About a third of Americans say they’ve skipped medical care that they needed in the past 3 months because of concerns about the cost, according to a new survey from Gallup and West Health.

That’s the highest reported number since the pandemic began and a tripling from March to October.

Even 20% of the country’s highest-income households – earning more than $120,000 per year – said they’ve also skipped care. That’s an increase of about seven times for higher-income families since March.

“Americans tend to think there is a group of lower-income people, and they have worse health care than the rest of us, and the rest of us, we’re okay,” Tim Lash, chief strategy officer for West Health, a nonprofit focused on lowering health care costs, told CBS News.

“What we are seeing now in this survey is this group of people who are identifying themselves as struggling with health care costs is growing,” he said.

As part of the 2021 Healthcare in America Report, researchers surveyed more than 6,000 people in September and October about their concerns and experiences with affording health care and treatment. About half of respondents said health care in America has gotten worse because of the pandemic, and more than half said they’re more worried about medical costs than before.

What’s more, many Americans put off routine doctor visits at the beginning of the pandemic, and now that they’re beginning to schedule appointments again, they’re facing major costs, the survey found. Some expenses have increased in the past year, including prescription medications.

The rising costs have led many people to skip care or treatment, which can have major consequences. About 1 in 20 adults said they know a friend or family member who died during the past year because they couldn’t afford medical care, the survey found. And about 20% of adults said they or someone in their household had a health issue that grew worse after postponing care because of price.

About 23% of survey respondents said that paying for health care represents a major financial burden, which increases to a third of respondents who earn less than $48,000 per year. Out-of-pocket costs such as deductibles and insurance premiums have increased, which have taken up larger portions of people’s budgets.

“We often overlook the side effect of costs, and it’s quite toxic – there is a financial toxicity that exists in health care,” Mr. Lash said. “We know when you skip treatment, that can have an impact on mortality.”

Based on data from a meta-analysis of 95 studies that included nearly 30,000,000 individuals, the pooled percentage of asymptomatic COVID-19 infections was 0.25% in the tested population and 40.5% among confirmed cases.

Asymptomatic infections remain potential sources of transmission for COVID-19, especially as communities reopen and public life resumes, but the percentage of these infections among those tested and among those diagnosed with COVID-19 has not been examined, wrote Qiuyue Ma, PhD, and colleagues of Peking University, Beijing.

In a study published in JAMA Network Open the researchers identified 44 cross-sectional studies, 41 cohort studies, seven case series, and three case series on transmission studies. A total of 74 studies were conducted in developed countries, including those in Europe, North America, and Asia. Approximately one-third (37) of the studies were conducted among health care workers or in-hospital patients, 17 among nursing home staff or residents, and 14 among community residents. In addition, 13 studies involved pregnant women, eight involved air or cruise ship travelers, and six involved close contacts of individuals with confirmed infections.

The meta-analysis included 29,776,306 tested individuals; 11,516 of them had asymptomatic infections.

Overall, the pooled percentage of asymptomatic infections among the tested population was 0.25%. In an analysis of different study populations, the percentage was higher in nursing home residents or staff (4.52%), air or cruise ship travelers (2.02%), and pregnant women (2.34%), compared against the pooled percentage.

The pooled percentage of asymptomatic infections among the confirmed population was 40.50%, and this percentage was higher in pregnant women (54.11%), air or cruise ship travelers (52.91%), and nursing home residents or staff (47.53%).

The pooled percentage in the tested population was higher than the overall percentage when the mean age of the study population was 60 years or older (3.69%). By contrast, in the confirmed population, the pooled percentage was higher than the overall percentage when the study population was younger than 20 years (60.2%) or aged 20 to 39 years (49.5%).

The researchers noted in their discussion that the varying percentage of asymptomatic individuals according to community prevalence might impact the heterogeneity of the included studies. They also noted the high number of studies conducted in nursing home populations, groups in which asymptomatic individuals were more likely to be tested.

The study findings were limited by several factors, including the potential for missed studies that were not published at the time of the meta-analysis, as well as the exclusion of studies written in Chinese, the researchers noted. Other limitations included lack of follow-up on presymptomatic and covert infections, and the focus on specific populations, factors that may limit the degree to which the results can be generalized.

However, the results highlight the need to screen for asymptomatic infections, especially in countries where COVID-19 has been better controlled, the researchers said. Management strategies for asymptomatic infections, when identified, should include isolation and contact tracing similar to strategies used with confirmed cases, they added. 
 

More testing needed to catch cases early

“During the initial phase of [the] COVID-19 pandemic, testing was not widely available in the United States or the rest of the world,” Setu Patolia, MD, of Saint Louis University School of Medicine, Missouri, said in an interview. Much of the world still lacks access to COVID-19 testing, and early in the pandemic only severely symptomatic patients were tested, he said. “With new variants, particularly the Omicron variant, which may have mild or minimally symptomatic disease, asymptomatic carriers play an important role in propagation of the pandemic,” he explained. “It is important to know the asymptomatic carrier rate among the general population for the future control of [the] pandemic,” he added.

Dr. Patolia said he was surprised by the study finding that one in 400 people in the general population could be asymptomatic carriers of COVID-19.

“Also, nursing home patients are more at risk of complications of COVID, and I expected that they would have a higher rate of symptomatic disease as compared to [the] general population,” said Dr. Patolia. He was also surprised by the high rate of asymptomatic infections in travelers.

“Physicians should be more aware about the asymptomatic carrier rate, particularly in travelers and nursing home patients,” he noted. “Travelers carry high risk of transferring infection from one region to another region of the world, and physicians should advise them to get tested despite the absence of symptoms,” Dr. Patolia emphasized. “Similarly, once any nursing home patient has been diagnosed with COVID-19, physicians should be more careful with the rest of the nursing home patients and test them despite the absence of the symptoms,” he added.

Dr. Patolia also recommended that pregnant women wear masks to help prevent disease transmission when visiting a doctor’s office or labor unit.

Looking ahead, there is a need for cheaper at-home testing kits so that all vulnerable populations can be tested fast and frequently, Dr. Patolia said.

The study was supported by the National Natural Science Foundation of China. The researchers had no financial conflicts to disclose. Dr. Patolia has disclosed no relevant financial relationships.

In the United States, nearly 4 million women a year prepare to give birth, looking forward to the joy to come. But for some, the dream turns tragic. About 700 women die each year either during their pregnancy or in the weeks after the birth. And another 60,000 have pregnancy-related or childbirth-related health issues.

Causes of death vary greatly, including hemorrhage during pregnancy or during delivery, heart conditions, and mental health issues such as substance abuse and suicide after the birth.

In 2019, the U.S. maternal death rate was 20.1 per 100,000 women, according to the CDC, significantly higher than the 17.4 per 100,000 recorded in 2018. For Black women, the maternal death rate was more than double the overall – 44 per 100,000 in 2019.

“We have to address our horrendous maternal health care system and also need to address the inequities,” says Laurie Zephyrin, MD, vice president for advancing health equity for the Commonwealth Fund, a foundation supporting independent research on health care issues. “This is an issue that has needed national attention for a long time.”

“If we look overall, our maternal death rate is more than twice that of more than 10 other high-income countries,” she said.

As sobering as the problem is, recent developments have sparked hope that reversing the course is possible. Among them:

U.S. News & World Report, long known for its rankings of hospitals, issued its first ever “Best Hospitals for Maternity” rankings Dec. 7, highlighting facilities that perform well on key quality indicators. It plans to update the report annually.

At the first-ever White House Maternal Health Day of Action on Dec. 7, Vice President Kamala Harris urged a call to action to reduce maternal deaths and pregnancy-related health problems, with extension of postpartum coverage through Medicaid programs, among other actions.

A new hospital designation called ‘’Birthing Friendly” will be established by the Centers for Medicare & Medicaid Services. The label will be given to facilities that take part in a program aimed at improving maternal outcomes and that use patient safety practices.

President Joe Biden’s proposed Build Back Better plan includes maternal health provisions, including $3 billion in new maternal health funding. The money will aim to grow and diversify the workforce caring for pregnant women, coordinate care better, and step up research on maternal health, among other projects.

Ongoing efforts in Congress are aimed at fixing the wide disparities in maternal health affecting Black women. Regardless of income level or education, Black women are at a higher risk of maternal death and other health issues than are White women. A Black woman with a college education is at 60% higher risk of maternal death than a White or Hispanic woman who didn’t graduate high school, according to the Commonwealth Fund.
 

Best hospitals for maternity

For its rankings, U.S. News and World Report reached out to the 2,700 U.S. hospitals that offer maternity services, said Ben Harder, chief of health analysis and managing editor at U.S. News & World Report.

To be recognized, a hospital had to submit data from 2019 and meet the publication’s maternity care standards. The publication received responses from just 571 hospitals, representing about two of every five births in the country.

Of those, 237 were identified as best for maternity.

As to why the response rate was not higher, Mr. Harder cited the reporting burden and says it is understandable. Some hospitals likely did not have the staff available, especially during the pandemic, to gather the data needed to be evaluated by U.S. News & World Report.

On their other evaluations, the rankings are based on Medicare data, “so hospitals don’t have to lift a finger.” He expects more hospitals will respond for their future evaluations of maternity care.

The evaluators focused on five quality measures, making a score based on the cesarean section delivery rate among first-time mothers, early elective delivery rates, unexpected newborn complication rates, breastfeeding rates, and option for vaginal birth after C-section.
 

A call to action: Expand coverage

Speaking at the White House Maternal Health Day of Action, Mrs. Harris told participants: “The challenge is urgent, and it is important, and it will take all of us.”

Being pregnant and giving birth, she said, should not carry such great risks. She zeroed in on systemic inequities in the way women are treated and the dramatic impact maternal death and health issues have on the economy.

“A healthy economy requires healthy mothers and healthy babies,” Mrs. Harris said.

“Before, during, and after childbirth, women in our nation are dying at a higher rate than any other developed nation in our world,” she said, noting that research shows that Black women, Native Americans, and women in rural America more likely to suffer.

A major strategy in the call to action, according to Mrs. Harris, is encouraging states to expand postpartum coverage to pregnant women enrolled in Medicaid or the Children’s Health Insurance Program from the existing 60 days to a full year. Together, these two programs cover over 42% of births in the country, so expanding the coverage is expected to have a great impact.

The 60 days of coverage is not enough, as many deaths and complications happen more than 60 days after childbirth, Mrs. Harris said. The logistics for states to extend coverage were established by the American Rescue Plan and will become available by April 2022. Some states have already extended the postpartum coverage.

According to the Centers for Medicare and Medicaid Services, if every state did adopt an extension, as the Build Back Better Act proposes, the number of Americans getting coverage for a full year after childbirth would about double, extending the coverage for about 720,000 each year.
 

Congressional actions

Congress is working on the issue as well. The Black Maternal Health Momnibus Act of 2021, for instance, proposes several measures, including improving maternal nutrition, expanding affordable housing, and extending the maternal workforce to include more doulas and midwives.

“And for so many women, let’s note doulas are literally a lifeline,” Mrs. Harris said at the White House event.

Doulas are trained to offer women physical, emotional, and informational support before, during, and after childbirth. No reliable statistics are available on their numbers in the United States, but a March of Dimes report estimates that about 9,000 were included in a registration database in 2018.
 

Explaining and fixing the disparities

No one can explain for sure why Black women, in particular, are at higher risk of dying from pregnancy-related complications. Systemic inequity is one likely reason, Mrs. Harris said, noting there are differences in how people are treated based on who they are.

Inherent and unconscious bias in offering women treatment plays a role, experts say. Training could reverse or reduce that bias. Some women of color also may have less access to care, as do women in some rural areas.

According to Mrs. Harris, more than 20 companies and nonprofits have pledged to invest more than $20 million in maternal health efforts in the United States and more than $150 million globally. Among the proposed programs: remote-care monitors in rural areas, better care models for the postpartum period, and improved education programs for maternal health providers.
 

When statistics hit home

Many who work to improve maternal health have gone through issues themselves or had loved ones who did.

Jill Arnold, founder of the Maternal Safety Foundation in Bentonville, Ark., became a consumer advocate after giving birth to her two daughters, now teenagers. With the first birth, Ms. Arnold said she was intensely pressured at the last minute to have a C-section. She held out, resisted, and delivered a healthy baby vaginally.

For her second childbirth, she chose an accredited birth center that allowed her to have a doula and a midwife.

“The care I received was night and day,” she said. “The overwhelming pressure to consent to a C-section wasn’t there.”

She welcomes the information provided by the new U.S. News & World Report rankings as well as the upcoming “Birthing Friendly” designations.

“The onus shouldn’t be on patients, on individuals, on pregnant people to do the research,” Ms. Arnold said.

Rather, women and their partners need information at their fingertips so they can make an informed decision about how to give birth and where.

U.S. Rep. Lauren Underwood (D-Ill.), who cofounded the Black Maternal Health Caucus in April 2019, with Rep. Alma Adams (D-N.C.), wrote a touching blog in the journal Health Affairs to explain her passion in improving maternal health.

Her former classmate, Shalon Irving, who went on to become a CDC epidemiologist, died in February 2017 at age 36, just 3 weeks after giving birth, when she developed complications from high blood pressure.

In the blog, Ms. Underwood cited statistics and provides details of the Black Maternal Health Momnibus Act of 2021, then ends the blog, published in 2020, with an update on how Ms. Irving’s then 3-year-old daughter, raised by her grandmother, is doing. While Soleil is “curious, joyful, and brilliant,” the grandmother told Ms. Underwood that she has also walked into a room and found the little girl clutching a framed photograph of her mother.

The child’s question is understandable and heartbreaking: She wants to know where her mommy is.

“Soleil’s question is my motivation,” Ms. Underwood wrote. “To honor Shalon, and all the women like her who we have lost, let us take the serious and urgent action that is required to save our moms.”

For its rankings, U.S. News and World Report reached out to the 2,700 U.S. hospitals that offer maternity services, said Ben Harder, chief of health analysis and managing editor at U.S. News & World Report.

To be recognized, a hospital had to submit data from 2019 and meet the publication’s maternity care standards. The publication received responses from just 571 hospitals, representing about two of every five births in the country.

Of those, 237 were identified as best for maternity.

As to why the response rate was not higher, Mr. Harder cited the reporting burden and says it is understandable. Some hospitals likely did not have the staff available, especially during the pandemic, to gather the data needed to be evaluated by U.S. News & World Report.

On their other evaluations, the rankings are based on Medicare data, “so hospitals don’t have to lift a finger.” He expects more hospitals will respond for their future evaluations of maternity care.

The evaluators focused on five quality measures, making a score based on the cesarean section delivery rate among first-time mothers, early elective delivery rates, unexpected newborn complication rates, breastfeeding rates, and option for vaginal birth after C-section.
 

A call to action: Expand coverage

Speaking at the White House Maternal Health Day of Action, Mrs. Harris told participants: “The challenge is urgent, and it is important, and it will take all of us.”

Being pregnant and giving birth, she said, should not carry such great risks. She zeroed in on systemic inequities in the way women are treated and the dramatic impact maternal death and health issues have on the economy.

“A healthy economy requires healthy mothers and healthy babies,” Mrs. Harris said.

“Before, during, and after childbirth, women in our nation are dying at a higher rate than any other developed nation in our world,” she said, noting that research shows that Black women, Native Americans, and women in rural America more likely to suffer.

A major strategy in the call to action, according to Mrs. Harris, is encouraging states to expand postpartum coverage to pregnant women enrolled in Medicaid or the Children’s Health Insurance Program from the existing 60 days to a full year. Together, these two programs cover over 42% of births in the country, so expanding the coverage is expected to have a great impact.

The 60 days of coverage is not enough, as many deaths and complications happen more than 60 days after childbirth, Mrs. Harris said. The logistics for states to extend coverage were established by the American Rescue Plan and will become available by April 2022. Some states have already extended the postpartum coverage.

According to the Centers for Medicare and Medicaid Services, if every state did adopt an extension, as the Build Back Better Act proposes, the number of Americans getting coverage for a full year after childbirth would about double, extending the coverage for about 720,000 each year.
 

Congressional actions

Congress is working on the issue as well. The Black Maternal Health Momnibus Act of 2021, for instance, proposes several measures, including improving maternal nutrition, expanding affordable housing, and extending the maternal workforce to include more doulas and midwives.

“And for so many women, let’s note doulas are literally a lifeline,” Mrs. Harris said at the White House event.

Doulas are trained to offer women physical, emotional, and informational support before, during, and after childbirth. No reliable statistics are available on their numbers in the United States, but a March of Dimes report estimates that about 9,000 were included in a registration database in 2018.
 

Explaining and fixing the disparities

No one can explain for sure why Black women, in particular, are at higher risk of dying from pregnancy-related complications. Systemic inequity is one likely reason, Mrs. Harris said, noting there are differences in how people are treated based on who they are.

Inherent and unconscious bias in offering women treatment plays a role, experts say. Training could reverse or reduce that bias. Some women of color also may have less access to care, as do women in some rural areas.

According to Mrs. Harris, more than 20 companies and nonprofits have pledged to invest more than $20 million in maternal health efforts in the United States and more than $150 million globally. Among the proposed programs: remote-care monitors in rural areas, better care models for the postpartum period, and improved education programs for maternal health providers.
 

When statistics hit home

Many who work to improve maternal health have gone through issues themselves or had loved ones who did.

Jill Arnold, founder of the Maternal Safety Foundation in Bentonville, Ark., became a consumer advocate after giving birth to her two daughters, now teenagers. With the first birth, Ms. Arnold said she was intensely pressured at the last minute to have a C-section. She held out, resisted, and delivered a healthy baby vaginally.

For her second childbirth, she chose an accredited birth center that allowed her to have a doula and a midwife.

“The care I received was night and day,” she said. “The overwhelming pressure to consent to a C-section wasn’t there.”

She welcomes the information provided by the new U.S. News & World Report rankings as well as the upcoming “Birthing Friendly” designations.

“The onus shouldn’t be on patients, on individuals, on pregnant people to do the research,” Ms. Arnold said.

Rather, women and their partners need information at their fingertips so they can make an informed decision about how to give birth and where.

U.S. Rep. Lauren Underwood (D-Ill.), who cofounded the Black Maternal Health Caucus in April 2019, with Rep. Alma Adams (D-N.C.), wrote a touching blog in the journal Health Affairs to explain her passion in improving maternal health.

Her former classmate, Shalon Irving, who went on to become a CDC epidemiologist, died in February 2017 at age 36, just 3 weeks after giving birth, when she developed complications from high blood pressure.

In the blog, Ms. Underwood cited statistics and provides details of the Black Maternal Health Momnibus Act of 2021, then ends the blog, published in 2020, with an update on how Ms. Irving’s then 3-year-old daughter, raised by her grandmother, is doing. While Soleil is “curious, joyful, and brilliant,” the grandmother told Ms. Underwood that she has also walked into a room and found the little girl clutching a framed photograph of her mother.

The child’s question is understandable and heartbreaking: She wants to know where her mommy is.

“Soleil’s question is my motivation,” Ms. Underwood wrote. “To honor Shalon, and all the women like her who we have lost, let us take the serious and urgent action that is required to save our moms.”

In the United States, nearly 4 million women a year prepare to give birth, looking forward to the joy to come. But for some, the dream turns tragic. About 700 women die each year either during their pregnancy or in the weeks after the birth. And another 60,000 have pregnancy-related or childbirth-related health issues.

Causes of death vary greatly, including hemorrhage during pregnancy or during delivery, heart conditions, and mental health issues such as substance abuse and suicide after the birth.

In 2019, the U.S. maternal death rate was 20.1 per 100,000 women, according to the CDC, significantly higher than the 17.4 per 100,000 recorded in 2018. For Black women, the maternal death rate was more than double the overall – 44 per 100,000 in 2019.

“We have to address our horrendous maternal health care system and also need to address the inequities,” says Laurie Zephyrin, MD, vice president for advancing health equity for the Commonwealth Fund, a foundation supporting independent research on health care issues. “This is an issue that has needed national attention for a long time.”

“If we look overall, our maternal death rate is more than twice that of more than 10 other high-income countries,” she said.

As sobering as the problem is, recent developments have sparked hope that reversing the course is possible. Among them:

U.S. News & World Report, long known for its rankings of hospitals, issued its first ever “Best Hospitals for Maternity” rankings Dec. 7, highlighting facilities that perform well on key quality indicators. It plans to update the report annually.

At the first-ever White House Maternal Health Day of Action on Dec. 7, Vice President Kamala Harris urged a call to action to reduce maternal deaths and pregnancy-related health problems, with extension of postpartum coverage through Medicaid programs, among other actions.

A new hospital designation called ‘’Birthing Friendly” will be established by the Centers for Medicare & Medicaid Services. The label will be given to facilities that take part in a program aimed at improving maternal outcomes and that use patient safety practices.

President Joe Biden’s proposed Build Back Better plan includes maternal health provisions, including $3 billion in new maternal health funding. The money will aim to grow and diversify the workforce caring for pregnant women, coordinate care better, and step up research on maternal health, among other projects.

Ongoing efforts in Congress are aimed at fixing the wide disparities in maternal health affecting Black women. Regardless of income level or education, Black women are at a higher risk of maternal death and other health issues than are White women. A Black woman with a college education is at 60% higher risk of maternal death than a White or Hispanic woman who didn’t graduate high school, according to the Commonwealth Fund.

The cutoff for programmed death–ligand 1 (PD-L1) combined positive score (CPS) of at least 10 for using pembrolizumab (Keytruda) to treat metastatic triple-negative breast cancer (mTNBC) is able to identify patients who are expected to derive most benefit, shows an analysis of KEYNOTE-355 recently presented at the San Antonio Breast Cancer Symposium.

Patients enrolled in KEYNOTE-355 – which is a phase 3, placebo-controlled trial of 847 patients – were stratified by CPS scores of at least 1 and at least 10, with the latter group in which adding pembrolizumab to chemotherapy was shown to significantly improve both overall survival and progression-free survival.

As it was unclear whether taking a more fine-grained approach would reveal specific CPS scores at which pembrolizumab would be beneficial, Javier Cortes, MD, PhD, International Breast Cancer Center, Barcelona, and colleagues divided the patients into four CPS levels: less than 1, 1-9, 10-19, and at least 20.

Patients with a CPS 10-19 and at least 20 given pembrolizumab alongside chemotherapy had an overall survival benefit of 29% and 28%, respectively, while the PFS improvement was 30% and 38%. In the CPS of less than 1 and 1-9 groups, there were no discernible benefits from adding the checkpoint inhibitor.

“Given the similar outcomes in the CPS 10-19 and the CPS ≥20 subgroups, a CPS of 10 or more is a reasonable cutoff to define the population of patients with metastatic TNBC that might have benefit from the addition of pembrolizumab to chemotherapy,” Dr. Cortes said. “In my opinion, these results provide further support for pembrolizumab in combination with chemotherapy as a good option, maybe a standard of care for some patients ... with local recurrent unresectable or metastatic TNBC whose tumors express PD-1 CPS ≥10.”

Invited discussant Hope S. Rugo, MD, said the study demonstrates that PD-L1 CPS of at least 10 is “clearly the optimal cutoff for differentiating benefit from pembrolizumab” and confirms the combination with chemotherapy as a “standard of care in this population”.

However, there are a number of outstanding questions in the metastatic setting, she said, including the test used to determine PD-L1 expression.

“Clearly the test that you order should be matched to the planned checkpoint inhibitor, and we look forward to additional data” on the relative overlap of the assays used in both the current study and in KEYNOTE-522.

However, IMpassion130 showed there is “incomplete overlap in terms of the two antibodies and tests that have been used to define PD-L1 positivity in breast cancer,” said Dr. Rugo, professor of medicine in hematology and oncology at the University of California, San Francisco.

“For excellent responders, can chemotherapy and eventually immunotherapy be discontinued, and when is it optimal? How long should we be continuing the combination and how long should we continue the checkpoint inhibitor alone?” she asked.

“Certainly in my own clinical practice,” Dr. Rugo explained, “in those excellent responders, it’s difficult to know when to stop the checkpoint inhibitor, but sometimes toxicity tells us the answer to that question. At some point, we need to stop therapy and understand what happens to those patients.”

She said that only 38% of patients in the current study benefited from pembrolizumab. “How can we amplify the immune response in those patients who do not have PD-L1–positive disease to further extend this benefit, and can we extend the efficacy to other subtypes? There are ongoing studies evaluating this question,” Dr. Rugo said.

Dr. Cortes said that KEYNOTE-355 showed the addition of pembrolizumab to chemotherapy led to clinically meaningful improvements in both PFS and overall survival versus chemotherapy alone in the first-line treatment of mTNBC.

However, that benefit was seen only in patients with a PD-L1 CPS of at least 10, while there was no statistically significant improvement in either PFS or overall survival in those with a CPS of at least 1.

He explained that 847 patients with previously untreated locally recurrent or metastatic TNBC, or those who had been treated at least 6 months prior to disease recurrence, were randomized 2:1 to pembrolizumab or placebo plus chemotherapy.

For the current analysis, they substratified patients by PD-L1 CPS into less than 1, which accounted for 24.9% of patients; 1-9, seen in 36.2%-38.4%; 10-19, accounting for 13.9%-14.1%; and at least 20, seen in 22.8%-24.7% of patients.

Dr. Cortes said the overall survival rate among patients with CPS of at least 10 was 70.5% for patients treated with pembrolizumab plus chemotherapy versus 81.6% for those assigned to placebo, at a significant hazard ratio of 0.73 (P = .0093).

Among patients with CPS of at least 1, the overall survival rate was 79.1% with pembrolizumab plus chemotherapy and 83.9% in those given placebo, at a nonsignificant hazard ratio of 0.86. This translated into an HR of 0.89 in the intention-to-treat analysis.

Turning to the novel subgroups, Dr. Cortes showed that the HR for overall survival for pembrolizumab versus placebo was nonsignificant in patients with CPS of at least 1, at 0.97, and in those with CPS 1-9, at 1.09.

However, the HRs were markedly improved in patients with CPD 10-19, at 0.71, and in those with CPS of at least 20, at 0.72, showing that the “relative benefit of adding pembrolizumab to chemotherapy was pretty much the same ... suggesting that CPS ≥10 could be a reasonable cutoff.”

In both of these groups, there was a sustained separation in the overall survival curves starting at around 10 months.

Turning to the PFS results, Dr Cortes said the event-free rate was 65.5% with the addition of pembrolizumab to chemotherapy in patients with PD-L1 CPS of at least 10, while those given placebo had a rate of 78.6%, at an HR of 0.66.

In patients with PD-L1 CPS of at least 1, the HR was 0.75, or 0.82 in the intention-to-treat analysis.

“As with overall survival,” he said, there was a “trend toward improved efficacy with PD-L1 enrichment with the addition of pembrolizumab to chemotherapy, although the PFS benefit in the pembro arm was slightly greater in the CPS ≥20 subgroup, compared to the CPS 10-19 subgroup.”

However, they highlighted that the difference was “small and the confidence intervals clearly overlapped.”

Why does PD-L1 expression play a role in response to pembrolizumab in mTNBC, but not in the early disease setting as seen in KEYNOTE-522?

“This is a question we have raised many, many times and have had many debates on,” Dr. Cortes said. “They are two completely different populations with the early breast cancer setting completely different to that in metastatic disease. Maybe the microenvironment plays a different role there, maybe we have to explore more in detail other biomarkers. I also think that different drugs were used in the neoadjuvant setting. We still have many unanswered questions.”

Dr. Rugo suggested that previous studies have given some clues to these questions with reductions in PD-L1 expression and tumor-infiltrating leukocytes observed between primary and metastatic disease.

The immune differences between primary and metastatic disease lead to immune escape, she said, adding: “This is clearly complicated by mutational complexity under the pressure of treatment.”

The study was funded by Merck Sharp and Dohme. Dr. Cortes and Dr. Rugo reported relationships with numerous pharmaceutical companies.

She said that only 38% of patients in the current study benefited from pembrolizumab. “How can we amplify the immune response in those patients who do not have PD-L1–positive disease to further extend this benefit, and can we extend the efficacy to other subtypes? There are ongoing studies evaluating this question,” Dr. Rugo said.

Dr. Cortes said that KEYNOTE-355 showed the addition of pembrolizumab to chemotherapy led to clinically meaningful improvements in both PFS and overall survival versus chemotherapy alone in the first-line treatment of mTNBC.

However, that benefit was seen only in patients with a PD-L1 CPS of at least 10, while there was no statistically significant improvement in either PFS or overall survival in those with a CPS of at least 1.

He explained that 847 patients with previously untreated locally recurrent or metastatic TNBC, or those who had been treated at least 6 months prior to disease recurrence, were randomized 2:1 to pembrolizumab or placebo plus chemotherapy.

For the current analysis, they substratified patients by PD-L1 CPS into less than 1, which accounted for 24.9% of patients; 1-9, seen in 36.2%-38.4%; 10-19, accounting for 13.9%-14.1%; and at least 20, seen in 22.8%-24.7% of patients.

Dr. Cortes said the overall survival rate among patients with CPS of at least 10 was 70.5% for patients treated with pembrolizumab plus chemotherapy versus 81.6% for those assigned to placebo, at a significant hazard ratio of 0.73 (P = .0093).

Among patients with CPS of at least 1, the overall survival rate was 79.1% with pembrolizumab plus chemotherapy and 83.9% in those given placebo, at a nonsignificant hazard ratio of 0.86. This translated into an HR of 0.89 in the intention-to-treat analysis.

Turning to the novel subgroups, Dr. Cortes showed that the HR for overall survival for pembrolizumab versus placebo was nonsignificant in patients with CPS of at least 1, at 0.97, and in those with CPS 1-9, at 1.09.

However, the HRs were markedly improved in patients with CPD 10-19, at 0.71, and in those with CPS of at least 20, at 0.72, showing that the “relative benefit of adding pembrolizumab to chemotherapy was pretty much the same ... suggesting that CPS ≥10 could be a reasonable cutoff.”

In both of these groups, there was a sustained separation in the overall survival curves starting at around 10 months.

Turning to the PFS results, Dr Cortes said the event-free rate was 65.5% with the addition of pembrolizumab to chemotherapy in patients with PD-L1 CPS of at least 10, while those given placebo had a rate of 78.6%, at an HR of 0.66.

In patients with PD-L1 CPS of at least 1, the HR was 0.75, or 0.82 in the intention-to-treat analysis.

“As with overall survival,” he said, there was a “trend toward improved efficacy with PD-L1 enrichment with the addition of pembrolizumab to chemotherapy, although the PFS benefit in the pembro arm was slightly greater in the CPS ≥20 subgroup, compared to the CPS 10-19 subgroup.”

However, they highlighted that the difference was “small and the confidence intervals clearly overlapped.”

Why does PD-L1 expression play a role in response to pembrolizumab in mTNBC, but not in the early disease setting as seen in KEYNOTE-522?

“This is a question we have raised many, many times and have had many debates on,” Dr. Cortes said. “They are two completely different populations with the early breast cancer setting completely different to that in metastatic disease. Maybe the microenvironment plays a different role there, maybe we have to explore more in detail other biomarkers. I also think that different drugs were used in the neoadjuvant setting. We still have many unanswered questions.”

Dr. Rugo suggested that previous studies have given some clues to these questions with reductions in PD-L1 expression and tumor-infiltrating leukocytes observed between primary and metastatic disease.

The immune differences between primary and metastatic disease lead to immune escape, she said, adding: “This is clearly complicated by mutational complexity under the pressure of treatment.”

The study was funded by Merck Sharp and Dohme. Dr. Cortes and Dr. Rugo reported relationships with numerous pharmaceutical companies.

Tumor biology and socioeconomics only partly explain why acute lymphoblastic leukemia survival outcomes are worse for young Hispanic and Black patients than White patients, but they don’t explain it entirely, according to a report at the American Society of Hematology annual meeting.

Among almost 25,000 children and young adults up to 31 years old, all of whom participated in Children’s Oncology Group studies since 2004, 5-year event free survival (EFS) was 87.4% for White patients, 82.8% for Hispanic patients, and 81.9% for Black patients.

When socioeconomics and disease characteristics such as CNS involvement, white blood cell lineage, and induction status were taken into account, the risk of having a survival event fell from 37% to 11% higher for Hispanic patients versus White patients but from 45% to 32% for Black patients versus White patients.

However, there was no explicit adjustment in the study for acuity at presentation, body mass index, adherence to protocols, or Philadelphia chromosome (PH)-like disease, which is more common among Hispanic patients.

Even so, lead investigator Sumit Gupta, MD, a pediatric blood cancer specialist at the University of Toronto, said that even with the potential confounders, lingering differences in outcomes raise questions about equal access to care and other matters, and suggest that there are still “uncomfortable things to consider, things like ... structural racism” and a system that delivers “systemically different care to patients across racial” groups.

Another report presented at the meeting with 295 patients 18-40 years old found that Hispanic patients had 3-year overall survival comparable to that of White patients despite a higher prevalence of PH-like disease, perhaps because Hispanic patients had higher treatment adherence than did White patients at 76% versus 56%, said lead investigator Lori Muffly, MD, a bone and marrow transplant specialist at Stanford (Calif.) University.

However, Hispanic ALL patients were underrepresented in the study because the investigators didn’t recruit in Texas and Florida, states with higher percentages of young Hispanic ALL patients, and recruitment in California fell short of the prevalence of young Hispanic patients in that state. The work was a substudy of CALGB 10403, a trial of pediatric regimens in adolescents and young adults.

“It’s a relatively easy maneuver, going to where the patients are. When groups are thinking about multicenter trials, it has to be part of the dialogue from the beginning,” Dr. Muffly said.

Black patients in the review had fewer days in treatment and a higher prevalence of T-cell disease, and didn’t do as well as other groups.

Together, the studies “offer insight into the magnitude of racial and ethnic disparities in care among young people with” ALL, said Mikkael Sekeres, MD, chief of the division of hematology at the University of Miami, who moderated the presentations.

Dr. Gupta and his team found outcome differences only in relapsed B-cell ALL, not T-cell disease. B-cell disease has a more rigorous maintenance schedule, so it could be that there’s a difference in sticking to follow-up between various groups or less rigorous monitoring by pediatric oncologists in some groups, he said.

Dr. Gupta’s study was funded by the National Cancer Institute and others. Dr. Muffly didn’t report a funding source, but reported ties to Pfizer, Amgen, and other companies. Dr. Gupta is involved with Jazz Pharmaceuticals.

Tisagenlecleucel failed to outperform standard of care treatment when given as a second-line treatment for certain patients with relapsed/refractory aggressive non-Hodgkin lymphomas, according to results of a randomized, phase 3 trial.

The chimeric antigen receptor (CAR) T-cell therapy did not improve event-free survival (EFS) in this phase 3 BELINDA study, potentially because of study design decisions or imbalances in relevant patient characteristics, according to the study investigators.

Despite the negative result, insights from this study will inform the development of future clinical trials of CAR T-cell therapy, said BELINDA investigator Michael R. Bishop, MD, of the David and Etta Jonas Center for Cellular Therapy, University of Chicago.

Findings of BELINDA, presented at the annual meeting of the American Society of Hematology, stand in contrast to two other high-profile CAR T-cell therapy studies also presented at the meeting. Those other studies demonstrated significant improvements in EFS in the second-line treatment of large B-cell lymphomas.

“All of us are excited to see that the other two trials were positive, and we were hoping that ours would be as well, but there are significant differences in the trial design,” Dr. Bishop said in a press conference held at the ASH meeting.

Tisagenlecleucel (tisa-cel), an anti-CD19 CAR T-cell therapy, is already approved by the Food and Drug Administration for the treatment of patients with relapsed or refractory large B-cell lymphomas after at least two other lines of systemic therapy.

The aim of the pivotal phase 3, randomized, multicenter BELINDA study was to evaluate tisa-cel earlier in the course of treatment for patients with more aggressive disease, according to Dr. Bishop.

About two-thirds of non-Hodgkin lymphoma patients will be cured with first-line treatment. However, very poor outcomes are seen among patients with disease that does not respond to the initial treatment or that reoccurs shortly afterward, Dr. Bishop said.

The standard of care approach for those patients is second-line therapy, he noted, usually with combination chemoimmunotherapy, followed by autologous stem cell transplant if the disease responds to chemotherapy.

“Unfortunately, only a minority of those patients will be found to have chemotherapy-sensitive disease and be able to go on to autologous stem cell transplantation,” Dr. Bishop said. “And even in that subgroup of patients, the outcomes are relatively poor.”

Accordingly, the phase 3 BELINDA study enrolled patients with aggressive non-Hodgkin lymphomas that either did not respond to first-line treatment or that reoccurred within 12 months.

The primary endpoint of the study was EFS, defined as the time from randomization to either stable or progressive disease at or after a week 12 assessment or to any-cause death at any time.

While that primary endpoint was not met for tisa-cel versus standard of care therapy, two other randomized, phase 3 studies presented at the ASH meeting did demonstrate that CAR T-cell therapy extended EFS when given as a second-line lymphoma treatment.

In the randomized, phase 3 ZUMA-7 trial, axicabtagene ciloleucel (axi-cel) significantly improved EFS versus standard of care in the treatment of patients with large B-cell lymphoma refractory to or relapsed within 12 months of adequate first-line therapy, according to investigators.

Similarly, the investigators said that treatment with lisocabtagene maraleucel (liso-cel) led to a significant improvement in EFS in TRANSFORM, a randomized, phase 3 clinical trial that enrolled patients with large B-cell lymphoma that was refractory to first-line therapy or else relapsed within 12 months of that treatment.

“It’s very possible that either or both the patient characteristics and the study design is what led to the difference in the top-line study results,” lymphoma specialist Andrew M. Evens, DO, said in an interview.

There were substantial differences between the studies in terms of what was allowed as optional bridging therapy and salvage therapy, according to Dr. Evens, associate director for clinical services and director of the lymphoma program at Rutgers Cancer Institute in New Brunswick, N.J.

“In ZUMA-7, they only allowed steroids as bridging therapy,” said Dr. Evens, who was not an investigator on any of the three second-line CAR T-cell studies.

In the BELINDA study, optional platinum-based chemotherapy bridging treatment allowed in one arm of the study could have potentially delayed tisa-cel infusion until after the week 6 assessment, study investigators reported in their ASH meeting abstract.

Differences in lymphodepleting therapy prior to CAR T-cell therapy could have also played a role. According to Dr. Bishop, the total doses of cyclophosphamide and fludarabine in BELINDA were 900 mg/m2 and 75 mg/m2, respectively, while in the other two trials, doses were 1,500 mg/m² and 90 mg/m², respectively.

Lymphodepleting chemotherapy is “extremely important” in the success of CAR T-cell therapeutic approaches, he noted at the press conference.

Dr. Bishop reported receiving consultancy fees from Arcellx, Autolus Therapeutics, Bristol-Myers Squibb, CRISPR, Kite/Gilead, and Novartis. He also reported research funding from Bristol-Myers Squibb and Kite/Gilead.

ATLANTA – Older patients with acute lymphoblastic leukemia positive for the Philadelphia chromosome (Ph+ALL) are often not fit enough to withstand intensive chemotherapy and stem cell transplants, but remissions with alternative therapies are usually short lived.

Now, results from an ongoing study suggest that the combination of the tyrosine kinase inhibitor (TKI) dastatinib (Sprycel) with the bispecific T-cell engager (BiTE) blinatumomab (Blincyto), together with prednisone, may significantly improve remission rates and prolong both progression-free and overall survival among older and/or less fit patients with Ph+ALL.

The new results were reported by investigators in the SWOG Cancer Research Network and come from a cohort of 25 patients with a median age of 73 years with newly diagnosed Ph+ALL or ALL with dasatinib-sensitive fusions of mutations (Ph-like ALL).

Nearly all (23 of 25 patients, 92%) had complete remissions, and 5 of 16 patients for whom minimal residual disease (MRD) data were available were MRD negative at day 28, said Anjali Advani, MD, from the Cleveland Clinic.

At a median follow-up of 1.7 years, the estimated 3-year disease-free survival rate was 80%, and the estimated overall survival rate was 85%, the investigators reported in a poster presentation at the annual meeting of the American Society of Hematology.

“I think the biggest question will be longer-term follow-up. We clearly see high remission rates in this population, but the issue is whether in these elderly patients who are not candidates for chemo we can prolong remission by the addition of other treatments, such as blinatumomab,” she said in an interview with this news organization.

“The follow-up is reasonable at this point, and as we get longer follow-up, if the current 3-year survival estimates hold up, that would be very encouraging,” she said.
 

Early promise

A leukemia specialist who was not involved in the study told this news organization that the results are promising, but added that it’s too early to make definitive judgments about the efficacy of the combination.

“People have used just a tyrosine kinase inhibitor and prednisone in these patients and gotten remissions, but they just don’t last,” said Peter Emanuel, MD, from CHI St. Vincent Infirmary in Little Rock, Ark.

“The promise with this approach is that you’re getting a longer-lasting remission – maybe not a cure, but a longer-lasting remission – without having to use intensive chemotherapy,” he said.

“It’s still a pretty small study, so I think this is going to require a bigger trial, looking at more patients, but it’s certainly very encouraging and very promising,” he added.

Hanno Hock, MD, PhD, a leukemia researcher at the Mass General Cancer Center in Boston, said in an interview that “the whole idea here is to add this newer agent, blinatumomab, to make those good initial responses more durable, and it looks like it is able to do that with very impressive initial data,” he said.

“The caveat is that this is still early, and one needs to wait and see how it all pans out, but it’s very well tolerated, and definitely the next logical step in trying to offer something to people who cannot tolerate more aggressive therapy such as transplant,” Dr. Hock added.
 

Study results

The new results come from a feasibility cohort of patients enrolled in the SWOG S1318 trial, which studied blinatumomab plus chemotherapy and prednisone in older patients with Ph-ALL, as well as blinatumomab, dasatinib, and prednisone in older adults with Ph+ ALL.

Patients 65 and older with newly diagnosed or relapsed/refractory Ph+ALL or Ph-like ALL and no central nervous system disease were eligible for the arm of the trial described here. All patients with data reported in this analysis had newly diagnosed ALL.

Patients first received a single induction cycle of dasatinib and prednisone and were then evaluated for response. Patients with a complete remission (CR) or CR with incomplete recovery of blood counts (CRi) would then undergo prednisone tapering while continuing dasatinib until day 84. Patients without a CR or CRi at day 28 who had remissions by day 56 then also continued dasatinib until day 84.

Those patients still in remission at day 84 went on to three cycles of blinatumomab and dasatinib, followed by dasatinib and prednisone maintenance until unacceptable toxicity or disease progression. Patients may remain on maintenance for up to 10 years after registration.

Patients who do not have a CR or CRi by day 84 can receive reinduction with up to two total cycles of blinatumomab, with those who get a remission moving on to the blinatumomab/ dasatinib combination and those who do not going off protocol.

Of the 25 patients, 23 had a CR following dasatinib/prednisone induction. As noted, 5 of 16 patients evaluable for MRD were MRD negative.

Four patients did not receive postremission therapy, two because of adverse events, one who went on to transplant, and one because of insurance issues.

In a safety review early in the study, 4 of 12 evaluable patients were found to have dose-limiting toxicities, including one case each of grade 3 dyspnea and gastrointestinal pain (in a single patient), hypertension, dyspnea, and hyperglycemia.

These adverse events were deemed acceptable by both U.S. Food and Drug Administration and National Cancer Institute reviewers, and this arm of the study was allowed to continue, Dr. Advani noted.

The study was funded by grants from the National Institutes of Health. Dr. Advani disclosed financial relationships with several companies. Dr. Emanuel and Dr. Hock have disclosed no relevant financial relationships.

ATLANTA – Older patients with acute lymphoblastic leukemia positive for the Philadelphia chromosome (Ph+ALL) are often not fit enough to withstand intensive chemotherapy and stem cell transplants, but remissions with alternative therapies are usually short lived.

Now, results from an ongoing study suggest that the combination of the tyrosine kinase inhibitor (TKI) dastatinib (Sprycel) with the bispecific T-cell engager (BiTE) blinatumomab (Blincyto), together with prednisone, may significantly improve remission rates and prolong both progression-free and overall survival among older and/or less fit patients with Ph+ALL.

The new results were reported by investigators in the SWOG Cancer Research Network and come from a cohort of 25 patients with a median age of 73 years with newly diagnosed Ph+ALL or ALL with dasatinib-sensitive fusions of mutations (Ph-like ALL).

Nearly all (23 of 25 patients, 92%) had complete remissions, and 5 of 16 patients for whom minimal residual disease (MRD) data were available were MRD negative at day 28, said Anjali Advani, MD, from the Cleveland Clinic.

At a median follow-up of 1.7 years, the estimated 3-year disease-free survival rate was 80%, and the estimated overall survival rate was 85%, the investigators reported in a poster presentation at the annual meeting of the American Society of Hematology.

“I think the biggest question will be longer-term follow-up. We clearly see high remission rates in this population, but the issue is whether in these elderly patients who are not candidates for chemo we can prolong remission by the addition of other treatments, such as blinatumomab,” she said in an interview with this news organization.

“The follow-up is reasonable at this point, and as we get longer follow-up, if the current 3-year survival estimates hold up, that would be very encouraging,” she said.
 

Early promise

A leukemia specialist who was not involved in the study told this news organization that the results are promising, but added that it’s too early to make definitive judgments about the efficacy of the combination.

“People have used just a tyrosine kinase inhibitor and prednisone in these patients and gotten remissions, but they just don’t last,” said Peter Emanuel, MD, from CHI St. Vincent Infirmary in Little Rock, Ark.

“The promise with this approach is that you’re getting a longer-lasting remission – maybe not a cure, but a longer-lasting remission – without having to use intensive chemotherapy,” he said.

“It’s still a pretty small study, so I think this is going to require a bigger trial, looking at more patients, but it’s certainly very encouraging and very promising,” he added.

Hanno Hock, MD, PhD, a leukemia researcher at the Mass General Cancer Center in Boston, said in an interview that “the whole idea here is to add this newer agent, blinatumomab, to make those good initial responses more durable, and it looks like it is able to do that with very impressive initial data,” he said.

“The caveat is that this is still early, and one needs to wait and see how it all pans out, but it’s very well tolerated, and definitely the next logical step in trying to offer something to people who cannot tolerate more aggressive therapy such as transplant,” Dr. Hock added.
 

Study results

The new results come from a feasibility cohort of patients enrolled in the SWOG S1318 trial, which studied blinatumomab plus chemotherapy and prednisone in older patients with Ph-ALL, as well as blinatumomab, dasatinib, and prednisone in older adults with Ph+ ALL.

Patients 65 and older with newly diagnosed or relapsed/refractory Ph+ALL or Ph-like ALL and no central nervous system disease were eligible for the arm of the trial described here. All patients with data reported in this analysis had newly diagnosed ALL.

Patients first received a single induction cycle of dasatinib and prednisone and were then evaluated for response. Patients with a complete remission (CR) or CR with incomplete recovery of blood counts (CRi) would then undergo prednisone tapering while continuing dasatinib until day 84. Patients without a CR or CRi at day 28 who had remissions by day 56 then also continued dasatinib until day 84.

Those patients still in remission at day 84 went on to three cycles of blinatumomab and dasatinib, followed by dasatinib and prednisone maintenance until unacceptable toxicity or disease progression. Patients may remain on maintenance for up to 10 years after registration.

Patients who do not have a CR or CRi by day 84 can receive reinduction with up to two total cycles of blinatumomab, with those who get a remission moving on to the blinatumomab/ dasatinib combination and those who do not going off protocol.

Pheochromocytoma is a rare catecholamine-secreting tumor of chromaffin cells of the adrenal medulla or sympathetic ganglia, occurring in about 0.2 to 0.5% of patients with hypertension.^1-3 However, in a review of 54 autopsy-proven cases of pheochromocytoma, about 50% of the patients with hypertension were not clinically suspected for pheochromocytoma.⁴

Pheochromocytoma is usually diagnosed based on symptoms of hyperadrenergic spells, resistant hypertension, especially in the young, with a pressor response to the anesthesia stress test and adrenal incidentaloma.

The classic triad of symptoms associated with pheochromocytoma includes episodic headache (90%), sweating (60-70%), and palpitations (70%).^2,5 Sustained or paroxysmal hypertension is the most common symptom reported in about 95% of patients with pheochromocytoma. Other symptoms include pallor, tremors, dyspnea, generalized weakness, orthostatic hypotension, cardiomyopathy, or hyperglycemia.⁶ However, about 10% of patients with pheochromocytoma are asymptomatic or mildly symptomatic.⁷ Secondary causes of hypertension are usually suspected in multidrug resistant or sudden early onset of hypertension.⁸

Approximately 10% of catecholamine-secreting tumors are malignant.^9-11 Benign and malignant pheochromocytoma have a similar biochemical and histologic presentation and are differentiated based on local invasion into the surrounding tissues and organs (eg, kidney, liver) or distant metastasis.

A high index of suspicion is necessary during the workup of secondary hypertension as untreated pheochromocytoma may lead to significant morbidity and mortality, especially in patients who require surgical treatment.^4,12 Multiple cases of hypertensive crisis, pulmonary edema, cardiac arrhythmia, and cardiogenic shock are reported in undiagnosed patients with pheochromocytoma undergoing both adrenal or nonadrenal surgery who were not medically prepared with α- and β-adrenergic antagonists and fluids before surgery.^13,14

A typical workup of a suspected patient with pheochromocytoma includes biochemical tests, including measurements of urinary and fractionated plasma metanephrines and catecholamine. Patients with positive biochemical tests should undergo localization of the tumor with an imaging study either with an adrenal/abdominal magnetic resonance imaging (MRI) or computed tomography (CT) scan. If a patient has paraganglioma or an adrenal mass > 10 cm or negative abdominal imaging with a positive biochemical test, further imaging with an iobenguane I-123 scan is needed (Figure 1).

Case Presentation

A 72-year-old male with a medical history of diabetes, hypertension, sensory neuropathy, benign prostatic hypertrophy (BPH) status posttransurethral resection of the prostate, and chronic renal failure presented to establish care with the Arizona Kidney Disease and Hypertension Center. His medications included losartan 50 mg by mouth daily, diltiazem 180 mg extended-release by mouth daily, carvedilol 6.25 mg by mouth twice a day, and tamsulosin 0.4 mg by mouth daily. His presenting vitals were blood pressure (BP), 112/74 left arm sitting, pulse, 63/beats per min, and body mass index, 34. On physical examination, the patient was alert and oriented, and the chest was clear to auscultation without wheeze or rhonchi. On cardiac examination, heart rate and rhythm were regular; S1 and S2 were normal with no added murmurs, rubs or gallops, and no jugular venous distension. The abdomen was soft, nontender, with no palpable mass. His laboratory results showed sodium, 142 mmol/L; potassium, 5.3 mmol/L; chloride, 101 mmol/L; carbon dioxide, 24 mmol/L; albumin, 4.3 g/dL; creatinine, 1.89 mg/dL; blood urea nitrogen, 29 mg/dL; estimated glomerular filtration rate non-African American, 35 mL/min/1.73; 24-h urine creatinine clearance, 105 mL/min; protein, 1306 mg/24 h (Table).

His renal ultrasound showed an exophytic isoechoic mass or complex cyst at the lateral aspect of the lower pole of the right kidney, measuring 45 mm in diameter. An MRI of the abdomen with and without contrast showed a solid partially exophytic mass of the posterolateral interpolar cortex of the right kidney, measuring 5.9 cm in the greatest dimension (Figure 2). No definite involvement of Gerota fascia was noted, a 1-cm metastasis to the right adrenal gland was present, renal veins were patent, and there was no upper retroperitoneal lymphadenopathy.

Treatment and Follow-up

The patient underwent right-hand-assisted lap-aroscopic radical nephrectomy and right adre-nalectomy without any complications. However, the surgical pathology report showed oncocytoma of the kidney (5.7 cm), pheochromocytoma of the adrenal gland (1.4 cm), and papillary adenoma of the kidney (0.7 cm). Right kidney nephrectomy showed non-neoplastic renal parenchyma, diabetic glomerulosclerosis (Renal Pathology Society 2010 diabetic nephropathy class IIb), severe mesangial expansion, moderate interstitial fibrosis, moderate arteriosclerosis, and mild arteriolosclerosis.

A fluorodeoxyglucose-positron emission tomography (FDG-PET) scan was significant for right nephrectomy and adrenalectomy and showed no significant evidence of residual neoplasm or local or distant metastases. A nuclear medicine (iobenguane I-123) tumor and single positron emission computed tomography (SPECT) scan showed normal activity throughout the body and no evidence of abnormal activity (Figure 3).

Discussion

Pheochromocytoma is a rare cause of secondary hypertension. However, the real numbers are thought to be > 0.2 to 0.5%.^1,2,4 Patients with pheochromocytoma should undergo surgical adrenal resection after appropriate medical preparation. Patients with pheochromocytoma who are not diagnosed preoperatively have increased surgical mortality rates due to fatal hypertensive crises, malignant arrhythmia, and multiorgan failure as a result of hypertensive crisis.¹⁵ Anesthetic drugs during surgery also can exacerbate the cardiotoxic effects of catecholamines. Short-acting anesthetic agents, such as fentanyl, are used in patients with pheochromocytoma.¹⁶

This case of pheochromocytoma illustrated no classic symptoms of episodic headache, sweating, and tachycardia, and the patient was otherwise asymptomatic. BP was well controlled with losartan, diltiazem, and a β-blocker with α-blocking activity (carvedilol). As the patient was not known to have pheochromocytoma, he did not undergo preoperative medical therapy. Figure 4 illustrates the receptors stimulate catecholamines, and the drugs blocking these receptors prevent hypertensive crisis during surgery. However, the surgery was without potential complications (ie, hypertensive crisis, malignant arrhythmia, or multiorgan failure). The patient was diagnosed incidentally on histopathology after right radical nephrectomy and adrenalectomy due to solid partially exophytic right renal mass (5.9 cm) with right adrenal metastasis. About 10% of patients are asymptomatic or mildly symptomatic.⁷ Sometimes, the symptoms may be ignored because of the episodic nature. Other possible reasons can be small, nonfunctional tumors or the use of antihypertensive medications suppressing the symptoms.⁷

The adrenal mass that was initially thought to be a metastasis of right kidney mass was later confirmed as pheochromocytoma. One possible explanation for uneventful surgery could be the use of β-blocker with α-blocking activity (carvedilol), α-1 adrenergic blocker (tamsulosin) along with nondihydropyridine calcium channel blocker (diltiazem) as part of the patient’s antihypertensive and BPH medication regimen. Another possible explanation could be silent or episodically secreting pheochromocytoma with a small functional portion.

Conclusions

Asymptomatic pheochromocytoma is an unusual but serious condition, especially for patients undergoing a surgical procedure. An adrenal mass may be ignored in asymptomatic or mildly symptomatic older adult patients and is mostly considered as adrenal metastasis when present with other malignancies. Fortunately, the nephrectomy and adrenalectomy in our case of asymptomatic pheochromocytoma was uneventful, but pheochromocytoma should be ruled out before a surgical procedure, as an absence of medical pretreatment can lead to serious consequences. Therefore, we suggest a more careful screening of pheochromocytoma in patients with an adrenal mass (primary or metastatic) and hypertension treated with multiple antihypertensive drugs, even in older adult patients.
