Background Squamous cell carcinoma (SCC) is the second-most common form of non-melanoma skin cancer (NMSC). Objective To provide guidance to Canadian health care practitioners regarding management of SCCs. Methods Literature searches and development of graded recommendations were carried out as discussed in the accompanying introduction (chapter 1 of the NMSC guidelines). Results SCCs are sometimes confined to the epidermis, but they can also invade nearby tissues and, in some cases, metastasize to neighbouring lymph nodes or other organs. This chapter discusses the natural history, staging, prognosis, and management of SCC—a tumour type that is less common but typically more aggressive than BCC. For this reason, margin control is strongly preferred in treating SCCs. Conclusions Although approaches such as cryosurgery and radiation therapy may be considered for some patients, surgical excision—sometimes coupled with radiation—remains the cornerstone of SCC management. Patients with high-risk SCC may also be considered for referral to an appropriate multidisciplinary clinic.

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.

Reactive oxygen species (ROS) have been subject of increasing interest in the pathophysiology and therapy of cancers in recent years. In skin cancer, ROS are involved in UV-induced tumorigenesis and its targeted treatment via, e.g., photodynamic therapy. Another recent technology for topical ROS generation is cold physical plasma, a partially ionized gas expelling dozens of reactive species onto its treatment target. Gas plasma technology is accredited for its wound-healing abilities in Europe, and current clinical evidence suggests that it may have beneficial effects against actinic keratosis. Since the concept of hormesis dictates that low ROS levels perform signaling functions, while high ROS levels cause damage, we investigated herein the antitumor activity of gas plasma in non-melanoma skin cancer. In vitro, gas plasma exposure diminished the metabolic activity, preferentially in squamous cell carcinoma cell (SCC) lines compared to non-malignant HaCaT cells. In patient-derived basal cell carcinoma (BCC) and SCC samples treated with gas plasma ex vivo, increased apoptosis was found in both cancer types. Moreover, the immunomodulatory actions of gas plasma treatment were found affecting, e.g., the expression of CD86 and the number of regulatory T-cells. The supernatants of these ex vivo cultured tumors were quantitatively screened for cytokines, chemokines, and growth factors, identifying CCL5 and GM-CSF, molecules associated with skin cancer metastasis, to be markedly decreased. These findings suggest gas plasma treatment to be an interesting future technology for non-melanoma skin cancer topical therapy.

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.

Background: Desmoplastic squamous cell carcinoma (DSCC) is a variant of squamous cell carcinoma (SCC) with aggressive histologic and clinical features. DSCC has a 6 to 10 times higher rate of both local recurrence and metastatic spread compared with well-differentiated SCC. Clinical estimation of tumor margins can grossly underestimate both the depth and the peripheral extent of the tumor. Surgery with intraoperative margin control has been recommended. In many cases, postoperative radiotherapy or prophylactic lymph node dissection may be required. Case Presentation: A 71-year-old man with a biopsy positive for DSCC involving the left postauricular area was treated with nine-stage Mohs micrographic surgery before the tumor margins were negative. Conclusion: There are minimal reports in the literature pertaining to the presentation and treatment of DSCC; therefore, definitive conclusions are difficult. The depth of tumor penetration and peripheral spread of the DSCC presented in this case, however, supports the need for aggressive surgical excision, preferably with intraoperative margin control. To maximize the chance of cure, physicians must be aware of the distinct clinical and histologic features of DSCC and the aggressive treatment required.

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.

Background Non-melanoma skin cancer (NMSC), including basal and squamous cell carcinoma (BCC and SCC), represents the most common malignancy. Objective To provide guidance to Canadian health care practitioners regarding primary prevention of NMSC. Methods Structured literature searches were conducted, using search terms including prevention, sunscreen, and sun prevention factor. All recommendations concern guidance that physicians should regularly discuss with their patients to help establish photoprotection habits. The GRADE system was used to assign strength to each recommendation. Results Ultraviolet exposure is the major modifiable risk factor for NMSC. Aspects of photoprotection, including effective sunscreen use and avoidance of both the midday sun and artificial tanning, are discussed. Several widespread misunderstandings that undermine responsible public health measures related to sun safety are addressed. Conclusions Photoprotection represents both an individual priority and a public health imperative. By providing accurate information during routine patient visits, physicians reinforce the need for ongoing skin cancer prevention.

AbstractBackground:Parotid gland tumours are complex neoplasms with a broad histological range. The parotid gland is also a common site of face and scalp skin cancer metastases.Method:Parotidectomies performed by ENT department in the Gold Coast health district from 2006 to 2013.Results:A total of 158 specimens were examined. Of these, 53.80 per cent were benign and 46.20 per cent were malignant. Pleomorphic adenoma was the most common tumour (29.11 per cent), followed by cutaneous squamous cell carcinoma (23.42 per cent) and Warthin's tumour (12.03 per cent).Conclusion:Metastatic squamous cell carcinoma accounted for a large proportion of parotid masses in our case series, reflecting the high prevalence of non-melanoma skin cancer in Australia. Primary parotid neoplasms had similar incidence rates to other studies.
