Atezolizumab is associated with enhanced response in triple-negative breast cancer
based on final data from a randomized trial.
The IMpassion031 trial showed significant improvement in pathological complete response (pCR) with the addition of atezolizumab to chemotherapy, as well as an acceptable safety profile, said Carlos H. Barrios, MD, of the Latin American Cooperative Oncology Group, Oncoclinicas, in Porto Allegre, Brazil, at the European Society for Medical Oncology (ESMO) Breast Cancer annual congress. Those findings were published in the Lancet in 2020.
Dr. Barrios reported data from a final analysis of the IMpassion031 trial, with data on event-free survival (EFS), disease-free survival (DFS) and overall survival (OS) in the intent-to-treat (ITT) and PD-L1–positive populations.
In the study, patients with early triple-negative breast cancer (eTNBC) and a primary tumor greater than 2 cm were randomized to 840 mg of atezolizumab once every 2 weeks plus a neoadjuvant chemotherapy regimen of nab-paclitaxel 125 mg/m2 once weekly for 12 weeks, followed by doxorubicin 60 mg/m2 plus cyclophosphamide 600 mg/m2 once every 2 weeks for 8 weeks. A total of 333 patients were randomized (165 atezolizumab and 168 placebo). Patients were stratified by stage II versus stage III, and by status of PD-L1, a protein that can predict treatment response (PD-L1 less than 1% vs. 1% or higher).
The primary endpoints (previously reported) were pathological complete response (pCR) in the ITT and PD-L1 populations. After a median follow-up of 39 months, the pCR was 58% in patients treated with atezolizumab versus 41% in those treated with neoadjuvant chemotherapy alone (P = .0044) in the ITT population, Dr. Barrios said. The added benefit from atezolizumab occurred regardless of the status of PD-L1.
Dr. Barrios reported the secondary outcomes of EFS, DFS, and OS in the intent-to-treat and PD-L1–positive populations. “This is a descriptive analysis, with no statistical comparison,” he emphasized.
The 2-year data on EFS, DFS, and OS consistently favored atezolizumab across key clinical subgroups, Dr. Barrios said. In the ITT population, 2-year EFS, DFS, and OS was 85%, 87%, and 95%, respectively, in the atezolizumab group and 80%, 83%, and 90%, respectively, in the placebo group. The results were similar, irrespective of PD-L1 status.
In the PD-L1–positive population, 2-year EFS, DFS, and OS was 89%, 91%, and 95%, respectively, in atezolizumab patients and 80%, 87%, and 91% in placebo patients.
Among patients without pCR at the time of surgery, 14 of 70 patients (20%) in the atezolizumab group and 33 of 99 patients (33%) in the placebo group received additional adjuvant systemic therapy. The most common adjunctive therapy was capecitabine.
As for safety, no new safety signals or treatment-related deaths were observed in the study. Overall, 70% of atezolizumab patients and 62% of placebo patients experienced grade 3 or 4 adverse events (AEs); 59% and 54% of which were treatment related. A total of 1% of patients in each group experienced grade 5 AEs. A total of 25% of atezolizumab patients and 20% of placebo patients experienced AEs leading to treatment discontinuation.
In a further exploratory analysis, pCR was highly predictive of long-term outcomes. Exploratory analysis of circulating tumor DNA (ctDNA) showed clearance in 89% of atezolizumab patients and 86% of placebo patients by the time of surgery.
Looking at the relationship between ctDNA, DFS, and OS, positive ctDNA was associated with a worse prognosis following surgery. As demonstrated in previous studies, pCR patients with negative ctDNA had the best DFS and OS. “In non-pCR patients with positive ctDNA, a numerical trend suggests improved overall survival with atezolizumab,” although the caveat is the very small numbers, Dr. Barrios said.
More research is needed, but in the final analysis, the significant pCR benefit seen with the addition of atezolizumab to chemotherapy for eTNBC translated into numerically improved EFS, DFS and OS, said Dr. Barrios. Additionally, “we should further analyze ctDNA to help select patients for further therapy.”
In a question-and-answer session, Dr. Barrios was asked how the results compared with other studies.
“We should not overinterpret the results,” he said. However, “what the IMpassion031 study shows is consistency; the results are aligned with previous studies addressing the same question of introducing immunotherapy,” in the patient population. Although the numbers in the IMpassion031 study did not reach statistical significance, it is important to recognize that they reflect previous research.
“In my opinion, looking at the whole field, immunotherapy is something we need to consider as part of the treatment of these patients,” said Dr. Barrios. However, more research is needed to better identify which patients do and do not need chemotherapy.
Phase 2 data show increased response with added atezolizumab for PD-L1–negative patients
In a second study known as ABSCG-52/ATHENE, researchers evaluated neoadjuvant atezolizumab in combination with dual HER2 blockade plus epirubicin for the treatment of patients with early HER2-positive breast cancer.
For most of these patients, the current standard of care is neoadjuvant dual HER2 blockade with trastuzumab (T) and pertuzumab (P) plus poly-chemotherapy, said Gabriel Rinnerthaler, MD, of the Salzburg (Austria) Cancer Research Institute, said in his presentation at the meeting. However, de-escalation of chemotherapy has been a major focus of research in recent years, and more research is needed on a combination of anthracyclines, such as epirubicin and idarubicin, and immune-checkpoint modulators.
In the phase 2 study, the researchers randomized patients with previously untreated, histologically confirmed HER2-positive early breast cancer (defined as a clinical prognostic stage cT1c–4a-d, N0-3, M0) in a 1:1 ratio to two 3-weekly cycles of a chemotherapy-free induction phase (part 1) with TP plus 1,200 mg atezolizumab (TP-A) or TP alone.
“We hypothesized that the additive effect of immune checkpoint inhibitors plus anti-HER2 therapy and chemotherapy would not be linear,” he said.
At the end of this period, all patients underwent four cycles of TP-A in combination with epirubicin (part 2). The primary endpoint was pCR (defined as absence of invasive cancer in the breast and axillary nodes, or ypT0/Tis ypN0) in the overall study population, and a pCR of 40% was considered a positive result.
A total of 29 patients were randomized to TP-A and 29 to TP alone in nine treatment centers in Austria. The study population ranged from 33 to 82 years, with a median age of 57 years. Most patients (72.4%) had hormone receptor (HR)–positive tumors; a total of 45 patients had stage IIA cancer, and 13 had stage IIB.
The primary endpoint of pCR occurred in 35 patients overall (60.3%). In a univariate analysis, the response rates were lower in HR-positive patients, in premenopausal patients, and in histologies other than NST (invasive carcinoma of no special type), Dr. Rinnerthaler said, but none of the differences were statistically significant, likely because of the small numbers in each group.
In an exploratory analysis of the ITT population with available PD-L1 data, the pCR was 69.2% for PD-L1–negative patients and 55.2% for PD-L1–positive patients.
“We observed the highest pCR rates in PD-L1–negative patients treated in the TP-A group and the lowest in PD-L1–positive patients treated with TP alone,” Dr. Rinnerthaler said.
No new safety concerns were observed during the study, Dr. Rinnerthaler noted. AEs of grade 3 or higher occurred in 17 patients (29.3%), including 9 in the TP-A group and 8 in the TP group. The most common AEs in both groups were nausea, diarrhea, and fatigue. No AEs of special interest of grade 3 or higher (defined as immune-related AEs, cardiac disorders, or infusion-related reactions) were observed.
The study findings were limited by the small sample size, but the resulting pCR rate of 60.3% was higher than the predefined threshold of 40% and supports additional research, said Dr. Rinnerthaler.
“For HER2-positive early breast cancer, a neoadjuvant chemotherapy de-escalation immunotherapy regimen with trastuzumab, pertuzumab, atezolizumab, and epirubicin is highly effective and safe and merits further investigation,” he concluded.
During a question-and-answer session, Dr. Rinnerthaler was asked why pCR increased in PD-L1 negative patients.
Previous data have shown that PD-L1 is up-regulated in certain tumors, and may serve as a surrogate for sensitivity, he said. In previous studies the additional effect of atezolizumab was seen in a PD-L1–negative group.
Dr. Rinnerthaler said he hopes to clarify this question when his research team reviews biopsy data from baseline and after the induction phase.
Defining response is key to de-escalation
In the IMpassion031 trial, “what we saw is a tendency to better outcomes for those patients who received atezolizumab,” said Matteo Lambertini, MD, of the University of Genova (Italy), who served as discussant for the two studies. The IMpassion031 study raises the question of where we are in the use of immuno-oncology for eTNBC. The study is now one of five neoadjuvant trials in this population.
Dr. Lambertini cited the KEYNOTE-522 study, which showed significant results in EFS. However, sample sizes and statistical design were different between these studies. “I think we need large studies of data in the adjuvant and postneoadjuvant setting for patients with triple-negative breast cancer.”
Postneoadjuvant considerations from the IMpassion031 trial showed good outcomes with no additional benefit of an immune checkpoint inhibitors.
For those patients with a pCR, it is definitely time to de-escalate treatment,” he said. In patients without pCR, escalation is needed, but an improved definition of pCR is also needed.
With regard to the ATHENE study, “it may be considered a positive study because the threshold of 40% was reached,” he said. The question is what is the optimum chemotherapy backbone. There appears to be no added benefit to adding an immune checkpoint inhibitor.
There are needs for defining the role of immunotherapy in HER2-positive breast cancer and more biomarker research to inform patient selection and study design, he said.
Finally, “I am not sure that the addition of an immune checkpoint inhibitor can be considered a de-escalation,” he noted.

There are needs for defining the role of immunotherapy in HER2-positive breast cancer and more biomarker research to inform patient selection and study design, he said.
Finally, “I am not sure that the addition of an immune checkpoint inhibitor can be considered a de-escalation,” he noted.

FROM ESMO BREAST CANCER 2023
Patritumab deruxtecan shows promise for breast cancer patients
according to data presented from Abstract 1240 at the European Society for Medical Oncology (ESMO) Breast Cancer annual congress.
Patritumab deruxtecan (HER3-DXd) has previously demonstrated an acceptable safety profile and antitumor activity in phase I studies involving heavily pretreated patients with metastatic breast cancer and various levels of HER3 protein expression, said Mafalda Oliveira, MD, of the Vall d’Hebron University Hospital and Vall d’Hebron Institute of Oncology in Barcelona.
Antibody-drug conjugates (ADCs) are a combination of a monoclonal antibody chemically linked to a drug, as defined by the National Cancer Institute. ADCs work by binding to receptors or proteins and selectively delivering cytotoxic drugs to the site of a tumor.
Dr. Oliveira presented results from part B the of SOLTI TOT-HER3 trial, a window-of-opportunity trial that evaluated the effect of a single dose of HER3-Dxd in patients with treatment-naive HR+/HER2– early breast cancer.
In such trials, patients receive one or more new compounds between the time of cancer diagnosis and standard treatment. Biological and clinical activity from part A of the SOLTI TOT-HER3 trial were presented at last year’s ESMO Breast Cancer Congress, Dr. Oliveira said.
In the current study, Dr. Oliveira and colleagues recruited 37 women with HR+/HER2– early breast cancer, including 20 who were hormone receptor–positive and 17 who had triple negative breast cancer (TNBC). The age of the participants ranged from 30 to 81 years, with a median age of 51 years; 54% were premenopausal. The mean tumor size was 21 mm, with a range of 10-81 mm.
Distinct from part A of the SOLTI TOT-HER3 trial, part B included a subset of patients with TNBC to assess preliminary efficacy in this subtype, Dr. Oliveira noted.
All patients in part B received a single dose of 5.6 mg/kg of HER3-DXd. The primary outcome was the variation in the tumor cellularity and tumor-infiltrating lymphocyte (CelTIL) score at baseline and after 21 days via breast ultrasound.
At day 21, the total CelTIL score increased by a significant mean difference of 9.4 points after a single dose; the mean differences for TNBC and HR+/HER2– patients, were 17.9 points and 2.2 points, respectively, Dr. Oliveira said. The overall response rate was 32% (35% in TNBC patients and 30% in HR+/HER2– patients) and was significantly associated with the absolute change in CelTIL (area under the curve = 0.693; P = .049).
In a subtype analysis, a statistically significant change in CelTIL was observed between paired samples overall (P = .046) and in TNBC (P = .016), but not in HR+ (P = .793).
Baseline levels of ERBB3 (also known as human epidermal growth factor receptor type 3, or HER3) were not associated with changes in CelTIL or in overall response rate.
HER3-DXd induced high expression of immune-related genes (such as PD1, CD8, and CD19), and suppressed proliferation-related genes, she said.
A total of 31 patients (84%) reported any adverse events. Of these, the most common were nausea, fatigue, alopecia, diarrhea, constipation, and vomiting, and one patient experienced grade 3 treatment-related nausea. No interstitial lung disease events were reported during the study, and the incidence of hematological and hepatic toxicity was lower with the lower dose in part B, compared with the 6.5 mg/kg dose used in part A, Dr. Oliveira noted.
To further validate the findings of the current study and assess the activity of HER3-DXd in early breast cancer, Dr. Oliveira and colleagues are conducting a neoadjuvant phase II trial known as SOLTI-2103 VALENTINE. In this study, they are testing six cycles of HER3-DXd at a 5.6 mg/kg dose in HR+/HER2– breast cancer patients, she said.
During a question-and-answer session, Dr. Oliveira was asked whether CelTIL is the best endpoint for assessing HER3-DXd. Finding the best endpoint is always a challenge when conducting window-of-opportunity trials, she said. The CelTIL score has been correlated with pathologic complete response (pCR), as well as with disease-free survival and overall survival, she added.
ICARUS-BREAST01
In a presentation of Abstract 1890 during the same session, Barbari Pistilli, MD, of Gustave Roussy Cancer Center, Villejuif, France, shared data from a phase II study known as ICARUS-BREAST.
The study population included women with unresectable locally advanced breast cancer (ABC) who had undergone a median of two previous systemic therapies. In the current study, the patients underwent a median of eight cycles of HER3-DXd. The dosage was 5.6 mg/kg every 3 weeks until disease progression or unacceptable toxicity.
The primary outcome was overall response and disease progression after 3 months. Dr. Pistilli, who is also a coauthor of the research, provided data from 56 evaluable patients.
After 3 months, 16 patients (28.6%) showed a partial response, 30 patients showed stable disease (54%), and 10 (18%) showed disease progression. “No patients had a complete response,” Dr. Pistilli noted.
As for the safety profile, all patients reported at least one treatment-emergent event of any grade, but less than half (48.2%) were grade 3 or higher, and 12.5% led to treatment discontinuation. Fatigue and nausea were the most frequently reported adverse events overall, and occurred in 89.3% and 76.8% of patients, respectively. All grade and grade 3 or higher neutropenia occurred in four patients and six patients, respectively; all grade and grade 3 or higher thrombocytopenia occurred in four patients and two patients, respectively, Dr. Pistilli said.
Data on circulating tumor cells (CTCs) were available for 31 patients, and the researchers reviewed CTC counts after the first HER3-DXd cycle.
“We found that the median number of CTCs decreased by one to two cell cycles of HER3-DXd,” said Dr. Pistilli. She and her coauthors found no substantial impact of the treatment on HER3 negative CTC counts, and “more importantly, no increase of HER3 negative CTC counts at disease progression,” Dr. Pistilli continued.
In addition, patients with higher HER+ CTC counts at baseline or a greater decrease in HER3+ CTC counts after one cycle of HER3-DXd were more likely to have an early treatment response, but this association was not statistically significant.
Looking ahead, further analysis will be performed to evaluate the association between HER3+ CTC counts and dynamics and the main outcomes of overall response rate and progression-free survival to determine the potential of HER3+ CTC counts to identify patients who can benefit from HER3-DXd, said Dr. Pistilli. The ICARUS-BREAST01 study is ongoing, and further efficacy and biomarker analysis will be presented, she added.
In the question-and-answer session, Dr. Pistilli was asked why she chose CTC as a measure.
Dr. Pistilli responded that she and her coauthors wanted to understand whether CTC could serve as a biomarker to help in patient selection.
Also, when asked about which genes might be upregulated and downregulated in responders vs. nonresponders, she noted that some genes related to DNA repair were involved in patients who were responders, but more research is needed.
Early results merit further exploration
Although patritumab deruxtecan is early in development, “there is a clear signal to expand,” based on preliminary research, said Rebecca A. Dent, MD, who served as discussant for the two studies.
“There is no clear role for a specific subtype in both protein and gene expression,” noted Dr. Dent, who is a professor at Duke NUS Medical School, a collaboration between Duke University, Durham, N.C., and the National University of Singapore.
In the SOLTI TOT-HER3 trial, the small numbers make teasing out correlations a challenge, said Dr. Dent. However, changes were observed after just one cycle of the drug, and the upregulation of immune signature genes was reassuring, she said.
“A single dose of HER3-DXd induced an overall response of approximately 30% independently of hormone receptor status,” she emphasized, and the lower incidence of hematological and hepatic toxicity with the lower dose is good news as well. The findings were limited by the small sample size, but the results support moving forward with clinical development of HER3-DXd, she said.
The ICARUS-BREAST01 study researchers tried to show whether they could identify potential markers of early treatment response, and they examined CTCs and gene alterations, said Dr. Dent. “I think it is reassuring that despite these patients being heavily pretreated, HER-DXd seems to be active regardless of most frequent breast cancer genomic alterations,” she noted. Remaining questions include the need for more data on primary resistance.
“We are able to get these patients to respond, but what makes patients resistant to ADCs is just as important,” she said. “We see exciting data across all these subtypes,”
In Dr. Dent’s opinion, future research should focus on triple negative breast cancer, an opinion supported by the stronger response in this subset of patients in the SOLTI TOT-HER3 trial. “I think you need to bring triple negative to the table,” she said.
The SOLTI TOT-HER3 study was funded by Daiichi Sankyo. Dr. Oliveira disclosed relationships with companies including AstraZeneca, Ayala Pharmaceuticals, Boehringer-Ingelheim, Genentech, Gilead, GSK, Novartis, Roche, Seagen, Zenith Epigenetics, Daiichi Sankyo, iTEOS, MSD, Pierre-Fabre, Relay Therapeutics, and Eisai.

FROM ESMO BREAST CANCER 2023
FDA approves new drug to manage menopausal hot flashes
The Food and Drug Administration has approved the oral medication fezolinetant (Veozah) for the treatment of moderate to severe hot flashes in menopausal women, according to an FDA statement. The approved dose is 45 mg once daily.
Fezolinetant, a neurokinin 3 (NK3) receptor antagonist, is the first drug of its kind to earn FDA approval for the vasomotor symptoms associated with menopause, according to the statement. The drug works by binding to the NK3 receptor, which plays a role in regulating body temperature, and blocking its activity. Fezolinetant is not a hormone, and can be taken by women for whom hormones are contraindicated, such as those with a history of vaginal bleeding, stroke, heart attack, blood clots, or liver disease, the FDA stated.
The approval was based on data from the SKYLIGHT 2 trial, results of which were presented at the annual meeting of the Endocrine Society, reported by this news organization, and published in the Journal of Clinical Endocrinology and Metabolism.
In the two-phase trial, women were randomized to 30 mg or 45 mg of fezolinetant or a placebo. After 12 weeks, women in placebo groups were rerandomized to fezolinetant for a 40-week safety study.
The study population included women aged 40-65 years, with an average minimum of seven moderate-to-severe hot flashes per day. The study included 120 sites in North America and Europe.
At 12 weeks, both placebo and fezolinetant patients experienced reductions in moderate to severe vasomotor symptoms of approximately 60%, as well as a significant decrease in vasomotor symptom severity.
The FDA statement noted that patients should undergo baseline blood work before starting fezolinetant to test for liver infection or damage, and the prescribing information includes a warning for liver injury; blood work should be repeated at 3, 6, and 9 months after starting the medication, according to the FDA and a press release from the manufacturer Astellas.
The most common side effects associated with fezolinetant include abdominal pain, diarrhea, insomnia, back pain, hot flashes, and elevated liver values, according to the FDA statement. The FDA granted Astellas Pharma’s application a Priority Review designation. Astellas has priced the drug at $550 for a 30-day supply, significantly higher than the Institute for Clinical and Economic Review’s previously recommended range of $2,000 to $2,500 per year.
Full prescribing information is available here.

The approval was based on data from the SKYLIGHT 2 trial, results of which were presented at the annual meeting of the Endocrine Society, reported by this news organization, and published in the Journal of Clinical Endocrinology and Metabolism.
In the two-phase trial, women were randomized to 30 mg or 45 mg of fezolinetant or a placebo. After 12 weeks, women in placebo groups were rerandomized to fezolinetant for a 40-week safety study.
The study population included women aged 40-65 years, with an average minimum of seven moderate-to-severe hot flashes per day. The study included 120 sites in North America and Europe.
At 12 weeks, both placebo and fezolinetant patients experienced reductions in moderate to severe vasomotor symptoms of approximately 60%, as well as a significant decrease in vasomotor symptom severity.
The FDA statement noted that patients should undergo baseline blood work before starting fezolinetant to test for liver infection or damage, and the prescribing information includes a warning for liver injury; blood work should be repeated at 3, 6, and 9 months after starting the medication, according to the FDA and a press release from the manufacturer Astellas.
The most common side effects associated with fezolinetant include abdominal pain, diarrhea, insomnia, back pain, hot flashes, and elevated liver values, according to the FDA statement. The FDA granted Astellas Pharma’s application a Priority Review designation. Astellas has priced the drug at $550 for a 30-day supply, significantly higher than the Institute for Clinical and Economic Review’s previously recommended range of $2,000 to $2,500 per year.

The Food and Drug Administration has approved the oral medication fezolinetant (Veozah) for the treatment of moderate to severe hot flashes in menopausal women, according to an FDA statement. The approved dose is 45 mg once daily.
Fezolinetant, a neurokinin 3 (NK3) receptor antagonist, is the first drug of its kind to earn FDA approval for the vasomotor symptoms associated with menopause, according to the statement. The drug works by binding to the NK3 receptor, which plays a role in regulating body temperature, and blocking its activity. Fezolinetant is not a hormone, and can be taken by women for whom hormones are contraindicated, such as those with a history of vaginal bleeding, stroke, heart attack, blood clots, or liver disease, the FDA stated.

BMI has greater impact on survival in younger breast cancer patients
new data suggest.
Obesity is a well-known risk factor for breast cancer in postmenopausal women and has been associated with adverse prognosis, said Senna W.M. Lammers, MD, of Maastricht (the Netherlands) University during a presentation at the European Society for Medical Oncology (ESMO) Breast Cancer annual congress. In addition, some studies suggest that patients with higher body mass index (BMI) experience reduced benefits from endocrine therapy, she said.
Dr. Lammers and colleagues conducted a study to determine the prognostic and predictive effect of BMI on disease-free survival in postmenopausal women with hormone receptor–positive (HR+) breast cancer who were treated with extended endocrine therapy.
The study population included participants in the randomized, phase III DATA trial, which evaluated the use of 6 years vs. 3 years of anastrozole in postmenopausal women with HR+ breast cancer who were disease-free after 2-3 years of adjuvant tamoxifen therapy.
Patients were categorized based on BMI as having normal weight (18.5-24.9 kg/m2), overweight (25-29.9 kg/m2), or obese (30 kg/m2 or higher). The primary outcome was disease-free survival (DFS); the median follow-up period was 13.1 years.
DFS for patients with normal weight, overweight, and obesity was 66.2%, 59.5%, and 52.4%, with a P value of less than .001 for the trend, Dr. Lammers said. “These results were confirmed in multivariable analysis,” she said. Overall, patients with overweight and obesity had a worse DFS when compared with patients with normal weight (hazard ratio, 1.16; P = .10, for patients with overweight and HR, 1.26; P = .03 for patients with obesity).
“Next, we aimed to determine whether the prognostic effect of BMI differed by age,” Dr. Lammers said.
In women younger than 60 years, overweight and obesity were significantly associated with worse DFS (HR, 1.29; P = .05 and HR 1.83, P less than .001, respectively). However, this effect was not observed in women aged 60 years and older.
The researchers also examined the treatment effect of extended anastrozole on adapted DFS by weight, and found no significant differences among patients with normal weight, overweight, and obesity (HR, 1.00; HR, 0.74; and HR, 0.97, respectively), said Dr. Lammers.
In the question and answer session, Dr. Lammers was asked about possible explanations for the difference in DFS by age. Potential explanations include possible survival bias “as only the healthier [patients with obesity] survive to old age,” she said. Other potential explanations are biological, such as the potentially higher levels of bone density in older [patients with obesity], she said.
When asked about additional clinical implications, Dr. Lammers emphasized the importance of maintaining a healthy BMI for breast cancer patients of all ages. Other research areas might involve the use of lifestyle interventions, although these are challenging to implement, she noted.
Data draw attention to quality of life and lifestyle factors
The need to “look at drug development with new eyes” is particularly important when reviewing patient-reported outcomes, said Otto Metzger, MD, of the Dana Farber Cancer Institute, Boston, who served as the discussant for the session.
Dr. Metzger brought up the association between age and the effect of BMI on DFS, specifically.
Based on data from multiple studies and meta-analyses, “I do believe that obesity does play a role in prognosis,” he said, but the question is how long will researchers continue to simply record data without acting to add lifestyle interventions while also trying to develop new drugs, he said. Although convincing patients to make lifestyle changes remains a challenge, patients are often more motivated to make such changes after a cancer diagnosis, Dr. Metzger noted.
“I am a firm believer in the use of digital therapeutics in the context of clinical trials,” said Dr. Metzger. Digital technology offers great potential to educate patients on [adverse effects] and also to improve treatment adherence and quality of life, he concluded.
The study was supported by AstraZeneca, and Dr. Lammers disclosed financial relationships with AstraZeneca and Eli Lilly. Dr. Metzger disclosed receiving research funding to his institution from Pfizer, Genentech/Roche, and Sanofi, and serving as an adviser/consultant to AstraZeneca, Merck, Oncoclinicas, Resilience, and Roche.

Early gestational diabetes treatment may improve neonatal outcomes
Screening and treatment for gestational diabetes are currently recommended at 24-28 weeks’ gestation, with earlier testing recommended for women at increased risk, but the potential benefits of earlier intervention remain debatable, wrote David Simmons, MD, of Western Sydney University, Campbelltown, Australia, and colleagues.
“Until now, there has been complete equipoise over whether to treat hyperglycemia below that of overt diabetes early in pregnancy,” Dr. Simmons said in an interview. The conflicting questions: “Would early treatment reduce the excess deposition of fat on the baby with all of its sequelae; but would early treatment reduce fuel supply to some babies at a critical time and lead to SGA [small for gestational age]?” Dr. Simmons noted.
In a study published in the New England Journal of Medicine, Dr. Simmons and colleagues randomized 406 women aged 18 years and older with singleton pregnancies to immediate treatment for gestational diabetes. Another 396 women were randomized to a control group for deferred treatment or no treatment, based on results of an oral glucose tolerance test at 24-28 weeks’ gestation. All participants had at least one risk factor for hyperglycemia, and met the World Health Organization criteria for gestational diabetes. Women with preexisting diabetes or contraindicating comorbid medical conditions were excluded.
The study had three primary outcomes. The first was a composite of neonatal outcomes including birth before 37 weeks’ gestation, birth weight of 4,500 g or higher, birth trauma, neonatal respiratory distress, phototherapy, stillbirth or neonatal death, or shoulder dystocia.
The final sample included 748 women for adverse neonatal outcomes, 750 for pregnancy-related hypertension, and 492 for neonatal lean body mass. The mean age of the participants was 32 years; approximately one-third were white European and another third were South Asian. Overall baseline demographics were similar between the groups, and the initial oral glucose tolerance tests were performed at a mean of 15.6 weeks’ gestation.
Overall, 24.9% of women in the early treatment group experienced an adverse neonatal event vs. 30.5% of controls, for an adjusted risk difference of –5.6% and adjusted relative risk of 0.82.
Notably, in an exploratory subgroup analysis, respiratory distress occurred in 9.8% of infants born to women in the immediate treatment group vs. 17.0% of infants in the control group. “Neonatal respiratory distress was the main driver of the between-group difference observed for the first primary outcome,” the researchers wrote. A prespecified subgroup analysis suggested that the impact of an earlier intervention on adverse neonatal outcomes might be greater among women with a higher glycemic value and those whose oral glucose tolerance tests occurred at less than 14 weeks’ gestation, they noted. Stillbirths or neonatal deaths were similar and infrequent in both groups.
Pregnancy-related hypertension occurred in 10.6% of the immediate-treatment group and 9.9% of the controls group (adjusted risk difference, 0.7%). For the third outcome, the mean neonatal lean body mass was 2.86 g in the immediate-treatment group and 2.91 g for the controls (adjusted mean difference, −0.04 g).
No differences in serious adverse events related to either screening or treatment were noted between the groups.
Impact on neonatal outcomes merits further study
Dr. Simmons said that he was surprised by the study findings. “We thought if there was an effect, it would be small, but it isn’t,” he told this publication.
“If you combine the severe adverse outcomes, the perineal trauma and the reduction in days in NICU/special care unit, this is a significant impact on morbidity and likely on cost,” and researchers are currently examining data for cost-effectiveness, he said.
“We did not expect the likely large impact on reducing respiratory distress and perineal trauma,” he noted. “These findings have not been previously reported, perhaps because they were not looked for.” By contrast, “we thought here might be reductions in lower gestational age and cesarean delivery, but there was not,” he added.
The findings were limited by several factors including the nonstandardized approach to gestational diabetes treatment and the use of third-trimester treatment targets that had not been tested in earlier trimesters, the researchers noted. Other limitations included the focus on women already at high risk for hyperglycemia; therefore, the results might not generalize to women not at risk, they wrote.
The current study represents a beginning of answers, with data suggesting that early treatment for gestational diabetes reduces severe adverse pregnancy outcomes, days in NICU/special care unit, and perineal trauma, likely from the first trimester, said Dr. Simmons. However, the findings must be interpreted with caution, as criteria that are too low “might lead to more small babies,” he said. “We look forward to working with others to translate these findings into practice,” he added.
Much more research is needed to answer the many questions prompted by the current study, including who did and did not have complications, Dr. Simmons told this publication. Other studies are needed to collect data on cost-effectiveness, as well as consumer views, especially “different perspectives from different parts of the globe,” he said. Although there is not enough evidence yet to draw conclusions about the role of continuous glucose monitoring (CGM) in managing gestational diabetes, many studies are underway; “we look forward to the results,” of these studies, Dr. Simmons added.
Findings support early screening
Gestational diabetes is one of the most common medical complications of pregnancy, and accounts for more than 80% of diabetes-related diagnoses in pregnancy, said Emily Fay, MD, a maternal-fetal medicine specialist at the University of Washington, Seattle, in an interview.
“Previous studies have found that women with gestational diabetes are at higher risk in their pregnancy, including higher chance of developing preeclampsia, higher chance of cesarean delivery, and higher risks for their baby, including risk of shoulder dystocia, birth trauma, and jaundice, and higher birth weights,” she said. “Fortunately, studies have also shown that treatment of gestational diabetes helps lower these risks,” she noted. Currently, patients undergo routine screening for gestational diabetes between 24 and 28 weeks of pregnancy, but some who have risk factors for gestational diabetes may have screening in the early part of pregnancy, said Dr. Fay.
The current findings were not surprising overall, said Dr. Fay, who was not involved in the study. “The study authors looked at a variety of outcomes including neonatal adverse outcomes, neonatal body weight, and pregnancy-related hypertension,” she said.
The researchers found that patients treated early had a lower rate of adverse neonatal outcomes, which was to be expected, Dr. Fay said. “They did not find a difference in neonatal body weight; this also was not surprising, as the women who were not in the early treatment group still received treatment at the time of diagnosis later in pregnancy, which likely helped normalize the weights,” she explained.
“My takeaway from this study is that we should continue to screen patients with risk factors for gestational diabetes early in pregnancy and treat them at the time of diagnosis,” Dr. Fay told this publication. However, barriers that may exist to early treatment involve access to care, including being able to see a provider early in pregnancy, she said. “The treatment for gestational diabetes includes dietary education with diet changes and checking blood sugars frequently. Access to nutrition education can be limited and access to healthy foods can be expensive and difficult to obtain,” she noted. “Checking blood sugars throughout the day can also be difficult for those who are busy or working and who may not have the ability to take time to do this,” she said. However, “these barriers may be overcome by health care reform that improves patient access to and coverage of pregnancy care, improved access and affordability of healthy foods, and employer flexibility to allow the time and space to check blood sugars if needed,” she added.
Looking ahead, the use of continuous glucose monitors in pregnancy is an expanding area of research, said Dr. Fay. “Patients can quickly view their blood sugar without the use of finger sticks, which may help overcome some of the barriers patients may have with using finger sticks,” she noted. “Continuous glucose monitors have been used for those with type 1 and type 2 diabetes with success, and we need to better understand if these can also be helpful in gestational diabetes,” she said. Dr. Fay and colleagues at the University of Washington are currently conducting an ongoing study to explore the use of CGM in gestational diabetes.
The study was supported by the National Health and Medical Research Council, the Region Örebro Research Committee, the Medical Scientific Fund of the Mayor of Vienna, the South Western Sydney Local Health District Academic Unit, and a Western Sydney University Ainsworth Trust Grant. The researchers had no financial conflicts to disclose. Dr. Fay had no relevant financial conflicts to disclose.

Women with preexisting diabetes or contraindicating comorbid medical conditions were excluded.
The study had three primary outcomes. The first was a composite of neonatal outcomes including birth before 37 weeks’ gestation, birth weight of 4,500 g or higher, birth trauma, neonatal respiratory distress, phototherapy, stillbirth or neonatal death, or shoulder dystocia.
The final sample included 748 women for adverse neonatal outcomes, 750 for pregnancy-related hypertension, and 492 for neonatal lean body mass. The mean age of the participants was 32 years; approximately one-third were white European and another third were South Asian. Overall baseline demographics were similar between the groups, and the initial oral glucose tolerance tests were performed at a mean of 15.6 weeks’ gestation.
Overall, 24.9% of women in the early treatment group experienced an adverse neonatal event vs. 30.5% of controls, for an adjusted risk difference of –5.6% and adjusted relative risk of 0.82.
Notably, in an exploratory subgroup analysis, respiratory distress occurred in 9.8% of infants born to women in the immediate treatment group vs. 17.0% of infants in the control group. “Neonatal respiratory distress was the main driver of the between-group difference observed for the first primary outcome,” the researchers wrote. A prespecified subgroup analysis suggested that the impact of an earlier intervention on adverse neonatal outcomes might be greater among women with a higher glycemic value and those whose oral glucose tolerance tests occurred at less than 14 weeks’ gestation, they noted. Stillbirths or neonatal deaths were similar and infrequent in both groups.
Pregnancy-related hypertension occurred in 10.6% of the immediate-treatment group and 9.9% of the controls group (adjusted risk difference, 0.7%). For the third outcome, the mean neonatal lean body mass was 2.86 g in the immediate-treatment group and 2.91 g for the controls (adjusted mean difference, −0.04 g).
No differences in serious adverse events related to either screening or treatment were noted between the groups.
Impact on neonatal outcomes merits further study
Dr. Simmons said that he was surprised by the study findings. “We thought if there was an effect, it would be small, but it isn’t,” he told this publication.
“If you combine the severe adverse outcomes, the perineal trauma and the reduction in days in NICU/special care unit, this is a significant impact on morbidity and likely on cost,” and researchers are currently examining data for cost-effectiveness, he said.
“We did not expect the likely large impact on reducing respiratory distress and perineal trauma,” he noted. “These findings have not been previously reported, perhaps because they were not looked for.” By contrast, “we thought here might be reductions in lower gestational age and cesarean delivery, but there was not,” he added.
The findings were limited by several factors including the nonstandardized approach to gestational diabetes treatment and the use of third-trimester treatment targets that had not been tested in earlier trimesters, the researchers noted. Other limitations included the focus on women already at high risk for hyperglycemia; therefore, the results might not generalize to women not at risk, they wrote.
The current study represents a beginning of answers, with data suggesting that early treatment for gestational diabetes reduces severe adverse pregnancy outcomes, days in NICU/special care unit, and perineal trauma, likely from the first trimester, said Dr. Simmons. However, the findings must be interpreted with caution, as criteria that are too low “might lead to more small babies,” he said. “We look forward to working with others to translate these findings into practice,” he added.
Much more research is needed to answer the many questions prompted by the current study, including who did and did not have complications, Dr. Simmons told this publication. Other studies are needed to collect data on cost-effectiveness, as well as consumer views, especially “different perspectives from different parts of the globe,” he said. Although there is not enough evidence yet to draw conclusions about the role of continuous glucose monitoring (CGM) in managing gestational diabetes, many studies are underway; “we look forward to the results,” of these studies, Dr. Simmons added.
Findings support early screening
Gestational diabetes is one of the most common medical complications of pregnancy, and accounts for more than 80% of diabetes-related diagnoses in pregnancy, said Emily Fay, MD, a maternal-fetal medicine specialist at the University of Washington, Seattle, in an interview.
“Previous studies have found that women with gestational diabetes are at higher risk in their pregnancy, including higher chance of developing preeclampsia, higher chance of cesarean delivery, and higher risks for their baby, including risk of shoulder dystocia, birth trauma, and jaundice, and higher birth weights,” she said. “Fortunately, studies have also shown that treatment of gestational diabetes helps lower these risks,” she noted. Currently, patients undergo routine screening for gestational diabetes between 24 and 28 weeks of pregnancy, but some who have risk factors for gestational diabetes may have screening in the early part of pregnancy, said Dr. Fay.
The current findings were not surprising overall, said Dr. Fay, who was not involved in the study. “The study authors looked at a variety of outcomes including neonatal adverse outcomes, neonatal body weight, and pregnancy-related hypertension,” she said.
The researchers found that patients treated early had a lower rate of adverse neonatal outcomes, which was to be expected, Dr. Fay said. “They did not find a difference in neonatal body weight; this also was not surprising, as the women who were not in the early treatment group still received treatment at the time of diagnosis later in pregnancy, which likely helped normalize the weights,” she explained.
“My takeaway from this study is that we should continue to screen patients with risk factors for gestational diabetes early in pregnancy and treat them at the time of diagnosis,” Dr. Fay told this publication. However, barriers that may exist to early treatment involve access to care, including being able to see a provider early in pregnancy, she said. “The treatment for gestational diabetes includes dietary education with diet changes and checking blood sugars frequently. Access to nutrition education can be limited and access to healthy foods can be expensive and difficult to obtain,” she noted. “Checking blood sugars throughout the day can also be difficult for those who are busy or working and who may not have the ability to take time to do this,” she said. However, “these barriers may be overcome by health care reform that improves patient access to and coverage of pregnancy care, improved access and affordability of healthy foods, and employer flexibility to allow the time and space to check blood sugars if needed,” she added.
Looking ahead, the use of continuous glucose monitors in pregnancy is an expanding area of research, said Dr. Fay. “Patients can quickly view their blood sugar without the use of finger sticks, which may help overcome some of the barriers patients may have with using finger sticks,” she noted. “Continuous glucose monitors have been used for those with type 1 and type 2 diabetes with success, and we need to better understand if these can also be helpful in gestational diabetes,” she said. Dr. Fay and colleagues at the University of Washington are currently conducting an ongoing study to explore the use of CGM in gestational diabetes.
The study was supported by the National Health and Medical Research Council, the Region Örebro Research Committee, the Medical Scientific Fund of the Mayor of Vienna, the South Western Sydney Local Health District Academic Unit, and a Western Sydney University Ainsworth Trust Grant. The researchers had no financial conflicts to disclose. Dr. Fay had no relevant financial conflicts to disclose.

Cutaneous vasculitis curtails quality of life
, and its measurement with an organ-specific instrument may catch important disease outcomes better than a generic health-related quality of life index, according to survey responses from participants in the Vasculitis Patient-Powered Research Network (VPPRN).
Although cutaneous vasculitis often causes itching, pain, and ulceration, the impact of the disease on specific health-related quality of life (HRQOL) outcomes has not been systematically assessed, wrote Sarah Mann, MD, of the University of Pittsburgh, and colleagues.
In a study published in JAMA Dermatology, the researchers used the VPPRN to conduct an online survey of adults aged 18 years and older with cutaneous manifestations of vasculitis. The survey was conducted between January 2020 and August 2021.
The primary outcomes of HRQOL were determined using two validated measures. One measured skin-related HRQOL (the Effects of Skin Disease on Quality-of-Life Survey [Skindex-29]), and the other measured general health and well-being (36-Item Short Form Health Survey [SF-36]).
The final analysis included 190 survey responses. The mean age of the respondents was 50.5 years, 84.1% were female, and approximately two-thirds reported a duration of vasculitis of at least 5 years. Respondents’ vasculitides included cutaneous small-vessel vasculitis (14%), IgA vasculitis (6.5%), urticarial vasculitis (8.4%), granulomatosis with polyangiitis (17.6%), microscopic polyangiitis (10.3%), eosinophilic vasculitis (15%), polyarteritis nodosa (3.7%), and other vasculitis types (24.2%).
On the Skindex-29 domains, severely or very severely diminished HRQOL was reported by 77.6% of respondents for emotions, 78.5% for symptoms, 60.7% for functioning, and 75.7% for overall HRQOL.
On the SF-36, the HRQOL was below average on six of eight domains, and approximately half of the patients had summative physical component scores (56%) and mental component scores (52%) below 50.
The HRQOL outcomes of cutaneous vasculitis were worse on the Skindex-29 than the SF-36, the researchers noted. “This discordance may reflect the value of disease or organ-specific measures, which may be able to capture important outcomes of disease even when generic measures do not,” they said.
The study findings were limited by several factors, including the potential lack of generalizability to broader populations of vasculitis patients, the researchers noted. Other limitations included the underrepresentation of male patients and the lack of a disease-specific patient-reported outcome measure, they said.
In addition, “Because half of patients reported having disease which was in remission or mildly active, the study findings may underestimate the true role of active cutaneous vasculitis on HRQOL,” the researchers said.
More studies are needed to assess how HRQOL measures respond to disease treatment and control, the researchers wrote in their discussion. However, the results suggest that cutaneous vasculitis has a significant effect on patients’ perception of their health, as well as on their well-being and symptoms, they said.
The study was supported by the Patient-Centered Outcomes Research Institute and GlaxoSmithKline. Dr. Mann had no financial conflicts to disclose. Several coauthors disclosed relationships with multiple companies, including GlaxoSmithKline.

IVIG shows no impact on VTE risk in dermatomyositis patients
Use of intravenous immunoglobulin (IVIG) had no apparent effect on the risk of venous thromboembolism (VTE) in adults with dermatomyositis (DM), based on data from more than 400 individuals.
DM has been associated with an increased risk of VTE in previous studies, wrote Elizabeth T. Rotrosen, of Boston University and Brigham and Women’s Hospital, Boston, and colleagues. Although IVIG is often effective for DM patients with recalcitrant disease, it carries a boxed warning for increased thrombosis risk; however, the association between IVIG use and VTE risk in DM has not been well examined, the researchers said.
In a study published in JAMA Dermatology, the researchers identified 458 adults with DM based on the European Alliance of Associations for Reumatology/American College of Rheumatology criteria. The mean age of the participants was 51.8 years, 76% were female, and 82% were White. Of these, 178 were treated with IVIG and 280 were not. The mean duration of IVIG treatment was 32.9 months. The researchers used the chi square test to test for independence between binary variables, the Pearson chi square test to test for independence between categorical variables, and the unpaired t test to compare continuous variables in their statistical analysis.
A total of 23 patients experienced DM-associated VTEs; 6 in the IVIG group and 17 in the non-IVIG group (3.4% vs. 5.7%, P = .20), a nonsignificant difference. The patients in the IVIG group who experienced a DM-associated VTE all underwent IVIG treatment within 4 weeks before the event.
The most common risk factors for VTE in both the IVIG and non-IVIG groups were malignant neoplasm (66.7% and 58.8%, respectively), followed by immobilization (16.7% and 35.3%, respectively) and tobacco use (16.7% and 23.5%, respectively).
“Notably, 5 of the IVIG-treated patients with DM who experienced a VTE also had at least 1 additional underlying risk factor for VTE, including 4 with malignant neoplasm,” the researchers wrote.
A total of 76 patients had cancer-associated DM, including 12 treated with IVIG and 64 not treated with IVIG. Of these, 14 experienced a VTE (4 IVIG patients and 10 non-IVIG patients).
The study findings were limited by several factors, including the retrospective design and small number of VTEs. Prospective studies are needed for better assessment of the VTE risk in patients with DM treated with IVIG, the researchers noted. However, the study is the largest known to explore the association between IVIG use and VTE risk in patients with DM, they said, and the results suggest that clinicians may continue IVIG use in these patients with considerations of risks and benefits on an individual basis.

Bundled strategy increased preteen lipid screening
WASHINGTON – A bundled intervention combining point-of-care testing, electronic medical record support, and provider education significantly improved lipid screening rates in children aged 9-11 years, according to data from approximately 100 monthly visits over a 3-year period.
Guidelines from the National Heart, Lung, and Blood Institute currently recommend universal lipid screening for children aged 9-11 years, but screening rates in clinical practice remain low, according to Ruth E. Gardner, MD, of Penn State University, Hershey, and colleagues.
In a poster presented at the Pediatric Academic Societies annual meeting, Dr. Gardner and colleagues shared results of the implementation of a bundled testing protocol designed to improve screening.
The researchers reviewed data on lipid testing within 30 days for all 9- to 11-year-old well child visits at a single center between May 2019 and February 2022. The bundled intervention was introduced in May 2021.
The bundled protocol included in-office capillary testing and provider education. In addition, electronic medical record templates were modified to include prompts for lipid screening at relevant ages, and EMR orders were adjusted to include lipid testing. The researchers also collected targeted provider feedback on individualized screening rates in February 2022.
Screening rates were plotted monthly. For the period from May 2019 through May 2021, the rates averaged 6.5%. However, after the introduction of the bundled intervention, the rate increased to 29.9%. Following targeted provider feedback in February 2022, the researchers found an additional shift to 52.1% through March and April 2022.
The findings were limited by the use of data from a single center, and the researchers used an extended study period to account for disruptions to well-child care in the spring of 2020 related to the COVID-19 pandemic.
However, the results support the effectiveness of a bundled intervention for improving lipid screening rates in children aged 9-11 years, the researchers said, and targeted provider feedback and education could yield additional improvements, they concluded.
Preteen years are an optimal time for screening
“The current study is important because atherosclerosis begins in childhood, and screening at ages 9-11 is an optimal time to begin lifestyle changes to improve overall health and reduce risks of heart disease,” said Margaret Thew, DNP, FNP-BC, of the Medical College of Wisconsin, Milwaukee, in an interview.
Ms. Thew, who was not involved in the study, said, “The number of recommended and required screening items needed in pediatrics is vast, so many providers have to select which items to focus on for their health screenings with these ages.”
Overall, “I was impressed with the improvements that were made in this quality improvement study,” said Ms. Thew.
Barriers to lipid screening in this population include the reduced number of health screenings and immunizations recommended for this age group; the consequence is that access is limited to discuss preventive care opportunities, said Ms. Thew in an interview. Steps to overcome these barriers could include the use of many of the screening tools introduced in the current study, such as point-of-care testing in the office, use of the EMR to remind providers of testing, which can be done during well visits or school physicals, and educating providers about the current guidelines, she noted.
Other strategies to increase screening include moving the immunization series to provide more frequent appointments to children aged 9-11 years to offer education and preventive care, Ms. Thew added.
The study received no outside funding. The researchers had no financial conflicts to disclose. Ms. Thew had no financial conflicts to disclose and serves on the Editorial Advisory Board of Pediatric News.

Screening rates were plotted monthly. For the period from May 2019 through May 2021, the rates averaged 6.5%. However, after the introduction of the bundled intervention, the rate increased to 29.9%. Following targeted provider feedback in February 2022, the researchers found an additional shift to 52.1% through March and April 2022.
The findings were limited by the use of data from a single center, and the researchers used an extended study period to account for disruptions to well-child care in the spring of 2020 related to the COVID-19 pandemic.
However, the results support the effectiveness of a bundled intervention for improving lipid screening rates in children aged 9-11 years, the researchers said, and targeted provider feedback and education could yield additional improvements, they concluded.
Preteen years are an optimal time for screening
“The current study is important because atherosclerosis begins in childhood, and screening at ages 9-11 is an optimal time to begin lifestyle changes to improve overall health and reduce risks of heart disease,” said Margaret Thew, DNP, FNP-BC, of the Medical College of Wisconsin, Milwaukee, in an interview.
Ms. Thew, who was not involved in the study, said, “The number of recommended and required screening items needed in pediatrics is vast, so many providers have to select which items to focus on for their health screenings with these ages.”
Overall, “I was impressed with the improvements that were made in this quality improvement study,” said Ms. Thew.
Barriers to lipid screening in this population include the reduced number of health screenings and immunizations recommended for this age group; the consequence is that access is limited to discuss preventive care opportunities, said Ms. Thew in an interview. Steps to overcome these barriers could include the use of many of the screening tools introduced in the current study, such as point-of-care testing in the office, use of the EMR to remind providers of testing, which can be done during well visits or school physicals, and educating providers about the current guidelines, she noted.
Other strategies to increase screening include moving the immunization series to provide more frequent appointments to children aged 9-11 years to offer education and preventive care, Ms. Thew added.
The study received no outside funding. The researchers had no financial conflicts to disclose. Ms. Thew had no financial conflicts to disclose and serves on the Editorial Advisory Board of Pediatric News.

Interdisciplinary program reduced pediatric pain without pharmacology
WASHINGTON – A nonpharmacologic, interdisciplinary program significantly improved chronic pain in children and the quality of life for their families, based on data from 115 individuals.
Up to 40% of children experience chronic pain that affects their physical, psychosocial, and educational functioning, said Jessica Campanile, BA, a medical student at the University of Pennsylvania, Philadelphia, in a presentation at the Pediatric Academic Societies annual meeting.
Although interdisciplinary pediatric pain rehabilitation programs have shown positive outcomes, very few use only nonpharmacologic treatments, said Ms. Campanile. In addition, few studies have explored the effects of a hospital-based program on the patients and their families.
Ms. Campanile and colleagues conducted a retrospective cohort study of participants in an outpatient pain rehabilitation program at the Children’s Hospital of Philadelphia between April 2016 and December 2019. Patients were evaluated by a pediatric rheumatologist, psychologist, and physical and occupational therapists.
Patients engaged in 2-3 hours of physical therapy (PT) and 2-3 hours of occupational therapy (OT) in a 1:1 ratio at least 5 days a week. Physical activities included stepping into and out of a tub, carrying laundry, and desensitizing to allodynia as needed. Participants also received individual and group cognitive-behavior therapy interventions from psychologists, and psychological support during PT and OT sessions if needed. Parents/caregivers were invited to separate individual and group therapy sessions as part of the program. The median age at admission to the program was 15 years, and 79% of the participants were female. Patients participated the program for a median of 17 days, and 87% were outpatients who came to the hospital for the program.
Pain was assessed based on the 0-10 verbal pain intensity scale, energy was assessed on a scale of 0-100, and functional disability was assessed on a scale of 0-60, with higher scores indicating more pain, more energy, and more self-perceived disability, respectively.
Overall, scores on measures of pain, disability, allodynia, and energy improved significantly from baseline to discharge from the program. Verbal pain intensity scores decreased on average from 7 to 5, disability scores decreased from 26 to 9, the proportion of patients reporting allodynia decreased from 86% to 61%, and the energy level score increased from 70 to 77. The trend continued at the first follow-up visit, conducted 2-3 months after discharge from the program. Notably, pain intensity further decreased from a median of 5 at program completion to a median of 2 at the first follow-up, Ms. Campanile said. Improvements in allodynia also were sustained at the first follow-up.
Quality of life measures related to physical, emotional, social, and cognitive function also improved significantly from baseline to completion of the program.
In addition, scores on a quality of life family impact survey improved significantly; in particular, parent health-related quality of life scores (Parent HRQoL) improved from 60 at baseline to 71 at the end of the program on a scale of 0 to 100. The study findings were limited by several factors including the relatively short duration and use of a convenience sample from a retrospective cohort, with data limited to electronic health records, Ms. Campanile said. The study also was not powered to examine differential treatments based on psychiatric conditions, and any psychiatric conditions were based on self-reports.
However, the results support the value of a nonpharmacologic interdisciplinary program as “a robust treatment for youth with chronic idiopathic pain, for both patients and the family unit,” she said.
“This study also supports the need for and benefit of additional counseling for patients and their caregivers prior to and during enrollment in a pain rehabilitation program,” she concluded.
Study supports effectiveness of drug-free pain management
“The management of pain in any age group can be challenging, especially with current concerns for opioid dependence and abuse,” Cathy Haut, DNP, CPNP-AC, CPNP-PC, a pediatric nurse practitioner in Rehoboth Beach, Del., said in an interview.
“Chronic pain affects daily life for all populations, but for children, adolescents, and their families, it can have a long-lasting impact on growth and development, psychosocial and physical well-being,” Dr. Haut said. “Determining and testing nonpharmacologic alternative methods of pain control are extremely important.”
Given the debilitating effects of chronic pain, and the potential side effects and dependence that have been associated with use of pharmacologic modes of pain control, unique and creative solutions have begun to emerge and need further attention and study, she said.
However, “despite published research supporting the use of alternative and complementary approaches to pain control in children and adolescents, nonpharmacologic, collaborative, interprofessional approaches to pain control have not been widely shared in the literature,” she said.
“Barriers to this type of program include first and foremost a potential lack of financial and workforce-related resources,” Dr. Haut said. “Patient and family attendance at frequent health visits, daily or even every other day, may also hinder success, but opportunities for telehealth and family training to learn physical and occupational skills within this type of program may be beginning solutions.”
Additional research should be conducted at multiple children’s hospitals, with a larger number of children and adolescents at varying ages, with pain related to different diagnoses, and with the inclusion of collaborative methodology, said Dr. Haut. “The current study had some limitations, including the small sample size, predominantly female sex, and a short participation time frame utilizing retrospective review. Completing prospective research over a longer time frame can also yield generalizable results applicable to varied populations.”
The study received no outside funding. Ms. Campanile had no financial conflicts to disclose. Dr. Haut had no financial conflicts to disclose, and serves on the editorial advisory board of Pediatric News.

Improving swallowing may mitigate COPD exacerbations
Dysphagia treatment may be a way to reduce risk for chronic obstructive pulmonary disease (COPD) exacerbations, according to Yoshitaka Oku, MD, of Hyogo Medical University, Nishinomiya, Japan.
Gastroesophageal regurgitation disease (GERD) is known to be associated with exacerbations in COPD, but previous studies have shown little impact of standard GERD therapy on COPD exacerbations. However, additional research indicates that delayed swallowing contributes to COPD exacerbations, as reported in a research review.
In an article published recently in Respiratory Physiology & Neurobiology,
Swallowing disorder (dysphagia) is a common comorbidity in patients with COPD and has been reported at a 17%-20% greater prevalence in those with COPD, compared with controls, the researchers said.
Patients with COPD have altered swallowing behavior because of several factors, including decreased maximal laryngeal elevation, Dr. Oku said. Individuals with COPD “are also prone to laryngeal penetration and aspiration when swallowing large volumes of liquid and tend to follow an inspiratory-swallow-expiratory (I-SW-E) pattern when swallowing large volumes,” he explained.
Dr. Oku conducted prospective studies to investigate the impact of breathing-swallowing discoordination on COPD exacerbation. He found that discoordination in swallowing patterns and the inability to produce airway protective mechanism (such as the I-SW-E pattern) may contribute to more frequent aspirations and more frequent exacerbations.
Dr. Oku also examined whether CPAP and bilevel positive airway pressure (BiPAP) might affect breathing-swallowing coordination in healthy controls and patients with COPD. They found a decrease in breathing-swallowing coordination with CPAP, but not BiPAP, in both controls and stable COPD patients. “During BiPAP, a brief negative flow associated with relaxation of the pharyngeal constrictor muscle triggers inspiratory support, which results in the SW-I pattern,” Dr. Oku noted.
Dr. Oku also wrote that interferential current stimulation (IFC) has been used to stimulate muscles. Studies of transcutaneous electrical sensory stimulation using IFC (IFC-TESS) as an intervention to improve swallowing have shown some success, and also may improve airway protection.
“However, its safety and efficacy in patients with COPD remains unknown,” he wrote. Dr. Oku conducted a study of stable COPD patients and found that repeated salivary swallow test (RSST) scores improved significantly after an IFC-TESS intervention.
Breathing-swallowing discoordination may be an early indicator of swallowing disorder in COPD, and interventions can improve these disorders, Dr. Oku added. However, more research is needed to explore whether interventions to improve dysphagia reduce the frequency of exacerbations in COPD patients, he concluded.
The study was supported by a grant from JSPS KAKENHI. Dr. Oku serves as a senior managing director at EuSense Medical Co.
