FDA issues proposed order for over-the-counter sunscreens

Federal efforts to improve the quality, safety, and efficacy of over-the-counter sunscreens took a step forward today with the release of two orders aimed at updating regulatory requirements for most sunscreen products in the United States.

Dr. Theresa Michele

“We see it as a key public health priority and our regulatory obligation to make sure that marketed sunscreen products offer protection from the sun’s effects and that they deliver on those promises to consumers,” Theresa Michele, MD, director of the office of nonprescription drugs in the FDA’s Center for Drug Evaluation and Research, said during a media briefing.

When the Coronavirus Aid, Relief, and Economic Security (CARES) Act was passed in 2020, the FDA was in the middle of amending a sunscreen monograph through the previous rule-making process, and the agency had issued a proposed rule for sunscreens in February of 2019. The CARES Act provided the FDA with new authority related to OTC drugs including sunscreens.

It also established a deemed final order for sunscreens, which set the current requirements for OTC sunscreen products marketed without an application. The deemed final order, released on Sept. 24, “essentially preserves the pre-CARES Act status quo marketing conditions for these sunscreens,” Dr. Michele explained. “Before the CARES Act was passed, sunscreens were marketed according to nearly identical terms that were described in an FDA enforcement discretion policy. For this reason, the agency believes that most sunscreens on the market today are already in compliance with this order.”

The CARES Act also required the FDA to issue a proposed order by Sept. 27 to amend and revise the deemed final order. Dr. Michele described the proposed order, which was released on Sept. 24, as “a vehicle to effectively transition our ongoing consideration of the appropriate requirements for OTC sunscreens marketed without approved applications from the previous rule-making process to this new order process. The provisions in today’s proposed order are therefore substantively the same as those described in the FDA’s 2019 proposed rule on sunscreens. With this proposed order, we’re proposing new requirements to improve the quality, safety, and efficacy of sunscreens that Americans use every day.”



The order proposes to update the generally recognized as safe (GRASE) status for the 16 active ingredients listed in the deemed final order. It also proposes that dosage forms that are GRASE for use as sunscreens include oils, lotions, creams, gels, butters, pastes, ointments, and sticks, and proposes GRASE status for spray sunscreens, subject to testing and labeling requirements.

Adam Friedman, MD, FAAD, professor and chair of dermatology at George Washington University, Washington, emphasized that photoprotection “is important for everyone, regardless of skin tone,” in an interview. “Broad-spectrum sunscreens with an SPF of 15 and higher play an important role in this. This should not be lost amidst the proposed order.”

Changes between the deemed and proposed order that he highlighted include a maximum SPF of 60+ (though up to 80 might be allowed) and that zinc oxide and titanium dioxide are GRASE. “The FDA did not say that nanoparticle formulations of these, which are easier to use, are not GRASE; they are asking for community input,” he said.

Other changes between the deemed and proposed order are that PABA and trolamine salicylate are not GRASE and that broad-spectrum testing will be mandatory. In addition, Dr. Friedman said, “sprays will be considered for GRASE so long as properly tested, labeling should be clearer (and a warning will be applied to those sunscreens not shown to prevent all the bad stuff with UVR [ultraviolet radiation]), and bug spray–sunscreen combos are a no-go.”

The FDA will consider comments on the proposed order submitted during a 45-day public comment period before issuing a revised final order. “As part of this process, we’ll consider all timely comments submitted both in response to the February 2019 proposed rule and to the current proposed order,” Dr. Michele said.

Dr. Friedman reported that he serves as a consultant and/or advisor to numerous pharmaceutical companies. He is also a speaker for Regeneron, Sanofi Genzyme, Abbvie, LRP, Janssen, Incyte, and Brickell Biotech, and has received grants from Pfizer, the Dermatology Foundation, Almirall, Incyte, Galderma, and Janssen.

Watchful waiting in BCC: Which patients can benefit?

Article Type
Changed
Tue, 10/05/2021 - 10:38

Basal cell carcinomas (BCCs), the most common form of skin cancer, are generally slow-growing tumors that occur in older patients.

Given the low rates of metastasis and mortality associated with BCC, some patients do not require treatment. However, there have been no evidence-based recommendations on who may benefit from a watch-and-wait approach.

Now, a study published on Sept. 8 in JAMA Dermatology sheds light on which patients with BCC may be appropriate candidates for watchful waiting.

The investigators found that, for older people with low-grade BCCs and limited life expectancy, the risks associated with surgery – bleeding, infection, and wound dehiscence – appeared to outweigh the advantages. According to the authors, these patients “might not live long enough to benefit from treatment.”

This finding mirrors oncologists’ observations regarding low-risk prostate cancer, for which watchful waiting is now the standard of care.

“At present, however, procedure rates [for patients with BCC] increase with age, and many basal cell carcinomas are treated surgically regardless of a patient’s life expectancy,” Eleni Linos, MD, PhD, professor of dermatology at Stanford (Calif.) University, and Mary-Margaret Chren, MD, chair of dermatology at Vanderbilt University, Nashville, Tenn., write in a viewpoint article published in August in JAMA Internal Medicine.

Considering the current treatment patterns for BCC, patients would “benefit from the existence of an evidence-based standard of care that includes active surveillance,” Mackenzie Wehner, MD, assistant professor at MD Anderson Cancer Center, Houston, Tex., writes in an editorial that accompanies the article in JAMA Dermatology.
 

Insights from the Dutch study

The article in JAMA Dermatology presents a cohort study conducted at Radboud University Medical Center in Nijmegen, the Netherlands. The study included 89 patients who were managed with watchful waiting. The patients received no treatment for at least 3 months following their diagnoses.

The median age of the patients was 83 years. The patients had a total of 280 BCCs. The median initial diameter of the BCCs was 9.5 mm. Just over half of the patients were men, and about half of the BCCs were in the head and neck region.

The median follow-up was 9 months; the maximum follow-up was 6.5 years. Remarkably, the investigators say, more than half the tumors (53.2%) did not grow, and some even shrank. The majority of patients were asymptomatic at presentation, and fewer than 10% developed new symptoms, such as bleeding and itching, during follow-up.

Among the tumors that did grow, 70% were low-risk superficial/nodular tumors, which only increased in size by an estimated 1.06 mm over a year. Thirty percent were higher-risk micronodular/infiltrative tumors, which grew an estimated 4.46 mm over a 12-month period.

About two-thirds of patients eventually chose to have at least one of their BCCs removed after a median of about 7 months. Only three BCCs (2.8%) needed more extensive surgery – reconstructive surgery, rather than primary closure, for instance – than would have been necessary with an earlier excision.

No deaths from BCC were reported in the study.

The investigators tracked the reasons patients opted for watchful waiting. Many understood that their tumors likely would not cause problems in their remaining years. Others prioritized dealing with more pressing health or family problems. Logistics came into play for some, such as not having reliable transportation for hospital visits.

“In patients with [limited life expectancy] and asymptomatic low-risk tumors, [watchful waiting] should be discussed as a potentially appropriate approach,” the investigators, led by Marieke E. C. van Winden, MD, a dermatology resident at Radboud University, conclude.

For patients who wish to pursue a watchful waiting approach, the Dutch team recommends conducting follow-up visits every 3-6 months to see whether patients wish to continue with watchful waiting and to determine whether the risk-to-benefit ratio has shifted.

These recommendations are in line with criteria Dr. Linos and Dr. Chren propose in their viewpoint article in JAMA Internal Medicine. They characterize low-risk BCCs as asymptomatic, smaller than 1 cm in diameter, and located on the trunk or extremities in immunocompetent patients. They note that details regarding active surveillance for BCCs need to be worked out.

“Active surveillance should be studied as a management option because it is supported by the available evidence, congruent with the care of other low-risk cancers, and in accord with principles of shared decision-making,” Dr. Linos and Dr. Chren write.

No funding source was reported. Dr. Wehner, Dr. van Winden, Dr. Linos, and Dr. Chren have disclosed no relevant financial relationships. Two of Dr. van Winden’s coauthors report ties to several companies, including Sanofi Genzyme, AbbVie, Novartis, and Janssen.

Most community-based oncologists skip biomarker testing

Article Type
Changed
Wed, 01/04/2023 - 16:58

A recent survey shows that fewer than half of community oncologists use biomarker testing to guide patient discussions about treatment, which compares with 73% of academic clinicians.

The findings, reported at the 2020 World Conference on Lung Cancer, which was rescheduled for January 2021, highlight the potential for unequal application of the latest advances in cancer genomics and targeted therapies throughout the health care system, which could worsen existing disparities in underserved populations, according to Leigh Boehmer, PharmD, medical director for the Association of Community Cancer Centers, Rockville, Md.

The survey – a mixed-methods approach for assessing practice patterns, attitudes, barriers, and resource needs related to biomarker testing among clinicians – was developed by the ACCC in partnership with the LUNGevity Foundation and administered to clinicians caring for patients with non–small cell lung cancer who are uninsured or covered by Medicaid.

Of 99 respondents, more than 85% were physicians and 68% worked in a community setting. Only 40% indicated they were very familiar or extremely familiar with 2018 Molecular Testing Guidelines for Lung Cancer from the College of American Pathologists, the International Association for the Study of Lung Cancer, and the Association for Molecular Pathology.

Clinicians were most confident about selecting appropriate tests to use, interpreting test results, and prognosticating based on test results, with 77%, 74%, and 74%, respectively, saying they are very confident or extremely confident in those areas. They were less confident about determining when to order testing and in coordinating care across the multidisciplinary team, with 59% and 64%, respectively, saying they were very confident or extremely confident in those areas, Dr. Boehmer reported at the conference.

The shortcomings with respect to communication across teams were echoed in two focus groups convened to further validate the survey results, he noted.

As for the reasons why clinicians ordered biomarker testing, 88% and 82% of community and academic clinicians, respectively, said they did so to help make targeted treatment decisions.

“Only 48% of community clinicians indicated that they use biomarker testing to guide patient discussions, compared to 73% of academic clinicians,” he said. “That finding was considered statistically significant.”

With respect to decision-making about biomarker testing, 41% said they prefer to share the responsibility with patients, whereas 52% said they prefer to make the final decision.

“Shedding further light on this situation, focus group participants expressed that patients lacked comprehension and interest about what testing entails and what testing means for their treatment options,” Dr. Boehmer noted.

In order to make more informed decisions about biomarker testing, respondents said they need more information on financial resources for patient assistance (26%) and education around both published guidelines and practical implications of the clinical data (21%).

When asked about patients’ information needs, 23% said their patients need psychosocial support, 22% said they need financial assistance, and 9% said their patients have no additional resource needs.

However, only 27% said they provide patients with resources related to psychosocial support services, and only 44% share financial assistance information, he said.

Further, the fact that 9% said their patients need no additional resources represents “a disconnect” from the findings of the survey and focus groups, he added.

“We believe that this study identifies key areas of ongoing clinician need related to biomarker testing, including things like increased guideline familiarity, practical applications of guideline-concordant testing, and … how to optimally coordinate multidisciplinary care delivery,” Dr. Boehmer said. “Professional organizations … in partnership with patient advocacy organizations or groups should focus on developing those patient education materials … and tools for improving patient-clinician discussions about biomarker testing.”

The ACCC will be working with the LUNGevity Foundation and the Center for Business Models in Healthcare to develop an intervention to ensure that such discussions are “easily integrated into the care process for every patient,” he noted.

Such efforts are important for ensuring that clinicians are informed about the value of biomarker testing and about guidelines for testing so that patients receive the best possible care, said invited discussant Joshua Sabari, MD, of New York University Langone Health’s Perlmutter Cancer Center.

“I know that, in clinic, when meeting a new patient with non–small cell lung cancer, it’s critical to understand the driver alteration, not only for prognosis, but also for goals-of-care discussion, as well as potential treatment option,” Dr. Sabari said.

Dr. Boehmer reported consulting for Pfizer. Dr. Sabari reported consulting and advisory board membership for multiple pharmaceutical companies.

“Only 48% of community clinicians indicated that they use biomarker testing to guide patient discussions, compared to 73% of academic clinicians,” he said. “That finding was considered statistically significant.”

With respect to decision-making about biomarker testing, 41% said they prefer to share the responsibility with patients, whereas 52% said they prefer to make the final decision.

“Shedding further light on this situation, focus group participants expressed that patients lacked comprehension and interest about what testing entails and what testing means for their treatment options,” Dr. Boehmer noted.

In order to make more informed decisions about biomarker testing, respondents said they need more information on financial resources for patient assistance (26%) and education around both published guidelines and practical implications of the clinical data (21%).

When asked about patients’ information needs, 23% said their patients need psychosocial support, 22% said they need financial assistance, and 9% said their patients have no additional resource needs.

However, only 27% said they provide patients with resources related to psychosocial support services, and only 44% share financial assistance information, he said.

Further, the fact that 9% said their patients need no additional resources represents “a disconnect” from the findings of the survey and focus groups, he added.

“We believe that this study identifies key areas of ongoing clinician need related to biomarker testing, including things like increased guideline familiarity, practical applications of guideline-concordant testing, and … how to optimally coordinate multidisciplinary care delivery,” Dr. Boehmer said. “Professional organizations … in partnership with patient advocacy organizations or groups should focus on developing those patient education materials … and tools for improving patient-clinician discussions about biomarker testing.”

The ACCC will be working with the LUNGevity Foundation and the Center for Business Models in Healthcare to develop an intervention to ensure that such discussions are “easily integrated into the care process for every patient,” he noted.

Such efforts are important for ensuring that clinicians are informed about the value of biomarker testing and about guidelines for testing so that patients receive the best possible care, said invited discussant Joshua Sabari, MD, of New York University Langone Health’s Perlmutter Cancer Center.

“I know that, in clinic, when meeting a new patient with non–small cell lung cancer, it’s critical to understand the driver alteration, not only for prognosis, but also for goals-of-care discussion, as well as potential treatment option,” Dr. Sabari said.

Dr. Boehmer reported consulting for Pfizer. Dr. Sabari reported consulting and advisory board membership for multiple pharmaceutical companies.

A recent survey shows that fewer than half of community oncologists use biomarker testing to guide patient discussions about treatment, which compares with 73% of academic clinicians.

The findings, reported at the 2020 World Conference on Lung Cancer, which was rescheduled for January 2021, highlight the potential for unequal application of the latest advances in cancer genomics and targeted therapies throughout the health care system, which could worsen existing disparities in underserved populations, according to Leigh Boehmer, PharmD, medical director for the Association of Community Cancer Centers, Rockville, Md.

The survey – a mixed-methods approach for assessing practice patterns, attitudes, barriers, and resource needs related to biomarker testing among clinicians – was developed by the ACCC in partnership with the LUNGevity Foundation and administered to clinicians caring for patients with non–small cell lung cancer who are uninsured or covered by Medicaid.

Of 99 respondents, more than 85% were physicians and 68% worked in a community setting. Only 40% indicated they were very familiar or extremely familiar with 2018 Molecular Testing Guidelines for Lung Cancer from the College of American Pathologists, the International Association for the Study of Lung Cancer, and the Association for Molecular Pathology.

Clinicians were most confident about selecting appropriate tests to use, interpreting test results, and prognosticating based on test results, with 77%, 74%, and 74%, respectively, saying they are very confident or extremely confident in those areas. They were less confident about determining when to order testing and in coordinating care across the multidisciplinary team, with 59% and 64%, respectively, saying they were very confident or extremely confident in those areas, Dr. Boehmer reported at the conference.

Immunotherapy for cancer patients with poor PS needs a rethink

Article Type
Changed
Fri, 12/16/2022 - 12:16

A review of patients with advanced cancer and poor performance status (PS) has shown that objective responses to immunotherapy are rare and that overall survival (OS) is extremely limited. The findings have prompted an expert to argue against the use of immunotherapy for such patients, who may have little time left and very little chance of benefiting.

“It is quite clear from clinical practice that most patients with limited PS do very poorly and do not benefit from immune check point inhibitors (ICI),” Jason Luke, MD, UPMC Hillman Cancer Center and the University of Pittsburgh, said in an email.

“So, my strong opinion is that patients should not be getting an immunotherapy just because it might not cause as many side effects as chemotherapy,” he added.

“Instead of giving an immunotherapy with little chance of success, patients and families deserve to have a direct conversation about what realistic expectations [might be] and how we as the oncology community can support them to achieve whatever their personal goals are in the time that they have left,” he emphasized.

Dr. Luke was the lead author of an editorial in which he commented on the study. Both the study and the editorial were published online in JCO Oncology Practice.
 

Variety of cancers

The study was conducted by Mridula Krishnan, MD, Nebraska Medicine Fred and Pamela Buffett Cancer Center, Omaha, Nebraska, and colleagues.

The team reviewed 257 patients who had been treated with either a programmed cell death protein–1 inhibitor or programmed cell death–ligand-1 inhibitor for a variety of advanced cancers. The drugs included pembrolizumab (Keytruda), nivolumab (Opdivo), atezolizumab (Tecentique), durvalumab (Imfinzi), and avelumab (Bavencio).

Most of the patients (71%) had good PS, with an Eastern Cooperative Oncology Group (ECOG) PS of 0-1 on initiation of immunotherapy; 29% of patients had poor PS, with an ECOG PS of greater than or equal to 2.

“The primary outcome was OS stratified by ECOG PS 0-1 versus ≥2,” note the authors. Across all tumor types, OS was superior for patients in the ECOG 0-1 PS group, the investigators note. The median OS was 12.6 months, compared with only 3.1 months for patients in the ECOG greater than or equal to 2 group (P < .001).

Moreover, overall response rates for patients with a poor PS were low. Only 8%, or 6 of 75 patients with an ECOG PS of greater than or equal to 2, achieved an objective response by RECIST criteria.

This compared to an overall response rate of 23% for patients with an ECOG PS of 0-1, the investigators note (P = .005).

Interestingly, the hospice referral rate for patients with a poor PS (67%) was similar to that of patients with a PS of 1-2 (61.9%), Dr. Krishnan and colleagues observe.

Those with a poor PS were more like to die in-hospital (28.6%) than were patients with a good PS (15.1%; P = .035). The authors point out that it is well known that outcomes with chemotherapy are worse among patients who experience a decline in functional reserve, owing to increased susceptibility to toxicity and complications.

“Regardless of age, patients with ECOG PS >2 usually have poor tolerability to chemotherapy, and this correlates with worse survival outcome,” they emphasize. There is as yet no clear guidance regarding the impact of PS on ICI treatment response, although “there should be,” Dr. Luke believes.

“In a patient with declining performance status, especially ECOG PS 3-4 but potentially 2 as well, there is little likelihood that the functional and immune reserve of the patient will be adequate to mount a robust antitumor response,” he elaborated.

“It’s not impossible, but trying for it should not come at the expense of engaging about end-of-life care and maximizing the palliative opportunities that many only have a short window of time in which to pursue,” he added.

Again, Dr. Luke strongly believes that just giving an ICI without engaging in a frank conversation with the patient and their families – which happens all too often, he feels – is absolutely not the way to go when treating patients with a poor PS and little time left.

“Patients and families might be better served by having a more direct and frank conversation about what the likelihood [is] that ICI therapy will actually do,” Dr. Luke stressed.

In their editorial, Dr. Luke and colleagues write: “Overall, we as an oncology community need to improve our communication with patients regarding goals of care and end-of-life considerations as opposed to reflexive treatment initiation,” he writes.

“Our duty, first and foremost, should focus on the person sitting in front of us – taking a step back may be the best way to move forward with compassionate care,” they add.

The authors and editorialists have disclosed no relevant financial relationships.

New guidance on preventing cutaneous SCC in solid organ transplant patients

Article Type
Changed
Mon, 09/13/2021 - 08:00

An expert panel of 48 dermatologists from 13 countries has developed recommendations to guide efforts aimed at preventing cutaneous squamous cell carcinoma (CSCC) in solid organ transplant recipients.

The recommendations were published online on Sept. 1 in JAMA Dermatology.

Because of lifelong immunosuppression, solid organ transplant recipients (SOTRs) have a risk of CSCC that is 20-200 times higher than in the general population and despite a growing literature on prevention of CSCC in these patients, uncertainty remains regarding best practices for various patient scenarios.

Paul Massey, MD, MPH, of the department of dermatology, Brigham and Women’s Hospital, Boston, and colleagues used a Delphi process to identify consensus-based medical management recommendations for prevention of CSCC in SOTRs.

The survey design was guided by a novel actinic damage and skin cancer index (AD-SCI) made up of six ordinal stages corresponding to an increasing burden of actinic damage and CSCC.

The AD-SCI stage-based recommendations were established when consensus was reached (80% or higher concordance) or near consensus was reached (70%-80% concordance) among panel members.

For five of the six AD-SCI stages, the panel was able to make recommendations. Key recommendations include:
 

  • Cryotherapy for scattered AK.
  • Field therapy for AK when grouped in one site, unless AKs are thick, in which case field therapy and cryotherapy are recommended.
  • Combination lesion-directed and field therapy with fluorouracil for field cancerized skin.
  • Initiation of acitretin therapy and discussion of immunosuppression reduction or modification for patients who develop multiple CSCCs at a high rate (10 per year) or develop high-risk CSCC (defined by a tumor with roughly ≥20% risk of nodal metastasis). The panel did not make a recommendation as to the best immunosuppression modification strategy to pursue.

Lingering questions

The panel was unable to reach consensus on a recommendation for SOTRs with a first low-risk CSCC, reflecting “clinical equipoise” in this situation and the need for further study in this clinical scenario, they say.

The panel did not make a recommendation for use of nicotinamide or capecitabine in any of the six stages, which is “notable,” they acknowledge, given results of a double-blind randomized controlled trial in immunocompetent patients demonstrating benefit in preventing AKs and CSCCs, as reported previously.

Nearly three-quarters of the panel felt that a lack of efficacy data specifically for the SOTR population limited their use of nicotinamide. “Given the low cost, high safety, and demonstration of CSCC reduction in non-SOTRs, nicotinamide administration may be an area for further consideration and expanded study,” the panel wrote.

As for capecitabine, the panel notes that case series in SOTRs have found efficacy for chemoprevention, but randomized controlled studies are lacking. More than half of the panel noted that they did not have routine access to capecitabine in their practice.



The panel recommended routine skin surveillance and sunscreen use for all patients.

“These recommendations reflect consensus among expert transplant dermatologists and the incorporation of limited and sometimes contradictory evidence into real-world clinical experience across a range of CSCC disease severity,” the panel said.

“Areas of consensus may aid physicians in establishing best practices regarding prevention of CSCC in SOTRs in the setting of limited high level of evidence data in this population,” they added.

This research had no specific funding. Author disclosures included serving as a consultant to Regeneron, Sanofi, and receiving research funding from Castle Biosciences, Regeneron, Novartis, and Genentech. A complete list of disclosures for panel members is available with the original article.

Verrucous Carcinoma in a Wounded Military Amputee

Article Type

Fri, 08/20/2021 - 14:40

 

To the Editor:

Verrucous carcinoma is a rare, well-differentiated, locally aggressive squamous cell carcinoma first described by Ackerman in 1948.1 There are 4 main clinicopathologic types: oral florid papillomatosis or Ackerman tumor, giant condyloma acuminatum or Buschke-Lowenstein tumor, plantar verrucous carcinoma, and cutaneous verrucous carcinoma.2,3 Historically, most patients are older white men. The lesion commonly occurs in sites of inflammation4 or chronic irritation/trauma. Clinically, patients present with a slowly enlarging, exophytic, verrucous plaque violating the skin, fascia, and occasionally bone. Although these lesions have little tendency to metastasize, substantial morbidity can be seen due to local invasion. Despite surgical excision, recurrence is not uncommon and is associated with a poor prognosis and higher infiltrative potential.5

A 45-year-old male veteran initially presented to our dermatology clinic with a 4-cm, macerated, verrucous plaque on the left lateral ankle in the area of a skin graft placed during a prior limb salvage surgery (Figure 1). The patient experienced a traumatic blast injury while deployed 7 years prior with a subsequent right-sided below-the-knee amputation and left lower limb salvage. The lesion was clinically diagnosed as verruca vulgaris and treated with daily salicylic acid. Six weeks after the initial presentation, the lesion remained largely unchanged. A biopsy subsequently was obtained to confirm the diagnosis. At that time, the histopathology was consistent with verruca vulgaris without evidence of carcinoma. Due to the persistence of the lesion, lack of improvement with topical treatment, and overall size, the patient opted for surgical excision.

A year later, the lesion was excised again by orthopedic surgery, and the tissue was submitted for histopathologic evaluation, which was suggestive of a verrucous neoplasm with some disagreement on whether it was consistent with verrucous hyperplasia or verrucous carcinoma. Following excision, the patient sustained a nonhealing chronic ulcer that required wound care for a total of 6 months. The lesion recurred a year later and was surgically excised a third time. A split-thickness skin graft was utilized to repair the defect. Histopathology again was consistent with verrucous carcinoma. With a fourth and final recurrence of the verrucous plaque 6 months later, the patient elected to undergo a left-sided below-the-knee amputation.



Verrucous carcinoma can represent a diagnostic dilemma, as histologic sections may mimic benign entities. The features of a well-differentiated squamous epithelium with hyperkeratosis, papillomatosis, and acanthosis can be mistaken for verruca vulgaris, keratoacanthoma, and pseudoepitheliomatous hyperplasia,6 which are characteristic of verrucous hyperplasia. Accurate diagnosis can be difficult with a superficial biopsy because of the mature appearance of the epithelium,7 prompting the need for multiple and deeper biopsies8 to include sampling of the base of the hyperplastic epithelium in which the characteristic bulbous pushing growth pattern of the rete ridges is visualized. Precise histologic diagnosis can be further confounded by external mechanical factors, such as pressure, which can distort the classic histopathology.7 The histopathologic features leading to the diagnosis of verrucous carcinoma in our specimen were minimal squamous atypia present in a predominantly exophytic squamous proliferation with human papillomavirus cytopathic effect and focal endophytic pushing borders by rounded bulbous rete ridges into the mid and deep dermis (Figure 2).

Figure 2. Biopsy of the lesion demonstrated minimal squamous atypia in a predominantly exophytic squamous proliferation, with focal endophytic pushing borders by rounded bulbous rete ridges into the mid and deep dermis (H&E, original magnification ×40).


Diagnostic uncertainty can delay surgical excision and lead to progression of verrucous carcinoma. Unfortunately, even with appropriate surgical intervention, recurrence has been documented; therefore, close clinical follow-up is recommended. The tumor spreads by local invasion and may follow the path of least resistance.4 In our patient, the frequent tissue manipulation may have facilitated aggressive infiltration of the tumor, ultimately resulting in the loss of his remaining leg. Therefore, it is important for clinicians to recognize that verrucous carcinoma, especially one that develops on a refractory ulcer or scar tissue, may be a complex malignant neoplasm that requires extensive treatment at onset to prevent the amputation of a limb.

To the Editor:

Verrucous carcinoma is a rare, well-differentiated, locally aggressive squamous cell carcinoma first described by Ackerman in 1948.1 There are 4 main clinicopathologic types: oral florid papillomatosis or Ackerman tumor, giant condyloma acuminatum or Buschke-Lowenstein tumor, plantar verrucous carcinoma, and cutaneous verrucous carcinoma.2,3 Historically, most patients are older white men. The lesion commonly occurs in sites of inflammation4 or chronic irritation/trauma. Clinically, patients present with a slowly enlarging, exophytic, verrucous plaque violating the skin, fascia, and occasionally bone. Although these lesions have little tendency to metastasize, substantial morbidity can be seen due to local invasion. Despite surgical excision, recurrence is not uncommon and is associated with a poor prognosis and higher infiltrative potential.5

Medical students lead event addressing disparity in skin cancer morbidity and mortality

– Those who self-identify as Hispanic or Black have a lower self-perceived risk of melanoma. In fact, people of color receive little to no information concerning skin cancer risks and prevention strategies and experience a longer time from diagnosis to definitive surgery, resulting in far worse outcomes, compared with non-Hispanic Whites.

Volunteers and participants at the Learn2Derm skin cancer prevention fair, on July 10, in Ward 8, Washington, D.C.

This disparity is reflected in statistics showing that the average 5-year survival rate for melanoma is 92% in White patients but drops down to 67% in Black patients. Low income is also a contributing factor: Patients with lower incomes experience greater difficulty accessing health care and have greater time to diagnosis and a worse prognosis and survival time with melanoma. Despite economic advancements, Black Americans are still economically deprived when compared with White Americans.

This reality is what led Sarah Millan, a 4th-year medical student at George Washington University, Washington, to focus on the Ward 8 community in Washington – one of the poorest regions in our nation’s capital – well known for limited access to medical care and referred to as a health care desert. “Ward 8 has a population that is 92% Black and does not have a single dermatology clinic in the vicinity – my vision was to bring together the community through an enjoyable attraction conducive to the delivery of quality dermatologic care and education to a community that has none,” said Ms. Millan.

This low-resource population that is socioeconomically and geographically isolated is likely unaware of skin cancer risks, prevention strategies, and signs or symptoms that would warrant a visit to the dermatologist.

In light of these inequalities, “Learn2Derm: Skin Cancer Prevention Fair” was born – an attempt to close this disparity through educational interventions focused on skin cancer presentation, prevention, and early detection, while also exploring the attitudes and behaviors around skin cancer and sunscreen use in the community through data collected from optional surveys.

On Saturday, July 10, 2021, dermatologists from George Washington University, department of dermatology and medical students from George Washington School of Medicine and Health Sciences and Howard University College of Medicine in Washington, transformed Martha’s Outfitters in Ward 8 into a decorated, music-filled venue. Part of the Ward 8 council member’s 40 Days of Peace initiative, the Learn2Derm fair provided free skin cancer screenings by dermatologists, while students staffed various stations, delivering fun and interactive educational lessons organized by Ms. Millan under the mentorship of Adam Friedman, MD, chair of dermatology at George Washington University.

“It is our responsibility to support our communities through care, but even more importantly, combating misinformation and misperceptions that could interfere with healthy living,” said Dr. Friedman.

Activities included arts and crafts sponsored by the American Academy of Dermatology Good Skin Knowledge lessons, games with giveaways sponsored by the Polka Dot Mama Melanoma Foundation and IMPACT Melanoma, Skin Analyzers (to see where sunscreen was applied, and where it was missed) supplied by the Melanoma Research Foundation (MRF) and Children’s Melanoma Prevention Foundation (CMPF), and even Viva Vita virtual reality headsets that are catered towards the senior population – but enjoyable to anyone. Prizes and giveaways ranged from ultraviolet-induced color-changing bracelets and Frisbees, SPF lip balms, sunglasses – and of course – an abundant supply of free sunscreen. Many community members expressed their gratitude for this event and were impressed by the education that was enlivened through interactive games, activities, and giveaways. One participant shared the news of the event with a friend who immediately stopped what she was doing to come by for some education, a skin cancer screening, and free skincare products. While parents went in for a free skin cancer screening, their children were supervised by medical student volunteers as they colored or participated in other stations.

Ms. Millan’s involvement with the National Council on Skin Cancer Prevention’s Skin Smart Campus Initiative facilitated the support and partnership with multiple national organizations central to the event’s success, including the AAD, the National Council on Skin Cancer Prevention, the Skin Cancer Foundation, IMPACT Melanoma, Polka Dot Mama Melanoma Foundation, MRF, and CMPF. The donations of these organizations and businesses in the sun protection industry, along with faculty and medical students who share a passion for delivering dermatologic care and resources brought this exciting plan into fruition. The aim of Learn2Derm is not for this to be a single event, but rather the first of many that will continue to deliver this type of care to a community that is in need of greater dermatologic attention – an ongoing occurrence that can have a lasting impact on the Ward 8 community.

Major sunscreen manufacturers that donated sunscreen for this event included Avène, Black Girl Sunscreen, CeraVe, Cetaphil, EltaMD, and Neutrogena. Coolibar, which specializes in sun-protective clothing, also made a donation of multistyle hats, gaiters, and clothes for attendees.

Activities included arts and crafts sponsored by the American Academy of Dermatology Good Skin Knowledge lessons, games with giveaways sponsored by the Polka Dot Mama Melanoma Foundation and IMPACT Melanoma, Skin Analyzers (to see where sunscreen was applied, and where it was missed) supplied by the Melanoma Research Foundation (MRF) and Children’s Melanoma Prevention Foundation (CMPF), and even Viva Vita virtual reality headsets that are catered towards the senior population – but enjoyable to anyone. Prizes and giveaways ranged from ultraviolet-induced color-changing bracelets and Frisbees, SPF lip balms, sunglasses – and of course – an abundant supply of free sunscreen. Many community members expressed their gratitude for this event and were impressed by the education that was enlivened through interactive games, activities, and giveaways. One participant shared the news of the event with a friend who immediately stopped what she was doing to come by for some education, a skin cancer screening, and free skincare products. While parents went in for a free skin cancer screening, their children were supervised by medical student volunteers as they colored or participated in other stations.

Ms. Millan’s involvement with the National Council on Skin Cancer Prevention’s Skin Smart Campus Initiative facilitated the support and partnership with multiple national organizations central to the event’s success, including the AAD, the National Council on Skin Cancer Prevention, the Skin Cancer Foundation, IMPACT Melanoma, Polka Dot Mama Melanoma Foundation, MRF, and CMPF. The donations of these organizations and businesses in the sun protection industry, along with faculty and medical students who share a passion for delivering dermatologic care and resources brought this exciting plan into fruition. The aim of Learn2Derm is not for this to be a single event, but rather the first of many that will continue to deliver this type of care to a community that is in need of greater dermatologic attention – an ongoing occurrence that can have a lasting impact on the Ward 8 community.

Major sunscreen manufacturers that donated sunscreen for this event included Avène, Black Girl Sunscreen, CeraVe, Cetaphil, EltaMD, and Neutrogena. Coolibar, which specializes in sun-protective clothing, also made a donation of multistyle hats, gaiters, and clothes for attendees.

The four most effective treatments for long-term clearance of actinic keratosis (AK) are photodynamic therapy with aminolevulinate (ALA-PDT); imiquimod, 5%; photodynamic therapy with methyl aminolevulinate (MAL-PDT); and cryosurgery, results from a systemic review and meta-analysis suggest.

To date, many studies have reported that “most interventions are superior to placebo in terms of lesion clearance and improving the cosmetic image,” corresponding author Markus V. Heppt, MD, MSc, and colleagues wrote in a study published online Aug. 4, 2021, in JAMA Dermatology.

“However, most randomized clinical trials (RCTs) and meta-analyses focused on short-term outcomes that are evaluated within 3-6 months after treatment, although AK is increasingly being considered a chronic condition and reducing the incidence of cSCC [cutaneous squamous cell carcinoma] should be the ultimate goal of treatment,” they said. In addition, most treatments have been compared with placebo “and head-to-head comparisons are widely lacking, limiting the possibility to cross compare distinct active treatments. To this end, no evidence-based recommendation regarding the long-term efficacy of interventions for AK exists.”

To determine the long-term clearance rates of treatments used in adults with AK, a precursor of cSCC, Dr. Heppt, of the department of dermatology at University Hospital Erlangen (Germany), and colleagues drew from 15 randomized clinical trials that reported sustained clearance rates after at least 12 months of treatment and were published up to April 6, 2020. They conducted the review by following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guideline and its extension for network meta-analyses (PRIMSA-NMA) and using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) process to determine the certainty of the evidence for network meta-analyses.

The study population included 4,252 patients. Among 10 studies included in a network meta-analysis for the outcome of participant complete clearance, ALA-PDT showed the most favorable risk ratio profile, compared with placebo (RR, 8.06; moderate-quality evidence on GRADE), followed by imiquimod, 5% (RR, 5.98; very-low-quality evidence on GRADE); MAL-PDT (RR, 5.95; low-quality evidence on GRADE); and cryosurgery (RR, 4.76; very-low-quality evidence on GRADE).

ALA-PDT had the highest RR in the network meta-analyses for lesion-specific clearance (RR, 5.08; moderate-quality evidence on GRADE).



“Although ALA-PDT showed the most favorable RR and was ranked best among all interventions, the relative efficacy values and treatment rankings must be interpreted with caution,” because of the low certainty of evidence and few direct, head-to-head comparisons, the authors emphasized. “In particular, it remains elusive how to translate the distinct RR values into clinical relevance. We are hesitant to derive hierarchical or algorithmic treatment recommendations from our results.”

“The current meta-analysis notes that there are conflicting results in different studies,” said Christine Ko, MD, professor of dermatology and pathology at Yale University, New Haven, Conn. who was asked to comment on the study. “Sustained participant complete clearance of actinic keratoses at 12 months is used as an outcome measure, although the authors comment that prevention/reduction of squamous cell carcinoma might be the more valid outcome measure.”

In her clinical experience, Dr. Ko said that patients often have good, sustained clearance of AKs with field treatment using a topical medication like 5-fluorouracil. “Patients can also have a good result with photodynamic therapy,” she said. “The paper’s results therefore do reflect what I have seen in my own practice. I also agree with the authors that, while it is difficult to measure, a meaningful outcome for patients is reduction/prevention of squamous cell carcinoma. It would be useful to have data on which treatment of actinic keratosis is best to reduce/prevent squamous cell carcinoma.”

The authors acknowledged limitations of the study, including the fact that field-directed treatments such as imiquimod, PDT, and fluorouracil were compared with lesion-directed approaches such as cryosurgery, “which may limit the generalizability of our results.” They concluded that their analysis “provides data that might contribute to an evidence-based framework to guide the selection of interventions for AK with proven long-term efficacy and sustained AK clearance.”

The analysis did not include data on tirbanibulin, a first-in-class dual Src kinase and tubulin polymerization inhibitor that was approved by the FDA for the topical treatment of AKs on the face or scalp in December 2020.

Dr. Heppt disclosed that he has been a member of the advisory boards of Almirall Hermal and Sanofi-Aventis and has received speaker’s honoraria from Galderma and Biofrontera. Many of his coauthors also reported having relevant financial disclosures. Dr. Ko reported having no relevant disclosures.

Exploring the Utility of Artificial Intelligence During COVID-19 in Dermatology Practice

Article Type

Fri, 09/24/2021 - 11:08

 

With the need to adapt to the given challenges associated with COVID-19, artificial intelligence (AI) serves as a potential tool in providing access to medical-based diagnosis in a novel way. Artificial intelligence is defined as intelligence harnessed by machines that have the ability to perform what is called cognitive thinking and to mimic the problem-solving abilities of the human mind. Virtual AI in dermatology entails neural network–based guidance that includes developing algorithms to detect skin pathology through photographs.1 To use AI in dermatology, recognition of visual patterns must be established to give diagnoses. These neural networks have been used to classify skin diseases, including cancer, actinic keratosis, and warts.2

AI for Skin Cancer

The use of AI to classify melanoma and nonmelanoma skin cancer has been studied extensively, including the following 2 research projects.

Convolutional Neural Network
In 2017, Stanford University published a study in which a deep-learning algorithm known as a convolutional neural network was used to classify skin lesions.3 The network was trained using a dataset of 129,450 clinical images of 2032 diseases. Its performance was compared to that of 21 board-certified dermatologists on biopsy-proven clinical images with 2 classifications of cases: (1) keratinocyte carcinoma as opposed to benign seborrheic keratosis and (2) malignant melanoma as opposed to benign nevi—the first representing the most common skin cancers, and the second, the deadliest skin cancers. The study showed that the machine could accurately identify and classify skin cancers compared to the work of board-certified dermatologists. The study did not include demographic information, which limits its external validity.3

Dermoscopic Image Classification
A 2019 study by Brinker and colleagues4 showed the superiority of automated dermoscopic melanoma image classifications compared to the work of board-certified dermatologists. For the study, 804 biopsy-proven images of melanoma and nevi (1:1 ratio) were randomly presented to dermatologists for their evaluation and recommended treatment (yielding 19,296 recommendations). The dermatologists classified the lesions with a sensitivity of 67.2% and specificity of 62.2%; the trained convolutional neural network attained both higher sensitivity (82.3%) and higher specificity (77.9%).4

Smartphone Diagnosis of Melanoma

An application of AI has been to use smartphone apps for the diagnosis of melanoma. The most utilized and novel algorithm-based smartphone app that assesses skin lesions for malignancy characteristics is SkinVision. With a simple download from Apple’s App Store, this technology allows a person to check their skin spots by taking a photograph and receiving algorithmic risk-assessment feedback. This inexpensive software ($51.78 a year) also allows a patient’s physician to assess the photograph and then validate their assessment by comparing it with the algorithmic analysis that the program provides.5

A review of SkinVision conducted by Thissen and colleagues6 found that, in a hypothetical population of 1000 adults of whom 3% actually had melanoma, 4 of those 30 people would not have been flagged as at “high risk” by SkinVision. There also was a high false-positive rate with the app, with more than 200 people flagged as at high risk. The analysis pegged SkinVision as having a sensitivity of 88% and specificity of 79%.6

In summary, systematic review of diagnostic accuracy has shown that, although there is accuracy in AI analyses, it should be used only as a guide for health care advice due to variability in algorithm performance.7

Utility of AI in Telehealth

Artificial intelligence algorithms could be created to ensure telehealth image accuracy, stratify risk, and track patient progress. With teledermatology visits on the rise during the COVID-19 pandemic, AI algorithms could ensure that photographs of appropriate quality are taken. Also, patients could be organized by risk factors with such algorithms, allowing physicians to save time on triage and stratification. Algorithms also could be used to track a telehealth patient’s treatment and progress.8

Furthermore, there is a need for an algorithm that has the ability to detect, quantify, and monitor changes in dermatologic conditions using images that patients have uploaded. This capability will lead to creation of a standardized quantification scale that will allow physicians to virtually track the progression of visible skin pathologies.

Hazards of Racial Bias in AI

Artificial intelligence is limited by racial disparity bias seen in computerized medicine. For years, the majority of dermatology research, especially in skin cancer, has been conducted on fairer-skinned populations. This bias has existed at the expense of darker-skinned patients, whose skin conditions and symptoms present differently,9 and reflects directly in available data sets that can be used to develop AI algorithms. Because these data are inadequate to the task, AI might misdiagnose skin cancer in people of color or miss an existing condition entirely.10 Consequently, the higher rate of skin cancer mortality that is reported in people of color is likely to persist with the rise of AI in dermatology.11 A more representative database of imaged skin lesions needs to be utilized to create a diversely representative and applicable data set for AI algorithms.12

Benefits of Conversational Agents

Another method by which AI could be incorporated into dermatology is through what is known as a conversational agent (CA)—AI software that engages in a dialogue with users by interpreting their voice and replying to them through text, image, or voice.13 Conversational agents facilitate remote patient management, allow clinicians to focus on other functions, and aid in data collection.14 A 2014 study showed that patients were significantly more likely to disclose history and emotions when informed they were interacting with a CA than with a human clinician (P=.007).15 Such benefits could be invaluable in dermatology, where emotions and patient perceptions of skin conditions play into the treatment process.

However, some evidence showed that CAs cannot respond to patients’ statements in all circumstances.16 It also is unclear how well CAs recognize nuanced statements that might signal potential harm. This fits into the greater theme of a major problem with AI: the lack of a reliable response in all circumstances.13

Final Thoughts

The practical implementations of AI in dermatology are still being explored. Given the uncertainty surrounding the COVID-19 pandemic and the future of patient care, AI might serve as an important asset in assisting with the diagnosis and treatment of dermatologic conditions, physician productivity, and patient monitoring.

A review of SkinVision conducted by Thissen and colleagues6 found that, in a hypothetical population of 1000 adults of whom 3% actually had melanoma, 4 of those 30 people would not have been flagged as at “high risk” by SkinVision. There also was a high false-positive rate with the app, with more than 200 people flagged as at high risk. The analysis pegged SkinVision as having a sensitivity of 88% and specificity of 79%.6

In summary, systematic review of diagnostic accuracy has shown that, although there is accuracy in AI analyses, it should be used only as a guide for health care advice due to variability in algorithm performance.7

Utility of AI in Telehealth

Artificial intelligence algorithms could be created to ensure telehealth image accuracy, stratify risk, and track patient progress. With teledermatology visits on the rise during the COVID-19 pandemic, AI algorithms could ensure that photographs of appropriate quality are taken. Also, patients could be organized by risk factors with such algorithms, allowing physicians to save time on triage and stratification. Algorithms also could be used to track a telehealth patient’s treatment and progress.8

Furthermore, there is a need for an algorithm that has the ability to detect, quantify, and monitor changes in dermatologic conditions using images that patients have uploaded. This capability will lead to creation of a standardized quantification scale that will allow physicians to virtually track the progression of visible skin pathologies.

Hazards of Racial Bias in AI

Artificial intelligence is limited by racial disparity bias seen in computerized medicine. For years, the majority of dermatology research, especially in skin cancer, has been conducted on fairer-skinned populations. This bias has existed at the expense of darker-skinned patients, whose skin conditions and symptoms present differently,9 and reflects directly in available data sets that can be used to develop AI algorithms. Because these data are inadequate to the task, AI might misdiagnose skin cancer in people of color or miss an existing condition entirely.10 Consequently, the higher rate of skin cancer mortality that is reported in people of color is likely to persist with the rise of AI in dermatology.11 A more representative database of imaged skin lesions needs to be utilized to create a diversely representative and applicable data set for AI algorithms.12

Benefits of Conversational Agents

Another method by which AI could be incorporated into dermatology is through what is known as a conversational agent (CA)—AI software that engages in a dialogue with users by interpreting their voice and replying to them through text, image, or voice.13 Conversational agents facilitate remote patient management, allow clinicians to focus on other functions, and aid in data collection.14 A 2014 study showed that patients were significantly more likely to disclose history and emotions when informed they were interacting with a CA than with a human clinician (P=.007).15 Such benefits could be invaluable in dermatology, where emotions and patient perceptions of skin conditions play into the treatment process.

However, some evidence showed that CAs cannot respond to patients’ statements in all circumstances.16 It also is unclear how well CAs recognize nuanced statements that might signal potential harm. This fits into the greater theme of a major problem with AI: the lack of a reliable response in all circumstances.13

Final Thoughts

The practical implementations of AI in dermatology are still being explored. Given the uncertainty surrounding the COVID-19 pandemic and the future of patient care, AI might serve as an important asset in assisting with the diagnosis and treatment of dermatologic conditions, physician productivity, and patient monitoring.

 

With the need to adapt to the given challenges associated with COVID-19, artificial intelligence (AI) serves as a potential tool in providing access to medical-based diagnosis in a novel way. Artificial intelligence is defined as intelligence harnessed by machines that have the ability to perform what is called cognitive thinking and to mimic the problem-solving abilities of the human mind. Virtual AI in dermatology entails neural network–based guidance that includes developing algorithms to detect skin pathology through photographs.1 To use AI in dermatology, recognition of visual patterns must be established to give diagnoses. These neural networks have been used to classify skin diseases, including cancer, actinic keratosis, and warts.2

AI for Skin Cancer

The use of AI to classify melanoma and nonmelanoma skin cancer has been studied extensively, including the following 2 research projects.

Convolutional Neural Network
In 2017, Stanford University published a study in which a deep-learning algorithm known as a convolutional neural network was used to classify skin lesions.3 The network was trained using a dataset of 129,450 clinical images of 2032 diseases. Its performance was compared to that of 21 board-certified dermatologists on biopsy-proven clinical images with 2 classifications of cases: (1) keratinocyte carcinoma as opposed to benign seborrheic keratosis and (2) malignant melanoma as opposed to benign nevi—the first representing the most common skin cancers, and the second, the deadliest skin cancers. The study showed that the machine could accurately identify and classify skin cancers compared to the work of board-certified dermatologists. The study did not include demographic information, which limits its external validity.3

Dermoscopic Image Classification
A 2019 study by Brinker and colleagues4 showed the superiority of automated dermoscopic melanoma image classifications compared to the work of board-certified dermatologists. For the study, 804 biopsy-proven images of melanoma and nevi (1:1 ratio) were randomly presented to dermatologists for their evaluation and recommended treatment (yielding 19,296 recommendations). The dermatologists classified the lesions with a sensitivity of 67.2% and specificity of 62.2%; the trained convolutional neural network attained both higher sensitivity (82.3%) and higher specificity (77.9%).4

Smartphone Diagnosis of Melanoma

An application of AI has been to use smartphone apps for the diagnosis of melanoma. The most utilized and novel algorithm-based smartphone app that assesses skin lesions for malignancy characteristics is SkinVision. With a simple download from Apple’s App Store, this technology allows a person to check their skin spots by taking a photograph and receiving algorithmic risk-assessment feedback. This inexpensive software ($51.78 a year) also allows a patient’s physician to assess the photograph and then validate their assessment by comparing it with the algorithmic analysis that the program provides.5

A review of SkinVision conducted by Thissen and colleagues6 found that, in a hypothetical population of 1000 adults of whom 3% actually had melanoma, 4 of those 30 people would not have been flagged as at “high risk” by SkinVision. There also was a high false-positive rate with the app, with more than 200 people flagged as at high risk. The analysis pegged SkinVision as having a sensitivity of 88% and specificity of 79%.6

One in three cancer articles on social media has wrong info

Article Type

Wed, 01/04/2023 - 17:17

One in three of the most popular news and feature articles on social media about the treatment of the four leading cancers in the United States contains misinformation, and the majority of those have the potential to harm patients, according to a new analysis.

Of the 200 most popular articles (50 each for prostate, lung, breast, and colorectal cancer), about a third (32.5%, n = 65) contained misinformation.

Among these articles containing misinformation, 76.9% (50/65) contained harmful information.

“The Internet is a leading source of health misinformation,” the study authors wrote. This is “particularly true for social media, where false information spreads faster and more broadly than fact-checked information,” they said, citing other research.

“We need to address these issues head on,” said lead author Skyler Johnson, MD, of the University of Utah’s Huntsman Cancer Institute in Salt Lake City.

“As a medical community, we can’t ignore the problem of cancer misinformation on social media or ask our patients to ignore it. We must empathize with our patients and help them when they encounter this type of information,” he said in a statement. “My goal is to help answer their questions, and provide cancer patients with accurate information that will give them the best chance for the best outcome.”

The study was published online July 22 in the Journal of the National Cancer Institute.

The study period ran from 2018 to 2019, and looked at articles posted on social media platforms Facebook, Reddit, Twitter, or Pinterest. Popularity was measured by engagement with readers, such as upvotes, comments, reactions, and shares.

Some of the articles came from long-established news entities such as CBS News, The New York Times, and medical journals, while others came from fleeting crowdfunding web pages and fledging nontraditional news sites.

One example of popular and harmful misinformation highlighted by Dr. Johnson in an interview was titled, “44-Year-Old Mother Claims CBD Oil Cured Her of Breast Cancer within 5 Months.” Posted on truththeory.com in February 2018, the article is tagged as “opinion” by the publisher and in turn links to another news story about the same woman in the UK’s Daily Mail newspaper.

The ideas and claims in such articles can be very influential, Jennifer L. Lycette, MD, suggested in a recent blog post.

“After 18 years as a cancer doctor, it sadly doesn’t come as a surprise anymore when a patient declines treatment recommendations and instead opts for ‘alternative’ treatment,” she wrote.

Sometimes, misinformation is not sensational but is still effective via clever wording and presentation, observed Brian G. Southwell, PhD, of Duke University, Durham, N.C., who has studied patients and misinformation.

“It isn’t the falsehood that is somehow magically attractive, per se, but the way that misinformation is often framed that can make it attractive,” he said in an interview.

Dr. Southwell recommends that clinicians be proactive about medical misinformation.

“Rather than expect patients to raise concerns without prompting, health care providers should invite conversations about potential misinformation with their patients,” he wrote in a recent essay in the American Journal of Public Health.

In short, ask patients what they know about the treatment of their cancer, he suggests.

“Patients don’t typically know that the misinformation they are encountering is misinformation,” said Dr. Southwell. “Approaching patients with compassion and empathy is a good first step.”
 

 

 

Study details

For the study, reported by Johnson et al., two National Comprehensive Cancer Network panel members were selected as content experts for each of the four cancers and were tasked with reviewing the primary medical claims in each article. The experts then completed a set of ratings to arrive at the proportion of misinformation and potential for harm in each article.

Of the 200 articles, 41.5% were from nontraditional news (digital only), 37.5% were from traditional news sources (online versions of print and/or broadcast media), 17% were from medical journals, 3% were from a crowdfunding site, and 1% were from personal blogs.

This expert review concluded that nearly one-third of the articles contained misinformation, as noted above. The misinformation was described as misleading (title not supported by text or statistics/data do not support conclusion, 28.8%), strength of the evidence mischaracterized (weak evidence portrayed as strong or vice versa, 27.7%) and unproven therapies (not studied or insufficient evidence, 26.7%).

Notably, the median number of engagements, such as likes on Twitter, for articles with misinformation was greater than that of factual articles (median, 2,300 vs. 1,600; P = .05).

In total, 30.5% of all 200 articles contained harmful information. This was described as harmful inaction (could lead to delay or not seeking medical attention for treatable/curable condition, 31.0%), economic harm (out-of-pocket financial costs associated with treatment/travel, 27.7%), harmful action (potentially toxic effects of the suggested test/treatment, 17.0%), and harmful interactions (known/unknown medical interactions with curative therapies, 16.2%).

The median number of engagements for articles with harmful information was statistically significantly greater than that of articles with correct information (median, 2,300 vs. 1,500; P = .007).

A limitation of the study is that it included only the most popular English language cancer articles.

This study was funded in part by the Huntsman Cancer Institute. Dr. Johnson, Dr. Lycette, and Dr. Southwell have disclosed no relevant financial relationships. Some study authors have ties to the pharmaceutical industry.

The ideas and claims in such articles can be very influential, Jennifer L. Lycette, MD, suggested in a recent blog post.

“After 18 years as a cancer doctor, it sadly doesn’t come as a surprise anymore when a patient declines treatment recommendations and instead opts for ‘alternative’ treatment,” she wrote.

Sometimes, misinformation is not sensational but is still effective via clever wording and presentation, observed Brian G. Southwell, PhD, of Duke University, Durham, N.C., who has studied patients and misinformation.

“It isn’t the falsehood that is somehow magically attractive, per se, but the way that misinformation is often framed that can make it attractive,” he said in an interview.

Dr. Southwell recommends that clinicians be proactive about medical misinformation.

“Rather than expect patients to raise concerns without prompting, health care providers should invite conversations about potential misinformation with their patients,” he wrote in a recent essay in the American Journal of Public Health.

In short, ask patients what they know about the treatment of their cancer, he suggests.

“Patients don’t typically know that the misinformation they are encountering is misinformation,” said Dr. Southwell. “Approaching patients with compassion and empathy is a good first step.”
 

 

 

Study details

For the study, reported by Johnson et al., two National Comprehensive Cancer Network panel members were selected as content experts for each of the four cancers and were tasked with reviewing the primary medical claims in each article. The experts then completed a set of ratings to arrive at the proportion of misinformation and potential for harm in each article.

Of the 200 articles, 41.5% were from nontraditional news (digital only), 37.5% were from traditional news sources (online versions of print and/or broadcast media), 17% were from medical journals, 3% were from a crowdfunding site, and 1% were from personal blogs.

This expert review concluded that nearly one-third of the articles contained misinformation, as noted above. The misinformation was described as misleading (title not supported by text or statistics/data do not support conclusion, 28.8%), strength of the evidence mischaracterized (weak evidence portrayed as strong or vice versa, 27.7%) and unproven therapies (not studied or insufficient evidence, 26.7%).

Notably, the median number of engagements, such as likes on Twitter, for articles with misinformation was greater than that of factual articles (median, 2,300 vs. 1,600; P = .05).

In total, 30.5% of all 200 articles contained harmful information. This was described as harmful inaction (could lead to delay or not seeking medical attention for treatable/curable condition, 31.0%), economic harm (out-of-pocket financial costs associated with treatment/travel, 27.7%), harmful action (potentially toxic effects of the suggested test/treatment, 17.0%), and harmful interactions (known/unknown medical interactions with curative therapies, 16.2%).

The median number of engagements for articles with harmful information was statistically significantly greater than that of articles with correct information (median, 2,300 vs. 1,500; P = .007).

A limitation of the study is that it included only the most popular English language cancer articles.

This study was funded in part by the Huntsman Cancer Institute. Dr. Johnson, Dr. Lycette, and Dr. Southwell have disclosed no relevant financial relationships. Some study authors have ties to the pharmaceutical industry.
