BACKGROUND: To evaluate cancer incidence among licenced commercial pilots in association with cosmic radiation. METHODS: Cohort study where ionizing radiation dose of cosmic radiation was estimated from airline data and software program and cancer incidence was obtained by record linkage with nation-wide cancer registry. All licenced commercial male airline pilots were followed from 1955 to 2015, ever or never employed at airline with international routes. Standardized incidence ratios were calculated and relative risk by Poisson regression, to examine exposure-response relation...

Nonmelanoma skin cancer is the most common cancer in humans, comprising mainly basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). BCC proliferation is highly dependent on the Hedgehog signaling pathway. We aimed to investigate a panel of anticancer drugs with known activity against skin cancer for their therapeutic potential in localized, enhanced topical treatment of SCC and BCC. Cytotoxicity profiles for vismodegib, 5-fluorouracil (5-FU), methotrexate (MTX), cisplatin, bleomycin, and vorinostat were established in terms of half maximal inhibitory concentration values in a panel of immortalized keratinocytes (HaCaT), BCC (UWBCC1 and BCC77015), and SCC (A431 and SCC25) cell lines...

PURPOSE: Endometriosis has been associated with an increased risk of skin melanoma. However, associations with other skin cancer types and how they compare with melanoma are unclear. Our objective was to prospectively investigate the relationships between endometriosis and risk of non-melanoma and melanoma skin cancers. METHODS: E3N is a prospective cohort of 98,995 French women aged 40-65 years in 1990. Data on surgically confirmed endometriosis and skin cancer diagnoses were collected every 2-3 years through self-report, with skin cancer cases confirmed through pathology reports...

INTRODUCTION: Bendamustine, typically in combination with rituximab, is an effective treatment for chronic lymphocytic leukemia (CLL) and B-cell non-Hodgkin lymphoma. Despite its acceptable short-term toxicity profile, long-term toxicities are less well established. This study investigated the long-term adverse effects of bendamustine and responses to subsequent treatments. PATIENTS AND METHODS: Charts of 194 patients were retrospectively reviewed; 54% had received prior treatment (76% attained complete response [CR] or partial response [PR])...

BACKGROUND: Vismodegib is a first-in-class agent targeting the hedgehog signaling pathway for treatment of patients with locally advanced basal cell carcinoma (BCC) and metastatic BCC. There have been concerns about the development of squamous cell carcinoma (SCC) in patients treated with this drug. OBJECTIVE: We sought to determine whether treatment with vismodegib is associated with an increase in the risk of cutaneous SCC. METHODS: In this retrospective cohort study, patients treated with vismodegib as part of phase I and II clinical studies were compared with participants from the University of California, San Francisco, Nonmelanoma Skin Cancer Cohort who received standard therapy for primary BCC...

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...

OBJECTIVES: Arc welding produces the full spectrum of ultraviolet radiation and may be a contributory cause of skin cancer; however, there has been little research into this occupational hazard. The aim of this study is to explore if metal arc welding increases the risk of malignant melanoma and/or basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) on skin areas which may possibly be exposed (neck, head, and upper extremities). METHOD: A Danish national company-based historic cohort of 4333 male metal arc welders was followed from 1987 through 2012 to identify the risk of skin cancer...

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...

The phasor approach to fluorescence lifetime imaging microscopy (FLIM) is used to identify different types of tissues from hematoxylin and eosin (H&E) stained basal cell carcinoma (BCC) sections. The results suggest that working directly on the phasor space with the clustering assignment achieves immunofluorescence like simultaneous five or six-color imaging by using multiplexed fluorescence lifetimes of H&E. The phase approach is of particular effectiveness for enhanced visualization of the abnormal morphology of a suspected nidus...

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)...

Multiple malignancies are an increasing combination in the recent years in cancer patients, due to prolonged survival rate and to the advances in diagnostic techniques and therapeutic management. We present the case of a patient diagnosed with prostate cancer and metachronous in one year with basal cell carcinoma of the skin and small lung cell carcinoma with lymph nodes and pararectal metastasis. To our best knowledge, this is the only case presented in the medical literature with these three different types of primary malignancy...

BACKGROUND: Free-flap surgery and skin grafting can be used to reconstruct large facial defects that may result after skin cancer removal by Mohs micrographic surgery (MMS). However, these two methods may produce low postsurgical patient satisfaction with aesthetics, and free-flap surgery may produce an undue burden for the majority of skin cancer patients, who are of advanced age. Hence, the authors examined outcomes of large facial defect reconstruction using multiple flaps. METHODS: Among patients undergoing MMS for skin cancer at Pusan National University Hospital between January 2013 and December 2015, we evaluated 7 patients (2 males, 5 females; average age, 73...

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...

Basal cell carcinoma (BCC) also known as basalioma or basal cell cancer, is the most common skin cancer. BCC has a very low metastatic risk. This tumor can cause significant disfigurement by invading surrounding tissues. It occurs mainly in fair-skinned patients with a family history of this cancer. Sunlight is a factor in about two-thirds of these cancers. Standard surgical excision is the treatment of choice. Mohs micrographic surgery is an outpatient or inpatient procedure in which the tumor is surgically excised and then immediately examined under a microscope...

Photodynamic therapy (PDT) is an effective treatment for actinic keratoses and early skin cancers, and the only office procedure to control field cancerization. Procedure-associated pain limits widespread PDT use and by early termination of treatment can decrease overall therapeutic efficacy. Here we review and assess reported interventions on PDT-associated pain, in order to identify the most promising methods to manage treatment-associated pain and identify focus for future studies. Literature search was performed using MEDLINE, EMBASE, and the Cochrane Library by two independent reviewers to select publications that assessed and compared pain quantitatively during PDT treatment for actinic keratoses, basal cell carcinomas, and/or in situ squamous cell carcinomas...

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...
