Background: Despite its increased incidence and status as the most prevalent cancer in Canada, there is a paucity of epidemiological data on non-melanoma skin cancer (NMSC). Objective: To assess trends of keratinocyte carcinomas (KC) in Canada over 5 decades. Methods: Articles published from 1960 to 2015 on NMSC in Canada were identified through MEDLINE. Six articles met our search criteria. Results: Overall, KC has increased. However, the rate of increase in the past decade has slowed down and decreased in younger age cohorts. Men had higher incidences of KC. In both sexes, the basal cell carcinoma and squamous cell carcinoma ratio was ≥2.5:1. Keratinocyte carcinomas were most commonly located on the head and neck, and increasing rates are occurring on the trunk. Limitations: The methods of registering skin cancer cases vary among different provinces. Conclusion: Keratinocyte carcinomas incidence is overall increasing; however, there may be evidence that the incidence is leveling off and decreasing in younger age cohorts.

Skin cancer is one of the most frequently diagnosed malignancies worldwide and its incidence constantly increases. The disease divides in two major subtypes: non-melanoma and melanoma skin cancer. The main drawbacks of the traditional skin cancer therapy are primary and acquired drug resistance and serious side effects due to the nonspecific treatments targeting. Despite advances in therapy strategies there is a need of new affordable natural anti-skin cancer agents, which to possess higher efficiency without causing detrimental side effects. Medicinal plants provide great possibility for the discovery of new anticancer therapeutics with preventive and treatment potential. Cotinus coggygria Scop. is a plant species widely applied in phytotherapy predominantly against disorders of the skin and mucosal tissues. The herb has a large range of valuable biological activities but its anticancer properties have not been thoroughly studied. The aim of the present research was to assess the antiproliferative properties of the crude leaf aqueous ethanolic extract from Bulgarian herb C. coggygria and its chloroformic and aqueous fractions on a panel of human skin cancer cell lines: basal cell carcinoma (TE 354.T), squamous cell carcinoma (A431) and malignant melanoma (A375) and to compare them to the cell growth inhibitory potential on normal dermal cell line (BJ). The antiproliferative capacity of the plant substances was investigated using MTT assay and microscopy cell morphology observation after 72 h cell treatment in a wide scale of concentrations. The obtained results showed that the crude extract and both fractions inhibit significant proliferation of A431 squamous cell carcinoma and A375 melanoma cells with the highest cytostatic effect registered for the aqueous fraction on A375 cells with a half maximal inhibitory concentration value of 44.33 ?g/ml. C. coggygria exhibited no cytostatic activity towards TE 354.T basal cell carcinoma cells. The established marked slight

Background: Skin cancer is a broad term that refers to a variety of different types of cancer. It is usually recognized as non-melanoma and melanoma skin cancer. In many parts of the world, the prevalence is high, with significant ecological and ethical variation. Objectives: Objective was to determine demographic and histological features of skin cancer in Southwest region of Pakistan. Methodology: This retrospective study was carried out on skin cancer 1169 cases of Centre for Nuclear Medicine and Radiotherapy (CENAR) in Quetta. The data from January 2000 to December 2009 (10Years) was retrieved from record. The aim was to determine the importance of skin cancer in this area, its gender wise distribution and its pathological types. Results: Record of total 9308 cancer patients was retrieved from patients presenting to CENAR Quetta. From 9308 case, 1169(12.5%) patients were of skin cancer which was second most prevalent category of cancer in this area. Prevalence was higher in males with 713(61%) cases as compared to females. Pathologically with 634(54%) cases, the most prevalent category was Squamous cell carcinoma (SCC). Conclusion: Skin cancer is wide-spread type of cancer in patients of south-west region of Pakistan. The findings of this study are not aligned with published data. The difference is because of high altitude of the study area, dry climate and long skin exposure particularly in low socio-economic field workers.

Sun Exposure

Background: The development of knowledge concerning the role of sun exposure in causing skin cancer has been a gradual one. Objective: This article reviews the article by Urbach who used manikin coated with an ultraviolet dosimeter to see exactly where on the head and neck the exposure was greatest. Conclusion: Urbach showed that the areas of greatest sun exposure on his manikins corresponded with the location of 95% of squamous cell carcinoma and 66% of basal cell carcinoma. He also clearly showed the importance of scattered sky and reflected radiation.

Background/Aim: Non-melanoma skin cancer is the most common cancer in the world. Somatic mutations in the TP53 gene are associated with the development of this cancer. To describe mutations in exons 5-8 of the TP53 gene in a sample of Colombian patients with non-melanoma skin cancer. Materials and Methods: One hundred and fifteen patients with non-melanoma skin cancer were included. Exons 5-8 were amplified and analyzed by PCR-High Resolution Melting and Sanger sequencing. Results: Fifty-seven patients with basal cell carcinomas and 58 with squamous cell carcinomas were studied. 16% of patients with basal cell carcinoma and 26% of patients with squamous cell carcinoma had mutations in the TP53 gene. The most frequent mutations were substitutions, while three patients had deletions. The most frequent mutation was p.R158G. Conclusion: The analysis showed that Colombian individuals with non-melanoma skin cancer have genetic TP53 variants different from those reported as recurrent for this disease.
