Currently, imaging technologies that enable dermsurgeons to visualize non-melanoma skin cancers (NMSC) in vivo preoperatively are lacking, resulting in excessive or incomplete removal. Multispectral optoacoustic tomography (MSOT) is a volumetric imaging tool to differentiate tissue chromophores and exogenous contrast agents, based on differences in their spectral signatures and used for high-resolution imaging of functional and molecular contrast at centimeter scale depth. We performed MSOT imaging with two- and three-dimensional handheld scanners on 21 Asian patients with NMSC...

BACKGROUND: Adenocarcinoma (AC) is the most common lung cancer among non-smokers, but few studies have assessed the effect of PM2.5 on AC among never smokers. The purpose of this study was to assess the association between ambient PM2.5 and incident lung AC in the Adventist Health and Smog Study-2 (AHSMOG-2), a cohort of 80,044 non-smokers (81% never smokers) followed for 7.5 years (597,177 person-years) (2002-2011). METHODS: Incident lung AC was identified through linkage with U...

<p>Introduction: Nonmelanoma skin cancer (NMSC) is the most common malignancy in the US Primary prevention of NMSC with physical photoprotective measures are often not sufficient to impact skin cancer incidence in high-risk individuals. Chemoprevention is the use of agents to prevent, suppress, and reverse carcinogenic progression. Many agents have been investigated, but preclinical and clinical studies are often inconsistent.</p> <p>Methods: A cross-sectional study was designed to assess current practices, perceptions, and general knowledge of U...

Tetracyclines (TCNs) are commonly used in the management of several chronic dermatological disorders, partly due to their affinity for inflamed skin tissue, as they are known to suppress cytokines including tumor necrosis factor-alpha and interleukin-6 that are typically involved in inflammatory skin disorders.(1) TCNs are known to be photoreactive following ultraviolet (UV) radiation exposure, a known risk factor for the development of nonmelanoma skin cancer (NMSC), notably basal cell carcinoma (BCC) and squamous cell carcinoma (SCC)...

BACKGROUND: NMSC is an occupational disease for outdoor workers in Germany since 2015. Sustainable prevention is demanded and sunscreen promoted as an effective tool. However, studies on the satisfaction of sunscreen users are rare. OBJECTIVE: To evaluate the satisfaction of mountain guides using a high SPF sunscreen product as an appropriate prevention tool for mountain guides. METHODS: Motivating mountain and ski guides in Germany to use very high protection sunscreen (SPF50+, Actinica Lotion) during a 4 to 8 hours workday followed by the completion of a self-filled paper-based questionnaire about their experience and satisfaction with the product...

Electronic Brachytherapy (EBT) has seen a significant rise in use over the past few years in treating non-melanoma skin cancer (NMSC). However, the current literature in EBT remains scarce. Existing data on high dose rate brachytherapy (HDR-BT) with surface applicators is often used to justify its efficacy and safety. In this review we study the two treatment modalities on their efficacy in treating NMSC and we explore the reasons behind the recent uprise in EBT. A literature review using PubMed was performed for articles published until January 2017 studying efficacy of HDR-BT and EBT for treating NMSC...

BACKGROUND AND OBJECTIVE: Nonmelanoma skin cancer (NMSC) is the most common human cancer. Because these tumors often affect the face, there is a strong need for both accurate removal of these neoplasms to prevent recurrence and maximal tissue preservation to prevent cosmetic or functional deformity. Polarization-enhanced reflectance and fluorescence imaging (PERFI) is a new bedside method that uses fluorescent chromophores to image NMSC. While the feasibility of the technique has been successfully demonstrated in ex vivo studies, this is the first pilot study to extend the use of PERFI to in vivo intraoperative imaging of NMSC...

The skin represents a pivotal organ for the human body's vitamin D endocrine system, being both the site of ultraviolet (UV)-B-induced vitamin D synthesis and a target tissue for the pluripotent effects of 1,25(OH)2D3 and other biologically active vitamin D metabolites. As many other steroid hormones, 1,25(OH)2D3 exerts its effects via two independent signal transduction pathways: the classical genomic and the non-genomic pathway. While non-genomic effects of 1,25(OH)2D3 are in part exerted via effects on intracellular calcium, genomic effects are mediated by the vitamin D receptor (VDR)...

Chronic inflammatory conditions, such as psoriasis, may pose an increased risk of cancer due to impaired immunosurveillance resulting from chronic inflammation and immunosuppressive medications. To compare the risk of non-melanoma skin cancer (NMSC) in a retrospective cohort of 72,739 psoriasis patients and 25,956 non-dermatological patients. A record linkage was performed for data on hospitalizations, and the occurrence of NMSC was compared by computing the relative risk (RR) and modelled using multiple logistic regression...

Vitamin D synthesis takes place in the skin due to solar ultraviolet-B (UVB) radiation. Several studies have shown the association between low sun exposure, non-melanoma skin cancer (NMSC) and a lack of vitamin D synthesis. Since such synthesis in the body depends on the exposure of the skin to solar UVB radiation (290-320 nm), experimental measurements of this type of solar radiation are important. Tarapaca University in Arica, Chile, established a solar UV radiation laboratory in 2006 and since then this laboratory has performed systematic experimental solar UVB measurements using a calibrated biometer instrument...

Skin cancer, including melanoma and non-melanoma skin cancer (NMSC), represents the most common type of malignancy in the white population. The incidence rate of melanoma is increasing worldwide, while the associated mortality remains stable, or is slightly decreasing. On the other hand, the incidence for NMSC varies widely, with the highest rates reported in Australia. In the current review, we highlight recent global trends in epidemiology of skin cancer. We discuss controversial issues raised in current epidemiological data, we analyze the most important risk factors associated with the development of melanoma and NMSC and the impact of skin cancer on health care services...

Nonmelanoma skin cancer (NMSC) is the most common malignancy in the United States representing a considerable public health burden. Pharmacological suppression of skin photo-carcinogenesis has shown promise in preclinical and clinical studies, but more efficacious photochemopreventive agents are needed. Here, we tested feasibility of harnessing pharmacological disruption of intracellular zinc-homeostasis for photochemoprevention in vitro and in vivo. Employing the zinc-ionophore and FDA-approved microbicidal agent zinc pyrithione (ZnPT), used worldwide in over-the-counter (OTC) topical consumer products, we first demonstrated feasibility of achieving ZnPT-based intracellular Zn(2+) -overload in cultured malignant keratinocytes (HaCaT-ras II-4; SCC-25) employing membrane-permeable fluorescent probes...

BACKGROUND: Skin cancer has reached epidemic proportions, with more new cases diagnosed annually than the combined incidence of cancers of the breast, prostate, lung, and colon. Estimates show 2 to 3 million new cases of non-melanoma skin cancer (NMSC) every year, and, among women, it is the young (younger than 45 years) who are disproportionately affected. OBJECTIVE: This article aims to address questions and concerns pertinent to skin cancer in a woman-centric way...

Increasing incidence rates (IR) of non-melanoma skin cancer (NMSC) in Caucasian populations have been described worldwide. Cancer registry data from the Saarland and Schleswig-Holstein Federal States were used to analyze incidence and mortality trends in Germany. Age-standardized rates are compared to crude rates to assess disease burden. Joinpoint regression models were used to estimate annual percentage changes and 95% confidence intervals, allowing us to assess temporal trends between 1970-2012. Incidence predictions until 2030 were based on age-period-cohort models and linear extrapolation techniques...

BACKGROUND: Squamous cell carcinomas and basal cell carcinomas are both induced by chronic UV exposure. However, their predilection for specific areas of the face remains unexplained. Regional factors such as arterial blood flow may explain specific tumor localization. OBJECTIVE: To determine whether in the fronto-temporal area of the face there is a preferential localization of non-melanoma skin cancer (NMSC) at sites of arterial blood vessels. METHODS: Twenty-two patients with NMSC of the fronto-temporal area were selected for this study...

BACKGROUND: Non-melanoma skin cancer (NMSC) was officially recognized in 2015 as an occupational disease for outdoor workers in Germany. Together with the enormous socioeconomic impact of NMSC, this has led to the continuous demand of evidence-based prevention. However, studies assessing the perceptions and beliefs along with risk behavior of outdoor workers as an essential prerequisite for prevention are rare. OBJECTIVE: To assess perceptions, beliefs, barriers, risk and preventive behavior towards non-melanoma skin cancer among different outdoor groups as a basis for the development of sustainable prevention programs...

Non-melanoma skin cancers (NMSC) mainly comprise two different entities: basal cell carcinoma (BCC) and squamous cell carcinoma (SCC); beneath these two entities, Merkel cell carcinoma, adnexal tumors, dermatofibrosarcoma protuberans, angiosarcoma, and cutaneous lymphoma belong to NMSC. These rare skin tumors are not the topic of this review. BCC and SCC are the most common cancers diagnosed in humans. The preferred treatment is surgery, which in most cases is curative. Although a high recurrence rate is seen, these cancers rarely metastasize...
