Dr Jack West, from City of Hope Comprehensive Cancer Center, Duarte, California, gives his picks of noteworthy advances in non–small cell lung cancer (NSCLC) presented at the 37th Annual Meeting of the Society for Immunotherapy of Cancer. 

Dr West starts by discussing data from a real-world analysis of patients who had undergone next-generation sequencing and received a variety of treatments. This revealed that those with KRAS mutations, alongside STK11 and KEAP1 mutations, had worse outcomes. 

Next, he reports on a genomic study indicating that acquired resistance mechanisms affecting a range of genes were unique to immunotherapy and were not seen with chemotherapy or targeted therapies. 

Dr West moves on to KEYNOTE-495, which found that NSCLC patients with a favorable gene expression profile and low tumor mutational burden had the greatest response to combination therapy with pembrolizumab and lenvatinib. 

The LAG-3 inhibitor eftilagimod alpha in combination with pembrolizumab was examined in the next study, which showed that PD-L1 expression was related to response rates. 

Dr West closes by discussing a talk that made the case for neoadjuvant over adjuvant immunotherapy in lung cancer and other settings.

Heather Meador and Anna Herber-Downey use dating apps on the job – and their boss knows it.

Both are public health nurses employed by Linn County Public Health in eastern Iowa. They’ve learned that dating apps are the most efficient way to inform users that people they previously met on the sites may have exposed them to sexually transmitted infections.

A nationwide surge in STIs, also known as STDs – with reported cases of gonorrhea and syphilis increasing 10% and 7%, respectively, from 2019 to 2020, according to the Centers for Disease Control and Prevention – isn’t sparing Iowa. The duo has found that the telephone call, a traditional method of contact tracing, no longer works well.

“When I started 12 years ago, we called everyone,” said Ms. Meador, the county health department’s clinical branch supervisor. “It’s getting harder and harder to just call someone on the phone.”

Even texting is ineffective, they said. And people aren’t necessarily answering messages on Facebook. The dating apps are where they’re at.

Because many people are meeting sex partners online – via sites like Grindr or Snapchat, which are headquartered in West Hollywood and Santa Monica, Calif., respectively – contact tracers often don’t have much information to go on, just a screen name or a picture.

So, about a year ago, Ms. Meador and her colleagues got approval from their bosses at the local level to build profiles on the app, through which they can contact the sex partners of infected people.

Traditionally, contact tracers interview people infected with an STI about their recent encounters and then reach out to those partners to tell them about the potential exposure.

Linn County contact tracers use the apps throughout their workday. Grindr, in particular, relies on geolocation, showing users matches who are close by. So the tracers use the apps when they’re out and about, hoping to wander into the same neighborhoods as the person diagnosed with an STI. Sometimes users “tap” the contract tracers to see whether they’re interested – in dating, that is.

When the public health officials spot someone they’re looking for, they send a message asking for a call. It’s a successful method: Ms. Herber-Downey estimated they make an initial contact 75% of the time.

Linn County’s decision to move online comes as STI rates rise nationally, funding to fight them falls, and people adopt new technologies to meet people and seek fun. “STIs are increasing way faster than the funding we have,” said Leo Parker, director of prevention programs for the National Coalition of STD Directors, all while public health departments – many underfunded – are grappling with new behaviors.

“Social media companies have billions; we have tens of thousands,” said Jeffrey Klausner, MD, MPH, a University of Southern California, Los Angeles, public health professor, who previously served as San Francisco’s director of STD prevention and control services. That funding disparity means few public health departments have staff members who can go online. “It’s only really in major cities that they have anyone who’s tasked for that,” Dr. Klausner said.

Even when departments have enough employees to take on the challenge, institutional support can be lacking. Some public health officials question employees who log into the apps. Dr. Klausner once testified on behalf of a Ventura County, Calif., contact tracer who was fired for using sex sites for work.

But with people migrating online to meet partners, following them there makes sense. “We’re now in a digital age,” Mr. Parker said. Individuals might not be out, or might be questioning their identity, making online venues comfortable, anonymous spaces for romance – which, in turn, means people are harder to reach face-to-face, at least at first.

What’s more, online spaces like Grindr are effective public health tools beyond contact tracing. They can be useful ways to get the word out about public health concerns.

Mr. Parker and the Linn County officials said public service announcements on dating apps – advocating for condom use or sharing the business hours for sexual health clinics – do seem to lead people to services. “We do have individuals coming in, saying, ‘I saw you had free testing. I saw it on Grindr,’ ” Mr. Parker said.

Grindr, which touts itself as the biggest dating app focused on LGBTQ+ people, pushes out messages and information to its members, said Jack Harrison-Quintana, director of Grindr for Equality. That engagement intensified during a 2015 meningitis outbreak among LGBTQ+ communities in Chicago, for example.

During that outbreak, the app sent citywide messages about vaccination. Then Mr. Harrison-Quintana took advantage of the service’s design: Using the site’s geolocating capabilities, Grindr workers targeted messages to specific neighborhoods. “We could go in and really go block to block and say, ‘Is this where the cases are showing up?’ ” he said. If so, they sent more messages to that area.

That campaign encouraged further efforts from the app, which regularly sends public health messages about everything from COVID-19 to monkeypox to the platform’s base of roughly 11 million monthly users. Grindr also allows users to display their HIV status and indicate whether they’re vaccinated against COVID, monkeypox, and meningitis.

There are a couple of things Grindr won’t do, however. The company won’t allow public health departments to create institutional accounts. And it won’t allow automated notifications about STI exposures to be sent to users.

That’s due to privacy concerns, the company said, despite calls from public health advocates to deploy better messaging features. Grindr believes that a government presence on the app would be too intrusive and that even anonymous notifications would allow users to trace infections back to their source. (When asked about public health officials who join the site on their own, company spokesperson Patrick Lenihan said: “Individuals are free to say something like ‘I’m a public health professional – ask me about my work!’ in their profile and are free to discuss sexual and public health matters however they see fit.”)

Grindr’s position – however disappointing to some in the public health world – reflects a longtime balancing act attempted by the private sector, which aims to square government concerns with users’ privacy interests.

Dr. Klausner pointed to a 1999 syphilis outbreak in San Francisco as one of the first times he saw how those interests could be at odds. The outbreak was traced to an AOL chatroom. Based on his research, Dr. Klausner said it seemed as though people could go online and “get a sex partner faster than you can get a pizza delivered.”

But persuading New York–based Time Warner, eventually AOL’s corporate parent, to cooperate was time-intensive and tricky – gaining entrée into the chatroom required help from the New York attorney general’s office.

The online industry has advanced since then, Dr. Klausner said. He helped one service develop a system to send digital postcards to potentially exposed people. “Congratulations, you got syphilis,” the postcards read. “They were edgy postcards,” he said, although some options were less “snarky.”

Overall, however, the dating app world is still “bifurcated,” he said. For public health efforts, apps that appeal to LGBTQ+ users are generally more helpful than those that predominantly cater to heterosexual clients.

That’s due to the community’s history with sexual health, explained Jen Hecht, a leader of Building Healthy Online Communities, a public health group partnering with dating apps. “Folks in the queer community have – what – 30, 40 years of thinking about HIV?” she said.

Even though STIs affect everyone, “the norm and the expectation is not there” for straight-focused dating apps, she said. Indeed, neither Match Group nor Bumble – the corporations with the biggest apps focused on heterosexual dating, both based in Texas – responded to multiple requests for comment from KHN.

But users, at least so far, seem to appreciate the app-based interventions. Mr. Harrison-Quintana said Grindr has landed on a just-the-facts approach to conveying health information. He has never received any backlash, “which has been very nice.”

As fentanyl-related overdose deaths continue to increase, clinicians should take note of important differences that set the drug apart from the other drugs of misuse – and the troubling reality that fentanyl now contaminates most of them.

“It would be fair to tell patients, if you’re buying any illicit drugs – pills, powder, liquid, whatever it is, you’ve got to assume it’s either contaminated with or replaced by fentanyl,” said Edwin Salsitz, MD, an associate clinical professor at the Icahn School of Medicine at Mount Sinai, New York, during a presentation on the subject at the 21st Annual Psychopharmacology Update presented by Current Psychiatry and the American Academy of Clinical Psychiatrists.

In many if not most cases, he noted, patients become addicted to fentanyl unknowingly. They assume they are ingesting oxycodone, cocaine, or another drug, and have no realization that they are even exposed to fentanyl until they test positive for it – or overdose.

Meanwhile, the high potency of fentanyl can overcome the opioid blockade of addiction treatment therapies – methadone and buprenorphine – that take away the high that users get from less potent drugs such as heroin.

“Fentanyl is overcoming this blockade that methadone and buprenorphine used to provide,” Dr. Salsitz said. “With fentanyl having such a higher potency, patients are saying ‘no, I still feel the fentanyl effects,’ and they continue feeling it even with 200 milligrams of methadone or 24 milligrams of buprenorphine.”
 

‘Wooden chest syndrome’

Among the lesser-known dangers of fentanyl is the possibility that some overdose deaths may occur as the result of a syndrome previously reported as a rare complication following the medical use of fentanyl in critically ill patients – fentanyl-induced chest-wall rigidity, or “wooden chest syndrome,” Dr. Salsitz explained.

In such cases, the muscles of respiration become rigid and paralyzed, causing suffocation within a matter of minutes – too soon to benefit from the overdose rescue medication naloxone.

In one recent study published in Clinical Toxicology , nearly half of fentanyl overdose deaths were found to have occurred even before the body had a chance to produce norfentanyl, a metabolite of fentanyl that takes only about 2-3 minutes to appear in the system, suggesting the deaths occurred rapidly.

In the study of 48 fentanyl deaths, no appreciable concentrations of norfentanyl could be detected in 20 of the 48 overdose deaths (42%), and concentrations were less than 1 ng/mL in 25 cases (52%).

“The lack of any measurable norfentanyl in half of our cases suggests a very rapid death, consistent with acute chest rigidity,” the authors reported.

“In several cases fentanyl concentrations were strikingly high (22 ng/mL and 20 ng/mL) with no norfentanyl detected,” they said.

Dr. Salsitz noted that the syndrome is not well known among the addiction treatment community.

“This is different than the usual respiratory opioid overdose where there’s a gradual decrease in the breathing rate and a gradual decrease in how much air is going in and out of the lungs,” Dr. Salsitz explained.

“With those cases, some may survive for an hour or longer, allowing time for someone to administer naloxone or to get the patient to the emergency room,” he said. “But with this, breathing stops and people can die within minutes.

“I think that this is one of the reasons that fentanyl deaths keep going up despite more and more naloxone availability out there,” he said.
 

Clearance may take longer

In toxicology testing for fentanyl, clinicians should also note the important difference between fentanyl and other opioids – that fentanyl, because of its high lipophilicity, may be detected in urine toxicology testing up to 3 weeks after last use. This is much longer than the 2- to 4-day clearance observed with other opioids, possibly causing patients to continue to test positive for the drug weeks after cessation.

This effect was observed in one recent study of 12 opioid use disorder patients in a residential treatment program who had previously been exposed to daily fentanyl.

The study showed the mean amount of time of fentanyl clearance was 2 weeks, with a range of 4-26 days after last use.

The authors pointed out that the findings “might explain recent reports of difficulty in buprenorphine inductions for persons who use fentanyl, and point to a need to better understand the pharmacokinetics of fentanyl in the context of opioid withdrawal in persons who regularly use fentanyl.”

Though the study was small, Dr. Salsitz said “that’s not a stumbling block to the important finding that, with regular use of fentanyl, the drug may stay in the urine for a long time.”

Dr. Salsitz noted that similar observations have been made at his center, with clinicians logically assuming that patients were still somehow getting fentanyl.

“When we initially found this in patients, we thought that they were using on the unit, perhaps that they brought in the fentanyl, because otherwise how could it stay in the urine that long,” he noted. “But fentanyl appears to be more lipophilic and gets into the fat; it’s then excreted very slowly and then stays in the urine.”

Dr. Salsitz said most practitioners think of fentanyl as a short-acting drug, so “it’s important to realize that people may continue to test positive and it should be thought of as a long-acting opioid.”
 

Opiate screening tests don’t work

Dr. Salsitz warned of another misconception in fentanyl testing – the common mistake of assuming that fentanyl should show up in a test for opiates – when in fact fentanyl is not, technically, an opiate.

“The word opiate only refers to morphine, codeine, heroin and sometimes hydrocodone,” he explained. “Other opioids are classified as semisynthetic, such as oxycodone, or synthetics, such as fentanyl and methadone, buprenorphine.”

“In order to detect the synthetics, you must have a separate strip for each one of those drugs. They will not show up positive on a screen for opiates,” he noted.

The belief that fentanyl and other synthetic and semisynthetic opioids will show positive on an opiate screen is a common misconception, he said. “The misunderstanding in toxicology interpretation is a problem for many practitioners, [but] it’s essential to understand because otherwise false assumptions about the patient will be considered.”

Another important testing misreading can occur with the antidepressant drug trazodone, which Dr. Salsitz cautioned may falsely test as positive for fentanyl on immunoassays.

“Trazodone is very commonly used in addiction treatment centers, but it can give a false positive on the fentanyl immunoassay and we’ve had a number of those cases,” he said.

Dr. Salsitz had no disclosures to report.

As fentanyl-related overdose deaths continue to increase, clinicians should take note of important differences that set the drug apart from the other drugs of misuse – and the troubling reality that fentanyl now contaminates most of them.

“It would be fair to tell patients, if you’re buying any illicit drugs – pills, powder, liquid, whatever it is, you’ve got to assume it’s either contaminated with or replaced by fentanyl,” said Edwin Salsitz, MD, an associate clinical professor at the Icahn School of Medicine at Mount Sinai, New York, during a presentation on the subject at the 21st Annual Psychopharmacology Update presented by Current Psychiatry and the American Academy of Clinical Psychiatrists.

In many if not most cases, he noted, patients become addicted to fentanyl unknowingly. They assume they are ingesting oxycodone, cocaine, or another drug, and have no realization that they are even exposed to fentanyl until they test positive for it – or overdose.

Meanwhile, the high potency of fentanyl can overcome the opioid blockade of addiction treatment therapies – methadone and buprenorphine – that take away the high that users get from less potent drugs such as heroin.

“Fentanyl is overcoming this blockade that methadone and buprenorphine used to provide,” Dr. Salsitz said. “With fentanyl having such a higher potency, patients are saying ‘no, I still feel the fentanyl effects,’ and they continue feeling it even with 200 milligrams of methadone or 24 milligrams of buprenorphine.”
 

‘Wooden chest syndrome’

Among the lesser-known dangers of fentanyl is the possibility that some overdose deaths may occur as the result of a syndrome previously reported as a rare complication following the medical use of fentanyl in critically ill patients – fentanyl-induced chest-wall rigidity, or “wooden chest syndrome,” Dr. Salsitz explained.

In such cases, the muscles of respiration become rigid and paralyzed, causing suffocation within a matter of minutes – too soon to benefit from the overdose rescue medication naloxone.

In one recent study published in Clinical Toxicology , nearly half of fentanyl overdose deaths were found to have occurred even before the body had a chance to produce norfentanyl, a metabolite of fentanyl that takes only about 2-3 minutes to appear in the system, suggesting the deaths occurred rapidly.

In the study of 48 fentanyl deaths, no appreciable concentrations of norfentanyl could be detected in 20 of the 48 overdose deaths (42%), and concentrations were less than 1 ng/mL in 25 cases (52%).

“The lack of any measurable norfentanyl in half of our cases suggests a very rapid death, consistent with acute chest rigidity,” the authors reported.

“In several cases fentanyl concentrations were strikingly high (22 ng/mL and 20 ng/mL) with no norfentanyl detected,” they said.

Dr. Salsitz noted that the syndrome is not well known among the addiction treatment community.

“This is different than the usual respiratory opioid overdose where there’s a gradual decrease in the breathing rate and a gradual decrease in how much air is going in and out of the lungs,” Dr. Salsitz explained.

“With those cases, some may survive for an hour or longer, allowing time for someone to administer naloxone or to get the patient to the emergency room,” he said. “But with this, breathing stops and people can die within minutes.

“I think that this is one of the reasons that fentanyl deaths keep going up despite more and more naloxone availability out there,” he said.
 

Clearance may take longer

In toxicology testing for fentanyl, clinicians should also note the important difference between fentanyl and other opioids – that fentanyl, because of its high lipophilicity, may be detected in urine toxicology testing up to 3 weeks after last use. This is much longer than the 2- to 4-day clearance observed with other opioids, possibly causing patients to continue to test positive for the drug weeks after cessation.

This effect was observed in one recent study of 12 opioid use disorder patients in a residential treatment program who had previously been exposed to daily fentanyl.

The study showed the mean amount of time of fentanyl clearance was 2 weeks, with a range of 4-26 days after last use.

The authors pointed out that the findings “might explain recent reports of difficulty in buprenorphine inductions for persons who use fentanyl, and point to a need to better understand the pharmacokinetics of fentanyl in the context of opioid withdrawal in persons who regularly use fentanyl.”

Though the study was small, Dr. Salsitz said “that’s not a stumbling block to the important finding that, with regular use of fentanyl, the drug may stay in the urine for a long time.”

Dr. Salsitz noted that similar observations have been made at his center, with clinicians logically assuming that patients were still somehow getting fentanyl.

“When we initially found this in patients, we thought that they were using on the unit, perhaps that they brought in the fentanyl, because otherwise how could it stay in the urine that long,” he noted. “But fentanyl appears to be more lipophilic and gets into the fat; it’s then excreted very slowly and then stays in the urine.”

Dr. Salsitz said most practitioners think of fentanyl as a short-acting drug, so “it’s important to realize that people may continue to test positive and it should be thought of as a long-acting opioid.”
 

Opiate screening tests don’t work

Dr. Salsitz warned of another misconception in fentanyl testing – the common mistake of assuming that fentanyl should show up in a test for opiates – when in fact fentanyl is not, technically, an opiate.

“The word opiate only refers to morphine, codeine, heroin and sometimes hydrocodone,” he explained. “Other opioids are classified as semisynthetic, such as oxycodone, or synthetics, such as fentanyl and methadone, buprenorphine.”

“In order to detect the synthetics, you must have a separate strip for each one of those drugs. They will not show up positive on a screen for opiates,” he noted.

The belief that fentanyl and other synthetic and semisynthetic opioids will show positive on an opiate screen is a common misconception, he said. “The misunderstanding in toxicology interpretation is a problem for many practitioners, [but] it’s essential to understand because otherwise false assumptions about the patient will be considered.”

Another important testing misreading can occur with the antidepressant drug trazodone, which Dr. Salsitz cautioned may falsely test as positive for fentanyl on immunoassays.

Nearly two-thirds of patients with advanced non–small cell lung cancer (NSCLC) who are eligible for targeted therapy are not receiving these drugs because of gaps in clinical practice all along the cancer care spectrum, reveals a new analysis of data from U.S. practices.

For some of these patients, it could mean missing the chance for long-term survival or even cure.

One lung cancer patient, Janet Freeman-Daily, recently tweeted that she entered a targeted therapy clinical trial 10 years ago and is still taking the same, now approved, oral drug, with “no evidence of disease.”

Patients who have lung cancer with mutations that can be targeted with drug therapies – but who do not receive them – are missing this opportunity.

The new study suggests that there are many such patients. The researchers analyzed data on more than 38,000 patients with actively managed advanced NSCLC. They found that about half did not receive biomarker test results for a variety of reasons. But even among the half who were successfully tested, 30% of these patients did not receive the appropriate targeted therapies.

Overall, around 64% of eligible patients with advanced NSCLC are not benefiting from the most appropriate therapies, the team concludes.

The research was published online in JCO Precision Oncology.
 

Gaps in clinical practice

The high rate of failure points to clinical practice gaps in “many areas” across the cancer care spectrum, lead author Daryl Pritchard, PhD, from the Personalized Medicine Coalition, Washington, told this news organization.

“There’s various steps along the way that affect clinicians, laboratories, payers, the health providers [and] even patients,” he said. He added that product manufacturers also “have a role.”

“So it’s not an individual group that’s causing the problem. It’s a systemic awareness and systemic need to improve the delivery process.”

Dr. Pritchard underlined that the “the main goal of this analysis is to put everybody on alert that we need to do something about it.

“We need to – and this is easy to say but hard to do – evolve health care from a traditional one-size-fits-all mentality to a value-based strategy where you’re saying we want the best treatments” for patients, he said.

This means developing optimized and standardized laboratory processes, as well as clinical guidelines that set out the standard of care and optimized and integrated clinical decision support.

“We need to work as a community to demonstrate the value of this care and improve education and awareness to providers and payers,” Dr. Pritchard said. “That will encourage value-based practice coverage and reimbursement policies, and then also incentivize utilization in validated cases.”

Julie R. Brahmer, MD, who directs the thoracic oncology program at Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins, Baltimore, Maryland, who was not involved with the study, said she was not sure whether she would say she was “surprised or disheartened” by the findings.

The study was focused on advanced NSCLC patients treated in 2019. Dr. Brahmer wondered whether the COVID-19 pandemic “might actually have made things worse.”

It will be important to “drill down” into some of the reasons why 30% of patients for whom biomarker testing results were available did not receive the appropriate treatment, she said.

Aside from cost-related problems, one factor at play could be whether the patient saw an oncologist, she said, while another could be that they went “straight to hospice” and were “not healthy enough to be able to tolerate” their targeted therapy.

Greater use of liquid biopsies, which identify biomarkers in the blood, are one way to improve access to biomarker testing, she suggested. It would help if these liquid biopsies were “consistently paid for by the payer, particularly for patients with advanced disease,” she added. Currently, payers often want patients to first undergo a tissue biopsy, which involves lung aspiration and may not be possible for some patients.

“If a Medicare patient is in the hospital when they have their biopsy or surgery, and then they have to wait 14 days in order for mutation tests to be ordered, and then if you add another 2 weeks for that test to come back, or even longer … [These delays] are some of the reasons why patients didn’t end up receiving therapy,” she elaborated.

“Some of these patients just can’t last that long before starting treatment,” she said.

Sandip P. Patel, MD, an oncologist at the Precision Immunotherapy Clinic at the University of California, San Diego, in La Jolla, wondered whether the issue is lack of education among physicians or whether there are potential financial problems. “Is there a financial risk to patients, for example, that is not being captured?” he mused.

It could also be a question of urban vs. rural centers, language barriers in communicating to patients, or other social determinants of health, he added.

At his institution (UCSD), there are “multiple choices” of molecular tests, each with “little nuances that differ among the tests that folks sometimes will take a look at in term of picking the best.

“But the best test is the one that gets done, and here we’re seeing no testing at all” for many patients, he said.

“It’s really unfortunate because for a lot of these patients, not only are they not getting the latest therapy, but they’re often getting something else that’s expensive and toxic instead,” Dr. Patel said.

Referring to the relatively high proportion of patients who didn’t receive targeted therapy even after being tested, he said, “For me, this study leaves more questions and answers.

“We’ve seen a lot of work in this space, showing us the problem,” Dr. Patel said. “What I haven’t yet seen is a very discrete analysis of the cause of that problem upstream.”
 

Cornerstone of personalized medicine

In their article, Dr. Pritchard and colleagues note that more than 90 targeted therapies have been approved by the U.S. Food and Drug Administration for use in eligible cancer patients. An estimated 55% of recent oncology trials involved the use of biomarkers.

Predictive biomarker testing to identify patients who may benefit from targeted therapies “is a cornerstone of personalized medicine in cancer care, allowing for more rapid diagnosis while informing treatment decisions that could lead to better patient outcomes and systemic efficiencies,” they emphasize.

However, providers “face several challenges” when integrating biomarker testing and targeted therapeutics into cancer care, and the use of biomarker testing varies widely across tumor types, biomarkers, and practice settings.

For their study, the team examined the use of targeted therapy in advanced NSCLC using data from the Diaceutics Data Repository, which includes commercial and Medicare claims, as well as laboratory data.

They focused on 38,068 patients with actively managed advanced NSCLC. Of those patients, 50.80% were women, and 64.6% were aged 71 years or older. The vast majority (84.50%) were non-Hispanic White patients.

The team examined the impact of seven clinical practice gaps on the timeline from ordering a biopsy to delivering targeted treatment. They then normalized the results to a standard patient population of 1,000.

In 6.6% of cases, an initial tissue or liquid biopsy was never performed, meaning that 66 of the 1,000 patients could not progress toward targeted therapy.

Among those who underwent a biopsy, for 4.0%, there was insufficient tissue on the initial biopsy, while for a further 0.97%, there was insufficient tissue on re-biopsy. Moreover, 9.6% could not undergo biopsy testing because of a lack of tumor tissue. Consequently, a further 136 of the 944 remaining patients were lost.

For the third clinical practice gap, the tumor cell content was overestimated in 1.7% of patients. As a result, their biopsy specimen could not be tested because it did not meet the threshold requirements. This resulted in the loss of a further 14 patients.

Moreover, for a further 17.5% of patients, biomarker testing was not ordered at all, owing to cost concerns, a lack of access to testing, a lack of awareness of testing options, and low confidence in the results, among other reasons. An additional 0.6% began treatment before any testing was ordered; together, that accounted for 142 patients being lost.

Even among patients who underwent biomarker testing, 14.5% had uninformative or inconclusive results, and 3.9% had false-negative results, meaning that a further 118 patients were lost.

In another 4.0% of cases, the results of biomarker testing did not arrive within the treatment decision window, owing to delays in reporting the results, and so for these patients, treatment began without the results being taken into consideration. A further 21 patients were lost.

The final clinical practice gap was not choosing the appropriate targeted treatment on the basis of test results. The researchers found that of 27,186 patients who underwent biomarker testing and received a timely result, 29.2% were not given the corresponding therapy. This resulted in the loss of a further 147 of the original 1,000 patients.

Overall, the team calculated that 64.4% of patients newly diagnosed with advanced NSCLC “are not benefiting from precision oncology care options appropriate for their diseases and will likely have suboptimal outcomes.”

The research was supported in part by the Personalized Medicine Coalition, a nonprofit 501c3 organization dedicated to the advancement of personalized medicine. Dr. Pritchard is an employee of the Personalized Medicine Coalition. A coauthor has relationships with Thermo Fisher Scientific, AstraZeneca, Eli Lilly, Blueprint Medicines, and Oncocyte.

Julie R. Brahmer, MD, who directs the thoracic oncology program at Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins, Baltimore, Maryland, who was not involved with the study, said she was not sure whether she would say she was “surprised or disheartened” by the findings.

The study was focused on advanced NSCLC patients treated in 2019. Dr. Brahmer wondered whether the COVID-19 pandemic “might actually have made things worse.”

It will be important to “drill down” into some of the reasons why 30% of patients for whom biomarker testing results were available did not receive the appropriate treatment, she said.

Aside from cost-related problems, one factor at play could be whether the patient saw an oncologist, she said, while another could be that they went “straight to hospice” and were “not healthy enough to be able to tolerate” their targeted therapy.

Greater use of liquid biopsies, which identify biomarkers in the blood, are one way to improve access to biomarker testing, she suggested. It would help if these liquid biopsies were “consistently paid for by the payer, particularly for patients with advanced disease,” she added. Currently, payers often want patients to first undergo a tissue biopsy, which involves lung aspiration and may not be possible for some patients.

“If a Medicare patient is in the hospital when they have their biopsy or surgery, and then they have to wait 14 days in order for mutation tests to be ordered, and then if you add another 2 weeks for that test to come back, or even longer … [These delays] are some of the reasons why patients didn’t end up receiving therapy,” she elaborated.

“Some of these patients just can’t last that long before starting treatment,” she said.

Sandip P. Patel, MD, an oncologist at the Precision Immunotherapy Clinic at the University of California, San Diego, in La Jolla, wondered whether the issue is lack of education among physicians or whether there are potential financial problems. “Is there a financial risk to patients, for example, that is not being captured?” he mused.

It could also be a question of urban vs. rural centers, language barriers in communicating to patients, or other social determinants of health, he added.

At his institution (UCSD), there are “multiple choices” of molecular tests, each with “little nuances that differ among the tests that folks sometimes will take a look at in term of picking the best.

“But the best test is the one that gets done, and here we’re seeing no testing at all” for many patients, he said.

“It’s really unfortunate because for a lot of these patients, not only are they not getting the latest therapy, but they’re often getting something else that’s expensive and toxic instead,” Dr. Patel said.

Referring to the relatively high proportion of patients who didn’t receive targeted therapy even after being tested, he said, “For me, this study leaves more questions and answers.

“We’ve seen a lot of work in this space, showing us the problem,” Dr. Patel said. “What I haven’t yet seen is a very discrete analysis of the cause of that problem upstream.”
 

Cornerstone of personalized medicine

In their article, Dr. Pritchard and colleagues note that more than 90 targeted therapies have been approved by the U.S. Food and Drug Administration for use in eligible cancer patients. An estimated 55% of recent oncology trials involved the use of biomarkers.

Predictive biomarker testing to identify patients who may benefit from targeted therapies “is a cornerstone of personalized medicine in cancer care, allowing for more rapid diagnosis while informing treatment decisions that could lead to better patient outcomes and systemic efficiencies,” they emphasize.

However, providers “face several challenges” when integrating biomarker testing and targeted therapeutics into cancer care, and the use of biomarker testing varies widely across tumor types, biomarkers, and practice settings.

For their study, the team examined the use of targeted therapy in advanced NSCLC using data from the Diaceutics Data Repository, which includes commercial and Medicare claims, as well as laboratory data.

They focused on 38,068 patients with actively managed advanced NSCLC. Of those patients, 50.80% were women, and 64.6% were aged 71 years or older. The vast majority (84.50%) were non-Hispanic White patients.

The team examined the impact of seven clinical practice gaps on the timeline from ordering a biopsy to delivering targeted treatment. They then normalized the results to a standard patient population of 1,000.

In 6.6% of cases, an initial tissue or liquid biopsy was never performed, meaning that 66 of the 1,000 patients could not progress toward targeted therapy.

Among those who underwent a biopsy, for 4.0%, there was insufficient tissue on the initial biopsy, while for a further 0.97%, there was insufficient tissue on re-biopsy. Moreover, 9.6% could not undergo biopsy testing because of a lack of tumor tissue. Consequently, a further 136 of the 944 remaining patients were lost.

For the third clinical practice gap, the tumor cell content was overestimated in 1.7% of patients. As a result, their biopsy specimen could not be tested because it did not meet the threshold requirements. This resulted in the loss of a further 14 patients.

Moreover, for a further 17.5% of patients, biomarker testing was not ordered at all, owing to cost concerns, a lack of access to testing, a lack of awareness of testing options, and low confidence in the results, among other reasons. An additional 0.6% began treatment before any testing was ordered; together, that accounted for 142 patients being lost.

Even among patients who underwent biomarker testing, 14.5% had uninformative or inconclusive results, and 3.9% had false-negative results, meaning that a further 118 patients were lost.

In another 4.0% of cases, the results of biomarker testing did not arrive within the treatment decision window, owing to delays in reporting the results, and so for these patients, treatment began without the results being taken into consideration. A further 21 patients were lost.

The final clinical practice gap was not choosing the appropriate targeted treatment on the basis of test results. The researchers found that of 27,186 patients who underwent biomarker testing and received a timely result, 29.2% were not given the corresponding therapy. This resulted in the loss of a further 147 of the original 1,000 patients.

Overall, the team calculated that 64.4% of patients newly diagnosed with advanced NSCLC “are not benefiting from precision oncology care options appropriate for their diseases and will likely have suboptimal outcomes.”

The research was supported in part by the Personalized Medicine Coalition, a nonprofit 501c3 organization dedicated to the advancement of personalized medicine. Dr. Pritchard is an employee of the Personalized Medicine Coalition. A coauthor has relationships with Thermo Fisher Scientific, AstraZeneca, Eli Lilly, Blueprint Medicines, and Oncocyte.

The Food and Drug Administration is moving to further restrict the use of certain PARP inhibitors in patients with ovarian cancer, citing recent data showing an increased risk for death with the agents versus chemotherapy.

These restrictions could mean bankruptcy for one company.

Earlier this year, several companies voluntarily withdrew their respective PARP inhibitors for heavily pretreated patients with ovarian cancer in later-line indications.

Now, the FDA has asked GlaxoSmithKline and Clovis Oncology to restrict the second-line indications for their PARP inhibitors – niraparib (Zejula) for GSK and rucaparib (Rubraca) for Clovis.

The FDA’s requests are based on recent data showing an increased risk for death with the PARP inhibitors versus chemotherapy.

On Nov. 11, GSK announced that, at the FDA’s request, it will limit the second-line maintenance indication for its PARP inhibitor niraparib to patients with deleterious or suspected deleterious germline BRCA mutations.

The prescribing change was based on an FDA review of the final overall survival analysis of the NOVA phase 3 trial, which served as the basis for the approval of the second-line maintenance indication. The final overall survival data showed a hazard ratio of 1.06 (95% confidence interval, 0.81-1.37) in the cohort without germline BRCA mutations.

The company noted, however, that its first-line indication remains unchanged.

The FDA has also asked Clovis Oncology to restrict its PARP inhibitor rucaparib in the second-line maintenance therapy setting, according to a Nov. 14 U.S. Securities and Exchange Commission filing from the company. Rucaparib is currently not approved to treat ovarian cancer in the first-line setting.

According to the filing, the FDA met with Clovis Oncology to discuss the overall survival data from the ARIEL3 clinical trial, which formed the basis for the drug’s approval in the United States as second-line maintenance for adult patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who had a complete or partial response to platinum-based chemotherapy.

In September 2022, Clovis Oncology submitted the final overall survival data from the ARIEL3 trial to FDA. According to the company, among all populations analyzed, the confidence intervals for all hazard ratios crossed 1, “indicating no difference between the treatment arms.”

Based on the overall survival data, the FDA requested that Clovis “voluntarily revise the label to limit the indication of Rubraca in this second-line maintenance treatment” to only patients with BRCA mutations.

Clovis said it is “currently evaluating FDA’s request.” If an agreement can’t be reached, the FDA said it would convene an advisory committee to review the matter.

However, further restricting the indication for rucaparib could put the company’s future in jeopardy. In an earlier report, Clovis Oncology foreshadowed a “potential bankruptcy filing in the very near term” as “increasingly probable.”

The company explained that, because “a substantial portion” of the drug’s revenue is attributable to its second-line indication, limiting that indication “could result in a significant impact on our revenue.”

The report continued: “Based on our current cash and cash equivalents, together with current estimates for revenues to be generated by sales of Rubraca, we will not have sufficient liquidity to maintain our operations beyond January 2023.”

Reporting on highlights in axial spondyloarthritis (AxSpA) from the American College of Rheumatology Convergence 2022, Dr Philip Mease of Swedish Medical Center in Seattle calls attention to studies on promising therapeutic outcomes. 

He begins with the late-breaking long-range therapeutic results of bimekizumab, which was shown to be effective in patients with nonradiographic AxSpA and those with ankylosing spondylitis over 52 weeks. 

Next, he reports on a study examining withdrawal vs tapering of golimumab, which underscored the benefit of tapering in prevention of disease flares. 

Dr Mease then discusses a study in which cycling between tumor necrosis factor inhibitors provided disappointing results in the AxSpA population, suggesting that switching to a therapy with a different mechanism of action might achieve better outcomes. 

Another study cited by Dr Mease explored the use of combination therapy in patients with AxSpA, which yielded promising results. Should this approach take hold, Dr Mease says that in the future, "we'll be more like oncologists, mixing and matching and doing what's best for our patients to bring them into a state of remission." 

Dr Mease closes by discussing a large study investigating COVID among patients with autoimmune diseases, including AxSpA and psoriasis. The study found that neither the conditions themselves nor their treatments significantly increased risk for severe outcomes.

With recent expansions in its breast cancer indications, there has been an increase in the use of trastuzumab deruxtecan (T-DXd; Enhertu).

“A lot of us are using this more frequently now than we were in the past,” explained Sid Yadav, MD, a breast and gynecologic cancer specialist at the Mayo Clinic in Rochester, Minn. However, he added that managing its adverse events has been a “bit of a learning curve for all of us.”

The antibody-drug conjugate has been on the market since 2019 for metastatic human epidermal growth factor receptor (HER2)–positive breast cancer, but it was then approved in May 2022 for earlier use in this patient population and in August 2022 for patients with HER2-low disease. This latest approval was based on data showing an improvement in overall survival that was described as “practice changing.”

In addition, T-DXd is also approved for use in metastatic HER2-mutated non–small cell lung cancer and metastatic HER2-positive gastric and gastroesophageal junction adenocarcinoma.

Expanding use of this drug has led to growing awareness among oncologists of T-DXd’s considerable toxicities, Dr. Yadav told this news organization.

Among the eight or so patients he’s seen or treated over 2 months, Dr. Yadav has already seen one case of high-grade interstitial lung disease/pneumonitis, a complication that “everybody worries about” because the label for T-DXd carries a black box warning of this possibility.

There have been other issues at Mayo Clinic, as well. In one recent week, five patients were admitted for possible T-DXd adverse events, including neutropenic fever and sepsis; pneumonitis; severe nausea/vomiting with electrolyte imbalance; pneumonia, and non–ST elevation myocardial infarction with low ejection fraction.

It’s unknown what proportion of T-DXd recipients the five admissions represented. Dr. Yadav’s service has over 10 breast oncologists, so the cases could represent maybe 1%-10% of patients, he said.

His experience prompted Dr. Yadav to turn to Twitter to ask fellow oncologists what complications they’ve seen with T-DXd.

One said that his “real-world toxicity experience [has been] worse than the trial data,” which isn’t unusual, another oncologist noted, because real-world patients are often sicker than trial participants and more vulnerable to toxicities.

A third oncologist countered that she has “found [T-DXd] generally easy for patients to tolerate and [has] not needed to admit anyone” so far.

Overall, Dr. Yadav said that in his experience there are issues that need to be considered with T-DXd beyond interstitial lung disease.

As with any chemotherapy, neutropenia and infections are a concern, as the labeling notes. The interstitial lung disease case has also made Dr. Yadav have a low threshold to order CT in patients with any hints of shortness of breath and to start steroids if there’s any suspicion.

Probably the most common issue, however, is nausea and vomiting. In clinical trials, over 70% of participants reported nausea and over 40% experienced vomiting.

In response, Dr. Yadav and his colleagues have become more aggressive with prophylaxis. Pretreatment includes steroids, palonosetron, and fosaprepitant. Patients are also usually sent home with prochlorperazine, ondansetron, and lorazepam. If these don’t help, the team considers olanzapine.

They have also learned that “it’s important to spend that extra 15-20 minutes upfront” with patients before starting T-DXd to explain the risk for nausea and vomiting and how it will be managed, Dr. Yadav commented. “We do chemotherapy teaching for every patient, but I think we spend more time [now] talking about nausea and vomiting with this subset,” he said.

Dr. Yadav still starts patients on the standard breast cancer dose of T-DXd – 5.4 mg/kg every 3 weeks – but said he’s quicker now to lower the dose if patients aren’t doing well. He estimates he’s done that a couple of times so far.

Approaches at the Mayo Clinic are in line with those in a recent article on managing T-DXd toxicities by Hope Rugo, MD, from the University of California, San Francisco, and colleagues.

These authors conclude that adverse events related to T-DXd are frequent but are most commonly low grade and manageable. Nausea and vomiting are among the most common, and they note that interstitial lung disease/pneumonitis is an important adverse event, for which proactive monitoring, diagnosis, and management are key.

The review describes management practices of other health care providers and institutions with experience in using T-DXd to help with safe and effective management of the drug’s adverse events, particularly since the duration of treatment may be quite long.

Proper management of T-DXd–related adverse events will allow optimal exposure to and benefit from the drug and will help avoid premature discontinuation or improper dose reductions, Dr. Rugo and colleagues commented.

Dr. Yadav reports no relevant conflicts of interest.

Among the eight or so patients he’s seen or treated over 2 months, Dr. Yadav has already seen one case of high-grade interstitial lung disease/pneumonitis, a complication that “everybody worries about” because the label for T-DXd carries a black box warning of this possibility.

There have been other issues at Mayo Clinic, as well. In one recent week, five patients were admitted for possible T-DXd adverse events, including neutropenic fever and sepsis; pneumonitis; severe nausea/vomiting with electrolyte imbalance; pneumonia, and non–ST elevation myocardial infarction with low ejection fraction.

It’s unknown what proportion of T-DXd recipients the five admissions represented. Dr. Yadav’s service has over 10 breast oncologists, so the cases could represent maybe 1%-10% of patients, he said.

His experience prompted Dr. Yadav to turn to Twitter to ask fellow oncologists what complications they’ve seen with T-DXd.

One said that his “real-world toxicity experience [has been] worse than the trial data,” which isn’t unusual, another oncologist noted, because real-world patients are often sicker than trial participants and more vulnerable to toxicities.

A third oncologist countered that she has “found [T-DXd] generally easy for patients to tolerate and [has] not needed to admit anyone” so far.

Overall, Dr. Yadav said that in his experience there are issues that need to be considered with T-DXd beyond interstitial lung disease.

As with any chemotherapy, neutropenia and infections are a concern, as the labeling notes. The interstitial lung disease case has also made Dr. Yadav have a low threshold to order CT in patients with any hints of shortness of breath and to start steroids if there’s any suspicion.

Probably the most common issue, however, is nausea and vomiting. In clinical trials, over 70% of participants reported nausea and over 40% experienced vomiting.

In response, Dr. Yadav and his colleagues have become more aggressive with prophylaxis. Pretreatment includes steroids, palonosetron, and fosaprepitant. Patients are also usually sent home with prochlorperazine, ondansetron, and lorazepam. If these don’t help, the team considers olanzapine.

They have also learned that “it’s important to spend that extra 15-20 minutes upfront” with patients before starting T-DXd to explain the risk for nausea and vomiting and how it will be managed, Dr. Yadav commented. “We do chemotherapy teaching for every patient, but I think we spend more time [now] talking about nausea and vomiting with this subset,” he said.

Dr. Yadav still starts patients on the standard breast cancer dose of T-DXd – 5.4 mg/kg every 3 weeks – but said he’s quicker now to lower the dose if patients aren’t doing well. He estimates he’s done that a couple of times so far.

Approaches at the Mayo Clinic are in line with those in a recent article on managing T-DXd toxicities by Hope Rugo, MD, from the University of California, San Francisco, and colleagues.

These authors conclude that adverse events related to T-DXd are frequent but are most commonly low grade and manageable. Nausea and vomiting are among the most common, and they note that interstitial lung disease/pneumonitis is an important adverse event, for which proactive monitoring, diagnosis, and management are key.

The review describes management practices of other health care providers and institutions with experience in using T-DXd to help with safe and effective management of the drug’s adverse events, particularly since the duration of treatment may be quite long.

Proper management of T-DXd–related adverse events will allow optimal exposure to and benefit from the drug and will help avoid premature discontinuation or improper dose reductions, Dr. Rugo and colleagues commented.

Dr. Yadav reports no relevant conflicts of interest.

If there’s one public health message Americans have heard loud and clear, it’s this one:

Move more.

Take more steps.

Spend more time doing physical activity – at least 150 minutes a week, according to the latest guidelines.

But hearing the message doesn’t mean we act on it. A whopping 25% of Americans don’t get any physical activity beyond what they do in their job, according to a CDC survey.

A new study suggests a different approach: You don’t have to do more. Just do what you’re already doing, but with a little more effort.

The study, which was published in the European Heart Journal, builds on growing evidence that suggests exercise intensity matters just as much as the amount. So, something as simple as turning a leisurely stroll into a brisk walk can, over time, lead to significant reductions in your risk of cardiovascular disease. No additional moves, steps, or minutes needed.
 

Step it up

Researchers at Cambridge University and the University of Leicester in England looked at data from 88,000 middle-aged adults who wore an activity tracking device for 7 days.

The devices tracked both the total amount of activity they did and the intensity of that movement – that is, how fast they walked or how hard they pushed themselves.

The researchers then calculated their physical activity energy expenditure (the number of calories they burned when they were up and moving) and the percentage that came from moderate to vigorous physical activity.

What’s the difference?

• Physical activity means any and every movement you do throughout the day. Mostly it’s mundane tasks like shopping, walking to the mailbox, playing with your dog, or cooking.
• Moderate-intensity physical activity includes things you do at a faster pace. Maybe you’re walking for exercise, doing yard work or household chores, or running late and just trying to get somewhere faster. You’re breathing a little harder and possibly working up a sweat.
• Vigorous-intensity physical activity is usually an exercise session – a run, a strenuous hike, a tough workout in the gym. It can also be an exhausting chore like shoveling snow, which feels like a workout. You’re definitely breathing harder, and you’re probably working up a sweat, even in the middle of winter.

Over the next 6 to 7 years, there were 4,000 new cases of cardiovascular disease among the people in the study.

Those who got at least 20% of their physical activity energy expenditure from moderate to vigorous activities had significantly less risk of heart disease, compared with those whose higher-effort activities were about 10%.

That was true even for those whose total activity was relatively low. As long as higher-effort activities reached 20% of their total, they were 14% less likely to be diagnosed with a heart condition.

And for those with relatively high activity levels, there was little extra benefit if their moderate and vigorous activities remained around 10%.

That finding surprised Paddy Dempsey, PhD, a medical research scientist at Cambridge and the study’s lead author. But it also makes sense.

“People can improve their cardiorespiratory fitness to a greater degree with higher-intensity activity,” he says. “More intensity will stress the system and lead to greater adaptation.”

The key is an increase in the amount of oxygen your heart and lungs can provide your muscles during exercise, a measure known as VO_2max.

Raising your VO_2max is the best way to reduce your risk of early death, especially death from heart disease. Simply moving up from the lowest conditioning category to a higher one will cut your risk of dying in any given year by as much as 60%.
 

Making strides

The study builds on previous research that shows the benefits of moving faster.

Walking faster will naturally increase your stride length, another predictor of longevity and future health. A review study published in 2021 found that older adults who took shorter steps were 26% more likely to have a disability, 34% more likely to have a major adverse event (like an injury that leads to a loss of independence), and 69% more likely to die over the next several years.
 

Quality versus quantity

We’ve focused so far on the quality of your physical activity – moving faster, taking longer strides.

But there’s still a lot to be said for movement quantity.

“It would be a mistake to say volume doesn’t matter,” Dr. Dempsey cautions.

A 2022 study in the journal The Lancet found that the risk of dying during a given period decreases with each increase in daily steps. The protective effect peaks at about 6,000 to 8,000 steps a day for adults 60 and over, and at 8,000 to 10,000 steps for those under 60.

“The relative value of the quality and quantity of exercise are very specific to a person’s goals,” says Chhanda Dutta, PhD, chief of the Clinical Gerontology Branch at the National Institute on Aging. “If performance is the goal, quality matters at least as much as quantity.”

Dr. Dempsey agrees that it’s not a cage match between two. Every step you take is a step in the right direction.

“People can choose or gravitate to an approach that works best for them,” he says. “It’s also helpful to think about where some everyday activities can be punctuated with intensity,” which could be as simple as walking faster when possible.

What matters most is that you choose something, Dr. Dutta says. “You have more to risk by not exercising.”

The Food and Drug Administration has announced it will not approve the investigational drug poziotinib (Spectrum Pharmaceuticals) for the treatment of certain patients with non–small cell lung cancer (NSCLC).

The clinical data the company submitted were deemed insufficient for approval, and additional data including a randomized clinical trial would be needed, the agency said.

The move is not a surprise, as the FDA’s Oncologic Drugs Advisory Committee (ODAC) voted 9-4 against approval when it met to discuss the drug in September, as reported at the time by this news organization.

Poziotinib was developed for patients with previously treated locally advanced or metastatic NSCLC harboring HER2 exon 20 insertion mutations, which occur in about 2% of patients with NSCLC.

Poziotinib is a potent oral pan-HER tyrosine kinase inhibitor with activity in patients with these mutations. Clinical data from the ZENITH20 Trial reported last year showed an overall response rate of 43.8%, and the drug was described as showing “clinically meaningful efficacy for treatment-naive NSCLC HER2 exon 20 mutations with [daily] dosing.”

“We continue to believe that poziotinib could present a meaningful treatment option for patients with this rare form of lung cancer, for whom other therapies have failed,” commented Tom Riga, president and chief executive officer of Spectrum Pharmaceuticals. 

However, following multiple interactions with the FDA, “we have made the strategic decision to immediately deprioritize the poziotinib program,” he said. The change is effective immediately, and the company is now in the process of reducing its R&D workforce by approximately 75%.
 

Drug development criticized

At the ODAC meeting, several panelists were openly critical of the approach Spectrum took in developing the drug. The FDA’s top cancer official, Richard Pazdur, MD, characterized Spectrum’s work as “poor drug development” and likened it to “building a house on quicksand.”

The FDA panel detailed several ways they felt that the poziotinib application fell short of the benchmarks needed for accelerated approval.

To win such a speedy clearance, a company needs to show that a drug provides a meaningful therapeutic benefit over existing treatments. The panel argued that, so far, poziotinib appears to be inferior to a product already available for HER2-mutant NSCLC, trastuzumab deruxtecan (Enhertu), which received accelerated approval in August.

The FDA staff contrasted a reported overall response rate for poziotinib, which was estimated at 28% (from data discussed at the meeting), with the overall response rate for trastuzumab deruxtecan, which is 58%.

Harpreet Singh, MD, a director in the FDA’s oncology division, asked the panel to consider what they would do as a physician treating a patient with this mutation, given the choices that are now available.

“That’s something we’re asking the committee to consider … to think about the context of what’s available to you in the clinic,” Dr. Singh said.

Dr. Singh said she expected that patients and physicians would prefer a drug such as trastuzumab deruxtecan, which has a more established record, regardless of the fact that treatment with poziotinib is more convenient because it is given as a tablet.

Dr. Singh and other staff also raised concerns about side effects of poziotinib, including diarrhea, as well as difficulty determining the right dose.

Katherine Scilla, MD, one of the nine ODAC panelists to vote “no,” echoed these views. Although Dr. Scilla, an oncologist at the University of Maryland, Baltimore, sympathized with the need for options for people with this rare form of lung cancer, she was not persuaded by the data on poziotinib that were presented to support accelerated approval.

“I’m not sure that this represents a meaningful therapeutic benefit over other agents,” she said at the time.

CHICAGO – Discovering lung cancer early with annual low-dose computed tomography greatly improves long-term survival rates to 80%, findings from a 20-year international study indicate.

Claudia Henschke, MD, PhD, professor of radiology and director of the Early Lung and Cardiac Action Program at the Icahn School of Medicine at Mount Sinai, New York, presented research results at the annual meeting of the Radiological Society of North America.

The researchers studied lung-cancer–specific survival (LCS) of 87,416 participants enrolled in an international, prospective study named the International Early Lung Cancer Action Program.

Lung cancer is the leading cause of cancer death. The American Lung Association states the average 5-year survival rate is 18.6%. Only 16% of the cancers are caught early and more than half of people with lung cancer die within a year of diagnosis.
 

Participants’ 20-year survival rate 80%

Results of this large international study showed the overall 20-year survival rate for the 1,285 screening participants diagnosed with early-stage cancer was 80% (95% confidence interval, 77%-83%). Among the 1,285 diagnosed, 83% had stage 1 cancer, Dr. Henschke said.

Lung cancer survival (LCS) was 100% for the 139 participants with nonsolid nodule consistency and for the 155 participants with part-solid consistency. LCS was 73% (95% CI, 69%-77%) for the 991 with solid consistency, and for clinical stage IA participants LCS was 86% (95% CI, 83%-89%), regardless of consistency.

For participants with pathologic stage IA lung cancer 10 mm or less in average diameter, the 20-year survival rate with identification and resection was 92% (95% CI, 87%-96%).

No lung cancer deaths were identified in the part-solid and nonsolid cancers, the researchers report.

These results show the 10-year findings from 2006 published in the New England Journal of Medicine, which also showed 80% survival rates with low-dose CT, have persisted, she said.

At the time of the 2006 paper, 95% of Americans diagnosed with lung cancer died from it, Dr. Henschke said.

Dr. Henschke notes that by the time symptoms appear, lung cancer is often advanced, so the best tool for detecting early-stage lung cancer is enrolling in an annual screening program.

When cancer is small enough and can be surgically removed, patients can be effectively cured long-term, she said.

“In the future, perhaps blood markers will allow us to detect it in the first half of the life cycle of lung cancer instead of CT at the beginning of the second half of the life cycle,” Dr. Henschke said.

“The study raises the power of prospective data collection in the context of clinical care as recommended by the Institute of Medicine long ago,” she said.
 

Findings “very promising”

Ernest Hawk, MD, MPH, head of the division of cancer prevention and population sciences at the University of Texas MD Anderson Cancer, Houston, told this news organization the findings look “very promising.” Dr. Hawk was not involved in the study.

“This was one of the earliest studies to evaluate low-dose CT scanning. Their report that the initial benefits seem to be holding up over a longer period of observation is great,” he said.

“This bolsters the data that lung cancer screening is beneficial over a longer period of observation,” he said, noting that most of the randomized controlled trials have been shorter.

Lung cancer screening is now recommended for high-risk individuals – those with at least a 20-pack-year history of tobacco use who are between 50 and 80 years old.

So far, screening is still limited to people at high risk, Dr. Hawk said, though there’s discussion about whether benefit would extend to people exposed to asbestos, for instance, or secondhand smoke.

“The biggest challenge right now is getting the screening to those who actually meet the criteria,” Dr. Hawk said.

Medscape reported earlier this month that less than 6% of high-risk smokers have the recommended annual lung cancer screening, according to a new report from the American Lung Association.

CHICAGO – Discovering lung cancer early with annual low-dose computed tomography greatly improves long-term survival rates to 80%, findings from a 20-year international study indicate.

Claudia Henschke, MD, PhD, professor of radiology and director of the Early Lung and Cardiac Action Program at the Icahn School of Medicine at Mount Sinai, New York, presented research results at the annual meeting of the Radiological Society of North America.

The researchers studied lung-cancer–specific survival (LCS) of 87,416 participants enrolled in an international, prospective study named the International Early Lung Cancer Action Program.

Lung cancer is the leading cause of cancer death. The American Lung Association states the average 5-year survival rate is 18.6%. Only 16% of the cancers are caught early and more than half of people with lung cancer die within a year of diagnosis.
 

Participants’ 20-year survival rate 80%

Results of this large international study showed the overall 20-year survival rate for the 1,285 screening participants diagnosed with early-stage cancer was 80% (95% confidence interval, 77%-83%). Among the 1,285 diagnosed, 83% had stage 1 cancer, Dr. Henschke said.

Lung cancer survival (LCS) was 100% for the 139 participants with nonsolid nodule consistency and for the 155 participants with part-solid consistency. LCS was 73% (95% CI, 69%-77%) for the 991 with solid consistency, and for clinical stage IA participants LCS was 86% (95% CI, 83%-89%), regardless of consistency.

For participants with pathologic stage IA lung cancer 10 mm or less in average diameter, the 20-year survival rate with identification and resection was 92% (95% CI, 87%-96%).

No lung cancer deaths were identified in the part-solid and nonsolid cancers, the researchers report.

These results show the 10-year findings from 2006 published in the New England Journal of Medicine, which also showed 80% survival rates with low-dose CT, have persisted, she said.

At the time of the 2006 paper, 95% of Americans diagnosed with lung cancer died from it, Dr. Henschke said.

Dr. Henschke notes that by the time symptoms appear, lung cancer is often advanced, so the best tool for detecting early-stage lung cancer is enrolling in an annual screening program.

When cancer is small enough and can be surgically removed, patients can be effectively cured long-term, she said.

“In the future, perhaps blood markers will allow us to detect it in the first half of the life cycle of lung cancer instead of CT at the beginning of the second half of the life cycle,” Dr. Henschke said.

“The study raises the power of prospective data collection in the context of clinical care as recommended by the Institute of Medicine long ago,” she said.
