Nonmelanoma Skin Cancers

Background: Development of nonmelanoma skin cancers (NMSCs) has been associated with certain risk factors, but studies of the association between ABO blood group and NMSCs have been rare and inconclusive. The aim of this study was to assess the association of the previously known risk factors and blood group as a new potential risk factor in NMSCs. Methods: The study included 401 patients, 202 men, and 199 women, which included 367 diagnosed cases of basal cell carcinoma and 148 diagnosed cases of squamous cell carcinoma. The control group consisted of 438 subjects, 198 men, and 240 women. A standardized questionnaire adapted for this targeted study was used. The relation between the dependent variable (NMSCs) and independent variables was investigated by logistic regression. Results: Compared to the non AB blood group, the risk of developing NMSCs was significantly higher in the AB blood group (MOR = 2.28; 95% CI = 1.41–3.69). We established a logistic model that could best describe the probability of NMSCs development. Conclusion: Study results are expected to instigate basic research into the role of A and B antigens in normal skin epithelium, NMSCs etiopathogenesis, possible effect on metastatic potential and disease prognosis, potential tumor immunotherapy, and targeted detection and prevention in subjects at an increased risk of NMSCs development.

Neoplastische Hautläsionen sind multifokal auftretende, diffuse Hautinfiltrationen, die besonders in der Differentialdiagnose ulzerativer, nodulärer oder verkrustender Hautläsionen von Bedeutung sind. Nicht-melanozytäre Hautkrebsformen (nonmelanoma skin cancers, NMSC) wie das Basalzellkarzinom (basal cell carcinoma, BCC), das Plattenepithelkarzinom (squamous cell carcinoma, SCC) und die aktinische Keratose (AK) sind die häufigsten malignen Tumoren beim Menschen. BCC wachsen langsam und bilden meist keine Metastasen, wohingegen SCC ein stärker infiltrierendes, destruierendes Wachstum zeigen und Metastasen bilden. AK sind Vorstufen des kutanen SCC. Bei der klassischen NMSC-Therapie kommt die photodynamische Therapie in Verbindung mit Chemotherapeutika zur Anwendung. Das zunehmende Verständnis der Pathomechanismen, die bei der Tumorentstehung, -progression und -differenzierung eine Rolle spielen, stützt die Anwendung zielgerichteter Chemotherapien zur Verringerung der Zytotoxizität klassischer Therapien. Die vorliegende Übersichtsarbeit beschreibt den aktuellen Wissensstand über NMSC, einschließlich der Risikofaktoren, Onkogene und Karzinogenese von Hautkrebs und erörtert die herkömmliche Behandlung im Vergleich zu neuartigen therapeutischen Optionen.

Micrographic Surgery

Randomized studies to assess the efficacy of Mohs micrographic surgery in basal cell and squamous cell carcinomas are limited by methodological and ethical issues and a lack of prospective cohorts. This study presents the “real-life” results of a nationwide 7-years cohort on basal cell carcinoma and squamous cell carcinoma treated with Mohs micrographic surgery. A prospective cohort was conducted in 22 Spanish centres (from July 2013 to February 2020) and a multivariate analysis, including characteristics of patients, tumours, surgeries and follow-up, was performed. A total of 4,402 patients followed up for 12,111 patient-years for basal cell carcinoma, and 371 patients with 915 patient-years of follow-up for squamous cell carcinoma were recruited. Risk factors for recurrence included age, non-primary tumours and more stages or unfinished surgeries for both tumours, and immunosuppression for squamous cell carcinoma. Incidence rates of recurrence were 1.3 per 100 person-years for basal cell carcinoma (95% confidence interval 1.1–1.5) and 4.5 for squamous cell carcinoma (95% confidence interval 3.3–6.1), being constant over time (0–5 years). In conclusion, follow-up strategies should be equally intense for at least the first 5 years, with special attention paid to squamous cell carcinoma (especially in immunosuppressed patients), elderly patients, non-primary tumours, and those procedures requiring more stages, or unfinished surgeries.

Background: The skin is a heterogeneous organ, capable of producing various types of skin tumors. The incidence of skin cancers, including melanoma and non-melanoma has been reported to have risen in many parts of the world. In Asian and African countries, individuals with pigmented races have a much lower incidence of skin cancers despite sunny hot weather. This study is aimed to analyze age, sex and site wise of distribution of skin cancers. Materials and Methods: The study included a total of 60 patients with histopathologically proven skin cancers from January 2015 to December 2018 in the department of pathology, DI skin health and referral centre, Kathmandu, Nepal. Results: A total of 60 cases of histopathologically proven skin cancer constituted 3.69% of total skin biopsies. Patient age ranged from 15 to 88 years with mean age being 61 years. The majority of the patients were in the age group of 61-70 yrs. The male to female ratio is 1:1.3. Basal cell carcinoma was the most common skin cancer constituting 43.4%, followed by squamous cell carcinoma (28.3%). The most common site of skin cancer is head & neck (73.3%), followed by lower extremities (8.3%). Other skin cancers were Bowen’s disease, melanoma, verrucous carcinoma, keratoacanthoma, trichilemmal carcinoma, extramammary Paget’s disease, Non-Hodgkin lymphoma and metastatic tumor. Conclusions: The most common type of skin cancer is basal cell carcinoma, followed by squamous cell carcinoma and head & neck being the commonest site.

Ubiquitin and ubiquitin-related proteins posttranslationally modify substrates, and thereby alter the functions of their targets. The ubiquitination process is involved in various physiological responses, and dysregulation of components of the ubiquitin system has been linked to many diseases including skin cancer. The ubiquitin pathways activated among skin cancers are highly diverse and may reflect the various characteristics of the cancer type. Basal cell carcinoma and squamous cell carcinoma, the most common types of human skin cancer, are instances where the involvement of the deubiquitination enzyme CYLD has been recently highlighted. In basal cell carcinoma, the tumor suppressor protein CYLD is repressed at the transcriptional levels through hedgehog signaling pathway. Downregulation of CYLD in basal cell carcinoma was also shown to interfere with TrkC expression and signaling, thereby promoting cancer progression. By contrast, the level of CYLD is unchanged in squamous cell carcinoma, instead, catalytic inactivation of CYLD in the skin has been linked to the development of squamous cell carcinoma. This paper will focus on the current knowledge that links CYLD to nonmelanoma skin cancers and will explore recent insights regarding CYLD regulation of NF-κB and hedgehog signaling during the development and progression of these types of human tumors.

AbstractThe nose is highly vulnerable to skin cancers due to the unavoidable sun exposure. The most common localization of skin cancers on the face is nose. Although the nose appears to be a single structure, it comprises many aesthetic units with different histological and anatomical properties. Our aim was to determine the relationship between the prevalence of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), histologically and anatomically distinct nasal subunits. The study included patients who underwent excision and repair due to BCC or SCC of the nose. The lesions were classified according to their location in the following topographic subunits: tip, alar lobule, dorsum, sidewall, and medial canthal region. Patients were analyzed according to age, sex, topographic subunit, tumor type, and repair technique. There was no statistically significant difference in tumor location according to etiology (p > 0.05). The alar subunit was the most common location of BCC, while the dorsum was the most common location for SCC. There is no statistical relationship between the two most common skin cancers, BCC and SCC, and the aesthetic subunits of the nose. The only factor associated with the reconstruction method used was the subunit in which the tumor was located.
