Are Food Emulsifiers Associated With Increased Cancer Risk?
Food emulsifiers are among the most widespread food additives.
Ultraprocessed foods constitute a significant part of our diet, representing approximately 30% of energy intake in France.
Large epidemiologic studies have already linked diets rich in ultraprocessed products to an increased risk for cardiovascular diseases, diabetes, obesity, and mortality. Possible explanations for this association include the presence of additives, particularly emulsifiers. These additives are intended to improve the texture and shelf life of foods.
Recent experimental studies have shown that emulsifiers alter the gut microbiota and may lead to low-grade inflammation. Dysbiosis and chronic inflammation not only increase the risk for inflammatory bowel diseases but are also implicated in the etiology of several other chronic pathologies and certain extraintestinal cancers.
The NutriNet-Santé study provided extensive information on the dietary habits of > 100,000 French participants. A new analysis was conducted, examining the possible link between the presence of emulsifiers in the diet and cancer occurrence. Data from 92,000 participants (78.8% women) were utilized. They covered an average follow-up of 6.7 years, during which 2604 cancer cases were diagnosed, including 750 breast cancers, 322 prostate cancers, and 207 colorectal cancers.
In this cohort, the risk for cancer increased with a higher presence in the diet of products containing certain emulsifiers widely used in industrial food in Europe: Carrageenans (E407), mono- and diglycerides of fatty acids (E471), pectins (E440), and sodium carbonate (E500).
Notably, the highest consumption of mono- and diglycerides of fatty acids (E471) was associated with a 15% increase in the risk for all types of cancer, a 24% increase in breast cancer risk, and a 46% increase in prostate cancer risk. The highest consumption of carrageenans (E407) was associated with a 28% increase in breast cancer risk.
In an analysis by menopausal status, the risk for breast cancer before menopause was associated with high consumption of diphosphates (E450; 45% increase), pectins (E440; 55% increase), and sodium bicarbonate (E500; 48% increase). No link was found between emulsifier consumption and colorectal cancer risk. While some associations were observed for other emulsifiers, they did not persist in sensitivity analyses.
The European Food Safety Agency recently evaluated the risks of emulsifiers, however, and found no safety issues or need to limit daily consumption of several of them, notably E471.
It is certain that cancer is multifactorial, and a single factor (here, exposure to emulsifiers) will not significantly increase the risk. However, while not essential to human health, emulsifiers are widely prevalent in the global market. Therefore, if causality is established, the increased risk could translate into a significant number of preventable cancers at the population level. Confirmation of this causal link will need to be obtained through experimental and epidemiological studies.

Democratic Lawmakers Press Pfizer on Chemotherapy Drug Shortages
In a statement about their February 21 action, the legislators, led by Rep. Jamie Raskin (D-Md.), the committee’s ranking minority member, described their work as a follow up to an earlier investigation into price hikes of generic drugs. While the committee members queried Pfizer over the three oncology medications only, they also sent letters to drugmakers Teva and Sandoz with respect to shortages in other drug classes.
A representative for Pfizer confirmed to MDedge Oncology that the company had received the representatives’ letter but said “we have no further details to provide at this time.”
What is the basis for concern?
All three generic chemotherapy drugs are mainstay treatments used across a broad array of cancers. Though shortages have been reported for several years, they became especially acute after December 2022, when an inspection by the US Food and Drug Administration (FDA) led to regulatory action against an Indian manufacturer, Intas, that produced up to half of the platinum-based therapies supplied globally. The National Comprehensive Cancer Care Network reported in October 2023 that more than 90% of its member centers were struggling to maintain adequate supplies of carboplatin, and 70% had trouble obtaining cisplatin, while the American Society of Clinical Oncology published clinical guidance on alternative treatment strategies.
What has the government done in response to the recent shortages?
The White House and the FDA announced in September that they were working with several manufacturers to help increase supplies of the platinum-based chemotherapies and of methotrexate, and taking measures that included relaxing rules on imports. Recent guidance under a pandemic-era federal law, the 2020 CARES Act, strengthened manufacturer reporting requirements related to drug shortages, and other measures have been proposed. While federal regulators have many tools with which to address drug shortages, they cannot legally oblige a manufacturer to increase production of a drug.
What can the lawmakers expect to achieve with their letter?
By pressuring Pfizer publicly, the lawmakers may be able to nudge the company to take measures to assure more consistent supplies of the three drugs. The lawmakers also said they hoped to glean from Pfizer more insight into the root causes of the shortages and potential remedies. They noted that, in a May 2023 letter by Pfizer to customers, the company had warned of depleted and limited supplies of the three drugs and said it was “working diligently” to increase output. However, the lawmakers wrote, “the root cause is not yet resolved and carboplatin, cisplatin, and methotrexate continue to experience residual delays.”
Why did the committee target Pfizer specifically?
Pfizer and its subsidiaries are among the major manufacturers of the three generic chemotherapy agents mentioned in the letter. The legislators noted that “pharmaceutical companies may not be motivated to produce generic drugs like carboplatin, cisplatin, and methotrexate, because they are not as lucrative as producing patented brand name drugs,” and that “as a principal supplier of carboplatin, cisplatin, and methotrexate, it is critical that Pfizer continues to increase production of these life-sustaining cancer medications, even amidst potential lower profitability.”
The committee members also made reference to news reports of price-gouging with these medications, as smaller hospitals or oncology centers are forced to turn to unscrupulous third-party suppliers.
What is being demanded of Pfizer?
Pfizer was given until March 6 to respond, in writing and in a briefing with committee staff, to a six questions. These queries concern what specific steps the company has taken to increase supplies of the three generic oncology drugs, what Pfizer is doing to help avert price-gouging, whether further oncology drug shortages are anticipated, and how the company is working with the FDA on the matter.

Unleashing Our Immune Response to Quash Cancer
This article was originally published on February 10 in Eric Topol’s substack “Ground Truths.”
It’s astounding how devious cancer cells and tumor tissue can be. This week in Science we learned how certain lung cancer cells can function like “Catch Me If You Can” — changing their driver mutation and cell identity to escape targeted therapy. This histologic transformation, as seen in an experimental model, is just one of so many cancer tricks that we are learning about.
Recently, as shown by single-cell sequencing, cancer cells can steal the mitochondria from T cells, a double whammy that turbocharges cancer cells with the hijacked fuel supply and, at the same time, dismantles the immune response.
Last week, we saw how tumor cells can release a virus-like protein that unleashes a vicious autoimmune response.
And then there’s the finding that cancer cell spread predominantly is occurring while we sleep.
As I previously reviewed, the ability for cancer cells to hijack neurons and neural circuits is now well established, no less their ability to reprogram neurons to become adrenergic and stimulate tumor progression, and interfere with the immune response. Stay tuned on that for a new Ground Truths podcast with Prof Michelle Monje, a leader in cancer neuroscience, which will post soon.
Add advancing age’s immunosenescence as yet another challenge to the long and growing list of formidable ways that cancer cells, and the tumor microenvironment, evade our immune response.
An Ever-Expanding Armamentarium
Immune Checkpoint Inhibitors
The field of immunotherapies took off with the immune checkpoint inhibitors, first approved by the FDA in 2011, that take the brakes off of T cells, with the programmed death-1 (PD-1), PD-ligand1, and anti-CTLA-4 monoclonal antibodies.
But we’re clearly learning they are not enough to prevail over cancer with common recurrences, only short term success in most patients, with some notable exceptions. Adding other immune response strategies, such as a vaccine, or antibody-drug conjugates, or engineered T cells, are showing improved chances for success.
Therapeutic Cancer Vaccines
There are many therapeutic cancer vaccines in the works, as reviewed in depth here.
Here’s a list of ongoing clinical trials of cancer vaccines. You’ll note most of these are on top of a checkpoint inhibitor and use personalized neoantigens (cancer cell surface proteins) derived from sequencing (whole-exome or whole genome, RNA-sequencing and HLA-profiling) the patient’s tumor.
An example of positive findings is with the combination of an mRNA-nanoparticle vaccine with up to 34 personalized neoantigens and pembrolizumab (Keytruda) vs pembrolizumab alone in advanced melanoma after resection, with improved outcomes at 3-year follow-up, cutting death or relapse rate in half.
Antibody-Drug Conjugates (ADC)
There is considerable excitement about antibody-drug conjugates (ADC) whereby a linker is used to attach a chemotherapy agent to the checkpoint inhibitor antibody, specifically targeting the cancer cell and facilitating entry of the chemotherapy into the cell. Akin to these are bispecific antibodies (BiTEs, binding to a tumor antigen and T cell receptor simultaneously), both of these conjugates acting as “biologic” or “guided” missiles.
A very good example of the potency of an ADC was seen in a “HER2-low” breast cancer randomized trial. The absence or very low expression or amplification of the HER2 receptor is common in breast cancer and successful treatment has been elusive. A randomized trial of an ADC (trastuzumab deruxtecan) compared to physician’s choice therapy demonstrated a marked success for progression-free survival in HER2-low patients, which was characterized as “unheard-of success” by media coverage.
This strategy is being used to target some of the most difficult cancer driver mutations such as TP53 and KRAS.
Oncolytic Viruses
Modifying viruses to infect the tumor and make it more visible to the immune system, potentiating anti-tumor responses, known as oncolytic viruses, have been proposed as a way to rev up the immune response for a long time but without positive Phase 3 clinical trials.
After decades of failure, a recent trial in refractory bladder cancer showed marked success, along with others, summarized here, now providing very encouraging results. It looks like oncolytic viruses are on a comeback path.
Engineering T Cells (Chimeric Antigen Receptor [CAR-T])
As I recently reviewed, there are over 500 ongoing clinical trials to build on the success of the first CAR-T approval for leukemia 7 years ago. I won’t go through that all again here, but to reiterate most of the success to date has been in “liquid” blood (leukemia and lymphoma) cancer tumors. This week in Nature is the discovery of a T cell cancer mutation, a gene fusion CARD11-PIK3R3, from a T cell lymphoma that can potentially be used to augment CAR-T efficacy. It has pronounced and prolonged effects in the experimental model. Instead of 1 million cells needed for treatment, even 20,000 were enough to melt the tumor. This is a noteworthy discovery since CAR-T work to date has largely not exploited such naturally occurring mutations, while instead concentrating on those seen in the patient’s set of key tumor mutations.
As currently conceived, CAR-T, and what is being referred to more broadly as adoptive cell therapies, involves removing T cells from the patient’s body and engineering their activation, then reintroducing them back to the patient. This is laborious, technically difficult, and very expensive. Recently, the idea of achieving all of this via an injection of virus that specifically infects T cells and inserts the genes needed, was advanced by two biotech companies with preclinical results, one in non-human primates.
Gearing up to meet the challenge of solid tumor CAR-T intervention, there’s more work using CRISPR genome editing of T cell receptors. A.I. is increasingly being exploited to process the data from sequencing and identify optimal neoantigens.
Instead of just CAR-T, we’re seeing the emergence of CAR-macrophage and CAR-natural killer (NK) cells strategies, and rapidly expanding potential combinations of all the strategies I’ve mentioned. No less, there’s been maturation of on-off suicide switches programmed in, to limit cytokine release and promote safety of these interventions. Overall, major side effects of immunotherapies are not only cytokine release syndromes, but also include interstitial pneumonitis and neurotoxicity.
Summary
Given the multitude of ways cancer cells and tumor tissue can evade our immune response, durably successful treatment remains a daunting challenge. But the ingenuity of so many different approaches to unleash our immune response, and their combinations, provides considerable hope that we’ll increasingly meet the challenge in the years ahead. We have clearly learned that combining different immunotherapy strategies will be essential for many patients with the most resilient solid tumors.
Of concern, as noted by a recent editorial in The Lancet, entitled “Cancer Research Equity: Innovations For The Many, Not The Few,” is that these individualized, sophisticated strategies are not scalable; they will have limited reach and benefit. The movement towards “off the shelf” CAR-T and inexpensive, orally active checkpoint inhibitors may help mitigate this issue.
Notwithstanding this important concern, we’re seeing an array of diverse and potent immunotherapy strategies that are providing highly encouraging results, engendering more excitement than we’ve seen in this space for some time. These should propel substantial improvements in outcomes for patients in the years ahead. It can’t happen soon enough.

It’s astounding how devious cancer cells and tumor tissue can be. This week in Science we learned how certain lung cancer cells can function like “Catch Me If You Can” — changing their driver mutation and cell identity to escape targeted therapy. This histologic transformation, as seen in an experimental model, is just one of so many cancer tricks that we are learning about.
Recently, as shown by single-cell sequencing, cancer cells can steal the mitochondria from T cells, a double whammy that turbocharges cancer cells with the hijacked fuel supply and, at the same time, dismantles the immune response.
Last week, we saw how tumor cells can release a virus-like protein that unleashes a vicious autoimmune response.
And then there’s the finding that cancer cell spread predominantly is occurring while we sleep.
As I previously reviewed, the ability for cancer cells to hijack neurons and neural circuits is now well established, no less their ability to reprogram neurons to become adrenergic and stimulate tumor progression, and interfere with the immune response. Stay tuned on that for a new Ground Truths podcast with Prof Michelle Monje, a leader in cancer neuroscience, which will post soon.
Add advancing age’s immunosenescence as yet another challenge to the long and growing list of formidable ways that cancer cells, and the tumor microenvironment, evade our immune response.
An Ever-Expanding Armamentarium
Immune Checkpoint Inhibitors
The field of immunotherapies took off with the immune checkpoint inhibitors, first approved by the FDA in 2011, that take the brakes off of T cells, with the programmed death-1 (PD-1), PD-ligand1, and anti-CTLA-4 monoclonal antibodies.
But we’re clearly learning they are not enough to prevail over cancer with common recurrences, only short term success in most patients, with some notable exceptions. Adding other immune response strategies, such as a vaccine, or antibody-drug conjugates, or engineered T cells, are showing improved chances for success.
Therapeutic Cancer Vaccines
There are many therapeutic cancer vaccines in the works, as reviewed in depth here.
Here’s a list of ongoing clinical trials of cancer vaccines. You’ll note most of these are on top of a checkpoint inhibitor and use personalized neoantigens (cancer cell surface proteins) derived from sequencing (whole-exome or whole genome, RNA-sequencing and HLA-profiling) the patient’s tumor.
An example of positive findings is with the combination of an mRNA-nanoparticle vaccine with up to 34 personalized neoantigens and pembrolizumab (Keytruda) vs pembrolizumab alone in advanced melanoma after resection, with improved outcomes at 3-year follow-up, cutting death or relapse rate in half.
Antibody-Drug Conjugates (ADC)
There is considerable excitement about antibody-drug conjugates (ADC) whereby a linker is used to attach a chemotherapy agent to the checkpoint inhibitor antibody, specifically targeting the cancer cell and facilitating entry of the chemotherapy into the cell. Akin to these are bispecific antibodies (BiTEs, binding to a tumor antigen and T cell receptor simultaneously), both of these conjugates acting as “biologic” or “guided” missiles.
A very good example of the potency of an ADC was seen in a “HER2-low” breast cancer randomized trial. The absence or very low expression or amplification of the HER2 receptor is common in breast cancer and successful treatment has been elusive. A randomized trial of an ADC (trastuzumab deruxtecan) compared to physician’s choice therapy demonstrated a marked success for progression-free survival in HER2-low patients, which was characterized as “unheard-of success” by media coverage.
This strategy is being used to target some of the most difficult cancer driver mutations such as TP53 and KRAS.
Oncolytic Viruses
Modifying viruses to infect the tumor and make it more visible to the immune system, potentiating anti-tumor responses, known as oncolytic viruses, have been proposed as a way to rev up the immune response for a long time but without positive Phase 3 clinical trials.
After decades of failure, a recent trial in refractory bladder cancer showed marked success, along with others, summarized here, now providing very encouraging results. It looks like oncolytic viruses are on a comeback path.
Engineering T Cells (Chimeric Antigen Receptor [CAR-T])
As I recently reviewed, there are over 500 ongoing clinical trials to build on the success of the first CAR-T approval for leukemia 7 years ago. I won’t go through that all again here, but to reiterate most of the success to date has been in “liquid” blood (leukemia and lymphoma) cancer tumors. This week in Nature is the discovery of a T cell cancer mutation, a gene fusion CARD11-PIK3R3, from a T cell lymphoma that can potentially be used to augment CAR-T efficacy. It has pronounced and prolonged effects in the experimental model. Instead of 1 million cells needed for treatment, even 20,000 were enough to melt the tumor. This is a noteworthy discovery since CAR-T work to date has largely not exploited such naturally occurring mutations, while instead concentrating on those seen in the patient’s set of key tumor mutations.
As currently conceived, CAR-T, and what is being referred to more broadly as adoptive cell therapies, involves removing T cells from the patient’s body and engineering their activation, then reintroducing them back to the patient. This is laborious, technically difficult, and very expensive. Recently, the idea of achieving all of this via an injection of virus that specifically infects T cells and inserts the genes needed, was advanced by two biotech companies with preclinical results, one in non-human primates.
Gearing up to meet the challenge of solid tumor CAR-T intervention, there’s more work using CRISPR genome editing of T cell receptors. A.I. is increasingly being exploited to process the data from sequencing and identify optimal neoantigens.
Instead of just CAR-T, we’re seeing the emergence of CAR-macrophage and CAR-natural killer (NK) cells strategies, and rapidly expanding potential combinations of all the strategies I’ve mentioned. No less, there’s been maturation of on-off suicide switches programmed in, to limit cytokine release and promote safety of these interventions. Overall, major side effects of immunotherapies are not only cytokine release syndromes, but also include interstitial pneumonitis and neurotoxicity.
Summary
Given the multitude of ways cancer cells and tumor tissue can evade our immune response, durably successful treatment remains a daunting challenge. But the ingenuity of so many different approaches to unleash our immune response, and their combinations, provides considerable hope that we’ll increasingly meet the challenge in the years ahead. We have clearly learned that combining different immunotherapy strategies will be essential for many patients with the most resilient solid tumors.
Of concern, as noted by a recent editorial in The Lancet, entitled “Cancer Research Equity: Innovations For The Many, Not The Few,” is that these individualized, sophisticated strategies are not scalable; they will have limited reach and benefit. The movement towards “off the shelf” CAR-T and inexpensive, orally active checkpoint inhibitors may help mitigate this issue.
Notwithstanding this important concern, we’re seeing an array of diverse and potent immunotherapy strategies that are providing highly encouraging results, engendering more excitement than we’ve seen in this space for some time. These should propel substantial improvements in outcomes for patients in the years ahead. It can’t happen soon enough.

Radiation Oncologists Fight for Payment Reform Amid Cuts
The American Society for Radiation Oncology (ASTRO) recently announced its partnership with three other groups — the American College of Radiation Oncology, the American College of Radiology, and the American Society of Clinical Oncology — to change how the specialty is paid for services.
Over the past decade, radiation oncologists have seen a 23% drop in Medicare reimbursement for radiation therapy services, with more cuts to come, according to a press release from ASTRO.
Traditionally, Medicare has reimbursed on the basis of the fraction of radiation delivered. But with moves toward hypofractionated regimens, deescalated therapy, and other changes in the field, reimbursement has continued to dwindle.
The cuts have led to practice consolidation and closures that threaten patient access especially in rural and underserved areas, a spokesperson for the group told this news organization.
To reverse this trend, ASTRO recently proposed the Radiation Oncology Case Rate program, a legislative initiative to base reimbursements on patient volumes instead of fractions delivered.
ASTRO is currently drafting a congressional bill to change the current payment structure, which “has become untenable,” the spokesperson said.

ADC with radiotherapy for brain mets ups risk of necrosis
TOPLINE:
, a new retrospective study suggests.
METHODOLOGY:
- Stereotactic radiotherapy is a key treatment for patients with brain metastases, but some develop radiation necrosis. Because ADCs can help shrink brain metastases as well, the researchers wanted to see whether adding an ADC to stereotactic radiotherapy increased patients’ risk of symptomatic radiation necrosis.
- The study included 98 patients (84% women; median age, 55 years) with brain metastases who received at least one course of stereotactic radiotherapy for intact brain metastases and at least one dose of trastuzumab emtansine, trastuzumab deruxtecan, or sacituzumab govitecan.
- Stereotactic radiotherapy was considered concurrent with ADC therapy if delivered within 7 days before the ADC or within 21 days after the ADC. The control cohort included patients with brain metastases treated sequentially with stereotactic radiotherapy and an ADC.
- Symptomatic radiation necrosis was the primary outcome, and the researchers used competing risks regression models to analyze the impact of concurrent therapy.
TAKEAWAY:
- For the entire cohort, the 24-month cumulative incidence of symptomatic radiation necrosis was 8.5%. ADC therapy given concurrently with stereotactic radiotherapy was associated with higher risk for symptomatic radiation necrosis in univariable analysis (subdistribution hazard ratio, 4.01) and multivariable analysis (SHR, 4.31) that controlled for prior radiotherapy and volume of brain metastases.
- The risk of symptomatic radiation necrosis with concurrent ADC was modest for patients with small brain metastases who received a first course of stereotactic radiotherapy but was substantial for those with larger and reirradiated lesions treated with concurrent ADC.
- For previously radiated lesions, the 24-month risk of necrosis was 42% with concurrent ADC versus 9.4% without concurrent ADC.
- Grade 4-5 symptomatic radiation necrosis following stereotactic radiotherapy was observed in 7.1% of brain metastases treated with concurrent ADC versus 0.7% treated without concurrent ADC. There was no difference in risk between different ADC agents.
IN PRACTICE:
On the basis of current findings, the researchers concluded that “clinicians should be cognizant of the [symptomatic radiation necrosis] risk and monitor patients closely when treating concurrently with ADCs.”
SOURCE:
The study, with first author Emily S. Lebow, MD, of Memorial Sloan Kettering Cancer Center in New York, was published online in JAMA Oncology.
LIMITATIONS:
Limitations include the retrospective study design as well as uncertainty in discriminating between radiation necrosis and local treatment failure.
DISCLOSURES:
The study had no specific funding. Four of the six authors reported various relationships with industry.

Multiprong strategy makes clinical trials less White
CHICAGO – Clinical trials are so White. Only a small percentage of eligible patients participate in clinical trials in the first place, and very few come from racial and ethnic minority groups.
For example, according to the Food and Drug Administration, in trials that resulted in drug approvals from 2017 to 2020, only 2%-5% of participants were Black patients.
When clinical trials lack diverse patient populations, those who are left out have fewer opportunities to get new therapies. Moreover, the scope of the research is limited by smaller phenotypic and genotypic samples, and the trial results are applicable only to more homogeneous patient groups.
There has been a push to include more underrepresented patients in clinical trials. One group reported its success in doing so here at the annual meeting of the American Society of Clinical Oncology.
a period that included a pandemic-induced hiatus in clinical trials in general.
Alliance member Electra D. Paskett, PhD, from the College of Public Health at the Ohio State University in Columbus, presented accrual data from 117 trials led by the Alliance from 2014 to 2022.
During this period, accrual of racial and ethnic minority patients increased from 13.6% to 25.3% for cancer treatment trials and from 13% to 21.5% for cancer control trials.
Overall, the recruitment program resulted in an absolute increase from 13.5 % to 23.6% of underrepresented populations, which translated into a relative 74.8% improvement.
“We’re focusing now on monitoring accrual of women, rural populations, younger AYAs [adolescents and young adults] and older patients, and we’ll see what strategies we need to implement,” Dr. Packett told this news organization.
The Alliance has implemented a real-time accrual dashboard on its website that allows individual sites to review accrual by trial and overall for all of the identified underrepresented populations, she noted.
Program to increase underrepresented patient accrual
The impetus for the program to increase enrollment of underrepresented patients came from the goal set by Monica M. Bertagnolli, MD, group chair of the Alliance from 2011 to 2022 and currently the director of the U.S. National Cancer Institute.
“Our leader, Dr. Bertagnolli, set out a group-wide goal for accrual of underrepresented minorities to our trials of 20%, and that gave us permission to implement a whole host of new strategies,” Dr. Paskett said in an interview.
“These strategies follow the Accrual of Clinical Trials framework, which essentially says that the interaction between the patient and the provider for going on a clinical trial is not just an interaction between the patient and provider but recognizes, for example, that the provider has coworkers and they have norms and beliefs and attitudes, and the patient comes from a family with their own values. And then there are system-level barriers, and there are community barriers that all relate to this interaction about going on a trial,” Dr. Packett said.
What works?
The study was presented as a poster at the meeting. During the poster discussion session, comoderator Victoria S. Blinder, MD, from Memorial Sloan Kettering Cancer Center in New York, asked Dr. Paskett, “If you had a certain amount of money and you really wanted to use that resource to focus on one area, where would you put that resource?”
“I’m going to violate the rules of your question,” Dr. Paskett replied.
“You cannot change this problem by focusing on one thing, and that’s what we showed in our Alliance poster, and what I’ve said is based on over 30 years of work in this area,” she said.
She cited what she considered as the two most important components for improving accrual of underrepresented populations: a commitment by leadership to a recruitment goal, and the development of protocols with specific accrual goals for minority populations.
Still, those are only two components of a comprehensive program that includes the aforementioned accrual goal set by Dr. Bertagnolli, as well as the following:
- Funding of minority junior investigators and research that focuses on issues of concern to underrepresented populations.
- Establishment of work groups that focus on specific populations with the Alliance health disparities committee.
- Translation of informational materials for patients.
- Opening studies at National Cancer Institute Community. Oncology Research Program–designated minority underserved sites.
- Real-time monitoring of accrual demographics by the Alliance and at the trial site.
- Closing protocol enrollment to majority populations.
- Increasing the study sample sizes to enroll additional minority participants and to allow for subgroup analyses.
The study was funded by the National Institutes of Health. Dr. Packett and Dr. Blinder reported no relevant financial relationships.

AT ASCO 2023
CBSM phone app eases anxiety, depression in cancer patients
CHICAGO – One-third of patients with cancer also experience anxiety or depression, and an estimated 70% of the 18 million patients with cancer and cancer survivors in the US experience emotional symptoms, including fear of recurrence.
Despite many having these symptoms, few patients with cancer have access to psycho-oncologic support.
A digital cognitive-behavioral stress management (CBSM) application may help to ease some of the burden, reported Allison Ramiller, MPH, of Blue Note Therapeutics in San Francisco, which developed the app version of the program.
In addition, patients assigned to the CBSM app were twice as likely as control persons to report that their symptoms were “much” or “very much” improved after using the app for 12 weeks, Ms. Ramiller reported at an oral abstract session at the annual meeting of the American Society of Clinical Oncology (ASCO).
However, the investigators did not report baseline characteristics of patients in each of the study arms, which might have helped to clarify the depth of the effects they saw.
The CBSM program was developed by Michael H. Antoni, PhD, and colleagues in the University of Miami Health System. It is based on cognitive-behavioral therapy but also includes stress management and relaxation techniques to help patients cope with cancer-specific stress.
“”It has been clinically validated and shown to benefit patients with cancer,” Ms. Ramiller said. “However, access is a problem,” she said.
“There aren’t enough qualified, trained providers for the need, and patients with cancer encounter barriers to in-person participation, including things like transportation or financial barriers. So to overcome this, we developed a digitized version of CBSM,” she explained.
Impressive and elegant
“Everything about [the study] I thought was very impressive, very elegant, very nicely done,” said invited discussant Raymond U. Osarogiagbon, MBBS, FACP, chief scientist at Baptist Memorial Health Care Corp in Memphis, Tenn.
“They showed efficacy, they showed safety – very nice – user friendliness – very good. Certainly they look like they’re trying to address a highly important, unmet need in a very elegant way. Certainly, they pointed out it needs longer follow-up to see sustainability. We need to see will this work in other settings. Will this be cost-effective? You’ve gotta believe it probably will be,” he said.
CBSM has previously been shown to help patients with cancer reduce stress, improve general and cancer-specific quality of life at various stages of treatment, reduce symptom burden, and improve coping skills, Ms. Ramiller said.
To see whether these benefits could be conveyed digitally rather than in face-to-face encounters, Ms. Ramiller and colleagues worked with Dr. Antoni to develop the CBSM app.
Patients using the app received therapeutic content over 10 sessions with audio, video, and interactive tools that mimicked the sessions they would have received during in-person interventions.
They then compared the app against the control educational app in the randomized, decentralized RESTORE study.
High-quality control
Ms. Ramiller said that the control app set “a high bar.”
“The control also offered 10 interactive self-guided sessions. Both treatment apps were professionally designed and visually similar in styling, and they were presented as digital therapeutic-specific for cancer patients. And they were also in a match condition, meaning they received the same attention from study staff and cadence of reminders, but importantly, only the intervention app was based on CBSM,” she explained.
A total of 449 patients with cancers of stage I–III who were undergoing active systemic treatment or were planning to undergo such treatment within 6 months were randomly assigned to the CBSM app or the control app.
The CBSM app was superior to the control app for the primary outcome of anxiety reduction over baseline, as measured at 4, 8 and 12 weeks by the Patient-Reported Outcomes Measurement Information System Anxiety Scale (PROMIS-A) (beta = -.03; P = .019).
CBSM was also significantly better than the control app for the secondary endpoints of reducing symptoms of depression, as measured by the PROMIS-D scale (beta = -.02, P = .042), and also at increasing the percentage of patients who reported improvement in anxiety and depression symptoms on the Patient Global Impression of Change instrument (P < .001)
An extension study of the durability of the effects at 3 and 6 months is underway.
The investigators noted that the incremental cost of management of anxiety or depression is greater than $17,000 per patient per year.
“One of the big promises of a digital therapeutic like this is that it could potentially reduce costs,” Ms. Ramiller told the audience, but she acknowledged, “More work is really needed, however, to directly test the potential savings.”
The RESTORE study is funded by Blue Note Therapeutics. Dr. Osarogiagbon owns stock in Gilead, Lilly, and Pfizer, has received honoraria from Biodesix and Medscape, and has a consulting or advisory role for the American Cancer Society AstraZeneca, Genentech/Roche, LUNGevity, National Cancer Institute, and Triptych Health Partners.

CHICAGO – One-third of patients with cancer also experience anxiety or depression, and an estimated 70% of the 18 million patients with cancer and cancer survivors in the US experience emotional symptoms, including fear of recurrence.
Despite many having these symptoms, few patients with cancer have access to psycho-oncologic support.
A digital cognitive-behavioral stress management (CBSM) application may help to ease some of the burden, reported Allison Ramiller, MPH, of Blue Note Therapeutics in San Francisco, which developed the app version of the program.
In addition, patients assigned to the CBSM app were twice as likely as control persons to report that their symptoms were “much” or “very much” improved after using the app for 12 weeks, Ms. Ramiller reported at an oral abstract session at the annual meeting of the American Society of Clinical Oncology (ASCO).
However, the investigators did not report baseline characteristics of patients in each of the study arms, which might have helped to clarify the depth of the effects they saw.
The CBSM program was developed by Michael H. Antoni, PhD, and colleagues in the University of Miami Health System. It is based on cognitive-behavioral therapy but also includes stress management and relaxation techniques to help patients cope with cancer-specific stress.
“”It has been clinically validated and shown to benefit patients with cancer,” Ms. Ramiller said. “However, access is a problem,” she said.
“There aren’t enough qualified, trained providers for the need, and patients with cancer encounter barriers to in-person participation, including things like transportation or financial barriers. So to overcome this, we developed a digitized version of CBSM,” she explained.
Impressive and elegant
“Everything about [the study] I thought was very impressive, very elegant, very nicely done,” said invited discussant Raymond U. Osarogiagbon, MBBS, FACP, chief scientist at Baptist Memorial Health Care Corp in Memphis, Tenn.

Huge underuse of germline testing for cancer patients
Information from germline genetic testing could affect a patient’s cancer care. For example, such testing could indicate that targeted therapies would be beneficial, and it would have implications for close relatives who may carry the same genes.
The finding that so few patients with newly diagnosed cancer were tested comes from an analysis of data on more than 1.3 million individuals across two U.S. states. The data were taken from the Surveillance, Epidemiology, and End Results (SEER) registry.
The rate is “well below guideline recommendations,” said study presenter Allison W. Kurian, MD, department of medicine, Stanford (Calif.) University.
“Innovative care delivery” is needed to tackle the problem, including the streamlining of pretest counseling, making posttest counseling more widely available, and employing long-term follow-up to track patient outcomes, she suggested.
“I do think this is a time for creative solutions of a number of different kinds,” she said. She suggested that lessons could be learned from the use of telemedicine during the COVID-19 pandemic. She also noted that “there have been some interesting studies on embedding genetic counselors in oncology clinics.”
Dr. Kurian presented the study at the annual meeting of the American Society of Clinical Oncology (ASCO). The study was simultaneously published in the Journal of the American Medical Association.
The current results represent a “missed opportunity for decrease the population-level burden of cancer,” experts noted in an accompanying editorial.
“Clinicians should recommend testing to their patients and provide them with the information necessary to make informed decisions about whether to undergo testing,” Zsofia K. Stadler, MD, and Deborah Schrag, MD, MPH, of Memorial Sloan Kettering Cancer Center, New York, wrote in their editorial.
They suggested novel approaches to widen access, such as use of point-of-care testing, telecounseling, and, in the future, chatbots to respond to patient questions.
“With greater emphasis on overcoming both health system and patient-level barriers to genetic cancer susceptibility testing for patients with cancer, treatment outcomes will improve and cancer diagnoses and related deaths in family members will be prevented,” they concluded.
At the meeting, invited discussant Erin Frances Cobain, MD, assistant professor of medical oncology, University of Michigan Health, Ann Arbor, referring to breast cancer as an example, said that progress has “stagnated” in recent years.
The study found a higher rate of gene testing among patients with newly diagnosed breast cancer, at just over 20%.
Dr. Cobain argued that this was still too low. She pointed out that “a recent study suggested that over 60% of individuals with an incident cancer diagnosis would meet criteria for genetic testing by National Comprehensive Cancer Network guidelines.
“This may be because testing is not offered, there may be poor access to genetic counseling resources, or patients may be offered testing but decline it,” she suggested.
One compelling reason to conduct genetic testing for patients newly diagnosed with breast cancer is that it may show that they are candidates for treatment with PARP (poly[ADP]-ribose polymerase) inhibitors, which “may have a direct impact on cancer-related mortality,” she pointed out.
“We need increased awareness and access to genetic testing resources for patients with breast cancer, particularly for racial and ethnic minorities,” she said.
Dr. Cobain also noted that finding variants of uncertain significance (VUS) was more likely among patients from racial and ethnic minorities than among White patients. She said such a finding “increases patient and physician anxiety,” and there may be “unclear optimal management recommendations for these patients.”
Details of the study
Germline genetic testing is “increasingly essential for cancer care,” Dr. Kurian said.
It is central to risk-adapted screening and secondary prevention, the use of targeted therapies, including PARP and checkpoint inhibitors, and cascade testing to identify at-risk relatives.
She pointed out that in clinical practice, testing has “evolved rapidly.” Panels include more and more genes. In addition, the cost of these tests is falling, and guidelines have become “more expansive.”
However, “little is known about genetic testing use and results,” Dr. Kurian noted.
The team therefore undertook the SEER-GeneLINK initiative, which involved patients aged ≥ 20 years who were diagnosed with cancer between Jan. 1, 2013, and March 31, 2019, and who were reported to statewide SEER registries in California and Georgia.
The team looked for patients for whom germline genetic test results had been reported by the four laboratories that performed the majority of patient testing in the two states. Results were categorized as pathogenic, benign, or VUS.
The results were classified on the basis of current guidelines for testing and/or management as related to breast/ovarian cancer, gastrointestinal cancer, other hereditary cancers, or those with no guidelines for testing or management.
Dr. Kurian reported that from an overall population of 1,412,388 patients diagnosed with cancer, 1,369,660 were eligible for inclusion. Of those, about half (51.9%) were women, and the majority (86.3%) were aged 50 years or older.
Many of these patients (61.4%) were non-Hispanic White persons, and slightly fewer than half (49.8%) were deemed to be in medium or high poverty, as determined using U.S. Census tract levels.
Overall, germline genetic testing was performed in 93,052 (6.8%) of patients over the study period.
Women were more likely to have undergone germline mutation testing than men, at 13.9% vs. 2.2%, as were patients aged 20-49 years, at 22.1% vs. 8.2% for those aged 50-69 years, and 3.3% for those aged 70 years and older.
The number of genes for which testing was conducted increased from a median of 2 in 2013 to 34 in 2019. Rates of VUS increased more than that for pathologic variants and substantially more so in non-White patients.
By 2019, the ratio of VUS to pathologic variants stood at 1.7 among White patients, vs. 3.9 among Asian patients, 3.6 among Black patients, and 2.2 among Hispanic patients.
The majority of identified pathologic variants that were related to the diagnosed cancer and genes with testing and/or management guidelines accounted for 67.5% to 94.9% of such variants.
Regarding specific cancer diagnoses, Dr. Kurian said that over the course of the study period, testing rates consistently exceeded 50% only among male breast cancer patients.
There were rapid increases in testing for ovarian cancer, from 28.0% of cases in 2013 to 54.0% in 2019. For pancreatic cancer, rates increased from 1.0% to 19.0% over the same period, and for prostate cancer, rates increased from 0.1% to 4.0%. She suggested that these increases in rates may be related to the approval of PARP inhibitors for use in these indications.
However, there was little change in the rates of germline mutation testing for lung cancer patients, from 01% in 2013 to 0.8% in 2019, and for other cancers, from 0.3% to 2.0%.
The results also revealed racial and ethnic differences in testing after controlling for age, cancer type, and year. Over the course of the study period, 8.0% of White patients underwent genetic testing, compared with 6.0% each for Asian, Black, and Hispanic patients and 5.0% for other patients (P < .001).
With regard specifically to male and female breast cancer and ovarian cancer, testing rates were 31% among White patients, 22% for Asian patients, 25% for Black patients, and 23% for Hispanic patients (P < .001).
Dr. Kurian acknowledged that the study is limited by a lack of testing from other laboratories and direct-to-consumer test data, although a recent survey suggested that this represents fewer than 5% of all germline genetic tests.
She also noted that the SEER registries do not collect data on family history or tumor sequencing.
The study was funded by the National Institutes of Health, and the Centers for Disease Control and Prevention. Dr. Kurian has relationships with Adela, Ambry Genetics, Color Genomics, GeneDx/BioReference, Genentech, InVitae, and Myriad Genetics. Other authors report numerous relationships with industry. Dr. Cobain has ties with AstraZeneca, Daiichi Sankyo, Athenex, Ayala Pharmaceuticals, bioTheranostics, and Immunomedics. Dr. Schrag has relationships with Merck, JAMA, AACR, and Grail. Dr. Stadler has ties with Adverum Biotechnologies, Genentech, Neurogene, Novartis, Optos Plc, Outlook Therapeutics, and Regeneron Pharmaceuticals.

Dr. Kurian reported that from an overall population of 1,412,388 patients diagnosed with cancer, 1,369,660 were eligible for inclusion. Of those, about half (51.9%) were women, and the majority (86.3%) were aged 50 years or older.
Many of these patients (61.4%) were non-Hispanic White persons, and slightly fewer than half (49.8%) were deemed to be in medium or high poverty, as determined using U.S. Census tract levels.
Overall, germline genetic testing was performed in 93,052 (6.8%) of patients over the study period.
Women were more likely to have undergone germline mutation testing than men, at 13.9% vs. 2.2%, as were patients aged 20-49 years, at 22.1% vs. 8.2% for those aged 50-69 years, and 3.3% for those aged 70 years and older.
The number of genes for which testing was conducted increased from a median of 2 in 2013 to 34 in 2019. Rates of VUS increased more than that for pathologic variants and substantially more so in non-White patients.
By 2019, the ratio of VUS to pathologic variants stood at 1.7 among White patients, vs. 3.9 among Asian patients, 3.6 among Black patients, and 2.2 among Hispanic patients.
The majority of identified pathologic variants that were related to the diagnosed cancer and genes with testing and/or management guidelines accounted for 67.5% to 94.9% of such variants.
Regarding specific cancer diagnoses, Dr. Kurian said that over the course of the study period, testing rates consistently exceeded 50% only among male breast cancer patients.
There were rapid increases in testing for ovarian cancer, from 28.0% of cases in 2013 to 54.0% in 2019. For pancreatic cancer, rates increased from 1.0% to 19.0% over the same period, and for prostate cancer, rates increased from 0.1% to 4.0%. She suggested that these increases in rates may be related to the approval of PARP inhibitors for use in these indications.
However, there was little change in the rates of germline mutation testing for lung cancer patients, from 01% in 2013 to 0.8% in 2019, and for other cancers, from 0.3% to 2.0%.
The results also revealed racial and ethnic differences in testing after controlling for age, cancer type, and year. Over the course of the study period, 8.0% of White patients underwent genetic testing, compared with 6.0% each for Asian, Black, and Hispanic patients and 5.0% for other patients (P < .001).
With regard specifically to male and female breast cancer and ovarian cancer, testing rates were 31% among White patients, 22% for Asian patients, 25% for Black patients, and 23% for Hispanic patients (P < .001).
Dr. Kurian acknowledged that the study is limited by a lack of testing from other laboratories and direct-to-consumer test data, although a recent survey suggested that this represents fewer than 5% of all germline genetic tests.
She also noted that the SEER registries do not collect data on family history or tumor sequencing.
The study was funded by the National Institutes of Health, and the Centers for Disease Control and Prevention. Dr. Kurian has relationships with Adela, Ambry Genetics, Color Genomics, GeneDx/BioReference, Genentech, InVitae, and Myriad Genetics. Other authors report numerous relationships with industry. Dr. Cobain has ties with AstraZeneca, Daiichi Sankyo, Athenex, Ayala Pharmaceuticals, bioTheranostics, and Immunomedics. Dr. Schrag has relationships with Merck, JAMA, AACR, and Grail.

AT ASCO 2023
DEI training gives oncology fellows more confidence
The finding comes from a survey conducted after the introduction of DEI training within the Yale Medical Oncology-Hematology Fellowship Program. The study was reported by Norin Ansari, MD, MPH, of Yale Cancer Center, New Haven, Conn., at the annual meeting of the American Society of Clinical Oncology (ASCO).
Dr. Ansari emphasized the DEI curriculum in fellowship programs by highlighting the racial and gender disparities that exist among physicians.
“There is a significant representation problem – only 2%-3% of practicing oncologists are Black or Hispanic/Latino,” she said. “And that representation decreases with each stage in the pipeline of the workforce.”
Dr. Ansari also noted gender disparities in the oncologist workforce, reporting that about one-third of faculty positions are held by women.
The anonymous survey was sent to 29 fellows; 23 responded, including 8 first-year fellows and 13 senior fellows. Over 57% of respondents rated the importance of DEI education as 10 on a 10-point scale (mean, 8.6).
At the start of this year, the responses of senior fellows who had already received some DEI training during the previous year’s lecture series were compared with first-year fellows who had not had any fellowship DEI education.
First-year fellows reported a mean confidence score of 2.5/5 at navigating bias and microaggressions when experienced personally and a mean score of 2.9/5 when they were directed at others. Senior fellows reported mean confidence scores of 3 and 3.2, respectively.
Yale then compared longitudinal data on fellows’ comfort levels in navigating discrimination in 2021, 2022, and 2023 a month before the ASCO meeting.
Fellows were asked to rate their comfort level from 1 to 10 in navigating different types of discrimination, including racial inequality, sexual harassment, and gender discrimination. In these three categories, fellows rated comfortability as a 5 in 2021 and as 7 in 2023 after the DEI training.
“Our first goal is to normalize talking about DEI and to recognize that different people in our workforce have different experiences and how we can be allies for them and for our patients,” Dr. Ansari said. “And I think for long-term goals we want to take stock of who’s at the table, who’s making decisions, and how does that affect our field, our science, and our patients.”
Yale designed the 3-year longitudinal curriculum with two annual core topics: upstander training and journal club for discussion and reflection. An additional two to three training sessions per year will focus on either race, gender, LGBTQ+, disability, religion, or implicit bias training.
The most popular topics among fellows were upstander training, cancer treatment and outcomes disparities, recruitment and retention, and career promotion and pay disparities.
The preferred platforms of content delivery were lectures from experts in the field, affinity groups or mentorship links, small group discussions, and advocacy education.
Gerald Hsu, MD, PhD, with the San Francisco VA Medical Center, discussed the results of Yale’s DEI curriculum assessment, saying it represented “best practices” in the industry. However, he acknowledged that realistically, not everyone will be receptive to DEI training.
Dr. Hsu said that holding medical staff accountable is the only way to truly incorporate DEI into everyday practice.
“Collectively, we need to be holding ourselves to different standards or holding ourselves to some standard,” Dr. Hsu said. “Maybe we need to be setting goals to the degree to which we diversify our training programs and our faculty, and there needs to be consequences to not doing so.”
No funding for the study was reported.

FROM ASCO 2023
Drugmakers are abandoning cheap generics, and now U.S. cancer patients can’t get meds
On Nov. 22, three Food and Drug Administration inspectors arrived at the sprawling Intas Pharmaceuticals plant south of Ahmedabad, India, and found hundreds of trash bags full of shredded documents tossed into a garbage truck. Over the next 10 days, the inspectors assessed what looked like a systematic effort to conceal quality problems at the plant, which provided more than half of the U.S. supply of generic cisplatin and carboplatin, two cheap drugs used to treat as many as 500,000 new cancer cases every year.
Their decisions are likely to result in preventable deaths.
Cisplatin and carboplatin are among scores of drugs in shortage, including 12 other cancer drugs, ADHD pills, blood thinners, and antibiotics. COVID-hangover supply chain issues and limited FDA oversight are part of the problem, but the main cause, experts agree, is the underlying weakness of the generic drug industry. Made mostly overseas, these old but crucial drugs are often sold at a loss or for little profit. Domestic manufacturers have little interest in making them, setting their sights instead on high-priced drugs with plump profit margins.
The problem isn’t new, and that’s particularly infuriating to many clinicians. President Joe Biden, whose son Beau died of an aggressive brain cancer, has focused his Cancer Moonshot on discovering cures – undoubtedly expensive ones. Indeed, existing brand-name cancer drugs often cost tens of thousands of dollars a year.
But what about the thousands of patients today who can’t get a drug like cisplatin, approved by the FDA in 1978 and costing as little as $6 a dose?
“It’s just insane,” said Mark Ratain, MD, a cancer doctor and pharmacologist at the University of Chicago. “Your roof is caving in, but you want to build a basketball court in the backyard because your wife is pregnant with twin boys and you want them to be NBA stars when they grow up?”
“It’s just a travesty that this is the level of health care in the United States of America right now,” said Stephen Divers, MD, an oncologist in Hot Springs, Ark., who in recent weeks has had to delay or change treatment for numerous bladder, breast, and ovarian cancer patients because his clinic cannot find enough cisplatin and carboplatin. Results from a survey of academic cancer centers released June 7 found 93% couldn’t find enough carboplatin and 70% had cisplatin shortages.
“All day, in between patients, we hold staff meetings trying to figure this out,” said Bonny Moore, MD, an oncologist in Fredericksburg, Virginia. “It’s the most nauseous I’ve ever felt. Our office stayed open during COVID; we never had to stop treating patients. We got them vaccinated, kept them safe, and now I can’t get them a $10 drug.”
The cancer clinicians KFF Health News interviewed for this story said that, given current shortages, they prioritize patients who can be cured over later-stage patients, in whom the drugs generally can only slow the disease, and for whom alternatives – though sometimes less effective and often with more side effects – are available. But some doctors are even rationing doses intended to cure.
Isabella McDonald, then a junior at Utah Valley University, was diagnosed in April with a rare, often fatal bone cancer, whose sole treatment for young adults includes the drug methotrexate. When Isabella’s second cycle of treatment began June 5, clinicians advised that she would be getting less than the full dose because of a methotrexate shortage, said her father, Brent.
“They don’t think it will have a negative impact on her treatment, but as far as I am aware, there isn’t any scientific basis to make that conclusion,” he said. “As you can imagine, when they gave us such low odds of her beating this cancer, it feels like we want to give it everything we can and not something short of the standard.”
Mr. McDonald stressed that he didn’t blame the staffers at Intermountain Health who take care of Isabella. The family – his other daughter, Cate, made a TikTok video about her sister’s plight – were simply stunned at such a basic flaw in the health care system.
At Dr. Moore’s practice, in Virginia, clinicians gave 60% of the optimal dose of carboplatin to some uterine cancer patients during the week of May 16, then shifted to 80% after a small shipment came in the following week. The doctors had to omit carboplatin from normal combination treatments for patients with recurrent disease, she said.
On June 2, Dr. Moore and colleagues were glued to their drug distributor’s website, anxious as teenagers waiting for Taylor Swift tickets to go on sale – only with mortal consequences at stake.
She later emailed KFF Health News: “Carboplatin did NOT come back in stock today. Neither did cisplatin.”
Doses remained at 80%, she said. Things hadn’t changed 10 days later.
Generics manufacturers are pulling out
The causes of shortages are well established. Everyone wants to pay less, and the middlemen who procure and distribute generics keep driving down wholesale prices. The average net price of generic drugs fell by more than half between 2016 and 2022, according to research by Anthony Sardella, a business professor at Washington University in St. Louis.
As generics manufacturers compete to win sales contracts with the big negotiators of such purchases, such as Vizient and Premier, their profits sink. Some are going out of business. Akorn, which made 75 common generics, went bankrupt and closed in February. Israeli generics giant Teva, which has a portfolio of 3,600 medicines, announced May 18 it was shifting to brand-name drugs and “high-value generics.” Lannett, with about 120 generics, announced a Chapter 11 reorganization amid declining revenue. Other companies are in trouble too, said David Gaugh, interim CEO of the Association for Accessible Medicines, the leading generics trade group.
The generics industry used to lose money on about a third of the drugs it produced, but now it’s more like half, Mr. Gaugh said. So when a company stops making a drug, others do not necessarily step up, he said. Officials at Fresenius Kabi and Pfizer said they have increased their carboplatin production since March, but not enough to end the shortage. On June 2, FDA Commissioner Robert Califf announced the agency had given emergency authorization for Chinese-made cisplatin to enter the U.S. market, but the impact of the move wasn’t immediately clear.
Cisplatin and carboplatin are made in special production lines under sterile conditions, and expanding or changing the lines requires FDA approval. Bargain-basement prices have pushed production overseas, where it’s harder for the FDA to track quality standards. The Intas plant inspection was a relative rarity in India, where the FDA in 2022 reportedly inspected only 3% of sites that make drugs for the U.S. market. Mr. Sardella testified in May that a quarter of all U.S. drug prescriptions are filled by companies that received FDA warning letters in the past 26 months. And pharmaceutical industry product recalls are at their highest level in 18 years, reflecting fragile supply conditions.
The FDA listed 137 drugs in shortage as of June 13, including many essential medicines made by few companies.
Intas voluntarily shut down its Ahmedabad plant after the FDA inspection, and the agency posted its shocking inspection report in January. Accord Healthcare, the U.S. subsidiary of Intas, said in mid-June it had no date for restarting production.
Asked why it waited 2 months after its inspection to announce the cisplatin shortage, given that Intas supplied more than half the U.S. market for the drug, the FDA said via email that it doesn’t list a drug in shortage until it has “confirmed that overall market demand is not being met.”
Prices for carboplatin, cisplatin, and other drugs have skyrocketed on the so-called gray market, where speculators sell medicines they snapped up in anticipation of shortages. A 600-mg bottle of carboplatin, normally available for $30, was going for $185 in early May and $345 a week later, said Richard Scanlon, the pharmacist at dr. Moore’s clinic.
“It’s hard to have these conversations with patients – ‘I have your dose for this cycle, but not sure about next cycle,’” said Mark Einstein, MD, chair of the department of obstetrics, gynecology and reproductive health at New Jersey Medical School, Newark.
Should government step in?
Despite a drug shortage task force and numerous congressional hearings, progress has been slow at best. The 2020 CARES Act gave the FDA the power to require companies to have contingency plans enabling them to respond to shortages, but the agency has not yet implemented guidance to enforce the provisions.
As a result, neither Accord nor other cisplatin makers had a response plan in place when Intas’ plant was shut down, said Soumi Saha, senior vice president of government affairs for Premier, which arranges wholesale drug purchases for more than 4,400 hospitals and health systems.
Premier understood in December that the shutdown endangered the U.S. supply of cisplatin and carboplatin, but it also didn’t issue an immediate alarm. “It’s a fine balance,” she said. “You don’t want to create panic-buying or hoarding.”
More lasting solutions are under discussion. Mr. Sardella and others have proposed government subsidies to get U.S. generics plants running full time. Their capacity is now half-idle. If federal agencies like the Centers for Medicare & Medicaid Services paid more for more safely and efficiently produced drugs, it would promote a more stable supply chain, he said.
“At a certain point the system needs to recognize there’s a high cost to low-cost drugs,” said Allan Coukell, senior vice president for public policy at Civica Rx, a nonprofit funded by health systems, foundations, and the federal government that provides about 80 drugs to hospitals in its network. Civica is building a $140 million factory near Petersburg, Va., that will produce dozens more, Mr. Coukell said.
Dr. Ratain and his University of Chicago colleague Satyajit Kosuri, MD, recently called for the creation of a strategic inventory buffer for generic medications, something like the Strategic Petroleum Reserve, set up in 1975 in response to the OPEC oil crisis.
In fact, Dr. Ratain reckons, selling a quarter-million barrels of oil would probably generate enough cash to make and store 2 years’ worth of carboplatin and cisplatin.
“It would almost literally be a drop in the bucket.”

If federal agencies like the Centers for Medicare & Medicaid Services paid more for more safely and efficiently produced drugs, it would promote a more stable supply chain, he said.
“At a certain point the system needs to recognize there’s a high cost to low-cost drugs,” said Allan Coukell, senior vice president for public policy at Civica Rx, a nonprofit funded by health systems, foundations, and the federal government that provides about 80 drugs to hospitals in its network. Civica is building a $140 million factory near Petersburg, Va., that will produce dozens more, Mr. Coukell said.
Dr. Ratain and his University of Chicago colleague Satyajit Kosuri, MD, recently called for the creation of a strategic inventory buffer for generic medications, something like the Strategic Petroleum Reserve, set up in 1975 in response to the OPEC oil crisis.
In fact, Dr. Ratain reckons, selling a quarter-million barrels of oil would probably generate enough cash to make and store 2 years’ worth of carboplatin and cisplatin.
“It would almost literally be a drop in the bucket.”

On Nov. 22, three Food and Drug Administration inspectors arrived at the sprawling Intas Pharmaceuticals plant south of Ahmedabad, India, and found hundreds of trash bags full of shredded documents tossed into a garbage truck. Over the next 10 days, the inspectors assessed what looked like a systematic effort to conceal quality problems at the plant, which provided more than half of the U.S. supply of generic cisplatin and carboplatin, two cheap drugs used to treat as many as 500,000 new cancer cases every year.
Their decisions are likely to result in preventable deaths.
Cisplatin and carboplatin are among scores of drugs in shortage, including 12 other cancer drugs, ADHD pills, blood thinners, and antibiotics. COVID-hangover supply chain issues and limited FDA oversight are part of the problem, but the main cause, experts agree, is the underlying weakness of the generic drug industry. Made mostly overseas, these old but crucial drugs are often sold at a loss or for little profit. Domestic manufacturers have little interest in making them, setting their sights instead on high-priced drugs with plump profit margins.
The problem isn’t new, and that’s particularly infuriating to many clinicians. President Joe Biden, whose son Beau died of an aggressive brain cancer, has focused his Cancer Moonshot on discovering cures – undoubtedly expensive ones. Indeed, existing brand-name cancer drugs often cost tens of thousands of dollars a year.
But what about the thousands of patients today who can’t get a drug like cisplatin, approved by the FDA in 1978 and costing as little as $6 a dose?
“It’s just insane,” said Mark Ratain, MD, a cancer doctor and pharmacologist at the University of Chicago. “Your roof is caving in, but you want to build a basketball court in the backyard because your wife is pregnant with twin boys and you want them to be NBA stars when they grow up?”
“It’s just a travesty that this is the level of health care in the United States of America right now,” said Stephen Divers, MD, an oncologist in Hot Springs, Ark., who in recent weeks has had to delay or change treatment for numerous bladder, breast, and ovarian cancer patients because his clinic cannot find enough cisplatin and carboplatin. Results from a survey of academic cancer centers released June 7 found 93% couldn’t find enough carboplatin and 70% had cisplatin shortages.
“All day, in between patients, we hold staff meetings trying to figure this out,” said Bonny Moore, MD, an oncologist in Fredericksburg, Virginia. “It’s the most nauseous I’ve ever felt. Our office stayed open during COVID; we never had to stop treating patients. We got them vaccinated, kept them safe, and now I can’t get them a $10 drug.”
The cancer clinicians KFF Health News interviewed for this story said that, given current shortages, they prioritize patients who can be cured over later-stage patients, in whom the drugs generally can only slow the disease, and for whom alternatives – though sometimes less effective and often with more side effects – are available. But some doctors are even rationing doses intended to cure.
Isabella McDonald, then a junior at Utah Valley University, was diagnosed in April with a rare, often fatal bone cancer, whose sole treatment for young adults includes the drug methotrexate. When Isabella’s second cycle of treatment began June 5, clinicians advised that she would be getting less than the full dose because of a methotrexate shortage, said her father, Brent.
“They don’t think it will have a negative impact on her treatment, but as far as I am aware, there isn’t any scientific basis to make that conclusion,” he said. “As you can imagine, when they gave us such low odds of her beating this cancer, it feels like we want to give it everything we can and not something short of the standard.”
Mr. McDonald stressed that he didn’t blame the staffers at Intermountain Health who take care of Isabella. The family – his other daughter, Cate, made a TikTok video about her sister’s plight – were simply stunned at such a basic flaw in the health care system.
At Dr. Moore’s practice, in Virginia, clinicians gave 60% of the optimal dose of carboplatin to some uterine cancer patients during the week of May 16, then shifted to 80% after a small shipment came in the following week. The doctors had to omit carboplatin from normal combination treatments for patients with recurrent disease, she said.
On June 2, Dr. Moore and colleagues were glued to their drug distributor’s website, anxious as teenagers waiting for Taylor Swift tickets to go on sale – only with mortal consequences at stake.
She later emailed KFF Health News: “Carboplatin did NOT come back in stock today. Neither did cisplatin.”
Doses remained at 80%, she said. Things hadn’t changed 10 days later.
Generics manufacturers are pulling out
The causes of shortages are well established. Everyone wants to pay less, and the middlemen who procure and distribute generics keep driving down wholesale prices. The average net price of generic drugs fell by more than half between 2016 and 2022, according to research by Anthony Sardella, a business professor at Washington University in St. Louis.
As generics manufacturers compete to win sales contracts with the big negotiators of such purchases, such as Vizient and Premier, their profits sink. Some are going out of business. Akorn, which made 75 common generics, went bankrupt and closed in February. Israeli generics giant Teva, which has a portfolio of 3,600 medicines, announced May 18 it was shifting to brand-name drugs and “high-value generics.” Lannett, with about 120 generics, announced a Chapter 11 reorganization amid declining revenue. Other companies are in trouble too, said David Gaugh, interim CEO of the Association for Accessible Medicines, the leading generics trade group.
The generics industry used to lose money on about a third of the drugs it produced, but now it’s more like half, Mr. Gaugh said. So when a company stops making a drug, others do not necessarily step up, he said. Officials at Fresenius Kabi and Pfizer said they have increased their carboplatin production since March, but not enough to end the shortage. On June 2, FDA Commissioner Robert Califf announced the agency had given emergency authorization for Chinese-made cisplatin to enter the U.S. market, but the impact of the move wasn’t immediately clear.
Cisplatin and carboplatin are made in special production lines under sterile conditions, and expanding or changing the lines requires FDA approval. Bargain-basement prices have pushed production overseas, where it’s harder for the FDA to track quality standards. The Intas plant inspection was a relative rarity in India, where the FDA in 2022 reportedly inspected only 3% of sites that make drugs for the U.S. market. Mr. Sardella testified in May that a quarter of all U.S. drug prescriptions are filled by companies that received FDA warning letters in the past 26 months. And pharmaceutical industry product recalls are at their highest level in 18 years, reflecting fragile supply conditions.
The FDA listed 137 drugs in shortage as of June 13, including many essential medicines made by few companies.
Intas voluntarily shut down its Ahmedabad plant after the FDA inspection, and the agency posted its shocking inspection report in January. Accord Healthcare, the U.S. subsidiary of Intas, said in mid-June it had no date for restarting production.
Asked why it waited 2 months after its inspection to announce the cisplatin shortage, given that Intas supplied more than half the U.S. market for the drug, the FDA said via email that it doesn’t list a drug in shortage until it has “confirmed that overall market demand is not being met.”
Prices for carboplatin, cisplatin, and other drugs have skyrocketed on the so-called gray market, where speculators sell medicines they snapped up in anticipation of shortages. A 600-mg bottle of carboplatin, normally available for $30, was going for $185 in early May and $345 a week later, said Richard Scanlon, the pharmacist at dr. Moore’s clinic.
“It’s hard to have these conversations with patients – ‘I have your dose for this cycle, but not sure about next cycle,’” said Mark Einstein, MD, chair of the department of obstetrics, gynecology and reproductive health at New Jersey Medical School, Newark.
Should government step in?
Despite a drug shortage task force and numerous congressional hearings, progress has been slow at best. The 2020 CARES Act gave the FDA the power to require companies to have contingency plans enabling them to respond to shortages, but the agency has not yet implemented guidance to enforce the provisions.
As a result, neither Accord nor other cisplatin makers had a response plan in place when Intas’ plant was shut down, said Soumi Saha, senior vice president of government affairs for Premier, which arranges wholesale drug purchases for more than 4,400 hospitals and health systems.
Premier understood in December that the shutdown endangered the U.S. supply of cisplatin and carboplatin, but it also didn’t issue an immediate alarm. “It’s a fine balance,” she said. “You don’t want to create panic-buying or hoarding.”
More lasting solutions are under discussion. Mr. Sardella and others have proposed government subsidies to get U.S. generics plants running full time. Their capacity is now half-idle.
