Abnormal mitochondrial activity in pain-processing areas of the brain may explain why some persons with type 2 diabetes experience painful peripheral neuropathy while others do not, new U.K. study findings have suggested.

A greater ratio of adenosine triphosphate (ATP) – “the cellular energy currency of all life” – to phosphocreatine (PCr) was observed in the somatosensory cortex and right thalamus in those with painful diabetic peripheral neuropathy (DPN). Importantly, this correlated with neuropathic pain symptom intensity as measured by the Neuropathic Pain Symptom Inventory (NPSI) and the Doleur Neuroathique en 4 (DN4).

The findings suggest that altered cerebral phosphorus metabolite ratios may serve as a biomarker of DPN, said the study’s investigators.

“Normally the ATP:Cr ratio will be unaltered, but there’s stress to the brain that might change,” Gordon Sloan, a clinical research fellow within the Diabetes Research Unit at the Royal Hallamshire Hospital in Sheffield (England) said at the virtual annual meeting of the European Association for the Study of Diabetes.

DPN affects around a quarter of patients with type 2 diabetes but treatments are “inadequate”, and “unfortunately fewer than a third of individuals receive 50% or greater pain relief from current neuropathic pain treatments,” Mr. Sloan said. “Ultimately, this lack of understanding of the pathophysiology of the condition is therefore clear rationale to investigate the disease mechanisms further and to find novel targets for treatments,” he added.


 

Brain metabolites offer clues to neuropathic pain levels

The thalamus and primary somatosensory cortex are two key areas of the brain that are involved in the perception of painful stimuli, Mr. Sloan explained. “The thalamus receives most of the slowest sensory impulses from the peripheral nervous system modulating and processing them for relaying the signals to the rest of the pain matrix, including the somatosensory cortex where these sensations are interpreted and localized.”

Prior imaging work by Mr. Sloan’s group and others have shown that there are alterations in the functioning of both these brain areas in those with painful DPN versus healthy volunteers and those with type 2 diabetes but no DPN. So for their current study, Mr. Sloan and associates from Sheffield University and Sheffield Teaching Hospitals National Health Service Trust, used an advanced imaging method – phosphorus magnetic resonance spectroscopy (MRS) – to scan the thalamus and somatosensory cortex of 43 persons with type 2 diabetes and 12 healthy volunteers. Of those with diabetes, 11 had no DPN, 12 had DPN but were not currently in pain, and 20 had painful DPN.

From the scans, three phosphorus metabolite ratios were calculated, which gave an indication of mitochondrial activity: first, the ATP to PCr ratio, which gives a measure of cellular energy status; second, the ATP to inorganic phosphate (Pi) ratio, which measures oxidative phosphorylation; and third, the ratio of phosphomonoesters (PME) to phosphodiesters (PDE), which gives a measure of cell membrane turnover.

“We have measured the ratio of high-energy phosphate levels which are an indirect representation of the balance between energy generation, reserve and usage in the brain,” Mr. Sloan said.

The subjects studied were of a similar age, around 63 years on average, and well matched in terms of their sex and body mass index. Those with diabetes of course had higher blood glucose and glycated hemoglobin than did the healthy volunteers during the scans. Among those with diabetes, those with DPN were significantly more likely to have a longer duration of diabetes (12.5 years for painful DPN and 15.8 years for nonpainful DPN) than were those with no DPN (8.7 years).

Furthermore, those with DPN had higher scores on the Neuropathic Pain Symptom Inventory (NPSI) than did those without, although there was not much difference between those with painful or nonpainful DPN. On the other had, those with painful DPN were more likely to have higher scores when using the Doleur Neuroathique en 4 (DN4) to assess their pain level.

Results showed significant changes in cerebral cellular bioenergetics in the pain processing regions of the brain in those with painful DPN. The ATP:PCr at the thalamus and at the somatosensory cortex was significantly higher in those with painful DPN, compared with healthy volunteers. The other measures of phosphorus metabolite levels (ATP:Pi and PME:PDE) were unaltered.

“We hypothesize that the findings of the study are suggestive of increased energy demands in regions of pain perception due to increased neuronal activity” said Dr. Sloan.

The study’s results add further evidence for cerebral alterations playing a key role in the generation and maintenance of pain in painful DPN.

A pathologic complete response (pCR) to targeted therapy in HER2-positive breast cancer portends good long-term outcomes, according to final results of the phase 3 NeoALTTO/BIG 1-06 trial. In fact, for the majority of women, pCR appears to be a marker of cure.

The trial was conducted among 455 women with HER2-positive breast cancer tumors measuring at least 2 cm who were randomized to neoadjuvant trastuzumab, lapatinib, or both drugs in combination, each together with paclitaxel, followed by more chemotherapy and more of the same targeted therapy after surgery.

Relative to trastuzumab alone, trastuzumab plus lapatinib improved rates of pCR, as shown by data published in The Lancet in 2012. However, the dual therapy did not significantly prolong event-free or overall survival, according to data published in The Lancet Oncology in 2014. Findings were similar in an update at a median follow-up of 6.7 years, published in the European Journal of Cancer in 2019.

Study investigator Paolo Nuciforo, MD, PhD, of the Vall d’Hebron Institute of Oncology in Barcelona, reported the trial’s final results, now at a median follow-up of 9.7 years, at the 12th European Breast Cancer Conference.

There were no significant differences in 9-year outcomes by specific HER2-targeted therapy. However, in a landmark analysis among women who were event free and still on follow-up 30 weeks after randomization, those achieving pCR with any of the therapies were 52% less likely to experience events and 63% less likely to die. Benefit was greatest in the subset of patients with hormone receptor–negative disease.

“The long-term follow-up confirms that, independent of the treatment regimen that we use – in this case, the dual blockade was with lapatinib, but similar results can be expected with other dual blockade – the pCR is a very robust surrogate biomarker of long-term survival,” Dr. Nuciforo commented in a press conference, noting that dual trastuzumab and pertuzumab has emerged as the standard of care.

“If we really pay attention to the curve, it’s maybe interesting to see that, after year 6, we actually don’t see any events in the pCR population. So this means that these patients are almost cured. We cannot say the word ‘cure’ in cancer, but it’s very reassuring to see the long-term survival analysis support the use of pCR as an endpoint,” he elaborated.

“Our results support the design of future trial concepts in HER2-positive early breast cancer which use pCR as an early efficacy readout of long-term benefit to escalate or deescalate therapy, particularly for hormone receptor–negative tumors,” Dr. Nuciforo concluded.
 

Support for current practice

“The study lends support for the current practice of risk-stratifying by pCR as well as making treatment decisions regarding T-DM1 [trastuzumab emtansine], and there hasn’t been a big change between 5-year and 9-year outcomes,” Lisa A. Carey, MD, of the University of North Carolina at Chapel Hill Lineberger Comprehensive Cancer Center, commented in an interview.

The lack of late events in the group with pCR technically meets the definition of cure, Dr. Carey said. “I think it speaks to the relatively early relapse risk in HER2-positive breast cancer and the impact of anti-HER2 therapy that carries forward. In general, these are findings similar to long-term findings of other trials and I suspect will be the same for any regimen.”

Although the analysis of dual lapatinib-trastuzumab therapy was underpowered, the trends seen align with favorable results in the adjuvant APHINITY trial (which combined trastuzumab with pertuzumab) and the neoadjuvant CALGB 40601 trial (which combined trastuzumab with lapatinib), according to Dr. Carey. “There has been a trend in every other study [of dual therapy] performed, so this is consistent.”
 

Study details

NeoALTTO is noteworthy for having the longest follow-up among all neoadjuvant studies of dual HER2 blockade in early breast cancer, Dr. Nuciforo said.

He reported no significant difference in survival between the treatment arms at 9 years.

The 9-year rate of event-free survival was 69% with lapatinib-trastuzumab, 63% with lapatinib alone, and 65% with trastuzumab alone. The corresponding 9-year rates of overall survival were 80%, 77%, and 76%, respectively.

However, there were significant differences in event-free and overall survival among women who achieved pCR and those who did not.

“pCR was achieved for almost twice as many patients treated with dual HER2 blockade, compared with patients in the single-agent arms,” Dr. Nuciforo pointed out. The pCR rate was 51.3% with lapatinib-trastuzumab, 24.7% with lapatinib alone, and 29.5% with trastuzumab alone.

Relative to peers who did not achieve pCR, women who did had better 9-year event-free survival (77% vs. 61%; adjusted hazard ratio, 0.48; P = .0008). The benefit was stronger in hormone receptor–negative disease (HR, 0.43; P = .002) than in hormone receptor–positive disease (HR, 0.60; P = .15).

The pattern was similar for overall survival at 9 years – 88% in those who achieved a pCR and 72% in those who did not (adjusted HR, 0.37; P = .0004). Again, greater benefit was seen in hormone receptor–negative disease (HR, 0.33; P = .002) than in hormone receptor–positive disease (HR, 0.44; P = .09).

“Biomarker-driven approaches may improve selection of those patients who are more likely to respond to anti-HER2 therapies,” Dr. Nuciforo proposed.

From 6 years onward, there were no additional fatal adverse events or nonfatal serious adverse events recorded, and no additional primary cardiac endpoints were recorded.

The study was funded by Novartis. Dr. Nuciforo and Dr. Carey disclosed no conflicts of interest.

The combined features of benign breast disease may help better personalize breast cancer screening strategies, according to a retrospective cohort study reported at the 12th European Breast Cancer Conference.

“Benign breast disease is a key risk factor for breast cancer risk prediction,” commented presenting investigator Marta Román, PhD, of the Hospital del Mar Medical Research Institute in Barcelona. “Those women who have had a benign breast disease diagnosis have an increased risk that lasts for at least 20 years.”

To assess the combined influence of various attributes of benign breast disease, the investigators studied 629,087 women, aged 50-69 years, in Spain who underwent population-based mammographic breast cancer screening during 1994-2015 and did not have breast cancer at their prevalent (first) screen. The mean follow-up was 7.8 years.

Results showed that breast cancer risk was about three times higher for women with benign breast disease that was proliferative or that was detected on an incident screen, relative to peers with no benign breast disease. When combinations of factors were considered, breast cancer risk was most elevated – more than four times higher – for women with proliferative benign breast disease with atypia detected on an incident screen.

“We believe that these findings should be considered when discussing risk-based personalized screening strategies because these differences between prevalent and incident screens might be important if we want to personalize the screening, whether it’s the first time a woman comes to the screening program or a subsequent screen,” Dr. Román said.
 

Practice changing?

The study’s large size and population-based design, likely permitting capture of most biopsy results, are strengths, Mark David Pearlman, MD, of the University of Michigan, Ann Arbor, commented in an interview.

But its observational, retrospective nature opens the study up to biases, such as uncertainty as to how many women were symptomatic at the time of their mammogram and the likelihood of heightened monitoring after a biopsy showing hyperplasia, Dr. Pearlman cautioned.

“Moreover, the relative risk in this study for proliferative benign breast disease without atypia is substantially higher than prior observations of this group. This discrepancy was not discussed by the authors,” Dr. Pearlman said.

At present, women’s risk of breast cancer is predicted using well-validated models that include the question of prior breast biopsies, such as the Gail Model, the Tyrer-Cuzick model (IBIS tool), and the Breast and Ovarian Analysis of Disease Incidence and Carrier Estimation Algorithm, Dr. Pearlman noted.

“This study, without further validation within a model, would not change risk assessment,” he said, disagreeing with the investigators’ conclusions. “What I would say is that further study to determine how to use this observation to decide if any change in screening or management should occur would be more appropriate.”
 

Study details

The 629,087 women studied underwent 2,327,384 screens, Dr. Román reported. In total, screening detected 9,184 cases of benign breast disease and 9,431 breast cancers.

Breast cancer was diagnosed in 2.4% and 3.0% of women with benign breast disease detected on prevalent and incident screens, respectively, compared with 1.5% of women without any benign breast disease detected.

Elevation of breast cancer risk varied across benign breast disease subtype. Relative to peers without any benign disease, risk was significantly elevated for women with nonproliferative disease (adjusted hazard ratio, 1.95), proliferative disease without atypia (aHR, 3.19), and proliferative disease with atypia (aHR, 3.82).

Similarly, elevation of risk varied depending on the screening at which the benign disease was detected. Risk was significantly elevated when the disease was found at prevalent screens (aHR, 1.87) and more so when it was found at incident screens (aHR, 2.67).

There was no significant interaction of these two factors (P = .83). However, when combinations were considered, risk was highest for women with proliferative benign breast disease with atypia detected on incident screens (aHR, 4.35) or prevalent screens (aHR, 3.35), and women with proliferative benign breast disease without atypia detected on incident screens (aHR, 3.83).

This study was supported by grants from Instituto de Salud Carlos III FEDER and by the Research Network on Health Services in Chronic Diseases. Dr. Román and Dr. Pearlman disclosed no conflicts of interest.

The combined features of benign breast disease may help better personalize breast cancer screening strategies, according to a retrospective cohort study reported at the 12th European Breast Cancer Conference.

“Benign breast disease is a key risk factor for breast cancer risk prediction,” commented presenting investigator Marta Román, PhD, of the Hospital del Mar Medical Research Institute in Barcelona. “Those women who have had a benign breast disease diagnosis have an increased risk that lasts for at least 20 years.”

To assess the combined influence of various attributes of benign breast disease, the investigators studied 629,087 women, aged 50-69 years, in Spain who underwent population-based mammographic breast cancer screening during 1994-2015 and did not have breast cancer at their prevalent (first) screen. The mean follow-up was 7.8 years.

Results showed that breast cancer risk was about three times higher for women with benign breast disease that was proliferative or that was detected on an incident screen, relative to peers with no benign breast disease. When combinations of factors were considered, breast cancer risk was most elevated – more than four times higher – for women with proliferative benign breast disease with atypia detected on an incident screen.

“We believe that these findings should be considered when discussing risk-based personalized screening strategies because these differences between prevalent and incident screens might be important if we want to personalize the screening, whether it’s the first time a woman comes to the screening program or a subsequent screen,” Dr. Román said.
 

Practice changing?

The study’s large size and population-based design, likely permitting capture of most biopsy results, are strengths, Mark David Pearlman, MD, of the University of Michigan, Ann Arbor, commented in an interview.

But its observational, retrospective nature opens the study up to biases, such as uncertainty as to how many women were symptomatic at the time of their mammogram and the likelihood of heightened monitoring after a biopsy showing hyperplasia, Dr. Pearlman cautioned.

A COVID-19 vaccine could be proven effective within the last months of 2020, with distribution of first doses possible before the end of the year, according to Anthony S. Fauci, MD, director, National Institute of Allergy and Infectious Diseases, Bethesda, Md.

“Given the rate of infection that’s going on in this country, and the distribution of the clinical trial sites involving tens of thousands of volunteers, we project that we will have an answer as to whether or not we have a safe and effective vaccine by November or December,” Dr. Fauci said today in his virtual keynote address during the annual meeting of the American College of Chest Physicians.

“It may come earlier -- this month, in October,” he added in his remarks. “That is unlikely – it is more likely that we’ll have an answer in November and December.”

If that timing does come to pass, Dr. Fauci said, it’s possible that distribution of doses could start at the end of the year, continuing throughout the beginning and middle of 2021.

Although there are no guarantees, Dr. Fauci said he is “cautiously optimistic” regarding the timeline.

He said that his optimism is based in part on animal studies and phase 1 data that demonstrate robust neutralizing antibody responses to a vaccine that are equivalent to, if not greater than, natural infection with the SARS-CoV-2 virus that causes COVID-19.

Rapid development gives reason for hope

Ryan C. Maves, MD, FCCP, a critical care and infectious disease specialist at Naval Medical Center San Diego, said there is reason to be hopeful that a vaccine will be available by the end of the calendar year. He cautioned, however, that this timing is based on the assumption that one of the vaccines will be proven safe and effective very soon.

“We’re lucky to have multiple phase 3 trials using multiple vaccine technologies in different platforms,” Dr. Maves said in a panel discussion following Dr. Fauci’s remarks. “I think the odds are very high that one of them will be effective.”

“I’m hoping that multiple vaccines will be effective,” Dr. Maves added. “Then we’ll be in a good position of determining which is the best of several good options, as a society and as a world.”

COVID-19 vaccine development over the past year has been remarkably fast, especially given the previous record set by the mumps vaccine, which took about four years to go from initial steps to rollout, Dr. Maves noted.

Dr. Fauci said the federal government has taken a “strategic approach” to the COVID-19 vaccine that includes direct involvement in the research and development of six different vaccine candidates, five of which are now in phase 3 trials.

As part of that strategic approach, the study protocols are harmonized to have a common data and safety monitoring board, common primary and secondary endpoints, and an independent statistical group to determine correlates of protection, Dr. Fauci said.

Prioritizing COVID-19 vaccine distribution

Who gets COVID-19 vaccine first will be a challenge for governmental organizations as well as bioethicists, who have proposed different strategies for fairly prioritizing different groups for access.

Reaching communities of color will be an important consideration for prioritization, according to Dr. Maves, given the disproportionate burden of disease on Black and Hispanic individuals, among other such populations.

COVID-19–related hospitalization rates have been substantially higher in communities of color, Dr. Fauci said in his keynote address. Age-adjusted hospitalization rates for Hispanic/Latinx and Black populations are 375 to 368 per 100,000, respectively, compared with just 82 per 100,000 for White non-Hispanics, according to data from the Centers for Disease Control and Prevention.

Outreach to those communities should include building trust in those populations that they will benefit from a safe and effective vaccine, and making sure that the vaccine is available to those communities as quickly as possible, Dr. Maves said.

Patients with COVID-19 who present with ST-segment elevation MI (STEMI) represent a unique, high-risk population with greater risks for in-hospital death and stroke, according to initial results from the North American COVID-19 ST-Segment Elevation Myocardial Infarction Registry (NACMI).

Although COVID-19–confirmed patients were less likely to undergo angiography than patients under investigation (PUI) for COVID-19 or historical STEMI activation controls, 71% underwent primary percutaneous coronary intervention (PCI).

“Primary PCI is preferable and feasible in COVID-19–positive patients, with door-to-balloon times similar to PUI or COVID-negative patients, and that supports the updated COVID-specific STEMI guidelines,” study cochair Timothy D. Henry, MD, said in a late-breaking clinical science session at TCT 2020, the Transcatheter Cardiovascular Therapeutics virtual annual meeting.

The multisociety COVID-specific guidelines were initially issued in April, endorsing PCI as the standard of care and allowing for consideration of fibrinolysis-based therapy at non-PCI capable hospitals.

Five previous publications on a total of 174 COVID-19 patients with ST-elevation have shown there are more frequent in-hospital STEMI presentations, more cases without a clear culprit lesion, more thrombotic lesions and microthrombi, and higher mortality, ranging from 12% to 72%. Still, there has been considerable controversy over exactly what to do when COVID-19 patients with ST elevation reach the cath lab, he said at the meeting sponsored by the Cardiovascular Research Foundation.

NACMI represents the largest experience with ST-elevation patients and is a unique collaboration between the Society for Cardiovascular Angiography and Interventions, Canadian Association of Interventional Cardiology, American College of Cardiology, and Midwest STEMI Consortium, noted Dr. Henry, who is medical director of the Lindner Center for Research and Education at the Christ Hospital, Cincinnati.

The registry enrolled any COVID-19–positive patient or person under investigation older than 18 years with ST-segment elevation or new-onset left bundle branch block on electrocardiogram with a clinical correlate of myocardial ischemia such as chest pain, dyspnea, cardiac arrest, shock, or mechanical ventilation. There were no exclusion criteria.

Data from 171 patients with confirmed COVID-19 and 423 PUI from 64 sites were then propensity-matched to a control population from the Midwest STEMI Consortium, a prospective, multicenter registry of consecutive STEMI patients.

The three groups were similar in sex and age but there was a striking difference in race, with 27% of African American and 24% of Hispanic patients COVID-confirmed, compared with 11% and 6% in the PUI group and 4% and 1% in the control group. Likewise, there was a significant increase in diabetes (44% vs. 33% vs. 20%), which has been reported previously with influenza.

COVID-19–positive patients, as compared with PUI and controls, were significantly more likely to present with cardiogenic shock before PCI (20% vs. 14% vs. 5%), but not cardiac arrest (12% vs. 17% vs. 11%), and to have lower left ventricular ejection fractions (45% vs. 45% vs. 50%).

They also presented with more atypical symptoms than PUI patients, particularly infiltrates on chest x-ray (49% vs. 17%) and dyspnea (58% vs. 38%). Data were not available for these outcomes among historic controls.

Importantly, 21% of the COVID-19 patients did not undergo angiography, compared with 5% of PUI patients and 0% of controls (P < .001), “which is much higher than we would expect or have suspected,” Dr. Henry said. Thrombolytic use was very uncommon in those undergoing angiography, likely as a result of the guidelines.

Very surprisingly, there were no differences in door-to-balloon times between the COVID-positive, PUI, and control groups despite the ongoing pandemic (80 min vs. 78 min vs. 86 min).

But there was clear worsening in in-hospital mortality in COVID-19–positive patients (32% vs. 12% and 6%; P < .001), as well as in-hospital stroke (3.4% vs. 2% vs. 0.6%) that reached statistical significance only when compared with historical controls (P = .039). Total length of stay was twice as long in COVID-confirmed patients as in both PUI and controls (6 days vs. 3 days; P < .001).

Following the formal presentation, invited discussant Philippe Gabriel Steg, MD, Imperial College London, said the researchers have provided a great service in reporting the data so quickly but noted that an ongoing French registry of events before, during, and after the first COVID-19 wave has not seen an increased death rate.

“Can you tease out whether the increased death rate is related to cardiovascular deaths or to COVID-related pneumonias, shocks, ARDSs [acute respiratory distress syndromes], and so on and so forth? Because our impression – and that’s what we’ve published in Lancet Public Health – is that the cardiovascular morality rate doesn’t seem that affected by COVID.”

Dr. Henry replied that these are early data but “I will tell you that patients who did get PCI had a mortality rate that was only around 12% or 13%, and the patients who did not undergo angiography or were treated with medical therapy had higher mortality. Now, of course, that’s selected and we need to do a much better matching and look at that, but that’s our goal and we will have that information,” he said.

During a press briefing on the study, discussant Renu Virmani, MD, president and founder of CVPath Institute, noted that, in their analysis of 40 autopsy cases from Bergamot, Italy, small intramyocardial microthrombi were seen in nine patients, whereas epicardial microthrombi were seen in only three or four.

“Some of the cases are being taken as being related to coronary disease but may be more thrombotic than anything else,” she said. “I think there’s a combination, and that’s why the outcomes are so poor. You didn’t show us TIMI flow but that’s something to think about: Was TIMI flow different in the patients who died because you have very high mortality? I think we need to get to the bottom of what is the underlying cause of that thrombosis.”

During a press briefing on the study, discussant Renu Virmani, MD, president and founder of CVPath Institute, noted that, in their analysis of 40 autopsy cases from Bergamot, Italy, small intramyocardial microthrombi were seen in nine patients, whereas epicardial microthrombi were seen in only three or four.

“Some of the cases are being taken as being related to coronary disease but may be more thrombotic than anything else,” she said. “I think there’s a combination, and that’s why the outcomes are so poor. You didn’t show us TIMI flow but that’s something to think about: Was TIMI flow different in the patients who died because you have very high mortality? I think we need to get to the bottom of what is the underlying cause of that thrombosis.”

Patients with COVID-19 who present with ST-segment elevation MI (STEMI) represent a unique, high-risk population with greater risks for in-hospital death and stroke, according to initial results from the North American COVID-19 ST-Segment Elevation Myocardial Infarction Registry (NACMI).

Although COVID-19–confirmed patients were less likely to undergo angiography than patients under investigation (PUI) for COVID-19 or historical STEMI activation controls, 71% underwent primary percutaneous coronary intervention (PCI).

“Primary PCI is preferable and feasible in COVID-19–positive patients, with door-to-balloon times similar to PUI or COVID-negative patients, and that supports the updated COVID-specific STEMI guidelines,” study cochair Timothy D. Henry, MD, said in a late-breaking clinical science session at TCT 2020, the Transcatheter Cardiovascular Therapeutics virtual annual meeting.

The multisociety COVID-specific guidelines were initially issued in April, endorsing PCI as the standard of care and allowing for consideration of fibrinolysis-based therapy at non-PCI capable hospitals.

Five previous publications on a total of 174 COVID-19 patients with ST-elevation have shown there are more frequent in-hospital STEMI presentations, more cases without a clear culprit lesion, more thrombotic lesions and microthrombi, and higher mortality, ranging from 12% to 72%. Still, there has been considerable controversy over exactly what to do when COVID-19 patients with ST elevation reach the cath lab, he said at the meeting sponsored by the Cardiovascular Research Foundation.

NACMI represents the largest experience with ST-elevation patients and is a unique collaboration between the Society for Cardiovascular Angiography and Interventions, Canadian Association of Interventional Cardiology, American College of Cardiology, and Midwest STEMI Consortium, noted Dr. Henry, who is medical director of the Lindner Center for Research and Education at the Christ Hospital, Cincinnati.

The registry enrolled any COVID-19–positive patient or person under investigation older than 18 years with ST-segment elevation or new-onset left bundle branch block on electrocardiogram with a clinical correlate of myocardial ischemia such as chest pain, dyspnea, cardiac arrest, shock, or mechanical ventilation. There were no exclusion criteria.

Data from 171 patients with confirmed COVID-19 and 423 PUI from 64 sites were then propensity-matched to a control population from the Midwest STEMI Consortium, a prospective, multicenter registry of consecutive STEMI patients.

The three groups were similar in sex and age but there was a striking difference in race, with 27% of African American and 24% of Hispanic patients COVID-confirmed, compared with 11% and 6% in the PUI group and 4% and 1% in the control group. Likewise, there was a significant increase in diabetes (44% vs. 33% vs. 20%), which has been reported previously with influenza.

COVID-19–positive patients, as compared with PUI and controls, were significantly more likely to present with cardiogenic shock before PCI (20% vs. 14% vs. 5%), but not cardiac arrest (12% vs. 17% vs. 11%), and to have lower left ventricular ejection fractions (45% vs. 45% vs. 50%).

They also presented with more atypical symptoms than PUI patients, particularly infiltrates on chest x-ray (49% vs. 17%) and dyspnea (58% vs. 38%). Data were not available for these outcomes among historic controls.

Importantly, 21% of the COVID-19 patients did not undergo angiography, compared with 5% of PUI patients and 0% of controls (P < .001), “which is much higher than we would expect or have suspected,” Dr. Henry said. Thrombolytic use was very uncommon in those undergoing angiography, likely as a result of the guidelines.

Very surprisingly, there were no differences in door-to-balloon times between the COVID-positive, PUI, and control groups despite the ongoing pandemic (80 min vs. 78 min vs. 86 min).

But there was clear worsening in in-hospital mortality in COVID-19–positive patients (32% vs. 12% and 6%; P < .001), as well as in-hospital stroke (3.4% vs. 2% vs. 0.6%) that reached statistical significance only when compared with historical controls (P = .039). Total length of stay was twice as long in COVID-confirmed patients as in both PUI and controls (6 days vs. 3 days; P < .001).

Following the formal presentation, invited discussant Philippe Gabriel Steg, MD, Imperial College London, said the researchers have provided a great service in reporting the data so quickly but noted that an ongoing French registry of events before, during, and after the first COVID-19 wave has not seen an increased death rate.

“Can you tease out whether the increased death rate is related to cardiovascular deaths or to COVID-related pneumonias, shocks, ARDSs [acute respiratory distress syndromes], and so on and so forth? Because our impression – and that’s what we’ve published in Lancet Public Health – is that the cardiovascular morality rate doesn’t seem that affected by COVID.”

Dr. Henry replied that these are early data but “I will tell you that patients who did get PCI had a mortality rate that was only around 12% or 13%, and the patients who did not undergo angiography or were treated with medical therapy had higher mortality. Now, of course, that’s selected and we need to do a much better matching and look at that, but that’s our goal and we will have that information,” he said.

Long-acting cabotegravir and rilpivirine (CAB/RPV) administered intramuscularly monthly or every 2 months yielded high rates of efficacy and a favorable safety profile in women with HIV, according to results from the ATLAS-2M study, presented at the HIV Glasgow 2020 Virtual Conference, held October 5-8. The women also reported high satisfaction with the regimen, compared with daily oral antiretroviral therapy.

Previously reported results had shown that the two-drug combination administered every 8 weeks (600 mg cabotegravir and 900 mg rilpivirine) was noninferior to injections every 4 weeks (400 mg cabotegravir and 600 mg rilpivirine) in adults with HIV during the open-label phase 3b ATLAS-2M trial. Further, the ATLAS and FLAIR phase 3 trials had shown the 4-week administration of the therapy to be noninferior to a daily oral three-drug antiretroviral therapy.

Paul Benn, MBBS, of ViiV Healthcare (which is seeking regulatory approval for CAB/RPV treatment), and his colleagues completed a planned subgroup analysis of women in the ATLAS-2M trial. The primary endpoint was the proportion of intention-to-treat participants with plasma HIV-1 RNA of at least 50 copies/mL with a noninferiority margin of 4% at 48 weeks. The secondary endpoint was the proportion of participants with HIV-1 RNA under 50 copies/mL with a noninferiority margin of 10%.

Among the 280 women enrolled, 137 were randomly assigned to receive injections every 8 weeks, and 143 to receive injections every 4 weeks. A majority of the women (56%) were White, the median age was 44 years, and just over half (53%) were treatment naive with cabotegravir and rilpivirine.

At 48 weeks, 3.6% of women in the 8-week group and 0% of women in the 4-week group had at least 50 copies/mL of HIV-1 RNA. In both arms, 91% of participants had HIV-1 RNA under 50 copies/mL. Plasma concentrations of cabotegravir and rilpivirine were similar between the women and the overall study population.

Confirmed virologic failure occurred in five women, all before week 24. Three of the women were subtype A/A1, and four of them had archived nonnucleoside reverse transcriptase inhibitor (NNRTI) resistance–associated mutations.

There were no significant differences in the safety profile between the groups; 99% of injection site reactions that occurred were mild to moderate and lasted a median 3-4 days. Fewer than 4% of participants discontinued because of adverse events – five women in the 8-week group and five women in the 4-week group. Four women cited injection site reactions as the reason for discontinuation.

Women not previously treated with CAB/RPV reported increased treatment satisfaction on the HIV Treatment Satisfaction Questionnaire, a score of 5.4 in the 8-week group and 3.9 in the 4-week group. Among those with prior CAB/RPV treatment, 88% preferred the 8-weekly injections, 8% preferred the 4-weekly injections, and 2% preferred oral dosing.

Long-acting CAB/RPV is an investigational formulation. In December 2019, the Food and Drug Administration denied approval to the formulation on the basis of manufacturing and chemistry concerns, according to a company press release.

Measuring glycated albumin (glycoalbumin, GA) in tears could be a future way for those with diabetes to monitor their blood sugar levels noninvasively.

In a 100-patient trial, levels of GA in tears were found to be strongly correlated (r = .722; P < .001) with those in the blood.

“GA levels in blood are widely measured in clinical practice in Japan,” said study investigator Masakazu Aihara, MD, PhD, in an interview.

“It’s a biomarker that reflects the 2-week average blood glucose level like fructosamine,” explained the researcher from the department of diabetes and metabolic diseases in the Graduate School of Medicine at the University of Tokyo.

This could make it a better biomarker for detecting earlier changes in blood glucose than glycated hemoglobin (HbA_1c), which reflects changes in blood glucose over the preceding 2-3 months.

Prior studies had shown that glucose levels can be measured in tear samples and that tear glucose levels correlated with blood glucose levels, Dr. Aihara and fellow researchers observed in a poster presentation at the virtual annual meeting of the European Association for the Study of Diabetes.

“While looking for noninvasive diabetes-related markers, we found that tears contained albumin. Based on this fact, we thought that GA could be measured in tears,” Dr. Aihara explained.

Using tears to test for biomarkers is not a new idea – tears not only protect the eye, they contain a variety of large proteins, and their composition can change with disease. Indeed, researchers have been looking at their usefulness in helping find biomarkers for Parkinson’s disease and diabetic peripheral neuropathy.

During their study, Dr. Aihara and associates collected tear and blood samples at the same time. Tear samples were assessed using liquid chromatography (LC) and mass spectrometry (MS). An enzymic method was used to measure GA levels in blood. Several diagnosis assay kits for GA are sold in Japan, Dr. Aihara said, and at least one of these has U.S. Food and Drug Administration approval.

Multiple regression analysis revealed that the correlation between GA levels in tears and in blood was maintained even after adjustment for age, gender, nephropathy stage, and obesity (P < .001). The results obtained from the tests were thought unlikely to be affected by any changes in the concentration or dilution of tear samples.

“Since GA levels in blood are clinically used in all types of diabetes, GA levels in tears is also expected to be useful in all types of diabetes,” Dr. Aihara said, noting that the effects of receiving treatment on GA levels in tears is something that he would like to look at.

The team would also like to optimize how tear samples are collected and reduce the volume of tears that are required for analysis. At the moment tears are collected via a dropper and about 100 mcL of tear fluid is required for measurement.

“At present, it is difficult to measure for dry eye patients because sufficient tears cannot be collected, but if the required amount of tears decreases in the future, it may be indicated for dry eye patients,” Dr. Aihara noted.

Discussing further research plans, he added: “We would like to examine the conditions of LC-MS/MS so that the correlation coefficient with GA in blood can be improved.

“Since LC-MS/MS is a large equipment in the laboratory, I would like to develop a device that can measure at the clinic or at home in the future.”

The study was funded by a grant from the Japan Agency for Medical Research and Development. Dr. Aihara had no conflicts of interest.

A 24-hour continuous subcutaneous infusion of foslevodopa/foscarbidopa improved Parkinson’s disease (PD) motor symptoms during all waking hours for patients with advanced disease, according to a new study. The beneficial effects of these phosphate prodrugs of levodopa and carbidopa were most noticeable in the early morning, results of the phase 1B study showed.

As Parkinson’s disease progresses and dosing of oral levodopa/carbidopa (LD/CD) increases, its therapeutic window narrows, resulting in troublesome dyskinesia at peak drug levels and tremors and rigidity when levels fall.

“Foslevodopa/foscarbidopa shows lower ‘off’ time than oral levodopa/carbidopa, and this was statistically significant. Also, foslevodopa/foscarbidopa (fosL/fosC) showed more ‘on’ time without dyskinesia, compared with oral levodopa/carbidopa. This was also statistically significant,” lead author Sven Stodtmann, PhD, of AbbVie GmbH, Ludwigshafen, Germany, reported in his recorded presentation at the Movement Disorders Society’s 23rd International Congress of Parkinson’s Disease and Movement Disorder (Virtual) 2020.
 

Continuous infusion versus oral therapy

The analysis included 20 patients, and all data from these individuals were collected between 4:30 a.m. and 9:30 p.m.

Participants were 12 men and 8 women, aged 30-80 years, with advanced, idiopathic Parkinson’s disease responsive to levodopa but inadequately controlled on their current stable therapy, having a minimum of 2.5 off hours/day. Mean age was 61.3 plus or minus 10.5 years (range 35-77 years).

In this single-arm, open-label study, they received subcutaneous infusions of personalized therapeutic doses of fosL/fosC 24 hours/day for 28 days after a 10- to 30-day screening period during which they recorded LD/CD doses in a diary and had motor symptoms monitored using a wearable device.

Following the screening period, fosL/fosC doses were titrated over up to 5 days, with subsequent weekly study visits, for a total time on fosL/fosC of 28 days. Drug titration was aimed at maximizing functional on time and minimizing the number of off episodes while minimizing troublesome dyskinesia.

Continuous infusion of fosL/fosC performed better than oral LD/CD on all counts.

“The off time is much lower in the morning for people on foslevodopa/foscarbidopa [compared with oral LD/CD] because this is a 24-hour infusion product,” Dr. Stodtmann explained.

The effect was maintained over the course of the day with little fluctuation with fosL/fosC, off periods never exceeding about 25% between 4:30 a.m. and 9 p.m. For LD/CD, off periods were highest in the early morning and peaked at about 50% on a 3- to 4-hour cycle during the course of the day.

Increased on time without dyskinesia varied between about 60% and 80% during the day with fosL/fosC, showing the greatest difference between fosL/fosC and oral LD/CD in the early morning hours.

“On time with nontroublesome dyskinesia was lower for foscarbidopa/foslevodopa, compared to oral levodopa/carbidopa, but this was not statistically significant,” Dr. Stodtmann said. On time with troublesome dyskinesia followed the same pattern, again, not statistically significant.

Looking at the data another way, the investigators calculated the odds ratios of motor symptoms using fosL/fosC, compared with oral LD/CD. Use of fosL/fosC was associated with a 59% lower risk of being in the off state during the day, compared with oral LD/CD (odds ratio, 0.4; 95% confidence interval, 0.2-0.7; P < .01). Similarly, the probability of being in the on state without dyskinesia was much greater with fosL/fosC (OR, 2.75; 95% CI, 1.08-6.99; P < .05).
 

Encouraging, but more data needed

Indu Subramanian, MD, of the department of neurology at the University of California, Los Angeles, and director of the Parkinson’s Disease Research, Education, and Clinical Center at the West Los Angeles Veterans Affairs Hospital, commented that the field has been waiting to see data on fosL/fosC.

“It seems like it’s pretty reasonable in terms of what the goals were, which is to improve stability of Parkinson’s symptoms, to improve off time and give on time without troublesome dyskinesia,” she said. “So I think those [goals] have been met.”

Dr. Subramanian, who was not involved with the research, said she would have liked to have seen results concerning safety of this drug formulation, which the presentation lacked, “because historically, there have been issues with nodule formation and skin breakdown, things like that, due to the stability of the product in the subcutaneous form. … So, always to my understanding, there has been this search for things that are tolerated in the subcutaneous delivery.”

If this formulation proves safe and tolerable, Dr. Subramanian sees a potential place for it for some patients with advanced Parkinson’s disease.

“Certainly a subcutaneous formulation will be better than something that requires … deep brain surgery or even a pump insertion like Duopa [carbidopa/levodopa enteral suspension, AbbVie] or something like that,” she said. “I think [it] would be beneficial over something with the gut because the gut historically has been a problem to rely on in advanced Parkinson’s patients due to slower transit times, and the gut itself is affected with Parkinson’s disease.”

Dr. Stodtmann and all coauthors are employees of AbbVie, which was the sponsor of the study and was responsible for all aspects of it. Dr. Subramanian has given talks for Acadia Pharmaceuticals and Acorda Therapeutics in the past.

As Parkinson’s disease progresses and dosing of oral levodopa/carbidopa (LD/CD) increases, its therapeutic window narrows, resulting in troublesome dyskinesia at peak drug levels and tremors and rigidity when levels fall.

“Foslevodopa/foscarbidopa shows lower ‘off’ time than oral levodopa/carbidopa, and this was statistically significant. Also, foslevodopa/foscarbidopa (fosL/fosC) showed more ‘on’ time without dyskinesia, compared with oral levodopa/carbidopa. This was also statistically significant,” lead author Sven Stodtmann, PhD, of AbbVie GmbH, Ludwigshafen, Germany, reported in his recorded presentation at the Movement Disorders Society’s 23rd International Congress of Parkinson’s Disease and Movement Disorder (Virtual) 2020.
 

Continuous infusion versus oral therapy

The analysis included 20 patients, and all data from these individuals were collected between 4:30 a.m. and 9:30 p.m.

Participants were 12 men and 8 women, aged 30-80 years, with advanced, idiopathic Parkinson’s disease responsive to levodopa but inadequately controlled on their current stable therapy, having a minimum of 2.5 off hours/day. Mean age was 61.3 plus or minus 10.5 years (range 35-77 years).

In this single-arm, open-label study, they received subcutaneous infusions of personalized therapeutic doses of fosL/fosC 24 hours/day for 28 days after a 10- to 30-day screening period during which they recorded LD/CD doses in a diary and had motor symptoms monitored using a wearable device.

Following the screening period, fosL/fosC doses were titrated over up to 5 days, with subsequent weekly study visits, for a total time on fosL/fosC of 28 days. Drug titration was aimed at maximizing functional on time and minimizing the number of off episodes while minimizing troublesome dyskinesia.

Continuous infusion of fosL/fosC performed better than oral LD/CD on all counts.

“The off time is much lower in the morning for people on foslevodopa/foscarbidopa [compared with oral LD/CD] because this is a 24-hour infusion product,” Dr. Stodtmann explained.

The effect was maintained over the course of the day with little fluctuation with fosL/fosC, off periods never exceeding about 25% between 4:30 a.m. and 9 p.m. For LD/CD, off periods were highest in the early morning and peaked at about 50% on a 3- to 4-hour cycle during the course of the day.

Increased on time without dyskinesia varied between about 60% and 80% during the day with fosL/fosC, showing the greatest difference between fosL/fosC and oral LD/CD in the early morning hours.

“On time with nontroublesome dyskinesia was lower for foscarbidopa/foslevodopa, compared to oral levodopa/carbidopa, but this was not statistically significant,” Dr. Stodtmann said. On time with troublesome dyskinesia followed the same pattern, again, not statistically significant.

Looking at the data another way, the investigators calculated the odds ratios of motor symptoms using fosL/fosC, compared with oral LD/CD. Use of fosL/fosC was associated with a 59% lower risk of being in the off state during the day, compared with oral LD/CD (odds ratio, 0.4; 95% confidence interval, 0.2-0.7; P < .01). Similarly, the probability of being in the on state without dyskinesia was much greater with fosL/fosC (OR, 2.75; 95% CI, 1.08-6.99; P < .05).
 

Encouraging, but more data needed

Indu Subramanian, MD, of the department of neurology at the University of California, Los Angeles, and director of the Parkinson’s Disease Research, Education, and Clinical Center at the West Los Angeles Veterans Affairs Hospital, commented that the field has been waiting to see data on fosL/fosC.

“It seems like it’s pretty reasonable in terms of what the goals were, which is to improve stability of Parkinson’s symptoms, to improve off time and give on time without troublesome dyskinesia,” she said. “So I think those [goals] have been met.”

Dr. Subramanian, who was not involved with the research, said she would have liked to have seen results concerning safety of this drug formulation, which the presentation lacked, “because historically, there have been issues with nodule formation and skin breakdown, things like that, due to the stability of the product in the subcutaneous form. … So, always to my understanding, there has been this search for things that are tolerated in the subcutaneous delivery.”

If this formulation proves safe and tolerable, Dr. Subramanian sees a potential place for it for some patients with advanced Parkinson’s disease.

“Certainly a subcutaneous formulation will be better than something that requires … deep brain surgery or even a pump insertion like Duopa [carbidopa/levodopa enteral suspension, AbbVie] or something like that,” she said. “I think [it] would be beneficial over something with the gut because the gut historically has been a problem to rely on in advanced Parkinson’s patients due to slower transit times, and the gut itself is affected with Parkinson’s disease.”

Dr. Stodtmann and all coauthors are employees of AbbVie, which was the sponsor of the study and was responsible for all aspects of it. Dr. Subramanian has given talks for Acadia Pharmaceuticals and Acorda Therapeutics in the past.

Women with HIV and men with HIV who have sex with women (MSW) have substantially different experiences with treatment than men with HIV who have sex with men (MSM), according to findings presented at the HIV Glasgow 2020 Virtual Meeting. MSM had better overall health outcomes than the other two groups, the study found, suggesting that MSW and women have unmet needs that require providers’ attention.

Chinyere Okoli of ViiV Healthcare Global Medical Affairs in Brentford, England, and her associates administered a Web-based survey about HIV-related perceptions and behaviors to 2,389 adults with HIV in 25 countries. The respondents included 1,018 MSM, 479 MSW, and 696 women.

In high-income countries, MSM respondents had been diagnosed a median 9 years earlier, MSW respondents a median 4 years earlier, and women respondents a median 5 years earlier. In middle-income countries, diagnosis was a median 3 years ago for MSM respondents and a median 6 years for MSW and women respondents.

Rates of suboptimal adherence to antiretroviral therapy (ART) were lowest (15.5%) among MSM, compared with MSW (38.8%) and women (28%). Similarly, viral nonsuppression had occurred in only 10.9% of MSM, whereas it had occurred in 43.2% of MSW and 37.1% of women. A little more than one-third (36.5%) of MSM had suboptimal overall health, whereas 47.2% of MSW and 46.2% of women had suboptimal overall health (P < .05).

A similar percentage of MSM (38%) and women (38.2%) reported polypharmacy; both percentages were significantly lower than for MSW (45.1%; P = .020). Yet MSW were less likely than the other two groups to have comorbidities unrelated to HIV: 46.1%, compared with 64.6% of MSM and 56.7% of women (P < .001).

Although a higher proportion (63%) of MSW than MSM (44%) or women (55%) were receiving a multitablet ART regimen, MSW were least likely to consider the impact of side effects when they began ART and were most likely to experience side effects. Only 45% of MSW prioritized minimizing side effects when they began receiving ART, and more than half (52%) were experiencing side effects with their current regimen.

By contrast, a majority of MSM (60%) prioritized minimizing side effects at ART initiation, and only 35% currently had side effects. Women fell in the middle with 48% considering side effects when starting ART and 49% reporting current side effects.

The proportion of respondents who said ART side effects were affecting their lives was not significantly different: 69% of MSM, 73% of MSW, and 74% of women. However, 56% of MSW reported skipping at least one dose in the past month because of side effects, which was more than twice the percentage of MSM (24%; P < .001). One-third of women (33%) reported skipping at least one dose.

MSW were also least comfortable talking to their health care provider about ART side effects: 55% reported discomfort, compared with 34% of MSM and 43% of women. A high majority of MSW (87.9%) said they experienced barriers to talking to their providers about relevant health concerns. The proportion who reported barriers was lower for MSM (59%) and women (72.7%; P < .001).

The substantial differences between MSM and MSW, which were even greater than those between MSW and women, suggest this population has the greatest amount of unmet needs, the researchers concluded. “Acknowledging these differences when planning/administering care can help narrow disparities,” they wrote.

The MammaPrint 70-gene signature has similar prognostic performance in women with early-stage invasive lobular carcinoma (ILC) and invasive ductal carcinoma (IDC) and may help guide chemotherapy decisions, according to an exploratory analysis of the MINDACT trial reported at the 12th European Breast Cancer Conference.

ILC is enriched with features indicating low proliferative activity, noted investigator Otto Metzger, MD, of the Dana Farber Cancer Institute in Boston.

“Data from retrospective series have indicated no benefit with adjuvant chemotherapy for patients diagnosed with early-stage ILC,” he said. “It’s fair to say that chemotherapy decisions for patients with ILC remain controversial.”

With this in mind, Dr. Metzger and colleagues analyzed data for 5,313 women who underwent surgery for early-stage breast cancer (node-negative or up to three positive lymph nodes) and were risk-stratified to receive or skip adjuvant chemotherapy based on both clinical risk and the MammaPrint score for genomic risk. Fully 44% of women with ILC had discordant clinical and genomic risks.

With a median follow-up of 8.7 years, the 5-year rate of distant metastasis–free survival among all patients classified as genomic high risk was 92.1% in women with IDC and 88.1% in women with ILC, with overlapping 95% confidence intervals. Rates of distant metastasis–free survival for patients with genomic low risk were 96.4% in women with IDC and 96.6% in women with ILC, again with confidence intervals that overlapped.

The pattern was essentially the same for overall survival, and results carried over into 8-year outcomes as well.

“We believe that MammaPrint is a clinically useful test for patients diagnosed with ILC,” Dr. Metzger said. “There are similar survival outcomes for ILC and IDC when matched by genomic risk. This is an important message.”

It should be standard to omit chemotherapy for patients who have ILC classified as high clinical risk but low genomic risk by MammaPrint, Dr. Metzger recommended. “By contrast, MammaPrint should facilitate chemotherapy treatment decisions for patients diagnosed with ILC and high-risk MammaPrint,” he said.
 

Prognostic, but predictive?

“This is a well-designed prospective multicenter trial and provides the best evidence to date that MammaPrint is an important prognostic tool for ILC,” Todd Tuttle, MD, of University of Minnesota in Minneapolis, said in an interview.

Dr. Tuttle said he mainly uses the MammaPrint test and the OncoType 21-gene recurrence score to estimate prognosis for his patients with ILC.

These new data establish that MammaPrint is prognostic in ILC, but the value of MammaPrint’s genomic high risk result for making the decision about chemotherapy is still unclear, according to Dr. Tuttle.

“I don’t think we know whether MammaPrint can predict the benefit of chemotherapy for patients with stage I or II ILC,” he elaborated. “We need further high-quality studies such as this one to determine the best treatment strategies for ILC, which is a difficult breast cancer.”
 

Study details

Of the 5,313 patients studied, 487 had ILC (255 classic and 232 variant) and 4,826 had IDC according to central pathology assessment, Dr. Metzger reported.

MammaPrint classified 39% of the IDC group and 16% of the ILC group (10% of those with classic disease and 23% of those with variant disease) as genomically high risk for recurrence. The Adjuvant! Online tool classified 48.3% of ILC and 51.5% of IDC patients as clinically high risk.

Among the 44% of women with ILC having discordant genomic and clinical risk, discordance was usually due to the combination of low genomic risk and high clinical risk, seen in 38%.

The curves for 5-year distant metastasis–free survival stratified by genomic risk essentially overlapped for the IDC and ILC groups. Furthermore, there was no significant interaction of histologic type and genomic risk on this outcome (P = .547).

The 5-year rate of overall survival among women with genomic high risk was 95.6% in the IDC group and 93.5% in the ILC group. Among women with genomic low risk, 5-year overall survival was 98.1% in the IDC group and 97.7% in the ILC group, again with overlapping confidence intervals within each risk category.

The study was funded with support from the Breast Cancer Research Foundation. Dr. Metzger disclosed consulting fees from AbbVie, Genentech, Roche, and Pfizer. Dr. Tuttle disclosed no conflicts of interest.

Dr. Tuttle said he mainly uses the MammaPrint test and the OncoType 21-gene recurrence score to estimate prognosis for his patients with ILC.

These new data establish that MammaPrint is prognostic in ILC, but the value of MammaPrint’s genomic high risk result for making the decision about chemotherapy is still unclear, according to Dr. Tuttle.

“I don’t think we know whether MammaPrint can predict the benefit of chemotherapy for patients with stage I or II ILC,” he elaborated. “We need further high-quality studies such as this one to determine the best treatment strategies for ILC, which is a difficult breast cancer.”
 

Study details

Of the 5,313 patients studied, 487 had ILC (255 classic and 232 variant) and 4,826 had IDC according to central pathology assessment, Dr. Metzger reported.

MammaPrint classified 39% of the IDC group and 16% of the ILC group (10% of those with classic disease and 23% of those with variant disease) as genomically high risk for recurrence. The Adjuvant! Online tool classified 48.3% of ILC and 51.5% of IDC patients as clinically high risk.

Among the 44% of women with ILC having discordant genomic and clinical risk, discordance was usually due to the combination of low genomic risk and high clinical risk, seen in 38%.

The curves for 5-year distant metastasis–free survival stratified by genomic risk essentially overlapped for the IDC and ILC groups. Furthermore, there was no significant interaction of histologic type and genomic risk on this outcome (P = .547).

The 5-year rate of overall survival among women with genomic high risk was 95.6% in the IDC group and 93.5% in the ILC group. Among women with genomic low risk, 5-year overall survival was 98.1% in the IDC group and 97.7% in the ILC group, again with overlapping confidence intervals within each risk category.

The study was funded with support from the Breast Cancer Research Foundation. Dr. Metzger disclosed consulting fees from AbbVie, Genentech, Roche, and Pfizer. Dr. Tuttle disclosed no conflicts of interest.
