No new safety signals reported for pembrolizumab as kidney cancer treatment

Article Type
Changed

 

A new analysis of KEYNOTE-564 demonstrates that pembrolizumab continues to show consistent and clinically meaningful improvement in disease-free survival for patients at high risk of a renal cell carcinoma recurrence.

The updated analysis was presented at the American Society of Clinical Oncology Genitourinary Cancers Symposium.

The study, which was led by Toni K. Choueiri, MD, director of the Lank Center for Genitourinary Oncology at Dana-Farber Cancer Institute, Boston, found no increase in high-grade, or other, adverse events with 30 months of follow-up.

Pembrolizumab (Keytruda, Merck) is approved by the Food and Drug Administration in combination with axitinib, as a first-line treatment for patients with advanced renal cell carcinoma (RCC). The combination is also recommended by the European Society for Medical Oncology for advanced RCC.

KEYNOTE-564 is a phase 3, double-blind, multicenter trial of pembrolizumab versus placebo after surgery in participants with renal cell carcinoma. In previously presented interim KEYNOTE-564 results, the primary endpoint of disease-free survival for adjuvant pembrolizumab versus placebo was met in the intent-to-treat population (hazard ratio, 0.68; 95% confidence interval, 0.53-0.87; P = .001).

KEYNOTE-564 includes 994 patients (mean age, 60 years; 71% male) with confirmed clear cell RCC who were either intermediate to high risk, high risk, or M1 with no evidence of disease after surgery. All patients had surgery 12 or fewer weeks prior to randomization.

At 30.1 months, the disease-free survival difference in the intent-to-treat population between pembrolizumab and placebo at 78.3% versus 67.3% had a HR of 0.63 (95% CI, 0.50-0.80; nominal P < .0001), greater than the 77.3% versus 68.1% difference at 24.1 months (hazard ratio, 0.68, 95% CI, 0.53-0.87; P = .001).

Analysis of disease-free survival by recurrence risk subgroups showed an increasing benefit with increasing risk. In the intermediate- to high-risk group, the 24-month rates were 81.1% and 72.0% for pembrolizumab and placebo, respectively (HR, 0.68; 95% CI, 0.52-0.89). In the high-risk group, the 24-month rates were 48.7% and 35.4%, respectively (HR, 0.60; 95% CI, 0.33-1.10). In the M1 NED group, the rates were 78.4% and 37.9% for pembrolizumab and placebo, respectively (HR, 0.28; 95% CI, 0.12-0.66).

During a discussion about the presentation, Daniel M Geynisman, MD, of Fox Chase Cancer Center, Philadelphia, pointed to the respective absolute differences between pembrolizumab and placebo of 9% in the intermediate- to high-risk group, 13% in the high-risk group, and a “whopping difference of 41% in the M1 NED group,” but underscored that the M1 NED population represents only a small part of the trial population (5.8%). The same relationship was evident among sarcomatoid status subgroups, with 24-month absolute differences of 10.1% favoring pembrolizumab (HR, 0.63) with sarcomatoid features absent and 19.8% (HR, 0.54) when they were present.

Overall survival estimates showed an increasing benefit for pembrolizumab versus placebo (96.6% vs. 93.5%; HR, 0.54) at 24.1 months (96.2% vs. 93.8%, HR, 0.52), but this wasn’t statistically significance because the data collection was incomplete.

Between 24.1 months and 30.1 months, rates of treatment-related adverse events remained the same at 79.1% for pembrolizumab and 53.4% for placebo, with a treatment-related discontinuations in the pembrolizumab group at 17.6% and 18.6% at 24.1 and 30.1 months, respectively.

The study was funded by Merck Sharp & Dohme.

C. difficile vaccine: Pfizer’s phase 3 CLOVER trial shows mixed results

There’s mixed news from Pfizer on results from their CLOVER trial (CLOstridium difficile Vaccine Efficacy TRial), a phase 3 study involving 17,500 adults aged 50 and older that evaluated their candidate vaccine (PF-06425090) against Clostridioides difficile (C. diff) for the prevention of C. diff. infection (CDI).

The bad news is that the trial didn’t meet its efficacy endpoint – the prevention of primary CDI. According to a Pfizer press release, “Vaccine efficacy under the primary endpoint was 31% (96.4%, confidence interval -38.7, 66.6) following the third dose and 28.6% (96.4%, CI -28.4, 61.0) following the second dose. For all CDI cases recorded at 14 days post dose 3, vaccine efficacy was 49%, 47%, and 31% up to 12 months, 24 months, and at final analysis, respectively.”

This news organization requested an interview with a Pfizer spokesperson, but the company declined to comment further.

The good news is that the vaccine did meet its secondary endpoint. There were no cases of CDI requiring medical attention among vaccine recipients; by comparison, there were 11 cases among those who received placebo.

The Centers for Disease Control and Prevention classifies C. diff with other antimicrobial resistance “threat” organisms, as the two often go hand in hand. Their 2019 report noted that in 2017, 223,900 people in the United States required hospitalization for CDI, and at least 12,800 died. C. diff is the most common cause of health care-associated infection and increasingly occurs outside of acute care hospitals. Age older than 65 is a risk factor for disease. And at least 20% of patients experience recurrence.

The trial enrolled people older than 50 who were at higher risk of CDI because of having received antibiotics within the previous 12 weeks or because they were likely to have contact with health care systems. They received three doses of an investigational vaccine containing detoxified toxins A and B. These are the principal virulence factors produced by C. diff. Doses were given at 0, 1, and 6 months.

This news organization asked C. diff specialist David Aronoff, MD, chair of the department of medicine at Indiana University, for comment. Dr. Aronoff was not involved in the Pfizer clinical trials. He told this news organization via email, “Given the very low number of cases, I am impressed, from the limited data that have been made available, that the vaccine appears to have efficacy of around 50% for reducing CDI and, importantly, might reduce the severity of disease significantly, possibly preventing hospitalizations or worse clinical outcomes. It is unclear if the vaccine reduces the risk of recurrent CDI, but that would be a strong finding if true. I think we need to see these data after being subject to peer review, to better define its potential role in preventing CDI on a larger scale.”

Asked about the numbers needed to treat and cost-effectiveness of treatment, Dr. Aronoff added, “It is not clear how many people would need to receive the vaccine to prevent one hospitalization from CDI, or one death, or one case. Because the study groups had fewer episodes of CDI than anticipated, it watered down the power of this investigation to provide definitive answers regarding its true efficacy.”

Dr. Aronoff concluded, “All things considered, I am a cup half-full type of person on these topline results, since there are indications of reducing disease incidence and severity. We can build on these results.”

Dr. Aronoff had a basic science C. diff research grant from Pfizer in 2018-2019 that was not related to vaccines or therapeutics.

New carcinogens added to toxicology list

Article Type
Changed

From environmental tobacco smoke to ultraviolet (UV) radiation, diesel exhaust particulates, lead, and now, chronic infection with Helicobacter pylori (H pylori) —the Report on Carcinogens has regularly updated the list of substances known or “reasonably anticipated” to cause cancer.

The 15th report, which is prepared by the National Toxicology Program (NTP) for the Department of Health and Human Services, has 8 new entries, bringing the number of human carcinogens (eg, metals, pesticides, and drugs) on the list to 256. (The first report, released in 1980, listed 26.) In addition to H. pylori infection, this edition adds the flame-retardant chemical antimony trioxide, and 6 haloacetic acids found as water disinfection byproducts.

In 1971, then-President Nixon declared “war on cancer” (the second leading cause of death in the United States) and signed the National Cancer Act. In 1978, Congress ordered the Report on Carcinogens, to educate the public and health professionals on potential environmental carcinogenic hazards.

Perhaps disheartening to know that even with 256 entries, the list probably understates the number of carcinogens humans and other creatures are exposed to. But things can change with time. Each list goes through a rigorous round of reviews. Sometimes substances are “delisted” after, for instance, litigation or new research. Saccharin, for example, was removed from the ninth edition. It was listed as “reasonably anticipated” in 1981, based on “sufficient evidence of carcinogenicity in experimental animals.” It was removed, however, after extensive review of decades of saccharin use determined that the data were not sufficient to meet current criteria. Further research had revealed, also, that the observed bladder tumors in rats arose from a mechanism not relevant to humans.

Other entries, such as the controversial listing of the cancer drug tamoxifen, walk a fine line between risk and benefit. Tamoxifen, first listed in the ninth report (and still in the 15th report), was included because studies revealed that it could increase the risk of uterine cancer in women. But there also was conclusive evidence that it may prevent or delay breast cancer in women who are at high risk.

Ultimately, the report’s authors make it clear that it is for informative value and guidance, not necessarily a dictate. As one report put it: “Personal decisions concerning voluntary exposures to carcinogenic agents need to be based on additional information that is beyond the scope” of the report.

“As the identification of carcinogens is a key step in cancer prevention,” said Rick Woychik, PhD, director of the National Institute of Environmental Health Sciences and NTP, “publication of the report represents an important government activity towards improving public health.”

In 1971, then-President Nixon declared “war on cancer” (the second leading cause of death in the United States) and signed the National Cancer Act. In 1978, Congress ordered the Report on Carcinogens, to educate the public and health professionals on potential environmental carcinogenic hazards.

Perhaps disheartening to know that even with 256 entries, the list probably understates the number of carcinogens humans and other creatures are exposed to. But things can change with time. Each list goes through a rigorous round of reviews. Sometimes substances are “delisted” after, for instance, litigation or new research. Saccharin, for example, was removed from the ninth edition. It was listed as “reasonably anticipated” in 1981, based on “sufficient evidence of carcinogenicity in experimental animals.” It was removed, however, after extensive review of decades of saccharin use determined that the data were not sufficient to meet current criteria. Further research had revealed, also, that the observed bladder tumors in rats arose from a mechanism not relevant to humans.

Other entries, such as the controversial listing of the cancer drug tamoxifen, walk a fine line between risk and benefit. Tamoxifen, first listed in the ninth report (and still in the 15th report), was included because studies revealed that it could increase the risk of uterine cancer in women. But there also was conclusive evidence that it may prevent or delay breast cancer in women who are at high risk.

Ultimately, the report’s authors make it clear that it is for informative value and guidance, not necessarily a dictate. As one report put it: “Personal decisions concerning voluntary exposures to carcinogenic agents need to be based on additional information that is beyond the scope” of the report.

“As the identification of carcinogens is a key step in cancer prevention,” said Rick Woychik, PhD, director of the National Institute of Environmental Health Sciences and NTP, “publication of the report represents an important government activity towards improving public health.”

Height an ‘overlooked risk factor’ for colorectal cancer?

Article Type
Changed

A new meta-analysis provides more evidence that taller people may be more likely than their shorter peers to develop colorectal cancer (CRC) or colon polyps.

“There are well-known modifiable dietary associations for colorectal cancer, such as processed red meats and smoking, but guidelines currently are fixated on family history, and height is clinically neglected when it comes to risk screening,” study investigator Gerard Mullin, MD, with Johns Hopkins University, Baltimore, said in a news release. This large study “builds on evidence that taller height is an overlooked risk factor and should be considered when evaluating and recommending patients for colorectal cancer screenings.”

The study was published online March 1 in Cancer Epidemiology, Biomarkers & Prevention.
 

The evidence: Height and cancer risk

Height has been actively studied as a potential nonmodifiable risk factor for a range of cancers, including CRC.

In one large prospective study of postmenopausal women, researchers found a modest but statistically significant positive association between height and risk for any cancer and for melanoma, multiple myeloma, and cancers of the thyroid, ovary, colorectum, and endometrium. 

A separate study found that tall men, especially those who are long-legged, may be at increased risk for prostate cancer, including high-grade tumors, relative to men of more modest stature.

However, the study authors point out, past studies have also produced mixed results, used inconsistent measures of height, and failed to include the risk of adenomas.  

In the current meta-analysis, the investigators included 47 international, observational studies involving 280,644 adults with CRC and 14,139 cases of colorectal adenoma.

Because the definition of tallness differs around the world, the researchers compared the highest versus the lowest height percentile of various study groups. The findings were adjusted for demographic, socioeconomic, behavioral, and other known risk factors for CRC.

Overall, the investigators found that the tallest individuals within the highest percentile of height had a 24% higher risk of developing CRC compared to the shortest individuals within the lowest percentile (hazard ratio [HR], 1.24; P < .001).

In addition, they found that every 10-cm increase (about 4 inches) in height was associated with a 14% increased risk of developing CRC (HR, 1.14; P < .001) and a 6% increased likelihood of adenomas (odds ratio [OR], 1.06; P = .03).

In the United States, the average height for men is 5 feet, 9 inches, and for women it is 5 feet, 4 inches, which means men who are 6 feet, 1 inch and women who are 5 feet, 8 inches or taller have a 14% increased risk of CRC and a 6% increased risk of adenomas, the researchers explained.

According to co–first author Elinor Zhou, MD, also with Johns Hopkins University, a potential explanation for this link “is that adult height correlates with body organ size. More active proliferation in organs of taller people could increase the possibility of mutations leading to malignant transformation.”

The study authors said more research is needed to identify particular subgroups of tall people at risk for CRC.

“For instance, tall athletes and individuals with inherited tallness, such as those with Marfan syndrome, could be screened earlier and the impact of height further explored,” Dr. Zhou said.

Plus, Dr. Zhou added, more studies are needed to “definitively say at what height you would need earlier colorectal cancer screening.”

The current study was supported by grants from Bloomberg Philanthropies, intramural funds, and the Johns Hopkins Cancer Center Support Grant. The authors declared no conflicts of interest.

Wake Forest Cancer Center director fired, advisory board resigns

Article Type
Changed

All 15 members of Wake Forest Baptist Comprehensive Cancer Center’s external advisory board (EAB) resigned on February 18 and withdrew their endorsement for renewal of the center’s National Cancer Institute comprehensive cancer center support grant.

The move was prompted by the abrupt firing of center director Boris Pasche, MD, PhD, on February 10, one day after NCI renewed a multimillion dollar grant.

The Cancer Letter broke the story and published the resignation letter from the EAB. It was signed by board chair Gerold Bepler, MD, PhD, CEO and director of the Karmanos Cancer Institute, Detroit, on behalf of the board.

The mass resignation of an EAB, a panel of outside experts that help shepherd cancer centers through the NCI grant process, is “highly unusual,” according to The Cancer Letter. It also raises concerns about the “immediate future” of Wake Forest’s cancer center, the publication added.

Numerous people involved with the situation did not respond or declined to comment when this news organization requested additional information and updates, including questions about the reason for Dr. Pasche’s termination; whether or not withdrawal of the endorsement puts Wake’s NCI designation in jeopardy; and if the EAB is being reconstituted.

A written statement from Wake Forest simply said that “the situation involving Dr. Pasche is an administrative decision. Various administrative changes occur regularly in organizations across the country. Dr. Pasche remains employed by Atrium Health Wake Forest Baptist. We are very grateful to Dr. Pasche for his years of service and many contributions to the mission and vision of our NCI-designated Comprehensive Cancer Center in Winston-Salem.”

Wake’s cancer center is in the process of combining with the Atrium Health Levine Cancer Center, which is not NCI-designated, following Atrium Health system’s recent acquisition of the Wake Forest Baptist Medical Center.

The NCI renewal notice, dated February 9, states that Dr. Pasche “and his leadership team have built a robust, transdisciplinary center that includes 140 scientists.”

Dr. Pasche was fired a day later.

The EAB resignation letter states that during Wake Forest’s recent NCI review process, “leadership gave their glowing endorsement of Dr. Pasche...This endorsement included unequivocal statements of support for Dr. Pasche’s oversight of the combined Atrium-Wake Forest cancer program.”

“What followed was his rapid dismissal after the...notice of award was issued, following a period during which the approach to integration was apparently being revisited,” Dr. Bepler said on behalf of the board.

“It is with sadness and dismay that we witnessed the change in approach by the institutional leadership towards” the merger, he wrote.

The Cancer Letter quotes an unnamed board member as saying, “EABs for cancer centers can only provide value to the center when there is openness and transparency in the process. In the absence of such, I believe the members felt that there was no further utility in providing guidance to the organization.”

The resignation letter was sent to the interim director of Wake’s cancer center, radiation oncologist William Blackstock, Jr, MD, and also copied to Atrium-Wake and NCI leadership.

The resignation letter endorsed Dr. Blackstock’s qualifications to run the center, and noted that as the board is reconstituted, “some of us would be honored to discuss participation...if there is unequivocal evidence from the health system’s senior management for support of a single, academically driven, comprehensive, and integrated cancer center.”

ESC suspension of Russia, Belarus societies sparks controversy

Article Type
Changed

The European Society of Cardiology has temporarily suspended membership of the cardiology societies in Russia and Belarus, provoking a heated discussion on whether medical organizations should become involved in politics.

“In the light of the continued aggression against Ukraine by the leaderships of the Russian Federation and Belarus, the European Society of Cardiology (ESC) has temporarily suspended the memberships of the Russian Society of Cardiology and the Belarussian Society of Cardiologists in the ESC,” the ESC statement reads.

“Individuals based in the Russian Federation or in Belarus are excluded from active participation in any ESC event or activity,” it states.

“The ESC very much regrets the effect this may have on individual Russian and Belarussian cardiologists and scientists, but the message to Russian and Belarussian leadership must be distinct and unequivocal,” it adds.

This action from the ESC has provoked a storm of heated discussions on the issue.

In a Twitter thread on the subject, Italian cardiologist Giuseppe Galati, MD, writes: “An astonishing decision by ESC that’s excluding all the Russian and Belarussian scientists from ESC congresses and activities. Treating doctors and scientists as [if] they are Putin and are responsible for the war.” 

Dr. Galati adds: “A strong message that brings us to 70 years ago. ESC is promoting exclusion and not inclusion and diversity.”

Another commentator on the thread says: “It is a very unfortunate decision. Science, medicine should not be involved in politics. We are colleagues gathering together during congresses to exchange information for the sake of our patients. Politics should not overshadow this.”

And another added: “I think most cardiologists from Russia will not be able to participate in the events anyway, since international payments will soon be impossible from Russia. But it is wrong to limit the rights of doctors because of their nationality.”

But others support the ESC’s stance. Polish cardiologist Blazej Michalski, MD, says: “I think it is [a] good decision. Russians if they do not actively support dictatorship of Putin, the silence is also an agreement.” He adds: “I am proud of ESC. They did what they were supposed to do.”

A Twitter poll started by Ali Elzieny, MD, a cardiologist from Boston, titled “Do you agree that ESC suspend membership of Russian Society of Cardiology?” as of March 8 had 1,300 votes, with 61% of respondents disagreeing with the ESC decision and 39% in favor.
 

Medical societies respond

Several other medical societies have issued communications appearing to disagree with the action by the ESC.

The American College of Cardiology issued a statement saying medicine should be above politics.

“The American College of Cardiology believes that patients come first, and now, more than ever, there is a need to rally around our members across the globe to ensure that they have the support and resources they need to care for their patients,” said ACC President Dipti Itchhaporia, MD.

“Medicine is above politics and ACC will not exclude any of our colleagues who are working toward a shared mission of improving heart health. The College has a long history of working across borders to improve heart health and remains committed to that now and in the future. The ACC continues to express its support and concern for our members in the Ukraine and the patients they are working to treat on the frontlines,” the ACC statement added.

The Tele-Cardiology Working Group of the International Society for Telemedicine & eHealth (ISFTEH) also issued a statement disagreeing with the action from the ESC.

“In light of recent events, the cardiology working group of the ISFTEH will not restrict access to its events to cardiologists with regards to their nationality, religious beliefs or other characteristics that may seem discriminatory. We believe medical information should be widely available for all, especially for those doctors that find themselves in difficulty,” it said.

The European Academy of Neurology (EAN) said: “EAN is looking at ways to give practical support to Ukrainian neurologists and healthcare professionals there. EAN is not considering suspension of any individual member based on country of residence or nationality or any National Society member.”

But one oncology professional group has also cut ties with Russia.

The international cancer specialist network, OncoAlert, issued a statement saying it has severed all cooperation with doctors in Russia as part of the Western sanctions.

“The OncoAlert Network is non-political, but we cannot stand idle and not take a stand against this aggression towards our Ukrainian friends & colleagues,” OncoAlert said, adding that it will be pulling out of all collaborations and congresses in Russia. That statement was also greeted with a barrage of criticism on Twitter, mainly from Russian users.

But others support the ESC’s stance. Polish cardiologist Blazej Michalski, MD, says: “I think it is [a] good decision. Russians if they do not actively support dictatorship of Putin, the silence is also an agreement.” He adds: “I am proud of ESC. They did what they were supposed to do.”

A Twitter poll started by Ali Elzieny, MD, a cardiologist from Boston, titled “Do you agree that ESC suspend membership of Russian Society of Cardiology?” as of March 8 had 1,300 votes, with 61% of respondents disagreeing with the ESC decision and 39% in favor.
 

Medical societies respond

Several other medical societies have issued communications appearing to disagree with the action by the ESC.

The American College of Cardiology issued a statement saying medicine should be above politics.

“The American College of Cardiology believes that patients come first, and now, more than ever, there is a need to rally around our members across the globe to ensure that they have the support and resources they need to care for their patients,” said ACC President Dipti Itchhaporia, MD.

“Medicine is above politics and ACC will not exclude any of our colleagues who are working toward a shared mission of improving heart health. The College has a long history of working across borders to improve heart health and remains committed to that now and in the future. The ACC continues to express its support and concern for our members in the Ukraine and the patients they are working to treat on the frontlines,” the ACC statement added.

The Tele-Cardiology Working Group of the International Society for Telemedicine & eHealth (ISFTEH) also issued a statement disagreeing with the action from the ESC.

“In light of recent events, the cardiology working group of the ISFTEH will not restrict access to its events to cardiologists with regards to their nationality, religious beliefs or other characteristics that may seem discriminatory. We believe medical information should be widely available for all, especially for those doctors that find themselves in difficulty,” it said.

The European Academy of Neurology (EAN) said: “EAN is looking at ways to give practical support to Ukrainian neurologists and healthcare professionals there. EAN is not considering suspension of any individual member based on country of residence or nationality or any National Society member.”

But one oncology professional group has also cut ties with Russia.

The international cancer specialist network, OncoAlert, issued a statement saying it has severed all cooperation with doctors in Russia as part of the Western sanctions.

“The OncoAlert Network is non-political, but we cannot stand idle and not take a stand against this aggression towards our Ukrainian friends & colleagues,” OncoAlert said, adding that it will be pulling out of all collaborations and congresses in Russia. That statement was also greeted with a barrage of criticism on Twitter, mainly from Russian users.

Mutation drives persistent Pseudomonas in COPD

Pseudomonas aeruginosa persisted in the airways of patients with chronic obstructive pulmonary disease (COPD), based on data from 23 patients over a 1-year period.

P. aeruginosa is cultured in as many as 20% of bacterial exacerbations and has been linked to increased morbidity and mortality in patients with COPD, wrote Josefin Eklöf, MD, of the University of Copenhagen and colleagues. However, its patterns and characteristics have not been well studied, and researchers proposed that P. aerunginosa persists in COPD patients in part because of genetic adaptations in the genes related to antibiotic resistance.

In a study published in Clinical Microbiology and Infection, the researchers identified 23 consecutive patients enrolled in an ongoing randomized clinical trial at four sites in Denmark between Jan. 2018 and Jan. 2020. Participants were randomized 1:1 to targeted antipseudomonal antibiotic treatment for 14 days (between visit day 1 and visit day 14) or no antipseudomonal treatment. Sputum samples were collected at baseline on day 1 and on days 14, 30, 60, 90, and 365.

The researchers sequenced isolates from 23 adult patients over 365 days of follow-up. The recurrence of P. aeruginosa occurred in 19 patients (83%) during this period. Ultimately, a total of 153 isolates were analyzed. The researchers found that each patient carried their own unique lineage, with the except of one patient in whom two distinct lineages were identified.

“Independent mutation of the same gene across multiple lineages may be the result of positive selection of adaptive mutations,” Dr. Eklöf and colleagues wrote. They found 38 genes for P. aeruginosa that were mutated in at least two lineages, which suggested adaptive mutations. Some of the more frequently mutated genes were those important to antibiotic resistance and chronic infections, the researchers said. Specifically, mutations occurred in 40 of 140 pathoadaptive genes, compared with 265 of 5,572 other genes (P < .001). In addition, the 24 total lineages carried 4-6 antibiotic resistance genes, and no evidence suggested that lineages acquired or lost these genes during carriage.

Overall, the results indicate that the recurrence of P. aeruginosa was caused by persistence of the same clonal lineage in each patient. “This pattern of persistence was associated with genetic adaptation related to phenotypes considered important for P. aeruginosa infections,” the researchers said.

The study findings were limited by the relatively small number of samples and isolates per sample, the follow-up of only 1 year, and the inability to account for mutations in the early stage because few patients were naive to P. aeruginosa at the start of the study, the researchers noted. However, the results were strengthened by the relatively large and well-defined study population and high rate of sampling compliance, they said.

Overall, “the findings warrant research to improve therapy, including trial data on possible clinical benefits of attempting antibiotic eradication of P. aeruginosa in this vulnerable group of patients,” they concluded.

The study was supported by the Independent Research Fund Denmark and the Research committee at Copenhagen University Hospital-Herlev and Gentofte Hospital. The researchers had no financial conflicts to disclose.

First ‘before-and-after’ COVID-19 brain imaging study shows structural changes

Article Type
Changed

 

Even mild cases of COVID-19 are associated with brain changes, including decreased gray matter, an overall reduction in brain volume, and cognitive decline, a new imaging study shows.

In the first study to use magnetic resonance brain imaging, before and after COVID-19, investigators found “greater reduction in grey matter thickness and tissue-contrast in the orbitofrontal cortex and parahippocampal gyrus, greater changes in markers of tissue damage in regions functionally connected to the primary olfactory cortex and greater reduction in global brain size.” However, the researchers urge caution when interpreting the findings.

Gwenaëlle Douaud, PhD, Wellcome Center for Integrative Neuroimaging, Nuffield Department of Clinical Neurosciences, University of Oxford, England, and colleagues describe these brain changes as “modest.”

“Whether these abnormal changes are the hallmark of the spread of the pathogenic effects in the brain, or of the virus itself, and whether these may prefigure a future vulnerability of the limbic system in particular, including memory, for these participants, remains to be investigated,” the researchers wrote.

The findings were published online March 7 in the journal Nature.
 

Gray matter loss

The investigators analyzed data from the UK Biobank, a large-scale biomedical database with genetic and health information for about 500,000 individuals living in the UK. They identified 785 adults aged 51-81 years who had undergone two brain MRIs about 3 years apart. Of these, 401 tested positive for SARS-CoV-2 before the second scan.

Participants also completed cognitive tests at the time of both scans.

Biobank centers use identical MRI scans and scanning methods, including six types of MRI scans, to image distinct regions of the brain and brain function. Results showed that although some loss of gray matter over time is normal, individuals who were infected with SARS-CoV-2 showed a 0.2% to 2% brain tissue loss in the parahippocampal gyrus, the orbitofrontal cortex, and the insula – all of which are largely involved in the sense of smell.

Participants who had contracted COVID-19 also showed a greater reduction in overall brain volume and a decrease in cognitive function.

Most of those with COVID-19 had only mild or moderate symptoms. However, the findings held even after the researchers excluded patients who had been hospitalized.
 

More research needed

“These findings might help explain why some people experience brain symptoms long after the acute infection,” Max Taquet, PhD, National Institute for Health Research Oxford Health BRC senior research fellow, University of Oxford, said in a press release.

Dr. Taquet, who was not a part of the study, noted the causes of these brain changes remain to be determined. Questions remain as to “whether they can be prevented or even reverted, as well as whether similar changes are observed in hospitalized patients,” children, younger adults, and minority groups.

“It is possible that these brain changes are not caused by COVID-19 but represent the natural progression of a disease that itself increased the risk of COVID-19,” Dr. Taquet said.

Other experts expressed concern over the findings and emphasized the need for more research.

“I am very concerned by the alarming use of language in the report with terms such as ‘neurodegenerative,’ “ Alan Carson, MD, professor of neuropsychiatry at the Center for Clinical Brain Sciences at the University of Edinburgh, Scotland, said in a press release. “The size and magnitude of brain changes found is very modest and such changes can be caused by a simple change in mental experience,” Dr. Carson said.

“What this study almost certainly shows is the impact, in terms of neural changes, of being disconnected from one’s sense of smell,” he added.

The study was funded by the Wellcome Trust Collaborative. Full financial conflict information for the study authors is included in the original article. Dr. Taquet has collaborated previously with some of the investigators.

MRI with mammogram reduces breast cancer mortality by more than 50% in high-risk women

Article Type
Changed

Among women with ATM, CHEK2, or PALB2 pathogenic variants, annual MRI screening beginning at age 30 or 35, followed by concomitant MRI and mammography at age 40, could significantly reduce breast cancer mortality, according to a new model.

Adjunct screening with MRI is already recommended among women with the BRCA1 or BRCA2 mutations. ATM, CHEK2, and PALB2 are the most common of a more recently discovered group of pathogenic variants that confer a moderate to high risk of breast cancer.

In a study published online Feb. 17, 2022, in JAMA Oncology, researchers used two simulation models and risk estimates from the Cancer Risk Estimates Related to Susceptibility Consortium to predict that MRI screening at age 35 would produce a 54.4%-57.6% reduction in breast cancer mortality, with an estimated 4,661-5,001 false positive screenings and 1,280-1,368 benign biopsies per 1,000 women. At age 30, the model predicted 55.4-59.5% reduction in risk, 5,075-5,415 false positives, and 1,439-1,528 benign biopsies. Annual mammography at age 40 alone could reduce risk by 36%-39%.

The false positives and benign biopsies represent cumulative lifetime results.

“We’ve known for a long time that mammography is less sensitive in younger women than in older women and, of course, when women have a genetic predisposition, we’re very concerned about early-onset cancer. We’ve also known that when you do MRI at the same time as mammography, you find a lot more cancers. [There are] more false positives, but there is clearly a greater yield of cancer in that setting, and the cancers are found earlier,” senior author Mark Robson, MD, said in an interview.

The model showed that mammography screening in women under 40 added no survival benefit, and led to additional false positives and benign biopsies.

“We know that MRI’s detection rate for cancers in a head-to-head comparison with mammography is extremely high, and so I’m not surprised that there was such a difference from a mammography strategy. What I was excited by is just how impactful the MRI screen was in terms of projected reduction in the risk of death. I thought that great,” said Dr. Robson, who is chief of the breast medicine service at Memorial Sloan Kettering Cancer Center, New York.

The balance of mortality reduction versus false positives and benign biopsies will need to be weighed by others. “We didn’t feel like we could make those judgments, but what we were presenting was for people who do make these kinds of policies. The reason that we said 30-35 years (for MRI initiation) is because at that point, the false positive versus life-years gained curve starts to plateau. For instance, when we look at strategies of starting MRI at 25, you we don’t get significantly more life years gained, but we do get more false positives,” Dr. Robson said.

The researchers did not conduct a former cost-benefit analysis for initiating MRI screening at age 30-35.

The study “reinforces the value of MRI for women with these variants that are really just entering the clinical consciousness, and affirms that we need to be doing that in young women to help prevent death from breast cancer. I also think that we need to look at really what mammogram is adding in young women and consider whether or not we really need it at the policy level,” he said.

The study was funded by the National Cancer Institute and the Breast Cancer Research Foundation. Dr. Robson has conducted clinical trials with AstraZeneca, Merck, and Pfizer.

“We know that MRI’s detection rate for cancers in a head-to-head comparison with mammography is extremely high, and so I’m not surprised that there was such a difference from a mammography strategy. What I was excited by is just how impactful the MRI screen was in terms of projected reduction in the risk of death. I thought that great,” said Dr. Robson, who is chief of the breast medicine service at Memorial Sloan Kettering Cancer Center, New York.

The balance of mortality reduction versus false positives and benign biopsies will need to be weighed by others. “We didn’t feel like we could make those judgments, but what we were presenting was for people who do make these kinds of policies. The reason that we said 30-35 years (for MRI initiation) is because at that point, the false positive versus life-years gained curve starts to plateau. For instance, when we look at strategies of starting MRI at 25, you we don’t get significantly more life years gained, but we do get more false positives,” Dr. Robson said.

The researchers did not conduct a former cost-benefit analysis for initiating MRI screening at age 30-35.

The study “reinforces the value of MRI for women with these variants that are really just entering the clinical consciousness, and affirms that we need to be doing that in young women to help prevent death from breast cancer. I also think that we need to look at really what mammogram is adding in young women and consider whether or not we really need it at the policy level,” he said.

The study was funded by the National Cancer Institute and the Breast Cancer Research Foundation. Dr. Robson has conducted clinical trials with AstraZeneca, Merck, and Pfizer.

Testicular cancer mortality rates dip for Hispanic men

Article Type
Changed

A study of testicular cancer mortality finds worse outcomes among Hispanic men, but better outcomes among Black men.

The findings were reported at the American Society of Clinical Oncology Genitourinary Cancers Symposium.

Incidence rates for testicular cancer in the United States have increased slowly in recent decades, said Anushka Ghosh, a clinical research coordinatory with Massachusetts General Hospital, Boston. Her analysis found mortality increases from 1999 to 2019 to be significantly greater among Hispanic men. The increase was 0.0019 per 100,000, compared with a 0.0003 per 100,000 decrease among non-Hispanic men (comparison P = .010).

Among Black men, testicular cancer–specific mortality rates declined by 0.0007 per 100,000, compared with a marginally significant increase of 0.0006 per 100,000 among White men (P =.049).

“Given that testicular cancer generally has a favorable prognosis, it is concerning that the mortality rate for this disease is increasing,” said Sophia C. Kamran, MD, the study’s lead author and a radiation oncologist at Massachusetts General Hospital.

Dr. Kamran urged new efforts to understand these trends and to make testicular cancer care more accessible for all patients.

Ms. Ghosh said that other researchers have identified the same disparity among Hispanic men with prostate cancer. “Even though testicular cancer is a rare, our finding warrants further investigation to find the basis of these disparities to better serve the Hispanic community.”

Other studies have shown higher likelihood of later stage diagnosis and worse survival outcomes among Black patients.

No funding sources were reported for this study.
