The combination of a patient-specific mRNA-based cancer vaccine (mRNA-4157/V940, Moderna and Merck) and the immune checkpoint inhibitor pembrolizumab significantly improved recurrence-free survival for patients with high-risk melanoma compared with pembrolizumab alone, according to the latest data from the KEYNOTE-942 trial.

This recurrence-free survival benefit corresponded to a 44% reduced risk of recurrence or death in patients who received the personalized vaccine plus pembrolizumab compared with the immunotherapy alone.

The randomized phase 2b trial is the first to show a positive result for a cancer vaccine in a randomized trial. The results, if confirmed in further studies, hold promise for treating other solid tumors with sensitivity to the programmed death-1 (PD-1) protein, investigators said.

“KEYNOTE-942 is the first randomized study to demonstrate improvement in recurrence-free survival in melanoma, or in any cancer in my view, with an individualized neoantigen vaccine approach,” trial investigator Jeffrey S. Weber, MD, PhD, of NYU Langone Perlmutter Cancer Center in New York, said during an oral abstract session at the annual meeting of the American Association for Cancer Research.

“I have every confidence that this strategy will be expanded to other histologies that are PD-1 sensitive, such as non–small cell lung cancer, renal cell cancer, hepatocellular cancer, gastroesophageal cancer, et cetera,” Dr. Weber said.

Invited discussant Margaret Callahan, MD, PhD, of Memorial Sloan Kettering Cancer Center in New York, called the results “exciting,” especially in light of previous results in cancer vaccine trials. “Despite hundreds of formulations and dozens of studies, cancer vaccines have been disappointing so far, and have largely failed to have a meaningful impact in oncology,” she said.
 

A promising personalized vaccine

The mRNA vaccine is individually tailored and encodes up to 34 patient-specific tumor neoantigens. The vaccine also acts as an adjuvant to strengthen the immune response.

Dr. Weber said that the “mRNA 4157 is what one would call an individualized neoantigen therapy. It will target an individual patient’s unique tumor mutations, and the revelation over the last 5-10 years, is that, for better or worse, virtually all the neoantigens are unique to an individual patient. There are very, very few true universal neoantigens, or at least universal neoantigens that could have clinical utility.”

The vaccines are developed from tumor biopsy tissues that then undergo whole exome and RNA sequencing to identify single nucleotide variants that are present in the tumor but not in normal tissue.

The findings are then fed into a computer algorithm that identifies potential neoepitope peptides that would bind well to the patient’s human leukocyte antigen (HLA) type and could evoke strong T-cell responses.

“Once they’re chosen, you concatenate the sequences together into a single-strand mRNA vaccine, it’s packaged with nanoparticles to encapsulate it, and there you have your mRNA vaccine,” Dr. Weber explained.

In the KEYNOTE-942 trial, the investigators randomly assigned patients with completely resected high-risk cutaneous melanoma on a 2:1 basis to receive mRNA-4157 via intramuscular injection every 3 weeks for a total of nine doses, plus intravenous pembrolizumab every 3 weeks for 18 cycles (107 patients) or pembrolizumab alone (50 patients). Median follow-up was 101 weeks in the combination group and 105 weeks in the pembrolizumab group.

Overall, the 18-month recurrence-free survival rates were 78.6% in the combination arm and 62.2% in the pembrolizumab arm. The recurrence-free survival rates corresponded to a 44% reduced risk of recurrence or death in patients who received the personalized vaccine plus pembrolizumab compared with those who received only pembrolizumab (hazard ratio [HR] for recurrence, 0.561; P =.0266).

Grade 3 or greater adverse events occurred in 25% of patients in the combination group and 18% of patients in the pembrolizumab group. The most common grade 3 event associated with the vaccine was fatigue. No grade 4 adverse events or deaths were associated with the vaccine, and the addition of the vaccine to pembrolizumab did not appear to increase risk for immune-mediated adverse events.

In a subanalysis, Dr. Weber and colleagues explored the relationship between tumor mutational burden and recurrence-free survival. Higher tumor mutational burden may mean more neoepitopes to target, which is helpful when developing personalized neoantigen vaccines, explained coinvestigator Ryan Sullivan, MD, associate director of the melanoma program at Mass General Cancer Center, Boston, who presented the subanalysis results.

The investigators performed whole exome and whole transcriptome sequencing of baseline tumor biopsy samples to determine the mutational burden of tumors and defined a high mutational burden as 10 or more mutations per megabase.

Overall, in the combination group, patients with a higher tumor mutational burden at baseline showed improved outcomes (HR, 0.652; 95% confidence interval [CI], 0.284-1.494), as did patients with a lower tumor mutational burden (HR, 0.586; 95% CI, 0.243-1.415).

The authors found the same was true for patients with high vs. low tumor inflammation scores (high: HR, 0.576; 95% CI, 0.209-1.591 vs. low: HR, 0.528; 95% CI, 0.253-1.101) and higher PD-L1 expression (PD-L1 positive: HR, 0.485; 95% CI, 0.226-1.039 vs. PD-L1 negative: HR, 0.162; 95% CI, 0.038-0.685).

The hazard ratios crossed 1, which suggest that the combination was similarly effective in all patient subsets, said Dr. Sullivan.

Dr. Callahan also highlighted that the P value was based on a one-side log-rank test, “a relatively low bar to jump over” and that there were slight imbalances in both PD-1 expression status and tumor mutational burden – both of which favored the vaccine group and may be associated with better recurrence-free survival.

The 16% difference in recurrence-free survival seen with the combination vs. pembrolizumab alone, if confirmed in further studies, “is clinically meaningful for high-risk patients,” said Dr. Callahan. “The authors are to be congratulated for presenting the first randomized study of a neoantigen vaccine with a clinical efficacy primary endpoint, and this is a trial that incorporates many of the lessons we’ve learned along the years.”

Dr. Sullivan also commented on the promising results. “The field of cancer vaccines is a wasteland of failed clinical trials after some initial promising data, so to have something like this where it does appear that this vaccine strategy works is good not only for patients with melanoma but for those people who have dedicated their lives to trying to develop cancer vaccines,” he said in an interview.

KEYNOTE-942 was funded by Moderna with collaboration from Merck. Dr. Weber has financial relationships with Merck, Moderna, and other companies. Dr. Sullivan has served as a paid consultant for Merck and has received research funding from the company. Dr. Callahan disclosed a consulting/advisory role with Moderna, Merck, and others.

Black patients with cancer are significantly more likely to experience cardiotoxicity and heart failure related to chemotherapy than White cancer patients are, a research review indicates.

“It’s important that both patients and clinicians be aware of these disparities so that more meaningful conversations around long-term cardiac health and cancer treatment can take place,” lead investigator Wondewossen Gebeyehu, with the University of Toronto, said in an interview.

However, patients “should not avoid chemotherapy, as the most important thing is making sure they get the best cancer treatment possible, and studies already show Black patients may get less optimal cancer treatments,” Mr. Gebeyehu added in a statement.

Ana Barac, MD, PHD, chair of cardio-oncology at Inova Schar Cancer Institute and Inova Heart and Vascular Institute, Fairfax, Va., who wasn’t involved in the study, agreed.

“The most important message is to look at preexisting cardiovascular disease, oncology diagnosis, and be aware of existing disparities in a specific cancer and CVD,” Barac said in an interview.

“What should NOT happen is to overinterpret this report of cardiotoxicity as an indication to modify/avoid planned cancer treatment to decrease cardiotoxicity. This approach could worsen oncology outcomes and lead to undertreatment of cancer, therefore posing real danger,” said Dr. Barac.

The study was presented at the American College of Cardiology Advancing the Cardiovascular Care of the Oncology Patient 2023 conference.
 

Causes unclear

Chemotherapy is known to increase the risk of cardiovascular heart failure and other forms of CVD, but less is known about racial disparities in the incidence of chemotherapy-induced cardiotoxicity.

Mr. Gebeyehu and colleagues conducted a systematic review and meta-analysis of the available literature to assess racial disparities in CV adverse effects among cancer patients who were treated with chemotherapeutic agents. They screened 7,057 studies, fully reviewed 57, and included 24 studies, representing 683,749 participants, in their analysis.

Breast cancer was the most commonly reported malignancy. Other common malignancies were prostate, kidney, and hematologic malignancies such as leukemia and lymphoma.

Chemotherapeutic agents included anthracyclines (doxorubicin, daunorubicin), trastuzumab, and hormonal therapies.

Black race or African ancestry was associated with increased odds of chemotherapy-associated cardiotoxicity (odds ratio, 1.71; 95% confidence interval, 1.40-2.10), as well as congestive heart failure (OR, 1.92; 95% CI, 1.68-2.19).

Mr. Gebeyehu said in an interview that it’s hard to speculate on causation with an analysis of preexisting data such as this. “Our initial analysis that we’ve reported on so far are unadjusted values, meaning they don’t adjust for those potential underlying factors,” he noted.

“However, some of the studies individually controlled for socioeconomic factors and still found increased vulnerability to chemotherapy-associated cardiotoxicity in patients of Black race or African ancestry,” Mr. Gebeyehu said.

“It’s certainly possible that a mix of both biological and socioeconomic factors are interacting to lead to these disparities. One example could be the underrepresentation of Black patients in clinical trials to develop drugs. These could lead to chemotherapeutic agents being poorly optimized in this population relative to other racial/ethnic groups,” he added.

Dr. Barac said this study adds to the growing body of evidence about the importance of racial disparities in CVD and cancer outcomes.

“It is important to note that only the unadjusted odds ratio was reported and that much more detail is needed to understand what may be underlying the disparities. It is critically important to await the adjusted analysis, as well as details of the type of cancers and treatment used, before clinical implications can be discussed,” said Dr. Barac, who served as codirector of the conference.

“The risk of cardiotoxicity needs to be presented in the context of the oncology and CV disease burden, as both can influence the risk, and there could be a synergistic effect of disparities,” Dr. Barac added.

The study had no specific funding. Mr. Gebeyehu and Dr. Barac disclosed no relevant conflicts of interest.

The U.S. Preventive Services Task Force currently recommends that breast cancer screening start at age 50 years, regardless of race or ethnicity.

But a new analysis of breast cancer deaths supports a “race and ethnicity-adapted” approach to breast screening, with Black women starting screening 8 years sooner – at age 42.

The current “one-size-fits-all” policy to screen the entire female population from a certain age may be “neither fair and equitable nor optimal,” noted the authors, led by Tianhui Chen, PhD, with Zhejiang Cancer Hospital, Hangzhou, China.

The study was published online in JAMA Network Open.

Laurie R. Margolies, MD, chief of breast imaging at the Dubin Breast Center of the Mount Sinai Tisch Cancer Center in New York City, agreed.

Black women get breast cancer at a much younger age, are less likely to be diagnosed with early breast cancer, and are more likely to die of breast cancer, explained Dr. Margolies, who was not involved in the study.

“That’s why the guidelines that say begin at age 50 are flawed and so dangerous,” she said in an interview with this news organization. “This study is really important to highlight that we’re missing an opportunity to detect and treat breast cancer early in the Black population.”

The current study explored the optimal race- and ethnicity-specific ages to initiate breast cancer screening to address racial disparities in breast cancer mortality.

Using a nationwide population-based cross-sectional study design, the team analyzed data on 415,277 women who died of breast cancer in the United States from 2011 to 2020.

The cohort was 75% White, 15% Black, 7% Hispanic, 3% Asian or Pacific Islander, and < 1% Native American or Alaska Native. A total of 115,214 women (28%) died before age 60. The team calculated the 10-year cumulative risk of breast cancer–specific death by age and by race and ethnicity.

For those aged 40-49, breast cancer mortality was highest among Black women (27 deaths per 100,000 person-years), followed by White women (15 deaths per 100,000 person-years) and American Indian/Alaska Native, Hispanic, and Asian/Pacific Islander women (11 deaths per 100,000 person-years).

If breast screening started at age 50 for the entire population, the mean 10-year cumulative risk of dying from breast cancer would be 0.329%. Black women reached this risk threshold level at age 42, whereas non-Hispanic White women reached the threshold at age 51, American Indian/Alaska Native and Hispanic women at age 57, and Asian/Pacific Islander women at age 61.

If screening started at age 45 for all women, the mean 10-year cumulative risk of breast cancer death would be 0.235%. Black women reached this risk threshold level at age 38, non-Hispanic White women at age 46, Hispanic women at age 49, Asian/Pacific Islander women at age 50, and American Indian/Alaska Native women at age 51.

If screening started at age 40 for all women, with a mean 10-year cumulative risk of 0.154%, Black women would reach this risk threshold at age 34, White women at age 41, Hispanic women at age 43, and American Indian/Alaska Native and Asian/Pacific Islander women at age 43.

Dr. Chen and colleagues concluded that failure to consider race and ethnicity in breast cancer screening guidelines “may pose a significant risk for greater harm to a group already at increased risk.

“Changing guidelines based on readily available risk factors, such as race and ethnicity, is possible and may be the first, yet important step toward a personalized and fair screening program,” the team explained.

Dr. Margolies said she believes individualized screening recommendations will likely come, but first, all women should start screening at age 40 instead of age 50.

“Most American women are starting in their 40s, or starting at 40, because we know what the current guidelines are,” she said. “The question that this study doesn’t answer is, is age 40 young enough for the Black population? Maybe it should be 35.”

The study was supported by grants from the National Key Research-Development Program of China and from the Ten-Thousand Talents Plan of Zhejiang Province and by Start-Up Funds for Recruited Talents in Zhejiang Cancer Hospital. Dr. Chen and Dr. Margolies have disclosed no relevant financial relationships.

The U.S. Preventive Services Task Force currently recommends that breast cancer screening start at age 50 years, regardless of race or ethnicity.

But a new analysis of breast cancer deaths supports a “race and ethnicity-adapted” approach to breast screening, with Black women starting screening 8 years sooner – at age 42.

The current “one-size-fits-all” policy to screen the entire female population from a certain age may be “neither fair and equitable nor optimal,” noted the authors, led by Tianhui Chen, PhD, with Zhejiang Cancer Hospital, Hangzhou, China.

Early menopause and delayed initiation of hormone therapy (HT) have been linked to an increase in Alzheimer’s disease (AD) pathology in women, a new imaging study shows.

Investigators found elevated levels of tau protein in the brains of women who initiated HT more than 5 years after menopause onset, while those who started the therapy earlier had normal levels.

Tau levels were also higher in women who started menopause before age 45, either naturally or following surgery, but only in those who already had high levels of beta-amyloid.

The findings were published online in JAMA Neurology.
 

Hotly debated

Previous research has suggested the timing of menopause and HT initiation may be associated with AD. However, the current research is the first to suggest tau deposition may explain that link.

“There have been a lot of conflicting findings around whether HT induces risk for Alzheimer’s disease dementia or not, and – at least in our hands – our observational evidence suggests that any risk is fairly limited to those rarer cases when women might delay their initiation of HT considerably,” senior investigator Rachel Buckley, PhD, assistant investigator in neurology at Massachusetts General Hospital and assistant professor of neurology at Harvard Medical School, Boston, told this news organization.

The link between HT, dementia, and cognitive decline has been hotly debated since the initial release of findings from the Women’s Health Initiative Memory Study, reported 20 years ago.

Since then, dozens of studies have yielded conflicting evidence about HT and AD risk, with some showing a protective effect and others showing the treatment may increase AD risk.

For this study, researchers analyzed data from 292 cognitively unimpaired participants (66.1% female) in the Wisconsin Registry for Alzheimer Prevention. About half of the women had received HT.

Women had higher levels of tau measured on PET imaging than age-matched males, even after adjustment for APOE status and other potential confounders.

Higher tau levels were found in those with an earlier age at menopause (P < .001) and HT use (P = .008) compared with male sex; later menopause onset; or HT nonuse – but only in patients who also had a higher beta-amyloid burden.

Late initiation of HT (> 5 years following age at menopause) was associated with higher tau compared with early initiation (P = .001), regardless of amyloid levels.
 

Surprising finding

Although researchers expected to find that surgical history (specifically oophorectomy) might have a greater impact on risk, that wasn’t the case.

“Given that bilateral oophorectomy involves the removal of both ovaries, and the immediate ceasing of estrogen production, I had expected this to be the primary driver of higher tau levels,” Dr. Buckley said. “But early age at menopause – regardless of whether the genesis was natural or surgical – seemed to have similar impacts.”

These findings are the latest from Dr. Buckley’s group that indicate that women tend to have higher levels of tau than men, regardless of preexisting amyloid burden in the brain.

“We see this in healthy older women, women with dementia, and even in postmortem cases,” Dr. Buckley said. “It really remains to be seen whether women tend to accumulate tau faster in the brain than men, or whether this is simply a one-shot phenomenon that we see in observational studies at the baseline.”

“One could really flip this finding on its head and suggest that women are truly resilient to the disease,” she continued. “That is, they can hold much more tau in their brain and remain well enough to be studied, unlike men.”

Among the study’s limitations is that the data were collected at a single time point and did not include information on subsequent Alzheimer’s diagnosis or cognitive decline.

“It is important to remember that the participants in this study were not as representative of the general population in the United States, so we cannot extrapolate our findings to women from a range of socioeconomic, racial and ethnic backgrounds or education levels,” she said.

The study’s observational design left researchers unable to demonstrate causation. What’s more, the findings don’t support the assertion that hormone therapy may protect against AD, Dr. Buckley added.

“I would more confidently say that evidence from our work, and that of many others, seems to suggest that HT initiated around the time of menopause may be benign – not providing benefit or risk, at least in the context of Alzheimer’s disease risk,” she said.

Another important takeaway from the study, Dr. Buckley said, is that not all women are at high risk for AD.

“Often the headlines might make you think that most women are destined to progress to dementia, but this simply is not the case,” Dr. Buckley said. “We are now starting to really drill down on what might elevate risk for AD in women and use this information to better inform clinical trials and doctors on how best to think about treating these higher-risk groups.”
 

New mechanism?

Commenting on the findings, Pauline Maki, PhD, professor of psychiatry, psychology and obstetrics & gynecology at the University of Illinois at Chicago, called the study “interesting.”

“It identifies a new mechanism in humans that could underlie a possible link between sex hormones and dementia,” Dr. Maki said.

However, Dr. Maki noted that the study wasn’t randomized and information about menopause onset was self-reported.

“We must remember that many of the hypotheses about hormone therapy and brain health that came from observational studies were not validated in randomized trials, including the hypothesis that hormone therapy prevents dementia,” she said.

The findings don’t resolve the debate over hormone therapy and AD risk and point to the need for randomized, prospective studies on the topic, Dr. Maki added. Still, she said, they underscore the gender disparity in AD risk.

“It’s a good reminder to clinicians that women have a higher lifetime risk of Alzheimer’s disease and should be advised on factors that might lower their risk,” she said.

The study was funded by the National Institutes of Health. Dr. Buckley reports no relevant financial conflicts. Dr. Maki serves on the advisory boards for Astellas, Bayer, Johnson & Johnson, consults for Pfizer and Mithra, and has equity in Estrigenix, Midi-Health, and Alloy.

Non-Hispanic persons of African ancestry typically have worse clinical outcomes from colorectal cancer (CRC) than individuals of other heritages, a disparity attributed to many factors, including socioeconomic, environmental, and genetic influences, as well as less access to care.

Results from a new genomic study provide greater clarity regarding the genetic piece of the puzzle: Persons of African background tend to have fewer targetable alterations, compared with patients of other races.

The findings were presented in a briefing and scientific poster session at the annual meeting of the American Association for Cancer Research.

Overall, the numbers to date show a clear trend: The incidence of and mortality from CRC are higher among Black patients than other populations. However, the extent to which genetic difference plays a role in these disparities remains unclear.

In the current study, researchers from Memorial Sloan Kettering (MSK) Cancer Center in New York explored how germline and somatic genomic alterations differ among patients of African ancestry, in comparison with those of European and other heritage, and how those differences might influence CRC outcomes.

Lead author Henry Walch, MS, a computational biologist at MSK, and colleagues compared genomic profiles among nearly 3,800 patients with CRC who were treated at MSK from 2014 to 2022. Patients in the study were classified by genetic ancestry as European (3,201 patients), African (236 patients), East Asian (253 patients), and South Asian (89 patients).

Tumor and normal tissues from the patients underwent next-generation DNA sequencing with a panel that covers 505 cancer-associated genes.

An analysis of overall survival by genetic ancestry confirmed findings from other studies: Overall survival was significantly worse among patients of African ancestry than among those of other groups (median 45.7 vs. 67.1 months).

The investigators used a precision oncology knowledge base (OncoKB) to assign levels of therapeutic actionability for each genomic alteration that was identified. The highest assigned value was for drugs that have been approved by the U.S. Food and Drug Administration and that target FDA-recognized biomarkers. The lowest value was assigned to biomarkers for which there was “compelling biological evidence” that the particular biomarker predicted response to a drug.

The team found that the percentage of patients who qualified for immunotherapy on the basis of microsatellite instability or high tumor mutational burden was significantly lower among patients of African heritage, compared with those of European heritage (13.5% vs. 20.4%; P = .008).

Compared with those of European ancestry, patients of African ancestry had significantly fewer actionable alterations (5.6% vs. 11.2%; P = .01). This difference was largely driven by the lack of targetable BRAF mutations (1.8% vs. 5.0%).

Mutations in APC, the most frequently altered gene in CRC, are typically associated with cancer outcomes, but the authors found that overall survival was similar for patients of African heritage regardless of whether they had altered or wild-type APC (median overall survival, 45.0 months for altered APC vs. 45.9 months for wild-type APC; P = .91). However, a significant association between APC status and overall survival was observed for patients of European ancestry (median, 64.6 months for altered APC vs. 45.6 months for wild-type APC; P < .0001).

Analyses that accounted for sex, age, primary tumor location, and stage at diagnosis also showed an association between APC status and overall survival for patients of European heritage (hazard ratio, 0.64), but not for patients of African heritage (HR, 0.74, P = .492).

Mr. Walch noted that a limitation of the study is that information regarding comprehensive treatment, environmental exposures, lifestyle, and socioeconomic factors was not available for the analysis but that these elements likely play an important role in patient outcomes.

“This is a complex problem involving many unseen factors, and the genomic landscape is a piece of a much larger puzzle,” said Mr. Walch.

Non-Hispanic persons of African ancestry typically have worse clinical outcomes from colorectal cancer (CRC) than individuals of other heritages, a disparity attributed to many factors, including socioeconomic, environmental, and genetic influences, as well as less access to care.

Results from a new genomic study provide greater clarity regarding the genetic piece of the puzzle: Persons of African background tend to have fewer targetable alterations, compared with patients of other races.

The findings were presented in a briefing and scientific poster session at the annual meeting of the American Association for Cancer Research.

Overall, the numbers to date show a clear trend: The incidence of and mortality from CRC are higher among Black patients than other populations. However, the extent to which genetic difference plays a role in these disparities remains unclear.

In the current study, researchers from Memorial Sloan Kettering (MSK) Cancer Center in New York explored how germline and somatic genomic alterations differ among patients of African ancestry, in comparison with those of European and other heritage, and how those differences might influence CRC outcomes.

Lead author Henry Walch, MS, a computational biologist at MSK, and colleagues compared genomic profiles among nearly 3,800 patients with CRC who were treated at MSK from 2014 to 2022. Patients in the study were classified by genetic ancestry as European (3,201 patients), African (236 patients), East Asian (253 patients), and South Asian (89 patients).

Tumor and normal tissues from the patients underwent next-generation DNA sequencing with a panel that covers 505 cancer-associated genes.

An analysis of overall survival by genetic ancestry confirmed findings from other studies: Overall survival was significantly worse among patients of African ancestry than among those of other groups (median 45.7 vs. 67.1 months).

The investigators used a precision oncology knowledge base (OncoKB) to assign levels of therapeutic actionability for each genomic alteration that was identified. The highest assigned value was for drugs that have been approved by the U.S. Food and Drug Administration and that target FDA-recognized biomarkers. The lowest value was assigned to biomarkers for which there was “compelling biological evidence” that the particular biomarker predicted response to a drug.

The team found that the percentage of patients who qualified for immunotherapy on the basis of microsatellite instability or high tumor mutational burden was significantly lower among patients of African heritage, compared with those of European heritage (13.5% vs. 20.4%; P = .008).

Compared with those of European ancestry, patients of African ancestry had significantly fewer actionable alterations (5.6% vs. 11.2%; P = .01). This difference was largely driven by the lack of targetable BRAF mutations (1.8% vs. 5.0%).

Mutations in APC, the most frequently altered gene in CRC, are typically associated with cancer outcomes, but the authors found that overall survival was similar for patients of African heritage regardless of whether they had altered or wild-type APC (median overall survival, 45.0 months for altered APC vs. 45.9 months for wild-type APC; P = .91). However, a significant association between APC status and overall survival was observed for patients of European ancestry (median, 64.6 months for altered APC vs. 45.6 months for wild-type APC; P < .0001).

Analyses that accounted for sex, age, primary tumor location, and stage at diagnosis also showed an association between APC status and overall survival for patients of European heritage (hazard ratio, 0.64), but not for patients of African heritage (HR, 0.74, P = .492).

Mr. Walch noted that a limitation of the study is that information regarding comprehensive treatment, environmental exposures, lifestyle, and socioeconomic factors was not available for the analysis but that these elements likely play an important role in patient outcomes.

“This is a complex problem involving many unseen factors, and the genomic landscape is a piece of a much larger puzzle,” said Mr. Walch. He noted that future studies will incorporate these factors into the models “with the ultimate goal of identifying opportunities to intervene and improve outcomes.”

There have been increases in suspected suicidal cannabis exposures reported to U.S. poison control centers over the past 13 years. The increases were notable both during and after the pandemic and were highest among children and female persons.

Investigators examined closed cases of cannabis-related human exposures that were coded as intentional-suspected suicidal.

Of note, there was a statistically significant increase in cannabis poisonings in young children (5-13 years) in 2021, during the pandemic, compared with 2019, a prepandemic year (3.1% vs. 1.3%; P < .001), the researchers report.

“This may speak to both increased access to cannabis as well as poor mental health status during the pandemic period,” study investigator Tracy Klein, PhD, assistant director, Center for Cannabis Policy, Research and Outreach, Washington State University Vancouver, Mount Vista, said in an interview.

The study was published online  in JAMA Network Open.

Reports of intentional poisonings with cannabis increased by roughly 17% annually over the study period. Most cases occurred in recent years and involved individuals aged 14-64 years. Nearly all (96.5%) cases involved more than one substance.

“The resemblance of cannabis edibles, implicated in the majority of poisonings to candy, vitamins, and food products, is a risk to patients across the life span who may not fully understand what they are consuming or how potent it is,” Dr. Klein said in an interview.

Overall, nearly 1 in 10 exposures resulted in death or other major outcomes (life-threatening outcomes or outcomes involving major residual disability or disfigurement). For older adults, 19.4% of exposures led to death or other major harm.

“Elderly patients may also have comorbid conditions and polypharmacy, which contributes to their much more serious outcomes from cannabis poisoning,” Dr. Klein said.

The researchers caution that, owing to the cross-sectional nature of the data, they could not identify a causal association between cannabis use and suicide attempt.

With more states legalizing cannabis use by adults, increases in cannabis use will likely persist.

“It is important to further examine the suspected association between cannabis use and suicidal behaviors and how risks can be prevented or mitigated,” the researchers note.

Dr. Klein encourages health care providers to ask patients whether they are using cannabis and how they obtain and store it.

“As with all medications and substances, storage is a key safety issue that is elicited during a careful history,” said Dr. Klein.

Support for the study was provided in part by funds provided for medical and biological research by the State of Washington Initiative Measure No. 171. Dr. Klein has disclosed no relevant financial relationships.

Systemic therapy prior to surgery has been slow to catch on in the treatment of patients with resectable non–small cell lung cancer (NSCLC), primarily out of concern that neoadjuvant therapy could delay surgery or render patients ineligible for resection.

That may change, however, in light of new data from the phase 3 AEGEAN trial.

AEGEAN showed that neoadjuvant immunotherapy with durvalumab (Imfinzi) and chemotherapy followed by adjuvant durvalumab was associated with significant improvements in pathologic complete response rates and event-free survival, compared with neoadjuvant placebo plus chemotherapy followed by adjuvant placebo, and it did not affect patients’ ability to undergo surgery.

The event-free survival benefit among patients who received durvalumab translated to a 32% reduction in the risk of recurrence, recurrence precluding definitive surgery, or death, John V. Heymach, MD, reported in an oral abstract session at the annual meeting of the American Association for Cancer Research.

“Perioperative durvalumab plus neoadjuvant chemotherapy is a potential new treatment for patients with resectable non–small cell lung cancer,” said Dr. Heymach, chair of thoracic/head and neck medical oncology at the University of Texas MD Anderson Cancer Center in Houston.

The AEGEAN findings confirm the benefits of neoadjuvant immunotherapy that were first seen on a large scale in the Checkmate 816 study, which was reported at last year’s AACR annual meeting.

In Checkmate 816, adding the immune checkpoint inhibitor nivolumab to chemotherapy in the neoadjuvant setting resulted in significantly longer event-free survival and a 14-fold greater likelihood of a pathologic complete response compared with chemotherapy alone.

“I’m impressed by the fact that we now have a second study that shows the benefits of immunotherapy in the neoadjuvant setting, along with several adjuvant studies,” the invited discussant, Roy S. Herbst, MD, PhD, deputy director of the Yale Cancer Center, New Haven, Conn., said in an interview. “There’s no doubt that in early lung cancer, resectable disease, immunotherapy is part of the equation.”

For the current study, Dr. Heymach and colleagues recruited 802 patients from 222 sites in North and South America, Europe, and Asia. The patients had NSCLC and were treatment-naive, regardless of programmed cell death–ligand-1 (PD-L1) expression.

After excluding patients with targetable EGFR/ALK alterations, the team randomly allocated 740 patients who had good performance status (ECOG 0 or 1) to receive either neoadjuvant chemoimmunotherapy plus adjuvant immunotherapy or neoadjuvant chemotherapy alone. Overall, 77.6% of patients in the treatment arm and 76.7% of patients in the placebo arm underwent surgery following neoadjuvant therapy.

At the trial’s first planned interim analysis, for patients assigned to preoperative durvalumab plus platinum-based chemotherapy and postoperative durvalumab, the 12-month event-free survival rate was 73.4%, compared with 64.5% for patients who received chemotherapy alone before and placebo after surgery (stratified P = .003902).

The other endpoint, pathologic complete response, was observed in 17.2% of patients in the durvalumab arm, vs. 4.3% in the control arm – a 13% difference (P = .000036). Major pathologic responses, a secondary efficacy endpoint, were seen in 33.3% and 12.3% of patients, respectively.

The benefits of durvalumab were consistent across all subgroups, including those based on age at randomization, sex, performance status, race, smoking, histology (squamous vs. nonsquamous), disease stage, baseline PD-L1 expression, and planned neoadjuvant agent.

The safety profile of durvalumab plus chemotherapy was manageable, and the addition of durvalumab did not affect patients’ ability to complete four cycles of neoadjuvant chemotherapy, Dr. Heymach said.

Are these data practice changing?

Dr. Herbst gave a “resounding ‘Yes.’ “

But while the AEGEAN protocol represents a new standard of care, it can’t yet be labeled the standard of care, Dr. Herbst explained.

Dr. Herbst emphasized that, because this regimen was not compared against the current standard of care, it’s “impossible to determine” whether this is indeed the new standard.

“The data are early, and additional maturity is needed to better understand the benefit of the extra adjuvant therapy, and we’ll await the survival results,” he said.

It will also be important to analyze why some patients have only minor responses with the addition of durvalumab and whether there are resistance mechanisms at play for these patients. That would be a great setting “to start to test new therapies in a personalized way,” Dr. Herbst said.

Dr. Heymach and Dr. Herbst disclosed ties to AstraZeneca, which funded the study.

An unusual cause of ischemic stroke – the presence of structural bone and cartilage anomalies which cause mechanical stress to arteries supplying the brain – has been highlighted in a new case series.

These so-called “bony” strokes constitute a possible cause of recurrent ischemia in the same vascular territory as previous episodes, note the authors, led by Johanna Haertl, MD, Technical University of Munich.

“In patients with recurrent strokes in one vascular territory the presence of a symptomatic anatomic bone or cartilage anomaly may be considered as a differential diagnosis after sufficient exclusion of competing etiologies of an ischemic stroke,” they conclude.

“Due to the possibly high risk of stroke recurrence and potentially causative treatment options, bony strokes seem to be highly relevant for clinical practice,” they add.

The study was published online in the journal Stroke.

In their report, investigators explain that diagnosis of a bony stroke is based on a combination of imaging devices including CT, MRI, angiography, and sonography of brain-supplying vessels.

In addition to conventional static imaging, dynamic imaging modalities with the patients’ head in a fixed rotation or reclination has been shown to be useful as this enables the detection of a compressive effect on brain-supplying arteries caused by head movement.

They note that these bony strokes have been described previously – mainly as single case reports or small case series – but a systematic evaluation of each anatomical type of bony stroke is currently lacking.

For the current paper, the authors describe the identification and therapeutic workup of six patients with a bony stroke among 4,200 patients with ischemic stroke treated from January 2017 to March 2022 at their comprehensive stroke care center, constituting an incidence of 0.14%.

But they caution, “Given our retrospective study design, the method of patient acquisition, and the lack of systematic evaluation of bony strokes during acute stroke treatment, epidemiologic conclusions can be drawn only very carefully.”

In each of these six cases, the recurrent stroke was found to be caused by large-artery embolism from mechanical stress by bone or cartilage anomalies on arteries supplying the brain.

“Our case series aims to raise awareness for the rare entity of bony strokes, emphasizing the necessity to evaluate structural bone or cartilage lesions as a possible cause of ischemic stroke in patients with stroke recurrence of unknown cause in one vascular territory. We further aim on highlighting individual diagnostic and therapeutic options,” they state.

They note that it has previously been suggested that ischemic strokes based on bone or cartilage anomalies are more common in the relatively young patients with stroke, which is in line with their current patient data (mean age, 55 years), but this may reflect a selection bias.

A medical history with an association between changes in the head position and the occurrence of ischemic stroke may also raise awareness of the possibility of a bony stroke.

The authors outline treatment options for bony stroke, which they describe as diverse: They include conservative treatment, endovascular stenting, occlusion of the affected vessel, surgical bypass, and bone/cartilage removal.

From a pathophysiologic point of view, it seems reasonable to eliminate a causative lesion by surgical removal of the mechanical stressor, they note.

In cases of vascular stenting, they caution that the remainder of the mechanical stressor may provoke stent fracture and recurrent stroke, which occurred in two of their patients, a situation that may be observed more often in the future with the increasing use of vascular stenting.

The authors report that, compared with annual stroke rates in atrial fibrillation patients, stroke recurrence in this patient cohort ahead of definite treatment was high (cumulative 2.14 strokes per year). And as no patient had further ischemia after treatment, they argue that diagnosis and appropriate treatment of bony stroke may reduce or even eliminate the risk for future stroke recurrence.

They propose that for the diagnosis an exact medical history, with emphasis on a possible change of head position at the onset of stroke symptoms, is useful.  

Furthermore, previously acquired diagnostic scans including CT or MRI may be evaluated for a symptomatic vessel-bone or cartilage contact. Then, the additional application of dynamic imaging modalities, including dynamic ultrasound of brain-supplying vessels and CT-angiography, may be discussed.

“An appropriate diagnosis and the evaluation of individual and interdisciplinary treatment options seem crucial to prevent recurrent ischemic strokes. Future prospective trials seem mandatory to optimize patient care,” they conclude.

The study had no specific funding. Coauthor Jan S. Kirschke, MD, received research support from the German Research Foundation, Bonescreen, H2020 European Research Council, and Philips. The other authors report no relevant financial relationships.

An unusual cause of ischemic stroke – the presence of structural bone and cartilage anomalies which cause mechanical stress to arteries supplying the brain – has been highlighted in a new case series.

These so-called “bony” strokes constitute a possible cause of recurrent ischemia in the same vascular territory as previous episodes, note the authors, led by Johanna Haertl, MD, Technical University of Munich.

“In patients with recurrent strokes in one vascular territory the presence of a symptomatic anatomic bone or cartilage anomaly may be considered as a differential diagnosis after sufficient exclusion of competing etiologies of an ischemic stroke,” they conclude.

“Due to the possibly high risk of stroke recurrence and potentially causative treatment options, bony strokes seem to be highly relevant for clinical practice,” they add.

The study was published online in the journal Stroke.

In their report, investigators explain that diagnosis of a bony stroke is based on a combination of imaging devices including CT, MRI, angiography, and sonography of brain-supplying vessels.

In addition to conventional static imaging, dynamic imaging modalities with the patients’ head in a fixed rotation or reclination has been shown to be useful as this enables the detection of a compressive effect on brain-supplying arteries caused by head movement.

They note that these bony strokes have been described previously – mainly as single case reports or small case series – but a systematic evaluation of each anatomical type of bony stroke is currently lacking.

For the current paper, the authors describe the identification and therapeutic workup of six patients with a bony stroke among 4,200 patients with ischemic stroke treated from January 2017 to March 2022 at their comprehensive stroke care center, constituting an incidence of 0.14%.

But they caution, “Given our retrospective study design, the method of patient acquisition, and the lack of systematic evaluation of bony strokes during acute stroke treatment, epidemiologic conclusions can be drawn only very carefully.”

In each of these six cases, the recurrent stroke was found to be caused by large-artery embolism from mechanical stress by bone or cartilage anomalies on arteries supplying the brain.

“Our case series aims to raise awareness for the rare entity of bony strokes, emphasizing the necessity to evaluate structural bone or cartilage lesions as a possible cause of ischemic stroke in patients with stroke recurrence of unknown cause in one vascular territory. We further aim on highlighting individual diagnostic and therapeutic options,” they state.

When weighing medical schools, Hannah Gewaid admits that she kept the annual rankings from U.S. News & World Report in mind. “If I could get into a school of higher prestige, then I could have better odds for a good residency placement,” the pre-med student at the University of California, San Diego, told this news organization.

Although Ms. Gewaid considered other factors, she ultimately chose the highest-ranked medical school to which she was accepted: Rocky Vista University, Ivins, Utah. But it was the school’s environment that appealed to her most, she said. “Medical school can be pretty cut-throat, and I felt like the community at Rocky Vista was supportive. They also have one of the highest pass rates for boards in the nation, so it felt like the right combination for me.”

Likewise, Ramie Fathy, MD, a PGY1 internal medicine resident at Pennsylvania Hospital, Philadelphia, considered the report’s rankings when applying to medical schools. He chose the Perelman School of Medicine at the University of Pennsylvania, which ranked fifth in the nation at the time, and graduated a year ago.

In January, Harvard Medical School pulled out of the popular U.S. News rankings that many students use to guide their application decisions. Soon afterwards, other top-ranked medical schools – Columbia and Stanford – dropped out, setting off a spate of hopeful medical students and physicians questioning the value of the rankings and prospective students’ reliance on them.

Although Dr. Fathy doesn’t regret selecting Perelman before it joined the list of exiting schools, he wonders if he was shortsighted using the rankings as criteria. “It’s hard to know what makes a school unique from others, and the rankings serve as a metric to guide you,” he said. “But in the end, it’s not a reliable or reflective way to judge a school.”

Dr. Fathy said he is proud that Perelman opted out of the rankings: “I think it will help ensure that they prioritize what is best for the students and the quality of their training, rather than aspects that are relevant to rankings but don’t translate to a better overall student experience.”

Dr. Fathy’s viewpoint seems to be shared by the medical schools that announced they will no longer participate in the U.S. News rankings. The Association of American Medical Colleges recently reported that more than a dozen of the top 20 medical schools in the 2023 report have publicly exited the rankings.

USNWR’s chairman and CEO Eric Gertler said in a prepared statement that students turn to the rankings for help in making a key career decision in the face of competitive admissions and high tuition costs.

“We know that comparing diverse academic institutions across a common data set is challenging, and that is why we have consistently stated that the rankings should be one component in a prospective student’s decision-making process.”

The schools’ reasons for exiting vary. In Harvard’s case, Dean George Q. Daley, MD, PhD, said in a statement that the rankings don’t align with the school’s high standards of the school’s medical education programs.

Critics of the rankings say they rely too much on the grades and test scores of accepted students, AAMC reported. Stanford Dean, Lloyd Minor, MD, said the rankings fail to “capture the full extent of what makes an exceptional learning environment.” A school’s mission, curriculum, and other metrics should also be used to judge educational value, he said.

Medical schools that publicly announced their decisions to withdraw from the rankings also pointed to the extensive time and resources needed to gather data to submit to USNWR, rise in the standings, and remain at the top.

Bryan Carmody, MD, a Norfolk, Va.-based pediatric nephrologist and pediatrics professor known for his medical school commentaries, said in an interview that he doesn’t see the value of the rankings. “If you look at the data and factors the report collects, it has almost no impact on the day-to-day experience and quality of the medical school. It doesn’t assess meaningful educational outputs.”

Using MCAT scores and the GPAs of incoming students is irrelevant to the value the school can provide a student, Dr. Carmody said.

“The stated idea of the rankings is to measure quality, but in reality, it’s to maintain a certain hierarchy,” he said. “The content of the MCAT is only peripherally relevant. Real patients don’t come in as a multiple-choice question.”

The withdrawal of Harvard – which held the top ranking – put the report’s shortcomings in the spotlight, Dr. Carmody said. But Harvard wasn’t the first to pull out. In 2016, the Uniformed Services University in Maryland exited the rankings. Some schools chose never to participate, including most Historically Black Colleges and Universities, as well as osteopathic medical schools.

Given the ripple effect of high-ranking schools like Harvard pulling out of the rankings, prospective students are left to find other criteria to measure their future med schools.
 

Weighing other factors

If he could apply again, Dr. Fathy said he has the experience to know he wouldn’t have put as much weight in the U.S. News rankings. “At the time I was applying, it was hard to understand exactly what the rankings stood for,” he said. “I thought maybe a higher ranking meant better research opportunities and better connections. It’s hard to let go of the prestige relative to it all.”

His final two options had been Penn or Stanford. “Penn was the better choice for me, not because of its rankings, but because I had unique mentors and research opportunities there, and also because I had a scholarship,” he said. “I also had no family on the West Coast, which would have made a difference had I chosen Stanford.”

Dr. Fathy is happy the rankings have lost some of their prestige.

“I’m hoping that as schools pull out, it will demonstrate to applicants that the rankings aren’t where they should focus,” he said. “I also hope that down the line, it will prevent the name of a school from being such a big factor in residency applications.”

Dr. Fathy added that applying to residency programs has been an inequitable process, as institutions seem to judge applicants based on where they went to medical school. “When you look at the match lists, I believe programs put preference on students coming out of higher-ranking institutions,” he said.

Ahmed Mukhtar Ahmed, MPP, MSc, who will graduate soon from Harvard Medical School, said he hopes that the withdrawals from the ranking system will benefit future students. His initial choice of Harvard wasn’t the result of the rankings, he said. His family came from Somalia in 1996. “My mom sacrificed so much for me to get where I am, and when I was choosing a school, Harvard was the only name she recognized. It meant so much for her that I was accepted here.”

Beyond the emotional tie-in, however, Mr. Ahmed found Harvard to be the right fit for other reasons. “There’s so much opportunity here for someone with a focus on public health, and it has served me well.”

Still, Mr. Ahmed was not ignorant of the rankings. “I don’t know too many students who didn’t have their fingers on the pulse of the rankings,” he said. “There’s awareness that it’s not a good metric, but when applying to residencies, they keep in mind where you went to med school. So, we all have it in the back of our minds, for better or worse.”

Like Dr. Fathy, Mr. Ahmed can see the cracks in the ranking system. “I think the exodus from the rankings is good for applicants and also for the landscape of institutions, in general,” he said. “There’s nothing that says the number-one school is the best school for you.”

Mr. Ahmed points to other criteria, including financing opportunities, when judging a prospective school. “Talk to students and ask about how responsive administration is should a concern pop up,” he said. “Are they invested in student well-being? Also look at the diversity of institutions and experiences you will have. That’s something I didn’t appreciate until I was a student. I learned new things from the different hospitals I rotated through.”
 

What the future holds

Dr. Carmody recommends that students determine what information about a school matters to them. “What is their residency placement like, for instance? Keep in mind that most schools don’t convey this entirely truthfully, but it’s a measurement.”

Mr. Ahmed points to the Medical School Admission Requirements database compiled by the AAMC. “Look in the database to filter out where you should apply without the numbers attached to it,” he said. “Look at the faculty-to-student ratio, how much debt you might have to take on, and what housing is like, for instance. We should move toward a weighing system like that, rather than rankings.”

If the withdrawals of medical schools eventually lead to the demise of the rankings, Dr. Carmody noted the downsides. “There’s some concern that this will hurt pre-med students because it was the one place to find a certain amount of credible, objective data. There’s a ring of truth to that and a worry that schools won’t provide data in any sort of standardized way for an apples-to-apples comparison.”

It would also take time – probably as much as a decade – for the legacy of the U.S. News rankings to completely disappear, according to Dr. Carmody. Dr. Fathy agrees. “The rankings are ingrained on so many levels,” he said. “The better the ranking, the better the funding, so it’s self-reinforcing.”

In the future, other factors should guide students’ decision-making, including distance from family and friends, available research opportunities, and whether students are happy at the school, Dr. Fathy said. “There are so many experiential points to consider that go beyond the flawed ranking system.”

“I’m hoping that as schools pull out, it will demonstrate to applicants that the rankings aren’t where they should focus,” he said. “I also hope that down the line, it will prevent the name of a school from being such a big factor in residency applications.”

Dr. Fathy added that applying to residency programs has been an inequitable process, as institutions seem to judge applicants based on where they went to medical school. “When you look at the match lists, I believe programs put preference on students coming out of higher-ranking institutions,” he said.

Ahmed Mukhtar Ahmed, MPP, MSc, who will graduate soon from Harvard Medical School, said he hopes that the withdrawals from the ranking system will benefit future students. His initial choice of Harvard wasn’t the result of the rankings, he said. His family came from Somalia in 1996. “My mom sacrificed so much for me to get where I am, and when I was choosing a school, Harvard was the only name she recognized. It meant so much for her that I was accepted here.”

Beyond the emotional tie-in, however, Mr. Ahmed found Harvard to be the right fit for other reasons. “There’s so much opportunity here for someone with a focus on public health, and it has served me well.”

Still, Mr. Ahmed was not ignorant of the rankings. “I don’t know too many students who didn’t have their fingers on the pulse of the rankings,” he said. “There’s awareness that it’s not a good metric, but when applying to residencies, they keep in mind where you went to med school. So, we all have it in the back of our minds, for better or worse.”

Like Dr. Fathy, Mr. Ahmed can see the cracks in the ranking system. “I think the exodus from the rankings is good for applicants and also for the landscape of institutions, in general,” he said. “There’s nothing that says the number-one school is the best school for you.”

Mr. Ahmed points to other criteria, including financing opportunities, when judging a prospective school. “Talk to students and ask about how responsive administration is should a concern pop up,” he said. “Are they invested in student well-being? Also look at the diversity of institutions and experiences you will have. That’s something I didn’t appreciate until I was a student. I learned new things from the different hospitals I rotated through.”
 

What the future holds

Dr. Carmody recommends that students determine what information about a school matters to them. “What is their residency placement like, for instance? Keep in mind that most schools don’t convey this entirely truthfully, but it’s a measurement.”

Mr. Ahmed points to the Medical School Admission Requirements database compiled by the AAMC. “Look in the database to filter out where you should apply without the numbers attached to it,” he said. “Look at the faculty-to-student ratio, how much debt you might have to take on, and what housing is like, for instance. We should move toward a weighing system like that, rather than rankings.”

If the withdrawals of medical schools eventually lead to the demise of the rankings, Dr. Carmody noted the downsides. “There’s some concern that this will hurt pre-med students because it was the one place to find a certain amount of credible, objective data. There’s a ring of truth to that and a worry that schools won’t provide data in any sort of standardized way for an apples-to-apples comparison.”

It would also take time – probably as much as a decade – for the legacy of the U.S. News rankings to completely disappear, according to Dr. Carmody. Dr. Fathy agrees. “The rankings are ingrained on so many levels,” he said. “The better the ranking, the better the funding, so it’s self-reinforcing.”

In the future, other factors should guide students’ decision-making, including distance from family and friends, available research opportunities, and whether students are happy at the school, Dr. Fathy said. “There are so many experiential points to consider that go beyond the flawed ranking system.”
