For more than three decades, the federal government sought to make amends to countless Americans who developed cancer after being exposed to radiation from nuclear testing in the Southwest or while working in the uranium mining industry.

As of 2022, more than 40,000 patients with cancer successfully applied for $2.6 billion in compensation. Recipients included “downwinders” who were eligible for $50,000 each if they lived in certain areas of Nevada, Utah, and Arizona during specified nuclear testing periods and developed a covered form of cancer.

In June 2024, however, the Radiation Exposure Compensation Program expired amid infighting among Republicans in Congress over whether to expand it. For now, no one can make a claim, even though many downwinders are still alive and continue to be diagnosed with covered cancers decades after they were exposed in the 1940s, 1950s, and 1960s.

There’s a glimmer of good news. The federal government continues to support free medical screenings for eligible people, including certain downwinders and uranium workers. Meanwhile, there are still important roles for clinicians across the country to play as politicians figure out what — if anything — to do next regarding those exposed to radiation.

“We are still here. We can still screen people,” Zachary Davis, program director for the Radiation Exposure Screening and Education Program, The University of New Mexico, in Albuquerque, New Mexico, said in an interview.
 

Still-Unfolding Legacy of Radiation Exposure

No one knew just how far radiation would spread when the first nuclear bomb was tested in New Mexico in July 1945. Would it cover the state? The entire Southwest? The whole nation?

It also wasn’t clear how radiation would affect people’s health. “There was an awareness that some cancers were caused by radiation, but there wasn’t a cohesive understanding of what the problem was,” Joseph Shonka, PhD, a health physicist who studies radiation exposure and has worked for decades in nuclear engineering, said in an interview.

Now, nearly eight decades later, scientists are still figuring out the full extent of radioactive fallout from nuclear testing. Just last year, a study suggested that radiation from 94 nuclear weapon tests in the Southwest from 1945 to 1962 reached 46 states along with Canada and Mexico.

Activists believe the tests triggered untold number of cancer cases in residents who were exposed in downwind areas:

“My brother died of stomach cancer; my mom died of bone cancer. One of my sisters is surviving brain tumors, and the other one is surviving thyroid cancer,” one New Mexico man recently told ABC-TV’s “Nightline.”

In Idaho, a downwinder advocate told Idaho Capital Sun that everyone who attended a reception for her newly married parents in 1952 — just weeks after a nuclear test — developed cancer or “weird medical complications.” That included her parents, who both had cancer. Her two older brothers, born in 1953 and 1955, also developed cancer, and she’s tracked many other cases in the small town of Emmett.

In Utah, another downwinder advocate told Utah News Dispatch that cancer was common in Salt Lake City neighborhood, where she grew up, which was exposed to fallout. She developed thyroid cancer, her younger sister developed stomach cancer, and an older sister died of lupus, which is connected to radiation exposure. But Salt Lake City isn’t in one of the regions of Utah covered by the federal compensation program, so the advocate can’t get a $50,000 payment.

Downwinders who lived in New Mexico, Idaho, and the Salt Lake City area of Utah are not covered by the federal compensation program. That means none of these people or their descendants are eligible for payments — yet.
 

Decades After Nuclear Testing, the Government Responds

In 1990, Congress passed the Radiation Exposure Compensation Act, which allowed compensation to people with cancer at several levels. It was later expanded. Downwinders — including those who’ve moved elsewhere over the years — were eligible for $50,000. Onsite participants in nuclear testing could get $75,000. Uranium miners, millers, and ore transporters in 11 states west of the Mississippi River could get $100,000.

Among downwinders, eligible cancers included blood cancers (leukemias with the exception of chronic lymphocytic leukemia, multiple myeloma, and non-Hodgkin’s lymphomas) and a long list of solid organ cancers such as thyroid, breast, stomach, brain, lung, colon, and liver cancers.

“When it comes to blood-related cancers, we do see leukemias, lymphomas, and multiple myeloma, but these cancers were more likely to occur sooner after fallout exposure,” said Laura Shaw, MD, principal investigator who oversees the radiation exposure screening program at the University of Nevada, Las Vegas. “At this point, we see more pancreatic, thyroid, lung, stomach, bladder, and breast cancer.”

The compensation program had major limitations, critics said. “It left out a lot of communities that were exposed,” said Lilly Adams, senior outreach coordinator with the Union of Concerned Scientists (UCS), which supports expanding the program. A national nonprofit organization, UCS was founded more than 50 years ago by scientists and students at the Massachusetts Institute of Technology.

“You have this pretty small amount of one-time compensation, and that’s it,” Adams said in an interview. “You can’t get reimbursed for medical costs or lost wages.” Still, “as flawed as the program is, it’s really valuable for the people who are eligible,” she noted.
 

Now Congress Is Divided on Next Steps

Some lawmakers have recognized the need to do more for those who developed cancer that’s potentially linked to radiation exposure. As the June 2024 expiration of the Radiation Exposure Compensation Act loomed, Democrats and Republicans in Congress worked together to extend and expand the program.

They introduced a bill for higher compensation — $100,000 per person — and the widening of covered downwinder areas to all of Arizona, Nevada, and Utah (which had only been partially covered), along with all of Colorado, Idaho, New Mexico, Montana, and Guam. Under the legislation, the program also would expand to cover some uranium workers who were on the job after 1971 and residents exposed to nuclear waste in Kentucky, Missouri, and Tennessee.

In March, the new legislation easily passed the US Senate by a vote of 69-30, with support from both political parties — but the Republican-led House hasn’t taken it up. As a result, the Radiation Exposure Compensation Act expired in June, and no one can submit new applications for compensation.

A spokesman for House Speaker Mike Johnson told Missouri Independent “unfortunately, the current Senate bill is estimated to cost $50-$60 billion in new mandatory spending with no offsets and was supported by only 20 of 49 Republicans in the Senate.”

Adams rejected these arguments. “The government spends literally trillions of dollars on our nuclear weapons. Whether or not you support that spending, the human cost of building those weapons should be factored in,” she said. She added that she hopes the House will act by the end of the year to pass the bill, but that’s uncertain.
 

As Compensation Is On Hold, Medical Screening Continues

A major benefit is still available for downwinders and uranium workers: Free medical screening and referrals for medical treatment. The Radiation Exposure Screening and Education Program’s funding has not been affected by the congressional impasse, so screenings are continuing for eligible people exposed to radiation.

Radiation exposure clinics offer screening in Arizona, Colorado, Nevada, New Mexico, and Utah, and health providers can get funding to offer screening in other affected states.

In Nevada, “we hold screening clinics throughout the state: Caliente, Ely, and Winnemucca. Also, in Reno and Las Vegas, which are not in designated downwind areas, but many downwinders have migrated there,” said Shaw in an interview. Among downwinders, “our youngest patients are in their 60s and range up to a few in their 90s,” she said.

Patients fill out questionnaires that ask about their medical problems, family history, and medications. “Ely patients in particular seem to have extensive family histories of cancer, and this may be due to their location directly downwind of the Nevada Test Site,” Shaw said. (Ely is a remote town in central eastern Nevada near the Utah border.)

The screenings cover both cancer and noncancer conditions. Shaw said clinicians often diagnose problems other than the covered cancers — new cases of atrial fibrillation, diabetes, and hypertension. “We see a ton of prostate and skin cancer” but don’t make patients eligible for the compensation program because they’re not covered, she said.

Even as compensation is on hold, doctors can get the word out that screenings are still available, Shaw said. “We continue to get contacted by individuals who in these communities who have never heard of this program, even though we’ve been holding clinics since 2005,” Shaw said. “Despite outreach activities and advertising through newspapers and radio, we find the most successful method of reaching these patients is through word of mouth — either from other patients or their doctors. That is why we feel it is so important to reach other physicians as well.”
 

Affected Patients Don’t Just Live in the West

On the outreach front, clinicians in states outside of the western US region can be helpful, too. Shaw urged oncologists nationwide to ask older patients where they lived in the 1950s and 1960s. “Did they live in Nevada, Arizona, Utah, and other Western states that are downwind? They may qualify for needed services and future compensation.”

With regard to compensation, she noted that applicants need to prove that they lived in affected areas many decades ago. And, of course, they must prove that they’ve had cancer. Locating residency records “has often been an enormous challenge.” Old utility bills, pay stubs, and high school annuals can be helpful, “but these records tend to disappear. People and their families throw stuff away.”

Even proving a cancer diagnosis can be a challenge because records can be missing. In Nevada, the law says clinicians only need to keep medical records for 5 years, Shaw said. “Imaging and pathology reports are destroyed. Patients that have been diagnosed with cancer can’t prove it.”

Shaw said she hopes oncologists will offer these messages to patients: “Be an advocate for your own health and keep copies of your own records. Discuss your diagnosis with your family and contact a cancer registry if you are diagnosed with cancer.”

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.

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.

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.

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.

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.

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.

Clonal hematopoiesis of indeterminate potential (CHIP) and mosaic chromosomal alterations (mCAs) are associated with an increased risk for breast cancer, and CHIP is associated with increased mortality in patients with colon cancer, according to the authors of new research.

These findings, drawn from almost 11,000 patients in the Women’s Health Initiative (WHI) study, add further evidence that CHIP and mCA drive solid tumor risk, alongside known associations with hematologic malignancies, reported lead author Pinkal Desai, MD, associate professor of medicine and clinical director of molecular aging at Englander Institute for Precision Medicine, Weill Cornell Medical College, New York City, and colleagues.
 

How This Study Differs From Others of Breast Cancer Risk Factors

“The independent effect of CHIP and mCA on risk and mortality from solid tumors has not been elucidated due to lack of detailed data on mortality outcomes and risk factors,” the investigators wrote in Cancer, although some previous studies have suggested a link.

In particular, the investigators highlighted a 2022 UK Biobank study, which reported an association between CHIP and lung cancer and a borderline association with breast cancer that did not quite reach statistical significance.

But the UK Biobank study was confined to a UK population, Dr. Desai noted in an interview, and the data were less detailed than those in the present investigation.

“In terms of risk, the part that was lacking in previous studies was a comprehensive assessment of risk factors that increase risk for all these cancers,” Dr. Desai said. “For example, for breast cancer, we had very detailed data on [participants’] Gail risk score, which is known to impact breast cancer risk. We also had mammogram data and colonoscopy data.”

In an accompanying editorial, Koichi Takahashi, MD, PhD , and Nehali Shah, BS, of The University of Texas MD Anderson Cancer Center, Houston, Texas, pointed out the same UK Biobank findings, then noted that CHIP has also been linked with worse overall survival in unselected cancer patients. Still, they wrote, “the impact of CH on cancer risk and mortality remains controversial due to conflicting data and context‐dependent effects,” necessitating studies like this one by Dr. Desai and colleagues.
 

How Was the Relationship Between CHIP, MCA, and Solid Tumor Risk Assessed?

To explore possible associations between CHIP, mCA, and solid tumors, the investigators analyzed whole genome sequencing data from 10,866 women in the WHI, a multi-study program that began in 1992 and involved 161,808 women in both observational and clinical trial cohorts.

In 2002, the first big data release from the WHI suggested that hormone replacement therapy (HRT) increased breast cancer risk, leading to widespread reduction in HRT use.

More recent reports continue to shape our understanding of these risks, suggesting differences across cancer types. For breast cancer, the WHI data suggested that HRT-associated risk was largely driven by formulations involving progesterone and estrogen, whereas estrogen-only formulations, now more common, are generally considered to present an acceptable risk profile for suitable patients.

The new study accounted for this potential HRT-associated risk, including by adjusting for patients who received HRT, type of HRT received, and duration of HRT received. According to Desai, this approach is commonly used when analyzing data from the WHI, nullifying concerns about the potentially deleterious effects of the hormones used in the study.

“Our question was not ‘does HRT cause cancer?’ ” Dr. Desai said in an interview. “But HRT can be linked to breast cancer risk and has a potential to be a confounder, and hence the above methodology.

“So I can say that the confounding/effect modification that HRT would have contributed to in the relationship between exposure (CH and mCA) and outcome (cancer) is well adjusted for as described above. This is standard in WHI analyses,” she continued.

“Every Women’s Health Initiative analysis that comes out — not just for our study — uses a standard method ... where you account for hormonal therapy,” Dr. Desai added, again noting that many other potential risk factors were considered, enabling a “detailed, robust” analysis.

Dr. Takahashi and Ms. Shah agreed. “A notable strength of this study is its adjustment for many confounding factors,” they wrote. “The cohort’s well‐annotated data on other known cancer risk factors allowed for a robust assessment of CH’s independent risk.”
 

How Do Findings Compare With Those of the UK Biobank Study?

CHIP was associated with a 30% increased risk for breast cancer (hazard ratio [HR], 1.30; 95% CI, 1.03-1.64; P = .02), strengthening the borderline association reported by the UK Biobank study.

In contrast with the UK Biobank study, CHIP was not associated with lung cancer risk, although this may have been caused by fewer cases of lung cancer and a lack of male patients, Dr. Desai suggested.

“The discrepancy between the studies lies in the risk of lung cancer, although the point estimate in the current study suggested a positive association,” wrote Dr. Takahashi and Ms. Shah.

As in the UK Biobank study, CHIP was not associated with increased risk of developing colorectal cancer.

Mortality analysis, however, which was not conducted in the UK Biobank study, offered a new insight: Patients with existing colorectal cancer and CHIP had a significantly higher mortality risk than those without CHIP. Before stage adjustment, risk for mortality among those with colorectal cancer and CHIP was fourfold higher than those without CHIP (HR, 3.99; 95% CI, 2.41-6.62; P < .001). After stage adjustment, CHIP was still associated with a twofold higher mortality risk (HR, 2.50; 95% CI, 1.32-4.72; P = .004).

The investigators’ first mCA analyses, which employed a cell fraction cutoff greater than 3%, were unfruitful. But raising the cell fraction threshold to 5% in an exploratory analysis showed that autosomal mCA was associated with a 39% increased risk for breast cancer (HR, 1.39; 95% CI, 1.06-1.83; P = .01). No such associations were found between mCA and colorectal or lung cancer, regardless of cell fraction threshold.

The original 3% cell fraction threshold was selected on the basis of previous studies reporting a link between mCA and hematologic malignancies at this cutoff, Dr. Desai said.

She and her colleagues said a higher 5% cutoff might be needed, as they suspected that the link between mCA and solid tumors may not be causal, requiring a higher mutation rate.
 

Why Do Results Differ Between These Types of Studies?

Dr. Takahashi and Ms. Shah suggested that one possible limitation of the new study, and an obstacle to comparing results with the UK Biobank study and others like it, goes beyond population heterogeneity; incongruent findings could also be explained by differences in whole genome sequencing (WGS) technique.

“Although WGS allows sensitive detection of mCA through broad genomic coverage, it is less effective at detecting CHIP with low variant allele frequency (VAF) due to its relatively shallow depth (30x),” they wrote. “Consequently, the prevalence of mCA (18.8%) was much higher than that of CHIP (8.3%) in this cohort, contrasting with other studies using deeper sequencing.” As a result, the present study may have underestimated CHIP prevalence because of shallow sequencing depth.

“This inconsistency is a common challenge in CH population studies due to the lack of standardized methodologies and the frequent reliance on preexisting data not originally intended for CH detection,” Dr. Takahashi and Ms. Shah said.

Even so, despite the “heavily context-dependent” nature of these reported risks, the body of evidence to date now offers a convincing biological rationale linking CH with cancer development and outcomes, they added.
 

How Do the CHIP- and mCA-associated Risks Differ Between Solid Tumors and Blood Cancers?

“[These solid tumor risks are] not causal in the way CHIP mutations are causal for blood cancers,” Dr. Desai said. “Here we are talking about solid tumor risk, and it’s kind of scattered. It’s not just breast cancer ... there’s also increased colon cancer mortality. So I feel these mutations are doing something different ... they are sort of an added factor.”

Specific mechanisms remain unclear, Dr. Desai said, although she speculated about possible impacts on the inflammatory state or alterations to the tumor microenvironment.

“These are blood cells, right?” Dr. Desai asked. “They’re everywhere, and they’re changing something inherently in these tumors.”
 

Future research and therapeutic development

Siddhartha Jaiswal, MD, PhD, assistant professor in the Department of Pathology at Stanford University in California, whose lab focuses on clonal hematopoiesis, said the causality question is central to future research.

“The key question is, are these mutations acting because they alter the function of blood cells in some way to promote cancer risk, or is it reflective of some sort of shared etiology that’s not causal?” Dr. Jaiswal said in an interview.

Available data support both possibilities.

On one side, “reasonable evidence” supports the noncausal view, Dr. Jaiswal noted, because telomere length is one of the most common genetic risk factors for clonal hematopoiesis and also for solid tumors, suggesting a shared genetic factor. On the other hand, CHIP and mCA could be directly protumorigenic via conferred disturbances of immune cell function.

When asked if both causal and noncausal factors could be at play, Dr. Jaiswal said, “yeah, absolutely.”

The presence of a causal association could be promising from a therapeutic standpoint.

“If it turns out that this association is driven by a direct causal effect of the mutations, perhaps related to immune cell function or dysfunction, then targeting that dysfunction could be a therapeutic path to improve outcomes in people, and there’s a lot of interest in this,” Dr. Jaiswal said. He went on to explain how a trial exploring this approach via interleukin-8 inhibition in lung cancer fell short.

Yet earlier intervention may still hold promise, according to experts.

“[This study] provokes the hypothesis that CH‐targeted interventions could potentially reduce cancer risk in the future,” Dr. Takahashi and Ms. Shah said in their editorial.

The WHI program is funded by the National Heart, Lung, and Blood Institute; National Institutes of Health; and the Department of Health & Human Services. The investigators disclosed relationships with Eli Lilly, AbbVie, Celgene, and others. Dr. Jaiswal reported stock equity in a company that has an interest in clonal hematopoiesis.

A version of this article first appeared on Medscape.com.

Clonal hematopoiesis of indeterminate potential (CHIP) and mosaic chromosomal alterations (mCAs) are associated with an increased risk for breast cancer, and CHIP is associated with increased mortality in patients with colon cancer, according to the authors of new research.

These findings, drawn from almost 11,000 patients in the Women’s Health Initiative (WHI) study, add further evidence that CHIP and mCA drive solid tumor risk, alongside known associations with hematologic malignancies, reported lead author Pinkal Desai, MD, associate professor of medicine and clinical director of molecular aging at Englander Institute for Precision Medicine, Weill Cornell Medical College, New York City, and colleagues.
 

How This Study Differs From Others of Breast Cancer Risk Factors

“The independent effect of CHIP and mCA on risk and mortality from solid tumors has not been elucidated due to lack of detailed data on mortality outcomes and risk factors,” the investigators wrote in Cancer, although some previous studies have suggested a link.

In particular, the investigators highlighted a 2022 UK Biobank study, which reported an association between CHIP and lung cancer and a borderline association with breast cancer that did not quite reach statistical significance.

But the UK Biobank study was confined to a UK population, Dr. Desai noted in an interview, and the data were less detailed than those in the present investigation.

“In terms of risk, the part that was lacking in previous studies was a comprehensive assessment of risk factors that increase risk for all these cancers,” Dr. Desai said. “For example, for breast cancer, we had very detailed data on [participants’] Gail risk score, which is known to impact breast cancer risk. We also had mammogram data and colonoscopy data.”

In an accompanying editorial, Koichi Takahashi, MD, PhD , and Nehali Shah, BS, of The University of Texas MD Anderson Cancer Center, Houston, Texas, pointed out the same UK Biobank findings, then noted that CHIP has also been linked with worse overall survival in unselected cancer patients. Still, they wrote, “the impact of CH on cancer risk and mortality remains controversial due to conflicting data and context‐dependent effects,” necessitating studies like this one by Dr. Desai and colleagues.
 

How Was the Relationship Between CHIP, MCA, and Solid Tumor Risk Assessed?

To explore possible associations between CHIP, mCA, and solid tumors, the investigators analyzed whole genome sequencing data from 10,866 women in the WHI, a multi-study program that began in 1992 and involved 161,808 women in both observational and clinical trial cohorts.

In 2002, the first big data release from the WHI suggested that hormone replacement therapy (HRT) increased breast cancer risk, leading to widespread reduction in HRT use.

More recent reports continue to shape our understanding of these risks, suggesting differences across cancer types. For breast cancer, the WHI data suggested that HRT-associated risk was largely driven by formulations involving progesterone and estrogen, whereas estrogen-only formulations, now more common, are generally considered to present an acceptable risk profile for suitable patients.

The new study accounted for this potential HRT-associated risk, including by adjusting for patients who received HRT, type of HRT received, and duration of HRT received. According to Desai, this approach is commonly used when analyzing data from the WHI, nullifying concerns about the potentially deleterious effects of the hormones used in the study.

“Our question was not ‘does HRT cause cancer?’ ” Dr. Desai said in an interview. “But HRT can be linked to breast cancer risk and has a potential to be a confounder, and hence the above methodology.

“So I can say that the confounding/effect modification that HRT would have contributed to in the relationship between exposure (CH and mCA) and outcome (cancer) is well adjusted for as described above. This is standard in WHI analyses,” she continued.

“Every Women’s Health Initiative analysis that comes out — not just for our study — uses a standard method ... where you account for hormonal therapy,” Dr. Desai added, again noting that many other potential risk factors were considered, enabling a “detailed, robust” analysis.

Dr. Takahashi and Ms. Shah agreed. “A notable strength of this study is its adjustment for many confounding factors,” they wrote. “The cohort’s well‐annotated data on other known cancer risk factors allowed for a robust assessment of CH’s independent risk.”

A few years after moving with her family from Iraq to the United States, Areej El-Jawahri, MD, entered the University of Michigan with plans to study law. Then her close friend was diagnosed with terminal cancer. This friend’s wrenching experiences during her final days convinced Dr. El-Jawahri to follow a new career path, one devoted to healing. Today, she practices hematology at Massachusetts General Hospital, Boston, and is a leading advocate for palliative care in oncology.

In an interview, Dr. El-Jawahri spoke about her journey from Baghdad to Boston and the future of palliative medicine in hematology.

Question: Where did you grow up?

Dr. El-Jawahri: My family is from Baghdad, Iraq, and I was born there. We moved to the States when I was 14. I came to Michigan not speaking a word of English. My parents — my father is a mechanical engineer, and my mom is a computer engineer — chose to live in a very white neighborhood in Farmington Hills, in the suburbs of Detroit. The neighborhood did not have any immigrants or Arab Americans. There are a lot of Arab Americans in Michigan, but they chose for me not to hang out with them early on so that I could learn the language. It was a really good choice.

Question: What happened to your college friend?

Dr. El-Jawahri: She had a brain tumor and ended up receiving intensive care at the end of life. We had a lot of conversations about her wishes and desires, but none of those were honored. Her ending was not something that she wanted, nor did it honor her memory.

Question: What do you think went wrong?

Dr. El-Jawahri: She was getting treatment for her family’s sake. The idea of losing her was too hard for them. I remember vividly the conversations where she would say, “I just hope I don’t end up in the hospital at the end of life.” We had that conversation explicitly. But because we were young, her family was very involved in her care. A lot of the decision-making was very complicated.

Question: How did this experience change your career path?

Dr. El-Jawahri: I went into medicine specifically to become an oncologist and cure cancer. The naive 20-year-old in me said, “Nobody should die this miserable death. I’m going to go in, and I’m going to cure it.”

Question: How did palliative medicine become your major focus?

Dr. El-Jawahri: During my first year at Harvard Medical School, I took a course that’s called “Living With Life-Threatening Illness.” It allows medical students to spend their entire first year getting to know a patient living with a serious illness. We’d spend weekly coffee or lunch breaks with them, where we’d hear about their experiences. After every weekly meeting with a patient, we also had a group meeting with several students and group facilitators to talk about — and process — the interactions we had with patients. I was assigned a woman who was living with metastatic breast cancer. I was also introduced to the field of palliative care and how it helps patients manage complex symptoms and process and cope with a difficult diagnosis. It also cultivates the understanding to make informed decisions about their care. That’s when I knew what I wanted to do for the rest of my life — figure out ways to integrate these palliative and supportive care concepts and improve the lived experience of patients and families within the oncology setting.

Question: What happened next?

Dr. El-Jawahri: When I was a first-year intern, I went to residency at Massachusetts General Hospital. I was on an oncology service and admitted a young college student who was diagnosed with acute myeloid leukemia. She was an athlete, and every time she went up the stairs to her dorm, she was getting very short of breath. She went to a walk-in clinic because when you’re 20 and you’re healthy, you don’t think you need anything. They did some blood work, and 2 hours later, they called her and said, “You probably have leukemia. You need to go to the emergency department immediately.” There she saw an emergency doctor who said, “You will be admitted to the hospital. You have leukemia. I’m calling an oncologist, and you’ll probably have to start chemotherapy within the next day or two.”

Question: What was that experience like for the patient?

Dr. El-Jawahri: I’ve never seen someone so scared. The first question she asked me was about her family, who were from North Carolina. She said, “It feels like everybody thinks that I’m dying. Do you think my family will have time to get here?” They were in a car driving over. This is not a unique story in this population. Unfortunately, these patients experience the most traumatic way of being diagnosed and probably the most traumatic experience in oncology. They’re being abducted into a hospital environment, losing all control and starting immediate therapy. Then, for the first 4-6 weeks, they experience immense toxicity, side effects like nausea, vomiting, diarrhea, and mucositis, where they have painful mouth and throat sores that require intravenous pain medications. This causes real posttraumatic stress. After seeing that woman, I made the decision to work in leukemia and transplants to try to make things a little bit better for these patients.

Question: How did the patient fare?

Dr. El-Jawahri: She actually did great and was cured of her disease. Many of our patients with leukemia, especially younger ones, do well in terms of survival. But they struggle with the trauma of their diagnosis and the distress of the acute treatment period. Even in the curative setting, helping patients to cope with a traumatic diagnosis can have a big impact on their quality of life, how they feel, and their long-term outcomes in terms of psychological stress, depression, anxiety, and posttraumatic stress. But so often, our patients with leukemia are not offered palliative care and supportive care because they’re going to be cured.

Question: What is an important lesson from your research into palliative care in hematology?

Dr. El-Jawahri: We can make things better for patients and families by integrating palliative care clinicians into the care of patients. Patients receiving palliative care are more likely to document their end-of-life preferences and discuss them with their clinicians, and they’re less likely to be hospitalized at the end of life. When you ask patients with cancer where do they want to die, many of patients say, “I want to die at home. I don’t want to be in a hospital.” A lot of the work I’m doing now is focused on creating digital apps with components of palliative care and supportive care interventions. Patients can administer these interventions to themselves and learn how to effectively cope and deal with their illness. Some patients may do well with a digital app, but others may actually need the in-person touch. Some may need a hybrid approach. One of the other future directions for us is thinking about how we optimize supportive care interventions. Which ones do we give to which patient?

Question: Considering all that you’ve learned since college, how do you think your sick friend should have been treated?

Dr. El-Jawahri: She was neither introduced to the term palliative care nor to palliative care specialists. Now the standard of care — especially in patients with advanced cancer — is to integrate palliative care clinicians early in the course of illness. We would have loved for her to have a palliative care clinician who didn’t replace the oncologist but rather helped the patient, family, and oncologist communicate more effectively with one another. We hear all the time from patients who say different things to their oncologist than to their palliative care clinician. It’s not like my friend wasn’t able to communicate with her oncologist. But maybe part of it was that she wanted to not disappoint her oncologist [by ending treatment].

Question: Could you tell me about the research you presented at ASCO 2024 regarding 115 adult patients with acute myeloid leukemia and high-risk myelodysplastic syndrome who were receiving non-intensive chemotherapy?

Dr. El-Jawahri: These patients receive therapy that requires frequent clinic visits and often substantially impairs their quality of life. We know this population often does not engage in any timely discussion with their clinicians about their end-of-life care preferences. This multisite randomized clinical trial assigned patients to receive usual oncology care [with palliative care consultations only upon request] vs to see palliative care clinicians monthly in the outpatient setting and twice weekly every time they were hospitalized. The intervention focused on how to help patients manage their symptoms and end-of-life communication in particular. The primary outcome of the study was time from the documentation of end-of-life care preferences to death.

Question: What did you learn?

Dr. El-Jawahri: This is one of the first studies to highlight the impact of palliative care integration on end-of-life care preferences and discussions and documentation in this population. Patients receiving the palliative care intervention were much more likely to discuss their end-of-life care preferences (96.5% vs 68.4%; P < .001). More importantly, those receiving the intervention had a much longer time from documentation of end-of-life care preferences to death. On average, patients in the palliative care intervention group vs the usual care group had a mean of 41 vs 1.5 days from documentation of their preferences to death (P < .001). In the intervention group, these conversations were happening early enough for patients to plan, talk to their families, and discuss their wishes. In the usual care group, they were happening acutely while these patients were dying. We also learned that patients receiving palliative care intervention were less likely to be hospitalized at the end of life (70.6% vs 91.9%; P = .031) and had better quality of life (138.6 vs 125.5; P = .010).

Question: What’s next for your research in this area?

Dr. El-Jawahri: We are doing a large-scale randomized, comparative effectiveness trial of specialty palliative care vs primary palliative care in 11,150 patients with acute myeloid leukemia across 20 institutions in the United States. We expect results in 2028.

Question: What are you hoping to understand?

Dr. El-Jawahri: We will never have enough specialty palliative care clinicians to take care of all patients with serious illness. As a result, we have to learn how palliative care works: How does it improve outcomes? How do we potentially take what palliative care clinicians do and try to integrate it into regular oncology practice? A lot of the work that I’m excited about now regards what we call primary palliative care. How do we train oncology clinicians to incorporate palliative care skills in their practices so we’re able to better meet the needs of our patients and their families? What we’d love to understand from future research is which patient populations need specialty palliative care and which patients can do just fine with an oncology clinician who has a lot of good palliative care skills integrated into their practice.

A few years after moving with her family from Iraq to the United States, Areej El-Jawahri, MD, entered the University of Michigan with plans to study law. Then her close friend was diagnosed with terminal cancer. This friend’s wrenching experiences during her final days convinced Dr. El-Jawahri to follow a new career path, one devoted to healing. Today, she practices hematology at Massachusetts General Hospital, Boston, and is a leading advocate for palliative care in oncology.

In an interview, Dr. El-Jawahri spoke about her journey from Baghdad to Boston and the future of palliative medicine in hematology.

Question: Where did you grow up?

Dr. El-Jawahri: My family is from Baghdad, Iraq, and I was born there. We moved to the States when I was 14. I came to Michigan not speaking a word of English. My parents — my father is a mechanical engineer, and my mom is a computer engineer — chose to live in a very white neighborhood in Farmington Hills, in the suburbs of Detroit. The neighborhood did not have any immigrants or Arab Americans. There are a lot of Arab Americans in Michigan, but they chose for me not to hang out with them early on so that I could learn the language. It was a really good choice.

Question: What happened to your college friend?

Dr. El-Jawahri: She had a brain tumor and ended up receiving intensive care at the end of life. We had a lot of conversations about her wishes and desires, but none of those were honored. Her ending was not something that she wanted, nor did it honor her memory.

Question: What do you think went wrong?

Dr. El-Jawahri: She was getting treatment for her family’s sake. The idea of losing her was too hard for them. I remember vividly the conversations where she would say, “I just hope I don’t end up in the hospital at the end of life.” We had that conversation explicitly. But because we were young, her family was very involved in her care. A lot of the decision-making was very complicated.

Question: How did this experience change your career path?

Dr. El-Jawahri: I went into medicine specifically to become an oncologist and cure cancer. The naive 20-year-old in me said, “Nobody should die this miserable death. I’m going to go in, and I’m going to cure it.”

Question: How did palliative medicine become your major focus?

Dr. El-Jawahri: During my first year at Harvard Medical School, I took a course that’s called “Living With Life-Threatening Illness.” It allows medical students to spend their entire first year getting to know a patient living with a serious illness. We’d spend weekly coffee or lunch breaks with them, where we’d hear about their experiences. After every weekly meeting with a patient, we also had a group meeting with several students and group facilitators to talk about — and process — the interactions we had with patients. I was assigned a woman who was living with metastatic breast cancer. I was also introduced to the field of palliative care and how it helps patients manage complex symptoms and process and cope with a difficult diagnosis. It also cultivates the understanding to make informed decisions about their care. That’s when I knew what I wanted to do for the rest of my life — figure out ways to integrate these palliative and supportive care concepts and improve the lived experience of patients and families within the oncology setting.

Question: What happened next?

Dr. El-Jawahri: When I was a first-year intern, I went to residency at Massachusetts General Hospital. I was on an oncology service and admitted a young college student who was diagnosed with acute myeloid leukemia. She was an athlete, and every time she went up the stairs to her dorm, she was getting very short of breath. She went to a walk-in clinic because when you’re 20 and you’re healthy, you don’t think you need anything. They did some blood work, and 2 hours later, they called her and said, “You probably have leukemia. You need to go to the emergency department immediately.” There she saw an emergency doctor who said, “You will be admitted to the hospital. You have leukemia. I’m calling an oncologist, and you’ll probably have to start chemotherapy within the next day or two.”

Question: What was that experience like for the patient?

Dr. El-Jawahri: I’ve never seen someone so scared. The first question she asked me was about her family, who were from North Carolina. She said, “It feels like everybody thinks that I’m dying. Do you think my family will have time to get here?” They were in a car driving over. This is not a unique story in this population. Unfortunately, these patients experience the most traumatic way of being diagnosed and probably the most traumatic experience in oncology. They’re being abducted into a hospital environment, losing all control and starting immediate therapy. Then, for the first 4-6 weeks, they experience immense toxicity, side effects like nausea, vomiting, diarrhea, and mucositis, where they have painful mouth and throat sores that require intravenous pain medications. This causes real posttraumatic stress. After seeing that woman, I made the decision to work in leukemia and transplants to try to make things a little bit better for these patients.

Question: How did the patient fare?

Dr. El-Jawahri: She actually did great and was cured of her disease. Many of our patients with leukemia, especially younger ones, do well in terms of survival. But they struggle with the trauma of their diagnosis and the distress of the acute treatment period. Even in the curative setting, helping patients to cope with a traumatic diagnosis can have a big impact on their quality of life, how they feel, and their long-term outcomes in terms of psychological stress, depression, anxiety, and posttraumatic stress. But so often, our patients with leukemia are not offered palliative care and supportive care because they’re going to be cured.

Question: What is an important lesson from your research into palliative care in hematology?

Dr. El-Jawahri: We can make things better for patients and families by integrating palliative care clinicians into the care of patients. Patients receiving palliative care are more likely to document their end-of-life preferences and discuss them with their clinicians, and they’re less likely to be hospitalized at the end of life. When you ask patients with cancer where do they want to die, many of patients say, “I want to die at home. I don’t want to be in a hospital.” A lot of the work I’m doing now is focused on creating digital apps with components of palliative care and supportive care interventions. Patients can administer these interventions to themselves and learn how to effectively cope and deal with their illness. Some patients may do well with a digital app, but others may actually need the in-person touch. Some may need a hybrid approach. One of the other future directions for us is thinking about how we optimize supportive care interventions. Which ones do we give to which patient?

Question: Considering all that you’ve learned since college, how do you think your sick friend should have been treated?

Dr. El-Jawahri: She was neither introduced to the term palliative care nor to palliative care specialists. Now the standard of care — especially in patients with advanced cancer — is to integrate palliative care clinicians early in the course of illness. We would have loved for her to have a palliative care clinician who didn’t replace the oncologist but rather helped the patient, family, and oncologist communicate more effectively with one another. We hear all the time from patients who say different things to their oncologist than to their palliative care clinician. It’s not like my friend wasn’t able to communicate with her oncologist. But maybe part of it was that she wanted to not disappoint her oncologist [by ending treatment].

Question: Could you tell me about the research you presented at ASCO 2024 regarding 115 adult patients with acute myeloid leukemia and high-risk myelodysplastic syndrome who were receiving non-intensive chemotherapy?

Dr. El-Jawahri: These patients receive therapy that requires frequent clinic visits and often substantially impairs their quality of life. We know this population often does not engage in any timely discussion with their clinicians about their end-of-life care preferences. This multisite randomized clinical trial assigned patients to receive usual oncology care [with palliative care consultations only upon request] vs to see palliative care clinicians monthly in the outpatient setting and twice weekly every time they were hospitalized.

Each year in the United States, approximately 1.7 million Americans are diagnosed with a potentially lethal malignancy. Typical therapies of choice include surgery, radiation, and occasionally, toxic chemotherapy (chemo) — approaches that eliminate the cancer in about 1,000,000 of these cases. The remaining 700,000 or so often proceed to chemotherapy either immediately or upon cancer recurrence, spread, or newly recognized metastases. “Cures” after that point are rare.

I’m speaking in generalities, understanding that each cancer and each patient is unique.
 

Chemotherapy

Chemotherapy alone can cure a small number of cancer types. When added to radiation or surgery, chemotherapy can help to cure a wider range of cancer types. As an add-on, chemotherapy can extend the length and quality of life for many patients with cancer. Since chemotherapy is by definition “toxic,” it can also shorten the duration or harm the quality of life and provide false hope. The Table summarizes what chemotherapy can and cannot achieve in selected cancer types.

• Lack of response (the tumor failed to shrink).
• Progression (the cancer may have grown or spread further).
• Adverse side effects were too severe to continue.

The drugs used in second-line chemo will typically be different from those used in first line, sometimes because cancer cells can develop resistance to chemotherapy drugs over time. Moreover, the goal of second-line chemo may differ from that of first-line therapy. Rather than chiefly aiming for a cure, second-line treatment might focus on slowing cancer growth, managing symptoms, or improving quality of life. Unfortunately, not every type of cancer has a readily available second-line option.

Third-line treatment. Third-line options come into play when both the initial course of chemo (first line) and the subsequent treatment (second line) have failed to achieve remission or control the cancer’s spread. Owing to the progressive nature of advanced cancers, patients might not be eligible or healthy enough for third-line therapy. Depending on cancer type, the patient’s general health, and response to previous treatments, third-line options could include:

• New or different chemotherapy drugs compared with prior lines.
• Surgery to debulk the tumor.
• Radiation for symptom control.
• Targeted therapy: drugs designed to target specific vulnerabilities in cancer cells.
• Immunotherapy: agents that help the body’s immune system fight cancer cells.
• Clinical trials testing new or investigational treatments, which may be applicable at any time, depending on the questions being addressed.

The goals of third-line therapy may shift from aiming for a cure to managing symptoms, improving quality of life, and potentially slowing cancer growth. The decision to pursue third-line therapy involves careful consideration by the doctor and patient, weighing the potential benefits and risks of treatment considering the individual’s overall health and specific situation.

It’s important to have realistic expectations about the potential outcomes of third-line therapy. Although remission may be unlikely, third-line therapy can still play a role in managing the disease.

Navigating advanced cancer treatment is very complex. The patient and physician must together consider detailed explanations and clarifications to set expectations and make informed decisions about care.
 

Interventions to Consider Earlier

In traditional clinical oncology practice, other interventions are possible, but these may not be offered until treatment has reached the third line:

• Molecular testing.
• Palliation.
• Clinical trials.
• Innovative testing to guide targeted therapy by ascertaining which agents are most likely (or not likely at all) to be effective.

I would argue that the patient’s interests are better served by considering and offering these other interventions much earlier, even before starting first-line chemotherapy.

Molecular testing. The best time for molecular testing of a new malignant tumor is typically at the time of diagnosis. Here’s why:

• Molecular testing helps identify specific genetic mutations in the cancer cells. This information can be crucial for selecting targeted therapies that are most effective against those specific mutations. Early detection allows for the most treatment options. For example, for non–small cell lung cancer, early is best because treatment and outcomes may well be changed by test results.
• Knowing the tumor’s molecular makeup can help determine whether a patient qualifies for clinical trials of new drugs designed for specific mutations.
• Some molecular markers can offer information about the tumor’s aggressiveness and potential for metastasis so that prognosis can be informed.

Molecular testing can be a valuable tool throughout a cancer patient’s journey. With genetically diverse tumors, the initial biopsy might not capture the full picture. Molecular testing of circulating tumor DNA can be used to monitor a patient’s response to treatment and detect potential mutations that might arise during treatment resistance. Retesting after metastasis can provide additional information that can aid in treatment decisions.

Palliative care. The ideal time to discuss palliative care with a patient with cancer is early in the diagnosis and treatment process. Palliative care is not the same as hospice care; it isn’t just about end-of-life. Palliative care focuses on improving a patient’s quality of life throughout cancer treatment. Palliative care specialists can address a wide range of symptoms a patient might experience from cancer or its treatment, including pain, fatigue, nausea, and anxiety.

Early discussions allow for a more comprehensive care plan. Open communication about all treatment options, including palliative care, empowers patients to make informed decisions about their care goals and preferences.

Specific situations where discussing palliative care might be appropriate are:

• Soon after a cancer diagnosis.
• If the patient experiences significant side effects from cancer treatment.
• When considering different treatment options, palliative care can complement those treatments.
• In advanced stages of cancer, to focus on comfort and quality of life.

Clinical trials. Participation in a clinical trial to explore new or investigational treatments should always be considered.

In theory, clinical trials should be an option at any time in the patient’s course. But the organized clinical trial experience may not be available or appropriate. Then, the individual becomes a de facto “clinical trial with an n of 1.” Read this brief open-access blog post at Cancer Commons to learn more about that circumstance.

Innovative testing. The best choice of chemotherapeutic or targeted therapies is often unclear. The clinician is likely to follow published guidelines, often from the National Comprehensive Cancer Network.

These are evidence based and driven by consensus of experts. But guideline-recommended therapy is not always effective, and weeks or months can pass before this ineffectiveness becomes apparent. Thus, many researchers and companies are seeking methods of testing each patient’s specific cancer to determine in advance, or very quickly, whether a particular drug is likely to be effective.

Navigating advanced cancer treatment is very complex. The patient and physician must together consider detailed explanations and clarifications to set expectations and make informed decisions about care.
 

Interventions to Consider Earlier

In traditional clinical oncology practice, other interventions are possible, but these may not be offered until treatment has reached the third line:

• Molecular testing.
• Palliation.
• Clinical trials.
• Innovative testing to guide targeted therapy by ascertaining which agents are most likely (or not likely at all) to be effective.

I would argue that the patient’s interests are better served by considering and offering these other interventions much earlier, even before starting first-line chemotherapy.

Molecular testing. The best time for molecular testing of a new malignant tumor is typically at the time of diagnosis. Here’s why:

• Molecular testing helps identify specific genetic mutations in the cancer cells. This information can be crucial for selecting targeted therapies that are most effective against those specific mutations. Early detection allows for the most treatment options. For example, for non–small cell lung cancer, early is best because treatment and outcomes may well be changed by test results.
• Knowing the tumor’s molecular makeup can help determine whether a patient qualifies for clinical trials of new drugs designed for specific mutations.
• Some molecular markers can offer information about the tumor’s aggressiveness and potential for metastasis so that prognosis can be informed.

Molecular testing can be a valuable tool throughout a cancer patient’s journey. With genetically diverse tumors, the initial biopsy might not capture the full picture. Molecular testing of circulating tumor DNA can be used to monitor a patient’s response to treatment and detect potential mutations that might arise during treatment resistance. Retesting after metastasis can provide additional information that can aid in treatment decisions.

Palliative care. The ideal time to discuss palliative care with a patient with cancer is early in the diagnosis and treatment process. Palliative care is not the same as hospice care; it isn’t just about end-of-life. Palliative care focuses on improving a patient’s quality of life throughout cancer treatment. Palliative care specialists can address a wide range of symptoms a patient might experience from cancer or its treatment, including pain, fatigue, nausea, and anxiety.

Early discussions allow for a more comprehensive care plan. Open communication about all treatment options, including palliative care, empowers patients to make informed decisions about their care goals and preferences.

Specific situations where discussing palliative care might be appropriate are:

• Soon after a cancer diagnosis.
• If the patient experiences significant side effects from cancer treatment.
• When considering different treatment options, palliative care can complement those treatments.
• In advanced stages of cancer, to focus on comfort and quality of life.

Clinical trials. Participation in a clinical trial to explore new or investigational treatments should always be considered.

In theory, clinical trials should be an option at any time in the patient’s course. But the organized clinical trial experience may not be available or appropriate. Then, the individual becomes a de facto “clinical trial with an n of 1.” Read this brief open-access blog post at Cancer Commons to learn more about that circumstance.

Innovative testing. The best choice of chemotherapeutic or targeted therapies is often unclear. The clinician is likely to follow published guidelines, often from the National Comprehensive Cancer Network.

These are evidence based and driven by consensus of experts. But guideline-recommended therapy is not always effective, and weeks or months can pass before this ineffectiveness becomes apparent. Thus, many researchers and companies are seeking methods of testing each patient’s specific cancer to determine in advance, or very quickly, whether a particular drug is likely to be effective.

Each year in the United States, approximately 1.7 million Americans are diagnosed with a potentially lethal malignancy. Typical therapies of choice include surgery, radiation, and occasionally, toxic chemotherapy (chemo) — approaches that eliminate the cancer in about 1,000,000 of these cases. The remaining 700,000 or so often proceed to chemotherapy either immediately or upon cancer recurrence, spread, or newly recognized metastases. “Cures” after that point are rare.

I’m speaking in generalities, understanding that each cancer and each patient is unique.
 

Chemotherapy

Chemotherapy alone can cure a small number of cancer types. When added to radiation or surgery, chemotherapy can help to cure a wider range of cancer types. As an add-on, chemotherapy can extend the length and quality of life for many patients with cancer. Since chemotherapy is by definition “toxic,” it can also shorten the duration or harm the quality of life and provide false hope. The Table summarizes what chemotherapy can and cannot achieve in selected cancer types.

• Lack of response (the tumor failed to shrink).
• Progression (the cancer may have grown or spread further).
• Adverse side effects were too severe to continue.

The drugs used in second-line chemo will typically be different from those used in first line, sometimes because cancer cells can develop resistance to chemotherapy drugs over time. Moreover, the goal of second-line chemo may differ from that of first-line therapy. Rather than chiefly aiming for a cure, second-line treatment might focus on slowing cancer growth, managing symptoms, or improving quality of life. Unfortunately, not every type of cancer has a readily available second-line option.

Third-line treatment. Third-line options come into play when both the initial course of chemo (first line) and the subsequent treatment (second line) have failed to achieve remission or control the cancer’s spread. Owing to the progressive nature of advanced cancers, patients might not be eligible or healthy enough for third-line therapy. Depending on cancer type, the patient’s general health, and response to previous treatments, third-line options could include:

• New or different chemotherapy drugs compared with prior lines.
• Surgery to debulk the tumor.
• Radiation for symptom control.
• Targeted therapy: drugs designed to target specific vulnerabilities in cancer cells.
• Immunotherapy: agents that help the body’s immune system fight cancer cells.
• Clinical trials testing new or investigational treatments, which may be applicable at any time, depending on the questions being addressed.

The goals of third-line therapy may shift from aiming for a cure to managing symptoms, improving quality of life, and potentially slowing cancer growth. The decision to pursue third-line therapy involves careful consideration by the doctor and patient, weighing the potential benefits and risks of treatment considering the individual’s overall health and specific situation.

It’s important to have realistic expectations about the potential outcomes of third-line therapy. Although remission may be unlikely, third-line therapy can still play a role in managing the disease.
