How is oncology adapting to COVID-19?

Article Type
Changed

 

As the coronavirus pandemic escalates in the United States, Medscape Oncology reached out to a group of our contributors and asked them to provide their perspective on how their oncology departments and centers are preparing. Here are their responses to a number of issues facing oncologists in the US and around the world.
 

Have you shifted nonurgent follow-up visits to telemedicine, either via video or phone?

Kathy Miller, MD, Associate Director of Indiana University Simon Cancer Center: We are reviewing our clinic schedules and identifying “routine” follow-up patients who can be rescheduled. When patients are contacted to reschedule, they are asked if they have any urgent, immediate concerns that need to be addressed before the new appointment. If yes, they are offered a virtual visit.

Don Dizon, MD, Director of Women’s Cancers, Lifespan Cancer Institute; Director of Medical Oncology, Rhode Island Hospital: We have started to do this in preparation for a surge of people with COVID-19. Patients who are in long-term follow-up (no evidence of disease at 3 years or longer, being seen annually) or those in routine surveillance after curative treatment (that is, seen every 3 months) as well as those being seen for supportive care–type visits, like sexual health or survivorship, are all being contacted and visits are being moved to telehealth.

Jeffrey S. Weber, MD, PhD, Deputy Director of the Laura and Isaac Perlmutter Cancer Center at NYU Langone Medical Center: Yes. Any follow-up, nontreatment visits are done by phone or video if the patient agrees. (They all have).
 

Have you delayed or canceled cancer surgeries?

Ravi B. Parikh, MD, MPP, Medical oncologist at the University of Pennsylvania and the Philadelphia VA Medical Center: The University of Pennsylvania has taken this seriously. We’ve canceled all elective surgeries, have ramped up our telemedicine (video and phone) capabilities significantly, are limiting our appointments mostly to on-treatment visits, and have been asked to reconsider regular scans and reviews.

Dizon: We have not done this. There are apparently differences in interpretation in what institutions might mean as “elective surgeries.” At our institution, surgery for invasive malignancies is not elective. However, this may (or will) change if resources become an issue.

Lidia Schapira, MD, Associate Professor of Medicine and Director of Cancer Survivorship at the Stanford Comprehensive Cancer Institute: Delaying elective surgery is something that hospitals here have already implemented, and I imagine that this trend will spread. But it may be difficult to decide in situations that are not exactly “life-saving” but where an earlier intervention could preserve function or improve quality of life.

Mark A. Lewis, MD, Director of Gastrointestinal Oncology at Intermountain Healthcare in Utah: Cancer surgeries have not been deemed elective or delayed.

Have you delayed or altered the delivery of potentially immune-comprising treatments?

David Kerr, MD, Professor of Cancer Medicine at the University of Oxford in England: We are considering delaying initiation of our adjuvant colorectal cancer treatments, as we have data from our own QUASAR trials suggesting that patients who commence chemotherapy between 2 and 6 weeks do equally as well as those who begin 6-12 weeks after surgery.

Parikh: I personally haven’t delayed giving chemotherapy to avoid immune compromise, but I believe some others may have. It’s a delicate balance between wanting to ensure cancer control and making sure we are flattening the curve. As an example, though, I delayed three on-treatment visits for my clinic last Monday, and I converted 70% of my visits to telemedicine. However, I’m a genitourinary cancer specialist and the treatments I give are very different from others.

Lewis: The most difficult calculus is around adjuvant therapy. For metastatic patients, I am trying to use the least immunosuppressive regimen possible that will still control their disease. As you can imagine, it’s an assessment of competing risks.

 

 

Schapira: Patients who need essential anticancer therapy should still get it, but attempts to deintensify therapy should continue—for example, holding or postponing treatment without harm (based on evidence, not opinion). This may be possible for patients considering hormonal therapies for breast or prostate cancer.

Patients who need radiation should discuss the timing with their radiation oncologist. In some cases, it may be possible to delay treatment without affecting outcomes, but these decisions should be made carefully. Alternatively, shorter courses of radiation may be appropriate.
 

Have you advised your own patients differently given the high risk to cancer patients?

Kerr: We have factored potential infection with the virus into discussions where the benefits of chemotherapy are very marginal. This could tip the balance toward the patient deciding not to pursue chemotherapy.

Dizon: The data from China are not entirely crystal-clear. While they noted that people with active cancer and those who had a history of cancer are at increased risk for more severe infections and worse outcomes, the Chinese cohort was small, and compared with people without cancer, it tended to be much older and to be smokers (former or current). Having said this, we are counseling everyone about the importance of social distancing, washing hands, and not touching your face.

Lewis: If I have a complete blood count with a differential that includes lymphocytes, I can advise my lymphopenic patients (who are particularly vulnerable to viral infection) to take special precautions regarding social distancing in their own families.
 

Have any of your hospitalized patients been affected by policy changes to prepare beds/departments for the expected increase in COVID-19–positive patients?

Weber: Not yet.

Dizon: No, not at the moment.
 

Have you been asked to assist with other services or COVID-19 task forces?

Dizon: I am keenly involved in the preparations and modifications to procedures, including staffing decisions in outpatient, movement to telehealth, and work-from-home policies.

Lewis: I am engaged in system-wide COVID-19 efforts around oncology.

Kerr: Perhaps oddest of all, I am learning with some of our junior doctors to care for ventilated patients. I still consider myself enough of a general physician that I would hope to be able to contribute to the truly sick, but I accept that I do need an appropriate refresher course.

Bishal Gyawali, MD, PhD, medical oncologist at Queen’s University Cancer Research Institute: Queen’s Hospital medical students are now volunteering to help with daycare, groceries, and other tasks for staff who are working in the hospital.
 

Are you experiencing any shortages in personal protective equipment (PPE) at your center?

Miller: Some supplies are running short, though none are frankly out at this point. However, rationing and controls are in place to stretch the supplies as far as possible, including reusing some PPE.

Dizon: We are rationing face masks and N95 respirators, eye shields, and even surgical scrubs. We are talking about postponing elective surgery to save PPE but are not yet to that point. We’re asking that face masks be reused for at least 2 days, maybe longer. PPEs are one per day. Scrubs are kept secure.

Lewis: We are being very careful not to overuse PPE but currently have an adequate inventory. We have had to move gloves and masks to areas where they are not accessible to the general public, as otherwise they were being stolen (this started weeks ago).

Kerr: Our National Health System has an adequate supply of PPE equipment centrally, but there seems to be a problem with distribution, as some hospitals are reporting shortages.

Weber: Masks are in short supply, so they are being used for several days if not wet. We are short of plastic gowns and are using paper chemo gowns. Similar story at many places.

Disruptions in cancer care in the era of COVID-19

Article Type
Changed

Editor’s note: Find the latest COVID-19 news and guidance in Medscape’s Coronavirus Resource Center.
 

Even in the midst of the COVID-19 pandemic, cancer care must go on, but changes may need to be made in the way some care is delivered.

Dr. J. Leonard Lichtenfeld

“We’re headed for a time when there will be significant disruptions in the care of patients with cancer,” said Len Lichtenfeld, MD, deputy chief medical officer of the American Cancer Society (ACS), in a statement. “For some it may be as straightforward as a delay in having elective surgery. For others it may be delaying preventive care or adjuvant chemotherapy that’s meant to keep cancer from returning or rescheduling appointments.”

Lichtenfeld emphasized that cancer care teams are going to do the best they can to deliver care to those most in need. However, even in those circumstances, it won’t be life as usual. “It will require patience on everyone’s part as we go through this pandemic,” he said.

“The way we treat cancer over the next few months will change enormously,” writes a British oncologist in an article published in the Guardian.

“As oncologists, we will have to find a tenuous balance between undertreating people with cancer, resulting in more deaths from the disease in the medium to long term, and increasing deaths from COVID-19 in a vulnerable patient population. Alongside our patients we will have to make difficult decisions regarding treatments, with only low-quality evidence to guide us,” writes Lucy Gossage, MD, consultant oncologist at Nottingham University Hospital, UK.

The evidence to date (from reports from China in Lancet Oncology) suggests that people with cancer have a significantly higher risk of severe illness resulting in intensive care admissions or death when infected with COVID-19, particularly if they recently had chemotherapy or surgery.

“Many of the oncology treatments we currently use, especially those given after surgery to reduce risk of cancer recurrence, have relatively small benefits,” she writes.

“In the current climate, the balance of offering these treatments may shift; a small reduction in risk of cancer recurrence over the next 5 years may be outweighed by the potential for a short-term increase in risk of death from COVID-19. In the long term, more people’s cancer will return if we aren’t able to offer these treatments,” she adds.

Postpone Routine Screening

One thing that can go on the back burner for now is routine cancer screening, which can be postponed for now in order to conserve health system resources and reduce contact with healthcare facilities, says the ACS.

“Patients seeking routine cancer screenings should delay those until further notice,” said Lichtenfeld. “While timely screening is important, the need to prevent the spread of coronavirus and to reduce the strain on the medical system is more important right now.”

But as soon as restrictions to slow the spread of COVID-19 are lifted and routine visits to health facilities are safe, regular screening tests should be rescheduled.

Guidance From ASCO

The American Society of Clinical Oncology (ASCO) has issued new guidance on caring for patients with cancer during the COVID-19 outbreak.

First and foremost, ASCO encourages providers, facilities, and anyone caring for patients with cancer to follow the existing guidelines from the Center for Disease Control and Prevention when possible.

ASCO highlights the CDC’s general recommendation for healthcare facilities that suggests “elective surgeries” at inpatient facilities be rescheduled if possible, which has also been recommended by the American College of Surgeons.

However, in many cases, cancer surgery is not elective but essential, it points out. So this is largely an individual determination that clinicians and patients will need to make, taking into account the potential harms of delaying needed cancer-related surgery.

Systemic treatments, including chemotherapy and immunotherapy, leave cancer patients vulnerable to infection, but ASCO says there is no direct evidence to support changes in regimens during the pandemic. Therefore, routinely stopping anticancer or immunosuppressive therapy is not recommended, as the balance of potential harms that may result from delaying or interrupting treatment versus the potential benefits of possibly preventing or delaying COVID-19 infection remains very unclear.

Clinical decisions must be individualized, ASCO emphasized, and suggested the following practice points be considered:

  • For patients already in deep remission who are receiving maintenance therapy, stopping treatment may be an option.
  • Some patients may be able to switch from IV to oral therapies, which would decrease the frequency of clinic visits.
  • Decisions on modifying or withholding chemotherapy need to consider both the indication and goals of care, as well as where the patient is in the treatment regimen and tolerance to the therapy. As an example, the risk–benefit assessment for proceeding with chemotherapy in patients with untreated extensive small-cell lung cancer is quite different than proceeding with maintenance pemetrexed for metastatic non–small cell lung cancer.
  • If local coronavirus transmission is an issue at a particular cancer center, reasonable options may include taking a 2-week treatment break or arranging treatment at a different facility.
  • Evaluate if home infusion is medically and logistically feasible.
  • In some settings, delaying or modifying adjuvant treatment presents a higher risk of compromised disease control and long-term survival than in others, but in cases where the absolute benefit of adjuvant chemotherapy may be quite small and other options are available, the risk of COVID-19 may be considered an additional factor when evaluating care.

Delay Stem Cell Transplants

For patients who are candidates for allogeneic stem cell transplantation, a delay may be reasonable if the patient is currently well controlled with conventional treatment, ASCO comments. It also directs clinicians to follow the recommendations provided by the American Society of Transplantation and Cellular Therapy and from the European Society for Blood and Marrow Transplantation regarding this issue.

Finally, there is also the question of prophylactic antiviral therapy: Should it be considered for cancer patients undergoing active therapy?

The answer to that question is currently unknown, says ASCO, but “this is an active area of research and evidence may be available at any time.”

“As oncologists, we will have to find a tenuous balance between undertreating people with cancer, resulting in more deaths from the disease in the medium to long term, and increasing deaths from COVID-19 in a vulnerable patient population. Alongside our patients we will have to make difficult decisions regarding treatments, with only low-quality evidence to guide us,” writes Lucy Gossage, MD, consultant oncologist at Nottingham University Hospital, UK.

The evidence to date (from reports from China in Lancet Oncology) suggests that people with cancer have a significantly higher risk of severe illness resulting in intensive care admissions or death when infected with COVID-19, particularly if they recently had chemotherapy or surgery.

“Many of the oncology treatments we currently use, especially those given after surgery to reduce risk of cancer recurrence, have relatively small benefits,” she writes.

“In the current climate, the balance of offering these treatments may shift; a small reduction in risk of cancer recurrence over the next 5 years may be outweighed by the potential for a short-term increase in risk of death from COVID-19. In the long term, more people’s cancer will return if we aren’t able to offer these treatments,” she adds.

Postpone Routine Screening

One thing that can go on the back burner for now is routine cancer screening, which can be postponed for now in order to conserve health system resources and reduce contact with healthcare facilities, says the ACS.

“Patients seeking routine cancer screenings should delay those until further notice,” said Lichtenfeld. “While timely screening is important, the need to prevent the spread of coronavirus and to reduce the strain on the medical system is more important right now.”

But as soon as restrictions to slow the spread of COVID-19 are lifted and routine visits to health facilities are safe, regular screening tests should be rescheduled.

Guidance From ASCO

The American Society of Clinical Oncology (ASCO) has issued new guidance on caring for patients with cancer during the COVID-19 outbreak.

First and foremost, ASCO encourages providers, facilities, and anyone caring for patients with cancer to follow the existing guidelines from the Center for Disease Control and Prevention when possible.

ASCO highlights the CDC’s general recommendation for healthcare facilities that suggests “elective surgeries” at inpatient facilities be rescheduled if possible, which has also been recommended by the American College of Surgeons.

However, in many cases, cancer surgery is not elective but essential, it points out. So this is largely an individual determination that clinicians and patients will need to make, taking into account the potential harms of delaying needed cancer-related surgery.

Systemic treatments, including chemotherapy and immunotherapy, leave cancer patients vulnerable to infection, but ASCO says there is no direct evidence to support changes in regimens during the pandemic. Therefore, routinely stopping anticancer or immunosuppressive therapy is not recommended, as the balance of potential harms that may result from delaying or interrupting treatment versus the potential benefits of possibly preventing or delaying COVID-19 infection remains very unclear.

Clinical decisions must be individualized, ASCO emphasized, and suggested the following practice points be considered:

  • For patients already in deep remission who are receiving maintenance therapy, stopping treatment may be an option.
  • Some patients may be able to switch from IV to oral therapies, which would decrease the frequency of clinic visits.
  • Decisions on modifying or withholding chemotherapy need to consider both the indication and goals of care, as well as where the patient is in the treatment regimen and tolerance to the therapy. As an example, the risk–benefit assessment for proceeding with chemotherapy in patients with untreated extensive small-cell lung cancer is quite different than proceeding with maintenance pemetrexed for metastatic non–small cell lung cancer.
  • If local coronavirus transmission is an issue at a particular cancer center, reasonable options may include taking a 2-week treatment break or arranging treatment at a different facility.
  • Evaluate if home infusion is medically and logistically feasible.
  • In some settings, delaying or modifying adjuvant treatment presents a higher risk of compromised disease control and long-term survival than in others, but in cases where the absolute benefit of adjuvant chemotherapy may be quite small and other options are available, the risk of COVID-19 may be considered an additional factor when evaluating care.

Delay Stem Cell Transplants

For patients who are candidates for allogeneic stem cell transplantation, a delay may be reasonable if the patient is currently well controlled with conventional treatment, ASCO comments. It also directs clinicians to follow the recommendations provided by the American Society of Transplantation and Cellular Therapy and from the European Society for Blood and Marrow Transplantation regarding this issue.

Finally, there is also the question of prophylactic antiviral therapy: Should it be considered for cancer patients undergoing active therapy?

The answer to that question is currently unknown, says ASCO, but “this is an active area of research and evidence may be available at any time.”

New melanoma treatments linked to mortality decline

Article Type
Changed

 

Recent advances in treatment appear to have reversed the course of melanoma mortality since 2013, according to data published in the American Journal of Public Health.

The U.S. death rate for melanoma, which had been rising at a rate of 0.22% a year for more than 2 decades, dropped by 17.9%, or 6.24% per year, during 2013-2016. That decline “coincides with the introduction of multiple new and efficacious treatments for metastatic melanoma,” such as BRAF inhibitors and immune checkpoint inhibitors, study author Juliana Berk-Krauss, MD, of the State University of New York Downstate Medical Center in Brooklyn and colleagues wrote.

The other possible explanation for the decline in deaths, “education and early detection resulting in migration toward earlier stage melanomas with a greater chance of surgical cure,” is unlikely, according to the investigators. That’s because the small decrease in median tumor thickness that occurred during 1989-2009 “is not associated with changes in prognosis.”



The investigators’ analysis encompassed data from the Surveillance, Epidemiology, and End Results registry recorded during 1986-2016. Nine registry areas were included (Atlanta, Connecticut, Detroit, Hawaii, Iowa, New Mexico, San Francisco-Oakland, Seattle-Puget Sound, and Utah), which covered about 9.4% of the U.S. population. The analysis was limited to the white population, which accounts for more than 90% of melanoma cases in the United States.

The data showed a slight decline in annual percent change in melanoma incidence, from 3.24% for 1986-2005 to 1.72% for 2006-2016. However, over the whole period studied (1986-2016), melanoma incidence increased by 108%, or about 2.7% per year.

“Given the increased incidence of melanoma throughout this period and the lack of stage migration, these data strongly suggest that the mortality decline is due to the extended survival associated with these [newer] treatments,” the investigators wrote.

This study was funded by NYU Langone. Two investigators disclosed potential conflicts of interest, including relationships with Bio-Rad Laboratories, Novartis, Merck, and several other companies.

Teledermoscopy using smartphones fails to boost skin cancer detection

Article Type
Changed

Skin cancer detection does not improve when patients use a dermatoscope for smartphones to capture and send photos of lesions for diagnosis, according to the Australian SKIN Project trial.

“Mobile health applications are increasingly used in cancer prevention and early detection but rarely tested stringently for their value with regard to patient care,” noted trial investigators, who were led by Monika Janda, PhD, of the University of Queensland in Brisbane, Australia. The trial was published in Lancet Digital Health.

The investigators studied 234 adults at high risk for skin cancer, asking them to perform whole-body skin self-exams in their homes at baseline, 1 month, and 2 months.

Half of patients were randomized to perform standard naked-eye exams, note suspicious lesions on a body chart, and submit the chart by email. The other half were randomized to supplement their exams with mobile dermoscopy, and they were provided with a dermatoscope (FotoFinder) that interfaces with smartphones to capture and submit photos of suspicious lesions to a dermatologist for telediagnosis.

Both groups received Web-based instructions on how to complete whole-body skin self-exams and were examined in person within 3 months of their last self-exam to provide a reference standard.

In comparing the two approaches for early detection of skin cancer, the investigators determined that teledermoscopy-enhanced exams would have to show 20% greater sensitivity to establish their superiority.

The median number of lesions submitted was six per person in both the group using adjunctive teledermoscopy and the group performing only naked-eye exams.

At the lesion level, teledermoscopy-enhanced exams had lower sensitivity than naked-eye exams in detecting suspected skin cancers or precursor lesions (75% vs. 88%; P = .04) and similar specificity (87% vs. 89%; P = .42). At the patient level, the two approaches had statistically indistinguishable sensitivity (87% vs. 97%; P = .26) and specificity (95% vs. 96%; P = .96).

At the same time, telediagnosis showed good overall diagnostic concordance with in-person clinical skin examination (88%).

“For the early detection of skin cancer, naked-eye skin self-examination should continue to be recommended by cancer agencies,” Dr. Janda and colleagues concluded. “Further improvements to the instructions for participants on the relevance of nonpigmented skin lesions, training for partners, and the integration of automatic algorithms that rule out clearly benign skin lesions at the time of photographing might increase sensitivity of teledermoscopy in the future.”

This trial was funded by the National Health and Medical Research Council. The authors disclosed relationships with e-derm-consult, SciBase, Canfield Scientific, and other companies.

Patients accept artificial intelligence in skin cancer screening

Article Type
Changed

In a small survey, 75% of dermatology patients said they would recommend the use of artificial intelligence (AI) for skin cancer screening to friends and family members, but 94% emphasized the need for symbiosis between doctors, patients, and AI.

AI under investigation in dermatology includes both direct-to-patient and clinician decision-support AI tools for skin cancer screening, but patients’ perceptions of AI in health care remains unclear, Caroline A. Nelson, MD, of Yale University in New Haven, Conn., and colleagues wrote in JAMA Dermatology.

“We sought to elucidate perceived benefits and risks, strengths and weaknesses, implementation, response to conflict between human and AI clinical decision making, and recommendation for or against AI,” the researchers wrote.

They identified 48 patients seen from May 6, 2019, to July 8, 2019, at general dermatology clinics and melanoma clinics. This included 16 patients with a history of melanoma, 16 with a history of nonmelanoma skin cancer, and 16 with no history of skin cancer. The average age of the patients was 53.3 years, 54% were women, and 94% were white.

The researchers interviewed 24 patients about a direct-to-patient AI tool and 24 patients about a clinician decision-support AI tool.

Overall, 36 patients (75%) said they would recommend the AI tool to family and friends, with 17 patients (71%) saying they would recommend the direct-to-patient tool and 19 (79%) saying they would recommend the clinician decision-support tool. Another nine patients (19%) were ambivalent about the AI tools, and three patients (6%) said they would not recommend the tools.

Diagnostic speed and health care access were the most common perceived benefits of AI (by 60% of patients for each), and increased patient anxiety was the most common perceived risk (by 40% of patients). In addition, 69% of patients perceived more accurate diagnosis to be the greatest strength of an AI tool, and 85% perceived less accurate diagnosis to be the greatest weakness.

The study findings were limited by several factors, including the small sample size, qualitative design, use of a hypothetical rather than real-world situation, and a homogeneous study population, the researchers noted. However, the results merit more studies to obtain perspectives from diverse populations, they said.

“This expansion is particularly important in light of concerns raised that AI tools may exacerbate health care disparities in dermatology,” the researchers wrote.

From the patient perspective, the use of AI “may improve health care quality but should be implemented in a manner that preserves the integrity of the human physician-patient relationship,” the authors concluded.

“Although AI technology has not been widely implemented in dermatology yet, it is the pivotal time to assess patients’ views on the subject to understand their knowledge base, as well as values, preferences, and concerns regarding AI,” wrote Carrie L. Kovarik, MD, of the University of Pennsylvania in Philadelphia, in an accompanying editorial.

“Vulnerable patients, including racial and ethnic minorities, the underinsured or uninsured, economically disadvantaged, and those with chronic health conditions, may be at risk for improper consent for or use of AI,” she wrote.

Dr. Kovarik cited the position statement on augmented intelligence from the American Academy of Dermatology, which states that, for both patients and clinicians, “there should be transparency and choice on how their medical information is gathered, utilized, and stored and when, what, and how augmented intelligence technologies are utilized in their care process. There should be clarity in the symbiotic and synergistic roles of augmented intelligence and human judgment so that it is clear to the patient and provider when and how this technology is utilized to augment human judgment and interpretation.”

Clinicians will need to understand the perspectives on AI from patients of a range of backgrounds to achieve this goal, Dr. Kovarik said.

Dr. Nelson had no financial conflicts to disclose, but her colleagues disclosed relationships with pharmaceutical companies, government agencies, and nonprofit organizations. Dr. Kovarik disclosed serving on the artificial intelligence task force for the American Academy of Dermatology.

Largest meeting on cancer research canceled: AACR

Article Type
Changed

The biggest cancer research meeting of the year has been canceled as a reaction to the novel coronavirus (COVID-19) outbreak, which has also led to many other medical conferences being canceled or postponed.

The annual meeting of the American Association for Cancer Research (AACR) was due to take place April 24-29 in San Diego, California. More than 24,000 delegates from 80 countries and more than 500 exhibitors were expected to attend.

There are plans to reschedule it for later this year.

This has been a “difficult decision,” said the AACR board of directors, but “we believe that the decision to postpone the meeting is absolutely the correct one to safeguard our meeting participants from further potential exposure to the coronavirus.”

The board goes on to explain that “this evidence-based decision was made after a thorough review and discussion of all factors impacting the annual meeting, including the US government’s enforcement of restrictions on international travelers to enter the US; the imposition of travel restrictions issued by US government agencies, cancer centers, academic institutions, and pharmaceutical and biotech companies; and the counsel of infectious disease experts. It is clear that all of these elements significantly affect the ability of delegates, speakers, presenters of proffered papers, and exhibitors to participate fully in the annual meeting.”

Other cancer conferences that were planned for March and that have been canceled include the following:

  • European Breast Cancer Conference (EBCC), Barcelona, Spain, which was to have taken place March 18-20. This conference has been postponed and will now take place September 30 to October 2 at the same venue. Abstracts that have been accepted for the initial conference will remain in the program, and organizers will reopen abstract submissions in May.
  • National Comprehensive Cancer Network (NCCN), Orlando, Florida, was scheduled for March 19-22. This conference has been postponed. No new dates have been provided, but the society notes that “NCCN staff is working as quickly as possible to notify all conference registrants about the postponement and further information regarding the refund process.”
  • European Association of Urology (EAU), Amsterdam, the Netherlands, at which there is always new research presented on prostate, kidney, and bladder cancer, was due to take place March 20-24. This conference has been postponed to July 2020.
  • Society of Gynecologic Oncology (SGO), in Toronto, Canada, which was scheduled for March 28-31. SGO is “exploring alternatives for delivering the science and education.”

Overall, the move to cancel medical conferences over the next few months is a good idea, commented F. Perry Wilson, MD, MSCE, associate professor of medicine and director of Yale’s Program of Applied Translational Research, in a Medscape Medical News commentary.

“There’s a pretty straightforward case here,” he argued. “Medical professionals are at higher risk for exposure to coronavirus because we come into contact with lots and lots of patients. Gathering a large group of medical professionals in a single place increases the risk for exposure further. Factor in airplane flights to and from the conferences, and the chance that infection is spread is significant.”

Data overwhelmingly support use of dermoscopy in practice

Article Type
Changed

LAHAINA, HAWAII – Multiple studies, including meta-analyses, have shown that dermoscopy improves sensitivity for diagnosing melanoma, without lowering specificity, but there are still some “nonbelievers,” Ashfaq A. Marghoob, MD, said at the Hawaii Dermatology Seminar provided by Global Academy for Medical Education/Skin Disease Education Foundation.

In fact, not one study has shown that dermoscopy is less sensitive than the naked eye alone, and at clinics where dermoscopy is used, “two-thirds of the melanomas being detected now lack the classic ABCD features of melanoma,” added Dr. Marghoob, director of clinical dermatology at Memorial Sloan Kettering in Hauppauge, N.Y.

Dr. Marghoob cited a meta-analysis of 9 prospective trials, which concluded that dermoscopy was more accurate in diagnosing melanoma than the naked eye alone and did not lower specificity, with a sensitivity and specificity of 90%, compared with 71% and 81%, respectively for the naked eye (Br J Dermatol. 2008 Sep;159[3]:669-76).

“And at least from an evidence-based standpoint ... the Cochrane library has basically endorsed that, yes, dermoscopy does indeed improve your diagnostic accuracy,” Dr. Marghoob said.

He referred to a 2018 Cochrane review on 104 dermoscopy studies, with and without visual inspection, for diagnosing melanoma in adults (Cochrane Database Syst Rev. 2018 Dec 4;12:CD011902). The review authors concluded that “the evidence suggests that melanomas will be missed if visual inspection is used on its own,” and despite limitations in the evidence, “dermoscopy is a valuable tool to support the visual inspection of a suspicious skin lesion for the detection of melanoma and atypical intraepidermal melanocytic variants.”

As for the question of specificity, Dr. Marghoob said studies have found that dermoscopy results in the detection of more melanomas and reduces the number of biopsies of benign lesions and “every study looking into this has shown that, yes, it does improve” specificity.

A 10-year multicenter survey of about 300,000 cases, which included 17,172 melanomas and 283,043 melanocytic nevi, found that the number-needed-to-excise (NNE) values improved over time in specialized clinics where newer diagnostic techniques like dermoscopy were used (from 12.8 to 6.8), but the NNE did not appear to change in the nonspecialized settings (J Am Acad Dermatol. 2012 Jul;67[1]:54-9).

Looking at the benign-to-malignant ratio, there was no change among those not using dermoscopy, where the ratio remained at about 30 to 1. When dermoscopy was used, this ratio started to improve over the 10-year period, to about 5 to 1. In addition, “the dermoscopy users were finding many more melanomas than the non–dermoscopy users,” Dr. Marghoob added. And over the 10 years, the number of nevi being removed did not change among those not using dermoscopy but dropped among those using dermoscopy.

Adding photography with the ability to digitally monitor patients helps bring this ratio down further, Dr. Marghoob noted. He referred to a study that instead evaluated the ratio of melanoma to nonmelanomas diagnosed among dermatologists in three groups: those with no digital dermoscopy with little dermoscopy training (group A, the reference group), no digital dermoscopy but more dermoscopy training (group B), and those using digital dermoscopy (group C). In the group that used digital dermoscopy, that ratio was about 1 to 2.4, compared with about 1 to 8 in group B, and about 1 to 10.7 in group A (Br J Dermatol. 2012;167[4]778-86).

The use of dermoscopy is also associated with thinner tumors. Among dermoscopy users, the thickness of the tumors detected drops, and the proportion of thin to thick lesions detected increases, Dr. Marghoob said.

For example, in one study, the mean thickness in melanomas detected with dermoscopy was 1.4 mm versus 2.59 mm when dermoscopy was not used (J Eur Acad Dermatol Venereol. 2015 Jan; 29[1]:102-8). About 55% of the tumors detected with dermoscopic examination were 1 mm or less in thickness versus 23.4% of those detected without dermoscopy, “so the dermoscopy users from a proportion standpoint were also finding thinner tumors,” Dr. Marghoob said. Dermoscopy was also identified as an independent predictor of finding thinner tumors.

Even without a study, it could be assumed that the use of dermoscopy would reduce costs, since dermoscopy increases sensitivity and the total number of melanomas detected, decreases the number of benign nevi removed, and helps detect disease earlier. But there are data showing that dermoscopy reduces health care costs, Dr. Marghoob said.* For example, a Belgian study that looked at dermoscopy in two cohorts of melanoma patients concluded that adequate dermoscopy training was cost effective (Eur J Cancer. 2016 Nov;67:38-45).

It has also been shown that adding dermoscopy to a primary care setting has cost benefits, Dr. Marghoob said. He cited a study of Dutch general practices that found that the probability of a correct diagnosis was 1.25 times higher when dermoscopy was used to evaluate suspicious skin lesions and concluded that the use of dermoscopy appeared to be cost effective (J Eur Acad Dermatol Venereol. 2014 Nov;28[11]:1442-9).

Dr. Marghoob had no disclosures relevant to this presentation.

Tumor neoantigenicity metric improves prediction of response to immunotherapy

Article Type
Changed

A new tumor neoantigenicity metric may improve prediction of response to immunotherapy in patients with melanoma, lung cancer, and kidney cancer, a retrospective analysis suggests.

The new metric, known as the Cauchy-Schwarz index of neoantigens (CSiN) score, incorporates both immunogenicity and clonality, according to lead study author Tianshi Lu, a PhD candidate at the University of Texas Southwestern Medical Center in Dallas, and colleagues.

“The major biological insight from this study is that the neoantigen clonal structure in each tumor specimen and the immunogenicity of the neoantigens (represented by the MHC-binding strength in our study) are predictive of response to checkpoint inhibitors and prognosis,” the investigators wrote in Science Immunology.

The study involved 2,479 patients with various cancers, including immunogenic types such as renal cell carcinoma (RCC), and nonimmunogenic types, such as pediatric acute lymphocytic leukemia.

The investigators first evaluated CSiN in relation to clinical outcome among patients with immunogenic cancers who received immunotherapy. Drawing data from multiple cohorts, the investigators found that patients who had better responses to therapy were significantly more likely to have above average CSiN scores than those who had worse responses.

In one cohort of patients with melanoma who received anti–CTLA-4 therapy, those with better responses were more likely to have high CSiN scores (P = .009). In another cohort of melanoma patients who received anti–CTLA-4 therapy, those with higher CSiN scores were more likely to achieve durable clinical benefit (response or stable disease for more than 6 months), compared with patients who had lower CSiN scores (P = .033).

Among patients with clear cell RCC treated with anti-PD-1/PD-L1 therapy, there was a significant positive association between higher CSiN scores and better response (P = .036). Among T effector-high patients with metastatic clear cell RCC, there was a significant association between higher CSiN scores and better response to atezolizumab (P = .028) but not sunitinib (P = .890).

 

 


In a cohort of patients with non–small cell lung cancer treated with checkpoint inhibitors, those with sustained responses were more likely to have higher CSiN scores than were patients with short-term progression (P = .015).

The investigators also compared the predictive power of CSiN with existing neoantigenicity metrics, ultimately concluding that CSiN was superior.

“Overall, the neoantigen load and neoantigen fitness models were not as strongly predictive of treatment response as CSiN,” the investigators wrote.

Again using data from patients with immunogenic cancers, the investigators looked for an association between CSiN score and overall survival. Indeed, patients with higher-than-average CSiN scores had significantly better survival than that of those with lower scores (P less than .001). This finding was maintained in a multivariate analysis that accounted for disease type, stage, sex, and age.

In contrast with the above findings, CSiN did not predict survival among patients with nonimmunogenic cancer types.

“Overall, our work offers a rigorous methodology of predicting response to immunotherapy and prognosis from routine patient samples and should be useful for personalizing medicine in the modern era of immunotherapy,” the investigators concluded.

The study was funded by the National Institutes of Health, the Cancer Prevention Research Institute of Texas, and the American Cancer Society. The investigators reported no conflicts of interest.

The study was funded by the National Institutes of Health, the Cancer Prevention Research Institute of Texas, and the American Cancer Society. The investigators reported no conflicts of interest.

A new tumor neoantigenicity metric may improve prediction of response to immunotherapy in patients with melanoma, lung cancer, and kidney cancer, a retrospective analysis suggests.

The new metric, known as the Cauchy-Schwarz index of neoantigens (CSiN) score, incorporates both immunogenicity and clonality, according to lead study author Tianshi Lu, a PhD candidate at the University of Texas Southwestern Medical Center in Dallas, and colleagues.

“The major biological insight from this study is that the neoantigen clonal structure in each tumor specimen and the immunogenicity of the neoantigens (represented by the MHC-binding strength in our study) are predictive of response to checkpoint inhibitors and prognosis,” the investigators wrote in Science Immunology.

The study involved 2,479 patients with various cancers, including immunogenic types such as renal cell carcinoma (RCC), and nonimmunogenic types, such as pediatric acute lymphocytic leukemia.

The investigators first evaluated CSiN in relation to clinical outcome among patients with immunogenic cancers who received immunotherapy. Drawing data from multiple cohorts, the investigators found that patients who had better responses to therapy were significantly more likely to have above average CSiN scores than those who had worse responses.

In one cohort of patients with melanoma who received anti–CTLA-4 therapy, those with better responses were more likely to have high CSiN scores (P = .009). In another cohort of melanoma patients who received anti–CTLA-4 therapy, those with higher CSiN scores were more likely to achieve durable clinical benefit (response or stable disease for more than 6 months), compared with patients who had lower CSiN scores (P = .033).

Among patients with clear cell RCC treated with anti-PD-1/PD-L1 therapy, there was a significant positive association between higher CSiN scores and better response (P = .036). Among T effector-high patients with metastatic clear cell RCC, there was a significant association between higher CSiN scores and better response to atezolizumab (P = .028) but not sunitinib (P = .890).

 

 


In a cohort of patients with non–small cell lung cancer treated with checkpoint inhibitors, those with sustained responses were more likely to have higher CSiN scores than were patients with short-term progression (P = .015).

The investigators also compared the predictive power of CSiN with existing neoantigenicity metrics, ultimately concluding that CSiN was superior.

“Overall, the neoantigen load and neoantigen fitness models were not as strongly predictive of treatment response as CSiN,” the investigators wrote.

Again using data from patients with immunogenic cancers, the investigators looked for an association between CSiN score and overall survival. Indeed, patients with higher-than-average CSiN scores had significantly better survival than that of those with lower scores (P less than .001). This finding was maintained in a multivariate analysis that accounted for disease type, stage, sex, and age.

In contrast with the above findings, CSiN did not predict survival among patients with nonimmunogenic cancer types.

“Overall, our work offers a rigorous methodology of predicting response to immunotherapy and prognosis from routine patient samples and should be useful for personalizing medicine in the modern era of immunotherapy,” the investigators concluded.

The study was funded by the National Institutes of Health, the Cancer Prevention Research Institute of Texas, and the American Cancer Society. The investigators reported no conflicts of interest.

Banning indoor tanning devices could save lives and money

Article Type
Changed

Banning indoor tanning devices outright in the United States, Canada, and Europe could prevent as many as 448,000 melanomas and 9.7 million keratinocyte carcinomas, according to a study published in JAMA Dermatology.

The study also suggests a ban would result in a collective cost savings of $5.7 billion and productivity gains of $41.3 billion.

Compared with a ban on indoor tanning for minors, the benefits of a full ban on devices were 3.7-fold higher in the United States/Canada and 2.6-fold higher in Europe, according to study author Louisa G. Gordon, PhD, of the QIMR Berghofer Medical Research Institute in Brisbane, Australia, and colleagues.

The researchers noted that indoor tanning is regulated in more than 20 countries. Australia has instituted a ban on commercial indoor tanning devices, and Brazil has banned both commercial and private tanning devices.

In the United States, 19 states have banned the use of indoor tanning beds for minors, and 44 states as well as the District of Columbia have some regulation of tanning facilities for minors, according to the National Conference of State Legislatures.

With this study, Dr. Gordon and colleagues sought to explore what effect an outright ban on indoor tanning devices, a prohibition for minors only, or continuing current levels of indoor tanning would have on the health and economy of the United States, Canada, and Europe.

The researchers created a Markov cohort model of 110,932,523 individuals in the United States/Canada and 141,970,492 individuals in Europe, all aged 12-35 years.

The team used data from epidemiologic studies, cost reports, and official cancer registries to estimate the prevalence of indoor tanning, risk of developing melanoma, and mortality rates from skin cancer and other causes. The researchers also estimated health care costs of melanoma treatment in each region as well as the societal cost of dying prematurely from melanoma, adjusted to 2018 dollars.
 

Results

The model suggested a ban on indoor tanning in the United States and Canada would result in 244,347 fewer melanomas (–8.7%), 89,193 fewer deaths from melanoma (–6.9%), and 7.3 million fewer keratinocyte carcinomas (–7.8%) than continuing at the current levels of use. The ban would also save 428,781 life-years, have a cost savings of $3.5 billion, and confer productivity gains of $27.5 billion, the researchers said.

When applying the ban in Europe, the model estimated 203,736 fewer melanomas (­–4.9%), 98,288 fewer deaths from melanoma (–4.4%), and 2.4 million fewer keratinocyte carcinomas (­–4.4%). The researchers also noted that Europe would see a gain of 459,669 life-years, a cost savings of $2.1 billion, and a productivity gain of $13.7 billion.

Dr. Gordon and colleagues acknowledged that their model had some limitations, such as in estimating the prevalence of certain skin cancers across Europe, which can range from 10% to 56% depending on the country. In addition, the model did not account for the money spent in implementing a ban, which could include costs associated with regulation, compliance, and buy-back schemes for tanning devices.
 

Implications

In an interview, Dr. Gordon said the researchers conducted this study to stress the health benefits and cost savings of regulating indoor tanning devices in North America and Europe. She noted that she had previously published a report in 2009 that helped Australia make the decision to ban such devices there, but she said the tanning industry was in its infancy during that time, which factored into the decision to ban indoor tanning (Health Policy. 2009 Mar;89[3]:303-11).

Any ban by a regulatory agency “should include everyone,” Dr. Gordon said, because “banning minors is a halfway attempt to prevent skin cancers.” The danger isn’t just present in children. “People in their 20s and 30s are still very image conscious,” she said. “The pressure is enormous.”

Anyone interested in tanning should use tanning creams or sprays instead of using indoor tanning devices, Dr. Gordon said. “Consumers can control their UV exposure,” she noted. “Prevention is incredibly important, and skin cancer is one of a few cancers we can almost entirely prevent via protecting our skin. The same can’t be said for other horrible cancers.”

Adam Friedman, MD, a professor at George Washington University, Washington, who was not involved in this study, said it should come as no surprise to dermatologists that preventing artificial UVA heavy exposure reduces the incidence of skin cancer, but the “more compelling component of this study is cost.”

“The lay public is extremely health care cost conscientious,” he said. “This is a commonly debated topic for emerging politicians at every level; not to mention, no one enjoys bleeding money. Dermatologists can use the angle of, ‘save skin now, save money later,’ to target the financial burden of accelerated skin aging and skin cancer as a mechanism for persuading patients not to ‘shake and bake.’ ”

While the Food and Drug Administration has proposed restricting the use of indoor tanning devices for minors nationwide, it has not issued a final rule on the matter, and the prospect of an outright ban in the United States for the general population is less feasible, noted Dr. Friedman.

“I think it would be difficult to expand this [proposed] ban given the financial impact on numerous businesses,” he said. “It would likely take more evidence and support beyond the medical community to make this happen, but here’s hoping,”

This study was funded by the World Health Organization UV Radiation Programme and Cancer Council Victoria. One author disclosed personal fees from Cancer Council Victoria, and one disclosed grants from TrygFonden. The other authors and Dr. Friedman reported no relevant conflicts of interest.

Smartphone apps for suspicious skin lesions unreliable

Article Type
Changed

Smartphone applications (apps) using so-called artificial intelligence (AI) aimed at the general public for use on suspicious skin lesions are unreliable, said U.K. researchers reporting a systematic review.
 

These apps are providing information that could lead to “potentially life-or-death decisions,” commented co-lead author Hywel C. Williams, MD, from the Centre of Evidence Based Dermatology, University of Nottingham (England).

“The one thing you mustn’t do in a situation where early diagnosis can make a difference between life and death is you mustn’t miss the melanoma,” he said in an interview.

“These apps were missing melanomas, and that’s very worrisome,” he commented.

The review included nine studies of skin cancer smartphone apps, including two apps, SkinScan and SkinVision, that have been given Conformit Europenne (CE) marks, allowing them to be marketed across Europe. These apps are also available in Australia and New Zealand, but not in the United States.

The review found that SkinScan was not able to identify any melanomas in the one study that assessed this app, while SkinVision had a relatively low sensitivity and specificity, with 12% of cancerous or precancerous lesions missed and 21% of benign lesions wrongly identified as cancerous.

This means that among 1,000 people with a melanoma prevalence of 3%, 4 of 30 melanomas would be missed, and 200 people would be incorrectly told that a mole was of high concern, the authors estimated.

The research was published by The BMJ on Feb. 10.

“Although I was broad minded on the potential benefit of apps for diagnosing skin cancer, I am now worried given the results of our study and the overall poor quality of studies used to test these apps,” Dr. Williams commented in a statement.

Coauthor Jac Dinnes, PhD, from the Institute of Applied Health Research at the University of Birmingham (England), added it is “really disappointing that there is not better quality evidence available to judge the efficacy of these apps.”

“It is vital that health care professionals are aware of the current limitations both in the technologies and in their evaluations,” she added.

The results also highlight the limitations of the regulatory system governing smartphone apps in that they are currently not subject to assessment by bodies such as the U.K.’s Medicines and Healthcare Products Regulatory Agency (MHRA), the authors commented.

“Regulators need to become alert to the potential harm that poorly performing algorithm-based diagnostic or risk monitoring apps create,” said co-lead author Jonathan J. Deeks, PhD, also at the Institute of Applied Health Research.

“We rely on the CE mark as a sign of quality, but the current CE mark assessment processes are not fit for protecting the public against the risks that these apps present.”

Speaking in an interview, Williams lamented the poor quality of the research that had been conducted. “These studies were not good enough,” he said, adding that “there’s no excuse for really poor study design and poor reporting.”

He would like to see the regulations tightened around AI apps purporting to inform decision making for the general public and suggests that these devices should be assessed by the MHRA. “I really do think a CE mark is not enough,” he said.

The team noted that the skin cancer apps “all include disclaimers that the results should only be used as a guide and cannot replace health care advice,” through which the manufacturers “attempt to evade any responsibility for negative outcomes experienced by users.”

Nevertheless, the “poor and variable performance” of the apps revealed by their review indicates that they “have not yet shown sufficient promise to recommend their use,” they concluded.

The “official approval” implied by a CE mark “will give consumers the impression that the apps have been assessed as effective and safe,” wrote Ben Goldacre, DataLab director, Nuffield Department of Primary Care, University of Oxford (England), and colleagues in an accompanying editorial.

“The implicit assumption is that apps are similarly low-risk technology” to devices such as sticking plasters and reading glasses, they comment.

“But shortcomings in diagnostic apps can have serious implications,” they warn. The “risks include psychological harm from health anxiety or ‘cyberchondria,’ and physical harm from misdiagnosis or overdiagnosis; for clinicians there is a risk of increased workload, and changes to ethical or legal responsibilities around triage, referral, diagnosis, and treatment.” There is also potential for “inappropriate resource use, and even loss of credibility for digital technology in general.”

 

 

Details of the review

For their review, the authors searched the Cochrane Central Register on Controlled Trials, the MEDLNE, Embase, Cumulative Index to Nursing and Allied Health Literature, Conference Proceedings Citation index, Zetoc, and Science Citation Index databases, and online trial registers for studies published between August 2016 and April 2019.

From 80 studies identified, 9 met the eligibility criteria.

Of those, six studies, evaluating a total of 725 skin lesions, determined the accuracy of smartphone apps in risk stratifying suspicious skin lesions by comparing them against a histopathological reference standard diagnosis or expert follow-up.

Five of these studies aimed to detect only melanoma, while one sought to differentiate between malignant or premalignant lesions (including melanoma, basal cell carcinoma, and squamous cell carcinoma) and benign lesions.

The three remaining studies, which evaluated 407 lesions in all, compared smartphone app recommendations against a reference standard of expert recommendations for further investigation or intervention.

The researchers found the studies had a string of potential biases and limitations.

For example, only four studies recruited a consecutive sample of study participants and lesions, and only two included lesions selected by study participants, whereas five studies used lesions that had been selected by a clinician.

Three studies reported that it took 5-10 attempts to obtain an adequate image. In seven studies, it was the researchers and not the patients who used the app to photograph the lesions, and two studies used images obtained from dermatology databases.

This “raised concerns that the results of the studies were unlikely to be representative of real life use,” the authors comment.

In addition, the exclusion of unevaluable images “might have systematically inflated the diagnostic performance of the tested apps,” they add.

The independent research was supported by the National Institute for Health Research (NIHR) Birmingham Biomedical Research Centre at the University Hospitals Birmingham NHS Foundation Trust and the University of Birmingham and is an update of one of a collection of reviews funded by the NIHR through its Cochrane Systematic Review Programme Grant.

Smartphone applications (apps) using so-called artificial intelligence (AI) aimed at the general public for use on suspicious skin lesions are unreliable, said U.K. researchers reporting a systematic review.
 

These apps are providing information that could lead to “potentially life-or-death decisions,” commented co-lead author Hywel C. Williams, MD, from the Centre of Evidence Based Dermatology, University of Nottingham (England).

“The one thing you mustn’t do in a situation where early diagnosis can make a difference between life and death is you mustn’t miss the melanoma,” he said in an interview.

“These apps were missing melanomas, and that’s very worrisome,” he commented.

The review included nine studies of skin cancer smartphone apps, including two apps, SkinScan and SkinVision, that have been given Conformit Europenne (CE) marks, allowing them to be marketed across Europe. These apps are also available in Australia and New Zealand, but not in the United States.

The review found that SkinScan was not able to identify any melanomas in the one study that assessed this app, while SkinVision had a relatively low sensitivity and specificity, with 12% of cancerous or precancerous lesions missed and 21% of benign lesions wrongly identified as cancerous.

This means that among 1,000 people with a melanoma prevalence of 3%, 4 of 30 melanomas would be missed, and 200 people would be incorrectly told that a mole was of high concern, the authors estimated.

The research was published by The BMJ on Feb. 10.

“Although I was broad minded on the potential benefit of apps for diagnosing skin cancer, I am now worried given the results of our study and the overall poor quality of studies used to test these apps,” Dr. Williams commented in a statement.

Coauthor Jac Dinnes, PhD, from the Institute of Applied Health Research at the University of Birmingham (England), added it is “really disappointing that there is not better quality evidence available to judge the efficacy of these apps.”

“It is vital that health care professionals are aware of the current limitations both in the technologies and in their evaluations,” she added.

The results also highlight the limitations of the regulatory system governing smartphone apps in that they are currently not subject to assessment by bodies such as the U.K.’s Medicines and Healthcare Products Regulatory Agency (MHRA), the authors commented.

“Regulators need to become alert to the potential harm that poorly performing algorithm-based diagnostic or risk monitoring apps create,” said co-lead author Jonathan J. Deeks, PhD, also at the Institute of Applied Health Research.

“We rely on the CE mark as a sign of quality, but the current CE mark assessment processes are not fit for protecting the public against the risks that these apps present.”

Speaking in an interview, Williams lamented the poor quality of the research that had been conducted. “These studies were not good enough,” he said, adding that “there’s no excuse for really poor study design and poor reporting.”

He would like to see the regulations tightened around AI apps purporting to inform decision making for the general public and suggests that these devices should be assessed by the MHRA. “I really do think a CE mark is not enough,” he said.

The team noted that the skin cancer apps “all include disclaimers that the results should only be used as a guide and cannot replace health care advice,” through which the manufacturers “attempt to evade any responsibility for negative outcomes experienced by users.”

Nevertheless, the “poor and variable performance” of the apps revealed by their review indicates that they “have not yet shown sufficient promise to recommend their use,” they concluded.

The “official approval” implied by a CE mark “will give consumers the impression that the apps have been assessed as effective and safe,” wrote Ben Goldacre, DataLab director, Nuffield Department of Primary Care, University of Oxford (England), and colleagues in an accompanying editorial.

“The implicit assumption is that apps are similarly low-risk technology” to devices such as sticking plasters and reading glasses, they comment.

“But shortcomings in diagnostic apps can have serious implications,” they warn. The “risks include psychological harm from health anxiety or ‘cyberchondria,’ and physical harm from misdiagnosis or overdiagnosis; for clinicians there is a risk of increased workload, and changes to ethical or legal responsibilities around triage, referral, diagnosis, and treatment.” There is also potential for “inappropriate resource use, and even loss of credibility for digital technology in general.”

 

 

Details of the review

For their review, the authors searched the Cochrane Central Register on Controlled Trials, the MEDLNE, Embase, Cumulative Index to Nursing and Allied Health Literature, Conference Proceedings Citation index, Zetoc, and Science Citation Index databases, and online trial registers for studies published between August 2016 and April 2019.

From 80 studies identified, 9 met the eligibility criteria.

Of those, six studies, evaluating a total of 725 skin lesions, determined the accuracy of smartphone apps in risk stratifying suspicious skin lesions by comparing them against a histopathological reference standard diagnosis or expert follow-up.

Five of these studies aimed to detect only melanoma, while one sought to differentiate between malignant or premalignant lesions (including melanoma, basal cell carcinoma, and squamous cell carcinoma) and benign lesions.

The three remaining studies, which evaluated 407 lesions in all, compared smartphone app recommendations against a reference standard of expert recommendations for further investigation or intervention.

The researchers found the studies had a string of potential biases and limitations.

For example, only four studies recruited a consecutive sample of study participants and lesions, and only two included lesions selected by study participants, whereas five studies used lesions that had been selected by a clinician.

Three studies reported that it took 5-10 attempts to obtain an adequate image. In seven studies, it was the researchers and not the patients who used the app to photograph the lesions, and two studies used images obtained from dermatology databases.

This “raised concerns that the results of the studies were unlikely to be representative of real life use,” the authors comment.

In addition, the exclusion of unevaluable images “might have systematically inflated the diagnostic performance of the tested apps,” they add.
