Molecular Analysis of Uveal Melanoma

Onken et al report a prospective evaluation of a gene expression profiling (GEP)-based assay, designed around 15 genes, that assigns uveal melanoma (UM) to 2 prognostic subgroups: Classes 1 and 2, which respectively are associated with low and high risks of metastasis. In 260 UM patients, they compared GEP with detection of chromosome 3 loss of heterozygosity using a single nucleotide polymorphism (SNP) assay, stating that GEP is better at predicting metastatic risk. They also claim that GEP is more accurate than other cytogenetic- or molecular methods, which they dismiss (Read more...)
