Can US “pattern recognition” of classic adnexal lesions reduce surgery, and even referrals for other imaging, in average-risk women?
Gupta A, Jha P, Baran TM, et al. Ovarian cancer detection in average-risk women: classic- versus nonclassic-appearing adnexal lesions at US. Radiology. 2022;212338. doi: 10.1148/radiol.212338.
Expert commentary
Gupta and colleagues conducted a multicenter, retrospective review of 970 adnexal lesions among 878 women—75% were premenopausal and 25% were postmenopausal.
Imaging details
The lesions were characterized by pattern recognition as “classic” (simple cysts, endometriomas, hemorrhagic cysts, or dermoids) or “nonclassic.” Out of 673 classic lesions, there were 4 malignancies (0.6%), of which 1 was an endometrioma and 3 were classified as simple cysts. However, out of 297 nonclassic lesions (multilocular, unilocular with solid areas or wall irregularity, or mostly solid), 32% (33/103) were malignant when vascularity was present, while 8% (16/184) were malignant when no intralesional vascularity was appreciated.
The authors pointed out that, especially because their study was retrospective, there was no standardization of scan technique or equipment employed. However, this point adds credibility to the “real world” nature of such imaging.
Other data corroborate findings
Other studies have looked at pattern recognition in efforts to optimize a conservative approach to benign masses and referral to oncology for suspected malignant masses, as described above. This was the main cornerstone of the International Consensus Conference,2 which also identified next steps for indeterminate masses, including evidence-based risk assessment algorithms and referral (to an expert imager or gynecologic oncologist). A multicenter trial in Europe3 found that ultrasound experience substantially impacts on diagnostic performance when adnexal masses are classified using pattern recognition. This occurred in a stepwise fashion with increasing accuracy directly related to the level of expertise. Shetty and colleagues4 found that pattern recognition performed better than the risk of malignancy index (sensitivities of 95% and 79%, respectively). ●
While the concept of pattern recognition for some “classic” benign ovarian masses has been around for some time, this is the first time a large United States–based study (albeit retrospective) has corroborated that when ultrasonography reveals a classic, or “almost certainly benign” finding, patients can be reassured that the lesion is benign, thereby avoiding extensive further workup. When a lesion is “nonclassic” in appearance and without any blood flow, further imaging with follow-up magnetic resonance imaging or repeat ultrasound could be considered. In women with a nonclassic lesion with blood flow, particularly in older women, referral to a gynecologic oncologic surgeon will help ensure expeditious treatment of possible ovarian cancer.

Relugolix combo eases a long-neglected fibroid symptom: Pain
Combination therapy with relugolix (Orgovyx, Relumina), a gonadotropin-releasing hormone antagonist, significantly reduced the pain of uterine fibroids, an undertreated aspect of this disease.
In pooled results from the multicenter randomized placebo-controlled LIBERTY 1 and 2 trials, relugolix combination therapy (CT) with the progestin norethindrone (Aygestin, Camila) markedly decreased both menstrual and nonmenstrual fibroid pain, as well as heavy bleeding and other symptoms of leiomyomas. This hormone-dependent condition occurs in 70%-80% of premenopausal women.
“Historically, studies of uterine fibroids have not asked about pain, so one of strengths of these studies is that they asked women to rate their pain and found a substantial proportion listed pain as a symptom,” lead author Elizabeth A. Stewart, MD, director of reproductive endocrinology at the Mayo Clinic in Rochester, Minn., said in an interview.
The combination was effective against all categories of leiomyoma symptoms, she said, and adverse events were few.
Bleeding has been the main focus of studies of leiomyoma therapies, while chronic pain has been largely neglected, said James H. Segars Jr., MD, director of the division of reproductive science and women’s health research at Johns Hopkins Medicine in Baltimore, who was not involved in the studies. Across both of the LIBERTY trials, involving 509 women randomized during the period April 2017 to December 2018, more than half overall (54.4%) met their pain reduction goals in a subpopulation analysis. Pain reduction was a secondary outcome of the trials, with bleeding reduction the primary endpoint. Other fibroid symptoms are abdominal bloating and pressure.
“The consistent and significant reduction in measures of pain with relugolix-CT observed in the LIBERTY program is clinically meaningful, patient-relevant, and together with an improvement of heavy menstrual bleeding and other uterine leiomyoma–associated symptoms, is likely to have a substantial effect on the life of women with symptomatic uterine leiomyomas,” Dr. Stewart and colleagues wrote. Their report was published online in Obstetrics & Gynecology.
Dr. Segars concurred. “This study is important because sometimes the only fibroid symptom women have is pain. If we ignore that, we miss a lot of women who have pain but no bleeding.”
The study
The premenopausal participants had a mean age of just over 42 years (range, 18-50) and were enrolled from North and South America, Europe, and Africa. All reported leiomyoma-associated heavy menstrual bleeding of 80 mL or greater per cycle for two cycles, or 160 mL or greater during one cycle.
In both arms, the mean body mass index was 32 kg/m2, while menstrual blood loss volume was 245.4 (± 186.4) mL in the relugolix-CT and 207.4 (± 114.3) mL in the placebo group.
Pain was a frequent symptom, with approximately 70% in the intervention group and 74% in the placebo group reporting fibroid pain at baseline.
Women were randomized 1:1:1 to receive:
- Relugolix-CT (relugolix 40 mg, estradiol 1 mg, norethindrone acetate 0.5 mg)
- Delayed relugolix-CT (relugolix 40 mg monotherapy followed by relugolix-CT, each for 12 weeks)
- Placebo, taken orally once daily for 24 weeks
The therapy was well tolerated and adverse events were low.
The subpopulation analysis found that over the study period, the proportion of women achieving minimal to no pain (level 0 to 1) during the last 35 days of treatment was notably higher in the relugolix-CT arm than in the placebo arm: 45.2% (95% confidence interval [CI], 36.4%-54.3%) versus 13.9% (95% CI, 8.8%-20.5%) in the placebo group (nominal P = .001).
Moreover, the proportions of women with minimal to no pain during both menstrual days and nonmenstrual days were significantly higher with relugolix-CT: 65.0% (95% CI, 55.6%-73.5%) and 44.6% (95% CI, 32.3%-7.5%), respectively, compared with placebo: 19.3% (95% CI 13.2%–26.7%, nominal P = 001), and 21.6% (95% CI, 12.9%-32.7%, nominal P = 004), respectively.
Studies of relugolix monotherapy in Japanese women with uterine leiomyomas have demonstrated reductions in pain.
“Significantly, this combination therapy allows women to be treated over 2 years and to take the oral tablet themselves, unlike Lupron [leuprolide], which is injected and can only be taken for a couple of months because of bone loss,” Dr. Segars said. And the add-back component of combination therapy prevents the adverse symptoms of a hypoestrogenic state.
“The pain of fibroids is chronic, and the longer treatment allows time for the pain fibers to revert to a normal state,” he explained. “The pain pathways get etched into the nerves and it takes time to revert.”
He noted that the LIBERTY trials showed a slight downward trend in pain continuing after 24 weeks of treatment. Other studies of similar hormonal treatments have shown a reduction in the size of fibroids, which can be as large as a tennis ball.
As in endometriosis, leiomyomas are associated with elevated circulating cytokines and a systemic proinflammatory state. In endometriosis, this milieu is linked to the risk of inflammatory arthritis, fibromyalgia, lupus, and cardiovascular disease, Dr. Segars said. “If we did a deeper dive, we might find the same associations for fibroids.” Apart from chronic depression and fatigue, fibroids are linked to downstream pregnancy complications and poor outcomes such as miscarriage and preterm birth, he said.
“There remains a high unmet need for effective treatments, especially nonsurgical interventions, for women with uterine leiomyomas,” the authors wrote. Dr. Stewart added that “it would be helpful to learn more about how relugolix and other drugs in its class work in fibroids. No category of symptoms has been unresponsive to these medications – they are powerful drugs to help women with uterine fibroids.” She noted that relugolix-CT has already been approved outside the United States for symptoms beyond heavy menstrual bleeding.
Future research should focus on developing a therapy that does not interfere with fertility, Dr. Segars said. “We need a treatment that will allow women to get pregnant on it.”
Myovant Sciences GmbH sponsored LIBERTY 1 and 2 and oversaw all aspects of the studies. Dr. Stewart has provided consulting services to Myovant, Bayer, AbbVie, and ObsEva. She has received royalties from UpToDate and fees from Med Learning Group, Med-IQ, Medscape, Peer View, and PER, as well as honoraria from the American College of Obstetricians and Gynecologists and Massachusetts Medical Society. She holds a patent for methods and compounds for treatment of abnormal uterine bleeding. Dr. Segars has consulted for Bayer and Organon. Several coauthors reported similar financial relationships with private-sector entities and two coauthors are employees of Myovant.

FDA approves oteseconazole for chronic yeast infections
The Food and Drug Administration has approved oteseconazole capsules (Vivjoa), an azole antifungal agent, for the prevention of recurrent yeast infections in women who are not of reproductive potential.
Oteseconazole inhibits CYP51, an enzyme fungi require to preserve the integrity of their cell walls and to grow properly, according to Mycovia, the drug’s manufacturer. It is the first FDA-approved product for the treatment of recurrent vulvovaginal candidiasis (RVVC).
Recurrent vulvovaginal candidiasis, or chronic yeast infection, affects an estimated 138 million women worldwide annually. The condition is defined as three or more symptomatic acute episodes of yeast infection within a 12-month period. The primary symptoms of RVVC include vaginal itching, burning, irritation, and inflammation. Some patients may also experience abnormal vaginal discharge and pain during sex or urination.
“A medicine with Vivjoa’s sustained efficacy combined with the clinical safety profile has been long needed, as until now, physicians and their patients have had no FDA-approved medications for RVVC,” Stephen Brand, PhD, chief development officer of Mycovia, said in a statement. “We are excited to be the first to offer a medication designed specifically for RVVC, a challenging and chronic condition that is expected to increase in prevalence over the next decade.”
Approval for oteseconazole was based on results of three phase 3 trials involving 875 patients at 232 sites across 11 countries. In the U.S.-only ultraVIOLET trial, 89.7% of women with RVVC who received oteseconazole cleared their initial yeast infection and did not experience a recurrence during the 50-week maintenance period, compared with 57.1% of those who received fluconazole (Diflucan) followed by placebo (P < .001), according to Mycovia.
The most common side effects reported in phase 3 clinical studies were headache (7.4%) and nausea (3.6%), the company said. Patients with a hypersensitivity to oteseconazole should not take the drug, nor should those who are of reproductive potential, pregnant, or lactating.
Mycovia said it plans to launch the drug in the second quarter of 2022.

The Food and Drug Administration has approved oteseconazole capsules (Vivjoa), an azole antifungal agent, for the prevention of recurrent yeast infections in women who are not of reproductive potential.
Oteseconazole inhibits CYP51, an enzyme fungi require to preserve the integrity of their cell walls and to grow properly, according to Mycovia, the drug’s manufacturer. It is the first FDA-approved product for the treatment of recurrent vulvovaginal candidiasis (RVVC).
Recurrent vulvovaginal candidiasis, or chronic yeast infection, affects an estimated 138 million women worldwide annually. The condition is defined as three or more symptomatic acute episodes of yeast infection within a 12-month period. The primary symptoms of RVVC include vaginal itching, burning, irritation, and inflammation. Some patients may also experience abnormal vaginal discharge and pain during sex or urination.

Childhood abuse may increase risk of MS in women
, according to the first prospective cohort study of its kind.
More research is needed to uncover underlying mechanisms of action, according to lead author Karine Eid, MD, a PhD candidate at Haukeland University Hospital, Bergen, Norway, and colleagues.
“Trauma and stressful life events have been associated with an increased risk of autoimmune disorders,” the investigators wrote in the Journal Of Neurology, Neurosurgery, & Psychiatry. “Whether adverse events in childhood can have an impact on MS susceptibility is not known.”
The present study recruited participants from the Norwegian Mother, Father and Child cohort, a population consisting of Norwegian women who were pregnant from 1999 to 2008. Of the 77,997 participating women, 14,477 reported emotional, sexual, and/or physical abuse in childhood, while the remaining 63,520 women reported no abuse. After a mean follow-up of 13 years, 300 women were diagnosed with MS, among whom 24% reported a history of childhood abuse, compared with 19% among women who did not develop MS.
To look for associations between childhood abuse and risk of MS, the investigators used a Cox model adjusted for confounders and mediators, including smoking, obesity, adult socioeconomic factors, and childhood social status. The model revealed that emotional abuse increased the risk of MS by 40% (hazard ratio [HR] 1.40; 95% confidence interval [CI], 1.03-1.90), and sexual abuse increased the risk of MS by 65% (HR 1.65; 95% CI, 1.13-2.39).
Although physical abuse alone did not significantly increase risk of MS (HR 1.31; 95% CI, 0.83-2.06), it did contribute to a dose-response relationship when women were exposed to more than one type of childhood abuse. Women exposed to two out of three abuse categories had a 66% increased risk of MS (HR 1.66; 95% CI, 1.04-2.67), whereas women exposed to all three types of abuse had the highest risk of MS, at 93% (HR 1.93; 95% CI, 1.02-3.67).
Dr. Eid and colleagues noted that their findings are supported by previous retrospective research, and discussed possible mechanisms of action.
“The increased risk of MS after exposure to childhood sexual and emotional abuse may have a biological explanation,” they wrote. “Childhood abuse can cause dysregulation of the hypothalamic-pituitary-adrenal axis, lead to oxidative stress, and induce a proinflammatory state decades into adulthood. Psychological stress has been shown to disrupt the blood-brain barrier and cause epigenetic changes that may increase the risk of neurodegenerative disorders, including MS.
“The underlying mechanisms behind this association should be investigated further,” they concluded.
Study findings should guide interventions
Commenting on the research, Ruth Ann Marrie, MD, PhD, professor of medicine and community health sciences and director of the multiple sclerosis clinic at Max Rady College of Medicine, Rady Faculty of Health Sciences, University of Manitoba, Winnipeg, said that the present study “has several strengths compared to prior studies – including that it is prospective and the sample size.”
Dr. Marrie, who was not involved in the study, advised clinicians in the field to take note of the findings, as patients with a history of abuse may need unique interventions.
“Providers need to recognize the higher prevalence of childhood maltreatment in people with MS,” Dr. Marrie said in an interview. “These findings dovetail with others that suggest that adverse childhood experiences are associated with increased mental health concerns and pain catastrophizing in people with MS. Affected individuals may benefit from additional psychological supports and trauma-informed care.”
Tiffany Joy Braley, MD, associate professor of neurology, and Carri Polick, RN and PhD candidate at the school of nursing, University of Michigan, Ann Arbor, who published a case report last year highlighting the importance of evaluating stress exposure in MS, suggested that the findings should guide interventions at both a system and patient level.
“Although a cause-and-effect relationship cannot be established by the current study, these and related findings should be considered in the context of system level and policy interventions that address links between environment and health care disparities,” they said in a joint, written comment. “Given recent impetus to provide trauma-informed health care, these data could be particularly informative in neurological conditions which are associated with high mental health comorbidity. Traumatic stress screening practices could lead to referrals for appropriate support services and more personalized health care.”
While several mechanisms have been proposed to explain the link between traumatic stress and MS, more work is needed in this area, they added.
This knowledge gap was acknowledged by Dr. Marrie.
“Our understanding of the etiology of MS remains incomplete,” Dr. Marrie said. “We still need a better understanding of mechanisms by which adverse childhood experiences lead to MS, how they interact with other risk factors for MS (beyond smoking and obesity), and whether there are any interventions that can mitigate the risk of developing MS that is associated with adverse childhood experiences.”
The investigators disclosed relationships with Novartis, Biogen, Merck, and others. Dr. Marrie receives research support from the Canadian Institutes of Health Research, the National Multiple Sclerosis Society, MS Society of Canada, the Consortium of Multiple Sclerosis Centers, Crohn’s and Colitis Canada, Research Manitoba, and the Arthritis Society; she has no pharmaceutical support. Dr. Braley and Ms. Polick reported no conflicts of interest.

Tebipenem pivoxil hydrobromide offers oral option for complex UTIs
“No new oral antibiotic alternative has emerged to treat these conditions in more than 25 years,” corresponding author Angela K. Talley, MD, said in an interview. The new research was published in the New England Journal of Medicine.
Patients with complicated urinary tract infection (cUTI), including acute pyelonephritis (AP), are often hospitalized and treated with intravenous therapy because of the lack of oral options, especially in cases of antibiotic-resistant pathogens, explained Dr. Talley, of Spero Therapeutics.
In their new phase 3, double-blind randomized trial, the researchers evaluated the safety and effectiveness of oral TBP-PI-HBr, compared with intravenous ertapenem in hospitalized patients with cUTIs or AP. Oral tebipenem is an investigational carbapenem with demonstrated activity against uropathogenic Enterobacterales, and it has shown effectiveness in animal models, the researchers noted in their paper.
Methods and results
The researchers randomized 1,372 adult patients. The microbiologic intent-to-treat population included 449 patients who received TBP-PI-HBr (600 mg every 8 hours) and 419 who received ertapenem (1 g every 24 hours) for 7-10 days or up to 14 days for patients with bacteremia.
The primary endpoint was a composite of clinical cure and favorable microbiologic response, assessed at a test-of-cure visit on day 19. Clinical cure was defined as “complete resolution or clinically significant alleviation of baseline signs and symptoms of complicated urinary tract infection or acute pyelonephritis and no new symptoms, such that no further antimicrobial therapy was warranted,” the researchers wrote. Microbiologic response was defined as a reduction to less than 103 CFU per milliliter in uropathogen levels from baseline at day 19.
Overall, the clinical response occurred in 58.8% of patients who received TBP-PI-HBr and 61.6% of those who received ertapenem at the test-of-cure visit.
Clinical cure rates were similar in the TBP-PI-HBr and ertapenem groups (93.1% vs. 93.6%) at the test-of-cure visit.
Both treatment groups showed similar responses to Enterobacterales pathogens at the test-of-cure visit (62.7% for TBP-PI-HBr and 65.2% for ertapenem).
Among patients with bacteremia at baseline, overall response rates were 72.3% and 66.0% for TBP-PI-HBr and ertapenem, respectively, at the test-of-cure visit, and 93.6% and 96.2%, respectively, at the end-of-treatment visit on or around day 25.
The overall incidence of adverse events was approximately 26% in both treatment groups. Most adverse events were mild or moderate in severity and did not limit treatment, the researchers wrote.
The mean age of the patients was 58.1 years; 46.1% were aged 65 and older, and 11.5% had bacteremia at baseline.
The study findings were limited by several factors, including the mandated 7- to 10-day course of antibiotics, which may not reflect the standard of care in other settings in the United States. The study’s trial sites were located in the United States, South Africa, and Europe. The study population was primarily White and from Central and Eastern Europe. Other limitations included the randomization of patients before confirming the baseline pathogen, although this was done to limit potential confounding from previous antibiotics, the researchers noted.
Safety and efficacy support application for approval
“To our knowledge, this is the first head-to-head evaluation of an IV vs. an oral drug for the treatment of cUTI and acute pyelonephritis,” Dr. Talley said in an interview.
“The findings demonstrate that almost all patients in the study achieved complete resolution of the signs and symptoms of their infection,” she said.
TBP-PI-HBr has not been approved by the Food and Drug Administration, but a new drug application that included data from the current study was submitted to the FDA and is currently under review, Dr. Talley noted.
As for additional research, the current study was conducted in hospitalized patients, and the use of TBP-PI-HBr in the outpatient setting has not yet been evaluated, she said.
Approval and use of oral carbapenem will change practice
The current study is very important because it provides a viable and effective alternative form of antibiotic delivery for the patients with complicated UTI, Noel N. Deep, MD, emphasized in an interview.
“Currently these patients have to be treated with IV carbapenem antibiotics either in a hospital or through a home health nurse,” Dr. Deep, a general internist in group practice in Antigo, Wisc., explained.
Current IV strategies also carry the inherent risk associated with the insertion of an IV catheter that is left in place for several days or replaced periodically. “The oral antibiotic eliminates these risks and higher health care costs and provides a safer and equally efficacious option,” Dr. Deep said.
In the current study, “I was definitely surprised at the effectiveness of the oral carbapenem,” Dr. Deep said. “I am absolutely delighted with this new treatment option that physicians can now add to their armamentarium [assuming FDA approval] as we provide care to our patients,” he said.
If approved, TBP-PI-HBr will definitely change the treatment spectrum for the multidrug-resistant bacterial UTIs, said Dr. Deep. “Carbapenems have continued to be effective and low antibiotic resistance to carbapenems has been recorded.”
As for additional research, “I would like to see studies done in other ethnicities and different countries to ascertain the effectiveness of this antibiotic in those populations and against other bacterial strains with potentially different resistance mechanisms,” Dr. Deep said.
The study was supported by Spero Therapeutics and the Department of Health and Human Services. Lead author Paul B. Eckburg, MD, of Stanford (Calif.) University, and Dr. Talley are employees of Spero Therapeutics. Dr. Deep had no financial conflicts to disclose, but serves on the editorial advisory board of Internal Medicine News.

The researchers randomized 1,372 adult patients. The microbiologic intent-to-treat population included 449 patients who received TBP-PI-HBr (600 mg every 8 hours) and 419 who received ertapenem (1 g every 24 hours) for 7-10 days or up to 14 days for patients with bacteremia.
The primary endpoint was a composite of clinical cure and favorable microbiologic response, assessed at a test-of-cure visit on day 19. Clinical cure was defined as “complete resolution or clinically significant alleviation of baseline signs and symptoms of complicated urinary tract infection or acute pyelonephritis and no new symptoms, such that no further antimicrobial therapy was warranted,” the researchers wrote. Microbiologic response was defined as a reduction to less than 103 CFU per milliliter in uropathogen levels from baseline at day 19.
Overall, the clinical response occurred in 58.8% of patients who received TBP-PI-HBr and 61.6% of those who received ertapenem at the test-of-cure visit.
Clinical cure rates were similar in the TBP-PI-HBr and ertapenem groups (93.1% vs. 93.6%) at the test-of-cure visit.
Both treatment groups showed similar responses to Enterobacterales pathogens at the test-of-cure visit (62.7% for TBP-PI-HBr and 65.2% for ertapenem).
Among patients with bacteremia at baseline, overall response rates were 72.3% and 66.0% for TBP-PI-HBr and ertapenem, respectively, at the test-of-cure visit, and 93.6% and 96.2%, respectively, at the end-of-treatment visit on or around day 25.
The overall incidence of adverse events was approximately 26% in both treatment groups. Most adverse events were mild or moderate in severity and did not limit treatment, the researchers wrote.
The mean age of the patients was 58.1 years; 46.1% were aged 65 and older, and 11.5% had bacteremia at baseline.
The study findings were limited by several factors, including the mandated 7- to 10-day course of antibiotics, which may not reflect the standard of care in other settings in the United States. The study’s trial sites were located in the United States, South Africa, and Europe. The study population was primarily White and from Central and Eastern Europe. Other limitations included the randomization of patients before confirming the baseline pathogen, although this was done to limit potential confounding from previous antibiotics, the researchers noted.
Safety and efficacy support application for approval
“To our knowledge, this is the first head-to-head evaluation of an IV vs. an oral drug for the treatment of cUTI and acute pyelonephritis,” Dr. Talley said in an interview.
“The findings demonstrate that almost all patients in the study achieved complete resolution of the signs and symptoms of their infection,” she said.
TBP-PI-HBr has not been approved by the Food and Drug Administration, but a new drug application that included data from the current study was submitted to the FDA and is currently under review, Dr. Talley noted.
As for additional research, the current study was conducted in hospitalized patients, and the use of TBP-PI-HBr in the outpatient setting has not yet been evaluated, she said.
Approval and use of oral carbapenem will change practice
The current study is very important because it provides a viable and effective alternative form of antibiotic delivery for the patients with complicated UTI, Noel N. Deep, MD, emphasized in an interview.
“Currently these patients have to be treated with IV carbapenem antibiotics either in a hospital or through a home health nurse,” Dr. Deep, a general internist in group practice in Antigo, Wisc., explained.
Current IV strategies also carry the inherent risk associated with the insertion of an IV catheter that is left in place for several days or replaced periodically. “The oral antibiotic eliminates these risks and higher health care costs and provides a safer and equally efficacious option,” Dr. Deep said.
In the current study, “I was definitely surprised at the effectiveness of the oral carbapenem,” Dr. Deep said. “I am absolutely delighted with this new treatment option that physicians can now add to their armamentarium [assuming FDA approval] as we provide care to our patients,” he said.
If approved, TBP-PI-HBr will definitely change the treatment spectrum for the multidrug-resistant bacterial UTIs, said Dr. Deep. “Carbapenems have continued to be effective and low antibiotic resistance to carbapenems has been recorded.”
As for additional research, “I would like to see studies done in other ethnicities and different countries to ascertain the effectiveness of this antibiotic in those populations and against other bacterial strains with potentially different resistance mechanisms,” Dr. Deep said.
The study was supported by Spero Therapeutics and the Department of Health and Human Services. Lead author Paul B. Eckburg, MD, of Stanford (Calif.) University, and Dr. Talley are employees of Spero Therapeutics. Dr. Deep had no financial conflicts to disclose, but serves on the editorial advisory board of Internal Medicine News.
FROM THE NEW ENGLAND JOURNAL OF MEDICINE
Meet a fierce advocate for women’s health: Jen Gunter, MD
Jen Gunter, MD, refuses to stay silent when she sees misleading claims about women’s health products.
In fact, the world’s most famous – and outspoken – ob.gyn. (as described by The Guardian), is on a social media mission to speak up whenever she sees companies or governments “prey on women’s health and vaginal shame.”
With nearly 400,000 followers, Dr. Gunter never shies away from a controversy.
Recently, she railed against vitamin and supplement maker Olly’s vaginal probiotic, taking the company to task for its product premise and objectionable ad copy.
This news organization caught up with the San Francisco–based doctor and author of two books, “The Vagina Bible” and “The Menopause Manifesto.” The following interview has been lightly edited for length and clarity.
Question: So these Olly capsules purport to be “Probiotics for Your Panty Hamster.” What was your reaction to this?
Answer: Seeing the word “panty hamsters” is so egregious. I’m so used to baseline vaginal opportunism, but this was just absolutely egregious and I had to call it out.
Question: What are vaginal probiotics anyway?
Answer: These are one of these big wellness scams where companies try to sell you on somehow hacking your microbiome by taking them. They’re not inexpensive, either, and can range in price from $30 to $150 per month, depending on how bespoke they are. And yet the data isn’t good. There is little to no evidence of the value of these probiotics except to shareholders.
Question: What’s one claim made in the Olly probiotic packaging that bothers you the most?
Answer: The product claims to balance the vaginal pH. To say that is a gross misunderstanding of the vaginal ecosystem. If that tagline is what you’re leading with, what else don’t you know?
Also, if these things worked, we’d recommend them. Vaginitis is complex and often misdiagnosed, and it’s easy for a company to be predatory and swoop in and say they have a product for you.
If I think your product for the vagina is awful and you have not studied it in at least one quality clinical trial (never mind company-funded or not), and your marketing displays a stunning ignorance about vaginal health, don’t approach me about your product. Really.
Question: When there’s a pop culture reference to, say, menstruation, you’re quick to weigh in.
Answer: I saw these viral messages from a boy mom (that’s what she called herself) where she wrote about being disgusted that there were mentions of periods in Turning Red, the animated movie.
Everything is here because of menstruation. If you didn’t menstruate, you wouldn’t have a kid, we wouldn’t have the person who had the intelligence to build the computer you’re spreading this message on. Menstruation is a vital part of human reproduction, and it’s far more complex than people think. For that reason alone, people should know about it.
Question: Do you ever get worried about being so “out there” on social media?
Answer: I have my stalkers I suppose, but the trolls don’t bother me. I don’t care if some whatever art dealer in New York thinks I have mental illness for promoting masks. That’s the best you’ve got? Honestly, this doesn’t even register with me. It’s like throwing a grain of sand at a car.
Question: You also got into an exchange with Dr. Leana Wen, CNN’s medical analyst, about mask wearing.
Answer: She obviously has a different opinion than I do. I think one of the biggest issues in the pandemic is the change in messaging and this idea that somehow people aren’t living their normal lives right now. I was sad to see her promote that concept.
This weekend I went out for lunch, I went furniture shopping, I went to the movies, I took a hike. My family and I wear masks everywhere. I fail to understand how wearing a mask means you’re not living a normal life when it’s clearly linked with the reduced spread of the virus.
Almost everything in medicine is about risk reduction. You can do things to lower your risk of heart disease. It’s not 100% guaranteed, but wouldn’t we want a lower risk of bad things? I’m going to keep wearing a mask forever!
Question: Do you wish more doctors were more vocal like you?
Answer: I wish more doctors would have conversations about health outside of the office in ways they’re comfortable with. Like, you’re at the hairdresser and you share information, or you share information with 15 of your Facebook friends. If you’re a doctor and post an article about COVID-19 and how it impacts the heart, your 15 friends are more likely to read that article than if your friend who’s a lawyer puts that up.
As doctors, I believe we can often influence people in big and small ways.

Doctors treat osteoporosis with hormone therapy against guidelines
This type of hormone therapy (HT) can be given as estrogen or a combination of hormones including estrogen. The physicians interviewed for this piece who prescribe HT for osteoporosis suggest the benefits outweigh the downsides to its use for some of their patients. But such doctors may be a minority group, suggests Michael R. McClung, MD, founding director of the Oregon Osteoporosis Center, Portland.
According to Dr. McClung, HT is now rarely prescribed as treatment – as opposed to prevention – for osteoporosis in the absence of additional benefits such as reducing vasomotor symptoms.
Researchers’ findings on HT use in women with osteoporosis are complex. While HT is approved for menopausal prevention of osteoporosis, it is not indicated as a treatment for the disease by the Food and Drug Administration. See the prescribing information for Premarin tablets, which contain a mixture of estrogen hormones, for an example of the FDA’s indications and usage for the type of HT addressed in this article.
Women’s Health Initiative findings
The Women’s Health Initiative (WHI) hormone therapy trials showed that HT reduces the incidence of all osteoporosis-related fractures in postmenopausal women, even those at low risk of fracture, but osteoporosis-related fractures was not a study endpoint. These trials also revealed that HT was associated with increased risks of cardiovascular and cerebrovascular events, an increased risk of breast cancer, and other adverse health outcomes.
The release of the interim results of the WHI trials in 2002 led to a fair amount of fear and confusion about the use of HT after menopause. After the WHI findings were published, estrogen use dropped dramatically, but for everything, including for vasomotor symptoms and the prevention and treatment of osteoporosis.
Prior to the WHI study, it was very common for hormone therapy to be prescribed as women neared or entered menopause, said Risa Kagan MD, clinical professor of obstetrics, gynecology, and reproductive sciences, University of California, San Francisco.
“When a woman turned 50, that was one of the first things we did – was to put her on hormone therapy. All that changed with the WHI, but now we are coming full circle,” noted Dr. Kagan, who currently prescribes HT as first line treatment for osteoporosis to some women.
Hormone therapy’s complex history
HT’s ability to reduce bone loss in postmenopausal women is well-documented in many papers, including one published March 8, 2018, in Osteoporosis International, by Dr. Kagan and colleagues. This reduced bone loss has been shown to significantly reduce fractures in patients with low bone mass and osteoporosis.
While a growing number of therapies are now available to treat osteoporosis, HT was traditionally viewed as a standard method of preventing fractures in this population. It was also widely used to prevent other types of symptoms associated with the menopause, such as hot flashes, night sweats, and sleep disturbances, and multiple observational studies had demonstrated that its use appeared to reduce the incidence of cardiovascular disease (CVD) in symptomatic menopausal women who initiated HT in early menopause.
Even though the WHI studies were the largest randomized trials ever performed in postmenopausal women, they had notable limitations, according to Dr. Kagan.
“The women were older – the average age was 63 years,” she said. “And they only investigated one route and one dose of estrogen.”
Since then, many different formulations and routes of administration with more favorable safety profiles than what was used in the WHI have become available.
It’s both scientifically and clinically unsound to extrapolate the unfavorable risk-benefit profile of HT seen in the WHI trials to all women regardless of age, HT dosage or formulation, or the length of time they’re on it, she added.
Today’s use of HT in women with osteoporosis
Re-analyses and follow-up studies from the WHI trials, along with data from other studies, have suggested that the benefit-risk profiles of HT are affected by a variety of factors. These include the timing of use in relation to menopause and chronological age and the type of hormone regimen.
“Clinically, many advocate for [hormone therapy] use, especially in the newer younger postmenopausal women to prevent bone loss, but also in younger women who are diagnosed with osteoporosis and then as they get older transition to more bone specific agents,” noted Dr. Kagan.
“Some advocate preserving bone mass and preventing osteoporosis and even treating the younger newly postmenopausal women who have no contraindications with hormone therapy initially, and then gradually transitioning them to a bone specific agent as they get older and at risk for fracture.
“If a woman is already fractured and/or has very low bone density with no other obvious secondary metabolic reason, we also often advocate anabolic agents for 1-2 years then consider estrogen for maintenance – again, if [there is] no contraindication to using HT,” she added.
Thus, an individualized approach is recommended to determine a woman’s risk-benefit ratio of HT use based on the absolute risk of adverse effects, Dr. Kagan noted.
“Transdermal and low/ultra-low doses of HT, have a favorable risk profile, and are effective in preserving bone mineral density and bone quality in many women,” she said.
According to Dr. McClung, HT “is most often used for treatment in women in whom hormone therapy was begun for hot flashes and then, when osteoporosis was found later, was simply continued.
“Society guidelines are cautious about recommending hormone therapy for osteoporosis treatment since estrogen is not approved for treatment, despite the clear fracture protection benefit observed in the WHI study,” he said. “Since [women in the WHI trials] were not recruited as having osteoporosis, those results do not meet the FDA requirement for treatment approval, namely the reduction in fracture risk in patients with osteoporosis. However, knowing what we know about the salutary skeletal effects of estrogen, many of us do use them in our patients with osteoporosis – although not prescribed for that purpose.”
Additional scenarios when doctors may advise HT
“I often recommend – and I think colleagues do as well – that women with recent menopause and menopausal symptoms who also have low bone mineral density or even scores showing osteoporosis see their gynecologist to discuss HT for a few years, perhaps until age 60 if no contraindications, and if it is well tolerated,” said Ethel S. Siris, MD, professor of medicine at Columbia University Medical Center in New York.
“Once they stop it we can then give one of our other bone drugs, but it delays the need to start them since on adequate estrogen the bone density should remain stable while they take it,” added Dr. Siris, an endocrinologist and internist, and director of the Toni Stabile Osteoporosis Center in New York. “They may need a bisphosphonate or another bone drug to further protect them from bone loss and future fracture [after stopping HT].”
Victor L. Roberts, MD, founder of Endocrine Associates of Florida, Lake Mary, pointed out that women now have many options for treatment of osteoporosis.
“If a woman is in early menopause and is having other symptoms, then estrogen is warranted,” he said. “If she has osteoporosis, then it’s a bonus.”
“We have better agents that are bone specific,” for a patient who presents with osteoporosis and no other symptoms, he said.
“If a woman is intolerant of alendronate or other similar drugs, or chooses not to have an injectable, then estrogen or a SERM [selective estrogen receptor modulator] would be an option.”
Dr. Roberts added that HT would be more of a niche drug.
“It has a role and documented benefit and works,” he said. “There is good scientific data for the use of estrogen.”
Dr. Kagan is a consultant for Pfizer, Therapeutics MD, Amgen, on the Medical and Scientific Advisory Board of American Bone Health. The other experts interviewed for this piece reported no conflicts.

“I often recommend – and I think colleagues do as well – that women with recent menopause and menopausal symptoms who also have low bone mineral density or even scores showing osteoporosis see their gynecologist to discuss HT for a few years, perhaps until age 60 if no contraindications, and if it is well tolerated,” said Ethel S. Siris, MD, professor of medicine at Columbia University Medical Center in New York.
“Once they stop it we can then give one of our other bone drugs, but it delays the need to start them since on adequate estrogen the bone density should remain stable while they take it,” added Dr. Siris, an endocrinologist and internist, and director of the Toni Stabile Osteoporosis Center in New York. “They may need a bisphosphonate or another bone drug to further protect them from bone loss and future fracture [after stopping HT].”
Victor L. Roberts, MD, founder of Endocrine Associates of Florida, Lake Mary, pointed out that women now have many options for treatment of osteoporosis.
“If a woman is in early menopause and is having other symptoms, then estrogen is warranted,” he said. “If she has osteoporosis, then it’s a bonus.”
“We have better agents that are bone specific,” for a patient who presents with osteoporosis and no other symptoms, he said.
“If a woman is intolerant of alendronate or other similar drugs, or chooses not to have an injectable, then estrogen or a SERM [selective estrogen receptor modulator] would be an option.”
Dr. Roberts added that HT would be more of a niche drug.
“It has a role and documented benefit and works,” he said. “There is good scientific data for the use of estrogen.”

This type of hormone therapy (HT) can be given as estrogen or a combination of hormones including estrogen. The physicians interviewed for this piece who prescribe HT for osteoporosis suggest the benefits outweigh the downsides to its use for some of their patients. But such doctors may be a minority group, suggests Michael R. McClung, MD, founding director of the Oregon Osteoporosis Center, Portland.
According to Dr. McClung, HT is now rarely prescribed as treatment – as opposed to prevention – for osteoporosis in the absence of additional benefits such as reducing vasomotor symptoms.
Researchers’ findings on HT use in women with osteoporosis are complex. While HT is approved for menopausal prevention of osteoporosis, it is not indicated as a treatment for the disease by the Food and Drug Administration. See the prescribing information for Premarin tablets, which contain a mixture of estrogen hormones, for an example of the FDA’s indications and usage for the type of HT addressed in this article.
Women’s Health Initiative findings
The Women’s Health Initiative (WHI) hormone therapy trials showed that HT reduces the incidence of all osteoporosis-related fractures in postmenopausal women, even those at low risk of fracture, but osteoporosis-related fractures was not a study endpoint. These trials also revealed that HT was associated with increased risks of cardiovascular and cerebrovascular events, an increased risk of breast cancer, and other adverse health outcomes.
The release of the interim results of the WHI trials in 2002 led to a fair amount of fear and confusion about the use of HT after menopause. After the WHI findings were published, estrogen use dropped dramatically, but for everything, including for vasomotor symptoms and the prevention and treatment of osteoporosis.
Prior to the WHI study, it was very common for hormone therapy to be prescribed as women neared or entered menopause, said Risa Kagan MD, clinical professor of obstetrics, gynecology, and reproductive sciences, University of California, San Francisco.
“When a woman turned 50, that was one of the first things we did – was to put her on hormone therapy. All that changed with the WHI, but now we are coming full circle,” noted Dr. Kagan, who currently prescribes HT as first line treatment for osteoporosis to some women.
Hormone therapy’s complex history
HT’s ability to reduce bone loss in postmenopausal women is well-documented in many papers, including one published March 8, 2018, in Osteoporosis International, by Dr. Kagan and colleagues. This reduced bone loss has been shown to significantly reduce fractures in patients with low bone mass and osteoporosis.
While a growing number of therapies are now available to treat osteoporosis, HT was traditionally viewed as a standard method of preventing fractures in this population. It was also widely used to prevent other types of symptoms associated with the menopause, such as hot flashes, night sweats, and sleep disturbances, and multiple observational studies had demonstrated that its use appeared to reduce the incidence of cardiovascular disease (CVD) in symptomatic menopausal women who initiated HT in early menopause.
Even though the WHI studies were the largest randomized trials ever performed in postmenopausal women, they had notable limitations, according to Dr. Kagan.
“The women were older – the average age was 63 years,” she said. “And they only investigated one route and one dose of estrogen.”
Since then, many different formulations and routes of administration with more favorable safety profiles than what was used in the WHI have become available.
It’s both scientifically and clinically unsound to extrapolate the unfavorable risk-benefit profile of HT seen in the WHI trials to all women regardless of age, HT dosage or formulation, or the length of time they’re on it, she added.
Today’s use of HT in women with osteoporosis
Re-analyses and follow-up studies from the WHI trials, along with data from other studies, have suggested that the benefit-risk profiles of HT are affected by a variety of factors. These include the timing of use in relation to menopause and chronological age and the type of hormone regimen.
“Clinically, many advocate for [hormone therapy] use, especially in the newer younger postmenopausal women to prevent bone loss, but also in younger women who are diagnosed with osteoporosis and then as they get older transition to more bone specific agents,” noted Dr. Kagan.
“Some advocate preserving bone mass and preventing osteoporosis and even treating the younger newly postmenopausal women who have no contraindications with hormone therapy initially, and then gradually transitioning them to a bone specific agent as they get older and at risk for fracture.
“If a woman is already fractured and/or has very low bone density with no other obvious secondary metabolic reason, we also often advocate anabolic agents for 1-2 years then consider estrogen for maintenance – again, if [there is] no contraindication to using HT,” she added.
Thus, an individualized approach is recommended to determine a woman’s risk-benefit ratio of HT use based on the absolute risk of adverse effects, Dr. Kagan noted.
“Transdermal and low/ultra-low doses of HT, have a favorable risk profile, and are effective in preserving bone mineral density and bone quality in many women,” she said.
According to Dr. McClung, HT “is most often used for treatment in women in whom hormone therapy was begun for hot flashes and then, when osteoporosis was found later, was simply continued.
“Society guidelines are cautious about recommending hormone therapy for osteoporosis treatment since estrogen is not approved for treatment, despite the clear fracture protection benefit observed in the WHI study,” he said. “Since [women in the WHI trials] were not recruited as having osteoporosis, those results do not meet the FDA requirement for treatment approval, namely the reduction in fracture risk in patients with osteoporosis. However, knowing what we know about the salutary skeletal effects of estrogen, many of us do use them in our patients with osteoporosis – although not prescribed for that purpose.”

2022 Update on gynecologic cancer
Despite the challenges of an ongoing COVID-19 pandemic, researchers in 2021 delivered practice-changing studies in gynecologic oncology. In this cancer Update, we highlight 4 studies that shed light on the surgical and systemic therapies that may improve outcomes for patients with cancers of the ovary, endometrium, and cervix. We review DESKTOP III, a trial that investigated the role of cytoreductive surgery in patients with recurrent ovarian cancer, and SENTOR, a study that evaluated the performance of sentinel lymph node biopsy in patients with high-grade endometrial cancers. Additionally, we examine 2 studies of systemic therapy that reveal the growing role of targeted therapies and immuno-oncology in the treatment of gynecologic malignancies.
A new era for patients with BRCA mutation–associated ovarian cancer
Banerjee S, Moore KN, Colombo N, et al. Maintenance olaparib for patients with newly diagnosed advanced ovarian cancer and a BRCA mutation (SOLO1/GOG 3004): 5-year follow-up of a randomised, double-blind, placebo-controlled, phase 3 trial. Lancet Oncol. 2021;22:1721-1731.
Ovarian cancer remains the most lethal gynecologic malignancy due to the frequency of advanced-stage diagnosis and frequent relapse after primary therapy. But for ovarian cancer patients with inherited mutations of the BRCA1 or BRCA2 genes, poly(ADP-ribose) polymerase (PARP) inhibitors, a class of oral anticancer medicines that target DNA repair, have ushered in a new era in which the possibility of long-term remission, and even cure, is more likely than at any other time.
Olaparib trial details
The SOLO1 study was a double-blind, placebo-controlled, phase 3 trial that investigated the role of PARP inhibitor maintenance therapy with olaparib in patients with pathologic BRCA1 or BRCA2 mutations who responded to platinum-based chemotherapy administered for a newly diagnosed, advanced-stage ovarian cancer.1 The study enrolled 391 patients, with 260 randomly assigned to receive olaparib for 24 months and 131 patients randomly assigned to receive placebo tablets. Most patients in the study had a mutation in the BRCA1 gene (72%), 27% had a BRCA2 mutation, and 1% had mutations in both genes.
The primary analysis of SOLO1 was published in 2018 and was based on a median follow-up of 3.4 years.1 That study showed that olaparib maintenance therapy resulted in a large progression-free survival benefit and led to its approval by the US Food and Drug Administration (FDA) as a maintenance therapy for patients with BRCA-mutated advanced ovarian cancer who responded to first-line platinum-based chemotherapy.
In 2021, Banerjee and colleagues updated the progression-free survival results for the SOLO1 trial after 5 years of follow-up.2 In this study, the patients randomly assigned to olaparib maintenance therapy had a persistent and statistically significant progression-free survival benefit, with the median progression-free survival reaching 56 months among the olaparib group compared with 13.8 months in the placebo group (hazard ratio [HR], 0.33; 95% confidence interval [CI], 0.25–0.43).2 Olaparib maintenance therapy resulted in more clinically significant adverse events, including anemia and neutropenia. Serious adverse events occurred in 55 (21%) of the olaparib-treated patients and 17 (13%) of the placebo-treated patients, but no treatment-related adverse events were fatal.
The updated progression-free survival data from the SOLO1 study provides important and promising evidence that frontline PARP inhibitor maintenance therapy may affect long-term remission in an unprecedented proportion of patients with BRCA-related ovarian cancer. Significant, sustained benefit was seen well beyond the end of treatment, and median progression-free survival was an astonishing 3.5 years longer in the olaparib treatment group than among patients who received placebo therapy.

Cytoreductive surgery for recurrent ovarian cancer improves survival in well-selected patients
Harter P, Sehouli J, Vergote I, et al; DESKTOP III Investigators. Randomized trial of cytoreductive surgery for relapsed ovarian cancer. N Engl J Med. 2021;385:2123- 2131.
In the DESKTOP III trial, Harter and colleagues contribute results to the ongoing discourse surrounding treatment options for patients with recurrent, platinum-sensitive ovarian cancer.3 Systemic therapies continue to be the mainstay of treatment in this setting; however, several groups have attempted to evaluate the role of secondary cytoreductive surgery in this setting.4,5
Specific inclusion criteria employed
The DESKTOP III investigators randomly assigned 407 patients with platinum-sensitive recurrent ovarian cancer to secondary cytoreductive surgery followed by platinum-based chemotherapy (n = 206) or platinum-based chemotherapy alone (n = 201).3 An essential aspect of the study’s design was the use of specific inclusion criteria known to identify patients with a high likelihood of complete resection at the time of secondary cytoreduction.6,7 Patients were eligible only if they had at least a 6-month remission following platinum-based chemotherapy, had a complete resection at their previous surgery, had no restriction on physical activity, and had ascites of no more than 500 mL.
Surgery group had superior overall and progression-free survival
After a median follow-up of approximately 70 months, patients randomly assigned to surgery had superior overall survival (53.7 months) compared with those assigned to chemotherapy alone (46.0 months; HR, 0.75; 95% CI, 0.59–0.96).3 Progression-free survival also was improved among patients who underwent surgery (median 18.4 vs 12.7 months; HR, 0.66; 95% CI, 0.54–0.82). Subgroup analyses did not identify any subset of patients who did not benefit from surgery. Whether a complete resection was achieved at secondary cytoreduction was highly prognostic: Patients who had a complete resection had a median overall survival of 61.9 months compared with 27.7 months in patients with residual disease. There were no deaths within 90 days of surgery.
The DESKTOP III trial provides compelling evidence that secondary cytoreductive surgery improves overall and progression-free survival among well-selected patients with recurrent, platinum-sensitive ovarian cancer. These results differ from those of a recently reported Gynecologic Oncology Group (GOG) trial that failed to detect a survival benefit for secondary cytoreductive surgery among patients with platinum-sensitive recurrent ovarian cancer.5 Key differences, which might explain the studies’ seemingly contradictory results, were that the GOG study had fewer specific eligibility criteria than the DESKTOP III trial, and that bevacizumab was administered much more frequently in the GOG study. It is therefore reasonable to discuss the possible benefits of secondary cytoreductive surgery with patients who meet DESKTOP III eligibility criteria, with a focus toward shared decision making and a candid discussion of the potential risks and benefits of secondary cytoreduction.

Immunotherapy enters first-line treatment regimen for advanced cervical cancer
Colombo N, Dubot C, Lorusso D, et al; KEYNOTE-826 Investigators. Pembrolizumab for persistent, recurrent, or metastatic cervical cancer. N Engl J Med. 2021;385:1856-1867.
Persistent, recurrent, and metastatic cervical cancer carries a very poor prognosis: Most patients progress less than a year after starting treatment, and fewer than half survive for 2 years. First-line treatment in this setting has been platinum-based chemotherapy, often given with bevacizumab, a humanized monoclonal antibody that inhibits tumor growth by blocking angiogenesis.8 Pembrolizumab, an immune checkpoint inhibitor, targets cancer cells by blocking their ability to evade the immune system, and it is FDA approved and widely administered to patients with advanced cervical cancer who progress after first-line treatment.9
Addition of pembrolizumab extended survival
In the KEYNOTE-826 trial, Colombo and colleagues investigated the efficacy of incorporating an immune checkpoint inhibitor into the first-line treatment regimen for patients with persistent, recurrent, and metastatic cervical cancer.10 Researchers in this double-blinded, phase 3, randomized controlled trial assigned 617 patients to receive pembrolizumab or placebo concurrently with the investigator’s choice platinum-based chemotherapy. Bevacizumab was administered at the discretion of the treating oncologist.
The proportion of patients who survived at least 2 years following randomization was significantly higher among those assigned to pembrolizumab compared with placebo (53% vs 42%; HR, 0.67, 95% CI, 0.54–0.84).10 Similarly, median progression-free survival was superior among patients who received pembrolizumab compared with those who received placebo (10.4 months vs 8.2 months; HR, 0.65; 95% CI, 0.53–0.79). The role of bevacizumab in conjunction with pembrolizumab and platinum-based chemotherapy was not elucidated in this study because bevacizumab administration was not randomly assigned.
Anemia and neutropenia were the most common adverse events and were more frequent in the pembrolizumab group, but there were no new safety concerns related to concurrent use of pembrolizumab with cytotoxic chemotherapy and bevacizumab. Importantly, subgroup analysis results suggested that pembrolizumab was effective only in patients whose tumors expressed PD-L1 (programmed death ligand 1), a biomarker of pembrolizumab sensitivity in cervical cancer.
In light of the significant improvements in overall and progression-free survival demonstrated in the KEYNOTE-826 trial, in October 2021, the FDA approved the use of frontline pembrolizumab alongside platinum-based chemotherapy, with or without bevacizumab, for treatment of patients with persistent, recurrent, or metastatic cervical cancers that express PD-L1.

Endometrial cancer surgical staging: Is sentinel lymph node biopsy a viable option for high-risk histologies?
Cusimano MC, Vicus D, Pulman K, et al. Assessment of sentinel lymph node biopsy vs lymphadenectomy for intermediate- and high-grade endometrial cancer staging. JAMA Surg. 2021;156:157-164.
The use of intraoperative sentinel lymph node mapping and biopsy to identify lymph node metastases among patients undergoing surgical staging for endometrial cancer has become increasingly common. Lymph node status is an important prognostic factor, and it guides adjuvant treatment decisions in endometrial cancer. However, traditional pelvic and para-aortic lymphadenectomy is associated with increased risk of lower-extremity lymphedema, postoperative complications, and intraoperative injury.
Sentinel lymph node biopsy seeks to identify lymph node metastases while minimizing surgical morbidity by identifying and excising only lymph nodes that directly receive lymphatic drainage from the uterus. The combination of a fluorescent dye (indocyanine green) and near infrared cameras have led to the broad adoption of sentinel lymph node biopsy in endometrial cancer staging surgery. This practice is supported by prospective studies that demonstrate the high diagnostic accuracy of this approach.11,12 However, because most patients included in prior studies had low-grade endometrial cancer, the utility of sentinel lymph node biopsy in cases of high-grade histology has been less clear.
Sentinel lymph node biopsy vs lymphadenectomy for staging
In the SENTOR trial, Cusimano and colleagues examined the diagnostic accuracy of sentinel lymph node mapping and biopsy, using indocyanine green, in patients with intermediate- or high-grade early-stage endometrial cancer.13
All eligible patients (N = 156) underwent traditional or robot-assisted laparoscopic hysterectomy with sentinel lymph node biopsy. Subsequently, patients with grade 2 endometrioid carcinoma underwent bilateral pelvic lymphadenectomy, and those with high-grade histology (grade 3 endometrioid, serous, carcinosarcoma, clear cell, undifferentiated or dedifferentiated, and mixed high grade) underwent bilateral pelvic and para-aortic lymphadenectomy. The investigators evaluated the diagnostic characteristics of sentinel lymph node biopsy, treating complete lymphadenectomy as the gold standard.
Of the 156 patients enrolled, the median age was 65.5 and median body mass index was 27.5; 126 patients (81%) had high-grade histology. The sentinel lymph node biopsy had a sensitivity of 96% (95% CI, 81%–100%), identifying 26 of the 27 patients with nodal metastases. The false-negative rate was 4% (95% CI, 0%–9%) and the negative predictive value was 99% (95% CI, 96%–100%). Intraoperative adverse events occurred in 5 patients (3%), but none occurred during the sentinel lymph node biopsy. ●
The high sensitivity and negative predictive value of sentinel lymph node biopsy in the intermediate- and high-grade cohort included in the SENTOR trial are concordant with prior studies that predominantly included patients with low-grade endometrial cancer. These findings suggest that sentinel lymph node mapping and biopsy is a reasonable option for surgical staging, not only for patients with low-grade endometrial cancer but also for those with intermediate- and high-grade disease.

The proportion of patients who survived at least 2 years following randomization was significantly higher among those assigned to pembrolizumab compared with placebo (53% vs 42%; HR, 0.67, 95% CI, 0.54–0.84).10 Similarly, median progression-free survival was superior among patients who received pembrolizumab compared with those who received placebo (10.4 months vs 8.2 months; HR, 0.65; 95% CI, 0.53–0.79). The role of bevacizumab in conjunction with pembrolizumab and platinum-based chemotherapy was not elucidated in this study because bevacizumab administration was not randomly assigned.
Anemia and neutropenia were the most common adverse events and were more frequent in the pembrolizumab group, but there were no new safety concerns related to concurrent use of pembrolizumab with cytotoxic chemotherapy and bevacizumab. Importantly, subgroup analysis results suggested that pembrolizumab was effective only in patients whose tumors expressed PD-L1 (programmed death ligand 1), a biomarker of pembrolizumab sensitivity in cervical cancer.
In light of the significant improvements in overall and progression-free survival demonstrated in the KEYNOTE-826 trial, in October 2021, the FDA approved the use of frontline pembrolizumab alongside platinum-based chemotherapy, with or without bevacizumab, for treatment of patients with persistent, recurrent, or metastatic cervical cancers that express PD-L1.

Endometrial cancer surgical staging: Is sentinel lymph node biopsy a viable option for high-risk histologies?
Cusimano MC, Vicus D, Pulman K, et al. Assessment of sentinel lymph node biopsy vs lymphadenectomy for intermediate- and high-grade endometrial cancer staging. JAMA Surg. 2021;156:157-164.
The use of intraoperative sentinel lymph node mapping and biopsy to identify lymph node metastases among patients undergoing surgical staging for endometrial cancer has become increasingly common. Lymph node status is an important prognostic factor, and it guides adjuvant treatment decisions in endometrial cancer. However, traditional pelvic and para-aortic lymphadenectomy is associated with increased risk of lower-extremity lymphedema, postoperative complications, and intraoperative injury.
Sentinel lymph node biopsy seeks to identify lymph node metastases while minimizing surgical morbidity by identifying and excising only lymph nodes that directly receive lymphatic drainage from the uterus. The combination of a fluorescent dye (indocyanine green) and near infrared cameras have led to the broad adoption of sentinel lymph node biopsy in endometrial cancer staging surgery. This practice is supported by prospective studies that demonstrate the high diagnostic accuracy of this approach.11,12 However, because most patients included in prior studies had low-grade endometrial cancer, the utility of sentinel lymph node biopsy in cases of high-grade histology has been less clear.
Sentinel lymph node biopsy vs lymphadenectomy for staging
In the SENTOR trial, Cusimano and colleagues examined the diagnostic accuracy of sentinel lymph node mapping and biopsy, using indocyanine green, in patients with intermediate- or high-grade early-stage endometrial cancer.13
All eligible patients (N = 156) underwent traditional or robot-assisted laparoscopic hysterectomy with sentinel lymph node biopsy. Subsequently, patients with grade 2 endometrioid carcinoma underwent bilateral pelvic lymphadenectomy, and those with high-grade histology (grade 3 endometrioid, serous, carcinosarcoma, clear cell, undifferentiated or dedifferentiated, and mixed high grade) underwent bilateral pelvic and para-aortic lymphadenectomy. The investigators evaluated the diagnostic characteristics of sentinel lymph node biopsy, treating complete lymphadenectomy as the gold standard.
Of the 156 patients enrolled, the median age was 65.5 and median body mass index was 27.5; 126 patients (81%) had high-grade histology. The sentinel lymph node biopsy had a sensitivity of 96% (95% CI, 81%–100%), identifying 26 of the 27 patients with nodal metastases. The false-negative rate was 4% (95% CI, 0%–9%) and the negative predictive value was 99% (95% CI, 96%–100%). Intraoperative adverse events occurred in 5 patients (3%), but none occurred during the sentinel lymph node biopsy. ●
The high sensitivity and negative predictive value of sentinel lymph node biopsy in the intermediate- and high-grade cohort included in the SENTOR trial are concordant with prior studies that predominantly included patients with low-grade endometrial cancer. These findings suggest that sentinel lymph node mapping and biopsy is a reasonable option for surgical staging, not only for patients with low-grade endometrial cancer but also for those with intermediate- and high-grade disease.
Despite the challenges of an ongoing COVID-19 pandemic, researchers in 2021 delivered practice-changing studies in gynecologic oncology. In this cancer Update, we highlight 4 studies that shed light on the surgical and systemic therapies that may improve outcomes for patients with cancers of the ovary, endometrium, and cervix. We review DESKTOP III, a trial that investigated the role of cytoreductive surgery in patients with recurrent ovarian cancer, and SENTOR, a study that evaluated the performance of sentinel lymph node biopsy in patients with high-grade endometrial cancers. Additionally, we examine 2 studies of systemic therapy that reveal the growing role of targeted therapies and immuno-oncology in the treatment of gynecologic malignancies.
A new era for patients with BRCA mutation–associated ovarian cancer
Banerjee S, Moore KN, Colombo N, et al. Maintenance olaparib for patients with newly diagnosed advanced ovarian cancer and a BRCA mutation (SOLO1/GOG 3004): 5-year follow-up of a randomised, double-blind, placebo-controlled, phase 3 trial. Lancet Oncol. 2021;22:1721-1731.
Ovarian cancer remains the most lethal gynecologic malignancy due to the frequency of advanced-stage diagnosis and frequent relapse after primary therapy. But for ovarian cancer patients with inherited mutations of the BRCA1 or BRCA2 genes, poly(ADP-ribose) polymerase (PARP) inhibitors, a class of oral anticancer medicines that target DNA repair, have ushered in a new era in which the possibility of long-term remission, and even cure, is more likely than at any other time.
Olaparib trial details
The SOLO1 study was a double-blind, placebo-controlled, phase 3 trial that investigated the role of PARP inhibitor maintenance therapy with olaparib in patients with pathologic BRCA1 or BRCA2 mutations who responded to platinum-based chemotherapy administered for a newly diagnosed, advanced-stage ovarian cancer.1 The study enrolled 391 patients, with 260 randomly assigned to receive olaparib for 24 months and 131 patients randomly assigned to receive placebo tablets. Most patients in the study had a mutation in the BRCA1 gene (72%), 27% had a BRCA2 mutation, and 1% had mutations in both genes.
The primary analysis of SOLO1 was published in 2018 and was based on a median follow-up of 3.4 years.1 That study showed that olaparib maintenance therapy resulted in a large progression-free survival benefit and led to its approval by the US Food and Drug Administration (FDA) as a maintenance therapy for patients with BRCA-mutated advanced ovarian cancer who responded to first-line platinum-based chemotherapy.
In 2021, Banerjee and colleagues updated the progression-free survival results for the SOLO1 trial after 5 years of follow-up.2 In this study, the patients randomly assigned to olaparib maintenance therapy had a persistent and statistically significant progression-free survival benefit, with the median progression-free survival reaching 56 months among the olaparib group compared with 13.8 months in the placebo group (hazard ratio [HR], 0.33; 95% confidence interval [CI], 0.25–0.43).2 Olaparib maintenance therapy resulted in more clinically significant adverse events, including anemia and neutropenia. Serious adverse events occurred in 55 (21%) of the olaparib-treated patients and 17 (13%) of the placebo-treated patients, but no treatment-related adverse events were fatal.
The updated progression-free survival data from the SOLO1 study provides important and promising evidence that frontline PARP inhibitor maintenance therapy may affect long-term remission in an unprecedented proportion of patients with BRCA-related ovarian cancer. Significant, sustained benefit was seen well beyond the end of treatment, and median progression-free survival was an astonishing 3.5 years longer in the olaparib treatment group than among patients who received placebo therapy.

Cytoreductive surgery for recurrent ovarian cancer improves survival in well-selected patients
Harter P, Sehouli J, Vergote I, et al; DESKTOP III Investigators. Randomized trial of cytoreductive surgery for relapsed ovarian cancer. N Engl J Med. 2021;385:2123- 2131.
In the DESKTOP III trial, Harter and colleagues contribute results to the ongoing discourse surrounding treatment options for patients with recurrent, platinum-sensitive ovarian cancer.3 Systemic therapies continue to be the mainstay of treatment in this setting; however, several groups have attempted to evaluate the role of secondary cytoreductive surgery in this setting.4,5
Specific inclusion criteria employed
The DESKTOP III investigators randomly assigned 407 patients with platinum-sensitive recurrent ovarian cancer to secondary cytoreductive surgery followed by platinum-based chemotherapy (n = 206) or platinum-based chemotherapy alone (n = 201).3 An essential aspect of the study’s design was the use of specific inclusion criteria known to identify patients with a high likelihood of complete resection at the time of secondary cytoreduction.6,7 Patients were eligible only if they had at least a 6-month remission following platinum-based chemotherapy, had a complete resection at their previous surgery, had no restriction on physical activity, and had ascites of no more than 500 mL.
Surgery group had superior overall and progression-free survival
After a median follow-up of approximately 70 months, patients randomly assigned to surgery had superior overall survival (53.7 months) compared with those assigned to chemotherapy alone (46.0 months; HR, 0.75; 95% CI, 0.59–0.96).3 Progression-free survival also was improved among patients who underwent surgery (median 18.4 vs 12.7 months; HR, 0.66; 95% CI, 0.54–0.82). Subgroup analyses did not identify any subset of patients who did not benefit from surgery. Whether a complete resection was achieved at secondary cytoreduction was highly prognostic: Patients who had a complete resection had a median overall survival of 61.9 months compared with 27.7 months in patients with residual disease. There were no deaths within 90 days of surgery.
The DESKTOP III trial provides compelling evidence that secondary cytoreductive surgery improves overall and progression-free survival among well-selected patients with recurrent, platinum-sensitive ovarian cancer. These results differ from those of a recently reported Gynecologic Oncology Group (GOG) trial that failed to detect a survival benefit for secondary cytoreductive surgery among patients with platinum-sensitive recurrent ovarian cancer.5 Key differences, which might explain the studies’ seemingly contradictory results, were that the GOG study had fewer specific eligibility criteria than the DESKTOP III trial, and that bevacizumab was administered much more frequently in the GOG study. It is therefore reasonable to discuss the possible benefits of secondary cytoreductive surgery with patients who meet DESKTOP III eligibility criteria, with a focus toward shared decision making and a candid discussion of the potential risks and benefits of secondary cytoreduction.

Immunotherapy enters first-line treatment regimen for advanced cervical cancer
Colombo N, Dubot C, Lorusso D, et al; KEYNOTE-826 Investigators. Pembrolizumab for persistent, recurrent, or metastatic cervical cancer. N Engl J Med. 2021;385:1856-1867.
Persistent, recurrent, and metastatic cervical cancer carries a very poor prognosis: Most patients progress less than a year after starting treatment, and fewer than half survive for 2 years. First-line treatment in this setting has been platinum-based chemotherapy, often given with bevacizumab, a humanized monoclonal antibody that inhibits tumor growth by blocking angiogenesis.8 Pembrolizumab, an immune checkpoint inhibitor, targets cancer cells by blocking their ability to evade the immune system, and it is FDA approved and widely administered to patients with advanced cervical cancer who progress after first-line treatment.9
Addition of pembrolizumab extended survival
In the KEYNOTE-826 trial, Colombo and colleagues investigated the efficacy of incorporating an immune checkpoint inhibitor into the first-line treatment regimen for patients with persistent, recurrent, and metastatic cervical cancer.10 Researchers in this double-blinded, phase 3, randomized controlled trial assigned 617 patients to receive pembrolizumab or placebo concurrently with the investigator’s choice platinum-based chemotherapy.

Antiseptic as good as antibiotics for preventing recurrent UTI
The antiseptic methenamine hippurate (MH) is known to sterilize urine and has been suggested to be of use in preventing urinary tract infections (UTIs), but firm evidence has so far been lacking. Now researchers led by clinicians and scientists from Newcastle-upon-Tyne, England, have provided the ALTAR trial (Alternative to Prophylactic Antibiotics for the Treatment of Recurrent UTIs in Women).
Daily low-dose antibiotics as recommended by current guidelines for prophylactic treatment of recurrent UTI have been linked to antibiotic resistance. Using MH as an alternative could play an important role in helping to tackle the global problem of increasing antibiotic resistance, the team said.
Study details
They recruited 240 women aged 18 or over with recurrent UTIs requiring prophylactic treatment from eight secondary care urology and urogynecology centers in the United Kingdom from June 2016 to June 2018. Women were randomized to receive MH or daily low-dose antibiotics for 12 months, with follow up for a further 6 months beyond that.
Before trial entry the women had experienced an average of more than six UTI episodes per year. During the 12-month treatment period, in the modified intention-to-treat population, there were 90 symptomatic, antibiotic-treated UTI episodes reported over 101 person-years of follow-up in the antibiotic group, and 141 episodes over 102 person-years in the MH group.
This yielded a UTI rate of 0.89 episodes per person-year in the antibiotic group, compared with 1.38 in the MH group, an absolute difference of 0.49 episodes per person-year. In the 6-month posttreatment follow-up period, the UTI incidence rate was 1.19 episodes per person-year in the antibiotic prophylaxis group versus 1.72 in the MH group, an absolute difference of 0.53.
Before the trial, a patient and public involvement group had predefined the noninferiority margin as one episode of UTI per person-year. The small difference between the two groups was less than this, confirming noninferiority of MH to antibiotic prophylaxis in this setting. This finding was consistent across the modified intention-to-treat, strict intention-to-treat, per protocol, and modified per protocol (post hoc) analyses.
Thus the ALTAR results showed that MH was no worse than antibiotics at preventing UTIs, and MH was also associated with reduced antibiotic consumption.
The vast majority of participants were over 90% adherent with the allocated treatment. Patient satisfaction was generally high and rates of adverse events and adverse reactions generally low, and both were comparable between treatment groups. Adverse reactions were reported by 34/142 (24%) in the antibiotic group and 35/127 (28%) in the MH group, and most reactions were mild. In the antibiotic group there were two serious adverse reactions (severe abdominal pain and raised alanine transaminase), whereas six participants in the MH group reported an episode of febrile UTI and four were admitted to hospital because of UTI.
Substantial global health care problem
At least 50% and up to 80% of all women have at least one acute UTI in their lifetime, most often uncomplicated acute cystitis. About a quarter of them go on to suffer recurrent infection, defined as three or more repeat infections in the past year, or two infections in the preceding 6 months. Frequent recurrences thus represent “a substantial global health care problem,” the authors say.
Guidelines from the United Kingdom, Europe, and the United States acknowledge the need for preventive strategies and strongly recommend the use of daily, low-dose antibiotics as standard prophylactic treatment. However, the United Kingdom’s antimicrobial resistance strategy recommends a “strong focus on infection prevention,” and aims to reduce antimicrobial use in humans by 15% before 2024.
“To achieve that, exploration of nonantibiotic preventive treatments in common conditions such as UTI is essential,” the team said.
MH is one such nonantibiotic treatment. It is bactericidal and works by denaturing bacterial proteins and nucleic acids. Although previous Cochrane systematic reviews had concluded that it could be effective for preventing UTI, further large trials were needed.
“This trial adds to the evidence base for the use of MH for prophylactic treatment in adult women with recurrent UTI. Although the MH group had a 55% higher rate of UTI episodes than the antibiotics group, the absolute difference was just 0.49 UTI episodes per year, which has limited clinical consequence,” the team concluded.
Results could ‘support a change in practice’
In older patients, particularly, the risks of long-term antibiotic prophylaxis might outweigh the benefits, and the authors said that their results “could support a change in practice in terms of preventive treatments for recurrent UTI and provide patients and clinicians with a credible alternative to daily antibiotics, giving them the confidence to pursue strategies that avoid long-term antibiotic use.”
They acknowledged limitations of the study, including that treatment allocation was not masked, crossover between arms was allowed, and differences in antibiotics prescribed may have affected the results. In addition, data regarding long-term safety of MH are scarce.
However, they said that the trial accurately represented the broad range of women with recurrent UTI, and that its results “might encourage patients and clinicians to consider MH as a first line treatment for UTI prevention in women.”
In a linked editorial, scientists from the Institute for Evidence-Based Healthcare at Bond University in Queensland, Australia, commented: “Although the results need cautious interpretation, they align with others, and this new research increases the confidence with which MH can be offered as an option to women needing prophylaxis against recurrent urinary tract infection.”

About a quarter of them go on to suffer recurrent infection, defined as three or more repeat infections in the past year, or two infections in the preceding 6 months. Frequent recurrences thus represent “a substantial global health care problem,” the authors say.
Guidelines from the United Kingdom, Europe, and the United States acknowledge the need for preventive strategies and strongly recommend the use of daily, low-dose antibiotics as standard prophylactic treatment. However, the United Kingdom’s antimicrobial resistance strategy recommends a “strong focus on infection prevention,” and aims to reduce antimicrobial use in humans by 15% before 2024.
“To achieve that, exploration of nonantibiotic preventive treatments in common conditions such as UTI is essential,” the team said.
MH is one such nonantibiotic treatment. It is bactericidal and works by denaturing bacterial proteins and nucleic acids. Although previous Cochrane systematic reviews had concluded that it could be effective for preventing UTI, further large trials were needed.
“This trial adds to the evidence base for the use of MH for prophylactic treatment in adult women with recurrent UTI. Although the MH group had a 55% higher rate of UTI episodes than the antibiotics group, the absolute difference was just 0.49 UTI episodes per year, which has limited clinical consequence,” the team concluded.
Results could ‘support a change in practice’
In older patients, particularly, the risks of long-term antibiotic prophylaxis might outweigh the benefits, and the authors said that their results “could support a change in practice in terms of preventive treatments for recurrent UTI and provide patients and clinicians with a credible alternative to daily antibiotics, giving them the confidence to pursue strategies that avoid long-term antibiotic use.”
They acknowledged limitations of the study, including that treatment allocation was not masked, crossover between arms was allowed, and differences in antibiotics prescribed may have affected the results. In addition, data regarding long-term safety of MH are scarce.
However, they said that the trial accurately represented the broad range of women with recurrent UTI, and that its results “might encourage patients and clinicians to consider MH as a first line treatment for UTI prevention in women.”
In a linked editorial, scientists from the Institute for Evidence-Based Healthcare at Bond University in Queensland, Australia, commented: “Although the results need cautious interpretation, they align with others, and this new research increases the confidence with which MH can be offered as an option to women needing prophylaxis against recurrent urinary tract infection.”

The antiseptic methenamine hippurate (MH) is known to sterilize urine and has been suggested to be of use in preventing urinary tract infections (UTIs), but firm evidence has so far been lacking. Now researchers led by clinicians and scientists from Newcastle-upon-Tyne, England, have provided the ALTAR trial (Alternative to Prophylactic Antibiotics for the Treatment of Recurrent UTIs in Women).
Daily low-dose antibiotics as recommended by current guidelines for prophylactic treatment of recurrent UTI have been linked to antibiotic resistance. Using MH as an alternative could play an important role in helping to tackle the global problem of increasing antibiotic resistance, the team said.
Study details
They recruited 240 women aged 18 or over with recurrent UTIs requiring prophylactic treatment from eight secondary care urology and urogynecology centers in the United Kingdom from June 2016 to June 2018. Women were randomized to receive MH or daily low-dose antibiotics for 12 months, with follow up for a further 6 months beyond that.
Before trial entry the women had experienced an average of more than six UTI episodes per year. During the 12-month treatment period, in the modified intention-to-treat population, there were 90 symptomatic, antibiotic-treated UTI episodes reported over 101 person-years of follow-up in the antibiotic group, and 141 episodes over 102 person-years in the MH group.
This yielded a UTI rate of 0.89 episodes per person-year in the antibiotic group, compared with 1.38 in the MH group, an absolute difference of 0.49 episodes per person-year. In the 6-month posttreatment follow-up period, the UTI incidence rate was 1.19 episodes per person-year in the antibiotic prophylaxis group versus 1.72 in the MH group, an absolute difference of 0.53.
Before the trial, a patient and public involvement group had predefined the noninferiority margin as one episode of UTI per person-year. The small difference between the two groups was less than this, confirming noninferiority of MH to antibiotic prophylaxis in this setting. This finding was consistent across the modified intention-to-treat, strict intention-to-treat, per protocol, and modified per protocol (post hoc) analyses.
Thus the ALTAR results showed that MH was no worse than antibiotics at preventing UTIs, and MH was also associated with reduced antibiotic consumption.
The vast majority of participants were over 90% adherent with the allocated treatment. Patient satisfaction was generally high and rates of adverse events and adverse reactions generally low, and both were comparable between treatment groups. Adverse reactions were reported by 34/142 (24%) in the antibiotic group and 35/127 (28%) in the MH group, and most reactions were mild. In the antibiotic group there were two serious adverse reactions (severe abdominal pain and raised alanine transaminase), whereas six participants in the MH group reported an episode of febrile UTI and four were admitted to hospital because of UTI.
