ASCO goes ahead online, as conference center is used as hospital
Traditionally at this time of year, everyone working in cancer turns their attention toward Chicago, and 40,000 or so travel to the city for the annual meeting of the American Society of Clinical Oncology (ASCO).
Not this year.
The McCormick Place convention center has been converted to a field hospital to cope with the ongoing COVID-19 pandemic. The cavernous meeting halls have been filled with makeshift wards with 750 acute care beds, as shown in a tweet from Toni Choueiri, MD, chief of genitourinary oncology at the Dana Farber Cancer Center in Boston.
But the annual meeting is still going ahead, having been transferred online.
“We have to remember that even though there’s a pandemic going on and people are dying every day from coronavirus, people are still dying every day from cancer,” Richard Schilsky, MD, PhD, chief medical officer at ASCO, told Medscape Medical News.
“This pandemic will end, but cancer will continue, and we need to be able to continue to get the most cutting edge scientific results out there to our members and our constituents so they can act on those results on behalf of their patients,” he said.
The ASCO Virtual Scientific Program will take place over the weekend of May 30-31.
“We’re certainly hoping that we’re going to deliver a program that features all of the most important science that would have been presented in person in Chicago,” Schilsky commented in an interview.
Most of the presentations will be prerecorded and then streamed, which “we hope will mitigate any of the technical glitches that could come from trying to do a live broadcast of the meeting,” he said.
There will be 250 oral and 2500 poster presentations in 24 disease-based and specialty tracks.
The majority of the abstracts will be released online on May 13. The majority of the on-demand content will be released on May 29. Some of the abstracts will be highlighted at ASCO press briefings and released on those two dates.
But some of the material will be made available only on the weekend of the meeting. The opening session, plenaries featuring late-breaking abstracts, special highlights sessions, and other clinical science symposia will be broadcast on Saturday, May 30, and Sunday, May 31 (the schedule for the weekend program is available on the ASCO meeting website).
Among the plenary presentations are some clinical results that are likely to change practice immediately, Schilsky predicted. These include data to be presented in the following abstracts:
- Abstract LBA4 on the KEYNOTE-177 study comparing immunotherapy using pembrolizumab (Keytruda, Merck & Co) with chemotherapy in patients with metastatic colorectal cancer whose tumors show microsatellite instability or mismatch repair deficiency;
- Abstract LBA5 on the ADAURA study exploring osimertinib (Tagrisso, AstraZeneca) as adjuvant therapy after complete tumor reseaction in patients with early-stage non–small cell lung cancer whose tumors are EGFR mutation positive;
- Abstract LBA1 on the JAVELIN Bladder 100 study exploring maintenance avelumab (Bavencio, Merck and Pfizer) with best supportive care after platinum-based first-line chemotherapy in patients with advanced urothelial carcinoma.
However, some of the material that would have been part of the annual meeting, which includes mostly educational sessions and invited talks, has been moved to another event, the ASCO Educational Program, to be held in August 2020.
“So I suppose, in the grand scheme of things, the meeting is going to be compressed a little bit,” Schilsky commented. “Obviously, we can’t deliver all the interactions that happen in the hallways and everywhere else at the meeting that really gives so much energy to the meeting, but, at this moment in our history, probably getting the science out there is what’s most important.”
Virtual exhibition hall
There will also be a virtual exhibition hall, which will open on May 29.
“Just as there is a typical exhibit hall in the convention center,” Schilsky commented, most of the companies that were planning to be in Chicago have “now transitioned to creating a virtual booth that people who are participating in the virtual meeting can visit.
“I don’t know exactly how each company is going to use their time and their virtual space, and that’s part of the whole learning process here to see how this whole experiment is going to work out,” he added.
Unlike some of the other conferences that have gone virtual, in which access has been made available to everyone for free, registration is still required for the ASCO meeting. But the society notes that the registration fee has been discounted for nonmembers and has been waived for ASCO members. Also, the fee covers both the Virtual Scientific Program in May and the ASCO Educational Program in August.
Registrants will have access to video and slide presentations, as well as discussant commentaries, for 180 days.

Expert discusses red flags for interstitial lung disease in pediatric rheumatology
MAUI, HAWAII – Anti-Ro52 autoantibodies are the latest and most potent of the autoantibody predictors of interstitial lung disease (ILD) discovered in patients with juvenile dermatomyositis, Anne M. Stevens, MD, PhD, said at the 2020 Rheumatology Winter Clinical Symposium.
In addition to detailing the autoantibody red flags for ILD in juvenile dermatomyositis (JDM), she called for “hypervigilance” in patients with systemic juvenile idiopathic arthritis (SJIA) who exhibit any of a series of risk factors for ILD.
“Most of the lung disease in kids with systemic JIA is asymptomatic until very late, but it can be reversible if we treat it. So it’s worth finding and monitoring and giving everyone PCP [pneumocystis pneumonia] prophylaxis, because they have a high incidence of PCP if they have any of those risk factors,” observed Dr. Stevens, a pediatric rheumatologist at the University of Washington, Seattle, and senior director for the adaptive immunity research program at Janssen Pharmaceuticals.
Autoantibodies predict ILD in JDM
Dr. Stevens highlighted recent work by Sara Sabbagh, DO, of the National Institute of Arthritis and Musculoskeletal and Skin Diseases and coinvestigators in the Childhood Myositis Heterogeneity Collaborative Study Group. They reported the presence of anti-Ro52 autoantibodies in 14% of a cohort of 302 patients with JDM as well as in 12% of 25 patients with juvenile polymyositis and in 18% of 44 youths with an overlap of juvenile connective tissue disease and myositis. In addition, 13% of patients were positive for autoantibodies previously identified as being associated with ILD in these forms of juvenile myositis: Namely, 9% of the cohort were positive for antimelanoma differentiation–associated protein 5 (anti-MDA5) autoantibodies, and antiaminoacyl tRNA synthestase (anti-Jo-1) autoantibodies were present in 4%.
A total of 33 of the 371 juvenile myositis patients had ILD based upon CT imaging, chest X-ray, dyspnea on exertion, and/or biopsy. Most patients with anti-Ro52 also had other autoantibodies associated with ILD. Indeed, 31% of patients with anti-MDA5 autoantibodies also had anti-Ro52, as did 64% of those with anti-Jo-1. After controlling for the presence of these other myositis-specific autoantibodies, auto-Ro52 autoantibodies were independently associated with ILD, which was present in 36% of those with and just 4% of those without anti-Ro52 autoantibodies.
Importantly, if a patient with JDM or another form of juvenile myositis had both anti-Ro52 and another myositis-specific autoantibody, the risk for ILD rose dramatically, climbing to 70% in patients with anti-Ro52 and anti-MDA5 autoantibodies, and to 100% in those who were both anti-Ro52- and anti-Jo-1 positive.
Patients with anti-Ro52 autoantibodies had a worse prognosis, with more severe and chronic disease, Dr. Stevens noted.
Novel potential treatment for ILD in JDM: JAK inhibitors
Standard treatment of ILD in JDM in all cases includes high-dose pulsed corticosteroids, intravenous immunoglobulin (IVIG), and either methotrexate or mycophenolate mofetil. Consideration should be given to adding cyclosporine, particularly when a macrophage activation syndrome component is present. In addition, several exciting recent lines of evidence suggest a potential role for Janus kinase (JAK) inhibitors in the subset of JDM patients with anti-MDA5 autoantibody-positive disease, according to Dr. Stevens.
For one, Dr. Sabbagh and colleagues have reported impressive success with the use of the JAK 1/3 inhibitor tofacitinib (Xeljanz) in two patients with anti-MDA5 autoantibody-positive refractory JDM with ILD. Both patients experienced moderate clinical improvement in disease activity in their skin, muscles, and other target organs. But particularly striking was what the investigators termed the “remarkable” improvement in ILD, including near-resolution of abnormal findings on high-resolution CT imaging and a more robust performance on pulmonary function testing.
Both of these hitherto treatment-refractory patients were able to wean or discontinue their immunosuppressive medications. The patients’ elevated blood interferon-response gene signature improved significantly in response to tofacitinib, and their problematic upregulation of STAT1 phosphorylation of CD4+ T cells and monocytes stimulated with interferon-gamma was tamed, dropping to levels typically seen in healthy individuals.
Also, French pediatric rheumatologists have identified key phenotypic and cytokine differences between 13 patients with JDM or juvenile overlap myositis who were anti-MDA5 autoantibody positive at presentation and 51 others who were not. The anti-MDA5 autoantibody–positive group had a higher frequency of ILD, arthritis, skin ulcerations, and lupus features, but milder muscle involvement than did the anti-MDA5 autoantibody–negative group. The anti-MDA5 autoantibody–positive patients demonstrated enhanced interferon-alpha signaling based upon their significantly higher serum interferon-alpha levels, compared with the anti-MDA5-negative group, and those levels decreased following treatment with improvement in symptoms.
The French investigators proposed that interferon-alpha may constitute a novel therapeutic target in the subgroup of patients with severe, refractory juvenile myositis and anti-MDA5 autoantibodies – and, as it happens, it’s known that JAK inhibitors modulate the interferon pathway.
Risk factors for ILD in SJIA
In the past half-dozen years or so, pediatric rheumatologists have become increasingly aware of and concerned about a new development in SJIA: the occurrence of comorbid ILD. This is a poor-prognosis disease: In a cohort from the United Kingdom, 5-year mortality from the time of diagnosis was 41%, fully 40-fold higher than in patients with SJIA only.
Patient cohorts with SJIA and ILD have unusual clinical and laboratory features that aren’t part of the typical picture in SJIA. These include acute clubbing, lymphopenia, a fixed pruritic rash, unexplained abdominal pain, peripheral eosinophilia, facial swelling, and an increased ferritin level, a hallmark of acute macrophage activation syndrome. Onset of SJIA before 2 years of age is another red flag associated with increased risk for ILD. So is trisomy 21, which is up to 50 times more prevalent in patients with SJIA and ILD than in the general population or in patients with SJIA only. Another clue is an adverse reaction to tocilizumab (Actemra).
Any of these findings warrant hypervigilance: “Be on high alert and monitor these patients for ILD much more closely,” Dr. Stevens advised.
This means ordering a CT scan, prescribing PCP prophylaxis, and regularly measuring pulmonary function, admittedly a challenge in children under 7 years old. In these younger kids, practical solutions include measuring their oxygen saturation before and after running around the room to see if it drops. A 6-minute walk test and sleep oximetry are other options.
The explanation for the abrupt arrival of ILD as part of the picture in SJIA during the past decade remains unclear. The timing coincides with a major advance in the treatment of SJIA: the arrival of biologic agents blocking interleukin-1 and -6. Could this be a serious treatment side effect?
“It’s all association so far, and we’re not really sure why we’re seeing this association. Is it because we’re using a lot [fewer] corticosteroids now, and maybe those were preventing lung disease in the past?” Dr. Stevens speculated.
At this point, she and her fellow pediatric rheumatologists are awaiting further evidence before discussing a curb in their use of IL-1 or -6 inhibitors in patients with SJIA.
“These drugs have turned around the lives of kids with SJIA. They used to suffer through all our ineffective treatments for years, with terrible joint destruction and a pretty high mortality rate. These are great drugs for this disease, and we certainly don’t want to limit them,” she said.
Dr. Stevens reported research collaborations with Kineta and Seattle Genetics in addition to her employment at Janssen Pharmaceuticals.

The anti-MDA5 autoantibody–positive group had a higher frequency of ILD, arthritis, skin ulcerations, and lupus features, but milder muscle involvement than did the anti-MDA5 autoantibody–negative group. The anti-MDA5 autoantibody–positive patients demonstrated enhanced interferon-alpha signaling based upon their significantly higher serum interferon-alpha levels, compared with the anti-MDA5-negative group, and those levels decreased following treatment with improvement in symptoms.
The French investigators proposed that interferon-alpha may constitute a novel therapeutic target in the subgroup of patients with severe, refractory juvenile myositis and anti-MDA5 autoantibodies – and, as it happens, it’s known that JAK inhibitors modulate the interferon pathway.
Risk factors for ILD in SJIA
In the past half-dozen years or so, pediatric rheumatologists have become increasingly aware of and concerned about a new development in SJIA: the occurrence of comorbid ILD. This is a poor-prognosis disease: In a cohort from the United Kingdom, 5-year mortality from the time of diagnosis was 41%, fully 40-fold higher than in patients with SJIA only.
Patient cohorts with SJIA and ILD have unusual clinical and laboratory features that aren’t part of the typical picture in SJIA. These include acute clubbing, lymphopenia, a fixed pruritic rash, unexplained abdominal pain, peripheral eosinophilia, facial swelling, and an increased ferritin level, a hallmark of acute macrophage activation syndrome. Onset of SJIA before 2 years of age is another red flag associated with increased risk for ILD. So is trisomy 21, which is up to 50 times more prevalent in patients with SJIA and ILD than in the general population or in patients with SJIA only. Another clue is an adverse reaction to tocilizumab (Actemra).
Any of these findings warrant hypervigilance: “Be on high alert and monitor these patients for ILD much more closely,” Dr. Stevens advised.
This means ordering a CT scan, prescribing PCP prophylaxis, and regularly measuring pulmonary function, admittedly a challenge in children under 7 years old. In these younger kids, practical solutions include measuring their oxygen saturation before and after running around the room to see if it drops. A 6-minute walk test and sleep oximetry are other options.
The explanation for the abrupt arrival of ILD as part of the picture in SJIA during the past decade remains unclear. The timing coincides with a major advance in the treatment of SJIA: the arrival of biologic agents blocking interleukin-1 and -6. Could this be a serious treatment side effect?
“It’s all association so far, and we’re not really sure why we’re seeing this association. Is it because we’re using a lot [fewer] corticosteroids now, and maybe those were preventing lung disease in the past?” Dr. Stevens speculated.
At this point, she and her fellow pediatric rheumatologists are awaiting further evidence before discussing a curb in their use of IL-1 or -6 inhibitors in patients with SJIA.
“These drugs have turned around the lives of kids with SJIA. They used to suffer through all our ineffective treatments for years, with terrible joint destruction and a pretty high mortality rate. These are great drugs for this disease, and we certainly don’t want to limit them,” she said.
Dr. Stevens reported research collaborations with Kineta and Seattle Genetics in addition to her employment at Janssen Pharmaceuticals.

Cell and gene research raise hopes for recessive dystrophic EB treatments
LONDON – .
“I think there is a palpable sense that we are close to some breakthroughs for EB,” which may include “a cure for this intractable disease,” said Jouni Uitto, MD, PhD, in welcoming delegates to the meeting, held in January 2020.
Dr. Uitto, professor of dermatology and cutaneous biology, and biochemistry and molecular biology, at Sidney Kimmel Medical College, Philadelphia, said that the “breadth of academia-based basic science has been tremendous over the past 3 decades. We can now identify 21 different genes harboring mutations associated with different EB phenotypes, and we have a pretty good understanding how those mutations actually explain the phenotypic spectrum of different forms of EB.”
Importantly, “there are now perhaps as many as a dozen different clinical trials that are in the early stages of trying to find a permanent cure for this disease,” Dr. Uitto said, with some that are looking at fixing the underlying defect once and for all, or at the very least, counteracting subsequent complications. “The spectrum varies from attempting to enhance wound healing to gene repair, gene replacement, protein replacement therapies, cell-based therapies. There is a whole spectrum of often complementary approaches that we believe will lead to a cure and treatment for this disease. We look forward to developing therapies which will be helpful to the benefit of all the patients with EB,” said Dr. Uitto, who is also chair of the department of dermatology and cutaneous biology at Sidney Kimmel Medical College.
EB research is gathering ‘momentum’
John McGrath, MD, professor of molecular dermatology, King’s College, London, chaired a session on the latest in cell manipulation research and made the following comment: “A few years ago, we were making progress, but we were chatting about a lot of the same things; but now, suddenly there seems to be momentum, re-energy, rediscovery, real progress.”
Dr. McGrath noted that gene and cell research, and preclinical development, were culminating in clinical trials and potentially products that could change the way clinicians thought about managing patients with EB. “That prospect of getting closer and closer to real treatments, and maybe even a cure” is becoming more of a reality, he said.
Dr. McGrath is also head of the genetic skin disease group at King’s College London, and an honorary consultant dermatologist at St. John’s Institute of Dermatology, part of the Guy’s and St. Thomas’ NHS Foundation Trust in London. He has been a principal investigator for clinical trials of fibroblast cell therapy and allogeneic intravenous mesenchymal stromal cells (MSCs) therapy.
“It has been a joy for me to see the benefits of those clinical trials. There is nothing like it as an investigator when you see an intervention make a difference to a patient,” Dr. McGrath said. “For me, it was just a real eye opener when I saw the skin changes in a child that received intravenous allogeneic MSCs. The skin changed dramatically, it went from red and inflamed to calm and pink, [giving a] first glimpse into something that might be reversible, treatable, not just papering over the cracks.”
Correcting the genetic defect
The most severe form of RDEB is caused by mutations in COL7A1, the gene for collagen type 7 (COL7), the major connective component of the skin, anchoring the epidermis to the dermis. Its absence results in skin that can be so fragile it has been likened to the wings of a butterfly and results in severe blistering after very little trauma.
There is a lot of research on how to correct the underlying genetic defect, either by replacing COL7A1 entirely, repairing the gene, or editing the gene so that COL 7 can be produced in situ and prevent the formation of wounds and heal those that might already be present.
“The excitement is obvious,” said Jakub Tolar, MD, PhD, professor in the department of pediatrics, blood and marrow transplantation, and dean of the University of Minnesota Medical School, Minneapolis, who chaired a session on gene and gene manipulation therapies. “If one can go and correct that information, it follows that everything else is going to be okay,” he said. “Only it’s not. I think that it’s pretty clear that more than gene correction is needed.”
Some of the approaches to replace the faulty gene discussed at the meeting involved taking skin biopsy samples from a healthy area of skin from a patient with RDEB, isolating specific skin cells (fibroblasts, keratinocytes, or both), transferring a healthy copy of the COL7A1 gene into those cells – then expanding the population to form sheets of cells that can be grafted onto the wounds of the same patient.
Clinical trials of gene therapy for RDEB
Clinical trials with these novel gene-corrected, tissue-engineered grafts have already started, including EBGraft, a phase 1/2 open, nonrandomized, proof-of-concept trial using genetically corrected sheets of fibroblasts and keratinocytes, conducted by Alain Hovnanian, MD, PhD, Necker-Enfants Malades Hospital in Paris, and associates.
Then there is the phase 3 VIITAL trial being conducted at Stanford (Calif.) University by Jean Tang, MD, PhD, and colleagues. Recruitment in this open trial, which will enroll 10-15 patients with RDEB, has just started. The aim of the study is to investigate the efficacy and safety of EB-101, an autologous cell therapy that corrects COL7A1 in keratinocytes.
Positive findings from a phase 1/2 study with EB-101 were presented in a poster at the meeting by Emily Gorell, DO, a postdoctoral medical fellow in dermatology, at Stanford University and her associates. The trial included seven patients with RDEB who were treated and followed for 3 to 6 years. Data from that study showed that there were no serious adverse events and 95% of patients’ wounds that were treated (36/38) were healed by at least 50%, based on an Investigator Global Assessment at 6 months. In comparison, none of the untreated wounds had healed by that time point. “There was evidence of C7 [collagen 7] restoration at 2 years in two participants,” and wound healing was associated with both reduced pain and itch, the investigators wrote in the poster.
Another approach to this so-called ‘ex-vivo’ gene therapy is to take the patient’s cells via a small skin biopsy, genetically modify them, expand the population of these modified cells, and then inject them back into the patient. This approach was described by Peter Marinkovich, MD, of the department of dermatology at Stanford University, during an oral presentation and in a poster at the meeting.
Dr. Marinkovich discussed the results of an ongoing phase 1/2 study in which six subjects with RDEB – five adults and one child – were treated intradermally with genetically modified fibroblasts in a preparation currently known as FCX-007.
“Before we had to graft the cells, take the patients into the OR [operating room], with the risks of general anesthesia, but here we don’t have to take the patients to the OR, we just take them into the hospital for a day, inject their wounds and then send them on their way,” Dr. Marinkovich said. Interim findings show that the patients have tolerated the therapy very well up to 52 weeks, he noted.
A greater percentage of wounds were healed by more than 50% following treatment with FCX-007 than those left untreated at weeks 4 (80% versus 20%), 12 (90% versus 44%), 25 (75% versus 50%), and 52 (83% versus 33%).
These results have been used to inform the design of the upcoming phase 3 study, DEFI-RDEB. The multicenter intrapatient randomized, controlled, open-label study is evaluating FCX-007 in the treatment of persistent nonhealing wounds in about 20 people with RDEB.
The promise of ‘off-the-shelf’ topical gene therapy
Another study Dr. Marinkovich is involved with is a phase 1/2 study of beremagene geperpavec (B-VEC), an “in-vivo” gene therapy. B-VEC is a topically administered therapy containing a replication-deficient, nonintegrating viral vector that contains two functional COL7A1 genes. The concept is that, when applied directly onto the skin, the virus gets into the skin and carries with it the healthy gene copies; these get taken up by the skin cells, which then produce COL7.
Initially, two patients with generalized severe RDEB were studied. B-VEC was applied to one of two wounds and a placebo to the other wound in each patient. Another four patients were then enrolled and studied for 3 months. Nine of 10 wounds closed completely after initial administration of B-VEC, with an average time to 100% wound closure of 17.4 days. The average duration of wound closure has been 113 days so far.
“One chronic wound that was originally open for over 4 years closed completely following B-VEC readministration. The wound has remained closed for 100 days,” Dr. Marinkovich and associates reported in a poster at the meeting. A postimaging study showed that COL7 was being produced from 48 hours to up to 90 days later.
“I’m really excited about this type of therapy,” Dr. Marinkovich said during an oral presentation. Unlike the ex-vivo gene therapy approach, where each patient’s cells have to be taken by a biopsy, altered, engineered, and expanded, which takes specialized facilities that can vary by country and location, this in-vivo gene therapy can be considered an “off-the shelf” treatment that can be shipped all over the world and could reach many patients. “It’s another weapon in our armamentarium against this deadly disease that we are all fighting against together,” Dr. Marinkovich added.

Schulze Family Foundation (RMSFF). He disclosed receiving honoraria or consultation fees from Ticeba/RHEACELL GmbH and Taiga Biosciences.

REPORTING FROM EB 2020
Two rare neurologic conditions linked to COVID-19
A 50-year-old man developed Miller Fisher syndrome and a 39-year-old man developed polyneuritis cranialis. Both are variants of Guillain-Barré syndrome (GBS), which physicians in China and Italy also linked to COVID-19 infection, as previously reported by Medscape Medical News.
In both cases, physicians made the diagnoses based on abnormal eye examinations. The two patients responded to treatment and improved over 2 weeks, with only the 50-year-old featuring residual symptoms of anosmia and ageusia.
The report was published online April 17 in Neurology.
The 50-year-old man was admitted to an emergency room with a temperature of 99.9°F (37.7°C). He reported 2 days of vertical diplopia, perioral paresthesias, and gait instability. His neurologic examination showed intact cognitive function and language.
Five days earlier he developed a cough, malaise, headache, low back pain, fever, anosmia, and ageusia.
His neuro-ophthalmologic examination showed right hypertropia in all fields of gaze, severe limitations to the adduction and downgaze movements of his right eye, and left eye nystagmus on left gaze. These findings were consistent with right internuclear ophthalmoparesis and right fascicular oculomotor palsy.
He responded to intravenous (IV) immunoglobulin therapy and was discharged home 2 weeks after admission.
The 39-year-old man was admitted to the emergency room with acute onset diplopia and ageusia. Three days earlier he had presented with diarrhea, a low-grade fever and in generally poor condition, without any headache, respiratory symptoms, or dyspnea.
He showed esotropia of 10 prism diopters at distance and 4 prism diopters at near, severe abduction deficits in both eyes, and fixation nystagmus, with the upper gaze more impaired, all consistent with bilateral abducens palsy.
The patient was discharged home and treated symptomatically with acetaminophen and telemedicine monitoring “due to a complete hospital saturation with COVID-19 patients,” wrote the researchers, led by Consuelo Gutiérrez-Ortiz, MD, PhD, Hospital Universitario Príncipe de Asturias, Madrid, Spain.
Two weeks later, he had made a complete neurologic recovery with no ageusia, complete eye movements, and normal deep tendon reflexes.
“Fisher syndrome and polyneuritis cranialis in these two patients with the SARS-CoV-2 infection could be simply coincidental. However, taking into account the temporal relationship, we feel that COVID-19 might have been responsible for the development of these two neurological pictures,” the authors noted.

Want to keep cancer patients and providers safe during the pandemic? Here’s how
according to the authors of a special feature article in the Journal of the National Comprehensive Cancer Network.
Prescreening, telemedicine, and limiting procedures top the authors’ list of 10 recommendations for ensuring patient safety in U.S. oncology practices. Assuring appropriate personal proctective equipment (PPE), encouraging telecommuting, and providing wellness/stress management are a few of the ways to look out for health care worker safety during the crisis.
These recommendations were drafted to provide guidance during the rapidly evolving global pandemic that, in some cases, has deluged health care delivery systems and strained the ability of providers to assure safe and effective care, said lead author Pelin Cinar, MD, of the Hellen Diller Family Comprehensive Cancer Center at the University of California, San Francisco.
“I think we have been so overwhelmed that sometimes it’s difficult to get organized in our thought processes,” Dr. Cinar said in an interview. “So this [article] was really trying to provide some structure to each of the different steps that we should be addressing at minimum.”
Screening patients
Prescreening systems are a critical first step to ensure cancer centers are helping control community spread of the virus, according to the article. Whether done by phone or online, prescreening 1-2 days before a patient’s visit can help identify COVID-19 symptoms and exposure history, guiding whether patients need to be evaluated, monitored, or referred to an ED.
Next, screening clinics can help ensure cancer patients with COVID-19 symptoms are evaluated and tested in a unit with dedicated staff, according to the article.
“If symptomatic patients present to the cancer center for treatment after a negative prescreening assessment, they must be provided with a mask and directed to a screening clinic for evaluation and potential testing before moving forward with any cancer-directed therapy,” the article states.
Telemedicine and treatment
Telemedicine visits should be done whenever possible to avoid in-person visits, according to the article. Dr. Cinar said that her center, like other cancer centers, has seen a major uptick in these visits, which are typically done over video. In February, there were a total of 232 video visits at her center, which jumped to 1,702 in March, or an approximate 600% increase.
“Even though we had a relatively robust presence [before the pandemic], we still weren’t at a level where we are now,” Dr. Cinar said.
When it comes to cancer treatment, surgeries and procedures should be limited to essential or urgent cases, and, if possible, chemotherapy and systemic therapy regimens can be modified to allow for fewer visits to the cancer center or infusion center, according to the article.
Transitions to outpatient care can help further reduce the need for in-person visits, while intervals between scans can be increased, or biochemical markers can be used instead of scans.
Protecting providers
Health care workers providing cancer care should be assured appropriate PPE, and websites or other centralized resources should be in place to make sure workers are aware of current PPE guidelines and changes in workflow, according to the article.
The authors note that daily screening tools or temperature checks of symptomatic workers can help decrease the risk of exposure to others. The authors also recommend establishing clear rules for when health care workers with suspected or confirmed COVID-19 should be staying at home and returning to the job.
Telecommuting should be encouraged, with limited staff participating in onsite rotations to further reduce exposure risks, the article states.
Anxiety, insomnia, and distress have been reported among frontline health care workers managing patients with COVID-19, according to the article, which recommends wellness and stress management resources be available as an “invaluable resource” in cancer centers.
“We have to take care of ourselves to be able to take care of others,” Dr. Cinar said. “With PPE, you’re physically protecting yourself, while self-care, stress management, and wellness are also a big component of protecting ourselves.”
The report by Dr. Cinar and colleagues was an invited article from the NCCN Best Practices Committee. One coauthor reported relationships with Abbvie, Adaptive Biotechnologies, Aduro, and several other companies. Dr. Cinar and the remaining authors said they had no relevant conflicts of interest.

FROM THE JOURNAL OF THE NATIONAL COMPREHENSIVE CANCER NETWORK
A case of neutrophilic eccrine hidradenitis attributed to HIV treatment
arising in an affected patient, Jessica Kalen, MD, advised during a virtual meeting held by the George Washington University department of dermatology.
The virtual meeting included presentations that had been slated for the annual meeting of the American Academy of Dermatology, which was canceled because of the COVID-19 pandemic.
In a presentation entitled, “When HAART [highly active antiretroviral therapy] Hurts,” Dr. Kalen, a dermatology resident at the university, presented a case report involving a 65-year-old man who presented with juicy red edematous papules and plaques on his scalp and ears. He was on the three-drug combination of rilpivirine (a non-nucleoside reverse transcriptase inhibitor), and the NRTIs tenofovir, and emtricitabine (Odefsey) for treatment of HIV infection, which was well controlled, with no detectable viral load.
The patient was also on insulin detemir for diabetes; pravastatin, amlodipine, and lisinopril for hypertension; and episodic acyclovir for recurrent herpes simplex outbreaks. However, none of those drugs has been associated with NEH. In contrast, Dr. Kalen found three published case reports describing a link between NRTIs and NEH.
Lesional biopsy of her patient showed the classic features of NEH: a dermal neutrophilic infiltrate surrounding the eccrine secretory coils and ducts, with vacuolar degeneration that spared the acrosyringium.
The most common causes of NEH, a rare dermatologic disorder first described in 1982, are hematologic malignancies and some of the chemotherapeutic agents used in treating them. Particularly prominent are acute myelogenous leukemia and cytarabine, which are often prescribed for that cancer. Carbamazepine, granulocyte-colony stimulating factor, and BRAF inhibitors have also been associated with NEH.
The pathogenesis of NEH is not fully worked out; however, NRTIs are secreted via eccrine structures, and that close contact could potentially promote an environment favoring inflammation and destruction of the eccrine coils. Also, NRTIs inhibit DNA polymerase, as does cytarabine, Dr. Kalen noted.
Her patient’s NEH was treated with triamcinolone. His skin condition resolved completely while he remained on NRTI therapy, with no relapses to date.
Dr. Kalen reported having no financial conflicts regarding her presentation.

FDA approves Koselugo for pediatric neurofibromatosis treatment
The Food and Drug Administration has approved selumetinib (Koselugo) for the treatment of pediatric patients aged 2 years and older with type 1 neurofibromatosis (NF1) with symptomatic, inoperable plexiform neurofibromas.
FDA approval was based on results from the phase 2 SPRINT Stratum 1 trial, in which 50 patients with NF1 received selumetinib as twice-daily oral monotherapy. Of this group, 33 (66%) patients had a partial response of at least a 20% reduction in tumor volume. There were no complete responses, according to a press release.
The most common adverse events were vomiting, rash, abdominal pain, diarrhea, nausea, dry skin, fatigue, musculoskeletal pain, pyrexia, rash acneiform, stomatitis, headache, paronychia, and pruritus. Dose interruptions, dose reductions, and permanent drug discontinuation occurred in 80%, 24%, and 12% of patients, respectively.
Serious adverse reactions included cardiomyopathy, ocular toxicity, gastrointestinal toxicity, increased creatinine phosphokinase, and increased vitamin E levels and risk of bleeding, according to the press release.
“Previously, there were no medicines approved for this disease. This approval has the potential to change how symptomatic, inoperable NF1 plexiform neurofibromas are treated and provides new hope to these patients,” Roy Baynes, MD, PhD, senior vice president, head of global clinical development, and chief medical officer of Merck Research Laboratories, said in the press release.

First case of COVID-19 presenting as Guillain-Barré reported
The patient was a 61-year-old woman returning home from Wuhan during the pandemic.
“GBS is an autoimmune neuropathy, which could be triggered by various infections,” said corresponding author Sheng Chen, MD, PhD, of Shanghai Jiao Tong University School of Medicine in China. However, “Our single case report only suggests a possible association between GBS and SARS-CoV-2 infection. It may or may not have a causal relationship,” Dr. Chen noted.
The case study was published online April 1 in Lancet Neurology.
GBS presentation
The female patient returned from Wuhan on January 19 but denied having any fever, cough, chest pain, or diarrhea. She presented on January 23 with acute weakness in both legs and severe fatigue that progressed.
At presentation, temperature was normal, oxygen saturation was 99% on room air, and the patient’s respiratory rate was 16 breaths per minute. She was not tested for SARS-CoV-2 at that point.
A neurologic examination revealed symmetric weakness (Medical Research Council grade 4/5) and areflexia in both legs and feet. The patient’s symptoms had progressed 3 days after admission, and testing revealed decreased sensation to light touch and pinprick.
Admission laboratory test results indicated a low lymphocyte count and thrombocytopenia. Results of nerve conduction studies performed on day 5 of hospitalization were consistent with demyelinating neuropathy.
She was diagnosed with GBS and given intravenous immunoglobulin. On day 8, she developed a dry cough and fever, and a chest CT showed ground-glass opacities in both lungs. At this point, she was tested for SARS-CoV-2, and the results were positive.
The patient was immediately transferred to an isolation room and received supportive care and antiviral drugs. Her condition improved gradually, and her lymphocyte and thrombocyte counts were normal on day 20.
At discharge on day 30, she had normal muscle strength in both arms and legs, and tendon reflexes in both legs and feet had returned. Her respiratory symptoms had resolved as well. A second SARS-CoV-2 test was negative.
Different pattern from Zika
Two relatives of the patient who had been with her during her hospital stay also tested positive for SARS-CoV-2 and were isolated and treated. All of the hospital staff that cared for the patient, including two neurologists and six nurses, tested negative for SARS-CoV-2.
Given the temporal association, a SARS-CoV-2 infection could be responsible for the development of GBS in this patient, the investigators noted. They added that the onset of GBS symptoms overlapped with the period of SARS-CoV-2 infection.
“Hence Guillain-Barré syndrome associated with SARS-CoV-2 might follow the pattern of a parainfectious profile, instead of the classic postinfectious profile, as reported in Guillain-Barré syndrome associated with Zika virus,” the researchers wrote.
“More cases with epidemiological data are necessary to support a causal relationship” between SARS-CoV-2 infection and GBS, said Dr. Chen.
“However, we still suggest physicians who encounter an acute GBS patient from a pandemic area protect themselves carefully and test [for the] virus on admission. If the result is positive, the patient needs to be isolated,” Dr. Chen said.

The patient was a 61-year-old woman returning home from Wuhan during the pandemic.
“GBS is an autoimmune neuropathy, which could be triggered by various infections,” said corresponding author Sheng Chen, MD, PhD, of Shanghai Jiao Tong University School of Medicine in China. However, “Our single case report only suggests a possible association between GBS and SARS-CoV-2 infection. It may or may not have a causal relationship,” Dr. Chen noted.
The case study was published online April 1 in Lancet Neurology.
GBS presentation
The female patient returned from Wuhan on January 19 but denied having any fever, cough, chest pain, or diarrhea. She presented on January 23 with acute weakness in both legs and severe fatigue that progressed.
At presentation, temperature was normal, oxygen saturation was 99% on room air, and the patient’s respiratory rate was 16 breaths per minute. She was not tested for SARS-CoV-2 at that point.
A neurologic examination revealed symmetric weakness (Medical Research Council grade 4/5) and areflexia in both legs and feet. The patient’s symptoms had progressed 3 days after admission, and testing revealed decreased sensation to light touch and pinprick.
Admission laboratory test results indicated a low lymphocyte count and thrombocytopenia. Results of nerve conduction studies performed on day 5 of hospitalization were consistent with demyelinating neuropathy.
She was diagnosed with GBS and given intravenous immunoglobulin. On day 8, she developed a dry cough and fever, and a chest CT showed ground-glass opacities in both lungs. At this point, she was tested for SARS-CoV-2, and the results were positive.
The patient was immediately transferred to an isolation room and received supportive care and antiviral drugs. Her condition improved gradually, and her lymphocyte and thrombocyte counts were normal on day 20.
At discharge on day 30, she had normal muscle strength in both arms and legs, and tendon reflexes in both legs and feet had returned. Her respiratory symptoms had resolved as well. A second SARS-CoV-2 test was negative.

When to suspect calciphylaxis and what to do about it
If the shoe fits a presumptive clinical diagnosis of calciphylaxis, wear it – and don’t assume that ordering imaging studies or histology will make for a better fit or is even necessary.
That was the key message of Karl M. Saardi, MD, during his video presentation at a virtual meeting held by the George Washington University department of dermatology. The virtual meeting included presentations that had been slated for the annual meeting of the American Academy of Dermatology, which was canceled because of the COVID-19 pandemic.
“ said Dr. Saardi, a dermatology resident at Georgetown University in Washington, D.C.
He presented a single-center, retrospective study that underscored the diagnostic challenges posed by calciphylaxis, a condition for which there are no generally accepted clinical, radiographic, or histologic diagnostic criteria.
The rare skin condition is characterized by calcium deposition in small arterioles and capillaries in the skin and subcutaneous tissue. It’s most common in patients with end-stage renal disease who are on dialysis; however, there is also an increasingly recognized nonuremic variant that’s associated with the use of warfarin, chronic steroids, obesity, and possibly with being antiphospholipid antibody positive.
Calciphylaxis is an extremely painful condition – the pain is ischemic in nature – and it’s associated with substantial morbidity as well as a mortality rate that in many series exceeds 50%. Affected individuals typically present with progressive, painful retiform purpura on the legs, belly, buttocks, and other fatty body sites.
Dr. Saardi’s study entailed a retrospective look at the medical records and pathologic reports of 57 patients who underwent skin biopsy for suspected calciphylaxis. Of the 57, 18 had no antecedent imaging studies done during the preceding 3 months; 8 of those 18 (40%), had a confirmatory positive biopsy. A total of 39 patients did have imaging studies, deemed positive for calciphylaxis in 11 cases, which in only 5 of the 11 imaging-positive cases (45%) were subsequently confirmed by positive biopsy.
And finally, of the 28 patients with negative imaging studies, 10 (36%), had a positive biopsy. Those positive biopsy rates, ranging from 36% to 45%, did not differ statistically. Thus, whether an imaging study was positive or negative, or wasn’t even done, made no difference in terms of the ultimate diagnosis.
“You may not need imaging studies, because imaging has often been done before the consultation is requested because people are looking for things like arterial thrombus, cellulitis, [deep vein thrombosis] or something like that,” Dr. Saardi noted. “In our series, the indication was never calciphylaxis, it was always something like pain, infection, swelling, suspected [deep vein thrombosis], things like that.”
The classic signature of calciphylaxis on plain x-ray is net-like calcifications in skin and subcutaneous tissue. In one study, this often-subtle finding was associated with a 830% increased likelihood of a positive biopsy, with a specificity of 90%; however, these x-ray changes were only found in 13 of 29 patients with biopsy-confirmed calciphylaxis.
“It’s really important when you request plain films in these patients to review the images yourself or together with the radiologist because oftentimes the indication for imaging will be very different from what we’re looking for. Radiologists often won’t know to look for this specifically,” Dr. Saardi said.
The classic histopathologic finding is calcification of the small- and medium-sized vessels in the dermis and subcutaneous soft tissue. However, sometimes all that’s present are small intravascular inflammatory thrombi with intimal hyperplasia.
Skin biopsies are not infrequently falsely negative or nondiagnostic. To maximize the utility of the procedure, it’s important to go deep and gather a tissue sample that extends into subcutaneous tissue.
“You need to do a very deep punch or double-punch biopsy,” he said. “Another key is to avoid biopsy if the pretest probability of calciphylaxis is high because a negative biopsy shouldn’t necessarily reassure you or cause you to withhold treatment. And with the concern about pathergy or Koebnerization of the area causing a wound that’s never going to heal, sometimes a biopsy is not needed if the pretest suspicion is high enough.”
Other investigators have shown that the likelihood of an informative biopsy is enhanced by using a calcium stain on the specimen and having an experienced dermatopathologist do the evaluation. Also, the use of a radiographically guided core needle biopsy to ensure that the physician is getting sufficiently deep into subcutaneous fat is now under evaluation.
In addition to plain radiographs, other imaging methods that are sometimes used to evaluate soft-tissue sites for suspected calciphylaxis included CT and ultrasound. Dr. Saardi is particularly intrigued by reports from investigators at Harvard University regarding the utility of nuclear bone scintigraphy; in one study, this form of imaging was positive in 16 of 18 patients with clinically diagnosed calciphylaxis, versus just 1 of 31 controls with end-stage renal disease.
“We’ve started doing this in situations where biopsy is not desirable or feasible at that moment,” he said.
Dr. Saardi reported having no financial conflicts regarding his presentation.

Is There an Association Between Hidradenitis Suppurativa and Fibromyalgia?
To the Editor:
Hidradenitis suppurativa (HS) is a chronic inflammatory condition that affects approximately 1% to 4% of the worldwide population and is 3 times more common in females than in males.1 The condition is characterized by painful inflamed nodules in apocrine gland–bearing regions that can progress to abscesses, sinus tracts, and/or scarring. Hidradenitis suppurativa is associated with intense pain, work disability, and poor quality of life.1
Recent evidence has suggested that HS is an autoimmune disease resulting from dysregulation of the γ-secretase/Notch pathway, leading to stimulation of the toll-like receptor–mediated innate immunity that contributes to occlusion and inflammation of the hair follicle. Additionally, elevated levels of proinflammatory cytokines such as tumor necrosis factor α and IL-17 are seen in HS lesions.2 The autoimmune nature of HS may account for its increased association with other autoimmune disorders such as thyroid disease and potentially with other unexplored conditions such as fibromyalgia.3
Fibromyalgia is a chronic pain condition that primarily affects females and is commonly associated with other autoimmune conditions.4 The primary objective of this retrospective study was to determine the prevalence of fibromyalgia in HS patients and assess if there is an association between HS disease severity and development of fibromyalgia.
We conducted a retrospective chart review of patients at Wake Forest Baptist Medical Center (Winston-Salem, North Carolina) who were 18 years and older and had a diagnosis of both HS and fibromyalgia from January 2008 to November 2018. The primary end point was the prevalence of fibromyalgia in the HS population. The secondary end point was the association of HS disease severity with the development of fibromyalgia. Hidradenitis disease severity was defined according to the number of body areas affected by HS: mild disease involved 1 body area, moderate disease involved 2 body areas, and severe disease involved 3 or more body areas. Patient age, sex, and race also were recorded.
A total of 1356 patients were seen during this time period for HS. The prevalence of fibromyalgia in the HS population was 3.2% (n=44). Ninety-five percent (42/44) of patients with HS and fibromyalgia were women; 22 (50%) patients had severe disease, 12 (27%) had moderate disease, 7 (16%) had mild disease, and 3 (7%) had an unknown number of affected body areas. Fifty-seven percent (25/44) of patients were diagnosed with HS prior to the diagnosis of fibromyalgia (Table).
In our study, the prevalence of fibromyalgia in HS patients was lower than the overall prevalence estimates of up to 6% in the United States.5 Although fibromyalgia is associated with other autoimmune conditions, it does not appear that fibromyalgia occurs more frequently in the HS population than the general population. A limitation of this study was that we only included academic outpatient clinic visits at one institution, which may not be representative of the entire HS population. Fibromyalgia was one of the many pain disorders in this population of patients. In this population of HS patients, many had pain issues with diagnose

Practice Point
- Although fibromyalgia does not occur more frequently in hidradenitis suppurativa (HS) patients, it is important to recognize that HS patients can have comorbidities that should be addressed when possible to improve overall quality of life.
