Patients undergoing chimeric antigen receptor (CAR) T-cell therapy who develop potentially serious neurotoxicity from the therapy show elevated plasma levels of neurofilament light chain (NfL) prior to the treatment, suggesting a possibly important predictor of risk for the side effect.

“This is the first study to show NfL levels are elevated even before CAR T treatment is given,” first author Omar H. Butt, MD, PhD, of the Siteman Cancer Center at Barnes-Jewish Hospital and Washington University in St. Louis, said in an interview.

“While unlikely to be the sole driver of [the neurotoxicity], neural injury reflected by NfL may aid in identifying a high-risk subset of patients undergoing cellular therapy,” the authors concluded in the study, published in JAMA Oncology.

CAR T-cell therapy has gained favor for virtually revolutionizing the treatment of some leukemias and lymphomas, however, as many as 40%-60% of patients develop the neurotoxicity side effect, called immune effector cell–associated neurotoxicity syndrome (ICANS), which, though usually low grade, in more severe cases can cause substantial morbidity and even mortality.

Hence, “the early identification of patients at risk for ICANS is critical for preemptive management,” the authors noted.

NfL, an established marker of neuroaxonal injury in neurodegenerative diseases including multiple sclerosis and Alzheimer’s disease, has been shown in previous studies to be elevated following the development of ICANS and up to 5 days prior to its peak symptoms.

To further evaluate NfL elevations in relation to ICANS, Dr. Butt and colleagues identified 30 patients undergoing CD19 CART-cell therapy, including 77% for diffuse large B-cell lymphoma, at two U.S. centers: Washington University in St. Louis and Case Western Reserve University, Cleveland.

The patients had a median age of 64 and were 40% female.

Among them, four developed low-grade ICANS grade 1-2, and 7 developed ICANS grade 3 or higher.

Of those developing any-grade ICANS, baseline elevations of NfL prior to the CAR T-cell treatment, were significantly higher, compared with those who did not develop ICANs (mean 87.6 pg/mL vs. 29.4 pg/mL, P < .001), with no significant differences between the low-grade (1 and 2) and higher-grade (3 or higher) ICANS groups.

A receiver operating characteristic analysis showed baseline NfL levels significantly predicted the development of ICANS with high accuracy (area under the ROC curve, 0.96), as well as sensitivity (AUROC, 0.91) and specificity (AUROC, 0.95).

Notably, baseline NfL levels were associated with ICANS severity, but did not correlate with other factors including demographic, oncologic history, nononcologic neurologic history, or history of exposure to neurotoxic therapies.

However, Dr. Butt added, “it is important to note that our study was insufficiently powered to examine those relationships in earnest. Therefore, [a correlation between NfL and those factors] remains possible,” he said.

The elevated NfL levels observed prior to the development of ICANS remained high across the study’s seven time points, up to day 30 post infusion.
 

Interest in NfL levels on the rise

NfL assessment is currently only clinically validated in amyotrophic lateral sclerosis, where it is used to assess neuroaxonal health and integrity. However, testing is available as interest and evidence of NfL’s potential role in other settings grows.

Meanwhile, Dr. Butt and associates are themselves developing an assay to predict the development of ICANS, which will likely include NfL, if the role is validated in further studies.

“Future studies will explore validating NfL for ICANS and additional indications,” he said.

ICANS symptoms can range from headaches and confusion to seizures or strokes in more severe cases.

The current gold standard for treatment includes early intervention with high-dose steroids and careful monitoring, but there is reluctance to use such therapies because of concerns about their blunting the anticancer effects of the CAR T cells.

Importantly, if validated, elevations in NfL could signal the need for more precautionary measures with CAR T-cell therapy, Dr. Butt noted.

“Our data suggests patients with high NfL levels at baseline would benefit most from perhaps closer monitoring with frequent checks and possible early intervention at the first sign of symptoms, a period of time when it may be hard to distinguish ICANS from other causes of confusion, such as delirium,” he explained.
 

Limitations: Validation, preventive measures needed

Commenting on the study, Sattva S. Neelapu, MD, a professor and deputy chair of the department of lymphoma and myeloma at the University of Texas MD Anderson Cancer Center, Houston, agreed that the findings have potentially important implications.

“I think this is a very intriguing and novel finding that needs to be investigated further prospectively in a larger cohort and across different CAR T products in patients with lymphoma, leukemia, and myeloma,” Dr. Neelapu said in an interview.

The NfL elevations observed even before CAR T-cell therapy among those who went on to develop ICANS are notable, he added.

“This is the surprising finding in the study,” Dr. Neelapu said. “It raises the question whether neurologic injury is caused by prior therapies that these patients received or whether it is an age-related phenomenon, as we do see higher incidence and severity of ICANS in older patients or some other mechanisms.”

A key caveat, however, is that even if a risk is identified, options to prevent ICANS are currently limited, Dr. Neelapu noted.

“I think it is too early to implement this into clinical practice,” he said. In addition to needing further validation, “assessing NfL levels would be useful when there is an effective prophylactic or therapeutic strategy – both of which also need to be investigated.”

Dr. Butt and colleagues are developing a clinical assay for ICANS and reported a provisional patent pending on the use of plasma NfL as a predictive biomarker for ICANS. The study received support from the Washington University in St. Louis, the Paula and Rodger O. Riney Fund, the Daniel J. Brennan MD Fund, the Fred Simmons and Olga Mohan Fund; the National Cancer Institute, the National Multiple Sclerosis Society, and the National Institute of Neurological Disorders and Stroke. Dr. Neelapu reported conflicts of interest with numerous pharmaceutical companies.

Children born from frozen embryos may have increased cancer risk

Article Type

Wed, 09/21/2022 - 14:20

Children born after frozen-thawed embryo transfer (FET) may have a higher risk of cancer than children born through fresh embryo transfer or spontaneous conception, a large registry study suggests.

The results, however, “should be interpreted cautiously,” the authors noted, given the low number of cancer cases reported among children born using FET.

Still, the findings do “raise concerns considering the increasing use of FET, in particular freeze-all strategies without clear medical indications,” the authors concluded.

The study was published online in PLOS Medicine.

The number of children born after FET has increased globally and even exceeds the number of those born after fresh embryo transfer in many countries. In the United States, for instance, the FET rate has doubled since 2015; FETs constituted almost 80% of all embryo transfers using assisted reproductive technology (ART) without a donor in 2019.

Despite the benefits associated with FET, which include improved embryo survival and higher live birth rates, some previous research has hinted at a higher risk of childhood cancer in this population.

In the current study, researchers from the University of Gothenburg, Sweden, wanted to better understand the risk of childhood cancer following FET. The investigators analyzed data from 171,774 children born via ART, including 22,630 born after FET, as well as roughly 7.7 million children born after spontaneous conception in Denmark, Finland, Norway, and Sweden.

After a mean follow-up of about 10 years, the incidence rate of cancer diagnosed before age 18 years was 16.7 per 100,000 person-years for children born after spontaneous conception (16,184 cases) and 19.3 per 100,000 person-years for children born after ART (329 cases).

The researchers found no increased risk of cancer before age 18 years in the group of children conceived via ART compared with those conceived spontaneously.

However, children born after FET had a significantly higher risk of cancer compared with children born after fresh embryo transfer (adjusted hazard ratio [aHR], 1.59) and spontaneous conception (aHR, 1.65). Specifically with regard to ART, the incidence rate for those born after FET was 30.1 per 100,000 person-years – 48 total cases – compared with 18.8 per 1000,000 person-years after fresh embryo transfer.

Adjustment for macrosomia, birth weight, or major birth defects influenced the association only marginally.

For specific cancer types, children born after FET had more than a twofold higher risk for leukemia in comparison with those born after fresh embryo transfer (aHR, 2.25) and spontaneous conception (aHR, 2.22).

Still, the authors said these results should be interpreted “cautiously,” given the small number of children diagnosed with cancer after FET. The researchers also acknowledged that they do not know why children born after FET would face a higher risk of cancer.

These findings, however, do align with those from a 2019 Dutch population-based study. In the Dutch study, which included more than 24,000 ART-conceived children and more than 23,000 naturally conceived children, the risk of cancer after ART was not higher overall, but it was greater when only those conceived after FET were considered (aHR 1.80); this increased risk, however, was not statistically significant.

“Since the use of FET is substantially increasing, it is important to tease out whether the increased cancer risk is a true risk increase due to the ART procedures using FET, or due to chance or confounding by other factors,” authors of the 2019 Dutch study, Mandy Spaan, PhD, and Flora E. van Leeuwen, PhD, said in an interview.

“But, as childhood cancer is (fortunately) a rare disease, it is very difficult to study this research question among ART children due to limited numbers,” said Dr. Spaan and Dr. van Leeuwen, who are with the Netherlands Cancer Institute.

Given this, the two experts call for additional large population-based cohort studies to investigate the risk of cancer after ART, especially FET, and for a subsequent analysis that pools these data. They hope this strategy “will lead to reliable estimates” and provide information on the risks of FET in comparison with approaches that involve fresh embryos.

The current study had no commercial funding. The study authors as well as Dr. Spaan and Dr. van Leeuwen have disclosed no relevant financial relationships.

Children with sickle cell anemia not getting treatments, screening

Article Type
Changed
Wed, 09/21/2022 - 11:52

Fewer than half of children aged 2-16 years with sickle cell anemia are receiving recommended annual screening for stroke, a common complication of the disease, according to a new Vital Signs report from the Centers for Disease Control and Prevention.

Many of these children also are not receiving the recommended medication, hydroxyurea, which can reduce pain and acute chest syndrome and improve anemia and quality of life, according to the report released Sept. 20.

Sickle cell anemia (SCA) is the most severe form of sickle cell disease (SCD), which is a red blood cell disorder that primarily affects Black and African American people in the United States. It is associated with severe complications such as stroke, vison damage, frequent infections, and delayed growth, and a reduction in lifespan of more than 20 years.

SCD affects approximately 100,000 Americans and SCA accounts for about 75% of those cases.
 

Physician remembers her patients’ pain

In a briefing to reporters in advance of the report’s release, Debra Houry, MD, MPH, the CDC’s acting principal deputy director, recalled “long, tough nights with these young sickle cell warriors” in her career as an emergency department physician.

“[S]eeing children and teens suffering from the severe pain that often accompanies sickle cell anemia was heartbreaking,” she said.

She asked health care providers to confront racism as they build better systems for ensuring optimal treatment for children and adolescents with SCA.

“Health care providers can educate themselves, their colleagues, and their institutions about the specialized needs of people with sickle cell anemia, including how racism inhibits optimal care,” Dr. Houry said.

She said people with SCA report difficulty accessing care and when they do, they often report feeling stigmatized.

Lead author of the report, Laura Schieve, PhD, an epidemiologist with CDC’s National Center on Birth Defects and Developmental Disabilities, and colleagues looked at data from more than 3,300 children with SCA who were continuously enrolled in Medicaid during 2019. The data came from the IBM MarketScan Multi-State Medicaid Database.

In 2014, the National Heart, Lung, and Blood Institute (NHLBI) issued two key recommendations to prevent or reduce complications in children and adolescents with SCA.

One was annual screening of children and adolescents aged 2-16 years with transcranial Doppler (TCD) ultrasound to identify those at risk for stroke. The second was offering hydroxyurea therapy, which keeps red blood cells from sickling and blocking small blood vessels, to children and adolescents who were at least 9 months old to reduce pain and the risk for several life-threatening complications.

The researchers, however, found that in 2019, only 47% and 38% of children and adolescents aged 2-9 and 10-16 years, respectively, had TCD screening and 38% and 53% of children and adolescents aged 2-9 years and 10-16 years, respectively, used hydroxyurea.

“These complications are preventable – not inevitable. We must do more to help lessen the pain and complications associated with this disease by increasing the number of children who are screened for stroke and using the medication that can help reduce painful episodes,” said Karen Remley, MD, MPH, director of CDC’s National Center on Birth Defects and Developmental Disabilities, said in a press release.
 

 

 

Bridging the gap

Providers, parents, health systems, and governmental agencies all have roles in bringing evidence-based recommended care to young SCA patients, Dr. Houry noted.

Community organizations can also help connect families with resources and tools to increase understanding.

Dr. Schieve pointed to access barriers in that families may have trouble traveling to specialized centers where the TCD screening is given. In addition, appointments for the screening may be limited.

Children taking hydroxyurea must be monitored for the proper dosage of medication, she explained, and that can be logistically challenging as well.

Providers report they often don’t get timely information back from TCD screening programs to keep up with which children need their annual screening.

Overall, the nation lacks providers with expertise in SCD and that can lead to symptoms being dismissed, Dr. Schieve said.

Hematologists and others have a role in advocating for patients with governmental entities to raise awareness of this issue, she added.

It’s also important that electronic health records give prompts and provide information so that all providers who care for a child can track screening and medication for the condition, Dr. Schieve and Dr. Houry said.
 

New funding for sickle cell data collection

Recent funding to the CDC Sickle Cell Data Collection Program may help more people get appropriate care, Dr. Houry said.

The program is currently active in 11 states and collects data from people all over the United States with SCD to study trends and treatment access for those with the disease.

The data help drive decisions such as where new sickle cell clinics are needed.

“We will expand to more states serving more people affected by this disease,” Dr. Houry said.

The authors declared no relevant financial relationships.

Fewer than half of children aged 2-16 years with sickle cell anemia are receiving recommended annual screening for stroke, a common complication of the disease, according to a new Vital Signs report from the Centers for Disease Control and Prevention.

Many of these children also are not receiving the recommended medication, hydroxyurea, which can reduce pain and acute chest syndrome and improve anemia and quality of life, according to the report released Sept. 20.

Sickle cell anemia (SCA) is the most severe form of sickle cell disease (SCD), which is a red blood cell disorder that primarily affects Black and African American people in the United States. It is associated with severe complications such as stroke, vison damage, frequent infections, and delayed growth, and a reduction in lifespan of more than 20 years.

SCD affects approximately 100,000 Americans and SCA accounts for about 75% of those cases.
 

Physician remembers her patients’ pain

In a briefing to reporters in advance of the report’s release, Debra Houry, MD, MPH, the CDC’s acting principal deputy director, recalled “long, tough nights with these young sickle cell warriors” in her career as an emergency department physician.

“[S]eeing children and teens suffering from the severe pain that often accompanies sickle cell anemia was heartbreaking,” she said.

She asked health care providers to confront racism as they build better systems for ensuring optimal treatment for children and adolescents with SCA.

“Health care providers can educate themselves, their colleagues, and their institutions about the specialized needs of people with sickle cell anemia, including how racism inhibits optimal care,” Dr. Houry said.

She said people with SCA report difficulty accessing care and when they do, they often report feeling stigmatized.

Lead author of the report, Laura Schieve, PhD, an epidemiologist with CDC’s National Center on Birth Defects and Developmental Disabilities, and colleagues looked at data from more than 3,300 children with SCA who were continuously enrolled in Medicaid during 2019. The data came from the IBM MarketScan Multi-State Medicaid Database.

AAP guidance helps distinguish bleeding disorders from abuse

Article Type
Changed
Wed, 09/21/2022 - 09:01

 

In some cases, bruising or bleeding from bleeding disorders may look like signs of child abuse, but new guidance may help clinicians distinguish one from the other.

On Sept. 19 the American Academy of Pediatrics published two reports – a clinical report and a technical report – in the October 2022 issue of Pediatrics on evaluating for bleeding disorders when child abuse is suspected.

The reports were written by the AAP Section on Hematology/Oncology and the AAP Council on Child Abuse and Neglect.
 

One doesn’t rule out the other

The reports emphasize that laboratory testing of bleeding cannot always rule out abuse, just as a history of trauma (accidental or nonaccidental) may not rule out a bleeding disorder or other medical condition.

In the clinical report, led by James Anderst, MD, MSCI, with the division of child adversity and resilience, Children’s Mercy Hospital, University of Missouri–Kansas City, the researchers note that infants are at especially high risk of abusive bruising/bleeding, but bleeding disorders may also present in infancy.

The authors give an example of a situation when taking a thorough history won’t necessarily rule out a bleeding disorder: Male infants who have been circumcised with no significant bleeding issues may still have a bleeding disorder. Therefore, laboratory evaluations are often needed to detect disordered bleeding.

Children’s medications should be documented, the authors note, because certain drugs, such as nonsteroidal anti-inflammatory drugs, some antibiotics, antiepileptics, and herbal supplements, can affect tests that might be used to detect bleeding disorders.

Likewise, asking about restrictive or unusual diets or alternative therapies is important as some could increase the likelihood of bleeding/bruising.

Signs that bleeding disorder is not likely

The authors advise that, if a child has any of the following, an evaluation for a bleeding disorder is generally not needed:

  • Caregivers’ description of trauma sufficiently explains the bruising.
  • The child or an independent witness can provide a history of abuse or nonabusive trauma that explains the bruising.
  • The outline of the bruising follows an object or hand pattern.
  • The location of the bruising is on the ears, neck, or genitals.

“Bruising to the ears, neck, or genitals is rarely seen in either accidental injuries or in children with bleeding disorders,” the authors write.

Specification of which locations for injuries are more indicative of abuse in both mobile and immobile children was among the most important information from the paper, Seattle pediatrician Timothy Joos, MD, said in an interview.

Also very helpful, he said, was the listing of which tests should be done if bruising looks like potential abuse.

The authors write that if bruising is concerning for abuse that necessitates evaluation for bleeding disorders, the following tests should be done: PT (prothrombin time); aPTT (activated partial thromboplastin time); von Willebrand Factor (VWF) activity (Ristocetin cofactor); factor VIII activity level; factor IX activity level; and a complete blood count, including platelets.

“I think that’s what a lot of us suspected, but there’s not a lot of summary evidence regarding that until now,” Dr. Joos said.

 

 

Case-by-case decisions on when to test

The decision on whether to evaluate for a bleeding disorder may be made case by case.

If there is no obvious known trauma or intracranial hemorrhage (ICH), particularly subdural hematoma (SDH) in a nonmobile child, abuse should be suspected, the authors write.

They acknowledge that children can have ICH, such as a small SDH or an epidural hematoma, under the point of impact from a short fall.

“However,” the authors write, “short falls rarely result in significant brain injury.”

Conditions may affect screening tests

Screening tests for bleeding disorders can be falsely positive or falsely negative, the authors caution in the technical report, led by Shannon Carpenter, MD, MS, with the department of pediatrics, University of Missouri–Kansas City.

  • If coagulation laboratory test specimens sit in a hot metal box all day, for instance, factor levels may be falsely low, the authors explain.
  • Conversely, factors such as VWF and factor VIII are acute-phase reactants and factor levels will be deceptively high if blood specimens are taken in a stressful time.
  • Patients who have a traumatic brain injury often show temporary coagulopathy that does not signal a congenital disorder.

Vitamin K deficiency

The technical report explains that if an infant, typically younger than 6 months, presents with bleeding/bruising that raises flags for abuse and has a long PT, clinicians should confirm vitamin K was provided at birth and/or testing for vitamin K deficiency should be performed.

Not all states require vitamin K to be administered at birth and some parents refuse it. Deficiency can lead to bleeding in the skin or from mucosal surfaces from circumcision, generalized ecchymoses, and large intramuscular hemorrhages or ICH.

When infants don’t get vitamin K at birth, vitamin K deficiency bleeding (VKDB) is seen most often in the first days of life, the technical report states. It can also occur 1-3 months after birth.

“Late VKDB occurs from the first month to 3 months after birth,” the authors write. “This deficiency is more prevalent in breast-fed babies, because human milk contains less vitamin K than does cow milk.”

Overall, the authors write, extensive lab tests are usually not necessary, given the rarity of most bleeding disorders and specific clinical factors that decrease the odds that a bleeding disorder caused the child’s findings.

Dr. Joos said the decisions described in this paper are the kind that can keep pediatricians up at night.

“Any kind of guidance is helpful in these difficult cases,” he said. “These are scenarios that can often happen in the middle of the night, and you’re often struggling with evidence or past experience that can help you make some of these decisions.”

Authors of the reports and Dr. Joos declared no relevant financial relationships.

Newborns get routine heel blood tests, but should states keep those samples?

Article Type
Changed
Thu, 09/15/2022 - 15:15

Close to 4 million babies are born in the United States every year, and within their first 48 hours nearly all are pricked in the heel so their blood can be tested for dozens of life-threatening genetic and metabolic problems. The heel-stick test is considered such a crucial public health measure that states typically require it and parents aren’t asked for their permission before it’s done.

But the lab tests for newborn screenings generally don’t use all of the half-dozen or so drops of blood collected on filter paper cards. So states hold on to the leftover “dried blood spots,” as they’re called, often without parents’ knowledge or consent. In recent years, privacy-related concerns have grown about the sometimes decades-long storage and use of the material.

Some states allow the blood spots to be used in research studies, sometimes by third parties for a fee, or provided to law enforcement personnel investigating a crime. Permitting these or other uses without parents’ informed consent that they understand and agree to the use has prompted lawsuits from parents who want to make those decisions themselves and who seek to protect their children’s medical and genetic information.

In May, Michigan officials reportedly agreed to destroy more than 3 million blood spots as a partial settlement in a lawsuit brought by parents who said they didn’t receive enough clear information to provide informed consent for the blood to be used in research the state might conduct. The fate of millions of additional blood spots stored by the state will be determined at trial.

Philip L. Ellison, an attorney in Hemlock, Mich., who is spearheading the suit, said he became aware of the issue when his son was born 5 years ago. Mr. Ellison’s son, Patton, spent his first days in the neonatal intensive care unit after his blood sugar levels dropped precipitously after birth. The next morning, Mr. Ellison said, he was approached by a hospital staffer who asked whether he wanted to sign a consent form allowing the blood from Patton’s heel-stick test to be donated for research.

The unexpected request set off alarm bells for Mr. Ellison.

“We don’t know what the future will bring in terms of information that can be extracted from our blood,” he said. How the rules for using that blood might evolve over time is difficult to know. “A program that first starts out for one purpose, to test for disease, has now crept into medical research and then to law enforcement.”

Michigan is the rare state that asks parents for permission to use leftover newborn blood spots in research. Most do not, experts said. The state screens newborns for more than 50 diseases, such as cystic fibrosis and congenital hypothyroidism, because identifying and treating such illnesses early in a child’s life are crucial.

Afterward, whatever is left over is stored for up to 100 years and, if parents agree to it, may be used in research approved by the Michigan Department of Health and Human Services. Some recent studies have used deidentified blood spots to study the relationship between viral infection at birth and the development of autism later in life, as well as the impact of maternal exposure to manufactured chemicals known as PFAS on health outcomes.

Parents have also asked that their children’s blood spots be sent to researchers to help diagnose a disorder or to try to find a reason for a child’s death, said Chelsea Wuth, a spokesperson for the Michigan Department of Health and Human Services.

Michigan parents can request that the state destroy the leftover blood spots if they don’t want the state to hold on to them.

Since the 1960s, states have screened newborn blood for conditions that can lead to devastating physical or mental disabilities or death if they are not diagnosed and treated. The federal government recommends that roughly three dozen screening tests be performed, but some states conduct many more. Every year, an estimated 13,000 infants with serious medical conditions are identified through newborn screening programs, according to data published by the federal Centers for Disease Control and Prevention.

Many public health experts strongly support mandatory newborn screening as a critical component of infants’ clinical care. But some are receptive to giving parents a say in what happens to the blood after the screening.

“I have always believed that parents should be able to have the opportunity to say ‘yes’ or ‘no’ ” to having their newborns’ leftover blood used in research, said Beth Tarini, MD, a pediatrician and the associate director of the Center for Translational Research at Children’s National Research Institute in Washington, D.C. “Since it is not part of the clinical care, it is a different standard of engagement with the parents.”

In Michigan, 64% of parents consented to participate, according to court documents in Mr. Ellison’s case.

Encouraging people to participate is important, some public health experts say, because the blood spot repositories provide a rare opportunity for population-level research. People of European descent are often overrepresented in genetic databases, which can skew the results of studies. But the newborn screening program includes virtually everyone born in the United States.

“There’s strong evidence that research conducted on samples of white people creates disparities in the benefits of biomedical research for people who are not white,” said Kyle Brothers, MD, PhD, a pediatrician and bioethicist at Norton Children’s Research Institute in Louisville, Ky.

After privacy-related lawsuits were brought in 2009 and 2011 by parents in Texas and Minnesota, respectively, millions of blood spots were destroyed.

Brothers said an unwillingness to participate in research programs reflects larger trends, including more emphasis on the individual and less on contributing to the general good.

To those who might argue that parents’ privacy concerns are overblown, a recent lawsuit in New Jersey raises troubling questions.

In a public records lawsuit, the New Jersey Office of the Public Defender and the New Jersey Monitor, a nonprofit news site, charge that the state police used a subpoena to obtain an infant blood spot of a child who is now 9 years old from the state’s newborn screening laboratory. The lawsuit says a DNA analysis was conducted on the blood spot so evidence could be gathered against the child’s father, who was being represented by the public defender’s office, in connection with a sexual assault committed in 1996. The effort allowed police to get the DNA information without having to show a court probable cause, the suit alleges.

The lawsuit seeks to find out how often in the past 5 years New Jersey law enforcement agencies have used the newborn screening lab as a tool in investigations and subjected defendants to “warrantless searches and seizures.”

New Jersey keeps the records on file for 23 years, said CJ Griffin, a lawyer representing the public defender’s office and the New Jersey Monitor in the lawsuit.

Ms. Griffin said her clients aren’t challenging the program to test newborn blood for diseases. “It’s more the lack of transparency, and safeguards, and information about storage, and we don’t have any information about appropriate use.”

The New Jersey Department of Health doesn’t comment on pending litigation, spokesperson Nancy Kearney said. Ms. Kearney didn’t respond to a request for information about the state’s practices and policies related to the newborn screening program.

A recent Texas Law Review article found that more than a quarter of states lack policies on law enforcement access to newborn blood spot samples and related information and that nearly a third may allow access in certain circumstances.

In Michigan, the state gives law enforcement agencies dried blood spots only to identify the victim of a crime, Ms. Wuth said. “Typically, this means someone has been killed or gone missing,” she added.

Many clinicians and bioethicists say that standards for the use of blood spots need to be set.

“It’s nearly impossible for us to monitor the potential uses of our data,” said Andrew Crawford, senior policy counsel for the privacy and data project at the Center for Democracy and Technology. “That’s why need to put limitations on the use.”

Close to 4 million babies are born in the United States every year, and within their first 48 hours nearly all are pricked in the heel so their blood can be tested for dozens of life-threatening genetic and metabolic problems. The heel-stick test is considered such a crucial public health measure that states typically require it and parents aren’t asked for their permission before it’s done.

But the lab tests for newborn screenings generally don’t use all of the half-dozen or so drops of blood collected on filter paper cards. So states hold on to the leftover “dried blood spots,” as they’re called, often without parents’ knowledge or consent. In recent years, privacy-related concerns have grown about the sometimes decades-long storage and use of the material.

Some states allow the blood spots to be used in research studies, sometimes by third parties for a fee, or provided to law enforcement personnel investigating a crime. Permitting these or other uses without parents’ informed consent that they understand and agree to the use has prompted lawsuits from parents who want to make those decisions themselves and who seek to protect their children’s medical and genetic information.

In May, Michigan officials reportedly agreed to destroy more than 3 million blood spots as a partial settlement in a lawsuit brought by parents who said they didn’t receive enough clear information to provide informed consent for the blood to be used in research the state might conduct. The fate of millions of additional blood spots stored by the state will be determined at trial.

Philip L. Ellison, an attorney in Hemlock, Mich., who is spearheading the suit, said he became aware of the issue when his son was born 5 years ago. Mr. Ellison’s son, Patton, spent his first days in the neonatal intensive care unit after his blood sugar levels dropped precipitously after birth. The next morning, Mr. Ellison said, he was approached by a hospital staffer who asked whether he wanted to sign a consent form allowing the blood from Patton’s heel-stick test to be donated for research.

The unexpected request set off alarm bells for Mr. Ellison.

“We don’t know what the future will bring in terms of information that can be extracted from our blood,” he said. How the rules for using that blood might evolve over time is difficult to know. “A program that first starts out for one purpose, to test for disease, has now crept into medical research and then to law enforcement.”

Michigan is the rare state that asks parents for permission to use leftover newborn blood spots in research. Most do not, experts said. The state screens newborns for more than 50 diseases, such as cystic fibrosis and congenital hypothyroidism, because identifying and treating such illnesses early in a child’s life are crucial.

Afterward, whatever is left over is stored for up to 100 years and, if parents agree to it, may be used in research approved by the Michigan Department of Health and Human Services. Some recent studies have used deidentified blood spots to study the relationship between viral infection at birth and the development of autism later in life, as well as the impact of maternal exposure to manufactured chemicals known as PFAS on health outcomes.

Parents have also asked that their children’s blood spots be sent to researchers to help diagnose a disorder or to try to find a reason for a child’s death, said Chelsea Wuth, a spokesperson for the Michigan Department of Health and Human Services.

Michigan parents can request that the state destroy the leftover blood spots if they don’t want the state to hold on to them.

Since the 1960s, states have screened newborn blood for conditions that can lead to devastating physical or mental disabilities or death if they are not diagnosed and treated. The federal government recommends that roughly three dozen screening tests be performed, but some states conduct many more. Every year, an estimated 13,000 infants with serious medical conditions are identified through newborn screening programs, according to data published by the federal Centers for Disease Control and Prevention.

Many public health experts strongly support mandatory newborn screening as a critical component of infants’ clinical care. But some are receptive to giving parents a say in what happens to the blood after the screening.

Death Cafe in Hematology Oncology

Article Type
Changed
Thu, 12/15/2022 - 14:25

Introduction

Hematologists and oncologists (HO) face mortality daily. “Death Cafe” (DC) is a safe space set aside for open dialogue about death and dying. Despite origins outside the healthcare setting, DC has been used as a framework to help health care students and workers process death and dying. We aim to assess if DC sessions are perceived to have value by HO trainees and faculty.

Methods

HO fellows from Baylor College of Medicine (BCM) and HO Faculty from BCM, mostly those at the Houston Michael E. DeBakey Veterans Affairs Hospital (VA), were offered the opportunity to participate in the DC sessions. Our VA Cancer Center Chaplain was present for all sessions and helped facilitate the conversation. HO fellows who were invited to a DC and attended were emailed a survey questionnaire after the activity via survey monkey. The sessions and the surveys were not compulsory. Their participation in the session and completion of surveys implied informed consent. After IRB approval, we reviewed responses for the study groups. Sessions were held in person pre-pandemic in 2019 and virtually during the COVID-19 pandemic in 2022.

Results

Five fellows responded to our survey in 2019 and 7 in 2022 for a total of 12 respondents. 100% of respondents had been emotionally affected by a patient’s death. 82% had been emotionally affected by a patient’s death during the preceding 3 months. 90% had previously discussed their emotions relating to patient death with others. 83% would participate in DC again and 92% would recommend DC to a colleague. One 2019 participant commented that they thought attendings needed the session more than fellows, 2 2022 participants commented that they believe the meeting would be better in person. One 2022 participant commented they thought DC “is a good platform to vent emotions, identify self-destructive thoughts and better coping mechanisms.”

Conclusions 

DC provides a framework for HC to share personal and professional experience with mortality from a human perspective and support each other. This approach may be useful for HO departments or fellowships to offer as an opportunity to process end-of-life matters experienced as providers and finite humans.

Blood test for multiple cancers: Many false positives

Article Type
Changed
Mon, 09/12/2022 - 16:18

PARIS – New results from a large prospective trial give a better idea of how a blood test that can detect multiple cancers performs in a “real-life” setting.

“As this technology develops, people must continue with their standard cancer screening, but this is a glimpse of what the future may hold,” commented study investigator Deborah Schrag, MD, MPH, chair, department of medicine, Memorial Sloan Kettering Cancer Center, New York.

For the PATHFINDER study, the Galleri blood test (developed by Grail) was used in 6,621 healthy individuals aged over 50, with or without additional cancer risk factors (such as history of smoking or genetic risk).

It found a positive cancer signal in 92 individuals (1.4%). 

None of the individuals who tested positive was known to have cancer at the time of testing. Subsequent workup, which could include scans and/or biopsy, found cancer in 38% of those with a positive test.

“When the test was positive, the workups were typically done in less than 3 months,” Dr. Schrag commented, adding that “the blood test typically predicted the origin of the cancer.”

Dr. Schrag presented the findings at the annual meeting of the European Society for Medical Oncology (ESMO).

Approached for comment, Anthony J. Olszanski, MD, RPh, vice chair of research at the Fox Chase Cancer Center, Philadelphia, noted that the use of a blood test to “find” cancer has long been on the minds of patients. “It is not uncommon to hear oncology patients ask: ‘Why didn’t my doctor find my cancer earlier, on blood tests?’ ”

As this study suggests, finding a malignancy before it becomes apparent on imaging or because of symptoms is one step closer to becoming a reality. “But although this is an important study, it must be noted that only about 40% of patients with a positive test result were actually found to have cancer,” Dr. Olszanski said. “Conversely, about 60% of patients with a positive test result likely suffered from a considerable amount of anxiety that may persist even after further testing did not reveal a malignancy.”

Another important issue is that such testing may incur substantial health care cost. “Less than 2 participants per 100 had a positive test result, and those patients underwent further testing to interrogate the result,” he added. “It also remains unclear if detecting cancer early will lead to better outcomes.”

Whether or not the test will be cost-effective remains unknown, as Dr. Schrag emphasized they do not have a formal cost analysis at this time. “This technology is not ready for population-wide screening, but as the technology improves, costs will go down,” she said.

Dr. Schrag also added that this is a new concept and the trial shows it is feasible to detect cancer using a blood test. “It was not designed to determine if the test can decrease cancer mortality, which is obviously the purpose of screening, but it’s premature for that,” she said.
 

Details of the results

The Galleri test uses cell-free DNA and machine learning to detect a common cancer signal across more than 50 cancer types as well as to predict cancer signal origin.

Overall, the test detected a cancer signal in 1.4% (n = 92) of participants with analyzable samples.

A total of 90 participants underwent diagnostic testing (33 true positives and 57 false positives). Of the true positives, 81.8% underwent more than one invasive diagnostic test, as did 29.8% of false positives.

Specificity was 99.1%, positive predictive value (PPV) was approximately 40%, and 73% of those who were true positives had diagnostic resolution in less than 3 months.

Of the cancers that were diagnosed, 19 were solid tumors and 17 were hematologic cancers; 7 were diagnosed in a person with a history of cancer, 26 were cancer types without standard screening, and 14 were diagnosed at an early stage.

“What is exciting about this new paradigm is that many of these were cancers for which we don’t have standard screening,” said Dr. Schrag.

Dr. Schrag noted that given the immense interest in this study, the manufacturer is working toward refining the assay and improving the test. A reanalysis was conducted on all specimens using a refined version of the test.

“Importantly, the new analysis identified fewer patients with having positive signals, from 1.4% to 0.9%,” she said. “Specificity improved to 99.5% as did PPV – from 38% to 43.1% – and more people need to be screened to find a cancer – up to 263 from 189.”
 

False positives concerning

Previous, and very similar, results from the PATHFINDER trial were presented last year at the annual meeting of the American Society of Clinical Oncology.

Max Diehn, MD, PhD, associate professor of radiation oncology at Stanford (Calif.) University, was an invited discussant for the study.

He pointed out that there were more false positives than true positives and noted that “there were a significant number of invasive procedures in false positives, which could cause harm to these patients who don’t have cancer.”

Dr. Diehn also explained that most true positives were for lymphoid malignancies, not solid tumors, and it is not known whether early detection of lymphoid malignancy has clinical utility. 

The Galleri test is already available in the United States and is being offered by a number of U.S. health networks. However, it is not approved by the U.S. Food and Drug Administration and is not covered by medical insurance, so individuals have to pay around $950 for it out of pocket. 

Although some experts are excited by its potential, describing it as a “game-changer,” others are concerned that there are no clinical pathways in place yet to deal with the results of such a blood test, and say it is not ready for prime time. 

The study was funded by Grail, a subsidiary of Illumina. Dr. Shrag has reported relationships with Grail, the Journal of the American Medical Association, and Pfizer. Several coauthors also have disclosed relationships with industry. Dr. Olszanski has reported participating in advisory boards for BMS, Merck, and Instil Bio, and running trials for them.

“When the test was positive, the workups were typically done in less than 3 months,” Dr. Schrag commented, adding that “the blood test typically predicted the origin of the cancer.”

Dr. Schrag presented the findings at the annual meeting of the European Society for Medical Oncology (ESMO).

Approached for comment, Anthony J. Olszanski, MD, RPh, vice chair of research at the Fox Chase Cancer Center, Philadelphia, noted that the use of a blood test to “find” cancer has long been on the minds of patients. “It is not uncommon to hear oncology patients ask: ‘Why didn’t my doctor find my cancer earlier, on blood tests?’ ”

As this study suggests, finding a malignancy before it becomes apparent on imaging or because of symptoms is one step closer to becoming a reality. “But although this is an important study, it must be noted that only about 40% of patients with a positive test result were actually found to have cancer,” Dr. Olszanski said. “Conversely, about 60% of patients with a positive test result likely suffered from a considerable amount of anxiety that may persist even after further testing did not reveal a malignancy.”

Another important issue is that such testing may incur substantial health care cost. “Less than 2 participants per 100 had a positive test result, and those patients underwent further testing to interrogate the result,” he added. “It also remains unclear if detecting cancer early will lead to better outcomes.”

Whether or not the test will be cost-effective remains unknown, as Dr. Schrag emphasized they do not have a formal cost analysis at this time. “This technology is not ready for population-wide screening, but as the technology improves, costs will go down,” she said.

Dr. Schrag also added that this is a new concept and the trial shows it is feasible to detect cancer using a blood test. “It was not designed to determine if the test can decrease cancer mortality, which is obviously the purpose of screening, but it’s premature for that,” she said.
 

Details of the results

The Galleri test uses cell-free DNA and machine learning to detect a common cancer signal across more than 50 cancer types as well as to predict cancer signal origin.

Overall, the test detected a cancer signal in 1.4% (n = 92) of participants with analyzable samples.

A total of 90 participants underwent diagnostic testing (33 true positives and 57 false positives). Of the true positives, 81.8% underwent more than one invasive diagnostic test, as did 29.8% of false positives.

Specificity was 99.1%, positive predictive value (PPV) was approximately 40%, and 73% of those who were true positives had diagnostic resolution in less than 3 months.

Of the cancers that were diagnosed, 19 were solid tumors and 17 were hematologic cancers; 7 were diagnosed in a person with a history of cancer, 26 were cancer types without standard screening, and 14 were diagnosed at an early stage.

“What is exciting about this new paradigm is that many of these were cancers for which we don’t have standard screening,” said Dr. Schrag.

Dr. Schrag noted that given the immense interest in this study, the manufacturer is working toward refining the assay and improving the test. A reanalysis was conducted on all specimens using a refined version of the test.

“Importantly, the new analysis identified fewer patients with having positive signals, from 1.4% to 0.9%,” she said. “Specificity improved to 99.5% as did PPV – from 38% to 43.1% – and more people need to be screened to find a cancer – up to 263 from 189.”
 

False positives concerning

Previous, and very similar, results from the PATHFINDER trial were presented last year at the annual meeting of the American Society of Clinical Oncology.

Max Diehn, MD, PhD, associate professor of radiation oncology at Stanford (Calif.) University, was an invited discussant for the study.

He pointed out that there were more false positives than true positives and noted that “there were a significant number of invasive procedures in false positives, which could cause harm to these patients who don’t have cancer.”

Dr. Diehn also explained that most true positives were for lymphoid malignancies, not solid tumors, and it is not known whether early detection of lymphoid malignancy has clinical utility. 

The Galleri test is already available in the United States and is being offered by a number of U.S. health networks. However, it is not approved by the U.S. Food and Drug Administration and is not covered by medical insurance, so individuals have to pay around $950 for it out of pocket. 

Although some experts are excited by its potential, describing it as a “game-changer,” others are concerned that there are no clinical pathways in place yet to deal with the results of such a blood test, and say it is not ready for prime time. 

The study was funded by Grail, a subsidiary of Illumina. Dr. Shrag has reported relationships with Grail, the Journal of the American Medical Association, and Pfizer. Several coauthors also have disclosed relationships with industry. Dr. Olszanski has reported participating in advisory boards for BMS, Merck, and Instil Bio, and running trials for them.

PARIS – New results from a large prospective trial give a better idea of how a blood test that can detect multiple cancers performs in a “real-life” setting.

“As this technology develops, people must continue with their standard cancer screening, but this is a glimpse of what the future may hold,” commented study investigator Deborah Schrag, MD, MPH, chair, department of medicine, Memorial Sloan Kettering Cancer Center, New York.

For the PATHFINDER study, the Galleri blood test (developed by Grail) was used in 6,621 healthy individuals aged over 50, with or without additional cancer risk factors (such as history of smoking or genetic risk).

It found a positive cancer signal in 92 individuals (1.4%). 

None of the individuals who tested positive was known to have cancer at the time of testing. Subsequent workup, which could include scans and/or biopsy, found cancer in 38% of those with a positive test.

The Effect of Adjuvant Therapy Type on Survival for Patients With Sage II Osteosarcoma

Article Type
Changed
Thu, 12/15/2022 - 14:26

Background

Osteosarcoma is an aggressive bone malignancy often treated with surgery. On diagnosis, the majority of patients present with stage II disease. The objective of this study was to compare differences in survival between three commonly used adjuvant therapies: chemotherapy, radiation, and combined chemoradiation therapy in patients presenting with stage II disease.

Methods

The National Cancer Database (NCDB) was used to identify patients diagnosed with osteosarcoma from 2004 to 2018 using the ICD-O-3 histology codes 9180-9187. Patients with stage II disease and who had undergone a surgical procedure at the primary site were identified. Patients were grouped by the receipt of adjuvant chemotherapy, radiation, or chemoradiation. Descriptive statistics and Kaplan-Meier curves were used to measure survival in these patients. One way ANOVA and chi-square analyses were used to evaluate differences among treatment groups. Data were analyzed using SPSS and statistical significance was set at P = .05.

Results

Of 9955 patients in the NCDB diagnosed with osteosarcoma, 4378 (44%) presented with stage II disease. 710 (17.9%) of these surgical patients received additional adjuvant therapy. 66.0% received chemotherapy, 24.4% received radiation, and 9.57% received combined chemoradiation. Adjuvant chemotherapy had the longest median survival time of 91.7 months. Median survival for adjuvant radiotherapy was 48 months and combined chemoradiation was 50.5 months. On log-rank pairwise comparison, the difference in survival between adjuvant chemotherapy and adjuvant chemoradiation was found to be statistically significant. (P < .001). Patients receiving adjuvant chemotherapy were more likely to be younger and have private insurance. (P < .05) Conversely, patients receiving adjuvant radiation were more likely to be older and have Medicare. (P < .05). No significant differences were seen among patient race, sex, income, or Charleson-Deyo comorbidity score.

Conclusions

This study showed that patients with stage II osteosarcoma who receive adjuvant chemotherapy experience improved median survival in comparison to patients who receive adjuvant radiation. This is an important clinical finding, which should guide future treatment. However, further investigation is required to identify patient and treatment specific factors, which are contributing to mortality.

A Case Report of Palliative Pembrolizumab Monotherapy for a Poorly Differentiated Malignancy

Article Type
Changed
Thu, 12/15/2022 - 14:26

Introduction

 The critical role of palliative radiotherapy (RT) in the management of advanced cancer is evolving due to the advent of novel therapeuticapproaches. We report the case of a veteran with a soft tissue metastasis who had a robust response to pembrolizumab, allowing for the deferral of palliative RT. 

Case Presentation

An 86-year-old male presented with a rapidly growing, painful, malodorous, fungating right inguinal soft tissue mass measuring 10×7×3 cm that had rendered the patient non-ambulatory, with subsequent imaging also demonstrating a left pleural-based lung mass. Biopsy was consistent with a poorly differentiated carcinoma, and molecular profiling revealed a KRAS G12C mutation, high tumor mutational burden (TMB 18 mutations/megabase), and high PD-L1 expression (TPS 100%). The patient’s poor functional status precluded the use of aggressive combination chemotherapy, but the molecular features were favorable for response to immune checkpoint inhibitor monotherapy, which is better tolerated. He was initiated on pembrolizumab with the goal of symptom palliation and potentially prolonging his life. However, as rapid responses to immunotherapy are uncommon, radiation oncology was consulted for palliative RT. Twenty days after starting pembrolizumab and 2 weeks after RT simulation, the inguinal mass had markedly regressed with an open tissue defect at the site. As the palliative goal had been achieved, RT was deferred to avoid the development of a non-healing wound.

Conclusions

Our case highlights palliative treatment modalities for soft tissue masses. Immunotherapy is now a component of first-line therapy in many cancer types, but rapid and robust responses to monotherapy are rare. There is the exciting potential to combine immunotherapy with RT, with small case series indicating synergy, although further research is needed. In cases with molecular characteristics favoring response to immunotherapy, an optimal sequencing approach may incorporate an initial run-in phase with immunotherapy to determine if symptom palliation can be achieved with unimodal therapy. The location of the mass in a non-radiation sensitive region allowed us to entertain the use of combination therapy for our patient, but ultimately was not needed. Palliative RT will remain an option at the time of cancer progression.

Chimeric Antigen Receptor T-cell Therapy in the Veterans Affairs Network: the Tennessee Valley Healthcare System Experience

Article Type
Changed
Thu, 12/15/2022 - 14:26

Purpose/Background

Chimeric antigen receptor T-cell (CART) therapy has emerged as a novel treatment for hematologic malignancies, with six FDA agents approved for commercial use. The Veterans Affairs (VA) Tennessee Valley Healthcare System (TVHS) is the only VA facility authorized to administer CART therapy. As these therapies are changing the paradigm of treatment, the purpose of this review will report the TVHS experience thus far.

Methods

TVHS began coordination with pharmaceutical manufacturers of CART therapies upon first approval in 2017 and became an authorized treatment center for CART therapy in September 2019 with the first CART infusion performed in December of that year. This is a retrospective electronic chart review of all CART patients referred to TVHS from the program’s inception, December 1, 2019 through June 30, 2021. The primary objective of this analysis will be to evaluate the efficacy outcomes of veterans who received CART therapy at TVHS, including overall response rates (ORR), progression free survival (PFS), and overall survival (OS). Secondary objectives include assessment of toxicities, including rates and maximum grades of cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS).

Results

A total of 28 patients have received CART infusion at TVHS to date. Fifteen of these patients have reached one year post-CART infusion and are included in this analysis. The majority of patients were White (67%) and were treated for diffuse large B-cell lymphoma (87%). All patients were male and ten (67%) were over the age of 65. ORR was 93% (73% achieved complete response [CR]). One-year PFS and OS were both 60%. Of patients who achieved CR by day 100, 89% remain in CR to date. CRS toxicity was observed in 73% of patients (no Grade 3 or higher). ICANS was observed in 26.7% of patients (20% Grade 3 or higher).

Conclusions

CART therapy within the VA has become a well-established practice at TVHS and appears to be a safe and effective therapeutic option for veterans with aggressive lymphoid malignancies.
