Abstract
Melanoma is potentially curable if diagnosed at its earliest stages and treated properly. The best approaches for reducing deaths due to melanoma are primary and secondary prevention. The objective of this study is to evaluate patient awareness of the risk factors for developing melanoma and attitudes toward its prevention. Also, this study aims to assess observance of recommended preventive measures and to identify possible factors associated with a low adoption of these measures. This cross-sectional study based on an online questionnaire included 185 consecutively enrolled subjects at risk of developing melanoma monitored in a pigmented lesion unit in Valencia (Spain). Level of knowledge, attitude, and observance of preventive measures were evaluated. Statistical analysis was carried out using contingency tables, chi-squared test, and Spearman correlation. Out of those who reported practicing skin self-examination, only 24.1 % performed it in the optimal way. A better attitude was observed in low-risk patients (r = -0.28, p < 0.01). Being female (p < 0.01), aged 18-35 (p = 0.02), fair-haired (p = 0.02), having skin phototype I-II (p < 0.01), and a suitable attitude (p = 0.05) and knowledge (p < 0.01) were related to a better use of sunscreens and avoidance of sun exposure. Knowledge was inversely associated with age (p = 0.01). Despite the high level of knowledge and positive attitude, inadequate practice of compliance with recommended primary and secondary preventive measures was observed in our risk population.

Abstract
INTRODUCTION In patients with primary cutaneous melanoma, there is generally a delay between excisional biopsy of the primary tumour and sentinel-node biopsy. The objective of this study is to analyse the prognostic implications of this delay. PATIENTS AND METHOD This was an observational, retrospective, cohort study in four tertiary referral hospitals. A total of 1963 patients were included. The factor of interest was the interval between the date of the excisional biopsy of the primary melanoma and the date of the sentinel-node biopsy (delay time) in the prognosis. The primary outcome was melanoma-specific survival and disease-free survival. RESULTS A delay time of 40 days or less (hazard ratio (HR), 1.7; confidence interval (CI), 1.2-2.5) increased Breslow thickness (Breslow ⩾ 2 mm, HR, > 3.7; CI, 1.4-10.7), ulceration (HR, 1.6; CI, 1.1-2.3), sentinel-node metastasis (HR, 2.9; CI, 1.9-4.2), and primary melanoma localised in the head or neck were independently associated with worse melanoma-specific survival (all P < 0.03). The stratified analysis showed that the effect of delay time was at the expense of the patients with a negative sentinel-node biopsy and without regression. CONCLUSION Early sentinel-node biopsy is associated with worse survival in patients with cutaneous melanoma.

Abstract
A high growth rate in melanomas has been associated with a more aggressive phenotype and worse survival. The aim of this study was to define the dermoscopic characteristics associated with this type of cutaneous melanoma. We carried out a retrospective study of 132 cutaneous melanomas, analyzing certain clinical characteristics and the most important dermoscopic variables related to the melanomas. Fast-growing melanomas were considered to be those with a growth rate of more than 0.5 mm per month. Fast-growing melanomas more often lacked an atypical network, were symmetrical, presented ulceration, and were hypopigmented. The dermoscopic vascular pattern often showed atypical irregular vessels and milky-red areas. The association of these two is a specific characteristic. Fast-growing melanomas have a characteristic phenotype and dermoscopy can be useful for their identification.

Abstract
INTRODUCTION Familial history of melanoma is a well-known risk factor for the disease, and 7% melanoma patients were reported to have a family history of melanoma. Data relating to the frequency and clinical and pathological characteristics of both familial and non-familial melanoma in Spain have been published, but these only include patients from specific areas of Spain and do not represent the data for the whole of Spain. PATIENTS AND METHODS An observational study conducted by the Spanish Group of Melanoma (GEM) analyzed the family history of patients diagnosed with melanoma between 2011 and 2013 in the dermatology and oncology departments. RESULTS In all, 1047 patients were analyzed, and 69 (6.6%) fulfilled criteria for classical familial melanoma (two or more first-degree relatives diagnosed with melanoma). Taking into account other risk factors for familial melanoma, such as multiple melanoma, pancreatic cancer in the family or second-degree relatives with melanoma, the number of patients fulfilling the criteria increased to 165 (15.8%). Using a univariate analysis, we determined that a Breslow index of less than 1 mm, negative mitosis, multiple melanoma, and a history of sunburns in childhood were more frequent in familial melanoma patients, but a multivariate analysis revealed no differences in any pathological or clinical factor between the two groups. CONCLUSIONS Similar to that observed in other countries, familial melanoma accounts for 6.6% of melanoma diagnoses in Spain. Although no differences in the multivariate analysis were found, some better prognosis factors, such as Breslow index, seem more frequent in familial melanoma, which reflect a better early detection marker and/or a different biological behavior.

Abstract
In an ongoing screen for DNA sequence variants that confer risk of cutaneous basal cell carcinoma (BCC), we conduct a genome-wide association study (GWAS) of 24,988,228 SNPs and small indels detected through whole-genome sequencing of 2,636 Icelanders and imputed into 4,572 BCC patients and 266,358 controls. Here we show the discovery of four new BCC susceptibility loci: 2p24 MYCN (rs57244888[C], OR=0.76, P=4.7 × 10−12), 2q33 CASP8-ALS2CR12 (rs13014235[C], OR=1.15, P=1.5 × 10−9), 8q21 ZFHX4 (rs28727938[G], OR=0.70, P=3.5 × 10−12) and 10p14 GATA3 (rs73635312[A], OR=0.74, P=2.4 × 10−16). Fine mapping reveals that two variants correlated with rs73635312[A] occur in conserved binding sites for the GATA3 transcription factor. In addition, expression microarrays and RNA-seq show that rs13014235[C] and a related SNP rs700635[C] are associated with expression of CASP8 splice variants in which sequences from intron 8 are retained. Basal cell carcinoma is a common cancer among people of European ancestry, with associated high economic costs to monitor and treat. Here Stacey et al. conduct a genome-wide association study on Icelandic and other European populations, identifying four novel loci associated with cancer susceptibility.

Abstract
BACKGROUND Melanoma is considered a heterogeneous tumor with genetic and environmental factors involved in its pathogenesis. The impact of these factors varies depending on age. OBJECTIVE The aim of this study was to characterize the epidemiological, phenotypic, and histological features of patients with melanoma according to three age groups: ≤40, 41-65, and >65 years. METHODS A total of 1122 consecutive patients with invasive melanoma definitively treated in our institution since January 2000 were selected from our melanoma database. Epidemiological, phenotypic, and histological data were retrieved and analyzed as a function of age. RESULTS Female patients predominated in the younger age group. The location of cutaneous malignant melanoma differed with age. In the younger and middle age groups, tumors presented mainly on the trunk, while in the older group they were mainly found on the head/neck. Signs of actinic damage such as actinic keratoses, solar lentigines, or other skin tumors increased with age, while genetic factors such as family history of melanoma or a high number of common melanocytic nevi were more frequent in the younger group. CONCLUSION Our results suggest that melanoma development in younger patients is the result of genetic factors, particularly related to multiple nevi, whereas in older patients environmental factors such as severe chronic sun exposure play a major role.

Abstract
This study aims to investigate the level of awareness on the risks related to sun exposure, attitude towards sun protection and sun protection behaviour in Spanish beachgoers. During the summer of 2009, trained assistants conducted a structured interview with 630 sunbathers at the beaches of Valencia, Spain, via administrating a questionnaire including the following: (a) general data (age, gender, education, profession), (b) "knowledge" and "attitude" items and (c) self-assessed sun sensitivity, sun exposure and sun protection characteristics. The health belief model was used to evaluate factors that may influence on engaging healthy behaviour. The median age was 30 (2-82) years; the M/F ratio was 0.60. Despite the widespread regular ("often" or "always", 80%) use of high (>15) sun-protective factor sunscreens, current recommendations on sun protection were not regularly followed, and a history of sunburns is very common (70%). At multivariate analysis, female gender, age, fair hair, freckles, all-day use of sunscreens and wearing sunglasses were independent factors associated with having sunburn history. A high knowledge and a fairly good attitude emerged (median scores, 6/7 and 22/30, respectively). Age class (p = 0.032), educational level (p < 0.0001), sunscreen use (p = 0.048) and adequate timing of the first application of sunscreens (p = 0.015) were predictors of awareness, while factors associated with a more favourable attitude were educational level (p < 0.0001) and regular use of hats (p = 0.001). Wrong beliefs mainly concern sunscreens (false safety); the attractiveness of a tanned look is the main unfavourable attitude. Physical and motivational barriers are common (80%). The findings by highlighting constitutional and psychosocial factors involved in unhealthy behaviour provide useful information to promote sun-safe interventions in this population.

Abstract
The MC1R gene is a key regulator of skin pigmentation. We aimed to evaluate the association between MC1R variants and the risk of sporadic cutaneous melanoma (CM) within the M-SKIP project, an international pooled-analysis on MC1R, skin cancer and phenotypic characteristics. Data included 5,160 cases and 12,119 controls from 17 studies. We calculated a summary odds ratio (SOR) for the association of each of the nine most studied MC1R variants and of variants combined with CM by using random-effects models. Stratified analysis by phenotypic characteristics were also performed. Melanoma risk increased with presence of any of the main MC1R variants: the SOR for each variant ranged from 1.47 (95%CI: 1.17-1.84) for V60L to 2.74 (1.53-4.89) for D84E. Carriers of any MC1R variant had a 66% higher risk of developing melanoma compared with wild-type subjects (SOR; 95%CI: 1.66; 1.41-1.96) and the risk attributable to MC1R variants was 28%. When taking into account phenotypic characteristics, we found that MC1R-associated melanoma risk increased only for darker-pigmented Caucasians: SOR (95%CI) was 3.14 (2.06-4.80) for subjects with no freckles, no red hair and skin Type III/IV. Our study documents the important role of all the main MC1R variants in sporadic CM and suggests that they have a direct effect on melanoma risk, independently on the phenotypic characteristics of carriers. This is of particular importance for assessing preventive strategies, which may be directed to darker-pigmented Caucasians with MC1R variants as well as to lightly pigmented, fair-skinned subjects.

Abstract
BACKGROUND Awareness of individual risk may encourage improved prevention and early detection of melanoma. METHODS We evaluated the accuracy of self-reported pigmentation and nevus phenotype compared with clinical assessment, and examined agreement between nevus counts from selected anatomical regions. The sample included 456 cases with invasive cutaneous melanoma diagnosed between ages 18 to 39 years and 538 controls from the population-based Australian Melanoma Family Study. Participants completed a questionnaire about their pigmentation and nevus phenotype, and attended a dermatologic skin examination. RESULTS There was strong agreement between self-reported and clinical assessment of eye color [κ, = 0.78; 95% confidence interval (CI), 0.74-0.81]; and moderate agreement for hair color (κ = 0.46; 95% CI, 0.42-0.50). Agreement between self-reported skin color and spectrophotometer-derived measurements was poor (κ = 0.12; 95% CI, 0.08-0.16) to moderate (Spearman correlation rs = -0.37; 95% CI, -0.32 to -0.42). Participants tended to underestimate their nevus counts and pigmentation; men were more likely to underreport their skin color. The rs was 0.43 (95% CI, 0.38-0.49) comparing clinical total body nevus counts with self-reported nevus categories. There was good agreement between total body nevus counts and site-specific nevus counts, particularly on both arms. CONCLUSIONS Young adults have suboptimal accuracy when assessing important risk characteristics including nevus numbers and pigmentation. Measuring nevus count on the arms is a good predictor of full body nevus count. IMPACT These results have implications for the likely success of targeted public health programs that rely on self-assessment of these factors.

Abstract
Approximately 10% of cutaneous malignant melanoma (CMM) cases occur in a familial setting and known high-penetrance melanoma susceptibility genes (CDKN2A, CDK4, BAP1, and TERT) account for melanoma susceptibility in a small proportion of melanoma-prone families. To identify additional high-penetrance susceptibility genes for familial CMM, we performed whole exome sequencing in 101 CMM cases/obligate carriers in 56 unrelated melanoma-prone families recruited from the Romagna area in Italy. We identified a germline founder mutation in Protection Of Telomeres 1(POT1) (g.7:124493086 C>T, p.S270N) in five unrelated melanoma-prone families. The mutation was also found in a single sporadic CMM case from Romagna out of 1,824 Italian cases examined, but it was not seen in public databases, our internal exome databases of over 1000 subjects, and 878 Spanish CMM cases and 3,489 controls (2,038 Italian and 1,451Spanish) genotyped. POT1 is a component of the telomeric shelterin complex that plays a critical role in maintaining telomere integrity and regulating telomere length. The p.S270N mutation is highly conserved among vertebrates and predicted to be deleterious by most computational programs we evaluated. Carriers of the p.S270N mutation had increased length and heterogeneity as well as increased average number of fragile telomeres in peripheral blood mononuclear cell (PBMC) DNA compared to age-matched CMM cases (controls) without the mutation. Exome sequencing analysis of Italian families also identified two other rare missense substitutions in POT1 (g.7:124464052 C>G [p.Q623H] and g.7:124503540 C>T [p.R137H]) that were found in all cases sequenced in two families. Both missense mutations are absent from public databases and 3,489 genotyped controls, and are predicted to be deleterious by most algorithms. The carriers of these two mutations showed slightly but significantly increased telomere intensity signals and telomere fragility in PBMCs compared to age-matched controls. We further sequenced POT1 exons in 768 CMM cases and 768 controls collected from Italy and we found that CMM cases showed a significant increase in the burden of rare exonic variants compared to controls (OR=5.4, 95% CI=1.5-29.2, P=0.0021). Subsequently, we identified two novel recurrent germline missense mutations in POT1 (g.7:124499043 C>T, p.D224N and g.7:124469308 C>G, p.A532P) in American and French familial melanoma cases. Our findings suggest that POT1 is a major susceptibility gene for familial melanoma in several populations and that genes involved in telomere maintenance may play important roles in melanoma development.

Abstract
Some recent studies have shown an association between sleep disordered breathing (SDB) and cancer mortality and incidence but no study has focused on a specific type of cancer. The objective of this study was to analyse the relationship between the severity of SDB and factors related to cutaneous malignant melanoma (CMM) aggressiveness. We performed a multicentre observational study in 82 consecutive patients diagnosed with CMM. 56 patients in whom melanoma measurements were available were finally included in the study. Melanoma measurements of aggressiveness included: tumour mitotic rate, Breslow index, presence of ulceration, stage of disease and growth rate of melanoma. A sleep study was performed in all the included patients. Multivariate analyses were used to examine the independent relationship between SDB severity (apnoea-hypopnea index (AHI) and nocturnal oxygen desaturation indexes (ODI3% and ODI4%)) and measures of CMM aggressiveness. 60.7% of patients had SDB (AHI ≥ 5) and 14.3% severe obstructive sleep apnoea (AHI ≥ 30). In fully adjusted multivariate analyses, AHI (OR 1.08, 95% CI 1.02-1.14), ODI3% (OR 1.08, 95% CI 1.02-1.11) and ODI4% (OR 1.1, 95% CI 1.02-1.2) were independently associated with an increased melanoma growth rate. Furthermore, AHI, ODI4% and ODI3% were significantly correlated with other aggressiveness factors of CMM, such as Breslow index, presence of ulceration and mitotic index. SDB severity markers are associated with some aggressiveness markers of CMM.
