Number of cancer survivors with functional limitations doubled in 20 years
Vishal Patel, BS, a student at the Dell Medical School at The University of Texas at Austin, and colleagues identified 51,258 cancer survivors from the National Health Interview Survey, representing a weighted population of approximately 178.8 million from 1999 to 2018.
Most survivors were women (60.2%) and were at least 65 years old (55.4%). In 1999, 3.6 million weighted survivors reported functional limitation. In 2018, the number increased to 8.2 million, a 2.25-fold increase.
The number of survivors who reported no limitations also increased, but not by as much. That group grew 1.34-fold during the study period.
For context, “the 70% prevalence of functional limitation among survivors in 2018 is nearly twice that of the general population,” the authors wrote.
Patients surveyed on function
Functional limitation was defined as “self-reported difficulty performing any of 12 routine physical or social activities without assistance.” Examples of the activities included difficulty sitting for more than 2 hours, difficulty participating in social activities or difficulty pushing or pulling an object the size of a living room chair.
Over the 2 decades analyzed, the adjusted prevalence of functional limitation was highest among survivors of pancreatic cancer (80.3%) and lung cancer (76.5%). Prevalence was lowest for survivors of melanoma (62.2%), breast (61.8%) and prostate (59.5%) cancers.
Not just a result of living longer
Mr. Patel told this publication that one assumption people might make when they read these results is that people are just living longer with cancer and losing functional ability accordingly.
“But, in fact, we found that the youngest [– those less than 65 years–] actually contributed to this trend more than the oldest people, which means it’s not just [happening], because people are getting older,” he said.
Hispanic and Black individuals had disproportionately higher increases in functional limitation; percentage point increases over the 2 decades were 19.5 for Black people, 25.1 for Hispanic people and 12.5 for White people. There may be a couple of reasons for that, Mr. Patel noted.
Those who are Black or Hispanic tend to have less access to cancer survivorship care for reasons including insurance status and historic health care inequities, he noted.
“The other potential reason is that they have had less access to cancer care historically. And if, 20 years ago Black and Hispanic individuals didn’t have access to some chemotherapies, and now they do, maybe it’s the increased access to care that’s causing these functional limitations. Because chemotherapy can sometimes be very toxic. It may be sort of a catch-up toxicity,” he said.
Quality of life beyond survivorship
Mr. Patel said the results seem to call for building on improved survival rates by tracking and improving function.
“It’s good to celebrate that there are more survivors. But now that we can keep people alive longer, maybe we can shift gears to improving their quality of life,” he said.
The more-than-doubling of functional limitations over 2 decades “is a very sobering trend,” he noted, while pointing out that the functional limitations applied to 8 million people in the United States – people whose needs are not being met.
There’s no sign of the trend stopping, he continued. “We saw no downward trend, only an upward trend.”
Increasingly, including functionality as an endpoint in cancer trials, in addition to improvements in mortality, is one place to start, he added.
“Our findings suggest an urgent need for care teams to understand and address function, for researchers to evaluate function as a core outcome in trials, and for health systems and policy makers to reimagine survivorship care, recognizing the burden of cancer and its treatment on physical, psychosocial, and cognitive function,” the authors wrote in their paper. Limitations of the study include the potential for recall bias, lack of cancer staging or treatment information, and the subjective perception of function.

New USPSTF draft suggests mammography start at 40, not 50
The major change: USPSTF proposed reducing the recommended start age for routine screening mammograms from age 50 to age 40. The latest recommendation, which carries a B grade, also calls for screening every other year and sets a cutoff age of 74.
The task force’s A and B ratings indicate strong confidence in the evidence for benefit, meaning that clinicians should encourage their patients to get these services as appropriate.
The influential federal advisory panel last updated these recommendations in 2016. At the time, USPSTF recommended routine screening mammograms starting at age 50, and gave a C grade to starting before that.
In the 2016 recommendations, “we felt a woman could start screening in her 40s depending on how she feels about the harms and benefits in an individualized personal decision,” USPSTF member John Wong, MD, chief of clinical decision making and a primary care physician at Tufts Medical Center in Boston, said in an interview. “In this draft recommendation, we now recommend that all women get screened starting at age 40.”
Two major factors prompted the change, explained Dr. Wong. One is that more women are being diagnosed with breast cancer in their 40s. The other is that a growing body of evidence showing that Black women get breast cancer younger, are more likely to die of breast cancer, and would benefit from earlier screening.
“It is now clear that screening every other year starting at age 40 has the potential to save about 20% more lives among all women and there is even greater potential benefit for Black women, who are much more likely to die from breast cancer,” Dr. Wong said.
The American Cancer Society (ACS) called the draft recommendations a “significant positive change,” while noting that the task force recommendations only apply to women at average risk for breast cancer.
The American College of Radiology (ACR) already recommends yearly mammograms for average risk women starting at age 40. Its latest guidelines on mammography call for women at higher-than-average risk for breast cancer to undergo a risk assessment by age 25 to determine if screening before age 40 is needed.
When asked about the differing views, Debra Monticciolo, MD, division chief for breast imaging at Massachusetts General Hospital, said annual screenings that follow ACR recommendations would save more lives than the every-other-year approach backed by the task force. Dr. Monticciolo also highlighted that the available scientific evidence supports earlier assessment as well as augmented and earlier-than-age-40 screening of many women – particularly Black women.
“These evidence-based updates should spur more-informed doctor–patient conversations and help providers save more lives,” Dr. Monticciolo said in a press release.
Insurance access
Typically, upgrading a USPSTF recommendation from C to B leads to better access and insurance coverage for patients. The Affordable Care Act (ACA) of 2010 requires insurers to cover the cost of services that get A and B recommendations from the USPSTF without charging copays – a mandate intended to promote greater use for highly regarded services.
But Congress created a special workaround that effectively makes the ACA mandate apply to the 2002 task force recommendations on mammography. In those recommendations, the task force gave a B grade to screening mammograms every 1 or 2 years starting at age 40 without an age limit.
Federal lawmakers have sought to provide copay-free access to mammograms for this entire population even when the USPSTF recommendations in 2009 and 2016 gave a C grade to routine screening for women under 50.
Still, “it is important to note that our recommendation is based solely on the science of what works to prevent breast cancer and it is not a recommendation for or against insurance coverage,” the task force acknowledged when unveiling the new draft update. “Coverage decisions involve considerations beyond the evidence about clinical benefit, and in the end, these decisions are the responsibility of payors, regulators, and legislators.”
Uncertainties persist
The new draft recommendations also highlight the persistent gaps in knowledge about the uses of mammography, despite years of widespread use of this screening tool.
The updated draft recommendations emphasize the lack of sufficient evidence to address major areas of concern related to screening and treating Black women, older women, women with dense breasts, and those with ductal carcinoma in situ (DCIS).
The task force called for more research addressing the underlying causes of elevated breast cancer mortality rates among Black women.
The USPSTF also issued an ‘I’ statement for providing women with dense breasts additional screening with breast ultrasound or MRI and for screening women older than 75 for breast cancer. Such statements indicate that the available evidence is lacking, poor quality, or conflicting, and thus the USPSTF can’t assess the benefits and harms or make a recommendation for or against providing the preventive service.
“Nearly half of all women have dense breasts, which increases their risk for breast cancer and means that mammograms may not work as well for them. We need to know more about whether and how additional screening might help women with dense breasts stay healthy,” the task force explained.
The task force also called for more research on approaches to reduce the risk for overdiagnosis and overtreatment for breast lesions, such as DCIS, which are identified through screening.
One analysis – the COMET study – is currently underway to assess whether women could be spared surgery for DCIS and opt for watchful waiting instead.
“If we can find that monitoring them carefully, either with or without some sort of endocrine therapy, is just as effective in keeping patients free of invasive cancer as surgery, then I think we could help to de-escalate treatment for this very low-risk group of patients,” Shelley Hwang, MD, MPH, principal investigator of the COMET study, told this news organization in December.
The task force will accept comments from the public on this draft update through June 5.

Familial cancer risk complex, not limited to same site
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.

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.

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.

Pausing endocrine therapy to attempt pregnancy is safe
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.

Preop MRI does not reduce positive margins in breast surgery
BOSTON – 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.

Mammography after breast cancer: No benefit for older patients?
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.
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.

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.
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.

SCC from breast implants: Negligible risk, study finds
Findings from a large cohort study suggest the incidence of SCC is negligible. The analysis found one case of SCC among nearly 57,000 women who had undergone breast implant reconstruction over 421,227 person-years of follow-up.
The authors also confirmed the known risk of breast implant–associated anaplastic large-cell lymphoma (ALCL), identifying five cases in the population, which was considered a “significantly elevated” risk.
Although patients with breast cancer who are eligible for mastectomy should be counseled on the risks for cancer after implant reconstruction, patients “should not be dissuaded from pursuing implant-based reconstruction because of the risk of SCC,” lead author Connor J. Kinslow, MD, of Columbia University, New York, and colleagues concluded.
SCC cases associated with breast implants are distinct from breast implant–associated ALCL, the authors noted, explaining that this lymphoma “is the subject of a boxed warning on all saline- and silicone gel–filled breast implants since 2020.”
The results were published in a research letter in JAMA Surgery.
Last September, a safety communication from the FDA highlighted reports of SCC and other lymphomas associated with breast implants. The FDA said it was aware of fewer than 20 cases of SCC.
Following the safety communication, Dr. Kinslow and colleagues assessed SCC risk among 56,785 women who underwent cancer-directed mastectomy with implant reconstruction for breast tumors.
Women in the cohort were diagnosed between 2000 and 2018 and included in the Surveillance, Epidemiology, and End Results (SEER) 17 database. Patients had a median age of 51 years; most (84%) where White, 8.1% were Black, 7.4% were Asian or Pacific Islander, 0.4% were American Indian/Alaska Native, and race was unknown in 0.4%.
Across 421,227 person-years of follow-up, the team identified one case of SCC, corresponding to an incidence rate of 2.37 per million person-years vs. an expected incidence of 1.02 per million person-years in the general population. Although the 2.33 standardized incidence ratio (SIR) “appeared elevated vs. the general population,” it was “not significant given the low incidence” (95% confidence interval, 0.06-13.0).
The team also identified five cases of breast implant–associated ALCL. That corresponded to an incidence rate of 11.9 per million person-years compared with an expected incidence of 0.29 per million person-years – for a significantly elevated SIR of 40.9. The authors also noted more than 1,000 reported cases of breast implant–associated ALCL previous as well as a robust association with implants.
Regarding SCC, “whether the observed elevated risk is associated with the implants is difficult to interpret because it is based on only one case and wide [confidence intervals],” the authors said. But, overall, “we found that the incidence rate of SCC was extraordinarily low and of minimal public health concern.”

Intraoperative pathology spurs overtreatment in mastectomy
(AxRT), warned U.S. investigators.
The team studied data on more than 40,000 clinically node-negative women who underwent upfront mastectomy. Just over 8,000 patients were found to have one to two SLN, with intraoperative pathology performed in approximately one-third.
Intraoperative pathology was associated with a more than eightfold increase in the likelihood of performing both ALND and AxRT, far more than any other factor.
These results provide “evidence that a significant percentage of the mastectomy patients with limited disease in up to two SLNs may be overtreated. … simply because their pathology results are read and acted on while they are on the operating table,” said senior author Olga Kantor, MD, MS, associate program director, Breast Surgical Oncology Fellowship Program, Brigham and Women’s Hospital and Dana-Farber Cancer Institute, Boston.
“Notably, postsurgical decisions typically involve a multidisciplinary team, including radiation oncologists, which will likely result in a more integrated overall treatment plan,” she commented in a statement.
“This study suggests that surgeons should delay ALND decision-making until a later time to avoid overtreating patients,” Dr. Kantor emphasized.
The research was presented at the annual meeting of the American Society of Breast Surgeons, and was highlighted in a premeeting press briefing.
Approached for comment on the new findings, Sarah L. Blair, MD, professor and vice chair, department of surgery, University of California San Diego Health, noted that “there is a great deal of data on deescalation in axillary surgery in patients undergoing breast conservation with radiation.”
Dr. Blair, who was not involved in the study, noted that, while there are some studies in mastectomy patients with equal oncologic results, “the topic remains more controversial.”
“This study highlights that surgeons strongly consider deescalating axillary surgery in mastectomy patients to reduce long-term complications,” she said in an interview.
“If possible, these patients should be discussed in a multidisciplinary fashion ahead of time,” she emphasized.
“If surgeons send the lymph nodes for frozen section then, as this paper demonstrates, they will act on the information and perform axillary dissection for early-stage disease.”
Study details
At the press briefing for the study, Dr. Kantor explained that several clinical trials, including AMAROS, have already “established the safety of axillary observation or AxRT as an alternative to ALND” in clinically node-negative breast cancer patients found to have one to two positive SLN.
She noted that “mastectomy patients were included in these trials, but they made up a minority” of the populations, ranging from 9% to 18%, “and so controversy remains over the optimal axillary management” in this patient population.
Dr. Kantor said that intraoperative pathology assessment “can help avoid the need to return to the operating room for additional axillary surgery” by checking the SLN at the time.
However, acting on the results during the procedure “does not allow for multidisciplinary discussion” and can mean that patients end up having both ALND and postoperative AxRT.
“This dual approach may result in axillary overtreatment in patients who may otherwise have been eligible for axillary radiation alone,” she underlined.
Moreover, a recent survey of 680 surgeons by the ASBrS found that 52% were performing routine intraoperative pathology assessment of SLN, and 78% of those said they would perform ALND if the results came back positive.
To investigate the impact of intraoperative pathology assessment on axillary management in mastectomy patients who would have been eligible for the AMAROS trial, the team examined data from the U.S. National Cancer Database.
They included cT1-2N0 breast cancer patients who had upfront mastectomy in 2018-2019 and were found to have one to two positive SLN.
They defined intraoperative pathology assessment as:
- “Not done/not acted on” if ALND was either not performed or performed at a later date than the pathology assessment.
- “Done/acted on” if both ALND and the pathology assessment were carried out on the same day.
In addition, AxRT was defined as postmastectomy radiation to the chest wall that included radiation to the draining lymph nodes.
The researchers identified 40,467 patients, of whom 20.3% had one to two positive SLN. Among those, axillary management consisted of observation in 33.2%, ALND in 26.6%, AxRT in 22.2%, and ALND plus AxRT in 18.0%.
Overall, 37.2% of the patients underwent intraoperative pathology and 62.8% did not, 11.8% of whom later returned to the operating room for ALND.
Patients who underwent intraoperative pathology were more likely than those who did not to have cT2 disease (48.0% vs. 44.1%), lympho-vascular invasion (43.4% vs. 37.1%), two positive SLN (26.5% vs. 19.2%), and macrometastasis (87.6% vs. 64.2%, P < .001 for all).
Rates of ALND plus AxRT were significantly higher in patients who had intraoperative pathology done/acted on than in those whom intraoperative pathology was not done/not acted on, at 41.0% vs. 4.9% (P < .001).
Adjusted multivariate analysis indicated that receipt of ALND plus AxRT was significantly associated with intraoperative pathology being done/acted on vs. being not done/acted on, at an odds ratio of 8.99 (P < .001).
There were also significant associations between having both procedures and macrometastasis in the SLN, at an odds ratio vs. micrometastasis of 3.38 (P < .001), and the number of total positive SLN, at odds ratio vs. 1 of 2.14 for two nodes, 3.92 for three nodes, and 5.32 for > three nodes (P < .001 for all).
The researchers also found that lobular tumors on histologic analysis were associated with having ALND plus AxRT, at an odds ratio vs. ductal histology of 1.40 (P < .001).
No funding was declared. Dr. Kantor and Dr. Blair report no relevant financial relationships.

- “Done/acted on” if both ALND and the pathology assessment were carried out on the same day.
In addition, AxRT was defined as postmastectomy radiation to the chest wall that included radiation to the draining lymph nodes.
The researchers identified 40,467 patients, of whom 20.3% had one to two positive SLN. Among those, axillary management consisted of observation in 33.2%, ALND in 26.6%, AxRT in 22.2%, and ALND plus AxRT in 18.0%.
Overall, 37.2% of the patients underwent intraoperative pathology and 62.8% did not, 11.8% of whom later returned to the operating room for ALND.
Patients who underwent intraoperative pathology were more likely than those who did not to have cT2 disease (48.0% vs. 44.1%), lympho-vascular invasion (43.4% vs. 37.1%), two positive SLN (26.5% vs. 19.2%), and macrometastasis (87.6% vs. 64.2%, P < .001 for all).
Rates of ALND plus AxRT were significantly higher in patients who had intraoperative pathology done/acted on than in those whom intraoperative pathology was not done/not acted on, at 41.0% vs. 4.9% (P < .001).
Adjusted multivariate analysis indicated that receipt of ALND plus AxRT was significantly associated with intraoperative pathology being done/acted on vs. being not done/acted on, at an odds ratio of 8.99 (P < .001).
There were also significant associations between having both procedures and macrometastasis in the SLN, at an odds ratio vs. micrometastasis of 3.38 (P < .001), and the number of total positive SLN, at odds ratio vs. 1 of 2.14 for two nodes, 3.92 for three nodes, and 5.32 for > three nodes (P < .001 for all).
The researchers also found that lobular tumors on histologic analysis were associated with having ALND plus AxRT, at an odds ratio vs. ductal histology of 1.40 (P < .001).

(AxRT), warned U.S. investigators.
The team studied data on more than 40,000 clinically node-negative women who underwent upfront mastectomy. Just over 8,000 patients were found to have one to two SLN, with intraoperative pathology performed in approximately one-third.
Intraoperative pathology was associated with a more than eightfold increase in the likelihood of performing both ALND and AxRT, far more than any other factor.
These results provide “evidence that a significant percentage of the mastectomy patients with limited disease in up to two SLNs may be overtreated. … simply because their pathology results are read and acted on while they are on the operating table,” said senior author Olga Kantor, MD, MS, associate program director, Breast Surgical Oncology Fellowship Program, Brigham and Women’s Hospital and Dana-Farber Cancer Institute, Boston.
“Notably, postsurgical decisions typically involve a multidisciplinary team, including radiation oncologists, which will likely result in a more integrated overall treatment plan,” she commented in a statement.
“This study suggests that surgeons should delay ALND decision-making until a later time to avoid overtreating patients,” Dr. Kantor emphasized.
The research was presented at the annual meeting of the American Society of Breast Surgeons, and was highlighted in a premeeting press briefing.
Approached for comment on the new findings, Sarah L. Blair, MD, professor and vice chair, department of surgery, University of California San Diego Health, noted that “there is a great deal of data on deescalation in axillary surgery in patients undergoing breast conservation with radiation.”
Dr. Blair, who was not involved in the study, noted that, while there are some studies in mastectomy patients with equal oncologic results, “the topic remains more controversial.”
“This study highlights that surgeons strongly consider deescalating axillary surgery in mastectomy patients to reduce long-term complications,” she said in an interview.
“If possible, these patients should be discussed in a multidisciplinary fashion ahead of time,” she emphasized.
“If surgeons send the lymph nodes for frozen section then, as this paper demonstrates, they will act on the information and perform axillary dissection for early-stage disease.”
Study details
At the press briefing for the study, Dr. Kantor explained that several clinical trials, including AMAROS, have already “established the safety of axillary observation or AxRT as an alternative to ALND” in clinically node-negative breast cancer patients found to have one to two positive SLN.
She noted that “mastectomy patients were included in these trials, but they made up a minority” of the populations, ranging from 9% to 18%, “and so controversy remains over the optimal axillary management” in this patient population.
Dr. Kantor said that intraoperative pathology assessment “can help avoid the need to return to the operating room for additional axillary surgery” by checking the SLN at the time.
However, acting on the results during the procedure “does not allow for multidisciplinary discussion” and can mean that patients end up having both ALND and postoperative AxRT.
“This dual approach may result in axillary overtreatment in patients who may otherwise have been eligible for axillary radiation alone,” she underlined.
Moreover, a recent survey of 680 surgeons by the ASBrS found that 52% were performing routine intraoperative pathology assessment of SLN, and 78% of those said they would perform ALND if the results came back positive.
To investigate the impact of intraoperative pathology assessment on axillary management in mastectomy patients who would have been eligible for the AMAROS trial, the team examined data from the U.S. National Cancer Database.
They included cT1-2N0 breast cancer patients who had upfront mastectomy in 2018-2019 and were found to have one to two positive SLN.
They defined intraoperative pathology assessment as:
- “Not done/not acted on” if ALND was either not performed or performed at a later date than the pathology assessment.
- “Done/acted on” if both ALND and the pathology assessment were carried out on the same day.
In addition, AxRT was defined as postmastectomy radiation to the chest wall that included radiation to the draining lymph nodes.
The researchers identified 40,467 patients, of whom 20.3% had one to two positive SLN. Among those, axillary management consisted of observation in 33.2%, ALND in 26.6%, AxRT in 22.2%, and ALND plus AxRT in 18.0%.
Overall, 37.2% of the patients underwent intraoperative pathology and 62.8% did not, 11.8% of whom later returned to the operating room for ALND.

Novel fluorescence guidance improves lumpectomy outcomes
, new phase 3 findings show.
Pegulicianine (Lumisight), an investigational and activatable fluorescent imaging agent used with a novel direct visualization system, helped identify residual tumor or circumvent second surgeries in about 10% of patients in the trial.
Use of the agent and direct visualization system – both from Lumicell and currently under review by the Food and Drug Administration – could provide more complete resection for patients with early breast cancer and avert the need for reexcisions, the investigators write.
The findings were published online in NEJM Evidence and were subsequently presented at the annual meeting of the American Society of Breast Surgeons.
Local recurrence following lumpectomy increases the risk of dying from breast cancer, and the risk of local recurrence is directly linked to inadequate tumor removal during lumpectomy. In about 20%-40% of lumpectomies, positive margins are identified after surgery.
To improve patient outcomes, investigators assessed whether a novel fluorescence-guided surgery system helped surgeons perform more complete resections during lumpectomy.
In the Novel Surgical Imaging for Tumor Excision (INSITE) trial, 392 patients were randomly assigned to undergo pegulicianine fluorescence-guided surgery (n = 357) or standard lumpectomy (n = 35).
To prevent surgeons from performing a smaller than standard lumpectomy in anticipation of using the pegulicianine fluorescence-guided system, patients were randomly assigned to the pegulicianine fluorescence-guided surgery group or the control group. The groups were revealed only after the surgeon completed the standard lumpectomy.
“Randomization was not designed to provide a control group for analysis of device performance,” The authors explain. “In this study design, each patient undergoing pegulicianine fluorescence-guided surgery served as her own control,” they write. The investigators compared final margin pathology after standard lumpectomy and after guided surgery. Those in the control group were included in the safety analysis.
Study participants were women aged 18 years or older who were undergoing lumpectomy for stage I–III breast cancer and/or ductal carcinoma in situ. All patients received pegulicianine 1.0 mg/kg via a 3-minute intravenous infusion 2-6 hours before surgery.
The agent produces a signal at sites of residual tumor, and a handheld probe illuminates the cavity during surgery. A tumor detection algorithm then analyzes and displays the images to the surgeon in real time – an overall process that adds about 7 minutes to the operative procedure, the authors say.
Investigators identified invasive cancers in 316 patients and in situ cancers in 76 patients. Among the 357 patients in the treatment group, 27 (7.6%) were found to have residual tumor after standard lumpectomy. For 22 patients, cavity orientations were deemed negative on standard margin evaluations, the authors report.
With use of pegulicianine fluorescence-guided surgery, positive margins were converted to negative margins for 9 of 62 patients (14.5%), potentially averting a second surgery in those patients.
Overall, the authors say that pegulicianine fluorescence-guided surgery removed residual tumor (27 of 357) or avoided second surgeries (9 of 357) in 10% of patients in the trial.
The current trial findings confirm results regarding the safety and efficacy of pegulicianine fluorescence-guided surgery and the direct visualization system that were reported in a prior multicenter feasibility study, the authors say.
Pegulicianine fluorescence-guided surgery met prespecified thresholds for removal of residual tumor and specificity, at 85.2%, but did not meet the prespecified threshold for sensitivity, which was only 49.3%.
The rate of serious adverse events with pegulicianine was 0.5% (two patients), similar to that of other contrast agents. Administration of the agent was stopped because of adverse events for six patients, the investigators write.
Serious adverse events included grade 3 hypersensitivity in one patient and an anaphylactic reaction in another. The other four adverse events included an allergic reaction, milder hypersensitivity, nausea, and pegulicianine extravasation. All adverse events resolved, and patients proceeded to standard lumpectomy.
Overall, the trial findings “suggest that a more complete breast cancer resection may be achieved” with pegulicianine fluorescence-guided surgery and the direct visualization system, lead investigator Barbara Smith, MD, PhD, director of the breast program at Massachusetts General Hospital and professor of surgery at Harvard Medical School, both in Boston, said in a press release. “Given the low complication rate, minimal added operative time and, most importantly, the discovery of additional cancer left behind after a lumpectomy, the Lumicell [system] has the potential to be a critical adjunct to enhance standard practice for breast cancer patients.”
The system also has the potential to reduce “the patient burden of additional surgery” and decrease “costs associated with a return to the operating room,” the authors conclude.
The INSITE trial was funded by Lumicell and the National Institutes of Health. Dr. Smith reported unpaid research collaboration with Lumicell.

FROM NEJM EVIDENCE
Study shows higher obesity-related cancer mortality in areas with more fast food
based on data from a new cross-sectional study of more than 3,000 communities.
Although increased healthy eating has been associated with reduced risk of obesity and with reduced cancer incidence and mortality, access to healthier eating remains a challenge in communities with less access to grocery stores and healthy food options (food deserts) and/or easy access to convenience stores and fast food (food swamps), Malcolm Seth Bevel, PhD, of the Medical College of Georgia, Augusta, and colleagues, wrote in their paper, published in JAMA Oncology.
In addition, data on the association between food deserts and swamps and obesity-related cancer mortality are limited, they said.
“We felt that the study was important given the fact that obesity is an epidemic in the United States, and multiple factors contribute to obesity, especially adverse food environments,” Dr. Bevel said in an interview. “Also, I lived in these areas my whole life, and saw how it affected underserved populations. There was a story that needed to be told, so we’re telling it,” he said in an interview.
In a study, the researchers analyzed food access and cancer mortality data from 3,038 counties across the United States. The food access data came from the U.S. Department of Agriculture Food Environment Atlas (FEA) for the years 2012, 2014, 2015, 2017, and 2020. Data on obesity-related cancer mortality came from the Centers for Disease Control and Prevention for the years from 2010 to 2020.
Food desert scores were calculated through data from the FEA, and food swamp scores were based on the ratio of fast-food restaurants and convenience stores to grocery stores and farmers markets in a modification of the Retail Food Environment Index score.
The researchers used an age-adjusted, multiple regression model to determine the association between food desert and food swamp scores and obesity-related cancer mortality rates. Higher food swamp and food desert scores (defined as 20.0 to 58.0 or higher) were used to classify counties as having fewer healthy food resources. The primary outcome was obesity-related cancer mortality, defined as high or low (71.8 or higher per 100,000 individuals and less than 71.8 per 100,000 individuals, respectively).
Overall, high rates of obesity-related cancer mortality were 77% more likely in the counties that met the criteria for high food swamp scores (adjusted odds ratio 1.77). In addition, researchers found a positive dose-response relationship among three levels of both food desert scores and food swamp scores and obesity-related cancer mortality.
A total of 758 counties had obesity-related cancer mortality rates in the highest quartile. Compared to counties with low rates of obesity-related cancer mortality, counties with high rates of obesity-related cancer mortality also had a higher percentage of non-Hispanic Black residents (3.26% vs. 1.77%), higher percentage of adults older than 65 years (15.71% vs. 15.40%), higher rates of adult obesity (33.0% vs. 32.10%), and higher rates of adult diabetes (12.50% vs. 10.70%).
Possible explanations for the results include the lack of interest in grocery stores in neighborhoods with a population with a lower socioeconomic status, which can create a food desert, the researchers wrote in their discussion. “Coupled with the increasing growth rate of fast-food restaurants in recent years and the intentional advertisement of unhealthy foods in urban neighborhoods with [people of lower income], the food desert may transform into a food swamp,” they said.
The findings were limited by several factors including the study design, which did not allow for showing a causal association of food deserts and food swamps with obesity-related cancer mortality, the researchers noted. Other limitations included the use of groups rather than individuals, the potential misclassification of food stores, and the use of county-level data on race, ethnicity, and income, they wrote.
The results indicate that “food swamps appear to be a growing epidemic across the U.S., likely because of systemic issues, and should draw concern and conversation from local and state officials,” the researchers concluded.
Community-level investments can benefit individual health
Dr. Bevel said he was not surprised by the findings, as he has seen firsthand the lack of healthy food options and growth of unhealthy food options, especially for certain populations in certain communities. “Typically, these are people who have lower socioeconomic status, primarily non-Hispanic Black or African American or Hispanic American,” he said “I have watched people have to choose between getting fruits/vegetables versus their medications or running to fast food places to feed their families. What is truly surprising is that we’re not talking about people’s lived environment enough for my taste,” he said.
“I hope that our data and results can inform local and state policymakers to truly invest in all communities, such as funding for community gardens, and realize that adverse food environments, including the barriers in navigating these environments, have significant consequences on real people,” said Dr. Bevel. “Also, I hope that the results can help clinicians realize that a patient’s lived environment can truly affect their obesity and/or obesity-related cancer status; being cognizant of that is the first step in holistic, comprehensive care,” he said.
“One role that oncologists might be able to play in improving patients’ access to healthier food is to create and/or implement healthy lifestyle programs with gardening components to combat the poorest food environments that their patients likely reside in,” said Dr. Bevel. Clinicians also could consider the innovative approach of “food prescriptions” to help reduce the effects of deprived, built environments, he noted.
Looking ahead, next steps for research include determining the severity of association between food swamps and obesity-related cancer by varying factors such as cancer type, and examining any potential racial disparities between people living in these environments and obesity-related cancer, Dr. Bevel added.
Data provide foundation for multilevel interventions
The current study findings “raise a clarion call to elevate the discussion on food availability and access to ensure an equitable emphasis on both the importance of lifestyle factors and the upstream structural, economic, and environmental contexts that shape these behaviors at the individual level,” Karriem S. Watson, DHSc, MS, MPH, of the National Institutes of Health, Bethesda, Md., and Angela Odoms-Young, PhD, of Cornell University, Ithaca, N.Y., wrote in an accompanying editorial.
The findings provide a foundation for studies of obesity-related cancer outcomes that take the community environment into consideration, they added.
The causes of both obesity and cancer are complex, and the study findings suggest that the links between unhealthy food environments and obesity-related cancer may go beyond dietary consumption alone and extend to social and psychological factors, the editorialists noted.
“Whether dealing with the lack of access to healthy foods or an overabundance of unhealthy food, there is a critical need to develop additional research that explores the associations between obesity-related cancer mortality and food inequities,” they concluded.
The study received no outside funding. The researchers and the editorialists had no financial conflicts to disclose.

“I hope that our data and results can inform local and state policymakers to truly invest in all communities, such as funding for community gardens, and realize that adverse food environments, including the barriers in navigating these environments, have significant consequences on real people,” said Dr. Bevel. “Also, I hope that the results can help clinicians realize that a patient’s lived environment can truly affect their obesity and/or obesity-related cancer status; being cognizant of that is the first step in holistic, comprehensive care,” he said.
“One role that oncologists might be able to play in improving patients’ access to healthier food is to create and/or implement healthy lifestyle programs with gardening components to combat the poorest food environments that their patients likely reside in,” said Dr. Bevel. Clinicians also could consider the innovative approach of “food prescriptions” to help reduce the effects of deprived, built environments, he noted.
Looking ahead, next steps for research include determining the severity of association between food swamps and obesity-related cancer by varying factors such as cancer type, and examining any potential racial disparities between people living in these environments and obesity-related cancer, Dr. Bevel added.
Data provide foundation for multilevel interventions
The current study findings “raise a clarion call to elevate the discussion on food availability and access to ensure an equitable emphasis on both the importance of lifestyle factors and the upstream structural, economic, and environmental contexts that shape these behaviors at the individual level,” Karriem S. Watson, DHSc, MS, MPH, of the National Institutes of Health, Bethesda, Md., and Angela Odoms-Young, PhD, of Cornell University, Ithaca, N.Y., wrote in an accompanying editorial.
The findings provide a foundation for studies of obesity-related cancer outcomes that take the community environment into consideration, they added.
The causes of both obesity and cancer are complex, and the study findings suggest that the links between unhealthy food environments and obesity-related cancer may go beyond dietary consumption alone and extend to social and psychological factors, the editorialists noted.
“Whether dealing with the lack of access to healthy foods or an overabundance of unhealthy food, there is a critical need to develop additional research that explores the associations between obesity-related cancer mortality and food inequities,” they concluded.
The study received no outside funding. The researchers and the editorialists had no financial conflicts to disclose.
based on data from a new cross-sectional study of more than 3,000 communities.
Although increased healthy eating has been associated with reduced risk of obesity and with reduced cancer incidence and mortality, access to healthier eating remains a challenge in communities with less access to grocery stores and healthy food options (food deserts) and/or easy access to convenience stores and fast food (food swamps), Malcolm Seth Bevel, PhD, of the Medical College of Georgia, Augusta, and colleagues, wrote in their paper, published in JAMA Oncology.
In addition, data on the association between food deserts and swamps and obesity-related cancer mortality are limited, they said.
“We felt that the study was important given the fact that obesity is an epidemic in the United States, and multiple factors contribute to obesity, especially adverse food environments,” Dr. Bevel said in an interview. “Also, I lived in these areas my whole life, and saw how it affected underserved populations. There was a story that needed to be told, so we’re telling it,” he said in an interview.
In a study, the researchers analyzed food access and cancer mortality data from 3,038 counties across the United States. The food access data came from the U.S. Department of Agriculture Food Environment Atlas (FEA) for the years 2012, 2014, 2015, 2017, and 2020. Data on obesity-related cancer mortality came from the Centers for Disease Control and Prevention for the years from 2010 to 2020.
Food desert scores were calculated through data from the FEA, and food swamp scores were based on the ratio of fast-food restaurants and convenience stores to grocery stores and farmers markets in a modification of the Retail Food Environment Index score.
The researchers used an age-adjusted, multiple regression model to determine the association between food desert and food swamp scores and obesity-related cancer mortality rates. Higher food swamp and food desert scores (defined as 20.0 to 58.0 or higher) were used to classify counties as having fewer healthy food resources. The primary outcome was obesity-related cancer mortality, defined as high or low (71.8 or higher per 100,000 individuals and less than 71.8 per 100,000 individuals, respectively).
Overall, high rates of obesity-related cancer mortality were 77% more likely in the counties that met the criteria for high food swamp scores (adjusted odds ratio 1.77). In addition, researchers found a positive dose-response relationship among three levels of both food desert scores and food swamp scores and obesity-related cancer mortality.
A total of 758 counties had obesity-related cancer mortality rates in the highest quartile. Compared to counties with low rates of obesity-related cancer mortality, counties with high rates of obesity-related cancer mortality also had a higher percentage of non-Hispanic Black residents (3.26% vs. 1.77%), higher percentage of adults older than 65 years (15.71% vs. 15.40%), higher rates of adult obesity (33.0% vs. 32.10%), and higher rates of adult diabetes (12.50% vs. 10.70%).
Possible explanations for the results include the lack of interest in grocery stores in neighborhoods with a population with a lower socioeconomic status, which can create a food desert, the researchers wrote in their discussion. “Coupled with the increasing growth rate of fast-food restaurants in recent years and the intentional advertisement of unhealthy foods in urban neighborhoods with [people of lower income], the food desert may transform into a food swamp,” they said.
The findings were limited by several factors including the study design, which did not allow for showing a causal association of food deserts and food swamps with obesity-related cancer mortality, the researchers noted. Other limitations included the use of groups rather than individuals, the potential misclassification of food stores, and the use of county-level data on race, ethnicity, and income, they wrote.
The results indicate that “food swamps appear to be a growing epidemic across the U.S., likely because of systemic issues, and should draw concern and conversation from local and state officials,” the researchers concluded.
Community-level investments can benefit individual health
Dr. Bevel said he was not surprised by the findings, as he has seen firsthand the lack of healthy food options and growth of unhealthy food options, especially for certain populations in certain communities. “Typically, these are people who have lower socioeconomic status, primarily non-Hispanic Black or African American or Hispanic American,” he said “I have watched people have to choose between getting fruits/vegetables versus their medications or running to fast food places to feed their families.
