SAN DIEGO — Molecular residual disease (MRD) positivity, as detected via circulating tumor (ct) DNA following curative resection, was significantly associated with improved disease-free survival after chemotherapy in patients with stage II or III colorectal cancer (CRC), 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.”

Magee is an employee of Nater. Grady has been on the scientific advisory boards for Guardant Health and Freenome and has consulted for Karius.

SAN DIEGO — Patients with cirrhosis treated with sodium-glucose cotransporter 2 (SGLT2) inhibitors show significant reductions in a range of portal hypertension complications and all-cause mortality compared with those not receiving the drugs, 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.

“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.

SAN DIEGO — An artificial intelligence (AI)–enhanced digital collaborative care model led to rapid, clinically significant, and sustained symptom relief for patients with irritable bowel syndrome (IBS) 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.

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

Gastric cancer remains a leading cause of preventable cancer and mortality in certain US populations, 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.

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

Gastric cancer remains a leading cause of preventable cancer and mortality in certain US populations, 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.
