Screening for cutaneous melanoma.
ABSTRACT Current data do not support widespread population-based screening for melanoma. While the incidence of melanoma is high, the overall mortality is low, and thus any potential benefit of screening the general population is hard to demonstrate. No randomized controlled trial showing reduction in mortality has ever been completed and, given the expense and time necessary for such a trial, probably will never be completed. The idea of skin screening remains appealing for this common, visible malignancy which is eminently treatable when detected early. Efforts should be focused on populations at particularly high risk of developing melanoma and on those at high risk of death from melanoma once diagnosed. Persons in kindreds of familial melanoma, and persons who have atypical mole syndrome, those who have a prior diagnosis of melanoma, or those who have diagnosed atypical nevi are all reasonable candidates for routine screening, based on lower-level evidence in the absence of randomized clinical trials targeting these groups. Programs targeting persons of low socioeconomic status and targeting white men over the age of 50 could address groups known to beat especially high risk of melanoma mortality.

ABSTRACT: 2-Deoxy-2-[F-18]fluoro-D-glucose (FDG)-positron emission tomography (PET)/computed tomography (CT) is widely available as a powerful imaging modality, combining the ability to detect active metabolic processes and their morphologic features in a single exam. The role of FDG-PET is proven in a variety of cancers, including melanoma, but the estimates of sensitivity and specificity are based in the majority of the published studies on dedicated PET, not PET/CT. Therefore, we were prompted to review our experience with FDG-PET/CT in the management of melanoma. This is a retrospective study on 106 patients with melanoma (20-87 years old; average: 56.8 +/- 15.9), who had whole-body FDG-PET/CT at our institution from January 2003 to June 2005. Thirty-eight patients (35.9%) were women and 68 patients (64.1%) were men. Reinterpretation of the imaging studies for accuracy and data analysis from medical records were performed. All patients had the study for disease restaging. The primary tumor depth (Breslow's thickness) at initial diagnosis was available for 76 patients (71.7%) and ranged from 0.4 to 25 mm (average: 3.56 mm). The anatomic level of invasion in the skin (Clark's level) was determined for 70 patients (66%): 3, level II; 13, level III; 43, level IV; 11, level V. The administered dose of (18)F FDG ranged from 9.8 to 21.6 mCi (average: 15.4 +/- 1.8 mCi). FDG-PET/CT had a sensitivity of 89.3% [95% confidence interval (CI): 78.5-95] and a specificity of 88% (95% CI: 76.2-94.4) for melanoma detection. This study confirms the good results of FDG-PET/CT for residual/recurrent melanoma detection, as well as for distant metastases localization. PET/CT should be an integral part in evaluation of patients with high-risk melanoma, prior to selection of the most appropriate therapy.Molecular Imaging & Biology 01/2007; 9(1):50-7. · 3.10 Impact Factor
Article: Management of Melanoma Families.[show abstract] [hide abstract]
ABSTRACT: In this review we have aimed to focus on the clinical management of familial melanoma patients and their relatives. Along this line three major topics will be discussed: (1) management/screening of familial melanoma families: what is advised and what is the evidence thereof; (2) variability of families worldwide with regard to clinical phenotype, including cancer spectrum and likelihood of finding germline mutations and (3) background information for clinicians on the molecular biology of familial melanoma and recent developments in this field.Cancers. 01/2010; 2(2):549-566.

ABSTRACT: The biopsy lies at the heart of the management of the suspected melanocytic neoplasm. Dermatologists are the ideal physicians to examine patients with suspect melanocytic lesions and an understanding of when and how to perform a biopsy is vital. Various algorithms have been formulated to allow for facilitation of the clinical examination, including the ABCDE rule, the Glasgow 7-point checklist, and the "ugly duckling" sign. Along with this, dermoscopy can increase the sensitivity of diagnosis. Proper training regarding dermatoscopy is essential, especially with algorithms such as the Menzies method, the 7-point checklist, and pattern analysis. Digital photography and digital dermatoscopy allows for surveillance of suspect nevi or patients with multiple nevi. For neoplasms suspected of being melanoma, an excision for diagnosis with 1- to 3-mm borders is ideal, although a shave, punch, or other incisional biopsy can be performed in special circumstances. Finally, research has allowed for promising technologies including gene profiling of tape-stripped samples along with automated software analysis of digital dermatoscopic images.Journal of the American Academy of Dermatology 09/2008; 59(5):852-71. · 4.91 Impact Factor
