PURPOSE: Immunosuppressive therapy plays a major role in the development of post-transplant cancer. In this nested case-control study of kidney transplant recipients (KTRs), we investigated whether the incidence of post-transplant cancer is associated with the level of tacrolimus exposure over time. METHODS: We screened the Rabin Medical Center database for adults who received kidney transplants between 2001 and 2014 and developed post-transplant cancer (excluding basal and squamous cell skin cancers)...

BackgroundSkin cancer is the most common malignancy occurring after organ transplantation. Although previous research has reported an increased risk of skin cancer in solid organ transplant recipients (OTR), no study has estimated the post-transplant population-based incidence in the US. The objective of this study is to determine the incidence and evaluate the predictors of post-transplant skin cancer, including squamous cell carcinoma (SCC), melanoma (MM), and Merkel cell carcinoma (MCC) in a cohort of US OTR receiving a primary transplant in 2003 or 2008...

AbstractBackgroundThe mortality rate for melanoma continues to rise and the greatest improvement in melanoma survival is attributable to early detection with skin cancer screening exams. However, physicians feel that limited training in the examination of skin and limited clinical time both serve as barriers to adequately assess high-risk lesions.ObjectiveTo test the use of The Integrated Skin Exam film as an instructional tool to teach the examination of skin in a live classroom setting, outside of the purview of the original formal study...

Full-body skin exams (FBSE) play an integral role inearly detection and treatment of skin cancer. Promptdetection of melanoma is especially importantas survival outcomes decrease significantly withpresentation of advanced disease. Given thatmelanoma may grow in areas of skin with little to nosun exposure, genital melanomas are a recognizedentity in cutaneous oncology.

Skin cancer screening has undoubted potential to reduce cancer-specific morbidity and mortality. Total-body exams remain the prevailing concept of skin cancer screening even if effectiveness and value of this method are controversial. Meanwhile, store and forward teledermatology was shown to be a reliable instrument for several diagnostic purposes mostly in specialized dermatology settings. The objective of this study was to evaluate most convenient mobile teledermatology interventions as instruments for skin cancer screening in a representative population...

Basal cell carcinoma (BCC) is the most common non-melanoma skin cancer. Conventional diagnosis of BCC requires invasive biopsies. Recently, a high-definition optical coherence tomography (HD-OCT) technique has been developed, which provides a non-invasive in vivo imaging method of skin. Good agreements of BCC features between HD-OCT images and histopathological architecture have been found. Therefore it is possible to automatically detect BCC using HD-OCT. This paper presents a novel BCC detection method that consists of four steps: graph based skin surface segmentation, surface flattening, deep feature extraction and the BCC classification...

Importance: The lack of prospective randomized clinical trials demonstrating that full-body skin examination (FBSE) reduces melanoma morbidity or mortality has prompted an "I" rating from the United States Preventive Services Task Force for population-based skin cancer screening. More data on these screening programs are needed. Objectives: To describe a skin cancer screening quality initiative in a large health care system and to determine if the intervention was associated with screening of a demographically higher-risk population than previous screening programs and if melanoma incidence and thickness differed in screened vs unscreened patients...

BACKGROUND: Skin cancer screening interventions often relay on the involvement of general practitioners (GPs). Many interventions up to now have been directed to training approaches focusing on the clinical features of skin malignancies to increase GPs skill in skin cancer recognition. METHODS: Based on the available current knowledge about skin cancer epidemiology and risk factors, we built up a 5-point checklist to help GPs in triaging patients to be referred to a dermatologist...

Melanoma is the most aggressive type of skin cancer and efforts to improve the diagnosis of this neoplasia are largely based on the use of cell lines. Metabolomics is currently undergoing great advancements towards its use to screening for disease biomarkers. Although NMR metabolomics includes both 1D and 2D methodologies, there is a lack of data in the literature regarding heteronuclear 2D NMR assignments of the metabolome from eukaryotic cell lines. The present study applied NMR-based metabolomics strategies to characterize aqueous and lipid extracts from murine melanocytes and melanoma cell lines with distinct tumorigenic potential, successfully obtaining fingerprints of the metabolites from the extracts of the cell lines by means of 2D NMR HSQC correlation maps...

Skin cancer, the most common human malignancy, is primarily diagnosed visually, beginning with an initial clinical screening and followed potentially by dermoscopic analysis, a biopsy and histopathological examination. Automated classification of skin lesions using images is a challenging task owing to the fine-grained variability in the appearance of skin lesions. Deep convolutional neural networks (CNNs) show potential for general and highly variable tasks across many fine-grained object categories. Here we demonstrate classification of skin lesions using a single CNN, trained end-to-end from images directly, using only pixels and disease labels as inputs...

PURPOSE: The incidence of non-melanoma skin cancer (NMSC) has been increasing over the past 30 years. There are different treatment options and surgical excision is the most frequent treatment due to its low rates of recurrence. Radiotherapy is an effective alternative of surgery, and brachytherapy (BT) might be a better therapeutic option due to high radiation dose concentration to the tumor with rapid dose fall-off resulting in normal tissues sparing. The aim of this review was to evaluate the local control, toxicity, and cosmetic outcomes in NMSC treated with high-dose-rate BT (HDR-BT)...
