Responsible use of breast cancer screening
In this edition of “Applying research to practice,” I examine a study suggesting that annual screening mammography does not reduce the risk of death from breast cancer in women aged 75 years and older. I also highlight a related editorial noting that we should optimize treatment as well as screening for breast cancer.
Regular screening mammography in women aged 50-69 years prevents 21.3 breast cancer deaths among 10,000 women over a 10-year time period (Ann Intern Med. 2016 Feb 16;164[4]:244-55). However, in the published screening trials, few participants were older than 70 years of age.
More than half of women above age 74 receive annual mammograms (Health, United States, 2018. www.cdc.gov/nchs/data/hus/hus18.pdf). And more than a third of breast cancer deaths occur in women aged 70 years or older (CA Cancer J Clin. 2016 Mar-Apr;66[2]:96-114).
Do older women benefit from annual mammography to the same extent as younger women? Is there a point at which benefit ends?
To answer these questions, Xabier García-Albéniz, MD, PhD, of Harvard Medical School in Boston, and colleagues studied 1,058,013 women enrolled in Medicare during 2000-2008 (Ann Intern Med. 2020 Feb 25. doi: 10.7326/M18-1199).
The researchers examined data on patients aged 70-84 years who had a life expectancy of at least 10 years, at least one recent mammogram, and no history of breast cancer. The team emulated a prospective trial by examining deaths over an 8-year period for women aged 70 years and older who either continued or stopped screening mammography. The researchers conducted separate analyses for women aged 70-74 years and those aged 75-84 years.
Diagnoses of breast cancer were, not surprisingly, higher in the continued-screening group, but there were no major reductions in breast cancer–related deaths.
Among women aged 70-74 years, the estimated 8-year risk for breast cancer death was reduced for women who continued screening versus those who stopped it by one death per 1,000 women (hazard ratio, 0.78). Among women aged 75-84 years, the 8-year risk reduction was 0.07 deaths per 1,000 women (HR, 1.00).
The authors concluded that continuing mammographic screening past age 75 years resulted in no material difference in cancer-specific mortality over an 8-year time period, in comparison with stopping regular screening examinations.
Considering treatment as well as screening
For a variety of reasons (ethical, economic, methodologic), it is unreasonable to expect a randomized, clinical trial examining the value of mammography in older women. An informative alternative would be a well-designed, large-scale, population-based, observational study that takes into consideration potentially confounding variables of the binary strategies of continuing screening versus stopping it.
Although the 8-year risk of breast cancer in older women is not low among screened women – 5.5% in women aged 70-74 years and 5.8% in women aged 75-84 years – and mammography remains an effective screening tool, the effect of screening on breast cancer mortality appears to decline as women age.
In the editorial that accompanies the study by Dr. García-Albéniz and colleagues, Otis Brawley, MD, of Johns Hopkins University, Baltimore, highlighted the role of inadequate, ineffective, inconvenient, or poorly tolerated treatment in older women (Ann Intern Med. 2020 Feb 25. doi: 10.7326/M20-0429).
Dr. Brawley illustrated that focusing too much on screening diverts attention from the major driver of cancer mortality in older women: suboptimal treatment. That certainly has been the case for the dramatic impact of improved lung cancer treatment on mortality, despite a statistically significant impact of screening on lung cancer mortality as well.
As with lung cancer screening, Dr. Brawley describes the goal of defining “personalized screening recommendations” in breast cancer, or screening that is targeted to the highest-risk women and those who stand a high chance of benefiting from treatment if they are diagnosed with breast cancer.
As our population ages and health care expenditures continue to rise, there can be little disagreement that responsible use of cancer diagnostics will be as vital as judicious application of treatment.

HPV vaccine-chemo combo prolongs cervical cancer survival
Longer survival was observed in women who had a stronger immune response to an investigational human papillomavirus (HPV) vaccine while treated with standard chemotherapy for advanced, metastatic, or recurrent cervical cancer.
The results, from a phase 1/2 study, showed that women with a vaccine-induced immune response higher than the median had a median overall survival of 16.8 months, compared with a median overall survival of 11.2 months for women with an immune response lower than the median (hazard ratio, 0.491; P = .012).
Cornelis “Kees” Melief, MD, chief scientific officer of ISA Pharmaceuticals in Leiden, the Netherlands, and colleagues reported these findings in Science Translational Medicine.
The researchers previously evaluated the HPV16 vaccine, ISA101, in combination with carboplatin and paclitaxel in a pilot study. Results showed that carboplatin and paclitaxel reduced abnormally high numbers of immunosuppressive myeloid cells, which allowed for “much stronger” ISA101-induced tumor immunity.
To investigate further, the researchers tested the chemotherapy-ISA101 combination in a phase 1/2 study (NCT02128126) of 79 women with advanced, metastatic, or recurrent HPV16-positive cervical cancer.
The patients received the vaccine 2 weeks after starting the second, third, and fourth cycles of chemotherapy. They received various doses of the vaccine (20, 40, 100, or 300 mcg) with or without pegylated type 1 interferon (1 mcg/kg body weight).
“ISA101 was generally safe and well tolerated in that its safety profile was not different from chemotherapy alone,” Dr. Melief and colleagues wrote.
Chemotherapy-associated adverse events occurred in 98.9% of patients, with more than 80% of patients reporting adverse events possibly related to the vaccine or interferon-alpha. However, less than 16% of patients withdrew from the study because of an adverse event.
Of the 72 patients evaluable for efficacy, 43% experienced tumor regression, and 43% had stable disease. The researchers observed regression of the target lesion in 29 of 59 patients with a measurable target lesion.
The team noted that, since all patients received chemotherapy, it is “difficult to interpret short-term clinical outcomes as being due to chemotherapy alone or to the combination,” although they noted that the use of interferon-alpha did not seem to provide any additional benefit.
“Eleven of 14 patients still alive at the end of the study displayed a strong vaccine-induced response and included 9 patients with FIGO stage IVa/IVb cancer who had a mean OS [overall survival] of 3 years,” the researchers noted.
Considering that patients with higher vaccine-induced immune responses lived longer, the researchers concluded that “chemoimmunotherapy can be exploited to the benefit of patients with advanced cancer based on a defined mode of action.”
This trial was funded by ISA Pharmaceuticals and a Dutch Cancer Society grant. Investigators disclosed relationships with ISA Pharmaceuticals and other companies.

Prospective algorithm favors vaginal hysterectomy
based on data from a prospective study of 365 patients.
“Total vaginal hysterectomy is the most cost-effective route, with a low complication rate, and, therefore, should be performed when feasible,” wrote Jennifer J. Schmitt, DO, of the Mayo Clinic, Rochester, Minn., and colleagues.
However, algorithms to support the decision to choose vaginal hysterectomy are not widely used, they said.
To assess the optimal surgical route for hysterectomy, the researchers devised a prospective algorithm and decision tree based on history of laparotomy, uterine size, and vaginal access. The results of their study were published in Obstetrics & Gynecology.
The study population included 365 women aged 18 years and older who underwent hysterectomies between Nov. 24, 2015, and Dec. 31, 2017, at a single center. A total of 202 patients (55%) met criteria for a total vaginal hysterectomy using the algorithm, and 57 (15.6%) were assigned to have an examination under anesthesia followed by total vaginal hysterectomy, for a total of 259 expected vaginal hysterectomies. Ultimately, 211 (81.5%) of the patients identified as being the best candidates for having a vaginal hysterectomy underwent the procedure. Almost all of the procedures – 99.1% – were completed successfully.
The algorithm predicted that 52 patients were expected to have an examination under anesthesia followed by a robot-assisted total laparoscopic hysterectomy and 54 were expected to have an abdominal, robotic, or laparoscopic hysterectomy. A total of 46 procedures (44 robotic, when vaginal was expected and 2 abdominal, when vaginal was expected) deviated to a more invasive route than prescribed by the algorithm, and 7 procedures deviated from the algorithm-predicted robotic or abdominal procedure to total vaginal hysterectomy.
Approximately 95% of the patients were discharged within 24 hours of surgery. These patients included 7 who had vaginal surgery when a more invasive method was predicted and did not experience intraoperative complications or Accordion grade 3 complications.
“Prospective algorithm use predicts that 55.3% of all hysterectomies were expected to have an a priori total vaginal hysterectomy, which is higher than the actual total vaginal hysterectomy rate of 11.5% reported previously,” the researchers noted, and they added that vaginal hysterectomy would be associated with cost savings of $657,524 if the total hysterectomy rate was 55% instead of 11%.
The study findings were limited by several factors including an expertise bias at the center where the study was conducted, as well as the small number of patients with algorithm deviations or poor outcomes, and the lack of a control group, the researchers noted. However, the results support the use of the algorithm “in combination with educating gynecologic surgeons about the feasibility of vaginal surgery,” they said.
“Prospective use of this algorithm nationally may increase the rate of total vaginal hysterectomy and decrease health care delivery costs,” they concluded.
“The American College of Obstetricians and Gynecologists continues to recommend vaginal hysterectomy as the approach of choice whenever feasible, and although clinical evidence and societal endorsements support vaginal hysterectomy as a superior high-value modality, the rate of vaginal hysterectomy in the United States has continued to decline,” Arnold P. Advincula, MD, of Columbia University Medical Center, New York, wrote in an accompanying editorial.
Many variables beyond clinical will determine the optimal hysterectomy route, Dr. Advincula said.
“Although historical evidence demonstrates that vaginal hysterectomy is associated with better outcomes when compared with other approaches, a multitude of studies now exist that challenge this notion. Given the financial implications and overall costs of care with surgical complications and 30-day readmissions, experienced high-volume surgeons using all available routes have shown robotics to be the best surgical approach in terms of fewer postoperative complications and lowest 30-day readmission rates,” he noted. However, “one should not split hairs and subtly pit one minimally invasive option against another, but instead should work toward the goal of minimizing laparotomy, which is still performed at a high rate,” Dr. Advincula emphasized.
The study was supported in part by the National Center for Advancing Translational Science. Dr. Schmitt had no financial conflicts to disclose. Dr. Advincula disclosed serving as a consultant for AbbVie, Baxter, ConMed, Eximis Surgical, Intuitive Surgical, and Titan Medical, and performing consultancy work and receiving royalties from Cooper Surgical.

Ultimately, 211 (81.5%) of the patients identified as being the best candidates for having a vaginal hysterectomy underwent the procedure. Almost all of the procedures – 99.1% – were completed successfully.
The algorithm predicted that 52 patients were expected to have an examination under anesthesia followed by a robot-assisted total laparoscopic hysterectomy and 54 were expected to have an abdominal, robotic, or laparoscopic hysterectomy. A total of 46 procedures (44 robotic, when vaginal was expected and 2 abdominal, when vaginal was expected) deviated to a more invasive route than prescribed by the algorithm, and 7 procedures deviated from the algorithm-predicted robotic or abdominal procedure to total vaginal hysterectomy.
Approximately 95% of the patients were discharged within 24 hours of surgery. These patients included 7 who had vaginal surgery when a more invasive method was predicted and did not experience intraoperative complications or Accordion grade 3 complications.
“Prospective algorithm use predicts that 55.3% of all hysterectomies were expected to have an a priori total vaginal hysterectomy, which is higher than the actual total vaginal hysterectomy rate of 11.5% reported previously,” the researchers noted, and they added that vaginal hysterectomy would be associated with cost savings of $657,524 if the total hysterectomy rate was 55% instead of 11%.
The study findings were limited by several factors including an expertise bias at the center where the study was conducted, as well as the small number of patients with algorithm deviations or poor outcomes, and the lack of a control group, the researchers noted. However, the results support the use of the algorithm “in combination with educating gynecologic surgeons about the feasibility of vaginal surgery,” they said.
“Prospective use of this algorithm nationally may increase the rate of total vaginal hysterectomy and decrease health care delivery costs,” they concluded.
“The American College of Obstetricians and Gynecologists continues to recommend vaginal hysterectomy as the approach of choice whenever feasible, and although clinical evidence and societal endorsements support vaginal hysterectomy as a superior high-value modality, the rate of vaginal hysterectomy in the United States has continued to decline,” Arnold P. Advincula, MD, of Columbia University Medical Center, New York, wrote in an accompanying editorial.
Many variables beyond clinical will determine the optimal hysterectomy route, Dr. Advincula said.
“Although historical evidence demonstrates that vaginal hysterectomy is associated with better outcomes when compared with other approaches, a multitude of studies now exist that challenge this notion. Given the financial implications and overall costs of care with surgical complications and 30-day readmissions, experienced high-volume surgeons using all available routes have shown robotics to be the best surgical approach in terms of fewer postoperative complications and lowest 30-day readmission rates,” he noted. However, “one should not split hairs and subtly pit one minimally invasive option against another, but instead should work toward the goal of minimizing laparotomy, which is still performed at a high rate,” Dr. Advincula emphasized.
The study was supported in part by the National Center for Advancing Translational Science. Dr. Schmitt had no financial conflicts to disclose. Dr. Advincula disclosed serving as a consultant for AbbVie, Baxter, ConMed, Eximis Surgical, Intuitive Surgical, and Titan Medical, and performing consultancy work and receiving royalties from Cooper Surgical.

Nearly half of STI events go without HIV testing
according to Danielle Petsis, MPH, of the Children’s Hospital of Philadelphia, and associates.
In a study published in Pediatrics, the investigators conducted a retrospective analysis of 1,816 acute STI events from 1,313 patients aged 13-24 years admitted between July 2014 and Dec. 2017 at two urban health care clinics. The most common STIs in the analysis were Chlamydia, gonorrhea, trichomoniasis, and syphilis; the mean age at diagnosis was 17 years, 71% of episodes occurred in females, and 97% occurred in African American patients.
Of the 1,816 events, HIV testing was completed within 90 days of the STI diagnosis for only 55%; there was 1 confirmed HIV diagnosis among the completed tests. When HIV testing did occur, in 38% of cases it was completed concurrently with STI testing or HIV testing was performed in 35% of the 872 follow-up cases. Of the 815 events where HIV testing was not performed, 27% had a test ordered by the provider but not completed by the patient; the patient leaving the laboratory before the test could be performed was the most common reason for test noncompletion (67%), followed by not showing up at all (18%) and errors in the medical record or laboratory (5%); the remaining patients gave as reasons for test noncompletion: declining an HIV test, a closed lab, or no reason.
Logistic regression showed that participants who were female and those with a previous history of STIs had significantly lower adjusted odds of HIV test completion, compared with males and those with no previous history of STIs, respectively, the investigators said. In addition, having insurance and having a family planning visit were associated with decreased odds of HIV testing, compared with not having insurance or a family planning visit.
“As we enter the fourth decade of the HIV epidemic, it remains clear that missed opportunities for diagnosis have the potential to delay HIV diagnosis and linkage to antiretroviral therapy or PrEP and prevention services, thus increasing the population risk of HIV transmission. Our data underscore the need for improved HIV testing education for providers of all levels of training and the need for public health agencies to clearly communicate the need for testing at the time of STI infection to reduce the number of missed opportunities for testing,” Ms. Petsis and colleagues concluded.
The study was supported by the National Institutes of Mental Health and the Children’s Hospital of Philadelphia Research Institute K-Readiness Award. One coauthor reported receiving funding from Bayer Healthcare, the Templeton Foundation, the National Institutes of Health, and Janssen Biotech. She also serves on expert advisory boards for Mylan Pharmaceuticals and Merck. The other authors have no relevant financial disclosures.

CV health in pregnancy improves outcomes for mother and infant
PHOENIX – according to results from a multinational cohort study.
“Over the past 10 years, cardiovascular health [CVH] has been characterized across most of the life course and is associated with a variety of health outcomes, but CVH as a whole has not been well studied during pregnancy,” Amanda M. Perak, MD, said at the Epidemiology and Prevention/Lifestyle and Cardiometabolic Health meeting.
In an effort to examine the associations of maternal gestational CVH with adverse maternal and newborn outcomes, Dr. Perak of the departments of pediatrics and preventive medicine at Northwestern University and Lurie Children’s Hospital, both in Chicago, and colleagues drew from the Hyperglycemia and Adverse Pregnancy Outcome (HAPO) Study, which examined pregnant women at a target of 28 weeks’ gestation and assessed the associations of glycemia with pregnancy outcomes. The researchers analyzed data from an ancillary study of 2,230 mother-child dyads to characterize clinical gestational CVH with use of five metrics: body mass index, blood pressure, cholesterol, glucose, and smoking. The study excluded women with prepregnancy diabetes, preterm births, and cases of fetal death/major malformations.
Each maternal CVH metric was classified as ideal, intermediate, or poor according to modified definitions based on pregnancy guidelines. “For lipids, it’s known that levels change substantially during pregnancy, but there are no pregnancy guidelines,” Dr. Perak said. “We and others have also shown that higher triglycerides in pregnancy are associated with adverse pregnancy outcomes. We selected thresholds of less than 250 mg/dL for ideal and at least 500 mg/dL for poor, based on triglyceride distribution and clinical relevance.”
Total CVH was scored by assigning 2 points for ideal, 1 for intermediate, and 0 for each poor metric, for a total possible 10 points, with 10 being most favorable. They also created four CVH categories, ranging from all ideal to two or more poor metrics. Maternal adverse pregnancy outcomes included preeclampsia and unplanned primary cesarean section. Newborn adverse pregnancy outcomes included birth weight above the 90th percentile and a cord blood insulin sensitivity index lower than the 10th percentile.
The researchers used logistic and multinomial logistic regression of pregnancy outcomes on maternal gestational CVH in two adjusted models. Secondarily, they examined associations of individual CVH metrics with outcomes, with adjustment for the other metrics.
The cohort comprised mother-child dyads from nine field centers in six countries: the United States (25%), Barbados (23%), United Kingdom (21%), China (18%), Thailand (7%), and Canada (7%). The mothers’ mean age was 30 years, and the mean gestational age was 28 weeks. The mean gestational CVH score was 8.8 out of 10. Nearly half of mothers (42%) had ideal metrics, while 4% had two or more poor metrics. Delivery occurred at a mean of 39.8 weeks, and adverse pregnancy outcomes occurred in 4.7%-17.9% of pregnancies.
In the fully adjusted model, which accounted for maternal age, height, alcohol use, gestational age at pregnancy exam, maternal parity, and newborn sex and race/ethnicity, odds ratios per 1-point higher (better) CVH score were 0.61 (95% confidence interval, 0.53-0.70) for preeclampsia, 0.85 (95% CI, 0.76-0.95) for unplanned primary cesarean section (among primiparous mothers), 0.83 (95% CI, 0.77-0.91) for large for gestational age infant, and 0.79 (95% CI, 0.72-0.87) for infant insulin sensitivity index below the 10th percentile. CVH categories were also associated with outcomes. For example, odds ratios for preeclampsia were 4.61 (95% CI, 2.13-11.14) for mothers with one or more intermediate metrics, 7.62 (95% CI, 3.60-18.13) for mothers with one poor metric, and 12.02 (95% CI, 4.70-32.50) for mothers with two or more poor metrics, compared with mothers with all metrics ideal.
“Except for smoking, each CVH metric was independently associated with adverse outcomes,” Dr. Perak said. “However, total CVH was associated with a wider range of outcomes than any single metric. This suggests that CVH provides health insights beyond single risk factors.”
Strengths of the study, she continued, included geographic and racial diversity of participants and high-quality research measurements of CVH. Limitations were that the cohort excluded prepregnancy diabetes and preterm births. “Diet and exercise data were not available, and CVH was measured once at 28 weeks,” she said. “Further study is needed across pregnancy and in other settings, but this study provides the first data on the relevance of gestational CVH for pregnancy outcomes.”
In an interview, Stephen S. Rich, PhD, who directs the Center for Public Health Genomics at the University of Virginia, said that the data “provide strong epidemiologic support to focus on the full range of cardiovascular health. In my view, the primary limitation of the study is that there may be significant differences in how one achieves ideal CHV across a single country, not to mention across the world, particularly in absence of a highly controlled, research environment. It is not clear that the approach used in this study at nine selected sites in six relatively highly developed countries could be translated into primary care – particularly in the U.S. with different regulatory and reimbursement plans and payers. Nonetheless, the evidence suggests a way to reduce adverse outcomes in pregnancy and the area deserves greater research.”
According to Dr. Perak, gestational diabetes is associated with a twofold higher maternal risk for cardiovascular disease (Diabetologia. 2019;62:905-14), while diabetes is also associated with higher offspring risk for CVD (BMJ. 2019;367:16398). However, a paucity of data exists on gestational CVH. In one report, better gestational CVH was associated with less subclinical CVD for the mother 10 years later (J Am Heart Assoc. 2019 Jul 23. doi:10.1161/JAHA.118.011394). In a separate analysis, Dr. Perak and her colleagues found that better gestational CVH was associated with better offspring CVH in childhood. “Unfortunately, we also reported that, among pregnant women in the United States, fewer than 1 in 10 had high CVH,” she said (J Am Heart Assoc. 2020 Feb 17. doi:10.1161/JAHA.119.015123). “However, the relevance of gestational CVH for pregnancy outcomes is unknown, but a it’s key question when considering CVH monitoring in prenatal care.”

Study supports genetic testing for all breast cancer patients age 65 and younger
Current National Comprehensive Cancer Network (NCCN) criteria may prevent genetic testing in “a substantial proportion” of women who carry germline pathogenic variants in breast cancer predisposition genes, according to investigators.
They found that, by expanding NCCN criteria to include germline genetic testing for all women diagnosed with breast cancer at age 65 or younger, the sensitivity of testing for nine well-established breast cancer predisposition genes would improve from 70% to more than 90%. The sensitivity for detection of BRCA1 and BRCA2 only would improve from 87% to greater than 98%.
Siddhartha Yadav, MD, of the Mayo Clinic, Rochester, Minn., and colleagues reported these findings in the Journal of Clinical Oncology.
“In a large unselected series of women with breast cancer, we demonstrate that expanding the NCCN testing criteria to include all women diagnosed with breast cancer at or before the age of 65 years has the potential to improve the sensitivity of germline genetic testing without the need for evaluation of all women with breast cancer,” Dr. Yadav and colleagues wrote.
Robert Pilarski, who was vice-chair of the panel that drew up the NCCN guidelines, said in an interview that the guideline authors tried to achieve a balance.
“We’ve known that NCCN misses cases and indications, but it comes down to whether the goal is to test all women with mutations or to have criteria that are a cost-effective and reasonable compromise to capture as many patients as possible,” said Mr. Pilarski, a licensed genetic counselor at the Ohio State University Wexner Medical Center in Columbus.
Current NCCN criteria for genetic/familial high-risk assessment for breast, ovarian, and pancreatic cancer recommend testing for individuals with blood relatives who have known or likely pathogenic variants, as well as patients with breast cancer diagnosed at age 45 or younger, patients aged 46-50 years with unknown or limited family history, patients with a second breast cancer diagnosed at any age, patients with triple-negative breast cancer diagnosed at age 60 or younger, and patients with breast cancer diagnosed at any age if they are of Ashkenazi Jewish ancestry.
But as Dr. Yadav and colleagues note, two recent studies (J Clin Oncol. 2019 Feb 20;37[6]:453-60; Ann Surg Oncol. 2018 Oct;25[10]:2925-31) suggested that up to 50% of germline pathogenic variants could be missed if testing were based solely on NCCN criteria.
Based on these findings, the American Society of Breast Surgeons issued a consensus guideline on genetic testing for hereditary breast cancer (Ann Surg Oncol. 2019 Oct;26[10]:3025-31), which states that, “genetic testing should be made available to all patients with a personal history of breast cancer.”
“Without question, if your goal is to identify everyone with a mutation, you’d have to test every cancer patient,” Mr. Pilarski said. “At this point, the ASBrS [American Society of Breast Surgeons] are the only group that have proposed that, and a lot of us feel that’s going too far at this point in time, and so the issue becomes what’s reasonable before that, and I think this paper is a great step forward.”
Cutting through the confusion
To see whether tweaking the existing guidelines could help clarify the issues surrounding genetic testing for breast cancer, Dr. Yadav and colleagues looked at a cohort of patients from the Mayo Clinic Breast Cancer Study. This prospective registry was open to all women evaluated at the Mayo Clinic Rochester for a first diagnosis of invasive breast cancer or ductal carcinoma in situ from May 2000 through May 2016.
The women were evaluated for germline pathogenic variants in nine breast cancer predisposition genes: ATM, BRCA1, BRCA2, CDH1, CHEK2, NF1, PALB2, PTEN, and TP53.
The researchers found that, of the 3,907 women in the sample, 1,872 (47.9%) would have been recommended for testing under the NCCN criteria, but the remaining 2,035 would not.
Women who met NCCN criteria were significantly more likely to carry a pathogenic variant (9% vs. 3.5%, P less than .001). However, 29.9% of women with pathogenic variants in the nine-gene panel and 13.1% of those with pathogenic variants in BRCA1 or BRCA2 did not qualify for testing by NCCN criteria.
The sensitivity of NCCN criteria was 70% for the nine-gene panel and 87% for BRCA 1 and BRCA 2, with a 53% specificity.
But if the criteria were expanded to include all women age 65 years and younger with a breast cancer diagnosis, the sensitivity for the nine-gene panel would increase to 92.1%, and the sensitivity for BRCA1 and BRCA2 only would climb to greater than 98.1%, with a specificity of approximately 22% for each test combination.
The authors acknowledged that they did not assess the cost-effectiveness of the testing criteria.
This study was supported by grants from the National Institutes of Health and the Breast Cancer Research Foundation. Authors disclosed relationships with Grail, bioTheranostics, Myriad Genetics, and other companies. Mr. Pilarski reported no conflicts of interest.

COVID-19 in children, pregnant women: What do we know?
A novel coronavirus, the causative agent of the current pandemic of viral respiratory illness and pneumonia, was first identified in Wuhan, Hubei, China. The disease has been given the name, coronavirus disease 2019 (COVID-19). The virus at last report has spread to more than 100 countries. Much of what we suspect about this virus comes from work on other severe coronavirus respiratory disease outbreaks – Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS). MERS-CoV was a viral respiratory disease, first reported in Saudi Arabia, that was identified in more than 27 additional countries. The disease was characterized by severe acute respiratory illness, including fever, cough, and shortness of breath. Among 2,499 cases, only two patients tested positive for MERS-CoV in the United States. SARS-CoV also caused a severe viral respiratory illness. SARS was first recognized in Asia in 2003 and was subsequently reported in approximately 25 countries. The last case reported was in 2004.
As of March 13, there are 137,066 cases worldwide of COVID-19 and 1,701 in the United States, according to the John Hopkins University Coronavirus COVID-19 resource center.
What about children?
The remarkable observation is how few seriously ill children have been identified in the face of global spread. Unlike the H1N1 influenza epidemic of 2009, where older adults were relatively spared and children were a major target population, COVID-19 appears to be relatively infrequent in children or too mild to come to diagnosis, to date. Specifically, among China’s first approximately 44,000 cases, less than 2% were identified in children less than 20 years of age, and severe disease was uncommon with no deaths in children less than 10 years of age reported. One child, 13 months of age, with acute respiratory distress syndrome and septic shock was reported in China. According to the Centers for Disease Control and Prevention webcast , children present with fever in about 50% of cases, cough, fatigue, and subsequently some (3%-30%) progress to shortness of breath. Some children and adults have presented with gastrointestinal disease initially. Viral RNA has been detected in respiratory secretions, blood, and stool of affected children; however, the samples were not cultured for virus so whether stool is a potential source for transmission is unclear. In adults, the disease appears to be most severe – with development of pneumonia – in the second week of illness. In both children and adults, the chest x-ray findings are an interstitial pneumonitis, ground glass appearance, and/or patchy infiltrates.
Are some children at greater risk? Are children the source of community transmission? Will children become a greater part of the disease pattern as further cases are identified and further testing is available? We cannot answer many of these questions about COVID-19 in children as yet, but as you are aware, data are accumulating daily, and the Centers for Disease Control and Prevention and the National Institutes of Health are providing regular updates.
A report from China gave us some idea about community transmission and infection risk for children. The Shenzhen CDC identified 391 COVID-19 cases and 1,286 close contacts. Household contacts and those persons traveling with a case of the virus were at highest risk of acquisition. The secondary attack rates within households was 15%; children were as likely to become infected as adults (medRxiv preprint. 2020. doi: 10.1101/2020.03.03.20028423).
What about pregnant women?
The data on pregnant women are even more limited. The concern about COVID-19 during pregnancy comes from our knowledge of adverse outcomes from other respiratory viral infections. For example, respiratory viral infections such as influenza have been associated with increased maternal risk of severe disease, and adverse neonatal outcomes, including low birth weight and preterm birth. The experience with SARS also is concerning for excess adverse maternal and neonatal complications such as spontaneous miscarriage, preterm delivery, intrauterine growth restriction, admission to the ICU, renal failure, and disseminated intravascular coagulopathy all were reported as complications of SARS infection during pregnancy.
Two studies on COVID-19 in pregnancy have been reported to date. In nine pregnant women reported by Chen et al., COVID-19 pneumonia was identified in the third trimester. The women presented with fever, cough, myalgia, sore throat, and/or malaise. Fetal distress was reported in two; all nine infants were born alive. Apgar scores were 8-10 at 1 minute. Five were found to have lymphopenia; three had increases in hepatic enzymes. None of the infants developed severe COVID-19 pneumonia. Amniotic fluid, cord blood, neonatal throat swab, and breast milk samples from six of the nine patients were tested for the novel coronavirus 2019, and all results were negative (Lancet. 2020 Feb 12. doi: 10.1016/S0140-6736[20]30360-3)https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)30360-3/fulltext.
In a study by Zhu et al., nine pregnant women with confirmed COVID-19 infection were identified during Jan. 20-Feb. 5, 2020. The onset of clinical symptoms in these women occurred before delivery in four cases, on the day of delivery in two cases, and after delivery in three cases. Of the 10 neonates (one set of twins) many had clinical symptoms, but none were proven to be COVID-19 positive in their pharyngeal swabs. Shortness of breath was observed in six, fever in two, tachycardia in one. GI symptoms such as feeding intolerance, bloating, GI bleed, and vomiting also were observed. Chest radiography showed abnormalities in seven neonates at admission. Thrombocytopenia and/or disseminated intravascular coagulopathy also was reported. Five neonates recovered and were discharged, one died, and four neonates remained in hospital in a stable condition. It is unclear if the illness in these infants was related to COVID-19 (Transl Pediatrics. 2020 Feb. doi: 10.21037/tp.2020.02.06)http://tp.amegroups.com/article/view/35919/28274.
In the limited experience to date, no evidence of virus has been found in the breast milk of women with COVID-19, which is consistent with the SARS experience. Current recommendations are to separate the infant from known COVID-19 infected mothers either in a different room or in the mother’s room using a six foot rule, a barrier curtain of some type, and mask and hand washing prior to any contact between mother and infant. If the mother desires to breastfeed her child, the same precautions – mask and hand washing – should be in place.
What about treatment?
There are no proven effective therapies and supportive care has been the mainstay to date. Clinical trials of remdesivir have been initiated both by Gilead (compassionate use, open label) and by the National Institutes of Health (randomized remdesivirhttps://www.drugs.com/history/remdesivir.html vs. placebo) in adults based on in vitro data suggesting activity again COVID-19. Lopinavir/ritonavir (combination protease inhibitors) also have been administered off label, but no results are available as yet.
Keeping up
I suggest several valuable resources to keep yourself abreast of the rapidly changing COVID-19 story. First the CDC website or your local Department of Health. These are being updated frequently and include advisories on personal protective equipment, clusters of cases in your local community, and current recommendations for mitigation of the epidemic. I have listened to Anthony S. Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, and Robert R. Redfield, MD, the director of the CDC almost daily. I trust their viewpoints and transparency about what is and what is not known, as well as the why and wherefore of their guidance, remembering that each day brings new information and new guidance.

A report from China gave us some idea about community transmission and infection risk for children. The Shenzhen CDC identified 391 COVID-19 cases and 1,286 close contacts. Household contacts and those persons traveling with a case of the virus were at highest risk of acquisition. The secondary attack rates within households was 15%; children were as likely to become infected as adults (medRxiv preprint. 2020. doi: 10.1101/2020.03.03.20028423).
What about pregnant women?
The data on pregnant women are even more limited. The concern about COVID-19 during pregnancy comes from our knowledge of adverse outcomes from other respiratory viral infections. For example, respiratory viral infections such as influenza have been associated with increased maternal risk of severe disease, and adverse neonatal outcomes, including low birth weight and preterm birth. The experience with SARS also is concerning for excess adverse maternal and neonatal complications such as spontaneous miscarriage, preterm delivery, intrauterine growth restriction, admission to the ICU, renal failure, and disseminated intravascular coagulopathy all were reported as complications of SARS infection during pregnancy.
Two studies on COVID-19 in pregnancy have been reported to date. In nine pregnant women reported by Chen et al., COVID-19 pneumonia was identified in the third trimester. The women presented with fever, cough, myalgia, sore throat, and/or malaise. Fetal distress was reported in two; all nine infants were born alive. Apgar scores were 8-10 at 1 minute. Five were found to have lymphopenia; three had increases in hepatic enzymes. None of the infants developed severe COVID-19 pneumonia. Amniotic fluid, cord blood, neonatal throat swab, and breast milk samples from six of the nine patients were tested for the novel coronavirus 2019, and all results were negative (Lancet. 2020 Feb 12. doi: 10.1016/S0140-6736[20]30360-3)https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)30360-3/fulltext.
In a study by Zhu et al., nine pregnant women with confirmed COVID-19 infection were identified during Jan. 20-Feb. 5, 2020. The onset of clinical symptoms in these women occurred before delivery in four cases, on the day of delivery in two cases, and after delivery in three cases. Of the 10 neonates (one set of twins) many had clinical symptoms, but none were proven to be COVID-19 positive in their pharyngeal swabs. Shortness of breath was observed in six, fever in two, tachycardia in one. GI symptoms such as feeding intolerance, bloating, GI bleed, and vomiting also were observed. Chest radiography showed abnormalities in seven neonates at admission. Thrombocytopenia and/or disseminated intravascular coagulopathy also was reported. Five neonates recovered and were discharged, one died, and four neonates remained in hospital in a stable condition. It is unclear if the illness in these infants was related to COVID-19 (Transl Pediatrics. 2020 Feb. doi: 10.21037/tp.2020.02.06)http://tp.amegroups.com/article/view/35919/28274.
In the limited experience to date, no evidence of virus has been found in the breast milk of women with COVID-19, which is consistent with the SARS experience. Current recommendations are to separate the infant from known COVID-19 infected mothers either in a different room or in the mother’s room using a six foot rule, a barrier curtain of some type, and mask and hand washing prior to any contact between mother and infant. If the mother desires to breastfeed her child, the same precautions – mask and hand washing – should be in place.
What about treatment?
There are no proven effective therapies and supportive care has been the mainstay to date. Clinical trials of remdesivir have been initiated both by Gilead (compassionate use, open label) and by the National Institutes of Health (randomized remdesivirhttps://www.drugs.com/history/remdesivir.html vs. placebo) in adults based on in vitro data suggesting activity again COVID-19. Lopinavir/ritonavir (combination protease inhibitors) also have been administered off label, but no results are available as yet.
Keeping up
I suggest several valuable resources to keep yourself abreast of the rapidly changing COVID-19 story. First the CDC website or your local Department of Health. These are being updated frequently and include advisories on personal protective equipment, clusters of cases in your local community, and current recommendations for mitigation of the epidemic. I have listened to Anthony S. Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, and Robert R. Redfield, MD, the director of the CDC almost daily. I trust their viewpoints and transparency about what is and what is not known, as well as the why and wherefore of their guidance, remembering that each day brings new information and new guidance.

Cancer mortality continues to decline while cancer incidence rises in women
according to the Annual Report to the Nation on the Status of Cancer.
During 2013-2017, the overall age-standardized death rate for all cancers was 158.2 per 100,000 population, and the average decline over that period was 1.5% per year. The average annual change was greater for men (–1.8%) than women (–1.4%) for 2013-2017, but the death rate was higher for men (189.3 per 100,000 vs. 135.5 per 100,000) for those years, S. Jane Henley of the Centers for Disease Control and Prevention and associates reported in Cancer.
“The drops in mortality we’re seeing are real, sustained, and a strong indication of what we can do when we work to prevent and treat cancer,” William G. Cance, MD, chief medical and scientific officer of the America Cancer Society, said in a written statement accompanying the report.
Overall cancer incidence for the most recent 5-year period (2012-2016) was 447.9 per 100,000, with rates of 487.9 for men and 421.4 for women, the investigators said.
Incidence dropped by 0.6% per year overall, but that hides a major difference between men, who saw a decrease of 1.0% a year, and women, who experienced an annual increase of 0.2%.
Over those 5 years, cancer incidence also increased by 0.8% annually among children aged 0-14 years and by 0.9% in adolescents and young adults aged 15-39 years, Ms. Henley and associates said in the report, which is a collaborative effort between the CDC, the National Cancer Institute, the American Cancer Society, and the North American Association of Central Cancer Registries.
“[W]e must not be complacent. The cancer incidence data – especially the increase in cancer among women – is a clear reminder that there is more work ahead,” Norman E. Sharpless, MD, director of the National Cancer Institute, said in the accompanying statement.

Botox: A new option for endometriosis pain?
NATIONAL HARBOR, MD. – Botulinum toxin injection into the vagina appears to relieve pain associated with endometriosis by relaxing the pelvic floor muscles, new research suggests.
In a randomized study, women with surgically diagnosed endometriosis who had chronic pelvic pain despite optimal surgical and hormonal treatment had less pain after injection vs their counterparts who received placebo.
This result suggests pelvic floor spasm may be an important factor in endometriosis-associated pelvic pain, the investigators note.
“Botulinum toxin injection offers an alternative approach for women with pelvic pain,” lead author Barbara Illowsky Karp, MD, National Institute of Neurological Disorders and Stroke, National Institutes of Health, Bethesda, Md., told Medscape Medical News.
“We focused on endometriosis, but there are reasons to think it may be effective for pelvic pain from other causes if there is spasm of the muscle,” said Karp, a neurologist who has used botulinum toxin therapeutically since it was first developed in the 1980s.
She noted that it is unknown whether the toxin will work in women who do not have actual spasm, “but the effect on spasm is not the sole effect of toxin,” as demonstrated by its use in other pain conditions.
“It seems to have a direct effect on the pain pathways in the nervous system as well,” Karp added.
The study findings were presented here at the American Academy of Pain Medicine (AAPM) 2020 Annual Meeting.
Less pain
The investigators randomly assigned 29 women between the ages of 18 and 50 years to receive injections with 100 U onabotulinumtoxinA (n = 15) or saline placebo (n = 14).
All of the women had endometriosis with chronic pelvic pain lasting at least 3 months (mean time, 6 years) and confirmed pelvic floor spasm as a main pain generator.
One month after treatment, participants were asked if they had improvement in their pain.
“Our primary outcome was just simply asking the women if they felt better or not, because we were blinded as to what treatment they received. One month is typically when the toxin reaches its maximal effect,” Karp said.
At 1 month, 11 women in the placebo group reported that they had no benefit, compared with only 4 women in the botulinum toxin group (P = .027).
The botulinum toxin group reported a greater degree of benefit compared with the placebo group (P = .030) and greater percent of improvement (P = .034).
Neither group reported substantial changes in pain rating on the visual analog scale. However, a definite pain score is often difficult to measure in women with chronic pelvic pain, coinvestigator Pamela Stratton, MD, a gynecologist in Bethesda, said.
“Some women report their pain as a 2, some as an 8. Also, women may have a lot of pain one day and not have that much pain another day, and how do you measure that? This is why we have not focused solely on the pain score but instead wanted the women to tell us if they were improved or not,” Stratton told Medscape Medical News.
Disability worsened considerably in the placebo group, but remained consistent in the botulinum toxin group. Five patients in the botulinum toxin group were able to reduce pain medication compared with one patient in the placebo group.
“Compelling” findings but early days
Commenting on the findings for Medscape Medical News, Ann E. Hansen, MD, Chronic Pain Wellness Center, Phoenix VA Health Care System, Arizona, noted that this “preliminary study” showed some benefit for a complex and challenging-to-treat syndrome.
“Injection of botulinum toxin prevents local muscle contraction, thus effectively relieving a variety of neuromuscular conditions such as torticollis; spasticity; pain syndromes such as headache and migraine; and some neurologic disorders, for instance, overactive bladder,” said Hansen, who was not involved with the research.
“Using botulinum toxin injection to target pelvic floor muscle spasm, a known pain generator in women suffering from chronic pelvic pain, makes sense. Future studies will be helpful in elucidating optimal treatment protocols for this debilitating condition,” she added.
Also commenting for Medscape Medical News, Kathryn T. Hall, PhD, MPH, Brigham & Women’s Hospital, Boston, Massachusetts, called the results “quite compelling” although, “it’s still early days.”
“It remains to be seen if the treatment effect will endure or if side effects will emerge. Hopefully all will go well,” Hall said.
The study was funded by an unrestricted grant from the National Institutes of Health. Allergan provided the botulinum toxin that was used in the study. Karp, Stratton, Hansen, and Hall have disclosed no relevant financial relationships.

Antifungal drug appears safe for pregnancy
Treatment with the according to results from a large registry study in Denmark.
Physicians have been reluctant to prescribe the drug during pregnancy because of the limited safety data. The drug has not been associated with any signs of fetal toxicity in animal studies, but only one study – in 54 pregnancies – has examined the issue in humans and did not identify an increased fetal risk, according to Niklas Worm Andersson, MD, of the department of clinical pharmacology, Copenhagen University Hospital at Bispebjerg and Frederiksberg, and coauthors.
The retrospective, nationwide cohort study analyzed exposure to oral and tropical terbinafine in a large pregnancy registry and found no increase in the risk of major malformations or spontaneous abortions in exposed versus unexposed pregnancies. The study was published in JAMA Dermatology.
Still, these results fell short of certainty, the authors noted. “Although our results may provide reassurance for pregnancies exposed to oral terbinafine by reporting no overall increased risk of major malformations, we cannot exclude a potential increased risk of a specific malformation,” they wrote.
“To our knowledge, this is by far the largest, most statistically rigorous study in the literature regarding this topic,” Jenny E. Murase, MD, of the department of dermatology at the University of California, San Francisco, and Mary Kathryn Abel, a medical student at UCSF, wrote in an accompanying editorial. They described the study as “a substantial contribution to the nearly absent literature regarding the use of terbinafine during pregnancy. Among the antifungal medications, it is possible that terbinafine is the safest one currently available for use in pregnancy, particularly of the oral formulations.”
However, since asymptomatic onychomycosis “is typically a cosmetic, rather than medical, concern, waiting until after pregnancy to initiate therapy is reasonable. ... It is important to acknowledge the uncertainty in this field and question the appropriateness of treating non–life-threatening diseases during pregnancy and lactation,” they wrote.
The Danish researchers drew from a registry of 1,650,649 pregnancies between 1997 and 2016, which included 891 pregnancies exposed to oral terbinafine, and 3,174 exposed to topical terbinafine. Matched outcome analyses compared the exposed pregnancies with up to 40,650 controls unexposed during pregnancy.
Propensity-matched comparisons showed no increased risk of major malformations for oral terbinafine exposure versus no exposure (odds ratio, 1.01; 95% confidence interval, 0.63-1.62) or topical exposure versus no exposure (OR, 1.08; 95% CI, 0.81-1.44). There was also no difference in oral versus topical exposure (OR, 1.18; 95% CI, 0.61-2.29).
With respect to spontaneous abortions, there was no significant association with oral terbinafine (hazard ratio, 1.06; 95% CI, 0.86-1.32) or topical terbinafine (HR, 1.04; 95% CI, 0.88-1.21), compared with unexposed pregnancies, or oral over topical terbinafine-exposed pregnancies (HR, 1.19; 95% CI, 0.84-1.70).
The study is limited by the fact that it was conducted in a Danish population, and the data relied on filled prescriptions for determining exposure, which did not account for adherence. Residual confounding is possible because of the retrospective nature of the study, the authors pointed out.
No source of funding was disclosed. One of the authors has received grants and personal fees from Novartis. Dr. Murase has received fees from Sanofi Genzyme, Dermira, UCB, Regeneron, Ferndale, and UpToDate.

Murase, MD, of the department of dermatology at the University of California, San Francisco, and Mary Kathryn Abel, a medical student at UCSF, wrote in an accompanying editorial. They described the study as “a substantial contribution to the nearly absent literature regarding the use of terbinafine during pregnancy. Among the antifungal medications, it is possible that terbinafine is the safest one currently available for use in pregnancy, particularly of the oral formulations.”
However, since asymptomatic onychomycosis “is typically a cosmetic, rather than medical, concern, waiting until after pregnancy to initiate therapy is reasonable. ... It is important to acknowledge the uncertainty in this field and question the appropriateness of treating non–life-threatening diseases during pregnancy and lactation,” they wrote.
The Danish researchers drew from a registry of 1,650,649 pregnancies between 1997 and 2016, which included 891 pregnancies exposed to oral terbinafine, and 3,174 exposed to topical terbinafine. Matched outcome analyses compared the exposed pregnancies with up to 40,650 controls unexposed during pregnancy.
Propensity-matched comparisons showed no increased risk of major malformations for oral terbinafine exposure versus no exposure (odds ratio, 1.01; 95% confidence interval, 0.63-1.62) or topical exposure versus no exposure (OR, 1.08; 95% CI, 0.81-1.44). There was also no difference in oral versus topical exposure (OR, 1.18; 95% CI, 0.61-2.29).
With respect to spontaneous abortions, there was no significant association with oral terbinafine (hazard ratio, 1.06; 95% CI, 0.86-1.32) or topical terbinafine (HR, 1.04; 95% CI, 0.88-1.21), compared with unexposed pregnancies, or oral over topical terbinafine-exposed pregnancies (HR, 1.19; 95% CI, 0.84-1.70).
The study is limited by the fact that it was conducted in a Danish population, and the data relied on filled prescriptions for determining exposure, which did not account for adherence. Residual confounding is possible because of the retrospective nature of the study, the authors pointed out.
