Abstract
Mortality from cutaneous malignant melanoma (CMM) increased in the past, but trends have been favorable in more recent years in many high-income countries. However, incidence has been increasing in several countries. We provided an up-to-date overview of mortality trends from CMM. We analyzed death certification data from the WHO in selected countries worldwide from 1980 to the most recent available calendar years. We also reported incidence data derived from Cancer Incidence in Five Continents from 1990 to 2012. Separate analyses were performed for young adults aged 20-44 and middle-aged adults aged 45-64 years. Mortality from CMM in all age groups showed a favorable pattern in the majority of the countries considered. Mortality trends declined by 40 to 50% in Australia over the last decades, confirming the importance of prevention measures. Considering young adults aged 20-44, Australia, New Zealand and Northern Europe reported the highest death rates for both sexes (>0.90/100 000 in men and >0.60/100 000 in women) while Japan, the Philippines, and Latin America the lowest ones (<0.50/100 000 and <0.35/100 000 in men and women, respectively). Incidence trends were stable or upward in most countries, with higher rates among women. Our study highlights a global reduction of CMM mortality over the last three decades. The increasing awareness of risk factors, mainly related to UV exposure, along with early diagnosis and progress in treatment for advanced disease played pivotal roles in reducing CMM mortality, particularly in Australia.

Body Site Distribution of Acquired Melanocytic Naevi and Associated Characteristics in the General Population of Caucasian Adults: A Scoping Review. Dermatol Ther (Heidelb) 2022; 12:2453-2488. [PMID: 36180760 PMCID: PMC9588131 DOI: 10.1007/s13555-022-00806-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Accepted: 08/30/2022] [Indexed: 11/26/2022] Open
Abstract
The number of melanocytic naevi is a major risk factor for melanoma. The divergent pathway hypothesis proposes that the propensity for naevus proliferation and malignant transformation may differ by body site and exposure to ultraviolet (UV) radiation. This scoping review aimed to summarise the evidence on the number and distribution of naevi (≥ 2 mm) on the body overall and by individual anatomical sites in Caucasian adults, and to assess whether studies used the International Agency for Research on Cancer (IARC) protocol to guide naevus counting processes. Systematic searches of Embase and PubMed identified 661 potentially relevant studies, and 12 remained eligible after full-text review. Studies varied widely in their counting protocols, reporting of naevus counts overall and by body sites, and used counting personnel with differing qualifications. Only one study used the IARC protocol. Studies reported that the highest number of naevi was on the trunk in males and on the arms in females. Body sites which receive intermittent exposure to UV radiation had higher density of naevi. Larger naevi (≥ 5 mm) were detected mostly on body sites intermittently exposed to UV radiation, and smaller naevi (< 5 mm) on chronically exposed sites. Studies reported that environmental and behavioural aspects related to UV radiation exposure, as well as genetic factors, all impact body site and size distribution of naevi. This review found that to overcome limitations of the current evidence, future studies should use consistent naevus counting protocols. Skin surface imaging could improve the reliability of findings. An updated IARC protocol is required that integrates these emerging standards and technologies to guide reliable and reproducible naevus counting in the future.

Integrating Patient Data Into Skin Cancer Classification Using Convolutional Neural Networks: Systematic Review. J Med Internet Res 2021; 23:e20708. [PMID: 34255646 PMCID: PMC8285747 DOI: 10.2196/20708] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Revised: 10/29/2020] [Accepted: 04/13/2021] [Indexed: 11/17/2022] Open
Abstract
Background Recent years have been witnessing a substantial improvement in the accuracy of skin cancer classification using convolutional neural networks (CNNs). CNNs perform on par with or better than dermatologists with respect to the classification tasks of single images. However, in clinical practice, dermatologists also use other patient data beyond the visual aspects present in a digitized image, further increasing their diagnostic accuracy. Several pilot studies have recently investigated the effects of integrating different subtypes of patient data into CNN-based skin cancer classifiers. Objective This systematic review focuses on the current research investigating the impact of merging information from image features and patient data on the performance of CNN-based skin cancer image classification. This study aims to explore the potential in this field of research by evaluating the types of patient data used, the ways in which the nonimage data are encoded and merged with the image features, and the impact of the integration on the classifier performance. Methods Google Scholar, PubMed, MEDLINE, and ScienceDirect were screened for peer-reviewed studies published in English that dealt with the integration of patient data within a CNN-based skin cancer classification. The search terms skin cancer classification, convolutional neural network(s), deep learning, lesions, melanoma, metadata, clinical information, and patient data were combined. Results A total of 11 publications fulfilled the inclusion criteria. All of them reported an overall improvement in different skin lesion classification tasks with patient data integration. The most commonly used patient data were age, sex, and lesion location. The patient data were mostly one-hot encoded. There were differences in the complexity that the encoded patient data were processed with regarding deep learning methods before and after fusing them with the image features for a combined classifier. Conclusions This study indicates the potential benefits of integrating patient data into CNN-based diagnostic algorithms. However, how exactly the individual patient data enhance classification performance, especially in the case of multiclass classification problems, is still unclear. Moreover, a substantial fraction of patient data used by dermatologists remains to be analyzed in the context of CNN-based skin cancer classification. Further exploratory analyses in this promising field may optimize patient data integration into CNN-based skin cancer diagnostics for patients’ benefits.

Abstract
BACKGROUND Melanoma is one of the highest metastatic cancers and its incidence is rapidly increasing. A great effort has been devoted to determine gene mutations and expression profiles in melanoma cells, but less attention has been given to the possible influence of melanin synthesis in melanocytes on melanomagenesis. SLC7A11 encodes the cystine/glutamate antiporter xCT and its expression increases the antioxidant capacity of cells by providing cysteine that may be used for glutathione (GSH) synthesis. Melanocytes, however, can also use cysteine for pheomelanin synthesis and pigmentation. Therefore, pheomelanin synthesis may lead to chronic oxidative stress. Possible consequences of this for melanomagenesis have never been explored. METHODS We quantified the expression of SLC7A11 and other genes that are involved in the synthesis of pheomelanin but do not regulate the transport of cysteine from the extracellular medium to the cytosol (CTNS, MC1R, ASIP and SLC45A2) in non-tumorous skin of 45 patients of cutaneous melanoma and 50 healthy individuals. We controlled for the effects of Fitzpatrick skin type, age, gender, body mass, frequency of sun exposure and sunburns and number of melanocytic nevi, as well as for the intrinsic antioxidant capacity as given by the expression of the gene NFE2L2. RESULTS The expression of SLC7A11, but not of the other genes, was significantly higher in melanoma patients than in healthy individuals. This was independent of phenotypic factors and antioxidant capacity, thus supporting an effect of pheomelanin-induced oxidative stress on melanomagenesis. CONCLUSION Our findings indicate that SLC7A11 downregulation in normal epidermal melanocytes may represent a preventive treatment against melanoma.

Abstract
Aims and background Sunburn during childhood is associated with an increased risk for developing melanoma in an adult age. The aim of the present study was to define the validity of our educational program in order to teach the positive effects and risks of sun exposure during childhood. Patients and methods We conducted a population-based, case-control study in primary schools of three towns in Northern Italy (Brescia, Bergamo and Trento) between 2001 and 2002. The study was carried out on 1945 pupils (aged 8-9 years) and included 1309 case children who received an educational program before the summer to increase awareness towards sun exposure and 636 control children who did not. Parents of case and control children were interviewed using a questionnaire about their children's skin characteristics, sun protective behavior and sunburns. The questionnaire was completed twice, before and after the summer, to verify the changes of sun exposure habits. Results A significant decrease in sunburns was demonstrated in the group of subjects who received the educational program, indicating the validity of our operative procedure (from 14.6% to 10%, P = 4 × 10−4). Conclusions Our educational melanoma program may be important to disseminate in a wider range of children a correct education on sun exposure during childhood.

Abstract
BACKGROUND/OBJECTIVES High a naevus counts and atypical naevi are risk factors for cutaneous melanoma. However, many individuals with a high-risk naevus phenotype do not develop melanoma. In this study, we describe the clinical and dermoscopic attributes of naevi associated with melanoma in a high-risk naevus phenotype population. METHODS This single-centre, hospital-based case-control study included 54 prospectively enrolled adult patients ≥18 years old with a high-risk naevus phenotype (18 cases with a history of melanoma and 36 age- and gender-matched controls without a history of melanoma). We analysed clinical and dermoscopic images of the 20 largest naevi for each participant. RESULTS Cases had a higher mean age than controls (48.2 vs. 39.1 years, P = 0.007) but there was no difference in the male-to-female ratio between groups. Nearly, all participants (97%) were Fitzpatrick skin type II or III. Naevi in cases were more likely to be truncal, (72.6% vs. 53.6%, P = 0.01), particularly anterior truncal, (29.2% vs. 14.4%, P < 0.001) and larger than 8 mm (17.4% vs. 7.8%%, P = 0.01) compared to controls. CASH score of naevi did not differ between groups. Naevi in cases were more likely to have a multicomponent dermoscopic pattern than in controls (18.4% vs. 12.6%, P = 0.02). CONCLUSION Larger naevi, truncal naevi, and naevi, with a multicomponent dermoscopic pattern may be risk factors for melanoma among individuals with a high-risk naevus phenotype. Further studies are needed to validate these findings.

Abstract
BACKGROUND Many melanoma observational studies have been carried out across different countries and geographic areas using heterogeneous assessments of epidemiologic risk factors and clinical variables. AIM To develop a consensus questionnaire to standardize epidemiologic and clinical data collection for melanoma risk assessment. METHODS We used a stepwise strategy that included: compilation of variables from case-control datasets collected at various centres of the MelaNostrum Consortium; integration of variables from published case-control studies; consensus discussion of the collected items by MelaNostrum members; revision by independent experts; addition of online tools and image-based charts; questionnaire testing across centres and generation of a final draft. RESULTS We developed a core consensus questionnaire (MelanoQ) that includes four separate sections: A. general and demographic data; B. phenotypic and ultraviolet radiation exposure risk factors and lifestyle habits; C. clinical examination, medical and family history; and D. diagnostic data on melanoma (cases only). Accompanying online tools, informative tables, and image-based charts aid standardization. Different subsections of the questionnaire are designed for self-administration, patient interviews performed by a physician or study nurse, and data collection from medical records. CONCLUSIONS The MelanoQ questionnaire is a useful tool for the collection and standardization of epidemiologic and clinical data across different studies, centres, cultures and languages. This will expedite ongoing efforts to compile high-quality data for pooled analyses or meta-analyses and offer a solid base for the design of clinical, epidemiologic and translational studies on melanoma.

Abstract
Although melanoma risk factors are commonly known to healthcare professionals, the extent to which the at-risk public is either aware of these factors or perceives their risk accordingly has rarely been studied. We sought to investigate whether the presence of known melanoma risk factors, such as high total nevus and atypical nevus counts, was associated with increased prevention attitudes and behaviors, such as skin self-examinations and physician skin examinations. This was a retrospective study of 566 individuals recently diagnosed with melanoma in two large academic centers. Most prevention attitudes and behaviors did not vary on the basis of total nevi or atypical nevi counts. However, younger patients (<60 years) with many total nevi (>50) were more likely than those with fewer nevi (<20) to believe that they were at-risk for melanoma (42 vs. 23%; P<0.05), and more likely to state that they had been instructed on the signs of melanoma (36 vs. 21%; P<0.05). Patient and health provider recognition of the impact of nevus count on melanoma risk presents a unique and mostly untapped opportunity for earlier detection.

J Skin Cancer 2016; 2016:2105250.

Abstract
United States Hispanics have seven times lower melanoma incidence rates than non-Hispanic whites (NHW). It is unclear whether this difference can be explained solely by phenotypic risk factors, like darker skin, or whether modifiable risk factors, like sun exposure, also play a role. The purpose of this paper is to summarize what is currently known about melanoma risk factors among Hispanics and NHWs, and whether or not those differences could explain the difference in melanoma incidence. Through literature review, relative risks and prevalence of melanoma risk factors in Hispanics and NHWs were identified and used to calculate the expected rate in Hispanics and rate ratio compared to NHWs. We found that melanoma risk factors either have similar frequency in Hispanics and NHWs (e.g., many large nevi) or are less frequent in Hispanics but do not explain a high proportion of disease variation (e.g., red hair). Considering current knowledge of risk factor prevalence, we found that melanoma incidence rates in the two groups should actually be similar. Sun exposure behavior among Hispanics may contribute to the explanation for the 7-fold difference in melanoma rates. Currently, limited data exist on sun exposure behavior among Hispanics, but possibilities for improving primary prevention by further studying these practices are substantial.

Abstract
BACKGROUND Light skin pigmentation is a known risk factor for skin cancer. OBJECTIVE Skin color parameters and Fitzpatrick phototypes were evaluated in terms of their usefulness in predicting the risk of skin cancer. METHODS A case-control study involved 133 individuals with skin cancer (100 with basal cell carcinoma, 21 with squamous cell carcinoma, 12 with melanoma) and 156 healthy individuals. All of them had skin phototype determined and spectrophotometric skin color measurements were done on the inner surfaces of their arms and on the buttock. Using those data, prediction models were built and subjected to 17-fold stratified cross-validation. RESULTS A model, based on skin phototypes, was characterized by area under the receiver operating characteristic curve = 0.576 and exhibited a lower predictive power than the models, which were mostly based on spectrophotometric variables describing pigmentation levels. The best predictors of skin cancer were R coordinate of RGB color space (area under the receiver operating characteristic curve 0.687) and melanin index (area under the receiver operating characteristic curve 0.683) for skin on the buttock. LIMITATIONS A small number of patients were studied. Models were not externally validated. CONCLUSIONS Skin color parameters are more accurate predictors of skin cancer occurrence than skin phototypes. Spectrophotometry is a quick, easy, and affordable method offering relatively good predictive power.

Abstract
BACKGROUND Neonatal blue light phototherapy (NBLP) is an established method of managing neonatal hyperbilirubinemia. Approximately 5% of newborns are exposed to NBLP. Evidence of whether NBLP predisposes to the development of melanocytic nevi later in life has been conflicting. OBJECTIVES The goal of the current study was to conduct a systematic review and meta-analysis to quantitatively assess the effect of NBLP on melanocytic nevus count. METHODS We searched for observational studies in Medline, EMBASE, and the Cochrane Central Register from their inception to April 15, 2015. Meta-analysis of Observational Studies in Epidemiology guidelines were followed. DerSimonian and Laird random-effects models were used to calculate the weighted mean difference (WMD). Publication bias was assessed using a funnel plot and the Egger's test. RESULTS Five studies with a total of 2,921 subjects were included, of whom 642 underwent NBLP. With random-effects modeling, those who had previous NBLP did not have a significantly higher mean number of melanocytic nevi (WMD = 0.32 [95% confidence interval -0.67, 1.31], p = 0.53). Visual inspection of the funnel plot suggested potential publication bias, although the Egger's test (p = 0.09) indicated no small-study effect. CONCLUSION There was no evidence that prior NBLP exposure significantly increased the number of melanocytic nevi. Available evidence has not revealed any cause for major concern for NBLP. Other risk factors such as exposure to sunlight, childhood history of sunburn, and fair skin complexion might play a greater role in the development of melanocytic nevi in childhood.

Abstract
Environmental and genetic risk factors are involved in the development of melanoma. The role of the melanocortin 1 receptor (MC1R) gene has been investigated and differences according to geographic areas have been described. To evaluate the role of some clinical and genetic risk factors in melanoma development, we performed a case-control study involving 101 melanoma patients and 103 controls coming from South-Eastern Italy (Puglia), after achieving informed consent. We confirmed the role of known clinical risk factors for melanoma. Furthermore, 42 MC1R polymorphisms were observed. Three of these variants (L26V, H232L, D294Y) were not previously reported in the literature. Their predicted impact on receptor function was evaluated using bioinformatic tools. We report an overall frequency of MC1R variants in our population higher than in Northern or Central Italy. The most common polymorphism found was V60L, that has been recently reported to spread among South Mediterranean population. This variant influenced phenotypic characteristics of our population while it did not impinge on melanoma risk. An increased risk of melanoma was associated with two or more MC1R variants, when at least one was RHC, compared to people carrying the MC1R consensus sequence or a single MC1R polymorphism. Interestingly, we observed an increased risk of melanoma in subjects with darker skin and lower nevus count, usually considered at low risk, when carrying MC1R polymorphisms.

Abstract
Previous studies on the association of solar lentigines with ultraviolet radiation (UVR) exposure have been based on retrospective questionnaires about UVR exposure. We aimed to investigate the association between solar lentigines and UVR exposure in healthy individuals using objective measurements, and to investigate the association between solar lentigines and cutaneous malignant melanoma (CMM). Forty-eight patients with CMM and 48 controls that matched the patients individually by age, sex, constitutive skin type and occupation participated. Solar lentigines on the shoulders and upper back were counted and graded into 3 categories using black light photographs to show sun damage. Current UVR exposure in healthy controls was assessed by personal electronic UVR dosimeters that measured time-related UVR and by corresponding exposure diaries during a summer season. Sunburn history was assessed by interviews. Among controls, the number of solar lentigines was positively associated with daily hours spent outdoors between noon and 3 pm on holidays (P = 0.027), days at the beach (P = 0.048) and reported number of life sunburns (P < 0.001). Compared with matched controls CMM patients had a higher number of solar lentigines (P = 0.044). There was a positive association between CMM and higher solar lentigines grade; Category III versus Category I (P = 0.002) and Category II versus Category I (P = 0.014). Our findings indicate that solar lentigines in healthy individuals are associated with number of life sunburns, as well as time spent outdoors around noon on holidays and beach trips during a summer season, most likely reflecting past UVR exposure, and that solar lentigines are a risk factor for CMM.

Abstract
BACKGROUND The incidence of melanoma and nonmelanoma skin cancer continues to increase. To detect lesions at an earlier phase in their progression, skin cancer screening programs have been advocated by some. However, the effectiveness of skin cancer screening and the ideal population that these screenings should target have yet to be firmly established. This study details the relationship of a group of well-known risk factors with presumptive diagnoses in a large series of individuals self-referred for free skin cancer screening. METHODS Data obtained during 2007 to 2010 from a descriptive cross-sectional study skin cancer screening program are presented. Participant history was recorded using standardized medical history forms prior to skin examination. Screeners conducted a skin examination varying from whole-body to limited areas (per participant preference) and recorded diagnoses. Diagnoses were assigned to the nonmelanoma cancer (NMC) or suspicious pigmented lesion group for analysis. RESULTS A presumptive diagnosis of NMC was associated with male sex, age ≥ 50 years, personal history of skin cancer, lower skin phototype, increased sunscreen use, and increased chronic sun exposure (all P values ≤ .0001). After controlling for skin phototype, increased sunscreen use was not associated with a presumptive diagnosis of NMC (P = .96). Presumptive diagnosis of a suspicious pigmented lesion was associated with a reported history of "changing mole" (P < .0001) and negatively associated with age ≥ 50 years (P < .0001) and a personal history of skin cancer (P = .0119). CONCLUSIONS Several known risk factors for nonmelanoma skin cancer correlated with a presumptive diagnosis of NMC. The yield of presumptive atypical pigmented lesions was increased in participants aged < 50 years, supporting the notion that this population may benefit from screening.

Abstract
BACKGROUND UV radiation and the presence of melanocytic nevi are the main risk factors of sporadic melanoma (MM). Protection of skin by an oral photoprotective agent would have substantial benefits. OBJECTIVE We investigated the possible role of an oral Polypodium leucotomos (PL) extract to improve systemic photoprotection in patients at risk of skin cancer analyzing the ability to decrease UV-induced erythema. We also studied the interaction among MC1R polymorphisms and CDKN2A status with the minimal erythematous dose (MED) and their influence in the response after oral PL. METHODS A total of 61 patients (25 with familial and/or multiple MM, 20 with sporadic MM and 16 with atypical mole syndrome without history of MM) were exposed to varying doses of artificial UVB radiation without and after oral administration of a total dose of 1080 mg of PL. RESULTS Oral PL treatment significantly increased the MED mean in all group patients (0.123 to 0.161 J/cm(2) , p<0.05). Although not significant, we noticed a stronger effect of PL on the MED of patients with familial MM compared to those with MM (U=273, p=0.06). Among the patients with familial MM, those exhibiting a mutated CDKN2A and/or polymorphisms in MC1R had the bigger differences in response to treatment with PL. LIMITATIONS Reduced number of patients. No control population. CONCLUSIONS Administration of PL leads to a significant reduction of sensitivity to UVR (p<0.05) in all patients. Dark-eye patients and patients with higher UVR sensibility (lower basal MED) would be the most benefited from oral PL treatment.

Abstract
Sun exposure is causal for melanoma but is subject to bias of recall so that it is difficult to dissect the role of particular patterns of sun exposure. In this hospital-based case-control study (n = 1991), we aimed to analyze pigmentation traits and signs of actinic damage at different anatomic locations as markers of melanoma risk in central European patients. Although all signs of actinic damage (freckling, wrinkling and solar lentigos) were significantly associated with melanoma risk in multivariate logistic regression models adjusting for age and sex, the strongest associations were observed for the dorsal parts of the body: adjusted odds ratios [OR] were 4.22 for wrinkling on the neck, 3.43 for solar lentigos and 3.37 for freckling on the back (all P < 0.001), respectively. These associations were independent of age, sex and pigmentation traits. Our results indicate that signs of actinic damage are predictors of melanoma risk, particularly on the back.

Abstract
BACKGROUND Malignant melanomas clinically and/or histologically associated with melanocytic nevi have been reported worldwide. Approximately 20% of malignant melanomas in Caucasians, most of which are found on the trunk and proximal extremities, develop in association with pre-existing melanocytic nevi. In Japan, however, over half of all melanomas are acral lentiginous melanomas (ALMs) on the hands and feet; melanomas on sun-exposed areas are seen less frequently in Japanese people than in Caucasians. As ALMs are not usually accompanied by melanocytic nevi and there have been no reviews of the literature or statistical data regarding Japanese cases of melanomas with melanocytic nevi, dermatologists in Japan have few opportunities to see melanomas associated with pre-existing melanocytic nevi. METHODS Here we report a case of a superficial spreading melanoma that was formed on a melanocytic nevus on the trunk, and we review for the first time the case reports from the Japanese literature. RESULTS AND CONCLUSIONS With regard to the reported cases, melanomas associated with melanocytic nevi were mainly superficial spreading melanomas and nodular melanomas on the trunk or extremities; ALMs were rarely associated with nevi, indicating a trend similar to that observed in Caucasians. These findings suggest that the low frequency of associations between melanomas and melanocytic nevi in Japan reflects racial differences in the frequencies of each type of melanoma.

Abstract
Epidemiologic research has demonstrated convincingly that certain pigmentary characteristics are associated with increased relative risks of melanoma; however there has been no comprehensive review to rank these characteristics in order of their importance on a population level. We conducted a systematic review of the literature and meta-analysis to quantify the contribution of pigmentary characteristics to melanoma, estimated by the population-attributable fraction (PAF). Eligible studies were those that permitted quantitative assessment of the association between histologically confirmed melanoma and hair colour, eye colour, skin phototype and presence of freckling; we identified 66 such studies using citation databases, followed by manual review of retrieved references. We calculated summary relative risks using weighted averages of the log RR, taking into account random effects, and used these to estimate the PAF. The pooled RRs for pigmentary characteristics were: 2.64 for red/red-blond, 2.0 for blond and 1.46 for light brown hair colour (vs. dark); 1.57 for blue/blue-grey and 1.51 for green/grey/hazel eye colour (vs. dark); 2.27, 1.99 and 1.35 for skin phototypes I, II and III respectively (vs. IV); and 1.99 for presence of freckling. The highest PAFs were observed for skin phototypes 1/II (0.27), presence of freckling (0.23), and blond hair colour (0.23). For eye colour, the PAF for blue/blue-grey eye colour was higher than for green/grey/hazel eye colour (0.18 vs. 0.13). The PAF of melanoma associated with red hair colour was 0.10. These estimates of melanoma burden attributable to pigmentary characteristics provide a basis for designing prevention strategies for melanoma.

Abstract
Malignant melanoma is one of the most aggressive malignancies in human and is responsible for almost 60% of lethal skin tumors. Its incidence has been increasing in white population in the past two decades. There is a complex interaction of environmental (exogenous) and endogenous, including genetic, risk factors in developing malignant melanoma. 8–12% of familial melanomas occur in a familial setting related to mutation of the CDKN2A gene that encodes p16. The aim of this is to briefly review the microanatomy and physiology of the melanocytes, epidemiology, risk factors, clinical presentation, historical classification and histopathology and, more in details, the most recent discoveries in biology and genetics of malignant melanoma. At the end, the final version of 2009 AJCC malignant melanoma staging and classification is presented.

Abstract
Epidemiologic research has shown convincingly that certain phenotypic attributes are associated with increased relative risks of melanoma. Although such findings have intrinsic utility, there have been few attempts to translate such knowledge into estimates of disease burden suitable for framing public health policy. We aimed to estimate the population attributable fraction (PAF) for melanoma associated with melanocytic nevi using relative risk estimates derived from a systematic review and meta-analysis. We identified eligible studies using citation databases, followed by manual review of retrieved references. Of 49 studies identified, 25 and 23, respectively, were included in meta-analyses of atypical and common nevi. For people with > or =1 atypical nevi, the summary relative risk was 3.63 (95% confidence interval, 2.85-4.62), with a PAF of 0.25. The relative risk increased by 1.017 (95% confidence interval, 1.014-1.020) for each common nevus; however, significant heterogeneity in risk estimates was observed. We estimated that 42% of melanomas were attributable to having > or =25 common nevi (PAF 25-49 nevi = 0.15; PAF > or =50 nevi = 0.27), whereas PAFs for low nevus counts were modest (PAF 0-10 nevi = 0.04; PAF 11-24 nevi = 0.07). We modeled PAF under scenarios of varying nevus prevalence; the highest melanoma burden was always among those with high nevus counts (PAF range of 0.31-0.62 for > or =25 common nevi). Patients with > or =25 common nevi and/or > or =1 atypical nevi are a high-risk group, which might be targeted for identification, screening, and education. This work is the necessary first step in designing targeted preventive strategies for melanoma, which must now be overlaid with information about cost and utility.

Abstract
BACKGROUND There is limited but interesting evidence suggesting that endometriosis may be associated with specific pigmentary traits and sun habits. In this case-control study, we aimed to further clarify this point. MATERIALS AND METHODS Consecutive patients with a first laparoscopic diagnosis of endometriosis according to Holt and Weiss criteria were selected as cases. Controls were women who underwent laparoscopy during the same study period, but who were found to be free of the disease. Selected women were interviewed and examined by two trained physicians. An unconditional logistic regression model that included age and baseline variables significantly differing between the two groups was used to estimate the adjusted odds ratios (OR). RESULTS There were 98 women with endometriosis and 94 controls selected. Overall, women with the disease had a more photo-sensitive phenotype and were exposed less to sun or ultraviolet radiation. A statistically significant difference was documented for eye color, skin reaction to first sun exposure, freckles score and the use of tanning creams. The adjusted OR (95% CI) for the disease was 1.95 (1.02-3.72) for women with green/blue eyes, 2.19 (1.12-4.28) for those who frequently/always had skin burn reaction to first sun exposure, 5.67 (1.98-16.24) for those with a higher number of freckles and 0.35 (0.15-0.85) for the use of tanning creams. CONCLUSIONS Women with endometriosis have a specific photo-sensitive phenotype and protect themselves more from the sun. This latter habit may be consequent to the former. We speculate that there is a shared genetic background between pigmentation and endometriosis.

Abstract
Pediatric melanoma is rare but increasing in incidence. Because early diagnosis and treatment improves prognosis, clinicians need to include it as a possible diagnosis when evaluating a pigmented lesion in a pediatric patient. Some risk factors for melanoma include xeroderma pigmentosum, giant congenital melanocytic nevi, dysplastic nevus syndrome, atypical nevi, many acquired melanocytic nevi, family history of melanoma, and immunosuppression. Definitive treatment is with surgical excision. Adjuvant therapies such as chemotherapy, immunotherapy, and radiation therapy can be used in advanced cases.

Abstract
BACKGROUND Cutaneous melanoma accounts for 75% of skin cancer deaths. Standard treatment is surgical excision with a safety margin some distance from the borders of the primary tumour. The purpose of the safety margin is to remove both the complete primary tumour and any melanoma cells that might have spread into the surrounding skin.Excision margins are important because there could be trade-off between a better cosmetic result but poorer long-term survival if margins become too narrow. The optimal width of excision margins remains unclear. This uncertainty warrants systematic review. OBJECTIVES To assess the effects of different excision margins for primary cutaneous melanoma. SEARCH STRATEGY In August 2009 we searched for relevant randomised trials in the Cochrane Skin Group Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (Issue 3, 2009), MEDLINE, EMBASE, LILACS, and other databases including Ongoing Trials Registers. SELECTION CRITERIA We considered all randomised controlled trials (RCTs) of surgical excision of melanoma comparing different width excision margins. DATA COLLECTION AND ANALYSIS We assessed trial quality, and extracted and analysed data on survival and recurrence. We collected adverse effects information from included trials. MAIN RESULTS We identified five trials. There were 1633 participants in the narrow excision margin group and 1664 in the wide excision margin group. Narrow margin definition ranged from 1 to 2 cm; wide margins ranged from 3 to 5 cm. Median follow-up ranged from 5 to 16 years. AUTHORS' CONCLUSIONS This systematic review summarises the evidence regarding width of excision margins for primary cutaneous melanoma. None of the five published trials, nor our meta-analysis, showed a statistically significant difference in overall survival between narrow or wide excision.The summary estimate for overall survival favoured wide excision by a small degree [Hazard Ratio 1.04; 95% confidence interval 0.95 to 1.15; P = 0.40], but the result was not significantly different. This result is compatible with both a 5% relative reduction in overall mortality favouring narrower excision and a 15% relative reduction in overall mortality favouring wider excision. Therefore, a small (but potentially important) difference in overall survival between wide and narrow excision margins cannot be confidently ruled out.The summary estimate for recurrence free survival favoured wide excision [Hazard Ratio 1.13; P = 0.06; 95% confidence interval 0.99 to 1.28] but again the result did not reach statistical significance (P < 0.05 level).Current randomised trial evidence is insufficient to address optimal excision margins for primary cutaneous melanoma.

Abstract
Nevi are a main risk factor for malignant melanoma, and most nevi develop in childhood. This study examined the relationship between vacations and nevi in 681 White children born in 1998 who were lifetime residents of Colorado. Vacation histories were assessed through telephone interviews of parents, whereas nevus and phenotypic characteristics were assessed through skin exams at age 7. Multiple linear and logistic regression were used to assess the influence of vacations on counts of nevi <2 mm in size and the presence of any nevi > or = 2 mm after controlling for other variables. Each waterside vacation > or = 1 year before the exam at age 7 was found to be associated with a 5% increase in nevi <2 mm. Waterside vacations <1 year before the skin exam were not related to nevus count (<2 mm); regardless of timeframe, waterside vacations were not related to the presence of nevi > or = 2 mm. UV dose received on waterside vacations, number of days spent on waterside vacations, and nonwaterside vacations were not significantly related to nevi <2 or > or = 2 mm. These results suggest that there is a lag of at least 1 year in the development of new nevi after vacation sun exposure. It appears that a threshold dose of UV exposure is received quickly on each waterside vacation. Parents of young children should exercise caution in selection of vacation locations to reduce melanoma risk.

Abstract
PURPOSE To describe the risk of cutaneous melanoma in the Agricultural Health Study (AHS), a cohort of pesticide applicators and their spouses, according to baseline characteristics related to obesity along with sun exposure and sun sensitivity. METHODS The AHS cohort was enrolled in Iowa and North Carolina during 1993-1997 and followed up through 2003 for cancer incidence. We identified 315 cases of cutaneous melanoma, which reduced to 168 incident cases among subjects reporting height, weight, sun sensitivity, and sun exposure information (on the spouse questionnaire or take-home applicator questionnaire; N = 44,086). Unconditional multiple logistic regression models were used to obtain adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs). RESULTS The results were consistent with those of prior studies of melanoma that indicate an association with measures of sun sensitivity. The highest category of body surface area (BSA; OR = 2.6; 95% CI, 1.5-4.4) and body mass index (BMI; OR = 2.5; 95% CI, 1.5-4.3) at age 20 were significantly associated with melanoma. There was some evidence for an association with BSA, but not BMI, at enrollment. CONCLUSIONS Obesity was associated with an increased risk of melanoma, indicating strategies to control obesity may result in risk reduction for melanoma.

Abstract
A history of sunburns in early life nearly doubles the risk of developing malignant melanoma in adulthood. From 2001 to 2004, we conducted a cluster-randomized trial of an educational intervention to reduce sunburn rates (primary outcome) and improve sun-protection behavior (secondary outcome) in schoolchildren. A total of 122 Italian primary schools (grades 2 and 3) were randomized to receive, or not, an intervention consisting of an educational curriculum at school, conducted by trained teachers, which included the projection of a short video and the distribution of booklets to children and their parents. Behavior while in the sun was assessed at baseline and 14-16 months after baseline. In a subgroup (44% of the total sample), melanocytic nevi were also counted. Of the 11,230 children enrolled, 8,611 completed the study. A total of 1,547 children (14%) reported a history of sunburns at baseline. At follow-up, no difference in sunburn episodes was documented between the study groups (odds ratio 0.97, 95% confidence interval 0.84-1.13) and similar sun-protection habits were reported. No significant impact of the proposed educational program was documented at 1-year follow-up. Innovative strategies need to be developed to increase the effectiveness of future educational interventions in this area.

Abstract
BRAFV600E is the most represented somatic point mutation in cutaneous melanoma, thus providing a unique molecular marker for this disease. The development of efficient methods for its detection in free circulating DNA of patients may lead to the improvement of diagnostic and prognostic tools. With this aim, we evaluated whether BRAFV600E represents a detectable marker in the plasma/serum from melanoma patients in a pilot study. Circulating cell-free DNA was extracted from the serum or plasma of 15 healthy donors and 41 melanoma patients at different clinical stages and obtained either presurgery or after surgery during follow-up. Quantitative analysis showed higher levels of circulating free DNA in patients compared to controls, with the highest levels detected in samples obtained presurgery and at stage IV. Four different PCR methods were compared for their capacity to amplify a few copies of BRAFV600E in wild-type DNA. BRAFV600E was detectable in circulating DNA of 12 patients and in none of the controls; only 1 PCR method reproducibly amplified BRAFV600E. Positive samples were obtained from 8/13 patients at stage IV and from 4/24 patients at stage III, but not in 4 patients at stage I-II; half of the positives were obtained presurgery and half at follow-up. Correspondence between circulating DNA and related tumors were examined for 20 patients, and a correlation was found for stage IV patients. In conclusion, this method can be utilized for monitoring the disease in stage IV melanoma patients but it appears unsatisfactory for the early detection of melanoma.

Abstract
BACKGROUND An immune-mediated defect in recognition and elimination of endometrial fragments refluxed in the peritoneal cavity has been hypothesized to play a crucial role in endometriosis development. Since vitamin D is an effective modulator of the immune system, we have hypothesized that the vitamin D status may have a role in the pathogenesis of endometriosis. METHODS Women of reproductive age selected for surgery for gynecological indications were enrolled in this prospective cohort study. Serum levels of 25-hydroxyvitamin-D(3), 1,25-dihydroxyvitamin-D(3) and Ca(2+) were assessed. RESULTS Eighty-seven women with endometriosis and 53 controls were recruited. Mean (+/- SD) levels of 25-hydroxyvitamin-D(3) in women with and without endometriosis were 24.9 +/- 14.8 ng/ml and 20.4 +/- 11.8, respectively (P = 0.05). The Odds Ratio (95% Confidence Interval) for endometriosis in patients with levels exceeding the 75th percentile of the serum distribution of the molecule (28.2 ng/ml) was 4.8 (1.7-13.5). A positive gradient according to the severity of the disease was also documented. A trend towards higher levels of 1,25-dihydroxyvitamin-D(3) and Ca(2+) was observed in women with endometriosis, but differences did not reach statistical significance. As expected, serum concentrations of 25-hydroxyvitamin-D(3) and 1,25-dihydroxyvitamin-D(3,) but not Ca(2+), are influenced by the season (P < 0.001, P = 0.004, P = 0.57, respectively), while levels of the three molecules did not vary according to the phase of the menstrual cycle. CONCLUSIONS Endometriosis is associated with higher serum levels of vitamin D.

Abstract
Malignant melanoma is an aggressive, therapy-resistant malignancy of melanocytes. The incidence of melanoma has been steadily increasing worldwide, resulting in an increasing public health problem. Exposure to solar UV radiation, fair skin, dysplastic nevi syndrome, and a family history of melanoma are major risk factors for melanoma development. The interactions between genetic and environmental risk factors that promote melanomagenesis are currently the subject of ongoing research. Avoidance of UV radiation and surveillance of high-risk patients have the potential to reduce the population burden of melanoma. Biopsies of the primary tumor and sampling of draining lymph nodes are required for optimal diagnosis and staging. Several clinically relevant pathologic subtypes have been identified and need to be recognized. Therapy for early disease is predominantly surgical, with a minor benefit noted with the use of adjuvant therapy. Management of systemic melanoma is a challenge because of a paucity of active treatment modalities. In the first part of this 2-part review, we discuss epidemiology, risk factors, screening, prevention, and diagnosis of malignant melanoma. Part 2 (which will appear in the April 2007 issue) will review melanoma staging, prognosis, and treatment.

Abstract
The aim of the study was to evaluate malignant melanoma incident trends in central Italy by means of an age-period-cohort approach. A total of 1977 malignant melanoma (15-84 years) incidents in the area of the Tuscany Cancer Registry between 1987 and 2001 were analysed. Poisson regression has been used to estimate age, cohort and period effect. A nonlinear regression model was used to estimate the expected number of new cases in the period 2002-2006. Incidence rates increased in all age, period and cohort groups. The model that best fitted the data included age and 'drift'. The linear effect ('drift') showed, in each age group, an increase of the risk of malignant melanoma diagnosis of about 36.6% every 5 years of period or cohort. For the period 2002-2006, 1112 new cases were predicted with a standardized rate (age 15-84 years) of 19.2x100.000. In the Tuscany Cancer Registry area, no clues for malignant melanoma incidence rates levelling off were documented. Growing rates and number of malignant melanoma are expected in the near future.

Abstract
BACKGROUND Since the year 2000 a melanoma/skin cancer screening campaign has been organized annually in Greece in the context of the Euromelanoma Screening Day Campaign. OBJECTIVES We aimed to analyse the characteristics of the screened population, to recognize relevant risk factors and to identify the cases of histologically confirmed malignant melanoma (MM) in individuals with suspicious skin lesions. METHODS An analysis of the completed screening forms from the years 2000-2004 was performed with respect to relevant demographic, epidemiological and clinical data. RESULTS A total of 9723 individuals were screened, most of whom where below the age of 50 years (71%), female (59%), and of skin phototype II and III (76%). Sunburn during childhood was reported in 47% of participants, while 5% of the screened population had a personal or family history of melanoma. On clinical examination, 14.4% had actinic keratoses, 31.2% had dysplastic nevi, while 6.4% carried a presumptive diagnosis of non-melanoma skin cancer. In the 2003-2004 screening campaign, 19 out of the 171 clinically suspicious lesions were histologically proven to be MM, the majority of which (58%) were 'thin' melanomas (Breslow's thickness of<or=1 mm) of the superficial spreading type. CONCLUSIONS Our study suggested that, a melanoma/skin cancer screening programme in a Mediterranean country, supported by an intense publicity campaign, attracted many individuals at risk for skin cancer and detected mostly thin melanomas of the superficial spreading type.

Abstract
BACKGROUND Multiple solar lentigos commonly seen on the upper back and shoulders of adults are classically considered as a sign of photodamage, although epidemiological studies are scarce. AIM To assess whether these lesions are clinical markers of past severe sunburn. METHODS A case-control study in two outpatient dermatology clinics in French university hospitals. Past episodes of moderate and severe sunburn were compared between 145 adult patients with multiple solar lentigos on the upper back and 145 matched controls. RESULTS In multivariate analysis adjusted for potential confounders, recalled episodes of sunburn during childhood, adolescence and adulthood were independently associated with the presence of multiple solar lentigos (adjusted odds ratios, 95% confidence intervals: 2.3 (1.1-5.2) and 28.1 (10.4-75.6) for moderate and severe sunburn, respectively). CONCLUSION Multiple solar lentigos on the upper back and shoulders of adults are potential clinical markers of past severe sunburn which may thus be used to identify a population at higher risk of developing cutaneous malignant melanoma.

Abstract
Individuals with melanocortin 1 receptor (MC1R) gene variants have been shown to carry an increased risk for the development of melanoma. In this study, we investigated the relationship of MC1R gene variants and the risk of melanoma in 123 melanoma patients and 155 control subjects from Greece. The entire MC1R gene was sequenced for polymorphisms and the results were correlated with host factors and pigmentary characteristics. MC1R polymorphisms were present in 59.4% of melanoma patients compared to 37.5% of controls, yielding an odds ratio (OR) of 2.43 (95% confidence interval (CI) = 1.50-3.96, P < 0.001) for melanoma among MC1R carriers. The risk of melanoma was enhanced in individuals carrying multiple variant alleles (OR = 6.97; 95% CI = 1.86-26.12, P = 0.004). Only the Val60Leu, Arg142His, and Arg151Cys variants were significantly associated with melanoma risk. In stratified analysis, the risk of melanoma among MC1R carriers was not influenced by skin phototype, skin color, or hair color. No association was found between MC1R genotype and the age of onset of melanoma, the tumor location, or the tumor thickness. In conclusion, MC1R polymorphisms are a predisposing factor of melanoma in a southern European population with a relatively low incidence of the disease.

Abstract
The risk of cutaneous malignant melanoma (CMM) is strongly associated with total number of nevi. Scanty information is available on the association between CMM at a specific anatomical site and number of nevi at the same site. We analyzed data from a case-control study conducted in Italy between 1992 and 1994, on 542 cases of CMM and 538 hospital controls. Cases and controls were examined by trained dermatologists who counted the number of melanocytic nevi. We derived multivariate odds ratios (ORs) and 95% confidence intervals (95% CIs) of site-specific risk of CMM for high versus low number of nevi at the corresponding site. The ORs of CMM for the highest versus the lowest tertile of number of nevi at the corresponding site was 1.4 (95% CIs: 0.7-2.8) at face and neck, 2.3 (95% CIs: 1.1-4.9) at anterior trunk, 4.9 (95% CIs: 2.9-8.4) at posterior trunk, 2.9 (95% CIs: 1.2-6.6) at upper limbs and 5.0 (95% CIs: 2.9-8.5) at lower limbs. In a case-case analysis, comparing CMM cases at a specific site and CMM cases at all other sites, the only excess risk was found for the posterior trunk, the ORs being 2.1 (95% CIs: 1.2-3.6) for the highest versus the lowest tertile of number of nevi. Our data do not support the hypothesis of a specific effect of nevi at each single anatomical site.

Abstract
BACKGROUND For Greece, no data regarding the incidence of cutaneous melanoma (CM) have been reported. In this report, we present epidemiologic data for CM on Crete, an island in southern Greece, during the years 1999-2002. We attempt a comparison with corresponding data reported for the Italian population. METHODS One hundred and two CM patients of Cretan origin with primary CM first diagnosed between the years 1999-2002 were interviewed and underwent complete skin examination by the same two experienced dermatologists. Crude and/or age-standardized incidence rates were calculated for Crete as a whole, as well as for each one of the four prefectures of the island. RESULTS The age-standardized incidence rate according to the Greek population was 4.6 per 100,000 person-years for men and 4.7 per 100,000 person-years for women. The crude incidence rates did not differ significantly between the four prefectures. Significant differences between Cretan and Italian CM patients were found in terms of gender, age at diagnosis, anatomic site and histogenetic type of CM, hair color, skin reaction to sun exposure, history of sunburn before the age of 15 years, presence of solar lentigines, and total common nevus count. CONCLUSIONS The incidence of CM on Crete is higher than that estimated for the whole of Greece and comparable with the incidence reported for other southern European countries.

Abstract
Trends in cancer mortality in Switzerland were analysed over the period 1980-2001, on the basis of the World Health Organization database. Appropriately developed correction factors were utilized for the period before 1995, to allow for spurious trends introduced by the change between the 8th and the 10th revisions of the ICD. Steady declines in cancer mortality were observed, particularly from the mid-1980s onwards. Over the last decade, the fall in overall age-standardized (world standard) cancer mortality was 11.1% in men (from 158.1 in 1990-1991 to 140.6/100,000 in 2000-2001) and 7.6% in women (from 91.6 to 84.7/100,000), and the decline was larger in truncated rates from 35 to 64 years (-18.0 and -9.7%). In men, all major tobacco and alcohol neoplasms have declined until the late 1990s but have levelled off over the last few years, reflecting recent trends in alcohol and tobacco consumption. The fall in male lung cancer mortality was 20% over the last decade (from 42.9 to 34.3/100,000). In contrast, lung cancer mortality in women has steadily increased by 38% between 1981 and 1991 and by 47% between 1991 and 2001, to reach 10.7/100,000 at all ages and 18.3 at age 35 to 64, due to increased prevalence of smoking in subsequent generations of Swiss women. Other sites showing substantial declines include stomach and colorectum in both sexes, (cervix) uteri and breast in women. Likewise, prostate cancer showed modest favourable trends after 1995. Steady declines were observed for leukaemias, Hodgkin's disease and testicular cancer, namely, the neoplasms most influenced by therapeutic improvements, while trends in lymphomas and myeloma showed no clear pattern.

Abstract
Several studies have investigated the effect of various anthropometric factors on the risk of cutaneous malignant melanoma (CMM). As the results are controversial, we analysed this issue in a case-control study conducted in Italy. The roles of several body size measures were investigated in a hospital-based case-control study of CMM conducted in Italy. The cases were 542 patients with CMM and the controls were 538 subjects admitted to the same hospitals as the cases for non-dermatological and non-neoplastic diseases. The odds ratios for the highest versus the lowest quartile were 2.06 [95% confidence interval (CI), 1.39-3.05] for weight, 1.16 (95% CI, 0.80-1.68) for height, 1.90 (95% CI, 1.28-2.80) for the body mass index (BMI) and 1.87 (95% CI, 1.28-2.72) for the body surface area (BSA). When allowing for BMI and BSA in the same model, the odds ratios were 1.55 (95% CI, 0.92-2.62) for BMI and 1.41 (95% CI, 0.85-2.33) for BSA. The present findings confirm that obesity increases the risk of CMM. BSA is also related to the risk of CMM. In terms of the population attributable risk, overweight and obesity would account for 31% of the cases of CMM in this Italian population, indicating the scope of prevention.

Abstract
Childhood melanoma is a rare but potentially fatal disease that is important to include in the differential diagnosis of any pigmented lesion in a child. The best prognosis is achieved with early diagnosis and definitive surgical excision. Adjuvant chemotherapy and immunotherapy are options for those with more advanced tumors. Melanoma in children must be treated as aggressively as in adults because childhood melanoma may be equally devastating.
