Perfil de expresión génica de 31 genes para el melanoma cutáneo: un panel de consenso de expertos

Purpose To review published literature on the clinical efficacy, use, and accuracy of the 31-gene expression profiling (31-GEP) test for prognostic information in invasive melanoma. Methods A comprehensive literature search used keywords "31-gene expression profiling," "melanoma," "prognosis," "clinical efficacy," and "clinical utility." A panel of 10 dermatologists with expertise in melanoma management reviewed the articles and created consensus statements. A modified Delphi process approved each statement, requiring supermajority approval through multiple rounds of real-time voting, with strength of recommendation assigned. Results The search produced 150 articles; 26 met inclusion criteria. The panel unanimously voted to adopt 9 consensus statements and recommendations regarding 31-GEP testing: 8 with strength "A" and 1 with strength "C." Conclusion The panel agreed there is strong support for using 31-GEP testing to provide prognostic information for invasive melanoma. The test provides prognostic information when thickness and other traditional factors are unknown, improves prognosis assessment when added to American Joint Committee on Cancer 8th edition staging system, and is associated with improved melanoma-specific mortality and overall survival. The panel concluded that the robust existing literature strongly supports its use as a best practice for appropriate patients with melanoma.
