Drug shortages in U.S. at 10-year high
Among the top five drug classes affected by shortages are chemotherapy drugs used in the treatment of cancer, many of which do not have alternatives.
“The shortage of certain cancer drugs has become a serious and life-threatening issue for cancer patients across the country,” Karen E. Knudsen, MBA, PhD, chief executive officer of the American Cancer Society (ACS) and its advocacy affiliate, the American Cancer Society Cancer Action Network (ACS CAN), said in a statement. “I have heard from patients and practitioners who are directly experiencing the impact of these shortages.”
As of early May, there were 15 oncology drugs on the official Food and Drug Administration drug shortage list. The other top drug classes on shortage include drugs used for central nervous system (CNS) disorders, antimicrobials, fluids and electrolytes, and hormones.
Factors blamed for the current shortages include expanded demand, supply shortages, limited manufacturing capacity, and low profit margins for generic therapies.
Dr. Knudsen emphasized that several of the oncology drugs now in short supply do not have an effective alternative. “As first-line treatments for a number of cancers, including triple-negative breast cancer, ovarian cancer, and leukemia often experienced by pediatric cancer patients, the shortage could lead to delays in treatment that could result in worse outcomes,” she said.
The ACS has listed the following oncology drugs and supportive agents as being in short supply: carboplatin injection used to treat triple negative breast cancer, ovarian, head, and neck cancers; fludarabine phosphate injection used for treating B-cell chronic lymphocytic leukemia; dacarbazine injection for treatment of skin cancer; amifostine injection; azacitidine injection; capecitabine tablets; cisplatin injection; cytarabine injection; dexamethasone sodium phosphate injection; hydrocortisone sodium succinate injection; leucovorin calcium lyophilized powder for injection; Lutetium Lu 177 vipivotide tetraxetan (Pluvicto) injection; methotrexate injection; pentostatin injection; and streptozocin (Zanosar) sterile powder.
Many of these drugs, such as cisplatin, are used in multiple regimens, so the issue is not limited to one specific cancer type.
In addition to these drugs, many products used in cancer care such as intravenous saline solutions are also in short supply, the ACS noted.
Two decades of shortages
Drug shortages in the United States have been a chronic problem for more than 2 decades, waxing and waning in intensity. In March, a hearing on drug shortages held by the Senate Committee on Homeland Security and Governmental Affairs noted that since 2001, the number of new drug shortages has ranged between 58 (in 2004) and 267 (in 2011). The trend toward new drug shortages declined from 2018 through 2021, but then rose to 160 in 2022.
The report further noted that the first quarter of 2023 marked the highest number of ongoing shortages by quarter since early 2018, with 301 active shortages as of March 31. For some drugs, the problem has become chronic, as more than 15 critical drug products have been in short supply for more than a decade, and 20 have been in shortage since at least 2015.
A 2022 survey of oncology pharmacists at 68 organizations nationwide showed that 63% of institutions reported one or more drug shortages every month, with a 34% increase in 2019, compared with 2018. Treatment delays, reduced doses, or alternative regimens were reported by 75% of respondents, the authors wrote.
Dr. Knudsen noted that the FDA is largely limited to working directly with the manufacturer on whatever issue is causing the shortage, as well as working with other manufacturers of the same product to urge them to ramp up production.
“ACS CAN is urging Congress to look at longer-term solutions that change the fundamental underpinnings of the shortages,” she said. “In the meantime, we urge the industry to work with medical practitioners to help identify alternatives where possible to ensure that cancer patients’ treatments are not delayed.”

Breast cancer survivors need a comprehensive care plan, says doctor
said Patricia A. Ganz, MD, during a presentation at the European Society for Medical Oncology Breast Cancer annual congress.
Several studies suggest that many breast cancer patients are not well prepared to move forward after a breast cancer diagnosis and subsequent treatments, continued Dr. Ganz, who works at the UCLA Jonsson Comprehensive Cancer Center, Los Angeles.
Meeting the survivorship needs of breast cancer patients requires addressing both their physical and psychosocial needs, Dr. Ganz said. She explained how to achieve that, but first pointed to research elaborating on what's missing from some breast cancer survivors' care and barriers to these patients having their variety of health-related needs met.
In a 2021 study published in the Journal of Cancer Survivorship, Dr. Ganz and colleagues conducted a survey of approximately 200 medical oncologists in the United States. They determined that less than 50% provide survivorship care plans to patients at the end of treatment or communicate with patients’ other physicians about follow-up care.
In a secondary analysis of data from the same survey published in 2022 in Breast Cancer Research and Treatment, Dr. Ganz and colleagues examined medical oncologists’ perceived barriers to addressing both physical and psychosocial long-term effects in breast cancer survivors. For both, lack of time was the greatest perceived barrier, cited by nearly two-thirds of oncologists. Other barriers to addressing physical effects included lack of evidence-based, effective interventions, lack of clinical algorithms to guide care, and ambiguity regarding professional responsibility at the end of treatment. Other top barriers to addressing psychosocial issues included lack of mental health providers, lack of psychosocial resources, and lack of clinician knowledge and skills.
Data from additional studies suggest that, overall, cancer patients with greater physical burdens, such as more complex and lengthy treatment regimens, also have greater psychosocial needs, Dr. Ganz noted. Plus, approximately 15%-20% of cancer survivors have ongoing anxiety and depressive symptoms.
Shift to primary care
As more breast cancer and other cancer patients survive for longer periods, more care will likely occur in general medical settings, Dr. Ganz said. Issues to be addressed will include the potential increased risk of comorbid conditions for these survivors, and whether survivorship interventions earlier in the disease trajectory will impact survivorship. For cancer patients who achieve remission after treatment, the first 5 years after a diagnosis involves treatment and short-term surveillance for late effects. Beyond 5 years, care for cancer survivors mainly involves primary care and management of any comorbid conditions, as well as surveillance for late effects and recurrences, and awareness of new research.
A patient consultation early in the process after diagnosis is the start of a continuum of care, Dr. Ganz said. A patient consultation should address symptoms related to initial treatments, such as neuropathy, pain, fatigue, and insomnia, as well as the psychological symptoms of anxiety and depression. An early consultation also should evaluate adherence to endocrine therapy and management of symptoms, if needed, with the larger goal of preparing patients for recovery and the transition to survivorship, and what to expect for long-term follow-up.
Delivering the three P’s
The “Three P’s” of survivor care for breast cancer patients are palliation, prevention, and promotion of health, according to Dr. Ganz .
The first “P,” for palliative, is a key part of survivorship care, said Dr. Ganz. Palliative care is defined as care that focuses on reducing symptom severity and improving quality of life. The biological effects of cancer treatment can be associated with physical effects, such as functional limitations and frailty, and behavioral/cognitive effects such as depression, fatigue, and cognitive deficits, she said. To manage these effects and provide palliative care, consultation is needed with specialists in relevant areas including mental health, pain management, physical medicine/rehabilitation, endocrinology, cardiology, and neurology.
The second “P,” which is for prevention in survivorship care, refers to ongoing follow-up screening to identify any potentially serious late-onset complications such as osteoporosis or cardiac disease so they can be addressed, said Dr. Ganz. Other considerations include chemoprevention if available and genetic counseling for patients with hereditary cancers. Prevention also includes counseling patients about lifestyle modifications to help prevent additional cancer.
The goal of the third “P,” which is for health promotion, is to promote risk reduction for the health problems associated with accelerated aging that may arise in cancer survivors, said Dr. Ganz.
Health promotion strategies include maintaining a healthy weight, increasing physical activity, and avoiding harmful exposures, she said. Healthy lifestyle interventions can also reduce the risk of other chronic diseases such as diabetes and heart disease.
To that end, Dr. Ganz outlined several behavioral interventions that may mitigate the effects of cancer treatment on the accelerated aging process, including stress reduction in the form of meditation or yoga, cognitive behavioral therapy, improving sleep, increasing physical activity, reducing obesity, and decreasing tobacco and alcohol use. These interventions may help reduce inflammation and promote tissue repair and healing.
For cancer survivors, the life span may be longer than the health span, and these patients may benefit from an integrated model of care, with systematic screening and consolidated appointments, rather than a fragmented model in which departments and referrals are siloed, which may result in conflicting advice or redundancy, said Dr. Ganz.
Looking ahead, more research is needed to explore models of care delivery, as requirements for survivor care will vary among patients and care settings, Dr. Ganz said.
However, regardless of setting, treatment plans and shared decision-making can help reduce potential long-term or late-emerging effects, she said. Developing a survivorship care plan can help patients learn how to enhance their recovery.
During a question and answer session, Dr. Ganz was asked about whether hormone therapy could be used for patients with hormone negative breast cancer. “I think vaginal estrogen can be used if someone is on tamoxifen,” she said. However, “we need to be cautious” in case there are remaining estrogen positive cells, in order to avoid potential metastases, and use of hormone therapy in breast cancer survivors is an individualized decision based in part on quality of life.
Engaging a patient’s partner early can be helpful
If possible, engage the patient’s partner in survivorship discussions, said Luzia Travado, PhD, head of psycho-oncology at the Champalimaud Foundation, Lisbon, who presented on the topic of sexuality and commented on survivorship during the discussion. For those women with partners, engaging the partner early in treatment often means they are more likely to play a larger role in the post treatment and long term by providing stability and emotional support.
“Make sure partners are engaged and understand that they have a role, and that this role is valued,” she said. Unfortunately, there are a lot of divorced women with breast cancer, as the disease can take a toll on relationships. However, remember “sexuality is not just sex; it is caring, loving, and intimacy.”
“To end on a positive note, it is important to empower patients, and to give them self-management skills so they can make things even better in their survivorship,” said Dr. Ganz. In spite of discussing difficulties and challenges, one of the goals of the session was to offer potential solutions and answers.
Dr. Ganz disclosed serving as editor of the cancer survivorship section on Up-to-Date, and serving as a consultant for Blue Note Therapeutics, GRAIL, InformedDNA, and Roche-Genentech. Dr. Travado had no relevant financial conflicts to disclose.

FROM ESMO BREAST CANCER 2023
Study explains link between fatty liver and CRC liver metastasis
according to the authors of new research.
These findings support the previously reported link between fatty liver and colorectal cancer (CRC) liver metastasis, and suggest that CRC patients with nonalcoholic fatty liver disease (NAFLD) may respond differently to treatment than CRC patients without NAFLD, wrote lead author Zhijun Wang, MD, PhD, of Cedars-Sinai Medical Center, Los Angeles, and colleagues, in their paper.
“Obesity and NAFLD are the significant risk factors for CRC,” the investigators explained, in Cell Metabolism. “A growing body of epidemiological evidence indicates that fatty liver increases the occurrence of CRC liver metastasis and the local recurrence after resection of CRC liver metastases, thereby worsening prognosis ... There is an urgent need to understand the molecular mechanisms of metastasis in patients with fatty liver to manage those patients effectively.”
To this end, Dr. Wang and colleagues conducted a series of experiments involving mice, cell cultures, and human sera. They found that fatty liver increases risk of CRC liver metastasis via extracellular vesicles (EVs) that contain procarcinogenic miRNAs. As these EVs transfer microRNAs from fatty liver hepatocytes to metastatic cancer cells, YAP activity increases, which, in turn, suppresses immune activity within the tumor microenvironment, promoting growth of CRC metastasis.
Beyond the increased risk of liver metastasis presented by fatty liver, the investigators suggested that NAFLD may cause “more complex” metastatic tumor microenvironments, potentially explaining “diverse responses” to cancer therapies among patients with CRC and liver metastases.
“In summary, our study demonstrates that the pre- and prometastatic liver environment of fatty liver is induced by procarcinogenic EVs and results in an immunosuppressive tumor microenvironemnt, in which YAP plays an important role,” the investigators concluded. “Our study provides new insight into [the] distinct liver tumor microenvironment in patients with fatty liver and without fatty liver, which may contribute to the aggressiveness of metastatic tumors and weak responses to anticancer therapy in patients with fatty liver. Additional studies are warranted to develop precision medicine for treating patients with CRC and liver metastasis.”

according to the authors of new research.
These findings support the previously reported link between fatty liver and colorectal cancer (CRC) liver metastasis, and suggest that CRC patients with nonalcoholic fatty liver disease (NAFLD) may respond differently to treatment than CRC patients without NAFLD, wrote lead author Zhijun Wang, MD, PhD, of Cedars-Sinai Medical Center, Los Angeles, and colleagues, in their paper.
“Obesity and NAFLD are the significant risk factors for CRC,” the investigators explained, in Cell Metabolism. “A growing body of epidemiological evidence indicates that fatty liver increases the occurrence of CRC liver metastasis and the local recurrence after resection of CRC liver metastases, thereby worsening prognosis ... There is an urgent need to understand the molecular mechanisms of metastasis in patients with fatty liver to manage those patients effectively.”
To this end, Dr. Wang and colleagues conducted a series of experiments involving mice, cell cultures, and human sera. They found that fatty liver increases risk of CRC liver metastasis via extracellular vesicles (EVs) that contain procarcinogenic miRNAs. As these EVs transfer microRNAs from fatty liver hepatocytes to metastatic cancer cells, YAP activity increases, which, in turn, suppresses immune activity within the tumor microenvironment, promoting growth of CRC metastasis.
Beyond the increased risk of liver metastasis presented by fatty liver, the investigators suggested that NAFLD may cause “more complex” metastatic tumor microenvironments, potentially explaining “diverse responses” to cancer therapies among patients with CRC and liver metastases.
“In summary, our study demonstrates that the pre- and prometastatic liver environment of fatty liver is induced by procarcinogenic EVs and results in an immunosuppressive tumor microenvironemnt, in which YAP plays an important role,” the investigators concluded. “Our study provides new insight into [the] distinct liver tumor microenvironment in patients with fatty liver and without fatty liver, which may contribute to the aggressiveness of metastatic tumors and weak responses to anticancer therapy in patients with fatty liver. Additional studies are warranted to develop precision medicine for treating patients with CRC and liver metastasis.”

Genomic assay changes minds on HER2+ BC treatment
The prospective pilot study is small, and the researchers didn’t report on how the patients fared, according to a poster presented at the European Society for Medical Oncology (ESMO) Breast Cancer annual congress. Plus, the test itself hasn’t been analyzed prospectively. But the study’s lead author, Olga Martínez-Sáez, MD, PhD, said in an interview that the 56% number is significant.
“We consider this percentage to be clinically very relevant,” said Dr. Martínez-Sáez, an oncologist at Hospital Clinic of Barcelona and the University of Barcelona. “HER2DX can change practice.”
Also in an interview, Kent Hoskins, MD, associate chief of hematology/oncology at University of Illinois at Chicago, described HER2DX as a next-generation genomic test that builds on assays developed 2 decades ago to help identify patients who would benefit – or not – from adjuvant chemotherapy.
Dr. Hoskins, who isn’t connected to the new study but has studied genomic tests for breast cancer, said the HER2DX test seeks to provide guidance to oncologists about which of several treatments are most effective in treating patients with HER2+ breast cancer.
“The overall trend in the HER2+ space is escalating therapy, and the cure rates have improved quite substantially,” he said. “But do they all need that much therapy? That’s the clinical question that this assay is addressing.”
The assay examines clinical features and the expression of 4 gene signatures, Dr. Martínez-Sáez said. It provides a risk score estimating the likelihood of recurrence plus a score that estimates the likelihood of achieving pathological complete response (pCR) with trastuzumab-based neoadjuvant therapy and an ERBB2 mRNA score.
In a retrospective 2022 study published in eBioMedicine, researchers reported that the assay “predicts response following neoadjuvant letrozole in combination with dual HER2 blockade with trastuzumab and pertuzumab in early-stage HER2-positive/hormone receptor–positive breast cancer.”
In the 2022 study, researchers wrote that assay results and other scores “might help better tailor systemic therapy in this context and identify candidates for avoiding chemotherapy, a therapy associated with short- and long-term toxicities and impact in quality of life.”
For the new study, a decision-impact analysis, researchers tracked 89 patients with HER2+ breast cancer (median age = 53 years, range 30-79, and 52% postmenopausal), the poster says. Most had T1-2 tumors (87%), negative nodes (64%), grade 2 (56%) or 3 (41%) tumors, and ductal histology (87%). And most were hormone receptor positive (65%). Seventy-eight percent of patients received neoadjuvant therapy (NAT), and 22% underwent upfront surgery.
In 56% of cases, oncologists changed their treatment decisions after getting the results of the HER2DX assays. In 59% of these cases, oncologists de-escalated therapy; in 41%, they escalated therapy, opting for more intense chemotherapy 65% of the time, according to the poster.
Clinician confidence in their decisions improved in 67% of cases, the researchers reported in their poster. Among 56 patients treated with neoadjuvant therapy who could be evaluated, “HER2DX pCR score was significantly associated with pCR (81% in pCR-medium/high and 32% in pCR-low; odds ratio=9.3, P = 0.001) independently of the rest of variables.”
Dr. Hoskins said the new report suggests that the assay can change treatment decisions, although he cautioned that “this study does not in itself establish its place in standard of care.” Large, prospective, randomized research is still needed, he said.
Dr. Martínez-Sáez said, in an interview, that the HER2DX assay should cost about as much as genomic assays for other breast cancer subtypes. These kinds of tests have cost several thousand dollars each in recent years.
What’s next? The decision impact study is ongoing. As for research into the assay itself, “prospective clinical trials are planned to demonstrate its clinical utility to de-escalate and guide therapy,” Dr. Martínez-Sáez said.
No funding is reported. Reveal Genomics is the developer of the HER2DX assay. Dr. Martinez- Saez reports financial relationships with Novartis, Eisai, Roche, and Reveal Genomics. Other study authors report multiple disclosures. Dr. Hoskins discloses non-financial research support from Agendia, which makes the MammaPrint early-breast-cancer assay.

T-DXd for HER2-low BC: Analysis confirms adverse effects
Interstitial lung disease (ILD) also remains a concern, and it’s not clear if retreatment after resolution is warranted.
In general, however, “T-DXd demonstrates a manageable safety profile consistent with prior reports. Results from this safety analysis continued to support its use as a new standard of care in patients with HER2-low metastatic breast cancer,” said report lead author Hope Rugo, MD, of the University of California, San Francisco, during a presentation at the European Society for Medical Oncology (ESMO) Breast Cancer annual congress.
T-DXd, an antibody-drug conjugate, received FDA approval in August 2022 for patients with HER2-low disease. The drug has been touted as “practice changing” and a “new standard of care.”
However, physicians have noted that the benefits of the drug come at the cost of significant adverse effects, including some that can cause hospitalization. There’s special concern about high-grade interstitial lung disease/pneumonitis, and an FDA boxed warning cautions clinicians about this possible side effect.
For the new analysis, researchers presented additional safety data from the industry-funded DESTINY-Breast04 trial, whose results was published in July 2022 in the New England Journal of Medicine. That study randomized 373 patients to T-DXd and 184 to physician’s choice of treatment. It found that, “among all patients, the median progression-free survival was 9.9 months in the trastuzumab deruxtecan group and 5.1 months in the physician’s choice group (hazard ratio for disease progression or death, 0.50; P < .001), and overall survival was 23.4 months and 16.8 months, respectively (hazard ratio for death, 0.64; P = .001).”
Exposure-adjusted incidence rates for any-grade treatment-emergent adverse events were lower for T-DXd versus physician’s choice of treatment (1.30 vs. 2.66). However, nausea and vomiting events were more than twice as common in patients who took T-DXd versus the physician’s choice (79.5% vs. 35.5%).
A total of 50.9% of patients in the T-DXd arm received antiemetic prophylaxis versus 37.2% in the physician’s choice arm. A single patient discontinued T-DXd treatment because of vomiting, and a single patient discontinued treatment because of nausea. No patients in the physician choice group discontinued treatment because of nausea or vomiting.
Neutropenia and febrile neutropenia were less frequent in the T-DXd arm versus physician’s choice (12.9% vs. 18.0% and 0.3% vs. 2.9%, respectively.)
ILD occurred in 45 patients (12.1%) of those in the T-DXd arm versus 1 (0.6%) in the physician choice arm. Ten patients of the patients in the T-DXd arm had not recovered by the data cutoff point.
Six patients with ILD were retreated following resolution; one discontinued because of an adverse event, two discontinued because of progressive disease, and three remained on the drug. “Given that there was only a small number of patients who were retreated with T-DXd, it’s difficult to make clinically meaningful conclusions on the effect of retreatment following grade IDL events that have resolved,” Dr. Rugo said.
In the big picture, “ILD pneumonitis remains an important identified risk and an adverse event of interest associated with T-DXd,” Dr. Rugo said. “It’s important that we adhere to management guidelines and updated toxicity management guidelines.”
In a discussion, Dr. Rugo said she prescribes three antiemetic drugs to help patients tolerate T-DXd therapy: “It makes a big difference. Anecdotally, it really has improved management of nausea. Start more and back down [as symptoms fade].”
Gustavo Werutsky, MD, PhD, of Moinhos de Vento Hospital, Porto Alegre, Brazil, the discussant for the presentation, also emphasized the importance of prevention and said he prescribes two or three prophylactic drugs. “In the beginning, we didn’t know these events were so important. A big part of the message is that patients from the beginning need to have a good prophylaxis for the nausea and vomiting.”
The researchers also presented a related report at the conference, an analysis of patient-reported outcomes from DESTINY-Breast02, a randomized phase 3 study of T-DXd (n = 406) versus physician’s choice of treatment (n = 202) in patients with HER2-positive metastatic breast cancer who were resistant/refractory to trastuzumab emtansine.
The analysis, led by Tanja Fehm, MD, of University Hospital Düsseldorf (Germany), found that the median time to definitive deterioration was longer with T-DXd versus the other arm per the EORTC QLQ-C30 global health status/quality of life score (14.1 vs. 5.9 months; HR, 0.56; 95% confidence interval, 0.44-0.71).

BMI has greater impact on survival in younger breast cancer patients
new data suggest.
Obesity is a well-known risk factor for breast cancer in postmenopausal women and has been associated with adverse prognosis, said Senna W.M. Lammers, MD, of Maastricht (the Netherlands) University during a presentation at the European Society for Medical Oncology (ESMO) Breast Cancer annual congress. In addition, some studies suggest that patients with higher body mass index (BMI) experience reduced benefits from endocrine therapy, she said.
Dr. Lammers and colleagues conducted a study to determine the prognostic and predictive effect of BMI on disease-free survival in postmenopausal women with hormone receptor–positive (HR+) breast cancer who were treated with extended endocrine therapy.
The study population included participants in the randomized, phase III DATA trial, which evaluated the use of 6 years vs. 3 years of anastrozole in postmenopausal women with HR+ breast cancer who were disease-free after 2-3 years of adjuvant tamoxifen therapy.
Patients were categorized based on BMI as having normal weight (18.5-24.9 kg/m2), overweight (25-29.9 kg/m2), or obese (30 kg/m2 or higher). The primary outcome was disease-free survival (DFS); the median follow-up period was 13.1 years.
DFS for patients with normal weight, overweight, and obesity was 66.2%, 59.5%, and 52.4%, with a P value of less than .001 for the trend, Dr. Lammers said. “These results were confirmed in multivariable analysis,” she said. Overall, patients with overweight and obesity had a worse DFS when compared with patients with normal weight (hazard ratio, 1.16; P = .10, for patients with overweight and HR, 1.26; P = .03 for patients with obesity).
“Next, we aimed to determine whether the prognostic effect of BMI differed by age,” Dr. Lammers said.
In women younger than 60 years, overweight and obesity were significantly associated with worse DFS (HR, 1.29; P = .05 and HR 1.83, P less than .001, respectively). However, this effect was not observed in women aged 60 years and older.
The researchers also examined the treatment effect of extended anastrozole on adapted DFS by weight, and found no significant differences among patients with normal weight, overweight, and obesity (HR, 1.00; HR, 0.74; and HR, 0.97, respectively), said Dr. Lammers.
In the question and answer session, Dr. Lammers was asked about possible explanations for the difference in DFS by age. Potential explanations include possible survival bias “as only the healthier [patients with obesity] survive to old age,” she said. Other potential explanations are biological, such as the potentially higher levels of bone density in older [patients with obesity], she said.
When asked about additional clinical implications, Dr. Lammers emphasized the importance of maintaining a healthy BMI for breast cancer patients of all ages. Other research areas might involve the use of lifestyle interventions, although these are challenging to implement, she noted.
Data draw attention to quality of life and lifestyle factors
The need to “look at drug development with new eyes” is particularly important when reviewing patient-reported outcomes, said Otto Metzger, MD, of the Dana Farber Cancer Institute, Boston, who served as the discussant for the session.
Dr. Metzger brought up the association between age and the effect of BMI on DFS, specifically.
Based on data from multiple studies and meta-analyses, “I do believe that obesity does play a role in prognosis,” he said, but the question is how long will researchers continue to simply record data without acting to add lifestyle interventions while also trying to develop new drugs, he said. Although convincing patients to make lifestyle changes remains a challenge, patients are often more motivated to make such changes after a cancer diagnosis, Dr. Metzger noted.
“I am a firm believer in the use of digital therapeutics in the context of clinical trials,” said Dr. Metzger. Digital technology offers great potential to educate patients on [adverse effects] and also to improve treatment adherence and quality of life, he concluded.
The study was supported by AstraZeneca, and Dr. Lammers disclosed financial relationships with AstraZeneca and Eli Lilly.

FROM ESMO BREAST CANCER 2023
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.
A coauthor reported personal fees from Astellas, AstraZeneca, AAA, Blue Earth, Janssen, Lantheus, Myovant, Myriad Genetics, Novartis, Telix, and Sanofi, as well as grants from Pfizer and Bayer during the conduct of the study. No other disclosures were reported.

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.

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.

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.

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.”

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.

“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.
