PARP inhibitors and breast cancer: Questions remain about wider use
oncologists explained at the European Society for Medical Oncology Breast Cancer annual congress.
For now, the drugs are only approved in high-risk germline BRCA mutation (gBRCAmut) early breast cancer, oncologist Kevin Punie, MD, of Saint Augustine Hospital in Wilrijk, Belgium, said during a session at the meeting. Combining the drugs with chemotherapy “has not yet demonstrated significant benefits, and this is irrespective whether platinum was part of the chemotherapy backbone.”
PARP is a kind of enzyme that repairs damaged DNA in cells, especially cancerous ones. PARP inhibitors block the enzyme, potentially leading more cancer cells to die, the Dana-Farber Cancer Institute states.
In a separate presentation during the same session, oncologist Andrew Tutt, MBChB, PhD, noted that a study he led – a phase 3, double-blinded, randomized 2021 trial – found that patients with BRCA1- or BRCA2-mutated breast cancer who took the PARP inhibitor olarapib (Lynparza) versus placebo had improved outcomes on several measures, including 3-year invasive disease-free survival (85.9% vs. 77.1%, P < .001). However, the study noted that “olaparib had limited effects on global patient-reported quality of life.”
Dr. Tutt, of the Institute of Cancer Research, London, and Kings College London, said 57% of patients who took olarapib suffered nausea versus 24% of those who took placebo, and fatigue and anemia were also more common in the olarapib group. Anemia can be severe and lead to transfusions in some cases.
As Dr. Punie explained, there are many reasons to consider combining PARP inhibitors with other treatments such as chemotherapy, immunotherapy, and radiotherapy. The combinations may have synergetic effects, and they could have potential in both the neoadjuvant and adjuvant settings.
The combination of the PARP inhibitor olaparib and endocrine therapy is now approved by the European Medicines Agency for the adjuvant treatment of certain patients with germline BRCA1/2 mutations who have HER2-negative, high-risk early breast cancer, Dr. Punie noted.
The 2021 study led by Dr. Tutt reported that treatment or safety differences were found in those who received both olaparib and endocrine therapy versus those who only received olarapib.
So far, Dr. Punie said, “we not yet have enough clinical evidence to say that there’s really synergy between PNP inhibitors and other anticancer therapies.” According to the National Institutes of Health, medical synergy “describes the interaction of two or more drugs when their combined effect is greater than the sum of the effects seen when each drug is given alone.”
In regard to chemotherapy, it makes sense that PARP inhibitors would be helpful in combination, Dr. Punie said. DNA damage to cancer cells accumulates during chemotherapy, he said, and they’re more depending on PARP for repair.
Study results so far have been mixed. A 2022 study, for example, found that adding the experimental PARP inhibitor veliparib to the chemotherapy regimen carboplatin-paclitaxel didn’t improve outcomes, he said. A similar study examining the addition of olaparib to carboplatin-paclitaxel is ongoing.
As for combining radiotherapy and PARP inhibitors, Dr. Punie said that preclinical findings are promising, and research is underway. There’s also ongoing research into combining PARP inhibitors with immunotherapy.
Off-label use of olaparib with immunotherapy or sequential treatment may be appropriate in the setting of adjuvant gBRCAmut triple-negative breast cancer with residual disease, he said.
During his presentation, Dr. Tutt called for researchers to investigate the use of PARP inhibitors in the de-escalation of treatment in lower-risk gBRCAmut disease.
“Clearly, some patients require chemotherapy, and we know patients respond very well to neoadjuvant chemotherapy if they have a BRCA mutation, but we don’t yet know who we can de-escalate in,” he said.
He also highlighted the need to reduce anemia in patients on PARP inhibitors, “particularly if we’re moving into lower-risk populations or possibly considering prevention trials.
“The study of PARP inhibitor resistance ... is now urgent, so that we can address it,” he said.
Dr. Punie disclosed financial relationships with AstraZeneca, Eli Lilly, Exact Sciences, Focus Patient, Medscape, MSD, Mundi Pharma, Need, Novartis, Pierre Fabre, Pfizer, F. Hoffmann–La Roche, Sanofi, Seagen, and PharmaMar. Dr. Tutt disclosed financial relationships with Artios, Gilead, MD Anderson, Merck KGaA, Pfizer, Vertex, AstraZeneca, EM Partners, Medscape Education, CRUK, Inbiomotion, Myriad Genetics, and Breast Cancer Now.

Mailed HPV test kits boost cervical cancer screening
The self-sampling kits, which detect human papillomavirus (HPV), are available only for use in clinical trials, but the researchers hope that eventually these kits will be approved for use by the general public.
The researchers, from the University of North Carolina, explored use of these kits in the My Body, My Test-3 study, which was published online in The Lancet Public Health.
In a commentary published with the study, Runzhi Wang, MD, and Jennell Coleman, MD, MPH, both of Johns Hopkins University, Baltimore, said it “provides the required evidence that ... self-collected samples can be an effective strategy for hard-to-reach populations.”
The study involved 665 women (aged 25-64) in North Carolina who were either uninsured or enrolled in Medicaid or Medicare. The patients had low-income backgrounds and lived in urban areas. More than half self-reported as Black or Hispanic (55%), uninsured (78%) or unemployed (57%). None had a Pap smear in at least 4 years or a high-risk HPV test in the last 6 years.
Two-thirds of the women were mailed an HPV self-collection kit and received assistance with scheduling an in-person screening appointment. The kit included a Viba-Brush device, which is inserted into the vagina like a tampon to collect the sample.
The other third of women, the control group, only received scheduling assistance.
The team found that mailing the self-collection tests along with helping women book in-clinic appointments improved screening rates twofold, compared with just assisting patients to schedule an appointment.
Screening success among those who received the at-home collection kit was 72%, compared with 37% in the control group.
Of those who received the kits, 78% returned them. This is “impressive,” said Dr. Wang and Dr. Coleman, as previous studies have reported return rates of only 8%-20%.
About 23% of eligible women are overdue for cervical cancer screening by at least a year, according to the National Cancer Institute. Jennifer Smith, PhD, MPH, professor of epidemiology at the University of North Carolina at Chapel Hill and an author of the study, believes every woman deserves equal access to cervical screening.
“I think we really need to make efforts to increase cervical cancer screening among women who are overdue for screening by a year or more from the recommended guidelines,” Dr. Smith said. “We’ve proven along with the wide evidence both in the U.S. and globally that self-collection intervention works well and can motivate screening uptake by breaking down barriers for populations that have less access to care.”
“We’re hoping this research in combination with all of the extensive evidence on the positive performance of HPV self-collection will provide additional information to be considered by the FDA for approval of the kits for primary screening,” Dr. Smith said. 
“Government approval of at-home HPV tests would have a huge impact,” said coauthor Noel Brewer, PhD, also of UNC Chapel Hill. “We could better reach those in rural areas where cervical cancer screening is hard to come by.”
Dr. Smith has received research grants, supply donations, and consultancies for Hologic and BD Diagnostics. Dr. Brewer, Dr. Wang, and Dr. Coleman reported no conflicts of interest.

Expunging ‘penicillin allergy’: Your questions answered
Last month, I described a 28-year-old patient with a history of injection drug use who presented with pain in his left forearm. His history showed that, within the past 2 years, he’d been seen for cutaneous infections multiple times as an outpatient and in the emergency department. His records indicated that he was diagnosed with a penicillin allergy as a child when he developed a rash after receiving amoxicillin. I believed the next course of action should be to test for a penicillin allergy with an oral amoxicillin challenge.
Thank you for your excellent questions regarding this case. Great to hear the enthusiasm for testing for penicillin allergy!
One question focused on the course of action in the case of a mild or moderate IgE-mediated reaction after a single dose test with amoxicillin. Treatment for these reactions should include an antihistamine. I would reserve intravenous antihistamines for more severe cases, which also require treatment with a course of corticosteroids. However, the risk for a moderate to severe reaction to amoxicillin on retesting is quite low.
Clinicians need to exercise caution in the use of systemic corticosteroids. These drugs can be lifesaving, but even short courses of corticosteroids are associated with potentially serious adverse events. In a review of adverse events associated with short-course systemic corticosteroids among children, the rate of vomiting was 5.4%; behavioral change, 4.7%; and sleep disturbance, 4.3%. One child died after contracting herpes zoster, more than one-third of children developed elevated blood pressure, and 81.1% had evidence of suppression of the hypothalamic-pituitary-adrenal axis.
Among adults, short courses of systemic corticosteroids are associated with acute increases in the risks for gastrointestinal bleeding and hypertension. Cumulative exposure to short courses of corticosteroids over time results in higher risks for obesity, type 2 diabetes, and osteoporosis.
Another question prompted by this young man’s case focused on the durability of IgE reactions against penicillin. The IgE response to penicillin does indeed wane over time; 80% of patients with a previous true penicillin allergy can tolerate the antibiotic after 10 years. Thus, about 95% of patients with a remote history of penicillin allergy are tolerant of penicillin, and testing can be performed using the algorithm described.
Clinicians should avoid applying current guidelines for the evaluation of patients with penicillin allergy to other common drug allergies. The overall prevalence of sulfonamide allergy is 3%-8%, and the vast majority of these reactions follow treatment with trimethoprim-sulfamethoxazole. Sulfa allergy is even more common among persons living with HIV infection. The natural history of sulfa allergy is not as well established as penicillin allergy. Allergy testing is encouraged in these cases. Graded oral challenge testing is best reserved for patients who are unlikely to have a true sulfa allergy based on their history.

Investigational drug peresolimab shows efficacy in patients with RA
(RA), according to results from a phase 2 clinical trial.
After 12 weeks, patients receiving peresolimab 700 mg saw a greater improvement in the primary endpoint of change in Disease Activity Score for 28 joints based on C-reactive protein (DAS28-CRP), compared with placebo.
“These results provide evidence that stimulation of the PD-1 receptor has potential efficacy in the treatment of rheumatoid arthritis,” said the authors, led by Jay Tuttle, PhD, of Eli Lilly and Company. The study was published in the New England Journal of Medicine.
A total of 98 patients with treatment-resistant, moderate to severe RA were enrolled in the double-blind, placebo-controlled trial. All patients had previously experienced treatment failure with biologic, targeted synthetic, or conventional synthetic disease-modifying antirheumatic drugs. Patients were randomized to receive 700 mg of peresolimab (49 patients), 300 mg of peresolimab (25 patients), or placebo (24 patients) intravenously once every 4 weeks.
Only patients taking peresolimab 700 mg had a significantly greater change in DAS28-CRP scores after 12 weeks, compared with placebo. In secondary outcomes, 71% of the 700-mg group experienced an improvement of at least 20% in American College of Rheumatology response criteria (ACR20), as compared with 42% in the placebo group. There was no difference between the placebo and peresolimab groups in ACR50 or ACR70 responses.
The safety profiles were similar across all three groups, although the 700-mg peresolimab group had numerically more adverse events (n = 14) than the 300-mg peresolimab group (n = 8) and the placebo group (n = 9). There were no severe adverse events reported during the study period. The authors noted that larger and longer studies are necessary to understand the safety of peresolimab.
“Careful evaluation of the effect of peresolimab on the risk of cancer will be important given the efficacy of PD-1 inhibitors in oncologic disease,” the authors wrote.
Eli Lilly funded the research. Researchers disclosed financial relationships with AbbVie, Eli Lilly, Janssen, Novartis, Pfizer, and several other pharmaceutical companies.

In secondary outcomes, 71% of the 700-mg group experienced an improvement of at least 20% in American College of Rheumatology response criteria (ACR20), as compared with 42% in the placebo group. There was no difference between the placebo and peresolimab groups in ACR50 or ACR70 responses.
The safety profiles were similar across all three groups, although the 700-mg peresolimab group had numerically more adverse events (n = 14) than the 300-mg peresolimab group (n = 8) and the placebo group (n = 9). There were no severe adverse events reported during the study period. The authors noted that larger and longer studies are necessary to understand the safety of peresolimab.
“Careful evaluation of the effect of peresolimab on the risk of cancer will be important given the efficacy of PD-1 inhibitors in oncologic disease,” the authors wrote.

(RA), according to results from a phase 2 clinical trial.
After 12 weeks, patients receiving peresolimab 700 mg saw a greater improvement in the primary endpoint of change in Disease Activity Score for 28 joints based on C-reactive protein (DAS28-CRP), compared with placebo.
“These results provide evidence that stimulation of the PD-1 receptor has potential efficacy in the treatment of rheumatoid arthritis,” said the authors, led by Jay Tuttle, PhD, of Eli Lilly and Company. The study was published in the New England Journal of Medicine.
A total of 98 patients with treatment-resistant, moderate to severe RA were enrolled in the double-blind, placebo-controlled trial. All patients had previously experienced treatment failure with biologic, targeted synthetic, or conventional synthetic disease-modifying antirheumatic drugs. Patients were randomized to receive 700 mg of peresolimab (49 patients), 300 mg of peresolimab (25 patients), or placebo (24 patients) intravenously once every 4 weeks.
Only patients taking peresolimab 700 mg had a significantly greater change in DAS28-CRP scores after 12 weeks, compared with placebo. In secondary outcomes, 71% of the 700-mg group experienced an improvement of at least 20% in American College of Rheumatology response criteria (ACR20), as compared with 42% in the placebo group. There was no difference between the placebo and peresolimab groups in ACR50 or ACR70 responses.
The safety profiles were similar across all three groups, although the 700-mg peresolimab group had numerically more adverse events (n = 14) than the 300-mg peresolimab group (n = 8) and the placebo group (n = 9).

Study explains link between fatty liver and CRC liver metastasis
according to the authors of new research.
These findings support the previously reported link between fatty liver and colorectal cancer (CRC) liver metastasis, and suggest that CRC patients with nonalcoholic fatty liver disease (NAFLD) may respond differently to treatment than CRC patients without NAFLD, wrote lead author Zhijun Wang, MD, PhD, of Cedars-Sinai Medical Center, Los Angeles, and colleagues, in their paper.
“Obesity and NAFLD are the significant risk factors for CRC,” the investigators explained, in Cell Metabolism. “A growing body of epidemiological evidence indicates that fatty liver increases the occurrence of CRC liver metastasis and the local recurrence after resection of CRC liver metastases, thereby worsening prognosis ... There is an urgent need to understand the molecular mechanisms of metastasis in patients with fatty liver to manage those patients effectively.”
To this end, Dr. Wang and colleagues conducted a series of experiments involving mice, cell cultures, and human sera. They found that fatty liver increases risk of CRC liver metastasis via extracellular vesicles (EVs) that contain procarcinogenic miRNAs. As these EVs transfer microRNAs from fatty liver hepatocytes to metastatic cancer cells, YAP activity increases, which, in turn, suppresses immune activity within the tumor microenvironment, promoting growth of CRC metastasis.
Beyond the increased risk of liver metastasis presented by fatty liver, the investigators suggested that NAFLD may cause “more complex” metastatic tumor microenvironments, potentially explaining “diverse responses” to cancer therapies among patients with CRC and liver metastases.
“In summary, our study demonstrates that the pre- and prometastatic liver environment of fatty liver is induced by procarcinogenic EVs and results in an immunosuppressive tumor microenvironemnt, in which YAP plays an important role,” the investigators concluded. “Our study provides new insight into [the] distinct liver tumor microenvironment in patients with fatty liver and without fatty liver, which may contribute to the aggressiveness of metastatic tumors and weak responses to anticancer therapy in patients with fatty liver. Additional studies are warranted to develop precision medicine for treating patients with CRC and liver metastasis.”
One of the study authors disclosed relationships with Altimmune, Cytodyn, Novo Nordisk, and others. The other investigators had no relevant financial disclosures.

Brepocitinib shows promise for psoriatic arthritis patients
The investigational drug brepocitinib showed superior symptom reduction in adults with moderate to severe active psoriatic arthritis (PsA), compared with placebo, by meeting primary and secondary endpoints of a phase 2b trial at 16 weeks, which persisted out to 1 year, according to data from 218 individuals.
Brepocitinib, a combination tyrosine kinase 2 and Janus kinase 1 inhibitor, is being studied for the treatment of several immunologic diseases including PsA, wrote Philip Mease, MD, of the Swedish Medical Center/Providence St. Joseph Health and the University of Washington, both in Seattle.
Previous studies in patients with PsA support the use of Janus kinase inhibitors and demonstrate the efficacy of tyrosine kinase 2 inhibitors, but more data are needed in patients with active PsA, the researchers noted.
In a study published in Arthritis & Rheumatology, the researchers randomized adults aged 18-75 years with moderate to severe PsA to once-daily oral doses of brepocitinib at 10 mg, 30 mg, or 60 mg, or a placebo for 16 weeks to assess safety, efficacy, and dose response. Placebo-treated patients were advanced to 30 mg or 60 mg of brepocitinib at week 16. Baseline demographics and disease characteristics were similar among the treatment groups. The mean Psoriatic Arthritis Disease Activity Score (PASDAS) and Disease Activity Index for PsA scores were 5.6 and 38.2, respectively, for the overall study population. Approximately two-thirds (64.7%) had a baseline Psoriasis Area and Severity Index (PASI) score greater than 0 and 3% or more of their body surface area affected by psoriasis.
The primary endpoint was the proportion of patients achieving 20% improvement in American College of Rheumatology response criteria (ACR 20) at week 16. Secondary endpoints included rates of patients meeting ACR 50 and ACR 70 response criteria, the proportion of patients achieving 75% and 90% improvement in PASI scores (PASI 70 and 90), as well as the rates of patients meeting Minimal Disease Activity (MDA) criteria at 16 and 52 weeks.
At week 16, ACR 20 response rates were significantly higher in the brepocitinib 30-mg and 60-mg groups, compared with the placebo group (66.7% and 74.6%, respectively, vs. 43.3%), but not for those who received brepocitinib 10 mg (64.5%).
Response rates for ACR 50, ACR 70, PASI 75, PASI 90, and MDA were similarly higher in the 30-mg and 60-mg brepocitinib groups, compared with placebo, and these responses persisted at week 52. Notably, significant differences in PASI 75 and PASI 90 were observed in patients taking 30 mg and 60 mg brepocitinib, compared with placebo, as early as weeks 4 and 8, respectively, the researchers said.
In addition, disease activity based on PASDAS improved significantly more from baseline to week 16 in all brepocitinib groups, compared with placebo.
The overall safety data were consistent with previous brepocitinib studies, and most of the adverse events were mild or moderate, the researchers said. A total of 12 participants (5.5%) experienced a total of 15 serious adverse events, including 6 infections with brepocitinib 30 mg or 60 mg. No major adverse cardiovascular events or deaths occurred during the study period.
The findings were limited by several factors, including the use of clinics in a limited geographic area (11 countries in Europe), small sample size, and mainly White population, the researchers noted. Other limitations included the large placebo effect and relatively short placebo-controlled period.
The study was supported by Pfizer. Dr. Mease disclosed relationships with Pfizer and other companies including AbbVie, Amgen, Bristol-Myers Squibb, Boehringer Ingelheim, Galapagos, Gilead, GlaxoSmithKline, Inmagene, Janssen, Lilly, Novartis, Sun, and UCB.

Analysis: 40% of information about cirrhosis on TikTok is incorrect
CHICAGO –
TikTok’s short video format is increasingly becoming a major source for news and information, especially for adolescents and young adults. In 2022 the technology news website The Verge reported that about 10% of all U.S. adults regularly get news from TikTok, including an estimated 26% of adults under 30.
“Our study highlights the alarming prevalence of misinformation related to liver disease and cirrhosis on the TikTok platform. This misinformation can potentially lead to harm and poor health outcomes for individuals seeking accurate information about their conditions,” wrote the study authors in their abstract.
The study, which was led by Macklin Loveland, MD, an internal medicine resident at the University of Arizona, Tucson, found that, among 2,223 TikTok posts related to liver disease or cirrhosis as of November 2022, 60.3% were found to have accurate medical information, but the remaining 39.7% contained misinformation.
Some of the misinformation offered highly dubious and potentially dangerous advice, such as “Reishi mushrooms can reverse liver damage,” when in fact there is evidence to suggest that reishi mushrooms, especially in powder form, may be toxic to the liver and may even cause fatal fulminant hepatitis.
In an interview, Dr. Loveland said that much of the good information about liver disease on TikTok seems to come from patients with cirrhosis or other liver diseases who post videos chronicling their experiences, whereas bad information seems to come from people who are trying to pitch a product such as “natural” or “alternative” medicine.
“People who have real-life, firsthand experiences with cirrhosis have a really nice platform to talk about their disease process and share information with other people with similar disease processes, and the majority of them are accurate,” he said. “Where the inaccuracies come in are when people are trying to profit off a product or sell a dietary supplement, and then things go by the wayside.”
It’s important for TikTok users to understand the intentions of other users, he said, and expressed the hope that content mediators within TikTok would help to keep misinformation at bay.
Skyler B. Johnson, MD, assistant professor of radiation oncology at the University of Utah Huntsman Cancer Institute, Salt Lake City, has studied misinformation about cancer on social media, and as he and colleagues reported in the Journal of the National Cancer Institute, of 200 articles on cancer posted on social media sites, 32.5% contained misinformation and 30.5% contained harmful information.
In an interview, Dr. Johnson, who was not involved in the study by Dr. Loveland and colleagues, offered advice for colleagues about countering misinformation.
“What we’re trying to do, as part of our research group, is encourage physicians to take an active role in addressing misinformation with their patients and also in their social networking interactions,” he said. “When I see a new patient with a new diagnosis of cancer, I warn them that they’re going to encounter things online that may or may not be true.”
He noted that, often when physicians instruct patients not to go online to research their disease, the first thing the vast majority of patients do after leaving the office is to jump online.
Instead, Dr. Johnson recommended inoculating patients against misinformation – not to discourage them from going online, but to inform them about the myriad good and bad information sources, and steer them toward trustworthy sites such as government agencies (the National Institutes of Health, Centers for Disease Control and Prevention, etc), academic medical center sites, or select nonprofit organizations, foundations, and medical associations.
“But at the end of the day, even those you have to be somewhat vigilant about, because there are some unscrupulous providers who exploit even those sites,” he added.
Study details
Dr. Loveland and colleagues used the TikTok search engine to look for posts containing the terms “cirrhosis” and “liver disease,” and watched all such videos that turned up in the search from beginning to end. They classified each post as either educational in intent or whether it depicted a firsthand experience with liver disease.
They determined whether each post was accurate or erroneous according to guidelines from the American Association for the Study of Liver Disease, American College of Gastroenterology, and American Gastroenterological Association. They also recorded the number of likes, comments, and the number of times that each video was shared.
Accurate posts were viewed and liked significantly more often than inaccurate ones, and accurate posts had significantly more comments that faulty posts.
However, both accurate and inaccurate posts were shared a similar number of times, suggesting that bad-quality information can metastasize just as easily as good information can be disseminated.
Dr. Loveland and colleagues echoed the recommendations of Dr. Johnson, stating that “health care provides should be aware of the potential for misinformation on social media and should strive to provide their patients with accurate and evidence-based information to inform their health care decisions.”
The study was internally funded. Dr. Loveland and Dr. Johnson reported having no conflicts of interest to disclose.

Instead, Dr. Johnson recommended inoculating patients against misinformation – not to discourage them from going online, but to inform them about the myriad good and bad information sources, and steer them toward trustworthy sites such as government agencies (the National Institutes of Health, Centers for Disease Control and Prevention, etc), academic medical center sites, or select nonprofit organizations, foundations, and medical associations.
“But at the end of the day, even those you have to be somewhat vigilant about, because there are some unscrupulous providers who exploit even those sites,” he added.
Study details
Dr. Loveland and colleagues used the TikTok search engine to look for posts containing the terms “cirrhosis” and “liver disease,” and watched all such videos that turned up in the search from beginning to end. They classified each post as either educational in intent or whether it depicted a firsthand experience with liver disease.
They determined whether each post was accurate or erroneous according to guidelines from the American Association for the Study of Liver Disease, American College of Gastroenterology, and American Gastroenterological Association. They also recorded the number of likes, comments, and the number of times that each video was shared.
Accurate posts were viewed and liked significantly more often than inaccurate ones, and accurate posts had significantly more comments that faulty posts.
However, both accurate and inaccurate posts were shared a similar number of times, suggesting that bad-quality information can metastasize just as easily as good information can be disseminated.
Dr. Loveland and colleagues echoed the recommendations of Dr. Johnson, stating that “health care provides should be aware of the potential for misinformation on social media and should strive to provide their patients with accurate and evidence-based information to inform their health care decisions.”
The study was internally funded. Dr. Loveland and Dr. Johnson reported having no conflicts of interest to disclose.

Misdiagnosis, mismatch still common in pancreatic cystic neoplasms
CHICAGO – , data from a retrospective study show.
An analysis of all pancreatic resections performed for presumed PCN at the Verona Pancreas Institute, Italy, from 2011 through 2020 showed a high degree of discrepancy between the preoperative clinical diagnosis and the final postoperative pathology, with some lesions being misdiagnosed in nearly two-thirds of cases, reported Anna Burelli, MD, of the department of general and pancreatic surgery at the University of Verona.
“Diagnostic errors are still common for resected PCNs. Morphological and clinical information alone still poorly frame actual targets for surgery, and hopefully the development of new reliable biomarkers will represent the next evolution in pancreatic cystic neoplasm management,” she said in an oral abstract session at the annual Digestive Disease Week® (DDW).
Diagnostic errors are significant issues in care of patients with PCN, because clinicians must balance the need for prompt, definitive treatment when necessary with the need for avoiding the significant morbidity of pancreatic resection for patients with lesions that turn out to be nonmalignant.
The investigators define “misdiagnosis” as a discrepancy between the preoperative clinical diagnosis and the postoperative pathology, and “mismatch” as a discrepancy between the preoperative suspicion of malignant or benign disease and the final pathology.
Checkered history
In previous cases series from Massachusetts General Hospital in Boston (2010) and the Verona Pancreas Institute (2012) – both experienced, high-volume centers – PCN misdiagnosis rates were 30% and 21%, respectively, and results from the current study show that things haven’t changed much since then, Dr. Burelli said.
PCNs are divided into neoplastic and nonneoplastic categories, with mucin-producing subtypes considered to be precancerous lesions that require accurate diagnosis and close monitoring.
Examples of neoplastic PCNs are intraductal papillary mucinous neoplasms (IPMNs) of the main pancreatic duct or side branch and mucinous cystadenomas. In contrast, serous cystadenomas, considered nonneoplastic, are mostly benign lesions discovered incidentally during abdominal imaging for another indication. It is very difficult, however, to distinguish between the two PCN subtypes clinically.
For example, Dr. Burelli showed images from a patient who received a preoperative diagnosis of mixed IPMN that was in fact found to be chronic pancreatitis on postoperative pathology.
Dr. Burelli noted that AGA and joint European guidelines for management of PCNs have been updated over the past decade, with the latest AGA iteration in 2015.
A 2017 study evaluating the 2015 AGA guidelines for management of asymptomatic PCNs found that following the guidelines in a large multicenter cohort “would have resulted in 60 % fewer patients being referred for surgical resection, and accurately recommended surveillance in 95% of patients with asymptomatic PCNs.”
Misdiagnosis and mismatch common
In the current study, Dr. Burelli and colleagues reviewed all pancreatic resections performed for PCNs at their center from 2011 through 2020.
Of 601 patients included in the retrospective study, 301 underwent endoscopic ultrasound (EUS).
The investigators identified misdiagnosis in 19% of cases and mismatch in 34%, and there was no significant improvement in diagnostic accuracy among the 50% of patients who underwent EUS.
The most frequently misdiagnosed lesions were cystic neuroendocrine tumors, in 61% of cases. The least misdiagnosed lesions were pseudopapillary tumors, in 6% of cases.
Many of the diagnostic errors were clinically important. For example, seven cases presumed to be serous cystic neoplasms (an almost always benign lesion) were found on final pathology to have a different, malignant histology.
Mismatch examples included 50 IPMNs with high-risk stigmata that were presumed to be malignant before surgery but were nonmalignant on final pathology, and 38 IPMNs without high-risk stigmata which were thought on clinical examination to be benign but turned out to be malignant on final pathology.
“Our results are in line with the current literature,” Dr. Burelli said, citing a recent meta-analysis showing that among 3,292 patients who underwent resection for mucinous cystic neoplasms (MCNs), the pooled rate of malignancy was 16.1%, yet the 2012 International Association of Pancreatology guidelines recommend surgery for all fit patients with MCNs, and joint European evidence-based guidelines from 2018 recommend surgery for MCNs 40 mm or larger, those with mural nodules, and for patients who are symptomatic.
The 16.1% pooled malignancy rate suggests “that there is space for surveillance in most cases of MCNs,” she said.
In addition, morphologic and clinical evaluation for IPMN with high-risk stigmata have been shown to have low specificity and low sensitivity, “so should guideline recommendations be revised?” Dr. Burelli said.
She pointed to a recent multi-institutional study in Gastroenterology showing that real-time next-generation sequencing of pancreatic cyst fluid “is sensitive and specific for various pancreatic cyst types and advanced neoplasia arising from mucinous cysts, but also reveals the diversity of genomic alterations seen in pancreatic cysts and their clinical significance.”
“This is not the future; this is the present,” she concluded.
Invited discussant R. Matthew Walsh, MD, a surgeon specializing in pancreatic and cancer surgery at the Cleveland Clinic, complimented the contributions of her group.
“The patient that you showed with chronic pancreatitis could have very well benefited from the operation regardless of the diagnosis if they were symptomatic,” he said, addressing Dr. Burelli. “So what is the group that is the regrettable surgical patients, and where are you aiming your studies? Is it really the 24% with high-risk features in IPMN that have low-grade dysplasia, or is it the 58% who we’re not sure why they were operated on because they didn’t have high-grade features who had low-grade dysplasia?”
She replied that “the goal here is to avoid surgery for benign entities, and we know that the only true benign entities are serous cystic neoplasms, and all the others have a malignant potential, but we think at Verona Pancreas Institute there is no reason to operate on low-grade dysplasia free patients. This is what we really would like to avoid.”
Dr. Walsh also asked, given their finding that EUS did not appear to offer a benefit to patients or change decision making, which patients should still get EUS.
“I think that only patients in which the diagnosis is uncertain or in which there are some worrisome features or high-risk stigmata should undergo EUS before surgery, and also to continue follow-up,” Dr. Burelli said. “I don’t think that the conclusion is that EUS is not useful, but it’s not useful in all.”
For example, large, microcystic lesions can be readily identified radiographically, but other, more complex cases may still require EUS to help nail down or refine a diagnosis, she said.
The study was internally funded. Dr. Burelli and Dr. Walsh reported having no conflicts of interest.

Emotional eating isn’t all emotional
“Food gives me ‘hugs,’ ” Ms. S* said as her eyes lit up. Finally, after weeks of working together, she could articulate her complex relationship with food. She had been struggling to explain why she continued to eat when she was full or consumed foods she knew wouldn’t help her health.
Like millions of people struggling with their weight or the disease of obesity, Ms. S had tried multiple diets and programs but continued to return to unhelpful eating patterns. Ms. S was an emotional eater, and the pandemic only worsened her emotional eating. As a single professional forced to work from home during the pandemic, she became lonely. She went from working in a busy downtown office, training for half-marathons, and teaching live workout sessions to being alone daily. Her only “real” human interaction was when she ordered daily delivery meals of her favorite comfort foods. As a person with type 2 diabetes, she knew that her delivery habit was wrecking her health, but willpower wasn’t enough to make her stop.
Her psychologist referred her to our virtual integrative obesity practice to help her lose weight and find long-term solutions. Ms. S admitted that she knew what she was doing as an emotional eater. But like many emotional eaters, she didn’t know why or how to switch from emotional eating to eating based on her biological hunger signals. As a trained obesity expert and recovering emotional eater of 8 years, personally and professionally I can appreciate the challenges of emotional eating and how it can sabotage even the best weight loss plan. In this article, I will share facts and feelings that drive emotional eating. I aim to empower clinicians seeking to help patients with emotional eating.
Fact: Emotional eating isn’t all emotional
It’s important not to dismiss emotional eating as all emotion driven. Recall that hunger is hormonally regulated. There are two main hunger pathways: the homeostatic pathway and the hedonic pathway. The homeostatic pathway is our biological hunger pathway and is driven by the need for energy in calories. Conversely, hedonic eating is pleasure-driven and uses emotional stimuli to “bypass” the physical hunger/satisfaction signals.
Emotional eating falls under the hedonic pathway. As clinicians, the first step in helping a patient struggling with emotional eating is empathetically listening, then assessing for any physiologic causes.
Several factors can disrupt physiologic appetite regulation, such as sleep disturbances; high stress levels; and many medical conditions, including but not limited to obesity, diabetes, and polycystic ovarian syndrome. Such factors as insulin resistance and inflammation are a common link in these conditions. Both contribute to the pathophysiology of the changes in appetite and can influence other hormones that lead to reduced satisfaction after eating. Furthermore, mental health conditions may disrupt levels of neurotransmitters such as serotonin and dopamine, which can also cause appetite changes.
These settings of physiologically disrupted appetite can trigger hedonic eating. But the relationship is complex. For example, one way to research hedonic eating is by using the Power of Food Scale. Functional MRI studies show that people with higher Power of Food Scale readings have more brain activity in the visual cortex when they see highly palatable foods. While more studies are needed to better understand the clinical implications of this finding, it’s yet another indicator that “emotional” eating isn’t all emotional. It’s also physiologic.
Feelings: Patterns, personality, places, psychological factors
Physiology only explains part of emotional eating. Like Ms. S, emotional eaters have strong emotional connections to food and behavior patterns. Often, physiologic cues have been coupled with psychological habits.
For example, menses is a common physiologic trigger for stress-eating for many of my patients. Studies have shown that in addition to iron levels changing during menses, calcium, magnesium, and phosphorous levels also change. Emotionally, the discomfort of “that time of the month” can lead to solace in comfort foods such as chocolate in different forms. But this isn’t surprising, as cacao and its derivative, chocolate, are rich in iron and other minerals. The chocolate is actually addressing a physical and emotional need. It can be helpful to point out this association to your patients. Suggest choosing a lower-sugar form of chocolate, such as dark chocolate, or even trying cacao nibs, while addressing any emotions.
But physiologic conditions and patterns aren’t the only emotional eating triggers. Places and psychological conditions can also trigger emotional eating.
Places and people
Celebrations, vacations, proximity to certain restaurants, exposure to food marketing, and major life shifts can lead to increased hedonic eating. Helping patients recognize this connection opens the door to advance preparation for these situations.
Psychological conditions can be connected to emotional eating. It’s important to screen for mental health conditions and past traumas. For example, emotional eating could be a symptom of binge eating disorder, major depression, or generalized anxiety disorder. Childhood trauma is associated with disordered eating. The adverse childhood events quiz can be used clinically.
Emotional eating can lead to feelings of guilt, shame, and negative self-talk. It’s helpful to offer patients reassurance and encourage self-compassion. After all, it’s natural to eat. The goal isn’t to stop eating but to eat on the basis of physiologic needs.
Putting it together: Addressing the facts and feelings of emotional eating
1. Treat biological causes that impact physiologic hunger and trigger emotional eating.
2. Triggers: Address patterns, places/people, psychological events.
3. Transition to non-food rewards; the key to emotional eating is eating. While healthier substitutes can be a short-term solution for improving eating behaviors, ultimately, helping patients find non-food ways to address emotions is invaluable.
4. Stress management: Offer your patients ways to decrease stress levels through mindfulness and other techniques.
5. Professional support: Creating a multidisciplinary team is helpful, given the complexity of emotional eating. In addition to the primary care physician/clinician, other team members may include:
- Psychologist
- Psychiatrist
- coach and/or certified wellness coaches
- Obesity specialist
Back to Ms. S
Ms. S is doing well. We started her on a GLP-1 agonist to address her underlying insulin resistance. Together we’ve found creative ways to satisfy her loneliness, such as volunteering and teaching virtual workout classes. Her emotional eating has decreased by over 60%, and we continue to discover new strategies to address her emotional eating triggers.
Conclusion
Despite being common, the impact of emotional eating is often minimized. With no DSM-5 criteria or ICD-11 code, it’s easy to dismiss emotional eating clinically. However, emotional eating is common and associated with weight gain.
In light of the obesity epidemic, this significance can’t be overlooked. Thankfully we have groundbreaking medications to address the homeostatic hunger pathway and physiologic drivers of emotional eating, but they’re not a substitute for addressing the psychosocial components of emotional eating.
As clinicians, we can have a meaningful impact on our patients’ lives beyond writing a prescription.

Back to Ms. S
Ms. S is doing well. We started her on a GLP-1 agonist to address her underlying insulin resistance. Together we’ve found creative ways to satisfy her loneliness, such as volunteering and teaching virtual workout classes. Her emotional eating has decreased by over 60%, and we continue to discover new strategies to address her emotional eating triggers.
Conclusion
Despite being common, the impact of emotional eating is often minimized. With no DSM-5 criteria or ICD-11 code, it’s easy to dismiss emotional eating clinically. However, emotional eating is common and associated with weight gain.
In light of the obesity epidemic, this significance can’t be overlooked. Thankfully we have groundbreaking medications to address the homeostatic hunger pathway and physiologic drivers of emotional eating, but they’re not a substitute for addressing the psychosocial components of emotional eating.
As clinicians, we can have a meaningful impact on our patients’ lives beyond writing a prescription.

“Food gives me ‘hugs,’ ” Ms. S* said as her eyes lit up. Finally, after weeks of working together, she could articulate her complex relationship with food. She had been struggling to explain why she continued to eat when she was full or consumed foods she knew wouldn’t help her health.
Like millions of people struggling with their weight or the disease of obesity, Ms. S had tried multiple diets and programs but continued to return to unhelpful eating patterns. Ms. S was an emotional eater, and the pandemic only worsened her emotional eating. As a single professional forced to work from home during the pandemic, she became lonely. She went from working in a busy downtown office, training for half-marathons, and teaching live workout sessions to being alone daily. Her only “real” human interaction was when she ordered daily delivery meals of her favorite comfort foods. As a person with type 2 diabetes, she knew that her delivery habit was wrecking her health, but willpower wasn’t enough to make her stop.
Her psychologist referred her to our virtual integrative obesity practice to help her lose weight and find long-term solutions. Ms. S admitted that she knew what she was doing as an emotional eater. But like many emotional eaters, she didn’t know why or how to switch from emotional eating to eating based on her biological hunger signals. As a trained obesity expert and recovering emotional eater of 8 years, personally and professionally I can appreciate the challenges of emotional eating and how it can sabotage even the best weight loss plan. In this article, I will share facts and feelings that drive emotional eating. I aim to empower clinicians seeking to help patients with emotional eating.
Fact: Emotional eating isn’t all emotional
It’s important not to dismiss emotional eating as all emotion driven. Recall that hunger is hormonally regulated. There are two main hunger pathways: the homeostatic pathway and the hedonic pathway. The homeostatic pathway is our biological hunger pathway and is driven by the need for energy in calories. Conversely, hedonic eating is pleasure-driven and uses emotional stimuli to “bypass” the physical hunger/satisfaction signals.
Emotional eating falls under the hedonic pathway. As clinicians, the first step in helping a patient struggling with emotional eating is empathetically listening, then assessing for any physiologic causes.
Several factors can disrupt physiologic appetite regulation, such as sleep disturbances; high stress levels; and many medical conditions, including but not limited to obesity, diabetes, and polycystic ovarian syndrome. Such factors as insulin resistance and inflammation are a common link in these conditions. Both contribute to the pathophysiology of the changes in appetite and can influence other hormones that lead to reduced satisfaction after eating. Furthermore, mental health conditions may disrupt levels of neurotransmitters such as serotonin and dopamine, which can also cause appetite changes.
These settings of physiologically disrupted appetite can trigger hedonic eating. But the relationship is complex. For example, one way to research hedonic eating is by using the Power of Food Scale. Functional MRI studies show that people with higher Power of Food Scale readings have more brain activity in the visual cortex when they see highly palatable foods. While more studies are needed to better understand the clinical implications of this finding, it’s yet another indicator that “emotional” eating isn’t all emotional. It’s also physiologic.
Feelings: Patterns, personality, places, psychological factors
Physiology only explains part of emotional eating. Like Ms. S, emotional eaters have strong emotional connections to food and behavior patterns. Often, physiologic cues have been coupled with psychological habits.
For example, menses is a common physiologic trigger for stress-eating for many of my patients. Studies have shown that in addition to iron levels changing during menses, calcium, magnesium, and phosphorous levels also change. Emotionally, the discomfort of “that time of the month” can lead to solace in comfort foods such as chocolate in different forms. But this isn’t surprising, as cacao and its derivative, chocolate, are rich in iron and other minerals. The chocolate is actually addressing a physical and emotional need. It can be helpful to point out this association to your patients. Suggest choosing a lower-sugar form of chocolate, such as dark chocolate, or even trying cacao nibs, while addressing any emotions.
But physiologic conditions and patterns aren’t the only emotional eating triggers. Places and psychological conditions can also trigger emotional eating.
Places and people
Celebrations, vacations, proximity to certain restaurants, exposure to food marketing, and major life shifts can lead to increased hedonic eating. Helping patients recognize this connection opens the door to advance preparation for these situations.
Psychological conditions can be connected to emotional eating. It’s important to screen for mental health conditions and past traumas. For example, emotional eating could be a symptom of binge eating disorder, major depression, or generalized anxiety disorder. Childhood trauma is associated with disordered eating. The adverse childhood events quiz can be used clinically.
Emotional eating can lead to feelings of guilt, shame, and negative self-talk. It’s helpful to offer patients reassurance and encourage self-compassion. After all, it’s natural to eat. The goal isn’t to stop eating but to eat on the basis of physiologic needs.
Putting it together: Addressing the facts and feelings of emotional eating
1. Treat biological causes that impact physiologic hunger and trigger emotional eating.
2. Triggers: Address patterns, places/people, psychological events.
3. Transition to non-food rewards; the key to emotional eating is eating. While healthier substitutes can be a short-term solution for improving eating behaviors, ultimately, helping patients find non-food ways to address emotions is invaluable.
4. Stress management: Offer your patients ways to decrease stress levels through mindfulness and other techniques.
5. Professional support: Creating a multidisciplinary team is helpful, given the complexity of emotional eating. In addition to the primary care physician/clinician, other team members may include:
- Psychologist

Meat heavy diets may lead to ulcerative colitis flares
CHICAGO –
The data, which was presented on May 7 in Chicago at the annual Digestive Disease Week® meeting, is based on an analysis of data from the PREdiCCt study (Prognostic Effect of Environmental Factors in Crohn’s and Colitis) in which diets of patients with IBD were tracked over 2-3 months with 2-year follow-ups. While the study itself includes nearly 3,000 patients from the United Kingdom who are in clinical remission, this analysis included 497 patients with Crohn’s disease and 520 with ulcerative colitis.
The highest level of patient-reported meat consumption was associated with doubled risk for hard flares – defined as an increase in symptoms plus elevation in c-reactive protein (CRP) and fecal calprotection (FCAL) plus a change in IBD therapy – in patients with ulcerative colitis, said study author Charlie W Lees, PhD, FRCP(Ed), Western General Hospital and University of Edinburgh.
Investigators also evaluated the occurrence of soft flares, which was defined as a negative response to the question, “Do you think your disease has been well controlled in the past month or since you last logged on to the portal?”
After a median follow-up of 1,481.5 days, hard flares occurred at a rate of 5.6% per year, but it did not differ by IBD subtype. However, soft flares accumulated rapidly. Hard flares with baseline FCAL levels in the 50-250 mcg/g range, as well as FCAL levels above 250 mcg, were associated with flares.
The mean baseline total protein intake was 91.9 g per day of which 35.8 g came from animal sources. The hazard ratio for the highest vs. lowest quartile of meat intake in the ulcerative colitis group was 2.08. They found no associations between hard flares with intake of total dietary fiber, N-6 polyunsaturated acids, or ultraprocessed foods, which Dr. Lees found surprising.
“Perhaps most intriguingly, when we look at ultraprocessed food intake, no difference in Crohn’s disease, and no difference in ulcerative colitis,” Dr. Lees said.
The finding is in contradiction to a study reported at the Crohn’s & Colitis Congress this year that found additives in ultraprocessed foods appear to have deleterious effects on intestinal microbiota, while others may exert their influence through mechanisms, such as endoplasmic stress.
However, the new data are consistent with a previously reported association between meat consumption and ulcerative colitis development, and suggests that reducing meat consumption could help to reduce the risk of flare in patients with ulcerative colitis.
PREdiCCt is designed to examine dietary, environmental, genetic, and microbiotic factors that are associated with disease flares in patients with Crohn’s disease and ulcerative colitis. Investigators are evaluating potential contributions to disease flares from total animal protein intake, dietary fiber, N-6 polyunsaturated fatty acids, dietary emulsifiers, and ultraprocessed foods, and total bacterial gene count in stool samples. They aim to examine data from 2,500 microbiome samples currently being sequenced at the Wellcome Sanger Institute in Hinxton, England, to determine whether the association between meat and ulcerative colitis flares could be related, as they hypothesize, to diet-induced alterations in the gut microbiome.
The research is preliminary with many unanswered questions, said Russell D. Cohen, MD, director of the inflammatory bowel disease center at the University of Chicago.
“I think he still has to evaluate a lot of the data that he has already collected because, are you talking about meat? Are you talking about poultry? Are you talking about fish? It is interesting, but it still needs to be evaluated further before we make any conclusive decisions,” he said. Dr. Cohen was not involved in the research.
He said the presumed effect of meat consumption on disease exacerbation appeared to take years, “which is a little surprising. If you really thought that IBD was due to something in diet, you would see the response right away, so it doesn’t follow timewise. Why does it takes 5 years? It should be within 5 weeks or 5 days.”
Dr. Lees disclosed relationships with Abbvie, Takeda, Pfizer, Galapagos, and BDD Pharma, among others.
