Skin cancer is the most common of human cancers and outnumbers all other types of cancer combined in the USA by over threefold. The majority of non-melanoma skin cancers are easily treated with surgery or locally destructive techniques performed under local anesthesia in the cost-effective outpatient setting. However, there is a subset of "high-risk" cases that prove challenging in terms of morbidity, mortality, adjuvant treatment required, as well as overall cost to the health care system. In our opinion, the term "high risk" when applied to skin cancer can mean one of three things: a high-risk tumor with aggressive histologic and/or clinical features with an elevated risk for local recurrence or regional/distant metastasis, a high-risk patient with the ongoing development of multiple skin cancers, and a high-risk patient based on immunosuppression...

Non-melanoma skin cancers (NMSC) are a growing problem given that solar UVB radiation exposure is increasing most likely due to depletion of the atmospheric ozone layer and lack of adequate sun protection. Better preventive methods are urgently required to reduce UV-caused photodamage and NMSC incidence. Earlier, we have reported that silibinin treatment activates p53 and reduces photodamage and NMSC, both in vitro and in vivo; but whether silibinin exerts its protective effects primarily through p53 remain unknown...

Inhibition of tumor necrosis factor (TNF) activity has profoundly changed the management of several immune-mediated inflammatory diseases with great benefit for patients. The application of TNF inhibitors (TNFi), however, also brings a new concern, malignancy. We performed a systemic review to collect the studies reporting cancer incidences and risks in TNFi users regardless of indications. TNFi were most frequently used in treating patients with rheumatoid arthritis (RA) and inflammatory bowel diseases (IBD)...

Nonmelanoma skin cancer (NMSC) is the most common cancer worldwide and the incidence continues to rise, in part due to increasing numbers in high-risk groups such as organ transplant recipients and those taking photosensitizing medications. The most significant risk factor for NMSC is ultraviolet radiation (UVR) from sunlight, specifically UVB, which is the leading cause of DNA damage, photoaging, and malignant transformation in the skin. Activation of apoptosis following UVR exposure allows the elimination of irreversibly damaged cells that may harbor oncogenic mutations...

Purpose Indoor tanning is associated with an increased risk of non-melanoma skin cancers (NMSC), yet little is known about indoor tanning habits of individuals with a history of NMSC. Methods We examined self-reported history of NMSC and tanning bed use among non-Hispanic white respondents in the 2010 National Health Interview Survey (NHIS), a cross-sectional population-based survey designed to be representative of the civilian US population. We computed weighted population estimates and standard errors using the Taylor series linearization method...

Importance: Confocal microscopy has the potential to provide rapid bedside pathologic analysis, but clinical adoption has been limited in part by the need for physician retraining to interpret grayscale images. Digitally stained confocal mosaics (DSCMs) mimic the colors of routine histologic specimens and may increase adaptability of this technology. Objective: To evaluate the accuracy and precision of 3 physicians using DSCMs before and after training to detect basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) in Mohs micrographic surgery fresh-tissue specimens...

It has been reported that patients receiving renal replacement therapy (RRT), including dialysis and kidney transplantation, tend to have an increased risk of cancer; however, studies on the degree of this risk have remained inconclusive. The present meta-analysis was therefore performed to quantify the cancer risk in patients with RRT. Cohort studies assessing overall cancer risk in RRT patients published before May 29, 2015 were included following systematic searches with of PubMed, EMBASE and the reference lists of the studies retrieved...

BACKGROUND: The treatment of cutaneous advanced non-melanoma skin cancers (NMSC) and multiple cutaneous and subcutaneous melanoma metastases (Mm) represents a main therapeutic challenge. Electrochemotherapy (ECT) is an anticancer procedure that facilitates the penetration of cytotoxic drugs into cancer cells by means of the application of electrical pulses. The aim of our study was to evaluate efficacy and tolerability of ECT in the treatment of advanced NMSC and Mm. METHODS: Thirteen patients with a total of 88 cutaneous and subcutaneous tumour lesions were selected (69 Mm in 6 patients and 19 NMSC in 7 patients)...

National level population-based cancer data have never been published from Pakistan in seven decades since independence (1947). Therefore, generation of high-quality regional data becomes highly relevant. Cancer data for the period of 2010-2015 representing the population from all districts of Karachi (14.6 million) are presented herein. After institutional approval (Ref no. IRB-459/DUHS/-14), a Pathology based cancer registry was established at the largest government-run diagnostic and reference center of Karachi...

BACKGROUND: Early diagnosis of non-melanoma skin cancer (NMSC) is potentially possible using optical coherence tomography (OCT) which provides non-invasive, real-time images of skin with micrometre resolution and an imaging depth of up to 2mm. OCT technology for skin imaging has undergone significant developments, improving image quality substantially. The diagnostic accuracy of any method is influenced by continuous technological development making it necessary to regularly re-evaluate methods...

PURPOSE: Brachytherapy (BT), due to rapid dose fall off and minor set-up errors, should be superior to external beam radiotherapy (EBRT) for treatment of lesions in difficult locations like nose and earlobe. Evidences in this field are scarce. We describe computed tomography (CT) based surface mould BT for non-melanoma skin cancers (NMSC), and compare its conformity, dose coverage, and tissue sparing ability to EBRT. MATERIAL AND METHODS: We describe procedure of preparation of surface mould applicator and dosimetry parameters of BT plans, which were implemented in 10 individuals with NMSC of nose and earlobe...

PURPOSE: Non-melanomatous skin cancer (NMSC) is the single most common cancer in the US. Radiation therapy is an excellent treatment alternative to surgery. High-dose-rate (HDR) brachytherapy and external beam radiotherapy (EBRT) are commonly used radiation treatment modalities but little data is published comparing these modalities. We present our institution's experience and outcomes with these therapeutic options. MATERIAL AND METHODS: From June 2005 to March 2013, 61 patients were treated with HDR brachytherapy (n = 9), hypofractionated EBRT (n = 30), or standard fractionation EBRT (n = 22) for NMSC...

BACKGROUND: Organ transplant recipients (OTRs) are more susceptible to various diseases, among them cancers. Nonmelanoma skin cancers (NMSC) represent the most common malignancies in OTRs in Europe. Due to the significantly higher morbidity, aggressive and rapid progression, and poor prognosis of NMSC in the OTR population, these patients require a special oncological approach. Intensive attention should therefore be paid to factors predisposing OTRs to the development of cancer. The aim of this study was to establish the role of genetic factors in the pathogenesis of skin cancer in kidney transplant recipients (KTRs)...

BACKGROUND AND OBJECTIVE: Nonmelanoma skin cancer (NMSC) is the most common form of cancer worldwide. The most effective form of treating this cancer is its surgical removal. As NMSC rarely metastasize, its complete excision is often curative. We investigated the potential of combining Terahertz Pulsed Imaging (TPI) with polarization enhanced reflectance optical imaging for the accurate intraoperative delineation of NMSC. MATERIALS AND METHODS: Fresh thick samples with residual cancer were obtained from surgeries...
