Abstract
Rickettsia africae is a tick-borne bacteria known to cause African tick bite fever (ATBF). While the disease was first described more than 100 years ago, knowledge of transmission risk factors and disease burden remain poorly described. To better understand the burden of R. africae, this article reviewed and summarized the published literature related to ATBF epidemiology and clinical management. Using a systematic approach, consistent with the PRISMA guidelines, we identified more than 100 eligible articles, including 65 epidemiological studies and 41 case reports. Most reports described R. africae in ticks and livestock, while human studies were less common. Human disease case reports were exclusively among returning travellers from non-endemic areas, which limits our disease knowledge among at-risk populations: people living in endemic regions. Substantial efforts to elucidate the ATBF risk factors and clinical manifestations among local populations are needed to develop effective preventative strategies and facilitate appropriate and timely diagnosis.

Abstract
INTRODUCTION The worldwide incidence of melanoma has increased in the last 40 years. Our aim was to describe the clinic-pathological characteristics and outcomes of three cohorts of patients diagnosed with melanoma in a Latin-American cancer institute during the last 20 years. METHODS We evaluated three retrospective patient cohorts diagnosed with melanoma at Instituto Nacional de Enfermedades Neoplasicas (INEN), a public hospital in Lima, Peru, for the years 2005-2006, 2010-2011, and 2017-2018. Survival rate differences were assessed using the Log-rank test. RESULTS Overall, 584 patients were included (only trunk and extremities); 51% were male, the mean age was 61 (3-97) years, and 48% of patients resided in rural areas. The mean time to diagnosis was 22.6 months, and the mean Breslow thickness was 7.4 mm (T4). Lower extremity was the most common location (72%). A majority of the patients (55%) had metastases at the time of presentation, with 36% in stage III and 19% in stage IV. Cohorts were distributed as 2005-2006 (n = 171), 2010-2011 (n = 223), and 2017-2018 (n = 190). No immunotherapy was used. Cohort C exhibited the most significant increase in stage IV diagnoses (12.3%, 15.7%, 28.4%, respectively; p < 0.01). The median overall survival rates at the three-year follow-up demonstrated a decline over the years for stages II (97%, 98%, 57%, respectively; p < 0.05) and III (66%, 77%, 37%; p < 0.01). CONCLUSIONS There has been a worsening in the incidence of late-stage metastatic melanoma in Peru throughout the years, coupled with a significant decline in overall survival rates. This is underscored by the fact that half of the population lives in regions devoid of oncological access.

Technology innovation to reduce health inequality in skin diagnosis and to improve patient outcomes for people of color: a thematic literature review and future research agenda. Front Artif Intell 2024; 7:1394386.

Abstract
The health inequalities experienced by ethnic minorities have been a persistent and global phenomenon. The diagnosis of different types of skin conditions, e.g., melanoma, among people of color is one of such health domains where misdiagnosis can take place, potentially leading to life-threatening consequences. Although Caucasians are more likely to be diagnosed with melanoma, African Americans are four times more likely to present stage IV melanoma due to delayed diagnosis. It is essential to recognize that additional factors such as socioeconomic status and limited access to healthcare services can be contributing factors. African Americans are also 1.5 times more likely to die from melanoma than Caucasians, with 5-year survival rates for African Americans significantly lower than for Caucasians (72.2% vs. 89.6%). This is a complex problem compounded by several factors: ill-prepared medical practitioners, lack of awareness of melanoma and other skin conditions among people of colour, lack of information and medical resources for practitioners' continuous development, under-representation of people of colour in research, POC being a notoriously hard to reach group, and 'whitewashed' medical school curricula. Whilst digital technology can bring new hope for the reduction of health inequality, the deployment of artificial intelligence in healthcare carries risks that may amplify the health disparities experienced by people of color, whilst digital technology may provide a false sense of participation. For instance, Derm Assist, a skin diagnosis phone application which is under development, has already been criticized for relying on data from a limited number of people of color. This paper focuses on understanding the problem of misdiagnosing skin conditions in people of color and exploring the progress and innovations that have been experimented with, to pave the way to the possible application of big data analytics, artificial intelligence, and user-centred technology to reduce health inequalities among people of color.

Abstract
ABSTRACT In a retrospective analysis of biopsies from January 1, 2019 to December 31, 2020, at University Hospitals Cleveland Medical Center, we aimed to determine the frequency of dermatologic conditions biopsied in African Americans (AA). Given that AAs constitute 13.4% of the US population, understanding the skin disease profile within this significant demographic is crucial. From a total of 1701 biopsies collected from 1442 AA patients, benign neoplasms emerged as the most common diagnosis, accounting for 26.7%, predominantly in females. Notably, cutaneous T-cell lymphoma was the most frequently biopsied malignancy, whereas pigmentary disorders were the least common at 1.4%. The study highlighted the higher occurrence of squamous cell carcinoma compared with basal cell carcinoma in AA, contrasting trends in other racial demographics. Moreover, recognizing the unique presentations of skin disorders in different racial backgrounds is essential, especially because disparities have been reported in skin of color training among dermatology residency programs. Understanding these racial differences in skin diseases can assist clinicians in refining their diagnostic approach. Future research could further explore the potential gaps between clinical expectations and histologic findings, improving diagnostic accuracy.

Abstract
Importance Melanoma in Black individuals has an annual incidence of approximately 1 in 100 000 people. Most studies of melanoma in Black patients have used population databases, which lack important, precise clinical details. Objective To identify patient-level and tumor-level characteristics of melanoma in Black patients. Design, Setting, and Participants This case series included Black patients with melanoma at 2 tertiary care centers (University of Texas Southwestern [UTSW] Medical Center and Parkland Health), affiliated with a single institution, UTSW in Dallas, Texas. Self-reported Black patients with a histopathologic diagnosis of melanoma were identified between January 2006 and October 2022. Main Outcomes and Measures The main variables were demographics, clinical characteristics, personal and family medical history, immunosuppression history, comorbidities, histopathology reports, molecular/genetic studies, imaging reports, melanoma treatments and responses, time to progression, metastatic sites, and survival rates. Results A total of 48 Black patients with melanoma (median [range] age at diagnosis, 62 [23-86] years; 30 [63%] female) were included in the study. Of 40 primary cutaneous melanomas, 30 (75%) were located on acral skin, despite only 10 of 30 (33%) being histologically classified as acral lentiginous melanomas. Compared with those with acral disease, patients with nonacral cutaneous melanomas were more likely to be immunocompromised (4 of 10 [40%] vs 2 of 30 [7%]) or have a personal history of cancer (6 of 10 [60%] vs 5 of 30 [17%]), with all 3 patients with superficial spreading melanoma having a history of both. No patients had more than 1 confirmed primary melanoma. Overall, 13 Black patients (27%) with melanoma developed stage IV disease, of whom 12 died because of disease progression. Those diagnosed with advanced acral melanoma, mucosal/ocular melanoma, or melanoma of unknown primary lacked actionable sequence variations, were nonresponsive to immunotherapy, and had the poorest outcomes. No patients with nonacral cutaneous melanomas developed distant metastases or died of melanoma. Conclusions and Relevance This single-institution case series highlights several features of melanoma in Black patients that have not been captured in existing population-level registries, including precise anatomic sites, immune status, family and personal cancer history, and genetics. Multi-institutional registries would improve understanding of melanoma in Black patients.

Abstract
A systematic search was conducted on the PubMed database using the keywords "education," "melanoma," and "African Americans." The results were filtered to include studies published within the last decade that focused on melanoma diagnosis, risk, or outcomes. These selected studies included African Americans, non-Hispanic Black individuals, or those with darker skin tones and compared them with educational interventions or non-Hispanic White groups. The studies showed an overall positive impact of targeted educational initiatives on using sun-protective behaviors, health education, and self-efficacy related to melanoma. Notably, interventions proven to be effective for non-Hispanic White populations also demonstrated efficacy in other racial groups, including non-Hispanic Blacks. It was observed that non-Hispanic Blacks exhibited an overall reduced level of concern regarding melanoma, partly due to its lower incidence within this demographic. Furthermore, these studies focussed on the disparities in melanoma incidence and survival rates among different racial groups. Non-Hispanic Black individuals were found to have a higher incidence of melanoma and lower survival rates compared to non-Hispanic White individuals. Collectively, the studies evaluating melanoma educational interventions for darker skin tones yield promising results for improving melanoma prognosis in Black communities. They underscore the importance of addressing racial disparities in melanoma awareness, diagnosis, and treatments. These studies also highlighted the barriers to sun protection behaviors, such as cost, limited awareness, and misconceptions, particularly prevalent among ethnic communities and youth. The use of melanoma photographs specifically tailored to darker skin tones in outreach efforts to enhance identification, self-examination, and early detection should be considered to improve melanoma prognosis similar to the non-White population.

Abstract
PURPOSE To provide guidance to clinicians regarding the use of systemic therapy for melanoma. METHODS American Society of Clinical Oncology convened an Expert Panel and conducted an updated systematic review of the literature. RESULTS The updated review identified 21 additional randomized trials. UPDATED RECOMMENDATIONS Neoadjuvant pembrolizumab was newly recommended for patients with resectable stage IIIB to IV cutaneous melanoma. For patients with resected cutaneous melanoma, adjuvant nivolumab or pembrolizumab was newly recommended for stage IIB-C disease and adjuvant nivolumab plus ipilimumab was added as a potential option for stage IV disease. For patients with unresectable or metastatic cutaneous melanoma, nivolumab plus relatlimab was added as a potential option regardless of BRAF mutation status and nivolumab plus ipilimumab followed by nivolumab was preferred over BRAF/MEK inhibitor therapy. Talimogene laherparepvec is no longer recommended as an option for patients with BRAF wild-type disease who have progressed on anti-PD-1 therapy. Ipilimumab- and ipilimumab-containing regimens are no longer recommended for patients with BRAF-mutated disease after progression on other therapies.This full update incorporates the new recommendations for uveal melanoma published in the 2022 Rapid Recommendation Update.Additional information is available at www.asco.org/melanoma-guidelines.

Abstract
BACKGROUND Asian American and Pacific Islander (AAPI) melanoma patients have higher mortality than non-Hispanic White (NHW) patients. Treatment delays may contribute, but whether AAPI patients have longer time from diagnosis to definitive surgery (TTDS) is unknown. OBJECTIVES Investigate TTDS differences between AAPI and NHW melanoma patients. METHODS Retrospective review of AAPI and NHW melanoma patients in the National Cancer Database (NCD) (2004-2020). The association of race with TTDS was evaluated by multivariable logistic regression, controlling for sociodemographic characteristics. RESULTS Of 354,943 AAPI and NHW melanoma patients identified, 1155 (0.33%) were AAPI. AAPI patients had longer TTDS for stage I, II, and III melanoma (P < .05 for all). Adjusting for sociodemographic factors, AAPI patients had 1.5 times the odds of a TTDS between 61 and 90 days and twice the odds of a TTDS >90 days. Racial differences in TTDS persisted in Medicare and private insurance types. Uninsured AAPI patients had the longest TTDS (mean, 53.26 days), while those with private insurance had the shortest TTDS (mean, 34.92 days; P < .001 for both). LIMITATION AAPI patients comprised 0.33% of the sample. CONCLUSIONS AAPI melanoma patients have increased odds of treatment delays. Associated socioeconomic differences should inform efforts to reduce disparities in treatment and survival.

Abstract
Although there is a higher incidence of melanoma among non-Hispanic White individuals, melanoma is diagnosed at more advanced stages and associated with worse survival rates among individuals with skin of color (SOC). The proportions of melanoma subtypes differ across racial groups, with acral lentiginous melanoma and mucosal melanoma representing higher proportions of melanoma diagnoses in individuals with SOC compared to White individuals. The recognition of distinct differences in anatomic locations and dermatoscopic patterns may facilitate the appropriate differentiation of physiologic from pathologic pigmentation. The first article of this continuing medical education series will focus on the epidemiology and clinical presentation of melanoma in individuals with SOC, with the aim of improving early diagnoses and clinical outcomes.

Abstract
Melanoma is one of the most commonly diagnosed cancers in the Western world: third in Australia, fifth in the USA and sixth in the European Union. Predicting an individual's personal risk of developing melanoma may aid them in undertaking effective risk reduction measures. The objective of this study was to use the UK Biobank to predict the 10-year risk of melanoma using a newly developed polygenic risk score (PRS) and an existing clinical risk model. We developed the PRS using a matched case-control training dataset ( N = 16 434) in which age and sex were controlled by design. The combined risk score was developed using a cohort development dataset ( N = 54 799) and its performance was tested using a cohort testing dataset ( N = 54 798). Our PRS comprises 68 single-nucleotide polymorphisms and had an area under the receiver operating characteristic curve of 0.639 [95% confidence interval (CI) = 0.618-0.661]. In the cohort testing data, the hazard ratio per SD of the combined risk score was 1.332 (95% CI = 1.263-1.406). Harrell's C-index was 0.685 (95% CI = 0.654-0.715). Overall, the standardized incidence ratio was 1.193 (95% CI = 1.067-1.335). By combining a PRS and a clinical risk score, we have developed a risk prediction model that performs well in terms of discrimination and calibration. At an individual level, information on the 10-year risk of melanoma can motivate people to take risk-reduction action. At the population level, risk stratification can allow more effective population-level screening strategies to be implemented.

Abstract
Skin of colour or pigmented skin has unique characteristics: it has a higher eumelanin-to-pheomelanin ratio, more mature melanosomes, an increased amount of melanin distributed in the upper layers of the epidermis, and more efficient DNA repair compared with lighter skin. However, individuals with skin of colour are at a significant risk of skin damage caused by ultraviolet radiation, including the development of photodermatoses and photoageing changes such as uneven skin tone, and are predisposed to pigmentary disorders. In fact, one of the most common conditions leading to dermatology consultations by patients with skin of colour is photoexacerbated pigmentary disorders. Unfortunately, individuals with skin of colour may be less prone to engage in photoprotective measures, including the use of sunscreens. Physicians are also less likely to prescribe sunscreens for them. There is thus a clear need for better education on photodamage and for more efficient and suitable photoprotection in populations with skin of colour. However, this need has thus far only partially been met, and the development of sunscreen products designed to provide optimal photoprotection for people with skin of colour remains a challenge. Targeted sunscreens for individuals with skin of colour require optimal cosmetic appeal (leaving no white residue and not disrupting skin tone). They should include broad-spectrum [ultraviolet (UV)B/UVA] protection with high sun protection factor, as well as protection against long-wave UVA (UVA1) and visible light, as these wavelengths are capable of inducing or augmenting pigmentary disorders. They may also contain depigmenting agents for patients with pigmentary disorders.

Abstract
Melanoma in Black patients carries a poor prognosis. Due to its rarity, melanoma in this population has not been well characterized. This study evaluates survival predictors in Black patients with melanoma. This was a retrospective cohort study of Black patients with cutaneous melanoma from the National Cancer Database 2004-2018. Of the 2464 cases, melanoma was more common among females than males (57.1% vs. 42.9%, p < .001). Median Breslow depth was 1.8 mm (interquartile range 0.4-4.4). Lower extremities were the most common location (52.8%), followed by upper extremities (13.1%) along with otherwise specified/overlapping/other (13.1%), then by trunk (11.8%), and lastly head and neck (9.2%). Stage at diagnosis was I (30.7%), II (27.5%), III (24.1%), and IV (17.7%). Ulceration was observed in 41.4% of lesions. Acral lentiginous melanoma (ALM) was the most common specific histologic subtype (20.3%), followed by superficial spreading melanoma (9.4%). After adjusting for confounders, higher stages and primary site on the head and neck were the strongest independent predictors of worse overall survival. Melanoma in Black patients is most likely to appear on the lower extremities. A large portion (41.8%) presented with stage III or IV disease. ALM was the most common specific histologic subtype.

The Bias of Physicians and Lack of Education in Patients of Color With Melanoma as Causes of Increased Mortality: A Scoping Review. Cureus 2022; 14:e31669. [PMID: 36545166 PMCID: PMC9762426 DOI: 10.7759/cureus.31669] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Accepted: 11/19/2022] [Indexed: 11/21/2022] Open
Abstract
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.

An analysis of lactate dehydrogenase (LDH) levels in advanced stage IV melanoma of the skin: prognostic capabilities and demographic variability. Arch Dermatol Res 2022; 315:799-806. [PMID: 36318305 DOI: 10.1007/s00403-022-02425-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Revised: 08/01/2022] [Accepted: 10/13/2022] [Indexed: 11/07/2022]
Abstract
Despite its limitations, in part due to decreased specificity in advanced disease, serum lactate dehydrogenase (LDH) is one of few serum factors used in cancer staging. This study quantifies the predictive capabilities of LDH in stage IV melanoma of the skin and explores the validity of suggested demographic discrepancies which may exist in its use. The 1975-2017 Surveillance Epidemiology and End Results (SEER) database was queried for stage IV cutaneous melanoma cases. Demographic characteristics were compared between LDH groups using chi-square and t tests. Subsequent Cox multivariable regression was performed to assess survival differences. 334 cases of stage IV cutaneous melanoma (average age: 63.0 years) with measured serum LDH levels were identified. Of these patients, 150 (44.9%) had normal LDH, 112 (33.5%) had LDH < 1.5 × upper limit of normal (ULN), 57 (17.1%) had LDH 1.5-10 × ULN, and 15 (4.5%) had LDH > 10 × ULN. Lower incomes were associated with higher LDH; individuals with incomes < $50,000 had the greatest proportion of LDH 10 × ULN (19.2%; p = 0.0031). LDH > 10 × ULN also had the lowest proportion of White patients (p = 0.04). On Cox multivariable survival analysis, increasing LDH levels showed increased risk of death (LDH < 1.5 × ULN: HR = 2.05, p = 0.01; LDH 1.5-10 × ULN: HR = 1.46, p < 0.001; LDH > 10 × ULN: HR = 5.91, p < 0.001). This study reaffirms the utility of LDH as a significant predictor of mortality with incremental severity, suggesting possible use for mortality projections. We note that Black patients and those with lower incomes may be more likely to have an elevated LDH. Older age groups and presence of ulceration among patients with stage IV melanoma were also associated with a greater risk of mortality.

Abstract
Background Substantial evidence suggests that receptor tyrosine kinases (RTKs) are overexpressed in tumors; however, few studies have focused on the prognostic value of RTKs in melanoma. Objectives The objective of this study is to evaluate the association between overexpression of RTKs and survival in melanoma patients based on immunohistochemistry (IHC) analysis. Methods Our review is registered on PROSPERO (http://www.crd.york.ac.uk/PROSPERO), registration number CRD42021261460. Seven databases were searched, and data were extracted. We used IHC to measure the association between overexpression of RTKs and overall survival (OS), disease-free survival (DFS), progression-free survival (PFS), and clinicopathology in melanoma patients. Pooled analysis was conducted to assess the differences between Hazard Ratios along with 95% confidence intervals. Results Of 5,508 publications examined following the database search, 23 publications were included in this study, which included data from a total of 2,072 patients. Vascular endothelial growth factor receptor 2 (VEGF-R2) overexpression was associated with worse OS and DFS in melanoma. Furthermore, there was an association between OS and the expression of several RTKs, including epidermal growth factor receptor (EGFR), mesenchymal-epithelial transition factor (MET), vascular endothelial growth factor receptor 1 (VEGF-R1), and insulin-like growth factor 1 receptor (IGF-1R). There were no significant correlations between EGFR overexpression and worse DFS or PFS. EGFR overexpression was associated with worse OS cutaneous and nasal melanoma, but not uveal melanoma. However, MET overexpression was related to worse OS in both cutaneous and uveal melanoma. Furthermore, EGFR overexpression was associated with a worse OS in Europe compared to other geographic areas. Moreover, EGFR and MET overexpression showed significant prognostic value in patients with the cut-off “≥10% staining”. Conclusions Our findings build concrete evidence that overexpression of RTKs is associated with poor prognosis and clinicopathology in melanoma, highlighting RTK expression has the potential to inform individualized combination therapies and accurate prognostic evaluation.

Abstract
Despite decreased susceptibility, darker skin individuals who develop melanoma have worse survival. This disparity in melanoma mortality is the largest for any cancer, and partly driven by a lack of patient education materials targeted to darker skin populations in whom acral lentiginous melanoma (ALM) is the most common subtype. To address this communication disparity, the current study reports a multi-phase design process that leverages crowdsourcing and message testing to develop ALM-focused patient education materials for darker skin populations. Crowdsourced design was utilized to develop a pool of designs (phase 1), the pool was narrowed and thematically analyzed (phase 2), and select designs were evaluated via a message experiment (N = 1877). For darker skin populations, designs that depicted people enhanced knowledge of ALM through message memorability. The current study engages melanoma disparities by providing ALM patient education materials for darker skin populations vetted via a multi-phase process.

Abstract
Objectives. To investigate the histopathological characteristics of cutaneous melanoma in Isfahan from 2013 to 2018, according to histopathological subtype, lesions location, Clark level, and Breslow thickness. Methods. A descriptive, retrospective study in reports of Alzahra Hospital and Dr. Rajabi Pathology Laboratory in Isfahan. Results. In total, 45 patients were included in this study. The most prevalent histopathological subtype was acral lentiginous melanoma (48.89%), followed by lentigo maligna melanoma (17.78%), nodular melanoma (11.11%), and superficial spreading melanoma (8.89%). Most malignant lesions were on the foot and toes (31.1%) and face (24.4%). Tumor invasion level was mainly at Clark level IV (42.2%). Furthermore, the mean depth of tumor penetration (Breslow thickness) was 3.87 ± 3.35. Conclusions. Our study revealed the characteristics of melanoma in the Iranian population. Our results showed a similar trend with previous studies in the Asian population. Further investigations are needed to elucidate the role of ethnic and environmental risk factors for developing melanoma in different populations.

Abstract
BACKGROUND CONCORD-3 highlighted wide disparities in population-based 5-year net survival for cutaneous melanoma during 2000-2014. Clinical evidence suggests marked international differences in the proportion of lethal acral and nodular subtypes of cutaneous melanoma. OBJECTIVES We aimed to assess whether the differences in morphology may explain global variation in survival. METHODS Patients with melanoma were grouped into the following seven morphological categories: malignant melanoma, not otherwise specified (International Classification of Diseases for Oncology, third revision morphology code 8720), superficial spreading melanoma (8743), lentigo maligna melanoma (8742), nodular melanoma (8721), acral lentiginous melanoma (8744), desmoplastic melanoma (8745) and other morphologies (8722-8723, 8726-8727, 8730, 8740-8741, 8746, 8761, 8770-8774, 8780). We estimated net survival using the nonparametric Pohar Perme estimator, correcting for background mortality by single year of age, sex and calendar year in each country or region. All-ages survival estimates were standardized using the International Cancer Survival Standard weights. We fitted a flexible parametric model to estimate the effect of morphology on the hazard of death. RESULTS Worldwide, the proportion of nodular melanoma ranged between 7% and 13%. Acral lentiginous melanoma accounted for less than 2% of all registrations but was more common in Asia (6%) and Central and South America (7%). Overall, 36% of tumours were classified as superficial spreading melanoma. During 2010-2014, age-standardized 5-year net survival for superficial spreading melanoma was 95% or higher in Oceania, North America and most European countries, but was only 71% in Taiwan. Survival for acral lentiginous melanoma ranged between 66% and 95%. Nodular melanoma had the poorest prognosis in all countries. The multivariable analysis of data from registries with complete information on stage and morphology found that sex, age and stage at diagnosis only partially explain the higher risk of death for nodular and acral lentiginous subtypes. CONCLUSIONS This study provides the broadest picture of distribution and population-based survival trends for the main morphological subtypes of cutaneous melanoma in 59 countries. The poorer prognosis for nodular and acral lentiginous melanomas, more frequent in Asia and Latin America, suggests the need for health policies aimed at specific populations to improve awareness, early diagnosis and access to treatment. What is already known about this topic? The histopathological features of cutaneous melanoma vary markedly worldwide. The proportion of melanomas with the more aggressive acral lentiginous or nodular histological subtypes is higher in populations with predominantly dark skin than in populations with predominantly fair skin. What does this study add? We aimed to assess the extent to which these differences in morphology may explain international variation in survival when all histological subtypes are combined. This study provides, for the first time, international comparisons of population-based survival at 5 years for the main histological subtypes of melanoma for over 1.5 million adults diagnosed during 2000-2014. This study highlights the less favourable distribution of histological subtypes in Asia and Central and South America, and the poorer prognosis for nodular and acral lentiginous melanomas. We found that later stage at diagnosis does not fully explain the higher excess risk of death for nodular and acral lentiginous melanoma compared with superficial spreading melanoma.

Abstract
Objective Racial and ethnic health disparities affect the diagnosis and management of melanoma and nonmelanoma skin cancers, leading to deleterious outcomes. Non-Hispanic White patients make up the majority of skin cancers cases, yet racial and ethnic minorities have poorer prognoses and outcomes. The skin cancer literature is fragmented with regards to potential contributors to these healthcare disparities. In this article, we provide a comprehensive review of the skin cancer literature to briefly quantify racial and ethnic inequities, highlight contributing factors, and propose practical changes that can be made. Methods A PubMed search was completed to identify articles related to racial and ethnic health care disparities in the context of melanoma, basal cell carcinoma, squamous cell carcinoma, Merkel cell carcinoma, and dermatofibrosarcoma protuberans. Results Relative to non-Hispanic White patients, patients of racial and ethnic minorities have differing clinical presentations of skin cancers and genetic risk factors. Insurance, access to specialty care, cultural beliefs, and available educational resources further contribute to racial and ethnic disparities. Limitations We are limited to the level of detail provided in the existing literature, and at some times are unable to distinguish race of Hispanic populations. We also acknowledge that there are different nationalities grouped under these broad labels as well as multi-racial populations that may not be accounted for. Conclusion Awareness of and familiarization with innate factors and potentially more modifiable contributors can help inform efforts to close the observed gap in racial and ethnic inequities.

Abstract
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.

Abstract
BACKGROUND People of African, Asian, Hispanic or Latino, Pacific Islander, and Native Indian descent are considered people of color by the Skin of Color Society (SOCS). OBJECTIVES In this study, we assess incidence, risk factors, clinical characteristics, histopathology, treatment, and survival for skin malignancies in people of color as defined by the SOCS, by systematically reviewing the literature. METHODS An electronic literature search of the PubMed, EMBASE, and MEDLINE databases was performed. Articles published from 1 January 1990 through 12 December 2020 were included in the search. RESULTS We identified 2666 publications potentially meeting the study criteria. Titles and abstracts of these studies were reviewed and 2353 were excluded. The full text of 313 articles were evaluated and 251 were included in this review. CONCLUSION Differences in incidence, patterns, treatment, and survival exist among people of color for cutaneous malignancies. Further research and initiatives are needed to account for and mitigate these differences.

Abstract
Racial and ethnic disparities in dermatology negatively affect outcomes such as mortality and quality of life. Dermatologists and dermatologic surgeons should be familiar with disease-specific inequities that may influence their practice. The second article in this two-part continuing medical education series highlights gaps in frequency, clinical presentation, management, and outcomes by race and ethnicity. We review cutaneous malignancies including basal cell carcinoma, squamous cell carcinoma, melanoma, Merkel cell carcinoma, dermatofibrosarcoma protuberans, and cutaneous T cell lymphoma, and inflammatory disorders including atopic dermatitis, psoriasis, hidradenitis suppurativa, acne vulgaris, and rosacea.

Abstract
Rescue/recovery workers who responded to the World Trade Center (WTC) attacks were exposed to known/suspected carcinogens. Studies have identified a trend toward an elevated risk of cutaneous melanoma in this population; however, few found significant increases. Furthermore, temporal aspects of the association have not been investigated. A total of 44,540 non-Hispanic White workers from the WTC Combined Rescue/Recovery Cohort were studied between March 12, 2002 and December 31, 2015. Cancer data were obtained through linkages with 13 state registries. Poisson regression was used to estimate hazard ratios and 95% confidence intervals using the New York State population as the reference; change points in hazard ratios were estimated using profile likelihood. We observed 247 incident cases of melanoma. No increase in incidence was detected during 2002-2004. From 2005 to 2015, the hazard ratio was 1.34 (95% confidence interval = 1.18-1.52). A dose‒response relationship was observed by arrival time at the WTC site. Risk was elevated just over 3 years after the attacks. Whereas WTC-related exposures to UVR or other agents might have contributed to this result, exposures other than those at the WTC site, enhanced medical surveillance, and lack of a control group with a similar proportion of rescue/recovery workers cannot be discounted. Our results support continued study of this population for melanoma.

Abstract
Background Factors influencing the difference in the diagnosis and treatment of melanoma in racial minority groups are well-described in the literature and include atypical presentations and socioeconomic factors that impede access to care. Objective To characterize the differences in melanoma survival outcomes between non-Hispanic white patients and ethnic minority patients in North America. Methods We conducted searches of Embase via Ovid and MEDLINE via Ovid of studies published from 1989 to August 5, 2020. We included observational studies in North America which reported crude or effect estimate data on patient survival with cutaneous melanoma stratified by race. Results Forty-four studies met our inclusion criteria and were included in this systematic review. Pooled analysis revealed that black patients were at a significantly increased risk for overall mortality (HR 1.42, 95% CI, 1.25-1.60), as well as for melanoma-specific mortality (HR 1.27, 95% CI, 1.03-1.56). Pooled analyses using a representative study for each database yielded similar trends. Other ethnic minorities were also more likely report lower melanoma-specific survival compared to non-Hispanic white patients. Conclusion Our results support findings that melanoma patients of ethnic minorities, particularly black patients, experience worse health outcomes with regards to mortality. Overall survival and melanoma-specific survival are significantly decreased in black patients compared to non-Hispanic white patients. With the advent of more effective, contemporary treatments such as immunotherapy, our review identifies a gap in the literature investigating present-day or prospective data on melanoma outcomes, in order to characterize how current racial differences compare to findings from previous decades.

Abstract
Health disparities continue to exist in the United States, with the most significant differences in care occurring between racial groups. Racial health disparities are largely a result of the strong association between race and structural inequities, (differentials in the distribution of power, resources, opportunities). The use of case-based learning is common practice in pharmacy education, and the race of the patient who is the subject of the case is often included out of convention. In some cases, race is included to inform treatment based on guidelines developed from epidemiological and clinical studies that link race to disease by conferring biological significance to race categories. This continuing use of race and ethnicity to guide treatment contributes to racial health disparities and may further perpetuate existing provider implicit bias. This paper discusses the pedagogical approach of using patient cases and the convention, propriety, and implications of including race in patient cases, and guides pharmacy educators in how to use information on race.

Abstract
In humans, epidermal melanocytes are responsible for skin pigmentation, defence against ultraviolet radiation and the deadliest common skin cancer, melanoma. Although there is substantial overlap in melanocyte development pathways between different model organisms, species-dependent differences are frequent and the conservation of these processes in human skin remains unresolved. Here, we used a single-cell enrichment and RNA-sequencing pipeline to study human epidermal melanocytes directly from the skin, capturing transcriptomes across different anatomical sites, developmental age, sexes and multiple skin tones. We uncovered subpopulations of melanocytes that exhibit anatomical site-specific enrichment that occurs during gestation and persists through adulthood. The transcriptional signature of the volar-enriched subpopulation is retained in acral melanomas. Furthermore, we identified human melanocyte differentiation transcriptional programs that are distinct from gene signatures generated from model systems. Finally, we used these programs to define patterns of dedifferentiation that are predictive of melanoma prognosis and response to immune checkpoint inhibitor therapy.

Abstract
The purpose of this study was to use the Surveillance, Epidemiology, and End Results database to identify the incidence rate and risk factors for suicide death in patients with skin malignant melanoma (MM) in the USA. We screened cases of skin MM in the SEER database. The balance of covariates between the two groups was examined by the χ-test and Fisher's exact test. Logistic regression was used to identify independent risk factors for committing suicide. A propensity 1: 2 matched analysis was applied to minimize the risk of bias. In total, 103 500 patients with skin MM were included in the study, of whom 623 had died of suicide. The rate of suicide death did not differ significantly between different time intervals. In logistic regression before propensity score matching, age, being divorced, separated, or widowed, receiving radiation or chemotherapy, and the elapsed time since diagnosis were independently associated with an increased rate of suicide death. Only age (P < 0.001) and being in the first year after a diagnosis (P < 0.001) significantly increased the risk of suicide death after propensity score matching. In addition, after the propensity score matching, age was a risk factor for localized, regional, and unstaged, and being the first year after a diagnosis was only a risk factor for regional. It is important to identify and treat people at risk of suicide as early as possible. These results can help clinicians to understand suicidal patients and provide them with appropriate support.

Abstract
Our collective understanding of melanoma genomics has rapidly expanded in the past decade, bringing great promise to patients affected with the most severe and aggressive cases of melanoma. In this review, we present the practical clinical impact of genetics and genomics on modern melanoma diagnosis and treatment. Characterization of somatic driver mutations, which can be used to distinguish different subtypes of melanoma such as nonacral cutaneous melanoma (NACM), desmoplastic melanoma (DM), acral melanoma (AM), mucosal melanoma (MM) and uveal melanoma (UM), has led to the development of many targeted therapies against these tumours. Although targeted therapies exist for certain mutations, such as BRAF and KIT, other genotypes respond to newer-generation immune therapies such as immune checkpoint inhibitors. Epigenetics also plays a critical role in melanoma pathogenesis and drug resistance, holding promise for new treatment avenues. In this review, special attention is placed on clinical trials and translational research, especially novel genomic tests aimed to benefit patients on an individualized level in the current emerging era of personalized therapy.

Abstract
Several angiogenesis-dependent diseases, including age-related macular degeneration and infantile hemangioma, display differential prevalence among Black, as compared to White individuals. Although socioeconomic status and genetic architecture have been suggested as explaining these differences, we have recently shown that pigment production per se might be involved. For example, we have shown that the extracellular protein fibromodulin is a pro-angiogenic factor highly secreted by melanocytes in White but not Black individuals. Still, additional pigment-dependent angiogenic factors and their molecular mechanisms remain to be identified. Understanding the contribution of pigmentation to angiogenesis in health and disease is essential for precision medicine of angiogenesis-dependent diseases with racial disparity. Toward that goal, we compared the transcriptomes of Black and White individuals in three tissues with angiogenic activity, namely artery, whole blood, and skin. We identified several differentially expressed angiogenesis pathways, including artery morphogenesis, regulation of endothelial cell chemotaxis, and cellular response to vascular endothelial growth factor stimulus. We then demonstrated that the expression of key genes in these pathways is directly modulated by the degree of pigmentation. We further identified the precise pigment production pathway controlling the expression of these genes, namely melanocortin 1 receptor (MC1R) signaling. These results demonstrate pigment-mediated regulation of angiogenesis-related pathways and their driver genes across human tissues.

Abstract
BACKGROUND Melanoma-specific outcomes for Black patients are worse when compared to non-Hispanic white (NHW) patients. We sought to evaluate whether acral lentiginous melanoma, seen more commonly in Black patients, was associated with racial disparities in outcomes METHODS: The National Cancer Database was analyzed for major subtypes of stage I-IV melanoma diagnosed from 2004 to 2016. The association between Black race and (Siegel et al., Jan) 1 acral melanoma diagnosis and (Bradford et al., Apr) 2 receipt of major amputation for surgical management of melanoma was evaluated using multivariable logistic regression. RESULTS 251,864 patients were included (1453 Black). Black patients had increased odds of acral melanoma (odds ratio [OR] = 27.6, 95% CI]: 24.4, 31.2) compared to NHW patients. Black patients still had higher odds ratios of major amputation across all stages after adjusting for acral histology and other potential confounders CONCLUSIONS: Increased prevalence of acral melanoma in Black patients does not fully account for increased receipt of major amputation.

Abstract
BACKGROUND Dermoscopy is undoubtedly a useful tool to improve diagnostic accuracy and minimize the number of unnecessary biopsies. However, much of the literature on dermoscopy focuses on findings in lighter-skin phototypes, leaving potential gaps of knowledge regarding its use in skin of color (SoC). As the clinical applications of dermoscopy continue to increase, understanding dermoscopic patterns in SoC is imperative. OBJECTIVE This review discusses the literature on dermoscopic findings of neoplasms in SoC, highlighting unique and characteristic dermoscopic features. METHODS A literature review was performed using the PubMed database. Case reports, case series, case-control studies, and systematic reviews were included. RESULTS A total of 8326 studies were identified based on the selected search terms, and 41 were included in this review based on relevance. CONCLUSION There are specific dermoscopic characteristics in SoC for benign nevi, acral lentiginous melanoma, ethnic melanonychia, and dermatofibroma; however, there is a lack of published data about specific features of cutaneous melanoma, subungual melanoma, pigmented basal cell carcinoma, and pigmented squamous cell carcinoma in SoC. Because pigmented basal cell carcinoma, pigmented squamous cell carcinoma, ethnic melanonychia, and acral lentiginous melanoma are diagnosed at later stages in this population, it is important to understand their dermoscopic features. Further descriptive studies are needed to better characterize unique dermoscopic features in neoplasms in SoC.

Abstract
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.

Trends in short-term survival from distant-stage cutaneous melanoma in the United States, 2001-2013 (CONCORD-3). JNCI Cancer Spectr 2021; 4:pkaa078. [PMID: 33409455 PMCID: PMC7771008 DOI: 10.1093/jncics/pkaa078] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2020] [Revised: 07/13/2020] [Accepted: 08/19/2020] [Indexed: 11/24/2022] Open
Abstract
Background Survival from metastatic cutaneous melanoma is substantially lower than for localized disease. Treatments for metastatic melanoma have been limited, but remarkable clinical improvements have been reported in clinical trials in the last decade. We described the characteristics of US patients diagnosed with cutaneous melanoma during 2001-2013 and assessed trends in short-term survival for distant-stage disease. Methods Trends in 1-year net survival were estimated using the Pohar Perme estimator, controlling for background mortality with life tables of all-cause mortality rates by county of residence, single year of age, sex, and race for each year 2001-2013. We fitted a flexible parametric survival model on the log-hazard scale to estimate the effect of race on the hazard of death because of melanoma and estimated 1-year net survival by race. Results Only 4.4% of the 425 915 melanomas were diagnosed at a distant stage, cases diagnosed at a distant stage are more commonly men, older patients, and African Americans. Age-standardized, 1-year net survival for distant-stage disease was stable at approximately 43% during 2001-2010. From 2010 onward, survival improved rapidly, reaching 58.9% (95% confidence interval = 56.6% to 61.2%) for patients diagnosed in 2013. Younger patients experienced the largest improvement. Survival for distant-stage disease increased in both Blacks and Whites but was consistently lower in Blacks. Conclusions One-year survival for distant-stage melanoma improved during 2001-2013, particularly in younger patients and those diagnosed since 2010. This improvement may be a consequence of the introduction of immune-checkpoint-inhibitors and other targeted treatments for metastatic and unresectable disease. Persistent survival inequalities exist between Blacks and Whites, suggesting differential access to treatment.

Abstract
BACKGROUND Dermatologic surgery services are largely absent in Africa and in Afro-Caribbean counties. In the USA, studies of people of African ancestry have demonstrated health care gaps, but there are no data for Africa nor a Afro-Caribbean country. Dermatology surgery has been largely absent from global health because there are few data to demonstrate the need. We sought to determine skin cancer tumor types, and local knowledge and perception in an Afro-Caribbean country. OBJECTIVE We sought to determine whether there exist knowledge gaps and whether a dermatology surgery medical missions program would improve the health of Afro-Caribbean people. METHODS First, we conducted a survey of knowledge and behaviors related to skin cancer. Second, we analyzed the number and types of tumors treated during a multi-year surgical dermatology project. RESULTS In the survey, 62% did not know what melanoma was. Eighty-one percent did not think skin cancer is preventable. Of 163 surgical specimens, 64 were malignancies with 91% related to UV exposure. CONCLUSION There is a need for a skin cancer treatment and education program in a country of mostly African-ancestry people.

Abstract
PURPOSE To provide guidance to clinicians regarding the use of systemic therapy for melanoma. METHODS ASCO convened an Expert Panel and conducted a systematic review of the literature. RESULTS A systematic review, one meta-analysis, and 34 additional randomized trials were identified. The published studies included a wide range of systemic therapies in cutaneous and noncutaneous melanoma. RECOMMENDATIONS In the adjuvant setting, nivolumab or pembrolizumab should be offered to patients with resected stage IIIA/B/C/D BRAF wild-type cutaneous melanoma, while either of those two agents or the combination of dabrafenib and trametinib should be offered in BRAF-mutant disease. No recommendation could be made for or against the use of neoadjuvant therapy in cutaneous melanoma. In the unresectable/metastatic setting, ipilimumab plus nivolumab, nivolumab alone, or pembrolizumab alone should be offered to patients with BRAF wild-type cutaneous melanoma, while those three regimens or combination BRAF/MEK inhibitor therapy with dabrafenib/trametinib, encorafenib/binimetinib, or vemurafenib/cobimetinib should be offered in BRAF-mutant disease. Patients with mucosal melanoma may be offered the same therapies recommended for cutaneous melanoma. No recommendation could be made for or against specific therapy for uveal melanoma.

Abstract
OBJECTIVE The relationship between the clinicopathological and sociodemographics characteristics of acral melanomas diagnosed at the Hospital do Servidor Público Estadual de São Paulo was analyzed and traced between 1997 and 2016. METHODS An observational, descriptive, and retrospective study of patients diagnosed with acral melanoma was performed at Hospital do Servidor Público Estadual de São Paulo. Sociodemographic and clinicopathological characteristics were collected and analyzed. RESULTS Forty-five patients with acral melanomas were found during the evaluation period. Thirty-one were females, and 14 were males (68.89% and 31.3%, respectively). Most of the cases were invasive (88.37%), and the predominant histological subtype was the acral lentiginous (91.11%). The plantar region was the most prevalent (64.44%). The median Breslow index was 3 mm, and there was a tendency towards greater severity in male patients. CONCLUSIONS Acral site melanomas are detected diagnosed when they reach more advanced stages, which leads to a worse prognosis for patients. Late detection assumes even greater importance in highly mixed and black populations, such as the Brazilian population.

Abstract
Importance Obesity is a cancer risk factor, and bariatric surgery in patients with obesity is associated with reduced cancer risk. However, evidence of an association among obesity, bariatric surgery, and skin cancer, including melanoma, is limited. Objective To investigate the association of bariatric surgery with skin cancer (squamous cell carcinoma and melanoma) and melanoma incidence. Design, Setting, and Participants This nonrandomized controlled trial, the Swedish Obese Subjects (SOS) study, is ongoing at 25 surgical departments and 480 primary health care centers in Sweden and was designed to examine outcomes after bariatric surgery. The study included 2007 patients with obesity who underwent bariatric surgery and 2040 contemporaneously matched controls who received conventional obesity treatment. Patients were enrolled between September 1, 1987, and January 31, 2001. Data analysis was performed from June 29, 2018, to November 22, 2018. Interventions Patients in the surgery group underwent gastric bypass (n = 266), banding (n = 376), or vertical banded gastroplasty (n = 1365). The control group (n = 2040) received the customary treatment for obesity at their primary health care centers. Main Outcomes and Measures The SOS study was cross-linked to the Swedish National Cancer Registry, the Cause of Death Registry, and the Registry of the Total Population for data on cancer incidence, death, and emigration. Results The study included 4047 participants (mean [SD] age, 47.9 [6.1] years; 2867 [70.8%] female). Information on cancer events was available for 4042 patients. The study found that bariatric surgery was associated with a markedly reduced risk of melanoma (adjusted subhazard ratio, 0.43; 95% CI, 0.21-0.87; P = .02; median follow-up, 18.1 years) and risk of skin cancer in general (adjusted subhazard ratio, 0.59; 95% CI, 0.35-0.99; P = .047). The skin cancer risk reduction was not associated with baseline body mass index or weight; insulin, glucose, lipid, and creatinine levels; diabetes; blood pressure; alcohol intake; or smoking. Conclusions and Relevance The results of this study suggest that bariatric surgery in individuals with obesity is associated with a reduced risk of skin cancer, including melanoma. Trial Registration ClinicalTrials.gov identifier: NCT01479452.

Abstract
Several recent studies have reported a considerably higher overall survival (OS) rate in females in various geographic regions This study further investigates the characteristics of melanoma that contribute to OS of women residing in the United States. Chi-square, Kaplan-Meier, and Cox regression models were used to analyze differences in demographics, treatment, and survival of invasive cutaneous melanoma in men and women diagnosed from 2004 to 2016 in the National cancer database. In 316 966 patients met inclusion criteria. Men had a significantly higher median age of diagnosis at 61 years (interquartile range or IQR: 51-72) in comparison to women where the median age of diagnosis was 55 years (IQR: 43-68) (P < .0001). The most common primary site for men was the trunk (35.5%), whereas the lower extremities were the most common primary site for women (30.3%). Women had a higher 5 year (82.6%) and 10 year (73.1%) OS compared to 5 year and 10 year OS of 72.2% and 58.7%, respectively, in men (P < .0001). When adjusting for confounders, female gender was independently associated with improved OS (ref: male HR = 0.791; 95% confidence interval 0.773-0.809; P < .0001). Overall, we conclude that female gender is an independent favorable prognostic factor for melanoma survival.

Background Randomized comparisons have demonstrated survival benefit of adjuvant immunotherapy in node-positive melanoma patients but have limited power to determine if this benefit persists across various demographic factors. Materials & methods We assessed the impact of demographic factors on the survival benefit of adjuvant immunotherapy in a database of 38,189 node-positive melanoma patients using the Kaplan-Meier method and Cox proportional hazards models. Results All assessed demographic factors other than race significantly impacted survival of node-positive melanoma patients in univariate analysis. In multivariable analysis, only the age group interacted with immunotherapy. Conclusion Analysis of this large database of unselected node-positive melanoma patients demonstrated a positive survival benefit of immunotherapy across all demographic factors assessed and the impact was greater for patients 65 years of age and older.

Abstract
Background Vemurafenib is a selective BRAF inhibitor with significant early effects in melanoma, but resistance will develop with the duration of treatment. Therefore, overcoming vemurafenib resistance can effectively improve the survival rate of melanoma. The transcriptional activity of TCF4 is necessary to maintain the malignant phenotype of cancer cells. However, the effect of TCF4 on melanoma sensitivity to vemurafenib and the underlying mechanism is unclear. Methods Vemurafenib-resistant A375 (A375/Vem) and SK-Mel-28 (SK-Mel-28/Vem) cells were constructed by administering increasing concentrations of vemurafenib, and the expression of TCF4 was examined in parent and vemurafenib-resistant cells. TCF4 loss-function cells models were established in A375/Vem and SK-Mel-28/Vem cells, respectively. Cell survival, clone formation, and cell apoptosis were assessed. The downstream target gene of TCF4 was verified by chromatin immunoprecipitation. Finally, the effect of TCF4 on melanoma cells glycolysis was investigated and were performed. Results TCF4 expression was increased in vemurafenib-resistant melanoma cells, and knocking down TCF4 could promote the sensitivity of melanoma cells to vemurafenib. Mechanism investigation revealed that TCF4 could interact with GLUT3 and silencing TCF4 could inhibit GLUT3 expression. In addition, overexpression of GLUT3 reversed the growth and glycolysis of tumor cells that were inhibited by TCF4 knockdown. Conclusion Our study demonstrates that TCF4 downregulation sensitizes melanoma cells to vemurafenib through inhibiting GLUT3-mediated glycolysis. These findings support TCF4 as an oncogene and provide new mechanism by which TCF4 confers chemotherapy resistance in melanoma.

Abstract
Background Longer time from diagnosis to definitive surgery (TTDS) is associated with increased melanoma-specific mortality. Although black patients present with later-stage melanoma and have worse survival than non-Hispanic white patients, the association between race and TTDS is unknown. Objective To investigate racial differences in time to melanoma treatment. Methods Retrospective review of the National Cancer Database (2004-2015). Multivariable logistic regression was used to evaluate the association of race with TTDS, controlling for sociodemographic/disease characteristics. Results Of the 233,982 patients with melanoma identified, 1221 (0.52%) were black. Black patients had longer TTDS for stage I to III melanoma (P < .001) and time to immunotherapy (P = .01), but not for TTDS for stage IV melanoma or time to chemotherapy (P > .05 for both). When sociodemographic characteristics were controlled for, black patients had over twice the odds of having a TTDS between 41 and 60 days, over 3 times the odds of having a TTDS between 61 and 90 days, and over 5 times the odds of having a TTDS over 90 days. Racial differences in TTDS persisted within each insurance type. Patients with Medicaid had the longest TTDS (mean, 60.4 days), and those with private insurance had the shortest TTDS (mean, 44.6 days; P < .001 for both). Conclusions Targeted approaches to improve TTDS for black patients are integral in reducing racial disparities in melanoma outcomes.

Abstract
BACKGROUND Acral lentiginous melanoma (ALM) occurs on the palms, soles and subungual surface and has poor prognosis. It is uncommon in the Caucasian population and has remained unreported in East-Central Europe. OBJECTIVES Our aim was to collect data from East-Central Europe by analysing the demographic and clinicopathologic features of patients with ALM and comparing data with the reports in literature. METHODS We conducted a single-centre, retrospective review between 1976 and 2016 at one of the largest melanoma referral centres in Hungary. RESULTS We identified 176 patients with ALM (3.83%) from 4593 patients with melanoma (mean age: 66.2 years). The tumours were mainly located on the lower extremities (88.63%). The mean Breslow tumour thickness was 3.861 mm, 37.50% of the tumours were thicker than 4.00 mm, and 71.6% exhibited microscopic ulceration. Nearly one-third of the patients underwent sentinel lymph node (SLN) biopsy, and 60.3% of the biopsies were positive for metastasis. The positive SLN status was associated with significantly thick tumours and reduced survival. Patients with ALM had 5- and 10-year overall survival rates of 60.5% and 41.6%, respectively. The mean delay in diagnosis was 18 months after the discovery of skin tumours. In multivariate analyses, age, tumour thickness and distant metastasis were independent risk factors for poor survival (P < 0.001). CONCLUSIONS Our study, which is the first single-centre report in East-Central Europe focusing on ALM, confirms that patient and tumour characteristics and prognostic factors are similar with previous literature data involving Caucasians; however, tumour thickness and survival suggest even worse prognosis.

Abstract
This study aimed to establish the clinicopathological characteristics of patients with melanoma and its association with BRAF gene mutations. The pathology reports and paraffin-embedded tumor samples from 47 women and 30 men with melanoma, with an average age of diagnosis of 60 years, were reviewed at the Hospital Federico Lleras Acosta of Ibague, between 2010 and 2016. The presence of V600E mutation at the exon 15 of BRAF gene, was analyzed in these tumoral samples by Sanger sequencing and visual inspection of the electropherograms. We also studied the clinicopathological variables with X2, t-Student and the Kaplan Meier index. Most of the lesions were located in the lower limbs (46.6%). The most frequent subtype was Acral Lentiginous Melanoma (41.8%). Most lesions were of poor prognosis: Breslow depth greater than 4.1 mm (52.7%), ulceration (61.4%) and medium or high mitotic rate (> 30 %). The V600E mutation was identified in five patients with large, deep and ulcerated tumors, four of them had less than four years of survival. In conclusion, there was a higher frequency of melanoma in women, V600E BRAF mutation was present in patients with advanced disease (high Breslow index) and, the probability of five-year survival was less than 40%.
