Three billion dollars: It’s enough to finance the annual out-of-pocket costs for 1 in 7 patients with cancer. It would cover almost half of the National Cancer Institute’s annual budget. And it could fund President Biden’s entire Cancer Moonshot program, with more than a billion to spare.

It’s also how much the United States spends on unused cancer drugs each year, some experts estimate.

Every year in the United States, hospitals and practices discard substantial quantities of expensive oncology drugs.

The reason boils down to inefficient drug packaging. Drug companies typically sell infused drugs in one or two single-dose vial sizes, but patients don’t come in such neat packages. A patient may need 300 mg of a drug that is only sold as 200 mg vials, which means half of a vial will go to waste.

Although most oncology drugs don’t incur substantial waste, even small volumes can translate to millions of dollars a year.

But can this money be saved or reallocated, if only we delivered drugs more efficiently?

Some experts don’t believe that’s possible.

“Attempts to recoup money for discarded drugs wouldn’t happen in a vacuum,” said Robin Yabroff, PhD, MBA, an epidemiologist and scientific vice president of Health Services Research at the American Cancer Society, who was part of a committee commissioned to evaluate the costs associated with discarded drugs.

The potential catch of any widespread effort to seek repayment or reduce the amount of discarded drugs, Dr. Yabroff and colleagues note, is that manufacturers would “simply increase the price of the vial.”

In other words, attempting to fix one problem may lead to another — essentially a whack-a-mole of cancer costs, which are projected to balloon to $246 billion by 2030.  

What this means is without sweeping policies to rein in cancer care costs, oncologists can only do so much. And every little bit counts.

“We are left chipping away at this monster of cancer care costs,” said Adam Binder, MD, a medical oncologist at the Sidney Kimmel Cancer Center at Jefferson Health in Philadelphia.
 

Millions spent on “reasonable amount” of waste

Michal Sarfaty, MD, was excited when enfortumab vedotin came on the market to treat advanced urothelial cancer in late 2019.

The cost of the drug, however, tempered her enthusiasm.

Enfortumab vedotin is a “great drug,” said Dr. Sarfaty, an oncologist at the Sheba Medical Center, Ramat Gan, Israel. But it can cost upwards of $500,000 a year for an average-weight man.

Given the expense, Dr. Sarfaty wanted to understand how much of the drug gets thrown away. During a fellowship at Memorial Sloan Kettering (MSK) Cancer Center in New York, Dr. Sarfaty explored the amount of unused enfortumab vedotin among the 64 patients who received the drug in 2020. She, along with a team at MSK, calculated the price tag of that waste and extrapolated those estimates for patients across the country.

Although waste occurred in almost half of administered doses (367 of 793), only a small volume got discarded — 2.9% per dose, on average.

Multiplying unused milligrams by the cost per milligram, Dr. Sarfaty and colleagues estimated that, for each patient, $3,127 of the drug got discarded. When calculated over the year, the cost came to just over $200,000 at MSK, and nearly $15 million when projected across the approved patient population in the United States.

“Ultimately, we did not see a lot of waste with this specific drug,” Dr. Sarfaty said. “Under 2.9% is considered a reasonable amount, below the 3% threshold Peter Bach, MD, and colleagues recommend. But even with this small amount of waste, the cost per patient and to the system remains notable.”
 

The problem with recouping drug waste

Estimates from the Centers for Medicare & Medicaid Services (CMS), which tracks costs associated with discarded weight-based drugs covered under Medicare Part B, support the notion that small quantities of discarded drugs can still translate to big bucks.

Since 2017, CMS has required healthcare providers to report the volume of drugs discarded from a single-dose vial using a code, known as the JW modifier. The JW modifier means that providers can be reimbursed for the entire vial amount, not just the quantity the patient used.

In 2019, claims data from Medicare Part B showed that 1.85% of discarded rituximab came to $33.3 million. For infliximab, the 1.55% of discarded liquid translated to $15 million, and just 0.36% of discarded pembrolizumab reached $10 million.

However, experts question whether the JW modifier accurately reflects the quantity of drugs discarded.

According to the 2021 report from the National Academies of Sciences, Engineering, and Medicine (NASEM), most physicians don’t use the JW modifier. Among Medicare claims, 16.2% included the JW modifier in 2017 and 16.9% did in 2018.

The rate was significantly lower for private insurance. Of more than 4 million private insurance claims on 77 drugs made in 2017 and 2018, only 3.6% included the JW modifier; 15 of these drugs had no JW claims.

“Although we found that most physicians don’t use the JW modifier, even those who do, don’t use it consistently, even for the same patient,” said Dr. Yabroff, a co-author on the report.

Going a step further, Dr. Yabroff and colleagues argue that even if everyone used the JW modifier as intended, manufacturers would probably increase the price of drugs to compensate for any loss, potentially eliminating savings for payers.

That’s because, in the United States, manufacturers typically base drug prices on a patient and payers’ “willingness to pay for better health,” not on the volume of liquid used. Take a patient who pays $2,000 to receive the dose they need. If that dose is 600 mg but requires using two vials of 400 mg, then “to the patient, the 600-mg dose is worth $2,000, and the remainder has no value whatsoever,” the NASEM authors argue.

The authors parallel this scenario to purchasing a designer coat or dress. If that item requires alterations that remove a section of material, “the customer does not typically get a rebate because all the fabric was not needed,” the NASEM team writes.

But there’s a flaw in this rationale, argues Daniel Goldstein, MD, a medical oncologist at the Rabin Medical Center, Petah Tikva, Israel. A person’s willingness to pay for better health assumes that the price of a drug is based on proper market forces, where a drug’s cost and its effectiveness are in harmony.

“The problem is we’re operating in a broken market where the prices of oncology drugs have no real bearing on their efficacy,” said Dr. Goldstein.

And, as Dr. Bach noted in a 2021 Health Affairs piece, willingness to pay also requires that consumers know what they’re paying and allows them to walk away from an excessively high price.

But neither is a reality.

For one, Dr. Bach explains, companies may lowball the monthly price of a drug. In 2020, GlaxoSmithKline (GSK) announced that its new drug Blenrep would carry a list price of $8,277 per vial, or about $23,900 per month for an average 79 kg (175 lb) patient. That price accounts for two vials of the drug. But, according to Dr. Bach, “what GSK left out is that 44% of U.S. adults weigh more than 80 kg, and above that weight, three vials are needed per dose.” That would raise the average monthly cost to $30,479.

Perhaps more importantly, consumers can’t easily walk away.

“Medicare can’t negotiate prices and is forced to pay what a drug company says,” Dr. Goldstein said. “This is very different to when I buy a coat. If the price is too high, I can walk away.”
 

Fixed dosing: A solution or a new problem?

Efforts to reduce the financial impact of discarded cancer drugs can blow back on physicians, patients, and payers in other unanticipated ways. Take fixed dosing. Although chemotherapy dosing remains weight-based, many targeted therapies — such as nivolumab and pembrolizumab — recently transitioned to a fixed dosing regimen.

Administering a fixed, instead of weight-based, dose eliminates waste but can create new problems.

“Patients with cancer not only tend to get too high a dose of the drug, but costs go up significantly,” said Dr. Goldstein. In a 2017 analysis, Dr. Goldstein and colleagues compared dosing strategies in patients with metastatic non–small cell lung cancer who received pembrolizumab. The team found that the total annual cost of weight-based dosing was $2.6 billion, whereas the cost of the fixed dosing strategy was $3.44 billion — 24% more. In other words, personalized weight-based dosing would save more than $825 million dollars in the United States each year.

A 2020 analysis based in France found a similar cost increase of 26% for fixed dosing of pembrolizumab as well as nivolumab.

“I’ve argued we should go back to weight-based dosing,” Dr. Goldstein said. “Why should we give a higher dose with the same efficacy when that dose will cost significantly more and has the potential to increase adverse events?”
 

Does dose rounding work?

Rose DiMarco, PharmD, BCPS, BCOP, keeps a tight watch on patients being treated at the Sidney Kimmel Cancer Center at Jefferson Health in Philadelphia.

Dr. DiMarco educates patients about their treatment plan, reviews their lab results, and monitors them for side effects and drug interactions.

She also thinks a lot about costs.

“We spend about $100,000 a day on oncology drugs, and we want to make sure we’re not being wasteful,” Dr. DiMarco said in an interview.

One major initiative to curb waste and reduce costs at Jefferson has centered on dose rounding, which calculates whether a specific dose can be altered slightly to conserve vials and prevent waste. According to the Hematology/Oncology Pharmacy Association, a patient can receive up to 10% more or less of a weight-based dose without impacting treatment efficacy.

If, for instance, a patient requires 380 mg, but two vials come to 400 mg, rounding up that dose by approximately 5% means eliminating 20 mg that would go unused. But if that patient requires 420 mg, rounding down about 5% means substantial savings from not opening a new vial.

At Jefferson, Dr. DiMarco and her pharmacy colleagues map out dose ranges for all patients. Anyone who falls inside the 10% may be eligible for dose rounding. Anyone who doesn’t will receive the usual dose.

Although it is a challenge to implement, dose rounding has become standard of care at many cancer centers across the United States and is linked to substantial savings.

A 2018 analysis projected annual savings of $865,000 associated with rounding down eight monoclonal antibodies for patients with metastatic disease at a community cancer center. A more recent analysis from the Mayo Clinic found that dose rounding saved a total of 9,814 drug vials — 4485 of which were cancer drugs and 5329 of which were biologics — and resulted in $7.3 million in savings over 6 months in 2019 — $1.56 million from oncology agents and $5.7 from biologics.

And in a small 2019 analysis, researchers at Jefferson showed dose rounding of one monoclonal antibody saved approximately $30,000 in just 3 months, Dr. DiMarco noted.

“Not only does this process reduce costs and waste, but it also standardizes the preparation of hazardous medications, which can help prevent medication errors,” Dr. DiMarco said.
 

Nibbling around the edges

Despite estimates that scale into the billions of dollars, “drug wastage is just a small part of overall cancer costs,” Dr. Sarfaty said.

Fumiko Chino, MD, a radiation oncologist at MSK, agrees. “When we talk about affordability and cost, we can nibble around the edges of what’s really important,” Dr. Chino said. “Discarded drugs may cost a lot when you consider them in aggregate, but they are not as important as negotiated drug prices, which could substantially reduce overall costs.”

And until drug prices are addressed on a broader policy level, the cost of cancer care likely won’t improve in a meaningful way.

“But for the patient sitting in front of me, my focus will always be to provide the best care possible,” Dr. Binder said.

Rose DiMarco, PharmD, BCPS, BCOP, keeps a tight watch on patients being treated at the Sidney Kimmel Cancer Center at Jefferson Health in Philadelphia.

Dr. DiMarco educates patients about their treatment plan, reviews their lab results, and monitors them for side effects and drug interactions.

She also thinks a lot about costs.

“We spend about $100,000 a day on oncology drugs, and we want to make sure we’re not being wasteful,” Dr. DiMarco said in an interview.

One major initiative to curb waste and reduce costs at Jefferson has centered on dose rounding, which calculates whether a specific dose can be altered slightly to conserve vials and prevent waste. According to the Hematology/Oncology Pharmacy Association, a patient can receive up to 10% more or less of a weight-based dose without impacting treatment efficacy.

If, for instance, a patient requires 380 mg, but two vials come to 400 mg, rounding up that dose by approximately 5% means eliminating 20 mg that would go unused. But if that patient requires 420 mg, rounding down about 5% means substantial savings from not opening a new vial.

At Jefferson, Dr. DiMarco and her pharmacy colleagues map out dose ranges for all patients. Anyone who falls inside the 10% may be eligible for dose rounding. Anyone who doesn’t will receive the usual dose.

Although it is a challenge to implement, dose rounding has become standard of care at many cancer centers across the United States and is linked to substantial savings.

A 2018 analysis projected annual savings of $865,000 associated with rounding down eight monoclonal antibodies for patients with metastatic disease at a community cancer center. A more recent analysis from the Mayo Clinic found that dose rounding saved a total of 9,814 drug vials — 4485 of which were cancer drugs and 5329 of which were biologics — and resulted in $7.3 million in savings over 6 months in 2019 — $1.56 million from oncology agents and $5.7 from biologics.

And in a small 2019 analysis, researchers at Jefferson showed dose rounding of one monoclonal antibody saved approximately $30,000 in just 3 months, Dr. DiMarco noted.

“Not only does this process reduce costs and waste, but it also standardizes the preparation of hazardous medications, which can help prevent medication errors,” Dr. DiMarco said.
 

Nibbling around the edges

Despite estimates that scale into the billions of dollars, “drug wastage is just a small part of overall cancer costs,” Dr. Sarfaty said.

Fumiko Chino, MD, a radiation oncologist at MSK, agrees. “When we talk about affordability and cost, we can nibble around the edges of what’s really important,” Dr. Chino said. “Discarded drugs may cost a lot when you consider them in aggregate, but they are not as important as negotiated drug prices, which could substantially reduce overall costs.”

And until drug prices are addressed on a broader policy level, the cost of cancer care likely won’t improve in a meaningful way.

“But for the patient sitting in front of me, my focus will always be to provide the best care possible,” Dr. Binder said.

I used to attend the Supportive Care in Oncology Symposium every year, but to my dismay, the American Society for Clinical Oncology stopped hosting the symposium a few years ago. Instead, ASCO now incorporates palliative care research fully into its annual meeting which was held in early June in Chicago. Being integrated into the annual meeting means greater exposure to a broader audience that may not otherwise see this work. In this column, I highlight some presentations that stood out to me.
 

Palliative care studies for patients with hematologic malignancies

There continues to be low uptake of outpatient palliative care services among patients with hematologic malignancies. Fortunately, there are efforts underway to study the impact of integrating early palliative care into the routine care of hematology patients. In a study presented by Mazie Tsang, MD, a clinical fellow at the University of California, San Francisco, researchers embedded a palliative care nurse practitioner in a hematology clinic and studied the impact this single NP had over 4 years of integration. They found that patients were less likely to be hospitalized or visit the emergency department after integrating the NP. They also found that advance directives were more likely to be completed following NP integration. The results were limited by small sample size and lack of a true control group, but generally trended toward significance when compared with historical controls.

Other studies highlighted the relatively high symptom burden among patients with hematologic malignancies, such as myeloma, leukemia, and lymphoma. In a study presented by Sarah E. Monick, MD, of the University of Chicago, researchers found that, among adolescents and young adults with hematologic malignancies seen in a clinic where a palliative care provider was embedded, symptom burden was high across the board regardless of where patients were in their disease trajectory or their demographic characteristics. Due to the presence of high symptom burden among adolescents and young adults, the authors suggest that patients undergo screening at every visit and that supportive care be incorporated throughout the patient’s journey.

Kyle Fitzgibbon of the Princess Margaret Cancer Centre in Toronto shared details of an ongoing multicenter, randomized, controlled, phase 3 trial designed to evaluate the effect of a novel psychosocial/palliative care intervention for patients with acute leukemia hospitalized for induction chemotherapy. The intervention will consist of 8 weeks of psychological support as well as access to palliative care for physical symptoms. Participants will be randomized to receive either intervention or standard of care at the beginning of their hospitalization. Researchers plan to study the impact of the intervention on physical and psychological symptom severity, quality of life, and patient satisfaction at multiple time points. It will be exciting to see the results of this study given that there are very few research clinical trials examining early palliative care with patients who have hematologic malignancies.

Trends in palliative care integration with oncology care

One key trend that I am elated to see is the integration of palliative care throughout the entire patient journey. A secondary analysis of oncology practice data from the National Cancer Institute Community Oncology Research Program found that more than three-quarters of outpatient oncology practices surveyed in 2015 have integrated palliative care inpatient and outpatient services. 36% said they had an outpatient palliative care clinic. More availability of services typically translates to better access to care and improved outcomes for patients, so it is always nice to see these quality metrics continue to move in a positive direction. The analysis was presented by Tiffany M. Statler, PA, of Atrium Health Wake Forest Baptist, Winston Salem, N.C.

It turns out that patients are also advocating for integrated palliative care. A unique qualitative project brought together patient advocates from several countries to hold a moderated discussion about quality of life and treatment side effects. The advocates focused on the importance of maintaining independence with activities of daily living as a significant quality of life goal, particularly as treatments tend to cause cumulative mental and physical fatigue. They highlighted the importance of palliative care for helping achieve quality of life goals, especially in latter part of the disease trajectory. The project was presented by Paul Wheatley-Price, MD, of the Ottawa Hospital Cancer Centre, University of Ottawa.

In 2010, a study by Temel and colleagues was published, finding that patients with metastatic non–small cell lung cancer who received palliative care early had significant improvements in quality of life and mood as compared with patients who received standard care. It was a landmark study and is frequently cited. The Temel group reports on the planning process for a new randomized controlled trial of palliative care with metastatic lung cancer patients who have targetable mutations. With next generation sequencing of tumor tissue, many patients with metastatic lung cancer are identified at diagnosis as having a targetable mutation. As such, they may receive a targeted therapy as first-line treatment instead of traditional chemotherapy. This has lengthened survival considerably, but the disease remains incurable and ultimately fatal, and the trajectory can resemble a roller-coaster ride.

In this new randomized controlled trial, patients in the experimental arm will receive four monthly visits with a palliative care clinician who is specially trained to help patients manage the uncertainties of prolonged illness. The researchers plan to evaluate patients’ distress levels and prognostic awareness, as well as evidence of advance care planning in the chart.

And, a study presented by Roberto Enrique Ochoa Planchart, MD, of Chen Medical Centers, Miami, found that when primary care providers used declines in functional status as a trigger for referring advanced cancer patients to palliative care, those patients were less likely to be admitted to the hospital near the end of life, translating to an 86% cost savings. This study reiterated the importance of partnering with a patient’s nononcologic providers, that is, primary care and palliative care clinicians to improve outcomes at the end of life.

Use of technology in palliative care

Numerous studies were reported on innovative uses of technology for various functions relevant to palliative care. They included everything from capturing patient-reported outcomes through patient-facing smartphone apps, to using artificial intelligence and/or machine learning to build prognostication tools and to generate earlier referrals to palliative care. There were presentations on the use of online tools to assist with and document goals of care conversations.

As a clinician who is always looking for new ways to capture patient symptom information and motivate patients to engage in advance care planning, I am excited about the prospect of using some of these tools in real time.

Over the past decade, the U.S. Food and Drug Administration has approved new cancer drugs twice as fast as the European Medicines Agency (EMA), often using accelerated pathways, a new analysis shows.

Between 2010 and 2019, the FDA approved almost all oncology therapies ahead of the EMA. Drugs entered the United States market about 8 months (241 days) before European market authorization.

But do quicker review times translate to wins for patients?

“The faster FDA approval process potentially provides earlier access to potentially life-prolonging medications for patients with cancer in the United States,” Ali Raza Khaki, MD, department of oncology, Stanford (Calif.) University School of Medicine, told this news organization. “On the surface, this is a good thing. However, it comes with limitations.”

Earlier drug approval often means greater uncertainty about an agent’s benefit – most notably, whether it will improve a patient’s survival or quality of life. Dr. Khaki pointed to a study published in JAMA Internal Medicine, which found that only 19 of 93 (20%) cancer drugs that had been recently approved through the FDA’s accelerated approval pathway demonstrated an improvement in overall survival.

In the new study, published online in JAMA Network Open, Dr. Khaki and colleagues found that among the 89 cancer drugs approved in the United States and Europe between January 2010 and December 2019, the FDA approved 85 (95%) before European authorization and four (5%) after.

The researchers found that the median FDA review time was half that of the EMA’s (200 vs. 426 days). Furthermore, 64 new drug applications (72%) were submitted to the FDA first, compared with 21 (23%) to the EMA.

Of the drugs approved through an accelerated pathway, three were ultimately pulled from the U.S. market, compared with one in Europe.

“These early drug approvals that later lead to withdrawal expose many more patients to toxicity, including financial toxicity, given the high cost of cancer medications,” Dr. Khaki commented.

In addition, 35 oncology therapies (39%) were approved by the FDA before trial results were published, compared with only eight (9%) by the EMA. Although FDA drug labels contain some information about efficacy and toxicity, scientific publications often have much more, including details about study populations and toxicities.

“Without this information, providers may be limited in their knowledge about patient selection, clinical benefit, and optimal toxicity management,” Dr. Khaki said.

Jeff Allen PhD, president and CEO of the nonprofit Friends of Cancer Research, who wasn’t involved in the study, believes that an FDA approval before publication shouldn’t be “particularly concerning.”

“Peer-reviewed publication is an important component of validating and communicating scientific findings, but the processes and time lines for individual journals can be highly variable,” he said. “I don’t think we would want to see a situation where potential beneficial treatments are held up due to unrelated publication processes.”

The author of an invited commentary in JAMA Network Open had a different take on the study findings.

“A tempting interpretation” of this study is that the FDA is a “superior agency for expedited review times that bring cancer drugs to patients earlier,” Kristina Jenei, BSN, MSc, with the University of British Columbia School of Population and Public Health, writes. In addition, the fact that more drugs were pulled from the market after approval in the United States than in Europe could be interpreted to mean that the system is working as it should.

Although the speed of FDA reviews and the number of subsequent approvals have increased over time, the proportion of cancer drugs that improve survival has declined. In addition, because the FDA’s follow-up of postmarketing studies has been “inconsistent,” a substantial number of cancer drugs that were approved through accelerated pathways have remained on the market for years without confirmation of their benefit.

Although regulatory agencies must balance earlier patient access to novel treatments with evidence that the therapies are effective and safe, “faster review times and approvals are not cause for celebration; better patient outcomes are,” Ms. Jenei writes. “In other words, quality over quantity.”

The study was supported by the National Cancer Institute. Dr. Khaki reported stock ownership from Merck and stock ownership from Sanofi outside the submitted work. Dr. Allen and Ms. Jenei have disclosed no relevant financial relationships.

Although breast cancer occurs less frequently in Black women, compared with White women, they have a much higher risk of dying from the disease.

In the United States, age-adjusted breast cancer mortality between 2014 and 2018 was approximately 40% higher among Black women than among non-Hispanic White women.

This mortality gap likely reflects the fact that Black women face substantial barriers to obtaining timely, high-quality medical care, compared with White women, lead author Ismail Jatoi, MD, PhD, University of Texas Health Science Center, San Antonio, and colleagues suggest in a recent opinion piece.

The article was published online  in The New England Journal of Medicine.

When the team examined the statistics for breast cancer mortality, they found a surprise: The mortality gap between races only dates back to 1980.

Prior to 1980, mortality from breast cancer among Black women was slightly lower than White women, Dr. Jatoi and colleagues point out.

That year was a turning point in breast cancer management, as in 1980, both mammography screening and adjuvant endocrine therapy became available.

This was also when the mortality gap between the races started to show up.

It was disparities in access to the two new interventions that precipitated the divergence, as the authors suggest. Why this occurred is fairly self-evident, they comment.

“Black women are more likely than White women to lack health insurance or to have inadequate coverage, which has limited their access to mammography screening and adversely affected therapeutic decisionmaking,” researchers point out.

Moreover, both mammography screening and endocrine therapy primarily benefit patients with hormone receptor (HR)-positive breast cancer, which is equally common in Black and White patients. However, Black women have a 65% higher rate of HR-negative cancers than White women – and HR-negative tumors are often detected during the interval between mammography screening exams as palpable cancers.

Black women also have an 81% higher rate of triple-negative breast cancer, so they have benefited less from mammography screening and adjuvant endocrine therapy, both of which favor the detection and treatment of HR-positive breast cancer, the authors emphasize.

Some have suggested that the excess HR-negative breast cancer in Black women might be explained by hereditary factors. Yet as Dr. Jatoi and colleagues point out, the incidence of HR-negative breast cancer has actually been falling across all races in the United States since 1992.

However, the declines have been slower among Black women, and reductions in its incidence have been smaller among White women living in less affluent regions of the United States compared with White women from more affluent regions.

These patterns suggest that social determinants of health influence not only access to and quality of health care but also the development of HR-negative breast cancers, as the authors observe.

“If all people with breast cancer benefited equally from effective medical interventions, racial differences in mortality for individual tumor subtypes would largely reflect differences in incidence,” Dr. Jatoi and colleagues continue.

Yet the statistics show that the substantial racial disparities in mortality for both HR-positive and HR-negative cancers between Black and White women cannot be explained by differences in the incidence of either tumor alone, they write.

For example, mortality for HR-positive breast cancer is 19% higher among Black women than among White women, yet the incidence of HR-positive breast cancer is 22% lower among Black women.

Similarly, mortality from HR-negative breast cancer is over twice as high among Black women as it is among White women – a substantially larger disparity, compared with the 65% relative difference in the incidence of HR-negative breast cancer between the two races.

“Universal health care coverage could reduce disparities in treatment for cancers of all subtypes, including triple-negative breast cancer,” Dr. Jatoi and colleagues emphasize.

“Ensuring universal access to high-quality medical care can substantially narrow the racial disparity in U.S. breast-cancer mortality,” they conclude. 

The authors have reported no relevant financial relationships.

Although breast cancer occurs less frequently in Black women, compared with White women, they have a much higher risk of dying from the disease.

In the United States, age-adjusted breast cancer mortality between 2014 and 2018 was approximately 40% higher among Black women than among non-Hispanic White women.

This mortality gap likely reflects the fact that Black women face substantial barriers to obtaining timely, high-quality medical care, compared with White women, lead author Ismail Jatoi, MD, PhD, University of Texas Health Science Center, San Antonio, and colleagues suggest in a recent opinion piece.

When the team examined the statistics for breast cancer mortality, they found a surprise: The mortality gap between races only dates back to 1980.

A study of elderly patients with HER2-positive/HR-negative metastatic breast cancer finds a significantly shorter median overall survival in actual clinical practice than younger counterparts.

After 46 months of treatment, the survival rate was only 25%, according to a study presented in June at the annual meeting of the American Society of Clinical Oncology. The finding suggests that older age is an important prognostic factor for breast cancer survival, said study author Zhonghui Jenny Ou, a doctoral candidate at the Massachusetts College of Pharmacy and Health Sciences in Boston.

For comparison, Ms. Ou cited the CLEOPATRA trial which showed a median overall survival of 57.1 months for patients who were treated with pertuzumab, docetaxel and trastuzumab versus 40.8 months for placebo with docetaxel plus trastuzumab.

The Ou study is based on an analysis of data between 2012 and 2016 from the SEER-Medicare database. The final analysis included 73 women (average age 75 years at diagnosis) with early-stage HER2-positive/HR-negative metastatic breast cancer. Fifty-six women were treated with trastuzumab with pertuzumab and chemotherapy as first-line treatment, and 17 were treated with chemotherapy only. The longest length of treatment with trastuzumab was over 44 months. And, the median follow-up for overall survival was 13 months (95% confidence interval, 12.7-18.7).

Between 2012 and 2016, five patients died from other causes, including lung cancer, cerebrovascular diseases, aortic aneurysm and dissection, pneumonia and influenza, and heart disease.

“While there are many clinical trials about HER2-positive metastatic breast cancer, these trials were all performed in younger and relatively healthier patients. Few studies included elderly patients 65 years or older,” Ms. Ou said.

According to the American Cancer Society, 31% of all newly diagnosed breast cancer cases are in women who are 70 years old or older, yet 47% of all breast cancer deaths each year are in women in this age group.

Undertreatment and lower treatment intensity have been cited by other studies as possible contributing factors to lower overall survival rates, but breast cancer in elderly women is a complex and understudied subject. Why the mortality rates for elderly women are disproportionately higher than those of younger women is attributable to a number of reasons, write the authors of one of the most recent studies on the subject.

“It is well established that receipt of adjuvant chemotherapy, trastuzumab, and hormonal therapy reduces risk of recurrence and death across all age groups, yet multiple studies document suboptimal systemic treatment and adherence for older patients, including omission of efficacious treatments, receipt of lower intensity and/or nonguideline treatment, or poor adherence to hormonal therapy,” Freedman et al. wrote in the May 15, 2018, issue of the journal Cancer.

While the Ou study sample size was small, the study’s real-world analysis is telling, Ms. Ou said.

“The major limitation of this study is that it has – after applying all the eligibility criteria to the 170,516 breast cancer patients from the SEER-Medicare database between 2012 and 2016 – a study population of just 73 patients. The number is sufficient to do survival analysis,” she said.

A neighborhood analysis of socioeconomic status conducted in the Pittsburgh area found worse metastatic breast cancer survival outcomes among patients of low socioeconomic status. The findings suggest that race is not a relevant factor in outcomes.

“This study demonstrates that metastatic breast cancer patients of low socioeconomic status have worse outcomes than those with higher socioeconomic status at our center. It also underscores the idea that race is not so much a biological construct but more a consequence of socioeconomic issues. The effect of race is likely mediated by lower socioeconomic status,” said Susrutha Puthanmadhom Narayanan, MD, who presented the results of her study earlier this month in Chicago at the annual meeting of the American Society of Clinical Oncology.

“The current study should make clinicians cognizant of the potential for biases in the management of metastatic breast cancer in terms of socioeconomic status and race. One should think of socioeconomic status as a predictor of bad outcomes, almost like a comorbidity, and think of [associations between race and outcomes], as a consequence of socioeconomic inequality,” said Dr. Puthanmadhom Narayanan, who is an internal medicine resident at University of Pittsburgh Medical Center.

She and her colleagues intend to dig deeper into the relationships. “We are interested in looking at utilization of different treatment options for metastatic breast cancer between the socioeconomic status groups. In the preliminary analysis, we saw that ER-positive metastatic breast cancer patients with lower socioeconomic status get treated with tamoxifen more often than aromatase inhibitors and newer agents. And, we have plans to study stress signaling and inflammation as mediators of bad outcomes in the low socioeconomic status population,” Dr. Puthanmadhom Narayanan said.

In fact, that tendency for lower socioeconomic status patients to receive older treatments should be a call to action for physicians. “This study should make clinicians cognizant of the potential for biases in management of metastatic breast cancer in terms of socioeconomic status and race,” she said.

The study is based on an analysis of data from the Neighborhood Atlas in which a Neighborhood Deprivation Index (NDI) score was calculated. An NDI score in the bottom tertile meant that patients were better off than patients with mid to high range NDI scores. In this study, socioeconomic status was described as “low deprivation” or “high depreviation.” Higher deprivation correlated with lower overall survival. And, there were more Black patients in the higher deprivation group (10.5%), compared with the low deprivation group (3.7%). In multivariate Cox proportional hazard model, socioeconomic status, but not race, had a significant effect on overall survival (HR for high deprivation was 1.19 [95% confidence interval; 1.04-1.37], P = 0.01).

It included 1,246 patients who were treated at the University of Pittsburgh Medical Center between 2000 and 2017. Of 1,246 patients, 414 patients considered in the bottom tertile of NDI as having low deprivation, while 832 patients in the middle or top tertiles were classified as having high deprivation.

The two socioeconomic status groups were similar in baseline characteristics, with the exception of race: 10.5% of the high deprivation group were African American, compared with 3.7% of the low deprivation group (P =.000093).

Univariate analyses showed worse survival in both Black women and women in the lower socioeconomic status group, but a multivariate analysis found only socioeconomic status was associated with overall survival (hazard ratio for lower socioeconomic status, 1.19; P = .01).

The study had several strengths, according to Rachel Freedman, MD, MPH, who served as a discussant for the abstract. “It included both de novo and recurrent metastatic breast cancer, unlike previous studies based on the Surveillance, Epidemiology, and End Results (SEER) database that only included de novo cases. It also employed a novel tool to define socioeconomic status in the form of the Neighborhood Atlas. The study “adds more evidence that socioeconomic status likely mediates much of what we see when it comes to racial disparities,” said Dr. Freedman, who is a senior physician at Dana Farber Cancer Institute.

Nevertheless, more work needs to be done. Dr. Freedman pointed out that the current study did not include information on treatment.

The findings underscore the failure to date to address disparities in breast cancer treatment, an effort that is hampered by difficulty in teasing out complex factors that may impact survival. “We need to standardize the way that we collect social determinants of health and act upon findings, and we need to standardize patient navigation, and we need to commit as a community to diverse clinical trial populations,” Dr. Freedman said.

It all began with the question, “Has your butt been getting enough attention?”

Though that may seem unorthodox, it led researchers to discovering a treatment that may help prevent anal cancer in people with HIV/AIDS. It’s still featured on their study’s website, with this further explanation: “You get your viral load checked, your T-cell count checked, but what about your anus? Did you know that half of HIV+ men have cell changes in their anus caused by HPV?”

The Anal Cancer/HSIL Outcomes Research (ANCHOR) study, led by Joel Palefsky, MD, was published  in The New England Journal of Medicine. Dr. Palefsky, an infectious disease expert at the University of California, San Francisco, and his team set out to determine whether a treatment that prevents cervical cancer in people with human papillomavirus (HPV) would benefit people with HIV/AIDS. The new treatment reduced the likelihood of anal cancer by more than 50%.

The team worked over 7 years, during which time they tested 4,459 men, women, transgender, and nonbinary individuals at 25 sites across the United States. The participants were sorted into two groups: Some received treatment for high-grade squamous intraepithelial lesions (HSILs), and some did not but were monitored for signs of disease. These included individuals over 35 who were living with HIV/AIDS and who were found to have patches of abnormal cells in their rectal lining.

HSILs are the cells gynecologists look for in performing a pap smear. They are precancerous cells commonly found in the cervix of persons with HPV. Finding HSILs during a gynecologic examination alerts clinicians to potential problems.

HSILs can also be found in the anal tract of men and women with HIV. Dr. Palefsky therefore hypothesized that, as with HPV and cervical cancer, these anal HSILs may be a precursor of anal cancer.

The scientists decided to treat these cells the same way they would treat them if found in the cervix and to see whether that reduced the risk of cancer. Doctors used lidocaine to numb the area, then removed the HSILs with an electric probe. The team then assessed whether the treatment prevented people from getting cancer.

It turns out that in many cases, it did. The study concluded after 30 of the participants developed anal cancer. Of those, 21 patients had not received HSIL treatment, compared with nine who did receive the treatment. The treatment resulted in a 57% reduction in the rate of anal cancer among patients who received treatment for their HSILs.

These results are encouraging, said Aasma Shaukat, MD, director of outcomes research in the Division of Gastroenterology and Hepatology at NYU Langone Health. Dr. Shaukat was not involved with the study. She believes it’s going to cause ripples across the field.

“The study is likely to change guidelines in favor of active and early treatment for HSIL and away from watchful waiting in individuals living with HIV to reduce the risk of developing anal squamous cell carcinoma, akin to removing polyps during colonoscopy to progression to and incidence of colorectal cancer,” she said in an email interview.

Treatments for this group of patients are more important now than ever. Since the beginning of the AIDS epidemic in the 1980s, the number of people with HIV has increased, Dr. Palefsky detailed in a press conference announcing the ANCHOR results. That’s partially because of new transmissions and partially owing to the fact that new treatments make it possible for people with HIV to live long, healthy lives. So as more people with HIV move into their sunset years, there are more people at risk for developing cancer, which is a disease associated with aging. Anal cancer sits at the intersection of risk for aging people who have HIV.

Any defense we have against the risk of cancer in this growing demographic is a good thing, says Hanna K. Sanoff, MD, a gastrointestinal oncologist at the Lineberger Comprehensive Cancer Center, University of North Carolina at Chapel Hill, who was also not involved in the study. Although it’s not ready to be applied in doctors’ offices now, it could be a tool in the future. “Anything we can do to try and decrease the chance of precancerous lesions progressing to a real invasive cancer is of great importance. This kind of prevention work is critical to helping minimize the burden of cancer on our communities,” Dr. Sanoff said in an interview.

The study was funded by the National Cancer Institute of the National Institutes of Health and was conducted through the NCI-supported AIDS Malignancy Consortium. Dr. Shaukat and Dr. Sanoff report no relevant financial relationships.

It all began with the question, “Has your butt been getting enough attention?”

Though that may seem unorthodox, it led researchers to discovering a treatment that may help prevent anal cancer in people with HIV/AIDS. It’s still featured on their study’s website, with this further explanation: “You get your viral load checked, your T-cell count checked, but what about your anus? Did you know that half of HIV+ men have cell changes in their anus caused by HPV?”

The Anal Cancer/HSIL Outcomes Research (ANCHOR) study, led by Joel Palefsky, MD, was published  in The New England Journal of Medicine. Dr. Palefsky, an infectious disease expert at the University of California, San Francisco, and his team set out to determine whether a treatment that prevents cervical cancer in people with human papillomavirus (HPV) would benefit people with HIV/AIDS. The new treatment reduced the likelihood of anal cancer by more than 50%.

The team worked over 7 years, during which time they tested 4,459 men, women, transgender, and nonbinary individuals at 25 sites across the United States. The participants were sorted into two groups: Some received treatment for high-grade squamous intraepithelial lesions (HSILs), and some did not but were monitored for signs of disease.

Following a diet rich in healthy plant-based products may lower one’s risk of breast cancer, but not if that diet happens to be high in unhealthy foods, researchers have found.

The study of more than 65,000 people showed that plant-based diets that were high in whole grains, fruits, and vegetables appear to be more protective against breast cancer than diets rich in processed plant-based products, such as juice and chips.

“Results suggest that the best plant-based diet for breast cancer prevention could be a healthy plant-based diet comprising fruit, vegetables, whole grains, nuts, and legumes,” said Sanam Shah, MBBS, FCPS, MPH, a doctoral candidate in epidemiology at Paris-Saclay University, who is the lead author of the new study. “In contrast, an unhealthy plant-based diet comprising higher intakes of primarily processed products of plant origin, such as refined grains, fruit juices, sweets, desserts, and potatoes, would be worse for breast cancer prevention.”

Dr. Shah’s group is presenting their research online at the annual meeting of the American Society for Nutrition.

Although the role of plant-based diets in cancer prevention has received extensive attention, Dr. Shah said few studies have assessed the influence of the quality of those diets on the risk of breast cancer.

Dr. Shah and colleagues conducted a prospective cohort study to investigate the link between healthy and unhealthy plant-based diets and breast cancer risk. Unlike other studies, the researchers also evaluated the effect of a gradual decrease in animal products in diets on health.

Dr. Shah’s group followed 65,574 postmenopausal women in France (mean age, 52.8 years) from 1993 to 2014. The researchers used self-reported food questionnaires to classify women into groups on the basis of adherence to a mostly plant or animal diet. Plant-based diets did not exclude meat but had more plant than animal products, Dr. Shah said. The researchers also grouped women on the basis of how healthy the plant-based diets were.

Over the 21-year study period, 3,968 women were diagnosed with breast cancer. Those who adhered to a more healthful plant-based diet had a 14% lower risk than average of developing breast cancer, while those who adhered to a less healthful plant-based diet had a 20% greater risk of developing the disease.

Nutritional quality varies greatly across plant-based foods. Quality plant-based diets should focus on variety to avoid nutritional deficiencies in iron, zinc, calcium, and vitamin B12, Dr. Shah said.

“The study by Shah and coworkers underscores the importance of considering more global aspects of the diet rather than single components when examining relationships between diet and health,” said Megan McCrory, PhD, research associate professor of nutrition at Boston University. “As the study illustrates, plant-based diets as a whole are not always healthy and may also contain less desirable nutrients and foods.”

Abstracts in the conference have been selected by a board of experts for presentation but have not yet been peer reviewed. All findings are to be regarded as preliminary until they are published in peer-reviewed articles. Dr. Shah and Dr. McCrory disclosed no relevant financial relationships.

Sleep time may be a modifiable risk factor for cancer, according to a recent study from Japan.

The findings reveal that sleeping 10-plus hours may increase a woman’s risk of getting cancer and both men and women’s risk of dying from cancer. 

The researchers say their findings may help refine sleep recommendations in Japan, which currently advise working, middle-aged adults to sleep “as long as they can.”

Based on the new findings, a sleep duration of 6-8 hours for men and 6-9 hours for women “may be the safest” regarding cancer incidence and mortality risk among Japanese adults, the authors conclude.

The findings were published online in the International Journal of Cancer. 

The literature on sleep time and cancer risk is mixed. A trio of meta-analyses conducted between 2016 and 2019 found that long sleep duration, but not short, was associated with a slightly elevated risk of all cancer mortality in Asians.

A separate meta-analysis conducted in 2018 found that both short and long sleep durations were not related to cancer incidence. But in the stratified analysis, shorter sleep time was associated with 36% increased cancer risk among Asians.

To investigate further, the researchers pooled data from six population-based cohorts that included 271,694 adults – 126,930 men and 144,764 women – with 40,751 total incident cancer cases and 18,323 total cancer deaths during a follow-up lasting about 5.9 million person-years.

In the multivariable analysis, longer sleep duration was not associated with total cancer incidence in men. In women, however, sleeping 10 or more hours vs. 7 was associated with a 19% increased risk of cancer.

In addition, sleeping 10 or more hours was associated with an increased risk of dying from cancer in women (hazard ratio, 1.44) and men (HR, 1.18).

Sleeping for 5 hours or fewer, compared with 7, was not associated with cancer incidence and mortality. However, among postmenopausal women, shorter sleep durations did increase the risk of dying from cancer (HR, 1.15).

The authors highlight several strengths of the analysis, including a large sample size as well as stratification of the results by body mass index and menopause status, which has rarely been done in previous studies.

Limitations include self-reported sleep durations and lack of data on sleep quality. The researchers note that the mechanism by which sleep time may influence cancer incidence and mortality is unclear but likely to be complex and cancer site specific.

It’s also possible that reverse causation could explain associations between sleep duration and cancer occurrence and mortality – with pain from cancer, for instance, impairing sleep duration and quality. However, the sensitivity analysis found no evidence of reverse causality or other confounding factors.

Based on these findings, the researchers say sleep duration “may be an important variable to include in cancer incidence and mortality risk prediction models.”

The study had no specific funding. The authors declared no relevant conflicts of interest.

CHICAGO – Progress in breast cancer treatment over the past 2 decades has reduced expected mortality from both early-stage and metastatic disease, according to a new model that looked at 10-year distant recurrence-free survival and survival time after metastatic diagnosis, among other factors.

“There has been an accelerating influx of new treatments for breast cancer starting around 1990. We wished to ask whether and to what extent decades of metastatic treatment advances may have affected population level breast cancer mortality,” said Jennifer Lee Caswell-Jin, MD, during a presentation of the study at the annual meeting of the American Society of Clinical Oncology.

“Our models find that metastatic treatments improved population-level survival in all breast cancer subtypes since 2000 with substantial variability by subtype," said Dr. Caswell-Jin, who is a medical oncologist with Stanford (Calif.) Medicine specializing in breast cancer.

The study is based on an analysis of four models from the Cancer Intervention and Surveillance Modeling Network (CISNET). The models simulated breast cancer mortality between 2000 and 2019 factoring in the use of mammography, efficacy and dissemination of estrogen receptor (ER) and HER2-specific treatments of early-stage (stages I-III) and metastatic (stage IV or distant recurrence) disease, but also non–cancer-related mortality. The models compared overall and ER/HER2-specific breast cancer mortality rates during this period with estimated rates with no screening or treatment, and then attributed mortality reductions to screening, early-stage, or metastatic treatment.

The results were compared with three clinical trials that tested therapies in different subtypes of metastatic disease. Dr. Caswell-Jin and colleagues adjusted the analysis to reflect expected differences between clinical trial populations and the broader population by sampling simulated patients who resembled the trial population.

The investigators found that, at 71%, the biggest drop in mortality rates were for women with ER+/HER2+ breast cancer, followed by 61% for women with ER-/HER2+ breast cancer and 59% for women with ER+/HER2– breast cancer. Triple-negative breast cancer – one of the most challenging breast cancers to treat – only saw a drop of 40% during this period. About 19% of the overall reduction in breast cancer mortality were caused by treatments after metastasis.

The median survival after a diagnosis of ER+/HER2– metastatic recurrence increased from 2 years in 2000 to 3.5 years in 2019. In triple-negative breast cancer, the increase was more modest, from 1.2 years in 2000 to 1.8 years in 2019. After a diagnosis of metastatic recurrence of ER+/HER2+ breast cancer, median survival increased from 2.3 years in 2000 to 4.8 years in 2019, and for ER–/HER2+ breast cancer, from 2.2 years in 2000 to 3.9 years in 2019.

“How much metastatic treatments contributed to the overall mortality reduction varied over time depending on what therapies were entering the metastatic setting at that time and what therapies were transitioning from the metastatic to early-stage setting,” Dr. Caswell-Jin said.

The study did not include sacituzumab govitecan for metastatic triple-negative breast cancer, or trastuzumab deruxtecan and tucatinib for HER2-positive disease, which were approved after 2020. “The numbers that we cite will be better today for triple-negative breast cancer because of those two drugs. And will be even better for HER2-positive breast cancer because of those two drugs,” she said.

During the Q&A portion of the presentation, Daniel Hayes, MD, the Stuart B. Padnos Professor of Breast Cancer Research at the University of Michigan Rogel Cancer Center, Ann Arbor, asked about the potential of CISNET as an in-practice diagnostic tool.

“We’ve traditionally told patients who have metastatic disease that they will not be cured. I told two patients that on Tuesday.

CHICAGO – Progress in breast cancer treatment over the past 2 decades has reduced expected mortality from both early-stage and metastatic disease, according to a new model that looked at 10-year distant recurrence-free survival and survival time after metastatic diagnosis, among other factors.

“There has been an accelerating influx of new treatments for breast cancer starting around 1990. We wished to ask whether and to what extent decades of metastatic treatment advances may have affected population level breast cancer mortality,” said Jennifer Lee Caswell-Jin, MD, during a presentation of the study at the annual meeting of the American Society of Clinical Oncology.

“Our models find that metastatic treatments improved population-level survival in all breast cancer subtypes since 2000 with substantial variability by subtype," said Dr. Caswell-Jin, who is a medical oncologist with Stanford (Calif.) Medicine specializing in breast cancer.

The study is based on an analysis of four models from the Cancer Intervention and Surveillance Modeling Network (CISNET). The models simulated breast cancer mortality between 2000 and 2019 factoring in the use of mammography, efficacy and dissemination of estrogen receptor (ER) and HER2-specific treatments of early-stage (stages I-III) and metastatic (stage IV or distant recurrence) disease, but also non–cancer-related mortality. The models compared overall and ER/HER2-specific breast cancer mortality rates during this period with estimated rates with no screening or treatment, and then attributed mortality reductions to screening, early-stage, or metastatic treatment.

The results were compared with three clinical trials that tested therapies in different subtypes of metastatic disease. Dr. Caswell-Jin and colleagues adjusted the analysis to reflect expected differences between clinical trial populations and the broader population by sampling simulated patients who resembled the trial population.

The investigators found that, at 71%, the biggest drop in mortality rates were for women with ER+/HER2+ breast cancer, followed by 61% for women with ER-/HER2+ breast cancer and 59% for women with ER+/HER2– breast cancer. Triple-negative breast cancer – one of the most challenging breast cancers to treat – only saw a drop of 40% during this period. About 19% of the overall reduction in breast cancer mortality were caused by treatments after metastasis.

The median survival after a diagnosis of ER+/HER2– metastatic recurrence increased from 2 years in 2000 to 3.5 years in 2019. In triple-negative breast cancer, the increase was more modest, from 1.2 years in 2000 to 1.8 years in 2019. After a diagnosis of metastatic recurrence of ER+/HER2+ breast cancer, median survival increased from 2.3 years in 2000 to 4.8 years in 2019, and for ER–/HER2+ breast cancer, from 2.2 years in 2000 to 3.9 years in 2019.

“How much metastatic treatments contributed to the overall mortality reduction varied over time depending on what therapies were entering the metastatic setting at that time and what therapies were transitioning from the metastatic to early-stage setting,” Dr. Caswell-Jin said.

The study did not include sacituzumab govitecan for metastatic triple-negative breast cancer, or trastuzumab deruxtecan and tucatinib for HER2-positive disease, which were approved after 2020. “The numbers that we cite will be better today for triple-negative breast cancer because of those two drugs. And will be even better for HER2-positive breast cancer because of those two drugs,” she said.

During the Q&A portion of the presentation, Daniel Hayes, MD, the Stuart B. Padnos Professor of Breast Cancer Research at the University of Michigan Rogel Cancer Center, Ann Arbor, asked about the potential of CISNET as an in-practice diagnostic tool.

“We’ve traditionally told patients who have metastatic disease that they will not be cured. I told two patients that on Tuesday. Can CISNET modeling let us begin to see if there is indeed now, with the improved therapies we have, a group of patients who do appear to be cured, or is that not possible?” he asked.
