BACKGROUND: Mohs micrographic surgery (MMS) is used to treat certain high-risk non-melanoma skin cancers (NMSC) due to its high cure rate. However, clinical recurrences do occur in a small number of cases. OBJECTIVE: We examined specific clinical characteristics associated with NMSC recurrences following MMS. METHODS: We employed a retrospective chart review of the 1467 cases of NMSC that underwent MMS at UC San Diego from January 1, 2008 through December 31, 2009...

BACKGROUND: Skin cancer is the most common type of cancer. Of the 4 million skin lesions excised annually worldwide, approximately 2 million are considered cancerous. In this study, we aimed to describe a regional experience with skin cancers treated by a single senior surgeon and to provide a treatment algorithm. METHODS: The medical records of 176 patients with head and neck non-melanocytic skin cancer (NMSC) who were treated by a single surgeon at our institution between January 2010 and May 2016 were retrospectively reviewed, and their data (age, sex, pathological type, tumor location/size, treatment modality) were analyzed...

We investigated UV-induced signaling in an ex vivo skin organ culture model using phospho-antibody array. Phosphorylation modulations were analyzed in time-course experiments following exposure to solar-simulated UV and validated by western blot analyses. We found that UV induced P-p38 and its substrates, P-ERK1/2 and P-AKT which were previously shown to be upregulated by UV in cultured keratinocytes and in vivo human skin. This indicates that phospho-antibody array applied to ex vivo skin organ culture is a relevant experimental system to investigate signaling events following perturbations...

BACKGROUND: The pathology observed on initial biopsy specimens for nonmelanoma skin cancer (NMSC), specifically the tumor subtype, weighs heavily into the selection of the treatment modality. Recognizing aggressive features on intraoperative Mohs micrographic surgery (MMS) frozen sections that were not indicated on initial biopsy reports is not uncommon. To date, there is limited data describing this discrepancy. OBJECTIVE: To investigate the frequency and nature of incongruity between the pathology seen in initial biopsies and intraoperative Mohs sections, providing information that will potentially impact skin cancer treatment and biopsy recommendations...

Most cancer forms known to be caused by viruses are increased among the immunosuppressed, but several cancer forms without established viral etiology are also increased, notably non-melanoma skin carcinoma (NMSC). We followed all 13429 solid organ transplantation patients in Sweden for cancer occurrence after transplantation. We requested these tumor specimens and sequenced the first 89 specimens received (62 NMSCs, 27 other cancers). The sequences were analyzed for viruses based on two bioinformatics algorithms (paracel-blast (sensitive for detection of known viruses) and hidden Markov model (HMM; sensitive for distantly related viruses))...

Importance: Protective effects of UV-B radiation against nonmelanoma skin cancer (NMSC) are exerted via signaling mechanisms involving the vitamin D receptor (VDR). Recent studies have examined single-nucleotide polymorphisms (SNPs) in the VDR, resulting in contradictory findings as to whether these polymorphisms increase a person's risk for NMSC. Objective: To examine whether the polymorphisms in the VDR gene are associated with the development of NMSC and the demographic characteristics of the participants...

A significant relationship between arsenic exposure and non-melanoma skin cancer (NMSC) is well known. The toxicity of arsenics which develop NMSC is dependent on their species. Accordingly, total arsenic levels are unreliable for risk assessment of NMSC. However, there are few studies on quantitative exposure assessment of arsenic species in NMSC patients. To validate the contribution of each arsenic species to NMSC, we compared the creatinine-adjusted urinary concentration of arsenic species in NMSC patients and community controls...

Actinic keratosis (AK) is a characteristic skin lesion on skin areas of subjects with mainly phototype I and phototype II, or with specific genetic factors and who are exposed to prolonged ultraviolet radiation. AK may be considered a precursor of in situ squamous cell carcinoma (SCC), a type of non-melanoma skin cancer (NMSC). However, it is still not possible to predict which AK lesions will develop into SCC. Early treatment of AK is therefore recommended. Despite the increasing number of patients with AK developing into SCC, to date, there is still no clear suggestion of therapeutic strategy for AK...

This study investigated the risk of non-melanoma skin cancer (NMSC) in pre-dialysis patients with chronic kidney disease (CKD) and explored associated risk factors. A population-based cohort of 1,515,858 Taiwanese CKD patients was included. The standardized incidence ratio (SIR) for incident NMSC was determined. Compared with the general population, a 1.14-fold risk of NMSC was found in the CKD cohort. NMSC risk was significant in patients with pre-dialysis stage 5 CKD and anaemia (1.48-fold), and in those with uraemic pruritus after long-term antihistamine treatment (1...

BACKGROUND: Voriconazole has previously been associated with increased risk for cutaneous squamous cell carcinoma (SCC) in solid organ transplant recipients. Less is known about the risk in patients after hematopoietic cell transplantation (HCT). OBJECTIVE: We evaluated the effect of voriconazole on the risk for nonmelanoma skin cancer (NMSC), including SCC and basal cell carcionoma, among those who have undergone allogeneic and autologous HCT. METHODS: In all, 1220 individuals who had undergone allogeneic HCT and 1418 who had undergone autologous HCT were included in a retrospective cohort study...

BACKGROUND: Skin biopsies only provide point-in-time data making longitudinal studies difficult. Using Dynamic optical coherence tomography (D-OCT) in vivo, non-invasive imaging of the microvasculature becomes possible. The current OCT literature is almost exclusively based on qualitative information but quantitative data may offer additional advantages, for example, by reducing observer variation. The objective of this study was to evaluate the in vivo superficial distribution of blood vessels, defined as the surface-to-first-vessel distance, in actinic keratosis, basal cell carcinoma, squamous cell carcinoma and normal skin...

INTRODUCTION: Hypoxia Inducible Factor-1 (HIF-1) is a mediator enabling cell adaptation to hypoxia. It plays its role mainly through transcription of many target genes including Glucose Transporter-1 (GLUT-1) gene. AIM: The present work aimed at evaluating the pattern and distribution of HIF-1α and GLUT-1 in each case and control. MATERIALS AND METHODS: A case-control and retrospective study was conducted on archival blocks diagnosed from pathology department as, Basal Cell Carcinoma (BCC, 20 cases), cutaneous Squamous Cell Carcinoma (SCC, 20 cases) and 20 normal site-matched skin biopsies from age and gender-matched healthy subjects as a control...

Nonmelanoma skin cancer (NMSC) comprises mainly basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC). The association between alcohol intake and NMSC has been inconclusive; therefore the objective of this study is to quantify the relationship between alcohol intake and NMSC using meta-analyses. A systematic literature search of PubMed and Embase was performed on 30 October 2016. Eligible articles were case-control or cohort studies that examined alcohol intake and risk of BCC or cSCC and reported relative risks (RRs) with 95% confidence intervals (CIs)...

BACKGROUND: Jeju Island is geographically and socioeconomically distinct from the mainland of South Korea. Thus, the presentation and management of non-melanocytic skin cancers (NMSC) of the head and neck may differ from those in other regions of the country. We compared the clinical characteristics and treatment modalities of NMSC on Jeju Island with the findings of similar regional studies. METHODS: Patient data, including age, sex, diagnosis, tumor site, treatment, and recurrence, were obtained from the medical and pathology records of patients diagnosed with NMSC between January 2010 and June 2015...

PURPOSE: The use of radiation therapy (RT) for non-melanoma skin cancer (NMSC) has been changing throughout the last century. Over the last decades, the use of radiotherapy has surged with the development of new techniques, applicators, and devices. In recent years, electronic brachytherapy (eBT) devices that use small x-ray sources have been introduced as alternative to radionuclide dependence. Nowadays, several devices have been incorporated, with a few series reported, and with a short follow-up, due to the recent introduction of these systems...

Biologic therapies are highly effective in psoriasis, but have profound effects on innate and adaptive immune pathways that may negatively impact on cancer immunosurveillance mechanisms. To investigate the risk of cancer in psoriasis patients treated with biologic therapy we searched Medline, Embase, and the Cochrane Library (up to August 2016) for randomized control trials, prospective cohort studies and systematic reviews that reported cancer incidence in people exposed to biologic therapy for psoriasis compared to a control population...

Locoregionally advanced nonmelanoma skin cancer (NMSC) has an aggressive clinical course characterized by high rates of treatment failure and poor survival compared with localized skin cancers. Our goal was to investigate multimodal therapy for lymph-node-positive NMSC. Data from patients with lymph-node-positive NMSC who underwent surgery and adjuvant therapy at a single tertiary center from 2002 to 2012 were retrospectively reviewed. Median follow-up was 1.8 years (range: 0.5 to 8.5). Overall survival (OS) and progression-free survival (PFS) were calculated using the Kaplan-Meier method...

Non‑melanoma skin cancer (NMSC) is the most common form of cancer worldwide, comprising 95% of all cutaneous malignancies and approximately 40% of all cancers. In spite of intensive efforts aimed towards awareness campaigns and sun‑protective measures, epidemiological data indicate an increase in the incidence of NMSC. This category of skin cancers has many common environmental triggers. Arising primarily on sun‑exposed skin, it has been shown that ultraviolet radiation is, in the majority of cases, the main trigger involved in the pathogenesis of NMSC...
