An attempt at a molecular prediction of metastasis in patients with primary cutaneous melanoma.
<h4>Background</h4>Current prognostic clinical and morphological parameters are insufficient to accurately predict metastasis in individual melanoma patients. Several studies have described gene expression signatures to predict survival or metastasis of primary melanoma patients, however...
