TOPLINE:

Oncologists show significant variability in prescribing systemic cancer therapies in the last 30 days of life. Patients treated by oncologists in the top quartile for end-of-life prescribing behavior were almost four and a half times more likely to receive end-of-life therapy than those treated by these specialists in the bottom quartile.

METHODOLOGY:

• Researchers analyzed data from the Surveillance, Epidemiology, and End Results (SEER)-Medicare database, focusing on patients who died of cancer between 2012 and 2017.
• A total of 17,609 patients with breast, lung, colorectal, or prostate cancer were included, treated by 960 oncologists across 388 practices.
• Patients were required to have had at least one systemic cancer therapy claim in the last 180 days of life, with the treating oncologist identified on the basis of the therapy claim closest to the time of death.
• The study used multilevel models to estimate oncologists’ rates of providing cancer therapy in the last 30 days of life, adjusting for patient characteristics and practice variation.
• Functional status was assessed on the basis of paid claims for durable medical equipment in the last 60 months of life, with scores categorized as 0, 1, ≥ 2, or unknown.

TAKEAWAY:

• Oncologists in the 95th percentile for high end-of-life prescribing behavior had a 45% adjusted rate of treating patients in the last 30 days of life, compared with 17% among those in the 5th percentile.
• Patients treated by high end-of-life prescribing oncologists had over four times higher odds of receiving systemic therapy in the last 30 days of life (odds ratio [OR], 4.42; 95% CI, 4.00-4.89).
• Higher end-of-life prescribing oncologists also had a higher proportion of patients hospitalized in the last 30 days of life than low prescribers (58% vs 51.9%).
• No significant association was found between oncologist prescribing behavior and patient race or ethnicity, except for Black patients who had lower odds of receiving treatment (OR, 0.77; P < .001).

IN PRACTICE:

“Given calls to rein in overutilization of end-of-life six to eight cancer therapies, our findings highlight an underappreciated area for further research: How treatment discontinuation before death is shaped by oncologists’ unique treatment propensities. Elucidating the reasons for this remarkable variability in oncologist treatment behavior could inform efforts to reduce end-of-life cancer treatment overutilization,” wrote the authors of the study.

SOURCE:

The study was led by Login S. George, PhD, Institute for Health, Health Care Policy and Aging Research, Rutgers University in New Brunswick, New Jersey. It was published online in Cancer.

LIMITATIONS:

The study’s reliance on SEER-Medicare data may limit the generalizability of the findings to patients with Medicare Advantage, private insurance, or Medicaid, as well as younger patients. The lack of data on patient preferences and other health characteristics could confound the results. The study focused on systemic therapies and may not be generalizable to other treatments such as clinical trial drugs, oral therapies, surgery, or radiation. The data from 2012 to 2017 may not reflect more recent trends in cancer treatment.

DISCLOSURES:

The study was supported by grants from the National Cancer Institute and the Rutgers Cancer Institute of New Jersey. George disclosed receiving grants from these organizations. Additional disclosures are noted in the original article.

Federal officials intend to compel US hospitals to improve obstetrical services, with a plan that could result in a potential loss of Medicare and Medicaid funds for institutions that fail to comply with the demands.

The Centers for Medicare and Medicaid Services (CMS) on July 10 announced this proposal, tucking its plan for new conditions of participation (COP) for obstetrician services into the draft 2025 rule on Medicare payments for outpatient hospital services.

The COP requirements are considered the most powerful tool CMS has for trying to improve the quality of medical care. With the new obstetric COP requirement, CMS said it intends to address what it sees as potential shortfalls in training, staffing, transfer protocols, and emergency services readiness.

In practice, hospitals, CMS, and accrediting bodies such as the Joint Commission usually try to address deficiencies to prevent what would be a devastating financial loss for a hospital.

“CMS is using all of our tools to improve the safety, quality, and timeliness of the care that hospitals provide to pregnant women,” Dora Hughes, MD, MPH, acting chief medical officer of the agency, said in a press release about the proposal.

CMS estimated the proposal may add new annual expenses of $70,671 per hospital. For comparison, this figure would represent far less than 1% of the total $1.4 trillion spent on hospital care in the United States in 2022.

CMS said it is trying to address the reasons women in the United States face more risk in giving birth than those in other nations. There were 22 maternal deaths for every 100,000 live births in this country in 2022, compared with 8.6 deaths per 100,000 live births or lower that year in Canada, France, the United Kingdom, Germany, and Japan, CMS said.

But CMS is seeking to impose this new requirement at a time amid growing concerns about “maternity care deserts.”
 

Reasonable Asks?

Between 2011 and 2021, one out of every four rural hospitals in America stopped providing obstetrics services, Senate Finance Chairman Ron Wyden (D-Ore.) said at a May hearing. Mr. Wyden last year was part of a fight to try to prevent the closure of a birthing center in Baker City in rural eastern Oregon.

The federal government should focus first on helping hospitals keep obstetrical facilities open, said Elizabeth Powers, MD, MHA, the health services officer of the Winding Waters Clinic in Enterprise, Oregon.

“Until we can ensure access to services, we can’t even work on quality,” Dr. Powers told this news organization. “If you’re thinking about a Maslow’s hierarchy of achieving health outcomes, access is your foundation, and without a shift in payment, that foundation is eroded.”

In the draft rule, CMS sketched broad mandates about staffing and training. For example, the agency proposes requiring if a hospital offers obstetrical services, “the services must be well organized and provided in accordance with nationally recognized acceptable standards of practice.”

That means CMS likely will need to provide further guidance for hospitals if it proceeds with this plan for obstetric COP requirements, said Soumi Saha, PharmD, JD, senior vice president of government affairs at Premier Inc., a healthcare consultancy and purchasing organization.

Premier is among the many groups, including the American Hospital Association, that oppose the COP proposal.

Dr. Saha said a better approach would be to consolidate the work being done through the US Department of Health and Human Services (HHS), including earlier CMS projects, to address maternal health in a cohesive way. The Centers for Disease Control and Prevention has programs, as does the HHS Office on Women’s Health.

“How do we really get to a holistic, national, unified approach to addressing this issue that is led by HHS at the top level as the top agency and trickles down consistently versus having all of these kinds of disparate programs in place?” she said.

In recent years, the federal and state governments have taken many steps to try to improve maternal healthcare.

These include the extension of Medicaid benefits to new mothers out to 12 months following delivery in most states. CMS also has encouraged hospitals to participate in voluntary statewide or national programs to improve the quality of perinatal care. Last year the agency launched a “Birthing-Friendly” designation icon for qualifying hospitals on its Care Compare online tool.
 

Support and Opposition

CMS is accepting comments on the draft 2025 hospital outpatient rule, which includes the obstetric COP proposal, through September 9.

Supporters of the obstetric COP approach included the American Nurses Association (ANA), which urged CMS to consider how staffing shortages can undermine patient care in creating COP requirements.

“Nurses are professionals providing critical healthcare services to patients; they should not have to fight for allotted breaks and other challenges created by antiquated views of the profession and payment policies that disincentivize adequate nurse staffing,” Debbie Hatmaker, PhD, RN, ANA’s chief nursing officer, wrote in a June 7 comment to CMS.

The American College of Obstetricians and Gynecologists (ACOG) and the Association of American Medical Colleges (AAMC) also objected to the prospect of new COP for maternal healthcare. They detailed their concerns in separate comments submitted in June 2024.

ACOG said it feared many hospitals might opt to close labor and delivery (L&D) units due to new CMS COP requirements, especially if these take effect “without important and direct stakeholder engagement and buy-in.” More than 200 rural hospitals across the United States stopped providing L&D services in the last decade, Christopher M. Zahn, MD, ACOG’s interim chief executive officer, wrote in a comment to CMS.

“The reason for these closures is varied. Many rural hospitals that still have L&D units continue to lose money on patient services overall, and their ability to continue to deliver maternity care is at risk,” Dr. Zahn wrote.

The AAMC urged CMS to focus on using other strategies such as quality measures to try to improve maternal health and to drop the COP approach. CMS must consider how many clinicians play a role in successful births, including those who see patients during their pregnancies, Jonathan Jaffery, MD, MS, AAMC’s chief healthcare officer, wrote in a comment to the agency.

“Hospitals do have a critical role in improving maternal healthcare equity, especially for labor and delivery outcomes,” he wrote, “but cannot be held solely responsible for implementing much-needed improvements and solutions.”

TOPLINE:

Elevated blood levels of estradiol are associated with an increased risk for corneal ectasia, characterized by thinning and outward bulging of the tissue, in premenopausal women.

METHODOLOGY:

• Researchers conducted an observational case-control study of premenopausal women with naturally occurring corneal ectasia, named keratoconus (n = 36), or those who developed ectasia after refractive surgery (n = 29) from an eye clinic in Israel between 2019 and 2022, and healthy women from hospital staff (n = 31).
• The median age of the participants was 29, 33, and 31 years, respectively.
• Levels of estradiol in the study participants were measured on the second day of their menstrual cycles.

TAKEAWAY:

• The mean levels of estradiol were 38.0 pg/mL in patients with keratoconus, 43.4 pg/mL in those who developed ectasia after surgery, and 28.6 pg/mL in the healthy controls (all P = .001).
• Increased levels of estradiol were associated with corneal ectasia (adjusted odds ratio, 2.44; P < .001).
• Age and use of oral contraceptives were not associated with the risk for corneal ectasia.

IN PRACTICE:

“Our results could have an impact on patient selection for refractive surgery and on better management of patients with keratoconus,” the authors wrote.

SOURCE:

The study was led by Nir Stanescu, MD, of the Department of Ophthalmology at Assuta Samson Hospital, in Ashdod, Israel. It was published online in the European Journal of Ophthalmology.

LIMITATIONS:

The sample size of the study was relatively small. Causality could not be established due to cross-sectional design. The control group consisting of hospital staff may have led to selection bias. The study did not account for factors such as body mass index, diet, smoking status, alcohol consumption, and exercise, which may affect the circulating levels of estradiol.

DISCLOSURES:

The study did not receive any financial support. The authors declared no conflicts of interests.

• The mean levels of estradiol were 38.0 pg/mL in patients with keratoconus, 43.4 pg/mL in those who developed ectasia after surgery, and 28.6 pg/mL in the healthy controls (all P = .001).
• Increased levels of estradiol were associated with corneal ectasia (adjusted odds ratio, 2.44; P < .001).
• Age and use of oral contraceptives were not associated with the risk for corneal ectasia.

IN PRACTICE:

“Our results could have an impact on patient selection for refractive surgery and on better management of patients with keratoconus,” the authors wrote.

SOURCE:

The study was led by Nir Stanescu, MD, of the Department of Ophthalmology at Assuta Samson Hospital, in Ashdod, Israel. It was published online in the European Journal of Ophthalmology.

LIMITATIONS:

The sample size of the study was relatively small. Causality could not be established due to cross-sectional design. The control group consisting of hospital staff may have led to selection bias. The study did not account for factors such as body mass index, diet, smoking status, alcohol consumption, and exercise, which may affect the circulating levels of estradiol.

DISCLOSURES:

The study did not receive any financial support. The authors declared no conflicts of interests.

The CDK4/6 inhibitors abemaciclib and ribociclib were independently associated with better progression-free survival (PFS) when compared with palbociclib in a real-world comparison of the agents as first line treatment, along with endocrine therapy (ET), for patients with hormone receptor–positive, HER2-negative advanced breast cancer.

Lead investigator Claudio Vernieri, MD, PhD, presented these findings of the PALMARES-2 study at the annual meeting of the American Society of Clinical Oncology.

“Along with different safety profiles, drug-drug interactions, and costs of the three available CDK4/6 inhibitor molecules, our efficacy data may help clinicians and patients in choosing the most appropriate CDK4/6 inhibitor in specific clinical contexts,” Dr. Vernieri, who is from the Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, Italy, said during the meeting.

CDK4/6 inhibitors combined with ET, are the standard of care as first line treatment for this population, noted Dr. Vernieri. However, their efficacy has never been directly compared in a large clinical trial.

“Since these compounds have different pharmacokinetics, pharmacodynamics, safety profiles, costs, and drug-drug interactions, identifying which of the three CDK4/6 inhibitors may be more effective in specific clinical contexts is a highly clinically relevant issue,” he said. “Real-world data represent a key source to perform direct comparisons.”

The PALMARES-2 study was a retrospective, multicenter, population-based study, in 18 Italian cancer centers. Its two main objectives were to compare the real-world PFS of abemaciclib versus ribociclib versus palbociclib, in combination with ET, in the whole study cohort, as well as in various subgroups including patients with endocrine-resistant disease, luminal B-like disease, or in premenopausal women.

A total of 1,850 patients (median age, 63 years) were enrolled between January 1, 2016 and September 1, 2023, with 750 (40.6%) receiving palbociclib, and 676 (36.5%) and 424 (22.9%) receiving ribociclib and abemaciclib, respectively.
 

Baseline imbalance

Importantly, there were significant imbalances in baseline characteristics of the patients, with those receiving abemaciclib being more likely to have endocrine-resistant disease, low progesterone receptor expression, and liver metastasis, and less likely to have de novo metastatic disease, compared with other patients, said Dr. Vernieri.

The analysis showed that across the entire cohort, the median real-world PFS and overall survival (OS) were 34.7 months and 66.6 months, respectively, by a January 1, 2024, data cutoff date. “I believe that the overall survival data are still immature to make a definitive conclusion,” he commented, noting that at enrollment only about half of patients had undergone disease progression, and at the close of the study only about 25% had died.

After adjusting for clinically relevant patient- and tumor-related covariates, “we found that both abemaciclib and ribociclib were more effective than palbociclib, whereas we did not find statistically significant differences between abemaciclib and ribociclib,” he reported.

Specifically, the adjusted hazard ratio (aHR) for PFS was 0.71 for abemaciclib versus palbociclib (95% CI, 0.56-0.90; P = .005), 0.81 for ribociclib versus palbociclib (95% CI, 0.65-0.99; P = .048), and 0.91 for abemaciclib versus ribociclib (95% CI, 0.70-1.19; P = .505).

“Regarding subgroup analysis, we found that abemaciclib and ribociclib were more effective than palbociclib in patients with endocrine-resistant or luminal B-like disease, as well as in premenopausal women. Abemaciclib was superior to palbociclib in patients with poorer ECOG [Eastern Cooperative Oncology Group] performance status and to both palbociclib and ribociclib in patients with de novo metastatic disease. Both ribociclib and abemaciclib showed a trend toward higher efficacy in patients with liver metastases. However, this difference only reached statistical significance in patients treated with ribociclib. And finally, the three CDK4/6 inhibitors were similarly effective in patients who were older or at bone-only disease,” he concluded.
 

Justifying adjustment

Speaking during the audience question period Giuseppe Del Priore, MD, from Morehouse School of Medicine in Atlanta, Georgia, said he preferred unadjusted results when examining real-world data, “because that’s the benefit,” and he questioned why the researchers had adjusted their numbers.

Dr. Vernieri explained that the adjustments were made to account for the important imbalances in the baseline characteristics of the patients.

“When we plotted unadjusted curves, we did not find statistically significant differences between these three drugs, only a trend toward the direction that I showed you today,” he said. “However, as you saw from the tables showing the characteristics of patients, there were important imbalances in terms of important prognostic factors in the three patient cohorts. So, I think that, for this kind of data and based on this level of imbalance, adjustment is necessary.

“To reinforce our conclusions, what we did was also to perform a propensity score match–based analysis,” Dr. Vernieri continued. “I did not have the time to show the results today, but these data were fully in line with the study conclusions. And we also performed a backward selection of variables. So, we basically selected variables more likely to be associated with patient prognosis. And also those models confirm the study conclusion. So I think the conclusions are quite solid.”

Dr. Del Priore, an adjunct professor of obstetrics and gynecology with a specialty in oncology, on the other hand, said he was not convinced that any of the drugs might be better or worse in the actual population treated.

“I still maintain that unadjusted real-world data should be presented and then only a limited adjusted analysis performed using the most unbalanced variables,” he said. “To do more elaborate adjustments may falsely imply a difference in drug choice and outcomes which never should be the conclusion with observational studies. Instead, the conclusions should be that, with typical use, the following similarities in PFS and OS were observed. Then point out how drug choice and important prognostic variables might be linked, thus limiting the generalizable conclusions even further.

“I would conclude that prospective studies should balance for the variables used in the PALMARES-2 analyses, which actually may have been chosen for adjustment post hoc,” Dr. Del Priore said.

The study was funded by the Italian Association for Cancer Research, the European Research Council, the Ministero della Salute, the Scientific Directorate of Fondazione IRCCS Istituto Nazionale dei Tumori, Giuliani’s Foundation and Roche. Dr. Vernieri reported consulting or advisory roles with Daiichi Sankyo/Astra Zeneca, Novartis, and Pfizer; speakers’ bureau roles with Accademia Nazionale Di Medicina (ACCMED), Istituto Gentili, Lilly and Novartis; and research funding from Roche. Dr. Del Priore reported no conflicts of interest and disclosed that he is chief medical officer at BriaCell.

TOPLINE:

Patients with stage I triple-negative breast cancer (TNBC) who have higher levels of stromal tumor-infiltrating lymphocytes (TILs) demonstrate “excellent” 10-year breast cancer–specific survival without chemotherapy, according to new findings, which suggest that stromal TILs could be a useful biomarker to optimize treatment decisions in this patient population.

METHODOLOGY:

• The absolute benefit of chemotherapy remains unclear among patients with stage I TNBC. High levels of stromal TILs, a promising biomarker, have been linked to better survival in patients with TNBC, but data focused on stage I disease are lacking.
• In the current analysis, researchers identified a cohort of 1041 women (mean age at diagnosis, 64.4 years) from the Netherlands Cancer Registry with stage I TNBC who had an available TIL score and had undergone a lumpectomy or a mastectomy but had not received neoadjuvant or adjuvant chemotherapy.
• Patients’ clinical data were matched to their corresponding pathologic data provided by the Dutch Pathology Registry, and a pathologist blinded to outcomes scored stromal TIL levels according to the International Immuno-Oncology Biomarker Working Group guidelines.
• The primary endpoint was breast cancer–specific survival at prespecified stromal TIL cutoffs of 30%, 50%, and 75%. Secondary outcomes included specific survival by pathologic tumor stage and overall survival.

TAKEAWAY:

• Overall, 8.6% of women had a pT1a tumor, 38.7% had a pT1b tumor, and 52.6% had a pT1c tumor. In the cohort, 25.6% of patients had stromal TIL levels of 30% or higher, 19.5% had levels of 50% or higher, and 13.5% had levels of 75% or higher.
• Over a median follow-up of 11.4 years, 335 patients died, 107 (32%) of whom died from breast cancer. Patients with smaller tumors (pT1abNO) had better survival outcomes than those with larger tumors (pT1cNO) — a 10-year breast cancer–specific survival of 92% vs 86%, respectively.
• In the overall cohort, stromal TIL levels of 30% or higher were associated with better breast cancer–specific survival than those with stromal TIL levels below 30% (96% vs 87%; hazard ratio [HR], 0.45). Stromal TIL levels of 50% or greater were also associated with better 10-year breast cancer–specific survival than those with levels below 50% (92% vs 88%; HR, 0.59). A similar pattern was observed for stromal TIL levels and overall survival.
• In patients with pT1c tumors, the 10-year breast cancer–specific survival among those with stromal TIL levels of 30% or higher was 95% vs 83% for levels below the 30% cutoff (HR, 0.24). Similarly, the 10-year breast cancer–specific survival for those in the 50% or higher group was 95% vs 84% for levels below that cutoff (HR, 0.27). The 10-year breast cancer–specific survival improved to 98% among patients with stromal TIL levels of 75% or higher (HR, 0.09).

IN PRACTICE:

The results supported the establishment of “treatment-optimization clinical trials in patients with stage I TNBC, using [stromal] TIL level as an integral biomarker to prospectively confirm the observed excellent survival when neoadjuvant or adjuvant chemotherapy is not administered,” the authors wrote. Assessing stromal TILs is also “inexpensive,” the authors added.

SOURCE:

The research, conducted by Marleen Kok, MD, PhD, Department of Medical Oncology, the Netherlands Cancer Institute, Amsterdam, and colleagues, was published online in JAMA Oncology.

LIMITATIONS:

The authors noted that the study was limited by its observational nature. The patients were drawn from a larger cohort, about half of whom received adjuvant chemotherapy, and the patients who did not receive chemotherapy may have had favorable tumor characteristics. There were also no data on BRCA1 or BRCA2 germline mutation status and recurrences and/or distant metastases. The database did not include data on patient ethnicity because most Dutch patients were White.

DISCLOSURES:

Research at the Netherlands Cancer Institute was supported by institutional grants from the Dutch Cancer Society and the Dutch Ministry of Health, Welfare and Sport. Dr. Kok declared financial relationships with several organizations including Gilead and Domain Therapeutics, as well as institutional grants from AstraZeneca, BMS, and Roche. Other authors also declared numerous financial relationships for themselves and their institutions with pharmaceutical companies.

• In patients with pT1c tumors, the 10-year breast cancer–specific survival among those with stromal TIL levels of 30% or higher was 95% vs 83% for levels below the 30% cutoff (HR, 0.24). Similarly, the 10-year breast cancer–specific survival for those in the 50% or higher group was 95% vs 84% for levels below that cutoff (HR, 0.27). The 10-year breast cancer–specific survival improved to 98% among patients with stromal TIL levels of 75% or higher (HR, 0.09).

IN PRACTICE:

The results supported the establishment of “treatment-optimization clinical trials in patients with stage I TNBC, using [stromal] TIL level as an integral biomarker to prospectively confirm the observed excellent survival when neoadjuvant or adjuvant chemotherapy is not administered,” the authors wrote. Assessing stromal TILs is also “inexpensive,” the authors added.

SOURCE:

The research, conducted by Marleen Kok, MD, PhD, Department of Medical Oncology, the Netherlands Cancer Institute, Amsterdam, and colleagues, was published online in JAMA Oncology.

LIMITATIONS:

The authors noted that the study was limited by its observational nature. The patients were drawn from a larger cohort, about half of whom received adjuvant chemotherapy, and the patients who did not receive chemotherapy may have had favorable tumor characteristics. There were also no data on BRCA1 or BRCA2 germline mutation status and recurrences and/or distant metastases. The database did not include data on patient ethnicity because most Dutch patients were White.

DISCLOSURES:

Research at the Netherlands Cancer Institute was supported by institutional grants from the Dutch Cancer Society and the Dutch Ministry of Health, Welfare and Sport. Dr. Kok declared financial relationships with several organizations including Gilead and Domain Therapeutics, as well as institutional grants from AstraZeneca, BMS, and Roche. Other authors also declared numerous financial relationships for themselves and their institutions with pharmaceutical companies.

CHICAGO — Being hormone receptor positive is generally a favorable prognostic factor in breast cancer, but that doesn’t seem to be the case in women with BRCA-associated tumors, according to a study presented at the American Society of Clinical Oncology annual meeting.

The conclusion is based on a large international study on how hormone receptor status impacts breast cancer outcomes in young women with germline BRCA pathological variants (PVs).

Overall, “hormone receptor positivity did not seem to have a strong positive prognostic value in young BRCA carriers” with early breast cancer, lead investigator Luca Arecco, MD, an oncology resident at the University of Genoa, Italy, said at the meeting.

Investigators reviewed the records of 4709 women ages 40 years or younger with stage 1-3 BRCA-associated invasive breast cancer treated from 2000 to 2020 at 78 centers in 28 countries across four continents. Median follow-up was about 8 years.
 

Weaker Prognostic Value in Hormone Receptor Status

They found, in general, that hormone receptor–positive breast cancer appears to be biologically more aggressive in patients with BRCA PVs than in the general breast cancer population, generating outcomes similar to those with hormone receptor-negative BRCA tumors.

Specifically, among patients with germline BRCA PVs, while hormone receptor–positive patients had a higher distant recurrence rate (13.1% vs. 9.6%) than hormone receptor–negative patients, 8-year disease free survival (65.8% and 63.4% respectively) and overall survival (a bit under 90% in both groups) were similar.

Hormone receptor–positive patients did have a lower rate of second primary breast cancers (9.1% versus 14.7%).

In the formal write-up of the results published shortly after the meeting in Annals of Oncology, the investigators concluded that “in young BRCA carriers, differences in recurrence pattern and second primary breast cancer among hormone receptor–positive versus negative disease warrant consideration in counseling patients on treatment, follow-up, and risk-reducing surgery.”

The team also found other differences between BRCA-associated breast cancer and sporadic disease. For instance, in the BRCA cohort, luminal A-like breast cancer had a worse long-term prognosis in their BRCA cohort than triple-negative or HER2-positive disease. Luminal A-like tumors are generally considered less aggressive, but in patients with BRCA PVs, “improving neoadjuvant chemotherapy … could be worthwhile,” the investigators said.

Also, although the risk of recurrence for sporadic hormone receptor–negative tumors is highest in the first few years, the team found that the risk in the hormone negative BRCA cohort progressively increased with longer follow-up, driven by the occurrence of second primary breast cancers, especially in patients with BRCA 1 PVs.
 

Greater Clarity in Prognosis in BRCA-Associated Breast Cancer

Overall, study discussant Lisa A. Carey, MD, a breast cancer specialist at the University of North Carolina at Chapel Hill, said, “we now know much more clearly the issues of prognosis in women who are very young and have germline BRCA-associated breast cancer,” about 12% of newly diagnosed cases.

“Young patients with germline BRCA-associated breast cancers have high relapse and high new primary risks, warranting comprehensive multimodality therapy,” she said.

A bit fewer than half of women in the study were hormone receptor–positive, and they tended to be patients with BRCA 2 PVs. The rest were hormone receptor–negative and tended to have BRCA 1 PVs.

Patients with hormone receptor–positive disease had grade 3 cancers in about 50% of cases, while patients with hormone receptor–negative disease had a grade 3 disease in over 80%.

Hormone receptor–positive patients were more likely to have nodal involvement and undergo mastectomies but less likely to receive chemotherapy than hormone receptor–negative patients. It’s likely that few patients in the review received PARP inhibitors, Dr. Carey noted.

Although overall survival at 8 years was similar in both groups, after that point “the prognosis of patients with hormone receptor–positive disease appeared to be worse … This appeared to occur earlier than that described in sporadic disease,” in which the worsening of survival in hormone receptor–positive disease occurs after a follow-up of at least 14-15 years, the investigators noted in their journal report.

The work was funded by the Italian Association for Cancer Research, Institut Jules Bordet, Korea Health Industry Development Institute, Australian National Health and Medical Council, Cancer Australia, US National Institute of Health, and others. Dr. Arecco had no disclosures. Dr. Carey and other coauthors disclosed research funding, speaker honoraria, and other financial relationships with AstraZeneca, Genentech/Roche, Lilly, and other pharmaceutical companies.

Black metastatic breast cancer patients with PIK3CA mutations were less likely to receive targeted therapy and less likely to be enrolled in clinical trials than White patients and had shorter overall survival, according to a retrospective cohort study. Black and White patients were equally likely to receive other drugs that did not require genomic testing.

“These clinical inequities in the use of targeted therapies and clinical trials ... must be a focus going forward,” said lead investigator Emily Podany, MD, a clinical fellow in hematology-oncology at Washington University in St. Louis, Missouri. “Our consortium is looking for paths forward in order to try and decrease these striking inequities. And it’s a focus of future research for us and future implementation [of] science interventions, hopefully, across the country.”

The study results were presented at the annual meeting of the American Society of Clinical Oncology.
 

Black Women Underrepresented

Black women are generally underrepresented in clinical trials, noted Dr. Podany. “They make up about 2%-5% of the patients in breast cancer clinical trials, and there are documented inequities in treatment and in outcomes for Black patients with metastatic breast cancer. This includes longer treatment delays, it includes fewer sentinel lymph node biopsies, and unfortunately, they’re more likely to discontinue treatment early.”

In terms of PI3K inhibition, PIK3CA mutations are found in about 40% of patients with HR-positive HER2-negative metastatic breast cancer. Alpelisib is FDA-approved as a targeted therapy for these patients, she said.

The study evaluated records of 1327 patients with metastatic breast cancer who also had circulating tumor DNA (ctDNA) results and were treated at Washington University, Massachusetts General Hospital in Boston, and Northwestern University in Chicago. Of these, 795 had an ER-positive, HER2-negative subtype and were included in the analysis. Most (89%) of the patients were White (n = 708), while 11% (n = 87) were Black, and the only baseline difference between patients was that Black patients had significantly more de novo metastatic breast cancer (31% versus 22%).

Use of PI3K, CDK4/6, or mTOR inhibitors was evaluated using manual electronic medical review, and genomic differences were evaluated using logistic regression.

The analysis showed inequities in both treatment and clinical trial enrollment. There were no differences between groups in the use of CDK4/6 or mTOR inhibitors, which do not require a genomic profile, the researchers noted, but Black patients with PIK3CA single nucleotide variants (SNV) were significantly less likely than White patients to use PI3K inhibitors (5.9% versus 28.8%; P = .045), despite no difference in PIK3CA mutations between groups (36% and 34% respectively). Similarly, 11% of White patients with PIK3CA mutations were enrolled in clinical trials, but none of the Black patients was.

Genomic differences were also found, Dr. Podany reported. Black patients with estrogen/progesterone receptor (ER/PR) positive, HER2-negative disease were more likely to have a CCND1 copy number variant. And for ER-positive PR-negative HER2-negative patients, Black patients were more likely to have a GATA3 SNV, while White patients were more likely to have a KRAS copy number variant.
 

Black Survival Less Than Half

The analysis also found significant differences in overall survival from the time of the first liquid biopsy, with White ER-positive, PR-negative, HER2-negative patients living a median of 21 months, versus 9.1 months for Black patients.

There were several limitations to the study beyond its retrospective nature, “so, we may be underestimating the true inequity,” noted Dr. Podany. “These are large urban academic centers, so our patients have access to these treatments. They have access to care. They have access to ctDNA liquid biopsy testing. And the timing of ctDNA, especially the first ctDNA test, is variable and provider-dependant. We were also unable to assess receipt of PI3 kinase inhibitors at future time points after the end of this cohort study.”

Asked for comment, Giuseppe Del Priore, MD, MPH, from Morehouse School of Medicine in Atlanta, Georgia, approved of the study design “with subjects limited to three distinctive institutions. That parameter alone can control for several unknown variables among the studied comparison groups, ie, Black women versus others.”

However, Dr. Del Priore, who is adjunct professor of obstetrics and gynecology, with a specialty in oncology, added, “retrospective studies are not reliable except for generating hypotheses. Therefore, I would like to see a rapid implementation of an intervention trial at these same institutions to ensure equal consideration of, and access to, targeted therapies. Too often a retrospective correlation is reported, but the solution is elusive due to unknown factors. In this case, knowing there is a mutation is far from alleviating the disproportionate burden of disease that many communities face.”

Dr. Podany had no relevant disclosures. Dr. Del Priore reported no conflicts of interest and disclosed that he is chief medical officer at BriaCell.

CHICAGO — Circulating tumor DNA (ctDNA) can predict relapse risk in some cases of early, high-risk breast cancer, but it’s too soon to use it to guide adjuvant therapy decisions, according to a study presented at the American Society of Clinical Oncology annual meeting.

Detectable ctDNA is “highly prognostic of worse outcomes, particularly in patients who [remain] persistently positive,” but the correlation isn’t perfect, said lead investigator Sherene Loi, MMBS, PhD, a breast cancer specialist at the Peter MacCallum Cancer Centre in Melbourne, Australia.

Although less likely, relapses also occurred in the study among women without ctDNA elevation. Conversely, there were women with elevated ctDNA who did not relapse, she said. The study was a subanalysis of the monarchE trial of adjuvant abemaciclib, a CDK 4/6 inhibitor.

Eventually, “we would like to use” ctDNA to guide adjuvant treatment decisions, but the research isn’t there yet, Dr. Loi said. It’s possible, for instance, that persistently detectable ctDNA indicates early treatment failure and the need for treatment intensification. Future research should tackle the issue.

Study discussant Francois-Clement Bidard, MD, PhD, a breast cancer specialist at Institut Curie, Paris, agreed that ctDNA isn’t ready for primetime in adjuvant early, high-risk breast cancer.

“There is no clinical evidence to suggest that there is clinical utility in this setting. There are several trials that are ongoing,” he said, but for now “you shouldn’t,” for example, “use ctDNA to de-escalate adjuvant CDK4/6 [inhibitors]. It could be in the future that we could have data on this, but at the moment, [the] clear clinical message [is] no way.”

At 5-year follow-up, the monarchE trial found a 7.6% invasive disease-free survival (IDFS) improvement when abemaciclib was added to the first 2 years of endocrine therapy in women with HR+, HER2-, node positive, high-risk early breast cancer. The combination is now a standard adjuvant option for the disease.

The ctDNA study focused on a subset of 910 subjects with adequate ctDNA testing to run the analysis. The study population was also selected to be enriched for overall IDFS events (27% versus 18% across the trial’s 5,637 subjects). An IDFS event was defined as a local, regional, contralateral or distant invasive recurrence; a new primary tumor; or death from any cause.

Testing was performed using the Signatera ctDNA assay. Baseline samples were taken after completion of adjuvant chemotherapy, then again at 3, 6, or 24 months.

Overall, ctDNA detection was infrequent. Just 8% of patients were positive at baseline and 17% were positive at any point during the trial. Even so, ctDNA detection at any point was adversely prognostic.

Patients who were ctDNA positive at baseline were more likely to experience an IDFS event, compared with those who were ctDNA negative at baseline (80% at 4 years follow-up versus 23%).

Similarly, those who remained positive or became positive during testing were more likely to experience an IDFS event compared with those who became negative or remained negative throughout testing.

For instance, all 34 patients who were positive at baseline and remained positive had an IDFS event by year 4, versus just 40% who started positive but then cleared their ctDNA.

Among women who were negative at baseline and remained negative, 13% had an IDFS event versus 89% who started negative but then turned positive. Subjects who turned positive also had the shortest time to an IDFS event, a median of 7 months.

Among women who recurred, those who were ctDNA negative tended to have local, regional, or contralateral recurrences, while ctDNA positive patients tended to have distant recurrences.

The finding “really highlights that ctDNA antedates the metastatic clinical relapse. What the ctDNA is telling you is that the metastatic process has been completed, and metastases are about to grow,” Dr. Bidard said.

CHICAGO — Circulating tumor DNA (ctDNA) can predict relapse risk in some cases of early, high-risk breast cancer, but it’s too soon to use it to guide adjuvant therapy decisions, according to a study presented at the American Society of Clinical Oncology annual meeting.

Detectable ctDNA is “highly prognostic of worse outcomes, particularly in patients who [remain] persistently positive,” but the correlation isn’t perfect, said lead investigator Sherene Loi, MMBS, PhD, a breast cancer specialist at the Peter MacCallum Cancer Centre in Melbourne, Australia.

Although less likely, relapses also occurred in the study among women without ctDNA elevation. Conversely, there were women with elevated ctDNA who did not relapse, she said. The study was a subanalysis of the monarchE trial of adjuvant abemaciclib, a CDK 4/6 inhibitor.

Eventually, “we would like to use” ctDNA to guide adjuvant treatment decisions, but the research isn’t there yet, Dr. Loi said. It’s possible, for instance, that persistently detectable ctDNA indicates early treatment failure and the need for treatment intensification. Future research should tackle the issue.

Study discussant Francois-Clement Bidard, MD, PhD, a breast cancer specialist at Institut Curie, Paris, agreed that ctDNA isn’t ready for primetime in adjuvant early, high-risk breast cancer.

“There is no clinical evidence to suggest that there is clinical utility in this setting. There are several trials that are ongoing,” he said, but for now “you shouldn’t,” for example, “use ctDNA to de-escalate adjuvant CDK4/6 [inhibitors]. It could be in the future that we could have data on this, but at the moment, [the] clear clinical message [is] no way.”

At 5-year follow-up, the monarchE trial found a 7.6% invasive disease-free survival (IDFS) improvement when abemaciclib was added to the first 2 years of endocrine therapy in women with HR+, HER2-, node positive, high-risk early breast cancer. The combination is now a standard adjuvant option for the disease.

The ctDNA study focused on a subset of 910 subjects with adequate ctDNA testing to run the analysis. The study population was also selected to be enriched for overall IDFS events (27% versus 18% across the trial’s 5,637 subjects). An IDFS event was defined as a local, regional, contralateral or distant invasive recurrence; a new primary tumor; or death from any cause.

Testing was performed using the Signatera ctDNA assay. Baseline samples were taken after completion of adjuvant chemotherapy, then again at 3, 6, or 24 months.

Overall, ctDNA detection was infrequent. Just 8% of patients were positive at baseline and 17% were positive at any point during the trial. Even so, ctDNA detection at any point was adversely prognostic.

Patients who were ctDNA positive at baseline were more likely to experience an IDFS event, compared with those who were ctDNA negative at baseline (80% at 4 years follow-up versus 23%).

Similarly, those who remained positive or became positive during testing were more likely to experience an IDFS event compared with those who became negative or remained negative throughout testing.

For instance, all 34 patients who were positive at baseline and remained positive had an IDFS event by year 4, versus just 40% who started positive but then cleared their ctDNA.

Among women who were negative at baseline and remained negative, 13% had an IDFS event versus 89% who started negative but then turned positive. Subjects who turned positive also had the shortest time to an IDFS event, a median of 7 months.

Among women who recurred, those who were ctDNA negative tended to have local, regional, or contralateral recurrences, while ctDNA positive patients tended to have distant recurrences.

The finding “really highlights that ctDNA antedates the metastatic clinical relapse. What the ctDNA is telling you is that the metastatic process has been completed, and metastases are about to grow,” Dr. Bidard said.

TOPLINE:

The transvaginal ultrasonography triage strategy is unreliable for diagnosing endometrial cancer in high-risk Black women, with a significant risk for false-negative results at different endometrial thickness thresholds.

METHODOLOGY:

• Poor performance of transvaginal ultrasonography-measured endometrial thickness as a diagnostic triage strategy for endometrial cancer may contribute to racial disparity in stage at diagnosis between Black and White women.
• Researchers assessed the false-negative probability using transvaginal ultrasonography-measured endometrial thickness thresholds as triage for endometrial cancer in 1494 Black women (median age, 46 years) who underwent hysterectomy.
• The researchers focused on endometrial thickness measurements recorded within 24 months before hysterectomy, as well as demographic and clinical data.
• The endometrial thickness thresholds were defined as < 3 mm, < 4 mm, and < 5 mm, with the rest grouped as ≥ 5 mm, consistent with guidelines.
• A total of 210 women had endometrial cancer. The most common presenting symptoms were fibroids (78%), vaginal bleeding (71%), and pelvic pain (57%).

TAKEAWAY:

• Twenty-four cases of endometrial cancer were below the 5-mm endometrial thickness threshold that would trigger biopsy, resulting overall in 11.4% of endometrial cancer cases potentially missed.
• The false-negative probability was 9.5% (20 cases) at the < 4-mm threshold and 3.8% (8 cases) at the < 3-mm threshold.
• Classic risk factors for endometrial cancer (postmenopausal bleeding, age ≥ 50 years, and BMI > 40) did not result in improved performance of the endometrial thickness triage strategy.
• False-negative probability was also similar among those with fibroids (12%) but higher in the setting of partial endometrial thickness visibility (26%) and pelvic pain (15%).

IN PRACTICE:

This study reveals a “concerning error rate for a triage strategy that would terminate further workup and provide false reassurance to both patients and physicians.” The results contribute to “an increasing body of work questioning the wisdom of the (transvaginal ultrasonography) triage strategy. It may be the case that the (transvaginal ultrasonography) triage for endometrial biopsy is no longer a preferred strategy in the setting of increasing endometrial cancer rates for all. For Black patients with concerning symptoms, tissue biopsy is recommended to avoid misdiagnosis of endometrial cancer,” the researchers concluded.

SOURCE:

The study, with first author Kemi M. Doll, MD, Fred Hutchinson Cancer Center, University of Washington, Seattle, was published online in JAMA Oncology.

LIMITATIONS:

The study did not include cases where transvaginal ultrasonography reports omitted endometrial thickness measurements or reported nonvisible endometrial thickness, possibly underestimating the failure rate of the transvaginal ultrasonography triage strategy.

The sample did not include endometrial cancer cases that were not treated with hysterectomy, which may occur in young women with grade 1 endometrial cancer, those medically incapable of undergoing surgery, and those with disease so advanced that surgery is no longer an option. 
 

DISCLOSURES:

Funding was provided by Kuni Discovery Grants for Cancer Research: Advancing Innovation and by a grant from the National Institutes of Health. Dr. Doll reported receiving investigator-initiated research grants from the Patient Centered Outcomes Research Institute, American Association of Cancer Research, and Merck.

For 3 years, Ajala Efem’s type 2 diabetes was so poorly controlled that her blood sugar often soared northward of 500 mg/dL despite insulin shots three to five times a day. She would experience dizziness, vomiting, severe headaches, and the neuropathy in her feet made walking painful. She was also — literally — frothing at the mouth. The 47-year-old single mother of two adult children with mental disabilities feared that she would die.

Ms. Efem lives in the South Bronx, which is among the poorest areas of New York City, where the combined rate of prediabetes and diabetes is close to 30%, the highest rate of any borough in the city.

She had to wait 8 months for an appointment with an endocrinologist, but that visit proved to be life-changing. She lost 28 pounds and got off 15 medications in a single month. She did not join a gym or count calories; she simply changed the food she ate and adopted a low-carb diet.

“I went from being sick to feeling so great,” she told her endocrinologist recently: “My feet aren’t hurting; I’m not in pain; I’m eating as much as I want, and I really enjoy my food so much.” 

Ms. Efem’s life-changing visit was with Mariela Glandt, MD, at the offices of Essen Health Care. One month earlier, Dr. Glandt’s company, OwnaHealth, was contracted by Essen to conduct a 100-person pilot program for endocrinology patients. Essen is the largest Medicaid provider in New York City, and “they were desperate for an endocrinologist,” said Dr. Glandt, who trained at Columbia University in New York. So she came — all the way from Madrid, Spain. She commutes monthly, staying for a week each visit.

Dr. Glandt keeps up this punishing schedule because, as she explains, “it’s such a high for me to see these incredible transformations.” Her mostly Black and Hispanic patients are poor and lack resources, yet they lose significant amounts of weight, and their health issues resolve.

“Food is medicine” is an idea very much in vogue. The concept was central to the landmark White House Conference on Hunger, Nutrition, and Health in 2022 and is now the focus of a number of a wide range of government programs. Recently, the Senate held a hearing aimed at further expanding food as medicine programs.

Still, only a single randomized controlled clinical trial has been conducted on this nutritional approach, with unexpectedly disappointing results. In the mid-Atlantic region, 456 food-insecure adults with type 2 diabetes were randomly assigned to usual care or the provision of weekly groceries for their entire families for about 1 year. Provisions for a Mediterranean-style diet included whole grains, fruits and vegetables, lean protein, low-fat dairy products, cereal, brown rice, and bread. In addition, participants received dietary consultations. Yet, those who got free food and coaching did not see improvements in their average blood sugar (the study’s primary outcome), and their low-density lipoprotein (LDL) cholesterol and high-density lipoprotein (HDL) cholesterol levels appeared to have worsened. 

“To be honest, I was surprised,” the study’s lead author, Joseph Doyle, PhD, professor at the Sloan School of Management at MIT in Cambridge, Massachusetts, told me. “I was hoping we would show improved outcomes, but the way to make progress is to do well-randomized trials to find out what works.”

I was not surprised by these results because a recent rigorous systematic review and meta-analysis in The BMJ did not show a Mediterranean-style diet to be the most effective for glycemic control. And Ms. Efem was not in fact following a Mediterranean-style diet.

Ms. Efem’s low-carb success story is anecdotal, but Dr. Glandt has an established track record from her 9 years’ experience as the medical director of the eponymous diabetes center she founded in Tel Aviv. A recent audit of 344 patients from the center found that after 6 months of following a very low–carbohydrate diet, 96.3% of those with diabetes saw their A1c fall from a median 7.6% to 6.3%. Weight loss was significant, with a median drop of 6.5 kg (14 pounds) for patients with diabetes and 5.7 kg for those with prediabetes. The diet comprises 5%-10% of calories from carbs, but Dr. Glandt does not use numeric targets with her patients.

Blood pressure, triglycerides, and liver enzymes also improved. And though LDL cholesterol went up by 8%, this result may have been offset by an accompanying 13% rise in HDL cholesterol. Of the 78 patients initially on insulin, 62 were able to stop this medication entirely.

Although these results aren’t from a clinical trial, they’re still highly meaningful because the current dietary standard of care for type 2 diabetes can only slow the progression of the disease, not cause remission. Indeed, the idea that type 2 diabetes could be put into remission was not seriously considered by the American Diabetes Association (ADA) until 2009. By 2019, an ADA report concluded that “[r]educing overall carbohydrate intake for individuals with diabetes has demonstrated the most evidence for improving glycemia.” In other words, the best way to improve the key factor in diabetes is to reduce total carbohydrates. Yet, the ADA still advocates filling one quarter of one’s plate with carbohydrate-based foods, an amount that will prevent remission. Given that the ADA’s vision statement is “a life free of diabetes,” it seems negligent not to tell people with a deadly condition that they can reverse this diagnosis. 

A 2023 meta-analysis of 42 controlled clinical trials on 4809 patients showed that a very low–carbohydrate ketogenic diet (keto) was “superior” to alternatives for glycemic control. A more recent review of 11 clinical trials found that this diet was equal but not superior to other nutritional approaches in terms of blood sugar control, but this review also concluded that keto led to greater increases in HDL cholesterol and lower triglycerides. 

Dr. Glandt’s patients in the Bronx might not seem like obvious low-carb candidates. The diet is considered expensive and difficult to sustain. My interviews with a half dozen patients revealed some of these difficulties, but even for a woman living in a homeless shelter, the obstacles are not insurmountable.

Jerrilyn, who preferred that I use only her first name, lives in a shelter in Queens. While we strolled through a nearby park, she told me about her desire to lose weight and recover from polycystic ovary syndrome, which terrified her because it had caused dramatic hair loss. When she landed in Dr. Glandt’s office at age 28, she weighed 180 pounds. 

Less than 5 months later, Jerrilyn had lost 25 pounds, and her period had returned with some regularity. She said she used “food stamps,” known as the Supplemental Nutrition Assistance Program (SNAP), to buy most of her food at local delis because the meals served at the shelter were too heavy in starches. She starts her day with eggs, turkey bacon, and avocado. 

“It was hard to give up carbohydrates because in my culture [Latina], we have nothing but carbs: rice, potatoes, yuca,” Jerrilyn shared. She noticed that carbs make her hungrier, but after 3 days of going low-carb, her cravings diminished. “It was like getting over an addiction,” she said.

Jerrilyn told me she’d seen many doctors but none as involved as Dr. Glandt. “It feels awesome to know that I have a lot of really useful information coming from her all the time.” The OwnaHealth app tracks weight, blood pressure, blood sugar, ketones, meals, mood, and cravings. Patients wear continuous glucose monitors and enter other information manually. Ketone bodies are used to measure dietary adherence and are obtained through finger pricks and test strips provided by OwnaHealth. Dr. Glandt gives patients her own food plan, along with free visual guides to low-carbohydrate foods by dietdoctor.com. 

Dr. Glandt also sends her patients for regular blood work. She says she does not frequently see a rise in LDL cholesterol, which can sometimes occur on a low-carbohydrate diet. This effect is most common among people who are lean and fit. She says she doesn’t discontinue statins unless cholesterol levels improve significantly.

Samuel Gonzalez, age 56, weighed 275 pounds when he walked into Dr. Glandt’s office this past November. His A1c was 9.2%, but none of his previous doctors had diagnosed him with diabetes. “I was like a walking bag of sugar!” he joked. 

A low-carbohydrate diet seemed absurd to a Puerto Rican like himself: “Having coffee without sugar? That’s like sacrilegious in my culture!” exclaimed Mr. Gonzalez. Still, he managed, with SNAP, to cook eggs and bacon for breakfast and some kind of protein for dinner. He keeps lunch light, “like tuna fish,” and finds checking in with the OwnaHealth app to be very helpful. “Every day, I’m on it,” he said. In the past 7 months, he’s lost 50 pounds, normalized his cholesterol and blood pressure levels, and lowered his A1c to 5.5%.

Mr. Gonzalez gets disability payments due to a back injury, and Ms. Efem receives government payments because her husband died serving in the military. Ms. Efem says her new diet challenges her budget, but Mr. Gonzalez says he manages easily.

Mélissa Cruz, a 28-year-old studying to be a nail technician while also doing back office work at a physical therapy practice, says she’s stretched thin. “I end up sad because I can’t put energy into looking up recipes and cooking for me and my boyfriend,” she told me. She’ll often cook rice and plantains for him and meat for herself, but “it’s frustrating when I’m low on funds and can’t figure out what to eat.” 

Low-carbohydrate diets have a reputation for being expensive because people often start eating pricier foods, like meat and cheese, to replace cheaper starchy foods such as pasta and rice. Eggs and ground beef are less expensive low-carb meal options, and meat, unlike fruits and vegetables, is easy to freeze and doesn’t spoil quickly. These advantages can add up.

A 2019 cost analysis published in Nutrition & Dietetics compared a low-carbohydrate dietary pattern with the New Zealand government’s recommended guidelines (which are almost identical to those in the United States) and found that it cost only an extra $1.27 in US dollars per person per day. One explanation is that protein and fat are more satiating than carbohydrates, so people who mostly consume these macronutrients often cut back on snacks like packaged chips, crackers, and even fruits. Also, those on a ketogenic diet usually cut down on medications, so the additional $1.27 daily is likely offset by reduced spending at the pharmacy.

It’s not just Bronx residents with low socioeconomic status (SES) who adapt well to low-carbohydrate diets. Among Alabama state employees with diabetes enrolled in a low-carbohydrate dietary program provided by a company called Virta, the low SES population had the best outcomes. Virta also published survey data in 2023 showing that participants in a program with the Veteran’s Administration did not find additional costs to be an obstacle to dietary adherence. In fact, some participants saw cost reductions due to decreased spending on processed snacks and fast foods.

Ms. Cruz told me she struggles financially, yet she’s still lost nearly 30 pounds in 5 months, and her A1c went from 7.1% down to 5.9%, putting her diabetes into remission. Equally motivating for her are the improvements she’s seen in other hormonal issues. Since childhood, she’s had acanthosis, a condition that causes the skin to darken in velvety patches, and more recently, she developed severe hirsutism to the point of growing sideburns. “I had tried going vegan and fasting, but these just weren’t sustainable for me, and I was so overwhelmed with counting calories all the time.” Now, on a low-carbohydrate diet, which doesn’t require calorie counting, she’s finally seeing both these conditions improve significantly.

When I last checked in with Ms. Cruz, she said she had “kind of ghosted” Dr. Glandt due to her work and school constraints, but she hadn’t abandoned the diet. She appreciated, too, that Dr. Glandt had not given up on her and kept calling and messaging. “She’s not at all like a typical doctor who would just tell me to lose weight and shake their head at me,” Ms. Cruz said. 

Because Dr. Glandt’s approach is time-intensive and high-touch, it might seem impractical to scale up, but Dr. Glandt’s app uses artificial intelligence to help with communications thus allowing her, with help from part-time health coaches, to care for patients. 

This early success in one of the United States’ poorest and sickest neighborhoods should give us hope that type 2 diabetes need not to be a progressive irreversible disease, even among the disadvantaged. 

OwnaHealth’s track record, along with that of Virta and other similar low-carbohydrate medical practices also give hope to the food-is-medicine idea. Diabetes can go into remission, and people can be healed, provided that health practitioners prescribe the right foods. And in truth, it’s not a diet. It’s a way of eating that must be maintained. The sustainability of low-carbohydrate diets has been a point of contention, but the Virta trial, with 38% of patients sustaining remission at 2 years, showed that it’s possible. (OwnaHealth, for its part, offers long-term maintenance plans to help patients stay very low-carb permanently.) 

Given the tremendous costs and health burden of diabetes, this approach should no doubt be the first line of treatment for doctors and the ADA. The past two decades of clinical trial research have demonstrated that remission of type 2 diabetes is possible through diet alone. It turns out that for metabolic diseases, only certain foods are truly medicine.

One month earlier, Dr. Glandt’s company, OwnaHealth, was contracted by Essen to conduct a 100-person pilot program for endocrinology patients. Essen is the largest Medicaid provider in New York City, and “they were desperate for an endocrinologist,” said Dr. Glandt, who trained at Columbia University in New York. So she came — all the way from Madrid, Spain. She commutes monthly, staying for a week each visit.

Dr. Glandt keeps up this punishing schedule because, as she explains, “it’s such a high for me to see these incredible transformations.” Her mostly Black and Hispanic patients are poor and lack resources, yet they lose significant amounts of weight, and their health issues resolve.

“Food is medicine” is an idea very much in vogue. The concept was central to the landmark White House Conference on Hunger, Nutrition, and Health in 2022 and is now the focus of a number of a wide range of government programs. Recently, the Senate held a hearing aimed at further expanding food as medicine programs.

Still, only a single randomized controlled clinical trial has been conducted on this nutritional approach, with unexpectedly disappointing results. In the mid-Atlantic region, 456 food-insecure adults with type 2 diabetes were randomly assigned to usual care or the provision of weekly groceries for their entire families for about 1 year. Provisions for a Mediterranean-style diet included whole grains, fruits and vegetables, lean protein, low-fat dairy products, cereal, brown rice, and bread. In addition, participants received dietary consultations. Yet, those who got free food and coaching did not see improvements in their average blood sugar (the study’s primary outcome), and their low-density lipoprotein (LDL) cholesterol and high-density lipoprotein (HDL) cholesterol levels appeared to have worsened. 

“To be honest, I was surprised,” the study’s lead author, Joseph Doyle, PhD, professor at the Sloan School of Management at MIT in Cambridge, Massachusetts, told me. “I was hoping we would show improved outcomes, but the way to make progress is to do well-randomized trials to find out what works.”

I was not surprised by these results because a recent rigorous systematic review and meta-analysis in The BMJ did not show a Mediterranean-style diet to be the most effective for glycemic control. And Ms. Efem was not in fact following a Mediterranean-style diet.

Ms. Efem’s low-carb success story is anecdotal, but Dr. Glandt has an established track record from her 9 years’ experience as the medical director of the eponymous diabetes center she founded in Tel Aviv. A recent audit of 344 patients from the center found that after 6 months of following a very low–carbohydrate diet, 96.3% of those with diabetes saw their A1c fall from a median 7.6% to 6.3%. Weight loss was significant, with a median drop of 6.5 kg (14 pounds) for patients with diabetes and 5.7 kg for those with prediabetes. The diet comprises 5%-10% of calories from carbs, but Dr. Glandt does not use numeric targets with her patients.

Blood pressure, triglycerides, and liver enzymes also improved. And though LDL cholesterol went up by 8%, this result may have been offset by an accompanying 13% rise in HDL cholesterol. Of the 78 patients initially on insulin, 62 were able to stop this medication entirely.

Although these results aren’t from a clinical trial, they’re still highly meaningful because the current dietary standard of care for type 2 diabetes can only slow the progression of the disease, not cause remission. Indeed, the idea that type 2 diabetes could be put into remission was not seriously considered by the American Diabetes Association (ADA) until 2009. By 2019, an ADA report concluded that “[r]educing overall carbohydrate intake for individuals with diabetes has demonstrated the most evidence for improving glycemia.” In other words, the best way to improve the key factor in diabetes is to reduce total carbohydrates. Yet, the ADA still advocates filling one quarter of one’s plate with carbohydrate-based foods, an amount that will prevent remission. Given that the ADA’s vision statement is “a life free of diabetes,” it seems negligent not to tell people with a deadly condition that they can reverse this diagnosis. 

A 2023 meta-analysis of 42 controlled clinical trials on 4809 patients showed that a very low–carbohydrate ketogenic diet (keto) was “superior” to alternatives for glycemic control. A more recent review of 11 clinical trials found that this diet was equal but not superior to other nutritional approaches in terms of blood sugar control, but this review also concluded that keto led to greater increases in HDL cholesterol and lower triglycerides. 

Dr. Glandt’s patients in the Bronx might not seem like obvious low-carb candidates. The diet is considered expensive and difficult to sustain. My interviews with a half dozen patients revealed some of these difficulties, but even for a woman living in a homeless shelter, the obstacles are not insurmountable.

Jerrilyn, who preferred that I use only her first name, lives in a shelter in Queens. While we strolled through a nearby park, she told me about her desire to lose weight and recover from polycystic ovary syndrome, which terrified her because it had caused dramatic hair loss. When she landed in Dr. Glandt’s office at age 28, she weighed 180 pounds. 

Less than 5 months later, Jerrilyn had lost 25 pounds, and her period had returned with some regularity. She said she used “food stamps,” known as the Supplemental Nutrition Assistance Program (SNAP), to buy most of her food at local delis because the meals served at the shelter were too heavy in starches. She starts her day with eggs, turkey bacon, and avocado. 

“It was hard to give up carbohydrates because in my culture [Latina], we have nothing but carbs: rice, potatoes, yuca,” Jerrilyn shared. She noticed that carbs make her hungrier, but after 3 days of going low-carb, her cravings diminished. “It was like getting over an addiction,” she said.

Jerrilyn told me she’d seen many doctors but none as involved as Dr. Glandt. “It feels awesome to know that I have a lot of really useful information coming from her all the time.” The OwnaHealth app tracks weight, blood pressure, blood sugar, ketones, meals, mood, and cravings. Patients wear continuous glucose monitors and enter other information manually. Ketone bodies are used to measure dietary adherence and are obtained through finger pricks and test strips provided by OwnaHealth. Dr. Glandt gives patients her own food plan, along with free visual guides to low-carbohydrate foods by dietdoctor.com. 

Dr. Glandt also sends her patients for regular blood work. She says she does not frequently see a rise in LDL cholesterol, which can sometimes occur on a low-carbohydrate diet. This effect is most common among people who are lean and fit. She says she doesn’t discontinue statins unless cholesterol levels improve significantly.

Samuel Gonzalez, age 56, weighed 275 pounds when he walked into Dr. Glandt’s office this past November. His A1c was 9.2%, but none of his previous doctors had diagnosed him with diabetes. “I was like a walking bag of sugar!” he joked. 

A low-carbohydrate diet seemed absurd to a Puerto Rican like himself: “Having coffee without sugar? That’s like sacrilegious in my culture!” exclaimed Mr. Gonzalez. Still, he managed, with SNAP, to cook eggs and bacon for breakfast and some kind of protein for dinner. He keeps lunch light, “like tuna fish,” and finds checking in with the OwnaHealth app to be very helpful. “Every day, I’m on it,” he said. In the past 7 months, he’s lost 50 pounds, normalized his cholesterol and blood pressure levels, and lowered his A1c to 5.5%.

Mr. Gonzalez gets disability payments due to a back injury, and Ms. Efem receives government payments because her husband died serving in the military. Ms. Efem says her new diet challenges her budget, but Mr. Gonzalez says he manages easily.

Mélissa Cruz, a 28-year-old studying to be a nail technician while also doing back office work at a physical therapy practice, says she’s stretched thin. “I end up sad because I can’t put energy into looking up recipes and cooking for me and my boyfriend,” she told me. She’ll often cook rice and plantains for him and meat for herself, but “it’s frustrating when I’m low on funds and can’t figure out what to eat.” 

Low-carbohydrate diets have a reputation for being expensive because people often start eating pricier foods, like meat and cheese, to replace cheaper starchy foods such as pasta and rice. Eggs and ground beef are less expensive low-carb meal options, and meat, unlike fruits and vegetables, is easy to freeze and doesn’t spoil quickly. These advantages can add up.

A 2019 cost analysis published in Nutrition & Dietetics compared a low-carbohydrate dietary pattern with the New Zealand government’s recommended guidelines (which are almost identical to those in the United States) and found that it cost only an extra $1.27 in US dollars per person per day. One explanation is that protein and fat are more satiating than carbohydrates, so people who mostly consume these macronutrients often cut back on snacks like packaged chips, crackers, and even fruits. Also, those on a ketogenic diet usually cut down on medications, so the additional $1.27 daily is likely offset by reduced spending at the pharmacy.

It’s not just Bronx residents with low socioeconomic status (SES) who adapt well to low-carbohydrate diets. Among Alabama state employees with diabetes enrolled in a low-carbohydrate dietary program provided by a company called Virta, the low SES population had the best outcomes. Virta also published survey data in 2023 showing that participants in a program with the Veteran’s Administration did not find additional costs to be an obstacle to dietary adherence. In fact, some participants saw cost reductions due to decreased spending on processed snacks and fast foods.

Ms. Cruz told me she struggles financially, yet she’s still lost nearly 30 pounds in 5 months, and her A1c went from 7.1% down to 5.9%, putting her diabetes into remission. Equally motivating for her are the improvements she’s seen in other hormonal issues. Since childhood, she’s had acanthosis, a condition that causes the skin to darken in velvety patches, and more recently, she developed severe hirsutism to the point of growing sideburns. “I had tried going vegan and fasting, but these just weren’t sustainable for me, and I was so overwhelmed with counting calories all the time.” Now, on a low-carbohydrate diet, which doesn’t require calorie counting, she’s finally seeing both these conditions improve significantly.

When I last checked in with Ms. Cruz, she said she had “kind of ghosted” Dr. Glandt due to her work and school constraints, but she hadn’t abandoned the diet. She appreciated, too, that Dr. Glandt had not given up on her and kept calling and messaging. “She’s not at all like a typical doctor who would just tell me to lose weight and shake their head at me,” Ms. Cruz said. 

Because Dr. Glandt’s approach is time-intensive and high-touch, it might seem impractical to scale up, but Dr. Glandt’s app uses artificial intelligence to help with communications thus allowing her, with help from part-time health coaches, to care for patients. 

This early success in one of the United States’ poorest and sickest neighborhoods should give us hope that type 2 diabetes need not to be a progressive irreversible disease, even among the disadvantaged. 

OwnaHealth’s track record, along with that of Virta and other similar low-carbohydrate medical practices also give hope to the food-is-medicine idea. Diabetes can go into remission, and people can be healed, provided that health practitioners prescribe the right foods. And in truth, it’s not a diet. It’s a way of eating that must be maintained. The sustainability of low-carbohydrate diets has been a point of contention, but the Virta trial, with 38% of patients sustaining remission at 2 years, showed that it’s possible. (OwnaHealth, for its part, offers long-term maintenance plans to help patients stay very low-carb permanently.) 

Given the tremendous costs and health burden of diabetes, this approach should no doubt be the first line of treatment for doctors and the ADA. The past two decades of clinical trial research have demonstrated that remission of type 2 diabetes is possible through diet alone. It turns out that for metabolic diseases, only certain foods are truly medicine.

For 3 years, Ajala Efem’s type 2 diabetes was so poorly controlled that her blood sugar often soared northward of 500 mg/dL despite insulin shots three to five times a day. She would experience dizziness, vomiting, severe headaches, and the neuropathy in her feet made walking painful. She was also — literally — frothing at the mouth. The 47-year-old single mother of two adult children with mental disabilities feared that she would die.

Ms. Efem lives in the South Bronx, which is among the poorest areas of New York City, where the combined rate of prediabetes and diabetes is close to 30%, the highest rate of any borough in the city.

She had to wait 8 months for an appointment with an endocrinologist, but that visit proved to be life-changing. She lost 28 pounds and got off 15 medications in a single month. She did not join a gym or count calories; she simply changed the food she ate and adopted a low-carb diet.

“I went from being sick to feeling so great,” she told her endocrinologist recently: “My feet aren’t hurting; I’m not in pain; I’m eating as much as I want, and I really enjoy my food so much.” 

Ms. Efem’s life-changing visit was with Mariela Glandt, MD, at the offices of Essen Health Care.
