BackgroundClinical and histopathologic assessment of pigmented skin lesions remains challenging even for experts. Differentiated and accurate noninvasive diagnostic modalities are highly desirable.ObjectiveWe sought to provide clinicians with such a tool.MethodsA 2-gene classification method based on LINC00518 and preferentially expressed antigen in melanoma (PRAME) gene expression was evaluated and validated in 555 pigmented lesions (157 training and 398 validation samples) obtained noninvasively via adhesive patch biopsy. Results were compared with standard histopathologic assessment in lesions with a consensus diagnosis among 3 experienced dermatopathologists.ResultsIn 398 validation samples (87 melanomas and 311 nonmelanomas), LINC00518 and/or PRAME detection appropriately differentiated melanoma from nonmelanoma samples with a sensitivity of 91% and a specificity of 69%. We established LINC00518 and PRAME in both adhesive patch melanoma samples and underlying formalin fixed paraffin embedded (FFPE) samples of surgically excised primary melanomas and in melanoma lymph node metastases.LimitationsThis technology cannot be used on mucous membranes, palms of hands, and soles of feet.ConclusionsThis noninvasive 2-gene pigmented lesion assay classifies pigmented lesions into melanoma and nonmelanoma groups and may serve as a tool to help with diagnostic challenges that may be inherently linked to the visual image and pattern recognition approach.

OverviewIn 2016, an estimated 76,380 patients will be diagnosed with and approximately 10,130 patients will die of melanoma in the United States.1 However, these figures for new cases may represent a substantial underestimate, as many superficial and in situ melanomas treated in the outpatient setting are not reported. The incidence of melanoma continues to increase dramatically, at an overall rate of 33% for men and 23% women from 2002 to 2006.2 Melanoma is increasing in men more rapidly than any other malignancy, and in women more rapidly than any other malignancy except lung cancer. AbstractThis selection from the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Melanoma focuses on adjuvant therapy and treatment of in-transit disease, because substantial changes were made to the recommendations for the 2016 update. Depending on the stage of the disease, options for adjuvant therapy now include biochemotherapy and highdose ipilimumab. Treatment options for in-transit disease now include intralesional injection with talimogene laherparepvec (T-VEC), a new immunotherapy. These additions prompted reassessment of the data supporting older recommended treatment options for adjuvant therapy and in-transit disease, resulting in extensive revisions to the supporting discussion sections.

Category 2A: Based upon lower-level evidence, there is uniform NCCN consensus that the intervention is appropriate. Category 2B: Based upon lower-level evidence, there is NCCN consensus that the intervention is appropriate. Category 3: Based upon any level of evidence, there is major NCCN disagreement that the intervention is appropriate.All recommendations are category 2A unless otherwise noted.Clinical trials: NCCN believes that the best management for any cancer patient is in a clinical trial.

Melanoma is usually apparent on the skin and readily detected by trained medical providers using a routine total body skin examination, yet this malignancy is responsible for the majority of skin cancer-related deaths. Currently, there is no national consensus on skin cancer screening in the USA, but dermatologists and primary care providers are routinely confronted with making the decision about when to recommend total body skin examinations and at what interval. The objectives of this paper are: to propose rational, risk-based, data-driven guidelines commensurate with the US Preventive Services Task Force screening guidelines for other disorders; to compare our proposed guidelines to recommendations made by other national and international organizations; and to review the US Preventive Services Task Force's 2016 Draft Recommendation Statement on skin cancer screening.
