Lung Cancer

SAN DIEGO — Chimeric antigen receptor (CAR) T-cell therapies offer the tantalizing prospect of dramatically altering the outcome of lung cancers, but there are many hurdles to treating patients with them, according to experts.

These hurdles include finding the right targets, minimizing the risks of the treatment, and reducing the enormous burdens getting these therapies places on patients.

“Precision immunotherapy,” or unleashing the immune system in a highly specific manner, “is obviously, in a way, a holy grail” in lung cancer, said Martin Forster, MD, PhD, who cochaired a session on the topic at the World Conference on Lung Cancer (WCLC) 2024.

He underlined, however, that “immunology is very complex, as is cancer biology,” and consequently, there are different avenues being explored, including CAR T-cell therapies, T-cell receptor therapies, and tumor-infiltrating lymphocytes, among others.

Antibody technology is also being harnessed to target chemotherapy, via antibody-drug conjugates, noted Forster, who is clinical lead of the early phase clinical trials programme at University College London in England.

Moreover, investigators are looking at combining various therapies, such as immune checkpoint inhibitors with T cell–engaging approaches.

He highlighted, however, that the ideal target for these approaches is something that is recognized by the immune system as being foreign, but is found within the cancer, “and you also want it ideally to be in all of the cancer cells.”

A good example is a clonal change, meaning an early evolutionary genetic alteration in the tumor that is present in all the cells, Forster said.
 

Identifying the Right Target

“One of the big challenges in all forms of targeted immunotherapy is around selecting the target and developing the right product for the right target,” Forster emphasized.

“This concept works really well in hematological malignancies” but is “proving to be more challenging to deliver within solid malignancies,” he added.

“The reason why so many lung tumors are resistant to immunotherapy is because they ‘re immunologically cold,” Roy Herbst, MD, PhD, Department of Medical Oncology, Yale Comprehensive Cancer Center, New Haven, Connecticut, said in an interview.

“There are no T cells in the tumor,” he explained, so it “doesn’t really matter how much you block checkpoint inhibitors, you still have to have a T cell in there in order to have effect.”

To overcome this problem CAR T-cell therapies are engineered to target a tumor, Herbst continued, but that “is a little hard in lung cancer because you need to have a unique antigen that’s on a lung tumor that’s not present on normal cells.”

Charu Aggarwal, MD, MPH, Leslye M. Heisler Associate Professor for Lung Cancer Excellence, Penn Medicine, Philadelphia, Pennsylvania, agreed, saying that there is “a lot of excitement with CAR T-cell therapies, and the promise of cure,” but “the biology is not as simple as we think.”

“For example, it’s not as simple as CD20 or CD19 targeting,” she said in an interview. “Most of the antigens that are being targeted in the solid tumor world, unfortunately, are also expressed on normal tissue. So there is always this potential for toxicity.”
 

A Question of Time

Another aspect of CAR T-cell therapy that is proving difficult is its delivery.

Forster outlined that the process involves first leukapheresis, in which T cells are obtained from a blood draw. These are then genetically modified to express chimeric antigen receptors before being multiplied in the laboratory and introduced to the patient.

This process can take several weeks, during which patients may require bridging treatment, such as chemotherapy or radiotherapy, to keep their cancer under control. “Sometimes, patients with solid tumors who are in later lines of therapy may not have the luxury of time to be able to wait for all of these steps,” Aggarwal said.

There is also the question of whether a bespoke treatment can be scaled up so that it can be delivered to more patients in a more timely manner.

“There are certainly lessons to be learned from use of off-the-shelf CAR T-cell products” in hematologic malignancies, she noted, “but we’re just not there yet in lung cancer.”
 

Life-Threatening Toxicities

To improve the chances of engraftment when the CAR T cells are introduced, patients will require prior lymphodepletion with chemotherapy.

This, Forster said, is a “relatively intensive part of treatment.” However, “if you just give immune cells to somebody, when the host body is already full of immune cells,” the CAR T cells are unlikely to engraft, and “so you need to create space for those cells to develop.”

“What you want is not an immediate effect” but rather an immune “memory” that will give an ongoing benefit, he underscored.

Many patients will need to stay in the hospital one or more nights “because when you bring T cells to a tumor, you get cytokine release syndrome [CRS],” Herbst said. This can cause hypotension, fever, and chills, similar to a viral response.

“So patients can get sick,” which in turn requires treatment and follow-up. That puts a “big burden on the health system” and is a major issue, Herbst said.

Patients are also at a risk for “significant neurotoxicity,” said session cochair Amy Moore, PhD, vice president of Global Engagement and Patient Partnerships, LUNGevity Foundation, Chicago. This, alongside CRS, “can be life threatening for our patients.”

Lengthy hospital stays also have a psychosocial impact on the patient and their quality of life, she emphasized, especially when they are treated in a center far away from family and loved ones.

“We’ve also heard anecdotally some reports recently of secondary malignancies” with CAR T cell and other therapies, and that’s something that needs to be monitored as more patients go on these treatments, she said.
 

‘At What Cost’ to Patients?

The difficulties faced by patients in receiving CAR T-cell therapy go far beyond the practicalities of generating the cells or the risks associated with lymphodepletion, however.

“These therapies are extraordinarily expensive,” although that has to be weighed against the cost of years of ongoing treatment with immunotherapy, Moore said.

Moreover, as CAR T-cell therapies are a “last resort” option, patients have to “exhaust all other treatments” before being eligible, she continued. There’s significant prior authorization challenges, which means patients “have to go through many hurdles before they can qualify for treatment with these therapies.”

This typically involves having numerous laboratory tests, which can add up to out-of-pocket expenses for patients often reaching tens of thousands of dollars, Moore said.

Another issue is that they must be administered in certified treatment centers, and there are a limited number of those in the United States, she added.

This increases the risk of heightening disparities, as patients are “forced to travel, seek lodging, and have meal expenses,” and the costs “are not trivial,” Moore underlined. “It can rack up quickly and mount to $10,000 or more.”

For physicians, there are difficulties in terms of the logistics of following up with those patients who need to be treated at centers on the other side of the country, uncertainties around reimbursement, and restrictions in terms of staff time and resources, among others.

“I’m as excited as you are at the science,” but it is the implementation that is at issue, Moore said. In other words, there is the offer of a cure with CAR T-cell therapy, but “at what cost?”

“For patients, these considerations are real and they’re significant” and “we have to ensure that what we’re doing is in service of people with cancer,” she emphasized.

No funding was declared. Aggarwal declared relationships with Genentech, Celgene, AstraZeneca, Daiichi Sankyo, Turning Point, Janssen, Pfizer, Lilly, Merck, Regeneron/Sanofi, Eisai, BeiGene, Boehringer Ingelheim, Blueprint Genetics, and Shionogi. Forster declared relationships with AstraZeneca, Boehringer Ingelheim, Merck, MSD, Achilles, Amgen, Bayer, Bristol-Myers Squibb, Celgene, EQRx, GSK, Immutep, Janssen, Merck, Oxford Vacmedix, PharmaMar, Roche, Takeda, Syncorp, Transgene, and Ultrahuman. Moore declared no relevant financial relationships.

Fantine Giap, MD, sat across from a 21-year-old with a rare sarcoma at the base of her skull. 

Despite the large tumor, nestled in a sensitive area, the Boston-based radiation oncologist could envision a bright future for her patient. 

She and the other members of the patient’s care team had an impressive cancer-fighting arsenal at her fingertips. The team had recommended surgery, followed by proton therapy — a sophisticated tool able to deliver concentrated, razor-focused radiation to the once apple-sized growth, while sparing the fragile brain stem, optic nerve, and spinal cord. 

Surgery went as planned. But as the days and weeks wore on and insurance prior authorization for the proton therapy never came, the tumor roared back, leading to more surgeries and more complications. Ultimately, the young woman needed a tracheostomy and a feeding tube. 

By the time insurance said yes, more than 1 year from her initial visit, the future the team had envisioned seemed out of reach. 

“Unfortunately for this patient, it went from a potentially curable situation to a likely not curable situation,” recalled Dr. Giap, a clinician at Massachusetts General Hospital and instructor at Harvard Medical School, Boston. “I wanted to cry every day that she waited.’’ 

While a stark example, such insurance delays are not uncommon, according to new research published in JAMA Network Open.

The study of 206 denials in radiation oncology concluded that more than two-thirds were ultimately approved on appeal without changes, but often these approvals came only after costly delays that potentially compromised patient care.

Other studies have found that number to be even higher, with more than 86% of prior authorization requests ultimately approved with few changes.

‘’It gives you the idea that this entire process might be a little futile — that it’s just wasting people’s time,’’ said Fumiko Chino, MD, coauthor on the JAMA study and now an assistant professor in radiation oncology at MD Anderson Cancer Center in Houston. ‘’The problem is cancer doesn’t wait for bureaucracy.’’
 

Barriers at Every Step

As Dr. Chino and her study coauthors explained, advancements like intensity-modulated radiation therapy and stereotactic radiosurgery have allowed a new generation of specialists to treat previously untreatable cancers in ways that maximize tumor-killing power while minimizing collateral damage. But these tools require sophisticated planning, imaging, simulations and execution — all of which are subject to increased insurance scrutiny.

‘’We face barriers pretty much every step of the way for every patient,’’ said Dr. Chino.

To investigate how such barriers impact care, Dr. Chino and colleagues at Memorial Sloan Kettering Cancer Center — where she worked until July — looked at 206 cases in which payers denied prior authorization for radiation therapy from November 1, 2021 to December 8, 2022. 

The team found that 62% were ultimately approved without any change to technique or dose, while 28% were authorized, but with lower doses or less sophisticated techniques. Four people, however, never got authorization at all — three abandoned treatment altogether, and one sought treatment at another institution.

Treatment delays ranged from 1 day to 49 days. Eighty-three patients died.

Would some of them have lived if it weren’t for prior authorization?

Dr. Chino cannot say for sure, but did note that certain cancers, like cervical cancer, can grow so quickly that every day of delayed treatment makes them harder to control. 

Patients with metastatic or late-stage cancers are often denied more aggressive treatments by insurers who, in essence, “assume that they are going to die from their disease anyway,” Dr. Chino said. 

She views this as tragically shortsighted.

‘’There’s actually a strong body of evidence to show that if you treat even metastatic stage IV diseases aggressively, you can prolong not just quality of life but also quantity,’’ she said. 

In cases where the cancer is more localized and insurance mandates lower doses or cheaper techniques, the consequences can be equally heartbreaking.

‘’It’s like saying instead of taking an extra-strength Tylenol you can only have a baby aspirin,’’ she said. ‘’Their pain is less likely to be controlled, their disease is less likely to be controlled, and they are more likely to need retreatment.’’

Prior authorization delays can also significantly stress patients at the most vulnerable point of their lives.

In another recent study, Dr. Chino found that 69% of patients with cancer reported prior authorization-related delays in care, with one-third waiting a month or longer. One in five never got the care their doctors recommended, and 20% reported spending more than 11 hours on the phone haggling with their insurance companies. 

Most patients rated the process as ‘’bad’’ or ‘’horrible,’’ and said it fueled anxiety.

Such delays can be hard on clinicians and the healthcare system too. 

One 2022 study found that a typical academic radiation oncology practice spent about a half-million dollars per year seeking insurance preauthorization. Nationally, that number exceeds $40 million.

Then there is the burnout factor. 

Dr. Giap, an early-career physician who specializes in rare, aggressive sarcomas, works at an institution that helped pioneer proton therapy. She says it pains her to tell a desperate patient, like the 21-year-old, who has traveled to her from out of state that they have to wait. 

‘’Knowing that the majority of the cases are ultimately approved and that this wait is often unnecessary makes it even tougher,’’ she said.

Dr. Chino, a breast cancer specialist, has taken to warning patients before the alarming insurance letter arrives in the mail that their insurance may delay authorizing their care. But she tells patients that she will do everything she can to fight for them and develops a back-up plan to pivot to quickly, if needed.

‘’No one goes into medicine to spend their time talking to insurance companies,’’ said Dr. Chino.

The national trade group, America’s Health Insurance Plans (AHIP), did not return repeated requests for an interview for this story. But their official position, as stated on their website, is that “prior authorization is one of many tools health insurance providers use to promote safe, timely, evidence-based, affordable, and efficient care.”

Both Dr. Giap and Dr. Chino believe that prior authorization was developed with good intentions: to save healthcare costs and rein in treatments that don’t necessarily benefit patients. 

But, in their specialty, the burden has proliferated to a point that Dr. Chino characterizes as ‘’unconscionable.’’

She believes that policy changes like the proposed Improving Seniors’ Timely Access to Care Act — which would require real-time decisions for procedures that are routinely approved — could go a long way in improving patient care.

Meanwhile, Dr. Giap said, more research and professional guidelines are necessary to bolster insurance company confidence in newer technologies, particularly for rare cancers.

Her patient ultimately got her proton therapy and is ‘’doing relatively well, all things considered.’’

But not all the stories end like this.

Dr. Chino will never forget a patient with a cancer growing so rapidly she could see it protruding through her chest wall. She called for an urgent PET scan to see where else in the body the cancer might be brewing and rushed the planning process for radiation therapy, both of which faced prior authorization barriers. That scan — which ultimately showed the cancer had spread — was delayed for months.*

If the team had had those imaging results upfront, she said, they would have recommended a completely different course of treatment.

And her patient might be alive today.

‘’Unfortunately,” Dr. Chino said, “the people with the very worst prior authorization stories aren’t here anymore to tell you about them.”

*Correction,  10/4/24: An earlier version of this article erroneously stated that Dr. Chino called for surgery for her patient. She actually called for a PET scan and an urgent radiation start.

‘’It’s like saying instead of taking an extra-strength Tylenol you can only have a baby aspirin,’’ she said. ‘’Their pain is less likely to be controlled, their disease is less likely to be controlled, and they are more likely to need retreatment.’’

Prior authorization delays can also significantly stress patients at the most vulnerable point of their lives.

In another recent study, Dr. Chino found that 69% of patients with cancer reported prior authorization-related delays in care, with one-third waiting a month or longer. One in five never got the care their doctors recommended, and 20% reported spending more than 11 hours on the phone haggling with their insurance companies. 

Most patients rated the process as ‘’bad’’ or ‘’horrible,’’ and said it fueled anxiety.

Such delays can be hard on clinicians and the healthcare system too. 

One 2022 study found that a typical academic radiation oncology practice spent about a half-million dollars per year seeking insurance preauthorization. Nationally, that number exceeds $40 million.

Then there is the burnout factor. 

Dr. Giap, an early-career physician who specializes in rare, aggressive sarcomas, works at an institution that helped pioneer proton therapy. She says it pains her to tell a desperate patient, like the 21-year-old, who has traveled to her from out of state that they have to wait. 

‘’Knowing that the majority of the cases are ultimately approved and that this wait is often unnecessary makes it even tougher,’’ she said.

Dr. Chino, a breast cancer specialist, has taken to warning patients before the alarming insurance letter arrives in the mail that their insurance may delay authorizing their care. But she tells patients that she will do everything she can to fight for them and develops a back-up plan to pivot to quickly, if needed.

‘’No one goes into medicine to spend their time talking to insurance companies,’’ said Dr. Chino.

The national trade group, America’s Health Insurance Plans (AHIP), did not return repeated requests for an interview for this story. But their official position, as stated on their website, is that “prior authorization is one of many tools health insurance providers use to promote safe, timely, evidence-based, affordable, and efficient care.”

Both Dr. Giap and Dr. Chino believe that prior authorization was developed with good intentions: to save healthcare costs and rein in treatments that don’t necessarily benefit patients. 

But, in their specialty, the burden has proliferated to a point that Dr. Chino characterizes as ‘’unconscionable.’’

She believes that policy changes like the proposed Improving Seniors’ Timely Access to Care Act — which would require real-time decisions for procedures that are routinely approved — could go a long way in improving patient care.

Meanwhile, Dr. Giap said, more research and professional guidelines are necessary to bolster insurance company confidence in newer technologies, particularly for rare cancers.

Her patient ultimately got her proton therapy and is ‘’doing relatively well, all things considered.’’

But not all the stories end like this.

Dr. Chino will never forget a patient with a cancer growing so rapidly she could see it protruding through her chest wall. She called for an urgent PET scan to see where else in the body the cancer might be brewing and rushed the planning process for radiation therapy, both of which faced prior authorization barriers. That scan — which ultimately showed the cancer had spread — was delayed for months.*

If the team had had those imaging results upfront, she said, they would have recommended a completely different course of treatment.

And her patient might be alive today.

‘’Unfortunately,” Dr. Chino said, “the people with the very worst prior authorization stories aren’t here anymore to tell you about them.”

*Correction,  10/4/24: An earlier version of this article erroneously stated that Dr. Chino called for surgery for her patient. She actually called for a PET scan and an urgent radiation start.

Fantine Giap, MD, sat across from a 21-year-old with a rare sarcoma at the base of her skull. 

Despite the large tumor, nestled in a sensitive area, the Boston-based radiation oncologist could envision a bright future for her patient. 

She and the other members of the patient’s care team had an impressive cancer-fighting arsenal at her fingertips. The team had recommended surgery, followed by proton therapy — a sophisticated tool able to deliver concentrated, razor-focused radiation to the once apple-sized growth, while sparing the fragile brain stem, optic nerve, and spinal cord. 

Surgery went as planned. But as the days and weeks wore on and insurance prior authorization for the proton therapy never came, the tumor roared back, leading to more surgeries and more complications. Ultimately, the young woman needed a tracheostomy and a feeding tube. 

By the time insurance said yes, more than 1 year from her initial visit, the future the team had envisioned seemed out of reach. 

“Unfortunately for this patient, it went from a potentially curable situation to a likely not curable situation,” recalled Dr. Giap, a clinician at Massachusetts General Hospital and instructor at Harvard Medical School, Boston. “I wanted to cry every day that she waited.’’ 

While a stark example, such insurance delays are not uncommon, according to new research published in JAMA Network Open.

The study of 206 denials in radiation oncology concluded that more than two-thirds were ultimately approved on appeal without changes, but often these approvals came only after costly delays that potentially compromised patient care.

Other studies have found that number to be even higher, with more than 86% of prior authorization requests ultimately approved with few changes.

‘’It gives you the idea that this entire process might be a little futile — that it’s just wasting people’s time,’’ said Fumiko Chino, MD, coauthor on the JAMA study and now an assistant professor in radiation oncology at MD Anderson Cancer Center in Houston. ‘’The problem is cancer doesn’t wait for bureaucracy.’’
 

Barriers at Every Step

As Dr. Chino and her study coauthors explained, advancements like intensity-modulated radiation therapy and stereotactic radiosurgery have allowed a new generation of specialists to treat previously untreatable cancers in ways that maximize tumor-killing power while minimizing collateral damage. But these tools require sophisticated planning, imaging, simulations and execution — all of which are subject to increased insurance scrutiny.

‘’We face barriers pretty much every step of the way for every patient,’’ said Dr. Chino.

To investigate how such barriers impact care, Dr. Chino and colleagues at Memorial Sloan Kettering Cancer Center — where she worked until July — looked at 206 cases in which payers denied prior authorization for radiation therapy from November 1, 2021 to December 8, 2022. 

The team found that 62% were ultimately approved without any change to technique or dose, while 28% were authorized, but with lower doses or less sophisticated techniques. Four people, however, never got authorization at all — three abandoned treatment altogether, and one sought treatment at another institution.

Treatment delays ranged from 1 day to 49 days. Eighty-three patients died.

Would some of them have lived if it weren’t for prior authorization?

Dr. Chino cannot say for sure, but did note that certain cancers, like cervical cancer, can grow so quickly that every day of delayed treatment makes them harder to control. 

Patients with metastatic or late-stage cancers are often denied more aggressive treatments by insurers who, in essence, “assume that they are going to die from their disease anyway,” Dr. Chino said. 

She views this as tragically shortsighted.

‘’There’s actually a strong body of evidence to show that if you treat even metastatic stage IV diseases aggressively, you can prolong not just quality of life but also quantity,’’ she said. 

In cases where the cancer is more localized and insurance mandates lower doses or cheaper techniques, the consequences can be equally heartbreaking.

‘’It’s like saying instead of taking an extra-strength Tylenol you can only have a baby aspirin,’’ she said. ‘’Their pain is less likely to be controlled, their disease is less likely to be controlled, and they are more likely to need retreatment.’’

Demand for new weight loss drugs has surged over the past few years. 

Led by the antiobesity drugs semaglutide (Wegovy) and tirzepatide (Zepbound), these popular medications — more commonly known as glucagon-like peptide 1 (GLP-1) agonists — have become game changers for shedding excess pounds.

Aside from obesity indications, both drugs have been approved to treat type 2 diabetes under different brand names and have a growing list of other potential benefits, such as reducing inflammation and depression. 

These antiobesity drugs could even have a place in cancer care.

While there’s limited data to support the use of GLP-1 agonists for weight loss in cancer, some oncologists have begun carefully integrating the antiobesity agents into care and studying their effects in this patient population.

The reason: Research suggests that obesity can reduce the effectiveness of cancer therapies, especially in patients with breast cancer, and can increase the risk for treatment-related side effects. 

The idea is that managing patients’ weight will improve their cancer outcomes, explained Lajos Pusztai, MD, PhD, a breast cancer specialist and professor of medicine at Yale School of Medicine in New Haven, Connecticut. 

Although Dr. Pusztai and his oncology peers at Yale don’t yet use GPL-1 agonists, Neil Iyengar, MD, and colleagues have begun doing so to help some patients with breast cancer manage their weight. Dr. Iyengar estimates that a few hundred — almost 40% — of his patients are on the antiobesity drugs.

“For a patient who has really tried to reduce their weight and who is in the obese range, that’s where I think the use of these medications can be considered,” said Dr. Iyengar, a breast cancer oncologist at Memorial Sloan Kettering Cancer Center in New York City. 

Why GLP-1s in Cancer?

GLP-1 is a hormone that the small intestine releases after eating. GLP-1 agonists work by mimicking GLP-1 to trigger the release of insulin and reduce the production of glucagon — two processes that help regulate blood sugar. 

These agents, such as Wegovy (or Ozempic when prescribed for diabetes), also slow gastric emptying and can make people feel fuller longer. 

Zebound (or Mounjaro for type 2 diabetes) is considered a dual GLP-1 and glucose-dependent insulinotropic polypeptide agonist, which may enhance its weight loss benefits.

In practice, however, these drugs can increase nausea and vomiting from chemotherapy, so Dr. Iyengar typically has patients use them afterwards, during maintenance treatment.

Oncologists don’t prescribe the drugs themselves but instead refer patients to endocrinologists or weight management centers that then write the prescriptions. Taking these drugs involves weekly subcutaneous injections patients can administer themselves.

Endocrinologist Emily Gallagher, MD, PhD, of Mount Sinai Hospital in New York City, estimates she has prescribed the antiobesity drugs to a few hundred patients with cancer and, like Dr. Iyengar, uses the drugs during maintenance treatment with hormone therapy for breast cancer. She also has used these agents in patients with prostate and endometrial cancers and has found the drugs can help counter steroid weight gain in multiple myeloma. 

But, to date, the evidence for using GPL-1 agonists in cancer remains limited and the practice has not yet become widespread.

Research largely comes down to a few small retrospective studies in patients with breast cancer receiving aromatase inhibitors. Although no safety issues have emerged so far, these initial reports suggest that the drugs lead to significantly less weight loss in patients with cancer compared to the general population. 

Dr. Iyengar led one recent study, presented at the 2024 annual meeting of the American Society of Clinical Oncology, in which he and his team assessed outcomes in 75 women with breast cancer who received a GLP-1 agonist. Almost 80% of patients had diabetes, and 60% received hormone therapy, most commonly an aromatase inhibitor. Patients’ median body mass index (BMI) at baseline was 34 kg/m² (range, 23-50 kg/m²).

From baseline, patients lost 6.2 kg, on average, or about 5% of their total body weight, 12 months after initiating GLP-1 therapy. 

In contrast, phase 3 trials show much higher mean weight loss — about two times — in patients without cancer. 

Another recent study also reported modest weight loss results in patients with breast cancer undergoing endocrine therapy. The researchers reported that, at 12 months, Wegovy led to 4.34% reduction in BMI, compared with a 14% change reported in the general population. Zebound, however, was associated with a 2.31% BMI increase overall — though some patients did experience a decrease — compared with a 15% reduction in the general population. 

“These findings indicate a substantially reduced weight loss efficacy in breast cancer patients on endocrine therapy compared to the general population,” the authors concluded.

It’s unclear why the drugs appear to not work as well in patients with cancer. It’s possible that hormone therapy or metabolic changes interfere with their effectiveness, given that some cancer therapies lead to weight gain. Steroids and hormone therapies, for instance, often increase appetite, and some treatments can slow patients’ metabolism or lead to fatigue, which can make it harder to exercise.

Patients with cancer may need a higher dose of GLP-1 agonists to achieve similar weight loss to the general population, Dr. Iyengar noted.

However, Dr. Gallagher said, in her own experience, she hasn’t found the drugs to be less effective in patients with cancer, especially the newer agents, like Wegovy and Zepbound. 

As for safety, Wegovy and Zepbound both carry a black box warning for thyroid C-cell tumors, including medullary thyroid carcinoma. (Recent research, however, has found that GLP-1 agonists do not increase thyroid cancer risk). 

These antiobesity agents are also contraindicated in patients with a personal or family history of medullary thyroid carcinoma and in patients who have multiple endocrine neoplasia syndrome type 2, which is associated with medullary thyroid carcinoma.

Dr. Gallagher hasn’t seen any secondary tumors — thyroid or otherwise — in her patients with cancer, but she follows the labeling contraindications. Dr. Iyengar also noted that more recent and larger data sets have shown no impact on this risk, which may not actually exist, he said

Dr. Gallagher remains cautious about using GPL-1 agonists in patients who have had bariatric surgery because these agents can compound the slower gastric emptying and intestinal transit from surgery, potentially leading to gastrointestinal obstructions. 

Looking ahead, GPL-1 manufacturers are interested in adding cancer indications to the drug labeling. Both Dr. Iyengar and Dr. Gallagher said their institutions are in talks with companies to participate in large, multicenter, global phase 3 trials.

Dr. Iyengar welcomes the efforts, not only to test the effectiveness of GPL-1 agonists in oncology but also to “nail down” their safety in cancer. 

“I don’t think that there’s mechanistically anything that’s particularly worrisome,” and current observations suggest that these drugs are likely to be safe, Dr. Iyengar said. Even so, “GLP-1 agonists do a lot of things that we don’t fully understand yet.”

The bigger challenge, Dr. Iyengar noted, is that companies will have to show a sizable benefit to using these drugs in patients with cancer to get the Food and Drug Administration’s approval. And to move the needle on cancer-specific outcomes, these antiobesity drugs will need to demonstrate significant, durable weight loss in patients with cancer. 

But if these drugs can do that, “I think it’s going to be one of the biggest advances in medicine and oncology given the obesity and cancer epidemic,” Dr. Iyengar said. 

Dr. Iyengar has adviser and/or researcher ties with companies that make or are developing GPL-1 agonists, including AstraZeneca, Novartis, Gilead, and Pfizer. Dr. Gallagher is a consultant for Novartis, Flare Therapeutics, Reactive Biosciences, and Seagen.

TOPLINE:

Patients with stage I non–small cell lung cancer (NSCLC) treated with stereotactic body radiotherapy (SBRT) have a low rate of acute toxicities and 90-day mortality, according to a recent study evaluating real-world patient outcomes.

METHODOLOGY:

• SBRT is generally considered a safe treatment option in patients with stage I NSCLC who have medically inoperable tumors or who refuse surgery. Although rare, clinically relevant acute toxicities or early mortality can occur.
• In the current real-world analysis, researchers explored toxicity and 90-day mortality outcomes in patients who received SBRT to develop a better understanding of how often they happen and whether certain patients are at higher risk.
• Researchers analyzed data from the Dutch Lung Cancer Audit for Radiotherapy database, which included 7279 patients with stage I NSCLC who received SBRT between January 2017 and December 2021.
• Participants had a mean age of 72.5 years; 21.6% were older than 80 years. Over half were men (50.7%), most (73.3%) had WHO scores of 0-1, and about two thirds (64.6%) had cT1a-b tumors, mostly in the upper lobes (65.2%).
• Prediction models for acute toxicity and 90-day mortality were developed and internally validated using logistic regression analysis. Acute toxicity was defined as grade 2 or higher radiation pneumonitis or grade 3 or higher non-hematologic toxicity within 90 days after SBRT. The 90-day mortality was defined as mortality from any cause within 90 days after SBRT.

TAKEAWAY:

• Acute toxicity was observed in 3.8% patients, with more common types including dyspnea (1.8%), radiation pneumonitis (1.2%), fatigue (0.3%), and dysphagia (0.2%).
• Predictors for acute toxicity included WHO performance status of 2 or higher (adjusted odds ratio [aOR], 1.89; P = .003), middle or lower lobe tumor location (aOR, 1.38), cT1c-cT2a stage (aOR, 1.66), as well as lower forced expiratory volume in 1 second and higher mean lung dose.
• Overall, 90-day mortality was observed in 1.7% patients, with predictors including male sex, WHO performance status of 2 or higher (aOR, 6.11; P < .001), and acute toxicity (aOR, 8.89; P < .001).
• Advanced age was not associated with a higher risk for acute toxicity or 90-day mortality.

IN PRACTICE:

“This real-world study confirms that clinically relevant acute toxicity after lung SBRT for stage I NSCLC is rare,” and the 90-day mortality rate is low, the authors wrote. “Although these findings could inform clinical practice and enable individualized risk estimations, these parameters (and the others in the presented nomograms) should not serve as contraindication for SBRT as the benefits in terms of local control and survival outweigh the risks in most patients.”

This study, led by Peter S.N. van Rossum, MD, PhD, Amsterdam UMC in Amsterdam, the Netherlands, was published online in Journal of Thoracic Oncology.

LIMITATIONS:

Patients with ultracentral tumor locations were excluded, which may have limited the generalizability of the findings. The Dutch Lung Cancer Audit for Radiotherapy database does not register whether a patient has interstitial lung disease or whether the treated tumor is at a central location, which carry increased risks for toxicity. The findings may not be applicable to patients receiving combined immunotherapy and SBRT, as this combination was not included in the current analysis. External validation of the prediction models is needed for application outside the Netherlands.

DISCLOSURES:

The authors declared no conflicts of interest.

The US Food and Drug Administration (FDA) has approved osimertinib (Tagrisso, AstraZeneca) for the treatment of locally advanced, unresectable non–small cell lung cancer (NSCLC) in certain adult patients.

Specifically, the third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) was approved for patients whose disease has not progressed during or after concurrent or sequential platinum-based chemoradiation therapy and whose tumors have EGFR exon 19 deletions or exon 21 L858R mutations. Such EGFR mutations can be detected by an FDA-approved test.

The FDA approved osimertinib in combination with platinum-based chemotherapy as first-line treatment for patients with locally advanced or metastatic NSCLC with the same mutations in February. The EGFR-TKI also carries other indications, including as first-line monotherapy for locally advanced or metastatic EGFR-mutated NSCLC.
 

Trial Findings Supporting Latest Approval

AstraZeneca announced in June that osimertinib had been granted Priority Review and Breakthrough Therapy Designation for its newest indication.

The September 25 approval was based on findings from the randomized, placebo-controlled LAURA trial of 216 patients, which demonstrated improved median progression-free survival with osimertinib vs placebo (39.1 vs 5.6 months; hazard ratio, 0.16). Overall survival results were immature at the most recent analysis, but “no trend towards a detriment was observed,” with 36% of prespecified deaths for the final analysis reported, according to an FDA press release.
 

Adverse Events

Study participants were randomized 2:1 to receive the osimertinib recommended dose of 80 mg given orally once daily or placebo until disease progression or unacceptable toxicity. The most common adverse reactions, occurring in at least 20% of patients, were lymphopenia, leukopenia, interstitial lung disease/pneumonitis, thrombocytopenia, neutropenia, rash, diarrhea, nail toxicity, musculoskeletal pain, cough, and COVID-19 infection.

TOPLINE:

Medicare Advantage plans had lower adjusted total resource use than traditional Medicare for patients with cancer undergoing chemotherapy, with no difference in 18-month survival between the two groups.

METHODOLOGY:

• Private Medicare Advantage plans enroll more than half of the Medicare population, but it is unknown if or how the cost restrictions they impose affect chemotherapy, which accounts for a large portion of cancer care costs.
• Researchers conducted a cohort study using national Medicare data from January 2015 to December 2019 to look at Medicare Advantage enrollment and treatment patterns for patients with cancer receiving chemotherapy.
• The study included 96,501 Medicare Advantage enrollees and 206,274 traditional Medicare beneficiaries who initiated chemotherapy between January 2016 and December 2019 (mean age, ~73 years; ~56% women; Hispanic individuals, 15% and 8%; Black individuals, 15% and 8%; and White individuals, 75% and 86%, respectively).
• Resource use and care quality were measured during a 6-month period following chemotherapy initiation, and survival days were measured 18 months after beginning chemotherapy.
• Resource use measures included hospital inpatient services, outpatient care, prescription drugs, hospice services, and chemotherapy services. Quality measures included chemotherapy-related emergency visits and hospital admissions, as well as avoidable emergency visits and preventable hospitalizations.

TAKEAWAY:

• Medicare Advantage plans had lower resource use than traditional Medicare per enrollee with cancer undergoing chemotherapy ($8718 lower; 95% CI, $8343-$9094).
• The lower resource use was largely caused by fewer chemotherapy visits and less expensive chemotherapy per visit in Medicare Advantage plans ($5032 lower; 95% CI, $4772-$5293).
• Medicare Advantage enrollees had 2.5 percentage points fewer chemotherapy-related emergency department visits and 0.7 percentage points fewer chemotherapy-related hospitalizations than traditional Medicare beneficiaries.
• There was no clinically meaningful difference in survival between Medicare Advantage and traditional Medicare beneficiaries during the 18 months following chemotherapy initiation.

IN PRACTICE:

“Our new finding is that MA [Medicare Advantage] plans had lower resource use than TM [traditional Medicare] among enrollees with cancer undergoing chemotherapy — a serious condition managed by specialists and requiring expensive treatments. This suggests that MA’s cost advantages over TM are not limited to conditions for which low-cost primary care management can avoid costly services,” the authors wrote.

SOURCE:

The study was led by Yamini Kalidindi, PhD, McDermott+ Consulting, Washington, DC. It was published online on September 20, 2024, in JAMA Network Open (doi: 10.1001/jamanetworkopen.2024.34707), with a commentary.

LIMITATIONS:

The study’s findings may be affected by unobserved patient characteristics despite the use of inverse-probability weighting. The exclusion of Medicare Advantage enrollees in contracts with incomplete encounter data limits the generalizability of the results. The study does not apply to beneficiaries without Part D drug coverage. Quality measures were limited to those available from claims and encounter data, lacking information on patients’ cancer stage. The 18-month measure of survival might not adequately capture survival differences associated with early-stage cancers. The study did not measure whether patient care followed recommended guidelines.

Various authors reported grants from the National Institute on Aging, the National Institutes of Health, The Commonwealth Fund, Arnold Ventures, the National Cancer Institute, the Department of Defense, and the National Institute of Health Care Management.

Despite the “remarkable progress” in cancer research and care, cancer remains “an ongoing public health challenge,” which requires significant attention and funding, according to the Cancer Progress Report 2024 from the American Association for Cancer Research (AACR).

The AACR’s 216-page report — an annual endeavor now in its 14th year — focused on the “tremendous” strides made in cancer care, prevention, and early detection and highlighted areas where more research and attention are warranted. 

One key area is funding. For the first time since 2016, federal funding for the National Institutes of Health (NIH) and National Cancer Institute (NCI) decreased in the past year. The cuts followed nearly a decade of funding increases that saw the NIH budget expand by nearly $15 billion, and that allowed for a “rapid pace and broad scope” of advances in cancer, AACR’s chief executive officer Margaret Foti, MD, PhD, said during a press briefing.

These recent cuts “threaten to curtail the medical progress seen in recent years and stymie future advancements,” said Dr. Foti, who called on Congress to commit to funding cancer research at significant and consistent levels to “maintain the momentum of progress against cancer.”
 

Inside the Report: Big Progress

Overall, advances in prevention, early detection, and treatment have helped catch more cancers earlier and save lives. 

According to the AACR report, the age-adjusted overall cancer death rate in the United States fell by 33% between 1991 and 2021, meaning about 4.1 million cancer deaths were averted. The overall cancer death rate for children and adolescents has declined by 24% in the past 2 decades. The 5-year relative survival rate for children diagnosed with cancer in the US has improved from 58% for those diagnosed in the mid-1970s to 85% for those diagnosed between 2013 and 2019.

The past fiscal year has seen many new approvals for cancer drugs, diagnostics, and screening tests. From July 1, 2023, to June 30, 2024, the Food and Drug Administration (FDA) approved 15 new anticancer therapeutics, as well as 15 new indications for previously approved agents, one new imaging agent, several artificial intelligence (AI) tools to improve early cancer detection and diagnosis, and two minimally invasive tests for assessing inherited cancer risk or early cancer detection, according to the report.

“Cancer diagnostics are becoming more sophisticated,” AACR president Patricia M. LoRusso, DO, PhD, said during the briefing. “New technologies, such as spatial transcriptomics, are helping us study tumors at a cellular level, and helping to unveil things that we did not initially even begin to understand or think of. AI-based approaches are beginning to transform cancer detection, diagnosis, clinical decision-making, and treatment response monitoring.” 

The report also highlights the significant progress in many childhood and adolescent/young adult cancers, Dr. LoRusso noted. These include FDA approvals for two new molecularly targeted therapeutics: tovorafenib for children with certain types of brain tumor and repotrectinib for children with a wide array of cancer types that have a specific genetic alteration known as NTRK gene fusion. It also includes an expanded approval for eflornithine to reduce the risk for relapse in children with high-risk neuroblastoma.

“Decades — decades — of basic research discoveries, have led to these clinical breakthroughs,” she stressed. “These gains against cancer are because of the rapid progress in our ability to decode the cancer genome, which has opened new and innovative avenues for drug development.”
 

The Gaps

Even with progress in cancer prevention, early detection, and treatment, cancer remains a significant issue.

“In 2024, it is estimated that more than 2 million new cases of cancer will be diagnosed in the United States. More than 611,000 people will die from the disease,” according to the report.

The 2024 report shows that incidence rates for some cancers are increasing in the United States, including vaccine-preventable cancers such as human papillomavirus (HPV)–associated oral cancers and, in young adults, cervical cancers. A recent analysis also found that overall cervical cancer incidence among women aged 30-34 years increased by 2.5% a year between 2012 and 2019.

Furthermore, despite clear evidence demonstrating that the HPV vaccine reduces cervical cancer incidence, uptake has remained poor, with only 38.6% of US children and adolescents aged 9-17 years receiving at least one dose of the vaccine in 2022.

Early-onset cancers are also increasing. Rates of breast, colorectal, and other cancers are on the rise in adults younger than 50 years, the report noted.

The report also pointed to data that 40% of all cancer cases in the United States can be attributed to preventable factors, such as smoking, excess body weight, and alcohol. However, our understanding of these risk factors has improved. Excessive levels of alcohol consumption have, for instance, been shown to increase the risk for six different types of cancer: certain types of head and neck cancer, esophageal squamous cell carcinoma, and breast, colorectal, liver, and stomach cancers.

Financial toxicity remains prevalent as well.

The report explains that financial hardship following a cancer diagnosis is widespread, and the effects can last for years. In fact, more than 40% of patients can spend their entire life savings within the first 2 years of cancer treatment. Among adult survivors of childhood cancers, 20.7% had trouble paying their medical bills, 29.9% said they had been sent to debt collection for unpaid bills, 14.1% had forgone medical care, and 26.8% could not afford nutritious meals.

For young cancer survivors, the lifetime costs associated with a diagnosis of cancer are substantial, reaching an average of $259,324 per person.

On a global level, it is estimated that from 2020 to 2050, the cumulative economic burden of cancer will be $25.2 trillion.
 

The Path Forward

Despite these challenges, Dr. LoRusso said, “it is unquestionable that we are in a time of unparalleled opportunities in cancer research.

“I am excited about what the future holds for cancer research, and especially for patient care,” she said. 

However, funding commitments are needed to avoid impeding this momentum and losing a “talented and creative young workforce” that has brought new ideas and new technologies to the table.

Continued robust funding will help “to markedly improve cancer care, increase cancer survivorship, spur economic growth, and maintain the United States’ position as the global leader in science and medical research,” she added.

The AACR report specifically calls on Congress to:

• Appropriate at least $51.3 billion in fiscal year 2025 for the base budget of the NIH and at least $7.934 billion for the NCI.
• Provide $3.6 billion in dedicated funding for Cancer Moonshot activities through fiscal year 2026 in addition to other funding, consistent with the President’s fiscal year 2025 budget.
• Appropriate at least $472.4 million in fiscal year 2025 for the CDC’s Division of Cancer Prevention to support comprehensive cancer control, central cancer registries, and screening and awareness programs for specific cancers.
• Allocate $55 million in funding for the Oncology Center of Excellence at FDA in fiscal year 2025 to provide regulators with the staff and tools necessary to conduct expedited review of cancer-related medical products.

By working together with Congress and other stakeholders, “we will be able to accelerate the pace of progress and make major strides toward the lifesaving goal of preventing and curing all cancers at the earliest possible time,” Dr. Foti said. “I believe if we do that ... one day we will win this war on cancer.”

Despite the “remarkable progress” in cancer research and care, cancer remains “an ongoing public health challenge,” which requires significant attention and funding, according to the Cancer Progress Report 2024 from the American Association for Cancer Research (AACR).

The AACR’s 216-page report — an annual endeavor now in its 14th year — focused on the “tremendous” strides made in cancer care, prevention, and early detection and highlighted areas where more research and attention are warranted. 

One key area is funding. For the first time since 2016, federal funding for the National Institutes of Health (NIH) and National Cancer Institute (NCI) decreased in the past year. The cuts followed nearly a decade of funding increases that saw the NIH budget expand by nearly $15 billion, and that allowed for a “rapid pace and broad scope” of advances in cancer, AACR’s chief executive officer Margaret Foti, MD, PhD, said during a press briefing.

These recent cuts “threaten to curtail the medical progress seen in recent years and stymie future advancements,” said Dr. Foti, who called on Congress to commit to funding cancer research at significant and consistent levels to “maintain the momentum of progress against cancer.”
 

Inside the Report: Big Progress

Overall, advances in prevention, early detection, and treatment have helped catch more cancers earlier and save lives. 

According to the AACR report, the age-adjusted overall cancer death rate in the United States fell by 33% between 1991 and 2021, meaning about 4.1 million cancer deaths were averted. The overall cancer death rate for children and adolescents has declined by 24% in the past 2 decades. The 5-year relative survival rate for children diagnosed with cancer in the US has improved from 58% for those diagnosed in the mid-1970s to 85% for those diagnosed between 2013 and 2019.

The past fiscal year has seen many new approvals for cancer drugs, diagnostics, and screening tests. From July 1, 2023, to June 30, 2024, the Food and Drug Administration (FDA) approved 15 new anticancer therapeutics, as well as 15 new indications for previously approved agents, one new imaging agent, several artificial intelligence (AI) tools to improve early cancer detection and diagnosis, and two minimally invasive tests for assessing inherited cancer risk or early cancer detection, according to the report.

“Cancer diagnostics are becoming more sophisticated,” AACR president Patricia M. LoRusso, DO, PhD, said during the briefing. “New technologies, such as spatial transcriptomics, are helping us study tumors at a cellular level, and helping to unveil things that we did not initially even begin to understand or think of. AI-based approaches are beginning to transform cancer detection, diagnosis, clinical decision-making, and treatment response monitoring.” 

The report also highlights the significant progress in many childhood and adolescent/young adult cancers, Dr. LoRusso noted. These include FDA approvals for two new molecularly targeted therapeutics: tovorafenib for children with certain types of brain tumor and repotrectinib for children with a wide array of cancer types that have a specific genetic alteration known as NTRK gene fusion. It also includes an expanded approval for eflornithine to reduce the risk for relapse in children with high-risk neuroblastoma.

“Decades — decades — of basic research discoveries, have led to these clinical breakthroughs,” she stressed. “These gains against cancer are because of the rapid progress in our ability to decode the cancer genome, which has opened new and innovative avenues for drug development.”
 

The Gaps

Even with progress in cancer prevention, early detection, and treatment, cancer remains a significant issue.

“In 2024, it is estimated that more than 2 million new cases of cancer will be diagnosed in the United States. More than 611,000 people will die from the disease,” according to the report.

The 2024 report shows that incidence rates for some cancers are increasing in the United States, including vaccine-preventable cancers such as human papillomavirus (HPV)–associated oral cancers and, in young adults, cervical cancers. A recent analysis also found that overall cervical cancer incidence among women aged 30-34 years increased by 2.5% a year between 2012 and 2019.

Furthermore, despite clear evidence demonstrating that the HPV vaccine reduces cervical cancer incidence, uptake has remained poor, with only 38.6% of US children and adolescents aged 9-17 years receiving at least one dose of the vaccine in 2022.

Early-onset cancers are also increasing. Rates of breast, colorectal, and other cancers are on the rise in adults younger than 50 years, the report noted.

The report also pointed to data that 40% of all cancer cases in the United States can be attributed to preventable factors, such as smoking, excess body weight, and alcohol. However, our understanding of these risk factors has improved. Excessive levels of alcohol consumption have, for instance, been shown to increase the risk for six different types of cancer: certain types of head and neck cancer, esophageal squamous cell carcinoma, and breast, colorectal, liver, and stomach cancers.

Financial toxicity remains prevalent as well.

The report explains that financial hardship following a cancer diagnosis is widespread, and the effects can last for years. In fact, more than 40% of patients can spend their entire life savings within the first 2 years of cancer treatment. Among adult survivors of childhood cancers, 20.7% had trouble paying their medical bills, 29.9% said they had been sent to debt collection for unpaid bills, 14.1% had forgone medical care, and 26.8% could not afford nutritious meals.

For young cancer survivors, the lifetime costs associated with a diagnosis of cancer are substantial, reaching an average of $259,324 per person.

On a global level, it is estimated that from 2020 to 2050, the cumulative economic burden of cancer will be $25.2 trillion.
 

The Path Forward

Despite these challenges, Dr. LoRusso said, “it is unquestionable that we are in a time of unparalleled opportunities in cancer research.

“I am excited about what the future holds for cancer research, and especially for patient care,” she said. 

However, funding commitments are needed to avoid impeding this momentum and losing a “talented and creative young workforce” that has brought new ideas and new technologies to the table.

The US Food and Drug Administration (FDA) has granted a second-line indication to amivantamab-vmjw (Rybrevant, Janssen Biotech) in non–small-cell lung cancer (NSCLC). 

Amivantamab with carboplatin and pemetrexed is now indicated for adults with locally advanced or metastatic NSCLC with EGFR exon 19 deletions or exon 21 L858R substitution mutations whose disease has progressed on or after treatment with an EGFR tyrosine kinase inhibitor (TKI).

The FDA has already approved first-line use of amivantamab in combination with carboplatin and pemetrexed in patients with locally advanced or metastatic NSCLC with EGFR exon 20 insertion mutations, as reported by Medscape Medical News. 

The second-line approval for amivantamab plus chemotherapy “may address the most common mechanisms of treatment resistance to third-generation EGFR TKIs, such as osimertinib, in the first line,” Martin Dietrich, MD, PhD, oncologist, Cancer Care Centers of Brevard in Florida, said in a company news release.

“This multitargeted combination extended progression-free survival (PFS) and improved overall response compared to chemotherapy alone, offering an important and effective new second-line option for patients,” Dr. Dietrich added. 

The second-line indication is supported by the phase 3 MARIPOSA-2 study, which included 657 patients with locally advanced or metastatic NSCLC with EGFR exon 19 deletions or exon 21 L858R substitution mutations and disease progression on or after receiving osimertinib.

The study demonstrated a 52% reduced risk of disease progression or death when amivantamab was added to carboplatin and pemetrexed (hazard ratio, 0.48). 

Median PFS was 6.3 months with amivantamab vs 4.2 months with chemotherapy alone. The confirmed objective response rate was 53% in the amivantamab plus chemotherapy group vs 29% in the chemotherapy only group. 

The most common adverse reactions, occurring in at least 20% of patients, were rash, infusion-related reactions, fatigue, nail toxicity, nausea, constipation, edema, stomatitis, decreased appetite, musculoskeletal pain, vomiting, and COVID-19 infection.

The company noted that amivantamab in combination with chemotherapy is the only category 1 treatment option in National Comprehensive Cancer Network clinical practice guidelines for patients with EGFR-mutated NSCLC who have progressed on osimertinib and who are symptomatic with multiple lesions.

Pesticides have transformed modern agriculture by boosting production yields and helping alleviate food insecurity amid rapid global population growth. However, from a public health perspective, exposure to pesticides has been linked to numerous harmful effects, including neurologic disorders like Parkinson’s disease, weakened immune function, and an increased risk for cancer.

Pesticide exposure has been associated with cancers such as colorectal cancer, lung cancer, leukemia (in children and adults), lymphoma, and pancreatic cancer. But these studies primarily have focused on specific groups of individuals with known exposure to certain pesticides or cancer types, thus offering a limited perspective.

A comprehensive assessment of how pesticide use affects cancer risk across a broader population has yet to be conducted.

A recent population-level study aimed to address this gap by evaluating cancer risks in the US population using a model that accounts for pesticide use and adjusts for various factors. The goal was to identify regional disparities in exposure and contribute to the development of public health policies that protect populations from potential harm.
 

Calculating Cancer Risk

Researchers developed a model using several data sources to estimate the additional cancer risk from agricultural pesticide use. Key data included:

• Pesticide use data from the US Geological Survey in 2019, which covered 69 agricultural pesticides across 3143 counties
• Cancer incidence rates per 100,000 people, which were collected between 2015 and 2019 by the National Institutes of Health and the Centers for Disease Control and Prevention; these data covered various cancers, including bladder, colorectal, leukemia, lung, non-Hodgkin lymphoma, and pancreatic cancers
• Covariates, including smoking prevalence, the Social Vulnerability Index, agricultural land use, and total US population in 2019

Pesticide use profile patterns were developed using latent class analysis, a statistical method used to identify homogeneous subgroups within a heterogeneous population. A generalized linear model then estimated how these pesticide use patterns and the covariates affected cancer incidence.

The model highlighted regions with the highest and lowest “additional” cancer risks linked to pesticide exposure, calculating the estimated increase in cancer cases per year that resulted from variations in agricultural pesticide use.
 

Midwest Most Affected

While this model doesn’t establish causality or assess individual risk, it reveals regional trends in the association between pesticide use patterns and cancer incidence from a population-based perspective.

The Midwest, known for its high corn production, emerged as the region most affected by pesticide use. Compared with regions with the lowest risk, the Midwest faced an additional 154,541 cancer cases annually across all types. For colorectal and pancreatic cancers, the yearly increases were 20,927 and 3835 cases, respectively. Similar trends were observed for leukemia and non-Hodgkin lymphoma.
 

Pesticides vs Smoking

The researchers also estimated the additional cancer risk related to smoking, using the same model. They found that pesticides contributed to a higher risk for cancer than smoking in several cases.

The most significant difference was observed with non-Hodgkin lymphoma, where pesticides were linked to 154.1% more cases than smoking. For all cancers combined, as well as bladder cancer and leukemia, the increases were moderate: 18.7%, 19.3%, and 21.0%, respectively.

This result highlights the importance of considering pesticide exposure alongside smoking when studying cancer risks.
 

Expanding Scope of Research

Some limitations of this study should be noted. Certain counties lacked complete data, and there was heterogeneity in the size and population of the counties studied. The research also did not account for seasonal and migrant workers, who are likely to be heavily exposed. In addition, the data used in the study were not independently validated, and they could not be used to assess individual risk.

The effect of pesticides on human health is a vast and critical field of research, often focusing on a limited range of pesticides or specific cancers. This study stands out by taking a broader, more holistic approach, aiming to highlight regional inequalities and identify less-studied pesticides that could be future research priorities.

Given the significant public health impact, the authors encouraged the authorities to share these findings with the most vulnerable communities to raise awareness.

Compared with regions with the lowest risk, the Midwest faced an additional 154,541 cancer cases annually across all types. For colorectal and pancreatic cancers, the yearly increases were 20,927 and 3835 cases, respectively. Similar trends were observed for leukemia and non-Hodgkin lymphoma.
 

Pesticides vs Smoking

The researchers also estimated the additional cancer risk related to smoking, using the same model. They found that pesticides contributed to a higher risk for cancer than smoking in several cases.

The most significant difference was observed with non-Hodgkin lymphoma, where pesticides were linked to 154.1% more cases than smoking. For all cancers combined, as well as bladder cancer and leukemia, the increases were moderate: 18.7%, 19.3%, and 21.0%, respectively.

This result highlights the importance of considering pesticide exposure alongside smoking when studying cancer risks.
 

Expanding Scope of Research

Some limitations of this study should be noted. Certain counties lacked complete data, and there was heterogeneity in the size and population of the counties studied. The research also did not account for seasonal and migrant workers, who are likely to be heavily exposed. In addition, the data used in the study were not independently validated, and they could not be used to assess individual risk.

The effect of pesticides on human health is a vast and critical field of research, often focusing on a limited range of pesticides or specific cancers. This study stands out by taking a broader, more holistic approach, aiming to highlight regional inequalities and identify less-studied pesticides that could be future research priorities.

Given the significant public health impact, the authors encouraged the authorities to share these findings with the most vulnerable communities to raise awareness.

The Food and Drug Administration (FDA) has approved atezolizumab and hyaluronidase-tqjs (Tecentriq Hybreza, Genentech) as a subcutaneous injection in adults, covering all approved indications of the intravenous (IV) formulation.

Approved indications include non–small cell lung cancer (NSCLC), SCLC, hepatocellular carcinoma, melanoma, and alveolar soft part sarcoma. Specific indications are available with the full prescribing information at Drugs@FDA.

This is the first programmed death–ligand 1 inhibitor to gain approval for subcutaneous administration.

“This approval represents a significant option to improve the patient experience,” Ann Fish-Steagall, RN, Senior Vice President of Patient Services at the LUNGevity Foundation stated in a Genentech press release.

Subcutaneous atezolizumab and hyaluronidase-tqjs was evaluated in the open-label, randomized IMscin001 trial of 371 adult patients with locally advanced or metastatic NSCLC who were not previously exposed to cancer immunotherapy and who had disease progression following treatment with platinum-based chemotherapy. Patients were randomized 2:1 to receive subcutaneous or IV administration until disease progression or unacceptable toxicity.

Atezolizumab exposure, the primary outcome measure of the study, met the lower limit of geometric mean ratio above the prespecified threshold of 0.8 (cycle 1C trough, 1.05; area under the curve for days 0-21, 0.87).

No notable differences were observed in overall response rate, progression-free survival, or overall survival between the two formulations, according to the FDA approval notice.

The confirmed overall response rate was 9% in the subcutaneous arm and 8% intravenous arm.

Adverse events of any grade occurring in at least 10% of patients were fatigue, musculoskeletal pain, cough, dyspnea, and decreased appetite.

The recommended dose for subcutaneous injection is one 15 mL injection, which contains 1875 mg of atezolizumab and 30,000 units of hyaluronidase.

Injections should be administered in the thigh over approximately 7 minutes every 3 weeks. By contrast, IV administration generally takes 30-60 minutes.
