Racial differences in skin cancer awareness and surveillance practices at a public hospital dermatology clinic

"There is a life before and after cancer": experiences of resuming life and unmet care needs in stage I and II melanoma survivors

Although the largest increase in melanoma incidence is observed for localised melanoma, little research has been done on its impact. Despite favourable prognoses and relatively short treatment trajectories, diagnosis and treatment may significantly impact life post-treatment. Therefore, the aim of this study was to gain an in-depth understanding of stage I and II melanoma survivors' experiences resuming life after treatment and their associated survivorship care (SSC) needs. A qualitative focus group study was conducted with 18 stage I or II melanoma survivors, divided over three focus groups with 6 survivors each. Transcripts were analysed through thorough thematic content analysis, using multiple phases of coding. In resuming life, survivors experienced profound initial impacts of disease and treatment, fed by a perceived lack of knowledge and underestimation of melanoma. They faced unexpected physical and emotional effects post-surgery, experiencing mixed feelings from relief to fear and uncertainty. Survivors felt misunderstood, had to adjust their lives, and managed personal and external expectations while experiencing a positive shift in life perspective, leading to a notable difference in life before and after cancer. In terms of SSC needs, survivors stressed the need for tailored information, accessible resources, patient-centered follow-up, and supportive care addressing the total impact of disease and treatment. These findings highlight the importance of improving melanoma awareness and providing holistic SSC not only to advanced, but also to localised melanoma survivors. A tailored survivorship care plan could facilitate access to information and supportive care, helping patients resume their lives.

Clinicopathologic comparison of basal cell carcinoma among a diverse patient population in Los Angeles County

Introduction

Basal cell carcinoma (BCC) is the most common malignancy in the United States. The majority of cases are identified in Non-Hispanic Whites (NHW) and are far less demonstrated in patients of colour (POC). However, the Hispanic population represents a large and growing proportion of the US population, and skin cancer diagnoses in Hispanics are rising. Thus, the goal of this study is to examine clinicopathologic differences between BCC in Hispanics versus NHW.

Methods

A retrospective chart review of Hispanic and NHW patients with BCC at Los Angeles County + USC Medical Center from January 2018 to March 2020 was performed. In total, 101 BCC samples from the first 100 patients identified of Hispanic ancestry, as well as 50 BCC samples identified from the first 50 patients identifying as NHW, were included for analysis. Patient characteristics (age, sex, medical history, and ethnicity), as well as tumour characteristics (location, subtype, tumour depth, and perineural invasion), were collected. We used between subjects t-tests for continuous variables, and chi-square tests for categorical variables.

Results

In total, 151 specimens were collected amongst 122 subjects (79 Hispanics and 43 NHW patients). Among NHW, the majority of patients (74.4%) were men, but among the Hispanic population, the majority (68.4%) were female (p < 0.001). Prior history of other skin cancer was more common among NHW (67.4%) than Hispanics (31.6%) (p=<0.001). The Hispanic population had a significantly higher proportion of head and neck tumours (p = 0.0004) but a lower proportion of extremity tumours (p = 0.001) compared to NHW. Pigmented BCC was significantly more common among Hispanic patients (p < 0.01). Finally, within the Hispanic group, there was a significant association between sex and histology (p = 0.004), with Hispanic men demonstrating more aggressive mix histology compared to Hispanic women.

Discussion

Our study supports the notion that BCC disparities occur among POC compared to NHW. This includes variations in epidemiologic factors such as sex and past medical history, primary tumour location, and pathologic characteristics. Further research should be conducted to identify additional differences in skin cancer presentation in POC to reduce the gaps in skin cancer knowledge and care.

Sunscreen use and affordability attitudes based on ethnicity, socioeconomic status, and Fitzpatrick skin type

IMPORTANCE

One in five Americans will develop skin cancer during their lifetime. While use of sunscreen can help prevent the development cutaneous cancer, regular use remains low nationwide.

OBJECTIVE

To assess and better understand health care consumer preferences for sun protection products and perceived product accessibility and availability based on socioeconomic factors, race, and ethnicity.

DESIGN

This quantitative survey study was conducted March through June of 2023.

SETTING

Participants were recruited from two university family medicine clinical sites in the Buffalo, New York area, one located in a low and one located in a middle-to-upper socioeconomic neighborhood.

PARTICIPANTS

Eligible participants were 18 years or older, fluent in English, and residents of the Buffalo, New York area. Surveys and consent forms were distributed by scripted verbal invitation, inviting all clinic patients who met eligibility criteria to participate. Participants were asked to self-report their racial/ethnic group as well as other demographic information including age, gender identification, household income, and household size. Information regarding sun exposure behaviors, and affordability/access was obtained using a combination of multiple choice and yes/no questions. A total of 405 participants were recruited. After excluding 235 incomplete responses, 170 surveys were available for analysis.

INTERVENTIONS

None.

MAIN OUTCOMES AND MEASURES

Our study aim was to expose health care consumer preferences as well as barriers to access based on socioeconomic factors, race, and ethnicity.

RESULTS

Using a 25-question anonymous survey, 405 participants from two university family medicine clinical sites representing low- and middle-to-high-income neighborhoods, participated in the survey. 170 participants completed the survey questions and were included for analysis. Of those, 61.8% identified as female, 37.6% as male, and 0.6% as other. 51.2% of participants identified as lower income, 38.2% as middle-income, and 10.6% as upper income. The results of the survey revealed disparities in sunscreen use and affordability perceptions across demographic groups. Compared with Hispanics, Caucasians exhibited higher rates of sunscreen use (85 Caucasians, 7 Hispanics; p = 0.0073), prioritized SPF (95 Caucasians, 10 Hispanics; p = 0.0178), and were more likely to perceive sunscreen as unaffordable (6 Caucasians, 4 Hispanics; p = 0.0269). Analysis by Fitzpatrick Skin Type demonstrated differences in sunscreen utilization, with Types I-III using more compared to Types IV-VI (70 Types I-III, 51 Types IV-VI; p = 0.0173); additionally, Type I-III individuals were significantly more likely to cite cost as barrier to sunscreen purchase (40 Type I-III, 65 Types IV-VI; p < 0.0001). Moreover, lower-income individuals were significantly more likely to perceive sunscreen as unaffordable (12 lower-income, 1 middle & upper income; p = 0.0025) and cited cost as a barrier to purchase (46 lower-income, 59 middle & upper income; p = 0.0146) compared to middle-to-upper income counterparts. Though statistical significance was not established, respondents from middle & upper income groups reported higher sunscreen usage rates compared with their lower-income peers.

CONCLUSIONS AND RELEVANCE

These findings highlight the importance of socioeconomic factors and ethnicity on accessibility to sunscreen and the impact of disparities in utilization among different ethnic and socioeconomic groups.

Reinforcing Photoprotection for Skin of Color: A Narrative Review

Skin of color (SOC) is characterized by increased tendency for tanning and decreased likelihood of sunburns due to the attenuation of sunlight by epidermal melanin. Although this contributes to the decreased incidence of skin cancer among SOC populations, individuals with SOC remain susceptible to various health consequences associated with sun exposure, including non-melanoma skin cancer, photoaging, pigmentary disorders, and photodermatoses - many of which not only present differently, but also disproportionately affect SOC. Prior epidemiological studies have found lower prevalence of sun protection behaviors among individuals with SOC, particularly in sunscreen use, signifying an unmet area for improvement in the prevention of sun-induced dermatologic conditions in these populations. The objective of this narrative review was to summarize the biology and health consequences of sun exposure in SOC, as well as cognitive and behavioral factors that affect the practice of photoprotection behaviors in SOC populations. We also review prior interventions that have been used to enhance photoprotection knowledge and behaviors among individuals with SOC, either in racially and ethnically diverse communities or within specific SOC populations.

Undereducation is afoot: Assessing the lack of acral lentiginous melanoma educational materials for skin of color

Acral lentiginous melanoma (ALM) is a subtype of cutaneous melanoma notorious for poor outcomes that disproportionately affect individuals with skin of color (e.g., African-, Hispanic-, Asian-descent) when compared to mortality rates among non-Hispanic White populations. There are several societal factors that contribute to racial disparities in ALM, including a lack of representative educational material in the context of patient education and medical instruction. This gap in representative information for the US population includes risk of disease, patterns of incidence, and differences in disease presentation in skin of color. The atypical presentation of ALM on acral volar skin sites makes early detection challenging and necessitates an increased index of suspicion on the part of physicians and patients alike. Studies underscoring the importance of early detection in reducing mortality risk make the availability of adequate representative educational materials indispensable.

Melanoma in skin of color: Part II. Racial disparities, role of UV, and interventions for earlier detection

Despite a higher incidence of melanoma among White individuals, melanoma-specific survival is worse among individuals with skin of color. Racial disparities in survival are multifactorial. Decreased skin cancer education focused on people with skin of color, lower rates of screening, increased socioeconomic barriers, higher proportions of more aggressive subtypes, and underrepresentation in research and professional education contribute to delays in diagnosis and treatment. Although high, intermittent UV exposure during childhood has been established as a significant modifiable risk factor for melanoma in individuals with lighter skin phototypes, there are limited data on UV exposure and melanoma risk in people with darker skin phototypes. The second article of this continuing medical education series will examine factors contributing to racial disparities in melanoma-specific survival, discuss the role of UV radiation, and address the need for further research and targeted educational interventions for melanoma in individuals with skin of color.

Risk factors for loss of follow-up after asynchronous dermatology eConsult concerning for skin cancer

Asynchronous electronic consultations (e-consults) can be a useful tool for the screening of cutaneous lesions, but may offer a malpractice risk. We characterized factors affecting initial eConsult office follow-up in a cohort of patients with documented neoplasm of uncertain behavior. Patients with an ICD 10 code of neoplasm with uncertain behavior (D48.5) at The Ohio State University that received an E-consult order from May 2017 to May 2021 were queried. Information collected included patient demographics, status of follow-up in-office appointment, referral status, and health care utilization. In-office follow-up appointments were defined as completed, cancelled/no-show or no-contact. 667 patients with a diagnosis of D48.5 were identified as having completed an eConsult. 427 (64%) patients had a documented phone/electronic message notifying the patient of the results of the eConsult. Year of encounter (0.88 [0.79-0.97]) and number of previously completed ambulatory visits (0.86 [0.77-0.96]) were significantly associated with documentation of phone/electronic message in the univariate and multivariate model. 429 (84%) patients had a dermatology office follow-up encounter while 82 (16%) had no appointment scheduled. Language spoken, referral status and race were significant in the univariate model, though race was the only significant variable in the multivariate model (P < 0.003). Asynchronous electronic consults to assess possible cutaneous neoplasms is an important tool for population screening of skin cancer. Dermatologists and health systems implementing an eConsult model for screening purposes should be aware of risk factors for loss of follow-up. Additional systems need to be implemented to ensure minorities and non-native English speakers are obtaining adequate dermatologic care.

Delay in Seeking Medical Attention and Diagnosis in Chinese Melanoma Patients: A Cross-Sectional Study

Melanoma is a highly malignant skin tumor, and prolonged delay in seeking medical attention (DSMA) and delay in diagnosis (DD) may result in poor prognoses. Through a web-based questionnaire, we explored the related factors affecting the DSMA and DD of melanoma in a Chinese population. A total of 112 valid answer sheets were received. After obtaining the relevant information, we analyzed the factors associated with DSMA and DD. The median time of DSMA was 8.0 (quartiles: 1.0, 29.3) months, and the median of patients' DD was 1.0 (quartiles: 1.0, 8.3) month. The subsequent analysis showed that DSMA and DD were positively correlated to age and negatively correlated to education background and annual household income. Patients with a history of tumors or previous health-seeking behavior because of other skin lesions had significantly longer DSMA than those without. Patients who sought medical help at general tertiary hospitals for the first time had a significantly shorter DD than those who chose other hospitals. Our study found that DSMA and DD are associated with factors such as age, education, income, and patients' histories. Secondary prevention of Chinese melanoma should be strengthened to reduce DSMA and DD to improve patients' prognoses.

The Bias of Physicians and Lack of Education in Patients of Color With Melanoma as Causes of Increased Mortality: A Scoping Review

Minorities, particularly non-White minorities, often encounter implicit biases from healthcare professionals that may impact their standard of care and quality of life. The study of dermatology has long been based on Whites, unintentionally affecting the treatment of non-White patients. Melanoma, although mostly curable, can become fatal in those presenting with advanced stages at diagnosis. Despite being rare in racial minorities, melanoma is associated with a worse prognosis among them compared to White populations. In light of this, the objective of this study was to determine the role of education in preventing biases and improving the diagnosis and treatment of melanoma in minority groups to improve patient outcomes. This study was designed as a scoping review to gather evidence on the impact of implicit bias and lack of education on the treatment of melanoma in people of color. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched for peer-reviewed studies involving melanoma, education, and treatment bias in people of color on the databases PubMed, Medline EBSCO, CINAHL, and Cochrane. The data were extracted pertaining to the following main aspects: (1) risk factors, (2) surveys of current knowledge, and 3) educational interventions. This scoping review identified socioeconomic factors, bias, and lack of education in minority populations as causes of increased mortality rates in melanoma. Moreover, because preventative dermatology is largely based on White skin types, incorporating darker skin tones into education will help dispel implicit bias. Additionally, there is evidence to indicate that current patient knowledge and understanding of skin cancer is inaccurate among many and can be significantly improved through educational interventions, such as brochures and videos. Further educational interventions may be beneficial to increase understanding of melanoma in populations of color to address health disparities in dermatological care.

Racial/ethnic health disparities in dermatology in the United States, part 1: Overview of contributing factors and management strategies

Racial or ethnic disparities are prevalent in the field of dermatology. Part 1 of this continuing medical education series aims to elucidate contributors to racial and ethnic disparities within dermatology and highlight potential actionable steps to combat these disparities. We review access to care, workforce diversity, cultural competency, implicit bias, dermatologic education material, patient education, and clinical research. Part 2 of the continuing medical education series will address disease-specific inequities that influence the clinical practice of dermatology.

Advanced basal cell carcinoma: What dermatologists need to know about diagnosis

Basal cell carcinoma (BCC) is the most common human cancer, with approximately 3.6 million cases diagnosed each year. About 2000 deaths annually in the United States are attributed to basal and squamous cell skin cancers. There is a direct link between ultraviolet exposure and the development of BCC, as UV exposure damages DNA and induces mutations in tumor suppressor genes. Aberrations in the hedgehog pathway can also result in BCC, highlighted by the fact that most cases of sporadic BCCs have been found to have mutations in different genes involved in the hedgehog pathway. There are several genetic syndromes that are associated with BCCs, including basal cell nevus syndrome, xeroderma pigmentosum, Bazex-Dupré-Christol syndrome, Rombo syndrome, and Oley syndrome. Other risk factors include age, male gender, occupational hazards, radiation, and immunosuppression. BCCs are not typically staged but are instead stratified by their risk of recurring or metastasizing. Locally advanced BCCs are those tumors that are not amenable to surgery or radiation therapy.

Cross-sectional study of acral melanoma awareness in a group of South African final phase medical students

BACKGROUND

Acral melanoma refers to melanoma arising on the palms, soles and nail unit, which are sun-protected areas and ultraviolet exposure is not a risk factor. Acral melanoma is associated with a poorer prognosis than other melanoma subtypes most likely due to the high rates of delayed diagnosis. Acral melanoma affects all skin types equally. There is a misconception that people with more pigmented skin types (Fitzpatrick 4-6) do not develop melanoma, due to the protective effect of melanin.

OBJECTIVES

The aim of the study was to determine acral melanoma knowledge and awareness of a group of South African, final phase medical students.

METHODS

This was a quantitative and cross-sectional study. A questionnaire consisting of 20 clinical images of skin lesions requiring a diagnosis and management plan was distributed. Responses to six images of melanomas were analysed. Further questions to measure acral melanoma knowledge and related issues were included in the study. A biostatistician appropriately managed statistical analysis.

RESULTS

Hundred and one final phase medical students' answers were gathered and analysed. Only 7.9% of the participants diagnosed all six melanomas correctly; 61.4% correctly diagnosed ≥50% of the melanomas. While 77.2% of the participants identified all non-acral cutaneous melanoma correctly, only 8.9% identified all acral melanomas. However, of all participants making the correct diagnosis, >90% selected the appropriate management plan (urgent referral).

LIMITATIONS

This study examined a small sample of trainee healthcare workers. The results cannot be assumed to apply to all South African healthcare workers. Responses given in a questionnaire may not reflect actual behaviour. The dermatology division in question has made acral melanoma a research priority, thus acral melanoma knowledge in this group may in fact be better than in other institutions.

CONCLUSION

The present study demonstrates that groups of imminent doctors have low rates of recognition of melanoma, particularly acral melanoma. This is consistent with high levels of primary misdiagnosis of acral melanoma reported in the literature. Fortunately, these participants managed the melanomas they diagnosed appropriately in >90% of cases. This confirms that the deficit in the participant group is awareness and knowledge. Those aware of the disease immediately acknowledged the need for urgent referral.

Photoprotection for Skin of Color

Photoprotection behaviors can mitigate skin damage caused by ultraviolet radiation, and common methods include seeking shade, avoiding sun exposure during peak daylight hours, wearing sun-protective clothing, applying sunscreen, and using sunglasses. While the role of sun protection in preventing sunburns, photoaging, and skin cancer is well established in fair-skinned populations, individuals with skin of color (SOC) are presumed to suffer fewer negative effects from solar radiation. Thus, the importance of photoprotection in this population is understudied and may be underestimated. In SOC populations, sun exposure is known to cause pigmentary disorders, photoaging, and basal cell carcinoma (BCC), highlighting the potential benefits of photoprotection. Although SOC populations tend to practice photoprotection by seeking shade and wearing sun-protective clothing, survey and interview-based studies have consistently found relatively low use of sunscreen among these populations. Common motivators for photoprotection in individuals with SOC include preventing sunburn and pigmentation, with the prevention of skin cancer being a less important reason. As a skin cancer risk behavior, indoor tanning is relatively rare in SOC populations, but its use may increase with acculturation to US norms. While more studies are necessary to clarify whether photoprotection behaviors may decrease skin cancer-related mortality in SOC populations, regular dermatologic care and counseling on photoprotection remain essential in patients with SOC for overall skin health.

Etiologies of Melanoma Development and Prevention Measures: A Review of the Current Evidence

Simple Summary

Melanoma constitutes a major public health risk, with the rates of diagnosis increasing on a yearly basis. Monitoring for risk factors and preventing dangerous behaviors that increase melanoma risk, such as tanning, are important measures for melanoma prevention. Additionally, assessing the effectiveness of various methods to prevent sun exposure and sunburns—which can lead to melanoma—is important to help identify ways to reduce the development of melanoma. We summarize the recent evidence regarding the heritable and behavioral risks underlying melanoma, as well as the current methods used to reduce the risk of developing melanoma and to improve the diagnosis of this disease.

Abstract

(1) Melanoma is the most aggressive dermatologic malignancy, with an estimated 106,110 new cases to be diagnosed in 2021. The annual incidence rates continue to climb, which underscores the critical importance of improving the methods to prevent this disease. The interventions to assist with melanoma prevention vary and typically include measures such as UV avoidance and the use of protective clothing, sunscreen, and other chemopreventive agents. However, the evidence is mixed surrounding the use of these and other interventions. This review discusses the heritable etiologies underlying melanoma development before delving into the data surrounding the preventive methods highlighted above. (2) A comprehensive literature review was performed to identify the clinical trials, observational studies, and meta-analyses pertinent to melanoma prevention and incidence. Online resources were queried to identify epidemiologic and clinical trial information. (3) Evidence exists to support population-wide screening programs, the proper use of sunscreen, and community-targeted measures in the prevention of melanoma. Clinical evidence for the majority of the proposed preventive chemotherapeutics is presently minimal but continues to evolve. (4) Further study of these chemotherapeutics, as well as improvement of techniques in artificial intelligence and imaging techniques for melanoma screening, is warranted for continued improvement of melanoma prevention.

Cost-Effectiveness Analysis of Dabrafenib Plus Trametinib and Vemurafenib as First-Line Treatment in Patients with BRAF V600 Mutation-Positive Unresectable or Metastatic Melanoma in China

Objective: To evaluate the cost-effectiveness of dabrafenib plus trametinib combination therapy versus vemurafenib as first-line treatment in patients with BRAF V600 mutation-positive unresectable or metastatic melanoma from a healthcare system perspective in China. Methods: This study employed a partitioned survival model with three health states (progression-free survival, post-progression survival and dead) to parameterize the data derived from Combi-v trial and extrapolated to 30 years. Health states’ utilities were measured by EQ-5D-3L, also sourced from the Combi-v trial. Costs including drug acquisition costs, disease management costs and adverse event costs were based on the Chinese Drug Bidding Database and physician survey in China. The primary outcomes of the model were lifetime costs, life-years (LYs), quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratio (ICER). Deterministic and probabilistic sensitivity analyses were conducted, respectively. Result: Dabrafenib plus trametinib is projected to increase a patient’s life expectancy by 0.95 life-years over vemurafenib (3.03 vs. 2.08) and 1.09 QALY gains (2.48 vs. 1.39) with an incremental cost of $3833. The incremental cost-effectiveness ratio (ICER) was $3511 per QALY. In the probabilistic sensitivity analyses, at a threshold of $33,357 per QALY (three times the gross domestic product (GDP) per capita in China in 2020), the probability of dabrafenib plus trametinib being cost-effective was 90%. In the deterministic sensitivity analyses, the results were most sensitive to the dabrafenib plus trametinib drug costs, vemurafenib drug costs and discount rate of cost. Conclusion: Dabrafenib plus trametinib therapy yields more clinical benefits than vemurafenib. Using a threshold of $33,357 per QALY, dabrafenib plus trametinib is very cost-effective as compared with vemurafenib in China.

Comparative study of cutaneous melanoma and its associated issues between people of African decent and Caucasians

Cutaneous melanoma is uncommon in people of African descent unlike their Caucasian counterparts. This rarity of cutaneous melanoma in people of African descent makes studies in this group difficult. In the few studies that are available, several differences exist in the incidence, disease severity, course of the disease, treatment modalities and survival rates between these two groups. Observed difference in cutaneous melanoma between people of African descent and Caucasians include; a higher incidence and better prognosis in Caucasians, a low awareness of melanoma, no definite risk factors, presentation with advanced disease, poor melanoma specific survival in people of African descent. Other differences are a better UV-induced DNA damage recovery, acral as opposed to truncal melanoma, female preponderance and lack of preventive measures in people of African descent.

Assessment of Skin Phenotype Representation in a Popular Medical Licensing Educational Resource

This cross-sectional study examines the representation of darker skin phenotypes in tools used by students in preparation for medical licensure testing.

Racial and ethnic disparities in melanoma awareness: A cross-sectional survey

BACKGROUND

Hispanics are among the fastest growing population in the United States and are predicted to account for one third of the nation by 2060. Although melanoma is more common among white patients, Hispanic individuals are at greater risk of late-stage diagnosis, increased tumor thickness, and poorer survival.

OBJECTIVE

To better understand public awareness of melanoma and evaluate change over the last 21 years, particularly among high-risk minority populations.

METHODS

A cross-sectional survey collecting information on knowledge and awareness of melanoma was conducted on 285 participants from May through November 2017.

RESULTS

Approximately 39% of participants were unaware of melanoma. Sixty-five percent successfully identified early signs of disease. Approximately 86% of Fitzpatrick skin types (FST) I and II identified melanoma as a cancer, compared to 46.3% of FST III and IV and 57.6% of FST V and VI. Hispanic particiapnts were less likely to know what melanoma was compared to white participants (odds ratio [OR], 0.27; 95% confidence interval [CI], 0.65-0.11; P = .0037). US natives (OR, 2.38; 95% CI, 5.56-1.04; P = .0403) and patients with any college education (OR, 2.86; 95% CI, 5.26-1.54; P = .0007) were more likely to know the meaning of melanoma.

CONCLUSION

White participants and those with any college education were more likely to know the meaning of melanoma. Individuals of racial and ethnic minorities would benefit from educational programs geared toward early detection.

The ongoing racial disparities in melanoma: An analysis of the Surveillance, Epidemiology, and End Results database (1975-2016)

BACKGROUND

Although most patients with cutaneous melanoma are non-Hispanic whites (NHWs), minorities consistently suffer worse melanoma-specific survival (MSS). Much of the literature comes from analyses of registries from the 1990s and 2000s.

OBJECTIVE

We sought to evaluate whether and to what degree racial disparity in MSS persists since 2010.

METHODS

We analyzed 381,035 patients from the Surveillance, Epidemiology, and End Results registry. Race categories included Hispanic, NHW, non-Hispanic black (NHB), non-Hispanic Asian or Pacific Islander (NHAPI), and non-Hispanic American Indian/Alaska Native (NHAIAN). We evaluated the association between MSS and race in 3 time periods: before the year 2000, 2000 to 2009, and 2010 or later. NHW was the reference group for all analyses.

RESULTS

Racial disparity worsened from before the year 2000 to 2010 or later for Hispanic (P < .001), NHB (P = .024), and NHAPI (P < .001) patients. Across all minority groups, patients with localized disease suffered increasing disparity (P = .010 for Hispanic, P < .001 for NHB, P = .023 for NHAPI, and P = .042 for NHAIAN patients). Among those with regional and distant disease, Hispanic patients were the only minority to experience worsening disparity (P = .001 and P = .019, respectively).

LIMITATIONS

Lack of immunotherapy and targeted treatment information.

CONCLUSIONS

Racial disparity in MSS is worsening. Improving postdiagnosis management for minorities with localized disease is imperative to mitigate disparity and improve survival.

The impact of demographics, socioeconomics, and health care access on melanoma outcomes

Disparities in melanoma care exist in the United States. Disparities in provider type, patient demographics, place of residence, insurance status, socioeconomic status, race/ethnicity, and age impact melanoma outcomes. Melanomas detected by dermatologists are thinner, at an earlier stage, and have better survival outcomes compared with detection by primary care providers or patients. Lower socioeconomic status, race/ethnicity, and place of residence are associated with decreased access to or use of dermatologists, or both, and more advanced melanomas at diagnosis. Additionally, uninsured and publicly insured individuals are more likely to present with late-stage melanomas, resulting in worse outcomes. This review provides a comprehensive overview of how structural and patient-level characteristics influence melanoma outcomes in order to inform clinical care and health care policy as it relates to addressing gaps in melanoma care.

Basal Cell Carcinoma, Squamous Cell Carcinoma, and Cutaneous Melanoma in Skin of Color Patients

Skin cancers are relatively rare in patients with skin of color; however, they are an important public health concern because of disparities in patient outcomes. Gaps in skin cancer knowledge exist because of lack of large-scale studies involving people of color, and limitations in data collection methods and skin classification paradigms. Additional research is needed to address questions regarding risk and reasons for disparate skin cancer outcomes in these patients. We summarize the clinical and epidemiologic features for basal cell carcinoma, squamous cell carcinoma, and melanoma and touch on some of their unique features in patients with skin of color.

The Odds of Stage IV Melanoma Diagnoses Based on Socioeconomic Factors

BACKGROUND

When diagnosed at stage 0-I, melanoma has a 5-year survival rate of 92% to 100% in comparison with stage IV, which has a 5-year survival rate of 15% to 20%.

OBJECTIVE

The objective of this article is to identify what socioeconomic and demographic factors were associated with increased odds in receiving a delayed melanoma diagnosis.

METHODS

This study analyzed the odds of 108,628 patients from the National Cancer Database who were diagnosed between 2004 and 2012 with American Joint Committee on Cancer stage 0-I and stage IV based on race, sex, insurance type, income, facility type, and education.

RESULTS

We identified significantly (P < .05) increased odds of stage IV primary melanoma diagnosis in those who had nonprivate insurance, including Medicare (odds ratio [OR] = 1.31, 95% confidence interval [CI]: 1.19-1.45), other government insurance (OR = 2.19, 95% CI: 1.61-2.98), Medicaid (OR = 6.97, 95% CI: 5.98-8.13), or no insurance (OR = 5.10, 95% CI: 4.41-5.91). Increased odds of late-stage melanoma were also associated with male sex (OR = 1.46, 95% CI: 1.36-1.57), race and ethnicity other than non-Hispanic white such as Hispanic whites (OR = 1.49, 95% CI: 1.15-1.92) or African Americans (OR=4.81, 95% CI: 3.75-6.18), and who had decreased education (OR = 1.19, 95% CI: 1.09-1.30). There was not a significant increase in odds of late-stage melanoma in patients from areas with the lowest levels of income compared with areas of highest income.

CONCLUSIONS

Certain socioeconomic and demographic factors are associated with odds of a later-stage melanoma diagnosis.

Racial disparities, cancer and response to oxidative stress

At the intersection of genetics, biochemistry and behavioral sciences, there is a largely untapped opportunity to consider how ethnic and racial disparities contribute to individual sensitivity to reactive oxygen species and how these might influence susceptibility to various cancers and/or response to classical cancer treatment regimens that pervasively result in the formation of such chemical species. This chapter begins to explore these connections and builds a platform from which to consider how the disciplines can be strengthened further.

Knowledge and practices of primary care providers on skin cancer and skin self-examination

OBJECTIVE

To determine the knowledge and practices related to skin cancer and skin self-examination of primary care providers.

METHOD

This cross-sectional descriptive study was conducted in Turkey. The study was carried out in primary health centers such as family health centers, community health centers, early cancer detection centers and family planning centers in 2016-2017. Participants' socio-demographic characteristics, their knowledge and practices related to skin cancer, skin cancer risk factors and skin self-examination were determined.

RESULTS

The study population included 94 primary care providers. The symptoms of which the participants were most aware were changes in the color of moles or skin spots (95.71%), and of which participants were the least aware was the itching of a mole (71.43%). Among participants, the most recognized risk factor was having fair skin (97.14%), whereas the least known was the presence of birthmarks (24.29%). The mean scores the participants obtained from the questionnaire were as follows: 5.39±1.61 for skin cancer risk factors and 10.47±2.73 for skin cancer symptoms. Of the participants, 14.29% received training on skin self-examination, 38.57% knew how to perform skin self-examination, and 67.14% did not perform skin self-examination. Of the participants, 61.7% did not perform skin self-examination because they did not know what to look for. Of the participants, 85.71% did not have continuing education/workshop about skin self-examination after graduation.

CONCLUSION

Although the primary care providers' knowledge of skin cancer symptoms was adequate, their knowledge of skin cancer risk factors was not sufficient. Primary care providers' knowledge of skin self-examination was good, but they did not perform skin self-examination adequately.

Inpatient burden of pediatric dermatology in the United States

BACKGROUND/OBJECTIVES

It is known that inpatient care accounts for a significant portion of health care expenditures, but the national burden of inpatient pediatric dermatology is poorly characterized. We sought to assess risk factors, conditions, and financial costs associated with pediatric hospitalizations for skin disease.

METHODS

We performed a cross-sectional study of pediatric dermatology hospitalizations using the 2012 Kids' Inpatient Database, which samples 80% of non-birth-related pediatric admissions from 44 states to generate national estimates. The demographic characteristics of children admitted for dermatologic and nondermatologic conditions were compared, and the financial costs of these admissions were analyzed.

RESULTS

In 2012, there were 74 229 (95% confidence interval (CI) = 68 620-79 978) pediatric dermatology hospitalizations, accounting for 4.2% of all pediatric admissions and $379.8 million (95% CI = $341.3-418.4 million) in health care costs. Bacterial infections (n = 59 115, 95% CI = 54 669-63 561), viral diseases (n = 3812, 95% CI = 3457-4167), and noncancerous skin growths (n = 2931, 95% CI = 2318-3545) were the most common conditions requiring hospitalization. The highest mean cost per hospitalization was for admissions for cutaneous lymphomas ($58 294, 95% CI = $31 694-84 893), congenital skin abnormalities ($24 186, 95% CI = $16 645-31 728), and ulcers ($17 064, 95% CI = $14 683-19 446). Pediatric dermatology hospitalizations were most strongly associated with living in a low-income community (odds ratio (OR) = 1.22, 95% CI = 1.16-1.29) and the South (OR = 1.32, 95% CI = 1.19-1.46) and being uninsured (OR = 1.35, 95% CI = 1.26-1.45) or having Medicaid insurance (OR = 1.17, 95% CI = 1.13-1.22).

CONCLUSION

Skin disease is a common cause of hospitalizations in children, and there are disparities in these admissions that could reflect inadequate access to outpatient pediatric dermatologists.

Various Dermatoses What the Patients with Cutaneous Melanoma Had Anxiety for the Recurrence during Postoperative Surveillance

BACKGROUND

The incidence and mortality rates associated with cutaneous melanoma (CM) have steadily increased over the last 20 years. Even with successful treatment, melanoma patients usually experience substantial anxiety regarding the development of terrible recurrence. To date, few studies have investigated various dermatoses what the patients with CM had anxiety for the recurrence during postoperative surveillance (Dw).

OBJECTIVE

To describe various Dw and to evaluate the risk of subsequent malignant skin disease in patients with CM.

METHODS

We performed a prospective study between August 2002 and August 2015.

RESULTS

Fifty-six patients presented with a total of 68 Dw. Among them, melanocytic nevus was the most common (n=27), followed by seborrheic keratosis (n=9) and CM recurrence (n=7). Approximately 5.6% of the lesions were diagnosed as malignant skin diseases. This was a single-center study, so the prevalence of malignant skin diseases following primary melanoma may not represent that of all patients with CM.

CONCLUSION

The results of this study can be referred by dermatologists dealing with melanoma especially when CM patients have too excessive or unrealistic anxiety for melanoma recurrence during postoperative surveillance of CM. However, the importance of postoperative surveillance must still be emphasized because of real risk of melanoma recurrence and other malignant skin.

Melanoma Perception in People of Color: A Targeted Educational Intervention

BACKGROUND

Although melanoma is more common in non-Hispanic Whites, ethnic minorities face a greater risk of melanoma-related mortality, which may be partially attributed to presentation at atypical sites and a lack of awareness.

OBJECTIVE

Our objective was to assess the effectiveness of a melanoma educational intervention targeted towards people of color.

DESIGN

Participants received one of two scripted melanoma educational interventions in the summer of 2015. They completed surveys before the intervention, immediately post-intervention, and 2 months post-intervention.

SETTING

Dermatology clinic at an academic hospital.

PARTICIPANTS

A consecutive sample of 100 participants who self-identified as African American, Asian, or Hispanic were recruited following their dermatology visit. In total, 70 participants completed the 2-month follow-up questionnaire.

INTERVENTION

The comparison intervention group received an educational intervention using a conventional pamphlet on the 'ABCDEs' (Asymmetry, Borders, Color, Diameter, Evolution) of melanoma. The targeted intervention group received a modified pamphlet that included a skin of color section, the nomenclature "melanoma skin cancer", and an image of an individual performing a skin self-examination with the help of a friend.

MAIN OUTCOMES AND MEASURES

Melanoma knowledge, perceived risk for developing melanoma, and skin self-examination practices were assessed through self-reported questionnaires.

RESULTS

Among the 100 participants, 78% self-identified as African American, 11% as Asian, and 11% as Hispanic. Both groups experienced a similar increase in melanoma knowledge that was retained at 2 months. Perceived personal risk for developing melanoma increased more in the targeted intervention group immediately post-intervention (p = 0.015), but this difference no longer existed between the groups at the 2-month follow-up. The targeted intervention group also demonstrated a greater increase in skin self-examinations (p = 0.048) and knowledge of warning signs to look for when examining the skin (p = 0.002) at the 2-month follow-up.

CONCLUSIONS AND RELEVANCE

The educational intervention targeted towards people of color resulted in increased skin self-examinations. Educational material that is relevant to ethnic minorities may better promote early detection and help to decrease the disparity in melanoma-related morality rates.

TRIAL REGISTRATION

Clinicaltrials.gov registration number NCT02437305.

A Trial Online Educational Melanoma Program Aimed at the Hispanic Population Improves Knowledge and Behaviors

BACKGROUND

Hispanic individuals who suffer from melanoma are diagnosed later and have a worse prognosis. Because the Hispanic population is one of the fastest growing in the United States, it is important to spread awareness of melanoma.

OBJECTIVE

The study aimed to evaluate whether an online educational video about skin cancer could improve knowledge about melanoma and encourage self-skin examinations (SSE).

METHODS

The authors directed Hispanic patients to an online survey, which assessed for knowledge about melanoma risk factors and prevention. This was followed by a 5-minute online video about melanoma. A second survey was sent immediately after the video, and a third survey was sent 1 month later. All project materials were in Spanish and available online.

RESULTS

Eighty-six participants completed the full experiment. After watching the online video, a significantly higher proportion of participants provided correct answers for melanoma risk factors and prevention techniques. A similar increase was seen in the number of individuals who reported performing SSEs.

CONCLUSION

This study provides evidence that an online educational video targeted at the Hispanic population has potential to improve melanoma awareness. This type of intervention may lead to earlier diagnosis and better prognosis for Hispanic individuals.

Skin cancer knowledge and attitudes in the region of Fez, Morocco: a cross-sectional study

BACKGROUND

The prevalence of skin cancers is constantly increasing in Morocco, and they have gradually become more aggressive due to a significant delay in the diagnosis. Our aim was to assess the levels of awareness and the influencing factors related to skin cancer knowledge in Morocco.

METHODS

This cross-sectional study was carried out in Morocco through the medium of a validated questionnaire, which contained several items - demographics, skin cancer knowledge and attitudes towards skin cancer patients- during a period of 1 year (2014).

RESULTS

Out of the 700 participants enrolled in the study, 17.9% had never heard of skin cancer, 32.5% had a low score of skin cancer knowledge, 66.7% had a moderate score, and only 0.85% had a high score of skin cancer knowledge. Further, 15.1% of the participants were under the assumption that this cancer is contagious. The sun was the most incriminated risk factor in skin cancer occurrence by 74.3% of the participants, and 57.9% of them believed that prevention is important through using various means of photoprotection. After univariate and multivariate analysis, the influencing factors related to the skin cancer knowledge in Morocco were: the socioeconomic status (P = 0.003, OR = 7. 3) and the educational level (p < 0.001, OR = 20. 9).

CONCLUSIONS

Due to the lack of knowledge or the underestimation of skin cancer in our study population, efforts are needed to promote skin cancer surveillance behaviors in Morocco.

Prognostic factors and disease-specific survival among immigrants diagnosed with cutaneous malignant melanoma in Sweden

Little is known about cutaneous malignant melanoma (CMM) among immigrants in Europe. We aimed to investigate clinical characteristics and disease-specific survival among first- and second-generation immigrants in Sweden. This nationwide population-based study included 27,235 patients from the Swedish Melanoma Register diagnosed with primary invasive CMM, 1990-2007. Data were linked to nationwide, population-based registers followed up through 2013. Logistic regression and Cox regression models were used to determine the association between immigrant status, stage and CMM prognosis, respectively. After adjustments for confounders, first generation immigrants from Southern Europe were associated with significantly more advanced stages of disease compared to Swedish-born patients [Stage II vs. I: Odds ratio (OR) = 2.37, 95% CI = 1.61-3.50. Stage III-IV vs I: OR = 2.40, 95% CI = 1.08-5.37]. The ORs of stage II-IV versus stage I disease were increased among men (OR = 1.9; 95% CI = 1.1-3.3; p = 0.020), and women (OR = 4.8; 95% CI = 2.6-9.1; p < 0.001) in a subgroup of immigrants from former Yugoslavia compared to Swedish-born patients. The CMM-specific survival was significantly decreased among women from former Yugoslavia versus Swedish-born women [hazard ratio (HR)=2.2; 95% CI = 1.1-4.2; p = 0.043]. After additional adjustments including stage, the survival difference was no longer significant. No survival difference between the second generation immigrant group and Swedish-born patients were observed. In conclusion, a worse CMM-specific survival in women from former Yugoslavia was associated with more advanced stages of CMM at diagnosis. Secondary prevention efforts focusing on specific groups may be needed to further improve the CMM prognosis.

Acral melanocytic lesions in the United States: Prevalence, awareness, and dermoscopic patterns in skin-of-color and non-Hispanic white patients

BACKGROUND

Acral lentiginous melanoma has increased mortality compared with other melanoma subtypes and disproportionately affects ethnic minorities. Acral melanocytic lesions have not been well studied in diverse populations of the United States.

OBJECTIVE

We sought to assess the prevalence, awareness, and dermoscopic patterns of acral melanocytic lesions in skin-of-color and non-Hispanic white patients.

METHODS

We prospectively examined the palms and soles of 1052 patients presenting to dermatology clinics in New York, NY, and Miami, FL, from October 2013 to April 2015.

RESULTS

Acral melanocytic lesions were observed in 36% of our cohort. Skin-of-color patients were more likely to have acral melanocytic lesions than non-Hispanic white patients (P < .01). Acral melanocytic lesions correlated with increased mole counts, particularly on non-Hispanic white patients. The majority of lesions demonstrated benign dermoscopic patterns. We observed 2 lesions with the parallel ridge pattern in our cohort, both found to be atypical nevi on biopsy specimen. Patients often lacked awareness of the presence of their lesions.

LIMITATIONS

Interobserver variability in assessing dermoscopic patterns is a limitation.

CONCLUSIONS

Melanocytic lesions of the palms and soles are common, particularly in a cohort of multiple ethnicities from the United States. Dermoscopy of acral lesions is an important clinical tool for diagnosis and management of these lesions.

Clinical characteristics and prognostic indicators for metastatic melanoma: data from 446 patients in north China

Melanoma is an extremely rare tumor in Asia. This retrospective study aimed to identify the clinical characteristics and prognostic factors of metastatic melanoma patients at Tianjin Medical University Cancer Hospital over the last 30 years. Survival analysis was performed with Kaplan-Meier, log-rank test, and multivariate Cox regression method using SPSS 19.0 software. The 1-, 2-, and 5-year survival rates of metastatic melanoma patients were 52, 32, and 16 %, respectively. Median overall survival (OS) was 13.5 months, median progression-free survival (PFS) 9.0 months, and median disease-free survival 20.3 months. Furthermore, patients with a single metastatic site achieved better OS and PFS than those with two or more metastatic lesions (OS 21.6 vs. 8.9 months, P < 0.001; PFS 11.3 vs. 7.1 months, P < 0.001). Survival times of patients with visceral metastases were the shortest (OS 8.5 months; PFS 7.5 months). Specifically, patients with primary mucosal lesions had a worse OS (9.7 months) and PFS (6.8 months) than those with acral (19.2 and 15.6 months, respectively) or non-acral primary lesions (11.8 and 11.1 months, respectively). The treatment of advanced melanoma was unitary, and prognoses of patients with metastatic melanoma in China were poor. Visceral metastasis, multiple metastatic sites, and primary mucosal lesions were significant predictors of survival of patients with metastatic melanoma. Those with primary mucosal lesions had significantly worse survivals than those with primary cutaneous lesions. More active involvement in clinical studies and more feedback on various treatment options are required.

Prevalent Health Concerns Among African American Women Belonging to a National Volunteer Service Organization (The Links, Incorporated)

OBJECTIVE

African American women bear a disproportionate burden of cardiovascular disease (CVD) and cancer. The purpose of this study was to identify prevalent health concerns among African American women who are members of The Links, Incorporated (Links), a large national service organization with health programming for communities of color.

METHODS

Survey data (n = 391) were collected during the 2012 Links National Assembly. Twenty-six health issues were presented within five groups: cancer, CVD, pulmonary disease, chronic conditions, and behavioral health. For each issue, women indicated if it was a concern for "you/your family" or "the African American community" via check-boxes. Differences in the proportions for "you/your family" and "the African American community" were evaluated using the McNemar test.

RESULTS

Hypertension was the most frequently endorsed concern for you/your family (79 %); 73 % indicated this was a concern for the African American community. Sickle cell anemia was the most frequently endorsed concern for the African American community (77 %). Melanoma was the least endorsed health issue overall (15 % you/your family, 55 % community). Breast was the most frequently endorsed cancer concern, while lung was among the least. For 23 out of 26 health issues, the proportion concerned was greater for the "African American community" than for "you/your family" (all p < 0.05).

CONCLUSION

CVD and breast cancer were salient concerns; both are topics for which national awareness campaigns and Links health programming exist. Comparatively lower concern was observed for melanoma, a cancer with known survival disparities, and for lung cancer, a leading cause of death in women.

Sun Protection Behaviors Associated with Self-Efficacy, Susceptibility, and Awareness among Uninsured Primary Care Patients Utilizing a Free Clinic

Background. Skin cancer is the most commonly diagnosed form of cancer in the United States (US). However, knowledge, behaviors, and attitudes regarding sun protection vary among the general population. The purpose of this study is to examine sun protection behaviors of low-income primary care patients and assess the association between these health behaviors and the self-efficacy, susceptibility, and skin cancer awareness. Methods. Uninsured primary care patients utilizing a free clinic (N = 551) completed a self-administered survey in May and June 2015. Results. Using sunscreen was the least common tactic among the participants of this study. Skin cancer awareness and self-efficacy are important to improve sun protection behaviors. Spanish speakers may have lower levels of skin care awareness compared to US born and non-US born English speakers. Male and female participants use different sun protection methods. Conclusion. It is important to increase skin cancer awareness with self-efficacy interventions as well as education on low-cost sun protection methods. Spanish speaking patients would be a target population for promoting awareness. Male and female patients would need separate gender-specific sun protection education. Future studies should implement educational programs and assess the effectiveness of the programs to further promote skin cancer prevention among underserved populations.

Melanoma risk perception and prevention behavior among African-Americans: the minority melanoma paradox

Introduction

Melanoma is the most deadly type of skin cancer with 75% of all skin cancer deaths within the US attributed to it. Risk factors for melanoma include ultraviolet exposure, genetic predisposition, and phenotypic characteristics (eg, fair skin and blond hair). Whites have a 27-fold higher incidence of melanoma than African-Americans (AA), but the 5-year survival is 17.8% lower for AA than Whites. It is reported continuously that AA have more advanced melanomas at diagnosis, and overall lower survival rates. This minority melanoma paradox is not well understood or studied.

Objective

To explore further, the possible explanations for the difference in melanoma severity and survival in AA within the US.

Methods

Qualitative review of the literature.

Results

Lack of minority-targeted public education campaigns, low self-risk perception, low self-skin examinations, intrinsic virulence, vitamin D differences, and physician mistrust may play a role in the melanoma survival disparity among AA.

Conclusion

Increases in public awareness of melanoma risk among AA through physician and media-guided education, higher index of suspicion among individuals and physicians, and policy changes can help to improve early detection and close the melanoma disparity gap in the future.
