Weekend Workout, Regular Exercise Are Equals at Lowering GI Disease Risk
SAN DIEGO — The session started with a question that many in the audience at Digestive Disease Week (DDW) 2025 seemed to relate to: “How many of you find yourself squeezing workouts into a weekend after a hectic work week?”
Although regular exercise three or more times a week is often viewed as preferable, Shiyi Yu, MD, a resident physician in the Department of Gastroenterology at Guangdong Provincial People’s Hospital in Guangzhou, China, had good news for weekend warriors.
Both patterns reduce digestive disease almost equally.
Her study compared weekend warriors with those she called “active regulars” and sedentary folks to see how activity patterns affect digestive disease risks.
Her bottom line: “Your gut does not care about your schedule.”
The researchers analyzed wrist-based accelerometer data from 89,595 participants in the UK Biobank. To categorize participants as active or inactive, they used the World Health Organization 2020 guidelines for physical activity, which recommend at least 150-300 minutes of moderate-intensity aerobic physical activity or at least 75-150 minutes of vigorous-intensity aerobic physical activity, or an equivalent combination throughout the week. Median age of participants was 63.3 years and 48.8% were men.
They divided participants into three groups:
- About 43% were weekend warriors who met or exceeded 150 minutes of moderate to vigorous physical activity (MVPA), with 50% or more of total MVPA achieved in 1-2 days.
- About 23% were active regulars who met or exceeded 150 minutes a week but spread over more days.
- About 34% were inactive participants who were active less than 150 minutes a week.
The researchers followed the participants for a median of 7.9 years, looking for the incidence of multiple digestive diseases, identified using the International Classification of Diseases, 10th Revision, codes. These included diverticulosis, constipation, metabolic dysfunction–associated steatotic liver disease, cholelithiasis, and gastroesophageal reflux disease.
,” Yu said. At the threshold ≥ 150 minutes, for instance, hazard ratios for any digestive disease were 0.83 for weekend warriors and 0.79 for active regulars, compared with sedentary participants.
The analysis was repeated using a median threshold ≥ 230.4 minutes of MVPA a week, and the researchers found the same results.
As a validation cohort, the researchers used more than 6,000 participants from the National Institutes of Health’s All of Us Research Program with over 6 months of wrist-based accelerometer data.
A recent meta-epidemiology study found that the weekend warrior pattern offers other health benefits, including reducing the risk for cardiovascular disease mortality, mental disorders, and metabolic syndrome.
A Pleasant Surprise
The digestive disease study’s findings were “a surprise and a pleasant one,” said Aasma Shaukat, MD, MPH, AGAF, professor of medicine and a gastroenterologist at NYU Grossman School of Medicine, New York City.
“We often think if we’re not able to exercise regularly, then there’s no hope for us,” said Shaukat, who moderated the session. “But this implies that even if we have time only during the weekend to engage in physical activity, it still confers benefits in reducing our risk of any GI health disorder, as well as cardiovascular or other health disorders, compared to people inactive at baseline.”
“It gives us flexibility in terms of how we structure our exercise. Obviously, people should try to get into the habit of doing regular activity; it’s more sustainable. But a good alternative, according to this research, is that packing all of that in over the weekend seems to confer benefit. So all is not lost.”
Will this change her conversation with patients moving forward? Absolutely, Shaukat said. She generally recommends physical activity for at least 30 minutes three times a week. Now Shaukat said she can tell patients: “If that’s not possible, take that time out during the weekend for your health”.
This study was funded by grants from the National Natural Science Foundation of China and its Regional Innovation and Development Joint Foundation. Yu and Shaukat reported no disclosures.

Do GLP-1s Lower CRC Risk in Patients With Obesity and T2D?
SAN DIEGO — new research showed.
CRC risk was also lower for patients taking GLP-1s than the general population.
“Our findings show we might need to evaluate these therapies beyond their glycemic or weight loss [effects],” said first author Omar Al Ta’ani, MD, of the Allegheny Health Network, Pittsburgh.
This supports future prospective studies examining GLP-1s for CRC reduction, added Ta’ani, who presented the results at Digestive Disease Week (DDW) 2025.
Patients with type 2 diabetes and obesity are known to have a higher risk for CRC, stemming from metabolic risk factors. Whereas prior studies suggested that GLP-1s decrease the risk for CRC compared with other antidiabetic medications, studies looking at the risk for CRC associated with bariatric surgery have had more mixed results, Ta’ani said.
For the comparison, Ta’ani and colleagues conducted a retrospective analysis of the TriNetX database, identifying patients with type 2 diabetes and obesity (body mass index [BMI] > 30) enrolled in the database between 2005 and 2019.
Overall, the study included 94,098 GLP-1 users and 24,969 patients who underwent bariatric surgery. Those with a prior history of CRC were excluded.
Using propensity score matching, patients treated with GLP-1s were matched 1:1 with patients who had bariatric surgery based on wide-ranging factors including age, race, gender, demographics, diseases, medications, personal and family history, and hemoglobin A1c.
After the propensity matching, each group included 21,022 patients. About 64% in each group were women; their median age was 53 years and about 65% were White.
Overall, the results showed that patients on GLP-1s had a significantly lower CRC risk compared with those who had bariatric surgery (adjusted hazard ratio [aHR], 0.29; P < .0001). The lower risk was also observed among those with high obesity (defined as BMI > 35) compared with those who had surgery (aHR, 0.39; P < .0001).
The results were consistent across genders; however, the differences between GLP-1s and bariatric surgery were not observed in the 18- to 45-year-old age group (BMI > 30, P = .0809; BMI > 35, P = .2318).
Compared with the general population, patients on GLP-1s also had a reduced risk for CRC (aHR, 0.28; P < .0001); however, the difference was not observed between the bariatric surgery group and the general population (aHR, 1.11; P = .3).
Among patients with type 2 diabetes with CRC and a BMI > 30, the 5-year mortality rate was lower in the GLP-1 group vs the bariatric surgery group (aHR, 0.42; P < .001).
Speculating on the mechanisms of GLP-1s that could result in a greater reduction in CRC risk, Ta’ani explained that the key pathways linking type 2 diabetes, obesity, and CRC include hyperinsulinemia, chronic inflammation, and impaired immune surveillance.
Studies have shown that GLP-1s may be more effective in addressing the collective pathways, he said. They “may improve insulin resistance and lower systemic inflammation.”
Furthermore, GLP1s “inhibit tumor pathways like Wnt/beta-catenin and PI3K/Akt/mTOR signaling, which promote apoptosis and reduce tumor cell proliferation,” he added.
Bariatric Surgery Findings Questioned
Meanwhile, “bariatric surgery’s impact on CRC remains mixed,” said Ta’ani.
Commenting on the study, Vance L. Albaugh, MD, an assistant professor of metabolic surgery at the Metamor Institute, Pennington Biomedical Research Center, Baton Rouge, Louisiana, noted that prior studies, including a recent meta-analysis, suggest a potential benefit of bariatric surgery in cancer prevention.
“I think the [current study] is interesting, but it’s been pretty [well-reported] that bariatric surgery does decrease cancer incidence, so I find it questionable that this study shows the opposite of what’s in the literature,” Albaugh, an obesity medicine specialist and bariatric surgeon, said in an interview.
Ta’ani acknowledged the study’s important limitations, including that with a retrospective design, causality cannot be firmly established.
And, as noted by an audience member in the session’s Q&A, the study ended in 2019, which was before GLP-1s had taken off as anti-obesity drugs and before US Food and Drug Administration approvals for weight loss.
Participants were matched based on BMI, however, Ta’ani pointed out.
Albaugh agreed that the study ending in 2019 was a notable limitation. However, the relatively long study period — extending from 2005 to 2019 — was a strength.
“It’s nice to have a very long period to capture people who are diagnosed, because it takes a long time to develop CRC,” he said. “To evaluate effects [of more recent drug regimens], you would not be able to have the follow-up they had.”
Other study limitations included the need to adjust for ranges of obesity severity, said Albaugh. “The risk of colorectal cancer is probably much different for someone with a BMI of 60 vs a BMI of 30.”
Ultimately, a key question the study results raise is whether GLP-1 drugs have protective effects above and beyond that of weight loss, he said.
“I think that’s a very exciting question and that’s what I think the researchers’ next work should really focus on.”
Ta’ani had no disclosures to report. Albaugh reported that he had consulted for Novo Nordisk.

ctDNA Positivity in Colorectal Cancer Links to Chemotherapy Response
SAN DIEGO — the results of the BESPOKE study showed.
“These findings highlight the value of utilizing ctDNA to select which patients should receive management chemotherapy and which patients can be potentially spared chemotherapy’s physical, emotional, and financial toxicities without compromising their long-term outcomes,” said first author Kim Magee of Natera, a clinical genetic testing company in Austin, Texas.
“ctDNA is emerging as the most powerful and prognostic biomarker in colorectal cancer,” said Magee, who presented the findings at Digestive Disease Week (DDW) 2025.
In stage II CRC, as many as 80% of patients are cured by surgery alone, while only about 5% benefit from chemotherapy. In stage III CRC, about half of patients are cured by surgery alone, while only 20% benefit from chemotherapy, and 30% recur despite chemotherapy, Magee explained.
The inability to pinpoint which patients will most benefit from chemotherapy means “we know we are needlessly treating [many] of these patients,” she said.
ctDNA Offers Insights Into Tumor’s Real-Time Status
Just as cells release fragments (cell-free DNA) into the blood as they regenerate, tumor cells also release fragments — ctDNA — which can represent a biomarker of a cancer’s current state, Magee explained.
Because the DNA fragments have a half-life of only about 2 hours, they represent a key snapshot in real time, “as opposed to imaging, which can take several weeks or months to show changes,” she said.
To determine the effects of ctDNA testing on treatment decisions and asymptomatic recurrence rates, Magee and colleagues analyzed data from the multicenter, prospective study, which used the Signatera (Natera) residual disease test.
The study included 1794 patients with resected stage II-III CRC who were treated with the standard of care between May 2020 and March 2023 who had complete clinical and laboratory data available.
ctDNA was collected 2-6 weeks post surgery and at surveillance months 2, 4, 6, and every 3 months through month 24.
Among the 1166 patients included in a final analysis, 694 (59.5%) patients received adjunctive chemotherapy, and 472 (40.5%) received no chemotherapy.
Among those with stage II CRC, a postoperative MRD positivity rate was 7.54%, while the rate in those with stage III disease was 28.35%.
Overall, 16.1% of patients had a recurrence by the trial end at 24 months.
The results showed that among patients who tested negative for ctDNA, the disease-free survival estimates were highly favorable, at 91.8% for stage II and 87.4% for stage III CRC.
Comparatively, for those who were ctDNA-positive, disease-free survival rates were just 45.9% and 35.5%, respectively, regardless of whether those patients received adjunctive chemotherapy.
At the study’s first ctDNA surveillance timepoint, patients who were ctDNA-positive with stage II and III CRC combined had substantially worse disease-free survival than patients who were ctDNA-negative (HR, 26.4; P < .0001).
Impact of Chemotherapy
Patients who were found to be MRD-positive on ctDNA testing and treated with chemotherapy had a 40.3% 2-year disease-free survival rate compared with just 24.7% among MRD-positive patients who did not receive chemotherapy.
Meanwhile, those who were MRD-negative and treated with chemotherapy had a substantially higher 2-year disease-free survival rate of 89.7% — nearly identical to the 89.5% observed in the no-chemotherapy group.
The findings underscored that “the adjuvant chemotherapy benefits were only observed among those who were ctDNA-positive,” Magee said.
“ctDNA can guide postsurgical treatment decisions by identifying which patients are most likely to benefit from chemotherapy, and in the surveillance setting, ctDNA can predict recurrence — usually ahead of scans,” she added. “This opens the opportunity to intervene and give those patients a second chance at cure.”
On the heels of major recent advances including CT, MRI, and PET-CT, “we believe that ctDNA represents the next major pivotal advancement in monitoring and eventually better understanding cancer diagnostics,” Magee said.
Commenting on the study, William M. Grady, MD, AGAF, medical director of the Fred Hutchinson Cancer Center Gastrointestinal Cancer Prevention Clinic, Seattle, said the BESPOKE trial represents a “well-done” study, adding to research underscoring that “MRD testing is a more accurate prognostic assay than the current standards of CT scan and CEA [carcinoembryonic antigen, a tumor marker] testing.”
However, “a limitation is that this is 2 years of follow-up, [while] 5-year follow-up data would be ideal,” he said in an interview, noting, importantly, that “a small number of patients who have no evidence of disease (NED) at 2 years develop recurrence by 5 years.”
Furthermore, more research demonstrating the outcomes of MRD detection is needed, Grady added.
“A caveat is that studies are still needed showing that if you change your care of patients based on the MRD result, that you improve outcomes,” he said. “These studies are being planned and initiated at this time, from my understanding.”
Oncologists treating patients with CRC are commonly performing MRD assessment with ctDNA assays; however, Grady noted that the practice is still not the standard of care.
Regarding the suggestion of ctDNA representing the next major, pivotal step in cancer monitoring, Grady responded that “I think this is aspirational, and further studies are needed to make this claim.”
However, “it does look like it has the promise to turn out to be true.”

SAN DIEGO — the results of the BESPOKE study showed.
“These findings highlight the value of utilizing ctDNA to select which patients should receive management chemotherapy and which patients can be potentially spared chemotherapy’s physical, emotional, and financial toxicities without compromising their long-term outcomes,” said first author Kim Magee of Natera, a clinical genetic testing company in Austin, Texas.
“ctDNA is emerging as the most powerful and prognostic biomarker in colorectal cancer,” said Magee, who presented the findings at Digestive Disease Week (DDW) 2025.
In stage II CRC, as many as 80% of patients are cured by surgery alone, while only about 5% benefit from chemotherapy. In stage III CRC, about half of patients are cured by surgery alone, while only 20% benefit from chemotherapy, and 30% recur despite chemotherapy, Magee explained.
The inability to pinpoint which patients will most benefit from chemotherapy means “we know we are needlessly treating [many] of these patients,” she said.
ctDNA Offers Insights Into Tumor’s Real-Time Status
Just as cells release fragments (cell-free DNA) into the blood as they regenerate, tumor cells also release fragments — ctDNA — which can represent a biomarker of a cancer’s current state, Magee explained.
Because the DNA fragments have a half-life of only about 2 hours, they represent a key snapshot in real time, “as opposed to imaging, which can take several weeks or months to show changes,” she said.
To determine the effects of ctDNA testing on treatment decisions and asymptomatic recurrence rates, Magee and colleagues analyzed data from the multicenter, prospective study, which used the Signatera (Natera) residual disease test.
The study included 1794 patients with resected stage II-III CRC who were treated with the standard of care between May 2020 and March 2023 who had complete clinical and laboratory data available.
ctDNA was collected 2-6 weeks post surgery and at surveillance months 2, 4, 6, and every 3 months through month 24.
Among the 1166 patients included in a final analysis, 694 (59.5%) patients received adjunctive chemotherapy, and 472 (40.5%) received no chemotherapy.
Among those with stage II CRC, a postoperative MRD positivity rate was 7.54%, while the rate in those with stage III disease was 28.35%.
Overall, 16.1% of patients had a recurrence by the trial end at 24 months.
The results showed that among patients who tested negative for ctDNA, the disease-free survival estimates were highly favorable, at 91.8% for stage II and 87.4% for stage III CRC.
Comparatively, for those who were ctDNA-positive, disease-free survival rates were just 45.9% and 35.5%, respectively, regardless of whether those patients received adjunctive chemotherapy.
At the study’s first ctDNA surveillance timepoint, patients who were ctDNA-positive with stage II and III CRC combined had substantially worse disease-free survival than patients who were ctDNA-negative (HR, 26.4; P < .0001).
Impact of Chemotherapy
Patients who were found to be MRD-positive on ctDNA testing and treated with chemotherapy had a 40.3% 2-year disease-free survival rate compared with just 24.7% among MRD-positive patients who did not receive chemotherapy.
Meanwhile, those who were MRD-negative and treated with chemotherapy had a substantially higher 2-year disease-free survival rate of 89.7% — nearly identical to the 89.5% observed in the no-chemotherapy group.
The findings underscored that “the adjuvant chemotherapy benefits were only observed among those who were ctDNA-positive,” Magee said.
“ctDNA can guide postsurgical treatment decisions by identifying which patients are most likely to benefit from chemotherapy, and in the surveillance setting, ctDNA can predict recurrence — usually ahead of scans,” she added. “This opens the opportunity to intervene and give those patients a second chance at cure.”
On the heels of major recent advances including CT, MRI, and PET-CT, “we believe that ctDNA represents the next major pivotal advancement in monitoring and eventually better understanding cancer diagnostics,” Magee said.
Commenting on the study, William M. Grady, MD, AGAF, medical director of the Fred Hutchinson Cancer Center Gastrointestinal Cancer Prevention Clinic, Seattle, said the BESPOKE trial represents a “well-done” study, adding to research underscoring that “MRD testing is a more accurate prognostic assay than the current standards of CT scan and CEA [carcinoembryonic antigen, a tumor marker] testing.”
However, “a limitation is that this is 2 years of follow-up, [while] 5-year follow-up data would be ideal,” he said in an interview, noting, importantly, that “a small number of patients who have no evidence of disease (NED) at 2 years develop recurrence by 5 years.”
Furthermore, more research demonstrating the outcomes of MRD detection is needed, Grady added.
“A caveat is that studies are still needed showing that if you change your care of patients based on the MRD result, that you improve outcomes,” he said. “These studies are being planned and initiated at this time, from my understanding.”

SGLT2 Inhibitors Reduce Portal Hypertension From Cirrhosis
SAN DIEGO —
, new research shows.“Our study found that SGLT2 inhibitors were associated with fewer portal hypertension complications and lower mortality, suggesting they may be a valuable addition to cirrhosis management,” first author Abhinav K. Rao, MD, of the Medical University of South Carolina, Charleston, South Carolina, told GI & Hepatology News.
The findings were presented at Digestive Disease Week (DDW) 2025.
Portal hypertension, a potentially life-threatening complication of cirrhosis, can be a key driver of additional complications including ascites and gastro-esophageal varices in cirrhosis.
Current treatments such as beta-blockers can prevent some complications, however, more effective therapies are needed.
SGLT2 inhibitors are often used in the treatment of cardiovascular disease as well as metabolic dysfunction–associated steatohepatitis (MASH)–mediated liver disease; research is lacking regarding their effects in portal hypertension in the broader population of people with cirrhosis.
“The therapeutic efficacy of SGLT2 inhibitors might be related to their ability to improve vascular function, making them attractive in portal hypertension,” Rao explained.
To investigate, Rao and colleagues evaluated data on 637,079 patients with cirrhosis in the TriNetX database, which includes patients in the United States from 66 healthcare organizations.
Patients were divided into three subgroups, including those with MASH, alcohol-associated, and other etiologies of cirrhosis.
Using robust 1:1 propensity score matching, patients in each subgroup were stratified as either having or not having been treated with SGLT2 inhibitors, limited to those who initiated the drugs within 1 year of their cirrhosis diagnosis to prevent immortal time bias. Patients were matched on other characteristics.
For the primary outcome of all-cause mortality, with an overall median follow-up of 2 years, patients prescribed SGLT2 inhibitors in the MASH cirrhosis (n = 47,385), alcohol-associated cirrhosis (n = 107,844), and other etiologies of cirrhosis (n = 59,499) groups all had a significantly lower risk for all-cause mortality than those not prescribed SGLT2 inhibitors (P < .05 for all).
SGLT2 Inhibitors in MASH Cirrhosis
Specifically looking at the MASH cirrhosis group, Rao described outcomes of the two groups of 3026 patients each who were and were not treated with SGLT2 inhibitors.
The patients had similar rates of esophageal varices (25% in the SGLT2 group and 22% in the no SGLT2 group), ascites (19% in each group), and a similar rate of 19% had hepatic encephalopathy (HE).
About 57% of patients in each treatment group used beta-blockers and 33% used glucagon-like peptide 1 (GLP-1) receptor agonists. Those with a history of liver transplantation, hemodialysis, or transjugular intrahepatic portosystemic shunt placement were excluded.
The secondary outcome results in those patients showed that treatment with SGLT2 inhibitors was associated with significantly reduced risks of developing portal hypertension complications including ascites, HE, spontaneous bacterial peritonitis (SBP), and hepatorenal syndrome (P < .05 for all).
Esophageal variceal bleeding was also reduced with SGLT-2 inhibitors; however the difference was not statistically significant.
Effects Diminished With Beta-Blocker Treatment
In a secondary analysis of patients in the MASH cirrhosis group treated with one type of a nonselective beta-blockers (n = 509) and another nonselective beta-blockers (n = 2561), the beneficial effects of SGLT2 inhibitors on portal hypertension, with the exception of HE and SBP, were found to be somewhat diminished, likely because patients were already benefitting from the beta-blockers, Rao noted.
Other Groups
In outcomes of the non–MASH-related cirrhosis groups, patients prescribed SGLT2 inhibitors also had a reduced risk for specific, as well as any portal hypertension complications (P < .05), Rao noted.
Overall, the findings add to previous studies on SGLT2 inhibitors in MASH and expand on the possible benefits, he said.
“Our findings validate these [previous] results and suggest potential benefits across for patients with other types of liver disease and raise the possibility of a beneficial effect in portal hypertension,” he said.
“Given the marked reduction in portal hypertension complications after SGLT2 inhibitor initiation, the associated survival benefit may not be surprising,” he noted.
“However, we were intrigued by the consistent reduction in portal hypertension complications across all cirrhosis types, especially since SGLT-2 inhibitors are most commonly used in patients with diabetes who have MASH-mediated liver disease.”
‘Real World Glimpse’ at SGLT2 Inhibitors; Limitations Need Noting
Commenting on the study, Rotonya M. Carr, MD, Division Head of Gastroenterology at the University of Washington, Seattle, said the study sheds important light on an issue previously addressed only in smaller cohorts.
“To date, there have only been a few small prospective, retrospective, and case series studies investigating SGTL2 inhibitors in patients with cirrhosis,” she told GI & Hepatology Newsv.
“This retrospective study is a real-world glimpse at how patients with cirrhosis may fare on these drugs — very exciting data.”
Carr cautioned, however, that, in addition to the retrospective study design, limitations included that the study doesn’t provide details on the duration of therapy, preventing an understanding of whether the results represent chronic, sustained use of SGLT2 inhibitors.
“[Therefore], we cannot interpret these results to mean that chronic, sustained use of SGTL2 inh is beneficial, or does not cause harm, in patients with cirrhosis.”
“While these data are provocative, more work needs to be done before we understand the full safety and efficacy of SGTL2 inhibitors for patients with cirrhosis,” Carr added.
“However, these data are very encouraging, and I am optimistic that we will indeed see both SGTL2 inhibitors and GLP-1s among the group of medications we use in the future for the primary management of patients with liver disease.”
The authors had no disclosures to report. Carr’s disclosures included relationships with Intercept and Novo Nordisk and research funding from Merck.

AI-Enhanced Digital Collaborative Care Improves IBS Symptoms
SAN DIEGO —
seen at Cleveland Clinic, Cleveland, Ohio, an observational study found.Symptom tracking at 4-week intervals showed that “almost everybody got better” regardless of IBS subtype, with relief starting in the first 4 weeks, Stephen Lupe, PsyD, gastrointestinal psychologist and director of Behavioral Medicine, Department of Gastroenterology, Hepatology, and Nutrition at Cleveland Clinic, Cleveland, said in an interview with GI & Hepatology News.
The findings were presented at Digestive Disease Week (DDW) 2025.
Digital Boost to Collaborative Care Model
The combination of dietary interventions and brain-gut behavioral therapy has demonstrated excellent outcomes for patients with IBS, but patients struggle to access these needed services, Lupe noted. A medical home collaborative care model in which patients get care from a multidisciplinary team has been shown to be a good way to successfully deliver this combination of care.
“When you do collaborative in-person care, people get better quicker,” Lupe said.
However, scaling access to this model remains a challenge. For their study, Cleveland Clinic researchers added an AI-enhanced digital platform, Ayble Health, to the in-person collaborative care model to expand access to disease-management services and evaluated whether it improved clinical outcomes for study’s 171 participants, who were recruited via social media advertisements.
Here’s how the platform works. Once a patient enrolls in Ayble Health, a personalized care plan is recommended based on a virtual visit, screening questionnaire, and baseline survey.
The platform includes brain-gut programs, including guided audio content on mindfulness, hypnosis, meditation, cognitive behavioral therapy, and breathing techniques; personalized nutrition support to find and remove trigger foods, a food barcode scanner, and a comprehensive groceries database; and AI-powered wellness tools to help manage and track symptoms. Lupe worked with Ayble Health to develop the platform’s behavioral health content and care pathways.
Patients may choose to follow any combination of three care pathways: A care team overseen by gastro-psychologists, dietitians, and gastroenterologists; a holistic nutrition program including a personalized elimination diet; and a brain-gut behavioral therapy program with gut-directed hypnosis, cognitive behavioral therapy, and acceptance and commitment therapy. They go at their own pace, can connect with Ayble Health’s virtual care team to help with education and goal setting, and continue to consult their Cleveland Clinic providers as needed for evaluation and treatment.
“The care team is still there. We’ve just augmented it to make sure that as many people as possible get behavioral skills training and dietary support, with monitoring between visits — instead of the traditional, ‘I’ll see you in 6 months approach,” Lupe explained.
IBS Symptom Scores Improve
Of the study’s 171 patients, 20 had IBS-diarrhea, 23 had IBS-constipation, 32 had IBS-mixed, and 8 had IBS-unspecified. The remaining 88 patients reported IBS without indication of subtype.
At intake, all patients had active IBS symptoms, with scores ≥ 75 on the IBS symptom severity scale (IBS-SSS). Most patients enrolled in more than one care pathway, and 95% of participants completed at least 4 weeks on their chosen pathways.
Overall, patients saw an average 140-point decrease in IBS-SSS from intake through follow-up lasting up to 42 weeks. A drop in IBS-SSS score ≥ 50 points was considered a clinically meaningful change.
Symptom improvements occurred as early as week 4, were sustained and were uniform across IBS subtypes, suggesting that the AI-enhanced digital collaborative care model has wide utility in patients with IBS, Lupe said.
Patients with the most severe IBS symptoms showed the greatest improvement, but even 50% of those with mild symptoms had clinically meaningful changes in IBS-SSS.
Improvement in IBS symptoms was seen across all care pathways, but the combination of multiple pathways improved outcomes better than a single care pathway alone. The combination of nutrition and brain-gut behavioral therapy demonstrated the greatest reduction in IBS-SSS scores and proportion of patients achieving clinically meaningful results (95%).
The digital comprehensive car model for IBS is now “up and running” at Cleveland Clinic, and the team plans to proactively reach out to patients with gastrointestinal disorders recently seen at their center to alert them to the availability of this tool, Lupe said.
A randomized controlled trial is planned to further validate these observational findings, he added.
‘Wave of the Future’
The digital collaborative care model is “innovative, and I think is the wave of the future,” Kyle Staller, MD, MPH, gastroenterologist and director of the Gastrointestinal Motility Laboratory at Massachusetts General Hospital, Boston, who wasn’t involved in the study, told GI & Hepatology News.
“These digital platforms bundle nondrug options, such as cognitive-behavioral therapy, dietary therapy, hypnotherapy, so patients can choose what suits them, rather than the gastroenterologist hunting down each individual resource, which requires a lot of work,” Staller said.
The study “provides real-world evidence that a deliberative, digital, collaborative care model that houses various types of nondrug IBS treatment under one roof can provide meaningful benefit to patients,” Staller told GI & Hepatology News.
Importantly, he said, “patients chose which option they wanted. At the end of the day, the way that we should be thinking about IBS care is really making sure that we engage the patient with treatment choices,” Staller said.
This study had no specific funding. Three authors had relationships with Ayble Health. Lupe is a scientific advisor for Boomerang Health and paid lecturer for Takeda Pharmaceuticals. Staller disclosed having relationships with Mahana Therapeutics, Ardelyx Inc, Gemelli Biotech, Salix Pharmaceuticals, and Takeda Pharmaceuticals.

SAN DIEGO —
seen at Cleveland Clinic, Cleveland, Ohio, an observational study found.Symptom tracking at 4-week intervals showed that “almost everybody got better” regardless of IBS subtype, with relief starting in the first 4 weeks, Stephen Lupe, PsyD, gastrointestinal psychologist and director of Behavioral Medicine, Department of Gastroenterology, Hepatology, and Nutrition at Cleveland Clinic, Cleveland, said in an interview with GI & Hepatology News.
The findings were presented at Digestive Disease Week (DDW) 2025.
Digital Boost to Collaborative Care Model
The combination of dietary interventions and brain-gut behavioral therapy has demonstrated excellent outcomes for patients with IBS, but patients struggle to access these needed services, Lupe noted. A medical home collaborative care model in which patients get care from a multidisciplinary team has been shown to be a good way to successfully deliver this combination of care.
“When you do collaborative in-person care, people get better quicker,” Lupe said.
However, scaling access to this model remains a challenge. For their study, Cleveland Clinic researchers added an AI-enhanced digital platform, Ayble Health, to the in-person collaborative care model to expand access to disease-management services and evaluated whether it improved clinical outcomes for study’s 171 participants, who were recruited via social media advertisements.
Here’s how the platform works. Once a patient enrolls in Ayble Health, a personalized care plan is recommended based on a virtual visit, screening questionnaire, and baseline survey.
The platform includes brain-gut programs, including guided audio content on mindfulness, hypnosis, meditation, cognitive behavioral therapy, and breathing techniques; personalized nutrition support to find and remove trigger foods, a food barcode scanner, and a comprehensive groceries database; and AI-powered wellness tools to help manage and track symptoms. Lupe worked with Ayble Health to develop the platform’s behavioral health content and care pathways.
Patients may choose to follow any combination of three care pathways: A care team overseen by gastro-psychologists, dietitians, and gastroenterologists; a holistic nutrition program including a personalized elimination diet; and a brain-gut behavioral therapy program with gut-directed hypnosis, cognitive behavioral therapy, and acceptance and commitment therapy. They go at their own pace, can connect with Ayble Health’s virtual care team to help with education and goal setting, and continue to consult their Cleveland Clinic providers as needed for evaluation and treatment.
“The care team is still there. We’ve just augmented it to make sure that as many people as possible get behavioral skills training and dietary support, with monitoring between visits — instead of the traditional, ‘I’ll see you in 6 months approach,” Lupe explained.
IBS Symptom Scores Improve
Of the study’s 171 patients, 20 had IBS-diarrhea, 23 had IBS-constipation, 32 had IBS-mixed, and 8 had IBS-unspecified. The remaining 88 patients reported IBS without indication of subtype.
At intake, all patients had active IBS symptoms, with scores ≥ 75 on the IBS symptom severity scale (IBS-SSS). Most patients enrolled in more than one care pathway, and 95% of participants completed at least 4 weeks on their chosen pathways.
Overall, patients saw an average 140-point decrease in IBS-SSS from intake through follow-up lasting up to 42 weeks. A drop in IBS-SSS score ≥ 50 points was considered a clinically meaningful change.
Symptom improvements occurred as early as week 4, were sustained and were uniform across IBS subtypes, suggesting that the AI-enhanced digital collaborative care model has wide utility in patients with IBS, Lupe said.
Patients with the most severe IBS symptoms showed the greatest improvement, but even 50% of those with mild symptoms had clinically meaningful changes in IBS-SSS.
Improvement in IBS symptoms was seen across all care pathways, but the combination of multiple pathways improved outcomes better than a single care pathway alone. The combination of nutrition and brain-gut behavioral therapy demonstrated the greatest reduction in IBS-SSS scores and proportion of patients achieving clinically meaningful results (95%).
The digital comprehensive car model for IBS is now “up and running” at Cleveland Clinic, and the team plans to proactively reach out to patients with gastrointestinal disorders recently seen at their center to alert them to the availability of this tool, Lupe said.
A randomized controlled trial is planned to further validate these observational findings, he added.

Study Investigates Non-Hodgkin Lymphoma in Air Force Missileers
Individuals working near intercontinental ballistic missiles (ICBMs), may be at higher risk of developing non-Hodgkin lymphoma (NHL) according to a preprint analysis conducted on missileers at Malmstrom Air Force Base in Montana. The study, which has not undergone peer review, found higher rates of NHL diagnosis at younger ages compared with the general population. The study also found a statistically significant increase in NHL diagnoses among older missileers, with such rates surpassing expected benchmarks.
The findings build on anecdotal and evidentiary data gathered in the last 50-plus years, including from the Torchlight Initiative, established in 2023 to collect self-reported cancer diagnoses and related fatalities from personnel and family members associated with the ICBM community.
The report shows patterns that “warranted a detailed statistical analysis,” leading to a granular examination of the registry and categorization of the data by cancer type, geographical location, and specific demographics. This narrowed the focus to 18 missileers who served at Malmstrom and were diagnosed with NHL.
In 2001, the Air Force Institute for Operational Health did a site evaluation and sampled for potential chemical and biological contaminants at Malmstrom following various reports of cancers from missileers, including 2 who died after being diagnosed with NHL. In a 2005 review, the Air Force said, “there is not sufficient evidence to consider the possibility of a cancer clustering to justify further investigation.”
In 2022, Lt. Col. Daniel Sebeck, a vice commander of Space Delta 8 in Colorado who served at Malmstrom and a close friend and fellow missileer were diagnosed with NHL. Sebeck discovered 36 cancer cases among missileers who had been stationed at Malmstrom. Ten developed NHL, 2 developed Hodgkin lymphoma, and 24 developed another form of cancer. The Air Force has acknowledged the concerns.
In 2023, US Air Force School of Aerospace Medicine (USAFSAM) approved the Missile Community Cancer Study (MCCS) to assess “specific cancer concerns raised by missile community members across related career fields and also examines the possibility of clusters of non-Hodgkin’s lymphoma at intercontinental ballistic missile bases.” The study compares 14 common cancers in the general population with that of missile-related career fields. The USAFSAM is reviewing records from former and current Missile Community members on active duty from 1976-2010, as well as state and national cancer data from multiple registries.
Early results from the MCCS suggested elevated rates of some cancers—mainly breast and prostate cancer—among missileers, maintainers, and other ICMB-related job positions, which aligns with other national cancer data.
At a June 2024 AFGSC town hall, officials announced that missileers would now have their information submitted to the Defense Occupational and Environmental Health Readiness System (DOEHRS), a Pentagon database for reporting occupational and exposure hazards.
"This info from DOEHRS flows into the recently developed Individual Longitudinal Exposure Record, a system that compiles occupational and environmental health data throughout a person's career," Lt. Col. John Severns, a spokesperson for Air Force Global Strike Command, said. DOEHRS, which has tracked Air Force records since 2010, allows US Department of Defense and US Department of Veterans Affairs clinical staff to access the information.
MCCS considers potential PCB exposures an occupational hazard. The Air Force says researchers are working with the System Program Offices and leadership to determine the timeframe of PCB removal from bases.
The lack of incontrovertible evidence connecting workplace toxins to NHL has often stymied patients and their family members from receiving appropriate benefits. An “informal talk” in April led by Rep. Mark Takano (D-CA) and Sen. Richard Blumenthal (D-CT) focused on exposures to hazardous materials at US military bases. Participants included various advocacy groups like the Torchlight Initiative, the Invisible Enemy, and Burn Pits 360.
More than a dozen veterans spoke about serving at military bases where they were exposed to a variety of harmful substances, and issues they faced in receiving coverage. David Crete, a veteran and chairman of The Invisible Enemy, said, “I am asking Congress to please allow us to get the benefits every other veteran earned. We are not asking to be special but to be treated equal.”
Rep. Takano called for greater focus on toxic exposures at US military bases: “We must push back against the idea that service members are only in harm’s way in war zones.”

Exercise Can Help Protect Against Cancer Fatigue, Depression
Lingering fatigue and depression are more common among women than men cancer survivors and often lead to a decrease in recreational physical activities in all patients, new data showed.
However, moderate physical activity was linked to an almost 50% lower risk for cancer-related fatigue, and both moderate and vigorous physical activity were associated with a two- to fivefold reduced risk for depression among cancer survivors, according to the analysis presented at the American Association for Cancer Research (AACR) Annual Meeting 2025.
The findings “highlight the importance of providing special attention and tailored interventions such as exercise programs, support groups, and mind-body behavioral techniques for vulnerable groups to help effectively manage fatigue and improve participation in recreational activities as they are an essential aspect of quality of life,” Simo Du, MD, a resident at NYC Health + Hospitals and Jacobi Medical Center/Albert Einstein College of Medicine, New York City, said in a news release.
Du noted that, during her residency, cancer-related fatigue was a common complaint among patients, affecting “not just their daily activities but also their overall quality of life and mental health, making tasks like climbing stairs, doing groceries, or laundry overwhelming.”
Cancer-related fatigue affects more than 80% of patients who receive chemotherapy or radiation therapy, while depression affects around 25% of patients. Unlike typical fatigue, cancer-related fatigue can linger for weeks, months, or even years after treatment, Du explained.
Despite its high prevalence, cancer-related fatigue remains “overlooked and undertreated,” she noted during a conference press briefing. In addition, cancer-related fatigue can affect men and women differently.
To investigate further, Du and her colleagues analyzed National Health and Nutrition Examination Survey (NHANES) data from 1552 cancer survivors (736 men and 816 women).
After adjusting for age, race, socioeconomic status, and comorbidities, women cancer survivors were more likely to experience fatigue (odds ratio [OR], 1.54; P < .017) and depression (OR, 1.32; P = .341) related to their cancer compared with men cancer survivors.
Du said there are likely multiple reasons behind the sex differences observed.
Women may, for instance, be more likely to experience side effects from chemotherapy, radiation, and long-term use of endocrine treatments because of slower drug clearance, which can lead to higher concentrations and a stronger immune response that may heighten inflammatory side effects.
In multivariate logistic regression analysis, cancer-related fatigue (OR, 1.93; P = .002) and depression (OR, 2.28; P = .011) were both strongly associated with reduced moderate recreational activities, such as brisk walking, biking, golfing, and light yard work.
The data also showed a protective role for physical activity. For patients who engaged in moderate physical activity, their risk for cancer-related fatigue (OR, 0.52; P = .002) and depression (OR, 0.41; P = .006) was significantly reduced, Du reported.
For depression (but not cancer-related fatigue), “the higher the intensity of physical activity, the higher the protective effects, with almost 4-5 times the reduction of the depression,” Du noted.
Although the NHANES uses standardized protocols designed to minimize biases, Du said a limitation of the current study is the use of self-reported data and the fact that women could potentially overreport fatigue symptoms and men could potentially underreport symptoms of depression.
Looking ahead, Du and her colleagues are planning studies to assess the effectiveness of tailored interventions on cancer-related fatigue and explore the connection between cancer-related fatigue and different mechanisms, such as inflammatory markers, to see if gender modifies the association.
Commenting on the study for this news organization, Jennifer Ligibel, MD, a senior physician at the Dana-Farber Cancer Institute in Boston, said that, because the dataset is cross-sectional, it is unclear whether people who were more tired weren’t exercising or if people who weren’t exercising were more tired.
However, Ligibel explained, a huge body of literature has demonstrated that exercise is “the most efficient remedy for fatigue,” and it likely helps with depression too.
In fact, in a recent survey of patients with cancer conducted by the American Society for Clinical Oncology, slightly more than half of patients reported that their oncologist talked about exercise and diet during clinic visits, Ligibel said. Provider recommendations for exercise and diet were associated with positive changes in these behaviors.
“Roughly half of oncologists now give exercise advice; that figure is a lot more than it was a few years ago, but it’s still not universal,” Ligibel said.
The study had no specific funding. Du and Ligibel had no disclosures.

Cancer-related fatigue affects more than 80% of patients who receive chemotherapy or radiation therapy, while depression affects around 25% of patients. Unlike typical fatigue, cancer-related fatigue can linger for weeks, months, or even years after treatment, Du explained.
Despite its high prevalence, cancer-related fatigue remains “overlooked and undertreated,” she noted during a conference press briefing. In addition, cancer-related fatigue can affect men and women differently.
To investigate further, Du and her colleagues analyzed National Health and Nutrition Examination Survey (NHANES) data from 1552 cancer survivors (736 men and 816 women).
After adjusting for age, race, socioeconomic status, and comorbidities, women cancer survivors were more likely to experience fatigue (odds ratio [OR], 1.54; P < .017) and depression (OR, 1.32; P = .341) related to their cancer compared with men cancer survivors.
Du said there are likely multiple reasons behind the sex differences observed.
Women may, for instance, be more likely to experience side effects from chemotherapy, radiation, and long-term use of endocrine treatments because of slower drug clearance, which can lead to higher concentrations and a stronger immune response that may heighten inflammatory side effects.
In multivariate logistic regression analysis, cancer-related fatigue (OR, 1.93; P = .002) and depression (OR, 2.28; P = .011) were both strongly associated with reduced moderate recreational activities, such as brisk walking, biking, golfing, and light yard work.
The data also showed a protective role for physical activity. For patients who engaged in moderate physical activity, their risk for cancer-related fatigue (OR, 0.52; P = .002) and depression (OR, 0.41; P = .006) was significantly reduced, Du reported.
For depression (but not cancer-related fatigue), “the higher the intensity of physical activity, the higher the protective effects, with almost 4-5 times the reduction of the depression,” Du noted.
Although the NHANES uses standardized protocols designed to minimize biases, Du said a limitation of the current study is the use of self-reported data and the fact that women could potentially overreport fatigue symptoms and men could potentially underreport symptoms of depression.
Looking ahead, Du and her colleagues are planning studies to assess the effectiveness of tailored interventions on cancer-related fatigue and explore the connection between cancer-related fatigue and different mechanisms, such as inflammatory markers, to see if gender modifies the association.
Commenting on the study for this news organization, Jennifer Ligibel, MD, a senior physician at the Dana-Farber Cancer Institute in Boston, said that, because the dataset is cross-sectional, it is unclear whether people who were more tired weren’t exercising or if people who weren’t exercising were more tired.
However, Ligibel explained, a huge body of literature has demonstrated that exercise is “the most efficient remedy for fatigue,” and it likely helps with depression too.
In fact, in a recent survey of patients with cancer conducted by the American Society for Clinical Oncology, slightly more than half of patients reported that their oncologist talked about exercise and diet during clinic visits, Ligibel said. Provider recommendations for exercise and diet were associated with positive changes in these behaviors.
“Roughly half of oncologists now give exercise advice; that figure is a lot more than it was a few years ago, but it’s still not universal,” Ligibel said.
The study had no specific funding. Du and Ligibel had no disclosures.

Single Antiplatelet After TAVR Lowers Risk
Patients who received a single antiplatelet drug therapy — usually aspirin — after transcatheter aortic valve replacement (TAVR) had about half the risk of dying in the subsequent 6 months compared with patients who received dual antiplatelet drug therapy. The findings were similar in men and women and in patients with and without coronary artery disease.
“This is one of the first demonstrations in real-world data that single antiplatelet therapy is not only associated with a lower risk of bleeding but also lower mortality,” said lead author Francesco Pelliccia, MD, PhD, a cardiologist at Sapienza University in Rome, Italy. Mortality rates for those who received dual antiplatelet therapy increased steadily during the 6 months after the procedure, he reported at the Society for Cardiovascular Angiography and Interventions (SCAI) 2025 Scientific Sessions in Washington, DC.
Ischemic and major bleeding events were dramatically reduced in those receiving a single drug, according to a real-world study of 5514 patients undergoing TAVR at 20 centers. The centers participate in the Transfusion Requirements in Transcatheter Aortic Valve Implantation (TRITAVI) registry.
In the 6 months after the procedure, 2.4% of the 3197 patients who received a single antiplatelet drug died of any cause, as did 5.4% of 2317 patients who received two antiplatelet drugs (hazard ratio [HR], 1.65). Dual therapy was associated with a higher risk for death in both men (HR, 2.08) and women (HR, 1.53). Risk for death was also higher in patients with coronary artery disease (HR, 1.83) and without coronary artery disease (HR, 1.52). All results were statistically significant.
Balancing Risks and Benefits
The popularity of TAVR, which was introduced in 2002, has grown to the point that, in 2019, it surpassed the use of surgical aortic valve replacement. But the procedure is associated with an increased risk for both thrombosis and bleeding. Antiplatelet therapy with aspirin and clopidogrel helps prevent thrombosis but can increase the risk of bleeding. This has led to a debate about the best balance for antiplatelet therapy after TAVR with either single therapy — usually with aspirin — or dual therapy with both aspirin and clopidogrel.
A series of studies have addressed this problem. Dual therapy did not show any benefits over single therapy in terms of major adverse cardiac and cerebrovascular events in a 2011 small randomized study. A 2014 small randomized study also showed no benefit for morbidity or mortality from dual therapy. A larger 2017 randomized trial showed that single therapy reduced the risk for major or life-threatening events but did not increase the risk for myocardial infarction or stroke.
Bleeding and bleeding plus thromboembolic events were significantly lower with aspirin than with aspirin plus clopidogrel after a year’s follow-up in the 2020 POPular TAVI trial. Findings from three of these trials were pooled in a 2018 meta-analysis, which showed that dual therapy increased the risk for major adverse events after TAVR and did not prevent ischemic events any more than single therapy.
Based on this evidence, many centers changed their practice. And current European guidelines recommend a single antiplatelet drug for patients undergoing TAVR who do not have additional indications for oral anticoagulation therapy.
By the Numbers
Randomized trials are generally considered the best evidence for medical questions such as this one. “But randomized trials often do not reflect real-world reality. We have to look at what really happens,” Pelliccia said.
Retrospective data from registries can also provide large numbers of patients; in this case, TRITAVI provided data on thousands of patients rather than the hundreds examined in combined randomized trials.
“The results, for the first time, provide clinicians more information on how to treat their patients who are at high risk for bleeding and provide evidence that single antiplatelet therapy should be considered the standard of care in all patients undergoing TAVR,” Pelliccia said.

Rethinking the Scalpel: Advancing Non-Surgical Strategies for Early Breast Cancer
Breast cancer is the most common cancer in women worldwide and a leading cause of cancer-related deaths. The most common form of breast cancer is invasive ductal carcinoma, which accounts for 75%-80% of breast cancers. The second most common form is invasive lobular carcinoma, which accounts for 10%-15% of cases.
Surgical treatment of breast cancer involves removal and pathological staging of the cancerous tissue. Breast-conserving surgery and mastectomy are two surgical treatment options for patients with breast cancer. Breast-conserving surgery, which involves resection of the tumor and the surrounding margin of healthy tissue to achieve clean margins, is usually combined with radiotherapy. Mastectomy is considered in patients with relative and absolute contraindications to breast-conserving therapeutic options (eg, patients with a genetic predisposition to breast cancer, tumors > 5 cm, extensive margins, prior radiation to breast or chest wall, first-trimester pregnancy, extensive ductal carcinoma in situ, inflammatory breast cancer). Although surgical treatment of breast cancer is widely used, there have been calls to minimize unnecessary invasive surgical interventions in patients with early-stage breast cancer.
Reassessing the Role of Surgery in the Early Stages
Some surgical procedures, including axillary lymph node dissection (ALND) and contralateral prophylactic mastectomy (CPM), once considered standard treatment for early-stage breast cancer, are now being recognized as unnecessary in most cases of early-stage breast cancer without sentinel node metastases. Although ALND, which involves removal of all lymphatic tissue in the axilla, has been used for decades in the surgical management of early-stage breast cancer, this intervention typically results in lymphedema and significant morbidity.
Contralateral prophylactic mastectomy is a surgical option chosen by some women with early-stage unilateral breast cancer. However, this procedure is considered controversial in this patient population since evidence shows no survival advantage with CPM. A large-scale survey by Jagsi et al of female patients with in situ or early-stage breast cancer concluded that CPM was more common in patients who were White, had a higher level of education, and had private health insurance. In the study, 598 of the 1569 patients without an identified mutation or high genetic risk reported that a surgeon recommended against CPM. Of this group, only 1.9% underwent CPM. In contrast, of the 746 patients who reported that they did not receive any recommendation from a surgeon, 19% underwent CPM.
Re-excision and mastectomy are considered in patients with early-stage breast cancer when clear margins are not achieved with breast-conserving surgery. To prevent unnecessary reoperations and mastectomies, the 2013 invasive cancer margin consensus guideline by the American Society for Radiation Oncology (ASTRO) and the Society of Surgical Oncology, defined adequate margins in breast-conserving surgery in invasive breast cancer as “no ink on tumor.” The guideline is endorsed by the American Society of Breast Surgeons, ASTRO, and the St Gallen Consensus Conference.
A Shift in Practice: Moving Away From Routine Node Dissection
Based on findings from multiple clinical trials, experts recommend sentinel lymph node biopsy (SLNB) over ANLD and omit axillary surgery in certain patients. Findings from ACOSOG Z1071, SENTINA, and SN FNAC prospective multi-institutional trials support the use of SLNB as the initial diagnostic procedure. Sentinel lobe biopsy involves removal and evaluation of the first lymph node which receives lymphatic drainage from the breast cancer site. Negative biopsy findings on SLNB can avoid ALND as it is less likely that metastasis has occurred.
Although SLNB is preferred in younger patients with early-stage breast cancer, it is not routinely recommended for women aged ≥ 70 years of age with clinically node-negative, early-stage, HR-positive and HER2-negative breast cancer. This recommendation is based on study findings showing no difference in survival of women aged > 70 years with HR-positive clinical stage I breast cancer who did and did not undergo axillary evaluation.
The Z0011 trial by the American College of Surgeons Oncology Group found SLNB alone was not inferior to ALND regarding overall and disease-free survival in patients with clinically node-negative cancer undergoing breast conservation surgery and radiation therapy.
SLNB: A Less Invasive Alternative to ALND
Compared to SLNB, ALND is associated with more morbidity, physical symptoms, and poorer quality of life. A systemic review by Bakri et al evaluating the impact of ALND vs SLNB found higher rates of lymphedema, pain, reduced strength, and range of motion in patients who underwent ALND. In addition, an analysis of the National Cancer Database by Cocco et al found that patients with limited CN+ T1-2 breast cancer had favorable survival outcomes after undergoing SLNB and regional node irradiation vs ALND.
Rethinking First Steps: Non-Surgical Strategies
While surgical intervention with or without radiation therapy remains a primary treatment in early-stage breast cancer, there is an increased emphasis on de-escalation to minimize surgery and consider nonsurgical options in this patient population. A neoadjuvant systemic therapeutic approach by Kuerer et al for HER2-positive breast cancer and triple-negative breast cancer yielded a pathological complete response in 62% of patients. This multicenter, single-arm, phase 2 trial evaluated patients with HER2-positive breast cancer and a residual breast lesion < 2 cm or unicentric cT1-2N0-1M0 triple-negative breast cancer. Patients in the study underwent radiotherapy alone after excluding invasive in-situ disease.
The Clinician’s Role in Shaping Conservative Surgical Approaches
De-escalating surgery in breast cancer should involve acknowledging the patient’s fears and misperceptions regarding the risks of cancer recurrence that can lead them to opt for more invasive surgical treatments. Patients may not or fully regard the long-term effects of electing an invasive procedure in the absence of clinical indications. For example, patients undergoing more invasive interventions may experience worse body image and quality of life.
Clinicians may also not adequately estimate other harms associated with unnecessary surgical interventions. Providing clinicians with data that focuses on the psychological outcomes and satisfaction of patients post surgery may help them to better interpret and consider patient values and wishes and minimize future unnecessary surgeries.
Breast cancer remains one of the best-studied cancers with multiple high-quality randomized controlled trials supporting de-escalation of surgery. De-escalation of breast cancer surgery has been successful in multiple ways, including the implementation of ALND in early-stage breast cancer. However, other options such as CPM remain common. Proper patient and physician education involving data from clinical trials and reports of patient satisfaction may further decrease unnecessary surgical interventions.

Gastric Cancer Prevention: New AGA Update Reflects Latest High-Risk Screening and Surveillance Advice
Clinicians can help reduce gastric cancer incidence and mortality in high-risk groups through endoscopic screening and surveillance of precancerous conditions, such as gastric intestinal metaplasia (GIM), according to a new clinical practice update from AGA.
The update supports additional gastric guidance published so far in 2025, including a clinical guideline on the diagnosis and management of gastric premalignant conditions (GPMC) from the American College of Gastroenterology (ACG) and upper GI endoscopy quality indicators from ACG and the American Society for Gastrointestinal Endoscopy (ASGE).
“The synergy of these three publications coming out at the same time helps us to finally establish surveillance of high-risk gastric conditions in practice, as we do in the colon and esophagus,” said Douglas R. Morgan, MD, professor of medicine in gastroenterology and hepatology and director of Global Health programs in gastroenterology at the University of Alabama at Birmingham.
Morgan, who wasn’t involved with the AGA update, served as lead author for the ACG guideline and co-author of the ACG-ASGE quality indicators. He also co-authored the 2024 ACG clinical guideline on treating Helicobacter pylori infection, which has implications for gastric cancer.
“The AGA and ACG updates provide detail, while the QI document is an enforcer with medical, legal, and reimbursement implications,” he said. “We have an alignment of the stars with this overdue move toward concrete surveillance for high-risk lesions in the stomach.”
The clinical practice update was published in Gastroenterology.
Gastric Cancer Screening
, the authors wrote. The top ways to reduce mortality include primary prevention, particularly by eradicating H pylori, and secondary prevention through screening and surveillance.
High-risk groups in the United States should be considered for gastric cancer screening, including first-generation immigrants from high-incidence regions and potentially other non-White racial and ethnic groups, those with a family history of gastric cancer in a first-degree relative, and those with certain hereditary GI polyposis or hereditary cancer syndromes.
Endoscopy remains the best test for screening or surveillance of high-risk groups, the authors wrote, since it allows for direct visualization to endoscopically stage the mucosa, identify any concerning areas of neoplasia, and enable biopsies. Both endoscopic and histologic staging are key for risk stratification and surveillance decisions.
In particular, clinicians should use a high-definition white light endoscopy system with image enhancement, gastric mucosal cleansing, and insufflation to see the mucosa. As part of this, clinicians should allow for adequate visual inspection time, photodocumentation, and systematic biopsy protocol for mucosal staging, where appropriate.
As part of this, clinicians should consider H pylori eradication as an essential adjunct to endoscopic screening, the authors wrote. Opportunistic screening for H pylori should be considered in high-risk groups, and familial-based testing should be considered among adult household members of patients who test positive for H pylori.
Endoscopic Biopsy and Diagnosis
In patients with suspected gastric atrophy — with or without GIM — gastric biopsies should be obtained with a systematic approach, the authors wrote. Clinicians should take a minimum of five biopsies, sampling from the antrum/incisura and corpus.
Endoscopists should work with their pathologists on consistent documentation of histologic risk-stratification parameters when atrophic gastritis is diagnosed, the authors wrote. To inform clinical decision-making, this should include documentation of the presence or absence of H pylori infection, severity of atrophy or metaplasia, and histologic subtyping of GIM.
Although GIM and dysplasia are endoscopically detectable, these findings often go undiagnosed when endoscopists aren’t familiar with the characteristic visual features, the authors wrote. More training is needed, especially in the US, and although artificial intelligence tools appear promising for detecting early gastric neoplasia, data remain too preliminary to recommend routine use, the authors added.
Since indefinite and low-grade dysplasia can be difficult to identify by endoscopy and accurately diagnosis on histopathology, all dysplasia should be confirmed by an experienced gastrointestinal pathologist, the authors wrote. Clinicians should refer patients with visible or nonvisible dysplasia to an endoscopist or center with expertise in gastric neoplasia.
Endoscopic Management and Surveillance
If an index screening endoscopy doesn’t identify atrophy, GIM, or neoplasia, ongoing screening should be based on a patient’s risk factors and preferences. If the patient has a family history or multiple risk factors, ongoing screening should be considered. However, the optimal screening intervals in these scenarios aren’t well-defined.
Patients with confirmed gastric atrophy should undergo risk stratification, the authors wrote. Those with severe atrophic gastritis or multifocal/incomplete GIM would likely benefit from endoscopic surveillance, particularly if they have other risk factors such as family history. Surveillance should be considered every 3 years, though shorter intervals may be advisable for those with multiple risk factors such as severe GIM.
Patients with high-grade dysplasia or early gastric cancer should undergo endoscopic submucosal dissection (ESD), with the goal of en bloc, R0 resection to enable accurate pathologic staging and the intent to cure. Eradicating active H pylori infection is essential — but shouldn’t delay endoscopic intervention, the authors wrote.
In addition, patients with a history of successfully resected gastric dysplasia or cancer should undergo endoscopic surveillance. Although post-ESD surveillance intervals have been suggested in other recent AGA clinical practice updates, additional data are needed, particularly for US recommendations, the authors wrote.
Although type 1 gastric carcinoids in patients with atrophic gastritis are typically indolent, especially if less than 1 cm, endoscopists may consider resecting them and should resect lesions between 1and 2 cm. Patients with lesions over 2 cm should undergo cross-sectional imaging and be referred for surgical resection, given the risk for metastasis.
Patient-Centered Approach
The guideline authors suggested thinking about screening and surveillance on a patient-level basis. For instance, only those who are fit for endoscopic or potentially surgical treatment should be screened for gastric cancer and continued surveillance of GPMC, they wrote. If a person is no longer fit for endoscopic or surgical treatment, whether due to life expectancy or other comorbidities, then screening should be stopped.
In addition, to achieve health equity, clinicians should take a personalized approach to assess a patient’s risk for gastric cancer and determine whether to pursue screening and surveillance, the authors wrote. Modifiable risk factors — such as tobacco use, high-salt and processed food diets, and lack of health care — should also be addressed, since most of these risk factors disproportionately affect high-risk patients and represent healthcare disparities, they added.
“This update provides clinicians with a framework for understanding the natural history and epidemiology of gastric polyps, as well as guidance on best practices for the endoscopic detection and classification of gastric polyps, best practices for the endoscopic resection of gastric polyps, and best practices for endoscopic surveillance following resection,” said Hashem El-Serag, MD, professor and chair of medicine at the Baylor College of Medicine and director of the Texas Medical Center Digestive Diseases Center in Houston.
El-Serag, who wasn’t involved with the clinical practice update, has researched and published on consensus around the diagnosis and management of GIM.
“Stomach polyps are commonly found during routine endoscopic procedures. They are mostly asymptomatic and incidental, and therefore, clinicians may not be prepared ahead of time on how to deal with them,” he said. “The appropriate management requires proper identification and sampling of the polyp features and the uninvolved gastric mucosa, as well as a clear understanding of the risk factors and prognosis. Recent changes in the epidemiology and endoscopic management of gastric polyps makes this update timely and important.”
The update received no particular funding. The authors disclosed receiving grant support, having consultant relationships with, and serving in advisory roles for numerous pharmaceutical, biomedical, and biotechnology firms. Morgan and El-Serag reported having no relevant disclosures.
