Mixed Topics

The ethical imperative in healthcare necessitates equitable delivery of care to all individuals, regardless of their socio-economic status or insurance coverage. This principle is rooted in the concept of justice and is crucial to achieving health equity.

As gastroenterologists, despite our various practice settings, we have seen the harmful effects of economic and social disparities on health outcomes. We must therefore ensure that we acknowledge the existence of these disparities, and then begin to provide a framework that allows us to ethically and successfully navigate these complexities for our patients and our affiliated structures.

The following cases illustrate the complexities and ethical dilemmas that gastroenterology and hepatology healthcare professionals encounter in delivering care within the traditional healthcare system.

• Case 1: A 44-year-old male presents to the hospital with intermittent rectal bleeding every few weeks without associated abdominal pain or weight loss and not associated with straining. He has bowel movements every 2-3 days. There is no family history of underlying gastrointestinal disease or associated neoplasm. He is accompanied at the time of the interview by his coworker who offered to drive him to the hospital as he is having personal car trouble. Physical examination reveals normal hemodynamics, abdomen is benign, a digital rectal exam reveals small internal hemorrhoids without pain. Hemoglobin is 10, MCV 85. There is scant blood on the glove. He is uninsured. A GI consult is placed to determine the disposition of the patient. The resident on service suggests outpatient follow-up given low risk of clinical deterioration.
• Case 2: A 28-year-old woman postpartum 6 weeks presents in the office with a history of ulcerative colitis which was diagnosed 2 years prior. She was initially placed on steroid therapy. She underwent a colonoscopy at the time of her diagnosis and was following with a gastroenterologist at which time she was found to have moderate left-sided disease with a modified Mayo score of 9. She complains of urgency and rectal bleeding. She saw a gastroenterologist during her pregnancy and was placed on oral mesalamine, which she remains on at the time of evaluation. Once her physical examination is completed and laboratory values are reviewed, you begin to discuss advanced therapies including biologics as she has failed conventional therapies.
• Case 3: You receive a phone call from an outside hospital about a potential transfer for a 46-year-old male who is an immigrant of unknown citizenship status with fulminant liver failure. He meets all criteria including encephalopathy and coagulopathy. He drinks only socially. His secondary liver workup for extensive disease including ceruloplasmin remains pending. Viral hepatology serologies and autoimmune serologies are negative.

Challenges to the Delivery of Equitable Care

These cases underscore the challenges of delivering equitable care within a system that often fails to address the social determinants of health (SDOH). The disparity in the evaluation and treatment of patients based on insurance status not only affects patient outcomes, but also emphasizes the ethical dilemma of balancing cost with population health management.

The introduction of measures SDOH-1 and SDOH-2 by the Centers for Medicare & Medicaid Services in the 2023 IPPS Final Rule is a step towards requiring hospitals to systematically collect patient-level SDOH data, aiming to establish meaningful collaborations between healthcare providers and community-based organizations for whole-person care.¹ The primary goal is to allow ecosystems to collect patient-level social risk factors followed by the creation of meaningful collaboration between healthcare providers and the community-based organizations.

The office settings may or may not implement the SDOH and the current electronic medical record systems. However, from a social history standpoint and certainly from a decision standpoint, the impact of SDOH is realized in all settings.
 

Interplay of SDOH and Ethical Considerations

The recognition of social determinants of health is crucial for ethical healthcare delivery. In the first case, considering the patient’s identified social determinants of health — including lack of insurance and transportation, combined with the rising incidence of colorectal cancer in individuals under 55 — an argument could be made for admitting the patient under observation for inpatient colonoscopy.

Data have shown disparities in treatment and referrals in emergency care setting for Black patients with rectal bleeding.² It is imperative that we recognize these existing disparities in diagnosis and outcomes, along with determining SDOH to appropriately come to a final disposition. This approach aligns with the principle of justice and the imperative to deliver equitable care.

In the third case study, we have a patient facing the life-or-death situation of fulminant liver failure. He requires an expeditious decision to be made about transfer candidacy for liver transplant evaluation by the hepatology team.
 

Impact of Insurance Status on Healthcare Access

Insurance status significantly influences access to healthcare and disparities in treatment outcomes. As seen in case 2 and case 3, our therapies often hinge upon access.

In the inflammatory bowel disease (IBD) case, the therapy that we will choose for our IBD patient may be more influenced by access than efficacy. In a national sample of children with Crohn’s disease, publicly insured children were more likely to receive a biologic within 18 months of diagnosis compared to children with private insurance.³ This would suggest that those with private insurance perhaps experience increased barriers.

In the IBD case that we presented here, we do have a publicly insured woman who will face a potential loss of her Medicaid coverage. Our therapeutic decision will therefore not just rely on risk stratification and individualized approach, but rather the programs that are put in place by our pharmaceutical partners to support a future self-pay patient. This may or may not be favorable to her outcome. This discrepancy points to systemic inequalities in healthcare access and the need for policies that ensure equitable treatment for all, regardless of insurance status.
 

Conclusion

The delivery of care in healthcare is an ethical imperative that demands equity and justice. The cases discussed above illustrate the complex interplay between socioeconomic factors, insurance status, and the ethical challenges in providing equitable care.

Systematic efforts to address social determinants of health, as mandated by recent CMS measures, along with a commitment to ethical principles, are essential steps toward reducing disparities and ensuring that all individuals receive the care they need. As healthcare expenditures continue to rise, particularly in areas like gastrointestinal health, addressing these ethical and systemic challenges becomes even more critical for the sustainability of the healthcare system and the well-being of the population it serves.

Gastrointestinal healthcare expenditures totaled $119.6 billion in 2018. Annually there were more than 36.8 million ambulatory visits for GI symptoms and 43.4 million ambulatory visits with primary GI diagnosis.⁴ The use of higher-acuity settings and lack of continuity of care, and the under-recognition and lack of longitudinal framework to follow those families at risk continue to compromise our healthcare system. We must begin to create a framework to provide equitable care for which the cornerstone should be those identified social determinants of health.

The results of a large French study comparing the cancer risk in children conceived through assisted reproductive technology (ART) with that of naturally conceived children were published recently in JAMA Network Open. This study is one of the largest to date on this subject: It included 8,526,306 children born in France between 2010 and 2021, of whom 260,236 (3%) were conceived through ART, and followed them up to a median age of 6.7 years.

Motivations for the Study

ART (including artificial insemination, in vitro fertilization [IVF], or intracytoplasmic sperm injection [ICSI] with fresh or frozen embryo transfer) accounts for about 1 in 30 births in France. However, limited and heterogeneous data have suggested an increased risk for certain health disorders, including cancer, among children conceived through ART. Therefore, a large-scale evaluation of cancer risk in these children is important.

No Overall Increase

In all, 9256 children developed cancer, including 292 who were conceived through ART. Thus, this study did not show an increased risk for cancer (of all types combined) in children conceived through ART. Nevertheless, a slight increase in the risk for leukemia was observed in children conceived through IVF or ICSI. The investigators observed approximately one additional case for every 5000 newborns conceived through IVF or ICSI who reached age 10 years.

Epidemiological monitoring should be continued to better evaluate long-term risks and see whether the risk for leukemia is confirmed. If it is, then it will be useful to investigate the mechanisms related to ART techniques or the fertility disorders of parents that could lead to an increased risk for leukemia.

Early education is right up there with motherhood and apple pie as unarguable positive concepts. How could exposing young children to a school-like atmosphere not be a benefit, particularly in communities dominated by socioeconomic challenges? While there are some questions about the value of playing Mozart to infants, early education in the traditional sense continues to be viewed as a key strategy for providing young children a preschool foundation on which a successful academic career can be built. Several oft-cited randomized controlled trials have fueled both private and public interest and funding.

However, a recent commentary published in Science suggests that all programs are “not unequivocally positive and much more research is needed.” “Worrisome results in Tennessee,” “Success in Boston,” and “Largely null results for Headstart” are just a few of the article’s section titles and convey a sense of the inconsistency the investigators found as they reviewed early education systems around the country.

Wilkoff_William_G_2_web.jpg

While there may be some politicians who may attempt to use the results of this investigation as a reason to cancel public funding of underperforming early education programs, the authors avoid this baby-and-the-bathwater conclusion. Instead, they urge more rigorous research “to understand how effective programs can be designed and implemented.”

The kind of re-thinking and brainstorming these investigators suggest takes time. While we’re waiting for this process to gain traction, this might be a good time to consider some of the benefits of early education that we don’t usually consider when our focus is on academic metrics.

A recent paper in Children’s Health Care by investigators at the Boston University Medical Center and School of Medicine considered the diet of children attending preschool. Looking at the dietary records of more than 300 children attending 30 childcare centers, the researchers found that the children’s diets before arrival at daycare was less healthy than while they were in daycare. “The hour after pickup appeared to be the least healthful” of any of the time periods surveyed. Of course, we will all conjure up images of what this chaotic post-daycare pickup may look like and cut the harried parents and grandparents some slack when it comes to nutritional choices. However, the bottom line is that for the group of children surveyed being in preschool or daycare protected them from a less healthy diet they were being provided outside of school hours.

Our recent experience with pandemic-related school closures provides more evidence that being in school was superior to any remote experience academically. School-age children and adolescents gained weight when school closures were the norm. Play patterns for children shifted from outdoor play to indoor play — often dominated by more sedentary video games. Both fatal and non-fatal gun-related injuries surged during the pandemic and, by far, the majority of these occur in the home and not at school.

Stepping back to look at this broader picture that includes diet, physical activity, and safety — not to mention the benefits of socialization — leads one to arrive at the unfortunate conclusion that for many children in this country, being at home is considerably less healthy than being in school. Of course there will be those who point to the belief that schools are petri dishes putting children at greater risk for respiratory infections. On the other hand, we must accept that schools haven’t proved to be a major factor in the spread of COVID that many had feared.

The authors of the study in Science are certainly correct in recommending a more thorough investigation into the academic benefits of preschool education. However, we must keep in mind that preschool offers an environment that can be a positive influence on young children.

Dr. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years. He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose.

The kind of re-thinking and brainstorming these investigators suggest takes time. While we’re waiting for this process to gain traction, this might be a good time to consider some of the benefits of early education that we don’t usually consider when our focus is on academic metrics.

A recent paper in Children’s Health Care by investigators at the Boston University Medical Center and School of Medicine considered the diet of children attending preschool. Looking at the dietary records of more than 300 children attending 30 childcare centers, the researchers found that the children’s diets before arrival at daycare was less healthy than while they were in daycare. “The hour after pickup appeared to be the least healthful” of any of the time periods surveyed. Of course, we will all conjure up images of what this chaotic post-daycare pickup may look like and cut the harried parents and grandparents some slack when it comes to nutritional choices. However, the bottom line is that for the group of children surveyed being in preschool or daycare protected them from a less healthy diet they were being provided outside of school hours.

Our recent experience with pandemic-related school closures provides more evidence that being in school was superior to any remote experience academically. School-age children and adolescents gained weight when school closures were the norm. Play patterns for children shifted from outdoor play to indoor play — often dominated by more sedentary video games. Both fatal and non-fatal gun-related injuries surged during the pandemic and, by far, the majority of these occur in the home and not at school.

Stepping back to look at this broader picture that includes diet, physical activity, and safety — not to mention the benefits of socialization — leads one to arrive at the unfortunate conclusion that for many children in this country, being at home is considerably less healthy than being in school. Of course there will be those who point to the belief that schools are petri dishes putting children at greater risk for respiratory infections. On the other hand, we must accept that schools haven’t proved to be a major factor in the spread of COVID that many had feared.

The authors of the study in Science are certainly correct in recommending a more thorough investigation into the academic benefits of preschool education. However, we must keep in mind that preschool offers an environment that can be a positive influence on young children.

Early education is right up there with motherhood and apple pie as unarguable positive concepts. How could exposing young children to a school-like atmosphere not be a benefit, particularly in communities dominated by socioeconomic challenges? While there are some questions about the value of playing Mozart to infants, early education in the traditional sense continues to be viewed as a key strategy for providing young children a preschool foundation on which a successful academic career can be built. Several oft-cited randomized controlled trials have fueled both private and public interest and funding.

However, a recent commentary published in Science suggests that all programs are “not unequivocally positive and much more research is needed.” “Worrisome results in Tennessee,” “Success in Boston,” and “Largely null results for Headstart” are just a few of the article’s section titles and convey a sense of the inconsistency the investigators found as they reviewed early education systems around the country.

Maternal in utero exposure to antibiotics was associated with an increased risk for infantile seborrheic dermatitis (SD) regardless of the mother’s history of SD, but this association was not as strong for childhood-onset SD.

The findings come from a large analysis of data from the United Kingdom that was presented during a late-breaking abstract session at the annual meeting of the Society for Investigative Dermatology.

SD is a common skin disease “that shares similarities with atopic dermatitis or atopic eczema as both are prevalent inflammatory skin diseases that can present with a chronic relapsing, remitting course,” the study’s corresponding author Zelma C. Chiesa Fuxench, MD, MSCE, assistant professor of dermatology at the University of Pennsylvania, Philadelphia, said in an interview. “Like atopic dermatitis, the pathophysiology of seborrheic dermatitis is thought to be complex and involves an interplay between genetics, immune dysregulation, and alterations in lipid composition and the skin microbiome, among others.”

“We observed that antibiotic exposure in utero was primarily associated with an increased risk of infantile SD regardless of the mother’s history of SD, but this association was not as strong for childhood-onset SD,” Dr. Chiesa Fuxench said. “This would suggest that in utero exposure to antibiotics, particularly penicillin, may have its greatest effect on the colonization of skin microbiota in the newborn period leading to the development of infantile SD. Aside from seeking to improve our understanding of the pathophysiology of SD, our findings also suggest that infantile SD and childhood-onset SD may be separate entities with different risk factors, a hypothesis that needs to be further studied.”

She acknowledged certain limitations of the analysis, including the potential for unrecorded diagnoses of SD or misclassified cases in the database. For example, AD and psoriasis “may appear clinically like SD,” she said, although they performed sensitivity analysis excluding patients with these diagnoses and found similar results. In addition, there is the possibility that not all antibiotic exposures were captured in this database, and data on antibiotic exposure may be missing, she added.

Dr. Chiesa Fuxench disclosed that she received research grants from Lilly, LEO Pharma, Regeneron, Sanofi, Tioga, Vanda, and Incyte for work related to AD and from Menlo Therapeutics and Galderma for work related to prurigo nodularis. She has served as a consultant for the Asthma and Allergy Foundation of America, National Eczema Association, AbbVie, Incyte Corporation, and Pfizer and received honoraria for CME work in AD sponsored by education grants from Regeneron/Sanofi and Pfizer and from Beiersdorf for work related to skin cancer and sun protection.

About 45,000 people will descend on Chicago for the American Society of Clinical Oncology (ASCO) annual meeting, starting May 31.

From its origins in 1964, ASCO’s annual event has grown to become the world’s largest clinical oncology meeting, drawing attendees from across the globe.

More than 7000 abstracts were submitted for this year’s meeting a new record — and over 5000 were selected for presentation.

This year’s chair of the Annual Meeting Education Committee, Thomas William LeBlanc, MD, told us he has been attending the meeting since his training days more than a decade ago.

The event is “just incredibly empowering and energizing,” Dr. LeBlanc said, with opportunities to catch up with old colleagues and meet new ones, learn how far oncology has come and where it’s headed, and hear clinical pearls to take back the clinic.

This year’s theme, selected by ASCO President Lynn M. Schuchter, MD, is “The Art and Science of Cancer Care: From Comfort to Cure.” 

Dr. LeBlanc, a blood cancer specialist at Duke University, Durham, North Carolina, said the theme has been woven throughout the abstract and educational sessions. Most sessions will have at least one presentation related to how we support people — not only “when we cure them but also when we can’t cure them,” he said.

Topics will include patient well-being, comfort measures, and survivorship. And for the first time the plenary session will include a palliative care abstract that addresses whether or not palliative care can be delivered effectively through telemedicine. The session is on Sunday, June 2. 

Other potentially practice changing plenary abstracts tackle immunotherapy combinations for resectable melanoma, perioperative chemotherapy vs neoadjuvant chemoradiation for esophageal cancer, and osimertinib after definitive chemoradiotherapy for unresectable non–small cell lung cancer.

ASCO is piloting a slightly different format for research presentations this year. Instead of starting with context and background, speakers have been asked to present study results upfront as well as repeat them at the end of the talk. The reason behind the tweak is that engagement and retention tend to be better when results are presented upfront, instead of just at the end of a talk.

A popular session — ASCO Voices — has also been given a more central position in the conference: Friday, May 31. In this session, speakers will give short presentations about their personal experiences as providers, researchers, or patients.

ASCO Voices is a relatively recent addition to the meeting that has grown and gotten better. The talks are usually “very powerful narratives” that remind clinicians about “the importance of what they’re doing each day,” Dr. LeBlanc said.

Snippets of the talks will be played while people wait for sessions to begin at the meeting, so attendees who miss the Friday talks can still hear them.

In terms of educational sessions, Dr. LeBlanc highlighted two that might be of general interest to practicing oncologists: A joint ASCO/American Association for Cancer Research session entitled “Drugging the ‘Undruggable’ Target: Successes, Challenges, and the Road Ahead,” on Sunday morning and “Common Sense Oncology: Equity, Value, and Outcomes That Matter” on Monday morning.

As a blood cancer specialist, he said he is particularly interested in the topline results from the ASC4FIRST trial of asciminib, a newer kinase inhibitor, in newly diagnosed chronic myeloid leukemia, presented on Friday.

As in past years, this news organization will be on hand providing coverage with a dedicated team of reporters, editors, and videographers. Stop by our exhibit hall booth — number 26030 — to learn about the tools we offer to support your practice.

A new clinical practice guideline by the American Society for Radiation Oncology (ASTRO) steers use of external beam radiation therapy (EBRT) for the palliation of symptomatic bone metastases, including recommendations concerning pain management and quality of life.

The guideline was needed to update previous recommendations and incorporate new high-quality evidence for the management of symptomatic bone metastases, Sara Alcorn, MD, PhD, of the University of Minnesota, Minneapolis, and colleagues wrote in Practical Radiation Oncology.

The focus was on the efficacy of EBRT in reducing pain, improving skeletal function, and enhancing quality of life, they wrote in the clinical practice guideline.

In developing their recommendations, the ASTRO task force reviewed evidence from 53 randomized controlled trials (RCTs) and 31 nonrandomized studies, and considered clinical experience.
 

Indications for Palliative Radiation

EBRT is strongly recommended for reducing pain from osseous metastasis and improving ambulatory status, sphincter function, and reducing pain in patients with spinal metastases causing compression of the spinal cord or cauda equina.

For patients with symptomatic bone metastases and an anticipated life expectancy of at least 4 weeks, EBRT is conditionally recommended to improve quality of life.

Implementation of other Treatments Alongside Palliative Radiation

Instead of RT alone, surgery with postoperative RT is conditionally recommended for patients with compression of the spinal cord or cauda equina.

Postoperative RT is strongly recommended for patients who have undergone surgery for non-spine bone metastases or spine metastases without involving spinal cord or cauda equina compression.

For patients with spinal bone metastases compressing the spinal cord or cauda equina, combining RT with dexamethasone is strongly recommended over RT alone.

Techniques, Dose-Fractionation, and Dose-Constraints for Initial Palliative Radiation

For patients with symptomatic bone metastases undergoing conventional palliative RT, strongly recommended doses are 800 cGy in 1 fraction, 2000 cGy in 5 fractions, 2400 cGy in 6 fractions, or 3000 cGy in 10 fractions.

For patients with spinal bone metastases causing compression of the spinal cord or cauda equina who are not candidates for initial surgical decompression and are treated with conventional palliative RT, strongly recommended doses are 800 cGy in 1 fraction, 1600 cGy in 2 fractions, 2000 cGy in 5 fractions, or 3000 cGy in 10 fractions.

When selecting dose-fractionation, consider patient and disease factors such as prognosis and radiosensitivity, the authors wrote.

Highly conformal planning and delivery techniques, such as intensity-modulated radiation therapy, are conditionally recommended for patients with spinal bone metastases compressing the spinal cord or cauda equina who are receiving dose-escalated palliative RT.

The strongly recommended stereotactic body radiotherapy (SBRT) doses for patients with symptomatic bone metastases are 1200 to 1600 cGy in 1 fraction for non-spine metastases and 2400 cGy in 2 fractions for spine metastases. Other established SBRT dose and fractionation regimens with similar biologically effective doses may be considered based on patient tumor characteristics, normal tissue factors, and physician experience.

For patients with symptomatic bone metastases who have an ECOG PS of 0-2, are not undergoing surgical intervention, and have no neurological symptoms, SBRT is conditionally recommended over conventional palliative RT. Other factors to consider include life expectancy, tumor radiosensitivity, and metastatic disease burden, the guideline says.
 

Techniques, Dose-Fractionation, and Dose-Constraints for Palliative Reirradiation

For patients with spinal bone metastases requiring reirradiation to the same site, the strongly recommended conventional palliative RT regimens are 800 cGy in 1 fraction, 2000 cGy in 5 fractions, 2400 cGy in 6 fractions, or 2000 cGy in 8 fractions. When determining the RT dose-fractionation, consider the prior RT dose, time interval, and total spinal cord tolerance, the guideline says.

Treatment with SBRT is conditionally recommended for patients with spinal bone metastases needing reirradiation at the same site. When determining if SBRT is appropriate, consider patient factors such as urgency of treatment, prognosis, and radio-resistance. In addition, consider the prior RT dose, time interval, and total spinal cord tolerance when determining the RT dose-fractionation, the authors say.

The strongly recommended options for patients with symptomatic non-spine bone metastases needing reirradiation at the same site are single-fraction RT (800 cGy in 1 fraction) or multifraction conventional palliative RT (2000 cGy in 5 fractions or 2400 cGy in 6 fractions).
 

Impact of Techniques and Dose-fractionation on Quality of Life and Toxicity

For patients with bone metastases undergoing palliative radiation, it is strongly recommended to use a shared decision-making approach to determine the dose, fractionation, and supportive measures to optimize quality of life.

“Based on published data, the ASTRO task force’s recommendations inform best clinical practices on palliative RT for symptomatic bone metastases,” the guideline panelists said.

Limitations

While the guideline provides comprehensive recommendations, the panelists underscored the importance of individualized treatment approaches. Future research is needed to address gaps in evidence, particularly regarding advanced RT techniques and reirradiation strategies.

Guideline development was funded by ASTRO, with the systematic evidence review funded by the Patient-Centered Outcomes Research Institute. The panelists disclosed relationships with AstraZeneca, Elekta, Teladoc, and others.

“Based on published data, the ASTRO task force’s recommendations inform best clinical practices on palliative RT for symptomatic bone metastases,” the guideline panelists said.

Limitations

While the guideline provides comprehensive recommendations, the panelists underscored the importance of individualized treatment approaches. Future research is needed to address gaps in evidence, particularly regarding advanced RT techniques and reirradiation strategies.

Guideline development was funded by ASTRO, with the systematic evidence review funded by the Patient-Centered Outcomes Research Institute. The panelists disclosed relationships with AstraZeneca, Elekta, Teladoc, and others.

A new clinical practice guideline by the American Society for Radiation Oncology (ASTRO) steers use of external beam radiation therapy (EBRT) for the palliation of symptomatic bone metastases, including recommendations concerning pain management and quality of life.

The guideline was needed to update previous recommendations and incorporate new high-quality evidence for the management of symptomatic bone metastases, Sara Alcorn, MD, PhD, of the University of Minnesota, Minneapolis, and colleagues wrote in Practical Radiation Oncology.

The focus was on the efficacy of EBRT in reducing pain, improving skeletal function, and enhancing quality of life, they wrote in the clinical practice guideline.

In developing their recommendations, the ASTRO task force reviewed evidence from 53 randomized controlled trials (RCTs) and 31 nonrandomized studies, and considered clinical experience.
 

Indications for Palliative Radiation

EBRT is strongly recommended for reducing pain from osseous metastasis and improving ambulatory status, sphincter function, and reducing pain in patients with spinal metastases causing compression of the spinal cord or cauda equina.

For patients with symptomatic bone metastases and an anticipated life expectancy of at least 4 weeks, EBRT is conditionally recommended to improve quality of life.

Implementation of other Treatments Alongside Palliative Radiation

Instead of RT alone, surgery with postoperative RT is conditionally recommended for patients with compression of the spinal cord or cauda equina.

Postoperative RT is strongly recommended for patients who have undergone surgery for non-spine bone metastases or spine metastases without involving spinal cord or cauda equina compression.

For patients with spinal bone metastases compressing the spinal cord or cauda equina, combining RT with dexamethasone is strongly recommended over RT alone.

Techniques, Dose-Fractionation, and Dose-Constraints for Initial Palliative Radiation

For patients with symptomatic bone metastases undergoing conventional palliative RT, strongly recommended doses are 800 cGy in 1 fraction, 2000 cGy in 5 fractions, 2400 cGy in 6 fractions, or 3000 cGy in 10 fractions.

For patients with spinal bone metastases causing compression of the spinal cord or cauda equina who are not candidates for initial surgical decompression and are treated with conventional palliative RT, strongly recommended doses are 800 cGy in 1 fraction, 1600 cGy in 2 fractions, 2000 cGy in 5 fractions, or 3000 cGy in 10 fractions.

When selecting dose-fractionation, consider patient and disease factors such as prognosis and radiosensitivity, the authors wrote.

Highly conformal planning and delivery techniques, such as intensity-modulated radiation therapy, are conditionally recommended for patients with spinal bone metastases compressing the spinal cord or cauda equina who are receiving dose-escalated palliative RT.

The strongly recommended stereotactic body radiotherapy (SBRT) doses for patients with symptomatic bone metastases are 1200 to 1600 cGy in 1 fraction for non-spine metastases and 2400 cGy in 2 fractions for spine metastases. Other established SBRT dose and fractionation regimens with similar biologically effective doses may be considered based on patient tumor characteristics, normal tissue factors, and physician experience.

For patients with symptomatic bone metastases who have an ECOG PS of 0-2, are not undergoing surgical intervention, and have no neurological symptoms, SBRT is conditionally recommended over conventional palliative RT. Other factors to consider include life expectancy, tumor radiosensitivity, and metastatic disease burden, the guideline says.
 

Techniques, Dose-Fractionation, and Dose-Constraints for Palliative Reirradiation

For patients with spinal bone metastases requiring reirradiation to the same site, the strongly recommended conventional palliative RT regimens are 800 cGy in 1 fraction, 2000 cGy in 5 fractions, 2400 cGy in 6 fractions, or 2000 cGy in 8 fractions. When determining the RT dose-fractionation, consider the prior RT dose, time interval, and total spinal cord tolerance, the guideline says.

Treatment with SBRT is conditionally recommended for patients with spinal bone metastases needing reirradiation at the same site. When determining if SBRT is appropriate, consider patient factors such as urgency of treatment, prognosis, and radio-resistance. In addition, consider the prior RT dose, time interval, and total spinal cord tolerance when determining the RT dose-fractionation, the authors say.

The strongly recommended options for patients with symptomatic non-spine bone metastases needing reirradiation at the same site are single-fraction RT (800 cGy in 1 fraction) or multifraction conventional palliative RT (2000 cGy in 5 fractions or 2400 cGy in 6 fractions).

According to the Centers for Disease Control and Prevention (CDC), over 684,000 Americans are diagnosed with an “obesity-associated” cancer each year.

The incidence of many of these cancers has been rising in recent years, particularly among younger people — a trend that sits in contrast with the overall decline in cancers with no established relationship to excess weight, such as lung and skin cancers. 

Is obesity the new smoking? Not exactly.

Tracing a direct line between excess fat and cancer is much less clear-cut than it is with tobacco. While about 42% of cancers — including common ones such as colorectal and postmenopausal breast cancers — are considered obesity-related, only about 8% of incident cancers are attributed to excess body weight. People often develop those diseases regardless of weight.

Although plenty of evidence points to excess body fat as a cancer risk factor, it’s unclear at what point excess weight has an effect. Is gaining weight later in life, for instance, better or worse for cancer risk than being overweight or obese from a young age?

There’s another glaring knowledge gap: Does losing weight at some point in adulthood change the picture? In other words, how many of those 684,000 diagnoses might have been prevented if people shed excess pounds?

When it comes to weight and cancer risk, “there’s a lot we don’t know,” said Jennifer W. Bea, PhD, associate professor, health promotion sciences, University of Arizona, Tucson.

A Consistent but Complicated Relationship

Given the growing incidence of obesity — which currently affects about 42% of US adults and 20% of children and teenagers — it’s no surprise that many studies have delved into the potential effects of excess weight on cancer rates.

Although virtually all the evidence comes from large cohort studies, leaving the cause-effect question open, certain associations keep showing up.

“What we know is that, consistently, a higher body mass index [BMI] — particularly in the obese category — leads to a higher risk of multiple cancers,” said Jeffrey A. Meyerhardt, MD, MPH, codirector, Colon and Rectal Cancer Center, Dana-Farber Cancer Institute, Boston.

In a widely cited report published in The New England Journal of Medicine in 2016, the International Agency for Research on Cancer (IARC) analyzed over 1000 epidemiologic studies on body fat and cancer. The agency pointed to over a dozen cancers, including some of the most common and deadly, linked to excess body weight.

That list includes esophageal adenocarcinoma and endometrial cancer — associated with the highest risk — along with kidney, liver, stomach (gastric cardia), pancreatic, colorectal, postmenopausal breast, gallbladder, ovarian, and thyroid cancers, plus multiple myeloma and meningioma. There’s also “limited” evidence linking excess weight to additional cancer types, including aggressive prostate cancer and certain head and neck cancers.

At the same time, Dr. Meyerhardt said, many of those same cancers are also associated with issues that lead to, or coexist with, overweight and obesity, including poor diet, lack of exercise, and metabolic conditions such as diabetes. 

It’s a complicated web, and it’s likely, Dr. Meyerhardt said, that high BMI both directly affects cancer risk and is part of a “causal pathway” of other factors that do.

Regarding direct effects, preclinical research has pointed to multiple ways in which excess body fat could contribute to cancer, said Karen M. Basen-Engquist, PhD, MPH, professor, Division of Cancer Prevention and Population Services, The University of Texas MD Anderson Cancer Center, Houston.

One broad mechanism to help explain the obesity-cancer link is chronic systemic inflammation because excess fat tissue can raise levels of substances in the body, such as tumor necrosis factor alpha and interleukin 6, which fuel inflammation. Excess fat also contributes to hyperinsulinemia — too much insulin in the blood — which can help promote the growth and spread of tumor cells. 

But the underlying reasons also appear to vary by cancer type, Dr. Basen-Engquist said. With hormonally driven cancer types, such as breast and endometrial, excess body fat may alter hormone levels in ways that spur tumor growth. Extra fat tissue may, for example, convert androgens into estrogens, which could help feed estrogen-dependent tumors.

That, Dr. Basen-Engquist noted, could be why excess weight is associated with postmenopausal, not premenopausal, breast cancer: Before menopause, body fat is a relatively minor contributor to estrogen levels but becomes more important after menopause.

How Big Is the Effect?

While more than a dozen cancers have been consistently linked to excess weight, the strength of those associations varies considerably. 

Endometrial and esophageal cancers are two that stand out. In the 2016 IARC analysis, people with severe obesity had a seven-times greater risk for endometrial cancer and 4.8-times greater risk for esophageal adenocarcinoma vs people with a normal BMI.

With other cancers, the risk increases for those with severe obesity compared with a normal BMI were far more modest: 10% for ovarian cancer, 30% for colorectal cancer, and 80% for kidney and stomach cancers, for example. For postmenopausal breast cancer, every five-unit increase in BMI was associated with a 10% relative risk increase.

A 2018 study from the American Cancer Society, which attempted to estimate the proportion of cancers in the United States attributable to modifiable risk factors — including alcohol consumption, ultraviolet rays exposure, and physical inactivity — found that smoking accounted for the highest proportion of cancer cases by a wide margin (19%), but excess weight came in second (7.8%).

Again, weight appeared to play a bigger role in certain cancers than others: An estimated 60% of endometrial cancers were linked to excess weight, as were roughly one third of esophageal, kidney, and liver cancers. At the other end of the spectrum, just over 11% of breast, 5% of colorectal, and 4% of ovarian cancers were attributable to excess weight.

Even at the lower end, those rates could make a big difference on the population level, especially for groups with higher rates of obesity.

CDC data show that obesity-related cancers are rising among women younger than 50 years, most rapidly among Hispanic women, and some less common obesity-related cancers, such as stomach, thyroid and pancreatic, are also rising among Black individuals and Hispanic Americans.

Obesity may be one reason for growing cancer disparities, said Leah Ferrucci, PhD, MPH, assistant professor, epidemiology, Yale School of Public Health, New Haven, Connecticut. But, she added, the evidence is limited because Black individuals and Hispanic Americans are understudied.

When Do Extra Pounds Matter?

When it comes to cancer risk, at what point in life does excess weight, or weight gain, matter? Is the standard weight gain in middle age, for instance, as hazardous as being overweight or obese from a young age?

Some evidence suggests there’s no “safe” time for putting on excess pounds.

A recent meta-analysis concluded that weight gain at any point after age 18 years is associated with incremental increases in the risk for postmenopausal breast cancer. A 2023 study in JAMA Network Open found a similar pattern with colorectal and other gastrointestinal cancers: People who had sustained overweight or obesity from age 20 years through middle age faced an increased risk of developing those cancers after age 55 years. 

The timing of weight gain didn’t seem to matter either. The same elevated risk held among people who were normal weight in their younger years but became overweight after age 55 years.

Those studies focused on later-onset disease. But, in recent years, experts have tracked a troubling rise in early-onset cancers — those diagnosed before age 50 years — particularly gastrointestinal cancers. 

An obvious question, Dr. Meyerhardt said, is whether the growing prevalence of obesity among young people is partly to blame.

There’s some data to support that, he said. An analysis from the Nurses’ Health Study II found that women with obesity had double the risk for early-onset colorectal cancer as those with a normal BMI. And every 5-kg increase in weight after age 18 years was associated with a 9% increase in colorectal cancer risk.

But while obesity trends probably partly explain the rise in early-onset cancers, there is likely more to the story, Dr. Meyerhardt said.

“I think all of us who see an increasing number of patients under 50 with colorectal cancer know there’s a fair number who do not fit that [high BMI] profile,” he said. “There’s a fair number over 50 who don’t either.”

Does Weight Loss Help?

With all the evidence pointing to high BMI as a cancer risk factor, a logical conclusion is that weight loss should reduce that excess risk. However, Dr. Bea said, there’s actually little data to support that, and what exists comes from observational studies.

Some research has focused on people who had substantial weight loss after bariatric surgery, with encouraging results. A study published in JAMA found that among 5053 people who underwent bariatric surgery, 2.9% developed an obesity-related cancer over 10 years compared with 4.9% in the nonsurgery group.

Most people, however, aim for less dramatic weight loss, with the help of diet and exercise or sometimes medication. Some evidence shows that a modest degree of weight loss may lower the risks for postmenopausal breast and endometrial cancers. 

A 2020 pooled analysis found, for instance, that among women aged ≥ 50 years, those who lost as little as 2.0-4.5 kg, or 4.4-10.0 pounds, and kept it off for 10 years had a lower risk for breast cancer than women whose weight remained stable. And losing more weight — 9 kg, or about 20 pounds, or more — was even better for lowering cancer risk.

But other research suggests the opposite. A recent analysis found that people who lost weight within the past 2 years through diet and exercise had a higher risk for a range of cancers compared with those who did not lose weight. Overall, though, the increased risk was quite low.

Whatever the research does, or doesn’t, show about weight and cancer risk, Dr. Basen-Engquist said, it’s important that risk factors, obesity and otherwise, aren’t “used as blame tools.”

“With obesity, behavior certainly plays into it,” she said. “But there are so many influences on our behavior that are socially determined.”

Both Dr. Basen-Engquist and Dr. Meyerhardt said it’s important for clinicians to consider the individual in front of them and for everyone to set realistic expectations. 

People with obesity should not feel they have to become thin to be healthier, and no one has to leap from being sedentary to exercising several hours a week. 

“We don’t want patients to feel that if they don’t get to a stated goal in a guideline, it’s all for naught,” Dr. Meyerhardt said.

An analysis from the Nurses’ Health Study II found that women with obesity had double the risk for early-onset colorectal cancer as those with a normal BMI. And every 5-kg increase in weight after age 18 years was associated with a 9% increase in colorectal cancer risk.

But while obesity trends probably partly explain the rise in early-onset cancers, there is likely more to the story, Dr. Meyerhardt said.

“I think all of us who see an increasing number of patients under 50 with colorectal cancer know there’s a fair number who do not fit that [high BMI] profile,” he said. “There’s a fair number over 50 who don’t either.”

Does Weight Loss Help?

With all the evidence pointing to high BMI as a cancer risk factor, a logical conclusion is that weight loss should reduce that excess risk. However, Dr. Bea said, there’s actually little data to support that, and what exists comes from observational studies.

Some research has focused on people who had substantial weight loss after bariatric surgery, with encouraging results. A study published in JAMA found that among 5053 people who underwent bariatric surgery, 2.9% developed an obesity-related cancer over 10 years compared with 4.9% in the nonsurgery group.

Most people, however, aim for less dramatic weight loss, with the help of diet and exercise or sometimes medication. Some evidence shows that a modest degree of weight loss may lower the risks for postmenopausal breast and endometrial cancers. 

A 2020 pooled analysis found, for instance, that among women aged ≥ 50 years, those who lost as little as 2.0-4.5 kg, or 4.4-10.0 pounds, and kept it off for 10 years had a lower risk for breast cancer than women whose weight remained stable. And losing more weight — 9 kg, or about 20 pounds, or more — was even better for lowering cancer risk.

But other research suggests the opposite. A recent analysis found that people who lost weight within the past 2 years through diet and exercise had a higher risk for a range of cancers compared with those who did not lose weight. Overall, though, the increased risk was quite low.

Whatever the research does, or doesn’t, show about weight and cancer risk, Dr. Basen-Engquist said, it’s important that risk factors, obesity and otherwise, aren’t “used as blame tools.”

“With obesity, behavior certainly plays into it,” she said. “But there are so many influences on our behavior that are socially determined.”

Both Dr. Basen-Engquist and Dr. Meyerhardt said it’s important for clinicians to consider the individual in front of them and for everyone to set realistic expectations. 

People with obesity should not feel they have to become thin to be healthier, and no one has to leap from being sedentary to exercising several hours a week. 

“We don’t want patients to feel that if they don’t get to a stated goal in a guideline, it’s all for naught,” Dr. Meyerhardt said.
