BACKGROUND: Application of deep-learning technology to skin cancer classification can potentially improve skin cancer screening sensitivity and specificity, but the number of training images required for such system is thought to be extremely large. OBJECTIVE: To determine if deep-learning technology could be used to develop an efficient skin cancer classifying system with a relatively small dataset of clinical images. METHODS: A deep convolutional neural network (DCNN) was trained using a dataset of 4867 clinical images obtained from 1842 patients diagnosed with skin tumors at the University of Tsukuba Hospital from 2003 to 2016...

Screening for melanoma may save lives, but may also cause patient distress. One key reason that preventative visual skin examinations for skin cancer are not currently recommended is the inadequate available evidence to assess potential harm to psychosocial wellbeing. We investigated potential psychological harms and benefits of skin examinations by conducting telephone surveys in 2015 of 187 screened participants; all were ≥35 years old. Participants had their skin examined by practitioners who had completed INFORMED, a validated web-based training for detection of skin cancers, particularly melanoma...

BACKGROUND: Outdoor professionals such as mountain guides are at a substantial risk of developing non-melanoma skin cancer (NMSC) due to solar ultraviolet radiation (UVR) exposure. Despite major recent primary prevention efforts, studies on secondary skin cancer prevention efforts are limited and corresponding data on outdoor workers scarce. OBJECTIVE: To assess the sun-protective behavior and individual motivations for or against skin cancer screening examinations in the German mountain guide population to aid in the development of effective awareness and prevention strategies...

BACKGROUND: One of the main risk factors for non-melanoma skin cancer (NMSC), the most common cancer worldwide, is solar ultraviolet radiation (UVR). This has led to the recognition of NMSC as occupational disease for outdoor workers in several countries. However, outdoor professions are a very heterogeneous group with diverse daily activities and associated UVR exposure. OBJECTIVE: To compare the prevalence of NMSC and associated risk behaviour in different outdoor professions...

The United States Preventive Services Task Force (USPSTF) 2016 recommendation for skin cancer screening in asymptomatic healthy adults concluded that current evidence is "insufficient to assess the balance and harms of visual skin examination." One contributing factor leading to the insufficient grade was a concern for cosmetic harms resulting from unnecessary biopsies or excisions. This commentary briefly highlights the pertinent studies and currently accepted methods for pigmented lesion biopsy...

Outdoor recreation can lead to substantial sun exposure. Employees of outdoor recreation establishments with extended time outdoors have amplified cumulative exposure to ultraviolet (UV) radiation and an increased risk of skin cancer. The "Sun Safe on the Slopes" program was created by Huntsman Cancer Institute at the University of Utah and the Utah Cancer Action Network to address increased UV exposure and skin cancer risk with free skin cancer screenings, outreach, and prevention education to local ski resorts...

INTRODUCTION: Cutaneous cancers are very common, easily visible on skin. The general practitioner (GP) is in the front line to manage the lesions. He has to recognize malignancy and refer most often to the specialist for excision, or consider that the lesion is benign and in ambiguous cases, offer clinical monitoring. The current low medical density in the Centre Val de Loire area makes access to general practitioners (GP) and dermatologists harder. The aim of this study was to evaluate GPs' everyday practice in cutaneous cancers screening in general, and particularly in melanoma screening, in a rural region of France...

Nail-patella syndrome (NPS) is a rare autosomal-dominant disorder characterized by the classic triad of fingernail dysplasia, patellar absence/hypoplasia, and presence of iliac horns. We describe the various features of NPS, focusing on dermatologic and musculoskeletal findings. A 69-year-old man presented to the dermatology clinic for a routine skin cancer screening. Physical examination revealed hypoplastic fingernails with longitudinal ridging, splitting, and triangular lunulae; left patellar absence and right patellar hypoplasia; and bilateral iliac horns that had been present since birth...

Polychlorinated biphenyls (PCB) are well known persistent and toxic environmental pollutants. Our aim was to identify effects of moderate-high exposure to dioxin-like (dl) and non-dioxin-like (ndl)-PCBs on the skin in order to provide more insight in the pathophysiological effects of these compounds. We performed a dermatological examination on 92 former workers from a transformer recycling company with known elevated serum PCB and/or dioxin (polychlorinated dibenzo-p-dioxin/polychlorinated dibenzo-p-furan (PCDD/F)) levels...

Ultraviolet (UV)-induced DNA lesions are almost exclusively removed by the nucleotide excision repair (NER) pathway, which is essential for prevention of skin cancer development. Patients with xeroderma pigmentosum (XP) are extremely sun sensitive due to a genetic defect in components of the NER cascade. They present with first signs of premature skin aging at an early age, with a considerably increased risk of developing UV-induced skin cancer. XP belongs to the group of DNA repair defective disorders that are mainly diagnosed in the clinic and in hindsight confirmed at the molecular level...

REVIEW
Marie Christine Martens, Christina Seebode, Janin Lehmann, Steffen Emmert
UV radiation is acknowledged as the primary cause of photocarcinogenesis and therefore contributes to the development of skin cancer entities such as squamous cell carcinoma (SCC), basal cell carcinoma (BCC), and melanoma. Typical DNA photoproducts and indirect DNA damage caused by reactive oxygen species are the result of UV radiation. UV-induced DNA damage is repaired by nucleotide excision repair, which consequently counteracts the development of mutations and skin carcinogenesis. Tumour-suppressor genes are inactivated by mutation and growth-promoting pathways are activated leading to disruption of cell-cycle progression...

A new multimodal system for rapid, noninvasive in vivo skin cancer screening is presented, combining optical coherence tomography (OCT) and optoacoustic (OA) modalities to provide precise tumor depth determination with a Raman spectroscopic modality capable of detecting the lesion type and, thus, providing diagnostic capability. Both OA and Raman setups use wide field skin illumination to ensure the compliance with maximum permissible exposure (MPE) requirements. The Raman signal is collected via the OCT scanning lens to maximize the signal-to-noise ratio of the measured signal while keeping radiation levels below MPE limits...

BACKGROUND: Azathioprine and 6-mercaptopurine (thiopurines) are common adjunct treatments for inflammatory bowel disease (IBD). Although thiopurine therapy in organ transplant recipients is known to increase nonmelanoma skin cancers (NMSCs), dermatologic literature yields less data regarding NMSC risk of thiopurine use in IBD. OBJECTIVE: The aim of this study was to systematically review current literature on NMSC risk in patients with IBD using thiopurine therapy...
