At the Skin Disease Education Foundation’s annual Las Vegas Dermatology Seminar, Dr. Gordon said that he uses phototherapy most in patients “who can’t get to all of the spots without it,” and in those whose disease is not having a huge impact on day-to-day life. “In my experience it’s best in people with thinner plaques, though I have some question over whether we can figure out if morphology really does correlate to respond to phototherapy,” he added. “We’re in the process of conducting a study to try and figure that out.”

From an immunologic standpoint, UVB decreases responsiveness of the interleukin-17 pathway and increases both cutaneous and circulating FoxP3+ cells, he said. Activation of p38 mitogen–activated protein kinase during phototherapy inhibits proinflammatory T-cell activation. In Dr. Gordon’s opinion, phototherapy is absolutely contraindicated in patients who have a photosensitivity reaction related to the UVB spectrum, while it is relatively contraindicated in those at high risk for skin cancer, including patients with multiple squamous cell carcinomas and those who have undergone organ transplantation. “I would argue that [the use of] photosensitizing drugs are not a contraindication,” he said. “Would I prefer that someone who’s had 54 [squamous cell carcinomas] not use phototherapy? Of course. But if it’s the only weapon I have, I’ll use it.”

Although clinicians have used phototherapy for about 100 years, early standards for clinical trials were different, compared with the rigor required of those conducted in the current era. Outcomes were not standardized, he said, and they were generally smaller trials that did not incorporate proper monitoring of adverse events. “Even with these weaknesses, we can get a general impression of how well UV works,” he said. In a 6-week, split-body trial of 11 patients from 20 years ago, researchers were able to induce clinical clearing in 82% of patients after narrowband UVB (the type most commonly used today), but in only 9% of patients after broadband UVB treatment (P less than .01) (J Am Acad Dermatol. 1999 Jun;40[6 Pt 1]:893-900).

Most clinicians commence narrowband UVB phototherapy treatment with three sessions per week and safely increase the dose to reach an effective level. Erythema can develop with overdosing. “If a patient can only come in twice weekly [for phototherapy treatment], that is okay,” Dr. Gordon said. “It takes a longer time getting to treatment goals. In my opinion, going down to once a week during the escalating phase of using phototherapy doesn’t work. Three times a week is better than twice a week during the escalating phase, but one time a week isn’t enough.”

Even for maintenance therapy, it remains a question whether limiting phototherapy to once every 2 or 4 weeks is sufficient for disease control. “I let the patient choose, but I like to go down to no less than once a week and hold people steady at that dose,” he said.

Purported risks of narrowband UVB phototherapy include photoaging, sunburn, herpes simplex virus reactivation, loss of the patient’s productive time, and development of skin cancer. “I don’t think we have good data about the effect of phototherapy on photoaging,” Dr. Gordon said. “Loss of productive time is my single biggest [complaint]. People are having trouble getting to work and having bosses who are not pleased with them [leaving work for treatment].”

As for the association between phototherapy and skin cancer, he noted that published studies that show statistical differences all incorporate psoralen-UVA photochemotherapy into their analyses. “There’s really no study that has demonstrated a significant impact on nonmelanoma skin cancers with the use of phototherapy [alone],” Dr. Gordon said. A British study of 3,867 psoriasis patients found no significant association between narrowband UVB treatment and basal cell cancer, squamous cell cancer, or melanoma (Br J Dermatol. 2008 Sep;159[4]:931-5). However, among those who also were treated with psoralen-UVA photochemotherapy, there was a small increase in basal cell cancer.

In a more recent Swedish study of 162 psoriasis patients who were treated with UVB phototherapy, researchers found that, after controlling for age, the risk of skin cancer was associated with the number of treatments, but not with the type of UVB lamp used (Acta Derm Venereol. 2014 Jul;94[4]:425-30). They reported that overall, the risk of malignancy in the UVB-treated patients did not exceed that in the general population.

Dr. Gordon concluded his presentation by noting that home-based UVB phototherapy is gaining in popularity and is comparable with in-office UVB in terms of accuracy and efficacy (BMJ. 2009;338:b1542). Because of convenience and decreased time away from work, he said, “it’s easier for patients ... and it’s probably cheaper in the long run.” The National Psoriasis Foundation web site includes a list of home UVB equipment.

Dr. Gordon disclosed that he is a consultant with AbbVie, Almirall, Amgen, Bristol-Meyers Squibb, Celgene, Dermavant, Eli Lilly, Janssen, Leo, Novartis, Ortho Dermatologics, Pfizer, Sun Pharma, and UCB. He has also received grant/research support from AbbVie, Bristol-Myers Squibb, Celgene, Eli Lilly, Janssen, and Novartis.

LAS VEGAS – New acne treatment options include a tetracycline antibiotic and a recently approved topical formulation of minocycline, according to Linda Stein Gold, MD, who reviewed the data on these two therapies, as well as cannabidiol (CBD) and an androgen receptor antagonist, which are currently in clinical trials, at the Skin Disease Education Foundation’s annual Las Vegas Dermatology Seminar.

When considering antibiotic therapy for patients with moderate to severe acne, sarecycline, approved for that indication in October 2018, has improved anti-inflammatory properties and a narrower spectrum of activity, compared with other tetracycline-class antibiotics used for the condition, according to Dr. Stein Gold, director of dermatology research at Henry Ford Health System in Detroit. In two identically designed, 12-week randomized trials, SC 1401 and SC1402, researchers evaluated the efficacy and safety of an approximate 1.5–mg/kg per day dose of sarecycline in comparison with placebo in patients with moderate to severe facial acne aged 9-45 years (J Drugs Dermatol. 2018 Sept 1;17[9]:987-96). “We started to see separation in the inflammatory lesions as early as week 3, and a nice separation versus placebo over the course of 12 weeks,” said Dr. Stein Gold, one of the study investigators. “In all, 22% of patients got clear or almost clear with monotherapy. That’s fairly good.”

She noted that there was consistency in the reductions of lesion count achieved in both studies. Improvements were seen through to 12 weeks, with statistically significant reduction seen as early as 3 weeks in both studies. Sarecycline was also statistically superior to placebo at every time point studied in both trials.

In order to be judged a successful outcome, the subject had to have a 12-week Investigator’s Global Assessment (IGA) score with a 2-point or greater decrease (improvement) from baseline score on the IGA in each location, for patients who have a baseline IGA of 2 or greater, and to be clear (0) or almost clear (1). The same IGA scale was used for the chest and back assessments as was used for facial acne; the researchers observed statistically significant improvements in IGA score for both chest and back acne across both studies at week 12.

Sarecycline also had a favorable safety profile, with no treatment-emergent vertigo or tinnitus adverse events, she noted. Treatment-emergent vestibular and phototoxic adverse events both occurred in fewer than 1% of sarecycline patients. Among females, rates of yeast infections were low. When she recommends a course of this drug for her patients, “I never overpromise,” she said. “I tell my acne patients, ‘We measure your success in weeks and months, not days.’ I always tell them, ‘Take a selfie today and take a selfie every few weeks. When you come back in, we’ll review your progress and see how things went.’ ”

Researchers have also been studying topical minocycline as a treatment option. Minocycline is a large molecule that Dr. Stein Gold characterized as being “very challenging” to deliver topically. “It’s also challenging to keep it stable in a topical formulation.” However, results from two identical phase 3 trials found 4% topical minocycline foam significantly reduced both inflammatory and noninflammatory lesions and improved IGA scores in patients with moderate to severe acne when treated daily for 12 weeks (J Am Acad Dermatol. 2019 Jan;80[1]:168-77).

“This drug has an interesting vehicle,” said Dr. Stein Gold, who was one of the study investigators. “If you take the vehicle itself and you put it next to sebum, it causes sebum to melt at lower temperatures. Why does this matter? If you’re dissolving sebum, maybe you’re creating an easier pathway for the drug to get delivered into the skin and into the hair follicles. We don’t know all the details.” In the two trials, 15%-31% of patients achieved clearance or near clearance of all lesions. “How did it do in terms of decreasing papules and pustules? It did pretty well,” she said. “We want drugs to meet their match in everything that we do.” In terms of tolerability, skin-related adverse events were reported in fewer than 1% of subjects treated with 4% topical minocycline foam. She noted that by delivering minocycline topically, “we get huge concentrations in the skin, but almost negligible amounts in the systemic circulation, which is important. We want to keep [the drug] in the skin; we don’t want it in our system.”

(The Food and Drug Administration approved minocycline foam 4% in October 2019 for treating inflammatory lesions associated with non-nodular moderate to severe acne).

Another potential treatment on the horizon is cortexolone 17a-propionate, a novel androgen receptor antagonist that inhibits production of lipids and inflammatory cytokines from sebocytes in vitro. “When used around the sebaceous gland, we find that the amount of sebum produced goes down,” she said, noting that phase 3 trials of the agent have been completed.

“We also find that abnormal keratinization subsequently goes down. Just putting this on the skin significantly reduced acne as monotherapy in patients with moderate to severe acne. We were able to get them to clear or almost clear. It worked on comedones, papules, and pustules. Hopefully, it will get FDA approval. This fills the one unmet need we haven’t had topically in terms of decreasing sebum production.”

Clinical trials of CBD are also under way for acne and atopic dermatitis. “It could work for acne because there are some studies showing that might work on sebaceous glands to decrease sebum production,” she said. “CBD has been shown to have positive effects on abnormal keratinization, and it has been shown to have anti-inflammatory effects. Maybe we’ll have another mechanism of action for acne.”

Dr. Gold disclosed that she is on the speakers bureau for Almirall, Galderma, Leo Pharma, Ortho Dermatologics, Pfizer, and Sanofi/Regeneron. She is a consultant for Dermavant, Foamix, Galderma, Leo Pharma, Pfizer, Novartis, Ortho Dermatologics, and holds stock/stock options in AbbVie, Dermavant, Eli Lilly, Foamix, Galderma, Incyte, Leo Pharma, Novartis, Ortho Dermatologics, Pfizer, and Sol-Gel.

Clinical trials of CBD are also under way for acne and atopic dermatitis. “It could work for acne because there are some studies showing that might work on sebaceous glands to decrease sebum production,” she said. “CBD has been shown to have positive effects on abnormal keratinization, and it has been shown to have anti-inflammatory effects. Maybe we’ll have another mechanism of action for acne.”

LAS VEGAS – The way Neal Bhatia, MD, sees it, there is no such thing as a classical presentation of onychomycosis.

“This is where proving your diagnosis is half the battle, even though we are sometimes using empiric therapy in suspected cases,” he said at Skin Disease Education Foundation’s annual Las Vegas Dermatology Seminar. “Prove the diagnosis and get the extra tests necessary.”

According to Dr. Bhatia, director of clinical dermatology research at San Diego-based Therapeutics Clinical Research, tinea unguium, tinea corporis, tinea cruris, and tinea pedis account for more than half of all visits for dermatophytosis. With onychomycosis, the ultimate treatment goal from the standpoint of clinicians is no more fungus, he noted, while the desired endpoint from the standpoint of some patients is normal-looking nails.

“Endpoint failures in a research trial are not the same as what we tell patients in the clinic,” Dr. Bhatia said. “If you have a patient using something topical for 52 weeks and they see two-thirds of their nail improve, you’re not going to say, ‘Stop; you’re a failure now.’ You tell them, ‘Keep going and we’ll keep watching.’ But in the research world, it’s very different when you look at all of the different endpoints that have to be met at the finish line. It’s very important to measure success based on what that patient’s experiencing.”

According to Dr. Bhatia, diagnosing onychomycosis by visual assessment has a sensitivity of 77% and a specificity of 47%, while KOH has a sensitivity between 67% and 93% and specificity between 38% and 78%. PCR, meanwhile, “is quick, but it’s expensive and it has a high false-positive rate. So, in those difficult patients who aren’t responding [to treatment], maybe we can’t just trust our eyes alone [to make a diagnosis].”

Tests such as a KOH stain have low sensitivity, with high costs of more sensitive tests such as the periodic acid–Schiff (PAS) stain. In a recent study, researchers conducted a retrospective cohort analysis of 600 patients with toenail clippings sent for PAS stain during January 2000–December 2013 (J Am Acad Dermatol. 2015 May; 72(5):AB116). They reviewed records to determine which PAS stains were performed to confirm probable clinical diagnosis of onychomycosis.

The researchers found that 30% of toenail clippings were sent for confirmatory PAS staining by dermatologists, compared with 37% by podiatrists and 34% by other clinicians. Of these tests, 75% ordered by dermatologists were positive for fungus, compared with 81% ordered by podiatrists, and 66% ordered by other physicians. “The positive predictive value of clinical suspicion for true onychomycosis was high, and the findings question whether or not a confirmatory test is really necessary,” Dr. Bhatia said.

Preventative strategies to control recurrence of onychomycosis include using maintenance regimens of the recommended antifungal agent, discarding old shoes, alternating wearing different pairs of shoes, periodically disinfecting shoes, washing feet regularly, and alerting the physician to the first sign of infection.

In an effort to investigate strategies to minimize recurrence of onychomycosis, Dr. Bhatia and colleagues evaluated 73 patients over the course of 7 years who were taking either terbinafine or itraconazole (J Drugs Dermatol. 2016;15[3]:279-82). Thirty-six months later, the overall mean recurrence rate among patients was 14%. Prognostic factors influencing recurrence included patient’s family history; lifestyle; underlying physiology (presence of a very thick nail, extensive involvement of the entire nail unit, lateral nail disease and yellow spikes); physical trauma, especially in the elderly; concomitant disease, such as peripheral artery disease and/or diabetes; immunocompromised or immunosuppressed patients, and the presence of tinea pedis.

Based on their analysis, they recommended the following strategies to prevent or limit recurrence: prophylactic use of a topical antifungal twice-weekly for 2-3 years; periodic application of a topical antifungal to plantar surface and/or interdigital spaces; treatment of any coexisting tinea pedis; treating immediate family members; footwear and sock decontamination with antifungal powder; ultraviolet light or ozone; avoidance of activities known to risk spread of disease, such as communal swimming pools.

Dr. Bhatia concluded his presentation by noting that the ideal treatment for onychomycosis would not pose a systemic risk to the liver, heart, or other organs; would not require monitoring of labs; would not require debridement; and would not interact with other drugs. It would also penetrate the nail plate – especially the diseased nail – and would be quick drying.

LAS VEGAS – Cases of cutaneous squamous cell carcinoma (cSCC) are on the rise and are associated with mortality rates similar to melanoma. But even as cSCC draws more attention, two popular staging systems still need refinement, a hematologist-oncologist told dermatologist colleagues.

Both staging systems can be helpful, however, Guilherme Rabinowits, MD, said at Skin Disease Education Foundation’s annual Las Vegas Dermatology Seminar. “The best thing to do is combine both,” he noted, referring to the staging system developed by the Brigham and Women’s Hospital (BWH) and staging systems released in the 7th and 8th editions of the American Joint Committee on Cancer Staging Manual (AJCC 7 and AJCC 8; the latter focuses on head and neck only).

Cutaneous SCC has become a “huge health care burden,” said Dr. Rabinowits of the Miami Cancer Institute/Baptist Health South Florida and Florida International University, Miami. He referred to Medicare data suggesting that cSCC has become as common as basal cell carcinoma (JAMA Dermatol. 2015 Oct;151[10]:1081-6).

While most patients with cSCC have a positive prognosis, he added, the 5-year survival rate among those with the most aggressive disease is only 25%.

As he pointed out, staging systems provide insight into prognosis and treatment, guide appropriate monitoring, and give a common language to clinicians around the world. “When I talk about stage 3, we all understand who we’re talking about,” he said.

Dr. Rabinowits said he formerly worked at BWH so he is especially comfortable with its staging system. It can be appropriate to use both the BWH and AJCC systems at once, he said, noting, however, that studies suggest that the BWH system is superior.

An analysis released in 2014, for example, found that most poor outcomes occurred in patients whose tumors had been rated at lower stages – suggesting less risk – in the AJCC 7 system (J Clin Oncol 2014 Feb 1;32[4]:327-4).

In contrast, the 5% of tumors that were rated at the highest stages in the BWH system – with the highest level of perceived risk – accounted for 70% of nodal metastases and 83% of disease-specific deaths. This group may deserve extra attention in terms of staging and adjuvant treatment in order to improve outcomes, he said.

A study published this year, which compared the BWH and AJCC 8 staging systems, found that they had the same negative predictive value (0.99), while the BWH system showed higher positive predictive value (0.30 vs. 0.17). “Use of BWH tumor classification may minimize the number of patients recommended for radiologic evaluation, close surveillance, and possible adjuvant therapy while still identifying most patients at risk for recurrence, metastasis, and death,” the authors wrote (JAMA Dermatol. 2019 Jul 1;155[7]: 819-25).

As for treatment of localized disease in high-risk patients, Dr. Rabinowits advised turning to a multidisciplinary team for guidance because there are limited prospective randomized data.

Dr. Rabinowits discloses scientific advisory board/consultant relationships (Merck, Regeneron, Sanofi, EMD Serono, Pfizer, and Castle) and shares in Regeneron and Syros Pharmaceuticals. He spoke during a forum on cutaneous malignancies at the meeting.

LAS VEGAS – Dermatologists in Oregon have launched a project that targets melanoma by promoting education and early detection, with the goal of dramatically reducing melanoma deaths in the state of 4.2 million people.

Research shows that “early detection works in melanoma. And awareness seems to be important for the public in detecting melanoma early,” said Sancy Leachman, MD, PhD, professor and chair of the department of dermatology at Oregon Health & Science University, Portland, said at the Skin Disease Education Foundation’s annual Las Vegas Dermatology Seminar.

Dr. Leachman, who is also the John D. Gray chair in melanoma research at OHSU, directs the “War on Melanoma” project, which was inspired by a project in the German state of Schleswig-Holstein that aimed to screen all residents aged over 21 years for melanoma. The project featured an education campaign and population-wide skin cancer screening, and mandated that certain patients – those at high risk and those who needed biopsies – would be referred to dermatologists (Br J Cancer. 2012 Feb 28;106[5]:970-4).

According to Dr. Leachman, the German project was initially a success, and was linked to a 50% decrease in melanoma mortality.

“In Oregon, we thought ‘that sounds very good, so we’re going to try that.’ ” But when it went national, the German project failed, she said, providing lessons for dermatologists in Oregon. “We’re going to try to improve upon the first [German] experiment by making ours controlled with a defined baseline. If it works, the plan is to extend it to select states nationwide.”

The War on Melanoma project was launched earlier this year. According to the university, the program is featuring or will feature the following elements:

• A media campaign called “Start Seeing Melanoma” that’s devoted to educating the public about the early detection of melanoma.
• The release of an iPhone app called MoleMapper that allows users to monitor moles over time.
• Education of medical professionals and partnerships with state-licensed skin care professionals such as massage therapists, cosmetologists, and tattoo artists.

In an interview at the meeting, Dr. Leachman said the project is expected to cost $1 million to $1.5 million over the first 18 months. At that time, she said, researchers will survey residents of Oregon and two control states – Washington and Utah– to see if their knowledge of melanoma has improved, compared with baseline survey results.

In 5 years, researchers plan to begin analyzing melanoma mortality in Oregon and the other states. “We hope to see a decline,” and to link it to increased awareness of melanoma, she said.

Dr. Leachman reported no relevant disclosures. She spoke during a forum on cutaneous malignancies at the meeting.

In a noninferiority trial, researchers in the Netherlands randomized 601 patients with superficial BCCs to one of three medical treatments: two treatments of photodynamic therapy (PDT) 1 week apart (group 1), imiquimod 5 days per week for 6 weeks with no occlusion (group 2), and 5-fluorouracil (5-FU) twice per day for 4 weeks with no occlusion (group 3). They followed the patients for 5 years to see which tumors came back (J Invest Dermatol. 2018 Mar;138[3]:527-33). At 5 years, tumor-free survival was 63% in group 1, 81% in group 2, and 70% in group 3. Based on this analysis the authors concluded that imiquimod is the first choice for noninvasive treatment of most primary BCCs.

“Yes, imiquimod is helpful, but it’s not as good as surgery,” Dr. Epstein said at the Skin Disease Education Foundation’s annual Las Vegas Dermatology Seminar.

Researchers like Dr. Epstein, a dermatologist at Brown & Toland Physicians in Oakland, Calif., have been exploring ways to reduce the recurrence of BCCs in those at high risk. One approach is to stay out of the sun, but that is not practical for most people, “and the data are not very supportive,” he said. “Very few people can actually avoid sunlight. What about topical 5-FU? Suppose you put on 5-FU and then study people for the next year, to see what the likelihood is of them getting a BCC? Why it has taken us so long to do this kind of study is in some ways shameful.” He mentioned one study in which patients at risk of superficial BCC recurrence applied topical 5-FU twice a day for 2-4 weeks. The regimen led to an 11% decrease in the development of BCCs, a trend that did not reach statistical significance.

Another approach to warding off BCC recurrence is to take oral hedgehog pathway inhibitors, which are highly effective. “The problem is, hedgehog pathway inhibitors have side effects that are not catastrophic, but they’re annoying,” Dr. Epstein said. “Patients can lose their hair, they get muscle cramps, and can lose their taste.”

To date, there have been at least three trials evaluating the feasibility of a topical hedgehog pathway inhibitor in adult subjects. In one of the trials, researchers evaluated the efficacy of LDE225, a selective antagonist of Smoothened, in eight patients with nevoid basal cell carcinoma syndrome. They were instructed to apply LDE225 twice per day for 4 weeks (J Invest Dermatol 2011 Aug;131[8]:1735-44). Of 13 BCCs treated in the patients, 12 had a partial to complete response. In fact, eight BCCs had an average of 56% volume reduction but none had complete histologic clearing.

At PellePharm, a biotechnology that Dr. Epstein cofounded, researchers are developing patidegib topical gel, 2%, for the reduction of disease burden of persistently developing BCCs in subjects with Gorlin syndrome. In a phase 3 trial, which just completed recruitment, adults are instructed to apply the gel twice daily to the face for 12 months. The primary endpoint is a comparison between the two treatment arms of the number of new surgically eligible BCCs that develop over the 12-month period. “We want to see if we can reduce the number of surgically eligible BCCs,” Dr. Epstein said. “We’re very hopeful.”

LAS VEGAS – The incidence of melanoma in the United States continues to increase, yet mortality from the disease has been stable and may even be starting to decline, according to data from the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) program.

At the Skin Disease Education Foundation’s annual Las Vegas Dermatology Seminar, Laura Korb Ferris, MD, PhD, said that SEER data project 96,480 new cases of melanoma in 2019, as well as 7,230 deaths from the disease. In 2016, SEER projected 10,130 deaths from melanoma, “so we’re actually projecting a reduction in melanoma deaths,” said Dr. Ferris, director of clinical trials at the University of Pittsburgh Medical Center’s department of dermatology. She added that the death rate from melanoma in 2016 was 2.17 per 100,000 population, a reduction from 2.69 per 100,000 population in 2011, “so it looks like melanoma mortality may be stable,” or even reduced, despite an increase in melanoma incidence.

A study of SEER data between 1989 and 2009 found that melanoma incidence is increasing across all lesion thicknesses (J Natl Cancer Inst. 2015 Nov 12. doi: 10.1093/jnci/djv294). Specifically, the incidence increased most among thin lesions, but there was a smaller increased incidence of thick melanoma. “This suggests that the overall burden of disease is truly increasing, but it is primarily stemming from an increase in T1/T2 disease,” Dr. Ferris said. “This could be due in part to increased early detection.”

Improvements in melanoma-specific survival, she continued, are likely a combination of improved management of T4 disease, a shift toward detection of thinner T1/T2 melanoma, and increased detection of T1/T2 disease.

The SEER data also showed that the incidence of fatal cases of melanoma has decreased since 1989, but only in thick melanomas. This trend may indicate a modest improvement in the management of T4 tumors. “Optimistically, I think increased detection efforts are improving survival by early detection of thin but ultimately fatal melanomas,” Dr. Ferris said. “Hopefully we are finding disease earlier and we are preventing patients from progressing to these fatal T4 melanomas.”

Disparities in melanoma-specific survival also come into play. Men have poorer survival compared with women, whites have the highest survival, and non-Hispanic whites have a better survival than Hispanic whites, Dr. Ferris said, while lower rates of survival are seen in blacks and nonblack minorities, as well as among those in high poverty and those who are separated/nonmarried. Lesion type also matters. The highest survival is seen in those with superficial spreading melanoma, while lower survival is observed in those with nodular melanoma, and acral lentiginous melanoma.

Self-detection of melanoma is another strategy to consider. According to Dr. Ferris, results from multiple studies suggest that about 50% of all melanomas are detected by patients, but the ones they find tend to be thicker than the ones that clinicians detect during office visits. “It would be great if we can get that number higher than 50%,” Dr. Ferris said. “If patients really understood what melanoma is, what it looks like, and when they needed to seek medical attention, perhaps we could get that over 50% and see self-detection of thinner melanomas. That’s a very low-cost intervention.”

Targeted screening efforts that stratify by risk factors and by age “makes screening more efficient and more cost-effective,” she added. She cited one analysis, which found that clinicians need to screen 606 people and conduct 25 biopsies in order to find one melanoma. “That’s very resource intensive,” she said. “However, if you only screened people 50 or older or 65 or older, the number needed to screen goes down, and because your pretest probability is higher, your number need to biopsy goes down as well. If you factor in things like a history of atypical nevi or a personal history of melanoma, those patients are at a higher risk of developing melanoma.”

Dr. Ferris closed her presentation by noting that Australia leads other countries in melanoma prevention efforts. There, the combined incidence of skin cancer is higher than the incidence of any other type of cancer. Four decades ago, Australian health officials launched SunSmart, a series of initiatives intended to reduce skin cancer. These include implementation of policies for hat wearing and shade provision in schools and at work, availability of more effective sunscreens, inclusion of sun protection items as a tax-deductible expense for outdoor workers, increased availability since the 1980s of long-sleeved sun protective swimwear, a ban on the use of indoor tanning since 2014, provision of UV forecasts in weather, and a comprehensive program of grants for community shade structures (PLoSMed. 2019 Oct 8;16[10]:e1002932).

“One approach to melanoma prevention won’t fit all,” she concluded. “We need to focus on prevention, public education to improve knowledge and self-detection.”

Dr. Ferris disclosed that she is a consultant to and an investigator for DermTech and Scibase. She is also an investigator for Castle Biosciences.
