Ju X, Rokohl AC, Li X, Guo Y, Yao K, Fan W, Heindl LM. A UV-related risk analysis in ophthalmic malignancies: Increased UV exposure may cause ocular malignancies. ADVANCES IN OPHTHALMOLOGY PRACTICE AND RESEARCH 2024; 4:98-105. [PMID: 38707995 PMCID: PMC11066588 DOI: 10.1016/j.aopr.2024.04.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 03/08/2024] [Accepted: 04/02/2024] [Indexed: 05/07/2024]
Abstract
Purpose To explore the role of ultraviolet radiation (UVR) in the occurrence and development of various ocular malignancies. Methods In this article, we retrieved ocular malignancy data from the Global Cancer Observatory (GCO) and performed correlation analysis with the global UV index and sunshine duration. We searched for associated studies using the following databases: Embase, Pubmed, Cochrane Library, and Google Scholar. We conducted the literature by searching the Mesh terms denoting an exposure of interest ("UV radiation", "ultraviolet rays", and "ocular malignancies", All studies included are published until December 30, 2023 without language restrictions. Results The mechanisms and epidemiological statistics of UVR on the onset and progression of eyelid malignancies are the most studied and clear. The role of UVR in conjunctival melanoma is similar to that in eyelid melanoma. The relationship between uveal melanoma and UVR is controversial, however, it may have at least a certain impact on its prognosis. UVR causes ocular surface squamous neoplasia by further activating HPV infection. Conclusions UVR is a decisive risk factor for ocular malignancies, but the incidence of ultraviolet-induced tumors is also affected by many other factors. A correct and comprehensive understanding of the mechanisms of UVR in the pathogenesis of ocular malignant tumors can provide patients with more effective and selective immune regulation strategies.

The Role of Sex and Gender in Dermatology - From Pathogenesis to Clinical Implications. J Cutan Med Surg 2023; 27:NP1-NP36. [PMID: 37401812 PMCID: PMC10486181 DOI: 10.1177/12034754231177582] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Revised: 03/29/2023] [Accepted: 04/09/2023] [Indexed: 07/05/2023]
Abstract
BACKGROUND Sex and gender have increasingly been recognized as significant risk factors for many diseases, including dermatological conditions. Historically, sex and gender have often been grouped together as a single risk factor in the scientific literature. However, both may have a distinct impact on disease incidence, prevalence, clinical presentation, severity, therapeutic response, and associated psychological distress. OBJECTIVES AND PROJECT DESCRIPTION The mechanisms that underlie differences in skin diseases between males, females, men, and women remain largely unknown. The specific objectives of this review paper are:To highlight the biological differences between males and females (sex), as well as the sociocultural differences between men and women (gender) and how they impact the integumentary system.To perform a literature review to identify important sex- and gender-related epidemiological and clinical differences for various skin conditions belonging to a range of disease categories and to discuss possible biological and sociocultural factors that could explain the observed differences.To discuss dermatological skin conditions and gender-affirming treatments within the transgender community, a population of individuals who have a gender identity which is different than the gender identity they were assigned at birth. FUTURE IMPACT With the rising number of individuals that identify as non-binary or transgender within our increasingly diverse communities, it is imperative to recognize gender identity, gender, and sex as distinct entities. By doing so, clinicians will be able to better risk-stratify their patients and select treatments that are most aligned with their values. To our knowledge, very few studies have separated sex and gender as two distinct risk factors within the dermatology literature. Our article also has the potential to help guide future prevention strategies that are patient-tailored rather than using a universal approach.

Serum Vitamin D Levels Explored in the Latvian Cohort of Patients with Basal Cell Carcinoma Linked to the Sonic Hedgehog and Vitamin D Binding Protein Cutaneous Tissue Indices. Nutrients 2022; 14:nu14163359. [PMID: 36014865 PMCID: PMC9413259 DOI: 10.3390/nu14163359] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2022] [Revised: 08/07/2022] [Accepted: 08/08/2022] [Indexed: 11/16/2022] Open
Abstract
Ultraviolet radiation is known as one of the major contributors to skin malignancies, including basal cell carcinoma (BCC), which is the most common type of skin cancer. It is a heterogeneous tumor, which presents with various types that are stratified into low- and high-risk tumors. Sunlight is important for overall health and vitamin D synthesis in the skin, whereas deviations from the optimal level of vitamin D are shown to be associated with the risk of the development of BCC. The accumulating evidence suggests the ability of vitamin D to antagonize the Sonic Hedgehog (SHH) signaling, the key tumor pathway, and play a protective role in the development of BCC. Additionally, a vitamin D binding protein (DBP) is shown to be implicated in the complex regulation of vitamin D. Here, we aimed to explore serum vitamin D in patients with different primary and recurrent BCC of the head and neck and investigate cutaneous DBP and SHH indices, confirmed immunohistochemically in these subjects. According to the results, 94.9% of the Latvian cohort of BCC patients were found to be deficient in vitamin D. No significant differences in serum vitamin D levels were found between genders, primary and recurrent tumors, and different types of BCC. Serum vitamin D was inversely associated with tumor size. Susceptible male individuals with low blood vitamin D levels were recognized at risk of developing aggressive and recurrent BCC confirmed by the use of hierarchical clustering analysis. In smaller tumors with a favorable course, such as superficial and nodular BCC, the association between high DBP and low SHH tissue expression was found, providing supportive evidence of the existence of a link between vitamin D, proteins involved in its metabolism, as exemplified by the DBP and SHH signaling pathway. The assumption of a deficiency in the protective effect of vitamin D in patients with high-risk BCCs was proposed in low DBP and high SHH tissue indices. New extensions to existing knowledge and characterization of the BCC signaling pathways and their cross-talk with vitamin D are warranted when searching for a preferential effect of vitamin D on skin cancer.

Abstract
Non-melanoma skin cancer (NMSC) is the most common malignancy seen in Caucasians and includes basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). The incidence of NMSC is showing an increasing trend which is attributed to the increased use of sunbeds, recreational sun exposure, aging population, and partly to improved screening and reporting. Ultraviolet (UV) radiation plays the most crucial role in the pathogenesis of both BCC and SCC by inducing DNA damage and mutagenic photoproducts. Other risk factors are fair skin, old age, genetic predisposition, immunosuppression, ionizing radiation, organic chemicals, and HPV infection. The role of genomic instability, genetic mutations/aberrations, and host immunity has been fairly illustrated in several studies. This chapter aims to discuss these aspects of NMSC in detail.

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
BACKGROUND Basal cell carcinoma (BCC) is the most common skin cancer. Incidence is largely unknown because of incomplete, or lack of, registration in most countries. OBJECTIVES To assess current incidence rates and recent trends for BCC in the Swedish population. METHODS Patient- and tumour-related features of all histologically confirmed BCC tumours diagnosed in Sweden from 2004 to 2017 were extracted from the population-based Swedish BCC Registry. Incidence rates were standardized to the 2013 European Standard Population and trends were analysed using Poisson regression models. RESULTS Age-standardized person-based incidence rate of BCC in Sweden in 2017 was 405/100 000, rising from 308/100 000 in 2004, corresponding to an annual relative increase of 1.8% (women, 2.1%; men, 1.4%). Incidence was highest in the elderly and the most common tumour site was the head and neck. In 2017, the most common BCC subtypes were nodular and micronodular/infiltrative BCC (each 31%). Incidence of aggressive BCC subtypes increased faster than other subtypes. CONCLUSIONS BCC incidence rates in Sweden are relatively high and increasing. The increasing trends were more pronounced in women and for aggressive BCC subtypes.

Abstract
Background Sex or gender disparity in skin cancer has been documented for a long time at the population level. UV radiation (UVR) is a common environmental risk for all three major types of skin cancer: cutaneous melanoma (CM), basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC). The underlying mechanism for sex disparity has been largely attributed to sex‐differentiated behaviour patterns related to UVR. Non‐UVR factors such as intrinsic physiological differences have been suggested but remain understudied. Aims, Materials and Methods This review summarizes and compares the known sex differences in three skin cancer types with regard to body site distribution and age influence. Results We found a similar age‐dependent sex difference pattern in CM and BCC. Specifically, CM and BCC tend to show higher incidence in young women and old men, with a switching age around menopause. The switching age suggests involvement of sex hormones, which has shown controversial influence on skin cancers at epidemiological level. Literatures regarding sex hormone receptors for oestrogen, androgen and progesterone are summarized for potential explanations at molecular level. Discussion Overall, more and more evidence suggests non‐UVR factors such as sex hormones play critical roles in skin cancer (especially CM and BCC), yet solid population and molecular evidence are required. Incidences of skin cancer are increasing which suggests limited effect for the current UVR‐avoidance prevention methods. Conclusion Fully understanding the causes of sex disparities in incidence is necessary for developing a comprehensive prevention strategy.

Abstract
Non-melanoma skin cancers (NMSCs) are the most common malignancies diagnosed in Caucasian populations. Basal cell carcinoma (BCC) is the most frequent skin cancer, followed by squamous cell carcinoma (SCC). Unfortunately, most European cancer registries do not record individual types of NMSC. To evaluate the incidence of primary BCCs and SCCs regarding age, sex, tumour site and tumour subtype to determine trends in epidemiology of both cancers. Retrospective analysis of BCCs and SCCs diagnosed and treated across seven sites in Poland from 1999 to 2019. We recorded 13,913 NMSCs occurring in 10,083 patients. BCC represented 85.2% of all cases. SCC patients were older than BCC patients (77.1 ± 11.3 years vs. 70.1 ± 12.3 years, p < 0.01). The nodular subtype was the most common subtype of BCC, followed by the superficial and infiltrative subtypes. The superficial BCC subtype was more common on photoprotected areas (p < 0.01), whereas the nodular BCC subtype occurred on the face (p < 0.01). The high-risk SCC subtypes were more common on face compared to low-risk SCC subtypes (p < 0.01). BCC and SCC are common malignancies developing at various ages and anatomical sites. These data underline the need for better registration policies regarding NMSC in order to improve prevention and treatment strategies for these tumours.

Abstract
Malignant melanoma and nonmelanoma skin cancers (NMSC), which include basal cell carcinoma and squamous cell carcinoma, account for 40% of all neoplasms in white patients, making these cancers the most common malignancy in the United States. Given the large number of NMSC cases in white patients, there is a correspondingly large body of literature addressing various aspects of epidemiology, pathogenesis, and treatment. The incidence of both malignant melanoma and NMSC is well established and remains significantly lower in patients with skin of color (SoC) when compared with white patients. Although there is a lower incidence of skin cancer in SoC, there is often a poorer prognosis among this group. There is even more limited data focusing on women of color, making an accurate determination of incidence and mortality difficult. This gender disparity causes decreased skin cancer awareness and index of suspicion among patients and providers, hindering appropriate evaluation and care. Therefore, there is a need for an increased understanding of skin cancer in women of color. In the traditional sense, SoC refers to people of African, Asian, Native American, Middle Eastern, and Hispanic backgrounds. Patients in these ethnic groups have richly pigmented skin that is usually categorized as Fitzpatrick types III through VI and thus have notable differences in skin disease and presentation compared with fair-skinned individuals. We present this review of skin cancer in women of color to give a reasonably comprehensive representation of the literature to advance our understanding and knowledge in this unique population.

Abstract
The role of microRNAs (miRNAs/miRs) in governing the progression of cutaneous squamous cell carcinoma (cSCC) has been the focus of recent studies. However, the functional role of miR-451a in cSCC growth remains poorly understood. Therefore, the present study aimed to determine the expression levels of miR-451a in cSCC cell lines and the involvement of miR-451a in cSCC progression. The results revealed that the expression levels of miR-451a were downregulated in cSCC tissues and cell lines, and that this subsequently upregulated 3-phosphoinositide-dependent protein kinase-1 (PDPK1) expression levels. PDPK1 was validated as a direct target of miR-451a in cSCC using bioinformatics software Starbase, dual-luciferase reporter gene assays and western blotting. Additionally, CCK-8, EdU and Transwell assays, as well as flow cytometry and Hoechst 3325 staining, were performed to assess the malignant aggressiveness of cSCC cells. Overexpression of miR-451a was demonstrated to impair the proliferation, migration, invasion and epithelial-mesenchymal transition (EMT), and promoted apoptosis in cSCC cells by interacting with PDPK1, possibly by direct targeting. Furthermore, the western blotting results indicated that miR-451a overexpression may block the PI3K/AKT signaling pathway by interacting with PDPK1. In conclusion, the findings of the present study suggested that miR-451a may prevent the proliferation, migration, invasion and EMT of cSCC cells through the PDPK1-mediated PI3K/AKT signaling pathway, which may offer potential therapeutic targets for the treatment of cSCC.

Abstract
BACKGROUND Keratinocyte cancer (KC) patients benefit from early diagnosis. We describe here the anatomy of head/neck KCs to help guide screening efforts. OBJECTIVE To examine lesion frequency and anatomic distribution of head and neck KC. METHODS This retrospective cohort study of 4,770 consecutive pathology reports, 1998 to 2015, analyzes 5,463 head and neck KCs (3,664 basal cell carcinoma [BCC], 1,259 squamous cell carcinoma [SCC], and 540 SCC in situ) from 3,581 patients. RESULTS Basal cell carcinoma relative tumor density (RTD) was highest on the nose; SCC RTD was highest on the cheek. Basal cell carcinoma-to-SCC ratio was highest on eyelid and lowest on scalp. Temple, ear, and neck SCC predominated in men; nose and cheek SCC in women. Scalp, temple, and ear BCC showed male predominance, while cheek, nose, and chin predominated in women. Left-sided ear SCC in situ and BCC were more common than right-sided ear lesions. CONCLUSION This study demonstrates gender- and laterality-specific differences that comport with patterns of solar exposure.

Abstract
BACKGROUND Basal cell carcinoma (BCC) is the commonest cancer affecting white-skinned individuals, and worldwide incidence is increasing. Although rarely fatal, BCC is associated with significant morbidity and costs. First-line treatment is usually surgical excision, but alternatives are available. New published studies and the development of non-surgical treatments meant an update of our Cochrane Review (first published in 2003, and previously updated in 2007) was timely. OBJECTIVES To assess the effects of interventions for BCC in immunocompetent adults. SEARCH METHODS We updated our searches of the following databases to November 2019: Cochrane Skin Group Specialised Register, CENTRAL, MEDLINE, Embase, CINAHL, and LILACS. SELECTION CRITERIA Randomised controlled trials (RCTs) of interventions for BCC in immunocompetent adults with histologically-proven, primary BCC. Eligible comparators were placebo, active treatment, other treatments, or no treatment. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. Primary outcome measures were recurrence at three years and five years (measured clinically) (we included recurrence data outside of these time points if there was no measurement at three or five years) and participant- and observer-rated good/excellent cosmetic outcome. Secondary outcomes included pain during and after treatment, early treatment failure within six months, and adverse effects (AEs). We used GRADE to assess evidence certainty for each outcome. MAIN RESULTS We included 52 RCTs (26 new) involving 6690 participants (median 89) in this update. All studies recruited from secondary care outpatient clinics. More males than females were included. Study duration ranged from six weeks to 10 years (average 13 months). Most studies (48/52) included only low-risk BCC (superficial (sBCC) and nodular (nBCC) histological subtypes). The majority of studies were at low or unclear risk of bias for most domains. Twenty-two studies were industry-funded: commercial sponsors conducted most of the studies assessing imiquimod, and just under half of the photodynamic therapy (PDT) studies. Overall, surgical interventions have the lowest recurrence rates. For high-risk facial BCC (high-risk histological subtype or located in the facial 'H-zone' or both), there may be slightly fewer recurrences with Mohs micrographic surgery (MMS) compared to surgical excision (SE) at three years (1.9% versus 2.9%, respectively) (risk ratio (RR) 0.64, 95% confidence interval (CI) 0.16 to 2.64; 1 study, 331 participants; low-certainty evidence) and at five years (3.2% versus 5.2%, respectively) (RR 0.61, 95% CI 0.18 to 2.04; 1 study, 259 participants; low-certainty evidence). However, the 95% CI also includes the possibility of increased risk of recurrence and no difference between treatments. There may be little to no difference regarding improvement of cosmetic outcomes between MMS and SE, judged by participants and observers 18 months post-operatively (one study; low-certainty evidence); however, no raw data were available for this outcome. When comparing imiquimod and SE for nBCC or sBCC at low-risk sites, imiquimod probably results in more recurrences than SE at three years (16.4% versus 1.6%, respectively) (RR 10.30, 95% CI 3.22 to 32.94; 1 study, 401 participants; moderate-certainty evidence) and five years (17.5% versus 2.3%, respectively) (RR 7.73, 95% CI 2.81 to 21.3; 1 study, 383 participants; moderate-certainty evidence). There may be little to no difference in the number of participant-rated good/excellent cosmetic outcomes (RR 1.00, 95% CI 0.94 to 1.06; 1 study, 326 participants; low-certainty evidence). However, imiquimod may result in greater numbers of good/excellent cosmetic outcomes compared to SE when observer-rated (60.6% versus 35.6%, respectively) (RR 1.70, 95% CI 1.35 to 2.15; 1 study, 344 participants; low-certainty evidence). Both cosmetic outcomes were measured at three years. Based on one study of 347 participants with high- and low-risk primary BCC of the face, radiotherapy may result in more recurrences compared to SE under frozen section margin control at three years (5.2% versus 0%, respectively) (RR 19.11, 95% CI 1.12 to 325.78; low-certainty evidence) and at four years (6.4% versus 0.6%, respectively) (RR 11.06, 95% CI 1.44 to 84.77; low-certainty evidence). Radiotherapy probably results in a smaller number of good participant- (RR 0.76, 95% CI 0.63 to 0.91; 50.3% versus 66.1%, respectively) or observer-rated (RR 0.48, 95% CI 0.37 to 0.62; 28.9% versus 60.3%, respectively) good/excellent cosmetic outcomes compared to SE, when measured at four years, where dyspigmentation and telangiectasia can occur (both moderate-certainty evidence). Methyl-aminolevulinate (MAL)-PDT may result in more recurrences compared to SE at three years (36.4% versus 0%, respectively) (RR 26.47, 95% CI 1.63 to 429.92; 1 study; 68 participants with low-risk nBCC in the head and neck area; low-certainty evidence). There were no useable data for measurement at five years. MAL-PDT probably results in greater numbers of participant- (RR 1.18, 95% CI 1.09 to 1.27; 97.3% versus 82.5%) or observer-rated (RR 1.87, 95% CI 1.54 to 2.26; 87.1% versus 46.6%) good/excellent cosmetic outcomes at one year compared to SE (2 studies, 309 participants with low-risk nBCC and sBCC; moderate-certainty evidence). Based on moderate-certainty evidence (single low-risk sBCC), imiquimod probably results in fewer recurrences at three years compared to MAL-PDT (22.8% versus 51.6%, respectively) (RR 0.44, 95% CI 0.32 to 0.62; 277 participants) and five years (28.6% versus 68.6%, respectively) (RR 0.42, 95% CI 0.31 to 0.57; 228 participants). There is probably little to no difference in numbers of observer-rated good/excellent cosmetic outcomes at one year (RR 0.98, 95% CI 0.84 to 1.16; 370 participants). Participant-rated cosmetic outcomes were not measured for this comparison. AEs with surgical interventions include wound infections, graft necrosis and post-operative bleeding. Local AEs such as itching, weeping, pain and redness occur frequently with non-surgical interventions. Treatment-related AEs resulting in study modification or withdrawal occurred with imiquimod and MAL-PDT. AUTHORS' CONCLUSIONS Surgical interventions have the lowest recurrence rates, and there may be slightly fewer recurrences with MMS over SE for high-risk facial primary BCC (low-certainty evidence). Non-surgical treatments, when used for low-risk BCC, are less effective than surgical treatments, but recurrence rates are acceptable and cosmetic outcomes are probably superior. Of the non-surgical treatments, imiquimod has the best evidence to support its efficacy. Overall, evidence certainty was low to moderate. Priorities for future research include core outcome measures and studies with longer-term follow-up.

Abstract
OBJECTIVES To assess the prevalence of melanoma and non-melanoma skin cancer for patients attended King Khalid University Hospital, Riyadh, Saudi Arabia. We are also assessing the most common category of skin cancer to be encountered among those patients. Methods: The authors conducted a retrospective study including all patients (Saudi and non-Saudi) who attended King Khalid University Hospital (KKUH) at the period of (2007-2018). Data were collected from archives of Pathology Department at KKUH and categorized into: melanoma skin cancer (MSC), non-melanoma skin cancer (NMSC), which included: basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), pre-neoplastic lesions, and non-neoplastic skin lesions. Results: A total of 111 patients were reported to have skin cancer out of 9828 cases, which had other skin pathology. Majority of cases were basal cell carcinoma with a total number of 76 (68.5%) of all cases. 18 patients (16.2%) were diagnosed with MSC. The remaining 17 patients (15.3%) were diagnosed with squamous cell carcinoma. Conclusion: Skin cancer prevalence and incidence is increasing worldwide. In our study, BCC was the most common type of skin cancer to be reported in our institute, which is similar to the majority of other international studies.

Abstract
BACKGROUND An epidemic of basal cell carcinoma (BCC) has led to a significant healthcare burden in white populations. OBJECTIVES To provide an update on incidence rates and tumour burden in an unselected, geographically isolated population that is exposed to a low level of ultraviolet radiation. METHODS This was a whole-population study using a cancer registry containing records of all cases of BCC in 1981-2017. We assessed BCC incidence according to age, residence and multiplicity and assessed trends using join-point analysis. Age-standardized and age-specific incidence rates were calculated along with cumulative and lifetime risks. RESULTS During the study period, the age-standardized incidence rates increased from 25·7 to 59·9 for men, and from 22·2 to 83·1 for women (per 100 000). Compared with the single-tumour burden, the total tumour burden in the population was 1·72 times higher when accounting for multiplicity. At the beginning of the study period, the world-standardized rates in men and women were similar, but by the end of the study period the rates were 39% higher in women (83·1 per 100 000, 95% confidence interval 77·9-88·3) than in men (59·9 per 100 000, 95% confidence interval 55·6-64·2). This increase was most prominent in women on sites that are normally not exposed to ultraviolet radiation in Iceland: the trunk and legs. CONCLUSIONS This is the only reported population in which the incidence of BCC is significantly higher in women than in men. The period of notable increase in BCC lesions correlates with the period of an increase in tanning beds and travel popularity. The high multiplicity rates suggest that the total tumour burden worldwide might be higher than previously thought. What is already known about this topic? Basal cell carcinoma (BCC) is becoming an increasing healthcare burden worldwide, especially in white populations. Recent population studies have reported a rapid increase in incidence among younger individuals, especially women. What does this study add? Iceland is the only reported population in which the incidence of BCC is significantly higher in women than in men, and there does not seem to be a clear relationship between latitude and BCC incidence in Europe. Men might be comparatively protected in the northern low-ultraviolet environment, with tanning beds and travel abroad likely playing important roles in the observed incidence increase, especially in women. The high multiplicity rates suggest that the total tumour burden worldwide might be higher than previously thought. Linked Comment: Pandeya. Br J Dermatol 2020; 183:799-800.

Abstract
BACKGROUND Skin cancer is common after solid organ transplantation, but few have investigated it after lung transplant (LTx). OBJECTIVE We assessed incidence and predictors of non-melanoma skin cancer (NMSC) post-LTx. METHODS We studied patients who underwent LTx at our center from 2012 to 2015. RESULTS Of 287 patients, mean age was 59.6 ± 11 years, 170 (59.2%) were men, and 231 (80.5%) were white. Seventy-six (26.5%) developed NMSC over a median follow-up of 32 months (IQR, 23-45). Of those with NMSC, 37% developed subsequent skin cancer of the same type. Independent predictors of decreased odds of NMSC and squamous cell carcinoma (SCC) were non-white race (P = .002; P = .003) and body mass index >30 kg/m2 compared with underweight patients (P = .001, P = .009). Patients with skin cancer pre-LTx had higher risk of post-LTx skin cancer (P = .02). Voriconazole use ≥100 days was associated with increased risk of SCC (P = .03), but not increased risk of basal cell carcinoma. Out of 76, 4 (5.3%) died from skin cancer. LIMITATIONS Retrospective, single-center study. CONCLUSION Squamous cell carcinoma risk post-LTx may increase with prolonged voriconazole use in white patients with pre-LTx history of skin cancer, whereas excess body weight may be protective from NMSC. Regular pre- and post-LTx skin cancer screenings and guidelines are warranted.

Abstract
Basal cell carcinoma (BCC) is more frequent among females <40 years old; however, it affects preferentially older males (>60 years old). In order to contribute to the study of the still largely unknown mechanisms that underlie this peculiar sex-dependent shift, we compared the kinetics of the increase of the age-specific BCC incidence rates (R) as a function of age in males and females. Studies reporting sex-stratified R were found using a PubMed search and male to female age-specific incidence rate ratios (RR) were calculated for each age-class as reported in each study and assigned to the mean of the corresponding age periods. Trends in age were assessed with Kendall's τ test and relationships between two variables by inverse variance method-weighed Loess and linear regression analysis. Sixteen data sets were eligible and confirmed a significant shift in the male to female ratio (Kendall's τ = 0.530; P < 0.001). Moreover, the slope parameter b = 1.205 (SE = 0.014) of the best fit (r 2 = 0.980) regression line resulting by plotting male vs. female age-specific incidence rates predicts a statistically significant (P = 0.001), constant, about 20% faster increase of R in males of all ages. Similar relationship are also evident for cutaneous squamous cell and Merkel cell carcinoma and, even more intriguing, for sums of all cancers (excluding BCC and SCC) in many different registries. In conclusion, females are probably born with an inherently higher risk to develop BCC; however, also with a much slower increase rate of this risk as a function of age. Notably this observation seems to be not a BCC peculiarity. Because of its high incidence coupled with moderate morbidity and extremely low mortality rates, BCC may serve as a valuable, single-tumor paradigm to reproach the complex mechanisms that underline the interaction of age and sex in the pathogenesis of human malignancies.

Noninvasive evaluation of hemodynamics and light scattering property during two-stage mouse cutaneous carcinogenesis based on multispectral diffuse reflectance images at isosbestic wavelengths of hemoglobin. JOURNAL OF BIOMEDICAL OPTICS 2019; 24:1-11. [PMID: 30635994 PMCID: PMC6975185 DOI: 10.1117/1.jbo.24.3.031020] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/02/2018] [Accepted: 12/11/2018] [Indexed: 05/06/2023]
Abstract
We investigate a multispectral imaging method to evaluate spatiotemporal changes in both cutaneous hemoglobin concentration and light scattering parameter in mouse skin through diffuse reflectance spectroscopy using the reflectance images acquired at isosbestic wavelengths of hemoglobin (420, 450, 500, and 585 nm). In the proposed approach, Monte Carlo simulation-based empirical formulas are introduced to extract the scattering power b representing the wavelength dependence of light scattering spectrum of skin tissue, as well as the total hemoglobin concentration Cth in dermal vasculatures. The use of isosbestic wavelengths of hemoglobin enables the values of Cth and b to be estimated independently of the oxygenation of hemoglobin. Experiments using in vivo mice two-stage chemical carcinogenesis model are performed to confirm the feasibility of the proposed method for evaluating the changes in cutaneous vasculatures and tissue morphology during tumor initiation, promotion, and progression processes. The experimental results reveal that the changes in scattering power b of back skin are significantly reduced and followed by the increase in total hemoglobin concentration Cth in the carcinogenesis mice group, which indicates morphological changes in skin tissue such as edema and cell swelling caused by tumor promotion and successive angiogenesis along with tumor progression. The results suggest that the potential of the present method to detect cutaneous carcinogenesis in an early stage and monitor physiological changes during promotion and progression process of nonmelanoma tumors.

Abstract
BACKGROUND The incidence of basal cell carcinoma (BCC) in younger individuals has increased in recent decades. However, the characteristics of BCCs in this population, especially in Ibero-Latin American countries, have not been completely defined. OBJECTIVE To describe the demographic, clinical, and histopathological characteristics of BCCs in patients younger than 40 treated with Mohs Micrographic Surgery (MMS). MATERIALS AND METHODS A multicenter, retrospective study conducted between January 2009 and December 2014, in five Ibero-American countries, included biopsy-proven BCCs in patients younger than 40 that were treated with MMS. Demographic, clinical, histopathological, and surgical characteristics were described. RESULTS The study included 301 tumors in 241 patients, of whom 61% were female. The most common Fitzpatrick phototype was III. The most common histological subtypes were nodular (37.5%) and infiltrative (18.9%). Perineural invasion was encountered in 1.7%, and tumor clearance was achieved in 87.4% within two stages of MMS. CONCLUSIONS This is the first Ibero-Latin American transnational study describing the characteristics of BCCs in young patients treated with MMS. Despite darker skin phototypes in this population, BCCs can occur in early ages and may present with aggressive features. Therefore, MMS may be considered an appropriate first-line treatment option in this population.

Abstract
Ultraviolet radiation is an important etiologic factor in skin cancer and a better understanding of how solar stimulated light (SSL) affects signal transduction pathways in human skin which is needed in further understanding activated networks that could be targeted for skin cancer prevention. We utilized Reverse Phase Protein Microarray Analysis (RPPA), a powerful technology that allows for broad-scale and quantitative measurement of the activation/phosphorylation state of hundreds of key signaling proteins and protein pathways in sun-protected skin after an acute dose of two minimal erythema dose (MED) of SSL. RPPA analysis was used to map the altered cell signaling networks resulting from acute doses of solar simulated radiation (SSL). To that end, we exposed sun-protected skin in volunteers to acute doses of two MED of SSL and collected biopsies pre-SSL and post-SSL irradiation. Frozen biopsies were subjected to laser capture microdissection (LCM) and then assessed by RPPA. The activation/phosphorylation or total levels of 128 key signaling proteins and drug targets were selected for statistical analysis. Coordinate network-based analysis was performed on specific signaling pathways that included the PI3k/Akt/mTOR and Ras/Raf/MEK/ERK pathways. Overall, we found early and sustained activation of the PI3K-AKT-mTOR and MAPK pathways. Cell death and apoptosis-related proteins were activated at 5 and 24 h. Ultimately, expression profile patterns of phosphorylated proteins in the epidermal growth factor receptor(EGFR), AKT, mTOR, and other relevant pathways may be used to determine pharmacodynamic activity of new and selective topical chemoprevention agents administered in a test area exposed to SSL to determine drug-induced attenuation or reversal of skin carcinogenesis pathways. Skin exposure to ultraviolet radiation leads to the activation of proteins involved in carcinogenic pathways. Janine Einspahr and Clara Curiel-Lewandrowski of the Arizona Cancer Center and colleagues in the US exposed normally ultraviolet protected skin of 12 individuals to two times the dose of solar-simulated light needed to induce redness. Skin biopsies were taken before and after exposure and 128 proteins known to be involved in key cancer signaling pathways were examined using ‘reverse phase protein microarray analysis’. They found early and sustained activation of multiple signaling pathways, in addition to activation of cell death and apoptosis-related proteins. The study may serve as a model for investigating the pathways involved in chronic or ultraviolet-induced carcinogenesis, which may ultimately lead to the development of targeted therapies to attenuate or reverse skin cancer pathways.

Phosphoinositide 3-Kinase-Dependent Signalling Pathways in Cutaneous Squamous Cell Carcinomas. Cancers (Basel) 2017; 9:cancers9070086. [PMID: 28696382 PMCID: PMC5532622 DOI: 10.3390/cancers9070086] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2017] [Revised: 06/26/2017] [Accepted: 07/03/2017] [Indexed: 01/11/2023] Open
Abstract
Cutaneous squamous cell carcinoma (cSCC) derives from keratinocytes in the epidermis and accounts for 15–20% of all cutaneous malignancies. Although it is usually curable by surgery, 5% of these tumours metastasise leading to poor prognosis mostly because of a lack of therapies and validated biomarkers. As the incidence rate is rising worldwide it has become increasingly important to better understand the mechanisms involved in cSCC development and progression in order to develop therapeutic strategies. Here we discuss some of the evidence indicating that activation of phosphoinositide 3-kinases (PI3Ks)-dependent signalling pathways (in particular the PI3Ks targets Akt and mTOR) has a key role in cSCC. We further discuss available data suggesting that inhibition of these pathways can be beneficial to counteract the disease. With the growing number of different inhibitors currently available, it would be important to further investigate the specific contribution of distinct components of the PI3Ks/Akt/mTOR pathways in order to identify the most promising molecular targets and the best strategy to inhibit cSCC.

Abstract
BACKGROUND Skin cancer remains the most prevalent type of cancer in the United States, and its burden on the health care system remains substantial. Standard treatments such as cryosurgery, electrodessication and curettage, topical and photodynamic therapies, and surgical excision including Mohs micrographic surgery are not without inherent morbidity, including risk of bleeding, infection, and scar. OBJECTIVE Lasers may be an alternative for treatment of nonmelanoma skin cancer, and this paper reviews this therapeutic option. METHODS A comprehensive search in the Cochrane Library, MEDLINE, and PUBMED databases was performed to identify relevant literature investigating the role of laser therapy in the treatment of nonmelanoma skin cancer. RESULTS New literature regarding laser treatment of nonmelanoma skin cancer is emerging, demonstrating promising clinical outcomes. The greatest efficacy has been seen with vascular-selective and ablative lasers in the treatment of basal cell carcinomas. Some success has been reported for laser treatment of squamous cell carcinoma, but data are less convincing. In summary, laser therapy offers an alternative treatment option for nonmelanoma skin cancer; however, its clinical efficacy is variable and, at this time, remains less than currently accepted standards of care. CONCLUSION Further studies are needed to optimize parameters, determine maximum efficacy, and provide long-term follow-up.

Abstract
BACKGROUND Squamous cell carcinoma (SCC) is considered the most frequent skin cancer in Black people. Its incidence is not known in the Afro-Caribbean population. OBJECTIVE To assess the incidence of SCC in Guadeloupe, the largest island of the Lesser Antilles (405 000 inhabitants, mostly Black people of African and European descent). The second objective was to characterize clinical and histological patterns of SCC occurring in the Afro-Caribbean community. METHODS This retrospective study was conducted over an 11-year period (2000-2010). Data regarding 723 histological confirmed cases of SCC identified using the three Guadeloupean pathology laboratories' computerized databases were retrieved from the records of 551 patients. Private practice dermatologists and general practitioners were contacted to obtain any missing data. RESULTS The annual age-adjusted incidence of SCC was 15 per 100.000 residents in Guadeloupe. In the Afro-Caribbean community, SCC had a greater size (i.e. 2.8 ± 2.8 cm vs. 1.5 ± 1.0 cm, P < 0.001), was more often located on the anogenital area (i.e. 48/79-60.8% vs. 14/320-4.4%, P < 0.001) in association with an underlying dermatosis due to HPV infection (15/71-21.1% vs. 3/366, 0.8%, P < 0.001) and led more frequently to metastasis (13/84-15.5% vs. 10/366-2.7%, P < 0.001) and/or fatal evolution (11/83-13.3% vs. 7/365-1.9%, P < 0.001). CONCLUSIONS The results of this original study, which first estimated the incidence of SCC in West Indies, suggest that anogenital examination should be routinely performed in skin cancer screening of Afro-Caribbean people to detect the presence of SCC at an early stage. IMPLICATION FOR PRACTICE Squamous cell carcinoma is the most frequent skin cancer in Black people. Its incidence is not known in the Afro-Caribbean population. In Guadeloupe, the largest island of the Lesser Antilles, the annual age-adjusted incidence of SCC was estimated to be 15.0 per 100 000 residents, 95% CI:[13.8; 16.2]. In the Guadeloupean Afro-Caribbean community, SCC seems to more frequently occur in the anogenital area, due to HPV infection. These results support to include a routine genital urinary examination in the skin cancer screening of people of Afro-Caribbean descent.

Abstract
Cutaneous squamous cell carcinoma (SCC) is a common cancer in white populations and its disease burden is often substantially underestimated. SCC occurs more often in men than women and increases dramatically with age; those affected often develop multiple primaries over time, which increases the burden. The main external cause is solar ultraviolet radiation (UVR), with immunosuppression being the other established risk factor, shown by the high SCC rates in organ transplant recipients. Sunbed use and certain genetic disorders and medical conditions are also associated with SCC, while associations with human papillomavirus infection and high bodyweight are not established. The presence of actinic keratoses (AKs) on sun-damaged skin is one of the strongest predictors of SCC in unaffected people and a very small proportion of AKs are SCC precursors, although the true rate of malignant transformation of AKs is unknown. The mainstay of SCC prevention is protection of the skin from undue sun exposure by use of clothing cover and sunscreen during summer or in sunny places. Educational, behavioural and multicomponent interventions directed at individuals ranging from parents of newborns, to school children and adolescents, to outdoor workers, have repeatedly been shown to be effective in improving sun-protective behaviours. Health policies can facilitate SCC prevention by setting standards for relevant behaviours to reduce UVR exposure, for example, by legislated restriction of the tanning industry. Skin cancer prevention initiatives are generally highly cost-effective and public investment should be encouraged to control the growing public health problems caused by SCC.

Abstract
Background: Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), collectively referred to as nonmelanoma skin cancer (NMSC), cause significant morbidity and generate a substantial cost to the health care system. Canadian data on the incidence of NMSC are lacking. Objective: To study the incidence and characteristics of NMSC in New Brunswick, Canada (population 729,498 people in 2001), by using the Provincial Cancer Registry. Method: Data were obtained from 1992 to 2001 from the New Brunswick Provincial Cancer Registry, to which reporting of all cancers is mandatory. Multiple tumors of a given histologic type are recorded only once in the registry per individual per lifetime. A descriptive analysis of incidence rates of BCC and invasive SCC of the skin was performed in relation to gender, age, and anatomic location. The main outcome measures were the age- and sex-specific incidence rates of BCC and SCC. Age standardization was performed using the Canadian, US, and world standard populations. Results: When adjusted to the world standard population, the age-standardized incidence rates (ASIRs) per 100,000 population for BCC from 1992 through 2001 were 87 for males and 68 for females. For invasive SCC, the ASIRs per 100,000 population were 34 for males and 16 for females. There was an increasing incidence trend for both BCC and invasive SCC over the 10-year study period, with minimal change in the incidence of SCC in women. The overall ratio of BCC to invasive SCC in the population was 2.8 to 1. The approximate lifetime probabilities of developing BCC and invasive SCC were 13% and 5%, respectively. Conclusions: The incidence of NMSC in the province of New Brunswick is similar to that reported from 1973 through 1987 in the province of British Columbia, higher than those reported in most parts of Europe, and lower than all published rates in the United States and Australia. Owing to the inability of the registry to account for tumor multiplicity, the actual annual number of all NMSC lesions in this population is likely much higher.

Abstract
Non-melanoma skin cancer represents one-third of all malignancies and its incidence is expected to rise until the year 2040. Cutaneous squamous cell carcinoma (cSCC) represents 20 % of all non-melanoma skin cancer and is a deadly threat owing to its ability to metastasize to any organ in the body. Therefore, a better understanding of cSCC is essential to strengthen preventative measures and curable treatment options. Currently, research demonstrates that cSCC is diagnosed at a rate of 15-35 per 100,000 people and is expected to increase 2-4 % per year. With respect to metastatic cSCC, this disease is more common in men; people over the age of 75 years; and inhabitants of the south and mid-west USA. In 2010, the American Joint Committee on Cancer updated the Cancer Staging Manual's primary tumor designation to now include high-risk factors; however, factors such as immunosuppression and tumor recurrence were not included. Other staging systems such as Brigham and Women's Hospital have allowed for increased stratification of cSCC. High-risk cSCC is defined as a cSCC that is staged as N0, extends beyond basement membrane, and has high-risk features associated with sub-clinical metastasis. High-risk features are depth of invasion (>2 mm), poor histological differentiation, high-risk anatomic location (face, ear, pre/post auricular, genitalia, hands, and feet), perineural involvement, recurrence, multiple cSCC tumors, and immunosuppression. Epidermal growth factor receptor and nuclear active IκB kinase (IKK) expression are also predictive of metastatic capabilities. Clinically, the initial lesions of a cSCC tumor can present as a painless plaque-like or verrucous tumor that can ultimately progress to being large, necrotic, and infected. Tumors can also present with paresthesias or lymphadenopathy depending on the location involved. With respect to prognosis, metastatic cSCC is lethal, with several large studies demonstrating a mortality rate of >70 %. Therefore, treatment of metastatic cSCC is difficult and depends on the location involved and extent of metastasis. Treatment options include surgery, radiation therapy, chemotherapy, and any combination of the above. Surgery alone can be used for metastatic cSCC treatment, but is not as effective as surgery in conjunction with radiation therapy. Radiation therapy has some success as a monotherapy in low-risk or cosmetically sensitive areas such as the external ear, eyelid or nose. According to the 2013 National Comprehensive Cancer Network Guidelines, cisplatin as a single agent or combined with 5-fluorouracil hold the strongest support for the treatment of metastatic cSCC; however, the supporting evidence is inconsistent and a curative chemotherapeutic approach is still lacking. Epidermal growth factor receptor inhibitors are a newer class of agents being used in metastatic cSCC and hold some promise as a therapy for this disease. Other areas of interest in finding curative treatments for metastatic cSCC include p53, hypermethylation of specific genes, chromatin remodeling genes, and the RAS/RTK/PI3K pathway. This review addresses the epidemiology, staging, risk factors, clinical presentation, management, and new trends in the treatment of high-risk and metastatic cSCC.

Abstract
Background: The efficacy and safety of efalizumab have been evaluated in multiple clinical trials. ObjectiveThe purpose of this review is to provide an overview of the safety profile of efalizumab during the clinical trials. Methods: Twelve-week data from four placebo-controlled trials were pooled and analyzed. Data from patients receiving 13—60 weeks of efalizumab therapy were pooled to evaluate longer-term safety. Results: The most common adverse events were mild to moderate, self-limiting, flulike symptoms that were most frequent following the first two efalizumab doses; by the third dose the incidence was comparable to placebo. Serious adverse events were observed in 2.2% and 1.7% of efalizumab- and placebo-treated patients, respectively. Nonserious adverse events leading to withdrawal were infrequent and similar to placebo (2.8% vs 1.8%). There does not appear to be increased risk of end-organ toxicity, infection, or malignancy in efalizumab-treated patients. Conclusion: Efalizumab was well tolerated, with a favorable safety profile.

Abstract
Background: Basal cell carcinoma (BCC) is extremely common, and its incidence continues to rise. Objective: This review presents the literature pertaining to the epidemiology, pathogenesis, and risk factors associated with BCC. Conclusions: The risk of developing BCC depends on both genetic predisposition and exposure to risk. Fair-skinned people account for the overwhelming majority of patients, beyond what would be expected by skin phototype alone. Damage to multiple lines of defense appears to be necessary for cancer development and spread. This damage distorts the concerted effort of deoxyribonucleic acid (DNA) repair, immunosurveillance, and cellular growth regulation to protect against malignant progression. Ultraviolet light exposure is the most critical modifiable factor determining early expression and frequency of BCC development.

Abstract
BACKGROUND Non-melanoma skin cancer (NMSC) is the most common type of cancer among Caucasians, however, few data exist on its incidence. Because of a sheer volume of these tumours, NMSC is often not systematically registered. OBJECTIVE To describe and analyse the incidence of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) in Belgium. METHODS Incidence data of BCC and SCC, including multiple primary skin tumours in the same patient, were extracted from the Belgian Cancer Registry from 2004 to 2012 (predominantly coming from pathology notifications). Belgian legislation makes cancer registration compulsory for oncological care programmes and for all pathological anatomy laboratories. RESULTS Between 2004 and 2012, 113 254 BCC and 33 153 SCC cases were reported in Belgium. A total of 130 339 patients had 146 407 tumours. Approximately, 10% of the patients (12 759 patients) had multiple tumours. The world age-standardised incidence rate (WSR) for BCC increased from 36.9 in 2004 to 98.4 per 100 000 person years in 2012 for males and from 34.2 in 2004 to 102.0 in 2012 for females. For SCC, the WSR increased from 14.9 in 2004 to 24.7 in 2012 for males and from 6.8 in 2004 to 13.5 in 2012 for females. CONCLUSIONS From 2004 to 2012, the incidence of BCC and SCC markedly rose in Belgium, as also seen worldwide. Known causes are increased sun exposure caused by changed sunlight-related behaviour (increased outdoor activities and holidays, use of tanning beds and changes in clothing style), ageing and improved registration. Because of their high and increasing incidence, these cancers will have major implications on healthcare planning and preventive measures. Therefore, we recommend compulsory registration, whenever is possible, of BCC and SCC, although it is an ambitious objective, especially in countries with a high burden of these tumours and in countries where registration is currently unavailable.

Abstract
Cutaneous malignancies make up the majority of periocular tumors diagnosed and treated by ophthalmologists. In this review, we examine literature regarding ethnic and socioeconomic disparities in incidence and clinical outcomes of the three most common cutaneous periocular tumors: basal cell carcinoma, squamous cell carcinoma, and melanoma. In all three tumor types, the literature shows an increased incidence among two groups: those with lightly pigmented skin and those of higher socioeconomic status. While incidence is high in these groups, clinical outcomes for these patients tend to be good. Those with lower socioeconomic status and ethnic minorities, on the other hand, have a low incidence but are more likely to have poor clinical outcomes. These disparities are likely the result of both biologic and behavioral differences between patients and could provide opportunities for intervention to change risk perception and improve outcomes.

Abstract
BACKGROUND Cutaneous squamous cell carcinoma (cSCC) is the second most common cancer in the United States. Cutaneous squamous cell carcinoma has an estimated incidence of more than 700,000 new cases per year and a 5% risk of metastasis. OBJECTIVE To provide clinicians with guidelines for the management of cSCC based on evidence from a comprehensive literature review and consensus among the authors. MATERIALS AND METHODS The authors conducted an extensive review of the medical literature on treatment methods for cSCC, taking into consideration cure rates, recurrence and metastatic rates, aesthetic and functional outcomes, and cost effectiveness of the procedures. RESULTS Surgical treatments provide the best outcomes for cSCC. Mohs micrographic surgery is a cost-effective procedure that affords the highest cure rate, maximal tissue preservation, and superior cosmetic outcomes. Nonsurgical methods may be used as a primary treatment for low-risk squamous cell carcinomas, but the cure rates are lower. CONCLUSION The cure rate remains the most important consideration in choosing the treatment method, but additional factors, such as the patient's general medical condition, psychosocial circumstances, the location of the tumor and cost effectiveness of the therapy should be considered. Mohs micrographic surgery remains the preferred treatment for high-risk tumors and tumors located in cosmetically sensitive areas.

Abstract
Skin cancer is the most common cancer in the USA and is increasing in children and young adults. Adolescents are an important target population for sun-safety interventions with ultraviolet radiation as the strongest risk factor for developing skin cancer. Schools are an ideal setting to intervene with adolescents. A novel Arizona skin cancer prevention in-class education-activity program, Project 'Students are Sun Safe' (SASS), was designed to be delivered by university students for middle school and high school students. Participant students completed the pre- and post-program tests and a satisfaction questionnaire; teachers completed reviews. The evaluation examined the program's influence on participants' sun-safety knowledge, perceptions, and behaviors; satisfaction with the program; and intent to change. After exposure to Project SASS, participants were more likely to perceive a high risk of skin cancer, report negative attitudes toward tanned skin, and answer knowledge-based questions correctly. There were minimal differences in self-reported sun-safety behaviors, though participants did report intent to change. Both participants and teachers were satisfied with the program. Project SASS appears to be an effective sun-safety program for middle school and high school students for knowledge and perceptions, and the results confirm that appropriately tailoring program components to the target population has strong potential to impact adolescent perceived susceptibility, knowledge, and behavioral intent. The strengths and weaknesses of Project SASS have many implications for public health practice, and Project SASS may hold promise to be a model for skin cancer prevention in adolescents.

Abstract
Background: Despite its increased incidence and status as the most prevalent cancer in Canada, there is a paucity of epidemiological data on non-melanoma skin cancer (NMSC). Objective: To assess trends of keratinocyte carcinomas (KC) in Canada over 5 decades. Methods: Articles published from 1960 to 2015 on NMSC in Canada were identified through MEDLINE. Six articles met our search criteria. Results: Overall, KC has increased. However, the rate of increase in the past decade has slowed down and decreased in younger age cohorts. Men had higher incidences of KC. In both sexes, the basal cell carcinoma and squamous cell carcinoma ratio was ≥2.5:1. Keratinocyte carcinomas were most commonly located on the head and neck, and increasing rates are occurring on the trunk. Limitations: The methods of registering skin cancer cases vary among different provinces. Conclusion: Keratinocyte carcinomas incidence is overall increasing; however, there may be evidence that the incidence is leveling off and decreasing in younger age cohorts.

Abstract
The incidence of skin cancer is higher than all other cancers and continues to increase, with an average annual cost over $8 billion in the United States. As a result, identifying molecular pathway alterations that occur with UV exposure to strategize more effective preventive and therapeutic approaches is essential. To that end, we evaluated phosphorylation of proteins within the PI3K/Akt and MAPK pathways by immunohistochemistry in sun-protected skin after acute doses of physiologically relevant solar-simulated ultraviolet light (SSL) in 24 volunteers. Biopsies were performed at baseline, 5 minutes, 1, 5, and 24 hours after SSL irradiation. Within the PI3K/Akt pathway, we found activation of Akt (serine 473) to be significantly increased at 5 hours while mTOR (serine 2448) was strongly activated early and was sustained over 24 hours after SSL. Downstream, we observed a marked and sustained increase in phospho-S6 (serine 235/S236), whereas phospho-4E-BP1 (threonines 37/46) was increased only at 24 hours. Within the MAPK pathway, SSL-induced expression of phospho-p38 (threonine 180/tyrosine 182) peaked at 1 to 5 hours. ERK 1/2 was observed to be immediate and sustained after SSL irradiation. Phosphorylation of histone H3 (serine 10), a core structural protein of the nucleosome, peaked at 5 hours after SSL irradiation. The expression of both p53 and COX-2 was increased at 5 hours and was maximal at 24 hours after SSL irradiation. Apoptosis was significantly increased at 24 hours as expected and indicative of a sunburn-type response to SSL. Understanding the timing of key protein expression changes in response to SSL will aid in development of mechanistic-based approaches for the prevention and control of skin cancers.

Abstract
Non-melanoma skin cancer (NMSC), including basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), is the most common cancer occurring in people with fair skin. Australia has been reported to have the highest incidence of NMSC in the world. Using a systematic search of the literature in EMBASE and Medline, we identified 21 studies that investigated the incidence or prevalence of NMSC in Australia. Studies published between 1948 and 2011 were identified and included in the analysis. There were six studies that were conducted on national level, two at state level and 13 at the regional level. Overall, the incidence of NMSC had steadily increased over calendar-years in Australia. The incidence of NMSC per 100,000 person-years was estimated to be 555 in 1985; 977 in 1990; 1109 in 1995; 1170 in 2002 and 2448 in 2011. The incidence was higher for men than women and higher for BCC than SCC. Incidence varied across the states of Australia, with the highest in Queensland. The prevalence of NMSC was estimated to be 2% in Australia in 2002. The incidence and prevalence of NMSC still need to be accurately established at both national and state levels to determine the costs and burden of the disease on the public health system in Australia.

Abstract
Purpose. We reviewed the literature on sun protection beliefs in Hispanics living in the United States to explore what challenges are faced by area of research. Method. A review of PubMED, PsycINFO, and CINAHL databases was performed. Studies were published in peer-reviewed journals (in all years available) and written in English. The search terms used were [“skin cancer” OR “sun protection”] AND [“Latino” OR “Hispanic”] AND “beliefs.” Eligible papers were included in the final analysis after meeting the following inclusion criteria: (1) the records had to quantitatively examine and report sun protection beliefs in Hispanics, (2) the number of Hispanic participants in the sample had to be clearly specified, and (3) studies reporting differences in sun protection beliefs between Hispanics and other racial and ethnic groups were included in the review. Results. Of the 92 articles identified, 11 met inclusion criteria and addressed sun protection beliefs regarding skin cancer seriousness and susceptibility, and benefits and barriers of sun protection and skin cancer risk behaviors. Characteristics of studies and results were examined. Conclusion. There is insufficient evidence to determine a pattern of sun protection beliefs among Hispanics in the United States. More quality studies are needed which focus on sun protection beliefs in Hispanics.

Abstract
Little data on cutaneous squamous cell carcinoma (SCC) epidemiology within the United States are currently available. Prior studies have focused on populations outside of the United States or been limited to regions within the US. In this study, prospective data were collected via biennial questionnaires from a total of 261,609 participants, which included women in the Nurses' Health Study (NHS, 1976-2008) and Nurses' Health Study II (NHS II, 1989-2009), and men in the Health Professionals Follow-Up Study (HPFS, 1986-2008). History of physician-diagnosed invasive SCC was confirmed by pathology record review. Over the entire follow-up period for each cohort, there were 1,265 invasive SCC cases per 100,000 persons in the NHS cohort, 389 cases per 100,000 persons in NHS II, and 2,154 cases per 100,000 persons in HPFS. An 18-year follow-up of participants in these cohorts revealed increasing invasive SCC incidence rates over time, with rates for men being consistently higher than those for women. In women, a larger proportion of invasive SCC lesions occurred on the lower extremities as compared to men (21 % in NHS vs. 6 % in HPFS, p < 0.0001; 14 % in NHS II vs. 6 % in HPFS, p < 0.0001), while in men, a larger proportion occurred on the head/neck (43 % in NHS vs. 60 % in HPFS, p < 0.0001; 48 % in NHS II vs. 60 % in HPFS, p < 0.0001). In summary, invasive SCC incidence rates among US men have been greater than those for women with distinct sites of common occurrence between men and women.

Abstract
Skin has the highest incidence and variety of tumors of all organs. Its structure is of great complexity, and every component has the potential to originate a skin neoplasm (SN). Because of its exposed nature, skin is vulnerable to carcinogenic stimuli such as UV radiation. Various entities can cause SN. Nonmelanotic skin cancers (NMSC) are the most common of all cancers, with over one million cases diagnosed annually in the US. Basal cell carcinoma (BCC) accounts for approximately 80% of all NMSC, most of the remaining 20% being squamous cell carcinoma (SCC). The skin of the head and neck is the most common site for tumors, accounting for more than 80% of all NMSC. BCC, SCC, and malignant melanomas (MM) represent 85-90% of all SN. Merkel cell tumors (MCC), lymphoepithelioma-like carcinomas of the skin (LELCS), dermato-fibro-sarcomas, leiomyosarkomas, and Kaposi-sarcomas are less frequent in the facial skin region and the external ear. Based on data from the German Federal Cancer Registry (2003/2004), 140,000 people in Germany were affected by SN (100,000 BCC, 22,000 SCC, 22,000 MM). This number increases considerably if malignant precursors, such as actinic keratosis, are included. Each year, the frequency of SN diagnosis rises by 3-7%. Among all known malignant tumors, MM exhibits the highest rate of increase in incidence. In the past, SN was primarily diagnosed in people aged 50 years or older. However, recently, the risk for developing SN has shifted, and younger people are also affected. Early diagnosis is significantly correlated with prognosis. Resection of SN creates defects that must be closed with local or microvascular flaps to avoid functional disturbing scar formation and deflection of the nose, eyelids, or lips. All therapeutic strategies for SN, the current standard for adjuvant and systemic treatment, and the management of the increasing number of patients under permanent blood thinner medication are described with regard to the treatment of SN.

Abstract
There is a paucity of data on basal-cell carcinoma (BCC) in the United States, since most national registries do not collect information on BCC. We evaluated BCC incidence trends and associated risk factors for BCC in 140,171 participants from a U.S. female cohort, the Nurses' Health Study (1986-2006), and a U.S. male cohort, the Health Professionals' Follow-up Study (1988-2006). Age-adjusted BCC incidence rates increased from 519 cases per 100,000 person-years to 1,019 cases per 100,000 person years for women and increased from 606 cases per 100,000 person-years to 1,488 cases per 100,000 person-years for men during the follow-up period. Cox proportional hazards analysis identified the following phenotypic risk factors for BCC in both cohorts: family history of melanoma, blond or red hair colors, higher number of extremity moles, higher susceptibility to sunburn as a child/adolescent, and higher lifetime number of severe/blistering sunburns. The multivariate-adjusted risk ratio for the highest quintile of cumulative midrange ultraviolet B flux exposure versus the lowest quintile was 3.18 (95% confidence interval: 2.70, 3.76) in women and 1.90 (95% confidence interval: 1.57, 2.29) in men. BCC incidence was generally higher in men than in women, and BCC risk was strongly associated with several phenotypic and exposure factors, including midrange ultraviolet B radiation, in our study populations.

Abstract
BACKGROUND AND OBJECTIVE The present study was undertaken to assess the pattern of skin malignancies in Qassim region, Kingdom of Saudi Arabia. METHODS Data of histopathological confirmed cases of skin malignancies were collected from all the referral hospitals of Qassim region during a period from January 2000 to July 2009. RESULTS Out of 94 cases majority (90.4%) were Saudis, and males (74.5%). The most common malignant skin lesion was BCC (58.5%) followed by SCC (18.1%) and MM (11.7%), respectively. Other malignancies seen were DFSP (4.3%), sebaceous carcinoma (2.1%) and skin secondaries from lung, lymphoma and stomach (4.3%). The most common site was face for BCC, trunk for SCC, and limbs for MM. The DFSP did not show any particular pattern. CONCLUSION All major types of skin malignancies were seen with patterns similar to those reported from various other regions of Saudi Arabia and other countries except for Kaposi's sarcoma which was not encountered in our study.

Abstract
BACKGROUND Basal cell carcinoma (BCC) is the most common cancer in Caucasians. Treatment options include electrodesiccation and curettage (EDC), surgical excision, and Mohs micrographic surgery (MMS). EDC is standard for smaller BCCs in low-risk locations with nonaggressive histologic subtypes. Larger BCCs in higher-risk locations and aggressive histologic subtypes are treated using surgical excision or MMS. We found no studies reporting recurrence rates for aggressive BCC subtypes treated using EDC alone. OBJECTIVE To determine recurrence rates of histologically aggressive BCC treated using EDC. METHODS AND MATERIALS This population-based, retrospective case study reviewed 37 primary infiltrative, desmoplastic, morpheaform, or micronodular BCCs in 34 patients treated with EDC. Recurrence was defined as reappearance of BCC within the boundaries of or contiguous to the scar resulting from initial treatment. RESULTS Of 37 primary aggressive BCCs, 10 recurred within 3.3 years. Average primary tumor diameter was 0.69 cm. Average primary tumor diameter was 0.73 cm for those that recurred and 0.67 cm for those that did not recur. Six recurrences were in high-risk areas, three in moderate-risk areas, and one in a low-risk area. CONCLUSION We report a 27% recurrence rate for histologically aggressive BCCs treated using EDC alone with median 6.5 years follow-up.
