2007. For the new study, the ICR team interviewed 1,998 males living in England and Wales who had been diagnosed with breast cancer between 2005 and 2017. All were aged under 80 but most 60 or older at diagnosis; 92% of their tumors were invasive, and almost all were estrogen receptor positive (98.5% of those with known status).

Their responses were compared with those of a control group of 1,597 men without breast cancer, matched by age at diagnosis and geographic region, recruited from male non-blood relatives of cases and from husbands of women participating in the Generations cohort study of breast cancer etiology.
 

Raised risk with history of male infertility

Overall, 112 cases (5.6%) and 80 controls (5.0%) reported that they had had infertility problems for which they or their partner had consulted a doctor or infertility clinic. This represented a raised odds ratio of 1.29 (95% confidence interval, 0.94-1.77), which was statistically not significant. However, when analyzed by outcome of the infertility consultation, there was a significant and more than doubled risk of breast cancer among men who were diagnosed as the source of the couple’s infertility (OR = 2.03 [1.18-3.49]), whereas this was not the case among men whose partner was the source (OR = 0.86 [0.51-1.45]) or for whom no source was identified (OR = 1.26 [0.71-2.24]).

In addition, proportionately fewer cases (1,615, or 80.8%) compared with controls (1,423, or 89.1%) had fathered any children, also giving a statistically significantly raised risk of breast cancer for men with no biological children (OR = 1.50 [1.21-1.86], P < .001), “congruent with infertility as a risk factor,” the authors said. The risk was statistically significant for invasive tumors but not for the much smaller number of in situ tumors.

Analysis by number of children showed a decreasing risk with increasing numbers of children, with a highly significant (P < .001) inverse trend where zero was included as a value, but a borderline significant trend (P = .04) if it was not. The team noted that number of children beyond one is difficult to interpret as an indicator of male fertility, since it may more reflect social and cultural factors than fertility per se.

Baseline demographic factors were adjusted for in the risk analyses, and results were not materially changed by sensitivity analyses adjusting additionally for alcohol consumption, smoking, liver disease, and family history of breast cancer. The association also largely remained after exclusion of patients with other preexisting potential confounders including severe obesity and testicular abnormalities, and was consistent irrespective of HER-2 status (there were too few ER-negative tumors to analyze results by ER status).
 

Potential underlying factors

“The causes of breast cancer in men are largely unknown, partly because it is rare and partly because previous studies have been small,” Dr. Jones said. “The evidence presented in our study suggests that the association of infertility and breast cancer should be confirmed with further research, and future investigations are needed into the potential underlying factors, such as hormone imbalances.”

Commenting on the study, Fiona Osgun, senior health information manager at Cancer Research UK, told this news organization: “Overall, there isn’t strong evidence that infertility is a risk factor for male breast cancer. This study helps to shed light onto a cancer type that is sadly still not very well understood, but much more research is needed to say that infertility is a risk factor for male breast cancer.”

She added that although male breast cancer is a rare condition, it’s still important for men to be aware of what looks and feels normal for them, and to be encouraged to seek medical advice if something is not quite right.

A spokesperson for Breast Cancer UK told this news organization: “[We] believe it’s important to understand what leads to breast cancer in men as well as women and that high quality, long-term studies such as this will help with this understanding.

The findings are consistent with an earlier study that found that U.S. men who have never fathered children are at higher risk of breast cancer. This new long-term U.K. study provides strong evidence, which supports this finding.  

“As the authors note, the biological reasons are unclear, but may be associated with altered hormone levels. The ratio of circulating levels of estrogen and androgens (e.g. testosterone) is crucial in healthy functioning of breast tissue. Disruption to this, for example as a result of damage to testes, may affect both fertility and breast cancer risk.

“It is also possible that external factors, such as exposure to certain endocrine (hormone) disrupting chemicals (EDCs), which affect sex hormones, may also affect both fertility and breast cancer risk.

“More studies into breast cancer in men are needed to help us understand better all the risk factors associated with this disease including both hormonal factors and chemical exposures.”

Simon Vincent, PhD, director of research, support, and influencing at Breast Cancer Now, said: “Research has discovered different treatments directed at some features of breast cancer in women; however, breast cancer is not as well understood for men. This is why Breast Cancer Now funds the Male Breast Cancer Study, which looks at what might cause the disease in men. Discovering a link between infertility and male breast cancer is a step towards us understanding male breast cancer and how we could find more ways to diagnose and treat men – and possibly women – with this devastating disease.”

Infertile men may be twice as likely to develop invasive breast cancer as those without fertility issues, according to new research funded by the charity Breast Cancer Now and published in Breast Cancer Research. The study is one of the largest ever into male breast cancer, enabling the team to show a highly statistically significant association.  

A link with infertility had been suspected, since parity markedly reduces the risk of female breast cancer; there are known genetic links in both sexes, and a high risk of both breast cancer and infertility among men with Klinefelter syndrome, suggesting some sex hormone-related involvement. However, the rarity of breast cancer in men – with an annual incidence of about 370 cases and 80 deaths per year in the United Kingdom – meant that past studies were necessarily small and yielded mixed results.
