To see the harmful effects of climate change firsthand, you need look no farther than the nearest pulmonary clinic.

The causes and effects are unmistakable: pollen storms leading to allergy sufferers flooding into allergists’ offices; rising air pollution levels increasing risk for obstructive airway diseases, cardiopulmonary complications, and non–small cell lung cancer; melting snowpacks and atmospheric rivers inundating neighborhoods and leaving moldy debris and incipient fungal infections in their wake.

“The reason why we think climate change is going to change the type of disease patterns and the severity of illness that we see in patients with respiratory diseases is that it changes a lot of the environment as well as the exposures,” said Bathmapriya Balakrishnan, BMedSci, BMBS, from the section of Pulmonary, Critical Care, and Sleep Medicine in the department of medicine at West Virginia University, Morgantown.

“What we’re going to see is not just new diseases but also exacerbation of chronic diseases, things like asthma [and] COPD. And there’s also concern that patients who are otherwise healthy, because they now have more exposures that are due to climate change, can then develop these diseases,” she said in an interview.

Ms. Balakrishnan is the lead author of a comprehensive, evidence-based review focused on the effects of climate change and air pollution across the spectrum of pulmonary disorders. The review is published online ahead of print in the journal Chest.

“As pulmonologists, understanding and improving awareness of the adverse effects of climate change and air pollution are crucial steps. To inform health care providers of evidence-based methods and improve patient counselling, further research regarding measures that limit exposure is needed. Empowering patients with resources to monitor air quality and minimize exposure is a key preventative measure for decreasing morbidity and mortality while improving quality of  life,” Ms. Balakrishnan and colleagues write.

Similarly, in a statement on the effects of climate change on respiratory health, the American Public Health Association succinctly summarized the problem: “Warmer temperatures lead to an increase in pollutants and allergens. Poor air quality leads to reduced lung function, increased risk of asthma complications, heart attacks, heart failure, and death. Air pollution and allergens are the main exposures affecting lung and heart health in this changing climate.”
 

Early spring

Stanley Fineman, MD, MBA, a past president of the American College of Allergy, Asthma, & Immunology and an allergist in private practice in Atlanta, has seen firsthand how global warming and an earlier start to spring allergy season is affecting his patients.

“The season, at least in our area metro Atlanta, started earlier and has been lasting longer. The pollen counts are very high,” he told this news organization.

“In February we started seeing pollen counts over 1,000 [grams per cubic meter], which is unheard of, and in March about half the days we counted levels that were over 1,000, which is also unheard of. In April it was over 1,000 almost half the days.”

Dr. Fineman and colleagues both in Atlanta and across the country have reported sharp increases in the proportion of new adult patients and in existing patients who have experienced exacerbation of previously mild disease.

“Probably what’s happened is that they may have had some allergic sensitivity that resulted in milder manifestations, but this year they’re getting major manifestations,” Dr. Fineman said.

In a 2014 article in the journal European Respiratory Review, Gennaro D’Amato, MD, from High Speciality Hospital Antonio Cardarelli, Naples, Italy, and colleagues outlined the main effects of climate on pollen levels: “1) an increase in plant growth and faster plant growth; 2) an increase in the amount of pollen produced by each plant; 3) an increase in the amount of allergenic proteins contained in pollen; 4) an increase in the start time of plant growth and, therefore, the start of pollen production; 5) an earlier and longer pollen season; 6) change in the geospatial distribution of pollen, that is plant ranges and long-distance atmospheric transport moving polewards,” they write.
 

Bad air

In addition to pollen, the ambient air in many places is increasingly becoming saturated with bioallergenic proteins such as bacteria, viruses, animal dander, insects, molds, and plant species, Ms. Balakrishnan and colleagues noted, adding that “atmospheric levels of carbon dioxide have also been found to increase pollen productivity. These changes result in greater over-the-counter medication use, emergency department visits, and outpatient visits for respiratory illnesses.”

The rash of violent storms that has washed over much of the United States in recent months is also likely to increase the incidence of so-called “thunderstorm asthma,” caused when large quantities of respirable particulate matter are released before or during a thunderstorm.

Air pollution from the burning of carbon-based fuels and from wildfires sparked by hotter and drier conditions increase airborne particulate matter that can seriously exacerbate asthma, COPD, and other obstructive airway conditions.

In addition, as previously reported by Medscape, exposure to particulate matter has been implicated as a possible cause of non–small cell lung cancer in persons who have never smoked.
 

Critical care challenges

Among the myriad other effects of climate change postulated in evidence enumerated by Ms. Balakrishnan and colleagues are chest infections and pleural diseases, such as aspergillosis infections that occur after catastrophic flooding; increased incidence of Mycobacterium avium complex infections and hypersensitivity pneumonitis; increased demands on critical care specialists from natural disasters; pollution-induced cardiac arrest; and heat prostration and heat stroke from increasingly prevalent heat waves.

The reviewers also examined evidence suggesting links between climate change and pulmonary hypertension, interstitial lung disease, sleep disorders, and occupational pulmonary disorders.
 

Power to the patients

“Pulmonologists should counsel patients on ways to minimize outdoor and indoor pollution, using tight-fitting respirators and home air-purifying systems without encroaching on patients’ beliefs and choices,” the authors advise.

“Empowering patients with resources to monitor air quality daily, in inclement weather, and during disasters would help minimize exposure and thus improve overall health. The pulmonologist can play an important role in emphasizing the impact of climate change on pulmonary disorders during patient care encounters,” they write.

Ms. Balakrishan adds that another important mitigation measure that can be taken today is education.

“In medical school we don’t really learn about the impact of climate change – at least in my generation of physicians, climate change or global warming weren’t part of the medical curriculum – but now I think that there’s a lot of advocacy work being done by medical students who actually want more education on climate change and its effects on pulmonary diseases,” she said.

The study by Ms. Balakrishnan and colleagues was unfunded. Ms. Balakrishnan reports no relevant financial relationships. Co-author Mary-Beth Scholand, MD, has received personal fees from serving on advisory boards and speakers bureaus for Genentech, Boehringer Ingelheim, Veracyte, and United Therapeutics. Co-author Sean Callahan, MD, has received personal fees for serving on advisory boards for Gilead and Boehringer Ingelheim. Dr. Fineman reports no relevant financial relationships.

While they’re much less likely to develop chronic lymphocytic leukemia (CLL) than are White patients, African-American patients with this blood cancer are detected later and die sooner from the disease, a new study shows.

The findings, published in the American Journal of Hematology, hint that the racial disparity has shrunk over time, especially within the first few years of the targeted-therapy era. Still, “Black patients had a shorter median overall survival of 7 years compared to 9 years for White patients,” study coauthor Deborah Stephens, DO, of the University of Utah Huntsman Cancer Institute, said in an interview. “Clearly, more research is needed to tease out the biologic or economic barriers to achieving prolonged survival.”

As the researchers noted, CLL is far more common among White patients (5.1 cases per 100,000) than other races (Black patients: 3.2 cases per 100,000; Hispanic patients: 2.1 cases per 100,000; Asian American patients: 1.1 per 100,000). In total, non-White patients make up just 11%-13% of CLL cases in the United States.

According to Dr. Stephens, “little is known or published” about Black patients with CLL, “and it is still a mystery why fewer patients that are Black develop CLL and why this group would have shorter survival.”

Dr. Stephens and colleagues launched the new study – the largest of its kind to date – to understand disparities between White and Black patients over most of the past 20 years. The researchers especially wanted to analyze trends during the last decade, when targeted therapies revolutionized treatment of the disease.

The study authors analyzed data in the National Cancer Database for 97,804 patients diagnosed from 2004 to 2018 (90.7% White, 7.6% Black, 0.6% Asian, 1.1% other). Of patients who reported ethnicity (n = 93,555), 2.6% were Hispanic.

Black patients were more likely to have begun CLL therapy at diagnosis (35.9%) than were White patients (23.6%), a sign that Black patients had more advanced disease. Black patients also had shorter overall survival (7.0 years, 95% confidence interval [CI], 6.7–7.3 years) vs. White patients (9.1 years, 95% CI, 9.0–9.3 years, P < .001).

“This finding could be due to underlying biologic differences in the pathology of CLL, when comparing patients across racial groups,” Dr. Stephens said. “Additionally, there could be differences in access to care. Notably, there are fewer racial minorities enrolled in clinical trials, and perhaps we are not individualizing therapy for unique biologic factors seen in CLL affecting racial minorities.”

Other factors also could be at play. Black patients were more likely than were White patients to have one or more comorbidities (27.9% vs. 21.3%, P < .001), lack insurance (6.6% vs. 2.1%, P < .001) and live in lower-income neighborhoods (47.7% vs. 13.1%, P < .001).

What explains the gap in outcomes? In an interview, study lead author Victoria Vardell, MD, of the University of Utah, Salt Lake City, noted that researchers often attribute worse medical outcomes in Black patients to economic and social disparities.

“However, when we adjusted for a number of surrogate markers of health care access, including income, comorbidities, and location, among others, this disparity remained. That indicates that this may be a more complex problem in CLL in particular. Certainly, we cannot adjust for all the socioeconomic strain placed on Black Americans, including those with CLL, but there may be molecular features related to ancestry or environmental exposures that also play a role,” Dr. Vardell said.

She added that “the high cost and difficulty obtaining many novel therapies, particularly in the clinical trial setting, places significantly higher burdens on already disadvantaged populations.”

There is some good news in the new report. “Promisingly, our data suggest that the survival disparity between White and Black patients with CLL may be improving, particularly within the last 5 years, though longer follow-up is needed to confirm significance,” the researchers reported.

Alessandra Ferrajoli, MD, of M.D. Anderson Cancer Center, Houston, who has studied racial disparities in CLL, praised the study in an interview. As she noted, it examines an impressively large population.

The explanations for the disparities are still elusive, she said, although it seems clear there are multiple factors at play. “We don’t know if the disease has the same characteristics in African-Americans as in Whites,” Dr. Ferrajoli said. However, she noted, there’s “no indication that the response to treatment is different according to race.”

Moving forward, she said, the study findings “reinforce the fact that we need to pay attention to this population and be quite attentive to their characteristics.”

No study funding was reported. The authors and Dr. Ferrajoli have no disclosures.

Moving forward, she said, the study findings “reinforce the fact that we need to pay attention to this population and be quite attentive to their characteristics.”

No study funding was reported. The authors and Dr. Ferrajoli have no disclosures.

CHICAGO – Improving access to preventive health care services, such as colorectal cancer screening, for the poor and uninsured has led to better health outcomes, shows a study presented on May 6 in Chicago at the annual Digestive Disease Week®.

Researchers from the University of California, Los Angeles, reported that states with expanded Medicaid coverage had significantly higher rates of colorectal cancer (CRC) screening than states where officials refused federal support for Medicaid expansion.

Led by Megan R. McLeod, MD, an internal medicine resident at the University of California, Los Angeles, researchers compared CRC screening rates in states that did not adopt Medicaid expansion in 2021 with screening rates in states that invested Medicaid expansion into 1,284 Federally Qualified Health Centers, which are nonprofit health centers or clinics that serve medically underserved areas and populations. In this study, 76% of these centers were in states that accepted Medicaid expansion. The median colorectal cancer screening rate was 42.1% in Medicaid expansion states, compared with 36.5% in nonexpansion states

“The impact of being uninsured on CRC screening participation was profound in nonexpansion states,” said Dr. McLeod, who will be a UCLA gastroenterology fellow this year.

The study adds to a growing body of evidence that shows Medicaid expansion, which increases access to health care services to previously uninsured or underinsured patients, can improve health outcomes and may reduce racial and economic disparities.

For example, a 2019 study based on electronic health record data presented at the annual meeting of the American Society of Clinical Oncology showed that, after Medicaid expansion, racial differences in timely cancer treatment effectively disappeared. Before Medicaid expansion, Black patients were 4.8% less likely than White patients to receive timely cancer treatment, which is defined as treatment starting within 30 days of the diagnosis of an advanced or metastatic solid tumor. After Medicaid expansion, however, the difference between the racial groups dwindled to 0.8% and was no longer statistically significant.

Researchers at Weill Cornell Medical Center in New York reported in 2020 at the virtual annual meeting of the American Association for the Study of Liver Diseases that, 1 year after Medicaid expansion began on Jan. 1, 2014, the rate of liver-related mortality began to decline in 18 states with expanded coverage, whereas the rate of liver-related deaths continued to climb in 14 states that did not expand Medicaid.

The U.S. Health Resources and Services Administration funds Federally Qualified Health Centers (FQHC) that serve nearly 29 million patients throughout the country, including a large proportion whose care is covered by Medicaid. Among patients cared for in these centers, one in three have incomes below the federal poverty line, and one in five are uninsured.

Screening rates compared

Dr. McLeod and colleagues sought to determine whether Medicaid expansion would have an effect on CRC screening rates at these centers. The final analysis included 6,940,879 patients (between 50 and 74 years), of whom 1.7% were unhoused and 17.6% were uninsured.

Medicaid expansion status appeared to have a direct impact on whether screenings were even offered to patients. Centers in rural areas and those with a high proportion of uninsured patients were found to have significantly higher odds for doing fewer CRC screenings. In Medicaid expansion states, CRC screening rates were significantly lower for patients who were male, Black, Hispanic, had low income, were unhoused, or were uninsured.

In a Q&A that followed the presentation, Steven Itzkowitz, MD, director of the GI fellowship program at the Icahn School of Medicine at Mount Sinai, New York, suggested the type of CRC test patients are offered is directly related to Medicaid expansion status.

“In New York, before Cologuard (a colon and rectal cancer screening test) was covered by Medicaid, it wasn’t used very much, but once it got paid for by Medicaid, rates went up,” he said.

The study was internally supported. Dr. McLeod reported no conflicts of interest. Dr. Itzkowitz has been a consultant for Exact Sciences, the maker of Cologuard.

Certain relatives of women with early onset breast cancer appear to face an increased risk of other early-onset cancers, a Finnish population-based study suggests.

The researchers found, for instance, that children of breast cancer patients had a 27% higher risk of any discordant early-onset cancer, and patients’ siblings had a 7.6-fold higher risk of early pancreatic cancer. The analysis also indicated that children of patients’ siblings had a significantly increased risk of testicular and ovarian cancers.

“The findings suggest that the familial risk extends to discordant early-onset cancers, including ovarian, testicular, and pancreatic cancers, as well as beyond first-degree relatives,” the researchers, led by Janne M. Pitkäniemi, PhD, Finnish Cancer Registry, Institute for Statistical and Epidemiological Cancer Research, Helsinki, say. “Our findings are interesting but raise some questions about unknown [genetic] and environmental mechanisms that need to be further studied.”

Erin F. Cobain, MD, who was not involved in the research, said the findings are “not very surprising to me.”

Dr. Cobain said that at her institution, she has seen “many, many cases” of family members of early-onset breast cancer patients with discordant cancers “where we are unable to find a clear genetic cause.”

Not being able to find an identifiable cause for the clustering of early-onset cancers can be “very frustrating” for patients and their families, said Dr. Cobain, a medical oncologist at the University of Michigan Health, Ann Arbor.

The study was published online in the International Journal of Cancer.

Family members of patients with early-onset breast cancer are at elevated risk for early-onset breast cancer. However, it is “unclear whether the familial risk is limited to early-onset cancer of the same site,” the authors explained.

To investigate, the researchers studied data from the Finnish Cancer Registry and the Finnish Population System, which included 54,753 relatives from 5,562 families of females diagnosed with early-onset breast cancer, defined as probands. A proband was the first member of the family diagnosed with female breast cancer at age 40 years or younger in Finland between January 1970 and December 31, 2012. Cancers were considered familial if they occurred in a family with a previously diagnosed proband and were deemed early onset if diagnosed before age 41.

The researchers found that only 5.5% of probands’ families had a family member with a discordant early-onset cancer. The most common diagnoses were testicular cancer (0.6% of families) and cancer of the thyroid gland (also 0.6%), followed by melanoma (0.5%).

Overall, the risk of any nonbreast early-onset cancer among first-degree relatives of probands was comparable with the risk in the general population (standardized incidence ratio, 0.99; 95% confidence interval, 0.84-1.16).

However, the risk was elevated for certain family members and certain cancers.

Specifically, the children of probands had an increased risk for any discordant cancer (SIR, 1.27; 95% CI, 1.05-1.55).

The siblings of probands had an elevated risk for early-onset pancreatic cancer (SIR, 7.61) but not overall for any discordant cancer (SIR, 0.93; 95% CI, 0.68-1.25).

And siblings’ children faced an elevated risk for testicular (SIR, 1.74) and ovarian (SIR, 2.69) cancer, though not of any discordant cancer (SIR, 1.16; 95% CI, 0.97-1.37).

The researchers also found that the fathers (SIR, 0.43), mothers (SIR, 0.48), and spouses (SIR, 0.58) of probands appeared to have a decreased risk of any discordant early-onset cancer.

A potential limitation to the study was that the authors could not identify individuals with hereditary cancer syndromes or concerning gene mutations, such as BRCA carriers, because “registry data do not include comprehensive information on the gene mutation carriage status.” But the authors note that the number of BRCA carriers is likely low because of the low number of ovarian cancers observed in first-degree relatives of probands.

Dr. Cobain noted as well that the current study is potentially limited by its “very homogeneous” cohort.

But, overall, the findings indicate that familial risk is often “a much more complicated problem, mathematically and statistically,” than were there a single genetic culprit, Dr. Cobain said. One possibility is that some shared environmental exposure may be increasing the cancer risk among members of the same family.

“Genetic diversity is so vast and understanding how the interplay of multiple genes can influence an individual’s cancer risk is so much more complicated than a single BRCA1 mutation that clearly influences your breast cancer risk,” she added. However, “we’re starting to get there.”

The study was funded by the Cancer Foundation Finland and Academy of Finland. The authors and Dr. Cobain had no relevant financial relationships to declare.

People with asthma have an elevated risk for a variety of cancers other than lung cancer, including melanoma as well as blood, kidney, and ovarian cancers, new research suggests.

But, the authors found, treatment with an inhaled steroid may lower that risk, perhaps by keeping inflammation in check.

“Using real-world data, our study is the first to provide evidence of a positive association between asthma and cancer risk in United States patients,” Yi Guo, PhD, with the University of Florida, Gainesville, said in a news release.

The study was published online in Cancer Medicine.

The relationship between chronic inflammation and cancer remains a key area of exploration in cancer etiology. Data show that the risk for developing cancer is higher in patients with chronic inflammatory diseases, and patients with asthma have complex and chronic inflammation. However, prior studies exploring a possible link between asthma and cancer have yielded mixed results.

To investigate further, Dr. Guo and colleagues analyzed electronic health records and claims data in the OneFlorida+ clinical research network for roughly 90,000 adults with asthma and a matched cohort of about 270,000 adults without asthma.

Multivariable analysis revealed that adults with asthma were more likely to develop cancer, compared with peers without asthma (hazard ratio, 1.36), the investigators found.

Adults with asthma had an elevated cancer risk for five of the 13 cancers assessed, including melanoma (HR, 1.98), ovarian cancer (HR, 1.88), lung cancer (HR, 1.56), kidney cancer (HR, 1.48), and blood cancer (HR, 1.26).

Compared with adults without asthma, those with asthma who did not treat it with an inhaled steroid had a more pronounced overall cancer risk, compared with those who were on an inhaled steroid (HR, 1.60 vs. 1.11).

For specific cancer types, the risk was elevated for nine of 13 cancers in patients with asthma not taking an inhaled steroid: prostate (HR, 1.50), lung (HR, 1.74), colorectal (HR, 1.51), blood (HR, 1.44), melanoma (HR, 2.05), corpus uteri (HR, 1.76), kidney (HR, 1.52), ovarian (HR, 2.31), and cervical (HR, 1.46).

In contrast, in patients with asthma who did use an inhaled steroid, an elevated cancer risk was observed for only two cancers, lung cancer (HR, 1.39) and melanoma (HR, 1.92), suggesting a potential protective effect of inhaled steroid use on cancer, the researchers said.

Although prior studies have shown a protective effect of inhaled steroid use on some cancers, potentially by reducing inflammation, the “speculative nature of chronic inflammation (asthma as a common example) as a driver for pan-cancer development requires more investigation,” Dr. Guo and colleagues cautioned.

And because of the observational nature of the current study, Dr. Guo’s team stressed that these findings do not prove a causal relationship between asthma and cancer.

“More in-depth studies using real-word data are needed to further explore the causal mechanisms of asthma on cancer risk,” the researchers concluded.

Funding for the study was provided in part by grants to the researchers from the National Institutes of Health, National Cancer Institute, National Institute on Aging, and the Centers for Disease Control and Prevention. This project was supported by the Cancer Informatics Shared Resource in the University of Florida Health Cancer Center. The authors have disclosed no conflicts of interest.

“Using real-world data, our study is the first to provide evidence of a positive association between asthma and cancer risk in United States patients,” Yi Guo, PhD, with the University of Florida, Gainesville, said in a news release.

The study was published online in Cancer Medicine.

The relationship between chronic inflammation and cancer remains a key area of exploration in cancer etiology. Data show that the risk for developing cancer is higher in patients with chronic inflammatory diseases, and patients with asthma have complex and chronic inflammation. However, prior studies exploring a possible link between asthma and cancer have yielded mixed results.

To investigate further, Dr. Guo and colleagues analyzed electronic health records and claims data in the OneFlorida+ clinical research network for roughly 90,000 adults with asthma and a matched cohort of about 270,000 adults without asthma.

Multivariable analysis revealed that adults with asthma were more likely to develop cancer, compared with peers without asthma (hazard ratio, 1.36), the investigators found.

Adults with asthma had an elevated cancer risk for five of the 13 cancers assessed, including melanoma (HR, 1.98), ovarian cancer (HR, 1.88), lung cancer (HR, 1.56), kidney cancer (HR, 1.48), and blood cancer (HR, 1.26).

Compared with adults without asthma, those with asthma who did not treat it with an inhaled steroid had a more pronounced overall cancer risk, compared with those who were on an inhaled steroid (HR, 1.60 vs. 1.11).

For specific cancer types, the risk was elevated for nine of 13 cancers in patients with asthma not taking an inhaled steroid: prostate (HR, 1.50), lung (HR, 1.74), colorectal (HR, 1.51), blood (HR, 1.44), melanoma (HR, 2.05), corpus uteri (HR, 1.76), kidney (HR, 1.52), ovarian (HR, 2.31), and cervical (HR, 1.46).

In contrast, in patients with asthma who did use an inhaled steroid, an elevated cancer risk was observed for only two cancers, lung cancer (HR, 1.39) and melanoma (HR, 1.92), suggesting a potential protective effect of inhaled steroid use on cancer, the researchers said.

Although prior studies have shown a protective effect of inhaled steroid use on some cancers, potentially by reducing inflammation, the “speculative nature of chronic inflammation (asthma as a common example) as a driver for pan-cancer development requires more investigation,” Dr. Guo and colleagues cautioned.

And because of the observational nature of the current study, Dr. Guo’s team stressed that these findings do not prove a causal relationship between asthma and cancer.

“More in-depth studies using real-word data are needed to further explore the causal mechanisms of asthma on cancer risk,” the researchers concluded.

Funding for the study was provided in part by grants to the researchers from the National Institutes of Health, National Cancer Institute, National Institute on Aging, and the Centers for Disease Control and Prevention. This project was supported by the Cancer Informatics Shared Resource in the University of Florida Health Cancer Center. The authors have disclosed no conflicts of interest.

Young patients with breast cancer can safely interrupt adjuvant endocrine therapy to attempt pregnancy without increasing their risk of breast cancer recurrence or new contralateral breast cancer.

The results provide the “strongest evidence to date on the short-term safety of this choice,” Sharon Giordano, MD, MPH, with University of Texas M.D. Anderson Cancer Center, Houston, wrote in an editorial accompanying the study.

“Physicians should now incorporate these positive data into their shared decision-making process with patients,” Dr. Giordano said.

The POSITIVE trial findings were published online  in The New England Journal of Medicine.

Before the analysis, the risks associated with taking a break from endocrine therapy among young women with hormone receptor (HR)–positive breast cancer remained unclear.

In the current trial, Ann Partridge, MD, MPH, and colleagues sought prospective data on the safety associated with taking a temporary break from therapy to attempt pregnancy.

The single-group trial enrolled more than 500 premenopausal women who had received 18-30 months of endocrine therapy for mostly stage I or II HR-positive breast cancer. After a 3-month washout, the women were given 2 years to conceive, deliver, and breastfeed, if desired, before resuming treatment. Breast cancer events – the primary outcome – were defined as local, regional, or distant recurrence of invasive breast cancer or new contralateral invasive breast cancer.

The results, initially reported at San Antonio Breast Cancer Symposium (SABCS) 2022, showed that a temporary interruption of therapy to attempt pregnancy did not appear to lead to worse breast cancer outcomes.

Among 497 women who were followed for pregnancy status, 368 (74%) had at least one pregnancy, and 317 (64%) had at least one live birth.

After a median follow-up of 3.4 years, 44 women had had a breast cancer event – a result that was close to, but did not exceed, the safety threshold of 46 breast cancer events.

The 3-year incidence of breast cancer events was 8.9% (95% confidence interval [CI], 6.3-11.6) in the treatment-interruption group compared with 9.2% (95% CI, 7.6-10.8) among historical controls, which included women who would have met the entry criteria for the trial.

“These results suggest that although endocrine therapy for a period of 5-10 years substantially improves disease outcomes in patients with hormone receptor–positive early breast cancer, a temporary interruption of therapy to attempt pregnancy does not appear to have an appreciable negative short-term effect,” wrote Dr. Partridge, vice chair of medical oncology at Dana-Farber Cancer Institute and professor of medicine at Harvard Medical School, Boston, and colleagues.

The authors cautioned, however, that the median follow-up was only 3.4 years and that 10-year follow-up data will be “critical” to confirm the safety of interruption of adjuvant endocrine therapy.

Dr. Giordano agreed, noting that “recurrences of breast cancer are reported to occur at a steady rate for up to 20 years after diagnosis among patients with hormone receptor–positive disease; the protocol-specified 10-year follow-up data will be essential to establish longer-term safety.”

The study was supported by the International Breast Cancer Study Group and by the Alliance for Clinical Trials in Oncology in North America in collaboration with the Breast International Group (BIG). Disclosures for authors and editorial writer are available at NEJM.org.

Treating Helicobacter pylori infection markedly reduces the risk for stomach cancer, a large study from Kaiser Permanente Northern California demonstrates.

People with H. pylori who were treated had about a 63% lower risk of developing noncardia gastric adenocarcinoma (NCGA) after 8 years of follow-up, compared with peers with H. pylori who were not treated.

The U.S. data align with previous studies, conducted mostly in Asia, that found that treating the infection can reduce stomach cancer incidence.

The KPNC study shows the “potential for stomach cancer prevention in U.S. populations through H. pylori screening and treatment,” study investigator Dan Li, MD, gastroenterologist with the Kaiser Permanente Medical Group and Kaiser Permanente Division of Research in Oakland, Calif., said in an interview.

Judith Kim, MD, a gastroenterologist at NYU Langone Health in New York, who wasn’t involved in the research, said that the study is significant because “it is the first to show this effect in a large, diverse population in the U.S., where gastric cancer incidence is lower.”

The study was published online in Gastroenterology.
 

Top risk factor

About 30% of people in the United States are infected with H. pylori, which is the No. 1 known risk factor for stomach cancer, Dr. Li said.

The study cohort included 716,567 KPNC members who underwent H. pylori testing and/or treatment between 1997 and 2015.

Among H. pylori–infected individuals (based on positive nonserology test results), the subdistribution hazard ratio was 6.07 for untreated individuals and 2.68 for treated individuals, compared with H. pylori–negative individuals.

It’s not surprising that people who were treated for the infection still had a higher risk of NCGA than people who had never had the infection, Dr. Li said.

“This is likely because many people with chronic H. pylori infection had already developed some precancerous changes in their stomach before they were treated. This finding suggests that H. pylori ideally should be treated before precancerous changes develop,” he said.

When compared directly with H. pylori–positive/untreated individuals, the risk for NCGA in H. pylori–positive/treated individuals was somewhat lower at less than 8 years follow-up (sHR, 0.95) and significantly lower at 8+ years of follow-up (sHR, 0.37).

“After 7-10 years of follow-up, people with H. pylori who received treatment had nearly half the risk of developing stomach cancer as the general population,” Dr. Li said. “This is likely because most people infected with H. pylori in the general population are not screened nor treated. This highlights the impact screening and treatment can have.”

The data also show that cumulative incidence curves for H. pylori–positive/untreated and H. pylori–positive/treated largely overlapped during the first 7 years of follow-up and started to separate after 8 years.

At 10 years, cumulative NCGA incidence rates for H. pylori–positive/untreated, H. pylori–positive/treated, and H. pylori negative were 31.0, 19.7, and 3.5 per 10,000 persons, respectively (P < .0001).

This study shows that treating H. pylori reduces stomach cancer incidence in the United States, thus “filling an important research and knowledge gap,” Dr. Li said.

In the United States, Asian, Black, and Hispanic adults are much more likely to be infected with H. pylori, and they have a two- to threefold higher risk of developing stomach cancer, he noted.

“This suggests it may be reasonable to consider targeted screening and treatment in these high-risk groups. However, the optimal strategy for population-based H. pylori screening has not been established, and more research is needed to determine who should be screened for H. pylori and at what age screening should begin,” Dr. Li said.
 

Strong data, jury out on universal screening

For additional comment, this news organization reached out to Aaron Glatt, MD, a spokesperson for the Infectious Diseases Society of America and chief of infectious diseases and hospital epidemiologist at Mount Sinai South Nassau in Oceanside, N.Y.

The study shows that the treatment of H. pylori “absolutely will decrease your risk of certain types of gastric carcinoma down the line. It does take a while to show that, 7 years, but this study shows that very clearly,” Dr. Glatt said.

“People who have definitely been shown to have H. pylori should be treated,” Dr. Glatt said.

“I don’t think this study yet supports that everybody should be screened, but it does make sense that people who have upper GI symptoms consistent with H. pylori should be checked for H. pylori and then appropriately treated, he noted.

Routine screening for H. pylori is recommended in countries with high incidence of gastric cancer, but not in the United States, Dr. Kim noted.

“Given the risk reduction of cancer with H. pylori treatment, consideration should be made in the U.S. for asymptomatic individuals with a family history of gastric cancer or immigrants from high-incidence countries,” she added.

The study was funded by the Kaiser Permanente Northern California Community Health Research Grants Program, the Permanente Medical Group Delivery Science & Applied Research Program, and the Permanente Medical Group. Dr. Li, Dr. Glatt, and Dr. Kim have declared no relevant financial relationships.

SEATTLE – Radiofrequency ablation (RFA) appears safe and effective for the treatment of low-risk papillary thyroid microcarcinoma (PTMC), new data suggest.

RFA is increasingly gaining favor as a less-invasive alternative to surgery for patients with large, symptomatic, benign thyroid nodules in the United States and elsewhere and for the treatment of thyroid microcarcinomas in other countries, particularly South Korea and China.

Now, new findings from eight patients seen at the Mayo Clinic are the first to be reported for use of RFA for PTMC in the United States, Kharisa Rachmasari, MD, an endocrinology fellow at Mayo, said at the annual scientific & clinical congress of the American Association of Clinical Endocrinology.

Papillary thyroid cancers of 10 mm or less are the most common thyroid cancers, and their incidence is rising. They are commonly discovered incidentally in the setting of increased cross-sectional imaging. These tiny cancers are typically indolent, and they are associated with an excellent prognosis. In the United States, standard management is either surveillance or surgery, whereas RFA has been used in Europe and Asia for more than a decade, Dr. Rachmasari said.

“There has been some hesitancy when it comes to cancer, because there’s no guarantee that we can do it in such a clean way as is done with surgery, where you can actually confirm a negative margin in pathology. And the follow-up is easier as well. With RFA, the PTMC is still there, and you can only follow it with ultrasound, not biochemically with thyroglobulin or certain biomarkers,” she said in an interview.

Nonetheless, for these eight patients who underwent the procedure at Mayo’s ablation clinic, where interventional radiologists team up with endocrinologists, there were no serious adverse events, and no further interventions were required during 24 months of follow-up, she reported.

Asked to comment, session moderator Anupam Kotwal, MD, assistant professor in the division of diabetes, endocrinology and metabolism at the University of Nebraska, Omaha, said, “It’s very novel. We talk about balancing the comorbidities that come from treatment of thyroid cancer, but at the same time we want to treat it appropriately ... And of course, there are patient factors. Some may prefer to have the cancer completely out, while others are okay with watching and are against any cuts in their neck. This comes as kind of a middle ground.”

But, Dr. Kotwal added, “[Investigators] definitely need to do a bit more work, especially in the population that may be at higher risk of cancer spread, such as those with a family history of thyroid cancer. We still don’t know how autoimmune disease influences cancer progression.”

He said that if RFA is to be used for PTMC, “I think it has to be done at a center that specializes in multidisciplinary care of thyroid cancers where there are not only the experts in doing the RFA procedure but also surgical expertise, in case a complication does happen, like a vocal cord injury. Or if the cancer is growing, they can expedite getting the person that appropriate treatment.”
 

An alternative to waiting vs. surgery?

The eight patients were seen at Mayo Clinic between July 2020 and February 2023. All had papillary thyroid carcinoma that was confirmed cytologically via fine-needle biopsy and single lesions without lymph node metastasis. All patients had been offered RFA as an alternative to either surgery or active surveillance.

Seven patients were female, and one was male (mean age, 53 years). All were euthyroid at baseline, and two were receiving thyroid hormone therapy. The mean diameter of their nodules was 9.5 mm, and the mean volume was 0.3 mL.

For the first six patients, the procedure was conducted under general anesthesia; deep sedation was used for the next patient, and moderate sedation was used for the most recent. “As we learn more and gain more experience, patients nowadays have moderate sedation,” she explained.

The active tip size was 10 mm for five patients and 7 mm with three. The radiofrequency power that was delivered ranged from 25 to 45 watts. The median ablation duration was 6 minutes and ranged from 2 to 14.5. “Patients usually stay in the suite about half an hour, so it’s a quick procedure, and the patient can go home on the same day,” Dr. Rachmasari said.

Following the procedure, the ablated area increased in size during the first 3-6 months because the ablation was applied beyond the cancer margins in an attempt to ensure a negative margin, as is done surgically. By 18 months, the ablated area had shrunk and resolved.

All patients remained euthyroid in 18-24 months’ follow-up, none had any cervical adenopathy, and none required subsequent intervention.

No significant adverse events were observed during or after the RFA procedure. A few patients complained of erythema and soreness around the area of the procedure, but this resolved with over-the-counter analgesia.

Longer follow-up will be necessary to detect any recurrence, Dr. Rachmasari noted.

Dr. Kotwal pointed out that lack of reimbursement for RFA has contributed to the slow adoption of RFA overall for the treatment of thyroid nodules in the United States, but added, “I think that will change quickly, especially with more and more data coming out about large benign nodules ... I think at least from the benign nodule standpoint, with discussions happening at national meetings and societies, it should push the payers to cover.”

Overall, he said, “If you have a complication or it affects quality of life, all of those things add to the cost. So if you can use a procedure early on to prevent increasing size of either the big nodule or reduce the size of a big nodule, or even a small cancer, and give that person months or years, even if they ultimately need surgery, I think that’s still a benefit for their quality of life. But again, we have to take patient factors into account.”

SEATTLE – Radiofrequency ablation (RFA) appears safe and effective for the treatment of low-risk papillary thyroid microcarcinoma (PTMC), new data suggest.

RFA is increasingly gaining favor as a less-invasive alternative to surgery for patients with large, symptomatic, benign thyroid nodules in the United States and elsewhere and for the treatment of thyroid microcarcinomas in other countries, particularly South Korea and China.

Now, new findings from eight patients seen at the Mayo Clinic are the first to be reported for use of RFA for PTMC in the United States, Kharisa Rachmasari, MD, an endocrinology fellow at Mayo, said at the annual scientific & clinical congress of the American Association of Clinical Endocrinology.

Papillary thyroid cancers of 10 mm or less are the most common thyroid cancers, and their incidence is rising. They are commonly discovered incidentally in the setting of increased cross-sectional imaging. These tiny cancers are typically indolent, and they are associated with an excellent prognosis. In the United States, standard management is either surveillance or surgery, whereas RFA has been used in Europe and Asia for more than a decade, Dr. Rachmasari said.

“There has been some hesitancy when it comes to cancer, because there’s no guarantee that we can do it in such a clean way as is done with surgery, where you can actually confirm a negative margin in pathology. And the follow-up is easier as well. With RFA, the PTMC is still there, and you can only follow it with ultrasound, not biochemically with thyroglobulin or certain biomarkers,” she said in an interview.

Nonetheless, for these eight patients who underwent the procedure at Mayo’s ablation clinic, where interventional radiologists team up with endocrinologists, there were no serious adverse events, and no further interventions were required during 24 months of follow-up, she reported.

Asked to comment, session moderator Anupam Kotwal, MD, assistant professor in the division of diabetes, endocrinology and metabolism at the University of Nebraska, Omaha, said, “It’s very novel. We talk about balancing the comorbidities that come from treatment of thyroid cancer, but at the same time we want to treat it appropriately ... And of course, there are patient factors. Some may prefer to have the cancer completely out, while others are okay with watching and are against any cuts in their neck. This comes as kind of a middle ground.”

But, Dr. Kotwal added, “[Investigators] definitely need to do a bit more work, especially in the population that may be at higher risk of cancer spread, such as those with a family history of thyroid cancer. We still don’t know how autoimmune disease influences cancer progression.”

He said that if RFA is to be used for PTMC, “I think it has to be done at a center that specializes in multidisciplinary care of thyroid cancers where there are not only the experts in doing the RFA procedure but also surgical expertise, in case a complication does happen, like a vocal cord injury. Or if the cancer is growing, they can expedite getting the person that appropriate treatment.”
 

An alternative to waiting vs. surgery?

The eight patients were seen at Mayo Clinic between July 2020 and February 2023. All had papillary thyroid carcinoma that was confirmed cytologically via fine-needle biopsy and single lesions without lymph node metastasis. All patients had been offered RFA as an alternative to either surgery or active surveillance.

Seven patients were female, and one was male (mean age, 53 years). All were euthyroid at baseline, and two were receiving thyroid hormone therapy. The mean diameter of their nodules was 9.5 mm, and the mean volume was 0.3 mL.

For the first six patients, the procedure was conducted under general anesthesia; deep sedation was used for the next patient, and moderate sedation was used for the most recent. “As we learn more and gain more experience, patients nowadays have moderate sedation,” she explained.

The active tip size was 10 mm for five patients and 7 mm with three. The radiofrequency power that was delivered ranged from 25 to 45 watts. The median ablation duration was 6 minutes and ranged from 2 to 14.5. “Patients usually stay in the suite about half an hour, so it’s a quick procedure, and the patient can go home on the same day,” Dr. Rachmasari said.

Following the procedure, the ablated area increased in size during the first 3-6 months because the ablation was applied beyond the cancer margins in an attempt to ensure a negative margin, as is done surgically. By 18 months, the ablated area had shrunk and resolved.

All patients remained euthyroid in 18-24 months’ follow-up, none had any cervical adenopathy, and none required subsequent intervention.

No significant adverse events were observed during or after the RFA procedure. A few patients complained of erythema and soreness around the area of the procedure, but this resolved with over-the-counter analgesia.

BOSTON – Having a preoperative MRI scan does not help surgeons to reduce the likelihood of positive surgical margins when they are performing lumpectomy for early stage breast cancer, a new study concludes.

The current results suggest that MRI is “not useful to achieve this goal and not a productive use of health care resources,” said senior author Marissa Howard-McNatt, MD, director of the Breast Care Center, Wake Forest University, Winston-Salem, N.C.

“Researchers continue to look for better ways to assess margin status while the patient is still on the operating table,” she said, as a re-operation “can be traumatic.”

The study was presented at the annual meeting of the American Society of Breast Surgeons and was highlighted in a press briefing.

In the study, more than 630 patients with early stage breast cancer were randomly assigned to partial mastectomy with or without cavity shaving of the tumor margins, of whom 193 underwent MRI before their operation.

Although there was a difference in the rate of positive surgical margins before cavity shaving between patients who did and did not undergo MRI, the difference did not reach statistical significance.

“MRI exams are costly and potentially stressful for patients,” Dr. Howard-McNatt commented in a press statement. “The thought is that they will help physicians achieve negative margins during the initial surgery. However, our study shows this is simply not the case.”

Approached for comment, Mediget Teshome, MD, MPH, said, “In my practice, I primarily utilize MRI preoperatively to evaluate the extent of disease in cases where the information is not clear from mammogram and ultrasound.”

This may be when there is “discordance between the size of the malignancy or concern for chest wall or muscle involvement,” Dr. Teshome said in an interview.

MRI is also useful when there may be occult disease, such as in patients “with high suspicion for extensive intraductal component not evident on mammography and those who present with axillary metastasis and unknown breast primary,” as well as in high-risk patients with a genetic predisposition for breast cancer, she explained.

However, Dr. Teshome, an associate professor in the department of breast surgical oncology at the University of Texas MD Anderson Cancer Center, Houston, stressed that, “as with any test, it is important that preoperative MRI is performed with the specific intent to inform clinical decision-making in a meaningful way.”

“While it can provide a benefit in selected cases given its high sensitivity, MRI is associated with false positives and can also contribute to increased patient anxiety and additional procedures,” she cautioned.
 

Study details

Lumpectomy has become “a mainstay of breast cancer management, with safe and reliable outcomes as compared to mastectomy,” said Dr. Howard-McNatt, but it is associated with a higher rate of positive margins, of up to 27%.

She underlined that “re-excision surgery can contribute to greater morbidity, patient anxiety, poor cosmetic outcomes, and health care system overload,” and the desire to reduce re-operations has led to “much attention” being paid to preoperative imaging.

Their study set out to investigate the value of preoperative MRI in this regard, and for this they analyzed data on 631 women who had participated in two prior randomized trials (SHAVE1 and SHAVE2).

These women were randomly assigned to standard partial mastectomy with or without resection of cavity shave margins, with preoperative MRI performed prior to randomization in both trials at the surgeon’s discretion.

The median tumor size was 1.3 cm. An extensive intraductal component was identified in 32.8% of patients, 26.1% had palpable tumors, and 7% had invasive lobular histology. Neoadjuvant chemotherapy was administered in 6.5% of patients.

In all, 193 individuals underwent MRI. These women were less likely to have a positive surgical margin before resection of cavity shave margins, at 31.1% vs. 38.8% in those who did not have MRI, although the difference was not statistically significant (P = .073).

Multivariate analysis taking into account patient age, race, receipt of neoadjuvant chemotherapy, the presence of an extensive intraductal component, as well as histologic subtype and tumor size, revealed that MRI was not associated with a higher rate of negative surgical margins (P = .110).

However, it was shown that both tumor size (P = .040) and age (P = .032) were predictive of margin status.

It was notable that MRI use was associated with younger patient age, at a median of 63 years vs. 66 years, and smaller tumor size, at a median of 2.0 cm vs. 2.1 cm.

This latter finding “may be attributable to an inaccurate initial assessment of the extent of the actual tumor size for a variety of reasons,” Dr. Howard-McNatt commented. “For example, tumors may be discontinuous or have satellite lesions which may touch the edge of a specimen.”

The study was funded in part by the David and Katie Burke Fund for Breast Cancer Research, the Connecticut Breast Health Initiative, the Troy Cancer Program, Cleveland Clinic Akron General Operations, the Cleveland Clinic Akron General Foundation, the Lineberger Comprehensive Cancer Center, the Watson Clinic Center for Research, and LifeCycle. The study authors report no relevant financial relationships.

BOSTON – Older women who have had breast cancer frequently undergo annual surveillance mammography, even if there is only a small risk of their developing a second cancer or if they have other mortality risks associated with age and comorbidities. This ongoing annual surveillance with mammography may be doing more harm than good, warn researchers.

In a study that included almost 45,000 women who were aged 67 years or older when they were diagnosed with breast cancer, investigators found that patients commonly underwent annual mammographies.

“Even 10 years after their initial diagnosis ... about 40% of them were still getting surveillance mammography well into their 80s and 90s,” noted lead investigator Elizabeth Berger, MD, assistant professor of breast surgical oncology, Yale University, New Haven, Conn.

“Ongoing surveillance mammography in these patients may lead to overdiagnosis and overtreatment of cancers that potentially would not harm patients if left untreated,” Dr. Berger said.

“A positive or false positive finding may unnecessarily erode patient quality of life and incur costs to the patient and health care system without benefit,” she said. She added: “If an elderly woman is in poor health and has significant competing mortality risks compared to breast cancer, annual mammography may not be necessary.”

The research was presented at the annual meeting of the American Society of Breast Surgeons (ASBrS). The study was highlighted in a preview press briefing.

Speaking at the press briefing, Dr. Berger said that the “risks and benefits of surveillance mammography, including its downstream effects, should be considered by both patients and their doctors together to create a shared decision plan.” She acknowledged that the idea of skipping mammograms may be a sensitive one for patients.

She also shared what she described as “exciting news”: “We have just recently received funding from our geriatric group here at Yale to start to evaluate the potential benefits and harms of these surveillance mammographies.”

The aim is to evaluate false positive rates and the potential for overdiagnosis and overtreatment, “so stay tuned,” she added.

Approached for comment, Mediget Teshome, MD, MPH, said it was “not surprising to see the high rates of surveillance mammography, especially in the short term after treatment.”

She said in an interview that the results suggest that it “may be being overused,” given the low rates of second primary breast cancer and the “competing health concerns” of these women.

Overuse can, on the other hand, “definitely be a complex issue,” said Dr. Teshome, associate professor, department of breast surgical oncology, University of Texas MD Anderson Cancer Center, Houston.

“The goal of mammography screening is to identify breast cancer at an early stage,” she explained. She noted that because of the “competing mortality risk from other challenging and life-threatening health problems,” early-stage breast cancer “may not contribute significantly” to the overall mortality risk.

“In general, in this patient population, consideration should be given to stratifying based on an individual patient’s risk of breast cancer recurrence or new breast cancer, estimated life expectancy, as well as shared decision-making with the patient based on their goals of care.”
 

Study details

To examine the use of surveillance mammography and the risk of subsequent cancers among older women, Dr. Berger and her team used data from the Surveillance, Epidemiology, and End Results (SEER) registry to identify women aged 67 years or older who were diagnosed with a first nonmetastatic beast cancer between 2003 and 2007.

The patients were followed beginning 1 year after diagnosis until the occurrence of a second primary breast cancer, death, or the end of follow-up in 2017.

Data on 44,475 women were analyzed. Of those patients, 30% were older than 80 years. The majority (74%) of breast cancers were of stage I or II, and 72% were hormone receptor–positive (HR+).

Comorbid conditions were common; 55% of women had at least one, and 16% had three or more.

Life expectancy, determined on the basis of age, sex, and comorbidities, was estimated at less than 5 years for 26% of women. For 36% of patients, life expectancy was 6-10 years, and for 38%, it was longer than 10 years.

The cumulative incidence of developing a second primary breast cancer varied by life expectancy and the tumor’s molecular subtype.

The incidence was 3.7% among women with a life expectancy of less than 5 years, 4.9% among those expected to live 6-10 years, and 7.6% among those predicted to live more than 10 years.

Among women with a life expectancy of less than 5 years, the cumulative incidence of a second primary tumor was 4.0% among those with triple-negative breast cancer, vs. 3.0% among those with HR+ breast cancer.

Among patients whose life expectancy was more than 10 years, the cumulative incidence of a second primary tumor was 9.2% among women with triple-negative disease, vs. 7.0% among those with HR+ cancers.

The team found that it was common for women across all the groups to undergo mammography.

Among women with a life expectancy of 6-10 years, 82% underwent at least one mammogram, and 65% underwent five mammograms. Even among women with a life expectancy of less than 1 year, 51% underwent at least one mammogram within 12 months of death.

Among women with a life expectancy of less than 5 years, 68% of women had received a mammogram 1 year after treatment; 53% underwent three mammograms within 3 years after treatment.

No funding for the study was declared. The investigators have disclosed no relevant financial relationships.

The research was presented at the annual meeting of the American Society of Breast Surgeons (ASBrS). The study was highlighted in a preview press briefing.

Speaking at the press briefing, Dr. Berger said that the “risks and benefits of surveillance mammography, including its downstream effects, should be considered by both patients and their doctors together to create a shared decision plan.” She acknowledged that the idea of skipping mammograms may be a sensitive one for patients.

She also shared what she described as “exciting news”: “We have just recently received funding from our geriatric group here at Yale to start to evaluate the potential benefits and harms of these surveillance mammographies.”

The aim is to evaluate false positive rates and the potential for overdiagnosis and overtreatment, “so stay tuned,” she added.

Approached for comment, Mediget Teshome, MD, MPH, said it was “not surprising to see the high rates of surveillance mammography, especially in the short term after treatment.”

She said in an interview that the results suggest that it “may be being overused,” given the low rates of second primary breast cancer and the “competing health concerns” of these women.

Overuse can, on the other hand, “definitely be a complex issue,” said Dr. Teshome, associate professor, department of breast surgical oncology, University of Texas MD Anderson Cancer Center, Houston.

“The goal of mammography screening is to identify breast cancer at an early stage,” she explained. She noted that because of the “competing mortality risk from other challenging and life-threatening health problems,” early-stage breast cancer “may not contribute significantly” to the overall mortality risk.

“In general, in this patient population, consideration should be given to stratifying based on an individual patient’s risk of breast cancer recurrence or new breast cancer, estimated life expectancy, as well as shared decision-making with the patient based on their goals of care.”
 

Study details

To examine the use of surveillance mammography and the risk of subsequent cancers among older women, Dr. Berger and her team used data from the Surveillance, Epidemiology, and End Results (SEER) registry to identify women aged 67 years or older who were diagnosed with a first nonmetastatic beast cancer between 2003 and 2007.

The patients were followed beginning 1 year after diagnosis until the occurrence of a second primary breast cancer, death, or the end of follow-up in 2017.

Data on 44,475 women were analyzed. Of those patients, 30% were older than 80 years. The majority (74%) of breast cancers were of stage I or II, and 72% were hormone receptor–positive (HR+).

Comorbid conditions were common; 55% of women had at least one, and 16% had three or more.

Life expectancy, determined on the basis of age, sex, and comorbidities, was estimated at less than 5 years for 26% of women. For 36% of patients, life expectancy was 6-10 years, and for 38%, it was longer than 10 years.

The cumulative incidence of developing a second primary breast cancer varied by life expectancy and the tumor’s molecular subtype.

The incidence was 3.7% among women with a life expectancy of less than 5 years, 4.9% among those expected to live 6-10 years, and 7.6% among those predicted to live more than 10 years.

Among women with a life expectancy of less than 5 years, the cumulative incidence of a second primary tumor was 4.0% among those with triple-negative breast cancer, vs. 3.0% among those with HR+ breast cancer.

Among patients whose life expectancy was more than 10 years, the cumulative incidence of a second primary tumor was 9.2% among women with triple-negative disease, vs. 7.0% among those with HR+ cancers.

The team found that it was common for women across all the groups to undergo mammography.

Among women with a life expectancy of 6-10 years, 82% underwent at least one mammogram, and 65% underwent five mammograms. Even among women with a life expectancy of less than 1 year, 51% underwent at least one mammogram within 12 months of death.

Among women with a life expectancy of less than 5 years, 68% of women had received a mammogram 1 year after treatment; 53% underwent three mammograms within 3 years after treatment.

No funding for the study was declared. The investigators have disclosed no relevant financial relationships.

BOSTON – Older women who have had breast cancer frequently undergo annual surveillance mammography, even if there is only a small risk of their developing a second cancer or if they have other mortality risks associated with age and comorbidities. This ongoing annual surveillance with mammography may be doing more harm than good, warn researchers.

In a study that included almost 45,000 women who were aged 67 years or older when they were diagnosed with breast cancer, investigators found that patients commonly underwent annual mammographies.

“Even 10 years after their initial diagnosis ... about 40% of them were still getting surveillance mammography well into their 80s and 90s,” noted lead investigator Elizabeth Berger, MD, assistant professor of breast surgical oncology, Yale University, New Haven, Conn.

“Ongoing surveillance mammography in these patients may lead to overdiagnosis and overtreatment of cancers that potentially would not harm patients if left untreated,” Dr. Berger said.

“A positive or false positive finding may unnecessarily erode patient quality of life and incur costs to the patient and health care system without benefit,” she said. She added: “If an elderly woman is in poor health and has significant competing mortality risks compared to breast cancer, annual mammography may not be necessary.”
