BERLIN – In separate trials conducted in patients with hidradenitis suppurativa (HS), two biologics that inhibit the activity of interleukin-17A (IL-17A) and IL-17F were associated with highly encouraging rates of control.

One of the trials evaluated a nanobody inhibitor, sonelokimab, a molecule with a substantially smaller size than traditional monoclonal antibodies (40 kilodaltons vs. 150 kilodaltons). After 24 weeks of treatment, the most effective of the two study doses almost doubled the proportion of patients with complete resolution of draining tunnels (41.1% vs. 23.8%; P < .05) relative to placebo.

“I think the size of sonelokimab is important,” Brian Kirby, MD, a consultant dermatologist at St. Vincent’s Hospital, Dublin, said at the annual congress of the European Academy of Dermatology and Venereology. “We think the smaller size results in better penetration of inflamed tissue,” he added, noting that penetration of abscesses, fistulae, and tunnels has been recognized in the past as a potential weakness of the larger monoclonal antibodies.

The other set of anti-17-A/F set of data were generated by a pooled 48-week maintenance from the BE HEARD I and II trials with bimekizumab. The 16-week data from these two trials were presented at the annual meeting of the American Academy of Dermatology earlier this year.
 

IL-17A/F trials

Both the 16-week phase 2 data with sonelokimab and the 48-week pooled phase 3 maintenance data with bimekizumab were presented as late-breakers at the EADV Congress.

In the sonelokimab trial, called MIRA, 234 adults with HS were randomized in a 2:2:2:1 ratio to one of the two experimental arms, placebo, or a reference arm with the tumor necrosis factor (TNF) inhibitor adalimumab. Nearly 64% had Hurley stage II HS.

The primary endpoint was a 75% or greater reduction in total abscesses and nodules with no increase in draining tunnel count (HiSCR75) from baseline. Dr. Kirby said that this is more rigorous than the HiSCR50 endpoint more commonly used in HS clinical trials. Treatments were administered every 2 weeks for the first 8 weeks of a planned follow-up of 24 weeks and then every 4 weeks thereafter.

At 16 weeks, according to the data Dr. Kirby presented, both doses of sonelokimab were more active than placebo, but Dr. Kirby reported that the lower dose performed better for most objective endpoints.

For example, the HiSCR75 was reached by 43.3% of those randomized to the 120-mg dose (P < .001 vs. placebo), 34.8% of those randomized to the 240-mg dose (P <.01), and 14.7% of those randomized to placebo.

For HiSCR50, response rates were 65.7%, 53.0%, and 27.9%, for the 120-mg, 240-mg, and placebo arms, respectively. Again, both the lower dose (P < .001) and the higher dose (P < .01) were significantly superior to placebo.

On the International Hidradenitis Suppurativa Severity Score System (IHS4), which counts nodules and abscesses, score reductions were 19.3, 14.5, and 7.9 for the lower dose, higher dose, and placebo, respectively, with a greater statistical advantage for the lower relative to the higher dose over placebo (P <.001 vs. P <.01).

However, patient-focused outcomes were not necessarily greater for the lower dose. For the patient-completed measure, the Numerical Rating Scale 50% reduction in skin pain (NRS50), the proportion of patients responding at 12 weeks was numerically greater for the 240-mg dose (41.3%) than with the 120-mg dose (32.0%), although both reached the same statistical advantage (P < .001) over the 4.3% who reached this level of response on placebo.

For the Dermatology Life Quality Index (DLQI) and the Patient Global Impression of Severity (PGI-S), improvements from baseline were similar for the lower and higher dose, although there was a modest numerical and statistical advantage for the higher dose over placebo (P < .001 vs. P <.01).

The HiSCR50 (57.6%) and HiSCR75 (36.4%) responses were both lower for those randomized to the TNF inhibitor adalimumab relative to sonelokimab, but the smaller number of patients in this arm prohibited a statistical comparison.

Although oral candidiasis was more common among patients receiving either dose of sonelokimab than placebo, these were of mild to moderate severity. Dr. Kirby said that there were no unexpected safety issues, and sonelokimab was generally well tolerated.

The results are encouraging, but Dr. Kirby acknowledged that data are now needed to confirm that resolution of tunnels and fistulae is greater with a nanobody inhibitor of IL-17A/F than other targeted therapies. Even if this is validated, he said studies are needed to prove that the small relative molecule size is the reason behind the benefits.
 

Forty-eight–week bimekizumab data

From the pooled BE HEARD I and BE HEARD II maintenance data, the major message is that the robust responses observed at 16 weeks versus placebo were maintained at 48 weeks. More than 75% of patients retained a HiSCR50 response and more than 55% achieved a HiSCR75 response at the 48-week follow-up. The durable response was also reflected in other measures, according to Christos C. Zouboulis, MD, PhD, director of the department of dermatology, Brandenburg Medical School, Neuruppin, Germany.

“Improvements in disease severity were seen over time,” Dr. Zouboulis reported. “The majority of patients with severe HS at baseline shifted to mild to moderate disease according to the IHS4 classification.”

To the degree that both sonelokimab and bimekizumab target IL-17A/F, these data are mutually reinforcing. Dr. Kirby said that there is a sizable body of data implicating IL-17A/F in driving HS, and the activity of inhibitors in support the clinical value of IL-17A/F suppression.

On Oct. 18, shortly after the EADV meeting concluded, the Food and Drug Administration approved bimekizumab for treating moderate to severe plaque psoriasis, the first approved indication in the United States. In the European Union, it was approved for psoriasis in 2021, and for psoriatic arthritis and ankylosing spondylitis in June 2023.

Dr. Kirby has financial relationships with more than 10 pharmaceutical companies, including MoonLake, which is developing sonelokimab and sponsored the MIRA trial. Dr. Christos, president of the European HS Foundation, has financial relationships with multiple pharmaceutical companies, including UCB, which makes bimekizumab and provided funding for the BE HEARD I and II trials.

Reducing exposure to tobacco smoke may reduce the burden of chronic obstructive pulmonary disease, and public health measures are needed, according to a new Tobacco Knowledge Summary from the World Health Organization.

“Smoking is a major risk factor for COPD and leads to airway inflammation and remodeling associated with lung destruction,” and contributes to approximately 70% of COPD cases worldwide, according to the statement.

Types of tobacco exposure include not only traditional smoked tobacco products (cigarettes, cigars, pipes, water pipes, kreteks, and bidis), but also smokeless tobacco, heated tobacco products, and electronic nicotine delivery systems; the addition of chemicals and flavors can increase the appeal of tobacco products and promote addiction, the authors wrote. Hookahs and water pipes “are at least as detrimental to lung health as smoking cigarettes and should not be considered as a safe alternative,” they added.

The risk of COPD extends to new e-cigarette products, the authors noted. A study in the American Journal of Preventive Medicine showed that current users of e-cigarettes had a 75% increased risk of developing COPD compared with individuals who have never used e-cigarettes.

Individuals with COPD also face an increased risk of cardiovascular disease and type 2 diabetes, and smokers with COPD who quit not only improve their COPD but also reduce their risk of developing these conditions, the authors said.
 

Mechanism of action explored

The authors noted how tobacco smoking may cause COPD when inhaled particles are deposited through the airway.

Growing evidence suggests that extracellular vesicles may play a role in the development of lung disorders such as COPD, and cigarette smoke can have an impact through this channel. A study published in the American Journal of Respiratory and Critical Care Medicine offered evidence of a potential link between exposure to cigarette smoke and the generation of a unique extracellular vesicle population that could promote the development of lung damage. In the study, Matthew C. Madison, MD, of the University of Alabama, Birmingham, and colleagues examined activity in extracellular vesicles from the bronchoalveolar lavage (BAL) fluid of smoke-exposed mice and human smokers who were otherwise healthy.

The researchers found that airway extracellular vesicles in mice or humans exposed to cigarette smoke had the ability to cause rapid lung damage when transferred into naive recipient mice. The results provide a new model that can inform preclinical COPD research, they wrote.
 

Public health action needed

“In recognition of COPD and Lung Cancer Awareness Month, the World Health Organization (WHO) emphasizes the impact of various forms of tobacco use on COPD,” Dharani K. Narendra, MD, of Baylor College of Medicine, Houston, said in an interview.

“This article focuses on the different types of tobacco exposure, the health care burden associated with COPD, and the risk of developing lung cancer. It also addresses the high-risk groups, especially youth, underscoring the importance of public education and the implementation of restrictions on tobacco use to combat these growing concerns,” she said.

“Education, awareness, and targeted interventions are essential for smoking cessation and COPD management,” said Dr. Narendra. “These elements are key to informing the public about smoking risks, encouraging behavioral change, and ultimately reducing the incidence of smoking-related diseases,” she emphasized.

The WHO statement called for population-level interventions including brief advice to tobacco users, toll-free quit lines, pharmacological interventions, use of messaging and chatbots to provide quit support, and the WHO quit tobacco mobile app.

“It is imperative that all tobacco users, particularly those living in low- to middle-income countries, have access to comprehensive cessation support aligned with WHO recommendations,” the authors wrote.

Finally, the authors emphasized the need to protect children and teens from the dangers of tobacco use through product regulation and to expose the tobacco industry’s marketing tactics.

“The article offers a comprehensive look at different types of tobacco exposure and their contribution to the development of COPD,” Dr. Narendra told this news organization. “Notably, it presents groundbreaking evidence of a strong association between the use of electronic nicotine delivery systems (ENDS) and heated tobacco products to development of COPD; additionally, it provides valuable guidance on smoking cessation resources for physicians to help patients quit smoking,” she said.

Looking ahead, more research is needed on “developing and sustaining state-specific or population-specific interventions for effective smoking cessation programs, and reducing the burden of COPD,” Dr. Narendra said.

The study by Madison and colleagues was supported by the National Heart, Lung, and Blood Institute, the National Institute of General Medical Science, the U.S. Veterans Affairs Administration, the Cystic Fibrosis Foundation Research Development Program, and the Veterans Affairs Merit grant.

Additional financial support came from Imperial College London, a Wellcome Trust Senior Research Fellowship, and Rosetrees Trust/The Stoneygate Trust.

Dr. Narendra had no financial conflicts to disclose but serves as a member of the editorial board of CHEST Physician.

SAN DIEGO – In the spring of 2024, the American College of Rheumatology is expected to release guidelines to help inform the screening, monitoring, and treatment of interstitial lung disease (ILD) in people with systemic autoimmune rheumatic diseases (SARDs).

The guidelines, which were previewed during a session at the ACR’s annual meeting, will include 50 recommendations, 3 of which met criteria for a strong rating:

• For people with SARDs at increased risk of developing ILD, the authors strongly recommend against screening with surgical lung biopsy.
• For people with systemic sclerosis (SSc)-related ILD, the authors strongly recommend against glucocorticoids as a first-line ILD treatment.
• For people with SSc-related ILD progression despite an initial ILD treatment, the authors strongly recommend against using long-term glucocorticoids.

Elana J. Bernstein, MD, MSc, a rheumatologist who directs the Columbia/New York-Presbyterian Scleroderma Center, and Sindhu R. Johnson, MD, a rheumatologist who directs the Toronto Scleroderma Program at the University of Toronto, provided a sneak peek of the recommendations to attendees before anticipated publication in Arthritis & Rheumatology and Arthritis Care & Research. For now, guideline summaries for screening and monitoring and treatment are currently available, and three manuscripts are under peer review: one about screening and monitoring, one about treatment, and one about the patient panel that participated in the effort.

Pediatric patients with SARDs excluded

The guidelines’ population of interest was people 17 years of age and older who were diagnosed with SARDs with a high risk of ILD. Pediatric patients with SARDs were excluded from the endeavor, as were those with systemic lupus erythematosus, antineutrophil cytoplasmic antibody–associated vasculitis, sarcoidosis, ankylosing spondylitis, undifferentiated connective tissue disease, interstitial pneumonia with autoimmune features, and those with unclassifiable ILD.

In the realm of screening, the guideline authors conditionally recommend two screening tests for patients considered at increased risk of ILD: pulmonary function tests and high-resolution chest CT (HRCT). Pulmonary function tests should include spirometry, lung volumes, and diffusion capacity. “Office spirometry alone is insufficient,” said Dr. Johnson, who served as lead author of the guidelines. And while a HRCT scan is recommended, “some patients may present to the emergency room with acute onset shortness of breath, and they may receive a CT angiogram to screen for pulmonary embolism,” she said. “It’s important to note that CT angiograms are performed in incomplete inspiration to maximize pulmonary artery enhancement. This may produce atelectasis that may obscure or mimic ILD. As a result, CTA studies are often inadequate to screen for ILD.”

Once a patient is diagnosed with ILD, three tests are recommended for monitoring: pulmonary function testing (every 3-6 months the first year in patients with IIM and SSc, then less frequently once stable, and every 3-12 months in the first year in patients with RA, SjD, and MCTD, then less frequently once stable); ambulatory desaturation testing every 3-12 months; and HRCT as needed. Dr. Johnson noted that while that the screening of ILD lies within the realm of rheumatologists, “once a patient is diagnosed, we are encouraged to comanage these patients with pulmonologists,” she said. “Ambulatory desaturation testing is not an infrequent test in the hands of pulmonologists. This is where co-management can be helpful.” She characterized a 6-minute walk test with continuous oximetry as “insufficient and is not synonymous with ambulatory desaturation testing. Ambulatory desaturation testing includes up titration of oxygen if a patient desaturates.”

The guidelines conditionally recommend against using chest radiography, 6-minute walk test distance, ambulatory desaturation testing, and bronchoscopy for ILD screening, and there is a strong recommendation against surgical lung biopsy. “However, there are unique circumstances where these tests may be considered,” Dr. Johnson said. “For example, ambulatory desaturation testing may be helpful if a patient is unable to perform a pulmonary function test. Bronchoscopy may be used to rule out infection, sarcoidosis, lymphoma, or alveolar hemorrhage, and surgical lung biopsy may be considered if you’re trying to rule out a malignancy.”

Similarly, several tests are conditionally recommended against for the monitoring of ILD, including chest radiography, the 6-minute walk test distance, and bronchoscopy. “But there are unique circumstances where they may be considered,” she said. “The 6-minute walk test may be used if a patient is unable to perform a pulmonary function test or if they’re being assessed for lung transplantation. Bronchoscopy may be used to rule out infection or alveolar hemorrhage.”
 

Preferred treatment options described

First-line treatment recommendations for ILD were based on the best available published evidence, voting panel expertise, and patient preferences. For SSc, the preferred treatment options include mycophenolate (CellCept), tocilizumab (Actemra), or rituximab (Rituxan and biosimilars), while additional options include cyclophosphamide, nintedanib (Ofev), and azathioprine. For myositis, the preferred treatment options include mycophenolate, azathioprine, rituximab, or calcineurin inhibitors, while additional options include a Janus kinase (JAK) inhibitor or cyclophosphamide. For MCTD, the preferred treatment options include mycophenolate, azathioprine, or rituximab, while additional options include tocilizumab or cyclophosphamide. For RA and Sjögren’s, the preferred treatment options include mycophenolate, azathioprine, or rituximab, while additional options include cyclophosphamide. Dr. Johnson emphasized that there was low certainty evidence to recommend one treatment over another. “Many situations might lead a provider to choose a different option for ILD treatment, such as the presence of comorbidities or extra-pulmonary disease,” she said. “So, while our guidelines were focused on effectiveness for ILD, providers may choose therapies that will help ILD and other disease manifestations.”

The guidelines conditionally recommend a short course of glucocorticoids as a bridging therapy or for treatment of a flare of ILD in patients with myositis, MCTD, RA, and Sjögren’s. The panel strongly recommends against the use of glucocorticoids in patients with SSc due to the concern for inducing a scleroderma renal crisis. “While this may be common knowledge for rheumatologists, it may not be common knowledge for pulmonologists,” she said. “So here is an opportunity to educate our pulmonology colleagues in our consultation notes.”

The guidelines also include recommendations for progression of ILD, which was defined using the INBUILD trial criteria. Mycophenolate is conditionally recommended to be the first ILD treatment for all SARDs when progression occurs, if it wasn’t the first ILD treatment used. “If it was, then other medications that rheumatologists are used to can be considered as the next ILD treatment in the face of progression: rituximab, nintedanib, tocilizumab, and cyclophosphamide,” she said. The guidelines include a conditional recommendation against long-term glucocorticoid use in myositis, MCTD, RA, and Sjögren’s, plus a strong recommendation against long-term glucocorticoid use in SSc. Finally, there is a conditional recommendation of referral for lung transplant evaluation at the appropriate time at experienced centers.

A patient panel provided input

For the undertaking, a core team that included six rheumatologists; one pulmonologist; one thoracic radiologist; one expert on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology; and two literature review experts developed clinically relevant population, intervention, comparator, and outcomes (PICO) questions. The literature review team included 13 rheumatologists, 8 pulmonologists, and 3 methodologists. Finally, a 21-member patient panel was convened to share their values and preferences regarding screening, monitoring, and treatment of SARD-related ILD. Of these, Dr. Bernstein said that 4 were at risk for ILD and 17 had been diagnosed with ILD. Next, the literature review team conducted a systematic review and used the GRADE methodology to rate the available evidence as high, moderate, low, or very low. Then, a voting panel comprising 13 rheumatologists, 10 pulmonologists, 1 radiologist, and 3 patients from the patient panel cast votes for each PICO question and made final recommendations.

The review of evidence left the guidelines authors with 241 PICO questions, “which is a lot,” Dr. Bernstein said. “To put this in perspective, some guidelines address only 10 or 15 PICO questions. Fortunately, we had a dedicated group of experts who were up to the challenge.” Dr. Johnson emphasized that the forthcoming guidelines should not be used by insurers to mandate a specific order of prescribing. “Clinicians must retain the latitude to prescribe medications based on individual patient factors and preferences,” she said.

Dr. Bernstein disclosed that she is an adviser to, a consultant for, and has received grant or research support from Boehringer Ingelheim and has also received grant or research support from Kadmon and Pfizer. Dr. Johnson disclosed that she has received research support from the American College of Rheumatology to develop these guidelines. She has also been an investigator for trials sponsored by Bristol-Myers Squibb, Roche, and Boehringer Ingelheim and has mitigated these relevant conflicts of interest 1 year prior to the development of these guidelines, and will continue to do so for the foreseeable future.

SAN DIEGO – In the spring of 2024, the American College of Rheumatology is expected to release guidelines to help inform the screening, monitoring, and treatment of interstitial lung disease (ILD) in people with systemic autoimmune rheumatic diseases (SARDs).

The guidelines, which were previewed during a session at the ACR’s annual meeting, will include 50 recommendations, 3 of which met criteria for a strong rating:

• For people with SARDs at increased risk of developing ILD, the authors strongly recommend against screening with surgical lung biopsy.
• For people with systemic sclerosis (SSc)-related ILD, the authors strongly recommend against glucocorticoids as a first-line ILD treatment.
• For people with SSc-related ILD progression despite an initial ILD treatment, the authors strongly recommend against using long-term glucocorticoids.

The US Preventive Services Task Force (USPSTF)¹ is comprised of an independent panel of preventive services clinician experts who make evidence-based recommendations, with the letter grade assigned based on the strength of the evidence, from A through D (TABLE 1), on preventive services such as health screenings, shared decision making patient counseling, and preventive medications.  Both A and B recommendations are generally accepted by both government and most private health insurance companies as a covered preventive benefit with no or minimal co-pays.

In 2002, the USPSTF released a Grade B recommendation that screening mammography for average-risk patients (with patients referring to persons assigned female at birth who have not undergone bilateral mastectomy) should take place starting at age 40 and be repeated every 1 to 2 years.² This was consistent with or endorsed by most other national breast cancer screening guidelines,  including the American College of Obstetricians and Gynecologists (ACOG), National Comprehensive Cancer Network (NCCN), the American Cancer Society (ACS), and the American College of Radiology. 

In 2009, the USPSTF changed this Grade B recommendation, instead recommending biennial screening mammography for women aged 50 to 74.³ The most significant change in the revised guideline was for patients aged 40 to 49, where the recommendation was “against routine screening mammography.” They went on to say that the decision to start “biennial screening mammography before the age of 50 years should be an individual one and take patient context into account, including the patient’s values regarding specific benefits and harms.” Other prominent national guideline groups (ACOG, NCCN, ACS) did not agree with this recommendation and maintained that patients aged 40 to 49 should continue to be offered routine screening mammography either annually (NCCN, ACS) or at 1-to-2-year intervals (ACOG).^4-6 The American College of Physicians and the American Academy of Family Practice endorsed the 2016 USPSTF guidelines, creating a disparity in breast cancer mammography counseling for averagerisk patients in their 40s.⁷

In 2016, the USPSTF revisited their breast cancer screening recommendation and renewed their 2009 recommendation against routine screening in patients aged 40 to 49, with the American College of Physicians and the American Academy of Family Practice again endorsing these guidelines.⁸ ACOG, ACS, NCCN, and ACR continued to recommend age 40 as a starting age for routine mammography screening (TABLE 2). As a result, over the past 14 years, patients aged 40 to 49 were placed in an awkward position of potentially hearing different recommendations from their health care providers, those differences often depending on the specialty of the provider they were seeing. 

In 2023. On May 9, the USPSTF released a draft of their latest recommendation statement stating that all patients at average risk for breast cancer should get screened every other year beginning at age 40, bringing most of the national guideline groups into alignment with regard to age to start mammographic screening.⁹ 

Why the change? 

To answer this question, we need to examine the relevant epidemiology of breast cancer. 

Continue to: Incidence...

Incidence

It is estimated that, in the United States in 2023, there will be 300,590 new cases of breast cancer, resulting in 43,700 deaths.¹⁰ From 2015–2019, there were 128.1 new breast cancer cases/100,000 population, which is the highest rate of cancer in the United States, regardless of sex.¹¹ Diagnoses among patients aged 40 to 49 are rising at a faster rate than previously, about 2% per year between 2015 and 2019. 

Racial and ethnic differences

In addition to the racial and ethnic epidemiologic differences in breast cancer, there are also disparities in breast cancer care and outcomes that need to be considered when making national guidelines/policy recommendations. 

Black women have high mortality rates from breast cancer. While non-Hispanic White patients have the highest rates of breast cancer (TABLE 3), non-Hispanic Black patients have the highest rates of death due to breast cancer.¹⁰ There appear to be several reasons for the estimated 40%-higher rate of mortality among Black women, including: 

• systemic racism in primary research, guidelines, and policy
• inequities in diagnostic follow-up and access to evidence-based cancer treatments
• biologic differences in breast cancer (ie, the incidence of triple-negative breast cancer (TNBC) is 2-fold higher in Black women compared with the other racial and ethnic groups in the United States).^12-14 

While prior studies have suggested that screening mammography might be less effective for patients with TNBC, a recent study demonstrated that patients who had mammography–screened-detected TNBC tumors were smaller and more likely to be node- negative compared with non-screened patients with TNBC.(14) Patients with screened-detected TNBCs were also more likely to undergo a lumpectomy instead of a mastectomy compared with non–screened detected TNBC (68.3% vs 46.1%; P = .002) (TABLE 4). These data strongly suggest that screening mammography is indeed effective in detecting TNBC at earlier stages, one of the best proxies for breast cancer mortality. 

Non-White patients have higher incidence rates of breast cancer in their 40s. A second factor to consider in racial differences is the relatively higher incidence of breast cancer in Hispanic, Black, and Asian patients in their 40s compared with non-Hispanic White patients. In a recent analysis of data from 1973 to 2010 from the Surveillance, Epidemiology, and End Results (SEER) Program, the median age of patients with breast cancer in the United States was 58.0 years (interquartile range [IQR], 50.0–67.0 years).¹⁶ Across all US demographic populations by age at diagnosis, more than 20% of patients will have their initial diagnosis of  breast cancer under the age of 50, and 1.55% (1 in 65) patients between ages 40 and 49 years will be diagnosed with breast cancer.4 However, among patients aged 50 and younger diagnosed with breast cancer, a significantly higher proportion are Black (31%), Hispanic (34.9%), or Asian (32.8%) versus White (23.1%) (P < .001 for all).¹⁶ So, for there to be similar racial and ethnic mammography capture rates with White patients, starting mammography screening ages would need to be lower for Black (age 47 years), Hispanic (and 46 years), and Asian (age 47 years) patients. Data from this study of the SEER database16 also demonstrated that more Black and Hispanic patients at age of diagnosis were diagnosed with advanced (regional or distant) breast cancer (46.6% and 42.9%, respectively) versus White or Asian patients (37.1% and 35.6%, respectively; P < .001 for all). 

These findings led the authors of the study to conclude that the “Current [2016] USPSTF breast cancer screening recommendations do not reflect age-specific patterns based on race.” The USPSTF stated that this is one of the reasons why they reconsidered their stance on screening , and now recommend screening for all patients starting at age 40. 

My current counseling approach

I encourage all racial and ethnic patients between the ages of 40 and 49 to undergo screening mammography because of the associated relative risk mortality reduction rates, which range from 15% to 50%. I also share that with my patients that, because of the younger average age of onset of breast cancer in Black, Hispanic, and Asian patients, they may derive additional benefit from screening starting at age 40.⁴ 

Impact of draft guidelines on breast cancer screening and mortality in younger patients

There is clear, unequivocal, and repeatable Level 1 evidence that screening mammography in the general population of patients aged 40 to 49 reduces breast cancer mortality. Breast cancer is the leading cause of cancer in the United States, the second leading cause of cancer mortality in patients, and 1 in 5 new breast cancer diagnoses occur in patients between the ages of 40 and 49. While recent efforts have been made to come to consensus on a screening starting age of 40 for patients at average risk for breast cancer, the USPSTF appeared to be an outlier with their 2016 recommendation to routinely start mammography screening at age 50 instead of 40.¹⁷ 

The USPSTF is a very important national voice in cancer prevention, and their 2023 (draft) revised guidelines to age 40 as the recommended starting screening age now agrees with the leading US guideline groups listed in Table 2. These guideline groups have gone through varying processes, and now have finally arrived at the same conclusion for age to start screening mammography in women of average risk. This agreement should come as a significant comfort to health care providers and patients alike. Changing the starting age to 40 years will result in thousands of lives and hundreds of thousands of life-years saved for patients aged 40 to 49. ● 

The US Preventive Services Task Force (USPSTF)¹ is comprised of an independent panel of preventive services clinician experts who make evidence-based recommendations, with the letter grade assigned based on the strength of the evidence, from A through D (TABLE 1), on preventive services such as health screenings, shared decision making patient counseling, and preventive medications.  Both A and B recommendations are generally accepted by both government and most private health insurance companies as a covered preventive benefit with no or minimal co-pays.

In 2002, the USPSTF released a Grade B recommendation that screening mammography for average-risk patients (with patients referring to persons assigned female at birth who have not undergone bilateral mastectomy) should take place starting at age 40 and be repeated every 1 to 2 years.² This was consistent with or endorsed by most other national breast cancer screening guidelines,  including the American College of Obstetricians and Gynecologists (ACOG), National Comprehensive Cancer Network (NCCN), the American Cancer Society (ACS), and the American College of Radiology. 

In 2009, the USPSTF changed this Grade B recommendation, instead recommending biennial screening mammography for women aged 50 to 74.³ The most significant change in the revised guideline was for patients aged 40 to 49, where the recommendation was “against routine screening mammography.” They went on to say that the decision to start “biennial screening mammography before the age of 50 years should be an individual one and take patient context into account, including the patient’s values regarding specific benefits and harms.” Other prominent national guideline groups (ACOG, NCCN, ACS) did not agree with this recommendation and maintained that patients aged 40 to 49 should continue to be offered routine screening mammography either annually (NCCN, ACS) or at 1-to-2-year intervals (ACOG).^4-6 The American College of Physicians and the American Academy of Family Practice endorsed the 2016 USPSTF guidelines, creating a disparity in breast cancer mammography counseling for averagerisk patients in their 40s.⁷

In 2016, the USPSTF revisited their breast cancer screening recommendation and renewed their 2009 recommendation against routine screening in patients aged 40 to 49, with the American College of Physicians and the American Academy of Family Practice again endorsing these guidelines.⁸ ACOG, ACS, NCCN, and ACR continued to recommend age 40 as a starting age for routine mammography screening (TABLE 2). As a result, over the past 14 years, patients aged 40 to 49 were placed in an awkward position of potentially hearing different recommendations from their health care providers, those differences often depending on the specialty of the provider they were seeing. 

In 2023. On May 9, the USPSTF released a draft of their latest recommendation statement stating that all patients at average risk for breast cancer should get screened every other year beginning at age 40, bringing most of the national guideline groups into alignment with regard to age to start mammographic screening.⁹ 

Why the change? 

To answer this question, we need to examine the relevant epidemiology of breast cancer. 

Continue to: Incidence...

Incidence

It is estimated that, in the United States in 2023, there will be 300,590 new cases of breast cancer, resulting in 43,700 deaths.¹⁰ From 2015–2019, there were 128.1 new breast cancer cases/100,000 population, which is the highest rate of cancer in the United States, regardless of sex.¹¹ Diagnoses among patients aged 40 to 49 are rising at a faster rate than previously, about 2% per year between 2015 and 2019. 

Racial and ethnic differences

In addition to the racial and ethnic epidemiologic differences in breast cancer, there are also disparities in breast cancer care and outcomes that need to be considered when making national guidelines/policy recommendations. 

Black women have high mortality rates from breast cancer. While non-Hispanic White patients have the highest rates of breast cancer (TABLE 3), non-Hispanic Black patients have the highest rates of death due to breast cancer.¹⁰ There appear to be several reasons for the estimated 40%-higher rate of mortality among Black women, including: 

• systemic racism in primary research, guidelines, and policy
• inequities in diagnostic follow-up and access to evidence-based cancer treatments
• biologic differences in breast cancer (ie, the incidence of triple-negative breast cancer (TNBC) is 2-fold higher in Black women compared with the other racial and ethnic groups in the United States).^12-14 

While prior studies have suggested that screening mammography might be less effective for patients with TNBC, a recent study demonstrated that patients who had mammography–screened-detected TNBC tumors were smaller and more likely to be node- negative compared with non-screened patients with TNBC.(14) Patients with screened-detected TNBCs were also more likely to undergo a lumpectomy instead of a mastectomy compared with non–screened detected TNBC (68.3% vs 46.1%; P = .002) (TABLE 4). These data strongly suggest that screening mammography is indeed effective in detecting TNBC at earlier stages, one of the best proxies for breast cancer mortality. 

Non-White patients have higher incidence rates of breast cancer in their 40s. A second factor to consider in racial differences is the relatively higher incidence of breast cancer in Hispanic, Black, and Asian patients in their 40s compared with non-Hispanic White patients. In a recent analysis of data from 1973 to 2010 from the Surveillance, Epidemiology, and End Results (SEER) Program, the median age of patients with breast cancer in the United States was 58.0 years (interquartile range [IQR], 50.0–67.0 years).¹⁶ Across all US demographic populations by age at diagnosis, more than 20% of patients will have their initial diagnosis of  breast cancer under the age of 50, and 1.55% (1 in 65) patients between ages 40 and 49 years will be diagnosed with breast cancer.4 However, among patients aged 50 and younger diagnosed with breast cancer, a significantly higher proportion are Black (31%), Hispanic (34.9%), or Asian (32.8%) versus White (23.1%) (P < .001 for all).¹⁶ So, for there to be similar racial and ethnic mammography capture rates with White patients, starting mammography screening ages would need to be lower for Black (age 47 years), Hispanic (and 46 years), and Asian (age 47 years) patients. Data from this study of the SEER database16 also demonstrated that more Black and Hispanic patients at age of diagnosis were diagnosed with advanced (regional or distant) breast cancer (46.6% and 42.9%, respectively) versus White or Asian patients (37.1% and 35.6%, respectively; P < .001 for all). 

These findings led the authors of the study to conclude that the “Current [2016] USPSTF breast cancer screening recommendations do not reflect age-specific patterns based on race.” The USPSTF stated that this is one of the reasons why they reconsidered their stance on screening , and now recommend screening for all patients starting at age 40. 

My current counseling approach

I encourage all racial and ethnic patients between the ages of 40 and 49 to undergo screening mammography because of the associated relative risk mortality reduction rates, which range from 15% to 50%. I also share that with my patients that, because of the younger average age of onset of breast cancer in Black, Hispanic, and Asian patients, they may derive additional benefit from screening starting at age 40.⁴

Key clinical point: Patients with chronic migraine have autonomic dysfunction, the extent of which is evaluated using heart rate variability (HRV) analysis, and a preserved function is associated with a superior response to flunarizine preventive treatment.

Major finding: Most heart-rate variability (HRV) parameters, except the ratios of low-frequency (LF) band and LF/high-frequency band, were significantly lower in patients with migraine vs control individuals (P < .001). The response to flunarizine treatment was superior in patients with normal HRV, as exemplified by higher reductions in monthly headache days after 3 months in those with normal vs lower HRV (─9.7 days vs ─6.2 days; P = .026).

Study details: This cross-sectional, prospective study included 81 prophylaxis-naive patients with chronic migraine and 58 age- and gender-matched control individuals. Patients with migraine initiated flunarizine as a preventive treatment for 12 weeks.

Key clinical point: The use of ubrogepant in combination with anti-calcitonin gene-related peptide (CGRP) monoclonal antibody (mAb) leads to meaningful pain relief (MPR), return to normal function (RNF), treatment satisfaction, and acute treatment optimization in patients with migraine.

Major finding: Following the first treated attack, 61.6% and 80.4% of patients achieved MPR and 34.7% and 55.5% of patients achieved RNF at 2 hours and 4 hours post-dose, respectively, in the ubrogepant plus anti-CGRP mAb arm. Moreover, 72.7% of patients reported being satisfied with ubrogepant when used in combination with anti-CGRP mAb, and 79.7% of patients achieved acute treatment optimization at 30 days.

Study details: Findings are from a prospective, observational study that included 245 patients with migraine who were treated with ubrogepant combined with anti-CGRP mAb, onabotulinumtoxinA, or both, for migraine prevention.

Disclosures: This study was funded by Allergan (prior to its acquisition by AbbVie). RB Lipton declared receiving research support, honoraria, and royalties from, and serving as a consultant and advisory board member for various sources, including AbbVie or Allergan.

Key clinical point: The introduction of calcitonin gene-related peptide (CGRP) monoclonal antibodies (mAb) has led to a reduction in the prescription of other oral preventive therapies for chronic migraine, likely due to the similar efficacy and better safety profile of CGRP mAb.

Major finding: Overall, the percentage of commonly prescribed preventive medications reduced significantly from 46.3% before the introduction of CGRP mAb to 43.1% post introduction (P = .001), including a large decrease in the prescription of verapamil, tricyclic antidepressants, topiramate, onabotulinumtoxinA, valproate, duloxetine, memantine, and propranolol (all P < .05).

Study details: This retrospective cohort study compared the percentage of patients with chronic migraine who were prescribed oral preventive medications or onabotulinumtoxinA during the CGRP mAb pre-approval period (2015-2017; n = 3144) and post-approval period (2019-2021; n = 4629).

Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.
