Breast cancer exacts high financial toll worldwide
but in low- and middle-income countries as well, a meta-analysis found.
Although the rate of financial toxicity was much higher in low- and middle-income countries – affecting 79% of patients – more than 35% of patients in high-income countries also incurred financial hardship, the study team found.
The findings highlight the need for policies to offset the burden of direct and indirect costs for breast cancer care and improve the financial health of vulnerable patients, said the study authors, led by Kavitha Ranganathan, MD, of Brigham and Women’s Hospital and Harvard Medical School, Boston.
The study was published online in JAMA Network Open.
The most expensive malignancy?
Patients with breast cancer may be particularly burdened by costs of care, with one study showing substantially higher out-of-pocket costs for patients with breast cancer than colorectal, lung, and prostate cancer combined.
A Lancet Oncology Commission report revealed that breast cancer was the most expensive cancer in the United States in 2010, accounting for $16.5 billion, or 13% of all cancer-related spending. A separate analysis found that individual direct medical costs of breast cancer care can reach $100,000.
In high-income countries, the financial burden of breast cancer care may be the result of novel and costly cancer therapeutics and interventions, overuse of services, increased willingness to pay, and varying insurance coverage. In low- and middle-income countries, women may experience delayed diagnosis because of limited access to screening and high-quality diagnostic services, leading to more later-stage diagnoses requiring more extensive treatments. Lower baseline income, limited insurance coverage, and greater distance to treatment centers may also be factors.
“Establishing the global extent of financial toxicity and comparing the economic burden of disease in different populations is imperative to help policy makers prioritize funding of breast cancer care infrastructure,” Dr. Ranganathan and colleagues write.
In their meta-analysis of 18 studies – 14 from high-income countries and 4 from low – published from 2008 to 2021, the authors found that the definition of financial toxicity varied widely across studies.
For example, some used specific numerical criteria for defining financial toxicity, such as medical cost exceeding 40% of household capacity to pay or potential income or out-of-pocket costs exceeding 30% of annual household income.
Others used patient-reported outcome measures instruments evaluating subjective statements of financial difficulty, such as an affirmative answer to having financial difficulty or trouble paying medical bills, or paying more for medical care than is affordable.
In other studies, financial toxicity was defined according to a patient’s report of specific, objective financial consequences of care, including losing income or a job; having to borrow money or go into debt; having trouble paying for food, rent, or transportation; or having to forgo any type of medical care because of cost.
In their analysis, the pooled rate of financial toxicity among patients with breast cancer was 35.3% in high-income countries and 78.8% in low/middle-income countries, both demonstrating high heterogeneity or variability (P for heterogeneity < .001). In contrast, typical financial toxicity rates across all health conditions in low-income countries ranged from 6% to 12%, the investigators noted.
One study assessing quality of life measures in Egypt found that 47.5% of patients were food insecure, 66% needed financial assistance, 34% used savings to pay for treatment, and 41.2% lacked savings altogether.
Burden reduction
Given the high rates of financial toxicity associated with breast cancer, what strategies might reduce this cost burden?
When exploring potential factors associated with financial toxicity, the researchers found no clear association between financial toxicity and race, employment status, and age, and could draw no firm conclusions about the impact of comorbidities and urban vs. rural place of residence. In addition, cancer stage and treatments were “extremely” heterogeneous across studies and the authors found no clear association between either factor and financial toxicity.
But the authors noted that the highest-priority patients are typically those who have low education, have low socioeconomic status, lack health insurance, and live in low-resource areas.
To reduce financial toxicity and improve outcomes among patients with breast cancer, the study team recommended four potential strategies:
- Use targeted educational campaigns to raise awareness about the signs and symptoms of breast cancer and the importance of early diagnosis and treatment.
- Expand health care coverage to minimize direct medical out-of-pocket costs.
- Develop programs to assist with direct nonmedical and indirect costs, such as transportation to and lodging near treatment centers and childcare.
- Improve screening, referral, and treatment infrastructure for breast cancer care.
The researchers also noted that their data highlight the value of universal health care coverage as a policy strategy, with evidence of lower financial toxicity rates in countries with universal health coverage.
Support for the study was provided in part by the National Cancer Institute, United Nations Institute for Training and Research and the Global Surgery Foundation, Harvard Global Health Institute, Connors Center for Women’s Health and Gender Biology, the Center for Surgery and Public Health, and the National Endowment for Plastic Surgery. Dr. Ranganathan reports no relevant financial relationships. Several coauthors have disclosures; the full list can be found with the original article.

Genomic clues to poor outcomes in young breast cancer patients
and offer clues about molecular targets for future trials.
Compared with older women with early stage HR-positive breast cancer, women under 40 years of age had significantly higher frequencies of certain mutations, such as GATA3, as well as genomic features associated with a poor prognosis. Notably, the researchers found that women with such poor prognostic features vs. those with none had a significantly worse 8-year distant recurrence-free interval and overall survival.
“We have demonstrated age-related differences in genomic profiles with enrichment of genomic features associated with poor prognosis in these younger premenopausal women compared with older premenopausal and postmenopausal women,” the authors wrote in the study, published in the Annals of Oncology. Importantly, the genomic features highlight “the potential for age-focused treatment strategies.”
Charis Eng, MD, PhD, of the Cleveland Clinic Genomic Medicine Institute, Ohio, noted that the findings are promising but need further validation.
“With time and the appropriate clinical trials in place, I envision that these findings will enable the personalized genomics-driven management of these cancers – not only treatment, but also toward prevention,” said Dr. Eng, who was not involved in the study.
Young premenopausal women, particularly those with HR-positive, luminal breast cancer, are known to have significantly higher recurrence rates and worse survival, compared with older women, but the reasons have remained unclear.
Although previous studies have identified key gene expression signatures linked to worse outcomes in younger patients with breast cancer, there are limited data on this younger patient population, especially by breast cancer subtype. Given that breast cancer treatment strategies are often similar across age groups, such evidence gaps could represent missed opportunities for developing more targeted treatment strategies for this high-risk population of young women.
To further investigate the cancer-specific genetic profiles in younger women, Sherene Loi, MD, PhD, of the Peter MacCallum Cancer Centre, University of Melbourne, and colleagues turned to data from the pivotal, multicenter Suppression of Ovarian Function Trial (SOFT).
Using next-generation sequencing, Dr. Loi and colleagues evaluated HR-positive, HER2-negative tumors among a subset of 1,276 premenopausal women who were diagnosed with early stage breast cancer. The study employed deep-targeted sequencing for most patients (n = 1,258) as well as whole-exome sequencing in a matched case-control subsample of young women with a median age of 38 years (n = 82).
Compared with women aged 40 and older, those under 40 years of age (n = 359) had significantly higher frequencies of mutations in GATA3 (19% vs. 16%) and copy number-amplifications (47% vs. 26%).
Younger women also had significantly higher features suggestive of homologous recombination deficiency (27% vs. 21% in older women), and a higher proportion of PIK3CA mutations with concurrent copy number-amplifications (23% vs. 11%, respectively), all considered to be poor prognostic features.
In addition, younger women had significantly lower frequencies of certain mutations, including PIK3CA (32% vs. 47%), CDH1 (3% vs. 9%), and MAP3K1 (7% vs. 12%), compared with older women.
Overall, 46% of women had poor prognostic features. These poor prognostic features were observed in 72% of patients under age 35, compared with 54% aged 35-39, and 40% of those 40 and over.
Compared with women without those features, women with poor prognostic features had a lower 8-year distant recurrence-free interval of 84% vs. 94% (hazard ratio, 1.85), and worse 8-year overall survival of 88% vs. 96%, respectively (HR, 2.20). Notably, younger women under age 40 had the poorest outcomes, with an 8-year distant recurrence-free interval rate of 74% vs. 85% in older women, and an 8-year overall survival of 80% vs. 93%, respectively.
How might these results inform potential therapeutics?
Drugs targeting the homologous recombination deficiency pathway are well established, and up to 36% of very young patients in the study showed genomic features of homologous recombination deficiency, the authors noted.
In addition, Dr. Eng explained, there are other Food and Drug Administration–approved treatments that can target the copy number amplified, PIK3CA-mutated tumors, including therapies that target PIK3CA itself, or proteins downstream of it. However, use of such therapies would need “to be tested experimentally, especially since pathway inhibition sometimes may result in rebound signaling to promote tumor growth,” Dr. Eng said.
An important caveat is that patients with germline BRCA1 or BRCA2 mutations may be underrepresented in the SOFT clinical trial, as the trial excluded patients who already had bilateral oophorectomy or planned to within 5 years, the authors noted.
Nevertheless, Dr. Loi said that the study is important because “there are no other datasets as large or with this long follow-up for very young women with breast cancer.”
Furthermore, “the SOFT clinical trial was practice-changing, so using the tumor samples associated with this study is more impactful than smaller cohorts with no outcome data or institutional retrospective cohorts,” she said.
Dr. Eng agreed that the study’s size is an important attribute, allowing the authors to “identify differences that would have been missed in a smaller and more heterogeneous series.”
She added that future research should also include ancestry and racial diversity.
“While young women have higher occurrences of aggressive breast cancers, mortality is twice as likely in young Black women, compared to young White women,” Dr. Eng said.
The study received funding from a Susan G. Komen for the Cure Promise Grant, the National Health and Research Council of Australia, the Breast Cancer Research Foundation, and the National Breast Cancer Foundation of Australia, and support from the family of Judy Eisman in Australia. Dr. Loi and Dr. Eng report no relevant financial disclosures.

‘Valid option’ for partial breast irradiation in breast cancer
The study covered in this summary was published on researchsquare.com as a preprint and has not yet been peer reviewed.
Key takeaway
Why this matters
- According to numerous guidelines, partial breast irradiation after lumpectomy is a sound approach for early-stage breast cancer, but there is a lack of consensus about treatment schedules.
- The investigators suggest that 30 Gy in five daily fractions is a “valid option” for these patients in a field that lacks consensus.
Study design
- The team reviewed 381 women with early breast cancer treated with this approach (30 Gy in five daily fractions) at their center from 2013 to 2022.
- Half of patients had left-sided tumors, 94.5% had invasive ductal carcinomas, 96.6% had grade 1 or grade 2 disease, and tumors were luminal like in 99.2% of patients.
- Following lumpectomy, women underwent partial breast irradiation to the tumor bed plus 15 mm of isometric expansion beyond it.
- Follow-up was a median of 28 months.
Key results
- Seven patients (2%) had a local recurrence, of which two were in the treatment field.
- Three-year local control, disease-free survival, and overall survival were high (97.5%, 95.7%, and 96.9%, respectively).
- Nearly 90% of patients and 97% of physicians reported good or excellent cosmesis.
- Ten patients (2.9%) had grade 2 late toxicities, including edema, asthenia, and fibrosis; there were no grade 3 or higher adverse events.
- Five patients (1.5%) had late cardiac major events, four of whom were treated on the right breast; three patients (0.9%) had late pulmonary fibrosis.
- The safety and efficacy outcomes are in line with previous reports, including those that used different dosage and/or fractionation schedules.
Limitations
- The study was retrospective, with a relatively short follow-up.
- Quality of life was not assessed.
- There was no objective baseline measure of cosmesis against which to compare cosmetic results.

Key takeaway
Why this matters
- According to numerous guidelines, partial breast irradiation after lumpectomy is a sound approach for early-stage breast cancer, but there is a lack of consensus about treatment schedules.
- The investigators suggest that 30 Gy in five daily fractions is a “valid option” for these patients in a field that lacks consensus.
Study design
- The team reviewed 381 women with early breast cancer treated with this approach (30 Gy in five daily fractions) at their center from 2013 to 2022.
- Half of patients had left-sided tumors, 94.5% had invasive ductal carcinomas, 96.6% had grade 1 or grade 2 disease, and tumors were luminal like in 99.2% of patients.
- Following lumpectomy, women underwent partial breast irradiation to the tumor bed plus 15 mm of isometric expansion beyond it.
- Follow-up was a median of 28 months.
Key results
- Seven patients (2%) had a local recurrence, of which two were in the treatment field.
- Three-year local control, disease-free survival, and overall survival were high (97.5%, 95.7%, and 96.9%, respectively).
- Nearly 90% of patients and 97% of physicians reported good or excellent cosmesis.
- Ten patients (2.9%) had grade 2 late toxicities, including edema, asthenia, and fibrosis; there were no grade 3 or higher adverse events.
- Five patients (1.5%) had late cardiac major events, four of whom were treated on the right breast; three patients (0.9%) had late pulmonary fibrosis.
- The safety and efficacy outcomes are in line with previous reports, including those that used different dosage and/or fractionation schedules.
Limitations
- The study was retrospective, with a relatively short follow-up.
- Quality of life was not assessed.
- There was no objective baseline measure of cosmesis against which to compare cosmetic results.

Radiotherapy for early breast cancer: Sharp cutoff at age 70
say researchers reporting new data showing a sharp cut-off at age 70.
“In our study, one of the most significant variables in determining whether breast cancer patients who are close their 70th birthday are recommended standard-of-care radiation or de-escalated treatment is whether they show up a few months before or a few months after that 70th birthday,” commented study author Wesley J. Talcott, MD, of the department of therapeutic radiology at the Yale School of Medicine, New Haven, Conn.
The results show a trend in which radiation therapy is 50% less likely to be prescribed for patients age 70 and older with early-stage breast cancer, even when controlling for population size, patient demographics, and disease specific variables.
This suggests that oncologists are weighing the variable of age too heavily when deciding on adjuvant treatments, the authors suggest.
“In certain circumstances, breast cancer oncology providers are treating age like a binary categorical variable when selecting patients for treatments or diagnostic procedures, rather than the continuous variable that it is,” Dr. Talcott commented.
The study was published online in the International Journal of Radiation Oncology: Biology, Physics.
Approached for comment, Casey Chollet-Lipscomb, MD, radiation oncologist with Tennessee Oncology, Nashville, who was not associated with the study, agreed with its main finding.
“The study helps emphasize the importance of individualized care,” she said. “Increasing age is the most common risk factor for breast cancer, but breast cancer is an incredibly diverse disease. While you can observe trends based on age, every patient is unique, and they can’t be lumped into one bucket and prescribed treatment based on a strict age cutoff.”
The retrospective study included two cohorts of women identified in the National Cancer Data Base (2004-2017) all of whom underwent lumpectomy for early-stage breast cancer. All patients had “strong indications” for adjuvant treatment.
Patients in cohort 1 (n = 160,990) included women with estrogen-receptor negative cancer, tumor size greater than 3 cm, who were determined to be “appropriate” for radiation therapy.
Patients in cohort 2 (n = 394,946) had hormone-receptor positive cancer, tumor size greater than 5 mm, and were considered to be “appropriate” candidates for endocrine therapy.
Multivariable analysis was performed to control for comorbidity burden (measured by the Charlson-Deyo Comorbidity Index), race and ethnicity, insurance status, academic versus non-academic treatment center, median annual income of a patient’s area of residence, distance from the site of treatment, and pathology variables including number of lymph nodes sampled, histologic grade, and genomic risk score.
In cohort 1, radiation was recommended for 90%-92% of patients between the ages of 50-69; this dropped to 81% for those aged 70.
After MVA, it was determined that age difference was an independent predictor for adjuvant radiation recommendation only at age 70 versus 69 (odds ratio, 0.47; 95% confidence interval 0.39-0.57, P < .001).
For cohort 2, year-over-year age difference predicted endocrine therapy recommendation only at the juncture between age 70 versus 69 (OR, 0.86, 95% CI 0.74-0.99, P = .001).
“Our results don’t say that we should be increasing the amount of treatment for patients over the age [of] 70 or decreasing that patient treatment for patients younger than age 70. What we believe is that we need to be assessing physiologic age of our patients when treating patients,” Dr. Talcott said.
“We would do this by looking at not just how many years a patient has been on this Earth but also what their current health status is, how many good quality-of-life years they might have after treatment or without it, and what the patient wants in terms of burden of treatment. This is a much more valuable way to approach the allocation of treatments than using age alone,” he added.
Both Dr. Talcott and Dr. Chollet-Lipscomb agreed that a limitation of the study was a lack of data on how physicians decided on a specific treatment in each individual case, but they agree that even without this information the results were “significant.”
Dr. Chollet-Lipscomb also highlighted the factors other than age she would use to determine the best adjuvant treatment for a patient with early stage breast cancer, including the individual features of the tumor, how aggressive it looks under the microscope, what the receptor status is, and a patient’s overall performance status and comorbidities.
Dr. Talcott and Dr. Chollet-Lipscomb report no relevant financial relationships. The authors had no acknowledgement of research support for this study.

Use of diagnostic mammograms is inconsistent, survey finds
Existing guidelines offer little help, according to Pavani Chalasani, MD, MPH, who presented the study at the San Antonio Breast Cancer Symposium. “They just say [do an] annual mammogram, but they don’t say, ‘Do we need to do screening? Do we need to do breast MRIs?’”
Her personal experience also reflected a general confusion. “I asked my colleagues and got different answers from seven colleagues,” said Dr. Chalasani, who is an oncologist at the University of Arizona Cancer Center, Tucson.
She noted that diagnostic mammograms are generally similar to screening mammograms, but the radiologist is viewing the images in real time and can take additional views as needed while the patient is still present. “That is the biggest difference,” said Dr. Chalasani. No studies have been conducted to determine which method produces better results.
To get a snapshot of current practice, she and her colleagues developed a survey, which the American Society of Clinical Oncology sent to 1,000 randomly selected members between Oct. 19 and Nov. 22, 2021. 244 individuals responded; 93.5% were physicians, and half identified as female. A total of 174 respondents were medical oncologists, 31 were radiation oncologists, and 20 were surgical oncologists. The imbalance among respondents is a limitation of the study. That “may or may not be reflective of our real-time practices (among surgeons), but we do think that since a lot of times patients are seen by medical oncologists, there could be overlap,” said Dr. Chalasani.
About 50% of respondents said that they use breast MRI in the diagnosis of 25% or fewer patients. Approximately 64% of respondents said they used diagnostic mammograms versus about 31% who used imaging mammograms at first imaging. About 53% said they ordered mammograms within the first 6 months after treatment.
38% of those who ordered diagnostic mammograms for surveillance used it for 3-5 years, while 29% continued it for 5 years or more. One-quarter employed additional imaging during follow-up, most commonly breast ultrasound. About 65% said they had no stop date for screening mammograms, as long as the patient remained healthy. The choice of screening or diagnostic mammography was about 50:50, though about 55% said they use screening mammography for patients 80 years of age or older.
Dr. Chalasani pointed out that both screening and diagnostic mammograms provide similar imaging quality. Screening mammograms are completely covered by insurance, while diagnostic mammograms typically require a copay. “We’re doing this [diagnostic mammography] with no guidelines, but there is this out of pocket cost, without knowing if it’s the right thing to do,” she said.
National Comprehensive Cancer Network guidelines indicate that diagnostic mammograms can be conducted for 5 years after a ductal carcinoma in situ diagnosis, but it doesn’t provide guidance for invasive cancers. Some past studies suggested that doing diagnostic mammograms for 3 years may increase diagnosis, but it isn’t clear if any such advantage would actually result in a clinical difference, according to Dr. Chalasani. “With the treatments we have, we still might cure [the cancer]. So what endpoints are we looking for? Are we changing care to add on toxicity to the patient, and stress to the patient and also for the health care system?”
She hopes that physicians will look at the results and understand that diagnostic mammograms, while they intuitively feel superior, are not supported by guidelines, and patients must incur an extra cost.
Her team also plans to conduct cost-effectiveness analysis of diagnostic mammograms.
Dr. Chalasani has no relevant financial disclosures.

FDA OKs sacituzumab govitecan for HR+ metastatic breast cancer
for patients with unresectable, locally advanced or metastatic hormone receptor (HR)–positive, HER2-negative breast cancer after endocrine-based therapy and at least two additional systemic therapies for metastatic disease.
Label expansion for the Trop-2–directed antibody-drug conjugate was based on the TROPICS-02 trial, which randomized 543 adults 1:1 to either sacituzumab govitecan 10 mg/kg IV on days 1 and 8 of a 21-day cycle or single agent chemotherapy, most often eribulin but also vinorelbine, gemcitabine, or capecitabine.
Median progression free survival was 5.5 months with sacituzumab govitecan versus 4 months with single agent chemotherapy (hazard ratio, 0.66; P = .0003). Median overall survival was 14.4 months in the sacituzumab govitecan group versus 11.2 months with chemotherapy (HR, 0.79), according to an FDA press release announcing the approval.
In a Gilead press release, Hope Rugo, MD, a breast cancer specialist at the University of California, San Francisco, and principal investigator for TROPICS-02, said the approval “is significant for the breast cancer community. We have had limited options to offer patients after endocrine-based therapy and chemotherapy, and to see a clinically meaningful survival benefit of more than 3 months with a quality-of-life benefit for these women is exceptional.”
The most common adverse events associated with sacituzumab govitecan in the trial, occurring in a quarter or more of participants, were decreased leukocyte count, decreased neutrophil count, decreased hemoglobin, decreased lymphocyte count, diarrhea, fatigue, nausea, alopecia, glucose elevation, constipation, and decreased albumin.
Labeling for the agent carries a boxedwarning of severe or life-threatening neutropenia and severe diarrhea.
The recommended dose is the trial dose: 10 mg/kg IV on days 1 and 8 of 21-day cycles until disease progression or unacceptable toxicity.
Sacituzumab govitecan was previously approved for unresectable, locally advanced or metastatic triple-negative breast cancer after two or more prior systemic therapies and locally advanced or metastatic urothelial cancer after platinum-based chemotherapy and either a PD-1 or PD-L1 inhibitor.

for patients with unresectable, locally advanced or metastatic hormone receptor (HR)–positive, HER2-negative breast cancer after endocrine-based therapy and at least two additional systemic therapies for metastatic disease.
Label expansion for the Trop-2–directed antibody-drug conjugate was based on the TROPICS-02 trial, which randomized 543 adults 1:1 to either sacituzumab govitecan 10 mg/kg IV on days 1 and 8 of a 21-day cycle or single agent chemotherapy, most often eribulin but also vinorelbine, gemcitabine, or capecitabine.
Median progression free survival was 5.5 months with sacituzumab govitecan versus 4 months with single agent chemotherapy (hazard ratio, 0.66; P = .0003). Median overall survival was 14.4 months in the sacituzumab govitecan group versus 11.2 months with chemotherapy (HR, 0.79), according to an FDA press release announcing the approval.
In a Gilead press release, Hope Rugo, MD, a breast cancer specialist at the University of California, San Francisco, and principal investigator for TROPICS-02, said the approval “is significant for the breast cancer community. We have had limited options to offer patients after endocrine-based therapy and chemotherapy, and to see a clinically meaningful survival benefit of more than 3 months with a quality-of-life benefit for these women is exceptional.”
The most common adverse events associated with sacituzumab govitecan in the trial, occurring in a quarter or more of participants, were decreased leukocyte count, decreased neutrophil count, decreased hemoglobin, decreased lymphocyte count, diarrhea, fatigue, nausea, alopecia, glucose elevation, constipation, and decreased albumin.

Race and geography tied to breast cancer care delays
suggesting the need to target high-risk geographic regions and patient groups to ensure timely care, new research suggests.
Among nearly 33,000 women from North Carolina with stage I-III breast cancer, Black patients were nearly twice as likely has non-Black patients to experience treatment delays of more than 60 days, researchers found.
“Our findings suggest that treatment delays are alarmingly common in patients at high risk for breast cancer death, including young Black women and patients with stage III disease,” the authors note in their article, which was published online in Cancer.
Research shows that breast cancer treatment delays of 30-60 days can lower survival, and Black patients face a “disproportionate risk of treatment delays across the breast cancer care delivery spectrum,” the authors explain.
However, studies exploring whether or how racial disparities in treatment delays relate to geography are more limited.
In the current analysis, researchers amassed a retrospective cohort of all patients with stage I-III breast cancer between 2004 and 2015 in the North Carolina Central Cancer Registry and explored the risk of treatment delay by race and geographic subregion.
The cohort included 32,626 women, 6,190 (19.0%) of whom were Black. Counties were divided into the nine Area Health Education Center regions for North Carolina.
Compared with non‐Black patients, Black patients were more likely to have stage III disease (15.2% vs. 9.3%), hormone receptor–negative tumors (29.3% vs. 15.6%), Medicaid insurance (46.7% vs. 14.9%), and to live within 5 miles of their treatment site (30.6% vs. 25.2%).
Overall, Black patients were almost two times more likely to experience a treatment delay of more than 60 days (15% vs. 8%).
On average, about one in seven Black women experienced a lengthy delay, but the risk varied depending on geographic location. Patients living in certain regions of the state were more likely to experience delays; those in the highest-risk region were about twice as likely to experience a delay as those in the lowest-risk region (relative risk, 2.1 among Black patients; and RR, 1.9 among non-Black patients).
The magnitude of the racial gap in treatment delay varied by region – from 0% to 9.4%. But overall, of patients who experienced treatment delays, a significantly greater proportion were Black patients in every region except region 2, where only 2.7% (93 of 3,362) of patients were Black.
Notably, two regions with the greatest disparities in treatment delay, as well as the highest absolute risk of treatment delay for Black patients, surround large cities.
“These delays weren’t explained by the patients’ distance from cancer treatment facilities, their specific stage of cancer or type of treatment, or what insurance they had,” lead author Katherine Reeder-Hayes, MD, with the University of North Carolina Lineberger Comprehensive Cancer Center, Chapel Hill, said in a news release.
Instead, Dr. Reeder-Hayes said, the findings suggest that the structure of local health care systems, rather than patient characteristics, may better explain why some patients experience treatment delays.
In other words, “if cancer care teams in certain areas say, ‘Oh, it’s particularly hard to treat breast cancer in our area because people are poor or have really advanced stages of cancer when they come in,’ our research does not bear out that explanation,” Dr. Reeder-Hayes said in email to this news organization.
This study “highlights the persistent disparities in treatment delays Black women encounter, which often lead to worse outcomes,” said Kathie-Ann Joseph, MD, MPH, who was not involved in the research.
“Interestingly, the authors could not attribute these delays in treatment to patient-level factors,” said Dr. Joseph, a breast cancer surgeon at NYU Langone Perlmutter Cancer Center, New York. But the authors “did find substantial geographic variation, which suggests the need to address structural barriers contributing to treatment delays in Black women.”
Sara P. Cate, MD, who was not involved with the research, also noted that the study highlights a known issue – “that racial minorities have longer delays in cancer treatment.” And notably, she said, the findings reveal that this disparity persists in areas where access to care is better and more robust.
“The nuances of the delays to care are multifactorial,” said Dr. Cate, a breast cancer surgeon and director of the Breast Surgery Quality Program at Mount Sinai in New York. “We need to do better with this population, and it is a multilevel solution of financial assistance, social work, and patient navigation.”
The study was supported in part by grants from the Susan G. Komen Foundation and the NC State Employees’ Credit Union. Dr. Reeder-Hayes, Dr. Cate, and Dr. Joseph have disclosed no relevant financial relationships.

Quality of life predicts chemo tolerance in early breast cancer
a new analysis found.
Baseline quality-of-life measures, most often fatigue and physical functioning, have “been associated with survival in various cancers,” the authors explain. These latest findings signal that assessing fatigue and physical functioning prior to treatment “could help to identify patients who are at risk for poor chemotherapy tolerability.”
The findings were published online in the journal Cancer.
Although quality of life is recognized as a predictor of survival in patients with advanced cancer, the evidence is less clear in early-stage breast cancer.
To understand the role quality-of-life measures play in early breast cancer, the investigators performed an ancillary analysis of the French Cancer and Toxicities (CANTO) study, which enrolled women with newly diagnosed stage I-III invasive breast cancer at 26 centers in France.
The ancillary CANTO‐PRED study was designed to explore the association between baseline quality of life measures and chemotherapy dose reductions and postchemotherapy toxicities among 3,079 patients with early breast cancer. This included 718 patients who received chemotherapy in the neoadjuvant setting and 2,361 who received chemotherapy as adjuvant treatment.
Most patients received taxanes (94.2%) and/or anthracyclines (90.5%). Other major adjuvant treatments were breast radiation therapy (92.6%), trastuzumab (21%), and endocrine therapy (74%), and all women underwent either breast-conserving surgery (74%) and/or lymph node dissection (60%). Fatigue and physical functioning were measured using the European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire Core 30.
Among the 3,079 patients, 15.5% experienced chemotherapy dose reductions and 31% developed postchemotherapy toxicities.
After multivariable adjustment for clinical and patient factors, those with baseline fatigue scores greater than 39 (vs. 39 or less) had higher odds of chemotherapy dose reductions (odds ratio, 1.43) and postchemotherapy toxicities (OR, 1.32). Those with baseline physical functioning scores less than 83 (vs. 83 or higher) also had higher odds of chemotherapy dose reductions (OR, 1.54) and postchemotherapy toxicities (OR, 1.50), the authors found.
In addition, cognitive functioning, pain, sleep disturbances, and appetite loss dimensions were associated with both chemotherapy dose reductions and postchemotherapy toxicities, whereas nausea, vomiting, and dyspnea were associated with postchemotherapy toxicities.
The researchers also found that performance status was not associated with chemotherapy dose reductions or postchemotherapy toxicities, suggesting patient-reported quality of life may be a better predictor of outcomes, the authors said.
“The ability to predict important toxicities with baseline information could lead to improvements in the prevention and management of adverse treatment effects by targeting a group of patients who may need [dose reductions] or may have residual toxicities,” the authors concluded.
This study was funded by the French National Research Agency. The authors reported various relevant financial relationships.

FDA OKs elacestrant for ESR1+ advanced, metastatic breast cancer
that progressed on at least one line of endocrine therapy.
The agency also approved the Guardant360 CDx assay as a companion diagnostic to identify breast cancer patients who meet the treatment requirements, according to the agency’s press release announcing the approval.
The novel oral selective estrogen receptor degrader was approved based on the phase 3 EMERALD trial, which included 478 postmenopausal women and men with ER-positive, HER2-negative advanced or metastatic breast cancer, about half of whom had ESR1 mutations. Patients had progressed on one or two prior lines of endocrine therapy, including one containing a CDK4/6 inhibitor. Participants could also have had one prior line of chemotherapy in the advanced or metastatic setting.
Participants were randomized 1:1 to either elacestrant 345 mg orally once daily or investigator’s choice of endocrine therapy, which included fulvestrant or an aromatase inhibitor.
In the 228 patients (48%) with ESR1 mutations, median progression-free survival (PFS) was 3.8 months with elacestrant versus 1.9 months in the fulvestrant or aromatase inhibitor arm (hazard ratio, 0.55; P = .0005). Investigators observed no statistically significant PFS difference between the treatment arms in patients who didn’t have the mutation.
Fair comparison?
In June, experts raised concerns about the adequacy of the “standard of care” control arm in EMERALD, particularly that single agents were used at a time when combination therapy is becoming more common.
“The expression ‘standard of care’ is applied generously, as the control arm is restricted” to single agents and no combinations, which “may have led to a substandard” comparison group, Timothée Olivier, MD, Geneva University Hospital, and Vinay Prasad, MD, MPH, University of California, San Francisco, said in an editorial quoted in the piece.
EMERALD investigators acknowledged that there were issues with the control group, noting that in the “United States and Europe, combination therapy with fulvestrant” – instead of single agents – “is increasingly being used as the second-line [standard of care] treatment.”
However, the goal of the study “was to compare a novel endocrine therapy vs. currently available endocrine therapies,” not combination regimens, the investigators said.
Also, “the benefit of elacestrant over fulvestrant and AIs [aromatase inhibitors] in our monotherapy trial ... suggests that incorporating elacestrant as the preferred endocrine therapy backbone in future earlier-line combination studies is a promising strategy.”
Lipid monitoring necessary
The most common adverse events with elacestrant, occurring in 10% or more of patients, are musculoskeletal pain, nausea, increased cholesterol, increased AST, increased triglycerides, fatigue, decreased hemoglobin, vomiting, increased ALT, decreased sodium, increased creatinine, decreased appetite, diarrhea, headache, constipation, abdominal pain, hot flush, and dyspepsia, according to labeling.
Labeling warns that elacestrant “may cause hypercholesterolemia and hypertriglyceridemia. Monitor lipid profile prior to starting treatment and periodically thereafter.”
The recommended elacestrant dose is the trial dose, 345 mg orally with food once daily until disease progression or unacceptable toxicity.

Poly-(ADP-ribose) polymerase (PARP) inhibitors have emerged as essential therapeutic agents in patients with germline BRCA1/2-mutated BC. A BRCA-like phenotype is displayed by a large subset of patients with germline BRCA1/2-wildtype BC who present with homologous recombination deficiency (HRD). The randomized phase 2 S1416 trial (Rodler et al) evaluated the efficacy of cisplatin combined with the PARP inhibitor veliparib in three cohorts of metastatic BC: mutated germline BRCA1/2, BRCA-like, and non-BRCA–like. A total of 335 patients with metastatic or recurrent triple-negative BC (TNBC) or germline BRCA1/2-mutated metastatic BC were randomly assigned (1:1) to receive cisplatin plus either veliparib or a matching placebo. The findings showed that the addition of veliparib to cisplatin significantly improved progression-free survival (PFS) in patients with BRCA-like metastatic TNBC compared with placebo (5.9 vs 4.2 months; HR 0.57; log-rank P = .01), but not in mutated germline BRCA1/2 (6.2 vs 6.4 months; P = .54) and non-BRCA–like (4.0 vs 3.0 months; P = .57) groups. No new toxicity signals were observed. These findings suggest BRCA-like TNBC might show sensitivity to PARP inhibitors and therefore these agents should be explored further in this cohort.
A recent update from the combined analysis of the SOFT and TEXT studies comparing outcomes in 4690 premenopausal women with estrogen/progesterone receptor–positive early BC (Pagani et al) showed that exemestane plus ovarian function suppression (OFS) led to a greater reduction in recurrence risk compared with tamoxifen plus OFS in premenopausal women. After a median follow-up of 13 years, results showed a 4.6% absolute improvement in 12-year disease-free survival (HR 0.79; P < .001) and a 1.8% absolute improvement in disease recurrence-free interval (HR 0.83; P = .03) with exemestane plus OFS compared with tamoxifen plus OFS. These treatment effects on recurrence began to attenuate over time, being strongest in the first 5 years with no further improvement after 10 or more years. No improvement in overall survival (OS) was noted with exemestane vs tamoxifen, although both arms had excellent survival outcomes (90.1% vs 89.1%; HR 0.93; 95% CI 0.78-1.11). It is important to note that there was a 3.3% absolute improvement in 12-year OS with exemestane plus OFS among patients with HER2-negative tumors who received chemotherapy. This OS benefit was also noted amongst patients with high-risk clinicopathologic characteristics (<35 years and those with > 2 cm or grade 3 tumors), ranging from 4.0% to 5.5% absolute improvement. In conclusion, sustained recurrence risk reductions were noted with adjuvant exemestane plus OFS compared with tamoxifen plus OFS, with the most clinically meaningful survival benefit noted for patients with higher risk tumors. Proper selection of patients who are most likely to benefit from exemestane over tamoxifen is vital to maximize the survival benefit while minimizing the burden of treatment intensification.
Findings from a retrospective study including 221 women with BC who received preoperative neoadjuvant chemotherapy (NAC) showed that the presence of metabolic syndrome (MetS) worsened survival outcomes and increased disease recurrence risk (Zhou et al). Patients were divided into MetS and non-MetS groups according to National Cholesterol Education Program Adult Treatment Panel III criteria to investigate the association between MetS and clinicopathologic characteristics, pathologic complete response (pCR), and long-term survival. The MetS group had a significantly lower likelihood of achieving pCR after NAC compared with the non-MetS group (odds ratio [OR] 0.316; P = .028), with the risk for death (OR 2.587; P = .004) and disease recurrence (OR 2.228; P = .007) being significantly higher in patients with vs without MetS. In a multivariate analysis, MetS (P = 0.028) and hormone receptors status were independent predictors of pCR after NAC in BC. These findings emphasize the importance of timely intervention of metabolic syndrome to improve outcomes in patients with BC.
