Black patients now central to lung cancer screening guidelines
according to a report in JAMA Oncology.
Fewer Black people qualified for screening in the earlier guideline of which the majority of its participants were White. In response, the group changed the screening eligibility age from 55 to 50 years and lowered the smoking pack by year requirement from 30 to 20 years.
The changes showed that Black smokers tend to develop lung cancer earlier and with fewer pack-years than White smokers.
The study details
To gauge the impact, investigators from Wayne State University, Detroit, reviewed 912 patients with lung cancer and 1,457 controls without lung cancer to see who would have qualified for screening under the 2013 and 2021 criteria.
They were participants in the Detroit-area INHALE (Inflammation, Health, Ancestry, and Lung Epidemiology) study from 2012 to 2018. Over 30% were Black.
“Lowering the age and smoking criteria successfully bridged the gap in racial disparity,” said investigators led by Chan Yeu Pu, MD, a lung cancer specialist at Wayne State University.
With the 2021 criteria, 65% of White patients and 63% of Black patients with lung cancer would have been eligible for screening. Under the 2013 guidance, 52% of White patients were eligible for screening, but only 42% of Black patients.
The update also eliminated racial disparities among controls. The new guidance excluded 48% of White controls without lung cancer from screening and 50% of Black controls. The 2013 criteria excluded fewer White controls (61%) than Black control subjects (70%).
“As expected, broader inclusion criteria increased sensitivity, but at the cost of decreased specificity,” the investigators wrote.
Why is screening important?
The hope of screening is to catch lung cancer early, when curative surgical resection is still possible, the team wrote, but although screening has increased over the years, uptake remains dismal, just 5% in 2018, for instance.
In an editorial, Philadelphia-area thoracic surgeons Jonathan Nitz, MD, and Cherie Erkmen, MD, wrote that “multiple and changing criteria” and “nebulous payment plans” have made “for a confusing message. ... We need standardized” guidelines to deliver “a clear message about lung cancer screening.”
The fact that nearly two-thirds of lung cancer patients wouldn’t have qualified for screening under current guidelines also needs to be addressed. “We need standardized practice guidelines based on evidence from diverse populations and policies to ensure equitable access for high-risk individuals. Although this study demonstrates improved, calculated sensitivity of the 2021 USPSTF guidelines to detect lung cancer, these refinements of criteria do not address the nearly two-thirds of patients with diagnosed lung cancer who are not eligible for screening. There is a pressing need to redefine screening criteria,” Dr. Nitz and Dr. Erkmen wrote.
Both the 2013 and 2021 guidelines were outperformed in the study by the 2012 modification of the model from the Prostate, Lung, Colorectal, and Ovarian Cancer (PLCOm2012 criteria), but only marginally so in the case of USPSTF’s 2021 guidance.
PLCOm2012 screening eligibility, however, are based on a complicated risk factor assessments that include race but also education level and other factors which might not be readily available in electronic records. USPSTF’s criteria “are much more straightforward to use in a clinical setting,” the investigators noted.
Study subjects were 21-89 years old and were in their early 60s, on average. Just over half were women. The analysis excluded lung cancer patients and controls who had never smoked.
The authors noted some limitations, including the retrospective nature of the study, plus, few lung cancers were diagnosed among the control group, which were not only small, but they did not include follow-ups with CT scans.
The work was funded by the National Institutes of Health and the Herrick Foundation. Dr. Pu didn’t have any commercial disclosures. One investigator disclosed personal fees from Takeda, AstraZeneca, Genentech/Roche, Pfizer, and other companies. Dr. Erkmen reported an American Cancer Society-Pfizer Award to address disparities.

FROM JAMA ONCOLOGY
Earlier diagnosis could prevent more than 20% of cancer deaths
Those figures translate to 2,064 to 2,677 fewer cancer deaths annually in the state of New South Wales between 2005 and 2014, the most recent period studied.
“While it is well established that diagnosing cancers at an earlier stage is ‘better,’ our study is unique in that it quantifies what that ‘better’ might look like in terms of how many deaths would be avoided within 10 years of diagnosis,” the authors write in an article published online Jan. 17 in the International Journal of Cancer. “By doing so, it is hoped that these results will provide continued motivation to develop more effective strategies to diagnose cancers at an earlier stage.”
Of course, achieving such a “stage-shift in practice is difficult,” study author Xue Qin Yu, PhD, of The Daffodil Centre in Sydney and colleagues, acknowledge. First, Dr. Yu and colleagues note, “diagnosis at an earlier stage can be challenging due to the nonspecific nature of many common symptoms which may not be recognized by either patients or doctors.” Plus, they add, a challenge for diagnosing cancers at an earlier stage “is the overall low uptake of screening.”
For their study, the researchers used data from a cohort of more than 716,000 people aged 15 to 89 years diagnosed with a solid cancer in New South Wales between 1985 and 2014 and followed through 2015.
To estimate how many deaths could be avoided if tumors were caught earlier, the authors looked at two scenarios. In scenario 1, they assumed all known cases of distant cancer were instead diagnosed at the regional stage, and in scenario 2, they assumed half of the cases were diagnosed as regional and half as localized disease.
Under the conservative scenario 1, about 18% of the observed cancer deaths in males and 26% in females could be avoided. In total, this corresponded to 21% of observed deaths.
Colorectal cancer topped the list of avoidable deaths in both men (27%) and women (33%), followed by prostate cancer in men (19%), breast cancer in women (18%), and melanoma in women (16%) and men (13%).
Under scenario 2, 24% of cancer deaths in males and 32% in females – or 28% overall – were avoidable.
The researchers caution that their study is limited by a high proportion of cases of unknown stage. Still, they say their findings are consistent with results from the United States indicating 15% to 25% of cancer-related deaths were potentially avoidable if tumors were detected before metastasizing.
“Given our study cohort was sourced from a population-based cancer registry with complete enumeration of cancers diagnosed during the study period, it is likely that our study findings, particularly in terms of the population rate of avoidable deaths, would be generalizable to other populations with similar characteristics,” Dr. Yu and colleagues write. “However, results may be different in countries that have a different mix of cancer types or distribution of stage at diagnosis.”

E-cigarettes don’t help smokers quit, suggests new research
From 2013 to 2017, e-cigarette sales in the United States nearly doubled, driven by a rapid uptake of use by adolescents, wrote Riufeng Chen, MD, of the University of California, San Diego, and colleagues, in their paper published in Tobacco Control. However, the subsequent effect of increased e-cigarette use on smoking cessation have not been examined, they said.
In their study, Dr. Chen and colleagues analyzed data from 3,578 previous-year smokers with a recent quit attempt and 1,323 recent former smokers who were part of the PATH cohort in 2017. The participants reported using e-cigarettes or other products to quit cigarette smoking. The primary outcomes were at least 12 months of cigarette abstinence, and tobacco abstinence in 2019. In 2017, 32.8% of established smokers reported trying to quit. Of these, 12.6% used e-cigarettes to help them quit. Cigarette abstinence for at least 12 months for these individuals was 9.9%, which was lower than for those who used either nicotine replacement therapy or a pharmaceutical aid only (15.2%), and about half of the 18.6% abstinence in those who used no products to help them quit.
“In our study, e-cigarettes resulted in seven fewer successful quitters than those who used pharmaceutical aids,” emphasized corresponding author, John P. Pierce, PhD, of the University of California, San Diego.
Among smokers attempting to quit, the adjusted risk difference for cigarette abstinence for a least 12 months with e-cigarettes vs. pharmaceutical aids was –7.3%, and –7.7% for e-cigarettes vs. other smoking cessation methods.
*“Among recent former smokers who had switched to daily use of e-cigarettes in 2017, 43.2% had successfully quit cigarette smoking by 2019, which was similar to those who used e-cigarettes on a nondaily basis (34.6%) or to those who switched to another tobacco product, whether daily (43.6%) or nondaily (44.7%),” the researchers wrote.
The rapid growth in e-cigarette use between 2014 and 2017 has been attributed in part to aggressive marketing of high-nicotine e-cigarettes, they said. “The high-nicotine JUUL e-cigarette has been noted as the closest match to cigarettes in both nicotine delivery and user satisfaction, which should make it one of the best candidates as a product to which smokers could switch in order to maintain their nicotine habit,” they said in their discussion of the findings.
More research needed
The researchers acknowledged the need to review more recent data.
“When we looked ahead to 2019, recent former smokers had started using high-nicotine e-cigarettes. The effectiveness of high-nicotine e-cigarettes at preventing relapse will require another follow-up PATH survey,” they said.
Among recent former smokers, 2.2% reported switching to a high-nicotine e-cigarette. Although individuals who switched to e-cigarettes showed a higher rate of relapse to cigarettes than those who did not switch to other tobacco or e-cigarette products, this difference was not significant.
The study findings were limited by several factors including the observational design and inability to control for all potential confounding factors, the researchers noted. However, the results were strengthened by the use of a large and representative study population, and the inclusion of biological samples to validate self-reported smoking, they said.
Several findings surprised study author
Dr. Pierce said he was surprised by several aspects of the study findings.
“First of all, contrary to what we expected, there was a 25% decline in using e-cigarettes to quit, compared to the previous year (not the 40% increase that was expected from the increase in e-cigarette sales) and almost no smokers were using high-nicotine JUUL products to help them quit,” he said. “In this study, e-cigarettes were much less helpful (7 less successful quitters per 100) than pharmaceutical cessation aids in helping people quit,” he added.
“The fact that the proportion of smokers using e-cigarettes for cessation dropped from 17% to 12% was unexpected, and it suggests that the belief that they are a cessation aid is declining,” he said.
The implication for clinical practice is that e-cigarettes are not a useful tool for smoking cessation, Dr. Pierce said. “We are not finding any evidence in this very large nationally representative study that smokers who switch to getting their nicotine from e-cigarettes are less likely to relapse back to cigarette smoking,” he said.
“We don’t know about the high-nicotine versions,” he added.
New review advises against e-cigarettes for cessation
A recent review article published in JAMA supported the use of pharmacotherapy and behavioral support for smokers wanting to quit. In the review, Nancy A. Rigotti, MD, of Massachusetts General Hospital, Boston, and colleagues summarized the evidence for managing tobacco smoking in clinical practice.
“The health risk from cigarette smoking is primarily due to chemicals produced by the burning of tobacco and not to nicotine,” they noted. However, the physical dependence on nicotine makes quitting a challenge, but it is one worth pursuing, the authors said.
The authors of this review identified 30 reviews, 12 randomized clinical trials, and 7 recent guidelines and evidence reviews. Their key message: Pharmacotherapy and behavioral support are effective when used alone, but even more effective when combined. Pharmacotherapy helps reduce the symptoms of nicotine withdrawal, while behavioral intervention tackles the challenge of changing learned behaviors associated with smoking, the researchers said.
Although combining medications, such as varenicline and nicotine replacement therapy or bupropion might improve successful quit rates, these combinations have not been well studied, they noted.
With regard to e-cigarettes, the researchers cited a 2021 Cochrane review of 16,759 individuals who used e-cigarettes for smoking cessation, which found no evidence of harm, but insufficient evidence to asses the balance of risks vs. benefits.
In addition to the lack of randomized trials, “the FDA regulates e-cigarettes as tobacco products, not as medical products and has not evaluated any e-cigarette for medical use as a cessation aid,” the authors of the new review noted.
The review was limited by several factors, including the lack of quality assessment for the selected studies and the exclusion of pharmacotherapy not licensed in the United States.
Commenting on the JAMA paper, Dr. Pierce said, “This review looks like a number of Cochrane Reports that have been published recently. Of course, it only considers randomized trials and not population evidence.”
“If public health had limited itself to this form of evidence, then we still would not know that smoking caused cancer,” he noted. “Randomized trials are very important for testing new drugs; they use selected populations and provide considerable support that is not available in the real world. Sometimes they do not generalize to the population.”
Findings may guide patient conversations
The Tobacco Control study was important, because few studies on e-cigarettes have been conducted, said Linda Girgis, MD, a family physician in private practice in South River, N.J., in an interview.
“As clinicians, we do not have a lot of data available in order to make clinical decisions that are evidence based. Also, getting patients to quit smoking is often very difficult, and having more tools available is a great benefit; however, we need to have the evidence that these tools are effective,” she said.
Dr. Girgis also said she was not surprised by the findings.
“Patients still have the same concerns from e-cigarettes regarding nicotine exposure, but just to a lesser degree; and we still don’t know the long-term effects of e-cigarette use, she said. Based on these studies, recommending e-cigarettes for smokers looking to quit may not be the best method, she noted.
“While it may seem reasonable that exposing lungs to lower doses of nicotine will reduce harm, we need to see actual evidence of this. Also, we also need to study the additives that are frequently used in e-cigs, such as artificial flavorings, to see what harms they may pose, she emphasized.
With regard to the JAMA review, Dr. Girgis said she agreed with the recommendations for pharmacotherapy and behavior therapy as first-line treatments for smoking cessation. “There is evidence regarding the efficacy and safety of these methods, and they have been used for decades,” she said.
Dr. Girgis added that there is a role for e-cigarettes in smoking cessation strategies as a method of harm reduction, but pointed out the problem of many people thinking these products are safe and not understanding the hazards they pose.
“They think they can replace smoking with e-cigarettes and be safe from the health risks associated with smoking. I think if the plan were to switch to e-cigarettes for a short period and then quit, there would be a role,” Dr. Girgis said. “However, replacing one risk for another may reduce harm, but doesn’t eliminate it.”
“To continue to use e-cigarettes indefinitely should not be the goal,” she added.
The Tobacco Control study was funded by the National Institutes of Health and the Tobacco-Related Disease Research Program of the University of California. The researchers had no financial conflicts to disclose.
The JAMA study was funded in part by a grant from the National Institute for Health Research, via Cochrane Infrastructure funds to the Cochrane Tobacco Addiction Group. Lead author Dr. Rigotti disclosed funding from the National Heart, Lung, and Blood Institute and Achieve Life Sciences and personal fees from UpToDate and Achieve Life Sciences. Dr. Girgis had no financial conflicts to disclose.

A recent review article published in JAMA supported the use of pharmacotherapy and behavioral support for smokers wanting to quit. In the review, Nancy A. Rigotti, MD, of Massachusetts General Hospital, Boston, and colleagues summarized the evidence for managing tobacco smoking in clinical practice.
“The health risk from cigarette smoking is primarily due to chemicals produced by the burning of tobacco and not to nicotine,” they noted. However, the physical dependence on nicotine makes quitting a challenge, but it is one worth pursuing, the authors said.
The authors of this review identified 30 reviews, 12 randomized clinical trials, and 7 recent guidelines and evidence reviews. Their key message: Pharmacotherapy and behavioral support are effective when used alone, but even more effective when combined. Pharmacotherapy helps reduce the symptoms of nicotine withdrawal, while behavioral intervention tackles the challenge of changing learned behaviors associated with smoking, the researchers said.
Although combining medications, such as varenicline and nicotine replacement therapy or bupropion might improve successful quit rates, these combinations have not been well studied, they noted.
With regard to e-cigarettes, the researchers cited a 2021 Cochrane review of 16,759 individuals who used e-cigarettes for smoking cessation, which found no evidence of harm, but insufficient evidence to asses the balance of risks vs. benefits.
In addition to the lack of randomized trials, “the FDA regulates e-cigarettes as tobacco products, not as medical products and has not evaluated any e-cigarette for medical use as a cessation aid,” the authors of the new review noted.
The review was limited by several factors, including the lack of quality assessment for the selected studies and the exclusion of pharmacotherapy not licensed in the United States.
Commenting on the JAMA paper, Dr. Pierce said, “This review looks like a number of Cochrane Reports that have been published recently. Of course, it only considers randomized trials and not population evidence.”
“If public health had limited itself to this form of evidence, then we still would not know that smoking caused cancer,” he noted. “Randomized trials are very important for testing new drugs; they use selected populations and provide considerable support that is not available in the real world. Sometimes they do not generalize to the population.”
Findings may guide patient conversations
The Tobacco Control study was important, because few studies on e-cigarettes have been conducted, said Linda Girgis, MD, a family physician in private practice in South River, N.J., in an interview.
“As clinicians, we do not have a lot of data available in order to make clinical decisions that are evidence based. Also, getting patients to quit smoking is often very difficult, and having more tools available is a great benefit; however, we need to have the evidence that these tools are effective,” she said.
Dr. Girgis also said she was not surprised by the findings.
“Patients still have the same concerns from e-cigarettes regarding nicotine exposure, but just to a lesser degree; and we still don’t know the long-term effects of e-cigarette use, she said. Based on these studies, recommending e-cigarettes for smokers looking to quit may not be the best method, she noted.
“While it may seem reasonable that exposing lungs to lower doses of nicotine will reduce harm, we need to see actual evidence of this. Also, we also need to study the additives that are frequently used in e-cigs, such as artificial flavorings, to see what harms they may pose, she emphasized.
With regard to the JAMA review, Dr. Girgis said she agreed with the recommendations for pharmacotherapy and behavior therapy as first-line treatments for smoking cessation. “There is evidence regarding the efficacy and safety of these methods, and they have been used for decades,” she said.
Dr. Girgis added that there is a role for e-cigarettes in smoking cessation strategies as a method of harm reduction, but pointed out the problem of many people thinking these products are safe and not understanding the hazards they pose.
“They think they can replace smoking with e-cigarettes and be safe from the health risks associated with smoking. I think if the plan were to switch to e-cigarettes for a short period and then quit, there would be a role,” Dr. Girgis said. “However, replacing one risk for another may reduce harm, but doesn’t eliminate it.”
“To continue to use e-cigarettes indefinitely should not be the goal,” she added.
The Tobacco Control study was funded by the National Institutes of Health and the Tobacco-Related Disease Research Program of the University of California. The researchers had no financial conflicts to disclose.

From 2013 to 2017, e-cigarette sales in the United States nearly doubled, driven by a rapid uptake of use by adolescents, wrote Riufeng Chen, MD, of the University of California, San Diego, and colleagues, in their paper published in Tobacco Control. However, the subsequent effect of increased e-cigarette use on smoking cessation have not been examined, they said.
In their study, Dr. Chen and colleagues analyzed data from 3,578 previous-year smokers with a recent quit attempt and 1,323 recent former smokers who were part of the PATH cohort in 2017. The participants reported using e-cigarettes or other products to quit cigarette smoking. The primary outcomes were at least 12 months of cigarette abstinence, and tobacco abstinence in 2019. In 2017, 32.8% of established smokers reported trying to quit. Of these, 12.6% used e-cigarettes to help them quit. Cigarette abstinence for at least 12 months for these individuals was 9.9%, which was lower than for those who used either nicotine replacement therapy or a pharmaceutical aid only (15.2%), and about half of the 18.6% abstinence in those who used no products to help them quit.
“In our study, e-cigarettes resulted in seven fewer successful quitters than those who used pharmaceutical aids,” emphasized corresponding author, John P. Pierce, PhD, of the University of California, San Diego.
Among smokers attempting to quit, the adjusted risk difference for cigarette abstinence for a least 12 months with e-cigarettes vs. pharmaceutical aids was –7.3%, and –7.7% for e-cigarettes vs. other smoking cessation methods.
*“Among recent former smokers who had switched to daily use of e-cigarettes in 2017, 43.2% had successfully quit cigarette smoking by 2019, which was similar to those who used e-cigarettes on a nondaily basis (34.6%) or to those who switched to another tobacco product, whether daily (43.6%) or nondaily (44.7%),” the researchers wrote.
The rapid growth in e-cigarette use between 2014 and 2017 has been attributed in part to aggressive marketing of high-nicotine e-cigarettes, they said. “The high-nicotine JUUL e-cigarette has been noted as the closest match to cigarettes in both nicotine delivery and user satisfaction, which should make it one of the best candidates as a product to which smokers could switch in order to maintain their nicotine habit,” they said in their discussion of the findings.
More research needed
The researchers acknowledged the need to review more recent data.
“When we looked ahead to 2019, recent former smokers had started using high-nicotine e-cigarettes. The effectiveness of high-nicotine e-cigarettes at preventing relapse will require another follow-up PATH survey,” they said.
Among recent former smokers, 2.2% reported switching to a high-nicotine e-cigarette. Although individuals who switched to e-cigarettes showed a higher rate of relapse to cigarettes than those who did not switch to other tobacco or e-cigarette products, this difference was not significant.
The study findings were limited by several factors including the observational design and inability to control for all potential confounding factors, the researchers noted. However, the results were strengthened by the use of a large and representative study population, and the inclusion of biological samples to validate self-reported smoking, they said.
Several findings surprised study author
Dr. Pierce said he was surprised by several aspects of the study findings.
“First of all, contrary to what we expected, there was a 25% decline in using e-cigarettes to quit, compared to the previous year (not the 40% increase that was expected from the increase in e-cigarette sales) and almost no smokers were using high-nicotine JUUL products to help them quit,” he said. “In this study, e-cigarettes were much less helpful (7 less successful quitters per 100) than pharmaceutical cessation aids in helping people quit,” he added.
“The fact that the proportion of smokers using e-cigarettes for cessation dropped from 17% to 12% was unexpected, and it suggests that the belief that they are a cessation aid is declining,” he said.
The implication for clinical practice is that e-cigarettes are not a useful tool for smoking cessation, Dr. Pierce said. “We are not finding any evidence in this very large nationally representative study that smokers who switch to getting their nicotine from e-cigarettes are less likely to relapse back to cigarette smoking,” he said.
“We don’t know about the high-nicotine versions,” he added.

FROM TOBACCO CONTROL
New PET tracer detects more metastases in cancer patients
leading to predictions of a “paradigm shift” in this field.
The new tracer, 68Ga-FAPI (fibroblast activation protein inhibitor), detected more metastases in patients with lung cancer than the standard tracer, 18F-FDG (fluorodeoxyglucose), which has been in use for years.
The study by Chinese researchers was published in Radiology.
The team imaged 34 lung cancer patients with both 68Ga-FAPI and 18F-FDG. Performance was similar for primary tumors and for lung, liver, and adrenal gland metastases. However, FAPI imaging detected more metastases in the lymph nodes (356 vs. 320), brain (23 vs. 10), bone (109 vs. 91), and pleura (66 vs. 35). However, neither modality outperformed MRI for brain metastases, the researchers note.
An accompanying editorial concluded that 68Ga-FAPI PET/CT scanning marks “an important paradigm shift to more specific identification and characterization of a variety of cancers.”
“This may also mark the arrival of a new era in nuclear medicine where molecular imaging helps visualize and characterize the entire tumor burden in one setting,” write editorialists Francine Jacobson, MD, and Annick Van den Abbeele, MD, from Harvard University and Brigham and Women’s Hospital and the Dana Farber Cancer Center, in Boston.
This study was the one of the latest in a fast-growing body of literature reporting that tracers targeting FAP with a small-molecule inhibitor (FAPI) outperform FDG tracers, not just in lung cancer but across a broad range of cancers, including breast, hepatic, gastrointestinal, head-neck, gynecologic, and many other tumor types.
The possibilities aren’t limited to imaging, either. Several companies are planning trials to target FAP with radiopharmaceuticals.
FAP is associated with wound repair and is highly expressed by the fibroblasts tightly packed in with cancer cells, particularly in stroma-dense tumors. FAP is rarely expressed by healthy tissue.
The underlying idea is to deliver a radionuclide to cancer-associated fibroblasts, using either a positron emitter, such as gallium-68 (68Ga), for PET imaging or a beta particle or other short-radiation emitter to kill nearby cancer cells as part of treatment.
Targeting FAP holds the promise of PET imaging that is more selective for cancer than FDG. FDG resolution depends on glucose uptake, which is high in active tumors but is also high in inflamed tissues as well as in the brain, gastrointestinal tract, and other areas. Uptake by background tissue can make it difficult to distinguish tumors from their surroundings. FDG uptake can also be lower in small and indolent tumors.
On the therapy side, there’s hope that FAP targeting will lead to radiopharmaceuticals that work across tumor types, not just in specific cancers.
High interest in FAP
Overall, FAP “is a target of high interest for the whole medical oncology community. The preliminary data are good, but this will take a while” to get to market, said Jeremie Calais, MD, a nuclear medicine specialist and FAP researcher at the University of California, Los Angeles.
Interest in FAP as a radiopharmaceutical target is being driven by the success of two agents that have served as a kind of proof of concept, Dr. Calais said.
The first is Novartis’s 177Lu-PSMA-617, which was granted priority review by the U.S. Food and Drug Administration in September 2021 following phase 3 results that showed a progression-free survival benefit of about 5 months when added to standard of care for metastatic castration-resistant prostate cancer, as well as an overall survival benefit of 4 months.
PSMA-617 binds prostate cancer cells that express prostate-specific membrane antigen. The lutetium-177 (177Lu) bombards them with beta particles and gamma radiation.
FAP researchers are also encouraged by the success of 177Lu dotatate (Lutathera), from Advanced Accelerator Applications, which delivers the radionucleotide to gastroenteropancreatic neuroendocrine tumors that express somatostatin receptors.
The FDA approved this agent in 2018 in part on the basis of phase 3 results that found a 20-month progression-free survival of 65.2% when Lutathera was added to octreotide for metastatic disease vs. 10.8% when it wasn’t.
Novartis is now looking into developing FAP-targeted radiopharmaceuticals, along with Clovis and Point Biopharma, among others.
“That’s the key goal” of industry research, “more so than FAP as a diagnostic tool,” Dr. Calais commented to this news organization. There’s “huge potential” if it works out, he said, in part because it won’t be limited to one tumor type.
Clovis recently launched a phase 1/2 trial of its candidate, 177Lu-FAP-2286, for advanced/metastatic solid tumors.
In the company’s “luMIERE” trial, subjects will be infused with 68Ga-FAP-2286 to image the tumor. Once uptake is confirmed, they’ll be infused with 177Lu-FAP-2286 for treatment.
The two-step process – uptake confirmation, then treatment – is dubbed “theranostics” and is the standard approach for radiopharmaceutical therapy, Dr. Calais said.
His own team is working to confirm that imaging accurately reflects FAP expression in tumors by comparing preoperative imaging results with FAP expression on surgical specimens. So far, his team has found that they are strongly correlated.
FAPI PET imaging research is much farther along than therapeutic applications, with almost 200 research articles listed on PubMed in 2021, up from just 3 in 2018. One 2019 paper reported “remarkably high uptake and image contrast” across 28 cancers in 80 patients, including breast, esophagus, lung, pancreatic, head-neck, and colorectal tumors.
Imaging studies so far have tended to be small, with many currently focused on identifying the optimal molecule for targeting FAP and the best positron emitter to combine with it.
FAPI tracers are not available yet commercially, so researchers are creating them themselves. One team recently reported it’s recipe for automated synthesis using commercially available synthesis modules.
Sofie, a maker of FDG and other tracers, hopes to change that and is working to bring FAP tracers to market. The company announced in November 2021 a phase 2 study of 68Ga FAPI-46 to image pancreatic ductal adenocarcinoma. It’s the first step in a broader development program for oncologic and nononcologic indications, Sofie said in a press release.
Dr. Calais sees potential for indications where FAPI has already outperformed FDG in the literature, particularly for gastrointestinal cancers. He doesn’t think it will ever replace FDG for indications such as lymphoma, where it “works perfectly well.”
“On the other hand, you have lesions located in a tissue that has some background level” of FDG uptake. “These things are okay with FDG, but I think maybe FAP can help” because of the improved signal-to-noise ratio, Dr. Calais commented. Unlike FDG, “you mostly never see background uptake with FAP-imaging agents,” he said.
Other pluses include quicker distribution throughout the body than FDG, so scan times are shorter, and also patients do not need to fast beforehand.
Dr. Calais predicts that FAPI tracers will reach the market within 5 years.

It’s the first step in a broader development program for oncologic and nononcologic indications, Sofie said in a press release.
Dr. Calais sees potential for indications where FAPI has already outperformed FDG in the literature, particularly for gastrointestinal cancers. He doesn’t think it will ever replace FDG for indications such as lymphoma, where it “works perfectly well.”
“On the other hand, you have lesions located in a tissue that has some background level” of FDG uptake. “These things are okay with FDG, but I think maybe FAP can help” because of the improved signal-to-noise ratio, Dr. Calais commented. Unlike FDG, “you mostly never see background uptake with FAP-imaging agents,” he said.
Other pluses include quicker distribution throughout the body than FDG, so scan times are shorter, and also patients do not need to fast beforehand.
Dr. Calais predicts that FAPI tracers will reach the market within 5 years.

“I didn’t want to meet you.” Dispelling myths about palliative care
The names of health care professionals and patients cited within the dialogue text have been changed to protect their privacy.
but over the years I have come to realize that she was right – most people, including many within health care, don’t have a good appreciation of what palliative care is or how it can help patients and health care teams.
A recent national survey about cancer-related health information found that of more than 1,000 surveyed Americans, less than 30% professed any knowledge of palliative care. Of those who had some knowledge of palliative care, around 30% believed palliative care was synonymous with hospice.1 Another 15% believed that a patient would have to give up cancer-directed treatments to receive palliative care.1
It’s not giving up
This persistent belief that palliative care is equivalent to hospice, or is tantamount to “giving up,” is one of the most commonly held myths I encounter in everyday practice.
I knock on the exam door and walk in.
A small, trim woman in her late 50s is sitting in a chair, arms folded across her chest, face drawn in.
“Hi,” I start. “I’m Sarah, the palliative care nurse practitioner who works in this clinic. I work closely with Dr. Smith.”
Dr. Smith is the patient’s oncologist.
“I really didn’t want to meet you,” she says in a quiet voice, her eyes large with concern.
I don’t take it personally. Few patients really want to be in the position of needing to meet the palliative care team.
“I looked up palliative care on Google and saw the word hospice.”
“Yeah,” I say. “I hear that a lot. Well, I can reassure you that this isn’t hospice.
In this clinic, our focus is on your cancer symptoms, your treatment side effects, and your quality of life.”
She looks visibly relieved. “Quality of life,” she echoes. “I need more of that.”
“OK,” I say. “So, tell me what you’re struggling with the most right now.”
That’s how many palliative care visits start. I actually prefer if patients haven’t heard of palliative care because it allows me to frame it for them, rather than having to start by addressing a myth or a prior negative experience. Even when patients haven’t had a negative experience with palliative care per se, typically, if they’ve interacted with palliative care in the past, it’s usually because someone they loved died in a hospital setting and it is the memory of that terrible loss that becomes synonymous with their recollection of palliative care.
Many patients I meet have never seen another outpatient palliative care practitioner – and this makes sense – we are still too few and far between. Most established palliative care teams are hospital based and many patients seen in the community do not have easy access to palliative care teams where they receive oncologic care.2 As an embedded practitioner, I see patients in the same exam rooms and infusion centers where they receive their cancer therapies, so I’m effectively woven into the fabric of their oncology experience. Just being there in the cancer center allows me to be in the right place at the right time for the right patients and their care teams.
More than pain management
Another myth I tend to dispel a lot is that palliative care is just a euphemism for “pain management.” I have seen this less lately, but still occasionally in the chart I’ll see documented in a note, “patient is seeing palliative/pain management,” when a patient is seeing me or one of my colleagues. Unfortunately, when providers have limited or outdated views of what palliative care is or the value it brings to patient-centered cancer care, referrals to palliative care tend to be delayed.3
“I really think Ms. Lopez could benefit from seeing palliative care,” an oncology nurse practitioner says to an oncologist.
I’m standing nearby, about to see another patient in one of the exam rooms in our clinic.
“But I don’t think she’s ready. And besides, she doesn’t have any pain,” he says.
He turns to me quizzically. “What do you think?”
“Tell me about the patient,” I ask, taking a few steps in their direction.
“Well, she’s a 64-year-old woman with metastatic cancer.
She has a really poor appetite and is losing some weight.
Seems a bit down, kind of pessimistic about things.
Her scan showed some new growth, so guess I’m not surprised by that.”
“I might be able to help her with the appetite and the mood changes.
I can at least talk with her and see where she’s at,” I offer.
“Alright,” he says. “We’ll put the palliative referral in.”
He hesitates. “But are you sure you want to see her?
She doesn’t have any pain.” He sounds skeptical.
“Yeah, I mean, it sounds like she has symptoms that are bothering her, so I’d be happy to see her. She sounds completely appropriate for palliative care.”
I hear this assumption a lot – that palliative care is somehow equivalent to pain management and that unless a patient’s pain is severe, it’s not worth referring the patient to palliative care. Don’t get me wrong – we do a lot of pain management, but at its heart, palliative care is an interdisciplinary specialty focused on improving or maintaining quality of life for people with serious illness. Because the goal is so broad, care can take many shapes.4
In addition to pain, palliative care clinicians commonly treat nausea, shortness of breath, constipation or diarrhea, poor appetite, fatigue, anxiety, depression, and insomnia.
Palliative care is more than medical or nursing care
A related misconception about palliative care held by many lay people and health care workers alike is that palliative care is primarily medical or nursing care focused mostly on alleviating physical symptoms such as pain or nausea. This couldn’t be further from the truth.
We’ve been talking for a while.
Ms. Lopez tells me about her struggles to maintain her weight while undergoing chemotherapy. She has low-grade nausea that is impacting her ability and desire to eat more and didn’t think that her weight loss was severe enough to warrant taking medication.
We talk about how she may be able to use antinausea medication sparingly to alleviate nausea while also limiting side effects from the medications—which was a big concern for her.
I ask her what else is bothering her.
She tells me that she has always been a strong Catholic and even when life has gotten tough, her faith was never shaken – until now.
She is struggling to understand why she ended up with metastatic cancer at such a relatively young age—why would God do this to her?
She had plans for retirement that have since evaporated in the face of a foreshortened life.
Why did this happen to her of all people? She was completely healthy until her diagnosis.
Her face is wet with tears.
We talk a little about how a diagnosis like this can change so much of a person’s life and identity. I try to validate her experience. She’s clearly suffering from a sense that her life is not what she expected, and she is struggling to integrate how her future looks at this point.
I ask her what conversations with her priest have been like.
At this point you may be wondering where this conversation is going. Why are we talking about Ms. Lopez’s religion? Palliative care is best delivered through high functioning interdisciplinary teams that can include other supportive people in a patient’s life. We work in concert to try to bring comfort to a patient and their family.4 That support network can include nurses, physicians, social workers, and chaplains. In this case, Ms. Lopez had not yet reached out to her priest. She hasn’t had the time or energy to contact her priest given her symptoms.
“Can I contact your priest for you?
Maybe he can visit or call and chat with you?”
She nods and wipes tears away.
“That would be really nice,” she says. “I’d love it if he could pray with me.”
A few hours after the visit, I call Ms. Lopez’s priest.
I ask him to reach out to her and about her request for prayer.
He says he’s been thinking about her and that her presence has been missed at weekly Mass. He thanks me for the call and says he’ll call her tomorrow.
I say my own small prayer for Ms. Lopez and head home, the day’s work completed.

ICIs for NSCLC: Patients with ILD show greater risk
, a systematic review and meta-analysis indicated.
“Patients with preexisting ILD, especially symptomatic ILD, are frequently excluded from clinical trials so almost all the patients [we analyzed] were diagnosed with mild preexisting ILD,” said Yuan Cheng, MD, Peking University First Hospital, Beijing, China.
“At this stage, we think that mild ILD is not a contraindication to the use of anti-programmed death-1 (PD-1) and anti-programmed death-ligand 1 (PD-L1) treatment for patients with NSCLC but whether ICIs can be used in patients with moderate to severe ILD needs further study,” she added.
The study was published online Jan. 10 in the journal CHEST.
Ten studies
A total of 179 patients from 10 studies were included in the review and meta-analysis. Among these, six were retrospective case-control studies, one was a retrospective noncontrolled study and three were prospective, noncontrolled clinical trials. “All the included studies were from East Asian countries,” the authors noted.
Preexisting ILD was diagnosed by use of CT or high-resolution CT. The mean age of patients was 71 years (range, 33-85 years), 87% were male and 96% of the cohort had a history of smoking. Approximately one-quarter of patients with ILD had usual interstitial pneumonitis (UIP); about the same percentage had possible UIP; one-third were diagnosed with inconsistent UIP; 14% had nonspecific interstitial pneumonia (NSIP); and 6% had indeterminate UIP.
Patients received ICIs either as first-, second-, or third-line or higher therapy and all were treated with ICI monotherapy by way of either nivolumab (Opdivo), pembrolizumab (Keytruda), or atezolizumab (Tecentriq). About 10% of patients had a PD-L1 tumor proportion score (TPS) of less than 1%, one-quarter had a PD-L1 TPS of 1%-49%, and approximately two-thirds had a TPS of 50% or greater.
Objective response rates
Some 35% of patients with both NSCLC and preexisting ILD achieved an objective response rate (ORR) to ICI therapy and almost two-thirds of patients achieved disease control. However, there was considerable heterogeneity in ORRs between the studies where it ranged from 5.9% to 70%, the authors cautioned.
On meta-analysis, the pooled ORR was 34% (95% confidence interval, 20%-47%) but again, with significant heterogeneity (I2 = 75.9%). However, on meta-analysis of eligible studies, patients with NSCLC who had preexisting ILD were 99% more likely to achieve an ORR compared to those without ILD (odds ratio, 1.99; 95% CI, 1.31-3.00), the investigators pointed out.
The disease control rate (DCR) also varied considerably between studies from a low of 33.3% to a high of 100%, they added. On meta-analysis, the pooled DCR was 66% (95% CI, 56%-75%). “Meanwhile, in patients without preexisting ILD, the crude ORR and pooled ORR were 24.3% and 24% (95% CI, 17%-31%), respectively” – again with significant heterogeneity between studies (I2 = 87.4%).
In contrast to the ORR, there was no difference in the DCR between the two groups, with no evidence of heterogeneity. There were no significant differences between the two groups in either median progression-free survival (PFS) or overall survival (OS). In patients with NSCLC and preexisting ILD, median PFS ranged from 1.4 to 8 months whereas median OS ranged from 15.6 to 27.8 months.
For those without preexisting ILD, the median PFS ranged from 2.3 to 8.1 months while median OS ranged from 17.4 to 25.5 months.
ICI safety
In patients with NSCLC and preexisting ILD, the incidence of immune-related adverse events (irAes) of any grade was 56.7%, whereas the incidence of irAEs grade 3 and higher was 27.7%. “Among the 179 patients included in the studies, 45 developed any grade of CIP, corresponding to a crude incidence of 25.1%,” the authors noted – very similar to the pooled incidence of 27% on meta-analysis.
The pooled incidence of grade 3 and higher CIP in the same group of patients was 15%. The median time from initiation of ICIs to the development of CIP ranged from 31 to 74 days, but 88% of patients who developed CIP improved with appropriate treatment. In patients with NSCLC who did not have ILD, the pooled incidence of CIP was 10% (95% CI, 6%-13%), again with significant heterogeneity between studies (I2 = 78.8%). “Generally, CIP can be managed through ICI discontinuation with or without steroid administration,” the authors noted.
However, even if most CIP can be easily managed, “the incidence of severe CIP is higher [in NSCLC patients with preexisting ILD] than in other populations,” Dr. Chen observed. “So patients with preexisting ILD should be closely monitored during ICI therapy,” she added.
Indeed, compared with patients without preexisting ILD, grade 3 or higher CIP in patients with the dual diagnosis was significantly higher at an OR of 3.23 (95%, 2.06-5.06), the investigators emphasized.
A limitation to the review and systematic meta-analysis included the fact that none of the studies analyzed were randomized clinical trials and most of the studies were retrospective and had several other shortcomings.
Umbrella diagnosis
Asked to comment on the review, Karthik Suresh, MD, associate professor of medicine, Johns Hopkins University, Baltimore, pointed out that ILD is really an “umbrella” diagnosis that a few hundred diseases fit under, so the first question he and members of his multidisciplinary team ask is: What is the nature of the ILD in this patient? What is the actual underlying etiology?
It could, for example, be that the patient has undergone prior chemotherapy or radiation therapy and has developed ILD as a result, as Dr. Suresh and his coauthor, Jarushka Naidoo, MD, Sidney Kimmel Comprehensive Cancer Center, Baltimore, pointed out in their paper on how to approach patients with preexisting lung disease to avoid ICI toxicities. “We’ll go back to their prior CT scans and can see the ILD has been there for years – it’s stable and the patient’s lung function is not changing,” Dr. Suresh related to this news organization.
“That’s a very different story from a [patients] whom there are new interstitial changes, who are progressing and who are symptomatic,” he noted. Essentially, what Dr. Suresh and his team members want to know is: What is the specific subdiagnosis of this disease, how severe is it, and is it progressing? Then they need to take the tumor itself into consideration.
“Some tumors have high PD-L1 expression, others have low PD-L1 expression so response to immunotherapy is usually very different based on tumor histology,” Dr. Suresh pointed out. Thus, the next question that needs to be addressed is: What is the expected response of the tumor to ICI therapy? If a tumor is exquisitely sensitive to immunotherapy, “that changes the game,” Dr. Suresh said, “whereas with other tumors, the oncologist might say there may be some benefit but it won’t be dramatic.”
The third risk factor for ICI toxicity that needs to be evaluated is the patient’s general cardiopulmonary status – for example, if a patient has mild, even moderate, ILD but is still walking 3 miles a day, has no heart problems, and is doing fine. Another patient with the same severity of disease in turn may have mild heart failure, be relatively debilitated, and sedentary: “Performance status also plays a big role in determining treatment,” Dr. Suresh emphasized.
The presence of other pulmonary conditions such as chronic obstructive pulmonary disease – common in patients with NSCLC – has to be taken into account, too. Lastly, clinicians need to ask themselves if there are any alternative therapies that might work just as well if not better than ICI therapy for this particular patient. If the patient has had genomic testing, results might indicate that the tumor has a mutation that may respond well to targeted therapies. “We put all these factors out on the table,” Dr. Suresh said.
“And you obviously have to involve the patient, too, so they understand the risks of ICI therapy and together we decide, ‘Yes, this patient with ILD should get immunotherapy or no, they should not,’ “ he said.
The study had no specific funding. The study authors and Dr. Suresh have disclosed no relevant financial relationships.

, a systematic review and meta-analysis indicated.
“Patients with preexisting ILD, especially symptomatic ILD, are frequently excluded from clinical trials so almost all the patients [we analyzed] were diagnosed with mild preexisting ILD,” said Yuan Cheng, MD, Peking University First Hospital, Beijing, China.
“At this stage, we think that mild ILD is not a contraindication to the use of anti-programmed death-1 (PD-1) and anti-programmed death-ligand 1 (PD-L1) treatment for patients with NSCLC but whether ICIs can be used in patients with moderate to severe ILD needs further study,” she added.
The study was published online Jan. 10 in the journal CHEST.
Ten studies
A total of 179 patients from 10 studies were included in the review and meta-analysis. Among these, six were retrospective case-control studies, one was a retrospective noncontrolled study and three were prospective, noncontrolled clinical trials. “All the included studies were from East Asian countries,” the authors noted.
Preexisting ILD was diagnosed by use of CT or high-resolution CT. The mean age of patients was 71 years (range, 33-85 years), 87% were male and 96% of the cohort had a history of smoking. Approximately one-quarter of patients with ILD had usual interstitial pneumonitis (UIP); about the same percentage had possible UIP; one-third were diagnosed with inconsistent UIP; 14% had nonspecific interstitial pneumonia (NSIP); and 6% had indeterminate UIP.
Patients received ICIs either as first-, second-, or third-line or higher therapy and all were treated with ICI monotherapy by way of either nivolumab (Opdivo), pembrolizumab (Keytruda), or atezolizumab (Tecentriq). About 10% of patients had a PD-L1 tumor proportion score (TPS) of less than 1%, one-quarter had a PD-L1 TPS of 1%-49%, and approximately two-thirds had a TPS of 50% or greater.
Objective response rates
Some 35% of patients with both NSCLC and preexisting ILD achieved an objective response rate (ORR) to ICI therapy and almost two-thirds of patients achieved disease control. However, there was considerable heterogeneity in ORRs between the studies where it ranged from 5.9% to 70%, the authors cautioned.
On meta-analysis, the pooled ORR was 34% (95% confidence interval, 20%-47%) but again, with significant heterogeneity (I2 = 75.9%). However, on meta-analysis of eligible studies, patients with NSCLC who had preexisting ILD were 99% more likely to achieve an ORR compared to those without ILD (odds ratio, 1.99; 95% CI, 1.31-3.00), the investigators pointed out.
The disease control rate (DCR) also varied considerably between studies from a low of 33.3% to a high of 100%, they added. On meta-analysis, the pooled DCR was 66% (95% CI, 56%-75%). “Meanwhile, in patients without preexisting ILD, the crude ORR and pooled ORR were 24.3% and 24% (95% CI, 17%-31%), respectively” – again with significant heterogeneity between studies (I2 = 87.4%).
In contrast to the ORR, there was no difference in the DCR between the two groups, with no evidence of heterogeneity. There were no significant differences between the two groups in either median progression-free survival (PFS) or overall survival (OS). In patients with NSCLC and preexisting ILD, median PFS ranged from 1.4 to 8 months whereas median OS ranged from 15.6 to 27.8 months.
For those without preexisting ILD, the median PFS ranged from 2.3 to 8.1 months while median OS ranged from 17.4 to 25.5 months.
ICI safety
In patients with NSCLC and preexisting ILD, the incidence of immune-related adverse events (irAes) of any grade was 56.7%, whereas the incidence of irAEs grade 3 and higher was 27.7%. “Among the 179 patients included in the studies, 45 developed any grade of CIP, corresponding to a crude incidence of 25.1%,” the authors noted – very similar to the pooled incidence of 27% on meta-analysis.
The pooled incidence of grade 3 and higher CIP in the same group of patients was 15%. The median time from initiation of ICIs to the development of CIP ranged from 31 to 74 days, but 88% of patients who developed CIP improved with appropriate treatment. In patients with NSCLC who did not have ILD, the pooled incidence of CIP was 10% (95% CI, 6%-13%), again with significant heterogeneity between studies (I2 = 78.8%). “Generally, CIP can be managed through ICI discontinuation with or without steroid administration,” the authors noted.

Monotherapy or one-two punch against EGFR-mutant NSCLC?
It is indisputable that patients with newly diagnosed advanced non–small cell lung cancer (NSCLC) bearing mutations in the epidermal growth factor receptor (EGFR) pathway may benefit from targeted therapy with a tyrosine kinase inhibitor (TKI) directed against EGFR.
What’s less clear is whether monotherapy with an EGFR TKI or combination therapy with a TKI and chemotherapy, immunotherapy, monoclonal antibodies or other targeted agents is the preferred frontline strategy.
NSCLC guidelines from the National Comprehensive Cancer Network, for example, recommend that patients with EFGR mutations such as exon 19 deletion, discovered prior to first-line systemic therapy, should preferably received osimertinib (Tagrisso) or another TKI, such as erlotinib (Tarceva), afatinib (Gilotrif), gefitinib (Iressa) or dacomitinib (Vizimpro), or erlotinib with a VEGF inhibitor. For patients with EGFR mutations identified during first-line systemic therapy, NCCN recommends complete systemic therapy or interrupting it, followed by osimertinib as the preferred agent, or another TKI with or without a VEGF inhibitors.
Similarly, guidelines from the American Society of Clinical Oncology and Ontario Health recommend osimertinib monotherapy as a preferred first-line option for patients with L858R/exon 19 deletion EGFR mutations. Alternatives for patients for whom osimertinib is not available include gefitinib plus platinum/pemetrexed chemotherapy with maintenance pemetrexed, monotherapy with dacomitinib, or other targeted agents with or without VEGF inhibitors.
Combination or go it alone?
The guidelines are largely mute on the question of chemotherapy in this population, primarily because they have not caught up to clinical trial evidence, said Paul Wheatley-Price, MBChB, FRCP, MD, from the University of Ottawa Hospital Research Institute.
“There is recent data that looks quite promising on combining EGFR inhibitors with either chemotherapy or antiangiogenic drugs, but it’s too soon, I think, and while the trials are promising, there are still too many question marks over it to make it into the guidelines,” he said in an interview.
The question of frontline combinations vs. monotherapy in patients with advanced EGFR-mutated NSCLC was the subject of a recent “controversies in thoracic oncology” feature in the Journal of Thoracic Oncology, with Dr. Wheatley-Price and University of Ottawa colleague Sara Moore, MD, FRCPC, arguing that combining EGFR TKIs with either cytotoxic chemotherapy or antiangiogenic monoclonal antibodies targeting the vascular endothelial growth factor (VEGF) receptor has been shown consistently to improve progression-free survival (PFS) and in some cases overall survival (OS).
“There is a consistent drop-off in patients who receive second-line therapy, highlighting the importance of using combination therapy in the first-line setting to ensure patients will be exposed to multiple available therapies that may prolong survival. Chemotherapy-based combinations lead to improved response rates which may be especially helpful in patients with a significant burden of disease,” they wrote.
The authors noted that, compared with patients with wild-type EGFR, patients with EGFR-mutated NSCLC had a doubling of response rates to chemotherapy with a platinum-based doublet in the IPASS trial, suggesting that EGFR-mutated tumors may be more chemosensitive.
Promising trials, old drug
“Chemotherapy and EGFR TKIs may have a synergistic effect through combined reduction in vascular endothelial growth factor (VEGF)–mediated angiogenesis, and with EGFR TKIs counteracting chemotherapy-induced up-regulation of downstream EGFR signaling,” they wrote.
The authors cited two studies, one from Japan, and one from India, both of which showed significant improvements in response rates, PFS, and OS with the combination of gefitinib plus carboplatin and pemetrexed chemotherapy with pemetrexed maintenance vs. carboplatin alone,
“Now of course we don’t use gefitinib as our first-line treatment. In Canada and the United States, we use osimertinib, so certainly the chemotherapy/TKI combination, while it looks quite promising, was compared to an old control arm,” Dr. Wheatley-Price said.
He noted that the phase 3 FLAURA2 trial, currently underway, will address the question of whether adding osimertinib to a chemotherapy doublet with pemetrexed plus either carboplatin or cisplatin can improve PFS in patients with EGFR-positive locally advanced or metastatic NSCLC, compared with osimertinib alone.
The authors acknowledged that chemotherapy adds toxicities, compared with the use of TKI monotherapy, but added that, “even with the use of first-line osimertinib monotherapy, patients may still be exposed to chemotherapy with later lines of treatment. Therefore, combination therapy does not expose patients to new toxicity, it simply changes when they will be exposed to that toxicity during their treatment course.”
VEGF plus EGFR
Adding a VEGF-targeted monoclonal antibody or TKI to and EGFR TKI has shown consistent PFS benefits in the NEJ026, ARTEMIS, RELAY, and ACTIVE trials, Dr. Moore and Dr. Wheatley-Price noted.
“In all four trials, resistance testing at the time of progression revealed similar rates of T790M mutation in both arms, highlighting the potential role of optimizing the sequence of therapy with use of second-line osimertinib among those with a T790M resistance mutation,” they wrote.
All four trials also showed higher rates of adverse events in the combination arms, but most, except for hypertension, were low grade, and in the RELAY trial the added toxicities did not significantly affect patient quality of life, they said.
Monotherapy advocated
Although in agreement that the combination of gefitinib and chemotherapy has both PFS and OS benefits compared with monotherapy alone, “these combinations are not applicable to real-life practice given their use of first-generation EGFR TKIs rather than third-generation EGFR TKI osimertinib,” wrote Sophie Stock-Martineau, MD, FRCPC from Hôpital Maisonneuve-Rosemont and the University of Montreal, and Frances A. Shepherd, MD, FRCPC from the Princess Margaret Cancer Centre in Toronto, in an article touting EGFR monotherapy.
They stated that until the results of FLAURA2 are available “osimertinib alone remains the current standard first-line therapy in metastatic EGFRm+ NSCLC.”
“The addition of an antiangiogenic agent to an EGFR TKI mildly prolongs PFS; however, it does not yet translate into survival benefit. Not only does it add more toxicity to patients, but it also adds cost, which is far from negligible,” they wrote.
Dr. Stock-Martineau and Dr. Shepherd also noted that two phase 2 trials comparing afatinib with the EGFR monoclonal antibody cetuximab (Erbitux) showed no PFS or OS benefits in patients with untreated EGFR-mutated NSCLC and were terminated for lack of efficacy.
In addition, clinical trials of combinations of EGFR TKIs with immune checkpoint inhibitors or MET inhibitors have failed to date to demonstrate survival benefits, the authors said.
“No trials have yet revealed PFS or OS benefit with osimertinib combinations. Adding virtually all agents to EGFR TKIs has been associated with more toxicity to patients and a significant financial burden to the health care system. Combinations could potentially also worsen quality of life given their heightened toxicity profiles. Therefore, single-agent EGFR TKI, such as osimertinib, remains for now the standard of care in the first-line setting for advanced EGFRm+ NSCLC,” they concluded.
No funding sources for the articles were reported. All authors declared no conflicts of interest to disclose.

“No trials have yet revealed PFS or OS benefit with osimertinib combinations. Adding virtually all agents to EGFR TKIs has been associated with more toxicity to patients and a significant financial burden to the health care system. Combinations could potentially also worsen quality of life given their heightened toxicity profiles. Therefore, single-agent EGFR TKI, such as osimertinib, remains for now the standard of care in the first-line setting for advanced EGFRm+ NSCLC,” they concluded.
No funding sources for the articles were reported. All authors declared no conflicts of interest to disclose.
It is indisputable that patients with newly diagnosed advanced non–small cell lung cancer (NSCLC) bearing mutations in the epidermal growth factor receptor (EGFR) pathway may benefit from targeted therapy with a tyrosine kinase inhibitor (TKI) directed against EGFR.
What’s less clear is whether monotherapy with an EGFR TKI or combination therapy with a TKI and chemotherapy, immunotherapy, monoclonal antibodies or other targeted agents is the preferred frontline strategy.
NSCLC guidelines from the National Comprehensive Cancer Network, for example, recommend that patients with EFGR mutations such as exon 19 deletion, discovered prior to first-line systemic therapy, should preferably received osimertinib (Tagrisso) or another TKI, such as erlotinib (Tarceva), afatinib (Gilotrif), gefitinib (Iressa) or dacomitinib (Vizimpro), or erlotinib with a VEGF inhibitor. For patients with EGFR mutations identified during first-line systemic therapy, NCCN recommends complete systemic therapy or interrupting it, followed by osimertinib as the preferred agent, or another TKI with or without a VEGF inhibitors.
Similarly, guidelines from the American Society of Clinical Oncology and Ontario Health recommend osimertinib monotherapy as a preferred first-line option for patients with L858R/exon 19 deletion EGFR mutations. Alternatives for patients for whom osimertinib is not available include gefitinib plus platinum/pemetrexed chemotherapy with maintenance pemetrexed, monotherapy with dacomitinib, or other targeted agents with or without VEGF inhibitors.
Combination or go it alone?
The guidelines are largely mute on the question of chemotherapy in this population, primarily because they have not caught up to clinical trial evidence, said Paul Wheatley-Price, MBChB, FRCP, MD, from the University of Ottawa Hospital Research Institute.
“There is recent data that looks quite promising on combining EGFR inhibitors with either chemotherapy or antiangiogenic drugs, but it’s too soon, I think, and while the trials are promising, there are still too many question marks over it to make it into the guidelines,” he said in an interview.
The question of frontline combinations vs. monotherapy in patients with advanced EGFR-mutated NSCLC was the subject of a recent “controversies in thoracic oncology” feature in the Journal of Thoracic Oncology, with Dr. Wheatley-Price and University of Ottawa colleague Sara Moore, MD, FRCPC, arguing that combining EGFR TKIs with either cytotoxic chemotherapy or antiangiogenic monoclonal antibodies targeting the vascular endothelial growth factor (VEGF) receptor has been shown consistently to improve progression-free survival (PFS) and in some cases overall survival (OS).
“There is a consistent drop-off in patients who receive second-line therapy, highlighting the importance of using combination therapy in the first-line setting to ensure patients will be exposed to multiple available therapies that may prolong survival. Chemotherapy-based combinations lead to improved response rates which may be especially helpful in patients with a significant burden of disease,” they wrote.
The authors noted that, compared with patients with wild-type EGFR, patients with EGFR-mutated NSCLC had a doubling of response rates to chemotherapy with a platinum-based doublet in the IPASS trial, suggesting that EGFR-mutated tumors may be more chemosensitive.
Promising trials, old drug
“Chemotherapy and EGFR TKIs may have a synergistic effect through combined reduction in vascular endothelial growth factor (VEGF)–mediated angiogenesis, and with EGFR TKIs counteracting chemotherapy-induced up-regulation of downstream EGFR signaling,” they wrote.
The authors cited two studies, one from Japan, and one from India, both of which showed significant improvements in response rates, PFS, and OS with the combination of gefitinib plus carboplatin and pemetrexed chemotherapy with pemetrexed maintenance vs. carboplatin alone,
“Now of course we don’t use gefitinib as our first-line treatment. In Canada and the United States, we use osimertinib, so certainly the chemotherapy/TKI combination, while it looks quite promising, was compared to an old control arm,” Dr. Wheatley-Price said.
He noted that the phase 3 FLAURA2 trial, currently underway, will address the question of whether adding osimertinib to a chemotherapy doublet with pemetrexed plus either carboplatin or cisplatin can improve PFS in patients with EGFR-positive locally advanced or metastatic NSCLC, compared with osimertinib alone.
The authors acknowledged that chemotherapy adds toxicities, compared with the use of TKI monotherapy, but added that, “even with the use of first-line osimertinib monotherapy, patients may still be exposed to chemotherapy with later lines of treatment. Therefore, combination therapy does not expose patients to new toxicity, it simply changes when they will be exposed to that toxicity during their treatment course.”
VEGF plus EGFR
Adding a VEGF-targeted monoclonal antibody or TKI to and EGFR TKI has shown consistent PFS benefits in the NEJ026, ARTEMIS, RELAY, and ACTIVE trials, Dr. Moore and Dr. Wheatley-Price noted.
“In all four trials, resistance testing at the time of progression revealed similar rates of T790M mutation in both arms, highlighting the potential role of optimizing the sequence of therapy with use of second-line osimertinib among those with a T790M resistance mutation,” they wrote.
All four trials also showed higher rates of adverse events in the combination arms, but most, except for hypertension, were low grade, and in the RELAY trial the added toxicities did not significantly affect patient quality of life, they said.
Monotherapy advocated
Although in agreement that the combination of gefitinib and chemotherapy has both PFS and OS benefits compared with monotherapy alone, “these combinations are not applicable to real-life practice given their use of first-generation EGFR TKIs rather than third-generation EGFR TKI osimertinib,” wrote Sophie Stock-Martineau, MD, FRCPC from Hôpital Maisonneuve-Rosemont and the University of Montreal, and Frances A. Shepherd, MD, FRCPC from the Princess Margaret Cancer Centre in Toronto, in an article touting EGFR monotherapy.
They stated that until the results of FLAURA2 are available “osimertinib alone remains the current standard first-line therapy in metastatic EGFRm+ NSCLC.”
“The addition of an antiangiogenic agent to an EGFR TKI mildly prolongs PFS; however, it does not yet translate into survival benefit. Not only does it add more toxicity to patients, but it also adds cost, which is far from negligible,” they wrote.
Dr. Stock-Martineau and Dr. Shepherd also noted that two phase 2 trials comparing afatinib with the EGFR monoclonal antibody cetuximab (Erbitux) showed no PFS or OS benefits in patients with untreated EGFR-mutated NSCLC and were terminated for lack of efficacy.
In addition, clinical trials of combinations of EGFR TKIs with immune checkpoint inhibitors or MET inhibitors have failed to date to demonstrate survival benefits, the authors said.
“No trials have yet revealed PFS or OS benefit with osimertinib combinations. Adding virtually all agents to EGFR TKIs has been associated with more toxicity to patients and a significant financial burden to the health care system. Combinations could potentially also worsen quality of life given their heightened toxicity profiles. Therefore, single-agent EGFR TKI, such as osimertinib, remains for now the standard of care in the first-line setting for advanced EGFRm+ NSCLC,” they concluded.

Medicare NCDs hinder access to cancer biomarker testing for minorities
of data from patients with advanced non–small cell lung cancer (aNSCLC), metastatic colorectal cancer, metastatic breast cancer, or advanced melanoma. The finding was reported in JAMA Network Open.
Biomarker testing has become an essential tool in cancer care over the last decade. In 2011, for example, less than 1% of patients with aNSCLC, metastatic colorectal cancer, metastatic breast cancer, and advanced melanoma underwent NGS testing, but by 2019, 40% of patients with these cancers received the testing.
“Next-generation sequencing testing has become increasingly important because it enables identification of multiple biomarkers simultaneously and efficiently while minimizing the number of biopsies required,” wrote the authors, led by William B. Wong, PharmD, of Genentech.
It has been unknown whether for Medicare beneficiaries and the overall population, if the NCD affected health equity issues, the authors wrote. While increased use of appropriate targeted therapies facilitated by NGS testing is associated with improved survival rates in patients with advanced or metastatic cancer, variability in health care coverage policies has posed a significant barrier to obtaining NGS testing for cancer patients, specifically through policy coverage limitations. It has remained unclear if the NCD has influenced NGS testing coverage in insurance types (for example, Medicaid) encompassing a larger population of minority racial and ethnic groups often experiencing poorer care and outcomes.
The retrospective cohort analysis compared EHR data from 280 U.S. cancer clinics in the (800 sites of care) pre- versus post-NCD period for patients with aNSCLC, metastatic colorectal cancer, metastatic breast cancer, or advanced melanoma (January 2011–March 2020). Nearly 70% of all patients in the study were Medicare recipients who needed NCD approval to cover the cost of testing.
Among 92,687 patients (mean age, 66.6 years; 55.7% women), compared with Medicare beneficiaries, changes in pre- to post-NCD NGS testing trends were similar in commercially insured patients (odds ratio, 1.03; 95% CI, 0.98-1.08; P = .25). Pre- to post-NCD NGS testing trends increased at a slower rate among patients in assistance programs (OR, 0.93; 95% CI, 0.87-0.99; P = .03), compared with Medicare beneficiaries. The rate of increase for patients receiving Medicaid was not significantly different statistically compared with those receiving Medicare (OR, 0.92; 95% CI, 0.84-1.01; P = .07). Also, the NCD was not associated with racial and ethnic groups within Medicare beneficiaries alone or across all insurance types.
Compared with non-Hispanic White individuals, increases in average NGS use from the pre-NCD to post-NCD period were 14% lower (OR, 0.86; 95% CI, 0.74-0.99; P = .04) among African American and 23% lower (OR, 0.77; 95% CI, 0.62-0.96; P = .02) among Hispanic/Latino individuals; increases were similar, however, among Asian individuals and other races and ethnicities.
The authors observed that the post-NCD trend of increasing NGS testing seen in Medicare beneficiaries was similarly observed in those with commercial insurance. Testing rate differences, however, widened or were maintained after versus before the NCD in PAP (personal assistance program) and Medicaid beneficiaries relative to Medicare beneficiaries, suggesting that access to NGS testing did not improve equally across insurance types. Since Medicare coverage is determined at the state level, the authors urged research examining individual state coverage policies to further elucidate factors slowing uptake among Medicaid beneficiaries. “Additional efforts beyond coverage policies,” the authors concluded, “are needed to ensure equitable access to the benefits of precision medicine.”

Expert views diverge on adding chemotherapy to EGFR TKIs in EGFR-mutant NSCLC
One affirms single-agent EGFR TKI treatment, such as with osimertinib, as the current standard of care for first-line advanced metastatic EGFR-positive mNSCLC, and the other affirms clear benefits for first-generation EGFR TKIs combined with either chemotherapy or VEGF monoclonal antibodies.
In the analysis supporting combination therapy for mNSCLC, Sara Moore, MD, and Paul Wheatley-Price MD, wrote that while targeted therapy with EGFR TKIs is highly effective initially, resistance inevitably develops.
Recent data, they stated, have demonstrated that combination strategies can delay development of resistance and improve outcomes for mNSCLC populations. Combining first-generation EGFR TKIs with either chemotherapy or VEGF monoclonal antibodies has led to consistent improvement in progression-free survival (PFS) and overall survival (OS) in some cases. In the NEJ009 trial, the combination of chemotherapy (carboplatin and pemetrexed, with pemetrexed maintenance) plus gefitinib versus gefitinib alone improved response rate (84% vs. 67%, P < 0.001), PFS (median, 20.9 months vs. 11.2 months; P < .001), and OS (median, 50.9 months vs. 38.8 months; P = .021). An increase in adverse events in the chemotherapy arm led to a decrease in quality of life.
Another clinical trial (by Noronha and colleagues) conducted in India of the same combination found benefit for combination therapy in response rate (75% vs. 63%), PFS (median, 16 months vs. 8 months), and OS (not reached vs. 17 months). Grade 3 or higher adverse event rates were higher with the combination (51% vs. 25%) with quality of life was not yet reported.
While both trials have been criticized owing to a lack of standard T790M resistance testing and low use of osimertinib in subsequent lines of therapy, Dr. Moore and Dr. Wheatley-Price pointed out: “Even with the use of first-line osimertinib monotherapy, patients may still be exposed to chemotherapy with later lines of treatment. Therefore, combination therapy does not expose patients to new toxicity, it simply changes when they will be exposed to that toxicity during their treatment course.”
The importance of using combination therapy in the first-line setting, they stated, is underscored by the consistent drop-off in patients who receive second-line combination therapy. In the phase 3 FLAURA trial of first-line osimertinib monotherapy, of the patients who discontinued osimertinib, the most common reason for not receiving subsequent therapy was death (60% went on to receive further systemic therapy). This highlights the need to use the most effective treatments up front, Dr. Moore and Dr. Wheatley-Price wrote.
The four large trials of VEGF-targeted therapy with either monoclonal antibodies or TKIs added to first-generation EGFR TKIs have consistently shown improved PFS. Increased toxicities led to discontinuation of VEGF-targeted therapy in 20%-30%.
In the RELAY trial, however, despite more toxicities, quality of life was not diminished. In general, the authors concluded that long-term detriments to quality of life have not been demonstrated. Ongoing studies of osimertinib in combination with VEGF inhibition include a phase 1/2 trial with bevacizumab in previously untreated patients showing an 80% response rate (median PFS, 18.4 months) with no unexpected toxicity.
Chemotherapy-based treatment for mNSCLC with third-generation EGFR TKIs, in appropriately selected patients, the authors concluded, “can offer an additional standard-of-care option as first-line treatment of EGFR-mutant lung cancer.”
Since the introduction of EGFR TKIs, Sophie Stock-Martineau, MD and Frances A. Shepherd, MD noted in their analysis, researchers have aimed to improve their efficacy through combining them with other agents. The authors review research on the addition of chemo- or immunotherapy and agents targeting major resistance mechanisms such as MET. Their review of the same NEJ009 trial focuses, however, on the 65.3% (EGFR TKI plus chemotherapy) versus 31.0% (gefitinib alone) grade 3 adverse event rate, and the 51% versus 25% grade 3 adverse event rate in a similar trial by Noronha and colleagues. The review by Dr. Stock-Martineau and Dr. Shepherd further found that, while adding antiangiogenic agents to an EGFR TKI “mildly” prolongs PFS, survival benefits have not been demonstrated. The added costs, not just in toxicity, were a “far from negligible” $120,000 above the cost of bevacizumab alone for 16 treatments. Data from trials of immune checkpoint inhibitors added to EGFR TKIs reveal heightened toxicities and limited efficacy. Trials of EGFR monoclonal antibodies with an EGFR TKI showed no PFS or OS benefit and were terminated early. Similarly, evidence to date shows no benefit beyond that shown for EGFR TKI monotherapy with the addition of a MET inhibitor.
“Adding virtually all agents to EGFR TKIs has been associated with more toxicity to patients and a significant financial burden to the health care system,” Dr. Stock-Martineau and Dr. Shepherd concluded, further observing that combinations, given their heightened toxicity profiles, could potentially also worsen quality of life.
No conflicts of interest were reported by the authors of either study.

No conflicts of interest were reported by the authors of either study.

Abraxane still in short supply for cancer patients
forcing physicians to find alternatives for a drug once lauded for being easier to tolerate.
Abraxane (Bristol-Myers Squibb) is a paclitaxel albumin-bound injectable. It is different from alternative chemotherapy treatments like Taxol (paclitaxel) because it doesn’t use the solvents that can make Taxol difficult to tolerate. It was described as a “next-generation taxane” because it didn’t rely on solvents. It was approved in 2005 for metastatic breast cancer, then in 2012 for advanced non–small cell lung cancer, in 2013 for late-stage pancreatic cancer and in 2019 for people with PD-L1–positive metastatic triple-negative breast cancer.
The shortage, which was announced on Oct. 5, 2021, by the Food and Drug Administration, has led to some difficult decisions for patients and physicians. How long the shortage will last isn’t clear.
“I printed out [an] allotment sheet 2 days ago, and all it says [for Abraxane] is allocated,” said Kathy Oubre, MS, CEO of Pontchartrain Cancer Center, Hammond, La. “Everyone is keeping what they’ve got for their own patients, so there really isn’t anything available.”
The Pontchartrain Cancer Center sent two patients to the University of Texas MD Anderson Cancer Center, Houston, for continued treatment with Abraxane, but that option is costly and time consuming for patients. The two patients had the means to travel, but Ms. Oubre said that many others cannot afford to travel for treatment. “Everyone has patients who are living paycheck to paycheck who certainly couldn’t afford to do that. There are going to be patients across the nation that are not going to be able to have care as a result of these things.”
The supply problems are causing difficult decisions for physicians, who may have to switch a patient from an unavailable drug to an alternative that isn’t as effective, Ms. Oubre said. “I can’t imagine the stress and the sadness that the physicians have to feel when they have to go explain that to a patient. That runs counter to everything they are as physicians.”
Other strategies include chemo holidays and rounding down doses in patients with metastatic cancer, according to Camille Hill, PharmD, vice president of oncology pharmacy services, West Cancer Center, Germantown, Tenn.
Shortages and allocations are growing at an alarming rate, Ms. Oubre said. In her 15 years of working in the industry, “I don’t recall it ever being this challenging.” During a Zoom interview, she held up a lengthy list of drugs on allocation or unavailable that her pharmacy group purchasing organization sent her the previous week. “I don’t ever recall getting this kind of list. Every 3 days, I’m getting this. If it were just that one product, I can live with that. We figure it out. But it’s bigger than that.”
Worker shortages are exacerbating the issue. Ms. Oubre received a letter from a drug company describing its employee issues, which included chemists, plant workers, and loading dock staff. On top of that, delivery companies are experiencing staff shortages, which can result in more delays and complicate matters further. “It’s just compounding. These things can get really difficult very quickly. I don’t want to say we’re in crisis, and we’re not rationing care. We’re not in those buckets yet. But I would say that if these things don’t get better, it’s the first time in my work career that we are having those conversations of: ‘How we are going to plan for that it does come to that?’ ” she said.
“In general, with the pandemic, we have seen all sorts of just disruptions to the supply chain. So, I think you just do your best, you find alternatives for those patients that you can, and you come up with strategies. I don’t know that for Abraxane, or any other product, that I’d be particularly confident that we may not see another shortage,” Dr. Hill said.
