What's new in skin cancer? An analysis of guidelines and systematic reviews published in 2008-2009
Department of Dermatology, Norfolk and Norwich University Hospitals NHS Foundation Trust, Norwich, UK.Clinical and Experimental Dermatology (Impact Factor: 1.09). 07/2011; 36(5):453-8. DOI: 10.1111/j.1365-2230.2011.04087.x
This review summarizes clinically important findings from 17 systematic reviews and 2 guidelines on skin cancer indexed between April 2008 and April 2009. Melanoma primary-prevention measures, such as education, are more likely to be successful in younger children than adolescents, and general population screening for melanoma by whole-body examination is not currently supported by the evidence. A large systematic review of melanoma and pregnancy concluded that pregnancy does not affect prognosis. Two systematic reviews imply that sunburn later in life also increases the risk of melanoma, and that it is just as important as sunburn early in life. Three systematic reviews discussed the role of positron emission tomography and sentinel lymph-node biopsy for melanoma staging, but produced conflicting results. Superior diagnostic accuracy of dermatoscopy over naked-eye examination for melanoma was found in one review, while a second implied nonsignificantly higher sensitivity of computer-based diagnostic methods over dermatoscopy for melanoma but with reduced specificity. There were no identified randomized controlled trials of treatments for unresectable recurrent melanoma, and a review of immunotherapy with vaccines for melanoma failed to prove improved overall and disease-free survival. Guidelines for the management of basal cell carcinoma call for risk stratification, based on numerous factors including tumour size, site and histological subtype. Squamous cell carcinoma of the ear has been shown to spread to regional lymph nodes more commonly than to other sites, and may be predicted by depth of invasion, tumour size, cellular differentiation and completeness of excision.

ABSTRACT: Nonmelanoma skin cancer (NMSC) represents the most common form of cancer in Caucasians, with continuing increase in incidence worldwide. Basal cell carcinoma (BCC) accounts for 75% of cases of NMSC, and squamous cell carcinoma (SCC) accounts for the remaining majority of NMSC cases. Whilst metastasis from BCC is extremely rare, metastasis from high-risk SCC may be fatal. In this article, we review the aetiology, diagnosis and management of NMSC.Journal of Cutaneous and Aesthetic Surgery 01/2012; 5(1):3-10. DOI:10.4103/0974-2077.94323

ABSTRACT: Many research studies have been published on atopic eczema and these are often summarised in systematic reviews (SRs). Identifying SRs can be time-consuming for health professionals, and researchers. In order to facilitate the identification of important research, we have compiled an on-line resource that includes all relevant eczema reviews published since 2000. SRs were searched for in MEDLINE (Ovid), EMBASE (Ovid), PubMed, the Cochrane Database of Systematic Reviews, DARE and NHS Evidence. Selected SRs were assessed against the pre-defined eligibility criteria and relevant articles were grouped by treatment category for the included interventions. All identified systematic reviews are included in the Global Resource of EczemA Trials (GREAT) database (www.greatdatabase.org.uk) and key clinical messages are summarised here. A total of 128 SRs reviews were identified, including three clinical guidelines. Of these, 46 (36%) were found in the Cochrane Library. No single database contained all of the SRs found. The number of SRs published per year has increased substantially over the last thirteen years, and reviews were published in a variety of clinical journals. Of the 128 SRs, 1 (1%) was on mechanism, 37 (29%) were on epidemiology, 40 (31%) were on eczema prevention, 29 (23%) were on topical treatments, 31 (24%) were on systemic treatments, and 24 (19%) were on other treatments. All SRs included searches of MEDLINE in their search methods. One hundred six SRs (83%) searched more than one electronic database. There were no language restrictions reported in the search methods of 52 of the SRs (41%). This mapping of atopic eczema reviews is a valuable resource. It will help healthcare practitioners, guideline writers, information specialists, and researchers to quickly identify relevant up-to-date evidence in the field for improving patient care.PLoS ONE 03/2013; 8(3):e58484.

ABSTRACT: Exposure to ultraviolet radiation and a history of sunburn in childhood contribute to risk of skin cancer in adolescence and in adulthood, but many adolescents continue to seek a tan, either from the sun or from tanning beds (i.e., intentional tanning). To understand tanning behavior among adolescents, we conducted a systematic review of the literature to identify correlates of intentional tanning in the United States. We included articles on original research published in English between January 1, 2001, and October 31, 2011, that used self-reported data on intentional tanning by U.S. adolescents aged 8 to 18 years and examined potential correlates of tanning behaviors. Thirteen articles met our criteria; all used cross-sectional survey data and quantitative methods to assess correlates of intentional tanning. Results indicate that multiple factors influence tanning among adolescents. Individual factors that correlated with intentional tanning include demographic factors (female sex, older age), attitudes (preferring tanned skin), and behaviors (participating in other risky or appearance-focused behaviors such as dieting). Social factors correlated with intentional tanning include parental influence (having a parent who tans or permits tanning) and peer influence (having friends who tan). Only four studies examined broad contextual factors such as indoor tanning laws and geographic characteristics; they found that proximity to tanning facilities and geographic characteristics (living in the Midwest or South, living in a low ultraviolet area, and attending a rural high school) are associated with intentional tanning. These findings inform future public health research and intervention efforts to reduce intentional tanning.Journal of Adolescent Health 05/2013; 52(5 Suppl):S52-9.
