Long COVID (postacute sequelae of SARS-CoV-2 infection, or PASC) is an emerging syndrome that affects 50% to 70% of people who survive COVID-19 for up to 3 months or longer after acute disease.¹ It is a multisystem condition that causes dysfunction of respiratory, cardiac, and nervous tissue, at least in part likely due to alterations in cellular energy metabolism and reduced oxygen supply to tissue.³ Patients who have had SARS-CoV-2 infection report persistent symptoms and signs that affect their quality of life. These may include neurocognitive, cardiorespiratory, gastrointestinal, and musculoskeletal symptoms; loss of taste and smell; and constitutional symptoms.² There is no one test to determine if symptoms are due to COVID-19.³

Acute COVID-19 mortality risk factors include increasing age, chronic comorbidities, and male sex. However, long COVID risk factors are quite different. A meta-analysis and review of 20 articles that met inclusion criteria (n = 13,340 study participants), limited by pooling of crude estimates, found that risk factors were female sex and severity of acute disease.⁴ A second meta-analysis of 37 studies with 1 preprint found that female sex and comorbidities such as pulmonary disease, diabetes, and obesity were risk factors for long COVID.⁵ Qualitative analysis of single studies (n = 18 study participants) suggested that older adults can develop more long COVID symptoms than younger adults, but this association between advancing age and long COVID was not supported when data were pooled into a meta-analysis.³ However, both single studies (n = 16 study participants) and the meta-analysis (n = 7 study participants) did support female sex as a risk factor for long COVID, along with single studies suggesting increased risk with medical comorbidities for pulmonary disease, diabetes, and organ transplantation.⁵ In this discussion, we focus on long COVID and its relationship with perimenopause and chronic fatigue syndrome.

Perimenopause

Perimenopause: A temporary disruption to physiologic ovarian steroid hormone production following COVID could acutely exacerbate symptoms of perimenopause and menopause.

JoAnn V. Pinkerton, MD, MSCP

The higher prevalence of long COVID in women younger than 50 years⁶ supports the overlap that studies have shown between symptoms of long COVID and perimenopause,⁷ as the median age of natural menopause is 51 years. Thus, health care providers need to differentiate between long COVID and other conditions, such as perimenopause, which share similar symptoms (FIGURE). Perimenopause might be diagnosed as long COVID, or the 2 might affect each other.

Symptoms of long COVID include fatigue, brain fog, and increased heart rate after recovering from COVID-19 and may continue or increase after an initial infection.⁸ Common symptoms of perimenopause and menopause, which also could be seen with long COVID, include typical menopausal symptoms such as hot flashes, night sweats, or disrupted sleep; changes in mood including dysthymia, depression, anxiety, or emotional lability; cognitive concerns such as brain fog or decreased concentration; and decreased stamina, fatigue, joint and muscle pains, or more frequent headaches. Therefore, women in their 40s or 50s with persistent symptoms after having COVID-19 without an alternative diagnosis, and who present with menstrual irregularity,⁹hot flashes, or night sweats, could be having an exacerbation of perimenopausal symptoms, or they could be experiencing a combination of long COVID and perimenopausal symptoms.

Potential pathophysiology

Inflammation is likely to be critical in the pathogenesis of postacute sequelae of SARS-CoV-2 infection, or PASC. Individuals with long COVID have elevated inflammatory markers for several months.¹⁰ The chronic inflammation associated with long COVID could cause disturbances in the ovary and ovarian hormone production.^2,10,11

During perimenopause, the ovary is more sensitive to illnesses such as COVID-19and to stress. The current theory is that COVID-19 affects the ovary with declines in ovarian reserve and ovarian function⁷ and with potential disruptions to the menstrual cycle, gonadal function, and ovarian sufficiency that lead to issues with menopause or fertility, as well as symptom exacerbation around menstruation.¹² Another theory is that SARS-CoV-2 infection affects ovary hormone production, as there is an abundance of angiotensin-converting enzyme-2 receptors on ovarian and endometrial tissue.¹¹ Thus, it makes sense that long COVID could bring on symptoms of perimenopause or menopause more acutely or more severely or lengthen the duration of perimenopausal symptoms.

Sex differentiation has been seen with regard to symptomatic COVID-19, with women generally faring better.^13,14Estradiol has been shown to have beneficial effects during acute COVID-19.¹⁵ With acute COVID-19 infection, women had lower mortality, lower levels of inflammation, higher lymphocyte counts, and faster antibody responses than men.^13,14 In addition, estradiol has been shown to help perimenopausal and menopausal hot flashes, night sweats, and sleep and to improve mood during perimenopause.¹⁶ So it is likely that perimenopausal or menopausal symptomatic women with long COVID treated with estrogen would see improvements in their symptoms both due to the action of estradiol on the ovary as seen during COVID-19 and in perimenopause.

Perimenopause is the transitional period prior to menopause, when the ovaries gradually produce fewer hormones and is associated with erratic hormonal fluctuations. The length of this transitional period varies from 4 to 10 years. Ethnic variations in the duration of hot flashes have been found, noting that Black and Hispanic women have them for an average of 8 to 10 years (longer), White women for an average of 7 years, and Asian, Japanese, and Chinese women for an average of 5 to 6 years (shorter).¹⁷

What should health care providers ask?

Distinguishing perimenopause from long COVID. It is important to try to differentiate between perimenopause and long COVID, and it is possible to have both, with long COVID exacerbating the menopausal symptoms.^7,8 Health care providers should be alert to consider perimenopause if women present with shorter or longer cycles (21-40 days), missed periods (particularly 60 days or 2 months), or worsening perimenopausal mood, migraines, insomnia, or hot flashes. Clinicians should actively enquire about all of these symptoms.

Moreover, if a perimenopausal woman reports acutely worsening symptoms after COVID-19, health care providers should address the perimenopausal symptoms and determine whether hormone therapy is appropriate and could improve their symptoms. Women do not need to wait until they go 1 year without a period to be treated with hormone therapy to improve perimenopausal and menopausal symptoms. If women with long COVID have perimenopause or menopause symptoms, they should have access to evidence-based information and discuss menopausal hormone therapy if appropriate. Hormone therapy could improve both perimenopausal symptoms and the long COVID symptoms if some of the symptoms are due to changes in ovary function. Health care providers could consider progesterone or antidepressants during the second half of the cycle (luteal phase) or estrogen combined with progesterone for the entire cycle.¹⁸

For health care providers working in long COVID clinics, in addition to asking when symptoms started, what makes symptoms worse, the frequency of symptoms, and which activities are affected, ask about perimenopausal and menopausal symptoms. If a woman has irregular periods, sleep disturbances, fatigue, or mood changes, consider that these could be related to long COVID, perimenopause, or both.^8,18 Be able to offer treatment or refer patients to a women’s health specialist who can assess and offer treatment.

A role for vitamin D? A recent retrospective case-matched study found that 6 months after hospital discharge, patients with long COVID had lower levels of 25(OH) vitamin D with the most notable symptom being brain fog.¹⁹ Thus, there may be a role for vitamin D supplementation as a preventive strategy in those being discharged after hospitalization. Vitamin D levels and supplementation have not been otherwise evaluated to date.

Lifestyle strategies for women with perimenopause and long COVID

Lifestyle strategies should be encouraged for women during perimenopause and long COVID. This includes good nutrition (avoiding carbs and sweets, particularly before menses), getting at least 7 hours of sleep and using sleep hygiene (regular bedtimes, sleep regimen, no late screens), getting regular exercise 5 days per week, reducing stress, avoiding excess alcohol, and not smoking. All of these factors can help women and their ovarian function during this period of ovarian fluctuations.

The timing of menopause and COVID may coincide with midlife stressors, including relationship issues (separations or divorce), health issues for the individual or their partner, widowhood, parenting challenges (care of young children, struggles with adolescents, grown children returning home), being childless, concerns about aging parents and caregiving responsibilities, as well as midlife career, community, or education issues—all of which make both long COVID and perimenopause more challenging to navigate.

Need for research

There is a need for future research to understand the epidemiologic basis and underlying biological mechanisms of sex differences seen in women with long COVID. Studying the effects of COVID-19 on ovarian function could lead to a better understanding of perimenopause, what causes ovarian failure to speed up, and possibly ways to slow it down⁸ since there are health risks of early menopause.¹⁶

Chronic fatigue syndrome

Chronic fatigue syndrome: A large number of patients have “post-COVID conditions” affecting everyday function, including depression/anxiety, insomnia, and chronic fatigue (with a 3:1 female predominance)

Alexandra Kadl, MD

After 3 years battling acute COVID-19 infections, we encounter now a large number of patients with PASC— also known as “long COVID,” “COVID long-hauler syndrome,” and “post-COVID conditions”—a persistent multisystem syndrome that impacts everyday function.¹ As of October 2023, there are more than 100 million COVID-19 survivors reported in the United States; 10% to 85% of COVID survivors2-4 may show lingering, life-altering symptoms after recovery. Common reported symptoms include fatigue, depression/ anxiety, insomnia, and brain fog/difficulty concentrating, which are particularly high in women who often had experienced only mild acute COVID-19 disease and were not even hospitalized. More recently, chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) has been recognized as major component of PASC5 with a 3:1 female predominance.6 Up to 75% of patients with this diagnosis are not able to maintain their jobs and normal life, and up to 25% are so disabled that they are bedbound.⁶

Diagnosis

Although illnesses resembling CFS have been reported for more than 200 years,⁷ the diagnosis of CFS/ME remains difficult to make. There is a likely underreporting due to fear of being labeled as malingering when reaching out to health care providers, and there is a reporting bias toward higher socioeconomic groups due to better access to health care. The current criteria for the diagnosis of CFS/ME include the following 3 components⁸:

1. substantial impairment in the ability to function for more than 6 months, accompanied by profound fatigue, not alleviated by rest
2. post-exertional malaise (PEM; prolonged, disabling exacerbation of the patient’s baseline symptoms after exercise)
3. non-refreshing sleep, PLUS either cognitive impairment or orthostatic intolerance.

Pathophysiology

Originally found to evolve in a small patient population with Epstein-Barr virus infection and Lyme disease, CFS/ME has moved to centerstage after the COVID-19 pandemic. While the diagnosis of COVID-19–related CFS/ME has advanced in the field, a clear mechanistic explanation of why it occurs is still missing. Certain risk factors have been identified for the development of CFS/ME, including female sex, reactivation of herpesviruses, and presence of connective tissue disorders; however, about one-third of patients with CFS/ME do not have identifiable risk factors.^9,10 Persistence of viral particles¹¹ and prolonged inflammatory states are speculated to affect the nervous system and mitochondrial function and metabolism. Interestingly, there is no correlation between severity of initial COVID-19 illness and the development of CFS/ME, similar to observations in non–COVID-19–related CFS/ME.

Proposed therapy

There is currently no proven therapy for CFS/ME. At this time, several immunomodulatory, antiviral, and neuromodulator drugs are being tested in clinical trial networks around the world.¹² Usual physical therapy with near maximum intensity has been shown to exacerbate symptoms and often results in PEM, which is described as a “crash” or “full collapse” by patients. The time for recovery after such episodes can be several days.¹³

Instead, the focus should be on addressing “treatable” concomitant symptoms, such as sleep disorders, anxiety and depression, and chronic pain. Lifestyle changes, avoidance of triggers, and exercise without over exertion are currently recommended to avoid incapacitating PEM.

Gaps in knowledge

There is a large knowledge gap regarding the pathophysiology, prevention, and therapy for CFS/ME. Many health care practitioners are not familiar with the disease and have focused on measurable parameters of exercise limitations and fatigue, such as anemias and lung and cardiac impairments, thus treating CFS/ME as a form of deconditioning. Given the large number of patients who recovered from acute COVID-19 that are now disabled due to CFS/ME, a patient-centered research opportunity has arisen. Biomedical/mechanistic research is ongoing, and well-designed clinical trials evaluating pharmacologic intervention as well as tailored exercise programs are needed.

Conclusion

General practitioners and women’s health specialists need to be aware of CFS/ME, especially when managing patients with long COVID. They also need to know that typical physical therapy may worsen symptoms. Furthermore, clinicians should shy away from trial drugs with a theoretical benefit outside of a clinical trial. ●

Chronic fatigue syndrome

Chronic fatigue syndrome: A large number of patients have “post-COVID conditions” affecting everyday function, including depression/anxiety, insomnia, and chronic fatigue (with a 3:1 female predominance)

Alexandra Kadl, MD

After 3 years battling acute COVID-19 infections, we encounter now a large number of patients with PASC— also known as “long COVID,” “COVID long-hauler syndrome,” and “post-COVID conditions”—a persistent multisystem syndrome that impacts everyday function.¹ As of October 2023, there are more than 100 million COVID-19 survivors reported in the United States; 10% to 85% of COVID survivors2-4 may show lingering, life-altering symptoms after recovery. Common reported symptoms include fatigue, depression/ anxiety, insomnia, and brain fog/difficulty concentrating, which are particularly high in women who often had experienced only mild acute COVID-19 disease and were not even hospitalized. More recently, chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) has been recognized as major component of PASC5 with a 3:1 female predominance.6 Up to 75% of patients with this diagnosis are not able to maintain their jobs and normal life, and up to 25% are so disabled that they are bedbound.⁶

Diagnosis

Although illnesses resembling CFS have been reported for more than 200 years,⁷ the diagnosis of CFS/ME remains difficult to make. There is a likely underreporting due to fear of being labeled as malingering when reaching out to health care providers, and there is a reporting bias toward higher socioeconomic groups due to better access to health care. The current criteria for the diagnosis of CFS/ME include the following 3 components⁸:

1. substantial impairment in the ability to function for more than 6 months, accompanied by profound fatigue, not alleviated by rest
2. post-exertional malaise (PEM; prolonged, disabling exacerbation of the patient’s baseline symptoms after exercise)
3. non-refreshing sleep, PLUS either cognitive impairment or orthostatic intolerance.

Pathophysiology

Originally found to evolve in a small patient population with Epstein-Barr virus infection and Lyme disease, CFS/ME has moved to centerstage after the COVID-19 pandemic. While the diagnosis of COVID-19–related CFS/ME has advanced in the field, a clear mechanistic explanation of why it occurs is still missing. Certain risk factors have been identified for the development of CFS/ME, including female sex, reactivation of herpesviruses, and presence of connective tissue disorders; however, about one-third of patients with CFS/ME do not have identifiable risk factors.^9,10 Persistence of viral particles¹¹ and prolonged inflammatory states are speculated to affect the nervous system and mitochondrial function and metabolism. Interestingly, there is no correlation between severity of initial COVID-19 illness and the development of CFS/ME, similar to observations in non–COVID-19–related CFS/ME.

Proposed therapy

There is currently no proven therapy for CFS/ME. At this time, several immunomodulatory, antiviral, and neuromodulator drugs are being tested in clinical trial networks around the world.¹² Usual physical therapy with near maximum intensity has been shown to exacerbate symptoms and often results in PEM, which is described as a “crash” or “full collapse” by patients. The time for recovery after such episodes can be several days.¹³

Instead, the focus should be on addressing “treatable” concomitant symptoms, such as sleep disorders, anxiety and depression, and chronic pain. Lifestyle changes, avoidance of triggers, and exercise without over exertion are currently recommended to avoid incapacitating PEM.

Gaps in knowledge

There is a large knowledge gap regarding the pathophysiology, prevention, and therapy for CFS/ME. Many health care practitioners are not familiar with the disease and have focused on measurable parameters of exercise limitations and fatigue, such as anemias and lung and cardiac impairments, thus treating CFS/ME as a form of deconditioning. Given the large number of patients who recovered from acute COVID-19 that are now disabled due to CFS/ME, a patient-centered research opportunity has arisen. Biomedical/mechanistic research is ongoing, and well-designed clinical trials evaluating pharmacologic intervention as well as tailored exercise programs are needed.

Conclusion

General practitioners and women’s health specialists need to be aware of CFS/ME, especially when managing patients with long COVID. They also need to know that typical physical therapy may worsen symptoms. Furthermore, clinicians should shy away from trial drugs with a theoretical benefit outside of a clinical trial. ●

Long COVID (postacute sequelae of SARS-CoV-2 infection, or PASC) is an emerging syndrome that affects 50% to 70% of people who survive COVID-19 for up to 3 months or longer after acute disease.¹ It is a multisystem condition that causes dysfunction of respiratory, cardiac, and nervous tissue, at least in part likely due to alterations in cellular energy metabolism and reduced oxygen supply to tissue.³ Patients who have had SARS-CoV-2 infection report persistent symptoms and signs that affect their quality of life. These may include neurocognitive, cardiorespiratory, gastrointestinal, and musculoskeletal symptoms; loss of taste and smell; and constitutional symptoms.² There is no one test to determine if symptoms are due to COVID-19.³

Acute COVID-19 mortality risk factors include increasing age, chronic comorbidities, and male sex. However, long COVID risk factors are quite different. A meta-analysis and review of 20 articles that met inclusion criteria (n = 13,340 study participants), limited by pooling of crude estimates, found that risk factors were female sex and severity of acute disease.⁴ A second meta-analysis of 37 studies with 1 preprint found that female sex and comorbidities such as pulmonary disease, diabetes, and obesity were risk factors for long COVID.⁵ Qualitative analysis of single studies (n = 18 study participants) suggested that older adults can develop more long COVID symptoms than younger adults, but this association between advancing age and long COVID was not supported when data were pooled into a meta-analysis.³ However, both single studies (n = 16 study participants) and the meta-analysis (n = 7 study participants) did support female sex as a risk factor for long COVID, along with single studies suggesting increased risk with medical comorbidities for pulmonary disease, diabetes, and organ transplantation.⁵ In this discussion, we focus on long COVID and its relationship with perimenopause and chronic fatigue syndrome.

Perimenopause

Perimenopause: A temporary disruption to physiologic ovarian steroid hormone production following COVID could acutely exacerbate symptoms of perimenopause and menopause.

JoAnn V. Pinkerton, MD, MSCP

The higher prevalence of long COVID in women younger than 50 years⁶ supports the overlap that studies have shown between symptoms of long COVID and perimenopause,⁷ as the median age of natural menopause is 51 years. Thus, health care providers need to differentiate between long COVID and other conditions, such as perimenopause, which share similar symptoms (FIGURE). Perimenopause might be diagnosed as long COVID, or the 2 might affect each other.

Symptoms of long COVID include fatigue, brain fog, and increased heart rate after recovering from COVID-19 and may continue or increase after an initial infection.⁸ Common symptoms of perimenopause and menopause, which also could be seen with long COVID, include typical menopausal symptoms such as hot flashes, night sweats, or disrupted sleep; changes in mood including dysthymia, depression, anxiety, or emotional lability; cognitive concerns such as brain fog or decreased concentration; and decreased stamina, fatigue, joint and muscle pains, or more frequent headaches. Therefore, women in their 40s or 50s with persistent symptoms after having COVID-19 without an alternative diagnosis, and who present with menstrual irregularity,⁹hot flashes, or night sweats, could be having an exacerbation of perimenopausal symptoms, or they could be experiencing a combination of long COVID and perimenopausal symptoms.

Continue to: Potential pathophysiology...

Potential pathophysiology

Inflammation is likely to be critical in the pathogenesis of postacute sequelae of SARS-CoV-2 infection, or PASC. Individuals with long COVID have elevated inflammatory markers for several months.¹⁰ The chronic inflammation associated with long COVID could cause disturbances in the ovary and ovarian hormone production.^2,10,11

During perimenopause, the ovary is more sensitive to illnesses such as COVID-19and to stress. The current theory is that COVID-19 affects the ovary with declines in ovarian reserve and ovarian function⁷ and with potential disruptions to the menstrual cycle, gonadal function, and ovarian sufficiency that lead to issues with menopause or fertility, as well as symptom exacerbation around menstruation.¹² Another theory is that SARS-CoV-2 infection affects ovary hormone production, as there is an abundance of angiotensin-converting enzyme-2 receptors on ovarian and endometrial tissue.¹¹ Thus, it makes sense that long COVID could bring on symptoms of perimenopause or menopause more acutely or more severely or lengthen the duration of perimenopausal symptoms.

Sex differentiation has been seen with regard to symptomatic COVID-19, with women generally faring better.^13,14Estradiol has been shown to have beneficial effects during acute COVID-19.¹⁵ With acute COVID-19 infection, women had lower mortality, lower levels of inflammation, higher lymphocyte counts, and faster antibody responses than men.^13,14 In addition, estradiol has been shown to help perimenopausal and menopausal hot flashes, night sweats, and sleep and to improve mood during perimenopause.¹⁶ So it is likely that perimenopausal or menopausal symptomatic women with long COVID treated with estrogen would see improvements in their symptoms both due to the action of estradiol on the ovary as seen during COVID-19 and in perimenopause.

Perimenopause is the transitional period prior to menopause, when the ovaries gradually produce fewer hormones and is associated with erratic hormonal fluctuations. The length of this transitional period varies from 4 to 10 years. Ethnic variations in the duration of hot flashes have been found, noting that Black and Hispanic women have them for an average of 8 to 10 years (longer), White women for an average of 7 years, and Asian, Japanese, and Chinese women for an average of 5 to 6 years (shorter).¹⁷

What should health care providers ask?

Distinguishing perimenopause from long COVID. It is important to try to differentiate between perimenopause and long COVID, and it is possible to have both, with long COVID exacerbating the menopausal symptoms.^7,8 Health care providers should be alert to consider perimenopause if women present with shorter or longer cycles (21-40 days), missed periods (particularly 60 days or 2 months), or worsening perimenopausal mood, migraines, insomnia, or hot flashes. Clinicians should actively enquire about all of these symptoms.

Moreover, if a perimenopausal woman reports acutely worsening symptoms after COVID-19, health care providers should address the perimenopausal symptoms and determine whether hormone therapy is appropriate and could improve their symptoms. Women do not need to wait until they go 1 year without a period to be treated with hormone therapy to improve perimenopausal and menopausal symptoms. If women with long COVID have perimenopause or menopause symptoms, they should have access to evidence-based information and discuss menopausal hormone therapy if appropriate. Hormone therapy could improve both perimenopausal symptoms and the long COVID symptoms if some of the symptoms are due to changes in ovary function. Health care providers could consider progesterone or antidepressants during the second half of the cycle (luteal phase) or estrogen combined with progesterone for the entire cycle.¹⁸

For health care providers working in long COVID clinics, in addition to asking when symptoms started, what makes symptoms worse, the frequency of symptoms, and which activities are affected, ask about perimenopausal and menopausal symptoms. If a woman has irregular periods, sleep disturbances, fatigue, or mood changes, consider that these could be related to long COVID, perimenopause, or both.^8,18 Be able to offer treatment or refer patients to a women’s health specialist who can assess and offer treatment.

A role for vitamin D? A recent retrospective case-matched study found that 6 months after hospital discharge, patients with long COVID had lower levels of 25(OH) vitamin D with the most notable symptom being brain fog.¹⁹ Thus, there may be a role for vitamin D supplementation as a preventive strategy in those being discharged after hospitalization. Vitamin D levels and supplementation have not been otherwise evaluated to date.

Lifestyle strategies for women with perimenopause and long COVID

Lifestyle strategies should be encouraged for women during perimenopause and long COVID. This includes good nutrition (avoiding carbs and sweets, particularly before menses), getting at least 7 hours of sleep and using sleep hygiene (regular bedtimes, sleep regimen, no late screens), getting regular exercise 5 days per week, reducing stress, avoiding excess alcohol, and not smoking. All of these factors can help women and their ovarian function during this period of ovarian fluctuations.

The timing of menopause and COVID may coincide with midlife stressors, including relationship issues (separations or divorce), health issues for the individual or their partner, widowhood, parenting challenges (care of young children, struggles with adolescents, grown children returning home), being childless, concerns about aging parents and caregiving responsibilities, as well as midlife career, community, or education issues—all of which make both long COVID and perimenopause more challenging to navigate.

Need for research

There is a need for future research to understand the epidemiologic basis and underlying biological mechanisms of sex differences seen in women with long COVID. Studying the effects of COVID-19 on ovarian function could lead to a better understanding of perimenopause, what causes ovarian failure to speed up, and possibly ways to slow it down⁸ since there are health risks of early menopause.¹⁶

They also need to know that typical physical therapy may worsen symptoms. Furthermore, clinicians should shy away from trial drugs with a theoretical benefit outside of a clinical trial. ●

CASE New patient presents with a history of endometrial hyperplasia

A 51-year-old patient (G2P2002) presents to a new gynecologist’s office after moving from a different state. In her medical history, the gynecologist notes that 5 years ago she underwent dilation and curettage and endometrial ablation procedures for heavy menstrual bleeding (HMB). Ultrasonography performed prior to those procedures showed a slightly enlarged uterus, a simple left ovarian cyst, and a non ̶ visualized right ovary. The patient had declined a 2-step procedure due to concerns with anesthesia, and surgical pathology at the time of ablation revealed hyperplasia without atypia. The patient’s medical history was otherwise notable for prediabetes (recent hemoglobin A_1c [HbA_1c] measurement, 6.0%) and obesity (body mass index, 43 kg/m²). Pertinent family history included her mother’s diagnosis of endometrial cancer at age 36. Given the patient’s diagnosis of endometrial hyperplasia, she was referred to gynecologic oncology, but she ultimately declined hysterectomy, stating that she was happy with the resolution of her abnormal bleeding. At the time of her initial gynecologic oncology consultation, the consultant suggested lifestyle changes to combat prediabetes and obesity to reduce the risk of endometrial cancer, as future signs of cancer, namely bleeding, may be masked by the endometrial ablation. The patient was prescribed metformin given these medical comorbidities.

At today’s appointment, the patient notes continued resolution of bleeding since the procedure. She does, however, note a 6-month history of vasomotor symptoms and one episode of spotting 3 months ago. Three years ago she was diagnosed with type 2 diabetes mellitus, and her current HbA_1c is 6.9%. She has gained 10 lb since being diagnosed with endometrial cancer 5 years ago, and she has continued to take metformin.

An in-office endometrial biopsy is unsuccessful due to cervical stenosis. The treating gynecologist orders a transvaginal ultrasound, which reveals a small left ovarian cyst and a thickened endometrium (measuring 10 mm). Concerned that these findings could represent endometrial cancer, the gynecologist refers the patient to gynecologic oncology for further evaluation.
 

Sequelae and complications following endometrial ablation are often managed by a gynecologic oncologist. Indeed, a 2018 poll of Society of Gynecologic Oncology (SGO) members revealed that 93.8% of respondents had received such a referral, and almost 20% of respondents were managing more than 20 patients with post-ablation complications in their practices.¹ These complications, including hematometra, post-ablation tubal sterilization syndrome, other pain syndromes associated with retrograde menstruation, and thickened endometrium with scarring leading to an inability to sample the endometrium to investigate post-ablation bleeding are symptoms and findings that often lead to further surgery, including hysterectomy.² General gynecologists faced with these complications may refer patients to gynecologic oncology given an inability to sample the post-ablation endometrium or anticipated difficulties with hysterectomy. A recent meta-analysis revealed a 12.4% hysterectomy rate 5 years after endometrial ablation. Among these patients, the incidence of endometrial cancer ranged from 0% to 1.6%.³

In 2023, endometrial cancer incidence continues to increase, as does the incidence of obesity in women of all ages. Endometrial cancer mortality rates are also increasing, and these trends disproportionately affects non-Hispanic Black women.⁴ As providers and advocates work to narrow these disparities, gynecologic oncologists are simultaneously noting increased referrals for very likely benign conditions.⁵ Patients referred for post-ablation bleeding are a subset of these, as most patients who undergo endometrial ablation will not develop cancer. Considering the potential bottlenecks created en route to a gynecologic oncology evaluation, it seems prudent to minimize practices, like endometrial ablation, that may directly or indirectly prevent timely referral of patients with cancer to a gynecologic oncologist.

In this review we focus on the current use of endometrial ablation, associated complications, the incidence of treatment failure, and patient selection. Considering these issues in the context of the current endometrial cancer landscape, we posit best practices aimed at optimizing patient outcomes, and empowering general gynecologists to practice cancer prevention and to triage their surgical patients.

Continue to: Current use of endometrial ablation in the US...

In 2015, more than 500,000 endometrial ablations were performed in the United States.Given the ability to perform in-office ablation, this number is growing and potentially underestimated each year.⁶ In 2022, the global endometrial ablation market was valued at $3.4 billion, a figure projected to double in 10 years.⁷ The procedure has evolved as different devices and approaches have developed, offering patients different means to manage bleeding without hysterectomy. The minimally invasive procedure, performed in premenopausal patients with heavy menstrual bleeding (HMB) due to benign causes who have completed childbearing, has been associated with faster recovery times and fewer short-term complications compared with more invasive surgery.⁸ There are several non-resectoscope ablative devices approved by the US Food and Drug Administration (FDA), and each work to destroy the endometrial lining via thermal or cryoablation. Endometrial ablation can be performed in premenopausal patients with HMB due to benign causes who have completed childbearing.

Recently, promotional literature has begun to report on so-called overuse of hysterectomy, despite decreasing overall hysterectomy rates. This reporting proposes and applies “appropriateness criteria,” accounting for the rate of preoperative counseling regarding alternatives to hysterectomy, as well as the rate of “unsupportive” final pathology.⁹ The adoption of endometrial ablation and increasing market value of such vendors suggest that this campaign is having its desired effect. From the oncology perspective, we are concerned the pendulum could swing too far away from hysterectomy, a procedure that definitively cures abnormal uterine bleeding, toward endometrial ablation without explicit acknowledgement of the trade-offs involved.

Endometrial ablation complications: Late-onset procedure failure

A number of post-ablation syndromes may present at least 1 month following the procedure. Collectively known as late-onset endometrial ablation failure (LOEAF), these syndromes are characterized by recurrent vaginal bleeding, and/or new cyclic pelvic pain.¹⁰ It is difficult to measure the true incidence of LOEAF. Thomassee and colleagues examined a Canadian retrospective cohort of 437 patients who underwent endometrial ablation; 20.8% reported post-ablation pelvic pain after a median 301 days.¹¹ The subsequent need for surgical intervention, often hysterectomy, is a surrogate for LOEAF.

It should be noted that LOEAF is distinct from post-ablation tubal sterilization syndrome (PATSS), which describes cornual menstrual bleeding impeded by the ligated proximal fallopian tube.¹² Increased awareness of PATSS, along with the discontinuation of Essure (a permanent hysteroscopic sterilization device) in 2018, has led some surgeons to advocate for concomitant salpingectomy at the time of endometrial ablation.¹³ The role of opportunistic salpingectomy in primary prevention of epithelial ovarian cancer is well described, and while we strongly support this practice at the time of endometrial ablation, we do not feel that it effectively prevents LOEAF.¹⁴

The post-ablation inability to adequately sample the endometrium is also considered a LOEAF. A prospective study of 57 women who underwent endometrial ablation assessed post-ablation sampling feasibility via transvaginal ultrasonography, saline infusion sonohysterography (SIS), and in-office endometrial biopsies. In 23% of the cohort, endometrial sampling failed, and the authors noted decreased reliability of pathologic assessment.¹⁵ One systematic review, in which authors examined the incidence of endometrial cancer following endometrial ablation, characterized 38 cases of endometrial cancer and reported a post-ablation endometrial sampling success rate of 89%. This figure was based on a self-selected sample of 18 patients; cases in which endometrial sampling was thought to be impossible were excluded. The study also had a 30% missing data rate and several other biases.¹⁶

In the previously mentioned poll of SGO members,¹ 84% of the surveyed gynecologic oncologists managing post-ablation patients reported that endometrial sampling following endometrial ablation was “moderately” or “extremely” difficult. More than half of the survey respondents believed that hysterectomy was required for accurate diagnosis.¹ While we acknowledge the likely sampling bias affecting the survey results, we are not comforted by any data that minimizes this diagnostic challenge.

Appropriate patient selection and contraindications

The ideal candidate for endometrial ablation is a premenopausal patient with HMB who does not desire future fertility. According to the FDA, absolute contraindications include pregnancy or desired fertility, prior ablation, current IUD in place, inadequate preoperative endometrial assessment, known or suspected malignancy, active infection, or unfavorable anatomy.¹⁷

What about patients who may be at increased risk for endometrial cancer?

There is a paucity of data regarding the safety of endometrial ablation in patients at increased risk for developing endometrial cancer in the future. The American College of Obstetricians and Gynecologists (ACOG) 2007 practice bulletin on endometrial ablation (no longer accessible online) alludes to this concern and other contraindications,¹⁸ but there are no established guidelines. Currently, no ACOG practice bulletin or committee opinion lists relative contraindications to endometrial ablation, long-term complications (except risks associated with future pregnancy), or risk of subsequent hysterectomy. The risk that “it may be harder to detect endometrial cancer after ablation” is noted on ACOG’s web page dedicated to frequently asked questions (FAQs) regarding abnormal uterine bleeding.¹⁹ It is not mentioned on their web page dedicated to the FAQs regarding endometrial ablation.²⁰

In the absence of high-quality published data on established contraindications for endometrial ablation, we advocate for the increased awareness of possible relative contraindications—namely well-established risk factors for endometrial cancer (TABLE 1).For example, in a pooled analysis of 24 epidemiologic studies, authors found that the odds of developing endometrial cancer was 7 times higher among patients with a body mass index (BMI) ≥ 40 kg/m², compared with controls (odds ratio [OR], 7.14; 95% confidence interval [CI], 6.33–8.06).²¹ Additionally, patients with Lynch syndrome, a history of extended tamoxifen use, or those with a history of chronic anovulation or polycystic ovary syndrome are at increased risk for endometrial cancer.^22-24 If the presence of one or more of these factors does not dissuade general gynecologists from performing an endometrial ablation (even armed with a negative preoperative endometrial biopsy), we feel they should at least prompt thoughtful guideline-driven pause.

Hysterectomy—A disincentivized option

The annual number of hysterectomies performed by general gynecologists has declined over time. One study by Cadish and colleagues revealed that recent residency graduates performed only 3 to 4 annually.²⁵ These numbers partly reflect the decreasing number of hysterectomies performed during residency training. Furthermore, other factors—including the increasing rate of placenta accreta spectrum, the focus on risk stratification of adnexal masses via the ovarian-adnexal reporting and data classification system (O-RADs), and the emphasis on minimally invasive approaches often acquired in subspecialty training—have likely contributed to referral patterns to such specialists as minimally invasive gynecologic surgeons and gynecologic oncologists.²⁶ This trend is self-actualizing, as quality metrics funnel patients to high-volume surgeons, and general gynecologists risk losing hysterectomy privileges.

These factors lend themselves to a growing emphasis on endometrial ablation. Endometrial ablations can be performed in several settings, including in the hospital, in outpatient clinics, and more and more commonly, in ambulatory surgery centers. This increased access to endometrial ablation in the ambulatory surgery setting has corresponded with an annual endometrial ablation market value growth rate of 5% to 7%.²⁷ These rates are likely compounded by payer reimbursement policies that promote endometrial ablation and other alternatives to hysterectomy that are cost savings in the short term.²⁸ While the actual payer models are unavailable to review, they may not consider the costs of LOEAFs, including subsequent hysterectomy up to 5 years after initial ablation procedures. Provocatively, they almost certainly do not consider the costs of delayed care of patients with endometrial cancer vying for gynecologic oncology appointment slots occupied by post-ablation patients.

We urge providers, patients, and advocates to question who benefits from the uptake of ablation procedures: Patients? Payors? Providers? And how will the field of gynecology fare if hysterectomy skills and privileges are supplanted by ablation?

Post-ablation bleeding: Management by the gyn oncologist

Patients with post-ablation bleeding, either immediately or years later, are sometimes referred to a gynecologic oncologist given the possible risk for cancer and need for surgical staging if cancer is found on the hysterectomy specimen. In practice, assuming normal preoperative ultrasonography and no other clinical or radiologic findings suggestive of malignancy (eg, computed tomography findings concerning for metastases, abnormal cervical cytology, etc.), the presence of cancer is extremely unlikely to be determined at the time of surgery. Frozen section is not generally performed on the endometrium; intraoperative evaluation of even the unablated endometrium is notoriously unreliable; and histologic assessment of the ablated endometrium is limited by artifact (FIGURE 1). The abnormalities caused by ablation further impede selection of a representative focus, obfuscating any actionable result.

Some surgeons routinely bivalve the excised uterus prior to fixation to assess presence of tumor, tumor size, and the degree of myometrial invasion.²⁹ A combination of factors may compel surgeons to perform lymphadenectomy if not already performed, or if sentinel lymph node mapping was unsuccessful. But this practice has not been studied in patients with post-ablation bleeding, and applying these principles relies on a preoperative diagnosis establishing the presence and grade of a cancer. Furthermore, the utility of frozen section and myometrial assessment to decide whether or not to proceed with lymphadenectomy is less relevant in the era of molecular classification guiding adjuvant therapy. In summary, assuming no pathologic or radiologic findings suggestive of cancer, gynecologic oncologists are unlikely to perform lymphadenectomy at the time of hysterectomy in these post-ablation cases, which therefore can safely be performed by general gynecologists.

Our recommendations

Consider the LNG-IUD as an alternative to ablation. A recent randomized controlled trial by Beelen and colleagues compared the effectiveness of LNG-releasing IUDs with endometrial ablation in patients with HMB. While the LNG-IUD was inferior to endometrial ablation, quality-of-life measures were similar up to 2 years.³¹ Realizing that the hysterectomy rate following endometrial ablation increases significantly beyond that time point (2 years), this narrative may be incomplete. A 5- to 10-year follow-up time-frame may be a more helpful gauge of long-term outcomes. This prolonged time-frame also may allow study of the LNG-IUD’s protective effects on the endometrium in the prevention of endometrial hyperplasia and cancer.

Consider hysterectomy. A 2021 Cochrane review revealed that, compared with endometrial ablation, minimally invasive hysterectomy is associated with higher quality-of-life metrics, higher self-reported patient satisfaction, and similar rates of adverse events.³² While patient autonomy is paramount, the developing step-wise approach from endometrial ablation to hysterectomy, and its potential effects on the health care system at a time when endometrial cancer incidence and mortality rates are rising, is troubling.

Postablation, consider hysterectomy by the general gynecologist. Current trends appear to disincentivize general gynecologists from performing hysterectomy either for HMB or LOEAF. We would offer reassurance that they can safely perform this procedure. Referral to oncology may not be necessary since, in the absence of an established diagnosis of cancer, a lymphadenectomy is not typically required. A shift away from referral for these patients can preserve access to oncology for those women, especially minority women, with an explicit need for oncologic care.

In FIGURE 2, we propose a management algorithm for the patient who presents with post–ablation bleeding. We acknowledge that the evidence base for our management recommendations is limited. Still, we hope providers, ACOG, and other guidelines-issuing organizations consider them as they adapt their own practices and recommendations. We believe this is one of many steps needed to improve outcomes for patients with gynecologic cancer, particularly those in marginalized communities disproportionately impacted by current trends.

CASE Resolution

After reviewing the relevant documentation and examining the patient, the gynecologic oncology consultant contacts the referring gynecologist. They review the low utility of frozen section and the overall low risk of cancer on the final hysterectomy specimen if the patient were to undergo hysterectomy. The consultant clarifies that there is no other concern for surgical complexity beyond the skill of the referring provider, and they discuss the possibility of referral to a minimally invasive specialist for the surgery.

Ultimately, the patient undergoes uncomplicated laparoscopic hysterectomy performed by the original referring gynecologist. Final pathology reveals inactive endometrium with ablative changes and cornual focus of endometrial hyperplasia without atypia. ●

While the LNG-IUD was inferior to endometrial ablation, quality-of-life measures were similar up to 2 years.³¹ Realizing that the hysterectomy rate following endometrial ablation increases significantly beyond that time point (2 years), this narrative may be incomplete. A 5- to 10-year follow-up time-frame may be a more helpful gauge of long-term outcomes. This prolonged time-frame also may allow study of the LNG-IUD’s protective effects on the endometrium in the prevention of endometrial hyperplasia and cancer.

Consider hysterectomy. A 2021 Cochrane review revealed that, compared with endometrial ablation, minimally invasive hysterectomy is associated with higher quality-of-life metrics, higher self-reported patient satisfaction, and similar rates of adverse events.³² While patient autonomy is paramount, the developing step-wise approach from endometrial ablation to hysterectomy, and its potential effects on the health care system at a time when endometrial cancer incidence and mortality rates are rising, is troubling.

Postablation, consider hysterectomy by the general gynecologist. Current trends appear to disincentivize general gynecologists from performing hysterectomy either for HMB or LOEAF. We would offer reassurance that they can safely perform this procedure. Referral to oncology may not be necessary since, in the absence of an established diagnosis of cancer, a lymphadenectomy is not typically required. A shift away from referral for these patients can preserve access to oncology for those women, especially minority women, with an explicit need for oncologic care.

In FIGURE 2, we propose a management algorithm for the patient who presents with post–ablation bleeding. We acknowledge that the evidence base for our management recommendations is limited. Still, we hope providers, ACOG, and other guidelines-issuing organizations consider them as they adapt their own practices and recommendations. We believe this is one of many steps needed to improve outcomes for patients with gynecologic cancer, particularly those in marginalized communities disproportionately impacted by current trends.

CASE Resolution

After reviewing the relevant documentation and examining the patient, the gynecologic oncology consultant contacts the referring gynecologist. They review the low utility of frozen section and the overall low risk of cancer on the final hysterectomy specimen if the patient were to undergo hysterectomy. The consultant clarifies that there is no other concern for surgical complexity beyond the skill of the referring provider, and they discuss the possibility of referral to a minimally invasive specialist for the surgery.

Ultimately, the patient undergoes uncomplicated laparoscopic hysterectomy performed by the original referring gynecologist. Final pathology reveals inactive endometrium with ablative changes and cornual focus of endometrial hyperplasia without atypia. ●

CASE New patient presents with a history of endometrial hyperplasia

A 51-year-old patient (G2P2002) presents to a new gynecologist’s office after moving from a different state. In her medical history, the gynecologist notes that 5 years ago she underwent dilation and curettage and endometrial ablation procedures for heavy menstrual bleeding (HMB). Ultrasonography performed prior to those procedures showed a slightly enlarged uterus, a simple left ovarian cyst, and a non ̶ visualized right ovary. The patient had declined a 2-step procedure due to concerns with anesthesia, and surgical pathology at the time of ablation revealed hyperplasia without atypia. The patient’s medical history was otherwise notable for prediabetes (recent hemoglobin A_1c [HbA_1c] measurement, 6.0%) and obesity (body mass index, 43 kg/m²). Pertinent family history included her mother’s diagnosis of endometrial cancer at age 36. Given the patient’s diagnosis of endometrial hyperplasia, she was referred to gynecologic oncology, but she ultimately declined hysterectomy, stating that she was happy with the resolution of her abnormal bleeding. At the time of her initial gynecologic oncology consultation, the consultant suggested lifestyle changes to combat prediabetes and obesity to reduce the risk of endometrial cancer, as future signs of cancer, namely bleeding, may be masked by the endometrial ablation. The patient was prescribed metformin given these medical comorbidities.

At today’s appointment, the patient notes continued resolution of bleeding since the procedure. She does, however, note a 6-month history of vasomotor symptoms and one episode of spotting 3 months ago. Three years ago she was diagnosed with type 2 diabetes mellitus, and her current HbA_1c is 6.9%. She has gained 10 lb since being diagnosed with endometrial cancer 5 years ago, and she has continued to take metformin.

An in-office endometrial biopsy is unsuccessful due to cervical stenosis. The treating gynecologist orders a transvaginal ultrasound, which reveals a small left ovarian cyst and a thickened endometrium (measuring 10 mm). Concerned that these findings could represent endometrial cancer, the gynecologist refers the patient to gynecologic oncology for further evaluation.
 

Sequelae and complications following endometrial ablation are often managed by a gynecologic oncologist. Indeed, a 2018 poll of Society of Gynecologic Oncology (SGO) members revealed that 93.8% of respondents had received such a referral, and almost 20% of respondents were managing more than 20 patients with post-ablation complications in their practices.¹ These complications, including hematometra, post-ablation tubal sterilization syndrome, other pain syndromes associated with retrograde menstruation, and thickened endometrium with scarring leading to an inability to sample the endometrium to investigate post-ablation bleeding are symptoms and findings that often lead to further surgery, including hysterectomy.² General gynecologists faced with these complications may refer patients to gynecologic oncology given an inability to sample the post-ablation endometrium or anticipated difficulties with hysterectomy. A recent meta-analysis revealed a 12.4% hysterectomy rate 5 years after endometrial ablation. Among these patients, the incidence of endometrial cancer ranged from 0% to 1.6%.³

In 2023, endometrial cancer incidence continues to increase, as does the incidence of obesity in women of all ages. Endometrial cancer mortality rates are also increasing, and these trends disproportionately affects non-Hispanic Black women.⁴ As providers and advocates work to narrow these disparities, gynecologic oncologists are simultaneously noting increased referrals for very likely benign conditions.⁵ Patients referred for post-ablation bleeding are a subset of these, as most patients who undergo endometrial ablation will not develop cancer. Considering the potential bottlenecks created en route to a gynecologic oncology evaluation, it seems prudent to minimize practices, like endometrial ablation, that may directly or indirectly prevent timely referral of patients with cancer to a gynecologic oncologist.

In this review we focus on the current use of endometrial ablation, associated complications, the incidence of treatment failure, and patient selection. Considering these issues in the context of the current endometrial cancer landscape, we posit best practices aimed at optimizing patient outcomes, and empowering general gynecologists to practice cancer prevention and to triage their surgical patients.

Continue to: Current use of endometrial ablation in the US...

In 2015, more than 500,000 endometrial ablations were performed in the United States.Given the ability to perform in-office ablation, this number is growing and potentially underestimated each year.⁶ In 2022, the global endometrial ablation market was valued at $3.4 billion, a figure projected to double in 10 years.⁷ The procedure has evolved as different devices and approaches have developed, offering patients different means to manage bleeding without hysterectomy. The minimally invasive procedure, performed in premenopausal patients with heavy menstrual bleeding (HMB) due to benign causes who have completed childbearing, has been associated with faster recovery times and fewer short-term complications compared with more invasive surgery.⁸ There are several non-resectoscope ablative devices approved by the US Food and Drug Administration (FDA), and each work to destroy the endometrial lining via thermal or cryoablation. Endometrial ablation can be performed in premenopausal patients with HMB due to benign causes who have completed childbearing.

Recently, promotional literature has begun to report on so-called overuse of hysterectomy, despite decreasing overall hysterectomy rates. This reporting proposes and applies “appropriateness criteria,” accounting for the rate of preoperative counseling regarding alternatives to hysterectomy, as well as the rate of “unsupportive” final pathology.⁹ The adoption of endometrial ablation and increasing market value of such vendors suggest that this campaign is having its desired effect. From the oncology perspective, we are concerned the pendulum could swing too far away from hysterectomy, a procedure that definitively cures abnormal uterine bleeding, toward endometrial ablation without explicit acknowledgement of the trade-offs involved.

Endometrial ablation complications: Late-onset procedure failure

A number of post-ablation syndromes may present at least 1 month following the procedure. Collectively known as late-onset endometrial ablation failure (LOEAF), these syndromes are characterized by recurrent vaginal bleeding, and/or new cyclic pelvic pain.¹⁰ It is difficult to measure the true incidence of LOEAF. Thomassee and colleagues examined a Canadian retrospective cohort of 437 patients who underwent endometrial ablation; 20.8% reported post-ablation pelvic pain after a median 301 days.¹¹ The subsequent need for surgical intervention, often hysterectomy, is a surrogate for LOEAF.

It should be noted that LOEAF is distinct from post-ablation tubal sterilization syndrome (PATSS), which describes cornual menstrual bleeding impeded by the ligated proximal fallopian tube.¹² Increased awareness of PATSS, along with the discontinuation of Essure (a permanent hysteroscopic sterilization device) in 2018, has led some surgeons to advocate for concomitant salpingectomy at the time of endometrial ablation.¹³ The role of opportunistic salpingectomy in primary prevention of epithelial ovarian cancer is well described, and while we strongly support this practice at the time of endometrial ablation, we do not feel that it effectively prevents LOEAF.¹⁴

The post-ablation inability to adequately sample the endometrium is also considered a LOEAF. A prospective study of 57 women who underwent endometrial ablation assessed post-ablation sampling feasibility via transvaginal ultrasonography, saline infusion sonohysterography (SIS), and in-office endometrial biopsies. In 23% of the cohort, endometrial sampling failed, and the authors noted decreased reliability of pathologic assessment.¹⁵ One systematic review, in which authors examined the incidence of endometrial cancer following endometrial ablation, characterized 38 cases of endometrial cancer and reported a post-ablation endometrial sampling success rate of 89%. This figure was based on a self-selected sample of 18 patients; cases in which endometrial sampling was thought to be impossible were excluded. The study also had a 30% missing data rate and several other biases.¹⁶

In the previously mentioned poll of SGO members,¹ 84% of the surveyed gynecologic oncologists managing post-ablation patients reported that endometrial sampling following endometrial ablation was “moderately” or “extremely” difficult. More than half of the survey respondents believed that hysterectomy was required for accurate diagnosis.¹ While we acknowledge the likely sampling bias affecting the survey results, we are not comforted by any data that minimizes this diagnostic challenge.

Appropriate patient selection and contraindications

The ideal candidate for endometrial ablation is a premenopausal patient with HMB who does not desire future fertility. According to the FDA, absolute contraindications include pregnancy or desired fertility, prior ablation, current IUD in place, inadequate preoperative endometrial assessment, known or suspected malignancy, active infection, or unfavorable anatomy.¹⁷

What about patients who may be at increased risk for endometrial cancer?

There is a paucity of data regarding the safety of endometrial ablation in patients at increased risk for developing endometrial cancer in the future. The American College of Obstetricians and Gynecologists (ACOG) 2007 practice bulletin on endometrial ablation (no longer accessible online) alludes to this concern and other contraindications,¹⁸ but there are no established guidelines. Currently, no ACOG practice bulletin or committee opinion lists relative contraindications to endometrial ablation, long-term complications (except risks associated with future pregnancy), or risk of subsequent hysterectomy. The risk that “it may be harder to detect endometrial cancer after ablation” is noted on ACOG’s web page dedicated to frequently asked questions (FAQs) regarding abnormal uterine bleeding.¹⁹ It is not mentioned on their web page dedicated to the FAQs regarding endometrial ablation.²⁰

In the absence of high-quality published data on established contraindications for endometrial ablation, we advocate for the increased awareness of possible relative contraindications—namely well-established risk factors for endometrial cancer (TABLE 1).For example, in a pooled analysis of 24 epidemiologic studies, authors found that the odds of developing endometrial cancer was 7 times higher among patients with a body mass index (BMI) ≥ 40 kg/m², compared with controls (odds ratio [OR], 7.14; 95% confidence interval [CI], 6.33–8.06).²¹ Additionally, patients with Lynch syndrome, a history of extended tamoxifen use, or those with a history of chronic anovulation or polycystic ovary syndrome are at increased risk for endometrial cancer.^22-24 If the presence of one or more of these factors does not dissuade general gynecologists from performing an endometrial ablation (even armed with a negative preoperative endometrial biopsy), we feel they should at least prompt thoughtful guideline-driven pause.

Continue to: Hysterectomy—A disincentivized option...

Hysterectomy—A disincentivized option

The annual number of hysterectomies performed by general gynecologists has declined over time. One study by Cadish and colleagues revealed that recent residency graduates performed only 3 to 4 annually.²⁵ These numbers partly reflect the decreasing number of hysterectomies performed during residency training. Furthermore, other factors—including the increasing rate of placenta accreta spectrum, the focus on risk stratification of adnexal masses via the ovarian-adnexal reporting and data classification system (O-RADs), and the emphasis on minimally invasive approaches often acquired in subspecialty training—have likely contributed to referral patterns to such specialists as minimally invasive gynecologic surgeons and gynecologic oncologists.²⁶ This trend is self-actualizing, as quality metrics funnel patients to high-volume surgeons, and general gynecologists risk losing hysterectomy privileges.

These factors lend themselves to a growing emphasis on endometrial ablation. Endometrial ablations can be performed in several settings, including in the hospital, in outpatient clinics, and more and more commonly, in ambulatory surgery centers. This increased access to endometrial ablation in the ambulatory surgery setting has corresponded with an annual endometrial ablation market value growth rate of 5% to 7%.²⁷ These rates are likely compounded by payer reimbursement policies that promote endometrial ablation and other alternatives to hysterectomy that are cost savings in the short term.²⁸ While the actual payer models are unavailable to review, they may not consider the costs of LOEAFs, including subsequent hysterectomy up to 5 years after initial ablation procedures. Provocatively, they almost certainly do not consider the costs of delayed care of patients with endometrial cancer vying for gynecologic oncology appointment slots occupied by post-ablation patients.

We urge providers, patients, and advocates to question who benefits from the uptake of ablation procedures: Patients? Payors? Providers? And how will the field of gynecology fare if hysterectomy skills and privileges are supplanted by ablation?

Post-ablation bleeding: Management by the gyn oncologist

Patients with post-ablation bleeding, either immediately or years later, are sometimes referred to a gynecologic oncologist given the possible risk for cancer and need for surgical staging if cancer is found on the hysterectomy specimen. In practice, assuming normal preoperative ultrasonography and no other clinical or radiologic findings suggestive of malignancy (eg, computed tomography findings concerning for metastases, abnormal cervical cytology, etc.), the presence of cancer is extremely unlikely to be determined at the time of surgery. Frozen section is not generally performed on the endometrium; intraoperative evaluation of even the unablated endometrium is notoriously unreliable; and histologic assessment of the ablated endometrium is limited by artifact (FIGURE 1). The abnormalities caused by ablation further impede selection of a representative focus, obfuscating any actionable result.

Some surgeons routinely bivalve the excised uterus prior to fixation to assess presence of tumor, tumor size, and the degree of myometrial invasion.²⁹ A combination of factors may compel surgeons to perform lymphadenectomy if not already performed, or if sentinel lymph node mapping was unsuccessful. But this practice has not been studied in patients with post-ablation bleeding, and applying these principles relies on a preoperative diagnosis establishing the presence and grade of a cancer. Furthermore, the utility of frozen section and myometrial assessment to decide whether or not to proceed with lymphadenectomy is less relevant in the era of molecular classification guiding adjuvant therapy. In summary, assuming no pathologic or radiologic findings suggestive of cancer, gynecologic oncologists are unlikely to perform lymphadenectomy at the time of hysterectomy in these post-ablation cases, which therefore can safely be performed by general gynecologists.

Our recommendations

Consider the LNG-IUD as an alternative to ablation. A recent randomized controlled trial by Beelen and colleagues compared the effectiveness of LNG-releasing IUDs with endometrial ablation in patients with HMB. While the LNG-IUD was inferior to endometrial ablation, quality-of-life measures were similar up to 2 years.³¹ Realizing that the hysterectomy rate following endometrial ablation increases significantly beyond that time point (2 years), this narrative may be incomplete.

While chimeric antigen receptor (CAR) T-cell therapy has transformed the management of large B-cell lymphoma (LBCL), the majority of patients will ultimately relapse. Efforts to identify predictors of response remain an active area of investigation. One key variable that has been postulated to influence CAR T-cell outcomes is pretreatment bendamustine exposure. Specifically, there has been concern that the lymphodepleting effects of bendamustine could affect T-cell fitness, thus impairing CAR T-cell response. While consensus guidelines have recommended avoiding bendamustine prior to lymphocyte collection, clear data have been lacking. A recent retrospective, multicenter study, which included patients from seven European sites, reported outcomes based on prior bendamustine exposure (Iacoboni et al). In this study, 439 patients with relapsed or refractory LBCL, who received anti-CD19 commercial CAR T-cell therapy after two or more prior treatment lines of therapy, were included. Of these patients, 80 had received prior bendamustine. The authors found that patients recently exposed to bendamustine (< 9 months), vs bendamustine-naive patients, had a significantly lower overall response rate (40% vs 66%; P = .01), overall survival (OS; adjusted hazard ratio [aHR] 2.11; P < .01), and progression-free survival (PFS; aHR 1.82; P < .01) after CAR T-cell infusion. These differences remained significant after inverse probability treatment weighting and propensity score matching. Of note, the authors did not find that the cumulative dose of bendamustine affected outcomes. The authors also identified that, while the risk for cytokine release syndrome and immune effector cell–associated neurotoxicity syndrome was similar between the groups, hematologic toxicity and severe infections were increased in the bendamustine-exposed patients. These data support the recommendation to avoid bendamustine treatment prior to CAR T-cell apheresis. While treatment regimens such as polatuzumab plus bendamustine and rituximab are available in the relapsed setting for LBCL,¹ this regimen should be reserved for post CAR T-cell relapse or for patients not planning to proceed with cellular therapy. The impact of bendamustine exposure on other immune-mediated therapies, such as bispecific antibodies, remains unknown.

Quantitative PET/CT biomarkers have also emerged as predictors of response in diffuse large B-cell lymphoma (DLBCL). A key variable of interest includes total metabolic tumor volume (MTV), which refers to the total volume of tumor with metabolic uptake. While prior studies have demonstrated a correlation of MTV on outcomes following treatment with chemotherapy and CAR T-cell therapy,^2,3 the effect of PET/CT biomarkers on outcomes with other novel agents remains poorly described. A recent study by Alderuccio and colleagues explored the predictive power of PET/CT biomarkers on outcomes in a clinical trial cohort of patients treated with the antibody drug conjugate loncastuximab tesirine. This post hoc analysis reviewed the screening PET/CT scans of 138 patients with relapsed or refractory DLBCL treated with two or more prior systemic therapy lines who received loncastuximab tesirine in LOTIS-2<.⁴ The authors found that an MTV ≥ 96 mL was significantly associated with failure to achieve a complete metabolic response (adjusted odds ratio 5.42; P = .002). Patients with an MTV ≥ 96 mL vs < 96 mL also had a shorter PFS (aHR 2.68; P = .002) and OS (aHR 3.09; P < .0001). In line with prior studies, this analysis demonstrates that baseline MTV has the potential to provide robust risk-stratification and confirms the value of PET/CT biomarkers in DLBCL across treatment types.

This month, the results of the phase 2 TARMAC study, which evaluated treatment with ibrutinib in combination with tisagenlecleucel, were also published. This study included 20 patients with relapsed/refractory mantle cell lymphoma (MCL) who had received one or more prior lines of therapy, including 50% with prior Bruton tyrosine kinase inhibitor (BTKi) exposure. Ibrutinib was initiated prior to leukapheresis and continued through CAR T-cell manufacturing and for at least 6 months post tisagenlecleucel infusion. At 4 months post infusion, the overall and complete response rates were 80% each. Patients without and with prior BTKi exposure had complete response rates of 90% and 70%, respectively. At a median follow-up of 13 months, the estimated 12-month PFS was 75% and OS was 100%. Grades 1-2 and grade 3 cytokine-release syndrome rates were 55% and 20%, respectively, and grade 1-2 immune effector cell–associated neurotoxicity syndrome was seen in 10% of patients. The authors also demonstrated that markers of T-cell exhaustion were decreased in patients with longer ibrutinib exposure prior to leukapheresis. Also of note, the three patients with recent bendamustine therapy did not receive a durable response. Although this is a small study without a control arm, this study provides rationale for the potential advantage of combining BTKi with CAR T-cell therapy, even among patients with prior BTKi exposure.

A key variable of interest includes total metabolic tumor volume (MTV), which refers to the total volume of tumor with metabolic uptake. While prior studies have demonstrated a correlation of MTV on outcomes following treatment with chemotherapy and CAR T-cell therapy,^2,3 the effect of PET/CT biomarkers on outcomes with other novel agents remains poorly described. A recent study by Alderuccio and colleagues explored the predictive power of PET/CT biomarkers on outcomes in a clinical trial cohort of patients treated with the antibody drug conjugate loncastuximab tesirine. This post hoc analysis reviewed the screening PET/CT scans of 138 patients with relapsed or refractory DLBCL treated with two or more prior systemic therapy lines who received loncastuximab tesirine in LOTIS-2<.⁴ The authors found that an MTV ≥ 96 mL was significantly associated with failure to achieve a complete metabolic response (adjusted odds ratio 5.42; P = .002). Patients with an MTV ≥ 96 mL vs < 96 mL also had a shorter PFS (aHR 2.68; P = .002) and OS (aHR 3.09; P < .0001). In line with prior studies, this analysis demonstrates that baseline MTV has the potential to provide robust risk-stratification and confirms the value of PET/CT biomarkers in DLBCL across treatment types.

This month, the results of the phase 2 TARMAC study, which evaluated treatment with ibrutinib in combination with tisagenlecleucel, were also published. This study included 20 patients with relapsed/refractory mantle cell lymphoma (MCL) who had received one or more prior lines of therapy, including 50% with prior Bruton tyrosine kinase inhibitor (BTKi) exposure. Ibrutinib was initiated prior to leukapheresis and continued through CAR T-cell manufacturing and for at least 6 months post tisagenlecleucel infusion. At 4 months post infusion, the overall and complete response rates were 80% each. Patients without and with prior BTKi exposure had complete response rates of 90% and 70%, respectively. At a median follow-up of 13 months, the estimated 12-month PFS was 75% and OS was 100%. Grades 1-2 and grade 3 cytokine-release syndrome rates were 55% and 20%, respectively, and grade 1-2 immune effector cell–associated neurotoxicity syndrome was seen in 10% of patients. The authors also demonstrated that markers of T-cell exhaustion were decreased in patients with longer ibrutinib exposure prior to leukapheresis. Also of note, the three patients with recent bendamustine therapy did not receive a durable response. Although this is a small study without a control arm, this study provides rationale for the potential advantage of combining BTKi with CAR T-cell therapy, even among patients with prior BTKi exposure.

The association of rheumatoid arthritis (RA) with increased cancer risk compared with the general population has long been known, though the balance between risk related to RA disease activity compared with risk related to immunosuppressive medication has not been clear. This increased risk is seen primarily with lymphoma and lung cancer, and prior research has suggested a risk with biological disease-modifying antirheumatic drugs (bDMARD), such as anti–tumor necrosis factor (TNF) agents. Beydon and colleagues performed a cohort study using a French national claims database; they looked at patients seen for at least 1 year with treatment for RA and compared the incidence of cancer by type. In over 257,000 patients, nearly 24,000 cancer cases were found. The most common cancers were breast, colon, lung, and prostate. All-cancer risk was > 1.2 (standardized incidence ratio) compared with those without cancer, higher in men compared with women, and the risk was increased in patients who received conventional synthetic (cs) DMARD, TNF inhibitors (TNFi), abatacept, and rituximab, but not interleukin (IL)-6 inhibitors or Janus kinase inhibitors (JAKi). Given that the risk was most highly associated with exposure to rituximab, this may show a type of bias rendering the study difficult to interpret, as rituximab is considered "safe" in cancer, and treatments such as csDMARD may have been given because they were not contraindicated in patients with cancer. This renders the study’s other results, such as lower risk with JAKi or higher risk with abatacept, hard to interpret.

Hayashi and colleagues performed a "real-world" comparative study using data from the Japanese observational ANSWER registry database to compare effectiveness of different JAKi over 6 months, a question of high interest given the availability of several JAKi currently. Within the database of over 11,000 participants, only 622 patients were exposed to tofacitinib, baricitinib, peficitinib, or upadacitinib, with 361 included in the final analysis due to missing baseline data (later missing data were imputed). Treatment retention rates were similar among all four JAKi, and discontinuation rates due to adverse events and due to lack of efficacy were similar as well. There was no significant difference in Health Assessment Questionnaire (HAQ), Clinical Disease Activity Index (CDAI), or C-reactive protein after 6 months between the four JAKi. Baricitinib had higher rates of CDAI low disease activity and remission at 6 months when used as a first-line biologic/targeted synthetic (b/ts) DMARD. However, this and other specific findings related to individual JAKi may be affected by the relatively small number of patients included and exposed to each JAKi, and the relatively short duration of follow-up (in terms of drug discontinuation), thus countering the initial premise for the study.

Finally, another important real-world study, by Tageldin and colleagues, looked at tapering therapy in the Rheumatoid Arthritis Medication Tapering (RHEUMTAP) cohort of patients with RA in sustained disease remission or low disease activity for at least 6 months on stable medications (infused bDMARD excluded). This 2-year prospective cohort included reducing frequency, reducing dose, and stopping medication according to predefined regimens. Of 131 patients, 40% underwent tapering, with more flares in the taper group over > 400 days of follow-up; flare rates were much higher in those tapering b/tsDMARD compared with csDMARD. Though limited by small numbers in examining the three different tapering groups, this real-world study provides an important counterpoint to the notion that medication can be tapered easily in RA patients doing well. A more stringent definition or longer duration of disease remission may also affect this finding.

Depression is one of the most common comorbidities associated with migraine. Major depressive disorder is both a risk factor for chronic migraine and a condition that one is more likely to develop after being diagnosed with chronic migraine. The study by de Vries Lentsch and colleagues investigated the use of two of the calcitonin gene-related peptide (CGRP) monoclonal antibody (mAb) treatments — erenumab and fremanezumab — compared with a control group of patients with chronic migraine, with an eye on outcomes to measure depression. Of note, reduction in headache frequency (defined as reduction in monthly migraine days) was also investigated as an independent variable.

This was a single-center study performed at the University of Leiden Headache Center. It was not a randomized trial, but all patients were followed with an e-diary and Day 0 vs Day 90 questionnaires that tracked their headache frequency and severity as well as a number of metrics related to depression. Depressive symptoms were assessed using the Hospital Anxiety and Depression Scale (HADS) and the Center for Epidemiological Studies Depression Scale (CES-D). The Headache Impact Test (HIT-6) was used to follow headache-related impact and disability, and the Perceived Stress Scale (PSS) was used to measure the degree of stressful situations the patient was experiencing.

The baseline depression scales between the three groups were 70%, 60%, and 66%, respectively; there were similar baseline levels of migraine frequency and disability as well. Both intervention groups showed a significant decrease in the symptoms of depression, and having a greater level of depression was negatively associated with reduction in monthly migraine days after 3 months. Of note, logistic-regression analysis determined that the reduction in depressive symptoms was independent of the reduction in migraine frequency.

Nearly all headache care providers are faced with challenging situations on a daily basis; often this is due to the comorbidity of mood disorders and high-frequency migraine. A traditional approach has been to provide the patient with a migraine preventive medication in the antidepressant family, such as a tricyclic antidepressant or serotonin and norepinephrine reuptake inhibitor (SNRI). Although these can be helpful, they are less specific for migraine prevention. Many patients are also already taking antidepressant medications, and the addition of a migraine-preventive antidepressant would be contraindicated. This study broadens the possibilities for prevention in these complicated patients and shows that there is benefit in both migraine-related outcomes and markers for depression when using CGRP-based therapy.

The way headache medicine is practiced changed dramatically in 2018 with the advent of CGRP monoclonal antibody (mAb) treatments for migraine. These medications have allowed us to target migraine specifically, whereas all of the preventive medications for migraine prior to 2018 were developed for other conditions and only secondarily helped migraine. These include the antidepressant, antihypertensive, and antiepileptic classes of medications, as well as onabotulinum toxin A, which, although approved for migraine, is not targeting a migraine-specific factor. Moskatel and colleagues sought to better understand the changing patterns of prescribing the nonspecific, or "traditional," migraine preventive medications in light of the advent of CGRP treatment.

This was a retrospective cohort study using aggregated data from the Stanford headache center. The percentage of patients with chronic migraine who had been prescribed one of the 10 most prescribed oral preventive medications or onabotulinum toxin A, or any of the four CGRP mAb, were calculated relative to the total number of patients with chronic migraine who received a prescription for any medication from the clinic during the pre-CGRP mAb years of 2015-2017 and post-approval years of 2019-2021.

The Stanford (STARR) database was filtered, searching for patients living in a California ZIP code with a diagnosis of chronic migraine who were followed from 2015 to 2021. The 10 most common non-CGRP preventive medications were amitriptyline/nortriptyline, valproate, duloxetine, gabapentin, memantine, propranolol, venlafaxine, verapamil, and onabotulinumtoxinA.

Erenumab was noted to initially be the most prescribed CGRP monoclonal antibody medication, but this was overtaken by galcanezumab after the second quarter of 2020 and throughout 2021. There is a statistically significant decrease in the percentage of patients receiving any of the non-CGRP preventive medications since 2018. The most significant decreases were in the tricyclic antidepressant class, as well as valproate, duloxetine, memantine, and onabotulinum toxin A. There was no statistically significant change in venlafaxine or gabapentin prescriptions.

This study highlights the changing face of headache medicine, and having a new class of migraine-specific treatment has significantly affected prescribing patterns. Although there is a statistically significant decrease in the prescribing of these non–migraine-specific preventive medications, they are still often recommended due to step-therapy regulations from insurance formularies, or as part of a polypharmacy regimen that may be more beneficial for a patient. These medications do improve patient outcomes and will remain a mainstay in migraine treatment.

Nearly all patients with migraine are recommended an acute medication to treat migraine attacks abortively; some patients are also recommended preventive therapies if migraine frequency significantly affects their quality of life. The American Headache Society/American Academy of Neurology guidelines for prevention recommend the initiation of a preventive medication at a frequency of 4-5 headache days per month or approximately 1 per week. Lipton and colleagues sought to determine whether there were any efficacy concerns in combining a CGRP mAb for prevention with ubrogepant, an oral CGRP antagonist, for acute treatment.

This was a prospective, open-level observational study assessing pain relief, return to normal function, and treatment satisfaction with patients given 50 or 100 mg of ubrogepant while concomitantly being given a seizure or mAb medication. Patients were allowed to be taking onabotulinumtoxinA as well as a CGRP mAb. The patients in this study were asked to track their headache symptoms using the Migraine Buddy e-diary. Meaningful pain relief was defined as a rating of migraine-related pain with one of the following choices 4 hours after taking the medication: no pain, mild pain, moderate pain, or severe pain. Return to normal function was defined as whether the patient determined they were able to function normally relative to their baseline at specific times post intervention. This was based on a functional disability scale. Treatment satisfaction was determined on the basis of a seven-point rating scale for how satisfied the patient felt with the medication at the end of the trial period.

A total of 245 participants provided at least 30 days of data, with 44.5% of the patients taking erenumab, 35.1% taking galcanezumab, 18.0% taking fremanezumab, and 2.9% taking eptinezumab. Meaningful pain relief was achieved by 61.6% of patients at 2 hours and 80.4% of patients at 4 hours post dose for both the 50-mg and 100-mg dose of ubrogepant. Return to normal function was achieved by 34.7% of patients at 2 hours and 50.5% at 4 hours post dose as well. Patients reported a 72.7% satisfaction level with the medication.

When CGRP acute medications were first approved, there was concern about the use of a mAb together with an oral antagonist. It was thought that CGRP medications would be associated with fewer benefits than when these medications were used alone, due to the belief that only a specific amount of CGRP could be blocked at any specific time. This trial shows that the efficacy of CGRP acute medications is not affected by concomitant use of mAb. Many patients who respond well to CGRP mAb will benefit significantly from the additional abortive use of oral antagonists.

There was no statistically significant change in venlafaxine or gabapentin prescriptions.

This study highlights the changing face of headache medicine, and having a new class of migraine-specific treatment has significantly affected prescribing patterns. Although there is a statistically significant decrease in the prescribing of these non–migraine-specific preventive medications, they are still often recommended due to step-therapy regulations from insurance formularies, or as part of a polypharmacy regimen that may be more beneficial for a patient. These medications do improve patient outcomes and will remain a mainstay in migraine treatment.

Nearly all patients with migraine are recommended an acute medication to treat migraine attacks abortively; some patients are also recommended preventive therapies if migraine frequency significantly affects their quality of life. The American Headache Society/American Academy of Neurology guidelines for prevention recommend the initiation of a preventive medication at a frequency of 4-5 headache days per month or approximately 1 per week. Lipton and colleagues sought to determine whether there were any efficacy concerns in combining a CGRP mAb for prevention with ubrogepant, an oral CGRP antagonist, for acute treatment.

This was a prospective, open-level observational study assessing pain relief, return to normal function, and treatment satisfaction with patients given 50 or 100 mg of ubrogepant while concomitantly being given a seizure or mAb medication. Patients were allowed to be taking onabotulinumtoxinA as well as a CGRP mAb. The patients in this study were asked to track their headache symptoms using the Migraine Buddy e-diary. Meaningful pain relief was defined as a rating of migraine-related pain with one of the following choices 4 hours after taking the medication: no pain, mild pain, moderate pain, or severe pain. Return to normal function was defined as whether the patient determined they were able to function normally relative to their baseline at specific times post intervention. This was based on a functional disability scale. Treatment satisfaction was determined on the basis of a seven-point rating scale for how satisfied the patient felt with the medication at the end of the trial period.

A total of 245 participants provided at least 30 days of data, with 44.5% of the patients taking erenumab, 35.1% taking galcanezumab, 18.0% taking fremanezumab, and 2.9% taking eptinezumab. Meaningful pain relief was achieved by 61.6% of patients at 2 hours and 80.4% of patients at 4 hours post dose for both the 50-mg and 100-mg dose of ubrogepant. Return to normal function was achieved by 34.7% of patients at 2 hours and 50.5% at 4 hours post dose as well. Patients reported a 72.7% satisfaction level with the medication.

When CGRP acute medications were first approved, there was concern about the use of a mAb together with an oral antagonist. It was thought that CGRP medications would be associated with fewer benefits than when these medications were used alone, due to the belief that only a specific amount of CGRP could be blocked at any specific time. This trial shows that the efficacy of CGRP acute medications is not affected by concomitant use of mAb. Many patients who respond well to CGRP mAb will benefit significantly from the additional abortive use of oral antagonists.

The quadruplet combination of the anti-CD38 monoclonal antibody isatuximab with a backbone regimen of carfilzomib, lenalidomide and dexamethasone (IsaKRd) showed significant improvement in outcomes of measurable residual disease (MRD) in the treatment of newly diagnosed patients with multiple myeloma (MM).

“This [research] builds on our experience that four-drug combinations with a monoclonal antibody, proteasome inhibitor, immunomodulatory drug and steroids are superior to three-drug combinations,” Joseph Mikhael, MD, chief medical officer of the International Myeloma Foundation, said in an interview on the study.

“It also demonstrates the value of CD38 antibodies, and specifically isatuximab, in the frontline setting,” said Dr. Mikhael, professor at the Translational Genomics Research Institute (TGen), City of Hope Cancer Center in Goodyear, Ariz.

The findings were presented at the annual meeting of the American Society of Hematology.

The current standard of care for transplant-eligible, newly diagnosed MM consists of the quadruple combination of a CD38 monoclonal antibody, an immunomodulatory drug, a proteasome inhibitor, and a glucocorticoid, followed by high-dose melphalan and autologous stem-cell transplantation (ASCT).

Isatuximab already has approval in combination with the regimen of carfilzomib and dexamethasone (KRd) in the treatment of relapsed or refractory MM patients who have received prior lines of therapy.

To investigate the efficacy and safety of addition of isatuximab in the setting of transplant-eligible, newly diagnosed MM patients, first author Francesca Gay, MD, PhD, of the Division of Hematology, Department of Molecular Biotechnology and Health Sciences, University of Torino, Italy, and colleagues conducted the multisite, phase-3 Iskia trial, enrolling 302 transplant-eligible newly diagnosed MM patients.

The patients were randomized to groups of 151 each to treatment either with IsaKRd or KRd alone. The treatment regimen for KRd included four cycles in induction including weekly carfilzomib at 56 mg on day 1, 8 and 15, lenalidomide 25 mg at day 1-21, and dexamethasone at 40 mg weekly, and the IsaKRd group included four 28-day cycles of isatuximab 10 mg/kg IV days 1, 8, 15, and 22 in cycle 1, followed by 10 mg/kg days 1, 15 in cycles 2-4.

The induction was followed by stem cell mobilization and collection and high dose chemotherapy, followed by four cycles of full-dose consolidation at the same doses and schedule as induction, followed by a light consolidation phase of 12 28-day cycles of reduced dose KRd.

Patients had a median age of 61 and 60 in the isatuximab versus KRd group, respectively, and characteristics were similar between the two arms.

With the current follow-up of a mean of 21 months, the primary endpoint was met, with the intention-to-treat analysis showing a rate of post-consolidation MRD negativity, as assessed with a next-generation sequencing (NGS) cut-off of 10^-5, of 77% with isatuximab versus 67% with KRd alone (OR 1.67; P = .049).

With an NGS cut-off of 10^-6, the respective rates were 67% vs. 48% (OR 2.29; P < .001).

“This difference in MRD negativity in the depth of response was seen despite the responses analyzed according to the conventional criteria being comparable in the two arms, with more than 90% of patients achieving at least a very good partial response and more than 70% achieving at least a complete response,” Dr. Gay noted.

For the key secondary endpoint of MRD negativity over time, the rates were also significantly higher with IsaKRd vs. KRd at post-induction (10^-5 cut-off, 45% vs. 26%, OR 2.34; P < .001; 10^-6 cut-off, 27% vs. 14%, OR 2.36, P = .004).

IsaKRd also had greater MRD negativity post-ASCT (10^-5 cutoff 64% vs. 49%; P = .006; 10^-6 cutoff, 52% vs. 27%, P < .001) and post-consolidation (10^-5 cutoff, 77% vs. 67%; P = .049 and 10^-6 cutoff, 67% vs. 48%, P < .001).

The increase in the MRD negativity in the IsaKRd group was observed in all subgroups of patients analyzed at the 10^-5 and 10^-6 cut-offs.

The improved post-consolidation rate of MRD negativity with IsaKRd was also observed among patients based on all levels of cytogenetic risk, which was not the case in the KRd alone arm, which showed a reduction in MRD negativity among very high-risk patients, Dr. Gay observed.

The study’s other key secondary endpoint of progression-free survival will be presented in the future, when longer-term outcomes are available.

As of the current follow-up, 17% of patients in the IsaKRd group had discontinued the study treatment versus 10% with KRd, with the leading cause of adverse events for 6% and 5%, respectively.

At least one hematologic adverse event occurred in 55% of patients treated with IsaKRd and 44% in the KRd alone group, with the most prominent grade 3-4 adverse events occurring more commonly with IsaKRd being neutropenia (36% vs. 22%) and thrombocytopenia (15% vs. 17%).

Non-hematologic grade 3-4 adverse events occurred in 41% of patients in the IsaKRd group versus 37% in KRd only, which included infections (15% vs. 11%), and gastrointestinal (7% vs. 5%), vascular (5% vs. 10%) and cardiac events (<1% vs. 3%).

Discontinuation for toxicity occurred in similar rates in both groups (6% in IsaKRd vs. 5% in KRd); with four treatment-related deaths occurring with IsaKRd (two COVID, one pneumonia, one pulmonary embolism) and one with KRd (septic shock).

“Treatment was tolerable with a toxicity profile that was similar to that in previous reports,” Dr. Gay said.

“In the context of these highly effective regimens that produce a high rate of response, the 10-6 MRD cutoff might be more informative than other result categories,” she added.

Longer follow-up will provide more insights in survival endpoints, and “the trial can potentially offer the opportunity to explore correlations between depth of MRD negativity and survival endpoints,” Dr. Gay noted.

Further commenting on the study, Irene Ghobrial, MD, of Medical Oncology, with the Dana-Farber Cancer Institute, Boston, said the results are encouraging.

“We’re seeing two phase three trials now showing us that indeed a CD38 antibody in addition to our triplet standards of care are making a huge difference in MRD response,” she said in an interview.

“So, I think the main message here is that the four-drug regimen is the way to go from now on in multiple myeloma.”

The study received funding from Sanofi and Amgen. Dr. Gay disclosed relationships with AbbVie; Bristol Myers Squibb/Celgene; Sanofi; Roche; GlaxoSmithKline; Pfizer; Oncopeptides; Takeda; Janssen; and Amgen. Dr. Mikhael reported ties with Amgen, BMS, Janssen, Sanofi and Takeda.

Following the initial presentation, the lesion was initially considered an acquired port wine stain and the child was referred for laser treatment. Upon reassessment during laser treatment a few months later, the lesion had progressed to hyper- and hypopigmented plaques with associated tissue sclerosis and bone atrophy on the mid forehead, nose, and scalp. Patches of alopecia and atrophy were observed on the frontal scalp. The diagnosis was revised to linear morphea en coup de sabre and the child was referred to pediatric rheumatology and commenced treatment with methotrexate and oral corticosteroids.

Linear morphea, a rare connective tissue disorder, primarily affects girls in the first 2 decades of life. Lesions can initially present in many ways. Usually, they present as hypo- or hyperpigmented patches, but may also present as lichenoid uncolored or pink plaques resembling lichen striatus. There may also be erythematous patches mimicking a capillary malformation, as seen in our patient. A recent article reviewing the progression of the lesions from erythematous patches to sclerosis suggests it occurs between 3 and 7 months of age. Subsequent stages manifest as significant atrophy, hypo- and hyperpigmentation, and in severe cases, bone atrophy and deformity, often causing substantial cosmetic disfigurement and functional impairment.

Pathophysiologically, linear morphea involves a complex interplay of immunologic, vascular, and fibrotic processes. While the initial triggers remain elusive, dysregulated immune responses leading to endothelial injury, subsequent activation of fibroblasts and myofibroblasts, and excessive collagen deposition are implicated. Angiogenic disturbances exacerbate tissue ischemia, perpetuating the fibrotic cascade. Alterations in cytokine signaling pathways, particularly TGF-beta and interleukin-6, play pivotal roles in promoting fibrosis and modulating the inflammatory milieu.

Diagnosis of linear morphea en coup de sabre relies on clinical examination, imaging (ultrasonography, MRI, CT scan), and skin biopsy for histopathological analysis. Imaging helps evaluate tissue involvement, while histology reveals characteristic dermal sclerosis, collagen deposition, and inflammation. Early-stage histology may show telangiectatic changes, complicating its differentiation from capillary malformation.

Treatment aims to mitigate symptoms, halt disease progression, and improve cosmesis and functionality. This involves a multidisciplinary approach with systemic medications, phototherapy, physical therapy, and surgical interventions in severe cases. Early identification is crucial for systemic treatments such as methotrexate and systemic corticosteroids to arrest disease progression. Other adjunctive therapies include topical corticosteroids, calcineurin inhibitors, and phototherapy. Surgical procedures like tissue expansion or autologous fat grafting may address tissue atrophy and deformities.

Linear morphea en coup de sabre presents diagnostic and therapeutic challenges because of its rarity and variable clinical course. Collaborative efforts among dermatologists, rheumatologists, radiologists, and surgeons are essential for accurate diagnosis, evaluation, and tailored management. Continued research into pathogenesis and novel therapeutic agents is pivotal to enhance understanding and improve outcomes for those affected by this enigmatic dermatologic condition.

Early identification is crucial for systemic treatments such as methotrexate and systemic corticosteroids to arrest disease progression. Other adjunctive therapies include topical corticosteroids, calcineurin inhibitors, and phototherapy. Surgical procedures like tissue expansion or autologous fat grafting may address tissue atrophy and deformities.

Linear morphea en coup de sabre presents diagnostic and therapeutic challenges because of its rarity and variable clinical course. Collaborative efforts among dermatologists, rheumatologists, radiologists, and surgeons are essential for accurate diagnosis, evaluation, and tailored management. Continued research into pathogenesis and novel therapeutic agents is pivotal to enhance understanding and improve outcomes for those affected by this enigmatic dermatologic condition.

TOPLINE:

Women with fibromyalgia who received low-dose naltrexone showed no significant improvement in pain at 12 weeks, compared with those who received placebo in a randomized trial.

METHODOLOGY:

• The researchers randomly assigned 99 women with fibromyalgia at a single center in Denmark to a daily dose of 6 mg of naltrexone or a placebo for 12 weeks.
• The primary outcome was within-group change in pain intensity from baseline to 12 weeks, measured using an 11-point numeric rating scale (NRS) and the Fibromyalgia Impact Questionnaire-Revised (FIQR); outcomes were measured at 4, 8, and 12 weeks.
• Secondary outcomes included the global impact of FIQR total scores, as well as FIQR scores for tenderness, fatigue, , , anxiety, memory, stiffness, and physical function.

TAKEAWAY:

• The patients ranged in age from 18 to 64 years, with a mean age of 50.6 years, and all but one was White.
• At 12 weeks, the mean change in pain intensity was greater in the naltrexone group compared with the placebo group (−1.3 points vs −0.9 points, respectively), but the difference was not statistically significant.
• Of the secondary outcomes, only memory problems related to fibromyalgia showed significant improvement with naltrexone compared with placebo (−0.93 vs −0.30; P = .004), although the significance was lost after adjusting for multiplicity.
• Adverse events were infrequent and similar between the groups; four of 49 patients in the naltrexone group and three of 50 in the placebo group discontinued their assigned treatments because of side effects, and no safety concerns appeared related to the 6-mg dose.

IN PRACTICE:

“At this time we recommend that off-label treatment of patients who have responded to low-dose naltrexone should not be terminated, but we recommend against initiating low-dose naltrexone for low-dose naltrexone-naive patients with fibromyalgia pending the results of additional adequately powered studies with distinctive inflammatory and autoantibody patient profiles,” Winfried Häuser, MD, of the Center for Pain Medicine and Mental Health, Saarbrücken, Germany, and Mary-Ann Fitzcharles, MD, of McGill University Health Centre, Montreal, Canada, wrote in an accompanying editorial.

The lead author of the study was Karin Due Bruun, MD, of Odense University Hospital, Denmark. The full study and accompanying editorial were published online in The Lancet Rheumatology.

LIMITATIONS:

The study was only powered to detect a difference of 1.0 NRS points for pain intensity; other limitations include the homogenous population that prevents generalizability to other groups and the relatively short follow-up period.

DISCLOSURES:

The study was supported by the Danish Rheumatism Association, Odense University Hospital, Danielsen’s Foundation, and the Oak Foundation. The researchers had no financial conflicts to disclose.
