Ob.Gyns. Can Help Patients Manage Weight With Anti-Obesity Medications
SAN FRANCISCO — An estimated two out of five adult women in the United States have obesity, and given the potential challenges of losing pregnancy weight postpartum or staving off the weight gain associated with menopause, women are likely to be receptive toward weight management help from their ob.gyns. A whole new armamentarium of anti-obesity medications has become available in the past decade, providing physicians and patients with more treatment options.
Ob.gyns. are therefore well-poised to offer counseling and treatment for obesity management for their patients, Johanna G. Finkle, MD, clinical assistant professor of obstetrics and gynecology and a weight management specialist at the University of Kansas Heath System, told attendees at the annual clinical and scientific meeting of the American College of Obstetricians and Gynecologists. Dr. Finkle provided an extensive overview of what ob.gyns. need to know if they are interested in prescribing anti-obesity medications or simply providing their patients with information about the available drugs.
Kitila S. Heyward, MD, an ob.gyn. at Atrium Health in Monroe, North Carolina, who attended the talk, tries to prescribe anti-obesity medications but has run into roadblocks that Dr. Finkle’s talk helped her understand how to overcome.
“I thought it was very helpful because [I] and one of my midwives, in practice, have been trying to get things prescribed, and we can’t figure out the loopholes,” Dr. Heyward said. “Also, the failure rates are really helpful to us so that we know how to counsel people.”
Even for clinicians who aren’t prescribing these medications, Dr. Heyward said the talk was illuminating. “It offered a better understanding of the medications that your patients are on and how it can affect things like birth control, management of surgery, pregnancy, and things along those lines from a clinical day-by-day standpoint,” she said.
Starting With the Basics
Dr. Finkle began by emphasizing the importance of using patient-first language in discussing obesity, which means using terms such as “weight, excess weight, overweight, body mass index,” and “affected by obesity” instead of “obese, morbidly obese, heaviness, or large.” She also cited the Obesity Medicine Association’s definition of obesity: “a chronic, relapsing and treatable multifactorial, neurobehavioral disease, wherein an increase in body fat promotes adipose tissue dysfunction and abnormal fat mass physical forces, resulting in adverse metabolic, biomechanical, and psychosocial health consequences.”
Though Dr. Finkle acknowledged the limitations of relying on BMI for defining obesity, it remains the standard tool in current practice, with a BMI of 25-29.9 defining overweight and a BMI of 30 or greater defining obesity. Other diagnostic criteria for obesity in women, however, include a percentage body fat over 32% or a waist circumference of more than 35 inches.
“Women are at risk for weight gain through their entire lifespan” Dr. Finkle said, and in women with polycystic ovarian syndrome, 60%-80% have pre-obesity or obesity. In menopause, the triple threat of decreased estrogen, decreased activity, and changes in diet all contribute to obesity risk and no evidence suggests that hormone therapy can prevent weight gain.
Healthy nutrition, physical activity, and behavioral modification remain key pillars of weight management, but interventions such as surgery or medications are also important tools, she said.
“One size does not fit all in terms of treatment,” Dr. Finkle said. ”When I talk to a patient, I think about other medical complications that I can treat with these medications.”
Women for whom anti-obesity medications may be indicated are those with a BMI of 30 or greater, and those with a BMI of at least 27 along with at least one obesity-related comorbidity, such as hypertension, high cholesterol, diabetes, or sleep apnea. The goal of treating obesity with medication is at least a 5%-10% reduction of body weight.
Three Pharmacotherapy Categories
Dr. Finkle reviewed three basic categories of anti-obesity medications: Food and Drug Administration–approved short-term and long-term medications and then off-label drugs that can also aid in healthy weight loss. Short-term options include phentermine, diethylpropion, phendimetrazine, and benzphetamine. Long-term options include orlistat, phentermine/topiramate ER, naltrexone HCl/bupropion HCl ER, and the three GLP-1 receptor agonist drugs, liraglutide, semaglutide, and tirzepatide.
The short-term medications are stimulants that increase satiety, but adverse effects can include tachycardia, hypertension, insomnia, dry mouth, constipation, and diarrhea.
These medications are contraindicated for anyone with uncontrolled hypertension, hyperthyroidism, cardiovascular disease, MAOI use, glaucoma, or history of substance use. The goal is a 5% weight loss in 3 months, and 3 months is the maximum prescribing term.
Then Dr. Finkle reviewed the side effects and contraindications for the oral long-term medications. Orlistat, which can aid in up to 5% weight loss, can result in oily stools and fecal incontinence and is contraindicated for people with chronic malabsorption or cholestasis.
Phentermine/topiramate ER, which can aid in up to 10% weight loss, can result in hypertension, paresthesia, or constipation, and is contraindicated for those with glaucoma, hyperthyroidism, and kidney stones. After the starting dose of 3.75 mg/23 mg, Dr. Finkle increases patients’ dose every 2 weeks, ”but if they’re not tolerating it, if they’re having significant side effects, or they’re losing weight, you do not increase the medication.”
Side effects of naltrexone HCl/bupropion HCl ER, which can lead to 5%-6% weight loss, can include hypertension, suicidal ideation, and glaucoma, and it’s contraindicated in those taking opioids or with a history of seizures or anorexia.
The GLP-1 Receptor Agonists
Next Dr. Finkle discussed the newest but most effective medications, the GLP-1 agonists liraglutide, semaglutide, and tirzepatide. The main contraindications for these drugs are a personal or family history of medullary thyroid cancer, multiple endocrine neoplasia type II syndrome, or any hypersensitivity to this drug class. The two main serious risks are pancreatitis — a 1% risk — and gallstones. Though Dr. Finkle included suicidal ideation as a potential risk of these drugs, the most recent evidence suggests there is no link between suicidal ideation and GLP-1 agonists. The most common side effects are nausea, vomiting, diarrhea, constipation, dyspepsia, and an increased heart rate, though these eventually resolve.
“We always start low with these medications,” Dr. Finkle said, and then titrate the dose up each week, “but if they are having awful side effects, just stay on that dose longer.”
The mechanisms of all three drugs for treating obesity are similar; they work to curb central satiety and slow gastric emptying, though they also have additional mechanisms with benefits for blood glucose levels and for the liver and heart.
- Liraglutide, the first of these drugs approved, is a daily subcutaneous injection that starts at a dose of 0.6 mg and goes up to 3 mg. Patients should lose 4% of weight in 16 weeks or else they are non-responders, Dr. Finkle said.
- Semaglutide, a GLP-1 agonist given as a weekly subcutaneous injection, starts at a dose of 0.25 mg and goes up to 2.4 mg; patients should expect a 5% weight loss in 16 weeks if they are responders. Long term, however, patients lose up to an average 15% of body weight with semaglutide; a third of patients lost more than 20% of body weight in clinical trials, compared with 7%-8% body weight loss with liraglutide. An additional benefit of semaglutide is a 20% reduction in risk of cardiovascular disease.
- Tirzepatide is a combined GLP-1 and GIP agonist, also delivered as a weekly subcutaneous injection, that should result in an estimated 5% weight loss in 16 weeks for responders. But tirzepatide is the most effective of the three, with 91% of patients losing at least 5% body weight and more than half of patients (56%) losing at least 20%.
The big drawbacks to the GLP-1 agonists, however, are their high cost, common lack of insurance coverage, and continued shortages. Dr. Finkle recommended using manufacturer coupons, comparison shopping on Good Rx, and appealing prior authorization requirements to help patients pay for the GLP-1 agonists.
“Drug availability is my second problem. There’s not enough drug,” she said, and her patients often have to call around to different pharmacies to find out which ones are carrying the drug and at what doses. She will sometimes switch their doses as needed based on availability.
It’s also important for physicians to be aware of guidance from the American Society of Anesthesiologists regarding GLP-1 agonist use prior to surgery because of their slowed gastric-emptying mechanism. To reduce the risk of aspiration, patients undergoing general anesthesia should not take liraglutide on the day of surgery, and semaglutide and tirzepatide should be held for 1 week prior to the procedure. New research in JAMA Surgery, however, suggests holding these medications for longer than a week may be wiser.
Getting Patients Started
All the short-term and long-term medications are contraindicated during pregnancy and breastfeeding, Dr. Finkle said. Animal studies with GLP-1 agonists suggest adverse fetal effects when used during pregnancy, but the limited data in human studies so far have not shown a risk of major malformations. Dr. Finkle said the recommendations for now are to stop all GLP-1 receptor agonist drugs 2 months before patients attempt to become pregnant and not to begin them again until after they are no longer breastfeeding.
Finally, Dr. Finkle reviewed off-label medications that can result in modest weight loss, including topiramate, phentermine (not to be used for longer than 12 weeks), bupropion, naltrexone, and metformin. Metformin is likely to result in only 2% weight loss, but it may enhance the effects of GLP-1s, she said.
For ob.gyns. who want to get their patients started on one of these medications, Dr. Finkle first recommends asking patients if it’s okay to discuss their weight. ”Studies show that if you just ask permission to discuss someone’s weight, they go on to lose weight and lose more than someone who has never been asked,” Dr. Finkle said. Then she takes a history.
”When I see a patient, I ask, ‘Tell me why you’re here today,’ ” Dr. Finkle said.
This gives me a lot of insight as to why they’re coming in and it helps me understand where they’re at in terms of other things, such as depression or anxiety with weight, and it helps me to tailor my treatment.”
A full medical history is important for learning about potential contraindications or picking medications that might help with other conditions, such as topiramate for migraines. Finally, Dr. Finkle advises a lab screening with a comprehensive metabolic panel, lipid panel, HbA1c, and vitamin D.
“The [comprehensive metabolic panel] allows me to know about creatinine and liver function,” she said. If these are elevated, she will still prescribe GLP-1s but will monitor the values more closely. “Then I discuss options with the patient. They may be eligible for bariatric surgery or medications. We talk about lifestyle behavioral management, and then I go through the medications and we set goals.”
Goals include nutrition and exercise; start modest and have them work their way up by doing activities they enjoy. In addition, patients taking GLP-1s need to eat enough protein — 80 to 100 grams a day, though she starts them at 60 grams — and do regular muscle strengthening since they can lose muscle mass.
Indications for referral to an obesity medicine specialist are a history of gastric bypass/sleeve surgery, having type 2 diabetes, having an eating disorder, or having failed one of these anti-obesity medications.
Finally, Dr. Finkle reviewed medications that can cause weight gain: medroxyprogesterone acetate for birth control; beta blockers for hypertension or migraine; the antidepressants amitriptyline, paroxetine, venlafaxine, and trazodone; the mood stabilizers gabapentin, lithium, valproate, and carbamazepine; and diphenhydramine and zolpidem for sleep.
No external funding was used for the talk. Dr. Finkle and Dr. Heyward had no disclosures.

This gives me a lot of insight as to why they’re coming in and it helps me understand where they’re at in terms of other things, such as depression or anxiety with weight, and it helps me to tailor my treatment.”
A full medical history is important for learning about potential contraindications or picking medications that might help with other conditions, such as topiramate for migraines. Finally, Dr. Finkle advises a lab screening with a comprehensive metabolic panel, lipid panel, HbA1c, and vitamin D.
“The [comprehensive metabolic panel] allows me to know about creatinine and liver function,” she said. If these are elevated, she will still prescribe GLP-1s but will monitor the values more closely. “Then I discuss options with the patient. They may be eligible for bariatric surgery or medications. We talk about lifestyle behavioral management, and then I go through the medications and we set goals.”
Goals include nutrition and exercise; start modest and have them work their way up by doing activities they enjoy. In addition, patients taking GLP-1s need to eat enough protein — 80 to 100 grams a day, though she starts them at 60 grams — and do regular muscle strengthening since they can lose muscle mass.
Indications for referral to an obesity medicine specialist are a history of gastric bypass/sleeve surgery, having type 2 diabetes, having an eating disorder, or having failed one of these anti-obesity medications.
Finally, Dr. Finkle reviewed medications that can cause weight gain: medroxyprogesterone acetate for birth control; beta blockers for hypertension or migraine; the antidepressants amitriptyline, paroxetine, venlafaxine, and trazodone; the mood stabilizers gabapentin, lithium, valproate, and carbamazepine; and diphenhydramine and zolpidem for sleep.
No external funding was used for the talk. Dr. Finkle and Dr. Heyward had no disclosures.

ART Safe for Breast Cancer Survivors with BRCA1/2 Mutations
For breast cancer survivors harboring BRCA1/2 gene mutations, the prospect of future pregnancy often raises concerns because of limited data on the safety of assisted reproductive techniques (ART) in this population. However,
“Our primary aim was to evaluate the safety profile of ART in this high-risk population by comparing maternal and fetal outcomes between those who conceived spontaneously versus those using ART,” explained Matteo Lambertini, MD, PhD, during his talk at the conference. “We found no statistically significant differences in pregnancy complications or fetal abnormalities.” Dr. Lambertini is an associate professor and medical oncologist at the University of Genova and IRCCS Policlinico San Martino Hospital, Genova, Italy.
Unmet Fertility Needs for Women With Breast Cancer
With the rising rates of early-onset breast cancer and improved survival outcomes with new therapies, the number of long-term breast cancer survivors is increasing. Fertility preservation and future reproductive choices are important considerations for young patients with breast cancer, especially for high-risk patients carrying pathogenic BRCA1/2 mutations. During his talk, Dr. Lambertini explained that defects in DNA damage repair due to BRCA1/2 mutations, in addition to chemotherapy after breast cancer diagnosis, can lead to premature menopause.
According to Dr. Lambertini, physicians face challenges in counseling these patients regarding the potential risks and benefits of pursuing pregnancy after cancer treatment because of the limited evidence available on the safety of ART in BRCA1/2 mutation carriers.
“Clinicians have to counsel BRCA carriers based on very limited data about the safety of pursuing pregnancy with ART after a breast cancer diagnosis,” he said during his presentation.
Study Design and Patient Population
The retrospective cohort study pooled data from 78 centers worldwide to explore ART outcomes in BRCA1/2 mutation carriers. The analysis included 4732 women diagnosed with stage I-III breast cancer at age 40 years or younger, all harboring a pathogenic BRCA1 or BRCA2 variant.
Among these high-risk patients, 543 became pregnant after completing cancer treatment; of these, 436 conceived naturally and 107 used ART. In the ART group, 45.5% underwent oocyte or embryo cryopreservation at breast cancer diagnosis, 33.3% underwent ovarian stimulation for in vitro fertilization after cancer treatment, and 21.2% underwent embryo transfer following oocyte donation.
Dr. Janice Tsang, MD, a clinical oncology specialist and assistant professor at the University of Hong Kong who was not involved in this study, highlighted that this is the largest study focusing on ART safety in young patients with BRCA1/2 mutations. “With over 500 BRCA1/2 mutation carriers studied across nearly 80 sites, the cohort analysis had sufficient statistical power and global representation to detect potential safety signals with ART utilization, unlike prior smaller studies,” she said. Dr. Tsang, a clinical oncology specialist and assistant professor at the University of Hong Kong who was not involved in this study, served as a discussant, providing her expert opinion on the findings presented by Dr. Lambertini.
No Increased Risks for Pregnancy and Fetal Outcomes
Although women using ART had slightly higher miscarriage rates (11.3% versus 8.8%) and lower rates of induced abortion (0.9% versus 8.3%) than women with spontaneous conceptions, the analysis revealed no statistically significant differences in the frequency of pregnancy complications, delivery complications, or congenital abnormalities between those who received ART and those who conceived naturally.
Dr. Lambertini explained that variations in baseline characteristics, such as age, may have contributed to differences in miscarriage rates.
“Patients in the ART group tended to be older at the time of conception, with a median age of 37.1 years, compared with 34.3 years in the spontaneous pregnancy group,” he said, during his presentation. Women in the ART group also more frequently had hormone receptor–positive breast cancer (43.4% versus 30.8%) and longer median time from diagnosis to conception (4.2 versus 3.3 years).
No Adverse Effects on Breast Cancer Prognosis
At a median follow-up of 5.2 years from conception, there was no detrimental effect of ART on disease-free survival for carriers of pathogenic BRCA1/2 variants who were treated for breast cancer. The ART group showed 13 (13.1%) recurrence events, compared with 118 (27.1%) recurrences in the spontaneous pregnancy group (adjusted hazard ratio, 0.72; 95% CI, 0.38-1.33; P = .147).
“The risk of cancer recurrence was comparable between those using and not using ART to become pregnant after their breast cancer diagnosis and treatment, and the small number of recurrence events in the ART group mostly involved locoregional recurrences,” Dr. Lambertini noted during his talk.
Moreover, breast cancer–specific survival and overall survival appeared to be similar between the two groups, although the small number of deaths precluded the conduction of formal analysis.
“These survival data suggest that utilizing ART does not appear to negatively impact the prognosis or course of the underlying breast cancer,” Dr. Lambertini said during the discussion.
Clinical Implications and Future Work
According to Dr. Lambertini, these results are incredibly valuable for clinicians counseling young breast cancer survivors with pathogenic BRCA1/2 mutations who wish to have biological children.
“Given the interest of patients in having their own family and for some of them in avoiding the transmission of the BRCA1/2 pathogenic variants, our results are critical in improving the oncofertility counseling of young women with breast cancer,” said Dr. Lambertini during his presentation. “We can reassure patients that pursuing ART does not appear to worsen their cancer prognosis or compromise pregnancy outcomes compared to spontaneous conceptions.”
During her discussion session, Dr. Tsang echoed the clinical implications of these findings, emphasizing that, by incorporating this evidence into clinical practice, healthcare providers can better support patients in making informed choices regarding fertility preservation and family planning after cancer treatment.
“Though this study is [retrospective] with a relatively small number, these real-world findings make a major contribution to our limited evidence base on ART safety for cancer survivors carrying BRCA1/2 mutations,” she said.
She cautioned, however, that there remain several unanswered questions and uncertainties. “We need prospective data with a larger sample size to confirm the safety of ART in this population, as well as studies to assess whether different types of ART have different safety profiles.”
Dr. Lambertini concluded his talk by saying, “While waiting for prospective studies to confirm our results, fertility preservation at diagnosis of early breast cancer should be offered to all women interested in future fertility, including BRCA carriers.”

Clinicians Call for Easing FDA Warnings on Low-Dose Estrogen
Charles Powell, MD, said he sometimes has a hard time persuading patients to start on low-dose vaginal estrogen, which can help prevent urinary tract infections and ease other symptoms of menopause.
Many women fear taking these vaginal products because of what Dr. Powell considers excessively strong warnings about the risk for cancer and cardiovascular disease linked to daily estrogen pills that were issued in the early 2000s.
He is advocating for the US Food and Drug Administration (FDA) to remove the boxed warning on low-dose estrogen. His efforts are separate from his roles as an associate professor of urology at the Indiana University School of Medicine, and as a member of the American Urological Association (AUA), Dr. Powell said.
In his quest to find out how to change labeling, Dr. Powell has gained a quick education about drug regulation. He has enlisted Representative Jim Baird (R-IN) and Senator Mike Braun (R-IN) to contact the FDA on his behalf, while congressional staff guided him through the hurdles of getting the warning label changed. For instance, a manufacturer of low-dose estrogen may need to become involved.
“You don’t learn this in med school,” Dr. Powell said in an interview.
With this work, Dr. Powell is wading into a long-standing argument between the FDA and some clinicians and researchers about the potential harms of low-dose estrogen.
He is doing so at a time of increased interest in understanding genitourinary syndrome of menopause (GSM), a term coined a decade ago by the International Society for the Study of Women’s Sexual Health and the North American Menopause Society to cover “a constellation of conditions” related to urogenital atrophy.
Symptoms of GSM include vaginal dryness and burning and recurrent urinary tract infections.
The federal government in 2022 began a project budgeted with nearly $1 million to review evidence on treatments, including vaginal and low-dose estrogen. The aim is to eventually help the AUA develop clinical guidelines for addressing GSM.
In addition, a bipartisan Senate bill introduced in May calls for authorizing $125 million over 5 years for the National Institutes of Health (NIH) to fund research on menopause. Senator Patty Murray (D-WA), the lead sponsor of the bill, is a longtime advocate for women’s health and serves as chairwoman for the Senate Appropriations Committee, which largely sets the NIH budget.
“The bottom line is, for too long, menopause has been overlooked, underinvested in and left behind,” Sen. Murray said during a May 2 press conference. “It is well past time to stop treating menopause like some kind of secret and start treating it like the major mainstream public health issue it is.”
Evidence Demands
Increased federal funding for menopause research could help efforts to change the warning label on low-dose estrogen, according to JoAnn Manson, MD, chief of preventive medicine at Brigham and Women’s Hospital in Boston.
Dr. Manson was a leader of the Women’s Health Initiative (WHI), a major federally funded research project launched in 1991 to investigate if hormone therapy and diet could protect older women from chronic diseases related to aging.
Before the WHI, clinicians prescribed hormones to prevent cardiovascular disease, based on evidence from earlier research.
But in 2002, a WHI trial that compared estrogen-progestin tablets with placebo was halted early because of disturbing findings, including an association with higher risk for breast cancer and cardiovascular disease.
Compared with placebo, for every 10,000 women taking estrogen plus progestin annually, incidences of cardiovascular disease, stroke, pulmonary embolism, and invasive breast cancer were seven to eight times higher.
In January 2003, the FDA announced it would put a boxed warning about cardiovascular risk and cancer risk on estrogen products, reflecting the WHI finding.
The agency at the time said clinicians should work with patients to assess risks and benefits of these products to manage the effects of menopause.
But more news on the potential harms of estrogen followed in 2004: A WHI study comparing estrogen-only pills with placebo produced signals of a small increased risk for stroke, although it also indicated no excess risk for breast cancer for at least 6.8 years of use.
Dr. Manson and the North American Menopause Society in 2016 filed a petition with the FDA to remove the boxed warning that appears on the front of low-dose estrogen products. The group wanted the information on risks moved to the usual warning section of the label.
Two years later, the FDA rejected the petition, citing the absence of “well-controlled studies,” to prove low-dose topical estrogen poses less risk to women than the high-dose pills studied in the WHI.
The FDA told this news organization that it stands by the decisions in its rejection of the petition.
Persuading the FDA to revise the labels on low-dose estrogen products likely will require evidence from randomized, large-scale studies, Dr. Manson said. The agency has not been satisfied to date with findings from other kinds of studies, including observational research.
“Once that evidence is available that the benefit-risk profile is different for different formulations and the evidence is compelling and definitive, that warning should change,” Dr. Manson told this news organization.
But the warning continues to have a chilling effect on patient willingness to use low-dose vaginal estrogen, even with the FDA’s continued endorsement of estrogen for menopause symptoms, clinicians told this news organization.
Risa Kagan, MD, a gynecologist at Sutter Health in Berkeley, California, said in many cases her patients’ partners also need to be reassured. Dr. Kagan said she still sees women who have had to discontinue sexual intercourse because of pain. In some cases, the patients will bring the medicine home only to find that the warnings frighten their spouses.
“The spouse says, ‘Oh my God, I don’t want you to get dementia, to get breast cancer, it’s not worth it, so let’s keep doing outercourse’,” meaning sexual relations without penetration, Dr. Kagan said.
Difficult Messaging
From the initial unveiling of disappointing WHI results, clinicians and researchers have stressed that women could continue using estrogen products for managing symptoms of menopause, even while advising strongly against their continued use with the intention of preventing heart disease.
Newly published findings from follow-ups of WHI participants may give clinicians and patients even more confidence for the use of estrogen products in early menopause.
According to the study, which Dr. Manson coauthored, younger women have a low risk for cardiovascular disease and other associated conditions when taking hormone therapy. Risks attributed to these drugs were less than one additional adverse event per 1000 women annually. This population may also derive significant quality-of-life benefits for symptom relief.
Dr. Manson told this news organization that estrogen in lower doses and delivered through the skin as a patch or gel may further reduce risks.
“The WHI findings should never be used as a reason to deny hormone therapy to women in early menopause with bothersome menopausal symptoms,” Dr. Manson said. “Many women are good candidates for treatment and, in shared decision-making with their clinicians, should be able to receive appropriate and personalized healthcare for their needs.”
But the current FDA warning label makes it difficult to help women understand the risk and benefits of low-dose estrogen, according to Stephanie Faubion, MD, MBA, medical director at the North American Menopause Society and director of Mayo Clinic’s Center for Women’s Health in Jacksonville, Florida.
Clinicians now must set aside time to explain the warnings to women when they prescribe low-dose estrogen, Dr. Faubion said.
“The package insert is going to look scary: I prepare women for that because otherwise they often won’t even fill it or use it.”

“Once that evidence is available that the benefit-risk profile is different for different formulations and the evidence is compelling and definitive, that warning should change,” Dr. Manson told this news organization.
But the warning continues to have a chilling effect on patient willingness to use low-dose vaginal estrogen, even with the FDA’s continued endorsement of estrogen for menopause symptoms, clinicians told this news organization.
Risa Kagan, MD, a gynecologist at Sutter Health in Berkeley, California, said in many cases her patients’ partners also need to be reassured. Dr. Kagan said she still sees women who have had to discontinue sexual intercourse because of pain. In some cases, the patients will bring the medicine home only to find that the warnings frighten their spouses.
“The spouse says, ‘Oh my God, I don’t want you to get dementia, to get breast cancer, it’s not worth it, so let’s keep doing outercourse’,” meaning sexual relations without penetration, Dr. Kagan said.
Difficult Messaging
From the initial unveiling of disappointing WHI results, clinicians and researchers have stressed that women could continue using estrogen products for managing symptoms of menopause, even while advising strongly against their continued use with the intention of preventing heart disease.
Newly published findings from follow-ups of WHI participants may give clinicians and patients even more confidence for the use of estrogen products in early menopause.
According to the study, which Dr. Manson coauthored, younger women have a low risk for cardiovascular disease and other associated conditions when taking hormone therapy. Risks attributed to these drugs were less than one additional adverse event per 1000 women annually. This population may also derive significant quality-of-life benefits for symptom relief.
Dr. Manson told this news organization that estrogen in lower doses and delivered through the skin as a patch or gel may further reduce risks.
“The WHI findings should never be used as a reason to deny hormone therapy to women in early menopause with bothersome menopausal symptoms,” Dr. Manson said. “Many women are good candidates for treatment and, in shared decision-making with their clinicians, should be able to receive appropriate and personalized healthcare for their needs.”
But the current FDA warning label makes it difficult to help women understand the risk and benefits of low-dose estrogen, according to Stephanie Faubion, MD, MBA, medical director at the North American Menopause Society and director of Mayo Clinic’s Center for Women’s Health in Jacksonville, Florida.
Clinicians now must set aside time to explain the warnings to women when they prescribe low-dose estrogen, Dr. Faubion said.
“The package insert is going to look scary: I prepare women for that because otherwise they often won’t even fill it or use it.”

Charles Powell, MD, said he sometimes has a hard time persuading patients to start on low-dose vaginal estrogen, which can help prevent urinary tract infections and ease other symptoms of menopause.
Many women fear taking these vaginal products because of what Dr. Powell considers excessively strong warnings about the risk for cancer and cardiovascular disease linked to daily estrogen pills that were issued in the early 2000s.
He is advocating for the US Food and Drug Administration (FDA) to remove the boxed warning on low-dose estrogen. His efforts are separate from his roles as an associate professor of urology at the Indiana University School of Medicine, and as a member of the American Urological Association (AUA), Dr. Powell said.
In his quest to find out how to change labeling, Dr. Powell has gained a quick education about drug regulation. He has enlisted Representative Jim Baird (R-IN) and Senator Mike Braun (R-IN) to contact the FDA on his behalf, while congressional staff guided him through the hurdles of getting the warning label changed. For instance, a manufacturer of low-dose estrogen may need to become involved.
“You don’t learn this in med school,” Dr. Powell said in an interview.
With this work, Dr. Powell is wading into a long-standing argument between the FDA and some clinicians and researchers about the potential harms of low-dose estrogen.
He is doing so at a time of increased interest in understanding genitourinary syndrome of menopause (GSM), a term coined a decade ago by the International Society for the Study of Women’s Sexual Health and the North American Menopause Society to cover “a constellation of conditions” related to urogenital atrophy.
Symptoms of GSM include vaginal dryness and burning and recurrent urinary tract infections.
The federal government in 2022 began a project budgeted with nearly $1 million to review evidence on treatments, including vaginal and low-dose estrogen. The aim is to eventually help the AUA develop clinical guidelines for addressing GSM.
In addition, a bipartisan Senate bill introduced in May calls for authorizing $125 million over 5 years for the National Institutes of Health (NIH) to fund research on menopause. Senator Patty Murray (D-WA), the lead sponsor of the bill, is a longtime advocate for women’s health and serves as chairwoman for the Senate Appropriations Committee, which largely sets the NIH budget.
“The bottom line is, for too long, menopause has been overlooked, underinvested in and left behind,” Sen. Murray said during a May 2 press conference. “It is well past time to stop treating menopause like some kind of secret and start treating it like the major mainstream public health issue it is.”
Evidence Demands
Increased federal funding for menopause research could help efforts to change the warning label on low-dose estrogen, according to JoAnn Manson, MD, chief of preventive medicine at Brigham and Women’s Hospital in Boston.
Dr. Manson was a leader of the Women’s Health Initiative (WHI), a major federally funded research project launched in 1991 to investigate if hormone therapy and diet could protect older women from chronic diseases related to aging.
Before the WHI, clinicians prescribed hormones to prevent cardiovascular disease, based on evidence from earlier research.
But in 2002, a WHI trial that compared estrogen-progestin tablets with placebo was halted early because of disturbing findings, including an association with higher risk for breast cancer and cardiovascular disease.
Compared with placebo, for every 10,000 women taking estrogen plus progestin annually, incidences of cardiovascular disease, stroke, pulmonary embolism, and invasive breast cancer were seven to eight times higher.
In January 2003, the FDA announced it would put a boxed warning about cardiovascular risk and cancer risk on estrogen products, reflecting the WHI finding.
The agency at the time said clinicians should work with patients to assess risks and benefits of these products to manage the effects of menopause.
But more news on the potential harms of estrogen followed in 2004: A WHI study comparing estrogen-only pills with placebo produced signals of a small increased risk for stroke, although it also indicated no excess risk for breast cancer for at least 6.8 years of use.
Dr. Manson and the North American Menopause Society in 2016 filed a petition with the FDA to remove the boxed warning that appears on the front of low-dose estrogen products. The group wanted the information on risks moved to the usual warning section of the label.
Two years later, the FDA rejected the petition, citing the absence of “well-controlled studies,” to prove low-dose topical estrogen poses less risk to women than the high-dose pills studied in the WHI.
The FDA told this news organization that it stands by the decisions in its rejection of the petition.
Persuading the FDA to revise the labels on low-dose estrogen products likely will require evidence from randomized, large-scale studies, Dr. Manson said. The agency has not been satisfied to date with findings from other kinds of studies, including observational research.
“Once that evidence is available that the benefit-risk profile is different for different formulations and the evidence is compelling and definitive, that warning should change,” Dr. Manson told this news organization.

Hypofractionated Radiotherapy Limits Toxic Effects in Cervical Cancer
TOPLINE:
POHIM-CCRT trial suggested.
results from the phase 2METHODOLOGY:
- To date, no studies have assessed the treatment outcomes and toxic effects of hypofractionated IMRT following radical hysterectomy in patients with cervical cancer undergoing curative radiotherapy.
- The team analyzed outcomes from 79 patients undergoing hypofractionated IMRT for cervical cancer after radical hysterectomy and pelvic lymph node dissection.
- Patients were a median age of 48; 29.5% had stage IB to IIA disease, another 29.5% had stage IIB disease, and 41% had stage III disease. Patients also had at least one of the following criteria following radical hysterectomy and pelvic lymph node dissection: lymph node metastasis (39.7%), parametrial invasion (54.4%), and positive resection margin (5.1%).
- The prescribed dose to the planning target volume was 40 Gy, delivered in 16 fractions to the whole pelvis, with any type of IMRT permitted. Overall, 71 patients also underwent concurrent weekly cisplatin (40 mg/m2 of body surface area for three cycles), and eight received fluorouracil (1000 mg/m2 on days 1-5) with cisplatin (60 mg/m2 for two cycles).
- The primary endpoint was the incidence of acute grade 3 or higher gastrointestinal tract, genitourinary, and hematologic toxic effects during radiotherapy or within 3 months of completing radiotherapy.
TAKEAWAY:
- After radiotherapy, only two patients (2.5%) experienced acute grade 3 or higher toxic effects. One was hospitalized for enterocolitis on the last day of radiotherapy and developed grade 3 anemia 3 months after completing radiotherapy; the other experienced hematologic toxic effects and also developed grade 3 anemia 3 months after completing radiotherapy.
- No patients experienced late grade 3 or higher toxic effects.
- When assessing toxic effects of any grade, acute and late gastrointestinal tract toxicities occurred in 76% and 31.6% of patients, respectively; acute and late genitourinary toxicities, all grade 1, occurred in 19% and 24.1% of patients, respectively; and hematologic toxicities occurred in 29.1% and 6.3% of patients, respectively.
- Overall, at 3 years, 79.3% of patients were disease-free and 98% were alive. After a median follow-up of 43 months, 16 patients (20.3%) experienced disease recurrence, four of whom were salvaged and three of whom died.
IN PRACTICE:
“This nonrandomized controlled trial is the first prospective trial, to our knowledge, to show acceptable acute toxic effects of hypofractionated IMRT for cervical cancer in a postoperative concurrent chemoradiotherapy setting,” the authors said, adding that the rate of grade 3 or higher acute toxic effects of 2.5% reported in this study was “substantially lower than our initial hypothesis of less than 15%.”
However , in an accompanying editorial, Mark E. Bernard, MD, of the University of Kentucky College of Medicine, Lexington, highlighted caveats to the study design and raised two core questions: “Should acute toxic effects be the primary endpoint of a single-group, phase 2 study using hypofractionation with fewer cycles of concurrent chemotherapy? Should the primary endpoint rather have been a cancer control endpoint, such as disease-free survival, overall survival, or local control?”
Still, Dr. Bernard wrote, “This trial does help lay the foundation for future pelvic hypofractionated trials with concurrent chemotherapy, especially for gynecological malignant tumors.”
SOURCE:
The research, led by Won Park, MD, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Republic of Korea, was published in JAMA Oncology.
LIMITATIONS:
The trial is a single-arm study, with a short follow-up time. In the editorial, Bernard listed several limitations, including the fact that patients received fewer cycles of concurrent chemotherapy than what’s typically given in this population.
DISCLOSURES:
No funding or relevant financial relationships were declared.

US Researchers Call for Robust Studies Into Dequalinium, a Bacterial Vaginosis Therapy Common in Europe
Interest is growing in a standard European treatment for bacterial vaginosis (BV).
In a commentary published in JAMA Network Open, researchers and doctors from the Johns Hopkins University School of Medicine in Baltimore and the University of Maryland, Baltimore, urged clinical trials in the United States to determine if dequalinium chloride — an antiseptic that inhibits the growth of bacteria and fungi — is on par with or better than treatments currently available.
Dequalinium has been used throughout Europe for decades and is recommended as an alternative or second-line BV treatment by the World Health Organization; the International Society for the Study of Vulvovaginal Disease; and the Austrian, German, Portuguese, Spanish, and Swiss Societies of Gynecology and Obstetrics. However, the product has not been approved for clinical use in the United States, no trials studying the drug have been registered on ClinicalTrials.gov, and the US Food and Drug Administration has not received an application for approval, according to agency records.
Treatments in the United States for BV include metronidazole and clindamycin that, while effective, have a recurrence rate of up to 60%.
“Current treatments for bacterial vaginosis often fall short, primarily due to frequent recurrences after treatment,” said Rebecca M. Brotman, PhD, MPH, a professor in the Department of Epidemiology and Public Health at the Institute for Genome Sciences at the University of Maryland School of Medicine, and the corresponding author of the commentary.
More than 40% of people with recurrent BV do not receive adequate treatment, according to Caroline M. Mitchell, MD, MPH, director of the Vulvovaginal Disorders Program at Massachusetts General Hospital Vincent Center for Reproductive Biology, Boston, Massachusetts.
“BV is very disruptive to people’s daily lives and causes significant distress,” said Dr. Mitchell, who was not a coauthor of the new article. “Additionally, BV is associated with higher risk for HPV [human papillomavirus] infection, progression of HPV to cervical dysplasia, as well as risk for acquisition of other sexually transmitted infections.”
Dr. Mitchell said she hopes a recent trial from Europe comparing dequalinium chloride to metronidazole spurs researchers to study its efficacy and safety among women in the United States.
“Dequalinium has some antifungal activity, so it might offer a lower chance of yeast infection after treatment, which is important because posttreatment vulvovaginal candidiasis is one of the downsides to conventional antibiotic treatments,” Dr. Mitchell said.
The recent clinical trial included 147 premenopausal women with BV who received 10 mg of dequalinium per day for 6 days or oral metronidazole (500 mg twice daily for 7 days).
Dr. Brotman said any studies in the United States would need to examine long-term recurrence of vaginosis after treatment with dequalinium chloride and its use during pregnancy.
The study was funded by various grants from the National Institutes of Health and the Gates Foundation. Various authors reported receiving royalties from UpToDate outside the submitted work or receiving a donation of sexually transmitted infection testing kits from Hologic for a study outside the submitted work. No other disclosures were reported.

FDA Approves New Antibiotic for Uncomplicated UTIs
The US Food and Drug Administration (FDA) has approved a new treatment for uncomplicated urinary tract infections (UTIs).
The agency on April 24 approved pivmecillinam tablets to treat women aged 18 years or older with UTIs caused by bacteria susceptible to the drug.
The beta-lactam antibiotic already is approved in Europe and has been used for more than 40 years outside of the United States to treat infections, according to the drug’s manufacturer, Utility Therapeutics.
The drug is an aminopenicillin that rapidly converts to mecillinam, according to the company, which is marketing the medication as Pivya.
Pivmecillinam is intended to treat UTIs caused by susceptible isolates of Escherichia coli, Proteus mirabilis, and Staphylococcus saprophyticus.
Researchers studied the treatment in three clinical trials. One study found women who received the new antibiotic were more likely to have resolution of symptoms and a reduction in bacteria in urine compared with placebo (62% vs 10%). Similar results were seen in a trial that used ibuprofen as the comparator (66% vs 22%).
In a third study that assessed two oral antibacterial drugs, 72% of women who received pivmecillinam and 76% who received the other drug achieved resolution of symptoms and a reduction in bacteria, according to the FDA.
The most common side effects of pivmecillinam include nausea and diarrhea.
About half of all women will experience at least one UTI in their lifetime, and the infections are one the top reasons for antibiotic prescriptions, the FDA noted.

One study found women who received the new antibiotic were more likely to have resolution of symptoms and a reduction in bacteria in urine compared with placebo (62% vs 10%). Similar results were seen in a trial that used ibuprofen as the comparator (66% vs 22%).
In a third study that assessed two oral antibacterial drugs, 72% of women who received pivmecillinam and 76% who received the other drug achieved resolution of symptoms and a reduction in bacteria, according to the FDA.
The most common side effects of pivmecillinam include nausea and diarrhea.
About half of all women will experience at least one UTI in their lifetime, and the infections are one the top reasons for antibiotic prescriptions, the FDA noted.

Ovarian Cancer: Another Promising Target for Liquid Biopsy
according to an initial analysis.
The test, under development by Delfi Diagnostics, “looks very sensitive for detecting ovarian cancer early,” said company founder and board member Victor E. Velculescu, MD, PhD, codirector of Cancer Genetics and Epigenetics at Johns Hopkins University, Baltimore.
The assay uses machine learning to integrate cell-free DNA fragment patterns with concentrations of two ovarian cancer biomarkers — CA125 and HE4 — to detect tumors.
While fragmentation patterns are organized in healthy people, they are chaotic in cancer and reveal both its presence and location, said Velculescu who presented the findings at the American Association for Cancer Research annual meeting.
The researchers tested the assay in 134 women with ovarian cancer, 204 women without cancer, and 203 women with benign adnexal masses. The approach identified 69% of stage 1 cancers, 76% of stage 2, 85% of stage 3, and 100% of stage 4 at a specificity of over 99% and an area under the curve (AUC) of 0.97.
The test identified 91% of high-grade serous ovarian cancers — the most common type of ovarian cancer.
The AUC for distinguishing benign masses from cancer was 0.87, with 60% of ovarian cancers detected at a specificity of 95%.
“In the preoperative setting where lower specificity is acceptable, this approach may improve management of adnexal masses,” the investigators said in their abstract.
Dr. Velculescu cautioned that the report “is an initial analysis” and that his team is working on validating the finding on a larger scale in both average and high-risk women.
If validated, the test “could enable population-wide ovarian cancer screening,” he added.
Delfi recently launched a lung cancer screening blood test — FirstLook Lung— that also uses a “fragmentomics” approach to detect tumors. The company is hopeful it will reach the market with a similar test for ovarian cancer, but it’s not a certainty.
With lung cancer, we know screening helps. For ovarian cancer, however, it’s unclear whether this will help or not, said Dr. Velculescu. But based on the study findings, but “we are now optimistic that this could make an impact. We have more work to do.”
This presentation was one of many at the meeting about liquid biopsies using DNA, RNA, and proteins to detect cancer, including a new assay for pancreatic cancer, another cancer that like ovarian cancer is difficult to detect in the early stages.
“This is the future,” said study moderator Roy S. Herbst, MD, PhD, chief of medical oncology at Yale University in New Haven, Connecticut.
He called liquid biopsy “a great advance” in many oncology settings, including cancer screening because finding tumors early offers the best chance at cure.
However, one of the main concerns about rolling out liquid biopsies for wide-scale cancer screening is the possibility that a test will come back positive, but no tumor will be seen on diagnostic imaging, said Herbst. It won’t be clear if the test was a false positive or if the patient has a brewing tumor that can’t be located and treated, a difficult situation for both patients and doctors.
What to do in that situation is “a policy question that the entire country is asking now as liquid biopsies are moving forward,” he said. We are going to have to come together to figure it out and learn how to use these tests.
The work was funded by Delfi Diagnostics, the National Institutes of Health, and others. Dr. Velculescu, in addition to founding Delfi, holds patents on the technology. Dr. Herbst is a consultant, researcher, and/or holds stock in many companies, including AstraZeneca, Pfizer, and Checkpoint Therapeutics.

Surgeon Claims Colleague Made False Board Complaints to Get Him Fired
A longtime Kaiser Permanente surgeon is suing a fellow physician for allegedly submitting false medical board complaints against him in an attempt to get him fired.
Dr. Stalfire, a board-certified ob.gyn., has worked for Kaiser Permanente in western Oregon for more than 20 years, including several years as a regional chief surgical officer.
Dr. Stalfire is accusing Dr. Hsieh of defamation and intentional emotional distress, according to the March 25 lawsuit filed in Marion County Circuit Court. Northwest Permanente P.C., a Kaiser subsidiary, is also named as a defendant.
Dr. Stalfire is asking for $1.2 million in economic damages and $300,000 in noneconomic damages. Dr. Hsieh has not yet responded to the legal complaint.
Dr. Stalfire’s attorney did not respond to a message seeking comment. Dr. Hsieh is representing himself, according to court records. A Kaiser Permanente spokeswoman told this news organization that Kaiser does not comment on pending litigation.
The conflict began in February 2023, after Dr. Stalfire underwent surgery to correct issues stemming from severe injuries when a tree fell on his leg, according to court records.
Dr. Hsieh, a Kaiser ob.gyn., senior physician, and quality assurance lead, allegedly contacted Dr. Stalfire after the surgery and demanded he return to work earlier than medically recommended. Dr. Stalfire claims Dr. Hsieh questioned his retirement plans and his ability to continue working to pressure him into quitting.
Dr. Stalfire reported Dr. Hsieh’s conduct to Kaiser’s human resources department. However, the complaint contends Dr. Hsieh’s actions only escalated after the report was made. According to the complaint, Dr. Hsieh began telling coworkers Dr. Stalfire was “lying” about his injuries. Dr. Hsieh also allegedly contacted administrators and schedulers to ask about Dr. Stalfire’s injuries and suggested that he was not “legitimately recovering from serious injuries.” The complaint claims that Dr. Hsieh told Dr. Stalfire’s colleagues that he was a “con man,” a “criminal,” and “despicable.”
According to Dr. Stalfire’s complaint, in August 2023, Dr. Hsieh submitted numerous anonymous complaints about Dr. Stalfire to the Washington Medical Commission, the Oregon Medical Board, and other governmental agencies. Dr. Stalfire defended himself against the complaints, and they were dismissed. The lawsuit does not specify the nature of the complaints.
Dr. Stalfire later made public record requests for the complaints and discovered Dr. Hsieh had used his deceased mother-in-law’s phone number as his contact information, according to the lawsuit.
Despite multiple reports about Dr. Hsieh’s conduct, Dr. Stalfire claims Kaiser retained Dr. Hsieh as an employee and took no action to prevent him from making false statements about Dr. Stalfire.
He claims Dr. Hsieh’s harassment and Kaiser’s inaction harmed his professional reputation, caused lost work time, and resulted in severe emotional distress that required mental health treatment. The harm caused continues to impact his ability to work, the suit contends.

Minimally Invasive Cytoreductive Approach Comparable to Open Surgery for Ovarian Cancer
This was a finding of a retrospective study presented by Judy Hayek, MD, during an oral abstract session at the Society of Gynecologic Oncology’s Annual Meeting on Women’s Cancer, in San Diego.
Among 2,412 women in the National Cancer Database with tumor-free surgical margins (R0 resections) after interval debulking surgery (IDS), the median overall survival (OS) was 46 months for those who had undergone an open procedure or minimally invasive surgery (MIS) that was converted to an open procedure. In contrast, the median OS was 51 months for patients who underwent laparoscopic or robot-assisted minimally invasive surgery, reported Dr. Hayek, a gynecologic oncology fellow at SUNY Downstate Health Sciences University in Brooklyn, New York.
“R0 resection at the time of interval debulking surgery has similar survival outcomes by minimally invasive surgery versus laparotomy, while R0 resection via laparotomy is associated with higher perioperative mortality. There is no interaction between the extent of surgery and the impact of MIS on survival,” she said during her presentation.
The session included a debate on the pros and cons of minimally invasive vs. open surgery in this population.
Growing Use of MIS
Over the last decade, minimally invasive surgery for interval debulking was shown to be safe and feasible. More recently, two studies using National Cancer Database cohorts showed that survival was similar and perioperative outcomes were better with a minimally invasive approach at the time of IDS for patients with early disease, Dr. Hayek said (Obstet Gynecol 2017 Jul;130(1):71-79; and Gynecol Oncol 2023 May:172:130-137).
Potential limitations of MIS include the absence of haptic feedback compared with open surgery, and the possibility that limited visualization of the surgical field could lead to missed residual disease and subsequent poor outcomes for patients who were presumed to have complete gross resections, she said.
Outcomes Compared
Dr. Hayek and colleagues conducted their study to evaluate survival outcomes after R0 resections by MIS or laparotomy in IDS for patients with advanced epithelial ovarian cancer.
As noted before, they looked at outcomes for 2,412 women with stage IIIC or IV cancers of all histology types who were diagnosed from 2010 through 2019. A total of 624 patients (25.9%) had minimally invasive procedures, and 1,788 (74.1%) had open surgery or MIS that had been converted to open procedures.
Of the minimally invasive procedures, 48.7% were robot-assisted, and the remainder were laparoscopic.
Over the decade of the study, the frequency of minimally invasive surgery steadily increased, from 11.9% of all procedures in 2010 to 36.5% in 2019.
Also as noted, there was no difference in median overall survival, at 46 months for open/converted procedures vs. 51 months for minimally invasive procedures.
As might be expected, the mean length of stay was shorter with the less invasive surgery: 3.3 days compared with 5.3 days with open surgery (P less than .001). In addition, 30-day and 90-day mortality rates were also lower with MIS, at 0.8% and 1.9%, respectively, compared with 1.6% and 3.5% with laparotomy (P = .006 for 30-day mortality, and .003 for 90-day).
There were also no differences in overall survival between the procedure types when the cases were stratified according to extent of surgery. Within the minimally invasive surgery groups there were no differences in median OS for patients whose surgery was performed laparoscopically or with robotic assistance.
The study was limited by a lack of data on either patient-specific tumor burden, neoadjuvant chemotherapy use, progression-free survival, cause of death, or surgical morbidity, Dr. Hayek acknowledged.
MIS Use Debatable: CON
Despite the good outcomes with minimally invasive techniques in this favorable-risk population, critics contend that MIS interval cytoreduction is too risky in the majority of cases.
In the debate portion of the session, Kara Long Roche, MD, an associate attending in the section of ovarian cancer surgery at Memorial Sloan Kettering Cancer Center in New York, argued that the potential for MIS missing residual disease is too great.
“We know from almost every retrospective and prospective study done that the volume of residual disease after debulking, whether primary or interval, is the most important prognostic factor for our patients that we can modify,” she said.
Rather than debating morbidity, mortality, or criteria for resection, “I would argue that the question we need to debate is can MIS interval debulking achieve a completeness of resection, i.e., volume of residual disease?” she said.
Dr. Roche contended that retrospective studies such as that reported by Dr. Hayek cannot adequately answer this question because of selection bias. Patients selected for MIS have better responses to neoadjuvant chemotherapy and more favorable tumor biology; and, therefore, overall survival may not be the optimal endpoint for retrospective studies.
In addition, neoadjuvant chemotherapy does not automatically preclude the need for extensive upper abdominal surgery since almost half of patients who receive neoadjuvant chemotherapy are found to have bulky upper abdominal disease at the time of debulking.
Dr. Roche especially cautioned against what she called the WNL or “We Never Looked” phenomenon, in which patients are found on open surgery and organ mobilization to have disease that was not evident on presurgical imaging.
She acknowledged that for some patients the risks of laparotomy are likely to outweigh the benefit of a radical resection, and stressed that for such patients forgoing surgery or optimizing perioperative care may be more important than the size of the incision.
MIS IDS should be the exception, not the rule. We need prospective data with appropriate endpoints. We need surgical quality control in both arms, and we need to continue to focus on surgical education and training so that our trainees can graduate doing these procedures via any approach,” she concluded.
Debate: PRO
Arguing in favor of MIS for ovarian cancer, J. Alejandro Rauh-Hain, MD, MPH, associate professor of gynecologic oncology at the University of Texas MD Anderson Cancer Center in Houston, told attendees “the only bias I have is that I actually love doing open surgery, but I’m going to try to convince you that there is a potential role for minimally invasive surgery in the future for selected patients with ovarian cancer after neoadjuvant chemotherapy.”
He noted that several studies have convincingly shown that neoadjuvant chemotherapy does not adversely affect oncologic outcomes for patients with advanced-stage ovarian cancer, and decreases perioperative morbidity in patients who receive it, including reductions in serious adverse events, risk of stoma, and 30-day postoperative mortality.
In addition, low use of neoadjuvant chemotherapy is associated with increased risks for 90-day postoperative deaths in both low- and high surgical volume centers in the US, according to unpublished National Cancer Database data.
Dr. Rauh-Hain noted that neoadjuvant chemotherapy use has steadily increased from 2010 through 2020, and added that in 2022, 32% of interval cytoreductive surgeries in the United States were performed with a minimally invasive approach.
To get a better handle on the MIS vs. open-surgery question, Dr. Rauh-Hain and colleagues at MD Anderson and 13 other centers in the United States, Canada, and Europe are currently recruiting patients for the Laparoscopic Cytoreduction After Neoadjuvant Chemotherapy (LANCE) trial. In this phase 3 noninferiority study, patients with stage IIIC-IV ovarian, primary peritoneal, or fallopian tube cancer who have complete or partial responses and CA125 normalization after three or four cycles of neoadjuvant chemotherapy will be randomized to laparotomy or MIS, followed by adjuvant platinum- and taxane-based chemotherapy.
The study by Hayek et al. was internally supported. Dr. Hayek and Dr. Roche reported having no conflicts of interest. Dr. Rauh-Hain disclosed financial relationships with Guidepoint Consulting, and the Schlesinger Group.

He noted that several studies have convincingly shown that neoadjuvant chemotherapy does not adversely affect oncologic outcomes for patients with advanced-stage ovarian cancer, and decreases perioperative morbidity in patients who receive it, including reductions in serious adverse events, risk of stoma, and 30-day postoperative mortality.
In addition, low use of neoadjuvant chemotherapy is associated with increased risks for 90-day postoperative deaths in both low- and high surgical volume centers in the US, according to unpublished National Cancer Database data.
Dr. Rauh-Hain noted that neoadjuvant chemotherapy use has steadily increased from 2010 through 2020, and added that in 2022, 32% of interval cytoreductive surgeries in the United States were performed with a minimally invasive approach.
To get a better handle on the MIS vs. open-surgery question, Dr. Rauh-Hain and colleagues at MD Anderson and 13 other centers in the United States, Canada, and Europe are currently recruiting patients for the Laparoscopic Cytoreduction After Neoadjuvant Chemotherapy (LANCE) trial. In this phase 3 noninferiority study, patients with stage IIIC-IV ovarian, primary peritoneal, or fallopian tube cancer who have complete or partial responses and CA125 normalization after three or four cycles of neoadjuvant chemotherapy will be randomized to laparotomy or MIS, followed by adjuvant platinum- and taxane-based chemotherapy.
The study by Hayek et al. was internally supported. Dr. Hayek and Dr. Roche reported having no conflicts of interest. Dr. Rauh-Hain disclosed financial relationships with Guidepoint Consulting, and the Schlesinger Group.
This was a finding of a retrospective study presented by Judy Hayek, MD, during an oral abstract session at the Society of Gynecologic Oncology’s Annual Meeting on Women’s Cancer, in San Diego.
Among 2,412 women in the National Cancer Database with tumor-free surgical margins (R0 resections) after interval debulking surgery (IDS), the median overall survival (OS) was 46 months for those who had undergone an open procedure or minimally invasive surgery (MIS) that was converted to an open procedure. In contrast, the median OS was 51 months for patients who underwent laparoscopic or robot-assisted minimally invasive surgery, reported Dr. Hayek, a gynecologic oncology fellow at SUNY Downstate Health Sciences University in Brooklyn, New York.
“R0 resection at the time of interval debulking surgery has similar survival outcomes by minimally invasive surgery versus laparotomy, while R0 resection via laparotomy is associated with higher perioperative mortality. There is no interaction between the extent of surgery and the impact of MIS on survival,” she said during her presentation.
The session included a debate on the pros and cons of minimally invasive vs. open surgery in this population.
Growing Use of MIS
Over the last decade, minimally invasive surgery for interval debulking was shown to be safe and feasible. More recently, two studies using National Cancer Database cohorts showed that survival was similar and perioperative outcomes were better with a minimally invasive approach at the time of IDS for patients with early disease, Dr. Hayek said (Obstet Gynecol 2017 Jul;130(1):71-79; and Gynecol Oncol 2023 May:172:130-137).
Potential limitations of MIS include the absence of haptic feedback compared with open surgery, and the possibility that limited visualization of the surgical field could lead to missed residual disease and subsequent poor outcomes for patients who were presumed to have complete gross resections, she said.
Outcomes Compared
Dr. Hayek and colleagues conducted their study to evaluate survival outcomes after R0 resections by MIS or laparotomy in IDS for patients with advanced epithelial ovarian cancer.
As noted before, they looked at outcomes for 2,412 women with stage IIIC or IV cancers of all histology types who were diagnosed from 2010 through 2019. A total of 624 patients (25.9%) had minimally invasive procedures, and 1,788 (74.1%) had open surgery or MIS that had been converted to open procedures.
Of the minimally invasive procedures, 48.7% were robot-assisted, and the remainder were laparoscopic.
Over the decade of the study, the frequency of minimally invasive surgery steadily increased, from 11.9% of all procedures in 2010 to 36.5% in 2019.
Also as noted, there was no difference in median overall survival, at 46 months for open/converted procedures vs. 51 months for minimally invasive procedures.
As might be expected, the mean length of stay was shorter with the less invasive surgery: 3.3 days compared with 5.3 days with open surgery (P less than .001). In addition, 30-day and 90-day mortality rates were also lower with MIS, at 0.8% and 1.9%, respectively, compared with 1.6% and 3.5% with laparotomy (P = .006 for 30-day mortality, and .003 for 90-day).
There were also no differences in overall survival between the procedure types when the cases were stratified according to extent of surgery. Within the minimally invasive surgery groups there were no differences in median OS for patients whose surgery was performed laparoscopically or with robotic assistance.
The study was limited by a lack of data on either patient-specific tumor burden, neoadjuvant chemotherapy use, progression-free survival, cause of death, or surgical morbidity, Dr. Hayek acknowledged.
MIS Use Debatable: CON
Despite the good outcomes with minimally invasive techniques in this favorable-risk population, critics contend that MIS interval cytoreduction is too risky in the majority of cases.
In the debate portion of the session, Kara Long Roche, MD, an associate attending in the section of ovarian cancer surgery at Memorial Sloan Kettering Cancer Center in New York, argued that the potential for MIS missing residual disease is too great.
“We know from almost every retrospective and prospective study done that the volume of residual disease after debulking, whether primary or interval, is the most important prognostic factor for our patients that we can modify,” she said.
Rather than debating morbidity, mortality, or criteria for resection, “I would argue that the question we need to debate is can MIS interval debulking achieve a completeness of resection, i.e., volume of residual disease?” she said.
Dr. Roche contended that retrospective studies such as that reported by Dr. Hayek cannot adequately answer this question because of selection bias. Patients selected for MIS have better responses to neoadjuvant chemotherapy and more favorable tumor biology; and, therefore, overall survival may not be the optimal endpoint for retrospective studies.
In addition, neoadjuvant chemotherapy does not automatically preclude the need for extensive upper abdominal surgery since almost half of patients who receive neoadjuvant chemotherapy are found to have bulky upper abdominal disease at the time of debulking.
Dr. Roche especially cautioned against what she called the WNL or “We Never Looked” phenomenon, in which patients are found on open surgery and organ mobilization to have disease that was not evident on presurgical imaging.
She acknowledged that for some patients the risks of laparotomy are likely to outweigh the benefit of a radical resection, and stressed that for such patients forgoing surgery or optimizing perioperative care may be more important than the size of the incision.
MIS IDS should be the exception, not the rule. We need prospective data with appropriate endpoints. We need surgical quality control in both arms, and we need to continue to focus on surgical education and training so that our trainees can graduate doing these procedures via any approach,” she concluded.

Therapeutic HPV16 vaccine clears virus in most patients with CIN
The vaccine, pNGVL4a-CRTE6E7L2, also showed signs of efficacy in patients living with HIV, reported Kimberly Lynn Levinson, MD, MPH, associate professor of obstetrics and gynecology at Johns Hopkins Medicine in Baltimore.
“We demonstrated a 78% rate of clearance for both histologic regression and HPV16, with some clearance of other HPV types,” she said in an oral abstract presentation at the Society of Gynecologic Oncology’s Annual Meeting on Women’s Cancer, held in San Diego.
Further evaluation of the vaccine in vulvar, vaginal, and other tissue types is required, and evaluation of immune response at the local and systemic is ongoing, Dr. Levinson said.
In contrast to HPV16 prophylactic vaccines, which form an antibody-specific response to HPV, therapeutic vaccines elicit a cell-mediated immunity, primarily focusing on the virus’ E6 and E7 proteins.
There are currently only three Food and Drug Administration–approved therapeutic vaccines for cancer, but none are as yet approved for treatment of gynecologic malignancies.
According to the US National Institutes of Health, there are multiple therapeutic HPV vaccines in development using either vector-based, peptide and protein-based, or nucleic-acid based approaches, or whole cell (dendritic cell) approaches.
Current Study
Dr. Levinson noted that “DNA vaccines are both well tolerated and simple to produce, and the addition of calreticulin enhances immune response.”
The investigational vaccine is delivered via an electoporation device (TriGrid delivery system) that stimulates muscle at the injection site to produce an enhanced immune response.
In preclinical studies the device was associated with an enhanced immune response compared with standard intramuscular injection. The enhance immune effect persisted despite CD4 T cell depletion.
The investigators conducted a phase 1 dose-escalation study, administering the vaccine to two separate cohorts: women without HIV who had HPV16-positive cervical dysplasia (CIN 2/3) and women living with HIV with HPV16-positive cervical or vulvovaginal dysplasia (CIN 2/3, VIN 2/3 or VAIN 2/3).
The vaccine was delivered at weeks 0, 4, and 8, at doses of 0.3 mg, 1.0 mg, or 3.0 mg. At week 12, all patients underwent site-specific biopsy to verify non-progression.
At 6 months, the patients then underwent definitive treatment with either loop electro excision or vulvar/vaginal excision. At 12 months, all patients had standard evaluations with biopsies.
Dr. Levinson reported results for the first 14 women enrolled, 10 of whom were HIV-negative and 4 of whom were HIV-positive.
Of nine women in the HIV-negative arm who had completed 6-month visits and were evaluable, two had HPV16 clearance by 2-month follow-up, and seven had clearance at 6 months. Other HPV subtypes cleared in two of five patients at 3 months and in three of five at 6 months.
In addition, seven of nine patients in this arm had histologic regression at 6 months.
In the HIV-positive arm, the two patients with CIN had no HPV16 clearance at 3 months, but both had clearance at 16 months. The vaccine did not clear other HPV subtypes in these patients, however.
Of the two women in this arm who had VIN, one had HPV16 clearance and histologic regression at 6 months. The other patient had neither viral clearance nor histologic regression.
All participants tolerated each vaccine well. Adverse events were all grade 1 in severity and resolved within 4 weeks. The most common event was tenderness at the injection site. There were also three cases of mild headache, two cases of drowsiness, and one of nausea.
What’s Next?
In the question-and-answer session following the presentation, Ronald D. Alvarez, MD, MBA, chairman and clinical service chief of obstetrics and gynecology at Vanderbilt University Medical Center in Nashville, Tennessee, asked Dr. Levinson how the vaccine development will proceed.
“Obviously, you have more data to collect and analyze, but how are you going to move forward with what looks like equal efficacy between the 1 milligram and the 3 milligram doses? Are you just going to go with the maximum tolerated dose, or consider a lower dose if it shows equal efficacy in terms of histologic regression as well as HPV clearance?” he asked.
“This is something we’re very interested in, and we do plan for the dose-expansion phase to go with the higher dose,” Dr. Levinson replied. “We need to evaluate it further and we may need to do further randomization between the medium dose and the highest dose to determine if there are differences both with systemic and local responses.”
Robert DeBernardo, MD, section head of obstetrics and gynecology and the Women’s Health Institute at the Cleveland Clinic, asked whether Dr. Levinson and colleagues were considering evaluating the vaccine in transplant recipients, “because we have a lot of persistent HPV in that subgroup.”
Dr. Levinson said that one of the dose-expansion cohorts for further study is a population of patients scheduled for transplantation.
“What we’re interested in is looking at whether we can ‘cure’ HPV prior to transplantation, and we think that’s going to be the best way to show that this vaccine potentially eliminates the virus, because if we can eliminate the virus and then take a population that’s going to be immunodeficient, then that would show that there’s no reactivation of the virus,” she said.
The study is supported by the National Institutes of Health. Dr. Levinson, Dr. Alvarez, and Dr. DeBernardo had no conflicts of interest to report.
