Nonmelanoma Skin Cancer

Recent advances in the immunopathogenesis and therapy of cutaneous T-cell lymphoma (CTCL) have shown great promise for the care of patients with mycosis fungoides (MF) and Sézary syndrome (SS).^1-3 Research into the tumor microenvironment, microbiome, and molecular genetics may yield further information as we strive to develop MF/SS therapy from the bench to the bedside.³ Although progress has been made on multiple fronts in MF, some important—particularly epidemiologic and clinical—questions remain unanswered.

Racial disparities are well known to exist in CTCLs, particularly MF and SS.^4-7 The incidence of MF and SS in the United States is higher in African American/Black patients than in White patients⁴; in addition, MF has an earlier age at onset in Black patients compared with White patients.^4,5 Gender disparities also exist, with relatively more Black females than males affected with MF^4-6; in particular, early-onset MF (ie, <40 years of age) is more common in Black females than Black males.^6,7 According to Surveillance, Epidemiology, and End Results (SEER) data⁴ and the US National Cancer Database,⁵ African American/Black patients with MF have worse outcomes compared with other races (shorter overall survival and higher mortality) and also exhibit higher stages of disease at presentation (stage IIb or higher).⁵ Black race also was found to be a predictor of poor overall survival after accounting for disease characteristics, socioeconomicfactors, and types of treatment. The factors responsible for these racial disparities remain unclear.

A fortuitous collision of interests and technology may have helped to shed light on some of the reasons for these racial disparities in MF. Nearly 2 decades ago, high-quality, whole-body digital cutaneous photography was implemented by the Dermatology Service at Memorial Sloan Kettering Cancer Center Dermatology Service (New York, New York).⁸ Although the standardized 20-pose positioning images initially were used for the follow-up evaluation of patients with multiple nevi and melanomas, we incorporated the same photography technique into our multidisciplinary Cutaneous Lymphoma Clinic at Memorial Sloan Kettering Cancer Center. The multiplicity and clinical heterogeneity of MF lesions is well known, as is the fact that individual MF lesions may develop, respond to therapy, or change independently of other lesions in a given patient. We regularly reviewed these digital images with patients during their visits to assess treatment responses, discussed the need for changes in therapy in the face of progressive disease, and provided encouragement and positive reinforcement for those who improved with time-consuming regimens (eg, phototherapy).

Ultimately, as we became more familiar with looking at images in skin of color, we recognized different clinical features among our Black patients. In the literature, hypopigmented MF is a variant that typically is characterized by CD8⁺-predominant T cells and is seen more frequently in dark-skinned patients.⁹ In contrast, hyperpigmented MF has been considered a relatively rare presentation of MF.¹⁰ However, using only clinical and demographic information, we were able to identify 2 very different prognostic groups: those with hypopigmented lesions and those with only hyperpigmented and/or erythematous skin lesions.¹¹ In our retrospective review of 157 African American/Black MF patients at our institution—122 with early-stage and 35 with late-stage MF—45% of patients had hypopigmented lesions vs 52% with hyperpigmented and/or erythematous lesions but no hypopigmentation. Those with hypopigmentation had superior outcomes, with better overall survival (P=.002) and progression-free survival (P=.014). In addition, more than 80% of patients who progressed or died from disease had hyperpigmented and/or erythematous lesions without hypopigmentation.¹¹

Sometimes we have to go backward to go forward. Going from the bedside to the bench in our Black MF/SS patients—initially through the clinical recognition of prognostically different lesions, and then through clinicopathologic correlation with immunophenotyping and molecular studies—should provide important clues. Further investigation of Black patients who share similar pigmentary phenotypes of MF also may shed light on the pathogenetic mechanisms responsible for these prognostically significant skin findings. Through these efforts, we hope to identify higher-risk patients, which ultimately will lead to earlier intervention, more effective therapeutic regimens, and improved outcomes.

Practice Gap

Reconstruction of a lip defect poses challenges to the dermatologic surgeon. The lip is a free margin, where excess tension can cause noticeable distortion in facial aesthetics. Distortion of that free margin might not only disrupt the appearance of the lip but affect function by impairing oral competency and mobility; therefore, when choosing a method of reconstruction, the surgeon must take free margin distortion into account. Misalignment of the vermilion border upon reconstruction will cause a poor aesthetic result in the absence of free margin distortion. When a surgical defect involves more than one cosmetic subunit of the lip, great care must be taken to repair each subunit individually to achieve the best cosmetic and functional results.

The suitability of traditional approaches to reconstruction of a defect that crosses the vermilion border—healing by secondary intention, primary linear repair, full-thickness wedge repair, partial-thickness wedge repair, and combined cutaneous and mucosal advancement¹—depends on the depth of the lesion.

Clinical Presentation

A 66-year-old woman with a 4×6-mm, invasive, well-differentiated squamous cell carcinoma of the left lower lip was referred for Mohs micrographic surgery. Removal of the tumor required 2 stages to obtain clear margins, leaving a 1.0×1.2-cm defect that crossed the vermilion border (Figure, A). How would you repair this defect?

Selecting a Technique to Close the Surgical Defect

For this patient, we had several options to consider in approaching closure, including several that we rejected. Because the defect crossed cosmetic subunit boundaries, healing by secondary intention was avoided, as it would cause contraction, obliterate the vermilion border, and result in poor functional and cosmetic results. We decided against primary closure, even with careful attention to reapproximation of the vermilion border, because the width of the defect would have required a large Burow triangle that extended into the oral cavity. For defects less than one-third the width of the lip, full-thickness wedge repair can yield excellent cosmetic results but, in this case, would decrease the oral aperture and was deemed too extensive a procedure for a relatively shallow defect.²

Instead, we chose to perform repair with V to Y advancement of skin below the cutaneous defect, up to the location of the absent vermilion border, combined with small, horizontal, linear closure of the mucosal portion of the defect. This approach is a variation of a repair described by Jin et al,³ who described using 2 opposing V-Y advancement flaps to repair defects of the lip. This repair has provided excellent cosmetic results for a small series of our patients, preserving the oral aperture and maintaining the important aesthetic location of the vermilion border. In addition, the technique makes it unnecessary for the patient to undergo a much larger repair, such as a full- or partial-thickness wedge when the initial defect is relatively shallow.

Closure Technique

It is essential to properly outline the vermilion border of the lip before initiating the repair, ideally before any infiltration of local anesthesia if the surgeon anticipates that tumor extirpation might cross the vermilion border.

Repair
Closing then proceeds as follows:

• The cutaneous portion of the defect is drawn out in standard V to Y fashion, carrying the incision through the dermis and into subcutaneous tissue. The pedicle of the flap is maintained at the base of the island, serving as the blood supply to the flap.

• The periphery of the flap and surrounding tissue is undermined to facilitate movement superiorly into the cutaneous portion of the defect.

• A single buried vertical mattress suture can be placed at the advancing border of the island, holding it in place at the anticipated location of the vermilion border. The secondary defect created by the advancing V is closed to help push the island into place and prevent downward tension on the free margin of the lip.

• The remaining defect of the vermilion lip is closed by removing Burow triangles at the horizontal edges on each side of the remaining defect (Figure, B). The triangles are removed completely within the mucosal lip, with the inferior edge of the triangle placed at the vermilion border.

• The defect is closed in a primary linear horizontal fashion, using buried vertical mattress sutures and cutaneous approximation.

The final appearance of the sutured defect yields a small lateral extension at the superior edge of the V to Y closure, giving the appearance of wings on the Y, prompting us to term the closure V-to-flying-Y (Figure, C).

Although the limited portion of the mucosal lip that is closed in this fashion might appear thinner than the remaining lip, it generally yields a cosmetically acceptable result in the properly selected patient. Our experience also has shown an improvement in this difference in the months following repair. A full mucosal advancement flap might result in a more uniform appearance of the lower lip, but it is a larger and more difficult procedure for the patient to endure. Additionally, a full mucosal advancement flap risks uniformly creating a much thinner lip.

Postoperative Course
Sutures were removed 1 week postoperatively. Proper location of the vermilion border, without distortion of the free margin, was demonstrated. At 11-month follow-up, excellent cosmetic and functional results were noted (Figure, D).

Practice Implications

This repair (1) demonstrates an elegant method of closing a relatively shallow defect that crosses the vermilion border and (2) allows the surgeon to address each cosmetic subunit individually. We have found that this repair provides excellent cosmetic and functional results, with little morbidity.

The lip is a common site of nonmelanoma squamous cell carcinoma. Poorly planned closing after excision of the tumor risks notable impairment of function or cosmetic distortion. When a defect of the lip crosses cosmetic subunits, it is helpful to repair each subunit individually. V-to-flying-Y closure is an effective method to close defects that cross the vermilion border, resulting in well-preserved cosmetic appearance and function.

Intentional tanning—through sun exposure and tanning beds—is an easily avoidable contributor to skin cancer development and an important area for public education. Since the advent of social media, a correlation between social media use and increased indoor tanning behaviors has been reported.¹ In 2010, 11.3% of US adults aged 18 to 29 years reported using a tanning bed in the last 12 months.² The American Academy of Dermatology first published their “Position Statement on Indoor Tanning” in 1998, endorsing a ban on the sale of indoor tanning equipment for nonmedical purposes.³

Although there has been no outright ban on indoor tanning, regulations have been put in place in many states—including Texas, where (as of 2013) a person younger than 18 years must have written consent from their parent(s) to use a tanning bed. Despite efforts of organizations including the American Academy of Dermatology and the government to educate the public on skin cancer prevention and sun safety, the skin cancer rate has been steadily increasing over the last 20 years.

There is a constant campaign among dermatologists to educate their patients on how to reduce or avoid the risk for skin cancer, including the use of sunscreen and avoidance of tanning. Adolescents and young adults are an especially important demographic to reach and educate because increased UV light exposure during these years leads to a greatly increased risk for skin cancer later in life.⁴ Data on the overall prevalence of tanning and the demographics of participation in tanning activities are important to capture and can be used to efficiently target higher-risk populations.

In this study, we aimed to investigate the attitudes and behaviors of adolescents and young adults regarding sun protection and tanning. We also aimed to determine which avenues, including social media, would be most effective at educating about skin cancer awareness and sun protection to the higher-risk younger population.

Materials and Methods

We developed an institutional review board–approved protocol for the prospective collection of data from registered patients at the dermatology clinic of the Mays Cancer Center at the University of Texas Health at San Antonio. A paper survey containing 15 rating-scale questions was administered to 60 patients aged 13 to 27 years. Surveys were administered during intake, prior to the patients’ visit with a dermatologist; all visits were of a functional (not cosmetic) nature. Data collection spanned June to August 2018. Survey results were entered into Research Electronic Data Capture (REDCap) software for qualitative analysis.

Results

Sixty patients responded to the survey. The mean age of respondents was 19.5 years. No surveys were excluded from the data set. Table 1 provides baseline characteristics of respondents. Some respondents left questions unanswered, resulting in questions with fewer than 60 responses.

Among respondents to the survey, 70% (42/60) reported it is very important to protect their skin from sun exposure, and 30% (18/60) reported it is somewhat important. Regarding sunscreen use, 70% (42/60) indicated they use sunscreen only before outdoor activities, 12% (7/60) use sunscreen daily, and 17% (10/60) never use sunscreen. Of those who use sunscreen, 52% (28/54) do so to prevent skin damage and aging and 44% (24/54) to prevent skin cancer. Twenty-three percent (13/56) of respondents reported finding tanned skin attractive; 26% (14/55) reported wanting to be tan. Looking at race, 28% (10/36) of Whites, 25% (5/20) of Spanish/Hispanic/Latinos, and 22% (2/9) of Asians found tanned skin attractive; no Black respondents found tanned skin attractive.

Regarding tanning, 12% (7/57) reported using a tanning bed in their lifetime and 4% (2/57) in the last year; 34% (19/56) reported deliberately tanning outdoors; and 9% (5/56) reported using sunless or spray-on tanning. Dermatologists (75% [42/56]), primary care physicians (69.6% [39/56]), and parents (46.4% [26/56]) were perceived as more effective sources of skin care education; among media modalities, television (33.9% [19/56]), Instagram (30.4% [17/60]), and YouTube (23.2% [13/60]) were perceived as more effective sources of skin care education (Table 2).

Comment

Perceptions of Tanning
Almost one-quarter of respondents found tanned skin attractive, which might reflect a shift from prior generations. Compared to the 11% of respondents in the 2010 survey,² only 3.5% (2/57) of our respondents reported using a tanning bed in the last year, which could reflect the results of recent Texas legislation restricting the use of tanning beds by adolescents.

An alarming number of respondents reported going outdoors with the intention of tanning; although it appears that indoor tanning education has been successful, this finding shows that there is still a need for sun protection education because outdoor tanning is not a suitable alternative. A small number of respondents reported getting a sunless or spray-on tan, which is a risk-free alternative to indoor tanning.

Despite all respondents stating that protecting skin from the sun is important, most respondents surveyed do not use sunscreen daily. More respondents use sunscreen to prevent damage and aging than to prevent skin cancer. Young people might be more alarmed by the threat of early aging and losing their “youthful appearance” than by the possibility of developing skin cancer in the distant future. This discrepancy might indicate a lack of knowledge and be an important focus for future education efforts.

Perceptions of Trustworthiness of Education Sources
Our findings show dermatologists and primary care physicians are important educators on skin protection. Primary care physicians should remain vigilant to recognize at-risk patients who would benefit from skin protection education, especially those who do not see a dermatologist. Education of young people focusing on their concern over maintaining a youthful appearance instead of the possibility of developing skin cancer in the future might be more effective.

Although education provided by a physician is effective, using media—particularly social media—might be more efficient. Television, Instagram, and YouTube were listed by respondents as the 3 most preferred media outlets for skin health education, which shows important areas of focus for future advertising. Facebook was listed at a surprisingly low level, possibly showing the change in use of certain social media websites among this age group. According to the Pew Research Center, the most widely used social media apps among young adults aged 18 to 29 years are YouTube (91%), Facebook (63%), Instagram (67%), and Snapchat (62%). More than half of the same demographic visit Facebook (74%), Instagram (63%), Snapchat (61%), and YouTube (51%) daily.⁵ Although respondents to our survey were not specifically asked about the frequency of their use of social media and our data set includes patients younger than 18 years, we know that social media use has been increasing over the last decade among adolescents.¹ Therefore, we assume that more than one-half of respondents to our survey use their reported social media platforms daily.

Social media is an underused medium for skin cancer prevention education and can reach those who do not regularly see a dermatologist. Unlike printed pamphlets and posters, advertisements through social media can use metrics such as age, race, gender, and interests to target high-risk individuals.

Study Limitations
This was a single-site study of currently enrolled dermatology patients who might be more aware of skin protection than the general population because they are being treated by a dermatologist. Survey questions regarding demographics, required by our institution, could not effectively differentiate Hispanic and White patients. Respondents could have been subject to the Hawthorne effect—awareness that their behavior is being observed—when responding to the survey because it was administered in the office prior to being seen by a dermatologist.

Intentional tanning—through sun exposure and tanning beds—is an easily avoidable contributor to skin cancer development and an important area for public education. Since the advent of social media, a correlation between social media use and increased indoor tanning behaviors has been reported.¹ In 2010, 11.3% of US adults aged 18 to 29 years reported using a tanning bed in the last 12 months.² The American Academy of Dermatology first published their “Position Statement on Indoor Tanning” in 1998, endorsing a ban on the sale of indoor tanning equipment for nonmedical purposes.³

Although there has been no outright ban on indoor tanning, regulations have been put in place in many states—including Texas, where (as of 2013) a person younger than 18 years must have written consent from their parent(s) to use a tanning bed. Despite efforts of organizations including the American Academy of Dermatology and the government to educate the public on skin cancer prevention and sun safety, the skin cancer rate has been steadily increasing over the last 20 years.

There is a constant campaign among dermatologists to educate their patients on how to reduce or avoid the risk for skin cancer, including the use of sunscreen and avoidance of tanning. Adolescents and young adults are an especially important demographic to reach and educate because increased UV light exposure during these years leads to a greatly increased risk for skin cancer later in life.⁴ Data on the overall prevalence of tanning and the demographics of participation in tanning activities are important to capture and can be used to efficiently target higher-risk populations.

In this study, we aimed to investigate the attitudes and behaviors of adolescents and young adults regarding sun protection and tanning. We also aimed to determine which avenues, including social media, would be most effective at educating about skin cancer awareness and sun protection to the higher-risk younger population.

Materials and Methods

We developed an institutional review board–approved protocol for the prospective collection of data from registered patients at the dermatology clinic of the Mays Cancer Center at the University of Texas Health at San Antonio. A paper survey containing 15 rating-scale questions was administered to 60 patients aged 13 to 27 years. Surveys were administered during intake, prior to the patients’ visit with a dermatologist; all visits were of a functional (not cosmetic) nature. Data collection spanned June to August 2018. Survey results were entered into Research Electronic Data Capture (REDCap) software for qualitative analysis.

Results

Sixty patients responded to the survey. The mean age of respondents was 19.5 years. No surveys were excluded from the data set. Table 1 provides baseline characteristics of respondents. Some respondents left questions unanswered, resulting in questions with fewer than 60 responses.

Among respondents to the survey, 70% (42/60) reported it is very important to protect their skin from sun exposure, and 30% (18/60) reported it is somewhat important. Regarding sunscreen use, 70% (42/60) indicated they use sunscreen only before outdoor activities, 12% (7/60) use sunscreen daily, and 17% (10/60) never use sunscreen. Of those who use sunscreen, 52% (28/54) do so to prevent skin damage and aging and 44% (24/54) to prevent skin cancer. Twenty-three percent (13/56) of respondents reported finding tanned skin attractive; 26% (14/55) reported wanting to be tan. Looking at race, 28% (10/36) of Whites, 25% (5/20) of Spanish/Hispanic/Latinos, and 22% (2/9) of Asians found tanned skin attractive; no Black respondents found tanned skin attractive.

Regarding tanning, 12% (7/57) reported using a tanning bed in their lifetime and 4% (2/57) in the last year; 34% (19/56) reported deliberately tanning outdoors; and 9% (5/56) reported using sunless or spray-on tanning. Dermatologists (75% [42/56]), primary care physicians (69.6% [39/56]), and parents (46.4% [26/56]) were perceived as more effective sources of skin care education; among media modalities, television (33.9% [19/56]), Instagram (30.4% [17/60]), and YouTube (23.2% [13/60]) were perceived as more effective sources of skin care education (Table 2).

Comment

Perceptions of Tanning
Almost one-quarter of respondents found tanned skin attractive, which might reflect a shift from prior generations. Compared to the 11% of respondents in the 2010 survey,² only 3.5% (2/57) of our respondents reported using a tanning bed in the last year, which could reflect the results of recent Texas legislation restricting the use of tanning beds by adolescents.

An alarming number of respondents reported going outdoors with the intention of tanning; although it appears that indoor tanning education has been successful, this finding shows that there is still a need for sun protection education because outdoor tanning is not a suitable alternative. A small number of respondents reported getting a sunless or spray-on tan, which is a risk-free alternative to indoor tanning.

Despite all respondents stating that protecting skin from the sun is important, most respondents surveyed do not use sunscreen daily. More respondents use sunscreen to prevent damage and aging than to prevent skin cancer. Young people might be more alarmed by the threat of early aging and losing their “youthful appearance” than by the possibility of developing skin cancer in the distant future. This discrepancy might indicate a lack of knowledge and be an important focus for future education efforts.

Perceptions of Trustworthiness of Education Sources
Our findings show dermatologists and primary care physicians are important educators on skin protection. Primary care physicians should remain vigilant to recognize at-risk patients who would benefit from skin protection education, especially those who do not see a dermatologist. Education of young people focusing on their concern over maintaining a youthful appearance instead of the possibility of developing skin cancer in the future might be more effective.

Although education provided by a physician is effective, using media—particularly social media—might be more efficient. Television, Instagram, and YouTube were listed by respondents as the 3 most preferred media outlets for skin health education, which shows important areas of focus for future advertising. Facebook was listed at a surprisingly low level, possibly showing the change in use of certain social media websites among this age group.

Mohs micrographic surgery (MMS) entails multiple time-consuming surgical and histological examinations for each patient. As surgical stages are performed and histological sections are processed, an efficient communication method among providers, medical assistants, histotechnologists, and patients is necessary to avoid delays. To address these and other communication issues, providers have focused on ways to increase clinic efficiency and improve patient-reported outcomes by utilizing new or repurposed communication technologies in their Mohs practice. 

Prior reports have highlighted the utility of hands-free headsets that allow real-time communication among staff members as a means of increasing clinic efficiency and decreasing patient wait times.^1-4 These systems may mediate a more rapid turnover between stages by mitigating the need for surgeons and support staff to assemble within a designated workspace.^1,3,4 However, there is no single or standardized communication method that best suits all surgical suites and MMS practices. Our study aimed to identify the current communication strategies employed by Mohs surgeons and thereby ascertain which method(s) portend(s) the highest benefit in average daily time savings and provider-perceived patient satisfaction.

Materials and Methods

Survey Instrument
A new 10-question electronic survey was published on the SurveyMonkey website, and a link to the survey was provided in a quarterly email that originated from the American College of Mohs Surgery and was distributed to all 1735 active members. Responses were obtained from January 2019 to February 2019.

Statistical Analysis
A statistical analysis was done to determine any significant associations among the providers’ responses. P<.05 was used to determine statistical significance. A Cochran-Armitage test for trend was used to identify significant associations between the number of rooms and the communication systems that were used. Thus, 7 total tests—1 for each device (whiteboard, light system, flag system, wired intercom, wireless intercom, walkie-talkie, or headset)—were conducted. The Cochran-Armitage test also was used to determine whether the probability of using the device was affected by the number of stations/surgical rooms that were attended by the Mohs surgeons. To determine whether the communication devices used were associated with higher patient satisfaction, a χ² test was conducted for each device (7 total tests), testing the categories of using that device (yes/no) and patient satisfaction (yes/no). A Fisher exact test of independence was used in any case where the proportion for the device and patient satisfaction was 25% or higher. To determine whether the communication method was associated with increased time savings, 7 total Cochran-Armitage tests were conducted, 1 for each device. A logistic regression model was used to determine whether there was a significant association between the number of stations and the likelihood of reporting patient satisfaction.

Results

Eighty-eight surgeons responded to the survey, with a response rate of 5% (88/1735). A total of 55 surgeons completed the survey in its entirety and were included in the data analysis. The most commonly used communication mediums were whiteboards (29/55 [53%]), followed by a flag system (16/55 [29%]) and a light system (13/55 [24%]). Most Mohs surgeons (52/55 [95%]) used the communication media to communicate with their staff only, and 76% (42/55) of Mohs surgeons believed that their communication media contributed to higher patient satisfaction. Overall, 58% (32/55) of Mohs surgeons stated that their communication media saved more than 15 minutes (on average) per day. The use of a whiteboard and/or flag system was reported as the least efficient method, with average daily time savings of 13 minutes. With the introduction of newer technology (wired or wireless intercoms, headsets, walkie-talkies, or internal messaging systems such as Skype) to the whiteboard and/or flag system, the time savings increased by 10 minutes per day. Nearly 25% (14/55) of surgeons utilized more than 1 communication system.

As the number of stations in an MMS suite increased, the probability of using a whiteboard to track the progress of the cases decreased. There were no statistically significant associations identified between the number of stations and the use of other communication devices (ie, flag system, light system, wireless intercom, wired intercom, walkie-talkie, headset). The stratified percentages of the amount of time savings for each communication modality are presented in the Figure (whiteboards and headsets were excluded because they did not increase time savings). The use of a light system was the only communication modality found to be statistically associated with an increase in provider-reported time savings (P=.0482; Figure). In addition, our analysis did not show an improvement in provider-reported patient satisfaction with any of the current systems used in MMS clinics.

Comment

The process of transmitting information among the medical team during MMS is a complex interplay involving the relay of crucial information, with many opportunities for the introduction of distraction and error. Despite numerous improvements in the efficiency of the preparation of histological specimens and implementation of various time-saving and tissue-saving surgical interventions, relatively little attention has been given to address the sometimes chaotic and challenging process of organizing results from each stage of multiple patients in an MMS surgical suite.⁵

As demonstrated by our survey, incorporation of a light-based system into an MMS clinic may improve workplace efficiency by decreasing the redundant use of support staff and allowing Mohs surgeons to transition from one station to the next seamlessly. Light-based communication systems provide an immediate notification for support staff via color-coded and/or numerically coded indicators on input switches located outside and inside the examination/surgery rooms. The switch indicators can be depressed with minimal disruption from station to station, thereby foregoing the need to interrupt an ongoing excision or closure to convey the status of the case. These systems may then permit enhanced clinic and workflow efficiency, which may help to shorten patient wait times.

Conclusion

Our study supports the use of light-based communication systems in MMS suites to improve efficiency in the clinic. Based on our analysis, light-based communication methods were significantly associated with improved time savings (P=.0482). Our study did not show an improvement in provider-reported satisfaction with any of the current systems used in MMS clinics. We hope that this information will help guide providers in implementing new communication techniques to improve clinic efficiency.

The switch indicators can be depressed with minimal disruption from station to station, thereby foregoing the need to interrupt an ongoing excision or closure to convey the status of the case. These systems may then permit enhanced clinic and workflow efficiency, which may help to shorten patient wait times.

Conclusion

Our study supports the use of light-based communication systems in MMS suites to improve efficiency in the clinic. Based on our analysis, light-based communication methods were significantly associated with improved time savings (P=.0482). Our study did not show an improvement in provider-reported satisfaction with any of the current systems used in MMS clinics. We hope that this information will help guide providers in implementing new communication techniques to improve clinic efficiency.

To the Editor:

Melanocytic nevi are ubiquitous, and although they are benign, patients often desire to have them removed. We report a patient who presented to our clinic after attempting home removal of a concerning mole on the back with frankincense, a remedy that she found online.

A 43-year-old woman presented with a worrisome mole on the back. She had no personal history of skin cancer, but her father had a history of melanoma in situ in his 60s. The patient reported that she had the mole for years, but approximately 1 month prior to her visit she noticed that it began to bleed and crust, causing concern for melanoma. She read online that the lesion could be removed with topical application of the essential oil frankincense; she applied it directly to the lesion on the back. Within hours she developed a burn where it was applied with associated blistering.

Clinically, the lesion appeared as a darkly pigmented, well-circumscribed papule with hemorrhagic crust overlying a well-demarcated pink plaque (Figure 1). Dermatoscopically, the lesion lacked a pigment network and demonstrated 2 distinct pink papules with peripheral telangiectasia and a pink background with white streaks (Figure 2). A shave biopsy of the lesion demonstrated a nodular basal cell carcinoma extending to the base and margin.

Approximately 6 million individuals in the United States search the internet for health information daily, and as many as 41% of those do so to learn about alternative medicine.^5,6 Although information gleaned from search engines can be useful, it is unregulated and often can be inaccurate. Clinicians generally are unaware of the erroneous material presented online and, therefore, cannot appropriately combat patient misinformation. Our case demonstrates the need to maintain an awareness of common online fallacies to better answer patient questions and guide them to more accurate sources of dermatologic information and appropriate treatment.

In the analysis of images for detecting potential pathology, artificial intelligence (AI) is showing enormous promise across multiple fields of medicine. But the technology in dermatology is bound to fail in skin of color if training does not specifically address these skin types, according to Adewole S. Adamson, MD, who outlined this issue at the American Academy of Dermatology Virtual Meeting Experience.

“Machine learning algorithms are only as good as the inputs through which they learn. Without representation from individuals with skin of color, we are at risk of creating a new source of racial disparity in patient care,” Dr. Adamson, assistant professor in the division of dermatology, department of internal medicine, University of Texas at Austin, said at the meeting.

Diagnostic algorithms using AI are typically based on deep learning, a subset of machine learning that depends on artificial neural networks. In the case of image processing, neural networks can “learn” to recognize objects, faces, or, in the realm of health care, disease, from exposure to multiple images.

There are many other variables that affect the accuracy of deep learning for diagnostic algorithms, including the depth of the layering through which the process distills multiple inputs of information, but the number of inputs is critical. In the case of skin lesions, machines cannot learn to recognize features of different skin types without exposure.

“There are studies demonstrating that dermatologists can be outperformed for detection of skin cancers by AI, so this is going to be an increasingly powerful tool,” Dr. Adamson said. The problem is that “there has been very little representation in darker skin types” in the algorithms developed so far.

The risk is that AI will exacerbate an existing problem. Skin cancer in darker skin is less common but already underdiagnosed, independent of AI. Per 100,000 males in the United States, the rate of melanoma is about 30-fold greater in White men than in Black men (33.0 vs. 1.0). Among females, the racial difference is smaller but still enormous (20.2 vs. 1.2 per 100,000 females), according to U.S. data.

For the low representation of darker skin in studies so far with AI, “one of the arguments is that skin cancer is not a big deal in darker skin types,” Dr. Adamson said.

It might be the other way around. The relative infrequency with which skin cancer occurs in the Black population in the United States might explain a low level of suspicion and ultimately delays in diagnosis, which, in turn, leads to worse outcomes. According to one analysis drawn from the Surveillance, Epidemiology and End-Result (SEER) database (1998-2011), the proportion of patients with regionally advanced or distant disease was nearly twice as great (11.6% vs. 6.0%; P < .05) in Black patients, relative to White patients.

Not surprisingly, given the importance of early diagnosis of cancers overall and skin cancer specifically, the mean survival for malignant melanoma in Black patients was almost 4 years lower than in White patients (10.8 vs. 14.6 years; P < .001) for nodular melanoma, the same study found.

In humans, bias is reasonably attributed in many cases to judgments made on a small sample size. The problem in AI is analogous. Dr. Adamson, who has published research on the potential for machine learning to contribute to health care disparities in dermatology, cited work done by Joy Buolamwini, a graduate researcher in the media lab at the Massachusetts Institute of Technology. In one study she conducted, the rate of AI facial recognition failure was 1% in White males, 7% in White females, 12% in skin-of-color males, and 35% in skin-of-color females. Fewer inputs of skin of color is the likely explanation, Dr. Adamson said.

The potential for racial bias from AI in the diagnosis of disease increases and becomes more complex when inputs beyond imaging, such as past medical history, are included. Dr. Adamson warned of the potential for “bias to creep in” when there is failure to account for societal, cultural, or other differences that distinguish one patient group from another. However, for skin cancer or other diseases based on images alone, he said there are solutions.

“We are in the early days, and there is time to change this,” Dr. Adamson said, referring to the low representation of skin of color in AI training sets. In addition to including more skin types to train recognition, creating AI algorithms specifically for dark skin is another potential approach.

However, his key point was the importance of recognizing the need for solutions.

“AI is the future, but we must apply the same rigor to AI as to other medical interventions to ensure that the technology is not applied in a biased fashion,” he said.

Susan M. Swetter, MD, professor of dermatology and director of the pigmented lesion and melanoma program at Stanford (Calif.) University Medical Center and Cancer Institute, agreed. As someone who has been following the progress of AI in the diagnosis of skin cancer, Dr. Swetter recognizes the potential for this technology to increase diagnostic efficiency and accuracy, but she also called for studies specific to skin of color.

Sharing their personal experiences on social media can emphasize oncologists’ humanity and have substantive, beneficial effects on patient care, according to a presentation at the Collaboration for Outcomes using Social Media in Oncology (COSMO) inaugural meeting.

Mark A. Lewis, MD, explained to the COSMO meeting audience how storytelling on social media can educate and engage patients, advocates, and professional colleagues – advancing knowledge, dispelling misinformation, and promoting clinical research.

Dr. Lewis, an oncologist at Intermountain Healthcare in Salt Lake City, reflected on the bifid roles of oncologists as scientists engaged in life-long learning and humanists who can internalize and appreciate the unique character and circumstances of their patients.

Patients who have serious illnesses are necessarily aggregated by statistics. However, in an essay published in 2011, Dr. Lewis noted that “each individual patient partakes in a unique, irreproducible experiment where n = 1” (J Clin Oncol. 2011 Aug 1;29[22]:3103-4).

Dr. Lewis highlighted the duality of individual data points on a survival curve as descriptors of common disease trajectories and treatment effects. However, those data points also conceal important narratives regarding the most highly valued aspects of the doctor-patient relationship and the impact of cancer treatment on patients’ lives.

In referring to the futuristic essay “Ars Brevis,” Dr. Lewis contrasted the humanism of oncology specialists in the present day with the fictional image of data-regurgitating robots programmed to maximize the efficiency of each patient encounter (J Clin Oncol. 2013 May 10;31[14]:1792-4).

Dr. Lewis reminded attendees that to practice medicine without using both “head and heart” undermines the inherent nature of medical care.

Unfortunately, that perspective may not match the public perception of oncologists. Dr. Lewis described his experience of typing “oncologists are” into an Internet search engine and seeing the auto-complete function prompt words such as “criminals,” “evil,” “murderers,” and “confused.”

Obviously, it is hard to establish a trusting patient-doctor relationship if that is the prima facie perception of the oncology specialty.
 

Dispelling myths and creating community via social media

A primary goal of consultation with a newly-diagnosed cancer patient is for the patient to feel that the oncologist will be there to take care of them, regardless of what the future holds.

Dr. Lewis has found that social media can potentially extend that feeling to a global community of patients, caregivers, and others seeking information relevant to a cancer diagnosis. He believes that oncologists have an opportunity to dispel myths and fears by being attentive to the real-life concerns of patients.

Dr. Lewis took advantage of this opportunity when he underwent a Whipple procedure (pancreaticoduodenectomy) for a pancreatic neuroendocrine tumor. He and the hospital’s media services staff “live-tweeted” his surgery and recovery.

With those tweets, Dr. Lewis demystified each step of a major surgical procedure. From messages he received on social media, Dr. Lewis knows he made the decision to have a Whipple procedure more acceptable to other patients.

His personal medical experience notwithstanding, Dr. Lewis acknowledged that every patient’s circumstances are unique.

Oncologists cannot possibly empathize with every circumstance. However, when they show sensitivity to personal elements of the cancer experience, they shed light on the complicated role they play in patient care and can facilitate good decision-making among patients across the globe.
 

Social media for professional development and patient care

The publication of his 2011 essay was gratifying for Dr. Lewis, but the finite number of comments he received thereafter illustrated the rather limited audience that traditional academic publications have and the laborious process for subsequent interaction (J Clin Oncol. 2011 Aug 1;29[22]:3103-4).

First as an observer and later as a participant on social media, Dr. Lewis appreciated that teaching points and publications can be amplified by global distribution and the potential for informal bidirectional communication.

Social media platforms enable physicians to connect with a larger audience through participative communication, in which users develop, share, and react to content (N Engl J Med. 2009 Aug 13;361[7]:649-51).

Dr. Lewis reflected on how oncologists are challenged to sort through the thousands of oncology-focused publications annually. Through social media, one can see the studies on which the experts are commenting and appreciate the nuances that contextualize the results. Focused interactions with renowned doctors, at regular intervals, require little formality.

Online journal clubs enable the sharing of ideas, opinions, multimedia resources, and references across institutional and international borders (J Gen Intern Med. 2014 Oct;29[10]:1317-8).
 

Social media in oncology: Accomplishments and promise

The development of broadband Internet, wireless connectivity, and social media for peer-to-peer and general communication are among the major technological advances that have transformed medical communication.

As an organization, COSMO aims to describe, understand, and improve the use of social media to increase the penetration of evidence-based guidelines and research insights into clinical practice (Future Oncol. 2017 Jun;13[15]:1281-5).

At the inaugural COSMO meeting, areas of progress since COSMO’s inception in 2015 were highlighted, including:

• The involvement of cancer professionals and advocates in multiple distinctive platforms.
• The development of hashtag libraries to aggregate interest groups and topics.
• The refinement of strategies for engaging advocates with attention to inclusiveness.
• A steady trajectory of growth in tweeting at scientific conferences.

An overarching theme of the COSMO meeting was “authenticity,” a virtue that is easy to admire but requires conscious, consistent effort to achieve.

Disclosure of conflicts of interest and avoiding using social media simply as a recruitment tool for clinical trials are basic components of accurate self-representation.

In addition, Dr. Lewis advocated for sharing personal experiences in a component of social media posts so oncologists can show humanity as a feature of their professional online identity and inherent nature.

Dr. Lewis disclosed consultancy with Medscape/WebMD, which are owned by the same parent company as MDedge. He also disclosed relationships with Foundation Medicine, Natera, Exelixis, QED, HalioDX, and Ipsen.


Dr. Lyss was a community-based medical oncologist and clinical researcher for more than 35 years before his recent retirement. His clinical and research interests were focused on breast and lung cancers, as well as expanding clinical trial access to medically underserved populations. He is based in St. Louis. He has no conflicts of interest.

However, those data points also conceal important narratives regarding the most highly valued aspects of the doctor-patient relationship and the impact of cancer treatment on patients’ lives.

In referring to the futuristic essay “Ars Brevis,” Dr. Lewis contrasted the humanism of oncology specialists in the present day with the fictional image of data-regurgitating robots programmed to maximize the efficiency of each patient encounter (J Clin Oncol. 2013 May 10;31[14]:1792-4).

Dr. Lewis reminded attendees that to practice medicine without using both “head and heart” undermines the inherent nature of medical care.

Unfortunately, that perspective may not match the public perception of oncologists. Dr. Lewis described his experience of typing “oncologists are” into an Internet search engine and seeing the auto-complete function prompt words such as “criminals,” “evil,” “murderers,” and “confused.”

Obviously, it is hard to establish a trusting patient-doctor relationship if that is the prima facie perception of the oncology specialty.
 

Dispelling myths and creating community via social media

A primary goal of consultation with a newly-diagnosed cancer patient is for the patient to feel that the oncologist will be there to take care of them, regardless of what the future holds.

Dr. Lewis has found that social media can potentially extend that feeling to a global community of patients, caregivers, and others seeking information relevant to a cancer diagnosis. He believes that oncologists have an opportunity to dispel myths and fears by being attentive to the real-life concerns of patients.

Dr. Lewis took advantage of this opportunity when he underwent a Whipple procedure (pancreaticoduodenectomy) for a pancreatic neuroendocrine tumor. He and the hospital’s media services staff “live-tweeted” his surgery and recovery.

With those tweets, Dr. Lewis demystified each step of a major surgical procedure. From messages he received on social media, Dr. Lewis knows he made the decision to have a Whipple procedure more acceptable to other patients.

His personal medical experience notwithstanding, Dr. Lewis acknowledged that every patient’s circumstances are unique.

Oncologists cannot possibly empathize with every circumstance. However, when they show sensitivity to personal elements of the cancer experience, they shed light on the complicated role they play in patient care and can facilitate good decision-making among patients across the globe.
 

Social media for professional development and patient care

The publication of his 2011 essay was gratifying for Dr. Lewis, but the finite number of comments he received thereafter illustrated the rather limited audience that traditional academic publications have and the laborious process for subsequent interaction (J Clin Oncol. 2011 Aug 1;29[22]:3103-4).

First as an observer and later as a participant on social media, Dr. Lewis appreciated that teaching points and publications can be amplified by global distribution and the potential for informal bidirectional communication.

Social media platforms enable physicians to connect with a larger audience through participative communication, in which users develop, share, and react to content (N Engl J Med. 2009 Aug 13;361[7]:649-51).

Dr. Lewis reflected on how oncologists are challenged to sort through the thousands of oncology-focused publications annually. Through social media, one can see the studies on which the experts are commenting and appreciate the nuances that contextualize the results. Focused interactions with renowned doctors, at regular intervals, require little formality.

Online journal clubs enable the sharing of ideas, opinions, multimedia resources, and references across institutional and international borders (J Gen Intern Med. 2014 Oct;29[10]:1317-8).
 

Social media in oncology: Accomplishments and promise

The development of broadband Internet, wireless connectivity, and social media for peer-to-peer and general communication are among the major technological advances that have transformed medical communication.

As an organization, COSMO aims to describe, understand, and improve the use of social media to increase the penetration of evidence-based guidelines and research insights into clinical practice (Future Oncol. 2017 Jun;13[15]:1281-5).

At the inaugural COSMO meeting, areas of progress since COSMO’s inception in 2015 were highlighted, including:

• The involvement of cancer professionals and advocates in multiple distinctive platforms.
• The development of hashtag libraries to aggregate interest groups and topics.
• The refinement of strategies for engaging advocates with attention to inclusiveness.
• A steady trajectory of growth in tweeting at scientific conferences.

An overarching theme of the COSMO meeting was “authenticity,” a virtue that is easy to admire but requires conscious, consistent effort to achieve.

Disclosure of conflicts of interest and avoiding using social media simply as a recruitment tool for clinical trials are basic components of accurate self-representation.

In addition, Dr. Lewis advocated for sharing personal experiences in a component of social media posts so oncologists can show humanity as a feature of their professional online identity and inherent nature.

Dr. Lewis disclosed consultancy with Medscape/WebMD, which are owned by the same parent company as MDedge. He also disclosed relationships with Foundation Medicine, Natera, Exelixis, QED, HalioDX, and Ipsen.


Dr. Lyss was a community-based medical oncologist and clinical researcher for more than 35 years before his recent retirement. His clinical and research interests were focused on breast and lung cancers, as well as expanding clinical trial access to medically underserved populations. He is based in St. Louis. He has no conflicts of interest.

Immunotherapy with checkpoint inhibitors has ushered in a new era of cancer therapy, with some patients showing dramatic responses and significantly better outcomes than with other therapies across many cancer types. But some patients do worse, sometimes much worse.

A subset of patients who undergo immunotherapy experience unexpected, rapid disease progression, with a dramatic acceleration of disease trajectory. They also have a shorter progression-free survival and overall survival than would have been expected.

This has been described as hyperprogression and has been termed “hyperprogressive disease” (HPD). It has been seen in a variety of cancers; the incidence ranges from 4% to 29% in the studies reported to date.

There has been some debate over whether this is a real phenomenon or whether it is part of the natural course of disease.

HPD is a “provocative phenomenon,” wrote the authors of a recent commentary entitled “Hyperprogression and Immunotherapy: Fact, Fiction, or Alternative Fact?”

“This phenomenon has polarized oncologists who debate that this could still reflect the natural history of the disease,” said the author of another commentary.

But the tide is now turning toward acceptance of HPD, said Kartik Sehgal, MD, an oncologist at Dana-Farber Cancer Institute and Harvard University, both in Boston.

“With publication of multiple clinical reports of different cancer types worldwide, hyperprogression is now accepted by most oncologists to be a true phenomenon rather than natural progression of disease,” Dr. Sehgal said.

He authored an invited commentary in JAMA Network Openabout one of the latest meta-analyses (JAMA Netw Open. 2021;4[3]:e211136) to investigate HPD during immunotherapy. One of the biggest issues is that the studies that have reported on HPD have been retrospective, with a lack of comparator groups and a lack of a standardized definition of hyperprogression. Dr. Sehgal emphasized the need to study hyperprogression in well-designed prospective studies.
 

Existing data on HPD

HPD was described as “a new pattern of progression” seen in patients undergoing immune checkpoint inhibitor therapy in a 2017 article published in Clinical Cancer Research. Authors Stephane Champiat, MD, PhD, of Institut Gustave Roussy, Universite Paris Saclay, Villejuif, France, and colleagues cited “anecdotal occurrences” of HPD among patients in phase 1 trials of anti–PD-1/PD-L1 agents.

In that study, HPD was defined by tumor growth rate ratio. The incidence was 9% among 213 patients.

The findings raised concerns about treating elderly patients with anti–PD-1/PD-L1 monotherapy, according to the authors, who called for further study.

That same year, Roberto Ferrara, MD, and colleagues from the Insitut Gustave Roussy reported additional data indicating an incidence of HPD of 16% among 333 patients with non–small cell lung cancer who underwent immunotherapy at eight centers from 2012 to 2017. The findings, which were presented at the 2017 World Conference on Lung Cancer and reported at the time by this news organization, also showed that the incidence of HPD was higher with immunotherapy than with single-agent chemotherapy (5%).

Median overall survival (OS) was just 3.4 months among those with HPD, compared with 13 months in the overall study population – worse, even, than the median 5.4-month OS observed among patients with progressive disease who received immunotherapy.

In the wake of these findings, numerous researchers have attempted to better define HPD, its incidence, and patient factors associated with developing HPD while undergoing immunotherapy.

However, there is little so far to show for those efforts, Vivek Subbiah, MD, of the University of Texas MD Anderson Cancer Center, Houston, said in an interview.

“Many questions remain to be answered,” said Dr. Subbiah, clinical medical director of the Clinical Center for Targeted Therapy in the division of cancer medicine at MD Anderson. He was the senior author of the “Fact, Fiction, or Alternative Fact?” commentary.

Work is underway to elucidate biological mechanisms. Some groups have implicated the Fc region of antibodies. Another group has reported EGFR and MDM2/MDM4 amplifications in patients with HPD, Dr. Subbiah and colleagues noted.

Other “proposed contributing pathological mechanisms include modulation of tumor immune microenvironment through macrophages and regulatory T cells as well as activation of oncogenic signaling pathways,” noted Dr. Sehgal.

Both groups of authors emphasize the urgent need for prospective studies.

It is imperative to confirm underlying biology, predict which patients are at risk, and identify therapeutic directions for patients who experience HPD, Dr. Subbiah said.

The main challenge is defining HPD, he added. Definitions that have been proposed include tumor growth at least two times greater than in control persons, a 15% increase in tumor burden in a set period, and disease progression of 50% from the first evaluation before treatment, he said.

The recent meta-analysis by Hyo Jung Park, MD, PhD, and colleagues, which Dr. Sehgal addressed in his invited commentary, highlights the many approaches used for defining HPD.

Depending on the definition used, the incidence of HPD across 24 studies involving more than 3,100 patients ranged from 5.9% to 43.1%.

“Hyperprogressive disease could be overestimated or underestimated based on current assessment,” Dr. Park and colleagues concluded. They highlighted the importance of “establishing uniform and clinically relevant criteria based on currently available evidence.”
 

Steps for solving the HPD mystery

“I think we need to come up with consensus criteria for an HPD definition. We need a unified definition,” Dr. Subbiah said. “We also need to design prospective studies to prove or disprove the immunotherapy-HPD association.”

Prospective registries with independent review of patients with suspected immunotherapy-related HPD would be useful for assessing the true incidence and the biology of HPD among patients undergoing immunotherapy, he suggested.

“We need to know the immunologic signals of HPD. This can give us an idea if patients can be prospectively identified for being at risk,” he said. “We also need to know what to do if they are at risk.”

Dr. Sehgal also called for consensus on an HPD definition, with input from a multidisciplinary group that includes “colleagues from radiology, medical oncology, radiation oncology. Getting expertise from different disciplines would be helpful,” he said.

Dr. Park and colleagues suggested several key requirements for an optimal HP definition, such as the inclusion of multiple variables for measuring tumor growth acceleration, “sufficiently quantitative” criteria for determining time to failure, and establishment of a standardized measure of tumor growth acceleration.

The agreed-upon definition of HPD could be applied to patients in a prospective registry and to existing trial data, Dr. Sehgal said.

“Eventually, the goal of this exercise is to [determine] how we can help our patients the best, having a biomarker that can at least inform us in terms of being aware and being proactive in terms of looking for this ... so that interventions can be brought on earlier,” he said.

“If we know what may be a biological mechanism, we can design trials that are designed to look at how to overcome that HPD,” he said.

Dr. Sehgal said he believes HPD is triggered in some way by treatment, including immunotherapy, chemotherapy, and targeted therapy, but perhaps in different ways for each.

He estimated the true incidence of immunotherapy-related HPD will be in the 9%-10% range.

“This is a substantial number of patients, so it’s important that we try to understand this phenomenon, using, again, uniform criteria,” he said.
 

Current treatment decision-making

Until more is known, Dr. Sehgal said he considers the potential risk factors when treating patients with immunotherapy.

For example, the presence of MDM2 or MDM4 amplification on a genomic profile may factor into his treatment decision-making when it comes to using immunotherapy or immunotherapy in combination with chemotherapy, he said.

“Is that the only factor that is going to make me choose one thing or another? No,” Dr. Sehgal said. However, he said it would make him more “proactive in making sure the patient is doing clinically okay” and in determining when to obtain on-treatment imaging studies.

Dr. Subbiah emphasized the relative benefit of immunotherapy, noting that survival with chemotherapy for many difficult-to-treat cancers in the relapsed/refractory metastatic setting is less than 2 years.

Immunotherapy with checkpoint inhibitors has allowed some of these patients to live longer (with survival reported to be more than 10 years for patients with metastatic melanoma).

“Immunotherapy has been a game changer; it has been transformative in the lives of these patients,” Dr. Subbiah said. “So unless there is any other contraindication, the benefit of receiving immunotherapy for an approved indication far outweighs the risk of HPD.”

Dermatologists cautioned colleagues to be aware of special hazards facing the LGBTQ community: A higher risk of skin cancer among gay men, possibly because of excess ultraviolet exposure, and acne in transgender people, who are especially vulnerable to acne because of hormone therapy.

The identities of sexual minorities “have a significant influence on many facets of health,” dermatologist Matthew Mansh, MD, of the University of Minnesota, Minneapolis, said in a presentation at the American Academy of Dermatology Virtual Meeting Experience.

In regard to skin cancer, he said, “there seems to be consistently higher rates of skin cancer and certain preventable risk behaviors like indoor tanning among sexual minority men.”

Dr. Mansh, codirector of the high-risk nonmelanoma skin cancer clinic at the University of Minnesota, highlighted a report, published in JAMA Dermatology in 2020, that used 2014-2018 U.S. survey data of over 870,000 adults to look at the association between sexual orientation and lifetime prevalence of skin cancer. The investigators found that gay and bisexual men had a higher lifetime prevalence of skin cancer compared with heterosexual men (adjusted odds ratio [aOR], 1.25; 95% confidence interval, 1.03-1.50; P = .02; and aOR, 1.46; 95% CI, 1.01-2.10; P = .04; for gay and bisexual men, respectively).

When compared with heterosexual women, risk among bisexual women was lower (aOR, 0.75; 95% CI, 0.60-0.95; P  = .02), but not among lesbian women (aOR, 1.01; 95% CI, 0.77-1.33; P = .95, respectively).

Other studies have reached similar conclusions, Dr. Mansh said, although there’s been fairly little research in this area. What could explain these differences? Factors such as smoking, age, and alcohol use affect skin cancer risk, he said, but these studies control for those variables. Instead, he noted, it’s useful to look at studies of ultraviolet exposure.

For example, he highlighted a study published in JAMA Dermatology in 2015, which examined 12-month indoor-tanning rates and skin cancer prevalence by sexual orientation, using data from California and national health interview surveys. The study found that compared with heterosexual men, “sexual minority men had higher rates of indoor tanning by roughly three- to sixfold,” said Dr. Mansh, the lead author. “And this was among respondents who were adults over age 18. People between the ages of 18 and 34 years are important from a skin cancer perspective as it’s well established that exposure to tanning beds at a younger age is most associated with an increased risk of skin cancer.”

Sexual minority men were also significantly more likely to report having skin cancer, compared with heterosexual men.

In the study, sexual minority women had about half the odds of engaging in indoor tanning compared with heterosexual women, and were less likely to report having been diagnosed with nonmelanoma skin cancer, he added.

Other studies suggest that gay and bisexual men live in neighborhoods with more indoor tanning salons and that they may spend more time in the sun outside too, he said. Some research suggests motivations for tanning include social pressure and the desire to improve appearance, he added.

Overall, “we may be able to use these data to add more appropriate screening and recommendations for these patients, which are sorely lacking in dermatology,” and to design targeted behavioral interventions, said Dr. Mansh, codirector of the dermatology gender care clinic at the University of Minnesota.

What can dermatologists do now? In an interview, dermatologist Jon Klint Peebles, MD, of the mid-Atlantic Permanente Medical Group, in Largo, Md., suggested that colleagues ask patients questions about indoor tanning frequency, the motivations for tanning, exposure to outdoor ultraviolet radiation, sunscreen use, and use of photoprotective clothing.

Hormone therapy and acne

In a related presentation at the meeting, Howa Yeung, MD, of the department of dermatology, Emory University, Atlanta, said that in transgender people, estrogen therapy can actually reduce sebum production and often improves acne, while testosterone therapy frequently has the opposite effect.

“We’ve seen some pretty tough cases of acne in transmasculine patients in my practice,” said Dr. Yeung, who highlighted a recently published study that tracked 988 transgender patients in Boston who underwent testosterone therapy. Nearly a third were diagnosed with acne, compared with 6% prior to hormone therapy, and those at the highest risk were aged 18-21.

The prevalence of acne was 25% 2 years after initiation of hormone therapy. “Acne remains a very common issue and not just at the beginning of treatment,” he said.

In 2020, Dr. Yeung and colleagues reported the results of a survey of 696 transgender patients in California and Georgia; most were treated with hormone therapy. They found that 14% of transmasculine patients reported currently having moderate to severe acne diagnosed by a physician, compared with 1% of transfeminine patients.

Dr. Yeung noted that another survey of transmasculine persons who had received testosterone found that those who had moderate to severe acne were more likely to suffer from depression and anxiety than were those who had never had acne (aOR, 2.4; 95% CI, 1.1-5.4; P = .001, for depression; and aOR, 2.7; 95% CI, 1.2-6.3; P = .002, for anxiety).

Acne treatments in transmasculine patients are complicated by the fact that hormone treatments for acne can have feminizing effects, Dr. Yeung said, adding that it’s not clear how clascoterone, a new anti-androgen topical therapy for acne, will affect them. For now, many patients will require isotretinoin for treating acne.

Dr. Peebles cautioned that with isotretinoin, “we still do not yet have solid data on the optimal dosing or duration in the context of testosterone-induced acne, as well as what individual factors may be predictive of treatment success or failure. It is also important to be aware of any planned surgical procedures, whether as part of gender-affirming care or otherwise, given that some surgeons may view isotretinoin as a barrier for some procedures, despite limited data to support this.”

Both Dr. Peebles and Dr. Yeung noted that the iPledge risk management program for isotretinoin patients who may become pregnant is problematic. “A trans man who is assigned female at birth and identifies as a man and has a uterus and ovaries must be registered as a female with reproductive potential,” Dr. Yeung said.

“While the program remains inherently discriminatory, it is important to have an honest conversation with patients about these issues in a sensitive way,” Dr. Peebles noted. “Luckily, there is substantial momentum building around modifying iPLEDGE to become more inclusive. While the mechanics are complicated and involve a variety of entities and advocacy initiatives, we are optimistic that major changes are in the pipeline.”

Dermatologists cautioned colleagues to be aware of special hazards facing the LGBTQ community: A higher risk of skin cancer among gay men, possibly because of excess ultraviolet exposure, and acne in transgender people, who are especially vulnerable to acne because of hormone therapy.

The identities of sexual minorities “have a significant influence on many facets of health,” dermatologist Matthew Mansh, MD, of the University of Minnesota, Minneapolis, said in a presentation at the American Academy of Dermatology Virtual Meeting Experience.

In regard to skin cancer, he said, “there seems to be consistently higher rates of skin cancer and certain preventable risk behaviors like indoor tanning among sexual minority men.”

Dr. Mansh, codirector of the high-risk nonmelanoma skin cancer clinic at the University of Minnesota, highlighted a report, published in JAMA Dermatology in 2020, that used 2014-2018 U.S. survey data of over 870,000 adults to look at the association between sexual orientation and lifetime prevalence of skin cancer. The investigators found that gay and bisexual men had a higher lifetime prevalence of skin cancer compared with heterosexual men (adjusted odds ratio [aOR], 1.25; 95% confidence interval, 1.03-1.50; P = .02; and aOR, 1.46; 95% CI, 1.01-2.10; P = .04; for gay and bisexual men, respectively).

When compared with heterosexual women, risk among bisexual women was lower (aOR, 0.75; 95% CI, 0.60-0.95; P  = .02), but not among lesbian women (aOR, 1.01; 95% CI, 0.77-1.33; P = .95, respectively).

Other studies have reached similar conclusions, Dr. Mansh said, although there’s been fairly little research in this area. What could explain these differences? Factors such as smoking, age, and alcohol use affect skin cancer risk, he said, but these studies control for those variables. Instead, he noted, it’s useful to look at studies of ultraviolet exposure.

For example, he highlighted a study published in JAMA Dermatology in 2015, which examined 12-month indoor-tanning rates and skin cancer prevalence by sexual orientation, using data from California and national health interview surveys. The study found that compared with heterosexual men, “sexual minority men had higher rates of indoor tanning by roughly three- to sixfold,” said Dr. Mansh, the lead author. “And this was among respondents who were adults over age 18. People between the ages of 18 and 34 years are important from a skin cancer perspective as it’s well established that exposure to tanning beds at a younger age is most associated with an increased risk of skin cancer.”

Sexual minority men were also significantly more likely to report having skin cancer, compared with heterosexual men.

In the study, sexual minority women had about half the odds of engaging in indoor tanning compared with heterosexual women, and were less likely to report having been diagnosed with nonmelanoma skin cancer, he added.

Other studies suggest that gay and bisexual men live in neighborhoods with more indoor tanning salons and that they may spend more time in the sun outside too, he said. Some research suggests motivations for tanning include social pressure and the desire to improve appearance, he added.

Overall, “we may be able to use these data to add more appropriate screening and recommendations for these patients, which are sorely lacking in dermatology,” and to design targeted behavioral interventions, said Dr. Mansh, codirector of the dermatology gender care clinic at the University of Minnesota.

Approximately three-quarters of Mohs surgeons recommended nicotinamide for prevention of keratinocyte carcinoma, in a survey of members of the American College of Mohs Surgeons.

Although nicotinamide, a vitamin B3 derivative, has been shown to reduce keratinocyte carcinoma (KC) in high-risk patients, it is not approved by the Food and Drug Administration for chemoprevention, and no safe upper limit has been established in clinical trials to date, wrote Sheena Desai of Brigham and Women’s Hospital and Harvard Medical School, Boston, and colleagues.

The investigators emailed an anonymous 12-question survey to 1,500 members of the American College of Mohs Surgeons. Of the 170 who responded, 10 were excluded for discordant responses, leaving 160 participants whose replies were included in a multiple logistic regression analysis. The respondents were mainly U.S. board-certified dermatologists and Mohs surgeons (99.4% for both); 86.9% were in clinical practice, including 78.8% in private practice, according to the report of the results, published in Dermatologic Surgery.

Overall, 76.9% of the respondents said they recommended nicotinamide for preventing KC, and 20% said they had recommended nicotinamide to more than 100 patients in the past year. In addition, 45% of respondents reported patients who had been taking nicotinamide for 2 years or more. Overall, 63.8% of the respondents expressed no concerns about long-term safety of nicotinamide, compared with 28.1% who said they were uncertain about long-term safety. Those who expressed concern or uncertainty about long-term safety were significantly less likely to recommend nicotinamide for KC prevention in the past year (odds ratio, 0.30; 95% confidence interval [CI] 0.13-0.71). Clinicians with more than 10 years in practice were significantly less likely to recommend nicotinamide for chemoprevention (OR, 0.20; 95% CI 0.05-0.82).

The study findings were limited by several factors, including the low number of responses and the potential lack of generalizability to clinicians other than Mohs surgeons, the researchers noted. “Additional studies on nicotinamide safety and use patterns, including cost-effectiveness analyses, are needed given the widespread use identified in this study,” they concluded.

Limited safety data highlight research gaps

The study is particularly important at this time because nicotinamide has been increasingly used for KC chemoprevention since a randomized, controlled trial published in 2015 in the New England Journal of Medicine showed benefits, corresponding author Rebecca I. Hartman, MD, of the department of dermatology, Brigham and Women’s Hospital and Harvard University, Boston, said in an interview. That study of high-risk patients found that nicotinamide, 500 mg twice a day, was safe and effective in lowering the rates of new nonmelanoma skin cancers and AKs after 12 months .

“However, because this is not a prescription medication, but rather an OTC vitamin supplement, data on its use are not available,” she said.

Dr. Hartman said she was not surprised that nicotinamide is being used frequently by a majority of the survey respondents. “Most are using this if someone has two KCs over 2 years, which is a quite common occurrence,” she noted. However, “I was a bit surprised that nearly two-thirds had no safety concerns with long-term use, even though this has not been well-studied,” she added.

“Like anything we recommend, we must consider the risks and benefits,” Dr. Hartman said of nicotinamide. “Unfortunately, we don’t know the risks well, since this hasn’t been well-characterized with regular long-term use in these doses,” and more research is needed, she said. “The risks are likely low, as this is a vitamin that has been used for years in various OTC supplements,” she added. “However, there are some data showing slightly increased all-cause mortality with similar doses of a related medicine, niacin, in cardiovascular patients. For this reason, I recommend the medication when a patient’s KCs are really becoming burdensome – several KCs in a year or two – or when they are high-risk due to immunosuppression,” she explained.

“We also must consider the individual patient. For a healthy younger patient who has a public-facing job and as a result is very averse to developing any KCs on his or her face and very motivated to try prevention, it may make sense to try nicotinamide,” Dr. Hartman said. But for an older patient with cardiovascular comorbidities who is not bothered by a KC on his or her back or extremities, “this medication may not have a favorable risk-benefit profile.”

To address safety concerns, “researchers need to examine whether there are any harms in long-term regular nicotinamide use for KC prevention,” Dr. Hartman said. “This is something we hope to do in our patients; however, it is challenging to study in a retrospective way since the harm is likely small and there are so many other features that influence mortality as an outcome,” she noted.

The study received no outside funding. The researchers had no financial conflicts to disclose.
