Ovarian cancer risk was higher in women with endometriosis overall and markedly increased in those with severe forms, a large population-based cohort study found.

The findings, published in JAMA, suggest these women may benefit from counseling on ovarian cancer risk and prevention and potentially from targeted screening, according to a group led by Mollie E. Barnard, ScD, of the Huntsman Cancer Institute at the University of Utah in Salt Lake City.

While the absolute increase in number of cases was small, endometriosis patients overall had a more than fourfold higher risk for any type of ovarian cancer. Those with more severe forms, such as ovarian endometriomas or deep infiltrating endometriosis, had a nearly 10-fold higher risk of any type of ovarian cancer. In addition, those with more severe endometriosis had a 19-fold higher risk of type 1 (slow-growing) ovarian cancer and almost three times the risk of the more aggressive type 2.

“Given the rarity of ovarian cancer, the excess risk was relatively small, with 10-20 additional cases per 10,000 women. Nevertheless, women with endometriosis, notably the more severe subtypes, may be an important population for targeted cancer screening and prevention studies,” said corresponding author Karen C. Schliep, PhD, MSPH, associate professor in the university’s Division of Public Health.

Prior studies have shown modest associations between endometriosis and ovarian cancer, Dr. Schliep said in an interview. A 2021 systematic review and meta-analysis found endometriosis conferred nearly double the risk of ovarian cancer, although associations varied by ovarian cancer histotype. Few studies have been large enough to assess associations between endometriosis types — including superficial or peritoneal endometriosis vs ovarian endometriomas or deep infiltrating endometriosis and ovarian cancer histotypes such as low-grade serous, endometrioid, clear cell, and mucinous carcinomas (type 1), and the most aggressive and lethal form, high-grade serous type 2, she said in an interview. “Our large health administrative database of over 11 million individuals with linked electronic health and cancer registry data allowed us to answer this as yet poorly studied research question.”
 

Study Details

Drawing on Utah electronic health records from 1992 to 2019, the investigators matched 78,893 women with endometriosis in a 1:5 ratio to unaffected women. Cases were categorized as superficial endometriosis, ovarian endometriomas, deep infiltrating endometriosis, or other, and the types of endometriosis were matched to ovarian cancer histotypes.

The mean age of patients at first endometriosis diagnosis was 36 and the mean follow-up was 12 years. Compared with controls, endometriosis patients were more likely to be nulliparous (31% vs 24%) and to have had a hysterectomy (39% vs 6%) during follow-up.

There were 596 reported cases of ovarian cancer in the cohort. Those with incident endometriosis were 4.2 times more likely to develop ovarian cancer (95% CI, 3.59-4.91), 7.48 times more likely to develop type 1 ovarian cancer (95% CI, 5.80-9.65), and 2.70 times more likely to develop type 2 ovarian cancer (95% CI, 2.09-3.49) compared with those without endometriosis.

The magnitudes of these associations varied by endometriosis subtype. Individuals diagnosed with deep infiltrating endometriosis and/or ovarian endometriomas had 9.66 times the risk of ovarian cancer vs individuals without endometriosis (95% CI, 7.77-12.00). “Women with, compared to without, more severe endometriosis had a 19-fold higher risk of type 1 ovarian cancer, including endometrioid, clear cell, mucinous, and low-grade serous,” Dr. Schliep said, with associated risk highest for malignant subtypes such as clear cell and endometrioid carcinoma (adjusted hazard ratios, 11.15 and 7.96, respectively.

According to Dr. Schliep, physicians should encourage endometriosis patients to be aware of but not worry about ovarian cancer risk because the likelihood of developing it remains low. For their part, patients can reduce their risk of cancer through a balanced diet with low intake of alcohol, regular exercise, a healthy weight, and abstention from smoking.

Her message for researchers is as follows: “We need more studies that explore how different types of endometriosis impact different types of ovarian cancer risk. These studies will guide improved ovarian cancer screening and prevention strategies among women with severe endometriosis, with or without other important ovarian cancer risk factors such as BRCA 1/2 variations.”

An accompanying editorial called the Utah study “eloquent” and noted its distinguishing contribution of observing associations between subtypes of endometriosis with overall risk for ovarian cancer as well as histologic subtypes of epithelial ovarian cancer.

Nevertheless, Michael T. McHale, MD, of the Department of Obstetrics, Gynecology, and Reproductive Sciences at Moores Cancer Center, UC San Diego Health, University of California, expressed some methodological concerns. Although the authors attempted to control for key confounders, he noted, the dataset could not provide details on the medical management of endometriosis, such as oral contraceptives or gonadotropin-releasing hormone agonists. “Additionally, there is a possibility that women in the control cohort could have had undiagnosed endometriosis,” he wrote.

Furthermore, making clinical recommendations from these reported observations, particularly with respect to deep infiltrating endometriosis, would require a clear and consistent definition of this type in the dataset over the entire study interval from 1992 to 2019 and for the state of Utah, which the authors did not provide.

“Despite this potential challenge, the increased risk associated with deep infiltrating and/or ovarian endometriosis was clearly significant,” Dr. McHale wrote.

And although the absolute number of ovarian cancers is limited, in his view, the increased risk is sufficiently significant to advise women who have completed childbearing or have alternative fertility options to consider “more definitive surgery.”

This study was supported by multiple not-for-profit agencies, including the National Cancer Institute, the University of Utah, the National Center for Research Resources, the Utah Department of Health and Human Services, the Utah Cancer Registry, the US Centers for Disease Control and Prevention, the Huntsman Cancer Foundation, the National Institutes of Health, and Doris Duke Foundation. Dr. Barnard reported grants from the National Cancer Institute during the conduct of the study and personal fees from Epi Excellence LLC outside the submitted work. Other coauthors reported similar funding from nonprofit agencies or private research organizations. Dr Schliep disclosed no competing interests. Dr McHale reported educational consulting for Eisai Training outside the submitted work.

Preconception and prenatal care are more complicated in women with chronic health conditions but attention to disease management and promoting the adoption of a healthier lifestyle can improve outcomes for mothers and infants, according to a growing body of research.

The latest version of the International Federation of Gynecology and Obstetrics Preconception Checklist, published in the International Journal of Gynecology & Obstetrics, highlights preexisting chronic medical conditions such as diabetes, lupus, and obesity as key factors to address in preconception care through disease management. A growing number of studies support the impact of these strategies on short- and long-term outcomes for mothers and babies, according to the authors.
 

Meet Glycemic Control Goals Prior to Pregnancy

“Women with diabetes can have healthy pregnancies but need to prepare for pregnancy in advance,” Ellen W. Seely, MD, professor of medicine at Harvard Medical School and director of clinical research in the endocrinology, diabetes, and hypertension division of Brigham and Women’s Hospital, Boston, said in an interview.

“If glucose levels are running high in the first trimester, this is associated with an increased risk of birth defects, some of which are very serious,” said Dr. Seely. Getting glucose levels under control reduces the risk of birth defects in women with diabetes close to that of the general population, she said.

The American Diabetes Association has set a goal for women to attain an HbA1c of less than 6.5% before conception, Dr. Seely said. “In addition, some women with diabetes may be on medications that should be changed to another class prior to pregnancy,” she noted. Women with type 1 or type 2 diabetes often have hypertension as well, but ACE inhibitors are associated with an increased risk of fetal renal damage that can result in neonatal death; therefore, these medications should be stopped prior to pregnancy, Dr. Seely emphasized.

“If a woman with type 2 diabetes is on medications other than insulin, recommendations from the ADA are to change to insulin prior to pregnancy, since we have the most data on the safety profile of insulin use in pregnancy,” she said.

To help women with diabetes improve glycemic control prior to pregnancy, Dr. Seely recommends home glucose monitoring, with checks of glucose four times a day, fasting, and 2 hours after each meal, and adjustment of insulin accordingly.

A healthy diet and physical activity remain important components of glycemic control as well. A barrier to proper preconception and prenatal care for women with diabetes is not knowing that a pregnancy should be planned, Dr. Seely said. Discussions about pregnancy should start at puberty for women with diabetes, according to the ADA, and the topic should be raised yearly so women can optimize their health and adjust medications prior to conception.

Although studies of drugs have been done to inform preconception care for women with diabetes, research is lacking in several areas, notably the safety of GLP-1 agonists in pregnancy, said Dr. Seely. “This class of drug is commonly used in type 2 diabetes and the current recommendation is to stop these agents 2 months prior to conception,” she said.
 

Conceive in Times of Lupus Remission

Advance planning also is important for a healthy pregnancy in women with systemic lupus erythematosus (SLE), Sayna Norouzi, MD, director of the glomerular disease clinic and polycystic kidney disease clinic of Loma Linda University Medical Center, California, said in an interview.

“Lupus mostly affects women of childbearing age and can create many challenges during pregnancy,” said Dr. Norouzi, the corresponding author of a recent review on managing lupus nephritis during pregnancy.

“Women with lupus face an increased risk of pregnancy complications such as preeclampsia, problems with fetal growth, stillbirth, and premature birth, and these risks increase based on factors such as disease activity, certain antibodies in the body, and other baseline existing conditions such as high blood pressure,” she said.

“It can be difficult to distinguish between a lupus flare and pregnancy-related issues, so proper management is important,” she noted. The Predictors of Pregnancy Outcome: Biomarkers in Antiphospholipid Syndrome and Systemic Lupus Erythematosus (PROMISSE) study findings indicated a lupus nephritis relapse rate of 7.8% of patients in complete remission and 21% of those in partial remission during pregnancy, said Dr. Norouzi. “Current evidence has shown that SLE patients without lupus nephritis flare in the preconception period have a small risk of relapse during pregnancy,” she said.

Before and during pregnancy, women with lupus should work with their treating physicians to adjust medications for safety, watch for signs of flare, and aim to conceive during a period of lupus remission.

Preconception care for women with lupus nephritis involves a careful review of the medications used to control the disease and protect the kidneys and other organs, said Dr. Norouzi.

“Adjustments,” she said, “should be personalized, taking into account the mother’s health and the safety of the baby. Managing the disease actively during pregnancy may require changes to the treatment plan while minimizing risks,” she noted. However, changing medications can cause challenges for patients, as medications that are safer for pregnancy may lead to new symptoms and side effects, and patients will need to work closely with their healthcare providers to overcome new issues that arise, she added.

Preconception lifestyle changes such as increasing exercise and adopting a healthier diet can help with blood pressure control for kidney disease patients, said Dr. Norouzi.

In the review article, Dr. Norouzi and colleagues noted that preconception counseling for patients with lupus should address common comorbidities such as hypertension, diabetes, obesity, and dyslipidemia, and the risk for immediate and long-term cardiovascular complications.
 

Benefits of Preconception Obesity Care Extend to Infants

Current guidelines from the American College of Obstetricians and Gynecologists and the Institute of Medicine advise lifestyle interventions to reduce excessive weight gain during pregnancy and reduce the risk of inflammation, oxidative stress, insulin resistance, and lipotoxicity that can promote complications in the mother and fetus during pregnancy.

In addition, a growing number of studies suggest that women with obesity who make healthy lifestyle changes prior to conception can reduce obesity-associated risks to their infants.

Adults born to women with obesity are at increased risk of cardiovascular disease and early signs of heart remodeling are identifiable in newborns, Samuel J. Burden, PhD, a research associate in the department of women and children’s health, Kings’ College, London, said in an interview. “It is therefore important to investigate whether intervening either before or during pregnancy by promoting a healthy lifestyle can reduce this adverse impact on the heart and blood vessels,” he said.

In a recent study published in the International Journal of Obesity, Dr. Burden and colleagues examined data from eight studies based on data from five randomized, controlled trials including children of mothers with obesity who engaged in healthy lifestyle interventions of improved diet and increased physical activity prior to and during pregnancy. The study population included children ranging in age from less than 2 months to 3-7 years.

Lifestyle interventions for mothers both before conception and during pregnancy were associated with significant changes in cardiac remodeling in the children, notably reduced interventricular septal wall thickness. Additionally, five studies of cardiac systolic function and three studies of diastolic function showed improvement in blood pressure in children of mothers who took part in the interventions.

Dr. Burden acknowledged that lifestyle changes in women with obesity before conception and during pregnancy can be challenging, but should be encouraged. “During pregnancy, it may also seem unnatural to increase daily physical activity or change the way you are eating.” He emphasized that patients should consult their physicians and follow an established program. More randomized, controlled trials are needed from the preconception period to examine whether the health benefits are greater if the intervention begins prior to pregnancy, said Dr. Burden. However, “the current findings indeed indicate that women with obesity who lead a healthy lifestyle before and during their pregnancy can reduce the degree of unhealthy heart remodeling in their children,” he said.

Dr. Seely, Dr. Norouzi, and Dr. Burden had no financial conflicts to disclose.

The American Diabetes Association has set a goal for women to attain an HbA1c of less than 6.5% before conception, Dr. Seely said. “In addition, some women with diabetes may be on medications that should be changed to another class prior to pregnancy,” she noted. Women with type 1 or type 2 diabetes often have hypertension as well, but ACE inhibitors are associated with an increased risk of fetal renal damage that can result in neonatal death; therefore, these medications should be stopped prior to pregnancy, Dr. Seely emphasized.

“If a woman with type 2 diabetes is on medications other than insulin, recommendations from the ADA are to change to insulin prior to pregnancy, since we have the most data on the safety profile of insulin use in pregnancy,” she said.

To help women with diabetes improve glycemic control prior to pregnancy, Dr. Seely recommends home glucose monitoring, with checks of glucose four times a day, fasting, and 2 hours after each meal, and adjustment of insulin accordingly.

A healthy diet and physical activity remain important components of glycemic control as well. A barrier to proper preconception and prenatal care for women with diabetes is not knowing that a pregnancy should be planned, Dr. Seely said. Discussions about pregnancy should start at puberty for women with diabetes, according to the ADA, and the topic should be raised yearly so women can optimize their health and adjust medications prior to conception.

Although studies of drugs have been done to inform preconception care for women with diabetes, research is lacking in several areas, notably the safety of GLP-1 agonists in pregnancy, said Dr. Seely. “This class of drug is commonly used in type 2 diabetes and the current recommendation is to stop these agents 2 months prior to conception,” she said.
 

Conceive in Times of Lupus Remission

Advance planning also is important for a healthy pregnancy in women with systemic lupus erythematosus (SLE), Sayna Norouzi, MD, director of the glomerular disease clinic and polycystic kidney disease clinic of Loma Linda University Medical Center, California, said in an interview.

“Lupus mostly affects women of childbearing age and can create many challenges during pregnancy,” said Dr. Norouzi, the corresponding author of a recent review on managing lupus nephritis during pregnancy.

“Women with lupus face an increased risk of pregnancy complications such as preeclampsia, problems with fetal growth, stillbirth, and premature birth, and these risks increase based on factors such as disease activity, certain antibodies in the body, and other baseline existing conditions such as high blood pressure,” she said.

“It can be difficult to distinguish between a lupus flare and pregnancy-related issues, so proper management is important,” she noted. The Predictors of Pregnancy Outcome: Biomarkers in Antiphospholipid Syndrome and Systemic Lupus Erythematosus (PROMISSE) study findings indicated a lupus nephritis relapse rate of 7.8% of patients in complete remission and 21% of those in partial remission during pregnancy, said Dr. Norouzi. “Current evidence has shown that SLE patients without lupus nephritis flare in the preconception period have a small risk of relapse during pregnancy,” she said.

Before and during pregnancy, women with lupus should work with their treating physicians to adjust medications for safety, watch for signs of flare, and aim to conceive during a period of lupus remission.

Preconception care for women with lupus nephritis involves a careful review of the medications used to control the disease and protect the kidneys and other organs, said Dr. Norouzi.

“Adjustments,” she said, “should be personalized, taking into account the mother’s health and the safety of the baby. Managing the disease actively during pregnancy may require changes to the treatment plan while minimizing risks,” she noted. However, changing medications can cause challenges for patients, as medications that are safer for pregnancy may lead to new symptoms and side effects, and patients will need to work closely with their healthcare providers to overcome new issues that arise, she added.

Preconception lifestyle changes such as increasing exercise and adopting a healthier diet can help with blood pressure control for kidney disease patients, said Dr. Norouzi.

In the review article, Dr. Norouzi and colleagues noted that preconception counseling for patients with lupus should address common comorbidities such as hypertension, diabetes, obesity, and dyslipidemia, and the risk for immediate and long-term cardiovascular complications.
 

Benefits of Preconception Obesity Care Extend to Infants

Current guidelines from the American College of Obstetricians and Gynecologists and the Institute of Medicine advise lifestyle interventions to reduce excessive weight gain during pregnancy and reduce the risk of inflammation, oxidative stress, insulin resistance, and lipotoxicity that can promote complications in the mother and fetus during pregnancy.

In addition, a growing number of studies suggest that women with obesity who make healthy lifestyle changes prior to conception can reduce obesity-associated risks to their infants.

Adults born to women with obesity are at increased risk of cardiovascular disease and early signs of heart remodeling are identifiable in newborns, Samuel J. Burden, PhD, a research associate in the department of women and children’s health, Kings’ College, London, said in an interview. “It is therefore important to investigate whether intervening either before or during pregnancy by promoting a healthy lifestyle can reduce this adverse impact on the heart and blood vessels,” he said.

In a recent study published in the International Journal of Obesity, Dr. Burden and colleagues examined data from eight studies based on data from five randomized, controlled trials including children of mothers with obesity who engaged in healthy lifestyle interventions of improved diet and increased physical activity prior to and during pregnancy. The study population included children ranging in age from less than 2 months to 3-7 years.

Lifestyle interventions for mothers both before conception and during pregnancy were associated with significant changes in cardiac remodeling in the children, notably reduced interventricular septal wall thickness. Additionally, five studies of cardiac systolic function and three studies of diastolic function showed improvement in blood pressure in children of mothers who took part in the interventions.

Dr. Burden acknowledged that lifestyle changes in women with obesity before conception and during pregnancy can be challenging, but should be encouraged. “During pregnancy, it may also seem unnatural to increase daily physical activity or change the way you are eating.” He emphasized that patients should consult their physicians and follow an established program. More randomized, controlled trials are needed from the preconception period to examine whether the health benefits are greater if the intervention begins prior to pregnancy, said Dr. Burden. However, “the current findings indeed indicate that women with obesity who lead a healthy lifestyle before and during their pregnancy can reduce the degree of unhealthy heart remodeling in their children,” he said.

Dr. Seely, Dr. Norouzi, and Dr. Burden had no financial conflicts to disclose.

Most women (72%) are not aware they are at risk for developing uterine fibroids, though up to 77% of women will develop them in their lifetime, results of a new survey indicate.

Data from The Harris Poll, conducted on behalf of the Society of Interventional Radiology, also found that 17% of women mistakenly think a hysterectomy is the only treatment option, including more than one in four women (27%) who are between the ages of 18 and 34. Results were shared in a press release. The survey included 1,122 US women, some who have been diagnosed with uterine fibroids.

Fibroids may not cause symptoms for some, but some women may have heavy, prolonged, debilitating bleeding. Some women experience pelvic pain, a diminished sex life, and declining energy. However, the growths do not spread to other body regions and typically are not dangerous.
 

Hysterectomy Is Only One Option

Among the women in the survey who had been diagnosed with fibroids, 53% were presented the option of hysterectomy and 20% were told about other, less-invasive options, including over-the-counter NSAIDs (19%); uterine fibroid embolization (UFE) (17%); oral contraceptives (17%); and endometrial ablation (17%).

“Women need to be informed about the complete range of options available for treating their uterine fibroids, not just the surgical options as is most commonly done by gynecologists,” John C. Lipman, MD, founder and medical director of the Atlanta Fibroid Center in Smyrna, Georgia, said in the press release.

The survey also found that:

• More than half of women ages 18-34 (56%) and women ages 35-44 (51%) were either not familiar with uterine fibroids or never heard of them.
• Awareness was particularly low among Hispanic women, as 50% of Hispanic women say they’ve never heard of or aren’t familiar with the condition, compared with 37% of Black women who answered that way.
• More than one third (36%) of Black women and 22% of Hispanic women mistakenly think they are not at risk for developing fibroids, yet research has shown that uterine fibroids are three times more common in Black women and two times more common in Hispanic women than in White women.

For this study, the full sample data is accurate to within +/– 3.2 percentage points using a 95% confidence level. The data are part of the report “The Fibroid Fix: What Women Need to Know,” published on July 9 by the Society of Interventional Radiology.

Linda Fan, MD, chief of gynecology at Yale University in New Haven, Connecticut, said she is not surprised by those numbers. She says many patients are referred to her department who have not been given the full array of medical options for their fibroids or have not had thorough discussions with their providers, such as whether they want to preserve their fertility, or how they feel about an incision, undergoing anesthesia, or having their uterus removed.

Sometimes the hysterectomy choice is clear, she said — for instance, if there are indications of the rare cancer leiomyosarcoma, or if a postmenopausal woman has rapid growth of fibroids or heavy bleeding. Fibroids should not start growing after menopause, she said.

Additional options include radiofrequency ablation, performed while a patient is under anesthesia, by laparoscopy or hysteroscopy. The procedure uses ultrasound to watch a probe as it shrinks the fibroids with heat.

Currently, if a woman wants large fibroids removed and wants to keep her fertility options open, Dr. Fan says, myomectomy or medication are best “because we have the most information or data on (those options).”

When treating patients who don’t prioritize fertility, she said, UFE is a good option that doesn’t need incisions or anesthesia. But patients sometimes require a lot of pain medication afterward, Dr. Fan said. With radiofrequency ablation, specifically the Acessa and Sonata procedures, she said, “patients don’t experience a lot of pain after the procedure because the shrinking happens when they’re asleep under anesthesia.”
 

Uterine Fibroid Embolization a Nonsurgical Option

The report describes how UFE works but the Harris Poll showed that 60% of women who have heard of UFE did not hear about it first from a healthcare provider.

“UFE is a nonsurgical treatment, performed by interventional radiologists, that has been proven to significantly reduce heavy menstrual bleeding, relieve uterine pain, and improve energy levels,” the authors write. “Through a tiny incision in the wrist or thigh, a catheter is guided via imaging to the vessels leading to the fibroids. Through this catheter, small clear particles are injected to block the blood flow leading to the fibroids causing them to shrink and disappear.”

After UFE, most women leave the hospital the day of or the day after treatment, according to the report authors, who add that many patients also report they can resume normal activity in about 2 weeks, more quickly than with surgical treatments.

In some cases, watchful waiting will be the best option, the report notes, and that may require repeated checkups and scans.

Introduction: Tremendous Progress on Cancer Extends to Cancer in Pregnancy

The biomedical research enterprise that took shape in the United States after World War II has had numerous positive effects, including significant progress made during the past 75-plus years in the diagnosis, prevention, and treatment of cancer.

President Franklin D. Roosevelt’s 1944 request of Dr. Vannevar Bush, director of the then Office of Scientific Research and Development, to organize a program that would advance and apply scientific knowledge for times of peace — just as it been advanced and applied in times of war — culminated in a historic report, Science – The Endless Frontier. Presented in 1945 to President Harry S. Truman, this report helped fuel decades of broad, bold, and coordinated government-sponsored biomedical research aimed at addressing disease and improving the health of the American people (National Science Foundation, 1945).

Discoveries made from research in basic and translational sciences deepened our knowledge of the cellular and molecular underpinnings of cancer, leading to advances in chemotherapy, radiotherapy, and other treatment approaches as well as continual refinements in their application. Similarly, our diagnostic armamentarium has significantly improved.

Albert Reece, MD, PhD, MBA, a maternal-fetal medicine specialist, is dean emeritus of the University of Maryland School of Medicine, former university executive vice president; currently the endowed professor and director of the Center for Advanced Research Training and Innovation (CARTI), and senior scientist in the Center for Birth Defects Research. Dr. Reece reported no relevant disclosures. He is the medical editor of this column. Contact him at [email protected].

Managing Cancer in Pregnancy

Cancer can cause fear and distress for any patient, but when cancer is diagnosed during pregnancy, an expectant mother fears not only for her own health but for the health of her unborn child. Fortunately, ob.gyn.s and multidisciplinary teams have good reason to reassure patients about the likelihood of good outcomes.

Cancer treatment in pregnancy has improved with advancements in imaging and chemotherapy, and while maternal and fetal outcomes of prenatal cancer treatment are not well reported, evidence acquired in recent years from case series and retrospective studies shows that most imaging studies and procedural diagnostic tests – and many treatments – can be performed safely in pregnancy.

Cancer Incidence, Use of Diagnostic Imaging

Data on the incidence of cancer in pregnancy comes from population-based cancer registries, and unfortunately, these data are not standardized and are often incomplete. Many studies include cancer diagnosed up to 1 year after pregnancy, and some include preinvasive disease. Estimates therefore vary considerably (see Table 1 for a sampling of estimates incidences.)

It has been reported, and often cited in the literature, that invasive malignancy complicates one in 1,000 pregnancies and that the incidence of cancer in pregnancy (invasive and noninvasive malignancies) has been rising over time.⁸ Increasing maternal age is believed to be playing a role in this rise; as women delay childbearing, they enter the age range in which some cancers become more common. Additionally, improvements in screening and diagnostics have led to earlier cancer detection. The incidence of ovarian neoplasms found during pregnancy has increased, for instance, with the routine use of diagnostic ultrasound in pregnancy.¹

Among the studies showing an increased incidence of pregnancy-associated cancer is a population-based study in Australia, which found that from 1994 to 2007 the crude incidence of pregnancy-associated cancer increased from 112.3 to 191.5 per 100,000 pregnancies (P < .001).⁹ A cohort study in the United States documented an increase in incidence from 75.0 per 100,000 pregnancies in 2002 to 138.5 per 100,000 pregnancies in 2012.¹⁰

Overall, the literature shows us that the skin, cervix, and breast are also common sites for malignancy during pregnancy.¹ According to a 2022 review, breast cancer during pregnancy is less often hormone receptor–positive and more frequently triple negative compared with age-matched controls.¹¹ The frequencies of other pregnancy-associated cancers appear overall to be similar to that of cancer occurring in all women across their reproductive years.¹

Too often, diagnosis is delayed because cancer symptoms can be masked by or can mimic normal physiological changes in pregnancy. For instance, breast cancer can be difficult to diagnose during pregnancy and lactation due to anatomic changes in the breast parenchyma. Several studies published in the 1990s showed that breast cancer presents at a more advanced stage in pregnant patients than in nonpregnant patients because of this delay.¹ Skin changes suggestive of melanoma can be attributed to hyperpigmentation of pregnancy, for instance. Several observational studies have suggested that thicker melanomas found in pregnancy may be because of delayed diagnosis.⁸

It is important that we thoroughly investigate signs and symptoms suggestive of a malignancy and not automatically attribute these symptoms to the pregnancy itself. Cervical biopsy of a mass or lesion suspicious for cervical cancer can be done safely during pregnancy and should not be delayed or deferred.

Fetal radiation exposure from radiologic examinations has long been a concern, but we know today that while the imaging modality should be chosen to minimize fetal radiation exposure, CT scans and even PET scans should be performed if these exams are deemed best for evaluation. Embryonic exposure to a dose of less than 50 mGy is rarely if at all associated with fetal malformations or miscarriage and a radiation dose of 100 mGy may be considered a floor for consideration of therapeutic termination of pregnancy.^1,8

CT exams are associated with a fetal dose far less than 50 mGy (see Table 2 for radiation doses).

Chemotherapy, Surgery, and Radiation in Pregnancy

The management of cancer during pregnancy requires a multidisciplinary team including medical, gynecologic, or radiation oncologists, and maternal-fetal medicine specialists (Figure 1). Prematurity and low birth weight are frequent complications for fetuses exposed to chemotherapy, although there is some uncertainty as to whether the treatment is causative. However, congenital anomalies no longer are a major concern, provided that drugs are appropriately selected and that fetal exposure occurs during the second or third trimester.

For instance, alkylating agents including cisplatin (an important drug in the management of gynecologic malignancies) have been associated with congenital anomalies in the first trimester but not in the second and third trimesters, and a variety of antimetabolites — excluding methotrexate and aminopterin — similarly have been shown to be relatively safe when used after the first trimester.¹

Small studies have shown no long-term effects of chemotherapy exposure on postnatal growth and long-term neurologic/neurocognitive function,¹ but this is an area that needs more research.

Also in need of investigation is the safety of newer agents in pregnancy. Data are limited on the use of new targeted treatments, monoclonal antibodies, and immunotherapies in pregnancy and their effects on the fetus, with current knowledge coming mainly from single case reports.¹³

Until more is learned — a challenge given that pregnant women are generally excluded from clinical trials — management teams are generally postponing use of these therapies until after delivery. Considering the pace of new developments revolutionizing cancer treatment, this topic will likely get more complex and confusing before we begin acquiring sufficient knowledge.

The timing of surgery for malignancy in pregnancy is similarly based on the balance of maternal and fetal risks, including the risk of maternal disease progression, the risk of preterm delivery, and the prevention of fetal metastases. In general, the safest time is the second trimester.

Maternal surgery in the third trimester may be associated with a risk of premature labor and altered uteroplacental perfusion. A 2005 systematic review of 12,452 women who underwent nonobstetric surgery during pregnancy provides some reassurance, however; compared with the general obstetric population, there was no increase in the rate of miscarriage or major birth defects.¹⁴

Radiotherapy used to be contraindicated in pregnancy but many experts today believe it can be safely utilized provided the uterus is out of field and is protected from scattered radiation. The head, neck, and breast, for instance, can be treated with newer radiotherapies, including stereotactic ablative radiation therapy.⁸ Patients with advanced cervical cancer often receive chemotherapy during pregnancy to slow metastatic growth followed by definitive treatment with postpartum radiation or surgery.

More research is needed, but available data on maternal outcomes are encouraging. For instance, there appear to be no significant differences in short- and long-term complications or survival between women who are pregnant and nonpregnant when treated for invasive cervical cancer.⁸ Similarly, while earlier studies of breast cancer diagnosed during pregnancy suggested a poor prognosis, data now show similar prognoses for pregnant and nonpregnant patients when controlled for stage.¹

It has been reported, and often cited in the literature, that invasive malignancy complicates one in 1,000 pregnancies and that the incidence of cancer in pregnancy (invasive and noninvasive malignancies) has been rising over time.⁸ Increasing maternal age is believed to be playing a role in this rise; as women delay childbearing, they enter the age range in which some cancers become more common. Additionally, improvements in screening and diagnostics have led to earlier cancer detection. The incidence of ovarian neoplasms found during pregnancy has increased, for instance, with the routine use of diagnostic ultrasound in pregnancy.¹

Among the studies showing an increased incidence of pregnancy-associated cancer is a population-based study in Australia, which found that from 1994 to 2007 the crude incidence of pregnancy-associated cancer increased from 112.3 to 191.5 per 100,000 pregnancies (P < .001).⁹ A cohort study in the United States documented an increase in incidence from 75.0 per 100,000 pregnancies in 2002 to 138.5 per 100,000 pregnancies in 2012.¹⁰

Overall, the literature shows us that the skin, cervix, and breast are also common sites for malignancy during pregnancy.¹ According to a 2022 review, breast cancer during pregnancy is less often hormone receptor–positive and more frequently triple negative compared with age-matched controls.¹¹ The frequencies of other pregnancy-associated cancers appear overall to be similar to that of cancer occurring in all women across their reproductive years.¹

Too often, diagnosis is delayed because cancer symptoms can be masked by or can mimic normal physiological changes in pregnancy. For instance, breast cancer can be difficult to diagnose during pregnancy and lactation due to anatomic changes in the breast parenchyma. Several studies published in the 1990s showed that breast cancer presents at a more advanced stage in pregnant patients than in nonpregnant patients because of this delay.¹ Skin changes suggestive of melanoma can be attributed to hyperpigmentation of pregnancy, for instance. Several observational studies have suggested that thicker melanomas found in pregnancy may be because of delayed diagnosis.⁸

It is important that we thoroughly investigate signs and symptoms suggestive of a malignancy and not automatically attribute these symptoms to the pregnancy itself. Cervical biopsy of a mass or lesion suspicious for cervical cancer can be done safely during pregnancy and should not be delayed or deferred.

Fetal radiation exposure from radiologic examinations has long been a concern, but we know today that while the imaging modality should be chosen to minimize fetal radiation exposure, CT scans and even PET scans should be performed if these exams are deemed best for evaluation. Embryonic exposure to a dose of less than 50 mGy is rarely if at all associated with fetal malformations or miscarriage and a radiation dose of 100 mGy may be considered a floor for consideration of therapeutic termination of pregnancy.^1,8

CT exams are associated with a fetal dose far less than 50 mGy (see Table 2 for radiation doses).

Chemotherapy, Surgery, and Radiation in Pregnancy

The management of cancer during pregnancy requires a multidisciplinary team including medical, gynecologic, or radiation oncologists, and maternal-fetal medicine specialists (Figure 1). Prematurity and low birth weight are frequent complications for fetuses exposed to chemotherapy, although there is some uncertainty as to whether the treatment is causative. However, congenital anomalies no longer are a major concern, provided that drugs are appropriately selected and that fetal exposure occurs during the second or third trimester.

For instance, alkylating agents including cisplatin (an important drug in the management of gynecologic malignancies) have been associated with congenital anomalies in the first trimester but not in the second and third trimesters, and a variety of antimetabolites — excluding methotrexate and aminopterin — similarly have been shown to be relatively safe when used after the first trimester.¹

Small studies have shown no long-term effects of chemotherapy exposure on postnatal growth and long-term neurologic/neurocognitive function,¹ but this is an area that needs more research.

Also in need of investigation is the safety of newer agents in pregnancy. Data are limited on the use of new targeted treatments, monoclonal antibodies, and immunotherapies in pregnancy and their effects on the fetus, with current knowledge coming mainly from single case reports.¹³

Until more is learned — a challenge given that pregnant women are generally excluded from clinical trials — management teams are generally postponing use of these therapies until after delivery. Considering the pace of new developments revolutionizing cancer treatment, this topic will likely get more complex and confusing before we begin acquiring sufficient knowledge.

The timing of surgery for malignancy in pregnancy is similarly based on the balance of maternal and fetal risks, including the risk of maternal disease progression, the risk of preterm delivery, and the prevention of fetal metastases. In general, the safest time is the second trimester.

Maternal surgery in the third trimester may be associated with a risk of premature labor and altered uteroplacental perfusion. A 2005 systematic review of 12,452 women who underwent nonobstetric surgery during pregnancy provides some reassurance, however; compared with the general obstetric population, there was no increase in the rate of miscarriage or major birth defects.¹⁴

Radiotherapy used to be contraindicated in pregnancy but many experts today believe it can be safely utilized provided the uterus is out of field and is protected from scattered radiation. The head, neck, and breast, for instance, can be treated with newer radiotherapies, including stereotactic ablative radiation therapy.⁸ Patients with advanced cervical cancer often receive chemotherapy during pregnancy to slow metastatic growth followed by definitive treatment with postpartum radiation or surgery.

More research is needed, but available data on maternal outcomes are encouraging. For instance, there appear to be no significant differences in short- and long-term complications or survival between women who are pregnant and nonpregnant when treated for invasive cervical cancer.⁸ Similarly, while earlier studies of breast cancer diagnosed during pregnancy suggested a poor prognosis, data now show similar prognoses for pregnant and nonpregnant patients when controlled for stage.¹

Introduction: Tremendous Progress on Cancer Extends to Cancer in Pregnancy

The biomedical research enterprise that took shape in the United States after World War II has had numerous positive effects, including significant progress made during the past 75-plus years in the diagnosis, prevention, and treatment of cancer.

President Franklin D. Roosevelt’s 1944 request of Dr. Vannevar Bush, director of the then Office of Scientific Research and Development, to organize a program that would advance and apply scientific knowledge for times of peace — just as it been advanced and applied in times of war — culminated in a historic report, Science – The Endless Frontier. Presented in 1945 to President Harry S. Truman, this report helped fuel decades of broad, bold, and coordinated government-sponsored biomedical research aimed at addressing disease and improving the health of the American people (National Science Foundation, 1945).

Discoveries made from research in basic and translational sciences deepened our knowledge of the cellular and molecular underpinnings of cancer, leading to advances in chemotherapy, radiotherapy, and other treatment approaches as well as continual refinements in their application. Similarly, our diagnostic armamentarium has significantly improved.

Managing Cancer in Pregnancy

Cancer can cause fear and distress for any patient, but when cancer is diagnosed during pregnancy, an expectant mother fears not only for her own health but for the health of her unborn child. Fortunately, ob.gyn.s and multidisciplinary teams have good reason to reassure patients about the likelihood of good outcomes.

Cancer treatment in pregnancy has improved with advancements in imaging and chemotherapy, and while maternal and fetal outcomes of prenatal cancer treatment are not well reported, evidence acquired in recent years from case series and retrospective studies shows that most imaging studies and procedural diagnostic tests – and many treatments – can be performed safely in pregnancy.

Cancer Incidence, Use of Diagnostic Imaging

Data on the incidence of cancer in pregnancy comes from population-based cancer registries, and unfortunately, these data are not standardized and are often incomplete. Many studies include cancer diagnosed up to 1 year after pregnancy, and some include preinvasive disease. Estimates therefore vary considerably (see Table 1 for a sampling of estimates incidences.)

Rachel S. Rubin, MD: Hi, everybody. Welcome back to another episode of Sex Matters. I am Dr Rachel Rubin. I’m a urologist and sexual medicine specialist in the Washington, DC, area, and I am thrilled to bring you this next guest. This is someone I am a huge fan of. I have been following her research for decades now, and we are so blessed to have her: Debby Herbenick. Why don’t you introduce yourself and tell people all about your research?

Debby Herbenick, PhD: I’m a professor at the Indiana University School of Public Health, and I’ve been a sexuality researcher and educator for about 25 years. I’ve studied issues related to women’s orgasm, vibrator use, how people feel about their genitals, and how that impacts whether or not they are comfortable seeking healthcare. Most recently, I’ve been looking at emerging sexual practices.

Dr. Rubin: You can’t be in sexual medicine without knowing Dr. Herbenick’s work. It is just instrumental to our knowledge about what people are actually doing, what people care about, and what’s happening out there. Probably not a day goes by that I don’t quote your research on how women experience sexual pleasure, how women orgasm. Can you talk briefly about that research?

Dr. Herbenick: I’ve done a lot of research related to pleasure and orgasm, some related to the different styles of touch, some related to vibrator use, showing that more than half of women reported having ever used a vibrator. The key is really variety. People need to feel comfortable with the way that they experience their bodies and their own paths to pleasure, and feel supported in being able to explore in that way.

Dr. Rubin: And what are some resources? What I often quote is that everyone thinks, because of Hollywood and pornography, that women orgasm from vaginal penetration alone, which of course we know physiologically doesn’t make sense. The numbers are staggering. People often go to their doctor and say: “I’m not normal. I can’t orgasm from penetration. Is there something wrong with me?”

Dr. Herbenick: Most women are not orgasming from vaginal intercourse alone. Many have added direct clitoral stimulation. Others prefer to receive oral sex. Some are having orgasms with a vibrator or other kinds of sex toys. And for some, it’s not just the behavior, right? It’s having the behavior in a certain amount of intimacy or connection with a partner, so really focusing on that as well.

Dr. Rubin: Your data show that more than 50% of women have used vibration in the past. I tell my male patients as well that the penis and the clitoris are the same. The penis likes vibration too, but many have never tried it. As a clinician, being able to encourage patients to use these devices and tools is really important. Your data help us show that this is an important aspect of pleasure.

Dr. Herbenick: I’m always glad to hear they’re helpful. And, of course, our research really focused on vibrators, but it’s been so interesting to see the sexual enhancement products change over the years. And now we have all these air pressure toys, too, which are especially useful for people who really can’t take or don’t prefer direct contact with their clitoris or other genital parts.

Dr. Rubin: I tell my patients all the time that the sex devices that we use today are not the same things from back in the day. There are so many high technological advances in this space that are really wonderful tools for me as a doctor, that I can really help my patients understand and use just to have more fun.

Dr. Herbenick: Absolutely.

Dr. Rubin: Very few of us are sexual medicine–trained physicians who feel confident and comfortable talking about sexual health issues. How can they find you or follow you?

Dr. Herbenick: I’m on social media as Debby Herbenick. I’m also on our website at Indiana University, the Center for Sexual Health Promotion.

Dr. Rubin: Thank you so much for joining us today.

TOPLINE:

Combat exposure is strongly associated with chronic pain in active-duty servicewomen and female civilian dependents of military personnel on active duty; a lower socioeconomic status and mental health conditions further increased the likelihood of chronic pain.

METHODOLOGY:

• Researchers analyzed claims data from the Military Health System to identify chronic pain diagnoses among active-duty servicewomen and civilian dependents of individuals on active duty.
• A total of 3,473,401 individuals (median age, 29 years) were included in the study, with 644,478 active-duty servicewomen and 2,828,923 civilian dependents.
• The study compared the incidence of chronic pain during 2006-2013, a period of heightened deployment intensity, with 2014-2020, a period of reduced deployment intensity.
• The primary outcome was the diagnosis of chronic pain.

TAKEAWAY:

• Active-duty servicewomen in the years 2006-2013 had a 53% increase in the odds of reporting chronic pain compared with those in the period between 2014 and 2020 (odds ratio [OR], 1.53; 95% CI, 1.48-1.58).
• Civilian dependents in the years 2006-2013 had a 96% increase in the odds of chronic pain compared with those in the later interval (OR, 1.96; 95% CI, 1.93-1.99).
• In 2006-2013, junior enlisted active-duty servicewomen had nearly a twofold increase in the odds of chronic pain (OR, 1.95; 95% CI, 1.83-2.09), while junior enlisted dependents had more than a threefold increase in the odds of chronic pain (OR, 3.05; 95% CI, 2.87-3.25) compared with senior officers.
• Comorbid mental conditions also were associated with an increased odds of reporting chronic pain (OR, 1.67; 95% CI, 1.65-1.69).

IN PRACTICE:

“The potential for higher rates of chronic pain in women veterans has been theorized to result from differences in support structures, family conflict, coping strategies, stress regulation, and exposure to military sexual trauma,” the authors wrote. “Our results suggest that these contributing factors may carry over to the women dependents of combat veterans in addition, indicating a line of research that requires urgent further exploration.”

The study was led by Andrew J. Schoenfeld, MD, MSc, of the Center for Surgery and Public Health, Department of Orthopaedic Surgery at Brigham and Women’s Hospital and Harvard Medical School, in Boston. It was published online on July 5, 2024, in JAMA Network Open.

LIMITATIONS:

This study relied on claims-based data, which may have issues with coding accuracy and limited clinical granularity. The population size reduced over time owing to military downsizing, which could impact the findings. The prevalence of chronic pain in the population was likely underestimated because individuals who did not report symptoms or were diagnosed after separation from service were not identified.

TOPLINE:

Combat exposure is strongly associated with chronic pain in active-duty servicewomen and female civilian dependents of military personnel on active duty; a lower socioeconomic status and mental health conditions further increased the likelihood of chronic pain.

METHODOLOGY:

• Researchers analyzed claims data from the Military Health System to identify chronic pain diagnoses among active-duty servicewomen and civilian dependents of individuals on active duty.
• A total of 3,473,401 individuals (median age, 29 years) were included in the study, with 644,478 active-duty servicewomen and 2,828,923 civilian dependents.
• The study compared the incidence of chronic pain during 2006-2013, a period of heightened deployment intensity, with 2014-2020, a period of reduced deployment intensity.
• The primary outcome was the diagnosis of chronic pain.

TAKEAWAY:

• Active-duty servicewomen in the years 2006-2013 had a 53% increase in the odds of reporting chronic pain compared with those in the period between 2014 and 2020 (odds ratio [OR], 1.53; 95% CI, 1.48-1.58).
• Civilian dependents in the years 2006-2013 had a 96% increase in the odds of chronic pain compared with those in the later interval (OR, 1.96; 95% CI, 1.93-1.99).
• In 2006-2013, junior enlisted active-duty servicewomen had nearly a twofold increase in the odds of chronic pain (OR, 1.95; 95% CI, 1.83-2.09), while junior enlisted dependents had more than a threefold increase in the odds of chronic pain (OR, 3.05; 95% CI, 2.87-3.25) compared with senior officers.
• Comorbid mental conditions also were associated with an increased odds of reporting chronic pain (OR, 1.67; 95% CI, 1.65-1.69).

Potential harms and benefits should be weighed carefully before women and their physicians decide on breast cancer screening, according to updated guidelines from the Canadian Task Force on Preventive Health Care.

The draft guidelines stem from a review of more than 165 recent randomized controlled trials, observational studies, mathematical models, and other data.

The guideline working group included four breast cancer experts (a medical oncologist, a radiation oncologist, a surgical oncologist, and a radiologist), three patient partners, six family physicians, a nurse practitioner, evidence review teams, and other experts.

To avoid potential conflicts of interest, the oncologists provided input but did not vote on the final recommendations, Guylène Thériault, MD, a family physician and chair of the task force and Breast Cancer Working Group, said in an interview. 

The guideline recommends that, after the potential benefits and harms of screening have been considered, mammography should be accessible every 2-3 years to women (ie, people assigned female at birth) between ages 40 and 74 years who are at average or moderately increased risk.

Women with a personal or extensive family history of breast cancer or genetic mutations that would increase breast cancer risk; those who have symptoms, such as a lump; those who feel they may be at high risk; and those who are transgender women should consult a healthcare provider about appropriate options, according to the updated guidelines, which do not apply to these patients.

The draft guidelines were published online on May 30 and are open for public comment until August 30.
 

‘Three Big Questions’

To develop the guidelines, the work group asked “three big questions,” said Dr. Thériault. The first was the effectiveness of breast cancer screening for women aged 40 years and over. For this question, this systematic review, unlike the 2018 guideline update, included not only randomized trials but also observational data to ensure that the work group considered all available data.

“The second question was about comparative effectiveness,” which is something the United States considered for the latest US Preventive Services Task Force (USPSTF) update, said Dr. Thériault. The USPSTF asked questions such as “What happens if we start screening patients at age 40 years? Or at age 50 years? What happens if we stop at age 74 years? Or if we use different tests such as 3D versus digital mammography?”

The Canadian Task Force relied on the evidence that the USPSTF found after grading it with its own criteria, she said. The results were similar, and so are the recommendations in this area. “For example, we don’t recommend supplementary screening for women with dense breasts because there are no studies to inform patient-oriented benefits.”

The third question was about the values and preferences of women regarding breast cancer screening, which is something the United States didn’t examine. “We had looked at that issue in 2018, and this time around, even though we expanded the type of studies, we got the same message: That there are differences between women in their 40s and those who are age 50 years and over.”

“The majority of women in their 40s think that the harms outweigh the benefits and are not interested in screening,” said Dr. Thériault. “But when I say the majority, that’s not every woman. So, we had to recognize that there is variability. And the majority, but not all, of women ages 50-74 years thinks the benefits are higher than the harms. That’s why we say in our recommendation that from ages 40 to 74, it’s a personal choice.”
 

Responding to Objections

Not surprisingly, the task force has heard objections to its draft guidelines. The first is that women aged 40-49 years are being denied mammograms, said Michelle Nadler, MD, a medical oncologist at Princess Margaret Cancer Centre in Toronto, Canada. “This [objection] has attained a lot of media coverage, which is unfortunate, because people who have not read the guidelines may believe this is true. The guidelines clearly state that an eligible, informed woman of this age group who wants a screening mammogram should receive one.”

The second commonly heard objection is that the task force is overestimating the harms of screening, such as anxiety and overdiagnosis, she said. But an outcome of “anxiety” was not factored into the guideline. Overdiagnosis was calculated on the basis of the literature, and estimates were converted to a common denominator so that they could be compared, said Dr. Nadler. The same was true of benefits.

Another objection was that screening could mean less need for chemotherapy or full axillary dissection, Dr. Nadler said. However, the task force did not find any primary studies that evaluated these outcomes.

Critics also said that the recommendations do not account for racial or ethnic variations. Although more research is likely needed in this area, “the task force states that individuals should be informed of all of their breast cancer risk factors, including race/ethnicity, and that this should be factored into decisions about screening,” said Dr. Nadler.

“I was very surprised that the task force was accused by some parties of paternalism,” added René Wittmer, MD, adjunct clinical professor of family medicine at the University of Montreal and chair of Choosing Wisely Quebec, Montreal, Canada. “In my opinion, the importance they place on shared decision-making is contrary to medical paternalism and aims to empower women to make a decision that fits with their values and preferences.”

Nevertheless, the inclusion of modeling studies and observational trials “may cause the potential benefits to be amplified, compared with what is seen in randomized controlled trials,” he said in an interview.
 

Decision Aids Help

Once the guidelines are finalized, decision aids will be available to patients and providers to help guide screening discussions, said Dr. Nadler. “Primary care providers need to be aware of an individual’s personal risk factors for breast cancer to know if they are at average, above average, or high lifetime risk of breast cancer. These guidelines do not apply to those with > 20% lifetime risk of breast cancer.”

“The standards for risk communication are in absolute numbers over a common denominator,” she noted. “This is how primary care providers discuss other important primary care topics like smoking cessation, cardiovascular disease (and decisions about statin medications), and osteoporosis risk. These same standards should apply for breast cancer screening.”

Furthermore, she said, providers “should be aware that individuals from marginalized communities may benefit from more than one conversation until they are able to make a decision about screening that is right for them.”

“There is good evidence showing that most advances we’ve seen in breast cancer outcomes (ie, reduction in breast cancer mortality) are likely due to improvements in treatment, not screening,” said Dr. Wittmer. “In fact, mortality reductions are seen even in age groups or countries where there is no routine screening. This means that women benefit from advances in treatments, whether they choose to get screened or not.”
 

‘Mammography Saves Lives’

Commenting on the updated guidelines, Janie Lee, MD, professor of radiology at the University of Washington School of Medicine and director of breast imaging at the Fred Hutchinson Cancer Center, both in Seattle, said: “For the USPSTF, benefits of life years gained were also considered, in addition to breast cancer deaths averted. To save more lives from breast cancer, guidelines may focus on screening women at older ages, when annual rates of breast cancer are higher.” By contrast, when thinking in terms of years of life saved, focusing on screening younger women, who have more years of life left, increases benefits. “Both are important outcomes that we want to improve with effective screening.”

That said, “we should follow the guidelines of our specific national organizations,” she continued. “Overall populations and healthcare systems are different between the US and Canada.”

For example, “the USPSTF specifically highlighted the potential for reducing breast cancer mortality in Black women, who are more likely to develop biologically aggressive tumors that are diagnosed at more advanced stages, when making updated recommendations earlier this year,” she said. “The Canadian guidelines did not make specific recommendations by race or ethnicity group, instead highlighting the need for more research on the impact of screening in these groups.”

In addition, “screening every year versus every other year is more routine in the US compared with Canada,” she noted. And nonmedical factors that influence health and that may influence access to medical care and timely diagnosis of breast cancer “may be different between our two countries.”

“The most important take-home message is that the scientific evidence is strong that screening mammography saves lives,” said Dr. Lee. “These new recommendations will hopefully result in more early diagnoses of breast cancer and save more lives. Screening works best when it’s used regularly, regardless of how frequently you return. Once you start screening, please urge your patients to plan to return.”

Dr. Nadler disclosed speaker honoraria and consulting fees from Novartis and Exact Sciences outside the scope of this interview and innovation funding from the NSH/UHN AMO Innovation Fund Competition for Developing and Implementing a Consensus Recommendation for Breast Cancer Screening Best Practices. Dr. Thériault is chair of the task force and chair of the working group for the draft guidelines. Dr. Wittmer is chair of Choosing Wisely Quebec. Dr. Lee reported no relevant financial relationships related to her interview.

Should 5 mg of tamoxifen — known as “baby TAM” — or the usual 20 mg dose be standard of care for breast cancer prevention in high-risk women?

Research to date clearly shows that tamoxifen can reduce the risk for breast cancer in high-risk individuals by 30%-50%. Recent evidence also indicates that this chemoprevention approach can reduce the risk of dying from breast cancer by as much as 57%.

In 2019, the US Preventive Services Task Force issued updated recommendations that clinicians offer risk-reducing medications, such as tamoxifen, raloxifene, or aromatase inhibitors, to women at an increased risk for breast cancer and a low risk for adverse medication effects.

However, this prophylactic strategy remains underused.

A major roadblock: The drugs’ side effects, which include venous thromboembolic events and endometrial cancer as well as symptoms of menopause, such as hot flashes and sexual issues, have made uptake and adherence a challenge.

Offering women a lower dose of tamoxifen could allay fears about toxicities and improve uptake as well as reduce side effects and boost long-term adherence among those receiving baby TAM.

However, experts remain uncertain about whether patients need the standard dose to experience the full prevention benefit.
 

The Debate

Years ago, Andrea De Censi, MD, a breast cancer researcher at the Galliera Hospital in Genova, Italy, and his colleagues reasoned that, because tamoxifen is a competitive estrogen receptor inhibitor, it may indeed have a minimal effective dose below 20 mg/d.

The fruits of that line of thought were presented to the world in the TAM-01 trial, first published in 2019, which pitted tamoxifen 5 mg/d for 3 years against placebo in 500 women with high-risk lesions, including lobular and ductal carcinoma in situ.

Dr. De Censi and colleagues found that baby TAM reduced the risk for invasive breast cancer by 52% and the risk for contralateral breast cancer by 75%.

Treatment adherence was slightly higher in the baby TAM group at 65% vs 61% in the placebo group.

A recent 10-year follow-up showed ongoing benefits associated with baby TAM vs placebo — a 42% reduction in breast cancer and a 64% drop in contralateral lesions.

The baby TAM group vs placebo experienced a slight increase in hot flashes but no significant increase in other common side effects.

Regarding serious adverse events, the baby TAM arm had one case of stage 1 endometrial cancer (0.4% of patients) and 20 cases of endometrial polyps (5%) vs 13 cases of endometrial polyps in the placebo arm. But there were no significant differences in thrombosis, cataracts, bone fractures, and other serious events.

Dr. De Censi said he’s surprised the baby TAM vs tamoxifen topic is still being debated. “Baby TAM, in my opinion, is a new standard of care for endocrine prevention of breast cancer in high-risk [women],” and baby TAM over 3 years is enough, said Dr. De Censi during a debate on the topic at the 2024 European Society for Medical Oncology Breast Cancer Congress in Berlin.

Gareth Evans, MD, a cancer genetics and prevention specialist at the University of Manchester, Manchester, England, however, isn’t convinced.

During the debate, Dr. Evans explained that  his main concern was that the baby TAM trial was limited to women with high-risk lesions, not other common reasons for tamoxifen prophylaxis, such as a positive family history or BRCA mutations.

“In Manchester, we have put over a thousand women on tamoxifen who have a family history or other risk factors, not high-risk lesions,” and there simply isn’t definitive evidence for baby TAM in these women, Dr. Evans said.

The vast weight of evidence for tamoxifen prophylaxis, he added, is in trials involving tens of thousands of women, followed in some cases for 20 years, who received the 20 mg dose for 5 years.

As a result, women in Manchester are started on 20 mg and dropped down to 5 mg only for side effects. That way, Evans explained, we are not taking away the benefit among women who can tolerate 20 mg.

Meanwhile, there’s no evidence that baby TAM improves medication adherence, he noted. Trials have reported similar adherence rates to baby TAM and standard dose tamoxifen as well as no definitive evidence that the risk for cancer and thrombosis is less with baby TAM, he said.

In fact, Dr. Evans noted, “many women take tamoxifen 20 mg for 5 years with no side effects.”

Overall, “I don’t think we’ve got the evidence yet to drop” dosages, particularly in women without high-risk lesions, Dr. Evans said. A real concern, he added, is poor metabolizers for whom 5 mg won’t be enough to have a preventive effect.

Dr. De Censi noted, however, that there will likely never be a definitive answer to the question of baby TAM vs standard dosing because industry has no financial incentive to do a head-to-head trial; tamoxifen went off patent over 30 years ago.

Still, a poll of the audience favored Evans’ approach — 80% said they would start high-risk women on 20 mg for breast cancer prophylaxis and reduce for side effects as needed.

Dr. De Censi didn’t have any disclosures. Dr. Evans is a consultant/advisor for AstraZeneca, SpringWorks, Recursion, Everything Genetic, and Syantra.

Bothersome urinary symptoms and incontinence at 12 months post partum are common and treatable, so screening for those symptoms as well as associated depression and anxiety is essential, write authors of a new study.

Sonia Bhandari Randhawa, MD, with the Department of Obstetrics and Gynecology, University of Texas Southwestern Medical Center in Dallas, led the study published in Urogynecology, which identified factors associated with persistent stress urinary incontinence (SUI), marked by leakage from sudden movements such as coughing or jumping; urgency UI (UUI), leakage after a sudden and intense need to urinate, even if the bladder isn’t full; and other overall bothersome urinary symptoms 1 year after delivery.
 

Associations by Subtype

Dr. Randhawa analyzed data provided by 419 patients (77% Hispanic White and 22% non-Hispanic Black). After multivariable analysis, SUI (n = 136, 32.5%) was significantly associated with greater body mass index (BMI) at the time of delivery and greater depression screening scores. Factors not associated included fetal birth weight, mode of delivery, degree of laceration, and breastfeeding status.

UUI (n = 69, 16.5%) was significantly associated with more births and higher anxiety screening scores. Women with overall urinary symptom bother also had significantly more births and higher anxiety screening scores.

“These findings support the [American College of Obstetricians and Gynecologists] recommendations for routine mental health and urinary incontinence screening in the postpartum period,” said Gena Dunivan, MD, director of the Division of Urogynecology and Pelvic Reconstructive Surgery at University of Alabama–Birmingham, who was not part of the study. “Routine screening for these issues will hopefully reduce the stigma, allowing more patients to receive the help they deserve.”
 

1 in 3 Postpartum Patients Affected by Urinary Incontinence

About one third of postpartum patients are affected by urinary incontinence, which is linked with poorer quality of life and mental health outcomes, the authors note.

Estimates of incontinence frequency post partum vary depending on the population studied, differences in subgroups, and definition of urinary incontinence. A strength of the study was its sizable population, made up almost entirely of Hispanic White and non-Hispanic Black women receiving care at a large safety-net hospital.

“This study has important clinical implications for postpartum patients,” the authors write. “Given an array of proven treatment options for both UUI and SUI, maternal health surveillance needs to include routine inquiry about UI to overcome patients’ reluctance for seeking care. Next, as elevated BMI was identified as a risk factor for persistent postpartum SUI, maintaining a healthy weight should be routinely encouraged during antenatal and postpartum clinic visits.”

Lauren Giugale, MD, director of UPMC’s Magee-Womens Hospital Postpartum Pelvic Floor Healing Clinic in Pittsburgh, Pennsylvania, says an important aspect of the study is that it measured urinary symptoms 1 year after delivery and shows that these symptoms persist. “A lot of studies look more short term,” she noted.

She also pointed to the study’s population of Black and Hispanic women, populations which “have been pretty hard to capture in urogynecology research. It’s important for us to understand these urinary symptoms are affecting those women as well as White women.”
 

Association With Anxiety

The association between postpartum depression scores and SUI is important, she says, but Dr. Randhawa’s team also “uniquely looked at anxiety scores in postpartum women. They showed an association between anxiety scores and UUI, so there’s certainly a potential impact of postpartum urinary symptoms on maternal mental health and maternal well-being.” The relationship between anxiety and depression and postpartum urinary symptoms is not well understood and warrants further research, she says.

In her role, Dr. Giugale says, she always asks about urinary symptoms, particularly in postpartum women. But she notes that some ob.gyn.s without urogynecology training may not prioritize those questions amid all the other information they need to cover.

She says she tells her residents to ask patients pointedly, “Are you having any urine leakage? Patients may not think it’s a problem that can be addressed. We do patients a disservice when we don’t ask the important questions that might potentially impact patients’ lives.”

The authors and Dr. Giugale and Dr. Dunivan report no relevant financial relationships.

TOPLINE:

Sedentary behavior, particularly sitting and watching television, is linked to lower odds of healthy aging, but substituting it with any physical activity — or even sleeping, in case of women with inadequate sleep — may lead to better overall health.

METHODOLOGY:

• Previous studies have shown that replacing sedentary behavior with physical activity may improve mortality outcomes, but whether this increased lifespan is accompanied by better overall health remains an unanswered question.
• To understand the impact of sedentary behavior and physical activity on healthy aging, researchers analyzed data from the prospective cohort Nurses’ Health Study.
• They included 45,176 women aged > 50 years in 1992 (mean age, 59.2 years) who were free of major chronic diseases and were followed up for 20 years.
• In 1992, validated questionnaires were used to record exposure to sedentary behavior, different levels of physical activity, and sleep. The time spent watching television was the primary exposure in the sedentary behavior category.
• The main outcome was healthy aging, defined as survival to ≥ 70 years of age and maintenance of four domains of health — being free of 11 main chronic diseases and having no impairment of subjective memory, physical function, or mental health.

TAKEAWAY:

• At 20 years of follow-up, 8.6% of the women achieved healthy aging, while 41.4% had none of the 11 chronic diseases, 16.1% had no physical function impairment, 44.1% had no mental health limitation, and 51.9% reported no memory impairment.
• For each increase of 2 hours per day spent sitting and watching television, the odds of healthy aging dropped by 12% (95% confidence interval [CI], 7%-17%).
• Conversely, every additional 2 hours per day of low-level physical activity at work upped the odds of healthy aging by 6% (95% CI, 3%-9%); furthermore, each extra hour per day of standardized moderate to vigorous physical activity (normal pace walking or the equivalent) was associated with 14% higher odds (95% CI, 11%-16%) of healthy aging.
• In a theoretical modeling analysis, individuals could increase their odds of healthy aging by replacing 1 hour of television time per day with low levels of physical activity at home and work or with moderate to vigorous levels of physical activity — or even sleeping, for those who slept for ≤ 7 hours.

IN PRACTICE:

“These findings expand on the literature reporting that replacing sedentary behavior with light or moderate to vigorous physical activity is associated with decreased mortality by suggesting that this increased lifespan might be accompanied by better overall health,” the authors wrote.

SOURCE:

Hongying Shi, PhD, Department of Epidemiology and Health Statistics, School of Public Health, Wenzhou Medical University, Wenzhou, China, led this study, which was published online in JAMA Network Open.

LIMITATIONS:

The measures of different behaviors were self-reported and may, therefore, be less accurate than objective measurement methods. Measurement error may have attenuated the effect of low levels of physical activity. The single exposure assessment at baseline may not reflect the long-term pattern of these activities.

DISCLOSURES:

The lead author was supported by the National Social Science Foundation Project of China and the Zhejiang Provincial Philosophy and Social Sciences Planning Project. A co-author and the Nurses’ Health Study were supported by the US National Institutes of Health. The authors declared no conflicts of interest.

LIMITATIONS:

The measures of different behaviors were self-reported and may, therefore, be less accurate than objective measurement methods. Measurement error may have attenuated the effect of low levels of physical activity. The single exposure assessment at baseline may not reflect the long-term pattern of these activities.

TOPLINE:

Sedentary behavior, particularly sitting and watching television, is linked to lower odds of healthy aging, but substituting it with any physical activity — or even sleeping, in case of women with inadequate sleep — may lead to better overall health.

METHODOLOGY:

• Previous studies have shown that replacing sedentary behavior with physical activity may improve mortality outcomes, but whether this increased lifespan is accompanied by better overall health remains an unanswered question.
• To understand the impact of sedentary behavior and physical activity on healthy aging, researchers analyzed data from the prospective cohort Nurses’ Health Study.
• They included 45,176 women aged > 50 years in 1992 (mean age, 59.2 years) who were free of major chronic diseases and were followed up for 20 years.
• In 1992, validated questionnaires were used to record exposure to sedentary behavior, different levels of physical activity, and sleep. The time spent watching television was the primary exposure in the sedentary behavior category.
• The main outcome was healthy aging, defined as survival to ≥ 70 years of age and maintenance of four domains of health — being free of 11 main chronic diseases and having no impairment of subjective memory, physical function, or mental health.

TAKEAWAY:

• At 20 years of follow-up, 8.6% of the women achieved healthy aging, while 41.4% had none of the 11 chronic diseases, 16.1% had no physical function impairment, 44.1% had no mental health limitation, and 51.9% reported no memory impairment.
• For each increase of 2 hours per day spent sitting and watching television, the odds of healthy aging dropped by 12% (95% confidence interval [CI], 7%-17%).
• Conversely, every additional 2 hours per day of low-level physical activity at work upped the odds of healthy aging by 6% (95% CI, 3%-9%); furthermore, each extra hour per day of standardized moderate to vigorous physical activity (normal pace walking or the equivalent) was associated with 14% higher odds (95% CI, 11%-16%) of healthy aging.
• In a theoretical modeling analysis, individuals could increase their odds of healthy aging by replacing 1 hour of television time per day with low levels of physical activity at home and work or with moderate to vigorous levels of physical activity — or even sleeping, for those who slept for ≤ 7 hours.
