AIMS OF THE STUDY: Nonmelanoma skin cancer (NMSC) is the most common cancer in Switzerland and Europe. The main causative factor is exposure to ultraviolet radiation, which puts outdoor workers in general at a higher risk of developing NMSC than indoor workers. However, few studies have clinically examined the risk of developing NMSC to outdoor workers, especially mountain guides. We aimed to investigate the prevalence of NMSC and corresponding precancerous lesions, and the associated risk behaviour of mountain and ski guides in order to develop future prevention programmes...

The E2F1 transcription factor plays key roles in skin homeostasis. In the epidermis, E2F1 expression is essential for normal proliferation of undifferentiated keratinocytes, regeneration after injury and DNA repair following UV radiation-induced photodamage. Abnormal E2F1 expression promotes nonmelanoma skin carcinoma. In addition, E2F1 must be downregulated for proper keratinocyte differentiation, but the relevant mechanisms involved remain poorly understood. We show that differentiation signals induce a series of post-translational modifications in E2F1 that are jointly required for its downregulation...

Several epidemiological studies have evaluated the associations between coffee consumption and the risk of skin cancer; however, the results were not conclusive. This systematic review and meta-analysis of the cohort and case-control studies was carried out to determine the association between coffee intake and the risk of nonmelanoma skin cancer. Studies were identified by searching the PubMed and MEDLINE databases (to November 2015). Study-specific risk estimates were pooled under the random-effects model...

BACKGROUND: Though scientifically undisputed, cutaneous syncarcinogenesis is not reflected in German occupational disease (OD) regulations, which tend to be guided by the tenet of monocausality. Recognition of nonmelanoma skin cancer (NMSC) and its precursor lesions as OD requires individual assessment as to whether the requirements pursuant to either OD 5103 (occupational exposure to natural UV radiation) or OD 5102 (occupational exposure to polycyclic aromatic hydrocarbons) are fulfilled...

The use of biologics such as anti-tumor necrosis factor and oral Janus kinase inhibitors have revolutionized the treatment of rheumatoid arthritis (RA). The risk of malignancies such as lymphomas, lung cancer, and nonmelanoma skin cancers (NMSCs) is greater in patients with RA compared with the general population. The incidence of all malignancy (excluding NMSC) was similar in tofacitinib users compared with the general population. The rates of overall and site-specific malignancies in patients with RA treated with tofacitinib are similar to what is expected in the RA population and not different from disease-modifying antirheumatic drugs and biologics...

Objective: Mohs micrographic surgery is widely utilized for the treatment of nonmelanoma skin cancers with the advantage of tissue sparing and higher cure rate. The preoperative tumor size and post-Mohs micrographic surgery defect size are useful surrogate measures of nonmelanoma skin cancer morbidity. The authors sought to evaluate whether gender, Hispanic ethnicity, socioeconomic status, sun-safe practices and self-skin exams affected tumor size and Mohs micrographic surgery defect size. They also investigated factors associated with self-skin exams...

BACKGROUND: Mohs micrographic surgery examines all margins of the resected sample and has a 99% cure rate. However, many nonmelanoma skin cancers (NMSCs) are not readily amenable to Mohs micrographic surgery. This defines an unmet clinical need to assess the completeness of non-Mohs micrographic surgery resections during surgery to prevent re-excision/recurrence. OBJECTIVE: We sought to examine the utility of quenched activity-based probe imaging to discriminate cancerous versus normal-appearing skin tissue...

Non-melanoma skin cancer (NMSC) is a major health problem in Australia and the incidence is steadily increasing ((1).) However, the age standardized mortality rate (ASMR) for the entire population has not increased since 1996 ((2)) . One possible reason for this discrepancy is that the Australian population has greatly changed in the last 30 years with many people at low risk for skin cancer have migrated to Australia ((3).) Unless an adjustment is made for the population change, the data will show that the ASMR is stabilizing...

BACKGROUND: Basal cell carcinoma (BCC) is the most common nonmelanoma skin cancer. There is a clear association between BCC development and ultraviolet (UV) radiation. Erythropoietic protoporphyria (EPP) is an inherited porphyria disorder that is a result of protoporphyrin accumulation, typically manifesting with phototoxicity. CASE SUMMARY: We report a case of a 24 year-old man with both EPP and BCC diagnoses. At the age of 4 years, the patient was diagnosed with EPP...

Background: Heparanase is an enzyme that cleaves heparan sulfate chains. Oligosaccharides generated by heparanase induce tumor progression. Basal cell carcinoma and squamous cell carcinoma comprise types of nonmelanoma skin cancer. Objectives: Evaluate the glycosaminoglycans profile and expression of heparanase in two human cell lines established in culture, immortalized skin keratinocyte (HaCaT) and squamous cell carcinoma (A431) and also investigate the expression of heparanase in basal cell carcinoma, squamous cell carcinoma and eyelid skin of individuals not affected by the disease (control)...

Prostate cancer (PC) is a major disease that affects men's health worldwide. It is the second most common form of cancer in men, surpassed only by nonmelanoma skin cancers such as basal and squamous cell carcinomas. Diagnostic strategies with population screening for prostate cancer using prostate-specific antigen (PSA) has been surrounded with controversy and debated intensively ever since the PSA protein was first purified in 1979 by Wang et al. At the same time, advances in diagnostic imaging, surgery, radiation, and chemotherapy have increased the opportunity to effectively diagnose, treat, and manage PC...

The response of the skin to harmful environmental agents is shaped decisively by the status of the immune system. Keratinocytes constitutively express and secrete the chemokine-like mediator, macrophage migration inhibitory factor (MIF), more strongly than dermal fibroblasts, thereby creating a MIF gradient in skin. By using global and epidermis-restricted Mif knockout mice (Mif(-/-) and K14-Cre(+/tg); Mif(fl/fl)), we found that MIF both recruits and maintains antigen-presenting cells in the dermis/epidermis...

AIM OF DATABASE: The Danish Nonmelanoma Skin Cancer Dermatology Database was established in 2008. The aim of this database was to collect data on nonmelanoma skin cancer (NMSC) treatment and improve its treatment in Denmark. NMSC is the most common malignancy in the western countries and represents a significant challenge in terms of public health management and health care costs. However, high-quality epidemiological and treatment data on NMSC are sparse. STUDY POPULATION: The NMSC database includes patients with the following skin tumors: basal cell carcinoma (BCC), squamous cell carcinoma, Bowen's disease, and keratoacanthoma diagnosed by the participating office-based dermatologists in Denmark...

REVIEW
Hallvard Holdaas, Paolo De Simone, Andreas Zuckermann
Malignancy after solid organ transplantation remains a major cause of posttransplant mortality. The mammalian target of rapamycin (mTOR) inhibitor class of immunosuppressants exerts various antioncogenic effects, and the mTOR inhibitor everolimus is licensed for the treatment of several solid cancers. In kidney transplantation, evidence from registry studies indicates a lower rate of de novo malignancy under mTOR inhibition, with some potentially supportive data from randomized trials of everolimus. Case reports and small single-center series have suggested that switch to everolimus may be beneficial following diagnosis of posttransplant malignancy, particularly for Kaposi's sarcoma and nonmelanoma skin cancer, but prospective studies are lacking...
